[0001] This utility model relates to the field of height-adjustable desk technology, and in particular to a height-adjustable desk leg fixing structure. Background Technology

[0002] In modern office and home settings, height-adjustable desks have become a popular choice due to their adjustable height and adaptability to different usage needs. As a key component of height-adjustable desks, the connection structure between the desk legs and the support plate directly affects the product's installation efficiency, operational stability, and ease of maintenance.

[0003] Currently, the vast majority of height-adjustable desks on the market still rely on traditional screw fastening to connect the legs and support plates. From an installation perspective, during installation, tools are needed to tighten each screw individually to secure the legs and support plates, a cumbersome process that consumes a significant amount of time and manpower. Disassembly also requires using tools to loosen the screws in reverse, demanding a high level of user skill. Furthermore, repeated disassembly and reassembly can cause thread wear, reducing connection stability and product lifespan. In addition, if positioning deviations occur during assembly, readjustment is necessary, further impacting assembly efficiency. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a fixing structure for the lifting table legs, which enables screwless and rapid assembly and disassembly between the lifting table legs and the support plate, making it convenient for users and improving the stability and reliability of the lifting table.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The snap-fit ​​component includes a movable snap-fit ​​part and an elastic reset part. The snap-fit ​​part moves when the height-adjustable table leg is inserted and engages with the snap-fit ​​hole on the height-adjustable table leg through the elastic reset part. A clamping component is provided on the support plate. The height-adjustable table leg has a part for the clamping component to be inserted to form a clamping position. When the height-adjustable table leg is inserted into the connecting hole, the clamping component clamps the height-adjustable table leg from the inside and outside, and cooperates with the snap-fit ​​component to achieve screwless fixing of the height-adjustable table leg.

[0035] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0036] Please see Figure 1-11 A lifting table leg fixing structure includes a lifting table leg 1 and a support plate 2. The support plate 2 has a connecting hole 21 for the lower end of the lifting table leg 1 to be inserted. The support plate 2 has a snap-fit ​​member 3, which includes a movable snap-fit ​​part and an elastic reset part. The snap-fit ​​part moves when the lifting table leg 1 is inserted and engages with the snap-fit ​​hole 12 on the lifting table leg 1 through the elastic reset part. The support plate 2 has a clamping member 4, and the lifting table leg 1 has a part for the clamping member 4 to be inserted to form a clamping position. When the lifting table leg 1 is inserted into the connecting hole 21, the clamping member 4 clamps the lifting table leg 1 from the inside and outside, and cooperates with the snap-fit ​​member 3 to achieve screwless fixing of the lifting table leg 1.

[0037] The snap-fit ​​component 3 also includes a mounting shell 31, and the snap-fit ​​part includes a movable block 32. The movable block 32 is movably disposed inside the mounting shell 31. The lifting table leg 1 is provided with a snap hole 12, and the movable block 32 is provided with a snap-fit ​​end 321 that is adapted to the snap hole 12.

[0038] The elastic reset component is a spring 33 in use. The moving block 32 is provided with a mounting groove 323. One end of the spring 33 is located in the mounting groove 323, and the other end contacts the side wall of the mounting shell 31. The spring 33 provides automatic reset elastic force for the moving block 32, so that the locking end 321 can quickly lock into the locking hole 12 when the lifting table leg 1 is inserted, realizing automatic locking. The mounting groove 323 on the moving block 32 precisely positions the spring 33, preventing the spring 33 from shifting, ensuring stable transmission of elastic force, and enhancing the reliability of locking.

[0039] Multiple clamping components 4 are provided. Each clamping component 4 includes a main body block 41. The main body block 41 is provided with a clamping end 42 and a clamping plate 43. A clamping groove is formed between the clamping end 42 and the clamping plate 43 for the insertion of the lifting table leg 1. The clamping component 4 constructs a clamping groove through the main body block 41, the clamping end 42, and the clamping plate 43, providing guidance and initial limitation for the insertion of the lifting table leg 1. The clamping end 42 and the clamping plate 43 act from the inside and outside respectively to form a basic clamping structure, which initially enhances the stability of the table leg fixation.

[0040] Two clamping plates 43 are provided, which are symmetrically distributed on both sides of the clamping end 42. The two clamping plates 43 and the clamping end 42 together form a three-point clamping structure that coordinates the inner and outer clamping of the corner of the lifting table leg 1. The two symmetrically distributed clamping plates 43 are balanced by the force. The clamping end 42 and the two clamping plates 43 on both sides form a three-point clamping structure, which builds a stable mechanical support system and effectively improves the fixing strength of the lifting table leg 1 connection.

[0041] The clamping end 42 is provided with a guide end 44 with a beveled structure. The two sides of the clamping end 42 extend toward the clamping plate 43 to form bent ends 45. The two clamping ends 42 are set at right angles and are adapted to the inner right-angle corners of the lifting table leg 1. The beveled guide end 44 of the clamping end 42 guides the lifting table leg 1 to quickly align and insert, reducing the difficulty of installation. The bent ends 45 set at right angles on both sides are adapted to the inner right-angle corners of the table leg to achieve surface contact clamping, increase friction, and enhance clamping stability.

[0042] The mounting shell 31 is composed of an upper shell 311 and a lower shell 312. The lower shell 312 is symmetrically provided with upwardly extending limiting plates 3121. A sliding groove 3122 is formed between the limiting plates 3121 for the sliding block 32 to slide. The sliding block 32 is located in the sliding groove 3122. The structure of the upper and lower shells 312 of the mounting shell 31 facilitates the assembly and maintenance of internal components (such as the sliding block 32 and the spring 33). The limiting plates 3121 and the sliding groove 3122 of the lower shell 312 provide guidance for the sliding block 32, constrain its linear movement, ensure that the snap-fit ​​end 321 is accurately snapped into the snap-fit ​​hole 12, and improve the snap-fit ​​reliability.

[0043] The movable block 32 is provided with an insertion hole 322. The snap-fit ​​component 3 also includes a control board 34 that is inserted into the insertion hole 322 to drive the movable block 32 to move. The bottom of the mounting shell 31 and the bottom of the support pad 2 are both provided with a moving hole 3123. The upper end of the control board 34 passes through the moving hole 3123 and is located in the insertion hole 322 of the movable block 32. Through the moving hole 3123 at the bottom of the mounting shell 31 and the support pad 2, a manual control interface is provided for the disassembly operation, so that the user can control the movement of the movable block 32 and the snap-fit ​​end 321 can be quickly disengaged from the snap-fit ​​hole 12 to achieve convenient disassembly.

[0044] The control board 34 is provided with a groove 341 for the spring 33. One end of the spring 33 located in the moving block 32 abuts against the groove 341, which securely installs the control board 34 in the socket 322. The groove 341 on the control board 34 abuts against the spring 33 to prevent the control board 34 from falling out of the socket 322 and to ensure the stability of the position of the control board 34.

[0045] The lower end of the lifting table leg 1 is provided with a connecting plate 11. The connecting plate 11 has multiple slots 111 corresponding to the clamping parts 4. The clamping end 42 is inserted into the inner side of the lifting table leg 1 through the slots 111 and works with the clamping plate 43 to clamp the lifting table leg 1. The upper surface of the connecting plate 11 at the lower end of the lifting table leg 1 is flush with the lower side of the locking hole 12. When the lifting table leg 1 is inserted into the connecting hole 21 and the locking is completed, the lower surface of the locking end 321 of the moving block 32 passes through the locking hole 12 and contacts the upper surface of the connecting plate 11. The connecting plate 11 can share the pressure of the locking end 321, reduce the fatigue risk of the surrounding materials of the locking hole 12, and extend the service life of the fixed structure of the lifting table leg 1.

[0046] When it is necessary to disassemble the lifting table leg 1, the control plate 34 is operated and moved towards the spring 33. The control plate 34 drives the moving block 32 to slide in the moving groove 3122 formed by the limit plate 3121, so that the locking end 321 is moved out of the locking hole 12, thereby releasing the locking. At this time, the lifting table leg 1 can be pulled out from the connecting hole 21 to complete the quick disassembly of the table leg.

[0047] When installing the lifting table leg 1, align the lower end of the lifting table leg 1 with the connecting hole 21 on the support pad 2 and insert it. During insertion, the lifting table leg 1 will push the moving block 32 in the locking piece 3. Since the moving block 32 has a locking end 321 that matches the locking hole 12, and the moving block 32 is connected to the mounting shell 31 by a spring 33, the moving block 32 will compress the spring 33 and move after being pushed by the lifting table leg 1. When the locking end 321 is aligned with the locking hole 12 on the lifting table leg 1, the elastic force of the spring 33 causes the locking end 321 to insert into the locking hole 12 to achieve locking. At the same time, the slot 111 on the connecting plate 11 at the lower end of the lifting table leg 1 corresponds to the clamping piece 4 on the support pad 2. Multiple clamping components 4 have clamping ends 42 inserted into the inner side of the lifting table leg 1 through slots 111. Two clamping plates 43, symmetrically distributed on both sides of the clamping ends 42, are located on the outer side of the lifting table leg 1, forming inner and outer clamping at multiple corners of the lifting table leg 1. The guide end 44 on the clamping end 42 has a beveled structure, which can guide the lifting table leg 1 to be smoothly inserted into the clamping slot, improving the ease of installation. Furthermore, the bent ends 45 on both sides of the clamping end 42 are set at right angles, which are adapted to the inner right-angle corners of the lifting table leg 1, increasing the contact area and further enhancing the stability of clamping. This enables the lifting table leg 1 to be quickly assembled and disassembled without screws, meeting the user's need for portable assembly and disassembly of the lifting table.

[0048] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
