Description

Technical Field

[0001] This utility model relates to the field of chair design technology, and in particular to a height-adjustable chair. Background Technology

[0002] Chairs are a common type of seating in people's daily lives, and they come in a variety of shapes and sizes. In office settings, height-adjustable chairs are often arranged to meet the needs of users of different heights.

[0003] A typical adjustable chair mainly consists of a seat cushion, a gas spring, and a support base. The gas spring connects the seat cushion and the support base and primarily functions to raise and lower the chair. The connection between the seat cushion and the gas spring is relatively complex. Currently, technicians typically need to install a support board at the bottom of the seat cushion for support, and then add a metal component at the bottom of the support board to connect the seat cushion to the gas spring.

[0004] As can be seen from the above structure, the connection between the seat cushion and the gas spring is quite complex, with many parts, which increases production costs and assembly difficulty, seriously affecting the production efficiency of the adjustable chair.

[0005] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Utility Model Content

[0030] This utility model discloses a lifting chair to solve the technical problem that the existing lifting chairs have complex structures, resulting in low production efficiency.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 4 The present invention provides a height-adjustable chair, including a seat cushion 1, a gas spring 3 and a support base 4;

[0033] The bottom of the cushion 1 is connected to the mounting base 2, the first end of the gas spring 3 is connected to the mounting base 2, and the second end of the gas spring 3 is connected to the support base 4.

[0034] In this embodiment of the adjustable chair, the seat cushion 1 is connected to the gas spring 3 only through the mounting base 2, thereby effectively reducing the assembly complexity between the seat cushion 1 and the gas spring 3. This helps to save parts and reduce production costs, while also making it easier for operators to assemble and effectively improving production efficiency.

[0035] Furthermore, in this embodiment, the mounting base 2 is specifically formed of plastic by injection molding. In addition, in this embodiment, the cushion 1 specifically includes an outer layer and a flexible layer.

[0036] The outer layer is sleeved on the top of the mounting base 2, and the flexible layer is filled between the outer layer and the mounting base 2.

[0037] It should be noted that, through the above design, the seat cushion 1 is directly formed on the top of the mounting base 2, which can effectively simplify the assembly structure and help improve production efficiency.

[0038] Specifically, the outer surface can be selected as a leather layer, a fabric layer, or other material layer. This embodiment does not limit this, and designers can make a reasonable selection according to the actual situation.

[0039] The aforementioned flexible layer can be selected as a sponge layer or other flexible layer. This embodiment does not impose any restrictions on this, and designers can make reasonable selections according to actual conditions.

[0040] Furthermore, in this embodiment, the bottom center of the mounting base 2 is recessed inward to form a first mounting groove 201;

[0041] The first end of the air pressure rod 3 is fixed in the first mounting groove 201.

[0042] It should be noted that, through the above design, the first end of the pneumatic rod 3 can be embedded inside the mounting base 2, making the connection between the pneumatic rod 3 and the mounting base 2 more compact.

[0043] Furthermore, the support base 4 in this embodiment includes a fixing part and a plurality of support feet 401;

[0044] The second end of the pneumatic rod 3 is connected to the fixing part, and a plurality of the support feet 401 are arranged at intervals along the circumference of the fixing part.

[0045] It should be noted that, through the above design, multiple support feet 401 work together to support the seat cushion 1, thereby effectively improving the stability of the adjustable chair.

[0046] Furthermore, in this embodiment, the fixing part is recessed inward to form a second mounting groove 403;

[0047] The second end of the pneumatic rod 3 is fixed in the second mounting groove 403.

[0048] It should be noted that, through the above design, the second end of the pneumatic rod 3 can be embedded inside the fixing part, making the connection between the pneumatic rod 3 and the fixing part more compact.

[0049] It should also be noted that the second end of the pneumatic rod 3 in this embodiment is the control valve contact of the pneumatic rod 3.

[0050] Furthermore, the pneumatic rod 3 in this embodiment is existing technology. Its specific working principle is as follows: by triggering the control valve contact, the control valve is opened, and the nitrogen pressure inside the pneumatic rod 3 circulates from the lower end of the piston to the upper end, thus driving the seat cushion 1 to rise. When the control valve is closed, the piston position will remain at the position just adjusted, that is, the seat cushion 1 will maintain the previously set height. Therefore, when it is necessary to adjust the height of the seat cushion 1, the control valve contact can be triggered to open the control valve. In this embodiment, the user can control the control valve contact through the operating lever or foot pedal on the pneumatic rod 3. This is existing technology and will not be described in detail here.

[0051] Furthermore, in this embodiment, the end of the support foot 401 away from the fixed part is connected to a universal caster wheel 402.

[0052] It should be noted that the above design makes it easier for users to move the height-adjustable chair, making it more convenient for users to use.

[0053] In addition, the aforementioned omnidirectional caster 402 may be equipped with a braking function to prevent the chair from shifting when the user sits on it.

[0054] The above provides a detailed description of the adjustable chair provided by this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
