Description

Technical Field

[0001] This utility model relates to the field of table supports, and in particular to a novel table support structure. Background Technology

[0002] An existing patent (publication number: CN201011938Y) discloses a table support, including a base, a support column on the base, and a bracket on the upper part of the support column to support the tabletop. The upper end of the support column has at least one diagonal brace, which includes a support plate roughly in the shape of a right angle triangle, a mounting plate on the vertical right-angled side of the support plate that surrounds the support column, and a support plate on the horizontal right-angled side. The mounting plate is connected to the support column, and the support plate is connected to the tabletop. However, the "support column" structure in this device is relatively fixed, and it does not allow for adjustment of the tabletop support height based on the user's height and usage scenario, resulting in poor structural flexibility and drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a novel table support structure that offers stable support, flexible structure, and adjustable tabletop support height based on user height and usage scenario. Through personalized adaptation, it enhances user comfort while allowing for quick and easy adjustment of the tabletop support height without the need for tools.

[0004] The objective of this utility model is achieved through the following technical solution: A novel table support structure includes a tabletop, a fixed frame, a support sleeve, a rotating sleeve, a cover plate, a locking sleeve, and a threaded rod. The tabletop is connected to the fixed frame at its lower part. The fixed frame has fixed plates on both sides, and the tabletop is connected to the upper part of the fixed plates. The fixed frame has multiple reinforcing beams on its inner side and a support rod with a rack in its middle. The support sleeve has support legs connected to both sides. The support sleeve has mounting sleeves on its outer side and a slide rail inside. The slide rail is adapted to the support rod, and the support rod is connected to the slide rail and slides within the slide rail. The support rod is in contact with the cover plate, and the mounting sleeve is connected to the lower part of the cover plate. The cover plate has a retaining plate, and the support rod has a retaining groove. The retaining plate is adapted to the retaining groove, and the retaining plate is connected to the retaining groove.

[0005] The mounting sleeve of this utility model is connected to the rotating sleeve by a shaft. The shaft passes through the mounting sleeve and the rotating sleeve in sequence. The rear end of the rotating sleeve is connected to the shaft by a screw. The screw connects the rotating sleeve and the shaft in sequence. The rotating sleeve has a gear on the outside. The mounting sleeve has a side through hole. The gear is adapted to the side through hole. The gear passes through the side through hole and meshes with the rack. The gear is connected to the rack.

[0006] The front end of the rotating sleeve of this utility model passes through the lock sleeve, the lock sleeve has a locking block, the rotating sleeve has multiple locking grooves, the locking block is adapted to the locking grooves, the locking block is connected to the locking grooves, the gear is fitted to the inner side of the lock sleeve, and the support sleeve is fitted to the outer side of the lock sleeve. Beneficial effects

[0007] This utility model's fixing frame increases the support area of ​​the support rod for fixing the tabletop through two side fixing plates and multiple inner reinforcing beams, ensuring the stability of the support rod for fixing the tabletop and preventing the tabletop from tilting. The support rod is sleeved with the support sleeve, and the meshing of gears and racks allows for corresponding adjustment of the support rod's fixing height to meet the needs of users of different heights. By adjusting the table to a reasonable height, it ensures that users maintain a correct sitting posture while working, reducing fatigue and discomfort caused by improper posture, thereby improving work efficiency and concentration.

[0008] This utility model features a locking sleeve at the front end of the rotating sleeve. The locking sleeve can be driven and positioned by rotating a knob. When the locking sleeve moves until the locking block is embedded in the locking groove, it adds a positioning fulcrum for the rotating sleeve. At this point, the gears and rack are braked and locked, preventing movement, thus reinforcing the stability of the support sleeve's support force on the support rod. When the locking sleeve moves until the locking block is completely disengaged from the locking groove, the positioning fulcrum for the rotating sleeve disappears. At this point, the tabletop support height can be adjusted according to the user's height and usage scenario. This personalized adaptation improves user comfort and allows for adjustments based on height growth or changing needs, avoiding resource waste caused by frequent table and chair replacements, extending the table's lifespan. The structure is flexible, and the position can be quickly adjusted without tools, making operation convenient.

[0009] This utility model provides stable support and flexible structure. The tabletop support height can be adjusted according to the user's height and usage scenario. Through personalized adaptation, it improves user comfort and allows for quick and easy adjustment of the tabletop support height without the need for tools. Attached Figure Description

The tabletop 01 is connected to the lower part of the fixing frame 02. The fixing frame 02 has fixing plates 25 on both sides, and the tabletop 01 is connected to the upper part of the fixing plates 25. The fixing frame 02 has multiple reinforcing beams 03 on its inner side, and a support rod 04 with a rack 07 in its middle. The support sleeve 05 has support legs 06 connected to both sides. The support sleeve 05 has mounting sleeves 22 on its outer side, and a slide rail 24 inside. The slide rail 24 is adapted to the support rod 04, and the support rod 04 slides within the slide rail 24. The support rod 04 fits against the cover plate 11, and the lower part of the cover plate 11 is connected to... The mounting sleeve 22 is connected to the cover plate 11, which has a retaining plate 12. The support rod 04 has a retaining groove 13. The retaining plate 12 and the retaining groove 13 are adapted to each other. The retaining plate 12 connects to the retaining groove 13.
