AI Technical Summary
Existing swivel chairs, while flexible enough, are not conducive to concentration when focused work is required, making it difficult to maintain static focus.
Design a chair with a rotatable backrest. Through the combined use of slide rails, ring blocks, limit components, springs, sliders, connecting rods, mounting plates, and pull blocks, the backrest can be rotated and locked to meet the needs of different working states.
It provides convenience for communication and allows for focus during work. The backrest is locked by the engagement of the limit block and the elasticity of the spring, meeting different usage needs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture technology, and in particular to a chair with a rotatable backrest. Background Technology
[0002] Furniture is ubiquitous in daily life and plays many roles in people's lives. It mainly includes chairs, benches, tables, sofas, etc., among which chairs are one of the many types of furniture.
[0003] Most offices are equipped with a number of chairs, with swivel chairs being the most common. Swivel chairs can rotate 360°, making it easier to communicate with colleagues. However, when it comes to concentrating on work, most of the time it is necessary to remain static to think or stay focused, and the flexibility of swivel chairs is actually not conducive to the worker's concentration.
[0004] Therefore, it is necessary to invent a chair with a rotatable backrest to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a chair with a rotatable backrest to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a chair with a rotatable backrest, including a seat plate, an annular groove at the bottom of the seat plate, a slide rail connected in the annular groove, a backrest connected in the slide rail, an annular block connected to the bottom of the seat plate, a plurality of limiting holes on one side of the annular block, two L-shaped connecting plates connected to the bottom of the backrest, an installation groove on one side of the L-shaped connecting plates, a limiting component provided in the installation groove, a support column connected to the bottom of the seat plate, and a base connected to the bottom of the support column.
[0007] Preferably, the limiting component includes a spring connected to the inner wall of the mounting groove, the inner wall of the mounting groove has a sliding groove, a slider is connected in the sliding groove, a mounting plate is connected to the top of the slider, two connecting rods are connected to one side of the mounting plate, a pull block is connected to one side of the connecting rods, a limiting block corresponding to the limiting opening is connected to one side of the mounting plate, and an opening corresponding to the limiting block is opened on one side of the L-shaped connecting plate.
[0008] Preferably, the base is connected to an anti-slip pad at its bottom.
[0009] The technical effects and advantages of this utility model are as follows: By setting up a slide rail, backrest, annular block, limiting component, spring, slider, connecting rod, mounting plate, pull block, and limiting block for coordinated use, when the backrest needs to be rotated, the pull block is pulled outward, and the slider is driven by the connecting rod and mounting block to move the limiting block out of the limiting hole in the annular block. The backrest can then be rotated by the slide rail. Releasing the pull block will cause the slider to move due to the elasticity of the spring, which will lock the limiting block into one of the limiting holes in the annular block, thus locking the backrest. This allows the user to control the rotation and locking of the backrest according to their needs, providing convenience during communication with colleagues and enabling them to maintain focus during work.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This utility model provides, for example Figure 1-5The chair shown includes a seat plate 1, an annular groove at the bottom of the seat plate 1, a slide rail 2 connected to the annular groove, a backrest 3 connected to the slide rail 2, an annular block 4 connected to the bottom of the seat plate 1, multiple limiting holes on one side of the annular block 4 to lock the backrest 3, two L-shaped connecting plates 5 connected to the bottom of the backrest 3, an installation groove on one side of the L-shaped connecting plate 5, a limiting component 6 installed in the installation groove, a support column 7 connected to the bottom of the seat plate 1, and a base 8 connected to the bottom of the support column 7.
[0018] The limiting component 6 includes a spring 9 connected to the inner wall of the mounting groove. The inner wall of the mounting groove has a sliding groove, and a slider 10 is connected in the sliding groove. The top of the slider 10 is connected to a mounting plate 11. Two connecting rods 12 are connected to one side of the mounting plate 11, and a pull block 13 is connected to one side of the connecting rods 12. A limiting block 14 corresponding to the limiting opening is connected to one side of the mounting plate 11. An opening corresponding to the limiting block 14 is opened on one side of the L-shaped connecting plate 5, which can control the rotation and locking of the backrest 3.
[0019] The base 8 has an anti-slip pad 15 attached to its bottom to increase the chair's anti-slip performance.
[0020] The working principle of this utility model is as follows: When the backrest needs to be rotated, pull the pull block outward. Through the connecting rod and mounting block, the slider is driven to move the limiting block out of the limiting hole in the annular block. The backrest can then be rotated through the slide rail. When the pull block is released, the spring force will push the slider to move, which will lock the limiting block into one of the limiting holes in the annular block, thus locking the backrest.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
