Technical Field

[0001] This invention relates to the field of office chair technology, and more specifically to a single-arm rotating simple mounting chassis for an office chair. Background Technology

[0002] Office chairs are frequently used seating in daily work, and their quality directly impacts user comfort. The chassis is a crucial component, determining the chair's stability. However, current chassis assembly methods primarily rely on mechanical equipment, using mainly iron as the structural material. While this traditional method offers high production efficiency when sufficient production equipment is available, it demands sophisticated production facilities, involves a complex assembly process, and is difficult for ordinary users to complete independently, thus limiting the product's ease of installation and flexibility of use. Therefore, to overcome the shortcomings of existing technology, it is necessary to improve it. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a simple, easy-to-install single-arm rotating mounting base for office chairs.

[0004] This invention is achieved through the following technical solution:

[0005] A single-arm rotating easy-installation chassis for an office chair includes a seat frame, a chassis main compartment, and a handle. The seat frame is provided with a chassis mounting groove for mounting the chassis main compartment. A positioning connecting shaft that abuts against the chassis main compartment is installed on the rear side of the seat frame by a first screw. The handle is installed in the chassis main compartment by a second screw.

[0006] Furthermore, it also includes a spring, and the main chassis compartment is provided with a spring mounting slot for mounting the spring.

[0007] Furthermore, the top of the main chassis compartment is provided with a positioning mounting groove, and the top of the chassis mounting groove is provided with a positioning mounting block corresponding to the positioning mounting groove.

[0008] Furthermore, the bottom of the seat frame is provided with a first positioning mounting groove for positioning and mounting the positioning connecting shaft.

[0009] Furthermore, the bottom of the main chassis compartment is provided with a second positioning mounting groove for positioning and mounting the positioning connecting shaft.

[0010] Furthermore, the top of the main chassis compartment is provided with a hinge slot for mounting the handle.

[0011] Furthermore, armrests are installed on both the left and right sides of the seat frame using armrest screws.

[0012] Furthermore, the bottom of the armrest is provided with a connecting part, and the seat frame is provided with a connecting groove corresponding to the connecting part.

[0013] Furthermore, a back frame is installed on the rear side of the armrest via back frame screws.

[0014] Furthermore, the back of the armrest is provided with a back frame connecting part for mounting the back frame, and the back frame is provided with a plug groove for the back frame connecting part to be inserted.

[0015] Compared to existing technologies, this invention features a chassis mounting slot in the frame for mounting the main chassis compartment. A positioning connecting shaft that abuts against the main chassis compartment is mounted on the rear side of the frame via a first screw. The handle is mounted to the main chassis compartment via a second screw. The core technology is installation using the pressure generated by screw tightening, which simplifies the complex installation process of traditional chassis that relies on mechanical equipment. Users can complete the chassis installation independently without the need for professional equipment, simply through manual operation, greatly reducing the installation threshold and improving the product's ease of use and user experience.
