Description

Technical Field

[0001] This utility model relates to the technical field of beds, and more specifically, to a folding bed frame. Background Technology

[0002] A folding bed is a temporary bed frame that is usually folded up after use, making it practical and space-saving. For example, Chinese patent CN216628023U discloses a folding bed where the U-shaped rotating legs are rotatably mounted at both ends of the bed frame via a connecting assembly, allowing the U-shaped rotating legs to be folded. A slider is movably fitted onto the side beams of the bed frame, and one end of a connecting rod is fixed to the slider, while the other end is fixed to the U-shaped rotating legs. The rotation of the rotating legs at both ends of the bed frame can be controlled by manipulating the distance and direction of the slider on the side beams.

[0003] Therefore, it can be seen that in the existing bed frame structure, the slider does not have a locking mechanism. If the slider is too tight, it is difficult for the user to slide it open. However, if the slider is too loose, the user is likely to misoperate the slider during use, causing the U-shaped rotating legs to swing and thus causing the bed frame to collapse. Utility Model Content

[0004] In order to overcome the defects of the existing technology, the present invention provides a folding bed frame to solve the problems in the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a folding bed frame, including a frame, with curved seats hinged to each other on the corresponding sides of the two ends of the frame through hinge shafts, the curved seats being clamped on the frame, the curved seats on both sides being connected by support legs, and a retractable positioning pin assembly installed on one side of the curved seat, the positioning pin assembly locking or unlocking the curved seat from the frame.

[0006] In the aforementioned folding bed frame, the positioning pin assembly includes a pin cylinder, a movable pin rod is installed inside the pin cylinder, one end of the pin rod is provided with a handle, and the other end is provided with a plug rod that can extend out of the pin cylinder. The curved seat and the frame are provided with corresponding insertion holes. The end of the pin cylinder near the plug rod is fixedly installed on the side of the curved seat, and the plug rod corresponds to the insertion hole.

[0007] In the aforementioned folding bed frame, a first slot and a second slot are respectively provided on the circumference of the pin cylinder near the handle end, and a protruding locking rod is provided on the pin rod. The locking rod switches positions between the first slot and the second slot, so that the pin rod extends out or retracts from the pin cylinder.

[0008] In the aforementioned folding bed frame, a spring cavity is provided inside the pin cylinder, a spring limiting ring is provided between the pin rod and the insert rod, a pin spring is provided inside the spring cavity, and the pin rod passes through the pin spring, such that one end of the pin spring abuts against the upper inner end of the spring cavity, and the other end abuts against the spring limiting ring.

[0009] In the aforementioned folding bed frame, a long spring is connected to one end of the support leg away from the positioning pin assembly. One end of the long spring is fixedly connected to the support leg, and the other end is fixedly connected to the frame.

[0010] In the aforementioned folding bed frame, a roller assembly is installed on the support legs. When the support legs are folded, the roller assembly drives the frame to move.

[0011] In the aforementioned folding bed frame, the support legs are U-shaped, the roller assembly includes a reinforcing rod, the two ends of which are respectively connected to the two ends of the support legs, and at least two pulleys are installed on the reinforcing rod.

[0012] The beneficial effects of this utility model are as follows: by installing a positioning pin assembly on the crank seat, after the support legs at both ends of the frame are opened, the positioning pin assembly can lock the crank seat on the frame by telescopic movement, preventing the support legs from folding up.

Detailed Implementation

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Combination Figures 1 to 7 The folding bed frame shown includes a frame 1. Hinged seats 2 are hinged to corresponding sides at both ends of the frame 1 via hinge shafts 6. The hinge seats 2 are held in place by the frame 1. Corresponding hinge seats 2 on both sides are connected by support legs 3. A retractable positioning pin assembly 5 is installed on one side of the hinge seat 2, which locks or unlocks the hinge seat 2 to the frame 1. A roller assembly is installed on the support legs 3. When the support legs 3 are folded, the roller assembly drives the frame 1 to move. In this embodiment, by installing the positioning pin assembly 5 on the hinge seats 2, after the support legs 3 at both ends of the frame 1 are opened, the positioning pin assembly 5 can retract and move to lock the hinge seats 2 to the frame 1, preventing the support legs 3 from folding up. The operation is simpler and more convenient than existing technologies. Furthermore, when folded up, the frame 1 can be moved by the roller assembly on the support legs 3, making it easy to move the frame 1 and place it under a bed in the home.

[0023] It is worth noting that the frame 1, curved seat 2 and support leg 3 in this embodiment are made of metal, such as aluminum alloy. Multiple support ribs are welded on the surface of the frame 1 to support the bed board or bed.

[0024] like Figures 3 to 7 As shown, the positioning pin assembly 5 in this embodiment includes a pin cylinder 9, in which a movable pin rod 13 is installed. One end of the pin rod 13 is provided with a handle 14, and the other end is provided with a rod 17 that can extend out of the pin cylinder 9. Corresponding insertion holes are provided on the crank seat 2 and the frame 1. The end of the pin cylinder 9 near the rod 17 is fixedly installed on the side of the crank seat 2, and the rod 17 corresponds to the insertion hole. After the support legs 3 at both ends are fully opened, the insertion holes on the crank seat 2 and the frame 1 are aligned. Then, the pin rod 13 is moved so that the rod 17 is inserted into the insertion hole on the crank seat 2 and the frame 1, thereby locking the crank seat 2 on the frame 1 and preventing the support legs 3 from folding. The operation is simple and convenient.

[0025] Specifically, a first slot 10 and a second slot 11 are respectively opened on the circumference of the pin cylinder 9 near the handle 14. The depth of the first slot 10 is greater than the depth of the second slot 11. A protruding locking rod 16 is provided on the pin rod 13. The locking rod 16 switches positions between the first slot 10 and the second slot 11, so that the pin rod 17 extends out or retracts from the pin cylinder 9. By moving the pin rod 13, the locking rod 16 is engaged in the first slot 10 or the second slot 11, so that the operator can know whether the pin rod 17 is inserted into or disengaged from the socket.

[0026] The pin cylinder 9 has a spring cavity 12, and a spring limiting ring 15 is provided between the pin rod 13 and the rod 17. The spring cavity 12 has a pin spring 18, and the pin rod 13 passes through the pin spring 18, so that one end of the pin spring 18 abuts against the upper inner end of the spring cavity 12, and the other end abuts against the spring limiting ring 15. When the operator moves the pin rod 13, the pin spring 18 is compressed, and the locking rod 16 corresponds to the first locking groove 10 or the second locking groove 11. After releasing the operator, the pin spring 18 can be reset, and the locking rod 16 can be locked into the first locking groove 10 or the second locking groove 11 to prevent the pin rod 13 from moving inside the pin cylinder 9.

[0027] In this embodiment, the end of the support leg 3 away from the positioning pin assembly 5 is connected to a long spring 4. One end of the long spring 4 is fixedly connected to the support leg 3, and the other end is fixedly connected to the frame 1. This allows the long spring 4 to be stretched when the support leg 3 is folded. Under the pressure of the frame 1, the support leg 3 will not open and support the frame 1. When needed, the operator only needs to lift one end of the frame 1, and the support leg 3 will open under the return pull of the long spring 4, making the operation more convenient.

[0028] In this embodiment, the support leg 3 is U-shaped. The roller assembly includes a reinforcing rod 7, with both ends of the reinforcing rod 7 connected to the two ends of the support leg 3. At least two pulleys 8 are installed on the reinforcing rod 7. The reinforcing rod 7 can make the structure of the U-shaped support leg 3 more stable. Moreover, after the support leg 3 is folded, the support leg 3 is placed flat under the frame 1, so that the pulleys 8 are supported on the ground, thereby facilitating the movement of the frame 1.

[0029] When the support leg 3 is folded, the pulley 8 is in a vertical position to facilitate ground support. In some other embodiments, the pulley 8 can be a caster wheel, so that the frame 1 can move in multiple directions after the support leg 3 is folded.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
