Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to an adjustable table leg locking mechanism. Background Technology

[0002] In the field of modern furniture design and manufacturing, the convenience and practicality of the table's structure have always been key areas of research and improvement. In particular, the way the table legs connect to the tabletop has a significant impact on the table's assembly efficiency, ease of transport, and stability during use.

[0003] Traditional table assembly mostly relies on screws to fix the table legs to the tabletop. While this connection method ensures a certain degree of stability, it exposes many problems in actual use. From an assembly perspective, users need to use specialized tools such as screwdrivers to tighten the screws in a specific order and torque, making the process complex and time-consuming, and extremely unfriendly to users with limited hands-on skills. In terms of transportation, because it cannot be quickly disassembled, the table's volume is difficult to compress, not only taking up a lot of transport space and increasing logistics costs, but also making it prone to loosening or damage to parts due to collisions during handling. After long-term and frequent use, the screw connections may loosen due to thread wear, affecting the table's stability and even posing safety hazards, while also shortening the table's lifespan. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an adjustable table leg locking mechanism. This mechanism enables quick and convenient connection and separation between the table legs and the table frame, improving assembly efficiency, reducing transportation costs, and ensuring the stability and reliability of the connection.

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

[0006] An adjustable table leg locking mechanism includes a table frame, table legs, and a connector. The table frame has a snap-fit ​​groove. The connector includes a snap-fit ​​part and a drive mechanism for moving the snap-fit ​​part. The snap-fit ​​part includes a snap-fit ​​end that can be inserted into the snap-fit ​​groove to achieve snap-fit. One end of the connector can cooperate with the table frame to form a rotation fulcrum. The table legs are snap-fitted to the table frame through the connector. Operating the drive mechanism moves the snap-fit ​​part to change the connection state between the table legs and the table frame.

[0007] Preferably, the snap-fit ​​component is a snap-fit ​​plate, the snap-fit ​​end is disposed on the snap-fit ​​plate, and the snap-fit ​​plate is connected to the drive mechanism.

[0008] Preferably, the snap-fit ​​end is composed of end body one and end body two, with a recessed groove formed between them. End body one has a beveled surface and is located above end body two. The snap-fit ​​groove on the table frame is opened corresponding to end body one and end body two.

[0009] Preferably, the driving mechanism includes a rotating shaft, on which a control component is provided to drive the movement of the snap-fit ​​plate. The rotating shaft is connected to the snap-fit ​​plate through the control component. The rotating shaft is rotatably disposed within the connecting component. A torsion spring for resetting is sleeved on the rotating shaft. The rotating shaft is provided with a mounting groove for one end of the torsion spring to be snapped into. When it is necessary to change the connection state between the table leg and the table frame, the rotating shaft is operated to rotate. The power generated by the rotation of the rotating shaft is transmitted to the snap-fit ​​plate through the control component, driving the snap-fit ​​plate to move in a predetermined direction, which can achieve precise engagement or smooth separation of the snap-fit ​​end and the snap-fit ​​groove.

[0010] Preferably, two snap-fit ​​plates are symmetrically provided, and both snap-fit ​​plates are connected to the gear through meshing ends. The snap-fit ​​ends of the two snap-fit ​​plates are located on the upper and lower sides of the gear, respectively. By having the snap-fit ​​ends located on the upper and lower sides of the gear, the gear can synchronously drive the two snap-fit ​​plates meshing with it to move synchronously in opposite directions when it rotates.

[0011] Preferably, the control component includes a gear and a meshing end. The gear is sleeved on the rotating shaft, and the meshing end is disposed on the snap-fit ​​plate and meshes with the gear. By meshing with the meshing end, the gear can convert the rotational motion into the linear movement of the snap-fit ​​plate, so that the snap-fit ​​plate can accurately snap into or disengage from the snap-fit ​​groove.

[0012] Preferably, the connector further includes a snap-fit ​​box, a mounting block, and a positioning plate. The positioning plate is located inside the snap-fit ​​box and snaps into it. The mounting block is disposed between the snap-fit ​​box and the positioning plate and is fixed inside the snap-fit ​​box by the positioning plate. The positioning plate can fix the mounting block inside the snap-fit ​​box, so that the mounting block can provide stable support for the rotating shaft and the snap-fit ​​plate.

[0013] Preferably, the rotating shaft is rotatably mounted on the mounting block, with one end of the rotating shaft having a mounting groove passing through the snap-fit ​​box and exposed to the outside. The mounting block has a moving groove on the side near the snap-fit ​​plate, and the snap-fit ​​plate is movably mounted in the moving groove. The snap-fit ​​plate is located between the moving groove and the positioning plate, and the moving groove plays a guiding role to ensure that the snap-fit ​​plate will not deviate during movement.

[0014] Preferably, the table frame is further provided with a limiting end block and a positioning end block, and the snap-fit ​​box is provided with a positioning slot and a connecting slot. The positioning slot and the positioning end block cooperate to position the fulcrum for the rotation of the connector. The connecting slot and the limiting end block cooperate to limit the rotating connector. During installation, the connector or table frame is rotated with the cooperation of the positioning slot and the positioning end block as the fulcrum, so that the snap-fit ​​end is inserted into the snap-fit ​​slot. The limiting end block and the connecting slot determine the relative position to ensure accurate snap-fit ​​position.

[0015] Preferably, the snap-fit ​​box is also provided with a through hole for the snap-fit ​​end to pass through. The snap-fit ​​end passes through the through hole and is fitted and snapped into the snap-fit ​​groove. The through hole ensures that the snap-fit ​​end can be smoothly snapped into the snap-fit ​​groove on the table frame. The through hole not only provides a movement path for it, but also plays a guiding and positioning role, ensuring that the snap-fit ​​end can accurately complete the snap-fit ​​or disengagement operation with the snap-fit ​​groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention abandons the traditional screw fastening method. By operating the rotating shaft and utilizing the precision transmission of gears and meshing ends, the snap-fit ​​end and snap-fit ​​groove can be quickly engaged and disengaged. This meets the user's needs for quick table assembly and storage, significantly improves operational convenience, and allows users to easily complete the installation and disassembly of the table. At the same time, the table legs and table frame can be quickly separated, greatly reducing the transportation volume and transportation costs, and bringing great convenience to furniture transportation and storage.

Example

[0032] Please see Figure 1-8 An adjustable table leg locking mechanism includes a table frame 1, table legs 2, and a connector 3. The table frame 1 is provided with a snap-fit ​​groove 13. The connector 3 includes a snap-fit ​​part and a drive mechanism for moving the snap-fit ​​part. The snap-fit ​​part includes a snap-fit ​​end 391 that can be inserted into the snap-fit ​​groove 13 to achieve snap-fit. One end of the connector 3 can cooperate with the table frame 1 to form a rotation fulcrum. The table legs 2 are snap-fitted to the table frame 1 through the connector 3. The drive mechanism is operated to move the snap-fit ​​part to change the connection state between the table legs 2 and the table frame 1.

[0033] The snap-fit ​​component is a snap-fit ​​plate 39, with a snap-fit ​​end 391 located on the snap-fit ​​plate 39. The snap-fit ​​plate 39 is connected to the drive mechanism. The snap-fit ​​end 391 consists of end body 1 3911 and end body 2 3912, forming a recessed groove between them. End body 1 3911 has a beveled surface located above end body 2 3912. The snap-fit ​​groove 13 on the table frame 1 is correspondingly opened with end body 1 3911 and end body 2 3912. During installation, the beveled surface of end body 1 3911 guides the snap-fit ​​end 391 to quickly align with the snap-fit ​​groove 13, reducing assembly difficulty. End body 2 3912 and the snap-fit ​​groove 13 increase the contact area, improving connection stability. The groove optimizes the structure, reduces weight, and avoids stress concentration. The combination of these three components makes the snap-fit ​​end 391 and the snap-fit ​​groove 13 more compatible, ensuring the reliability of the snap-fit ​​between the table leg 2 and the table frame 1.

[0034] The driving mechanism includes a rotating shaft 36, on which a control component is provided to drive the movement of the snap-fit ​​plate 39. The rotating shaft 36 is connected to the snap-fit ​​plate 39 through the control component. The rotating shaft 36 is rotatably disposed within the connecting member 3. A torsion spring 37 for resetting is sleeved on the rotating shaft 36. The rotating shaft 36 is provided with a mounting groove 361 for one end of the torsion spring 37 to be snapped into. When it is necessary to change the connection state between the table leg 2 and the table frame 1, the rotating shaft 36 is operated to rotate. The power generated by the rotation of the rotating shaft 36 is transmitted to the snap-fit ​​plate 39 through the control component, driving the snap-fit ​​plate 39 to move in a predetermined direction. This enables precise engagement or smooth separation of the snap-fit ​​end 391 and the snap-fit ​​groove 13. The torsion spring 37 can provide restoring force to the rotating shaft 36, thereby enabling the snap-fit ​​plate 39 to automatically reset after each movement.

[0035] Two snap-fit ​​plates 39 are symmetrically provided. Both snap-fit ​​plates 39 are connected to the gear 38 through the meshing end 392. The snap-fit ​​ends 391 of the two snap-fit ​​plates 39 are located on the upper and lower sides of the gear 38, respectively. By the snap-fit ​​ends 391 being located on the upper and lower sides of the gear 38, the gear 38 can synchronously drive the two snap-fit ​​plates 39 that are meshed with it to move synchronously in opposite directions when it rotates.

[0036] The control component includes a gear 38 and a meshing end 392. The gear 38 is sleeved on the rotating shaft 36, and the meshing end 392 is located on the snap-fit ​​plate 39 and meshes with the gear 38. By meshing with the meshing end 392, the gear 38 can convert the rotational motion into the linear movement of the snap-fit ​​plate 39, so that the snap-fit ​​plate 39 can accurately snap into or disengage from the snap-fit ​​groove 13.

[0037] The connector 3 also includes a snap-fit ​​box 31, a mounting block 35, and a positioning plate 34. The positioning plate 34 is located inside the snap-fit ​​box 31 and snaps into it. The mounting block 35 is located between the snap-fit ​​box 31 and the positioning plate 34 and is fixed inside the snap-fit ​​box 31 by the positioning plate 34. The positioning plate 34 can fix the mounting block 35 inside the snap-fit ​​box 31, so that the mounting block 35 can provide stable support for the rotating shaft 36 and the snap-fit ​​plate 39. The snap-fit ​​box 31 is composed of a cover plate 311 and a box body 312. After the mounting block 35 is installed inside the box body 312 by the positioning plate 34, the cover plate 311 is closed, and finally the complete snap-fit ​​box 31 is formed.

[0038] The rotating shaft 36 is rotatably mounted on the mounting block 35. One end of the rotating shaft 36 has a mounting groove 361 that passes through the snap-fit ​​box 31 and is exposed to the outside. The mounting block 35 has a moving groove 351 on the side near the snap-fit ​​plate 39. The snap-fit ​​plate 39 is movably mounted in the moving groove 351. The snap-fit ​​plate 39 is located between the moving groove 351 and the positioning plate 34. The moving groove 351 plays a guiding role to ensure that the snap-fit ​​plate 39 will not deviate during movement.

[0039] The table frame 1 is also provided with a limiting end block 12 and a positioning end block 11. The snap-fit ​​box 31 is provided with a positioning slot 32 and a connecting slot 33. The positioning slot 32 and the positioning end block 11 cooperate to position the fulcrum for the rotation of the connector 3. The connecting slot 33 and the limiting end block 12 cooperate to limit the rotating connector 3. During installation, the connector 3 or the table frame 1 is rotated with the cooperation of the positioning slot 32 and the positioning end block 11 as the fulcrum, so that the snap-fit ​​end 391 is inserted into the snap-fit ​​slot 13. The limiting end block 12 and the connecting slot 33 determine the relative position to ensure accurate snap-fit ​​position.

[0040] The snap-fit ​​box 31 is also provided with a through hole 313 for the snap-fit ​​end 391 to pass through. The snap-fit ​​end 391 passes through the through hole 313 and is fitted and snapped into the snap-fit ​​groove 13. The through hole 313 ensures that the snap-fit ​​end 391 can be smoothly snapped into the snap-fit ​​groove 13 on the table frame 1. The through hole 313 not only provides a movement path for it, but also plays a guiding and positioning role, ensuring that the snap-fit ​​end 391 can accurately complete the snap-fit ​​or snap-unscrew operation with the snap-fit ​​groove 13.

[0041] During installation, the positioning end block 11 on the table frame 1 first engages with the positioning slot 32 on the snap-fit ​​box 31. Using the engagement between the positioning end block 11 and the positioning slot 32 as a fulcrum, the connecting box is rotated towards the table frame 1 or the table frame 1 is rotated towards the table leg 2. The beveled surface on its snap-fit ​​end 391 pushes the snap-fit ​​plate 39 inward, tightening the torsion spring 37. After the snap-fit ​​box 31 is rotated until the limiting end block 12 engages with the connecting slot 33, the snap-fit ​​end 391 on the snap-fit ​​plate 39 is aligned with the snap-fit ​​slot 13. The force released by the torsion spring 37 drives the rotating shaft 36 to rotate. The rotating shaft 36 drives the positioning plate 34, which is engaged with the gear 38, to move. The snap-fit ​​end 391 of the positioning plate 34 moves into the snap-fit ​​slot 13 to complete the snap-fit, realizing the quick connection between the table leg 2 and the table frame 1.

[0042] When disassembling table leg 2, the rotating shaft 36 can be rotated through the mounting slot. The rotating shaft 36 drives the gear 38 to rotate. The gear 38 engages with the meshing end 392 on the snap-fit ​​plate 39, driving the two snap-fit ​​plates 39 to move synchronously in opposite directions. This causes the snap-fit ​​end 391 to move out of the snap-fit ​​groove 13 on the table frame 1. Then, using the positioning end block 11 of the table frame 1 as the fulcrum, the table leg 2 and the connector 3 are rotated outward together, causing the limiting end block 12 to separate from the connecting slot 33. This allows the table leg 2 and the connector 3 to be removed from the table frame 1, completing the quick disassembly.

[0043] 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.
