Writing chairs typically come with a writing table, which is usually secured to the seat with screws and nuts. In practice, if users need to temporarily remove the table to make room or for storage, tools are often required for disassembly, which is inefficient and carries the risk of losing small parts.

[0003] Based on this, this utility model designs a quick-release folding writing chair to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-release folding writing chair to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release folding writing chair, comprising: a seat; a sliding sleeve and a socket are respectively fixed to the bottom of the seat, an arm tube is inserted into the sliding opening of the sliding sleeve, a writing table is fixed to one end of the arm tube, and the other end is inserted into the socket opening;

[0006] A mounting plate is fixedly connected to the bottom of the chair seat. A rod is inserted into the outer wall of the mounting plate. A handle is fixedly connected to one end of the rod. A spring is fixedly installed between one end of the handle and the mounting plate. A first insertion hole and a second insertion hole are opened on the outer wall of the arm tube. The end of the rod away from the handle is inserted into the first insertion hole of the arm tube.

[0007] Preferably, the spring between the grip and the mounting plate is sleeved on the outer wall of the insertion rod.

[0008] Preferably, the first and second insertion holes of the arm tube are arranged in a cross shape.

[0009] Preferably, a chair back is fixedly provided at one end of the chair seat.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: no additional tools are required, and the writing desk can be quickly assembled and disassembled by the cooperation of the first insertion hole of the insertion rod and the arm tube, which greatly improves convenience and efficiency. Moreover, when the writing desk is folded and stored, the writing desk is more stable after being folded and stored by switching the first insertion hole to the second insertion hole.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a quick-release folding writing chair, including: a seat 1; a sliding sleeve 3 and a socket 4 are fixed to the bottom of the seat 1 respectively, an arm tube 5 is inserted into the sliding opening of the sliding sleeve 3, a writing table 6 is fixed to one end of the arm tube 5, and the other end is inserted into the socket 4.

[0022] A mounting plate 9 is fixedly connected to the bottom of the seat 1. A rod 10 is inserted into the outer wall of the mounting plate 9. A handle 11 is fixedly connected to one end of the rod 10. A spring 12 is fixedly installed between one end of the handle 11 and the mounting plate 9. A first insertion hole 7 and a second insertion hole 8 are opened on the outer wall of the arm tube 5. The end of the rod 10 away from the handle 11 is inserted into the first insertion hole 7 of the arm tube 5.

[0023] The writing desk 6 forms a double-point support structure through the sliding sleeve 3, the arm tube 5, and the socket 4. When the writing desk 6 is installed, the insertion rod 10 is inserted into the insertion hole on the arm tube 5 with the help of the spring 12 to achieve the limiting and fixing of the arm tube 5. The user can pull out the insertion rod 10 by pulling the spring 12 through the handle 11, and quickly disassemble the writing desk 6. The operation is relatively convenient. The arm tube 5 can rotate after the insertion rod 10 is removed. With the interchange of the first insertion hole 7 and the second insertion hole 8, the writing desk 6 can be stably folded and stored.

[0024] In a further preferred embodiment, the spring 12 between the grip 11 and the mounting plate 9 is sleeved on the outer wall of the insertion rod 10;

[0025] The spring 12 is not hidden inside, but is exposed and sleeved on the outer wall of the plug rod 10. In medium-frequency application environments such as offices and furniture, the spring 12 is made of 65Mn material and has a cycle life of more than 100,000 cycles. When the spring 12 retracts between the handle 11 and the mounting plate 9, it can push the plug rod 10 into or out of the aligned first plug hole 7 or second plug hole 8.

[0026] In a further preferred embodiment, the first insertion hole 7 and the second insertion hole 8 of the arm tube 5 are arranged in a cross shape and staggered.

[0027] The first socket 7 and the second socket 8 are arranged in a cross pattern, that is, they are distributed along the horizontal and vertical directions on the arm tube 5. The plug rod 10 can be inserted into the sockets in both directions to achieve multi-angle positioning.

[0028] A further preferred embodiment has a chair back 2 fixedly installed at one end of the seat 1;

[0029] A backrest structure 2 is added to the rear of the seat 1 to support the user's back and distribute pressure.

[0030] One specific application of this embodiment is as follows: During initial installation, the handle 11 is used to pull the insert rod 10 away, and then the arm tube 5 on one side of the writing table 6 is inserted into the sliding sleeve 3 of the chair seat 1. The other end is aligned with the socket 4 at the bottom of the chair seat 1 and inserted to form a basic connection structure. Then, the handle 11 is released, and the tension of the spring 12 is used to insert the front end of the insert rod 10 into the first insertion hole 7 on the outer wall of the arm tube 5, which stabilizes and fixes the arm tube 5. The person can then sit on the chair seat 1 and write on the writing table 6. When the writing table 6 needs to be removed, the handle 11 is tightened again to stretch the spring 12 and pull the insert rod 10 out of the first insertion hole 7. The arm tube 5 can then be pulled out from between the sliding sleeve 3 and the socket 4, realizing the quick separation of the writing table 6.

[0031] When the writing desk 6 is folded and stored, the insertion rod 10 is moved away from the first insertion hole 7. Then, the arm tube 5 between the sliding sleeve 3 and the socket 4 can be rotated to move the writing desk 6 toward the chair back 2. After folding it close to the chair back 2, the cross-shaped second insertion holes 8 will align with the insertion rod 10. Then, inserting the insertion rod 10 into the second insertion hole 8 will stabilize the folded writing desk 6 and prevent it from coming loose.
