Description

Technical Field

[0001] The utility model relates to the technical field of display brackets, in particular to a display bracket with a novel four-link structure. Background Art

[0002] The traditional four-bar linkage is primarily composed of a cantilever die-casting, connecting rod, and spacer. The spacers are connected by a small pin, and the connecting rod is mounted on the pin. The main die-casting and spacer are assembled together through a large axis. The head die-casting and column die-casting are mounted on the top and bottom axis, respectively.

[0003] The traditional structure has the following disadvantages:

[0004] 1. There are many parts, resulting in a large idle stroke of the mechanism. During the movement of the mechanism, there is an idle stroke between the die casting and the axis, between the axis and the gasket, between the gasket and the pin, between the pin and the connecting rod, between the head die casting and the axis, and between the column die casting and the axis;

[0005] 2. Assembly is difficult. During the assembly process, the gasket, pin, connecting rod, cantilever die-casting, head die-casting, and column die-casting must be placed in the correct position first, and finally the entire axis must be passed through. During the penetration process, the position of the parts is easy to deviate, making assembly difficult. Utility Model Content

[0006] In view of this, the present invention hopes to provide a new monitor stand with a four-link structure, which can improve the idle stroke and simplify the assembly process of the monitor stand.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0008] The utility model provides a novel monitor stand with a four-link structure, comprising a base, a head die-casting, two connecting rods, two cantilever die-castings, a column die-casting, a tension spring, a tension spring fixing member, and a cantilever fixing member; the head die-casting comprises a first axis and a first fixing pin integrally formed by injection molding with the head die-casting, and the column die-casting comprises a second axis and a second fixing pin integrally formed by injection molding with the column die-casting;

[0009] Both ends of each connecting rod are connected to the first fixing pin and the second fixing pin respectively, and the two connecting rods are symmetrically mounted on both sides of the head die casting and the column die casting respectively through the first fixing pin and the second fixing pin;

[0010] Two ends of each cantilever die casting are respectively connected to the first axis and the second axis, and the two cantilever die castings are symmetrically installed on both sides of the head die casting and the column die casting through the first axis and the second axis;

[0011] The tension spring fixing member is connected to the two connecting rods, the cantilever fixing member is connected to the two cantilever die-castings, one end of the tension spring is connected to the tension spring fixing member, and the other end is connected to the cantilever fixing member;

[0012] The bottom of the column die-casting is connected to the base, and one end of the head die-casting is connected to the display.

[0013] Furthermore, the number of the tension springs is one or more.

[0014] Furthermore, both ends of the first axis and the second axis are provided with threads, and after the two cantilever die-castings are installed, nuts are installed at the threads to fasten the cantilever die-castings.

[0015] Furthermore, the tension spring fixing member is detachably connected to the two connecting rods via screws, and the cantilever fixing member is detachably connected to the two cantilever die-castings via screws.

[0016] The beneficial effects of the utility model are as follows:

[0017] (1) The utility model reduces the idle stroke by splitting the original integrated cantilever die casting into two parts. The axis and the head die casting and the column die casting are replaced by buried injection. The fixing pins are also buried directly in the head and column die castings, thereby reducing the original assembly gap between the axis and the head and column die castings. At the same time, the eight gaskets required for the original assembly are eliminated, greatly reducing the number of parts and thus reducing the idle stroke.

[0018] (2) The assembly of the utility model is simplified. There is no need to put many parts in position and then insert the axis as in the original method. It is only necessary to put the two cantilever die-castings on the axis of the head and column die-castings from both sides in turn, which makes the assembly simpler and more convenient.

DETAILED DESCRIPTION

[0026] In order to enable a more detailed understanding of the features and technical contents of the present invention, the implementation of the present invention is described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference only and are not intended to limit the present invention.

[0027] like Figure 1-6 As shown, an embodiment of the utility model is a display stand with a novel four-link structure, including a base 1, a head die-casting 2, two connecting rods 4, two cantilever die-castings 5, a column die-casting 3, eight tension springs 6, a tension spring fixing part 7 and a cantilever fixing part 8; the bottom of the column die-casting 3 is connected to the base 1, and one end of the head die-casting 2 is connected to the display 9.

[0028] The head die casting 2 includes a first axis 21 and a first fixing pin 22 which are integrally formed by embedding injection molding with the head die casting 2 , and the column die casting 3 includes a second axis 31 and a second fixing pin 32 which are integrally formed by embedding injection molding with the column die casting 3 .

[0029] The two ends of each connecting rod 4 are respectively connected to the first fixing pin 22 and the second fixing pin 32, and the two connecting rods 4 are symmetrically installed on both sides of the head die-casting 2 and the column die-casting 3 through the first fixing pin 22 and the second fixing pin 32; the two connecting rods 4, the first fixing pin 22 and the second fixing pin 32 form a four-bar linkage.

[0030] The two ends of each cantilever die-casting 5 are respectively connected to the first axis 21 and the second axis 31, and the two cantilever die-castings 5 ​​are symmetrically installed on both sides of the head die-casting 2 and the column die-casting 3 through the first axis 21 and the second axis 31; the two cantilever die-castings 5, the first axis 21 and the second axis 31 form a four-bar linkage.

[0031] The tension spring fixing part 7 is detachably connected to the two connecting rods 4 by screws, and the cantilever fixing part 8 is detachably connected to the two cantilever die-castings 5 ​​by screws. One end of each tension spring 6 is connected to the tension spring fixing part 7, and the other end is connected to the cantilever fixing part 8 to provide strength for supporting the weight of the display.

[0032] Both ends of the first axis 21 and the second axis 31 are provided with threads. After the two cantilever die-castings 5 ​​are installed, the cantilever die-castings 5 ​​are tightened by installing nuts 10 at the threads. By adjusting the friction generated by the nuts 10 and the weight of the display 9 being neutralized by the force generated by the tension spring 6, the display bracket can be stopped at any position.

[0033] Assembly process: The utility model does not need to put many parts in position and then pass the axis as before. It only needs to install two connecting rods 4 and two cantilever die-castings 5 ​​on the head die-casting 2 and the column die-casting 3 from both sides respectively; then install the tension spring 6, and fix the tension spring fixing part 7 and the cantilever fixing part 8 on the connecting rod 4 and the cantilever die-casting 5 respectively with screws. The bottom of the column die-casting 3 is fixed to the base 1, and one end of the head die-casting 2 is connected to the monitor 9. After all adjustments and installations are completed, screw the nut 10 on the threads on the first axis 21 of the head die-casting 2 and the second axis 31 of the column die-casting 3 to fix it; the lifting method of the display bracket of the utility model is provided by two four-bar mechanisms. The four bars are combined to form a quadrilateral. The bottom edge of the quadrilateral is fixed to the base through the column die-casting, and the top edge of the quadrilateral is fixed to the monitor through the head die-casting. A tension spring is provided inside to provide strength to support the weight of the monitor. The display bracket of the present invention can stop at any position by adjusting the friction force generated by the nut 10 and the weight of the display 9 being neutralized by the force generated by the tension spring 6.

[0034] The utility model reduces the idle stroke and splits the originally integrated cantilever die-casting into two. The first axis 21 and the first fixing pin 22 are embedded in the head die-casting 2 and formed as an integral part, and the second axis 31 and the second fixing pin 32 are embedded in the column die-casting 3 and formed as an integral part, thereby reducing the original assembly gap between the axis and the head and column die-castings, and at the same time eliminating the eight gaskets required for the original assembly, greatly reducing the number of parts, and thus reducing the idle stroke.

[0035] The utility model simplifies assembly. There is no need to put many parts in position and then insert the axis as in the original method. It is only necessary to put the two cantilever die-castings 5 ​​on the axes of the head die-casting 2 and the column die-casting 3 from both sides in turn, which makes assembly simpler and more convenient.
