Description

Technical Field

[0001] This utility model belongs to the field of support technology, and in particular relates to a sliding opening and closing locking structure for a massage bed. Background Technology

[0002] Existing massage bed leg support structures generally suffer from limited adjustment functionality and insufficient stability. Traditional designs often employ fixed structures or simple single-point locking mechanisms, failing to simultaneously meet the different needs of both storage and use. In existing technologies, single-point locking structures are prone to loosening and wobbling during position changes, while complex multi-level adjustment mechanisms suffer from inconvenient operation and a tendency to jam. Especially in commercial environments, frequent adjustments significantly compromise the durability and ease of operation of existing structures, necessitating a solution that provides multiple stable locking positions and is easy to operate. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a sliding opening and closing locking structure for a massage bed.

[0004] To achieve the above objectives, the technical solution adopted is: A sliding opening and closing locking structure for a massage bed includes a main bed body. One end of the main bed body is connected to a leg support. The leg support can move relative to the main bed body in a direction away from or close to the main bed body to achieve opening and closing. The main bed body and the leg support are connected by a swing rod. The lower end of the swing rod is rotatably connected to the main bed body, and the upper end of the swing rod is rotatably connected to a sliding frame. The sliding frame is slidably connected to the leg support. The leg support is provided with a first locking mechanism for limiting the sliding frame, and a second locking mechanism is provided between the swing rod and the sliding frame, so that the swing rod is in a locked or unlocked state.

[0005] The beneficial effects of adopting the above technical solution are as follows: the horizontal movement of the leg support adapts to different user body shapes, expanding the scope of use; the main bed and the leg support are hinged by a swing arm, and the swing arm mechanism converts the horizontal movement into an arc trajectory including three states: open, upright, and closed, avoiding the jamming problem of linear guide rails; the sliding connection between the sliding frame and the leg support allows the leg support to remain stable during movement, reducing friction and jamming, and improving the smoothness of adjustment; the locking mechanism controls the rotation angle of the swing arm and the position of the sliding frame, so that the leg support is in different locking states relative to the main bed, improving stability and preventing the leg support from sliding relative to the main bed.

[0006] Preferably, the first locking mechanism includes a claw assembly, and the leg support is provided with a crossbar, the claw assembly being connected to the lower end of the crossbar.

[0007] The advantages of adopting the above-mentioned preferred technical solution are as follows: the claw assembly, as the core component of the first locking mechanism, realizes the rapid locking and release of the sliding frame through mechanical engagement, and the cross frame provides a stable installation foundation.

[0008] Preferably, the claw assembly is configured as two sets, located at the end closer to the main bed and the end farther from the main bed, respectively.

[0009] The beneficial effect of adopting the above-mentioned preferred technical solution is that the two sets of claw assemblies are used to limit the sliding frame of the leg bracket in two locking states.

[0010] Preferably, the claw assembly includes a claw, which is rotatably connected to the crossbeam via a rotating shaft, and a torsion spring is sleeved on the rotating shaft or a first spring is connected to one end of the claw.

[0011] Preferably, a connecting block is provided below the claw, the two lever arms of the torsion spring are connected to the claw and the connecting block respectively, and the two ends of the first spring are connected to the claw and the connecting block respectively.

[0012] The beneficial effect of adopting the above-mentioned preferred technical solution is that the torsion spring or the first spring provides an automatic reset force, so that the pawl can quickly return to the unlocked state after the external force is released.

[0013] Preferably, the first locking mechanism includes a first limiting block located at the lower end of the leg support. Two first limiting blocks are provided, located near the main bed body and away from the main bed body, respectively.

[0014] The beneficial effect of adopting the above-mentioned preferred technical solution is that the two sets of claw assemblies are used to limit the sliding frame of the leg bracket in two locking states.

[0015] Preferably, the second locking mechanism includes a second limiting block and a first limiting shaft. The second limiting block is located at the lower end of the sliding frame, and the first limiting shaft is disposed on the second limiting block. The first limiting block limits the sliding frame by limiting the first limiting shaft.

[0016] The beneficial effect of adopting the above-mentioned preferred technical solution is that the cooperation between the first limiting block and the first limiting shaft realizes the locking state of the leg support and the sliding frame.

[0017] Preferably, the swing arm is provided with a through hole, and a second limiting shaft is provided in the through hole. The lower end of the second limiting block is provided with a protrusion. The protrusion contacts or separates from the second limiting shaft to realize the locking or unlocking state of the sliding frame and the swing arm.

[0018] Preferably, the second locking mechanism is configured as two sets, and the first limiting shafts of the two sets of second locking mechanisms correspond to the two first limiting blocks near the main bed body end and away from the main bed body end, respectively. More preferably, the two first limiting shafts are located between the two first limiting blocks.

[0019] The beneficial effect of adopting the above-mentioned preferred technical solution is that the cooperation between the two sets of first limiting blocks and the first limiting shaft makes the leg support in different locking states relative to the main bed.

[0020] More preferably, the inner side of the leg support is provided with a slide rail, and the two ends of the sliding frame are provided with rollers. The rollers roll along the slide rail to realize the sliding connection between the sliding frame and the leg support.

[0021] The beneficial effects of adopting the above-mentioned preferred technical solution are that the cooperative design of the slide rail and roller further reduces sliding friction, making the movement of the leg support easier and smoother.

[0022] Preferably, the second limiting block is connected to the sliding frame by bolts. The second limiting block is provided with a sliding groove. The second limiting block moves relative to the sliding frame and bolts within the range of the sliding groove. The first limiting shaft is located at the end of the second limiting block away from the main bed. The inner cavity of the other end of the second limiting block is provided with a second spring and a third limiting block connected to each other. The third limiting block is located at the end of the second spring near the first limiting shaft. That is, the two ends of the second spring are respectively connected to the second limiting block and the third limiting block. The upper end of the third limiting block is connected to the sliding frame.

[0023] The beneficial effects of adopting the above-mentioned preferred technical solution are as follows: When the second locking mechanism is in the locked state, the swing arm is in the upright state. Continue to pull the leg support until the first limiting block close to the main bed body contacts the first limiting shaft. Continue to pull the leg support so that the first limiting block knocks open the first limiting shaft, thereby unlocking. The first limiting shaft drives the second limiting block to move away from the main bed body relative to the sliding frame and bolt. The two ends of the second spring are squeezed by the second limiting block and the third limiting block. After unlocking, the second limiting block returns to its original position under the elastic restoring force of the spring.

[0024] Compared with existing technologies, the advantages of this invention are as follows: This invention features a sliding opening and closing mechanism with both upright and stably locked extended states, catering to both storage and usage needs. Through the swing arm linkage mechanism and dual locking system, users can easily and reliably switch between the fully retracted and fully extended leg supports. Two independently operating claw assemblies correspond to different usage states, significantly improving the practicality and user experience of the massage bed, making it particularly suitable for commercial applications requiring frequent adjustments.

The leg support 2 can move relative to the main bed body 1 in a direction away from or close to the main bed body 1 to achieve opening and closing. The main bed body 1 and the leg support 2 are connected by a swing rod 6. The lower end of the swing rod 6 is rotatably connected to the main bed body 1, and the upper end of the swing rod 6 is rotatably connected to a sliding frame 12. The sliding frame 12 is slidably connected to the leg support 2. The leg support 2 is provided with a first locking mechanism for limiting the sliding frame 12, and a second locking mechanism is provided between the swing rod 6 and the sliding frame 12, so that the swing rod 6 is in a locked or unlocked state.

[0035] In an optional embodiment, the first locking mechanism includes a first limiting block 9 located at the lower end of the leg support 2. Two first limiting blocks 9 are provided, located at the end closer to the main bed body 1 and the end farther away from the main bed body 1, respectively.

[0036] In an optional embodiment, the second locking mechanism includes a second limiting block 15 and a first limiting shaft 8. The second limiting block 15 is located at the lower end of the sliding frame 12, and the first limiting shaft 8 is disposed on the second limiting block 15. The first limiting block 9 limits the sliding frame 12 by limiting the first limiting shaft 8.

[0037] In an optional embodiment, the swing arm 6 is provided with a through hole, and a second limiting shaft 14 is provided in the through hole. The lower end of the second limiting block 15 is provided with a protrusion 10. The protrusion 10 contacts or separates from the second limiting shaft 14 to realize the locking or unlocking state of the sliding frame 12 and the swing arm 6.

[0038] In this embodiment, the second locking mechanism is configured as two sets, and the first limiting shafts 8 of the two sets of second locking mechanisms correspond to the two first limiting blocks 9 that are close to the end of the main bed body 1 and far from the end of the main bed body 1, respectively. More preferably, the two first limiting shafts 8 are located between the two first limiting blocks 9.

[0039] In an optional embodiment, the inner side of the leg support 2 is provided with a slide rail 13, and the two ends of the sliding frame 12 are provided with rollers. The rollers roll along the slide rail 13 to realize the sliding connection between the sliding frame 12 and the leg support 2.

[0040] In this embodiment, the second limiting block 15 is connected to the sliding frame 12 by bolts 19. The second limiting block 15 is provided with a sliding groove 20. The second limiting block 15 moves relative to the sliding frame 12 and bolts 19 within the range of the sliding groove 20. The first limiting shaft 8 is located at one end of the second limiting block 15 away from the main bed body 1. The other end of the second limiting block 15 is provided with a second spring 21 and a third limiting block 22 connected to each other. The third limiting block 22 is located at one end of the second spring 21 near the first limiting shaft 8. That is, the two ends of the second spring 21 are respectively connected to the second limiting block 15 and the third limiting block 22. The upper end of the third limiting block 22 is connected to the sliding frame 12.

[0041] In the initial state, the leg support 2 is fully retracted towards the main bed 1, the swing arm 6 remains tilted forward towards the main bed 1 and rests against the main bed 1, the sliding frame 12 contacts the slide rail 13 via rollers, and the claw 17 (rear claw) at the end away from the main bed 1 locks the sliding frame 12; pulling the leg support 2 outwards in the direction away from the main bed 1 causes the swing arm 6 to rotate until the protrusion 10 on the second limiting block 15 on the swing arm 6 is abutted by the lower second limiting shaft 14, and the swing arm 6 rotates to an upright position to prevent the swing arm 6 from tilting forward. At the same time, the end away from the main bed 1... The first limiting block 9 limits the first limiting shaft 8 at the end away from the main bed 1, achieving the first locking state. When sufficient external force is applied to pull the leg support 2, the pawl 17 overcomes the force of the first spring 5 or the torsion spring 4 and rotates around the rotating shaft 16 to release the sliding frame 12, thus unlocking it. Continuing to pull the leg support 2 causes it to move away from the main bed 1 relative to the sliding frame 12. The swing arm 6 remains upright. Continuing to pull the leg support 2 until the first limiting block 9 near the main bed 1 contacts the first limiting shaft 8, and continuing to pull the leg support 2 causes the first limiting state to be reached. Block 9 breaks open the first limiting shaft 8, unlocking the device. The first limiting shaft 8 drives the second limiting block 15 to move away from the main bed 1 relative to the sliding frame 12 and bolt 19. The two ends of the second spring 21 are squeezed by the second limiting block 15 and the third limiting block 22. After unlocking, the elastic restoring force of the spring causes the second limiting block 15 to return to its original position. After unlocking, the second limiting block 15 breaks free from the second limiting shaft 14, and the swing arm 6 can start to rotate from the upright position away from the main bed 1, driving the sliding frame 12 and the swing arm 6 to move. The swing arm 6 tilts backward after rotation, and the sliding frame... 12 slides within the slide rail 13 of the leg support 2 until the leg support 2 is fully opened. The first limiting block 9 near the end of the main bed 1 limits the first limiting shaft 8 near the end of the main bed 1, and the pawl 17 near the end of the main bed 1 contacts the sliding frame 12. The external force continues to drag the leg support 2, and the pawl 17 continues to move towards the sliding frame 12. Under the action of the first spring 5 or torsion spring 4, the pawl 17 rotates around the rotating shaft 16, so that the sliding frame 12 is locked under the pawl 17 (front pawl) near the end of the main bed 1, which is the second locking state.

[0042] The retracted and extended states operate on the same principle. Forcefully push the leg support 2 towards the main bed 1 until the swing arm 6 is pulled to an upright position. The protrusion 10 on the second limiting block 15 of the swing arm 6 is abutted by the second limiting shaft 14 below. During this period, the first limiting block 9 near the main bed 1 remains in a limiting position against the first limiting shaft 8 near the main bed 1, and the sliding frame 12 remains locked by the pawl 17, reaching the third locking state. Continue pushing the leg support 2; the pawl 17 near the main bed 1 disengages from the sliding frame 12, and the second limiting block 15 on the swing arm 6 disengages from the second limiting shaft 14, unlocking the leg support 2. Continue pushing the leg support 2 back to its initial state. In the locked state, it can stably support the user.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
