Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 4, the present invention is a kind of open air pressure support arm of electronic device stand, and as shown in Fig. 1 ~ 2, open air pressure support arm comprises adjustment seat 4, air pressure arm upper cover 1, air-leg 5, strut 3 and head connector 2;
Air pressure arm upper cover 1 has first end 11 and the second end 12, and air pressure arm upper cover 1 comprises a diapire 13 and two sidewalls 14, and its first end 11 is provided with pin-and-hole, and it is also provided with pin-and-hole 15 on the sidewall 14 of the second end 12; Strut 3 also has first end 31 and the second end 32, and its first end 31 and the second end 32 are equipped with pin-and-hole;
Head connector 2 comprises connecting head I 21 and connecting head II 22, and it is equipped with pin-and-hole; Air-leg 5 comprises pneumatic spring 53, and air-leg 5 has first end 51 and the second end 52, and its first end 51 and the second end 52 are equipped with pin-and-hole; One pin through the pin-and-hole on air pressure arm upper cover first end 11, the first end of air-leg 5 and connecting head I, by the first end of air pressure arm upper cover first end 11, air-leg 5 with connecting head I is movable couples together.One pin through the pin-and-hole on the first end 31 of strut 3 and connecting head II 22, by the first end 31 of strut 3 with connecting head II 22 is movable couples together.
As shown in Figure 3, adjustment seat 4 comprises roof 49, diapire 45 and has the sidewall 40 of opening, and the inner space that roof 49, diapire and sidewall 40 surrounds; The sidewall of adjustment seat open upper end both sides is provided with pin-and-hole 46 on a pair, and the sidewall of adjustment seat open lower end both sides is provided with a pair time pin-and-hole 47; Second end 12 of air pressure arm upper cover 1, through the pin-and-hole 15 on the sidewall of nearly second end of air pressure arm upper cover and the upper pin-and-hole 46 of adjustment seat, is connected with adjustment seat 4 is movable by one pin; Second end 32 of strut, through the lower pin-and-hole 47 of adjustment seat and the pin-and-hole of strut second end 32, is connected with adjustment seat 4 is movable by one pin.Because the pin-and-hole 15 on air pressure arm upper cover sidewall is arranged on the sidewall of the second end, so mounted adjustment seat 4 can be partially submerged in air pressure arm upper cover 1.
Adjustment seat 4 is also provided with adjusting screw 41 and regulating block 42, and adjustment seat roof 49 is provided with adjusting screw hole 48, and adjustment seat diapire 45 is provided with boss 451; A groove 43 is had at the edge of boss 451, adjusting screw 41 penetrates adjustment seat inner space from adjusting screw hole 48, regulating block 42 is arranged in adjustment seat inner space, regulating block 42 is connected by screw-thread fit with adjusting screw 41, the bottom of adjusting screw 41 is placed in groove 43 and then uses pressing plate retaining screw 441 by pressing plate 44 enclosed slot 43, make it formation hole, the bottom of adjusting screw 41 is fixed in this hole; Second end 52 of air-leg 5 is rotatably connected with regulating block 42, rotate adjusting screw 41 and can make relative movement between regulating block 42 and adjusting screw 41, thus regulating block 42 is moved up and down along adjusting screw 41, thus drive the second end 52 of air-leg 5 to move up and down, air-leg 5 is changed with the angle of air pressure arm upper cover 1, when the second end 52 of air-leg 5 is conditioned more downward, air-leg 5 is larger with the angle of air pressure arm upper cover 1, and the weight of the display screen that display bracket can support is larger; Otherwise when the second end 52 of air-leg 5 is conditioned more upwards, air-leg 5 is less with the angle of air pressure arm upper cover 1, and the weight of the display screen that display bracket can support is less.Because adjustment seat 4 is partially submerged in air pressure arm upper cover 1, for the ease of regulating the adjusting screw 41 of adjustment seat 4, being provided with in the position that the diapire 13 of air pressure arm upper cover 1 corresponds to adjustment seat adjusting screw hole 48 and regulating window 16, the upper and lower of regulating block 42 can be adjusted by regulating window 16 directly to rotate adjusting screw.
As shown in Figure 4, in use, the adjutage that adjustment seat of the present invention saves electronic device stand with visible adjusting screw is connected with fastening device, and head connector of the present invention is connected with display screen with three axle adjustable connecting devices.As mentioned above, the display screen of Different Weight, by rotating adjusting screw, makes regulating block drive air-leg second end to move up and down, makes it to change with the angle of air pressure arm upper cover thereupon, thus the weight size that adjustable pressure arm can support.
When needing the height regulating display screen, can lift or press down open air pressure support arm above, because air pressure arm upper cover 1, head connector 2, strut 3, adjustment seat 4 form mobilizable parallelogram, therefore upper lift or press down air pressure support arm time, this parallelogram can be out of shape thereupon, thus enables open air pressure support arm realize facing upward flexibly or nutation.
Simultaneously, in order to limit the maximum angle that open air pressure support arm is faced upward, spacing preiection I 17 is provided with in air pressure arm upper cover diapire 13, this spacing preiection I 17 is faced upward to contacting with the roof 49 of adjustment seat during special angle at open air pressure support arm and is offseted, thus open air pressure support arm is faced upward cannot continue to face upward to this special angle again.In the present embodiment, this special angle is set to 45 degree.Certainly this special angle also can be set as other angle, the size of its spacing angle can be set: the height of spacing preiection I 17 is larger, and spacing preiection I 17 contacts the angle that when offseting, open air pressure support arm is faced upward with the roof 49 of adjustment seat less by the height changing spacing preiection I 17; And the height of spacing preiection I 17 is less, spacing preiection I 17 contacts the angle that when offseting, open air pressure support arm is faced upward with the roof 49 of adjustment seat larger.
In order to limit the maximum angle of open air pressure support arm nutation, spacing preiection II 401 is provided with in the bottom of adjustment seat sidewall 40, this spacing preiection II 401 offsets to contacting with the lower edge of the sidewall 14 of air pressure arm upper cover during special angle at open air pressure support arm nutation, thus cannot continue nutation again after making open air pressure support arm nutation to this special angle.In the present embodiment, this special angle is set to 45 degree.Certainly this special angle also can be set as other angle, the size of its spacing angle can be set: as shown in Figure 4 by changing the setting position of spacing preiection II 401 on adjustment seat sidewall 40, the setting position of spacing preiection II 401 on adjustment seat sidewall 40 is higher, and spacing preiection II 401 contacts open air pressure support arm nutation when offseting angle with the lower edge of the sidewall 14 of air pressure arm upper cover is less; Otherwise the setting position of spacing preiection II 401 on adjustment seat sidewall 40 is lower, spacing preiection II 401 contacts open air pressure support arm nutation when offseting angle with the lower edge of the sidewall 14 of air pressure arm upper cover is larger.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
