Description

Technical Field

[0001] This application relates to the field of seating technology, and in particular to a support rod structure for a table and chair frame and a chair. Background Technology

[0002] Traditional chair backrest frames typically use several connection methods: welding or riveting, or plug-in joints with screws. However, these connection methods have some drawbacks. Welded or riveted connections are often impossible to disassemble or fold, resulting in high transportation and repair costs. While plug-in joints with screws allow for disassembly and folding, assembly and disassembly are cumbersome. This method is particularly troublesome for parts where connection strength requirements are not high, such as the backrest. Therefore, the purpose of this application is to address these issues.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] The technical solution adopted by this application to solve its technical problem is a support rod structure for a table and chair frame, including: a connecting pipe and a receiving pipe. One end of the connecting pipe is provided with a threaded post, and the other end is provided with a first insertion post. One end of the receiving pipe connected to the connecting pipe is provided with a threaded hole for connecting with the threaded post, and the other end is provided with a second insertion post. The first insertion post and the second insertion post are used to connect the table and chair frame, and the connection structure can be strengthened or the connection state can be unlocked by rotating the connecting pipe or the receiving pipe.

[0006] In some embodiments, a protective outer tube is provided around the periphery of the connecting pipe and the receiving pipe.

[0007] In some embodiments, the protective outer tube and the receiving tube or connecting tube are provided with slots for installing pins.

[0008] In some embodiments, the protective outer tube is provided with connecting portions at both ends, and the connecting portions are sleeved on the connecting tube and the receiving tube.

[0009] This application also provides a chair, including a seat frame and the aforementioned support rod structure, wherein the support frame is connected to the seat frame by screws, and the support rod structure is disposed above the seat frame.

[0010] In some embodiments, the seat frame is provided with slots that mate with the first and second plug-in posts.

[0011] The beneficial effects of this application are that the connecting pipe and the receiving pipe connected by threads can be connected and fixed by extending the overall length of either one by rotating, or the connecting pipe and the receiving pipe can be shortened by rotating to achieve the effect of quick disassembly.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0018] In the embodiments of this application, please refer to Figure 1-3As shown, this application provides a support rod structure for a table and chair frame, mainly including: a connecting pipe 1 and a receiving pipe 2. One end of the connecting pipe 1 is provided with a threaded post 11, and the other end is provided with a first insertion post 12. One end of the receiving pipe 2 connected to the connecting pipe 1 is provided with a threaded hole for connecting with the threaded post 11, and the other end is provided with a second insertion post 21. The first insertion post 12 and the second insertion post 21 are used to connect the table and chair frame, and the connection structure can be strengthened or the connection state can be unlocked by rotating the connecting pipe 1 or the receiving pipe 2.

[0019] Specifically, the threaded connection between the connecting pipe 1 and the receiving pipe 2 allows the overall length of the connecting pipe 1 and the receiving pipe 2 to be adjusted by rotation. The presence of the first insertion post 12 and the second insertion post 21 enables the connecting pipe 1 and the receiving pipe 2 to achieve a firm connection with the table and chair frame under basic fixing conditions, and unlocking and installation are very convenient.
