[0023] 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.

[0024] Reference Figure 1 - Figure 3This utility model provides an embodiment of a high-strength and durable office desk support steel frame, comprising two sets of support legs 1 and a desktop 19. The support legs 1 are connected to a main horizontal plate 3 via a lifting assembly. A slot 4 is provided at the top center of each main horizontal plate 3. Connecting plates 22 are fixedly connected to the left and right ends of opposite sides of the main horizontal plate 3. Folding plates 1 and 2 are rotatably connected to the inner walls of opposite sides of the connecting plates 22, respectively. Folding plates 1 and 2 are connected by hinges. Slide plates 7 are slidably connected to the inner walls of both folding plates 1 and 2. The inner walls of the front and rear ends of the slide plates 7 are provided with... Bolt 8, fixing blocks 11 are fixedly connected to the opposite side of the support leg 1, folding horizontal plates 12 are rotatably connected to the inner wall of the opposite side of the fixing blocks 11, connecting blocks 13 are rotatably connected to the opposite end of the folding horizontal plates 12, pin plates 21 are fixed to the front and rear sides of the bottom end of the tabletop 19, fixing pins 20 are fixedly connected to the four corners of the bottom end of the tabletop 19, positioning holes 10 are opened on the left and right sides of the top of the main horizontal plate 3 corresponding to the bottom end of the fixing pins 20, the size of the positioning holes 10 is adapted to the fixing pins 20, and through holes 9 are opened on the inner wall of the opposite side of the sliding rod 2, the size of the through holes 9 is adapted to the insertion rod 15.

[0025] Specifically, the connection via the lifting assembly means that the main horizontal plate 3 can move up and down under the action of the lifting assembly, thereby adjusting the height of the desktop 19 to meet the height needs of different users in different scenarios. The main horizontal plate 3 is fixedly connected to connecting plates 22 on opposite sides. The inner walls of the connecting plates 22 are respectively rotatably connected to folding plates 5 and 6, which are connected by hinges. This allows folding plates 5 and 6 to rotate around their connection point with the connecting plate 22, and also to rotate relative to each other. The rotatable design of folding plates 5 and 6 allows them to be unfolded when needed, increasing the support area of ​​the desktop 19 and improving support stability; when not needed, they can be folded up to reduce space occupation and facilitate storage and transportation. The inner walls of folding plates 5 and 6 are slidably connected to the slide plate 7, and bolts 8 are provided on the inner walls of the front and rear ends of the slide plate 7. The skateboard 7 can slide inside the folding board. The bolt 8 is used to fix the position of the skateboard 7 inside the folding board. The support leg 1 is fixedly connected to the fixing block 11 on one side. The inner wall of the fixing block 11 is rotatably connected to the folding horizontal plate 12. The folding horizontal plate 12 is rotatably connected to the connecting block 13 on one side. The folding horizontal plate 12 can rotate around the connection point with the fixing block 11 and is connected to the folding horizontal plate 12 on the other side through the connecting block 13. The rotatable connection design of the folding horizontal plate 12 can distribute the pressure to the support leg 1 when the tabletop 19 bears the weight, which enhances the connection strength between the support legs 1 and improves the stability and durability of the entire support steel frame.

[0026] The fixing pins 20 at the four corners of the bottom of the desktop 19 are adapted to the positioning holes 10 on the left and right sides of the top of the main horizontal plate 3, realizing the connection between the desktop 19 and the main horizontal plate 3. At the same time, the front and rear sides of the bottom of the desktop 19 are fixed with pin plates 21. The document does not mention the connection of the pin plates 21 with other components. The inner wall of the opposite side of the sliding rod 2 has a through hole 9. The size of the through hole 9 is adapted to the insertion rod 15. The insertion rod 15 can be inserted into the through hole 9. Combined with the lifting assembly, it may be used to fix the position of the sliding rod 2.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The lifting assembly includes a sliding rod 2 slidably connected to the inner wall of the support leg 1. The bottom end of the main horizontal plate 3 is fixedly connected to the top end of the sliding rod 2. An installation block 14 is fixedly connected to the opposite side of the support leg 1. Insert rods 15 are slidably connected to the inner wall of the installation block 14. Springs 18 are provided on the inner wall of the installation block 14. A handle 16 is fixedly connected to the opposite end of the insert rod 15. A sliding plate 17 is fixedly connected to the outer wall of the insert rod 15. The outer wall of the sliding plate 17 is slidably connected to the inner wall of the installation block 14. One end of the spring 18 is connected to the inner wall of the installation block 14, and the other end of the spring 18 is connected to the outer wall of the sliding plate 17.

[0028] Specifically, the sliding rod 2 is slidably connected to the inner wall of the support leg 1. This means that the sliding rod 2 can slide up and down along a certain trajectory within the internal space of the support leg 1, providing the basis for the height adjustment function of the desk desktop 19. When the height of the desktop 19 needs to be adjusted, the sliding rod 2 can move within the support leg 1, thereby changing the height of the desktop 19 connected to it to meet the personalized needs of different users for the height of the desktop 19. The bottom end of the main horizontal plate 3 is fixedly connected to the top end of the sliding rod 2. This fixed connection method makes the main horizontal plate 3 and the sliding rod 2 form a relatively stable overall structure.

[0029] Mounting block 14 is fixedly connected to the opposite side of support leg 1. This ensures a relatively fixed positional relationship between mounting block 14 and support leg 1, providing a mounting base and support structure for components such as insert rod 15 and spring 18. It ensures that these components can be stably mounted on support leg 1 and maintain their relative position during operation. Insert rod 15 is slidably connected to the inner wall of mounting block 14. Insert rod 15 can slide within the space defined by mounting block 14, and the sliding of insert rod 15 controls the position of sliding rod 2. When insert rod 15 is inserted into the corresponding hole on sliding rod 2, the position of sliding rod 2 is fixed, thereby locking the height of desktop 19. When insert rod 15 is pulled out of the hole, sliding rod 2 can slide freely to adjust the height of desktop 19. Handle 16 is fixedly connected to the opposite end of insert rod 15. This connection method makes handle 16 and insert rod 15 a single unit, providing convenience for user operation of insert rod 15. Users can control the sliding of the insertion rod 15 within the mounting block 14 by pulling or pushing the handle 16, thereby adjusting and locking the height of the desktop 19.

[0030] A sliding plate 17 is fixedly connected to the outer wall of the insertion rod 15. The insertion rod 15 and the sliding plate 17 move synchronously, with the sliding plate 17 assisting in the stable sliding of the insertion rod 15. It increases the contact area between the insertion rod 15 and the inner wall of the mounting block 14, reducing the shaking and offset of the insertion rod 15 during sliding, making the sliding of the insertion rod 15 more stable and smooth. The outer wall of the sliding plate 17 is slidably connected to the inner wall of the mounting block 14. This ensures that the sliding plate 17 can slide freely within the mounting block 14, further ensuring the stability of the sliding trajectory of the insertion rod 15 within the mounting block 14, preventing the insertion rod 15 from tilting or jamming during sliding, and improving the reliability and stability of the entire lifting assembly.

[0031] One end of the spring 18 is connected to the inner wall of the mounting block 14, and the other end is connected to the outer wall of the sliding plate 17. The spring 18 serves as an elastic restoring mechanism. When the user pulls the handle 16 to pull the insertion rod 15 out of the hole in the sliding rod 2, the spring 18 is compressed. When the user releases the handle 16, the elastic restoring force of the spring 18 pushes the sliding plate 17, thereby causing the insertion rod 15 to be inserted into the hole in the sliding rod 2, achieving automatic locking of the height of the desktop 19, which improves the convenience and stability of operation.

[0032] Working principle: When the user pulls handle 16, the insertion rod 15 slides within the mounting block 14. Simultaneously, the sliding plate 17 moves and compresses the spring 18, causing the insertion rod 15 to disengage from the through hole 9 on the inner wall of the sliding rod 2, releasing the lock on the sliding rod 2. The sliding rod 2 can then slide freely up and down on the inner wall of the support leg 1, causing the main horizontal plate 3 and the desktop 19, which are fixedly connected at the top, to rise and fall synchronously to the desired height. Releasing handle 16 causes the spring 18 to push the sliding plate 17 and insertion rod 15 back to their original positions due to its elastic restoring force. The insertion rod 15 then inserts into the through hole 9 at the corresponding height of the sliding rod 2, locking the position of the sliding rod 2 and fixing the height of the desktop 19. The fixing pins 20 at the four corners of the bottom of the desktop 19 are then inserted... The positioning hole 10 at the top of the main horizontal plate 3 completes the installation of the desktop 19 and the main horizontal plate. The horizontal movement of the desktop 19 is restricted. When it is necessary to increase the support area of ​​the desktop 19, rotate the folding plate 1 5 and the folding plate 2 6 to unfold around the connecting plate 22. The two are adjusted by rotating relative to each other through the hinge. After the sliding plate 7 is moved to the appropriate position on the inner wall of the folding plate, it is fixed with bolts 8 to enhance the support stability. When not in use, it can be folded and stored to reduce space occupation. When the desktop 19 bears weight, the folding horizontal plate 12 rotates around the fixing block 11 and transmits the pressure to the two side support legs 1 through the connecting block 13 to distribute the load and enhance the connection strength between the support legs 1 and the overall structural durability.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
