Description

Technical Field

[0001] The utility model relates to the technical field of desks, in particular to a lunch break desk with an adjustable tabletop. Background Art

[0002] An appropriate lunch break can effectively relieve body fatigue. Using the lunch break can better replenish energy and ensure that students can effectively concentrate on studying in the afternoon, thereby effectively improving learning efficiency.

[0003] In the prior art, a Chinese patent with authorization announcement number CN216776443U discloses a tabletop-sunken lunch break desk and chair, comprising a desk and a chair, wherein the desk comprises legs and a tabletop supported on the legs, wherein the height of the tabletop on the legs is adjustable, and the chair comprises legs, a seat panel supported on the legs, and a backrest hinged at the rear end of the seat panel, wherein the height of the seat panel on the legs is also adjustable; the desk and chair can be operated between a study position and a lunch break position, wherein in the study position, the chair is configured to be in a posture suitable for sitting, wherein the tabletop is located above the front end of the seat panel, and in the lunch break position, the seat panel is lifted upward, the backrest is tilted backward, and the tabletop is lowered to the front end of the seat panel. The utility model can be transformed into a structure for students to take a lunch break without moving the position and without occupying additional space, thereby helping students to obtain a comfortable sleeping posture for lunch break, and effectively improving comfort and safety.

[0004] The above-mentioned mechanism adjusts the seat back angle backward and lowers the table top to adjust the desk and chair into a simple bed for nap, thereby realizing the students' nap. However, in actual use, when the seat has a backrest that can be used for lying flat, the seat back will be too high, which will block the students in the back row and affect the learning quality and efficiency of the students in the back row. Therefore, a more appropriate method is to use a desk to fill this part to reduce the obstruction of the students' line of sight caused by the high seat height. At the same time, the traditional desktop angle cannot be adjusted, which will cause discomfort during a nap due to angle mismatch. Utility Model Content

[0005] The utility model aims to provide a lunch break desk with an adjustable tabletop, so as to solve the problem in the above background technology that the angle of the traditional tabletop cannot be adjusted, resulting in discomfort during a nap due to angle mismatch.

[0006] To achieve the above object, the utility model provides the following technical solution: a lunch break desk with an adjustable tabletop, comprising a drawer, the upper end of one end of the drawer is hinged with a table board, both sides of the drawer are fixedly connected to a lower mounting frame, and the interior of the lower mounting frame is fixedly connected to a desk support leg;

[0007] An upper mounting frame is sleeved on the outer side of the desk support leg at the top of the lower mounting frame, and a rest board is fixedly connected to one side between the upper mounting frames, an angle adjustment mechanism for rotating the rest board is arranged inside the upper mounting frame, and a hydraulic rod is fixedly connected to one end inside the upper mounting frame, and the output end of the hydraulic rod is connected to the top inside the upper mounting frame, and the bottom end of the hydraulic rod is connected to the bottom end inside the lower mounting frame, and the rest board is arranged at one end between the table board and the drawer;

[0008] An anti-skid sleeve is provided at one end of the outer side of the desk support leg, and an anti-skid and wear-resistant mechanism for extending the service life is fixedly connected to the bottom end of the anti-skid sleeve.

[0009] Furthermore, the middle positions of both sides of the outside of the drawer are fixedly connected with hanging frames, and the hanging frames are symmetrical with respect to the central axis of the table top in the vertical direction.

[0010] Furthermore, support rods are hinged on both sides of the outer part of the upper mounting frame, and suspension buckles matching the support rods are fixedly connected on both sides of the outer part of the lower mounting frame, guide rods are fixedly connected on both sides of the top end of the rest plate, and fixing rods matching the guide rods are fixedly connected on both sides of the bottom end of the drawer.

[0011] Furthermore, the lower ends of both sides of the table top are fixedly connected to a limiting frame, and a snap-fit ​​mechanism for limiting the table top is provided on the inner side of the limiting frame, the snap-fit ​​mechanism includes a fixing groove, and the fixing groove is opened at the upper ends of both sides of the outside of the drawer, and one side of the limiting frame is fixedly connected to a fixing block matching the fixing groove.

[0012] Furthermore, both sides of the rest board are provided with limiting mechanisms for splicing the rest board, and the limiting mechanism includes a fixing plate, and the fixing plate is fixedly connected to the upper ends of both sides of the outside of the drawer, and a card block is fixedly connected to the inner side of the upper mounting frame, and a card slot matching the card block is opened on one side of the fixing plate.

[0013] Furthermore, the anti-skid and wear-resistant mechanism includes a wear-resistant block, and the wear-resistant block is fixedly connected to the bottom end of the anti-skid sleeve, and the bottom end of the wear-resistant block is fixedly connected with an anti-skid protrusion.

[0014] Furthermore, the anti-slip bumps are distributed at equal angles on the bottom end of the anti-slip sleeve, and the anti-slip bumps are symmetrical about the central axis in the vertical direction of the drawer:

[0015] 1. Since the angles of the table and the rest board can be adjusted, when students place their heads on the rest board, the angle of the rest board can be more in line with the human body, and the students' lunch break can be more comfortable. At the same time, the table and the rest board are adjusted in different directions. After the rest board is adjusted and supported, it can effectively avoid the table board being directly above the student's head after the angle is adjusted, which increases the comfort and safety when taking a lunch break at the desk;

[0016] Furthermore, when the angle of the rest board is adjusted, the hydraulic rods inside the upper mounting frame and the lower mounting frame can play a supporting and adjusting role. The output end of the hydraulic rod pushes the upper mounting frame upward. Since the hydraulic rod is close to the hinge axis, the output end of the hydraulic rod extends a small part to achieve the adjustment of the angle of the rest board.

[0017] Furthermore, after the rest board is supported and adjusted by the hydraulic rod, the support rod is held and moved upward, and the angle of the support rod is adjusted at the same time, so that the support rod can be engaged with the suspension buckle, thereby playing a role in reinforcing the support of the rest board, avoiding the situation that the support angle of the rest board is reduced during the lunch break, and increasing the comfort during the lunch break;

[0018] 2. When resetting the rest board, it is necessary to restore the support rod to its initial position, and then press the rest board downward so that the guide rod slides inside the fixed rod to guide the rest board to reset. At the same time, the card block on the inner side of the upper mounting frame is engaged with the appropriate card slot to achieve a stable connection between the rest board and the drawer, effectively preventing the desk from loosening and shaking in the learning state. At the same time, adjust the table board back to its initial angle so that the fixed block on the inner side of the limit frame under the table board can be engaged with the fixed slot, thereby reinforcing and limiting the position of the table board.

[0019] Furthermore, the anti-slip cover arranged at the bottom end of the desk supporting leg can increase the friction between the desk supporting leg and the ground, thereby avoiding position displacement of the desk supporting leg during use and increasing the stability of the desk supporting leg during use. At the same time, the wear-resistant blocks and anti-slip protrusions at the bottom end of the anti-slip cover can increase the anti-slip and wear-resistant properties of the anti-slip cover itself, effectively extending the service life of the anti-slip cover.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7The technical solution shown is to solve the problem that the angle of the traditional desktop cannot be adjusted, which causes discomfort during a nap due to angle mismatch: the lunch break desk with an adjustable desktop discloses an angle adjustment mechanism, including a drawer 2, the upper end of one end of the drawer 2 is hinged with a table top 1, both sides of the drawer 2 are fixedly connected with a lower mounting frame 7, and the interior of the lower mounting frame 7 is fixedly connected with a desk support leg 3, an upper mounting frame 6 is sleeved on the outer side of the desk support leg 3 at the top of the lower mounting frame 7, and a rest board 4 is fixedly connected to one side between the upper mounting frames 6, an angle adjustment mechanism for rotating the rest board 4 is arranged inside the upper mounting frame 6, and one end of the interior of the upper mounting frame 6 is fixedly connected with a hydraulic Rod 13, and the output end of the hydraulic rod 13 is connected to the top end of the upper mounting frame 6, the bottom end of the hydraulic rod 13 is connected to the bottom end of the lower mounting frame 7, the rest board 4 is arranged at one end between the table board 1 and the drawer 2, and the middle positions on both sides of the outside of the drawer 2 are fixedly connected with the suspension frames 5, and the suspension frames 5 are symmetrical about the vertical center axis of the table board 1, the outer sides of the upper mounting frame 6 are hinged with support rods 8, and the outer sides of the lower mounting frame 7 are fixedly connected with suspension buckles 9 matching the support rods 8, the inner top sides of the rest board 4 are fixedly connected with guide rods 15, and the inner bottom sides of the drawer 2 are fixedly connected with fixed rods 14 matching the guide rods 15.

[0032] In this example, the table top 1 is first rotated so that the rest board 4 under the table top 1 is exposed. Since the angles of the table top 1 and the rest board 4 can be adjusted, when the student places the head on the rest board 4, the angle of the rest board 4 can be more closely fitted to the human body, and the student's lunch break can be more comfortable. At the same time, the table top 1 and the rest board 4 are adjusted in angles in different directions. After the rest board 4 is adjusted and supported, it can effectively avoid the situation where the table top 1 is directly above the student's head after the angle is adjusted, thereby increasing the comfort and safety when taking a lunch break at the desk.

[0033] Embodiment 2:

[0034] like Figure 6 and Figure 8The technical solution shown is to solve the problem of desks shaking and loosening when splicing after lunch break: the lunch break desk with an adjustable desktop discloses a locking mechanism, the lower ends of both sides of the table board 1 are fixedly connected to the limiting frame 16, and the inner side of the limiting frame 16 is provided with a locking mechanism for limiting the table board 1, the locking mechanism includes a fixing groove 18, and the fixing groove 18 is opened at the upper ends of both sides of the outside of the drawer 2, one side of the limiting frame 16 is fixedly connected with a fixing block 17 matching the fixing groove 18, both sides of the rest board 4 are provided with a limiting mechanism for splicing the rest board 4, the limiting mechanism includes a fixing plate 10, and the fixing plate 10 is fixedly connected to the upper ends of both sides of the outside of the drawer 2, the inner side of the upper mounting frame 6 is fixedly connected with a card block 12, and one side of the fixing plate 10 is provided with a card groove 11 matching the card block 12.

[0035] In this example, when resetting the rest board 4, it is necessary to restore the support rod 8 to its initial position, and then press the rest board 4 downward so that the guide rod 15 slides inside the fixed rod 14 to guide the rest board 4 to be reset. At the same time, the block 12 on the inner side of the upper mounting frame 6 is engaged with the appropriate slot 11 to achieve a stable connection between the rest board 4 and the drawer 2, effectively preventing the desk from loosening and shaking in the learning state. At the same time, the table board 1 is adjusted back to its initial angle so that the fixed block 17 on the inner side of the limit frame 16 below the table board 1 can be engaged with the fixed slot 18, thereby reinforcing and limiting the position of the table board 1.

[0036] Embodiment three:

[0037] like Figure 7 The technical solution shown is to solve the problem that the desk support leg 3 is easily displaced due to collision during use: the lunch break desk with an adjustable tabletop discloses an anti-slip mechanism, an anti-slip sleeve 19 is provided on one end of the outer side of the desk support leg 3, and the bottom end of the anti-slip sleeve 19 is fixedly connected with an anti-slip and wear-resistant mechanism for extending the service life, the anti-slip and wear-resistant mechanism includes a wear-resistant block 20, and the wear-resistant block 20 is fixedly connected to the bottom end of the anti-slip sleeve 19, the bottom end of the wear-resistant block 20 is fixedly connected with an anti-slip protrusion 21, the anti-slip protrusions 21 are distributed at equal angles on the bottom end of the anti-slip sleeve 19, and the anti-slip protrusions 21 are symmetrical about the vertical center axis of the drawer 2.

[0038] In this example, the anti-slip cover 19 mounted on the bottom end of the desk supporting leg 3 can increase the friction between the desk supporting leg 3 and the ground, thereby avoiding position displacement of the desk supporting leg 3 during use and increasing the stability of the desk supporting leg 3 during use. At the same time, the wear-resistant block 20 and the anti-slip protrusion 21 at the bottom end of the anti-slip cover 19 can increase the anti-slip performance and anti-wear performance of the anti-slip cover 19 itself, thereby effectively extending the service life of the anti-slip cover 19.
