Description

Technical Field

[0001] This utility model relates to the field of fiberglass chair technology, specifically to a quick-assembly structure for a fiberglass chair body with a rapidly replaceable seat. Background Technology

[0002] In some public places, such as stadiums or school tiered classrooms, automatic flip-up chairs are often used. The flip-up is usually achieved by torsion springs or gravity. These chairs are often made of fiberglass seats, which are made of glass fiber reinforced plastic as the main material. They are produced by molding or hand-forming processes and have the characteristics of being lightweight, high-strength, weather-resistant and easy to maintain. They are suitable for home, office and public spaces.

[0003] If this type of chair uses a torsion spring reset mechanism, the torsion spring will fatigue and lose elasticity after prolonged use, resulting in weak reset capability. If gravity is used, the friction of the pivot shaft will prevent it from resetting. Furthermore, the seat is bolted in place, making disassembly and assembly cumbersome and hindering quick seat replacement. To address these issues, this invention provides a quick-installation fiberglass chair body structure for rapid seat replacement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-installation structure for a fiberglass chair body with a rapidly replaceable seat surface. This solves the problems of traditional chair reset methods, where torsion springs fatigue and weaken after prolonged use, resulting in weak reset, and gravity-based reset due to friction on the pivot shaft. Furthermore, the bolt-fixed seat surface makes disassembly and assembly cumbersome, hindering quick seat replacement and installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly structure for a fiberglass chair body with a rapidly replaceable seat surface, comprising a fiberglass quick-assembly assembly. The assembly includes a snap-fit ​​plate for snapping the fiberglass seat surface. A fixed elongated block is movably snapped onto the front end of the snap-fit ​​plate to secure the fiberglass seat surface within the snap-fit ​​plate. A counterweight is installed at the bottom of the snap-fit ​​plate to increase its weight. A connecting support structure is provided outside the fiberglass quick-assembly assembly, and the assembly is rotatably connected to this structure.

[0006] Preferably, the inner side of the snap-fit ​​plate is provided with a snap-fit ​​groove, which is used to limit the fiberglass chair surface. The front side of the snap-fit ​​groove is provided with a fixing through hole, and a fixing pin is provided in the fixing block. The fixing pin is movably snapped into the fixing through hole.

[0007] Preferably, the fixed long block is further provided with a sliding groove and a side through hole. The sliding groove and the side through hole are both opened on the left and right sides of the fixed long block. The side through hole is opened on the outside of the sliding groove, and the fixed pin is slidably connected in the side through hole.

[0008] Preferably, the fixed long block is further provided with a slider and a spring. The slider is fixedly connected to the inner side of the fixed pin post and slidably connected in the sliding groove. One end of the spring is fixedly connected in the sliding groove and the other end of the spring is fixedly connected to the slider. The slider is used to be moved and drive the fixed pin post to move, and the spring is used to drive the slider to reset.

[0009] Preferably, the connecting support structure includes supporting side columns, which are provided in two sets, left and right. A rotating groove is opened in the supporting side column, and a rotating shaft is fixedly connected to the outside of the snap-fit ​​plate. The rotating shaft is rotatably connected in the rotating groove.

[0010] Preferably, the connecting support structure further includes a backrest connecting plate, a bottom connecting plate, and a seat limiting plate. The backrest connecting plate is fixedly connected to the top of the supporting side column and is used to fix it to the backrest. The bottom connecting plate is fixedly connected to the bottom of the supporting side column and is used to fix it to the seat base. The seat limiting plate is fixedly connected between the two sets of supporting side columns and is used to support the fiberglass quick-assembly assembly and the fiberglass seat.

[0011] Its beneficial effects are as follows:

[0012] This quick-installation structure for a fiberglass chair body with a rapidly replaceable seat surface makes seat replacement faster and more convenient by incorporating quick-installation and disassembly components. Furthermore, the addition of counterweights allows the seat surface to flip quickly under its own weight, resulting in a better flipping effect. Attached Figure Description
