Description

Technical Field

[0001] This utility model relates to the field of medical nursing bed technology, and in particular to a docking and interlocking structure for a bunk bed frame. Background Technology

[0002] Conventional sub-bed and parent-bed structures are connected via snap-fit ​​or fastening. This connection process is cumbersome, typically requiring the opening of the snap-fit ​​or fastening mechanism to allow the sub-bed to detach or insert, which hinders the smoothness of the medical staff's operation. To address this issue, the locking mechanism of the snap-fit ​​or fastening mechanism has been removed. However, without a locking mechanism, the connection between the sub-bed and parent-bed structures becomes less secure, increasing the risk of accidental detachment. Therefore, the connection structure needs to be improved to resolve these technical problems. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a docking and interlocking structure for a bed frame of a bunk bed, which has the characteristics of high structural strength, good locking effect, reduced safety hazards of accidental disengagement, and convenient quick disengagement and insertion of the bunk bed.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A docking and interlocking structure for a bunk bed frame is provided, including a mother bed structure and a daughter bed structure. A notch is provided on one side of the lower part of the mother bed structure. A socket is provided at the lower part of the daughter bed structure, and the socket can be inserted into the notch. At least two self-locking structures are arranged side-by-side on the sidewalls where the notch and socket meet. Each self-locking structure includes a docking shaft, a hook arm, and a hooking roller. The docking shaft is rotatably mounted on the notch. One end of the docking shaft and the hook arm are fixedly docked. A hooking roller is rotatably mounted on the other end of the hook arm. A hook foot structure that docks with the hooking roller is installed on the socket. A torsion spring structure is installed between the docking shaft and the hook arm. The end of the hook arm where the hooking roller is mounted is always tilted downwards under the action of the torsion spring structure.

[0005] In this technical solution, an upper insertion notch is provided on the mother bed structure to facilitate the matching and insertion of the daughter bed structure. An insertion seat is provided on the daughter bed structure to facilitate docking with the insertion seat. A self-locking structure is provided to facilitate quick fixing and docking of the mother bed structure and the daughter bed structure. A hook arm is provided as a docking support for docking with the hook foot structure. A docking shaft is installed to facilitate the rotation of the hook arm. A torsion spring structure is installed so that the end of the hook arm that mounts the hooking roller can always tilt downwards to act as a docking part for hooking the daughter bed structure. A hooking roller is also provided to facilitate docking with the hook foot structure.

[0006] As a supplement to this technical solution, the self-locking structure also includes a hook arm cover, which is fixedly installed in the insertion notch, and the two ends of the docking shaft are rotatably installed in the hook arm cover. In this technical solution, the hook arm cover is used to protect the hook arm.

[0007] As a supplement to this technical solution, several guide rollers are installed side by side on the left and right side walls of the insertion notch. The guide rollers are used to facilitate the stable movement of the insertion socket.

[0008] As a supplement to this technical solution, longitudinal guide frames are installed on both sides of the plug-in socket to facilitate the stable operation of the guide rollers.

[0009] As a supplement to this technical solution, a buffer pad is provided on the lower side of the self-locking structure. The buffer pad corresponds to the hook foot structure. The buffer pad is used to absorb the impact force when the sub-bed structure is inserted, thereby improving the durability of the equipment and reducing the noise when the sub-bed structure is inserted.

[0010] As a supplement to this technical solution, the hook foot structure is provided with an upwardly protruding hook foot protrusion on the upper side of the end near the mother bed structure, and a guide slope is provided on the end of the hook foot protrusion near the mother bed structure, and an arc-shaped hook groove is provided on the other end of the hook foot protrusion.

[0011] In this technical solution, the hook foot protrusion of the hook foot structure is used to facilitate the insertion and removal of the sub-bed structure. When the sub-bed structure is inserted, the hook foot protrusion will contact the hooking roller on the hook arm. Through the guide slope on the hook foot protrusion, the hook foot structure pushes the hooking roller. The hooking roller is pushed, and the hook arm will lift around the connecting shaft. When the hooking roller leaves the guide slope and is engaged in the arc-shaped hook groove, the hook arm is pressured by the torsion spring structure and will be engaged in the arc-shaped hook groove. The hooking roller abuts against the hook foot structure, so that the mother bed structure and the sub-bed structure are connected.

[0012] When the sub-bed structure needs to be pulled out, if the tension on the sub-bed structure is greater than the clamping force of the torsion spring structure, the hook roller rolls along the arc-shaped hook groove, allowing the hook roller to disengage from the arc-shaped hook groove. Then the hook roller can enter the guide slope, at which point the sub-bed structure can be pulled out smoothly.

[0013] Beneficial Effects: This utility model relates to a docking and interlocking structure for a bunk bed frame. It features an upper insertion notch on the mother bed structure for easy insertion and matching of the child bed structure, an insertion seat on the child bed structure for easy docking, a self-locking structure for quick and secure docking of the mother and child bed structures, a hook arm as a docking support for docking with the hook foot structure, a docking shaft for rotation of the hook arm, and a torsion spring structure ensuring that the end of the hook arm with the hooking roller always tilts downwards to hook the child bed structure. The hook roller also facilitates docking with the hook foot structure. This design features high structural strength, good locking effect, reduced safety hazards from accidental disengagement, and easy and quick disengagement and insertion of the child bed.

[0023] The embodiments of this utility model relate to a docking and interlocking structure for a bunk bed frame, such as... Figure 1 As shown in Figure 5, the structure includes a mother bed structure 1 and a daughter bed structure 5. The lower part of the mother bed structure 1 is provided with a plug-in notch 2. The lower part of the daughter bed structure 5 is provided with a plug-in seat 6, which can be inserted into the plug-in notch 2. At least two self-locking structures 3 are arranged side by side on the side wall where the plug-in notch 2 and the plug-in seat 6 are connected. The self-locking structure 3 includes a docking shaft 11, a hook arm 10, and a hooking roller 12. The docking shaft 11 is rotatably mounted on the plug-in notch 2. The docking shaft 11 and one end of the hook arm 10 are fixedly connected. The hooking roller 12 is rotatably mounted on the other end of the hook arm 10. The plug-in seat 6 is equipped with a hook foot structure 7 that connects with the hooking roller 12. A torsion spring structure is installed between the docking shaft 11 and the hook arm 10. The end of the hook arm 10 where the hooking roller 12 is mounted is always tilted downward under the action of the torsion spring structure.

[0024] In this technical solution, an upper insertion notch 2 is provided on the mother bed structure 1 to facilitate the matching and insertion of the daughter bed structure 5. An insertion seat 6 is provided on the daughter bed structure 5 to facilitate docking with the insertion seat 6. At the same time, a self-locking structure 3 is provided to facilitate the quick fixing and docking of the mother bed structure 1 and the daughter bed structure 5. A hook arm 10 is provided to serve as a docking bracket for docking with the hook foot structure 7. A docking pivot 11 is installed to facilitate the rotation of the hook arm 10. At the same time, a torsion spring structure is installed so that the end of the hook arm 10 that is equipped with the hooking roller 12 can always be tilted downwards to serve as a docking part for hooking the daughter bed structure 5. The hooking roller 12 is also provided to facilitate docking with the hook foot structure 7.

[0025] like Figure 6 As shown, as a supplement to this technical solution, the self-locking structure 3 also includes a hook arm cover 8, which is fixedly installed in the insertion notch 2. The two ends of the docking shaft 11 are rotatably installed in the hook arm cover 8. In this technical solution, the hook arm cover 8 is used to protect the hook arm 10.

[0026] As a supplement to this technical solution, several guide rollers 4 are installed side by side on the left and right side walls of the insertion notch 2. The guide rollers 4 are used to facilitate the stable movement of the insertion seat 6.

[0027] like Figure 7 As shown, as a supplement to this technical solution, longitudinal guide frames 13 are installed on both sides of the plug-in 6. The longitudinal guide frames 13 are used to facilitate the stable operation of the guide rollers 4.

[0028] As a supplement to this technical solution, the self-locking structure 3 is provided with a buffer pad 9 on its lower side. The buffer pad 9 corresponds to the hook foot structure 7. The buffer pad 9 is used to absorb the impact force when the sub-bed structure 5 is inserted, thereby improving the durability of the equipment and reducing the noise when the sub-bed structure 5 is inserted.

[0029] As a supplement to this technical solution, the hook foot structure 7 is provided with an upwardly protruding hook foot protrusion 16 on the upper side of one end near the mother bed structure 1, and a guide slope 14 is provided on the other end of the hook foot protrusion 16 near the mother bed structure 1. An arc-shaped hook groove 15 is provided on the other end of the hook foot protrusion 16.

[0030] In this technical solution, the hook protrusion 16 of the hook foot structure 7 is used to facilitate the insertion and removal of the sub-bed structure 5. When the sub-bed structure 5 is inserted, the hook protrusion 16 will contact the hooking roller 12 on the hook arm 10. Through the guide slope 14 on the hook protrusion 16, the hook foot structure 7 pushes the hooking roller 12. The hooking roller 12 is pushed, and the hook arm 10 will be lifted around the connecting shaft 11. When the hooking roller 12 leaves the guide slope 14 and is inserted into the arc-shaped hook groove 15, the hook arm 10 is pressured by the torsion spring structure and will be inserted into the arc-shaped hook groove 15. The hooking roller 12 abuts against the hook foot structure 7, so that the mother bed structure 1 and the sub-bed structure 5 are connected.

[0031] When the sub-bed structure 5 needs to be pulled out, the tension on the sub-bed structure 5 is greater than the clamping force of the torsion spring structure. The hook roller 12 rolls along the arc-shaped hook groove 15, so that the hook roller 12 can disengage from the arc-shaped hook groove 15. Then the hook roller 12 can enter the guide slope 14, at which point the sub-bed structure 5 can be pulled out smoothly.

[0032] Example

[0033] When the sub-bed structure 5 needs to be inserted into the mother bed structure 1, firstly, the insertion seat 6 of the sub-bed structure 5 enters the insertion notch 2. The longitudinal guide frame 13 on both sides of the insertion seat 6 contacts the guide roller 4, so that the insertion seat 6 enters the insertion notch 2 stably. Then, the hook foot structure 7 contacts the hook roller 12. The guide slope 14 on the hook foot structure 7 pushes the hook roller 12, so that the end of the hook arm 10 where the hook roller 12 is installed is raised upward until the hook roller 12 is disengaged from the guide slope 14 and is inserted into the arc-shaped hook groove 15, so that the hook roller 12 can be inserted into the hook foot structure 7. After completion, the mother bed structure 1 and the sub-bed structure 5 are connected.

[0034] When the hook structure 7 is engaged, it will come into contact with the buffer pad 9. The buffer pad 9 can absorb the impact force and reduce the noise during the docking operation.
