[0026] EMBODIMENT

[0027] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the technical scheme in the embodiment of the application effectively solves the technical problem that with the increase of grades, books and stationery increase, the requirement for desk space increases, the desk surface is still fixed in area, the desk surface space is limited, students may not have enough space to place arms and books when writing, leading to unnatural writing posture, affecting the progress of writing and reading, and the overall idea is as follows:

[0028] The utility model provides a student can extend desk, including desktop body 11, the both sides of desktop body 11 are slidably installed with expansion assembly, every expansion assembly includes support plate 12, backing plate 18, reset rod 19 and extension slide 21, and the side end of every extension slide 21 is provided with at least two locking rods 22 with the butt joint of desktop body 11, and every reset rod 19 is vertically installed with reset spring inside, and the side end of every extension slide 21 is slidably connected with support plate 12, by pulling support plate 12, let support plate 12 slide in the side end of desktop body 11, support plate 12 drives extension slide 21 to slide simultaneously, let extension slide 21 slide out the side end of desktop body 11, under the force of reset rod 19, reset rod 19 generates the upward thrust to extension slide 21, let extension slide 21 short distance slide up and be flush with the top end of support plate 12, and simultaneously under the reverse effect of elastic telescopic rod 17, elastic telescopic rod 17 drives support plate 12 to move reversely, let the multiple locking rods 22 of extension slide 21 side end insert the side end of desktop body 11, and support and fix extension slide 21, and the position of support plate 12 is fixed, by the sliding of support plate 12 to extend the desktop of desk, let students can adjust the desktop area according to own demand, satisfy the learning demand of individualization,

[0029] By extending, splicing and the like, the area of the desktop body 11 is extended, so that students can conveniently place data and share achievements when having group discussion or project cooperation, and the communication and cooperation among students are promoted.

[0030] The side end of the support plate 12 is fixedly installed with a reinforcing plate 16 butt-jointed with the desktop body 11, and at least two elastic telescopic rods 17 are fixedly installed at the side end of each reinforcing plate 16, and the other end of each elastic telescopic rod 17 is fixedly connected with the inside of the desktop body 11, by pulling the support plate 12 to move, the reinforcing plate 16 slides at the side end of the desktop body 11, the support plate 12 is guided and supported by the reinforcing plate 16, and the pressure is shared, and the support plate 12 is reversely forced by the elastic telescopic rod 17 after being stretched, and the support plate 12 is automatically pulled to slide at the side end of the desktop body 11.

[0031] Both side ends of each desktop body 11 are provided with at least two positioning holes, the side end of each desktop body 11 is provided with a receiving groove 14 for docking with the expansion slide plate 21, and the two side ends of each desktop body 11 are provided with a guide groove 15 for slidingly docking with the reinforcing plate 16. By pressing the expansion slide plate 21, the expansion slide plate 21 is slid downward to align with the side end of the receiving groove 14. Under the reverse tension generated by the elastic expansion rod 17, the supporting plate 12 slides to the side end of the desktop body 11. The expansion slide plate 21 slides into the inside of the receiving groove 14, and the reinforcing plate 16 slides into the inside of the guide groove 15. The expansion slide plate 21 and the reinforcing plate 16 are hidden in the inside of the desktop body 11, which is convenient for unfolding and storage, and reduces the volume.

[0032] The two side ends of each desktop body 11 are rotatably provided with two rotary buckles 13. By rotating the rotary buckle 13, the end of the rotary buckle 13 is screw designed, and the rotary buckle 13 is extruded and fixed to the reinforcing plate 16 to fasten the position of the reinforcing plate 16.

[0033] Working principle:

[0034] First step, by pulling the supporting plate 12, the supporting plate 12 slides to the side end of the desktop body 11. The reinforcing plate 16 plays a guiding and supporting role for the supporting plate 12, and shares the pressure. At the same time, the elastic expansion rod 17 generates a reverse force on the supporting plate 12 after stretching, and automatically pulls the supporting plate 12 to slide to the side end of the desktop body 11. The supporting plate 12 drives the expansion slide plate 21 to slide at the same time, and the expansion slide plate 21 slides out of the side end of the desktop body 11. Under the action of the reset rod 19, the reset rod 19 generates an upward thrust on the expansion slide plate 21, and the expansion slide plate 21 slides upward by a short distance to be flush with the top end of the supporting plate 12. At the same time, under the reverse action of the elastic expansion rod 17, the elastic expansion rod 17 drives the supporting plate 12 to move reversely, and the multiple locking rods 22 at the side end of the expansion slide plate 21 are inserted into the side end of the desktop body 11 to support and fix the expansion slide plate 21, and fix the position of the supporting plate 12. By sliding the supporting plate 12 to extend the desktop, students can adjust the desktop area according to their own needs to meet the personalized learning needs.

[0035] Second step, by pressing the expansion slide plate 21, the expansion slide plate 21 is slid downward to align with the side end of the receiving groove 14. Under the reverse tension generated by the elastic expansion rod 17, the supporting plate 12 slides to the side end of the desktop body 11. The expansion slide plate 21 slides into the inside of the receiving groove 14, and the reinforcing plate 16 slides into the inside of the guide groove 15. The expansion slide plate 21 and the reinforcing plate 16 are hidden in the inside of the desktop body 11, which is convenient for unfolding and storage, and reduces the volume.

[0036] Finally, it should be noted that: apparently, the above embodiments are merely examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
