[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 A replaceable gas spring for assisting in the height adjustment of a school desk includes a desk panel 1 and a base 2. The base 2 has a gas spring body 3 that drives the desk panel 1 to rise and fall. The lower ends of both sides of the desk panel 1 have quick-release grooves 12, which are open, non-through grooves. The upper surface of the base 2 has a quick-release cylinder 22 with a threaded hole 221 at its upper end. The outer surface of the gas spring body 3 has external threads 31, and the lower end of the gas spring body 3 is threaded into the quick-release cylinder 22 through the external threads 31. Internally, the external thread 31 is adapted to the threaded hole 221. The upper end of the gas spring body 3 is inserted into the quick-release groove 12. The gas spring body 3 is screwed to the base 2. The lifting and lowering of the table 1 can be adjusted by the relative rotation between the gas spring body 3 and the base 2. In use, by connecting the lower end of the gas spring body 3 to the quick-release cylinder 22 of the base 2 and inserting the upper end into the quick-release groove 12 at the lower ends of both sides of the table 1, a stable connection between the gas spring body 3 and the table 1 can be achieved, thereby achieving the purpose of quick assembly and disassembly.

[0026] Furthermore, the bottom of the quick-release slot 12 is provided with a first magnetic surface 121, and the upper end of the gas spring body 3 is provided with a second magnetic surface 32. The first magnetic surface 121 and the second magnetic surface 32 attract each other. In use, the first magnetic surface 121 and the second magnetic surface 32 enhance the stability of the gas spring body 3 when connected to the table 1, reduce shaking during lifting and lowering, and also provide some convenience for disassembly. Since the attraction of the magnetic surface is relatively small, it will not cause too much obstruction to disassembly.

[0027] Furthermore, the bottom of the tabletop 1 is also provided with a drawer 11 for storing items. When in use, the drawer 11 can conveniently store students' school supplies, etc., which increases the functionality of the desk. Combined with the gas spring assisted lifting structure, it makes the desk more practical as a whole.

[0028] Furthermore, the base 2 includes a support plate 21 and a quick-release cylinder 22. The support plate 21 is welded and fixed to the base 2. When in use, the base 2 has a relatively solid structure, which can provide stable support for the entire gas spring body 3 and the table 1. At the same time, because the support plate 21 is welded and fixed to the base 2, the connection strength between the two is guaranteed, ensuring the stability of the desk during use.

[0029] Furthermore, the upper end of the gas spring body 3 is adapted to the quick-release slot 12. In use, the adapted design ensures that the gas spring body 3 can be smoothly inserted into the quick-release slot 12, and the two cooperate well during the lifting process without jamming or loosening, which further improves the smoothness and stability of the desk lifting.

[0030] Furthermore, four quick-release slots 12 are evenly distributed on the lower ends of both sides of the tabletop 1, located at the four corners of the tabletop 1 respectively. In use, this layout allows the gas spring body 3 to be evenly distributed under the tabletop 1, thereby making the tabletop 1 more evenly stressed during the lifting process, preventing the tabletop 1 from tilting or being damaged due to uneven stress, and improving the safety and stability of the desk.

[0031] Furthermore, the first magnetic surface 121 and the second magnetic surface 32 are magnetically compatible. When in use, magnetic compatibility means that the attraction between the two is appropriate. While ensuring a stable connection between the gas spring body 3 and the table 1, it will not be difficult to disassemble due to excessive magnetic force, nor will it fail to play a fixing role due to insufficient magnetic force, thus ensuring the convenience of the entire device in use and maintenance.

[0032] Furthermore, the gas spring body 3 is a controllable gas spring. In use, the controllable gas spring is a prior art in this field. Its working principle is to use an inert gas as an elastic medium and an elastic element that is sealed and lubricated with oil to transmit pressure. It controls the stroke by opening and closing the valve, so that the stroke can stop at any position. This gas spring has the advantages of adjustability, stability, smoothness and high load capacity. In this design, the controllable gas spring is used as the power source to assist in the lifting of the desk. Users can control the gas spring with remote control or other control devices according to actual needs to realize the lifting function of the desk 1 and can accurately adjust the lifting position, which improves the convenience and comfort of using the desk.

[0033] Working Principle: This utility model discloses an easily replaceable gas spring for assisting in the height adjustment of a school desk. During installation, the external thread 31 at the lower end of the gas spring body 3 is first inserted into the quick-release cylinder 22 on the base 2. The external thread 31 matches the threaded hole 221 at the upper end of the quick-release cylinder 22, thereby achieving a fixed connection between the gas spring body 3 and the base 2. Four quick-release slots 12 are evenly distributed on the lower ends of both sides of the desk 1, located at the four corners of the desk 1. The upper end of the gas spring body 3 is inserted into the corresponding quick-release slot 12. The bottom of the quick-release slot 12 is provided with a first magnetic surface 121, and the upper end of the gas spring body 3 is provided with a second magnetic surface 32. The first magnetic surface 121 and the second magnetic surface 32 attract each other, enhancing the stability of the connection between the gas spring body 3 and the desk 1. When it is necessary to adjust the height of the desk, the height of the desk 1 is achieved by controlling the extension and retraction of the controllable gas spring body 3. The controllable gas spring body 3 uses inert gas as the elastic medium, is sealed and lubricated with oil and transmits pressure, and is controlled by the opening and closing of a valve. The travel distance allows the gas spring to stop at any position, offering advantages such as adjustability, stability, smoothness, and high load capacity. Users can control the device via remote control to adjust the height of the tabletop 1, precisely adjusting the lifting position and enhancing the convenience and comfort of the desk. When the gas spring body 3 is damaged and requires repair, the threaded connection and quick-release groove 12 design allow for quick removal of the gas spring body 3 from the base 2 and tabletop 1, facilitating repair or replacement and improving the desk's ease of use and efficiency. Simultaneously, the first magnetic surface 121 and the second magnetic surface 32 of the magnetic adapter ensure stable connection and easy disassembly, further enhancing the convenience of the entire device during use and maintenance. During normal use, the bottom of the tabletop 1 also features a drawer 11 for storing items, allowing students to conveniently store school supplies, increasing the desk's functionality. Combined with the gas spring-assisted lifting structure, this makes the desk more practical overall.
