Description

Technical Field

[0001] This utility model relates to the field of folding bed technology, and specifically to a folding bed support component. Background Technology

[0002] Portable folding beds are popular among outdoor enthusiasts and office workers due to their ease of storage, convenient use, and small footprint during transport. Portable folding beds typically consist of a detachable bed frame and a bed surface. Assembly involves first assembling the folding bed, then attaching the bed frame to the supporting structure.

[0003] In the prior art, such as the Chinese utility model patent with authorization announcement number CN215190490U, an adjustable support structure for a leisure bed and the leisure bed itself are disclosed. The support structure mainly consists of a support crossbar, a support base, a connecting rod, an adjusting bracket, and legs. During installation, the supporting structure of this prior art involves first fitting one end of the connecting rod onto the connecting base, then placing the assembled components into the mounting groove of the adjusting bracket, and movably connecting the adjusting bracket and the connecting base. Next, the other end of the connecting rod is connected to the second connecting hole of the support base. Finally, a locking device is connected to the adjusting bracket and the connecting rod, thus completing the installation of the support structure.

[0004] In the aforementioned prior art, when installing the support structure and the bed frame, it is necessary to first assemble the crossbar, support, connecting rod, adjusting bracket and legs. When storing, it is also necessary to disassemble them for easy storage. Whether it is assembling or disassembling and storing the support structure, the operation process is relatively cumbersome and inconvenient to use. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a folding bed support component to solve the issues that the assembly, disassembly, and storage processes of existing support structures are cumbersome and inconvenient to use.

[0006] This utility model is achieved using the following technical solution: a folding bed support component, including a crossbeam, with a first arm and a second arm hinged to both ends of the crossbeam. Both the first arm and the second arm have an upward first state and a second state retracted to the bottom side of the crossbeam. The direction in which the first arm and the second arm move from the second state to the first state is the first direction, and the direction in which they move from the first state to the second state is the second direction. Both ends of the crossbeam are provided with a first limiting part to prevent the first arm and the second arm from continuing to rotate in the first direction in the first state. The end of the first arm away from the crossbeam is provided with a first supporting claw, and the end of the second arm away from the crossbeam is hinged with a rotating arm. The end of the rotating arm away from the crossbeam is fixedly connected with a second supporting claw. A locking mechanism is provided between the rotating arm and the second arm to lock the position of the rotating arm. When the first arm and the second arm are in the first state and the locking mechanism is in the locked state, the opening directions of the first supporting claw and the second supporting claw are opposite.

[0007] With the above structure, when the device is not in use, the first and second arms are retracted to the bottom of the crossbeam. When the support is needed, simply rotate the first and second arms to extend them upwards to the first extended state. Then, the bed frame is secured to the first and second support claws. The bed frame exerts an inward force on the first and second arms, and under the action of the first limiting part, the first and second arms can be stably maintained in the first state, thus supporting the bed frame. When not in use, simply separate the support from the bed frame and rotate the first and second arms to return them to the second state for storage. Therefore, this support is more convenient to assemble, disassemble, and store.

[0008] Preferably, the second arm is provided with a first mounting groove for accommodating the rotating arm, and a limiting groove is provided on the inner wall of the first mounting groove away from the second support claw; the locking mechanism includes a second sliding groove provided at the end of the rotating arm away from the second support claw, and a locking tongue is slidably installed in the second sliding groove, the end of the locking tongue away from the second support claw being able to be inserted into the limiting groove. Through the cooperation of the locking tongue and the limiting groove, when the second arm rotates into the first mounting groove, the locking tongue can be inserted into the limiting groove, thereby preventing the second arm from disengaging from the first mounting groove. The structure is simple and the operation is convenient.

[0009] Preferably, the rotating arm has a first slide groove communicating with the second slide groove on the side away from the second arm, and a push block is slidably installed on the first slide groove, the push block being fixedly connected to the locking tongue. The push block makes it easier for the operator to move the locking tongue.

[0010] Preferably, a spring is provided between the end of the locking tongue near the second support claw and the inner wall of the second sliding groove. The spring allows the locking tongue to engage with the limiting groove under the action of the spring when the rotating arm is located in the first mounting groove, making operation more convenient.

[0011] Preferably, the latch includes a second limiting part that can extend out of the second slide groove and insert into the limiting groove, and a third connecting part that is fixedly connected to the push block. The end of the third connecting part away from the second support claw is fixedly connected to the second limiting part, and the second limiting part is wedge-shaped. By setting the wedge-shaped second limiting part, the latch can automatically retract into the second slide groove when the rotating arm moves into the first mounting groove, thus eliminating the need for additional operation and further improving the ease of operation of this device.

[0012] Preferably, the first limiting portion includes a first limiting surface and a second limiting surface. The bottom of the first limiting portion extends downward to form a hinge portion. Both the first and second support arms include a second connecting portion near the hinge portion. The hinge portion is inserted into the inner side of the second connecting portion and hinged to it. The inner side of the second connecting portion is also provided with a first mating surface and a second mating surface. When the first support claw and the second support claw are in the first state, the first mating surface is in contact with the first limiting surface, and the second mating surface is in contact with the second limiting surface. By having the first limiting surface in contact with the first mating surface and the second limiting surface in contact with the second mating surface, the first and second support arms can be prevented from continuing to move in the first direction under the action of the bed frame when in the first state, thus increasing the stability of the device.

[0013] Preferably, both the first and second support claws are provided with clearance grooves in the middle. The clearance grooves can avoid protruding hinge points on the bed frame.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] 1. By hinged the first and second arms to the crossbeam, when this support is needed, simply rotate the first and second arms to change it from the second state to the first state; conversely, when this support is not needed, simply rotate the first and second arms in the opposite direction to change it from the first state to the second state. This eliminates the need for assembly and disassembly of existing support structures, making operation more convenient.

[0016] 2. By setting the rotating arm, the position of the second support claw can be adjusted. When assembling with the bed frame, one side of the bed frame can be placed on the first support claw, and then the second support claw can be adjusted inward. Then the other side of the bed frame can be placed on the second support claw, and the rotating arm can be pressed into the first mounting groove to realize the assembly of the support and the bed frame, which further improves the ease of operation of this device.

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0027] like Figure 1 , Figure 2As shown, this utility model provides a folding bed support component, including a crossbeam 1. A first arm 2 and a second arm 5 are hinged to the left and right ends of the crossbeam 1, respectively. Both the first arm 2 and the second arm 5 have a first upward position and a second position retracted to the bottom of the crossbeam 1. The direction in which the first arm 2 moves from the second position to the first position is the first direction, and the direction in which it moves from the first position to the second position is the second direction. Both ends of the crossbeam 1 are provided with a first limiting part 17 to prevent the first arm 2 and the second arm 5 from continuing to rotate in the first direction in the first position. A first support claw 3 is fixedly connected to the end of the first arm 2 away from the crossbeam 1. A rotating arm 6 is hinged to the end of the second arm 5 away from the crossbeam 1. A second support claw 8 is fixedly connected to the end of the rotating arm 6 away from the crossbeam 1. Specifically, the end of the second arm 5 away from the crossbeam 1 is hinged to the end of the rotating arm 6 near the second support claw 8. A locking mechanism for locking the position of the rotating arm 6 is provided between the rotating arm 6 and the second support arm 5. When the first support arm 2 and the second support arm 5 are in the first state and the locking mechanism is in the locked state, the opening directions of the first support claw 3 and the second support claw 8 are opposite.

[0028] It should be noted that the first direction and the second direction mentioned above are not fixed directions. For the first arm 2, the first direction is counterclockwise and the second direction is clockwise. For the second arm 5, the first direction is clockwise and the second direction is counterclockwise.

[0029] The first state of the first arm 2 and the second arm 5 is as follows: Figure 1 As shown, the first arm 2 and the second arm 5 are inclined upwards. When the first arm 2 and the second arm 5 are in the first state, the opening directions of the first support claw 3 and the second support claw 8 are opposite. Specifically, the first support claw 3 is located on the right side of the crossbeam 1 and its opening direction is downward to the right, while the second support claw 8 is located on the left side of the crossbeam 1 and its opening direction is downward to the left.

[0030] like Figures 4 to 6 As shown, the second support arm 5 is provided with a first mounting groove 22 for accommodating the rotating arm 6, and a limiting groove 23 is provided on the inner wall of the first mounting groove 22 away from the second support claw 8. The locking mechanism includes a second sliding groove 30 provided at the end of the rotating arm 6 away from the second support claw 8, and a locking tongue 26 is slidably installed in the second sliding groove 30. The end of the locking tongue 26 away from the second support claw 8 can be inserted into the limiting groove 23, and a spring 31 is provided between the end of the locking tongue 26 near the second support claw 8 and the inner wall of the second sliding groove 30.

[0031] The locking tongue 26 is composed of a second limiting part 24 and a third connecting part 25. The second limiting part 24 is wedge-shaped and can be inserted into the limiting groove 23. The third connecting part 25 is fixedly connected to the end of the second limiting part 24 near the second support claw 8.

[0032] When the rotating arm 6 is pressed into the first mounting groove 22, the locking tongue 26 retracts towards the inside of the rotating arm 6 under the action of the wedge-shaped second limiting part 24. When the locking tongue 26 reaches the position of the limiting groove 23, it is inserted into the limiting groove 23 under the action of the spring 31, thus preventing the rotating arm 6 from rotating clockwise and disengaging from the second support arm 5. When it is necessary to combine with the bed frame 4, the rotating arm 6 needs to be rotated clockwise, so that the second support claw 8 retracts inward, making it easier to combine with the bed frame 4. The prerequisite for rotating the rotating arm 6 clockwise is to unlock the locking tongue 26, that is, to move the locking tongue 26 towards the second support claw 8. In order to make it easier to move the locking tongue 26, a first sliding groove 29 communicating with the second sliding groove 30 is provided on the side of the rotating arm 6 away from the second support arm 5. A push block 7 is slidably installed on the first sliding groove 29, and the push block 7 is fixedly connected to the third connecting part 25 of the locking tongue 26.

[0033] The first limiting part 17 includes a first limiting surface 18 and a second limiting surface 19 located at the left and right ends of the crossbeam 1. The bottom of the first limiting part 17 extends downward to form a hinge part 16. The first support arm 2 and the second support arm 5 both include a second connecting part 13 near the hinge part 16. The hinge part 16 is inserted into the inner side of the second connecting part 13 and hinged to the second connecting part 13. The inner side of the second connecting part 13 is also provided with a first mating surface 20 and a second mating surface 21. When the first support claw 3 and the second support claw 8 are in the first state, the first mating surface 20 is in contact with the first limiting surface 18, and the second mating surface 21 is in contact with the second limiting surface 19.

[0034] By using the interlocking surfaces, the first limiting part 17 can ensure that the force between the first arm 2, the second arm 5, and the crossbeam 1 is more stable when preventing the first arm 2 and the second arm 5 from moving further in the first direction, thereby further improving the stability of the support member in this utility model. Furthermore, by moving the hinge part 16 downwards, the first arm 2 and the second arm 5 can be retracted to... Figure 3 The position shown is the second state. When in the second state, it is more convenient to store the device and saves more space.

[0035] As a further illustration of this example, since there will be a protrusion at the hinge of the folding bed frame 4, in order to avoid the position of the protrusion, the middle part of the first support claw 3 and the second support claw 8 are both provided with a relief groove 12.

[0036] The operating principle of this device is as follows: When assembling a folding bed, first rotate the first arm 2 and the second arm 5 to bring them to the first state. Then unfold the folding bed, place one side of the bed frame 4 at the first support claw 3, release the locking mechanism of the rotating arm 6, and rotate the rotating arm 6 to retract the second support claw 8 inward. Place the other side of the bed frame 4 at the second support claw 8, and then rotate the rotating arm 6 counterclockwise until it is placed in the first mounting slot 22 and the locking mechanism is engaged. At this point, the support member and the bed frame 4 are combined, and the folding bed can be supported by the second connecting part 13 and the hinge part 16. In actual use, multiple support members are often needed to firmly support the folding bed. When the folding bed needs to be stored, release the locking mechanism, rotate the rotating arm 6 clockwise, remove the folding bed for tidying, and then rotate the rotating arm 6 back to return the first arm 2 and the second arm 5 to the second state for easy storage.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
