Description

Technical Field

[0001] This utility model relates to the field of office chair chassis technology, and in particular to a novel fiberglass office chair chassis. Background Technology

[0002] A fiberglass base for office chairs is a support device used for tilting and adjusting office chairs. The main elasticity methods for existing office chair bases include spring pressing, torsion spring torque, torsion bar torque, and fiberglass sheet pressing. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of fiberglass bases for office chairs.

[0003] Existing office chair chassis have certain drawbacks in use. The fiberglass sheet press-type chassis has not been updated for many years, and the operation is relatively troublesome, which brings certain adverse effects to the actual use process. Therefore, we propose a new type of fiberglass chassis for office chairs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel fiberglass chassis for office chairs. When tilting, the back support moves, and the apex on the back support rotates around the pivot point. As the apex pushes upward, the middle part of the fiberglass sheet deforms under the action of the apex, providing elasticity for tilting, which can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel fiberglass chassis for an office chair, comprising a chassis body, wherein a back support, a fiberglass sheet, and an elastic adjustment component are disposed inside the chassis body. The back support is located at the front end of the fiberglass sheet, the elastic adjustment component is located at the rear end of the fiberglass sheet, a rear positioning point is installed at the front end of the fiberglass sheet, a front positioning point is installed at the rear end of the fiberglass sheet on the elastic adjustment component, a vertex is provided at the position where the bottom end of the back support connects to the fiberglass sheet, a turning point is provided in the middle of the back support, and an upper support is provided at the upper end of the chassis body.

[0006] Preferably, a connector is provided between the back support and the upper support, and a limiter is provided between the chassis body and the upper support.

[0007] Preferably, the back support and the upper support are engaged by a connector, and the upper support and the chassis body are limited by a limiter.

[0008] Preferably, the back support is fixed to the chassis body by a pivot point, the back support rotates clockwise around the pivot point, the two ends of the fiberglass sheet are fixed to the rear positioning point and the front positioning point respectively, and the middle of the fiberglass sheet contacts the vertex on the back support.

[0009] Compared with the prior art, this utility model provides a novel fiberglass chassis for office chairs, which has the following beneficial effects: When tilting, the back support moves, and the apex on the back support rotates around the pivot point. The apex pushes upward, and at the same time as the apex pushes upward, the middle part of the fiberglass sheet deforms under the action of the apex, providing elasticity for tilting. The back support is fixed to the chassis body through the pivot point and rotates clockwise around the pivot point. The two ends of the fiberglass sheet are fixed to the rear positioning point and the front positioning point, respectively, and the middle of the fiberglass sheet contacts the apex on the back support. The entire fiberglass chassis for office chairs has a simple structure, is easy to operate, and has a better effect than the traditional method. Attached Figure Description

[0015] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0016] like Figure 1-4 As shown, a novel fiberglass chassis for an office chair includes a chassis body 1. Inside the chassis body 1, there is a back support 2, a fiberglass sheet 3, and an elastic adjustment component 5. The back support 2 is located at the front end of the fiberglass sheet 3, and the elastic adjustment component 5 is located at the rear end of the fiberglass sheet 3. A rear positioning point 4 is installed at the front end of the fiberglass sheet 3, and a front positioning point 6 is installed at the rear end of the fiberglass sheet 3 on the elastic adjustment component 5. A vertex 8 is provided at the bottom end of the back support 2 where it connects to the fiberglass sheet 3. A pivot point 7 is provided in the middle of the back support 2. An upper support 9 is provided at the upper end of the chassis body 1. When tilting, the back support moves, and the vertex on the back support rotates around the pivot point. The vertex pushes upward, and at the same time as the vertex pushes upward, the middle part of the fiberglass sheet deforms under the action of the vertex, providing elasticity for tilting.

[0017] Furthermore, a connector 10 is provided between the back support 2 and the upper support 9, and a limiter 11 is provided between the chassis body 1 and the upper support 9.

[0018] Furthermore, the back support 2 and the upper support 9 are engaged by a connector 10, and the upper support 9 and the chassis body 1 are limited by a limiter 11.

[0019] Furthermore, the back support 2 is fixed to the chassis body 1 via the pivot point 7. The back support 2 rotates clockwise around the pivot point 7. The two ends of the fiberglass sheet 3 are fixed to the rear positioning point 4 and the front positioning point 6, respectively. The middle of the fiberglass sheet 3 contacts the vertex 8 on the back support 2.

[0020] Working Principle: This utility model includes a chassis body 1, a back support 2, a fiberglass sheet 3, a rear positioning point 4, an elastic adjustment component 5, a front positioning point 6, a pivot point 7, a apex 8, an upper support 9, a connector 10, and a limiter 11. The chassis body 1 connects the various components. The back support 2 connects to the chassis body 1 and is also the main component for pressing the fiberglass sheet 3, which provides elasticity. The rear positioning point 4 is fixed to the chassis body 1, serving to fix the fiberglass sheet 3. The back support is fixed to the chassis body via the pivot point and rotates clockwise around the pivot point. The two ends of the fiberglass sheet are fixed to the rear and front positioning points respectively, and the middle of the fiberglass sheet contacts the apex on the back support. When tilting, the back support moves, and the apex on the back support rotates around the pivot point, pushing upwards. As the apex pushes upwards, the middle part of the fiberglass sheet deforms under the action of the apex, providing elasticity for tilting. The above shows and describes the basic principle, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
