[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a height-adjustable mattress frame, including a bed frame 1. A limiting block 2 is fixedly connected inside the bed frame 1, serving to limit the position. Support plates 3 are fixedly connected to both sides of the limiting block 2, providing support for the support plates 3. Three connecting plates 4 are fixedly connected to adjacent sides of the two support plates 3, providing support for the upper connecting plate 4 and ensuring its stability. A second limiting block 5 is fixedly connected to one side of each of the three connecting plates 4. An electric push rod 6 is rotatably connected inside the second limiting block 5, allowing the electric push rod 6 to be activated after being moved. The limit block 2 5 provides support for the electric push rod 6 to work normally. The internal rotatable connection of the limit block 2 5 is a threaded pin 16, which is used to fix the bottom position of the electric push rod 6 so that it will not be displaced during operation, ensuring that the electric push rod 6 can function stably. The outside of the threaded pin 16 contacts the bottom of the electric push rod 6. Through this contact connection, the electric push rod 6 is firmly fixed to the limit block 2 5. The end of the electric push rod 6 away from the limit block 2 5 is fixedly connected to a fixing ring 7. The electric push rod 6 provides support for the fixing ring 7. The fixing ring 7 will move with the extension and retraction of the electric push rod 6. The internal rotatable connection of the fixing ring 7 is a threaded pin 17.

[0034] A fixing block 8 is rotatably connected to the outside of the fixing ring 7. A threaded pin 17 is rotatably connected to the fixing ring 7. When the electric push rod 6 moves the fixing ring 7, the threaded pin 17 rotates accordingly, thereby moving the fixing block 8. The fixing block 8 moves along with the fixing ring 7 under the action of the threaded pin 17. A support plate 9 is fixedly connected to the top of the fixing block 8. The support plate 9 moves under the push of the fixing block 8, thereby changing the height of one end of the mattress to facilitate the placement of the user's feet and provide comfortable support. The two ends of the support plate 29 are fixedly connected to the limiting frame 10. The limiting frame 10 moves with the support plate 29 to help adjust the height of one end of the mattress. The top of the side of the limiting block 12 away from the limiting frame 10 contacts the limiting frame 4 13. The limiting frame 4 13 is fixedly connected to the support plate 3 14. The limiting frame 4 13 provides the installation and support position for the support plate 3 14. The support plate 3 14 rotates under the action of the electric push rod 6, thereby lifting the other end of the mattress, making it convenient for the user to lie down with the upper part of their body, and providing the user with a comfortable lying angle.

[0035] One of the fixing blocks 18 has its top in contact with the bottom of the support plate 3 14. This allows the support plate 3 14 to rotate when the fixing block 18 moves, thus adjusting the height of the other end of the mattress. A limiting component is fixedly connected to the top of the limiting frame 4 13. Three connecting plates 2 15 are fixedly connected to the top inner side of the limiting frame 4 13. The connecting plates 2 15 connect and fix the limiting frame 4 13 to the support plate 3 14, enhancing the structural stability. The bottom of the connecting plates 2 15 contacts the top of the support plate 3 14. This contact connection allows the mattress to be adjusted. The second connecting plate 15 better performs its fixing and connecting functions. The limiting component includes a first limiting device 21, which restricts the movement of the mattress in this position to ensure the stability of the mattress. The top of the first limiting frame 10 is fixedly connected to a second limiting device 22, which also plays a limiting role for the mattress. Together with the first limiting device 21, they ensure that the mattress will not move arbitrarily during use. The bottom of the first limiting device 21 is fixedly connected to the top of the fourth limiting frame 13, and the first limiting device 21 will rotate as the fourth limiting frame 13 rotates.

[0036] Reference Figure 1 , Figure 4 and Figure 5 Limiting block 12 is fixedly connected to the top of limiting frame 3 12, which provides support. A fixing pin 23 is threadedly connected to the top of limiting frame 3 12, securing the limiting frame 3 12 and support plate 1 3 together to ensure the limiting frame 3 12 does not loosen during use. Two limiting blocks 3 18 are fixedly connected to both sides of the limiting frame 3 12. A fixing block 2 20 is rotatably connected to the outside of the connecting pin 19. The limiting blocks 3 18 connect and rotate the fixing blocks 2 20, providing a rotational support point for the fixing blocks 2 20. A connecting pin 19 is rotatably connected inside the limiting blocks 3 18, connecting the limiting blocks 3 18 and the fixing blocks 2 20 together, ensuring the limiting blocks 3 18 and the fixing blocks 2 20 are securely connected. Fixed block 20 can rotate relative to each other, realizing flexible connection between the limiting frames. Fixed block 20 is fixedly connected to limiting frame 21 on the side away from limiting frame 3 12. The output end of one of the electric push rods 6 is rotatably connected to the bottom of limiting frame 21. Under the action of electric push rod 6, one side of limiting frame 21 can be lifted up, which is convenient for the user's leg placement and provides comfortable support for the user. The bottom of limiting frame 21 contacts the top of limiting block 1 2. This contact method makes limiting frame 21 more stable under the support of limiting block 1 2. The bottom of the fixing nail 23 is threadedly connected to the inside of support plate 1 3. Through this threaded connection method, limiting frame 3 12 is firmly fixed to support plate 1 3, ensuring the stability of the entire frame structure.

[0037] This structural design allows the entire adjustable mattress frame to flexibly adjust the height of different parts of the mattress according to the user's needs, providing a comfortable lying experience. Moreover, the connection points of the limiting frames 10, 11, 12, and 13 are all completed by the combination of limiting block 3 18 and fixing block 20, and then connected by threaded nails 19. This connection method makes the frame structure both stable and easy to disassemble and assemble. The fixing nails 23 fix the limiting frame 3 12 and the support plate 3 through threaded connection. The threaded nails 2 17 connected to the output end of the electric push rod 6 and the threaded nails 1 16 connected to the bottom are both fixed by threaded connection. After part of the frame is damaged, it can be replaced according to the damaged part, which improves the efficiency of material use, reduces maintenance costs, and extends the service life of the entire adjustable mattress frame.

[0038] Working principle: First, the mattress is placed on the frame. Then, the electric push rod 6 can be activated according to the user's habits. The output end of one of the electric push rods 6 will drive the fixed ring 7 to move. The movement of the fixed ring 7 will drive the threaded pin 17 to rotate. The rotation of the threaded pin 17 will drive the fixed block 8 to move. The movement of the fixed block 8 will push the support plate 9 to move. The movement of the support plate 9 will drive the limiting frame 10 to move, realizing the height adjustment of one end of the mattress, which will facilitate the placement of the user's feet. Since the bottom of the limiting frame 12 is fixed to the top of the support plate 3, one of the electric push rods 6 near the limiting frame 13 will push the support plate 14 to rotate after activation. Then, the other end of the mattress will be lifted, which will facilitate the upper body of the user to lie down. One of the electric push rods 6 will push one side of the limiting frame 11 after activation. Then, the output end of the electric push rod 6 can lift one side of the limiting frame 11, which will facilitate the placement of the user's legs, thereby improving the flexibility of the device.

[0039] The connection points of limit frame 10, limit frame 21, limit frame 312 and limit frame 413 are all completed by the combination of limit block 318 and fixing block 20 and then the connection pin 19 is threaded together. The fixing pin 23 fixes limit frame 312 and support plate 13 through threaded connection. The threaded pin 217 connected to the output end of electric push rod 6 and the threaded pin 16 connected to the bottom are both threaded and fixed. After part of the frame is damaged, it can be replaced according to the damaged part, which improves the efficiency of material use.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
