[0002] Working at a desk for long periods of time or performing heavy physical work can easily cause lumbar strain and even certain distortion and deformation of the lumbar spine. To adjust the distorted lumbar spine back to its normal physiological curvature, a lumbar traction bed is often used for rehabilitation therapy. For example, Chinese patent application (CN106344243A) discloses a lumbar traction bed in its specification, comprising a bed body, the bed body being provided with a bidirectional traction mechanism that extends toward both ends of the bed body, the bed body having front and rear support frames extending upward at a certain height at the front and rear ends, respectively. The bidirectional traction mechanism comprises a first traction belt for securing the patient's chest and extending toward the front end of the bed body, and a second traction belt for securing the patient's waist and extending toward the rear end of the bed body, and further comprising a drive and tightening device for winding and tightening the two traction belts. The first and second traction belts pass through the front and rear support frames, respectively, and are connected to the drive and tightening device.

[0052] In order to provide comfort for the user lying on the support bed 1, a mattress 7 is additionally installed, and the mattress 7 is laid on the support bed 1.

[0053] In some alternative embodiments, a neck traction member is additionally installed. Such as Figure 2 、 3 As shown, the neck traction member is installed at one end of the support bed 1.

[0054] Such as Figure 2 As shown, the neck traction member includes a support vertical rod 21, an adjustment bolt 23, a transverse rod 25 and a neck traction belt 28. An adjustment slot 22 is opened in the support vertical rod 21 along the height direction; the adjustment bolt 23 passes through the adjustment slot 22 and clamps and fixes the support vertical rod 21. The transverse rod 25 is installed at the top end of the support vertical rod 21, and hooks 26 are installed at both ends of the transverse rod 25; both ends of the neck traction belt 28 are respectively connected to the corresponding hooks 26.

[0055] The neck traction member is installed at the end of the support bed 1, and the height of the support vertical rod relative to the top surface of the support bed can be adjusted.

[0056] A connection structure between the support vertical rod and the support bed: a screw hole 24 is opened at the end of the support bed. The adjustment bolt 23 passes through the adjustment slot 22 and is threadedly connected to the screw hole 24. When the adjustment bolt 23 is tightened, the adjustment bolt squeezes the support vertical rod and fixes it on the support bed. When the height of the support vertical rod needs to be adjusted, loosen the adjustment bolt, and the support vertical rod can be vertically moved to adjust the height of the support vertical rod.

[0057] The adjustment bolt 23 can be a knob screw, and one structure of the knob screw can be a plum blossom hand-tightening screw, a cross knob screw, etc.

[0058] Further in this embodiment, in order to facilitate the connection between the neck traction belt 28 and the hook, a hanging ring 27 is additionally installed. Hanging rings 27 are provided at both ends of the neck traction belt 28, and the neck traction belt is suspended on the hook 26 through the hanging rings 27. The quick connection between the neck traction belt and the hanging ring can be realized.

[0059] Further in this embodiment, in order to enhance the support for the support vertical rod 21, a reinforcing plate 33 is additionally installed. The reinforcing plate 33 is located above the screw hole 24 and is fixedly installed on the end face of the support bed. The support vertical rod 21 can be in movable contact with the reinforcing plate 23. When the support vertical rod 21 is subjected to a pulling force, the reinforcing plate 23 can support the support vertical rod, and the stability of the support vertical rod can be further improved.

[0060] In some alternative embodiments, a structure for adjusting the length of the support bed is provided. The support bed 1 includes a first splicing bed 111, an adjusting screw 31, and a second splicing bed 112. The first splicing bed 111 is provided with a first support rod 118, and a first splicing leg 115 is installed at the bottom. A first rod 116 is installed on the first splicing leg 115, and an adjusting support 30 is installed on the first rod 116; the second splicing bed 112 is provided with a second support rod 117, and a second splicing leg 113 is installed at the bottom. The second support rod 117 is movably inserted into the first support rod 118, and a support seat 29 is installed on the second splicing leg 113; the adjusting screw 31 is in threaded connection with the adjusting support 30 and is then rotatably connected to the support seat 29.

[0061] The adjusting screw 31 and the support seat 29 can be connected by a bearing. The bearing can support the rotation of the adjusting screw relative to the support seat.

[0062] In order to facilitate the operation of the adjusting screw 31, a handle plate 32 is additionally installed, and the handle plate 32 is installed on the adjusting screw 31. By rotating the handle plate, the adjusting screw can be driven to rotate.

[0063] A method for adjusting the length of the support bed:

[0064] When the adjusting screw 31 is rotated clockwise, the adjusting screw 31 extends outward relative to the adjusting support 30. The adjusting screw 31 pushes the second splicing bed 112 to move, and the second splicing bed 112 drives the second support rod 117 to extend outward from the first support rod 118, realizing an increase in the length of the support bed.

[0065] When the adjusting screw 31 is rotated counterclockwise, the adjusting screw 31 contracts inward relative to the adjusting support 30. The adjusting screw 31 drives the second splicing bed 112 to move, and the second splicing bed 112 drives the second support rod 117 to extend inward toward the first support rod 118, realizing a decrease in the length of the support bed.

[0066] In some alternative embodiments, a structure of the traction bracket is provided. The traction bracket 6 includes a cross bar 61, and two parallel and spaced vertical bars 62 are installed at intervals at the ends of the cross bar 61. One end of the vertical bar 62 extends upward and protrudes from the top surface of the support bed 1, and the other end extends downward and is connected to one end of a second reinforcing bar 64. The other end of the second reinforcing bar 64 is connected to the bottom plate 66, and the bottom plate 66 is connected to the support bed 1 by a plurality of fourth bolts 65; and the vertical bar 62 is fixedly connected to the support bed 1 by being clamped with a third bolt 63.

[0067] The height by which the vertical bar 62 extends upward relative to the top surface of the support bed may be 15 - 30 cm. Commonly selectable heights may be 15, 20, 25, or 30 cm. It can be understood that the height of the vertical bar can be adjusted relative to the support bed.

[0068] It should be noted that when a mattress is installed on the support bed, the height by which the vertical bar extends from the top surface of the support bed is added to the thickness of the mattress. When the thickness of a mattress is 10 cm, the height by which the vertical bar extends from the top surface of the support bed is added with 10 cm, and the actual height by which the vertical bar extends upward can be obtained.

[0069] To facilitate placing items at the bottom of the support bed, a storage rack 5 is additionally installed. The storage rack 5 is installed at the bottom of the support bed 1 and can be used to support and place items.

[0070] To enhance the top load-bearing capacity of the support bed, a first reinforcing bar 2 is additionally installed, and a first reinforcing bar 2 is installed on the side surfaces at both ends of the head of the bed respectively.

[0071] As Figure 1 shown, one end of the first reinforcing bar 2 is fixedly connected to the leg of the support bed by a first bolt 3, and the other end is fixedly connected to the side surface of the support bed by a second bolt 4.

[0072] In some alternative embodiments, a structure of the tractor is provided. As Figures 4 - 8 shown, the tractor 20 includes a traction force measuring member, a cable tightener, and a clamping and fixing member. Both ends of the cable tightener are respectively hinge-connected to the traction force measuring member and the clamping and fixing member.

[0073] The clamping and fixing member is used to clamp the traction bracket so that the entire tractor is installed on the traction bracket.

[0074] The traction force measuring member displays the traction force value during traction.

[0075] The cable tightener is used to pull and loosen the traction rope. When traction force needs to be provided, the cable tightener tightly winds the traction rope, the traction rope is in a taut state, and the traction rope provides an outward traction force. When the cable tightener loosens the traction rope, the outward traction force is released, and the traction rope can be in a relaxed state.

[0076] The cable tightener includes two support bodies 212 arranged in parallel at intervals, a winding drum 226, an anti-reverse member 218, a second pawl 227, a first torsion spring 215 and an operating rod 229. The winding drum 226 is placed between the two support bodies 212. One ends of the two support bodies 212 are connected by a first limiting roller 211, and the other ends are connected by a second limiting roller 219. The operating rod 229 is rotatably installed on the support body 212. The winding drum 226 is provided with a ratchet wheel 2262. The second pawl 227 is installed on the operating rod 229 and connected to a third torsion spring 228, and is in meshing transmission connection with the ratchet wheel 2262. The anti-reverse member 218 is provided with a first pawl 2181, which is rotatably connected to the support body 212 and is elastically extruded by a second torsion spring 225. The first pawl 2181 remains in meshing connection with the ratchet wheel 2262 to prevent the ratchet wheel 2262 from reversing. Among them, the two support bodies 212, the winding drum 226 and the operating rod 229 are connected by a first shaft 213. The first torsion spring 215 is installed on the first shaft 213, and its two torsion rods are elastically connected to the two ends of a support body 212 respectively.

[0077] The connection structure of the two torsion rods of the first torsion spring 215 and the support body: The first torsion rod 2151 is elastically connected to one end of the support body, and the other end of the support body is elastically connected to the second torsion rod 2152.

[0078] The third torsion spring 228 is installed on the operating rod 229 through a third shaft 230. The fifth torsion rod 2281 of the third torsion spring 228 is elastically connected to the operating rod 229, and the sixth torsion rod 2282 is elastically connected to the second pawl 227. The sixth torsion rod presses the second pawl 227 on the top of the ratchet wheel 2262. When the operating rod 229 swings, the operating rod 229 drives the second pawl 227 to move and remain in meshing transmission connection with the ratchet wheel 2262, so that the second pawl can push the ratchet wheel to rotate.

[0079] It should be noted that when the operating rod resets, the second pawl is not located in the tooth groove of the ratchet wheel, but on the top surface of the ratchet wheel. Therefore, the second pawl does not block the reverse rotation of the ratchet wheel.

[0080] As Figure 8 shown, a structure of the support body includes a first extension end 2121, a second extension end 2123 and a main body 2122. The main body 2122 can be in a disc structure. The diameters of the first extension end 2121 and the second extension end 2123 are both smaller than the diameter of the main body 2122. The first extension end 2121 and the second extension end 2123 extend outward from the main body 2122 and show a gradually narrowing opening. A visual opening 2120 is opened at the connection between the first extension end 2121 and the main body 2122. The visual opening 2120 can facilitate viewing the working conditions of the components inside the two support bodies.

[0081] As Figure 6As shown in the figure, a structure of a traction force measuring member is given. The traction force measuring member includes a bracket 220, a pulling spring 221 and a traction plate 222. Sliding grooves 2201 are provided on both sides of the bracket 220, and a sealing plate 2202 with a through groove 2203 is provided at one end, which is rotatably connected to the tightener; on both sides of one end of the traction plate 222, guide sliders 2221 are provided and are connected to one end of the pulling spring 221. The other end passes through the through groove 2203, and the guide sliders 2221 are inserted into the corresponding sliding grooves 2201 and extend outward along the side surface of the corresponding bracket 220; the other end of the pulling spring 221 is connected to the tightener; among them, the traction plate 222 is provided with a force measuring scale 2222.

[0082] The length that the guide slider 221 extends outward relative to the bracket 220 can be 2 - 3 cm. The two guide sliders can support the traction plate to move on the bracket without disengaging from the guide chute.

[0083] The force measuring scale 2222 can facilitate the user to quickly know the traction force during traction. The range of the force measuring scale 2222 can be 10 - 60 kg. The markable scales are 10 kg, 20 kg, 30 kg, 40 kg, 50 kg, 60 kg. The range of the traction force that can be selected during traction can be 20 - 30 kg. It can be 20, 25 or 30 kg, etc. Of course, it is not limited to this, and the appropriate traction force can be selected according to the lumbar curvature.

[0084] It should be noted that a way to read the force measuring scale on the traction plate: When the traction plate 222 moves out of the bracket 220 and stops moving, the sealing plate 2202 is perpendicular to the traction plate. At this time, the scale on the sealing plate corresponding to the traction plate is the traction force value.

[0085] Hanging holes 2223 are provided on the traction plate 222, which can facilitate the connection with the traction rope. To make it more convenient to connect the traction plate with the traction rope, a first pull ring 223 is additionally installed. The first pull ring 223 can facilitate the bundling connection between the traction plate and the traction rope.

[0086] As Figure 4 、 5 As shown in the figure, a structure of the operating rod 229 includes the splicing of two swing rods, and each swing rod is connected to the support body through a first shaft 213. The swing rod can swing relative to the support body 212 by means of the first shaft 213.

[0087] The swing rod includes a first rod section 2291, a second rod section 2292 and a third rod section 2293. The first rod section 2291 and the third rod section 2293 are connected by the second rod section 2292, and the second rod section 2292 is inclined.

[0088] When the two third rod sections 2293 are spliced, the two third rod sections can be riveted through rivets to realize the fixed connection of the two third rod sections.

[0089] As Figure 4 , 5 shown, the clamping and fixing member includes a clamping body 201, an adjusting screw 207, a second support plate 206, a first support plate 204, a fifth bolt 205, a second clamping plate 209 and a first clamping plate 208. One end of the clamping body 201 is provided with a first leg 202 bent downward, and the other end is provided with an inclined second leg 210; the first support plate 204 is installed on the first leg 202, and the second support plate 206 and the first support plate 204 are fixedly connected by a fifth bolt 205. After the adjusting screw 207 is screwed with the second support plate 206, it is rotatably connected to the first clamping plate 208; the second clamping plate 209 is installed on the second leg 210, wherein the clamping body 201 is rotatably connected to the tightener.

[0090] The second clamping plate 209 and the first clamping plate 208 can be arc-shaped plates. One kind of rotational connection between the adjusting screw 207 and the first clamping plate 208 can be that the adjusting screw and the first clamping plate can be connected by a bearing. The adjusting screw can rotate relative to the first clamping plate by means of the bearing.

[0091] In order to facilitate the operation of the adjusting screw 207, a butterfly handle 203 is installed on the adjusting screw 207. By turning the butterfly handle 203, the adjusting screw 207 can be driven to rotate.

[0092] The working mode of the lumbar traction of the present utility model:

[0093] The user lies prone on the support bed, with the head naturally drooping on the head breathing hole. Then, the first lumbar traction belt is fixed to the user's chest through the second adjusting strap 11 and abuts against the user's armpit. Then, the first adjusting strap 10 on the first lumbar traction belt is tied to the traction bracket. The second lumbar traction belt is tied and fixed to the user's waist through the second adjusting strap 11 thereon. Then, two traction devices 20 are used to apply traction force to the user. While providing the traction force, the traction device displays the traction force value, and the traction force value provided by the traction device can be quickly obtained through the traction plate 222 on the traction device.

[0094] The traction device 20 tightly winds the traction rope to realize that the traction rope provides traction force outward. During the working process of the traction device, the fourth torsion rod 2252 of the second torsion spring 225 presses the first pawl 2181 to keep meshing with the ratchet wheel 2262. The anti-reversal member 218 can block the reverse rotation of the ratchet wheel 2262, which is beneficial for the operating rod 229 to drive the second pawl 227 to push the ratchet wheel 2262 to rotate forward. When the ratchet wheel 2262 rotates, it can drive the winding drum 226 to rotate, realizing that the traction rope is tightly wound on the winding drum. When the operating rod is stopped, the anti-reversal member 218 blocks the reverse rotation of the ratchet wheel 2262.

[0095] Pull the pull ring 223, the pull ring 223 drives the pull rope 217, the pull rope 217 pulls the anti-reversal member 218 to swing, so that the first pawl 2181 on the anti-reversal member 218 disengages from the ratchet wheel 2262, releasing the block on the reverse rotation of the ratchet wheel. When pulling, the pulling spring 221 generates elastic deformation and has elastic deformation potential energy. The pulling spring pulls the traction plate to move backward and reset, and the traction plate pulls the traction rope 17 to loosen outward from the winding cylinder 226, releasing the pulling effect.

[0096] When the utility model is used for auxiliary lumbar traction, the prone position is adopted. When lying prone, the lumbar spine is upward, which is convenient for observing the changes of the user's lumbar spine and is conducive to the traction device to cooperate with the angle adjustment, so as to adjust the lumbar curvature to restore the normal curvature. During the actual use process, the traction force applied to the user is usually 20-30 kg and is adjusted according to different situations. The number of times of traction is usually changed after three to seven times; through the adjustment of the device of the utility model, the uncomfortable situation will be gradually alleviated or eliminated, and the curvature of the lumbar spine will slowly return to the normal state.

[0097] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the utility model.
