[0002] Lightweight folding chairs are simple in structure, easy to carry and store. Their biggest feature is the ability to quickly fold or unfold the chair, adapting to various usage scenarios. These chairs are typically made of lightweight materials such as aluminum alloy, plastic, or high-strength fabric, offering advantages such as light weight, high strength, and durability. They are widely used in outdoor leisure, travel and camping, office meetings, and as temporary seating in the home. The rationally designed folding structure significantly saves space when not in use, improving the convenience of storage and transportation, making it a seating product that combines practicality and portability.

[0003] In today's society, people are paying more and more attention to outdoor sports. When engaging in outdoor activities, people often carry folding chairs for convenient rest anytime, anywhere. However, existing folding chairs use screws to fix the support rods and crossbars, as well as the legs and crossbars. This connection method makes assembly and disassembly quite cumbersome. Each component needs to be secured with screws, and after use, each screw must be removed, and the legs, crossbars, and support rods must be disassembled one by one. This cumbersome process consumes a lot of time and causes inconvenience to users. Furthermore, because the bolts protrude, they are prone to breakage during transport due to collisions, increasing the inconvenience of carrying them and potentially causing accidental injury to users. In addition, they take up a lot of space, which is not conducive to the portability requirements of outdoor travel.

[0004] Based on this, we propose a lightweight folding chair to solve the problems mentioned above. Utility Model Content

One end of each of the four sets of support rods 6 is connected to a first embedded clip 9. A second embedded clip 10 is provided at the end of the support rod 6 away from the first embedded clip 9 and at the end of the support leg 5. A connecting hole 11 is also provided through the middle of the second embedded clip 10. This lightweight folding chair is connected by the seat fabric 1, crossbar 7, legs 5, support rods 6, and elastic tensioning member. The combination of components 8 allows for the rapid construction of a complete folding chair frame without any tools or complex operations, significantly saving assembly time. Furthermore, the folded seat fabric 1 and folding support components 2 occupy minimal space, facilitating portability and long-distance transport, effectively improving the efficiency and convenience of the folding chair. A storage cavity 12 is provided in the middle of the crossbar 7, and embedded slots 13 are provided at each of the four corners on both sides of the crossbar 7. These embedded slots 13 are used for the snap-fit ​​connection between the crossbar 7 and the legs 5 and support rods 6. The embedded slots 13 are structurally matched with the first embedded clip head 9, and the snap-fit ​​between the embedded slots 13 and the first embedded clip head 9 allows for the rapid assembly of four sets of support rods 6 and four sets of support legs 5 onto the upper and lower sides of the crossbar 7.

[0028] The elastic tensioning component 8 includes two sets of connecting base blocks 14, which are structurally matched with the receiving cavity 12.

[0029] Working Principle: The lightweight folding chair designed in this scheme mainly consists of a seat fabric 1, a crossbar 7, legs 5, support rods 6, and an elastic tensioning component 8. The crossbar 7 has multiple embedded slots 13 distributed on its upper and lower sides. First elastic straps 15, installed on both sides of the connecting base block 14, pass through these embedded slots 13 from the inside of the crossbar 7 and connect to the connecting holes 11 at one end of the support rods 6 and legs 5. When assembling the folding chair, the user only needs to hold the crossbar 7 with one hand and pull the four sets of legs 5 and four sets of support rods 6 in sequence with the other hand. Under the elastic action of the elastic tensioning component 8, the second elastic straps 15 installed on one end of the legs 5 and support rods 6... The embedded clip 10 is pulled and snapped into the embedded slot 13 on the surface of the crossbar 7, forming a stable triangular support structure on the upper and lower sides of the crossbar 7. During this process, the elastic tensioner 8 provides the necessary tension to ensure that the four sets of support legs 5 and the four sets of support rods 6 can be tightly connected to the crossbar 7. Through the structural design of the snap-fit ​​between the sleeve 18 and the first embedded clip 9, the seat cloth 1 used for supporting the body scale can also be assembled at one end of the four sets of support rods 6. This process can quickly build a complete folding chair frame without any tools or complicated operations, greatly saving assembly time.

[0030] The lightweight folding chair designed in this scheme allows users to easily remove it from the recessed slots 13 of the crossbar 7 when they need to leave after resting. By holding the crossbar 7 with one hand and pulling the four sets of legs 5 and four sets of support rods 6 in sequence with the other, the four sets of legs 5 can be pulled out from the inside of the mounting bracket 18 by pulling the four corners of the seat fabric 1. The seat fabric 1, which is used to support the body scale, can be detached from one end of the four sets of support rods 6. The detached seat fabric 1 and folding support components 2 are easy for users to store and fold. The folded seat fabric 1 and folding support components 2 occupy very little space, making them easy to carry and transport over long distances, effectively improving the efficiency and convenience of the folding chair.
