Description

Technical Field

[0001] The utility model belongs to the technical field of chair back support connectors, and particularly relates to a chair with a chair back support connector. Background Art

[0002] With the development of the economy, people's requirements for the office environment are getting higher and higher. Office furniture has an increasingly broad market in China. As one of the main office furniture, office chairs are widely used in people's work and life, and are generally recognized and loved by people. They are one of the essential furniture in modern office and home environments.

[0003] In the prior art, the backrest of a chair is usually fixed to the chair. However, different people have different sitting postures and body center-of-gravity positions in different situations. This causes the stress point of the chair backrest to shift to one side, and the user's body weight will be squeezed on one side. Moreover, it is not easy to adjust the chair backrest left and right, making it easy for users to feel uncomfortable during the use of the chair. In addition, applying force on one side of the chair backrest for a long time will cause the chair backrest to deform and reduce the service life of the chair.

[0004] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.

Detailed implementation manners

[0023] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 4 shown, a seat with a backrest support connector in an embodiment of the present utility model includes: a seat 1, a support mechanism 2, and a fixing mechanism 3.

[0025] As Figure 1 shown, the seat 1 is used to support the human body. A backrest 101 is provided above the seat 1, and the backrest 101 is used to support the human back. The support mechanism 2 is installed on the seat 1, and the support mechanism 2 includes a fixing block 201, and the fixing block 201 is used to support the support rod 202.

[0026] As Figures 1 to 3 shown, the support rod 202 is rotatably connected to the fixing block 201, and the support rod 202 is used to support the fixing frame 207 and the buffer spring 209. A support block 203 is slidably connected inside the support rod 202, and the support block 203 can slide inside the support rod 202, so as to drive the slider 204 and the fixing rod 205 to move under the push of the connecting rod 206.

[0027] As Figures 2 to 3As shown, a pair of sliders 204 are fixed on the support block 203. The fixed rod 205 can be supported on the side wall of the support rod 202, making it difficult for the support rod 202 to rotate on the support block 203. The fixed rod 205 is fixed on the slider 204 and is used to support one end of the connecting rod 206.

[0028] As Figures 1 to 3 shown, the connecting rod 206 is rotatably connected to the fixed rod 205. The connecting rod 206 is used to connect the fixed rod 205 and the backrest 101. A pair of fixing brackets 207 are installed on the support rod 202, and the fixing brackets 207 are used to support the backrest 101.

[0029] As Figure 1 shown, a pair of connecting blocks 208 are fixed on the backrest 101. The connecting blocks 208 are used to support the thin rods. A pair of thin rods are fixed on the connecting blocks 208. The thin rods are rotatably connected to the ends of the connecting rod 206 and the fixing bracket 207 that are far away from the support rod 202. The thin rods are used to support one end of the connecting rod 206 and the fixing bracket 207, and enable the connecting rod 206 and the fixing bracket 207 to rotate around the central axis of the thin rod.

[0030] As Figure 2 shown, a buffer spring 209 is installed between the support block 203 and the support rod 202. The buffer spring 209 is used to support the support block 203 and can buffer the pressure received on the support block 203.

[0031] As Figure 4 shown, the fixing mechanism 3 is installed on the fixing block 201. The fixing mechanism 3 includes a lifting block 301, and the lifting block 301 is used to support the bolt 302. The bolt 302 is fixed on the lifting block 301 and can be inserted into the fixing hole to fix the rotating wheel 303.

[0032] As Figure 4 shown, a rotating wheel 303 is installed on the support rod 202. The rotating wheel 303 can be fixed by the bolt 302, so that the support rod 202 can be fixed. A plurality of fixing holes corresponding to the bolt 302 are drilled in the rotating wheel 303, and the fixing holes are used to place the bolt 302.

[0033] As Figure 4 shown, a limiting rod 304 is fixed on the fixing block 201. The limiting rod 304 is used to support the lifting block 301 and can restrict the moving track of the lifting block 301. A baffle 305 is fixed at one end of the limiting rod 304. The baffle 305 can be supported on the side wall of the sliding cavity 306 to support the lifting block 301.

[0034] As Figures 1 to 4As shown, a sliding cavity 306 is formed inside the lifting block 301, and a baffle 305 is placed inside the sliding cavity 306. A return spring 307 is installed between the lifting block 301 and the fixed block 201. The return spring 307 is used to push the lifting block 301 to move, so as to be able to push the bolt 302 to move, enabling the bolt 302 to insert into the fixing hole to fix the rotating wheel 303.

[0035] During specific use, when the user leans on the backrest 101, the backrest 101 rotates around the fixed frame 207 under the support of the fixed frame 207, so as to be able to push the connecting rod 206, and the connecting rod 206 pushes the fixed rod 205, the slider 204 and the support block 203 to squeeze the buffer spring 209. The buffer spring 209 can buffer the pressure received by the support block 203, making the user feel more comfortable when leaning on the backrest 101.

[0036] Press the lifting block 301, and the lifting block 301 can drive the bolt 302 to move, so that the bolt 302 is pulled out from the fixing hole, making it difficult for the bolt 302 to fix the rotating wheel 303, and the lifting block 301 can squeeze the return spring 307.

[0037] Push the backrest 101 according to the needs, so that the support rod 202 rotates on the fixed block 201, so as to be able to drive the backrest 101 to be adjusted left and right, enabling the backrest 101 to better support the human back. After the adjustment is completed, release the lifting block 301, and the return spring 307 pushes the lifting block 301 to move under the action of elasticity, so that the lifting block 301 drives the bolt 302 to insert into the fixing hole to fix the rotating wheel 303, thereby being able to fix the support rod 202.

[0038] Compared with the prior art, the backrest support connecting piece of the present utility model can be adjusted left and right according to different sitting postures, enabling the seat backrest to better support the human body, making it difficult for the user to feel uncomfortable during use, and being able to make the seat backrest receive force more evenly, increasing the service life of the seat.

[0039] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
