In order to make the purposes, features and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the following description The embodiments described above are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1

Please refer to Figure 1 to Figure 5.

This embodiment provides a non-sliding rail lifting bracket, which uses the connecting rod form to replace the sliding rail for lifting, which not only has the advantages of simple structure and low cost, but also has better smoothness of the lifting form and prolongs the service life of the product.

Specifically, the non-sliding rail lifting bracket includes a fixing frame 13 , a mandrel 28 is mounted on one side of the fixing frame 13 , and the first connecting rod 19 and the second connecting rod 18 are rotatably connected to the mandrel 28 . Optionally, the first connecting rod 19 and the second connecting rod 18 are sleeved on the mandrel 28, and the mandrel 28 can also be sleeved with a friction plate and a nut for adjusting the tension and rotational torque.

The first end of the first connecting rod 19 is connected with the first elastic member 16, the second end is connected with the first support frame 22, and the end of the first elastic member 16 away from the first connecting rod 19 is fixedly connected to the fixing frame 13; The first end of the rod 18 is connected with a second elastic member 17, the second end is connected with a second support frame 23, and the end of the second elastic member 17 away from the second connecting rod 18 is fixedly connected to the fixing frame 13, as shown in Figures 1 and 2 shown. It should be noted that, in FIGS. 1 and 2 , in order to show the structures of the first elastic member 16 and the second elastic member 17 , the first elastic member 16 is not connected to the first link 19 , and the second elastic member 17 is not connected to the second link 18 .

As an optional implementation of this embodiment, when adjusting the height of the display screen 10, in order to improve the stability of the structure, the first link 19 and the second link 18 can be designed to rotate synchronously. For example, a vertically arranged guide shaft 21 is also installed on one side of the fixing frame 13, and a sliding block 20 is sleeved and slidably connected to the guide shaft 21; the sliding block 20 is also connected with the first auxiliary rod 14 and the second auxiliary rod 15 One end of the first sub-rod 14 away from the sliding block 20 is connected to the first end of the first link 19 , and one end of the second sub-rod 15 away from the sliding block 20 is connected to the first end of the second link 18 . In this way, when any one of the first link 19 and the second link 18 rotates around the spindle 28, under the combined action of the first sub-rod 14, the second sub-rod 15, the sliding block 20 and the guide shaft 21 , and the other rotates synchronously around the mandrel 28 , thereby realizing the synchronous rotation of the first connecting rod 19 and the second connecting rod 18 , which greatly improves the stability and smoothness of the lifting process.

Further, in order to improve the compactness and stability of the structure, the first sub-rod 14 and the second sub-rod 15 may be disposed on two sides of the sliding block 20 respectively, as shown in FIG. 1 .

As an optional implementation of this embodiment, a limit stop 29 is provided at the top of the guide shaft 21 to limit the maximum height of the sliding block 20 . Specifically, in order to prevent the non-sliding rail lifting bracket from tipping over, it is necessary to limit the included angle range between the first link 19 and the second link 18 . Therefore, when the angle between the first link 19 and the second link 18 is reduced to the minimum allowable value, the limit block 29 blocks the sliding block 20 and prevents the sliding block 20 from continuing to rise. In this embodiment, another limiting structure is also provided, which can also limit the included angle range between the first connecting rod 19 and the second connecting rod 18 . Specifically, one side of the fixing frame 13 is provided with a first arc-shaped limiting groove 26 and a second arc-shaped limiting groove 27 , and the first connecting rod 19 passes through the first arc-shaped limiting groove 26 and is restricted by In order to only be able to rotate within the arc range of the first arc-shaped limiting groove 26, the second link 18 passes through the second arc-shaped limiting groove 27 and is limited to only be able to rotate within the second arc-shaped limiting groove. 27 radians, as shown in Figure 3.

Further, the first connecting rod 19 and the second connecting rod 18 are both L-shaped connecting rods. It should be understood that the L-shaped connecting rod is only a preferred embodiment, and the first connecting rod 19 and the second connecting rod 18 can also be of other shapes, but should at least have a first connecting part for connecting the elastic member and a connecting support frame The second connecting part of the 1 and the rotating connecting part of the connecting spindle 28 between the first connecting part and the second connecting part.

It should be understood that, in this embodiment, the specific shapes of the first support frame 22 and the second support frame 23 are not limited, as long as their shapes can play a role of stably supporting the display screen 10 .

As an optional implementation of this embodiment, both the first support frame 22 and the second support frame 23 are provided with cavities at the joints. The first connecting member 24 of the connecting rod 19 and the inner cavity of the second support frame 23 are installed with a second connecting member 25 for fixedly connecting the second connecting rod 18 . The first support frame 22 and the second support frame 23 with cavities can not only reduce the weight and cost, but also can install the first connector 24 and the second connector 25 in a concealed manner, thereby improving the aesthetics of the product.

As an optional implementation of this embodiment, the first elastic member 16 and the second elastic member 17 are both tension springs.

As an optional implementation of this embodiment, the maximum distance between the support point of the first support frame 22 and the support point of the second support frame 23 is less than or equal to the width of the display screen 10 . The maximum distance between the support point of the first support frame 22 and the support point of the second support frame 23 is shown in FIG. 5 , and this design can prevent the non-sliding rail lifting frame from occupying too much space.
