[0001] The utility model relates to the technical field of study desks, and more specifically, to a tabletop sliding adjustment mechanism and a study desk and chair. Background Art

[0002] A study desk and chair includes a base assembly, a table assembly, and a chair assembly, and the table assembly is connected to the base assembly. To ensure that the study desk and chair can adapt to users of different body types, it is required that at least one of the table and chair in the study desk and chair can be adjusted forward and backward. This forward and backward adjustment design allows users to adjust according to their own height and body type needs, thus providing a more personalized and comfortable use experience.

[0003] Due to the need for desk work on the table assembly, it must have a certain load-bearing capacity. How to ensure the stability and reliability of the adjustment mechanism of the tabletop, and how to further improve its comfort and durability need further research. Summary of the Invention

[0004] The utility model aims to solve one of the technical problems in the related technologies to a certain extent. For this purpose, the utility model provides a tabletop sliding adjustment mechanism, which provides stable guidance and support for the tabletop by setting a slide rail and a slider to form a linear guiding structure; the rib design and the rolling elements cooperate to reduce the frictional resistance, and the adjustment is smoother; the structure is simple and easy to manufacture.

[0005] The utility model also provides a study desk with the above tabletop sliding adjustment mechanism.

[0006] The technical solution adopted by the utility model is as follows: A tabletop sliding adjustment mechanism is provided, including:

[0048] The top of the slider 9 is provided with ribs 91 arranged along the sliding direction, and the bottom of the slider 9 is provided with a rolling body.

[0049] By combining Figure 3-4 It can be seen that two spaced and parallel slide rails 7 are fixedly installed at the bottom of the table top 2, which helps to enhance the stability and load-bearing capacity of the table top 2. The structure of the slide rail 7 includes a top plate 71, a bottom plate 72 and a side plate 73, and when the slider 9 slides with it, the rolling body contacts the bottom plate 72 and the rib 91 contacts the top plate 71, thereby achieving a smooth sliding process. In addition, the special design of the slide rail 7, that is, the lateral opening, helps to install and adjust the position of the slide rail 7, and improves the flexibility and convenience of the adjustment mechanism.

[0050] As for the material selection of the table top 2, the present embodiment adopts plastic material. This selection may be made in consideration of the light weight and easy processing of the plastic material, while also meeting the strength and stability requirements of the table top 2. In other embodiments, the table top 2 may be made of wood or aluminum alloy, depending on the specific usage scenario and needs. Table tops 2 of different materials may have different appearances, weights, costs, and other characteristics, and users can choose according to their preferences and needs.

[0051] Finally, in order to ensure the load-bearing capacity of the slide rail 7, sheet metal is used in this embodiment to manufacture the slide rail 7 and the support plate 4.

The elastic arm 94a is always kept in elastic contact with the inner wall of the slide rail 7, which provides additional support and stability, and ensures the smoothness and reliability of the sliding process. The bottom of the slider 9 is provided with a mounting hole 92 for mounting the rolling body. The middle portion of the slider 9 is provided with a material reduction groove 94b; by providing the material reduction groove 94b on the slider 9, the amount of material used can be effectively reduced, while reducing costs and improving manufacturing efficiency. The use of an integrated injection molding process to manufacture the slider 9 can ensure the consistency and quality stability of the components, while simplifying the production process and reducing manufacturing costs.

[0055] Furthermore, a fastening hole 93 is provided on the side of the slider 9 , and a fastener passes through the fastening hole 93 to fix the plastic slider 9 to the sheet metal support plate 4 .

[0056] Specifically, combined Figure 7 As shown, a locking device 8 is provided between the slide rail 7 and the support plate 4, and the locking device 8 switches back and forth between a locked state and an unlocked state. In the locked state, the slide rail 7 and the support plate 4 are relatively fixed in position, and in the unlocked state, the slide rail 7 and the support plate 4 can move relatively. The locking device 8 includes a limiting claw 81 elastically mounted on the slide rail 7, and the support plate 4 is provided with a group of card slots 41 adapted to the limiting claw 81.
