Description

Technical Field

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

[0002] With the increasing popularity of healthy office concepts, height-adjustable desks have gradually become a preferred furniture choice in modern office environments due to their ability to effectively alleviate lumbar and cervical spine discomfort caused by prolonged sitting. The growing market demand has driven the rapid development of height-adjustable desks, with modular designs becoming mainstream to meet the needs of convenient packaging and transportation as well as cost control. This often results in users needing to assemble the desks themselves after purchase.

[0003] While modular design meets the needs of logistics and transportation, the reliance on screws for final assembly has become a key bottleneck restricting the improvement of user experience and product adoption. Users must strictly follow the instructions during assembly, identifying and using a large number of screws of various sizes for connection and fixation; this is not only cumbersome but also prone to damaging components due to excessive tightening force.

[0034] This application provides a quick-assembly lifting support structure that completely eliminates the traditional screw connection method, achieving rapid assembly of the support frame 1, support legs 2, and support base 3 through a two-stage quick-assembly mechanism. For example... Figures 1 to 7 The quick-installation lifting support structure shown includes a support frame 1, support legs 2, and support bases 3. There are two support legs 2 arranged opposite each other and respectively mounted on two support bases 3. The support frame 1 is mounted on the two support legs 2. The support legs 2 include a lifting column 21 and a motor base 22. The motor base 22 is mounted on the top of the lifting column 21 and is fixedly connected to the support frame 1 through a first quick-installation structure 4. The bottom of the lifting column 21 is fixedly connected to the support base 3 through a second quick-installation structure 5.

[0035] Among them, the support frame 1 serves as the main support of the desktop, and the support legs 2 enable the lifting function. The support base 3 provides bottom support and is placed stably on the ground. The bottom of the support legs 2 is fixedly connected to the support base 3 through the second quick-release structure 5, and the top of the support legs 2 is fixedly connected to the mounting bracket 11 of the support frame 1 through the first quick-release structure 4. No screws or tools are required for assembly, which simplifies the assembly steps, improves assembly efficiency, and facilitates quick disassembly and maintenance.

[0036] In this embodiment, as Figure 2 and Figure 3 As shown, the support frame 1 includes a mounting frame 11 and a connecting beam 12. Two mounting frames 11 are arranged opposite each other and are fixedly connected by the connecting beam 12. The two mounting frames 11 are respectively fixedly connected to the two motor bases 22 by the first quick-release structure 4. The mounting frame 11 includes two parallel supporting beams 111 and a wing plate 112 disposed at one end of the two supporting beams 111. Two connecting beams 12 are arranged in parallel and are respectively connected to the two supporting beams 111 in the two mounting frames 11.

[0037] The support frame 1 consists of two symmetrical mounting frames 11 and a connecting beam 12 connecting the two mounting frames 11 to ensure the stability of the tabletop support; each mounting frame 11 includes two parallel support beams 111, and a wing plate 112 extends from one end of each beam to form a stable support frame.

[0038] See further Figure 3 As shown, the first quick-installation structure 4 includes a corresponding slot structure 41 and a block assembly 42. The slot structure 41 is opened on the sides of the two support beams 111, and its slot extends to the bottom edge of the support beam 111. The block assembly 42 is arranged on both sides of the motor base 22.

[0039] Specifically, the slot structure 41 includes a first limiting slot 411, a positioning slot 412, and a second limiting slot 413 arranged along the length of the support beam 111. The block assembly 42 includes a first limiting block 421, a second limiting block 422, and a locking tongue 423. The first limiting block 421 and the second limiting block 422 are respectively arranged corresponding to the first limiting slot 411 and the positioning slot 412, and are symmetrically arranged on both sides of the motor base 22. The locking tongue 423 is arranged corresponding to the end of the second limiting slot 413 near the motor base 22 and away from the wing plate 112.

[0040] A first horizontal groove 411a is provided extending from the bottom of the first limiting groove 411 toward the wing plate 112, and a second horizontal groove 413a is provided extending from the bottom of the second limiting groove 413 toward the wing plate 112; the positioning groove 412 is provided to gradually converge toward its bottom, and its bottom engages with the second limiting block 422, and the side of the positioning groove 412 away from the wing plate 112 is provided as an inclined surface.

[0041] The locking tongue 423 includes a positioning rod 423a and a pull rod 423b arranged perpendicularly to each other. The positioning rod 423a is located inside the motor base 22 and its two ends protrude from both sides of the motor base 22. The pull rod 423b protrudes from the side of the motor base 22 away from the wing plate 112 and can drive the positioning rod 423a to move along the direction of the second horizontal groove 413a.

[0042] During the assembly of the mounting bracket 11 and the support leg 2, the mounting bracket 11 is first placed on the ground with the slot of the slot structure 41 facing upwards. The support leg 2 is tilted and brought closer to the mounting bracket 11. First, the first limiting block 421 is inserted into the bottom of the first limiting groove 411. Then, the tilted support leg 2 is rotated so that the second limiting block 422 approaches and is inserted into the positioning groove 412. During this process, the second limiting block 422 first contacts the inclined surface of the positioning groove 412, and as it is gradually pressed towards the bottom of the groove, the first limiting block 421 slides along the first horizontal groove 411a. The locking tongue 423 is adjusted so that the end of the positioning rod 423a is inserted into the bottom of the second limiting groove 413, so that the support leg 2 and the mounting bracket 11 are assembled in place. Then, the locking tongue 423 is adjusted so that the end of the positioning rod 423a slides into the second horizontal groove 413a, completing the stable connection between the slot structure 41 and the locking block assembly 42. Figure 4 As shown.

[0043] During the adjustment of the locking tongue 423, the positioning rod 423a is moved by pulling the lever 423b, so that the end of the positioning rod 423a is locked or disengaged from the second horizontal groove 413a, thereby realizing the locking or unlocking operation between the slot structure 41 and the block assembly 42.

[0044] In this embodiment, as Figure 5 and Figure 6 As shown, the second quick-installation structure 5 includes a hook 51 and a pin 52 disposed at the bottom of the lifting column 21, and a locking assembly 53 disposed on the side of the support base 3 facing away from the lifting column 21.

[0045] Specifically, the locking assembly 53 includes a retainer 531 and a locking hook 532 disposed thereon. The locking hook 532 is rotatably connected to the retainer 531 via a connecting shaft 533, and the retainer 531 is hinged to the support base 3. Multiple hooks 51 are provided around the pin 52, and the support base 3 has a locking hole 31 and a through hole 32 corresponding to the hooks 51 and the pin 52, respectively.

[0046] During the assembly of support leg 2 and support base 3, the assembled support leg 2 and mounting bracket 11 are placed upside down on the ground, with the bottom of the lifting column 21 facing upwards; then, the side of the support base 3 with the locking component 53 is placed upwards and assembled and snapped into place with the bottom of the lifting column 21; the hook and pin 52 at the bottom of the lifting column 21 pass through the locking hole 31 and through hole 32 on the support base 3, respectively; adjust the locking base 531 and its locking hook 532 so that the locking ring at the end of the locking hook 532 is fitted onto the pin 52; finally, adjust the locking base 531 to lock the locking component 53 and the pin 52, and simultaneously lock the hook and support base 3, as shown. Figure 7 As shown.
