[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-5 This utility model provides a technical solution:

[0024] An adjustable mattress compression device includes a frame body 1, a pressure plate 2 slidably connected inside the frame body 1, and adjustment components 3 at both ends inside the pressure plate 2.

[0025] The adjusting component 3 is used to adjust the length of the pressure plate 2. The adjusting component 3 consists of a connecting frame 4, an extension plate 5, a movable frame 6, two sets of rotating rods 7 and a fixed rod 8. The connecting frame 4 is fixedly connected to the top of the pressure plate 2. The extension plate 5 is slidably connected to the inside of the connecting frame 4. The movable frame 6 is located above the extension plate 5 and is slidably connected to the inside of the connecting frame 4. The two sets of rotating rods 7 are rotatably connected to both ends inside the movable frame 6, and the fixed rod 8 is rotatably connected to the outside of the rotating rods 7.

[0026] Furthermore, sliding grooves 9 are provided inside the connecting frame 4 and inside the movable frame 6. The movable frame 6 and the sliding grooves 9 are slidably connected. Two sets of bidirectional cylinders are fixedly connected inside the connecting frame 4 and between the two sets of movable frames 6. The two ends of the bidirectional cylinders are fixedly connected to the two sets of movable frames 6 respectively. The end of the fixed rod 8 away from the rotating rod 7 is fixedly connected to the extension plate 5, which slidably connects the movable frame 6 to the sliding grooves 9. When the movable frame 6 moves, it can be guided by the sliding grooves 9 to prevent deviation. The bidirectional cylinders are activated to drive the two sets of movable frames 6 to move, so that the rotating rod 7 can move, which drives the fixed rod 8 to move, thereby causing the extension plate 5 to move.

[0027] Secondly, guide grooves 10 are provided inside the connecting frame 4 and at both ends of the extension plate 5. The extension plate 5 extends into the guide groove 10 and is fixedly connected to the guide post 11. The guide post 11 and the guide groove 10 are slidably connected. When the extension plate 5 moves, it drives the guide post 11 to move. When the guide post 11 moves to the front end of the guide groove 10, it causes the moving groove to move downward and be on the same horizontal plane as the pressure plate 2.

[0028] Furthermore, a receiving groove 12 is provided at the front end of the guide groove 10. A limiting rod 13 is rotatably connected to the front end of the receiving groove 12. A connecting rod 14 is fixedly connected to the outer side of the limiting rod 13. The connecting rod 14 extends to the outer side of the connecting frame 4 and is fixedly connected to a limiting gear 15. A limiting block 16 is provided at the bottom of the limiting gear 15. A damping spring 17 is fixedly connected to the end of the limiting block 16 away from the limiting gear 15. The end of the damping spring 17 away from the limiting block 16 is fixedly connected to the connecting frame 4 through a connecting seat 18. The limiting block 16 and the connecting seat 18 are slidably connected. A limiting groove 19 is provided at the top of the connecting seat 18. The limiting groove 19 contains... Both ends of the part are fixedly connected with elastic protrusions. A pull rod 20 is fixedly connected to the outside of the limiting block 16. Pulling the pull rod 20 moves it to the inside of the limiting groove 19. The pull rod 20 is limited to the inside of the limiting groove 19 by two sets of elastic protrusions, so that the connection between the limiting block 16 and the limiting gear 15 is disconnected, so that the limiting gear 15 can rotate. The limiting rod 13 is not limited by the connecting rod 14, so that the limiting rod 13 can rotate. The moving frame 6 is reset a certain distance, so that the extension plate 5 moves towards the pressure plate 2 and contacts the limiting rod 13, driving the limiting rod 13 to rotate, so that it moves into the inside of the receiving groove 12.

[0029] Furthermore, the inner side of the extension plate 5 has multiple sets of snap-fit ​​grooves, and both ends of the pressure plate 2 are fixedly connected to multiple sets of snap-fit ​​posts 21. The pressure plate 2 is limited to the snap-fit ​​grooves through the snap-fit ​​posts 21. When the guide post 11 moves into the interior of the receiving groove 12, the snap-fit ​​post 21 is limited to the snap-fit ​​groove, thereby limiting the connection between the extension plate 5 and the pressure plate 2. This allows the length of the pressure plate 2 to be extended. The length of the pressure plate 2 is automatically adjusted according to the size of the mattress, and the appropriate size is used for compression packaging. During the compression process, the mattress is fully covered, and the sealing is not affected after compression. When it is necessary to move the extension plate 5 to... When the connecting frame 4 is inside, the guide post 11 is moved to the outside of the receiving groove 12, so that it is moved into the inside of the guide groove 10. At the same time, the limiting rod 13 is rotated, so that the limiting rod 13 is designed with an oblique structure. The pull rod 20 is moved out from the inside of the limiting groove 19. The limiting block 16 is moved by the damping spring 17 and connected with the limiting gear 15. The connecting rod 14 limits the limiting rod 13. The reset moving frame 6 drives the extension plate 5 to reset. The guide post 11 can be reset to the rear end of the guide groove 10 by the oblique limiting rod 13, so that the extension plate 5 is reset into the inside of the connecting frame 4.

[0030] In this embodiment, the specific implementation scenario is as follows: During actual use, the bidirectional cylinder is activated, causing the two sets of moving frames 6 to shift, which in turn causes the rotating rod 7 to shift, thereby causing the fixed rod 8 to shift, which in turn causes the extension plate 5 to shift. When the extension plate 5 shifts, it causes the guide column 11 to shift. When the guide column 11 shifts to the front end of the guide groove 10, the moving groove shifts downward, becoming level with the pressure plate 2, pulling the pull rod 20 to shift into the interior of the limiting groove 19. The pull rod 20 is then limited by two sets of elastic protrusions. Inside the limiting groove 19, the connection between the limiting block 16 and the limiting gear 15 is broken, allowing the limiting gear 15 to rotate. This removes the limiting rod 13 from the limiting rod 14, allowing the limiting rod 13 to rotate. The moving frame 6 is reset a certain distance, causing the extension plate 5 to move towards the pressure plate 2 and contact the limiting rod 13, thus rotating the limiting rod 13 and displacing it inside the receiving groove 12. When the guide post 11 moves into the receiving groove 12, the locking post 21 is connected to the locking groove for a limiting connection. This allows the extension plate 5 to be connected to the pressure plate 2, thus extending the length of the pressure plate 2. The length of the pressure plate 2 is automatically adjusted according to the size of the mattress, and the appropriate size is used for compression packaging. During the compression process, the mattress is fully covered, and the sealing is not affected after compression. When it is necessary to move the extension plate 5 to the inside of the connecting frame 4, the guide post 11 is moved to the outside of the receiving groove 12, so that it is moved into the inside of the guide groove 10. At the same time, the limiting rod 13 is rotated, so that the limiting rod 13 has an oblique structure design. The pull rod 20 is moved out from the inside of the limiting groove 19, and the limiting block 16 is moved by the damping spring 17, and is connected to the limiting gear 15. The connecting rod 14 limits the limiting rod 13. The reset moving frame 6 drives the extension plate 5 to reset. The guide post 11 can be reset to the rear end of the guide groove 10 through the oblique limiting rod 13, so that the extension plate 5 is reset into the inside of the connecting frame 4. Compared with the existing compression device, this utility model can improve the overall practicality of the compression device through design.
