[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-10 The lifting of the lifting device is to lift the lifting device in a forward direction, and the lifting of the lifting device in a forward direction is to lift the lifting device in a forward direction. The lifting device is a sliding door, and the lifting device is a sliding door. The lifting device is a sliding door, and a front porch, an upper porch, and a rear porch.

[0021] When students are studying in class, they can pull the support rod 8 to drive the frame 5 to slide toward the exit of the storage slot 4. When the ear block 6, the hinge shaft 7 and the support rod 8 are completely moved out of the storage slot 4, the support rod 8 is rotated so that the straight slot 9 rotates accordingly. The horizontal straight slot 9 is rotated and adjusted to a vertical position. At this time, the support rod 8 is slid downward. Since the frame 5 is in the storage slot 4, the positions of the ear block 6 and the hinge shaft 7 are relatively fixed, so that the position of the hinge shaft 7 is in an ascending stage relative to the straight slot 9 and gradually moves toward the oblique slot 10. When the hinge shaft 7 moves to the oblique slot After the student sits in the desk 10, the support rod 8 is guided by the oblique groove 10 and gradually approaches and fits to one side of the desk 1, so that the support rod 8 can be placed upright. At this time, the chest pad 12 is located on the student's side, and the head pad 14 is located directly above the support rod 8. The chest pad 12 provides forward support and a straight leaning reference for the chest area of ​​the student who sits for a long time, and the head pad 14 provides support and limit for the head of the student who sits for a long time, effectively preventing the hunchback problem caused by bending over for a long time due to fatigue when sitting for a long time, thereby achieving the effect of improving the hunchback. During lunch break, the support rod 8 can be slid upward so that the support rod 8 drives the oblique slot 10 and the straight slot 9 to move upward until the hinge shaft 7 is at the end of the straight slot 9. At this time, the support rod 8 is rotated to a horizontal position, and the support rod 8 together with the frame 5 is pushed into the storage slot 4 to complete the folding and storage, so as to prevent the support rod 8, the chest pad 12 and the head pad 14 from interfering with the students' lying on the desk to rest.

[0022] Specifically, in this embodiment, a closing plate slide groove 15 is provided at the opening of the table 1 near the storage slot 4. The length of the closing plate slide groove 15 is twice the length of the storage slot 4. The cross-section of the closing plate slide groove 15 is T-shaped. A closing plate 16 and a handle 17 are slidingly adapted in the closing plate slide groove 15. The closing plate 16 and the handle 17 are connected in a T-shape. The length of the closing plate 16 is the same as the length of the storage slot 4, and the width of the closing plate 16 is greater than the width of the storage slot 4.

[0023] The handle 17 can be used to apply a thrust to the closing plate 16, so that the handle 17 and the closing plate 16 slide in the closing plate slide groove 15. When the closing plate 16 moves to the storage slot 4 for blocking, it can provide a protective effect for the frame 5, support rod 8, chest pad 12 and head pad 14. When the closing plate 16 moves away from the storage slot 4, it can facilitate the removal of the frame 5 together with the support rod 8, and the closing plate slide groove 15 can effectively wrap the closing plate 16 to prevent the closing plate 16 from detaching.

[0024] Specifically, in this embodiment, limiting grooves 18 are provided on both sides of the storage groove 4, the depth of the limiting grooves 18 is less than the depth of the storage groove 4, and a spring 19 is provided on the side of the limiting groove 18 close to the open end of the storage groove 4, and limiting blocks 20 are provided on both sides of the frame 5. The limiting blocks 20 are slidably connected in the limiting grooves 18, and the limiting blocks 20 are connected to the spring 19.

[0025] The cooperation between the limit groove 18 and the limit block 20 can effectively prevent the frame 5 from completely detaching from the storage groove 4, and in the process of the frame 5 moving out of the storage groove 4, the limit block 20 drives the spring 19 to move toward the spring 19, causing the spring 19 to gradually compress. At this time, the elastic force of the compression of the spring 19 prompts the frame 5 to move deeper into the storage groove 4. At this time, the support rod 8 in the vertical state is in the action of the elastic force of the spring 19, and fits more closely with the table 1, thereby further improving the stability of the support rod 8 in the vertical state.

[0026] Specifically, in this embodiment, a rubber pad 21 is provided on one end of the limiting groove 18 away from the spring 19 , and the rubber pad 21 can be in contact with the limiting block 20 .

[0027] The rubber pad 21 is added to provide a buffer for the rapid rebound recovery of the limit block 20 under the elastic force of the spring 19, thereby preventing damage to the connection part caused by impact.

[0028] Specifically, in this embodiment, the frame body 5 is T-shaped, and a folding groove 22 is opened on the belly of the frame body 5. The width of the folding groove 22 is the same as the width of the support rod 8 and corresponds to the space between the two ear blocks 6.

[0029] The T-shaped frame 5 effectively reduces the weight of the frame 5, making it easier for students to pull out the frame 5, and the opening of the folding groove 22 further reduces the weight of the frame 5. At the same time, it provides a partial storage space for the horizontal support rod 8, reducing the total length between the support rod 8 and the frame 5 in the horizontal state, avoiding interference with the closing of the cover plate 16.

[0030] Specifically, in this embodiment, the side of the support rod 8 close to the table 1 is a plane, and the side away from the table 1 is an inclined surface with a gradually decreasing thickness. The straight slot 9 is arranged at the bottom end of the support rod 8, parallel to the plane of the support rod 8, and the inclined slot 10 is arranged at the upper end of the straight slot 9, parallel to the inclined surface of the support rod 8.

[0031] The plane of the support rod 8 fits more closely with the side of the table 1, ensuring the verticality of the support rod 8. The inclined surface effectively reduces the thickness of the end portion, reduces the rotation radius of the support rod 8, and avoids being blocked by the end portion of the frame 5.

[0032] Specifically, in this embodiment, a first locking bolt 23 is internally threadedly connected to a side of the sliding sleeve 11 away from the chest pad 12 , and one end of the threaded section of the first locking bolt 23 can contact the outer wall of the support rod 8 .

[0033] The rotation of the first locking bolt 23 realizes the contact and separation between the end of the threaded section and the support rod 8, thereby achieving the sliding and locking purpose of the sleeve 11 on the support rod 8, and then realizing the height adjustment of the chest pad 12, so that the chest pad 12 can be adaptively adjusted according to the height of the student's chest when sitting down.

[0034] Specifically, in this embodiment, the outer wall of one side of the support rod 8 close to the top end is internally threadedly connected to the second locking bolt 24 , and one end of the threaded section of the second locking bolt 24 can contact the outer wall of the sliding rod 13 .

[0035] The second locking bolt 24 is rotated to realize the contact between the end of the threaded section and the slide rod 13, thereby achieving the sliding and locking purpose of the slide rod 13 in the support rod 8, and then achieving the height adjustment of the head pad 14, so that the head pad 14 can automatically adjust according to the height of the student's head when sitting down. Specifically, in this embodiment, a sponge soft covering layer 25 is provided on the side of the chest pad 12 facing away from the sliding sleeve 11 and on the top of the head pad 14 .

[0036] The sponge soft cover layer 25 is filled with sponge inside and wrapped with leather outside, which can provide cushioning for the student's head and chest, further improving comfort.

[0037] Specifically, in this embodiment, an anti-skid rubber 26 is embedded in the outer wall of the table 1 near the opening of the closing plate sliding groove 15, and the position of the anti-skid rubber 26 corresponds to the position of the support rod 8.

[0038] The addition of the anti-slip rubber 26 provides resistance to the vertical sliding of the support rod 8 in the vertical state, thereby preventing the support rod 8 from sliding vertically under the elastic force of the spring 19 in the vertical state.

[0039] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
