[0035] Reference below Figure 1-Figure 5 The desk panel sliding backward structure according to the embodiment of the utility model is described.

[0036] like Figure 1-Figure 5As shown, the desk panel sliding backward structure is applied in the desk, and the desk includes a table leg 100, a table leg support frame 200 and a table drawer 300, one end of the table leg support frame 200 is connected to the table leg 100, and the other end is connected to the table drawer 300. The desk panel sliding backward structure of the utility model can make the table drawer 300 and the table leg support frame 200 slide relative to each other, so as to adjust the front and rear distance of the table drawer 300. During the lunch break, the table drawer 300 moves backward to make more space for the front row, and the angle of the front seat backrest is increased, so as to obtain a better lunch break posture and nap space, which is conducive to improving the sleep quality and effectively improving the quality of students' afternoon classes, and making them more focused.

[0037] Specifically, the desk panel backward sliding structure includes a guide seat 210, a sliding frame 310 and an unlocking assembly 220. The guide seat 210 is fixedly arranged on the table leg support frame 200, and a guide groove 211 is formed through the middle of the guide seat 210. The sliding frame 310 is fixedly connected to the table drawer 300, and the sliding frame 310 is slidably connected to the guide seat 210 and reciprocates along the setting direction of the guide groove 211. The sliding frame 310 slides synchronously with the table drawer 300, and the position of the table drawer 300 on the table leg support frame 200 is changed by adjusting the distance of the sliding frame 310 in the guide seat 210.

[0038] The unlocking component 220 is arranged in the table leg support frame 200, and is located on one side of the guide seat 210. One end of the unlocking component 220 extends into the guide groove 211 and abuts against the sliding frame 310. The unlocking component 220 is used to lock and unlock the sliding frame 310. After adjusting the position of the table drawer 300, the position of the table drawer 300 and the table leg support frame 200 is locked by the unlocking component 220 to prevent the table drawer 300 from sliding and ensure safety during sleep. After the lunch break is over, the table drawer 300 is unlocked by the unlocking component 220 and pushed to reset, so that students can quickly enter the learning state.

[0039] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the sliding frame 310 is in a U-shaped structure, and both ends of the sliding frame 310 are respectively slidably connected to the guide seat 210. Specifically, the sliding frame 310 surrounds the periphery of the table drawer 300 and is fixedly connected to the side wall of the table drawer 300, and both sides of the sliding frame 310 slide with the guide seat 210 respectively, which can effectively improve the sliding smoothness of the table drawer 300 and make it easier to adjust the position of the table drawer 300.

[0040] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the cross-sectional profile of the sliding frame 310 matches the cross-sectional profile of the guide groove 211. Specifically, in this embodiment, the sliding frame 310 adopts a square tube structure, and correspondingly, the guide groove 211 is a square groove.

[0041] It should be understood that the square structure of the sliding frame 310 and the guide groove 211 is not the only embodiment. In some other embodiments, a round tube structure or an elliptical tube structure can also be used according to actual production requirements. The utility model does not elaborate on the contour structure of the sliding frame 310 and the guide groove 211. It should be understood that the flexible transformation of the contour structure of the sliding frame 310 and the guide groove 211 without departing from the basic concept of the utility model should be regarded as within the protection scope defined by the utility model.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a limiting groove 212 is provided on one side of the guide seat 210 near the inside of the table bucket 300, and a limiting beam 320 is provided on the table bucket 300. The limiting beam 320 slides synchronously with the table bucket 300, and the table bucket 300 slides synchronously with the sliding frame 310. The two ends of the limiting beam 320 are respectively provided in the limiting groove 212. When the limiting beam 320 abuts against the end of the limiting groove 212, the table bucket 300 reaches the limit sliding distance. Specifically, when the table bucket 300 moves, the two ends of the limiting beam 320 slide synchronously on the limiting grooves 212 of the two guide seats 210. The limiting beam 320 can also play a role in enhancing the structural strength of the table bucket 300.

[0043] In a further embodiment, Figure 1 As shown, a panel 330 is fixed above the table 300, and the limiting beam 320 is located below the panel 330. Specifically, the panel 330 covers the limiting beam 320, which can hide the structural position of the limiting beam 320, improve the structural strength of the panel 330, and enhance the anti-deformation ability of the panel 330.

[0044] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the unlocking assembly 220 includes an elastic stopper 221 and an unlocking lever 223. One end of the elastic stopper 221 is rotatably connected to the table leg support frame 200, and the other end extends into the guide seat 210 and abuts against the side wall of the sliding frame 310. The unlocking lever 223 is rotatably connected to the table leg support frame 200, and the end of the unlocking lever 223 abuts against the elastic stopper 221. The unlocking lever 223 is used to control the elastic stopper 221 to contact or separate from the sliding frame 310.

[0045] Specifically, the elastic limiting member 221 is mainly responsible for unlocking or locking the position of the table bucket 300 and the table leg support frame 200 , and the unlocking lever 223 is mainly used to drive the elastic limiting member 221 to change the working state of the elastic limiting member 221 .

[0046] In a further embodiment, Figure 4 and Figure 5As shown, a locking groove 311 is provided on the side wall of the sliding frame 310, and one end of the elastic limiting member 221 can be detachably engaged with the locking groove 311. When the elastic limiting member 221 is engaged with the locking groove 311, the positions of the table drawer 300 and the table leg support frame 200 are relatively fixed. When the elastic limiting member 221 is separated from the locking groove 311, the positions of the table drawer 300 and the table leg support frame 200 slide relatively.

[0047] Specifically, when the elastic limiting member 221 is separated from the locking groove 311 , the elastic limiting member 221 is away from the side wall of the sliding frame 310 , and the sliding frame 310 can move forward and backward.

[0048] In a further embodiment, Figure 4 and Figure 5 As shown, a reset elastic member 222 is provided in the middle of the elastic stopper 221, and the reset elastic member 222 is used to push the elastic stopper 221 to separate from the locking groove 311. When the locking groove 311 of the sliding frame 310 slides to the position of the elastic stopper 221, the sliding frame 310 can slide freely in the guide groove 211 because the reset elastic member 222 continuously pushes the elastic stopper 221 away from the sliding frame 310. When the unlocking lever 223 locks the elastic stopper 221, the reset elastic member 222 is in a compressed state, and the end of the elastic stopper 221 abuts against the side wall of the sliding frame 310 until the end of the elastic stopper 221 is aligned with the locking groove 311 and embedded in the locking groove 311, thereby completing the reset of the table drawer 300.

[0049] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the unlocking lever 223 includes a cam portion 223-1 and a lever portion 223-2. The cam portion 223-1 is rotatably connected to the table leg support frame 200, and the lever portion 223-2 extends to the outside of the table leg support frame 200. When the lever portion 223-2 is in a locked state, the cam portion 223-1 pushes the elastic limiting member 221 to engage with the locking groove 311. When the lever portion 223-2 is in an unlocked state, the reset elastic member 222 pushes the elastic limiting member 221 to separate from the locking groove 311.

[0050] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the table leg support frame 200 is provided with a receiving groove 201, and when the unlocking lever 223 is in a locked state, the lever portion 223-2 is located in the receiving groove 201. Specifically, when the lever portion 223-2 is located in the receiving groove 201, the contour of the lever portion 223-2 matches the surface contour of the table leg support frame 200, so that the surface integrity of the table leg support frame 200 is more complete.
