[0026] See also Figure 2-3 In order to make the teaching desk have the function of height adjustment, the height adjustment mechanism 5 in this embodiment includes a control seat 501 fixed on the upper surface of the base plate 4, an adjusting motor 502 is fixedly installed on the inner bottom wall of the control seat 501, an adjusting screw rod 503 is fixed on the outer surface of the output shaft of the adjusting motor 502, a threaded cylinder 504 is threadedly connected to the outer surface of the adjusting screw rod 503, a lifting plate 505 is fixed on the left and right sides of the threaded cylinder 504, a load-bearing rod 506 is fixed on the upper surface of the lifting plate 505, and a guide sleeve 507 is fixed inside the control seat 501.

[0027] The guide sleeve 507 is shaped like a cylinder with a hollow interior and missing upper and lower sides. The load-bearing rod 506 is slidably connected inside the guide sleeve 507 , and the guide sleeve 507 plays a role in guiding and positioning the load-bearing rod 506 .

[0028] A slider is fixed on the side of the lifting plate 505 away from the threaded tube 504, and the left and right side walls of the inner cavity of the control seat 501 are provided with sliding grooves for the slider to slide. When the threaded tube 504 moves, the lifting plate 505 and the slider are driven to move at the same time, and the slider slides inside the sliding groove.

[0029] One end of the load-bearing rod 506 away from the lifting plate 505 is fixed to the lower surface of the storage drawer 2, and one end of the adjusting screw rod 503 away from the adjusting motor 502 is rotatably connected to the inner top wall of the control seat 501 through a bearing.

[0030] See also Figure 4 In order to facilitate the movement of the teaching desk, the moving component 6 in this embodiment includes a positioning frame 601 fixed on the upper surface of the base plate 4, the upper surface of the positioning frame 601 is threadedly connected with a threaded rod 602 whose other end passes through and extends to the bottom of the base plate 4, the bottom end of the threaded rod 602 is rotatably connected to the top plate 603 through a bearing, and a control handle 604 is fixed to the top of the threaded rod 602.

[0031] A threaded through hole for the threaded rod 602 to pass through is formed on the upper surface of the bottom plate 4 , and the threaded through hole is threadedly connected to the threaded rod 602 .

[0032] It should be noted that when the teaching desk needs to be moved, the top plate 603 is not in contact with the ground, and the roller 7 is in contact with the ground. When the teaching desk does not need to be moved, the top plate 603 is in contact with the ground, and the roller 7 is suspended in the air.

[0033] The standard parts used in this application can all be purchased from the market, and special-shaped parts can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets and welding in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0034] If the present application discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously not possible to use an one-piece molding process).

[0035] The working principle of the above embodiment is:

[0036] (1) During teaching activities, the desk top 1 of the teaching desk provides a space for students to study, and the storage drawer 2 provides a space for placing learning items. When the height of the teaching desk needs to be adjusted, the adjustment motor 502 is started, and the output shaft of the adjustment motor 502 starts to rotate, driving the adjustment screw 503 to start rotating. The threaded barrel 504 moves upward or downward with the rotation of the adjustment screw 503. The movement of the threaded barrel 504 drives the lifting plate 505 to move at the same time. The movement of the lifting plate 505 drives the load-bearing rod 506 to move at the same time. At this time, the load-bearing rod 506 slides inside the guide sleeve 507.

[0037] (2) As the load-bearing rod 506 moves, the storage drawer 2 and the desk top 1 move upward or downward, thereby achieving the purpose of height adjustment, so that the teaching desk can adapt to students of different heights. When the teaching desk needs to be moved, the user holds the control handle 604 and then rotates the control handle 604 to drive the threaded rod 602 to start rotating. The top plate 603 moves upward with the rotation of the threaded rod 602. When the top plate 603 is not in contact with the ground and the roller 7 is in contact with the ground, the rotation of the control handle 604 is stopped, and the entire teaching desk is moved by the roller 7, saving the effort spent on moving the teaching desk.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
