DETAILED DESCRIPTION

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0037] like Figure 2 , Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, the upper surface of the bottom plate 1 is slidably connected with a threaded plate 12 and a third support plate 15, and the third support plate 15 is fixedly connected to the right side of the first support plate 4, and the third support plate 15 is connected to the threaded plate 12 by a self-locking mechanism, and the self-locking mechanism includes a first movable plate 16 slidably connected to the upper surface of the third support plate 15, and two symmetrical connecting plates 45 are slidably connected inside the first movable plate 16, and the two side surfaces of the connecting plate 45 are respectively fixedly connected with a second movable plate 17 and a first wedge plate 18, and the two first wedge plates 18 are fixedly connected with a second spring 39 on the sides away from each other, and the two second springs 39 are fixedly connected with a fourth support plate 21 on the ends away from each other, and the two fourth support plates 21 are fixedly connected to the left side of the first movable plate 16, and a through groove adapted to the connecting plate 45 is provided inside the first movable plate 16. When the first wedge plate 18 moves outward, it can drive the connecting plate 45 and the second movable plate 17 to move accordingly and compress the second spring 39.

[0038] like Figure 5 , Fig. 9 and Fig.10The left side of the threaded plate 12 shown is fixedly connected to two first fixed plates 13, and the sides of the two first fixed plates 13 that are away from each other are fixedly connected to the first limiting rod 14. The interiors of the two second movable plates 17 are provided with a strip groove 19 and a plug hole 20 that are adapted to the first limiting rod 14, and the plug hole 20 is located at the right end of the strip groove 19 and is connected to the strip groove 19. The upper surface of the third support plate 15 is fixedly connected to the fifth support plate 22, and the side of the fifth support plate 22 close to the first movable plate 16 is fixedly connected to the first wedge plate 18. The second wedge block 23 corresponds to the first wedge plate 18 one by one. The left side of the threaded plate 12 is fixedly connected with a strip plate 31. The outer surface of the rotating shaft 6 is fixedly connected with a gear 33. The strip plate 31 is integrally formed with teeth 32 adapted to the gear 33. The upper surface of the bottom plate 1 is fixedly connected with a baffle 34 for blocking the first support plate 4. When the second bed board 3 is in a horizontal state, the first limit rod 14 is always inserted into the inside of the plug hole 20. At this time, the movement of the threaded plate 12 can drive the second movable plate 17 and the first movable plate 1 6 and the first wedge plate 18 move accordingly. When the second bed board 3 is in the initial state, the baffle 34 can block the first support plate 4 to prevent it from moving to the left. At this time, if the threaded plate 12 is driven to move to the left, since the first support plate 4, the third support plate 15 and the second wedge block 23 are in a relatively fixed state, when the second moving plate 17, the first moving plate 16 and the first wedge plate 18 move horizontally to the left, the second wedge block 23 will squeeze the first wedge plate 18 to slide outward, and the movement of the first wedge plate 18 can drive the second moving plate 17, the first moving plate 16 and the first wedge plate 18 to move horizontally to the left. The movable plate 17 moves accordingly and compresses the second spring 39. When the socket 20 moves to a point where it is no longer in contact with the first limiting rod 14, the threaded plate 12 continues to move to the left to drive the strip plate 31 to move accordingly, and the first limiting rod 14 slides accordingly along the strip groove 19. The strip plate 31 continues to move to drive the teeth 32 to move to engage with the gear 33, and then moves to drive the gear 33 to rotate upward. The upward rotation of the gear 33 can drive the rotating shaft 6 and the second bed board 3 to rotate upward, thereby traction can be performed on the patient's lumbar vertebra in the up and down directions.

[0039] like Figure 8 and Fig. 9The right side of the third support plate 15 is fixedly connected with a blocking bar 30 for blocking the first movable plate 16. When the traction is completed and the second bed board 3 needs to be reset, the threaded plate 12 is controlled to move to the right. The movement of the threaded plate 12 can drive the strip plate 31 and the first limit rod 14 to move accordingly. The movement of the strip plate 31 can make the gear 33 and the second bed board 3 rotate downward. When the second bed board 3 rotates downward to a horizontal state, the tooth 32 is no longer in contact with the gear 33, and then the threaded plate 12 drives the first limit rod 14 to move accordingly. When the rod 14 moves to the same center as the socket 20, it continues to move and can pull the second movable plate 17, the first movable plate 16 and the first wedge plate 18 to move to the right. When the first movable plate 16 moves to contact with the baffle 30, the second wedge block 23 can no longer block the first wedge plate 18. At this time, under the action of the second spring 39, the first wedge plate 18 and the second movable plate 17 will move inward to reset, and the first limit rod 14 will be reinserted into the socket 20. At this time, the device is completely reset to its initial state.

[0040] like Figure 7-9The self-locking mechanism shown is connected to the second bed board 3 through a connecting mechanism, which includes two rectangular blocks 24, and the bottom surface of the rectangular block 24 is fixedly connected to the upper surface of the second movable plate 17 and the first wedge plate 18, and the two rectangular blocks 24 are fixedly connected to the second limiting rod 25 on the sides close to each other, and the bottom surface of the second bed board 3 is fixedly connected to the sixth support plate 26, and the left side of the sixth support plate 26 is fixedly connected to the first spring 28, and the other end of the first spring 28 is fixedly connected to the third movable plate 27, and the third movable plate 27 is provided with a limiting hole adapted to the second limiting rod 25, and the second limiting rod 25 is inserted into the limiting hole, and the sixth support plate 26 is fixedly connected to the first guide column 29 on the side close to the third movable plate 27, and the other end of the first guide column 29 slides through the third movable plate 27, and the first guide column 29 can support and guide the third movable plate 27, and when the second movable plate 17 and the first wedge plate 18 move, the rectangular block 24 and the second limiting rod 25 can be driven to move relative to each other. When the second movable plate 17 moves to a point where it is not in contact with the first limiting rod 14, the second limiting rod 25 will simultaneously move out from the inside of the limiting hole, and then the limiting of the third movable plate 27 can be released. After that, the rotation of the second bed board 3 can drive the sixth support plate 26 and the third movable plate 27 to rotate accordingly. By means of the first spring 28, after the second bed board 3 moves to the left to the initial state, when the first movable plate 16, the second movable plate 17 and the first wedge plate 18 continue to move to the left, the rectangular block 24 and the third movable plate 27 can be driven to move accordingly and the first spring 28 can be stretched. After the third movable plate 27 loses its limiting position, the first spring 28 can drive the third movable plate 27 to reset. When the second bed board 3 rotates downward to reset and the first movable plate 16 moves to contact the stop bar 30, the second limiting rod 25 will be concentric with the limiting hole, so that when the first wedge plate 18 and the second movable plate 17 move inward to reset, the second limiting rod 25 will be driven to be re-inserted into the inside of the limiting hole.

[0041] like Figure 3 and Figure 4 A driving mechanism for driving the threaded plate 12 to move horizontally is arranged above the bottom plate 1 as shown, and the driving mechanism includes a right-angle seat 8 and a second support plate 10, which are both fixedly connected to the upper surface of the bottom plate 1, and a motor 9 is installed on the right-angle seat 8. A threaded rod 11 is fixedly connected to the output end of the motor 9, and the end of the threaded rod 11 away from the motor 9 slides through the first support plate 4, the fifth support plate 22 and the first movable plate 16 in sequence and is rotatably connected to the inside of the second support plate 10, and the threaded plate 12 is threadedly connected to the outer surface of the threaded rod 11, and the motor 9 is started. When the motor 9 drives the threaded rod 11 to rotate forward, the threaded plate 12 can be driven to move horizontally to the right, and when the motor 9 drives the threaded rod 11 to rotate reversely, the threaded plate 12 can be driven to move horizontally to the left.

[0042] like Figure 5-7 The outer surface of the threaded plate 12 shown is fixedly connected to two symmetrical second fixing plates 35, and the sides of the two second fixing plates 35 that are away from each other are fixedly connected to support columns 36. The bottom surface of the second bed board 3 is fixedly connected to two symmetrical seventh support plates 37, and the interiors of the two seventh support plates 37 are provided with track grooves 38. The two support columns 36 are slidably connected to the interiors of the two track grooves 38 respectively. The track grooves 38 are composed of a horizontal groove and an inclined groove. When the second bed board 3 moves to the left to the initial state, the threaded plate 12 drives the strip plate 31 to continue to move horizontally to the left, and the support columns 36 will slide along the horizontal grooves. When the strip plate 31 drives the teeth 32 to move to mesh with the gear 33, and then drives the gear 33 to rotate, the support columns 36 will slide along the inclined grooves. Therefore, without affecting the rotation of the second bed board 3, the support columns 36 can always support the second bed board 3, thereby improving the stability of the second bed board 3 during use.

[0043] like Figure 2 A reset mechanism is provided above the bottom plate 1 shown, and the reset mechanism includes a first push plate 46 fixedly connected to the bottom surface of the second bed board 3 and an eighth support plate 47 fixedly connected to the upper surface of the bottom plate 1. A strong spring 48 is fixedly connected to the left side of the eighth support plate 47, and the other end of the strong spring 48 is fixedly connected to a second push plate 49 for blocking the first push plate 46. The end of the second push plate 49 away from the first push plate 46 is fixedly connected to a second guide column 50, and the other end of the second guide column 50 slides through the eighth support plate 47. The second guide column 50 is used to guide the movement of the second push plate 49. The second push plate 49 is a galvanized plate with a bending angle greater than 100 degrees, so that when the second bed board 3 drives the first push plate 46 to move horizontally to the right, the first push plate 46 can push the second push plate 49 It moves horizontally in the direction of the eighth support plate 47 and compresses the strong spring 48. When the threaded plate 12 moves to the left, under the action of the strong spring 48, the second push plate 49 can push the first push plate 46 and the second bed board 3 to move to the left to the initial state. When the second bed board 3 drives the first push plate 46 to rotate upward, the first push plate 46 can squeeze the second push plate 49 to move horizontally in the direction of the eighth support plate 47 and compress the strong spring 48. When the second bed board 3 drives the first push plate 46 to rotate downward, due to the folding edge setting of the second push plate 49, the first push plate 46 can also squeeze the second push plate 49 to move horizontally in the direction of the eighth support plate 47 and compress the strong spring 48, until the first push plate 46 rotates to the left side of the second push plate 49, and the strong spring 48 will drive the second push plate 49 to reset.

[0044] like Figure 1 A shielding frame 44 is fixedly connected to the upper surface of the bottom plate 1. By providing the shielding frame 44, the self-locking mechanism, the connecting mechanism and the driving mechanism can be shielded, thereby improving the aesthetics and safety of the device.

[0045] Working principle: When traction is performed on the patient's lumbar vertebra, first, the patient is made to lie flat on the first bed board 2 and the second bed board 3 and the patient is fixed by the fastening belt 42, and then the motor 9 is started to drive the motor 9 to rotate forwardly. The forward rotation of the threaded rod 11 can drive the threaded plate 12 to move to the right, and the movement of the threaded plate 12 can drive the first support plate 4, the second bed board 3 and the first push plate 46 to move accordingly and compress the strong spring 48. The second bed board 3 moves to pull the patient horizontally. After the traction is completed, the motor 9 drives the threaded rod 11 to rotate in the opposite direction. The reverse rotation of the threaded rod 11 can drive the threaded plate 12 to move to the left. At the same time, the strong spring 48 will push the second push plate 49, the first push plate 46 and the second bed board 3 to move to the left. When the first support plate 4 moves to contact with the baffle 34, it means that the second bed board 3 moves to the left to the initial state. When it is necessary to pull the patient's lumbar vertebra up and down, the threaded rod 11 is continued to be driven to rotate in the opposite direction. Due to the first support plate 4, the third support plate 15 and the second wedge block 2 3 is in a relatively fixed state. When the threaded plate 12 drives the second movable plate 17, the first movable plate 16, the first wedge plate 18, the rectangular block 24 and the third movable plate 27 to move horizontally to the left, the second wedge block 23 will squeeze the first wedge plate 18 to slide outward. The movement of the first wedge plate 18 can drive the second movable plate 17, the rectangular block 24 and the second limiting rod 25 to move accordingly and compress the second spring 39. When the second movable plate 17 moves to no longer contact with the first limiting rod 14, the second limiting rod 25 is completely moved out of the limiting hole. At this time, the threaded plate 12 continues to move to the left to drive the strip plate 31 to move accordingly, and the first limiting rod 14 slides accordingly along the strip groove 19. The strip plate 31 continues to move to drive the teeth 32 to move to mesh with the gear 33. Then the movement can drive the gear 33 to rotate upward. The gear 33 rotates upward to drive the rotating shaft 6, the third movable plate 27 and the second bed board 3 to rotate upward. The second bed board 3 rotates upward to pull the patient's lumbar vertebra in the up and down directions.

[0046] After traction is completed, when it is necessary to control the second bed board 3 to reset, the motor 9 drives the threaded rod 11 to rotate forward, and the threaded plate 12 moves to the right to drive the strip plate 31 and the first limiting rod 14 to move accordingly. The movement of the strip plate 31 can make the gear 33 and the second bed board 3 rotate downward. When the second bed board 3 rotates downward to a horizontal state, the tooth 32 no longer contacts the gear 33. Then the threaded plate 12 drives the first limiting rod 14 to move to the same center as the plug hole 20, and continues to move to pull the second movable plate 17, the first movable plate 16, The first wedge plate 18, the rectangular block 24 and the second limiting rod 25 move to the right. When the first movable plate 16 moves to contact with the blocking bar 30, the second wedge block 23 can no longer block the first wedge plate 18. At this time, under the action of the second spring 39, the first wedge plate 18, the second movable plate 17, the rectangular block 24 and the second limiting rod 25 will move inward to reset. The first limiting rod 14 will be reinserted into the inside of the socket 20, and the second limiting rod 25 will be reinserted into the inside of the limiting hole. At this time, the device is completely reset to the initial state.
