[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: a height-adjustable study table, comprising a desktop 3, table legs 4 and a telescopic leg 1 for adjusting the height of the desktop 3, the table leg 4 being detachably arranged at the bottom of the desktop 3, the lower part of the table leg 4 being a groove-shaped with an open inner side like the telescopic leg 1, the top of the telescopic leg 1 being drawable and arranged in the table leg 4, both sides of the inner cavity of the telescopic leg 1 being respectively provided with a horizontally slidable support plate 7, a spring 14 being provided between the two support plates 7, a plurality of protrusions 6 being fixedly connected to the side of the support plate 7, a plurality of grooves 5 adapted to the protrusions 6 being provided on the inner wall of the table leg 4, the top of the telescopic leg 1 being drawable and extending to the inside of the table leg 4, the protrusions 6 being embedded in different grooves 5 and the desktop 3 being at different heights.

[0018] When the height of the table needs to be adjusted, the support plate 7 and the protrusion 6 are separated from the groove 5 of the table leg 4, thereby unlocking the telescopic leg 1. Then, the telescopic leg 1 can be moved up and down to reach the desired height. Finally, the rebound force of the spring 14 causes the support plate 7 and the protrusion 6 to engage with the corresponding groove 5, thereby fixing the position of the telescopic leg 1 and completing the adjustment of the table height.

[0019] Furthermore, a rotating shaft is provided in the inner cavity of the telescopic leg 1 and at the lower part of the two support plates 7, a gear 8 is sleeved on the surface of the rotating shaft, two racks 9 meshing with the gear 8 are fixedly connected to the bottom of the support plate 7, one end of the rotating shaft is fixedly connected to a twist handle 12, and one end of the twist handle 12 extends to the inner side of the telescopic leg 1.

[0020] A gear 8 is sleeved on the surface of the rotating shaft, and the gear 8 can rotate with the rotation of the rotating shaft. When the gear 8 rotates, due to the meshing relationship with the rack 9, the rack 9 drives the support plate 7 to slide horizontally in the inner cavity of the telescopic leg 1. The gear 8 is driven to rotate by turning the twist handle 12, thereby driving the rack 9 to slide horizontally, thereby driving the support plate 7 to slide inward, so that the protrusion 6 on the support plate 7 is separated from the groove 5 of the table leg 4, and then the height is adjusted.

[0021] Furthermore, a guide rod 10 is provided between the two sides of the inner wall of the telescopic leg 1 , the two support plates 7 are respectively slidably mounted on the guide rod 10 , and the spring 14 is located on the guide rod 10 .

[0022] In this embodiment, the support plate 7 can be rebounded by setting a spring 14. When the protrusions 6 on the two support plates 7 are aligned with the grooves 5 in the table legs 4, they can be popped out by the pressure of the spring 14, and there is no need to continue to use the twist handle 12 manually to turn it out.

[0023] The two support plates 7 can be limited in position during the sliding process by the guide rods 10 to prevent the problems of unstable gravity and falling off.

[0024] Furthermore, pressing blocks are fixedly connected to the surfaces of the two support plates 7 , and the two pressing blocks extend to the inner sides of the telescopic legs 1 respectively.

[0025] It is also possible to install a pressing block on the outside of the two support plates 7, and manually press the pressing block to bring the two support plates 7 inward. After adjusting to a suitable height, release the pressing block, and through the elastic force of the spring 14, finally make the support plate 7 and the protrusion 6 engage with the corresponding groove 5, thereby fixing the position of the telescopic leg 1, and the height adjustment of the table can be completed.

[0026] Furthermore, a table top 11 is provided at the bottom of the table top 3, and the table top 11 is made of plywood.

[0027] In this embodiment, plywood is selected as the material of the table 11 because it is economical and practical, has good strength and stability, and is suitable as a structural material for storage space. When using the table 11, avoid placing heavy or sharp objects to avoid damaging the plywood.

[0028] Furthermore, anti-skid pads 2 are provided at the bottom of the two telescopic legs 1, and the anti-skid pads 2 are made of rubber.

[0029] In this embodiment, the anti-skid pad 2 is flatly attached to the bottom of the telescopic leg 1 to ensure that there are no bubbles or wrinkles. Appropriate pressure or tools can be used to make the anti-skid pad 2 fit tightly to the telescopic leg 1.

[0030] Furthermore, a reinforcing rod 13 is provided between the two telescopic legs 1 , and reinforcing ribs are provided at both ends of the reinforcing rod 13 .

[0031] In this embodiment, the reinforcing rod 13 is made of a material with high strength and good corrosion resistance, such as high-quality steel or alloy material, to ensure that it has good load-bearing capacity and durability.

[0032] The working principle and use process of the utility model: After the utility model is installed, when the height of the study table needs to be adjusted, the twist handle 12 can be turned to drive the gear 8 to rotate, thereby driving the two racks 9 to slide, and the two racks 9 respectively drive the support plate 7 to slide left and right, so that a number of protrusions 6 shrink inward, so that when the sliding telescopic leg 1 is adjusted to a suitable height, after aligning it with the groove 5 in the table leg 4, the telescopic protrusion 6 is popped out by the elastic force of the spring 14 to be fixed, thereby completing the height adjustment, or the pressing block on the telescopic leg 1 can be pressed to drive the two support plates 7 to slide left and right, and when it is adjusted to a suitable height, after aligning it with the groove 5 in the table leg 4, the pressing block can be released to fix it.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
