Detailed Implementation

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] A convertible desk for different teaching modes; please refer to [link / reference]. Figures 1-10 The table includes a table box 10 with openings at the top and rear, a tabletop 12 at the top of the table box 10, and a support frame for supporting the table box 10. The tabletop 12 is hinged to the table box 10 near the rear opening so that the tabletop 12 can rotate along the table box 10. The table box 10 is provided with at least two telescopic and adjustable support components located inside the table box 10 near the front. In this application, two support components are preferred.

[0029] See Figure 1 and Figure 2 The tabletop 12 has a horizontal state and an inclined state; when the tabletop 12 is in the inclined state, the support assembly can support the tabletop 12.

[0030] Specifically, the support assembly includes a first sleeve rod 50, a second sleeve rod 51, a lifting rod 52, a second locking bolt 55, and a third locking bolt 56. The first sleeve rod 50 is fixedly installed inside the table case 10, and the bottom end of the first sleeve rod 50 is fixedly connected to the bottom inner wall of the table case 10.

[0031] The second sleeve rod 51 is slidably sleeved on the outside of the lifting rod 52. Specifically, the top of the second sleeve rod 51 is provided with a second receiving groove, and the lifting rod 52 is slidably inserted into the second receiving groove. The top of the second sleeve rod 51 is fixedly connected to a limiting platform 510, which is also provided with a through groove that matches the opening of the second receiving groove, allowing the lifting rod 52 to pass through. The third locking bolt 56 is used to lock the second sleeve rod 51 and the lifting rod 52. The side wall of the limiting platform 510 is provided with a third threaded groove that communicates with the through groove. The third locking bolt 56 is threadedly connected to the third threaded groove. Tightening the third locking bolt 56 so that its end abuts against the lifting rod 52 can lock the lifting rod 52 onto the second sleeve rod 51.

[0032] The first sleeve rod 50 is slidably sleeved outside the second sleeve rod 51. The second locking bolt 55 is used to lock the second sleeve rod 51 and the first sleeve rod 50. Similarly, the top of the first sleeve rod 50 is provided with a first receiving groove, and the second sleeve rod 51 is slidably inserted into the first receiving groove. The side wall of the first sleeve rod 50 is provided with a second threaded groove communicating with the first receiving groove. The second locking bolt 55 is threadedly connected to the second threaded groove. Tightening the second locking bolt 55 so that its end abuts against the second sleeve rod 51 can lock the second sleeve rod 51 onto the first sleeve rod 50.

[0033] A rubber plate 53 is fixedly connected to the top of the lifting rod 52. The top surface of the rubber plate 53 is inclined, and the inclination direction of the top surface of the rubber plate 53 is the same as the inclination direction of the table 12. Several rubber protrusions 54 are provided on the top surface of the rubber plate 53. The rubber protrusions 54 and the rubber plate 53 are an integral structure. The inclination of the top surface of the rubber plate 53 makes it easier to better abut against the table when it is in an inclined state. The rubber protrusions 54 can more easily contact the bottom of the table when it is in an inclined state.

[0034] For example, during a painting class, students can lift the tabletop 12 from the front to tilt it at a certain angle as needed. Then, they can first extend the second rod 51 of the support assembly and tighten the second locking bolt 55. Next, they can extend the lifting rod 52 so that the rubber ball 54 at its top abuts against the bottom of the tabletop. Then, they can tighten the third locking bolt 56. At this time, the tabletop 12 can be kept tilted.

[0035] When it is necessary to place the tabletop in a horizontal position for academic classes, the tabletop 12 can be lifted to a greater angle. Then, the third locking bolt 56 and the second locking bolt 55 can be loosened in sequence. The lifting rod 52 and the second sleeve rod 51 can be retracted. Then, the tabletop 12 can be slowly lowered to keep it in a horizontal position.

[0036] Therefore, it can be seen that the desk in this utility model can be adjusted to a horizontal or tilted state according to the needs of different teaching modes, which is more practical than the existing desks whose desks can only be placed horizontally.

[0037] When the tabletop 12 is used in an inclined state, it is not easy to place items on it. In order to solve this technical problem, this application provides a shelf 40 that can slide along the length of the table box 10 inside the table box 10. When the tabletop 12 is in a horizontal state, the shelf 40 is pressed down. When the tabletop 12 is in an inclined state, a part of the shelf 40 can slide out of the table box 10. By sliding a part of the shelf 40 out, it can be used to place items.

[0038] For details, please refer to Figure 3 , Figure 5 , Figure 7 A flat plate 42 is fixedly installed inside the table box 10. The two ends of the flat plate 42 are fixedly connected to the two sides of the inner wall of the table box 10. A through groove 100 is provided at both ends of the flat plate 42 on the table box 10. The bottom of the through groove 100 is at the same height as the top of the flat plate 42. A first sliding groove 420 is provided at the top of the top of the flat plate 42. A second sliding groove 101 is provided at the bottom of the through groove 100. The second sliding groove 101 is connected to the first sliding groove 420. A slider 410 is fixedly connected to the bottom of the shelf 40. The slider 410 is slidably connected to both the second sliding groove 101 and the first sliding groove 420.

[0039] The top height of the shelf 40 is the same as the top height of the table box 10; when the table 12 is placed horizontally, the bottom of the table 12 can press on the shelf 40, making it less likely for the shelf 40 to slide.

[0040] See Figure 1 , Figure 9 , Figure 10 When the tabletop 12 is used in an inclined state, such as during a painting class, in order to prevent the drawing paper placed on the tabletop 12 from falling, this application has a strip seat 60 fixedly connected to the rear side of the tabletop 12. The front and top openings of the strip seat 60 form an insertion slot 600. A strip 61 is inserted into the insertion slot 600. The strip 61 has a certain friction with the insertion slot 600, and it is necessary to apply force to pull the strip 61. A pull plate 62 is fixedly provided on the top of the strip 61. When the strip 61 is fully inserted into the insertion slot 600, the top of the pull plate 62 is flush with the top of the tabletop 12. When the tabletop 12 is used in a horizontal state, the top of the pull plate 62 is flush with the top of the tabletop 12 for the convenience of students.

[0041] It is worth noting that a groove 610 is provided on the rear side of the strip 61, and a limiting block 601 is fixed on the upper part of the inner wall of the socket 600. The limiting block 601 is located in the groove 610. When the strip 61 is pulled upward from the socket 600, the limiting block 601 and the groove 610 cooperate to limit the strip 61, preventing it from slipping out of the socket 600. When the strip 61 is pulled up, it can provide some protection to the inclined bottom (rear side) of the table, effectively preventing the drawing paper placed on the table 12 from falling.

[0042] The support frame includes two table legs 21, with two support rods 20 fixedly connected to the top of the table legs 21, and a connecting rod 22 fixedly connected between the support rods 20 on the front side of the two table legs 21.

[0043] The bottom of the table box 10 is provided with extension plates 11 on both sides, and the bottom of the extension plates 11 is provided with two slots 110. Two support rods 20 located on the same table leg 21 are slidably inserted into the two slots 110 of the same extension plate 11. The table box 10 also includes a first locking bolt 3 for locking the support rods 20 into the slots 110. Specifically, the side wall of the extension plate 11 is provided with a number of equally spaced through holes 111 along the height direction. The through holes 111 communicate with the slots 110. The support rods 20 are provided with a number of equally spaced threaded holes 200 along their length direction. The distance between two adjacent threaded holes 200 is equal to the distance between two adjacent through holes 111. When the support rods 20 are slidably inserted into the slots 110, at least one of the threaded holes 200 is ensured to correspond to the through hole 111, so that the first locking bolt 3 passes through the through hole 111 and is threadedly connected to the threaded hole 200, thereby locking the support rods 20.
