[0028] Reference Figure 1-5 As shown, two cover plates 21 are slidingly connected to the upper surface of the desk body 1, one side of one of the cover plates 21 is rotatably connected to an L-shaped plate 22, a slope 23 is provided at the short arm end of the L-shaped plate 22, a limiting groove 24 is provided at the short arm end of the L-shaped plate 22, one side of the other cover plate 21 is fixedly connected to a limiting buckle 25, the size of the limiting buckle 25 is adapted to the size of the limiting groove 24, one side of the L-shaped plate 22 is fixedly connected to a spring 26, one end of the spring 26 is fixedly connected to one of the cover plates 21. When the desk body 1 is not needed, the two cover plates 21 are brought closer to each other, the inclined surface 23 of the L-shaped plate 22 on one of the cover plates 21 squeezes the limit buckle 25, the L-shaped plate 22 rotates, and the spring 26 deforms. When the short arm end of the L-shaped plate 22 moves over the limit buckle 25, the L-shaped plate 22 rotates back to its original position under the action of the restoring elastic force of the spring 26, and the limit buckle 25 enters the limit groove 24 of the L-shaped plate 22, thereby achieving the effect of fixing the two cover plates 21. At this time, the two cover plates 2 1 for storage. When the desk body 1 needs to be used, the L-shaped plate 22 is rotated to remove the limiting buckle 25 from the limiting groove 24 of the L-shaped plate 22. At this time, the two cover plates 21 are moved away from each other. When the cover plates 21 are moved to a suitable position, the movement of the cover plates 21 is stopped. The two cover plates 21 set by the extension device 2 increase the area above the desk body 1, thereby making it convenient for students to place learning materials and experimental equipment on the cover plates 21, thereby improving the practicality of the desk body 1.
[0029] Reference Figure 1-5 As shown, a groove 28 is provided on the upper surface of the cover plate 21, and the cross section of the groove 28 is rectangular. When the staff needs to move the cover plate 21, the staff inserts a finger into the groove 28 to move the cover plate 21, which brings convenience to the staff to move the cover plate 21. A handle 27 is fixedly connected to one side of the L-shaped plate 22, and the surface of the handle 27 is provided with anti-slip grooves. By providing the handle 27, the effect of facilitating the staff to rotate the L-shaped plate 22 is achieved, which brings convenience to the staff. Slide grooves 210 are provided on both sides of the cover plate 21, and a slider 29 is fixedly connected to the corresponding slide groove 210 of the desk body 1 by means of a support plate, and the slider 29 is slidably adapted to the slide groove 210. By moving the slider 29 inside the slide groove 210 of the cover plate 21, the maximum displacement and moving direction of the cover plate 21 are limited, thereby preventing the cover plate 21 from falling off the desk body 1.
[0030] Reference Figure 1-5As shown, the auxiliary device 3 includes a threaded barrel 31, one end of which is rotatably connected to the bottom of the cover plate 21, a screw rod 32 is connected to the inner thread of the threaded barrel 31, and a bottom plate 33 is fixedly connected to the end of the screw rod 32 away from the threaded barrel 31. When the desk body 1 needs to be used and the two cover plates 21 are moved to the two sides of the desk body 1, the threaded barrel 31 is rotated to make the threaded barrel 31 perpendicular to the cover plate 21, and finally the bottom plate 33 is rotated. The bottom plate 33 rotates inside the threaded barrel 31 with the screw rod 32 until the bottom plate 33 is against the ground. The auxiliary device 3 achieves the effect of supporting the cover plate 21, and prevents the cover plate 21 from breaking when heavy objects are placed on it.
[0031] Reference Figure 1-5 As shown, a rubber pad 35 is fixedly connected to one end of the bottom plate 33 away from the screw rod 32, and the size of the rubber pad 35 is adapted to the size of the bottom plate 33. The rubber pad 35 is provided to increase the roughness between the bottom plate 33 and the ground, thereby increasing the friction between the bottom plate 33 and the ground, and preventing the bottom plate 33 and the ground from sliding. A placement groove 34 is provided at the cover plate 21 corresponding to the threaded barrel 31, and the size of the placement groove 34 is larger than the size of the threaded barrel 31. When the desk body 1 is not in use, the threaded barrel 31 is rotated back into the placement groove 34, so as to achieve the effect of storing the threaded barrel 31 and prevent the threaded barrel 31 from affecting the storage of the cover plate 21.
[0032] Working principle: When the desk body 1 is not needed, the two cover plates 21 are moved closer to each other through the groove 28, and the inclined surface 23 of the L-shaped plate 22 on one of the cover plates 21 squeezes the limit buckle 25, the L-shaped plate 22 rotates, and the spring 26 deforms. When the short arm end of the L-shaped plate 22 moves over the limit buckle 25, the L-shaped plate 22 rotates back to its original position under the action of the restoring elastic force of the spring 26, and the limit buckle 25 enters the limit groove 24 of the L-shaped plate 22, thereby achieving the effect of fixing the two cover plates 21. At this time, the two cover plates 21 are stored. When the desk body 1 needs to be used, the L-shaped plate 22 is rotated by the handle 27. The L-shaped plate 22 is inserted into the limit buckle 25 and the limit buckle 25 is removed from the limit groove 24 of the L-shaped plate 22. At this time, the two cover plates 21 are moved away from each other. When the slider 29 abuts against one end of the slide groove 210, the cover plate 21 is stopped from moving. At this time, the threaded cylinder 31 is rotated to remove the threaded cylinder 31 from the placement groove 34 and make it perpendicular to the cover plate 21. Finally, the bottom plate 33 is rotated with the screw 32 inside the threaded cylinder 31 until the bottom plate 33 is against the ground with the help of the rubber pad 35. The auxiliary device 3 achieves the effect of supporting the cover plate 21, and prevents the cover plate 21 from breaking when placing heavy objects. The two cover plates 21 set by the extension device 2 increase the area above the desk body 1, thereby facilitating students to place learning materials and experimental equipment on the cover plate 21, thereby improving the practicality of the desk body 1.
