AI Technical Summary
The existing manual adjustment display equipment base has poor stability due to insufficient spring force or excessive spring, which increases production costs and is difficult to adapt to display equipment of different weights.
A manual adjustment lifting base is designed, adopting a self-locking structure, including a spring, connecting rod, limiting block and rack. Through the limiting block, the rack is pressed under the action of the spring to limit the up and down movement of the lifting member. Users can adjust the height of the display device through simple up and down force.
It achieves simple operation and stability adapted to different display devices, simple structure and low cost, avoiding the increase in cost caused by the use of different springs.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting bases, in particular to a manually adjustable lifting base. Background Art
[0002] The base of the prior art manually adjustable display device usually uses a constant force spring, and the elastic force of the spring is used to adjust the display device. Since the display device has a certain weight, when the elastic force of the spring is too small, the display device cannot be supported. When the elastic force of the spring is too large, the mobile display device will rebound unstably. Therefore, in order to adapt to display devices of different weights, different constant force springs need to be used in the base, which increases the production cost. Utility Model Content
[0003] In view of this, the utility model hopes to provide a manually adjustable lifting base, which is easy to operate, can be adapted to different display devices, has good stability, simple structure and low cost.
[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:
[0005] The utility model provides a manually adjustable lifting base, comprising a base plate, a column, a lifting piece and a self-locking structure, wherein the self-locking structure comprises a spring, four connecting rods, a limit block and a rack, wherein the limit block is provided with limit teeth matching the teeth on the rack, the rack is installed in the column, the two sides of the limit block are respectively connected to the two connecting rods, the other side of the connecting rod is connected to the lifting piece, one end of the spring is connected to the lifting piece, and the other end is connected to the limit block, the limit block presses the rack under the action of the spring, the column is connected to the base plate, and the lifting piece is connected to the display device.
[0006] Furthermore, the number of the springs is one or more.
[0007] Furthermore, the teeth on the rack are asymmetrical on both sides.
[0008] Furthermore, the connecting rod is detachably connected to the lifting member and the limiting block via screws.
[0009] The beneficial effects of the utility model are as follows:
[0010] The utility model adopts a self-locking structure, in which the limit block presses the rack under the action of the spring, thereby limiting the up and down movement of the lifting member. The user only needs to apply force upward or downward to adjust the display device to the required height. The operation is simple, and the self-locking structure is highly universal and can be adapted to different display devices.
[0011] The movement of the limit block in the self-locking structure of the utility model adopts a four-link structure, so that the limit block can be moved up and down, and the force is better received.
[0012] The two sides of the teeth on the rack in the utility model are asymmetrical, so that the upward lifting is easy, the downward pressure is large, and the stability is better.
[0013] The utility model has a simple structure and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Among them: 1 is a base plate, 2 is a column, 3 is a lifting member, 4 is a self-locking structure, 41 is a spring, 42 is a connecting rod, 43 is a limiting block, 431 is a limiting tooth, and 44 is a rack. DETAILED DESCRIPTION
[0018] In order to more thoroughly understand the features and technical contents of the present invention, the implementation of the present invention is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not intended to limit the present invention.
[0019] like Figure 1-3 As shown, a manually adjustable lifting base according to an embodiment of the utility model includes a base plate 1, a column 2, a lifting member 3 and a self-locking structure 4, wherein the self-locking structure 4 includes two springs 41, four connecting rods 42, a limit block 43 and a rack 44, wherein the limit block 43 has a limit tooth 431 matching the teeth on the rack 44, and the rack 44 is installed in the column 2, and the two sides of the limit block 43 are respectively connected to the two connecting rods 42 by screws, and the other side of the connecting rod 42 is connected to the lifting member 3 by screws, one end of the two springs 41 is connected to the lifting member 3, and the other end is connected to the limit block 43, and the limit block 43 presses the rack 44 under the action of the two springs 41, the column 2 is connected to the base plate 1, and the lifting member 3 is connected to the display device.
[0020] In the embodiment of the utility model, the limit block 43 presses the rack 44 under the action of the spring 41, thereby limiting the up and down movement of the lifting member 2, thereby fixing the display device at a required height. When lifting, the lateral force of the inclined surface on the rack 44 forces the limit block 43 to move laterally, thereby releasing the limit. Similarly, when pressing down, the lateral force of the inclined surface on the rack 44 forces the limit block 43 to move laterally, thereby releasing the limit; and the movement of the limit block 43 uses a four-bar structure, which can make the limit block 43 move up and down and bear force better; the shape of the teeth on the rack 44 can be asymmetrical, so that lifting is easy, the downward pressure is large, and the stability is better.
[0021] The utility model has a simple structure and low cost. It adopts a self-locking structure 4. The limit block 43 presses the rack 44 under the action of the spring 41, thereby limiting the up and down movement of the lifting member 2. The user only needs to apply force upward or downward to adjust the display device to the required height. The operation is simple, and the self-locking structure 4 is highly universal and can adapt to different display devices.
[0022] Here, the specific models of the above-mentioned devices are not limited or described in detail, and the in-depth connection methods of the above-mentioned devices are not described in detail. As common knowledge, technicians in this field can understand it.
