The specific embodiment
In order to make those skilled in the art person understand better technical scheme of the present invention, be described in further detail below in conjunction with drawings and Examples.
Structure such as Fig. 1, Fig. 2 and shown in Figure 3 of the embodiment of lamp casing of the present invention and change gap hinge, comprise two bearing pins 1, two positioning sleeves 2, two axis pin bases 3, two back-moving springs 4, two spring cappings 5, a hinge seat 6 among the figure, and upper casing 7 and lower casing 8.
Among the figure, it is hinged with upper casing 7 and the lower casing 8 of lamp casing to become the gap hinge.The hinge seat 6 and the lower casing 8 that become the gap hinge are connected as a single entity, and hinge seat 6 is positioned at the middle part of lower casing 8 edges one side; The axis pin base 3 and the upper casing that become the gap hinge are connected as a single entity, and axis pin base 3 is positioned at the two ends of the corresponding hinge seat 6 in upper casing 7 edges.
The concrete structure that becomes the gap hinge is as follows.
Bearing pin 1 passes axis pin base 3, two axis pin bases 3 is hinged on the two ends of hinge seat 6.Bearing pin 1 can move axially with respect to axis pin base 3 and hinge seat 6, is provided with the detent mechanism that bearing pin 1 moves between bearing pin 1 and the axis pin base 3.
Bearing pin 1 is provided with external screw thread 11 away from a section of hinge seat 6, and footpath, the externally threaded end is greater than the diameter of optical axis, and the end of bearing pin 1 thread segment is provided with knob 12, is used for transmitting pulling force and the torsion that the user produces with manual operation.
The critical component of detent mechanism is the positioning sleeve 2 that is arranged between bearing pin 1 and the axis pin base 3, and the endoporus of positioning sleeve 2 is provided with internal thread, and positioning sleeve 2 rotation sets are on the external screw thread 11 of bearing pin 1.
Positioning sleeve 2 is provided with the semi-circular step 21 that cooperates with axis pin base 3 ends away from the end of hinge seat 6; The end of axis pin base 3 is provided with the semi-circular boss 31 corresponding with semi-circular step 21.When bearing pin 1 moved axially towards hinge seat 6, semi-circular step 21 is symmetrical in opposite directions and location with semi-circular boss 31; When bearing pin 1 away from hinge seat 6 moved axially, semi-circular step 21 can overlap and locate with semi-circular boss 31.
The centre at semi-circular boss 31 tops of axis pin base 3 ends is provided with lock tab 32; The centre of the semi-circular step 21 of positioning sleeve 2 is provided with the latch recess 22 that matches with lock tab 32.When semi-circular step 21 overlaped with semi-circular boss 31, lock tab 32 entered latch recess 22.
When spurring the knob of bearing pin 1 end, positioning sleeve 2, spring capping 5 are done moving axially of away from hinge seat 6 with bearing pin 1 with respect to axis pin base 3, and back-moving spring 5 is compressed.When the lower plane of the semi-circular step 21 of positioning sleeve 2 ends is higher than the upper plane of the lock tab 32 on the semi-circular boss 31 in axis pin base 3 ends, if turning knob 180 degree, latch recess 22 on the semi-circular step 21 can be alignd with lock tab 32, at this moment decontrol knob, lock tab 32 enters latch recess 22, and semi-circular step 21 overlaps with semi-circular boss 31.Such as Fig. 4, shown in Figure 5.
Again spur the knob of bearing pin 1 thread head, and decontrol after rotating 180 degree, under the effect of back-moving spring 5, positioning sleeve 2, spring capping 5 are done moving axially towards hinge seat 6 with bearing pin 1 with respect to axis pin base 3, back-moving spring 5 is released, and semi-circular step 21 is symmetrical in opposite directions and location with semi-circular boss 31.
The inward at both ends of hinge seat 6 is provided with bearing pin 1 and cooperates the reducing hole, and two reducing holes are coaxial.The reducing hole is divided into macropore section 61, taper hole section 62 and aperture section 63 successively.Bearing pin 1 is after hinge seat 6 moves axially, and bearing pin 1 enters aperture section 63 through macropore section 61 and the taper hole section 62 in reducing hole, and bearing pin 1 is less with the fit clearance of aperture section 63.After bearing pin 1 away from hinge seat 6 moved axially, bearing pin 1 withdrawed from the aperture section 63 in reducing hole, gets back to macropore section 61 by taper hole section 62, and bearing pin 1 is larger with the fit clearance of macropore section 61.
The assembling process of the embodiment of the invention.
1. first positioning sleeve 2 is assembled in the axis pin base 3 that links together with upper casing 7, the semi-circular step 21 of positioning sleeve 2 ends that assemble and the semi-circular boss 31 of axis pin base 3 ends be symmetrical the cooperation in opposite directions.
2. back-moving spring 4 is assembled in the cavity between positioning sleeve 2 and the axis pin base 3, it is fixing to use spring capping 5 to be screwed on the external screw thread of positioning sleeve 2 afterbodys, and back-moving spring 4 is covered.
3. after two of upper casing 7 axis pin bases 3 all install, will and the hinge seat 6 that links together of lower casing 8 place between two axis pin bases 3, bearing pin 1 is screwed in the positioning sleeve 2, to revolve motionless till.Just finished the assembling process of lamp casing.
The using method of the embodiment of the invention.
1. after the upper casing of light fixture and lower casing are built, the semi-circular step 21 of positioning sleeve 2 ends just in time with the semi-circular boss 31 of axis pin base 3 ends symmetrical cooperation in opposite directions, and be aligned in same plane.Bearing pin 1 is inserted into the aperture section 63 in hinge seat 6 reducing holes, and the aperture size of aperture section 63 is a bit larger tham the external diameter of bearing pin 1, and bearing pin 1 just is little matched in clearance with hinge seat 6, about the about 0.1mm in gap.
2. when light fixture will be changed parts and need open upper casing 7, with hand bearing pin 1 is pulled up, bearing pin 1 drives positioning sleeve 2 and moves axially together.When the lower plane of the semi-circular step 21 of positioning sleeve 2 is higher than the upper plane of the lock tab 32 on the axis pin base 3 semi-circular boss 31, rotating pin 1.After rotating 180 degree, bearing pin 1 is fallen, the lock tab 32 on the semi-circular boss 31 just in time enters in the latch recess 22 on the semi-circular step 21.Relative motionless between bearing pin 1 and the positioning sleeve 2, at this moment bearing pin 1 is extracted out from the aperture section 63 in the reducing hole of hinge seat 6 and is got back in the macropore section 61, and bearing pin 1 increases with the fit clearance of hinge seat 6, at this moment just can rotate upper casing 7 or the lower casing 8 of light fixture, and hinge is movable flexible.
3. after lower casing 8 closes with upper casing 7, bearing pin 1 is driven positioning sleeve 2 pull-ups, rotate 180 degree, bearing pin 1 passes through the elastic reset of back-moving spring 4 to initial position with positioning sleeve 2, bearing pin 1 is inserted into the aperture section 63 in reducing hole by the taper hole section 62 in hinge seat 6 reducing holes, the adjustment of the relative position between pulling lower casing 8 and the upper casing 7, the accurate location of realizing lower casing 8 and upper casing 7.
Foregoing is preferred embodiment of the present invention only, is not the present invention is carried out the scope restriction.Those skilled in the art can carry out corresponding flexible or modification very easily according to main design of the present invention and spirit.Such as hinge seat the straight hole that cooperates with bearing pin can be set, bearing pin is provided with the multidiameter shaft that cooperates with the straight hole of hinge seat, by the different-diameter section of multidiameter shaft and cooperating of hinge seat, reaches the Variable between bearing pin and the hinge seat.So protection scope of the present invention should be as the criterion with the covering scope of claim.
