Description

Technical Field

[0001] This utility model relates to the field of lumbar traction, and in particular to a lumbar traction device. Background Technology

[0002] A lumbar traction device is a rehabilitation instrument that uses controlled mechanical traction to stretch the intervertebral space, reduce intervertebral disc pressure and nerve compression, and is often used to relieve conditions such as lumbar disc herniation and lumbar muscle strain.

[0003] During lumbar traction, the user lies on the bed, and straps are used to secure the user's chest and hips. A controller then moves an internal electric telescopic rod along the bed surface, moving the hip straps to pull the user's lumbar spine. However, the maximum stretching distance cannot be quickly determined during this movement, resulting in excessive traction force and potentially causing injury to the user. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the moving plate is moving, the maximum stretching distance cannot be quickly determined, resulting in a large traction force and thus causing injury to the user.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a lumbar traction device, including a bed, a controller is provided on one side of the bed, a movable plate is provided at the upper end of the bed, a strap is provided on one side of both the bed and the movable plate, and a protective device is provided on both sides of the bed. The protective device limits the maximum displacement of the movable plate by using a locking block to limit the sliding block inside the first slide rail, thereby completing the protection of the user.

[0006] The effect achieved by the above components is as follows: when performing lumbar traction, the maximum displacement distance of the moving plate is adjusted through the protective device. Then, the user lies on the bed, and the straps are used to fix the user's chest and hips. Then, through the controller, the electric telescopic rod inside the bed moves the moving plate along the surface of the bed, and then moves the straps around the hips to perform lumbar traction on the user.

[0007] Preferably, the protective device includes a first slide rail, a locking block, and a sliding block. The first slide rail is disposed on the side of the bed body near the moving plate. A plurality of through holes are provided on one side of the first slide rail. The locking block is inserted into the through holes on the surface of the first slide rail to limit the sliding block. One side of the sliding block is fixed to the moving plate and moves inside the first slide rail.

[0008] The effect achieved by the above components is as follows: Before using the moving plate, the locking block is inserted into a suitable through hole on one side of the first slide rail on the bed surface, thus limiting the movement distance of the sliding block inside the slide rail. When the moving plate moves on the bed, it will drive the sliding block fixed on one side to move. The sliding block then slides inside the first slide rail, and after the sliding block moves to the locking block, it blocks the locking block, and the moving plate stops moving. Then, the user can use the controller to stop the electric telescopic rod inside the bed body and lock it, so that the moving plate is no longer moved and the position after movement is guaranteed. By using the protective device, the moving plate can only move to the preset maximum position. The electric telescopic rod inside the bed body can be closed by the controller, thus avoiding injury to the user and improving the effectiveness of the lumbar traction device.

[0009] Preferably, a buffer block is provided on the side of the sliding block near the locking block, and the buffer block is a rubber block to buffer the force applied to the sliding block and the locking block.

[0010] The effect achieved by the above components is that by fixing a buffer block, which is a rubber block, to one side of the sliding block, the damage to the locking block is reduced when the sliding block and the locking block come into contact.

[0011] Preferably, a reinforcing plate is provided between the sliding block and the moving plate, and the reinforcing plate improves the connection strength between the sliding block and the moving plate.

[0012] The effect achieved by the above components is to improve the connection strength between the sliding block and the moving plate by fixing the reinforcing plate between them, and to prevent deformation of the connection point under stress.

[0013] Preferably, a trapezoidal block is provided on one side of the card block, and the trapezoidal block reduces the size of one side of the card block.

[0014] The effect achieved by the above components is that by fixing the trapezoidal block on the block, the size of one side of the block is reduced, making it easier for the block to be inserted into the through hole of the first slide rail.

[0015] Preferably, the auxiliary component includes a second slide rail, a connecting block, and a baffle. The second slide rail is disposed on one side of the first slide rail, and the connecting block moves the baffle inside the second slide rail. The baffle blocks and limits the movement of the locking block.

[0016] The effect achieved by the above components is as follows: after the card block is inserted into the through hole on one side of the first slide rail, the baffle is moved so that the connecting block fixed to the baffle slides inside the second slide rail. Then the baffle reaches the side of the card block away from the first slide rail to block and limit the card block. By using the auxiliary components, the card block can be blocked to prevent the card block from being dislodged from the first slide rail, thereby improving the use effect of the card block.

[0017] Preferably, a plurality of anti-slip blocks are provided on both sides of the baffle, and the plurality of anti-slip blocks increase the friction of the baffle.

[0018] The effect achieved by the above components is to increase the friction between the operator and the baffle by fixing the anti-slip block to the baffle, making the baffle easier to move.

[0019] Preferably, a stabilizing rod is provided inside the second slide rail, and the stabilizing rod passes through the connecting block to improve stability when moving inside the slide rail.

[0020] The effect achieved by the above components is that by fixing the stabilizing rod inside the second slide rail and making the stabilizing rod slidably connected to the connecting block, the connecting block can move more stably inside the second slide rail.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a protective device, the movable plate can be moved only to the preset maximum position, and the electric telescopic rod inside the bed can be shut off by the controller, thus preventing injury to the user and improving the effectiveness of the lumbar traction device.

[0023] By using auxiliary components, the block can be blocked, preventing it from detaching from the first slide rail under force, thereby improving the block's performance. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figures 1 to 4 The lumbar traction device shown includes a bed frame 1, a controller 2 on one side of the bed frame 1, a movable plate 3 at the upper end of the bed frame 1, and straps 4 on one side of both the bed frame 1 and the movable plate 3. Protective devices 5 are installed on both sides of the bed frame 1. The protective devices 5 limit the maximum displacement of the movable plate 3 by using locking blocks 53 to restrict the sliding block 54 inside the first slide rail 51, thus protecting the user. During lumbar traction, the maximum displacement distance of the movable plate 3 is adjusted using the protective devices 5. The user lies on the bed frame 1, and the straps 4 secure the user's chest and hips. The controller 2 then activates an electric telescopic rod inside the bed frame 1, which moves the movable plate 3 along the surface of the bed frame 1, thereby moving the straps 4 around the hips to traction the user's lumbar spine. The electric telescopic rod is self-locking and can be model DYTZ450- / 50.

[0033] Figures 1 to 4The protective device 5 shown includes a first slide rail 51, a locking block 53, and a sliding block 54. The first slide rail 51 is located on the side of the bed body 1 near the moving plate 3. Several through holes 52 are opened on one side of the first slide rail 51. The locking block 53 is inserted into the through holes 52 on the surface of the first slide rail 51 to limit the sliding block 54. One side of the sliding block 54 is fixed to the moving plate 3 and moves inside the first slide rail 51. Before using the movable plate 3, insert the locking block 53 into the appropriate through hole 52 on one side of the first slide rail 51 on the surface of the bed 1. Then, the movement distance of the sliding block 54 inside the slide rail is limited. When the movable plate 3 moves on the bed 1, it will drive the sliding block 54 fixed on one side to move. Then, the sliding block 54 slides inside the first slide rail 51. After the sliding block 54 moves to the locking block 53, it blocks the locking block 53, and then the movable plate 3 stops moving. Then, the user can stop the electric telescopic rod inside the bed 1 and lock it through the controller 2, so that the movable plate 3 is no longer moved and the position after movement is guaranteed. By using the protective device 5, the movable plate 3 can only move to the preset maximum position. The electric telescopic rod inside the bed 1 can be closed through the controller 2 to avoid injury to the user, thereby improving the effect of the lumbar traction device.

[0034] Figures 1 to 4 A buffer block 55 is provided on the side of the sliding block 54 near the locking block 53. The buffer block 55 cushions the force applied to the sliding block 54 and the locking block 53. By fixing the buffer block 55, which is a rubber block, on one side of the sliding block 54, damage to the locking block 53 is reduced when the sliding block 54 contacts the locking block 53. A reinforcing plate 56 is provided between the sliding block 54 and the moving plate 3, which increases the connection strength between the two. By fixing the reinforcing plate 56 between the sliding block 54 and the moving plate 3, the connection strength is increased, and deformation at the connection point is prevented. A trapezoidal block 57 is provided on one side of the locking block 53, which reduces the size of one side of the locking block 53. By fixing the trapezoidal block 57 on the locking block 53, the size of one side of the locking block 53 is reduced, making it easier for the locking block 53 to be inserted into the through hole 52 of the first slide rail 51.

[0035] Figures 1 to 4The auxiliary component 6 shown includes a second slide rail 61, a connecting block 62, and a baffle 63. The second slide rail 61 is disposed on one side of the first slide rail 51. The connecting block 62 moves the baffle 63 inside the second slide rail 61, and the baffle 63 blocks and limits the locking block 53. After the locking block 53 is inserted into the through hole 52 on one side of the first slide rail 51, the baffle 63 is moved, causing the connecting block 62, which is fixed to the baffle 63, to slide inside the second slide rail 61. Then, the baffle 63 reaches the side of the locking block 53 away from the first slide rail 51, thereby blocking and limiting the locking block 53. By using the auxiliary component 6, the locking block 53 can be blocked, preventing the locking block 53 from being dislodged from the first slide rail 51 by force, thus improving the usability of the locking block 53.

[0036] Figures 1 to 4 The baffle 63 shown has several anti-slip blocks 64 on both sides, which increase the friction of the baffle 63. By fixing the anti-slip blocks 64 to the baffle 63, the friction between the operator and the baffle 63 is increased, making the baffle 63 easier to move. A stabilizing rod 65 is provided inside the second slide rail 61, passing through the connecting block 62, to improve stability when moving within the slide rail. By fixing the stabilizing rod 65 inside the second slide rail 61 and making the stabilizing rod 65 slidably connected to the connecting block 62, the connecting block 62 moves more stably within the second slide rail 61.

[0037] Working principle: When performing lumbar traction, the maximum displacement distance of the moving plate 3 is adjusted by the protective device 5. Then, the user lies on the bed 1, and the straps 4 are used to fix the user's chest and hips. Then, the controller 2 causes the electric telescopic rod inside the bed 1 to move the moving plate 3 along the surface of the bed 1, which in turn moves the straps 4 around the hips to perform lumbar traction on the user. Before using the movable plate 3, insert the locking block 53 into the appropriate through hole 52 on one side of the first slide rail 51 on the surface of the bed 1. Then, the movement distance of the sliding block 54 inside the slide rail is limited. When the movable plate 3 moves on the bed 1, it will drive the sliding block 54 fixed on one side to move. Then, the sliding block 54 slides inside the first slide rail 51. After the sliding block 54 moves to the locking block 53, it blocks the locking block 53, and then the movable plate 3 stops moving. Then, the user can stop the electric telescopic rod inside the bed 1 and lock it through the controller 2, so that the movable plate 3 is no longer moved and the position after movement is guaranteed. By using the protective device 5, the movable plate 3 can only move to the preset maximum position. The electric telescopic rod inside the bed 1 can be closed through the controller 2 to avoid injury to the user, thereby improving the effect of the lumbar traction device.

[0038] After the locking block 53 is inserted into the through hole 52 on one side of the first slide rail 51, the baffle 63 is moved so that the connecting block 62 fixed to the baffle 63 slides inside the second slide rail 61. Then the baffle 63 reaches the side of the locking block 53 away from the first slide rail 51 to block and limit the locking block 53. By using the auxiliary component 6, the locking block 53 can be blocked to prevent the locking block 53 from being dislodged from the first slide rail 51 by force, thereby improving the use effect of the locking block 53.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
