[0033] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] See also Figures 1 to 5 shown.

[0036] This embodiment provides a non-slide rail lifting bracket, which uses a connecting rod instead of a slide rail for lifting. It not only has the advantages of simple structure and low cost, but also has better smoothness of lifting, thereby extending the service life of the product.

[0037] Specifically, the non-slide rail lifting bracket includes a fixing frame 13, a spindle 28 is installed on one side of the fixing frame 13, and the spindle 28 is rotatably connected with a first connecting rod 19 and a second connecting rod 18. Optionally, the first connecting rod 19 and the second connecting rod 18 are sleeved on the spindle 28, and a friction plate and a nut for adjusting the tightness and rotation torque can also be sleeved on the spindle 28.

[0038] The first end of the first connecting rod 19 is connected to the first elastic member 16, and the second end is connected to the first support frame 22. 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 second connecting rod 18 is connected to the second elastic member 17, and the second end is connected to the second support frame 23. The end of the second elastic member 17 away from the second connecting rod 18 is fixedly connected to the fixing frame 13. Figure 1 and Figure 2 It should be noted that Figure 1 and Figure 2 In order to illustrate 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 connecting rod 19 , and the second elastic member 17 is not connected to the second connecting rod 18 .

[0039] 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 connecting rod 19 and the second connecting rod 18 can be designed to rotate synchronously. For example, a vertically arranged guide shaft 21 is also installed on one side of the fixed frame 13, and a sliding block 20 is sleeved and slidably connected on the guide shaft 21; the sliding block 20 is also connected to the first sub-rod 14 and the second sub-rod 15, and the end of the first sub-rod 14 away from the sliding block 20 is connected to the first end of the first connecting rod 19, and the end of the second sub-rod 15 away from the sliding block 20 is connected to the first end of the second connecting rod 18. In this way, when any one of the first connecting rod 19 and the second connecting rod 18 rotates around the spindle 28, under the joint action of the first sub-rod 14, the second sub-rod 15, the sliding block 20 and the guide shaft 21, the other one rotates synchronously around the spindle 28, thereby realizing the synchronous rotation movement of the first connecting rod 19 and the second connecting rod 18, which greatly improves the stability and smoothness of the lifting process.

[0040] Furthermore, in order to improve the compactness and stability of the structure, the first auxiliary rod 14 and the second auxiliary rod 15 can be respectively arranged on both sides of the sliding block 20, such as Figure 1 shown.

[0041] As an optional implementation of this embodiment, a limit stopper 29 is provided at the top end of the guide shaft 21 to limit the maximum height of the sliding block 20. Specifically, in order to prevent the non-slide rail lifting bracket from tipping over, it is necessary to limit the angle range between the first connecting rod 19 and the second connecting rod 18. Therefore, when the angle between the first connecting rod 19 and the second connecting rod 18 is reduced to the minimum allowable value, the limit stopper 29 blocks the sliding block 20 to prevent the sliding block 20 from continuing to rise. In this embodiment, another limiting structure is also provided, which can also limit the angle range between the first connecting rod 19 and the second connecting rod 18. Specifically, a first arc-shaped limit groove 26 and a second arc-shaped limit groove 27 are provided on one side of the fixing frame 13. The first connecting rod 19 passes through the first arc-shaped limit groove 26 and is limited to being able to rotate only within the arc range of the first arc-shaped limit groove 26. The second connecting rod 18 passes through the second arc-shaped limit groove 27 and is limited to being able to rotate only within the arc range of the second arc-shaped limit groove 27. Figure 3 shown.

[0042] 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 other shapes, but should at least have a first connecting portion connected to the elastic member, a second connecting portion connected to the support frame, and a rotating connecting portion connected to the spindle 28 between the first connecting portion and the second connecting portion.

[0043] 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 in stably supporting the display screen 10 .

[0044] As an optional implementation of this embodiment, the first support frame 22 and the second support frame 23 are both provided with cavities at the connection. Specifically, the first support frame 22 has a first connection member 24 installed in the internal cavity for fixedly connecting the first connecting rod 19, and the second support frame 23 has a second connection member 25 installed in the internal cavity 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 weight and cost, but also can conceal the first connection member 24 and the second connection member 25, thereby improving the aesthetics of the product.

[0045] As an optional implementation of this embodiment, the first elastic member 16 and the second elastic member 17 are both tension springs.

[0046] As an optional implementation of this embodiment, the maximum distance between the support points of the first support frame 22 and the support points 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 points of the first support frame 22 and the support points of the second support frame 23 is as follows: Figure 5 As shown, this design can prevent the non-slide rail lifting bracket from occupying too much space.

[0050] The second rotating component 11 has one side connected to the first rotating component 12 and the other side used to connect to the display screen 10 .

[0051] The first rotating assembly 12 is used to adjust the pitch and elevation angles of the display screen 10, and the second rotating assembly 11 is used to adjust the horizontal and vertical screen states of the display screen 10. It should be noted that the prior art has provided many specific implementations of the first rotating assembly 12 and the second rotating assembly 11, which will not be repeated here.
