[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a rectangular table lamp: A rectangular table lamp includes a base 1, with a fixing seat 2 fixed to the top of the base 1 by bolts. The base 1 supports the fixing seat 2. A connecting seat 3 is slidably sleeved on the top of the fixing seat 2, ensuring the stability of the vertical movement of the connecting seat 3. A rectangular lamp body 5 is provided on the top of the connecting seat 3, providing a light source. A reinforcing mechanism 4 is disposed inside the base 1 and extends into the fixing seat 2. The reinforcing mechanism 4 improves the overall stability of the device during use. The reinforcing mechanism 4 includes a sliding joint slidably sleeved inside the base 1. There are two movable seats 406, which are symmetrically distributed at both ends of the fixed seat 2. One end of the movable seat 406 is connected to a threaded rod 405 by a thread. The threaded rod 405 is rotatably connected to the inner wall of the base 1 by a bearing. A second bevel gear 404 is welded to the outer wall of the threaded rod 405. The rotation of the second bevel gear 404 can drive the threaded rod 405 to rotate. The rotation of the threaded rod 405 can drive the two movable seats 406 to move towards each other or move away from each other. When the movable seats 406 move away from each other, the contact area between the base 1 and the table can be increased, thereby improving the overall stability of the device during use.

[0024] The bottom end of the movable base 406 is bolted with auxiliary wheels 4061. Multiple auxiliary wheels 4061 are evenly distributed at the bottom end of the movable base 406. The auxiliary wheels 4061 assist the horizontal movement of the movable base 406, improving its stability. Sliding blocks 4062 are bolted to both sides of the movable base 406. A moving groove 101 is formed on the inner wall of the base 1, matching the moving trajectory of the sliding block 4062. The sliding block 4062 and the moving groove 101 ensure the stability of the horizontal movement of the movable base 406 and prevent the movable base 406 from detaching from the base 1. The second bevel gear 404... A first bevel gear 403 is engaged at the top, and a rotating rod 402 is welded to the top of the first bevel gear 403. The top of the rotating rod 402 passes through the base 1 and extends into the interior of the fixed seat 2. The rotating rod 402 is rotatably connected to the inner wall of the base 1 and the fixed seat 2 through a bearing. The rotation of the rotating rod 402 can drive the first bevel gear 403 to rotate, and the rotation of the first bevel gear 403 can drive the second bevel gear 404 to rotate. A movable rod 401 is sleeved inside the rotating rod 402. The top of the movable rod 401 extends to the outside of the rotating rod 402, and the top of the movable rod 401 is fixedly connected to the bottom of the connecting seat 3 through a bolt. The vertical movement of the connecting seat 3 can drive the movable rod 401 to move. The movable rod 401 can move vertically inside the rotating rod 402.

[0025] A frustum 4011 is welded to the bottom of the moving rod 401. A ball bearing 4012 is provided on the outer wall of the frustum 4011. A spiral groove is provided on the inner wall of the rotating rod 402. The spiral groove is fitted with the ball bearing 4012. With this structure, the frustum 4011 can be moved when the moving rod 401 moves vertically. The movement of the frustum 4011 drives the ball bearing 4012 to move. The ball bearing 4012 moves and presses the spiral groove on the inner wall of the rotating rod 402, thereby causing the spiral groove and the rotating rod 402 to rotate. A sliding groove 201 is provided on the inner wall of the fixed seat 2. The sliding groove 201 matches the movement trajectory of the connecting seat 3. The sliding groove 201 is used to ensure the stability of the vertical movement of the connecting seat 3. An electric telescopic rod 301 is fixed to one end of the connecting seat 3 by bolts. The bottom end of the electric telescopic rod 301 is fixedly connected to the top end of the base 1 by bolts. The movement of the output end of the electric telescopic rod 301 can drive the connecting seat 3 to move vertically, thereby automatically adjusting the height of the rectangular lamp body 5.

[0026] Working principle: When it is necessary to adjust the height of the rectangular lamp body 5, first control the electric telescopic rod 301 to work. The output end of the electric telescopic rod 301 moves upward and drives the connecting seat 3 to move. The movement of the connecting seat 3 can drive the rectangular lamp body 5 to move upward, thereby adjusting the height of the rectangular lamp body 5.

[0027] Secondly, as the connecting seat 3 moves vertically upward, it drives the moving rod 401 to move upward. The movement of the moving rod 401 drives the frustum 4011 to move. The movement of the frustum 4011 drives the ball 4012 to move. The ball 4012 moves and presses the spiral groove on the inner wall of the rotating rod 402, thereby causing the spiral groove and the rotating rod 402 to rotate. The rotation of the rotating rod 402 drives the first bevel gear 403 to rotate. The rotation of the first bevel gear 403 drives the second bevel gear 404 to rotate. The rotation of the second bevel gear 404 drives the threaded rod 405 to rotate. The rotation of the threaded rod 405 drives the two moving seats 406 to move away from each other. During the process of the rectangular lamp body 5 rising vertically, the two moving seats 406 move away from each other and move out of the interior of the base 1, thereby increasing the occupied area of ​​the base 1 and the table.

[0028] Finally, the height of the rectangular lamp body 5 can be automatically adjusted by moving the output end of the electric telescopic rod 301 through mechanical transmission. At the same time as the height of the rectangular lamp body 5 is adjusted, the two moving seats 406 are moved away from each other through mechanical transmission, thereby increasing the area occupied by the base 1 and the table. Compared with the traditional rectangular lamp body 5, where the area occupied by the base 1 remains unchanged after the height is adjusted, this improves the stability of the device when the rectangular lamp body 5 is raised, and avoids the device from tipping over due to the increased center of gravity.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
