Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Shown in Fig. 1 and Fig. 2, a kind of display register support, comprise base 5, column 6, support arm and head connector 1, first end and the base 5 of column 6 are rotationally connected mutually, second end of column 6 is flexibly connected with the first end of support arm, and head connector 1 is flexibly connected with the second end of support arm.
First key problem in technology of the present invention is, support arm comprises the first support arm 4 and the second support arm 3, the first end of the first support arm 4 and the second end chain connection of column 6, second end end face of the first support arm 4 is perpendicular to column 6, second end end face of the first support arm 4 is parallel to each other with the first end end face of the second support arm 3 and the second end end face of the second support arm 3 respectively, second end end face of the first support arm 4 and the first end end face of the second support arm 3 are connected, and the second end end face of the second support arm 3 and head connector 1 are connected.
Head connector comprises display device connecting plate, and display device is fixed on head connector display device connecting plate, and first end and the base of column are rotationally connected mutually, and realize, display device can do 180 degree of spinning movements around base.
Second end end face of the first support arm is provided with the first trepanning, and the first end end face of the second support arm is provided with the first pin coordinated with the first trepanning, the first pin is fixed on the first trepanning, realizes the second support arm around the first trepanning 360 degree rotation.And the second end end face of the first support arm, perpendicular to column, is also parallel to each other with the first end end face of the second support arm, increase its surface of contact, the bearing capacity of the first support arm and the second support arm is increased, effectively prevent Long-Time Service or display device heavier, cause the damage of support arm.
In like manner known, the second support arm and head connector also adopt aforesaid way to be connected, and further enhance the bearing capacity of support arm.
Further, head connector 1 is by ballhead connecting support arm.Therefore can realize head connector rotation, display device rotation mode is increased.
Technological scheme is further, and the joint of the first support arm 4 and the second support arm 3 was provided with line card 2; The joint of the second support arm 3 and head connector 1 was also provided with line card 2.
Further, base 5 was provided with cableties 14, the connecting line of display device is fixed by crossing line card and crossing cableties, easy to use, and structure is simple.
Further, base 5 is horizontally arranged with U-shaped fixture 13, the side of U-shaped fixture 13 is fixed on base 5 by fastening piece 15, forms draw-in groove, draw-in groove is provided with rubber cushion 12 bottom the opposite side of U-shaped fixture 13 and base 5.
By rotating fastening piece, the opposite side of this U-shaped fixture and base bottom relative position being moved, makes this draw-in groove fix desktop, and tightening fastener parts, make it fix.
Second key problem in technology is, the first support arm 4 comprises the first support arm 11, second support arm 19, first latch 10, second latch 22, the 3rd latch 23, the 4th latch 20 and connecting rod 21; The first end of the first support arm 11 is arranged in outside column 6, and is fixed by the first latch 10, is arranged with the second support arm 19 outside the second end of the first support arm 11, and is fixed by the second latch 22; The first end of connecting rod 21 is arranged in column 6, and is fixed by the 3rd latch 23, and the second end of connecting rod 21 is arranged in the second support arm 19, and is fixed by the 4th latch 20; Connecting rod 21 is positioned at the top of the first support arm 11.
By arranging connecting rod, the bearing capacity of the first strut is increased.Wherein, the first latch, the second latch, the 3rd latch, the 4th latch and the 5th latch are arranged in parallel.The tie point of column and the first strut, the tie point of the first strut and the second strut, the tie point of the second strut and connecting rod, and the tie point of connecting rod and column is in turn connected to form parallelogram.Wherein, the tie point of column and the first strut, and the tie point of connecting rod and column is fixing, namely parallelogram is fixing, and this parallelogram makes shape conversion according to this.
Therefore, display device is connected on a tie point, by changing the size of angle, realizing before and after display device and moving up and down, also can realize doing spinning movement (scope control is at-30 ° ~ 30 °) around tie point.
3rd key problem in technology is, is also connected with supporting mechanism between column 6 and the first support arm 4.
Further technological scheme is, supporting mechanism comprises air spring support plate 9, slide block 17, bolt 16, air spring 7 and the 5th latch 8; Air spring 7 is arranged on the inside of the first support arm 11, and is fixed by the second latch 22, and the output shaft of air spring 7 is connected with air spring support plate 9 by the 5th latch 8; Be provided with cavity in column 6, bolt 16 through cavity, and is threaded with column 6, and slide block 17 is arranged in cavity, and is threaded with bolt 16, and slide block 17 also connects air spring support plate 9.The both sides of the 5th latch 8 are respectively arranged with ball 24, the first support arm 11 are respectively arranged with the chute 25 coordinated with ball 24.
By arranging supporting mechanism, increasing the bearing capacity of the first support arm, improving the intensity of display register support further.The adjustment of parallelogram angular dimension is controlled by arranging air spring.Wherein, the output shaft of air spring connects the 5th latch, and stretched by air spring, adjusting angle, realizes before and after display device and move up and down, and also can realize doing spinning movement around tie point.
First support arm realizes angle adjustment by supporting mechanism, and ball slides in this chute, makes air spring adjustable extent become large.
Further, the head of bolt 16 and afterbody are threaded with column 6 respectively, and the middle part of bolt 16 is positioned at cavity.
Further, bolt 16 and column 6 are angularly arranged.Preferably, the angle ranging from 0 ~ 90 °.
Wherein, the head of bolt is fixed by gland nut 18, and gland nut is threaded with column.By rotating bolt, slide block is moved along bolt, and change the angle of air spring dunnage, thus change the loading angle of the first support arm active force (along on pressure rod air spring axial direction), thus regulate the first support arm bearing capacity.
Wherein, head and the afterbody of bolt are threaded with column respectively, and the middle part of bolt is positioned at cavity.Namely two of bolt is fixing, and slide block is positioned at cavity, and moves along bolt, the intensity of the first support arm is increased, effectively prevents the damage of the first support arm.
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.
