Description

Technical Field

[0001] This utility model relates to the field of traction and stretching equipment, and in particular to a foldable traction and stretching bed for the cervical and lumbar spine. Background Technology

[0002] The human body is subject to long-term effects from its own weight, aging, and other external forces, pressures, and occupational habits, which can cause compression or bending deformation between the joints supporting the spine and other parts of the body, easily leading to various cervical and lumbar spondylosis. Because traction and stretching therapy has the advantages of being non-invasive, having few side effects, and relatively good efficacy, it has become the preferred method for treating cervical and lumbar spondylosis for more and more users.

[0003] However, existing traction and stretching beds are bulky, inconvenient to move and store, and difficult to use at home, making it difficult for users to perform traction and stretching exercises at home anytime. To solve the above technical problems, the applicant previously applied for Chinese utility model patent CN218900696U, which provides a portable folding exercise bed. This exercise bed can be folded and stored, thereby reducing the overall space occupied by the exercise bed and facilitating its storage and use at home.

[0004] However, after the applicant transformed the above-mentioned patented technical solution into a product, it was found that the above-mentioned technical solution still had the following technical problems: the portable folding fitness bed can only traction and stretch the lumbar spine, but cannot traction and stretch the cervical spine, and cannot meet the different needs of users; and the foot limiting component of the fitness bed can only adjust the height position of the presser foot limiting roller, but cannot adjust it in the length direction, so it cannot be used for users of different heights; furthermore, whether locking or unlocking the second support member to the base, the user needs to rotate the unlocking plates on both sides simultaneously with both hands to make the locking part of the locking plate be in or out of the fixing hole, which is inconvenient to operate, especially when unlocking, it is difficult for the user to rotate the unlocking plate to the bottom of the horizontal part of the locking plate. Utility Model Content

[0005] In order to solve one or more technical problems in the prior art, or at least provide a beneficial alternative, this utility model provides a foldable traction and stretching bed for the cervical and lumbar spine. In addition to being foldable and storable, it can not only perform traction and stretching of the cervical and lumbar spine, but also has an adjustable length foot limiting mechanism to suit users of different heights.

[0011] Furthermore, multiple first adjustment holes are respectively provided on both sides of the first support member in an array, and the movable limiting member and the second height adjustment component are respectively detachably plugged into the first adjustment holes.

[0012] Furthermore, the head limiting roller assembly includes a head limiting roller and a mounting frame. The mounting frame includes a horizontal crossbar and vertical bars disposed on both sides of the horizontal crossbar. The head limiting roller is disposed in the middle of the horizontal crossbar. The second height adjustment assembly consists of two sets. Each set of the second height adjustment assembly includes a plug rod, an adjusting rod, and a third fixing structure. The plug rod is detachably inserted into the first support member. The adjusting rod is slidably connected to the plug rod. The third fixing structure is used to lock the relative position between the adjusting rod and the plug rod. The vertical bar is hinged to the adjusting rod.

[0013] Furthermore, a head support plate is hinged to one end of the first support member away from the base, and a storage groove is provided at the bottom of the first support member, into which the head support plate can rotate; a plurality of folding support members for support are installed at the bottom of the first support member and the bottom of the head support plate, and a plurality of second rollers are installed at the bottom of the base and the second support member respectively.

[0014] Furthermore, at least one fixing hole is provided on each side of the base near the end of the first support member; the locking mechanism includes a control link and movable hooks, the control link is rotatably disposed at the bottom of the second support member near the end of the first support member, at least one end of the control link passes through the second support member and is fixedly connected to a driving member, there are two movable hooks respectively rotatably disposed on both sides of the bottom of the second support member, the movable hooks can engage with the fixing holes, two driving blocks are fixedly connected on the control link corresponding to the positions of the two movable hooks, and each movable hook is provided with a driving groove that engages with the driving block.

The number of locking plates is the same as the reset spring. The locking plates are inserted horizontally into the locking slots and slide in cooperation with the locking rod.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) By setting a first length adjustment component and a first height adjustment component in the foot limiting mechanism, the position of the presser foot limiting roller assembly along the length direction of the traction stretching bed can be adjusted according to the user's height, which can be well adapted to users of different heights. In addition, the height position of the upper roller group relative to the lower roller group can be adjusted according to the thickness of the user's foot, thus adapting to users with different foot thicknesses and effectively expanding the application range of the traction stretching bed.

[0019] (2) A head limiting mechanism is also provided, which includes a head limiting roller assembly and a second height adjustment assembly. The head limiting roller assembly is detachably mounted on the first support member through the second height adjustment assembly. This allows the traction stretching bed to simultaneously perform traction stretching on the cervical and lumbar vertebrae during the traction stretching process. When traction stretching of the cervical vertebrae is not required, the head limiting roller assembly can be detached from the first support member, making it flexible to use.

[0020] (3) By setting a control linkage, when it is necessary to lock or unlock the second support and the base, the user only needs to rotate one side of the drive component with one hand. The drive component drives the control linkage to rotate, thereby driving the drive block to rotate. The drive block drives the movable hook to rotate, thereby making the movable hook engage or disengage from the fixing hole, realizing the locking and unlocking between the second support and the base. There is no need to operate with both hands at the same time, and the operation is simple and convenient.

[0021] (4) By setting the first magnetic component and the second magnetic component, when it is necessary to lock the second support component and the base, the arms apply force to the two movable limiting components and / or the feet apply force to the foot limiting mechanism, thereby driving the second support component to move towards the first support component against the elastic force of the return spring. At this time, the first magnetic component moves towards the second magnetic component along with the second support component. When the first magnetic component moves to a certain position, the first magnetic component is attracted to the second magnetic component, thereby driving the control linkage to rotate. At this time, the rotation direction of the control linkage can drive the end of the drive block away from the control linkage to rotate towards the base, thereby driving the movable hook to rotate towards the base as well, so that the movable hook is engaged in the fixing hole, thereby realizing the locking between the second support component and the base. That is, by setting the first magnetic component and the second magnetic component, the locking between the second support component and the base can be realized without the need for the hands to perform any operation on the drive component.

[0037] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0038] This application discloses a foldable traction and stretching bed for the cervical and lumbar spine. For example... Figure 1-3As shown, the device includes a base 1, a first support member 2, and a second support member 3. The base 1 is roughly rectangular, while the first and second support members 2 and 3 are both roughly rectangular plates. One end of the first support member 2 is hinged to one end of the base 1. The second support member 3 is located on top of the base 1 and slides in conjunction with it. The first support member 2 can be flipped to the top of the second support member 3. At this point, the side of the first support member 2 facing the base 1 is its top surface, and the side away from the base 1 is its bottom surface. Flipping the first support member 2 allows the traction stretching bed to be folded, effectively reducing its overall volume and facilitating storage. Support columns 28 are provided on both sides of the top surface of the first support member 2 at the end away from the base 1. When the first support member 2 is flipped and folded to the top surface of the second support member 3, the support columns 28 support the first support member 2. Figure 11 As shown, a plurality of first rollers 31 are provided on both sides of the second support member 3. The plurality of first rollers 31 are in contact with both sides of the base 1. The second support member 3 is supported on the top of the base 1 by the plurality of first rollers 31, which helps to reduce the frictional resistance when the second support member 3 moves relative to the base 1.

[0039] See Figure 5 , 7 -10, the second support member 3 is equipped with a foot limiting mechanism, which includes a first length adjustment component, a first height adjustment component, and a presser foot limiting roller assembly 34. The presser foot limiting roller assembly 34 includes an upper roller group 341 and a lower roller group 342. The lower roller group 342 is connected to the second support member 3 via the first length adjustment component, and the upper roller group 341 is positioned above the lower roller group 342 via the first height adjustment component. In this embodiment, by providing the first length adjustment component and the first height adjustment component in the foot limiting mechanism, the position of the presser foot limiting roller assembly 34 along the length direction of the traction stretching bed can be adjusted according to the user's height, making it suitable for users of different heights. Furthermore, the height position of the upper roller group 341 relative to the lower roller group 342 can be adjusted according to the thickness of the user's feet, thus making it suitable for users with feet of different thicknesses and effectively expanding the applicability of the traction stretching bed in this embodiment.

[0040] Preferably, such as Figure 7-8As shown, the first length adjustment assembly includes a fixed sleeve 41, a movable sleeve 42, and a first fixing structure. The fixed sleeve 41 is fixedly connected to the bottom of the second support member 3. The movable sleeve 42 is slidably disposed inside the fixed sleeve 41 to achieve a slidable connection with the fixed sleeve 41. The lower roller group 342 is fixed to the end of the movable sleeve 42 away from the fixed sleeve 41 by a connecting seat 49. The lower roller group 342 includes two lower rollers, which are symmetrically disposed on both sides of the connecting seat 49. The first fixing structure is used to lock the relative position between the movable sleeve 42 and the fixed sleeve 41. Specifically, the first fixing structure includes a snap-fit ​​member 43, a pressing member 44, a first snap-fit ​​through hole 45 disposed at the bottom of the fixed sleeve 41, and a plurality of second snap-fit ​​through holes 46 disposed at the bottom of the movable sleeve 42 along the length direction of the movable sleeve 42. The first snap-fit ​​through hole 45 can be aligned with one of the second snap-fit ​​through holes 46. The snap-fit ​​member 43 is provided with a rotating shaft at one end away from the first snap-fit ​​through hole 45. The snap-fit ​​member 43 is rotatably disposed in the fixed sleeve 41 via the rotating shaft. The snap-fit ​​member 43 is provided with a snap-fit ​​hook 47 at one end near the first snap-fit ​​through hole 45, which engages with the first snap-fit ​​through hole 45 and the second snap-fit ​​through holes 46. The pressing member 44 is connected to the end of the snap-fit ​​member 43 away from the first snap-fit ​​through hole 45. Both the fixed sleeve 41 and the second support member 3 are provided with clearance through holes 48 to avoid the pressing member 44. In actual use, since the rotating shaft is located close to the pressing member 44, under the action of gravity, the locking hook 47 is close to the bottom of the fixed sleeve 41 and is engaged in the first locking through hole 45 and the second locking through hole 46. The pressing member is close to the top of the fixed sleeve 41 and extends into the clearance through hole 48 of the second support member 3. When it is necessary to adjust the relative position between the movable sleeve 42 and the fixed sleeve 41, the user presses the pressing member 44 in the clearance through hole 48 of the second support member 3, causing the locking hook 47 to move upward and disengage from the first locking through hole 45 and the second locking through hole 46. At this time, the movable sleeve 42 is moved to a suitable position so that the other second locking through hole 46 is aligned with the first locking through hole 45. The pressing force on the pressing member 44 is released, and the locking hook 47 moves downward and engages in the first locking through hole 45 and the second locking through hole 46 due to gravity, thus relocking the relative position between the movable sleeve 42 and the fixed sleeve 41. Of course, in some other embodiments, the first fixing structure can also be other forms of fixing structure, as long as it can lock the relative position between the movable sleeve 42 and the fixed sleeve 41, which will not be elaborated here.

[0041] Preferably, see Figure 8-9The first height adjustment assembly includes a first sleeve 51, a second sleeve 52, and a second fixing structure. The first sleeve 51 is connected to the connecting seat 49. The second sleeve 52 is slidably disposed within the first sleeve 51 to achieve a slidable connection with the first sleeve 51. The upper roller assembly 341 includes two upper rollers. In this case, the first sleeve 51 has through-grooves 511 on both sides to avoid the two upper rollers. The two upper rollers in the upper roller assembly 341 pass through the through-grooves 511 and are connected to the second sleeve 52. The second fixing structure is used to lock the relative position between the second sleeve 52 and the first sleeve 51. Of course, in some other embodiments, the first sleeve 51 can also be slidably disposed within the second sleeve 52 to achieve a slidable connection with the second sleeve 52. In this case, the upper roller assembly 341 does not need to pass through the first sleeve 51 and is directly connected to the second sleeve 52. Specifically, the second fixing structure includes a fastener 53, a snap-fit ​​groove 54 disposed on the side wall of the first sleeve 51, and an oblong hole disposed on the side wall of the second sleeve 52. The snap-fit ​​groove 54 includes a straight groove 541 and a plurality of recesses 542 communicating with the straight groove 541. The oblong hole can be aligned with one of the recesses 542. The fastener 53 includes a screw and a nut. The screw passes through the oblong hole, the snap-fit ​​groove 54, and is connected to the nut in sequence. In actual use, when it is necessary to adjust the relative position between the first sleeve 51 and the second sleeve 52, the nut is loosened, the screw is moved from one recess 542 to the straight groove 541, the second sleeve 52 is moved to a suitable position so that the oblong hole is aligned with another recess 542, the screw is moved to another recess 542, the nut is tightened, and the relative position between the first sleeve 51 and the second sleeve 52 is relocked. Of course, in some other embodiments, the second fixing structure can be other forms of fixing structure, as long as it can lock the relative position between the first sleeve 51 and the second sleeve 52, which will not be elaborated here.

[0042] Furthermore, such as Figure 5 , 7As shown in Figure 8, the first sleeve 51 is rotatably connected to the connecting seat 49; the foot limiting mechanism also includes a presser foot connecting rod 33 and a presser foot adjusting rod 35. One end of the presser foot connecting rod 33 is rotatably mounted on the first sleeve 51, and the presser foot adjusting rod 35 is fixedly connected to the end of the movable sleeve 42 away from the fixed sleeve 41. The presser foot adjusting rod 35 has a plurality of presser foot adjusting holes 36 distributed along its own length direction, and the end of the presser foot connecting rod 33 away from the first sleeve 51 has a presser foot locking part 37 that engages with the presser foot adjusting hole 36. In actual use, the user places their foot between the upper roller group 341 and the lower roller group 342, with the instep abutting against the upper roller group 341 and the sole of the foot abutting against the lower roller group 342. By setting the first sleeve 51 to be rotatably connected to the connecting seat 49, on the one hand, the user can adjust the pressure foot connecting rod 33 to engage with different pressure foot adjustment holes 36 according to the comfort of placing their foot between the upper roller group 341 and the lower roller group 342, thereby adjusting the tilt angle of the first sleeve 51 and the upper roller group 341 relative to the lower roller group 342; on the other hand, when the traction stretching bed is not in use and is stored, the pressure foot locking part 37 is disengaged from the pressure foot adjustment hole 36, so that the first sleeve 51 and the upper roller group 341 are folded and placed on the surface of the second stretching member 3, further reducing the storage volume of the traction stretching bed.

[0043] See Figure 1-3 The first support member 2 is detachably provided with two movable limiting members 5. The two movable limiting members 5 are roughly cylindrical and are located on both sides of the first support member 2. When the user lies on the traction and stretching bed, the armpits on both sides abut against the two movable limiting members 5 respectively. The movable limiting members 5 limit the part of the human body above the arms. When the second support member 3 slides away from the first support member 2 relative to the base 1, the user's feet are placed in the foot limiting mechanism, so that the feet move away from the first support member 2 along with the second support member 3, so as to achieve traction and stretching of the user's lumbar spine.

[0044] For example Figure 1-3As shown in Figure 6, the traction stretching bed in this embodiment also includes a head limiting mechanism. The head limiting mechanism includes a head limiting roller assembly and a second height adjustment assembly. The head limiting roller assembly is detachably mounted on the first support member 2 via the second height adjustment assembly. Preferably, the head limiting roller assembly includes a head limiting roller 61 and a mounting frame 62. The mounting frame 62 includes a horizontal crossbar 621 in the shape of a "U" and vertical bars 622 disposed on both sides of the horizontal crossbar 621. The head limiting roller 61 is disposed in the middle of the horizontal crossbar 621. The second height adjustment assembly consists of two sets. Each set of the second height adjustment assembly includes a plug rod 63, an adjusting rod 64, and a third fixing structure. The plug rod 63 is detachably inserted into the first support member 2. The adjusting rod 64 is sleeved on the outside of the plug rod 63 to achieve a sliding connection between the adjusting rod 64 and the plug rod 63. The third fixing structure is used to lock the relative position between the adjusting rod 64 and the plug rod 63. The vertical bar 622 is hinged to the adjusting rod 64. Specifically, both the vertical rod 622 and the adjusting rod 64 are hollow square tubes. The adjusting rod 64 has two symmetrically arranged first lugs 641 on its top left and right sides, and the vertical rod 622 has two symmetrically arranged second lugs 623 on its left and right sides near the end of the adjusting rod 64. The first lugs and the corresponding second lugs 623 are connected by a pivot. The top surfaces of the front and rear sides of the adjusting rod 64 form a stop surface 642. When the vertical rod 622 rotates to a position approximately perpendicular to the adjusting rod 64, the stop surface 642 engages with the outer wall of the vertical rod 622, keeping the vertical rod 622 in a position approximately perpendicular to the adjusting rod 64. The third fixing structure can be the same as the second fixing structure, or it can be another type of fixing structure, as long as it can lock the relative position between the adjusting rod 64 and the insertion rod 63. Further details are omitted here. In actual use, the user inserts the connector 63 into the appropriate position on the first support 2 according to the position of their chin when lying on the traction bed. Then, according to the height of the chin, the user adjusts the relative position between the adjusting rod 64 and the connector 63. Before the user lies down, the vertical rod 622 is rotated to the side away from the second support 3. Figure 1 As shown, this allows the head-limiting roller 61 to avoid the user's head, enabling the user to lie down smoothly; after the user lies down, the drive rod 622 rotates 180° to the side closer to the second support member 3, as shown. Figure 2As shown, the vertical rod 622 crosses the user's face, so that the head-limiting roller 61 is exactly abutting the user's chin. When the second support member 3 moves the user's feet away from the first support member 2 relative to the base 1, the head-limiting roller 61 limits the head, achieving traction and stretching of the cervical spine. Therefore, the traction and stretching bed in this embodiment can simultaneously perform traction and stretching of the cervical and lumbar spine during the traction and stretching process. When traction and stretching of the cervical spine is not required, it is not necessary to rotate the vertical rod 622 to the side closer to the second support member 3, or the head-limiting mechanism can be detached from the first support member 2, making it flexible to use. Furthermore, when the traction and stretching bed is not in use and needs to be stored, the head-limiting mechanism can also be removed for storage, further reducing the storage volume of the traction and stretching bed. Furthermore, a headrest 65 can be placed between the two sets of second height adjustment components to support the user's head, increasing the comfort of use.

[0045] See Figure 1-3 The first support member 2 has multiple first adjustment holes 4 arranged in an array on both sides. The movable limiting member 5 and the plug rod 63 of the second height adjustment component are detachably plugged into the first adjustment holes 4.

[0046] For example Figure 1-3 As shown in Figures 5 and 10, a head support plate 7 is hinged to the end of the first support member 2 away from the base 1. Specifically, the head support plate 7 is hinged to the bottom of the first support member 2 via a hinge. A storage groove 8 is provided at the bottom of the first support member 2, allowing the head support plate 7 to rotate into the storage groove 8 for easy folding and storage. To facilitate removal of the head support plate 7 from the storage groove 8, a retrieval slot 9 communicating with the storage groove 8 is provided at the bottom of the first support member 2. In actual use, when traction and stretching are required, the head support plate 7 is removed from the storage groove 8 and rotated to a position flush with the first support member 2, thus providing stable support for the user's head. When the traction and stretching bed is not in use and needs to be stored, the head support plate is rotated into the storage groove 8, further reducing the storage volume of the traction and stretching bed. Furthermore, as... Figure 10 As shown, the bottom of the first support member 2 and the bottom of the head support plate 7 are each equipped with a plurality of folding support members 10 for support. The bottom of the first support member 2 and the bottom of the head support plate 7 are each provided with a plurality of receiving slots 11 for accommodating the folding support members 10. When the traction stretching bed is in use, the folding support members 10 are removed from the receiving slots 11 to support the first support member 2 and the head support plate 7, ensuring that the first support member 2, the head support plate 7, and the second support member 3 are at the same horizontal level. When the traction stretching bed is not in use and is being stored, the folding support members 10 can be folded and stored in the receiving slots 11, effectively reducing the storage volume of the traction stretching bed. Specifically, see [link to documentation]. Figure 11 The folding support 10 includes a mounting base 101, a fixing part 102, and a locking part 103. The mounting base 101 of each set of folding support 10 is fixedly installed at the bottom of each receiving groove 11 by screws. The fixing part 102 and the locking part 103 are rotatably connected to the mounting base 101 via a rotating shaft, and both the fixing part 102 and the locking part 103 can be rotatably stored within the receiving groove 11, so that the receiving groove 11 can accommodate and store the folding support 10. The locking part 103... When the fixing part 102 is located in the receiving groove 11, the locking part 103 is arranged perpendicular to the fixing part 102. A fixing groove 12 is provided on one side of the locking part 103. When the locking part 103 and the fixing part 102 are rotated to a state perpendicular to the mounting base 101, the fixing part 102 is located in the fixing groove 12, so that the locking part 103 plays a limiting role in the position of the fixing part 102, thereby enabling the fixing part 102 to achieve stable support for the first support member 2 and the head support plate 7.

[0047] For example Figure 10 As shown, the bottom of the base 1 and the second support member 3 are each equipped with a number of second rollers 14. The second rollers 14 contact the ground to support the base 1 and the second support member 3, so that the traction stretch bed can be easily pushed to change the position of the traction stretch bed. For example, when the traction stretch bed is stored, it can be easily pushed under the sofa at home.

[0048] When the traction stretching bed is folded for storage, only the second roller 14 provides support. If someone stands on it, especially a child playing on it, the bed is prone to shifting under stress, potentially causing the person standing on it to fall or have other accidents. Therefore, refer to... Figure 5 , 1012. Two sets of support rods 22 are rotatably connected to the bottom of the base 1, with two support rods 22 distributed along the length of the base 1. The base 1 has four rectangularly distributed limiting grooves 23, and each support rod 22 is located in one of the limiting grooves 23. The base 1 is provided with two supporting connecting rods 24, and the two support rods 22 of each set are rotatably installed on the two supporting connecting rods 24, so that the supporting connecting rods 24 synchronously drive the two support rods 22 to move, which facilitates the support rods 22 to quickly and stably support the base 1. Furthermore, each supporting connecting rod 24 is fixedly connected to a drive rod 25. The base 1 has two drive sliding grooves 26, and the two drive rods 25 pass through the two drive sliding grooves 26 and slide in cooperation with the drive sliding grooves 26. When the drive rods 25 slide in the drive sliding grooves 26 to both ends of the drive sliding grooves 26, the supporting connecting rods 24 drive the two support rods 22 to rotate out or into the limiting grooves 23, which further facilitates the rotation of the support rods 22 by the operator. When the traction stretching bed is folded and stored, the drive rod 25 slides in the drive groove 26, thereby causing each support rod 22 to rotate out of the limiting groove 23. At this time, the bottom of the support rod 22 is lower than the bottom of each second roller 14, so that the support rod 22 supports the traction stretching bed. At this time, each second roller 14 does not contact the ground, thereby ensuring that the traction stretching bed is placed stably and preventing accidents of people falling.

[0049] See Figure 3-4 10, 12, A plurality of horizontally arranged return springs 15 are installed between the base 1 and the second support member 3. One end of each return spring 15 is fixedly connected to the base 1. Specifically, the base 1 is fixedly installed with guide tubes 16 in the same number as the return springs 15. The guide tubes 16 are also arranged parallel to each other. Each return spring 15 passes through each guide tube 16 to ensure the stability of the return spring 15 during its extension and retraction. The base 1 is fixedly connected with a horizontally arranged mounting rod 17. Each guide tube 16 passes through the mounting rod 17 and is arranged perpendicular to the mounting rod 17. The mounting rod 17 further limits the position of each guide tube 16, thereby helping to ensure the stability of the position of each guide tube 16. See also Figure 3-4Preferably, the second support member 3 is provided with a locking assembly connected to the return spring 15. The locking assembly includes a locking rod 18 and a locking plate 19. The locking rod 18 is fixedly connected to the second support member 3. The locking rod 18 has locking slots 20, the same number as the return springs 15, extending through it. The other end of each return spring 15 corresponds to and can extend into the locking slot 20. The number of locking plates 19 is the same as the number of return springs 15, and the locking plates 19 are horizontally inserted into the locking slots 20 and slide in cooperation with the locking rod 18. Further, the locking plate 19 includes a locking part 191 and an unlocking part 192. The unlocking part 192 is fixedly connected to the locking part 191 and is perpendicular to the locking part 191. Each locking part 191 is horizontally inserted into the locking slot 20 and slides in cooperation with the locking rod 18. The locking rod 18 has several unlocking slots 21 for each unlocking part 192 to extend horizontally. When each unlocking part 192 slides in the unlocking slot 21, each locking part 191 slides horizontally in the locking slot 20. When the return spring 15 is inserted into each locking slot 20, the connection between the return spring 15 and the second support member 3 can be achieved by moving the unlocking part 192 so that the locking part 191 is inserted into the locking slot 20. This allows the user to install different numbers of return springs 15 for traction and stretching according to their own needs.

[0050] like Figure 3 , 12As shown in Figure -15, the second support member 3 is provided with a locking mechanism that can be fixed or not fixed to the base 1. At least one fixing hole 27 is provided on each side of the base 1 near the end of the first support member 2. The locking mechanism includes a control link 71 and movable hooks 72. The control link 71 is rotatably disposed at the bottom of the second support member 3 near the end of the first support member 2. At least one end of the control link 71 passes through the second support member 3 and is fixedly connected to a driving member 73. Specifically, both ends of the control link 71 pass through the second support member 3 and are fixedly connected to driving members 73 at both ends. There are two movable hooks 72, which are rotatably disposed on both sides of the bottom of the second support member 3. The movable hooks 72 can engage with the fixing holes 27. Two driving blocks 74 are fixedly connected to the control link 71 corresponding to the positions of the two movable hooks 72. Each movable hook 72 is provided with a driving groove 75 that engages with the driving block 74. By setting the control linkage 71, when it is necessary to lock or unlock the second support member 3 and the base 1, the user only needs to rotate one side of the drive member 73 with one hand. The drive member 73 drives the control linkage 71 to rotate, thereby driving the drive block 74 to rotate. When the end of the drive block 74 away from the control linkage 71 rotates towards the base 1, it will drive the movable hook 72 to rotate towards the base 1 as well, so that the movable hook 72 can be engaged in the fixing hole 27, thereby locking the second support member 3 and the base 1. When the end of the drive block 74 away from the control linkage 71 rotates away from the base 1, it will drive the movable hook 72 to rotate away from the base 1 as well, so that the movable hook 72 can be disengaged from the fixing hole 27, thereby unlocking the second support member 3 and the base 1. The locking mechanism of this embodiment can lock or unlock the second support member 3 and the base 1 with only one hand, without the need for both hands to operate at the same time, making the operation simple and convenient.

[0051] For example Figure 14As shown, the locking mechanism further includes at least one first magnetic element 76 fixedly mounted on the control linkage 71, and at least one second magnetic element 77 fixedly mounted on one end of the base 1 near the first support member 2. The first magnetic element 76 and the second magnetic element 77 are magnetically attracted to each other. Specifically, there are two first magnetic elements 76 and two second magnetic elements 77, and the two first magnetic elements 76 and the two second magnetic elements 77 are symmetrically arranged on both sides of the central axis of the traction and stretching bed. In actual use, when the traction and stretching is completed and it is necessary to lock the second support member 3 and the base 1, the arms apply force to the two movable limiting members 5 and / or the feet apply force to the foot limiting mechanism, thereby driving the second support member 3 to move towards the first support member 2 against the elastic force of the return spring 15. At this time, the first magnetic element 76 follows the second support member 3 to move towards the first support member 2, that is, the first magnetic element 76 moves towards the second magnetic element 77. When the first magnetic element 76 moves to a certain position, a sufficiently large magnetic attraction force is generated between the first magnetic element 76 and the second magnetic element 77. The magnetic component 76 will be attracted to the second magnetic component 77, thereby causing the control linkage 71 to rotate. At this time, the rotation direction of the control linkage 71 can drive the end of the drive block 74 away from the control linkage 71 to rotate towards the base 1, thereby driving the movable hook 72 to rotate towards the base 1 as well, so that the movable hook 72 can be engaged in the fixing hole 27, realizing the locking between the second support component 3 and the base 1; that is, by setting the first magnetic component 76 and the second magnetic component 77, the locking between the second support component 3 and the base 1 can be achieved without any operation of the drive component 73 by both hands. When it is necessary to unlock the second support member 3 from the base 1, the user only needs to rotate the drive member 73 on one side with one hand. The drive member 73 drives the control linkage 71 to rotate, thereby driving the drive block 74 and the first magnetic member 76 to rotate. At this time, the end of the drive block 74 away from the control linkage 71 rotates away from the base 1, and the first magnetic member 76 rotates away from the second magnetic member 77. The drive block 74 will drive the movable hook 72 to rotate away from the base 1 as well, thereby causing the movable hook 72 to disengage from the fixing hole 27, thus unlocking the second support member 3 from the base 1.

[0052] The implementation principle of a foldable traction and stretching bed for the cervical and lumbar spine according to an embodiment of this application is as follows: When the traction and stretching bed is used for the first time in a folded state, the other ends of several return springs 15 are not connected to the second support member 3, and the return springs 15 are in a reset state; firstly, remove the folded support member 10 at the bottom of the first support member 2, and flip the first support member 2 to a state flush with the second support member 3; then, rotate the drive member 73 on one side with one hand to drive the control linkage 71 to rotate, thereby driving the drive block 74 and the first magnetic member 76 to rotate, so that the movable hook 72 disengages from the fixing hole 27, at which point the second support member 3 and the base 1 are in an unlocked state without fixing; then, push the second support member 3 away from the first support member 2, so that the other ends of several return springs 15 extend into the corresponding locking slots 20. The user can select an appropriate number of locking plates 19 to insert into the other ends of the corresponding number of return springs 15 according to their own situation, so that the appropriate The other end of the return spring 15 is connected to the second support 3, so that a suitable traction force can be applied to the user during subsequent use. Then, the side of the first support 2 away from the base 1 is blocked and limited by a wall or an object of a certain weight, pushing the second support 3 to move closer to the first support 2 against the elastic force of the return spring 15, until the first magnetic component 76 is attracted to the second magnetic component 77, which drives the movable hook 72 to engage in the fixing hole 27, thereby locking the second support 3 and the base 1. Then, the first length adjustment component, the first height adjustment component, and the presser foot connecting rod 33 are adjusted to the appropriate position, and the movable limiting component 5 and the second height adjustment component are inserted into the appropriate position, and then the second height adjustment component is adjusted to the appropriate position. Then, the head support plate 7 and the folding support component 10 at its bottom are taken out, and the head support plate 7 is flipped to a horizontal state, so that the traction and stretching bed can be moved to different positions for use.In use, the user lies flat between the two movable limiting members 5, with their armpits abutting against the two movable limiting members 5, and their feet inserted between the upper roller group 341 and the lower roller group 342. If cervical traction and stretching are required simultaneously, the mounting bracket 62 is inserted into the second height adjustment component. Rotating one side of the drive member 73 with one hand drives the control linkage 71 to rotate, thereby driving the drive block 74 and the first magnetic member 76 to rotate, causing the movable hook 72 to disengage from the fixing hole 27. At this time, the second support member 3 and the base 1 are in an unlocked state without being fixed. The second support base 3 moves away from the first support member 2 under the restoring force of the return spring 15. Since the user's feet are placed in the foot limiting mechanism, the feet move away from the first support member 2 along with the second support member 3. And since the armpits on both sides abut against the two movable limiting members 5 respectively, and the chin abuts against the head limiting roller 61, from This achieves traction and stretching of the user's cervical and lumbar spine. After traction and stretching are completed, the arms apply force to the two movable limiting members 5 and / or the feet apply force to the foot limiting mechanism, thereby driving the second support member 3 to move towards the first support member 2 against the elastic force of the return spring 15. At this time, the first magnetic member 76 follows the second support member 3 and moves towards the second magnetic member 77. When the first magnetic member 76 moves to a certain position, it is attracted to the second magnetic member 77, thereby driving the control linkage 71 to rotate. At this time, the rotation direction of the control linkage 71 can drive the end of the drive block 74 away from the control linkage 71 to rotate towards the base 1, thereby driving the movable hook 72 to rotate towards the base 1 as well, so that the movable hook 72 can be engaged in the fixing hole 27, realizing the locking between the second support member 3 and the base 1, thus completing the traction and stretching of the cervical and lumbar spine. If cervical traction and stretching is not required, the head limiting mechanism is not required. After use, the traction stretching bed can be folded and stored to reduce space usage. If the traction stretching bed is used frequently, drive the movable hook 72 to engage with the fixing hole 27 to lock the second support 3 with the base 1, remove the movable limiter 5 and the head limiter mechanism, fold the first sleeve 51 and the upper roller group 341, and then flip and fold the first support 2 and the head support plate 7 in sequence, and fold the folded support 10 into the receiving groove 11 for storage. When using it again, simply flip and install each part in sequence.If the traction stretching bed is not used for a short period of time, remove the movable limiting piece 5 and the head limiting mechanism, fold the first sleeve 51 and the upper roller group 341, drive the movable hook 72 to disengage from the fixing hole 27 so that the second support piece 3 is unlocked from the base 1. Under the elastic force of the return spring, the second support piece 3 moves away from the first support piece 2. When the second support piece 3 moves to the state where the return spring is not stretched, the movable locking plate 19 unlocks the return spring 15 from the second support piece 3. Then move the second support piece 3 so that it resets to the position close to the first support piece 2 and locks with the base 1. Then flip and fold the first support piece 2 and the head support plate 7 in sequence, and fold the folded support piece 10 into the receiving groove 11 for storage. When using it again, follow the same steps as when using it for the first time.
