Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment technology, specifically to a spinal manipulation device with variable distance and torque. Background Technology

[0002] In modern society, the prevalence of spinal diseases is rising due to prolonged desk work and lack of effective exercise. Chiropractic manipulation, as a relatively gentle and non-invasive treatment method, is gaining popularity. Chiropractic manipulation can improve muscle tension and relieve muscle tension and stiffness caused by prolonged poor posture or overuse. It can also promote blood circulation by adjusting the spine, improving the flow of blood and lymph, thereby promoting nutrient supply and waste removal from various parts of the body. Furthermore, it can relieve pain caused by spinal problems, such as neck pain, back pain, or sciatica, reducing pain and improving quality of life. Therefore, by adjusting the spine and surrounding soft tissues, chiropractic manipulation helps restore the body's natural balance and function.

[0003] While existing chiropractic pressure devices can perform chiropractic pressure operations and adjust the pressure intensity, they struggle to adjust the pressure distance, failing to meet the optimal pressure distance required by different patients' spines. This affects the effectiveness of the chiropractic pressure. A short pressure distance cannot achieve the best effect, while a long pressure distance can cause damage due to excessive adjustment of the spinal joints. For example, Chinese invention patent application CN117224349A discloses an intelligent chiropractic pressure device that has the function of adjusting the pressure intensity, but its supporting main axis... The spacing between the arc-shaped indentations on the surface is fixed, thus the distance of the spinal manipulation and pressing is fixed, which has the drawback that the distance of the spinal manipulation and pressing is difficult to adjust. In addition, the spinal manipulation and pressing intensity is controlled by controlling the deformation of the springs. The springs located on both sides of the main support shaft apply force to a single main support shaft. The displacement distance of the two damping adjustment rods is prone to be inconsistent, resulting in different elastic forces exerted by the two oppositely set springs on the main support shaft. This causes the main support shaft to be prone to unstable force, resulting in unstable lifting and lowering of the bed board driven by the main support shaft, which leads to deviations in the position of the spinal manipulation and pressing massage on the patient. Summary of the Invention

[0004] To address the problems of existing spinal manipulation devices that can only adjust the pressure intensity while the manipulation distance is difficult to adjust, and the instability of the bed board during lifting and lowering, this invention provides a spinal manipulation device with variable distance and torque. This device has the function of adjusting both the pressure intensity and distance of the spinal manipulation, which facilitates the adjustment of the manipulation distance and can meet the optimal manipulation distance required by different patients' spines. At the same time, by using locking components to act on the limiting seats, the stability of the bed board during lifting and lowering is ensured.

[0005] To achieve the above objectives, the technical solution of the present invention is: a variable distance and torque ridge straightening and pressing device, comprising a base plate and pressing mechanism, lifting mechanism, rotating shaft mechanism and pushing and pulling mechanism disposed on the base plate.

[0006] The top of the base plate is provided with a limiting seat, which includes a vertical moving block, a limiting block and a wedge block. The wedge block is inserted between the vertical moving block and the limiting block. A push-pull mechanism is connected to the wedge block and is used to drive the wedge block to make horizontal movement to adjust the ridge pressing distance of the pressing mechanism. Through the action of the push-pull mechanism, the wedge block can be driven to move between the vertical moving block and the limiting block, and the distance between the vertical moving block and the limiting block can be adjusted to achieve the effect of adjusting the ridge pressing distance.

[0007] The lifting mechanism drives the pressing mechanism to move upward. The pressing mechanism includes a movable seat and locking components symmetrically arranged inside the movable seat. The two locking components respectively press against two oppositely installed limiting seats. The rotating shaft mechanism is connected to two locking blocks that cooperate with the locking components. The locking components press against the limiting seats to generate a locking force. The movable seat descends to overcome the locking force of the locking components, thus realizing the spinal pressing massage action on the patient. The two locking components use a double-sided pressing and movable seat movement method, which can make the force on the movable seat stable during the movement. The rotating shaft mechanism can drive the two locking blocks to move in opposite directions, changing the pressing force of the locking blocks on the locking components, which can change the locking force generated by the locking components pressing against the limiting seats, thereby adjusting the intensity of the spinal pressing pressure.

[0008] The locking assembly is equipped with a first detection module, and the lifting mechanism is equipped with a second detection module. The first and second detection modules are respectively connected to a control unit, which is used to calculate the intensity value of the spinal manipulation torque and control the operation of the lifting mechanism. By combining the locking force of the locking assembly with the detection of the first detection module, and processing the data through the control unit, the intensity of the manipulation torque is calculated, ensuring that the spinal manipulation torque is matched to the condition of different patients.

[0009] Furthermore, the limiting seat also includes an L-shaped plate, and the top of the vertical moving block is provided with a fixed shaft that passes through the horizontal part of the L-shaped plate. A compression spring is sleeved on the fixed shaft. The fixed shaft guides the lifting and lowering movement of the vertical moving block, and the compression spring acts on the vertical moving block to make the bottom of the vertical moving block tightly fit against the wedge block. This prevents the vertical moving block from becoming unstable when the moving seat drives the locking assembly to squeeze the limiting seat, thereby avoiding abnormal changes in the locking force generated by the locking assembly squeezing the limiting seat.

[0010] Furthermore, the vertical moving block and the limiting block have upper and lower arc grooves respectively on their inner sides, and the wedge block has two symmetrical arc grooves on its inner side. The two arc grooves, together with the upper and lower arc grooves, form an upper locking groove and a lower locking groove, respectively. The wedge block moves horizontally to adjust the distance between the vertical moving block and the limiting block, thereby adjusting the lifting height of the moving seat and adjusting the ridge pressing distance.

[0011] Furthermore, the locking assembly includes a spring and a locking ball arranged sequentially from the inside to the outside. The first detection module includes a pressure sensor, which is disposed between the spring and the locking ball and is fixed to both the spring and the locking ball. The locking ball corresponds to the upper or lower locking groove on the same side. The output end of the pressure sensor is connected to the input end of the control unit.

[0012] A pressure sensor is used to detect the locking force (pressure on the locking ball) of the locking assembly in real time and transmit it to the control unit to monitor the treatment process and provide calculation parameters for the control unit.

[0013] Furthermore, the movable seat is connected to a ball bearing at the bottom and has a supporting steel plate at the top. A mattress is placed on top of the supporting steel plate. Multiple guide components connected to the base plate are arranged at the bottom of the supporting steel plate. The guide components are used to guide the lifting and lowering movement of the mattress. The patient can lie on the mattress, which improves the patient's comfort when performing spinal manipulation massage.

[0014] Furthermore, the rotating shaft mechanism includes a connecting seat, a handwheel shaft, a driven shaft, a driven gear, and a driving gear; The number of connecting seats is two, and a handwheel shaft is provided between the two connecting seats. The handwheel shaft is rotatably connected to the connecting seats. Two driving gears are symmetrically provided on the handwheel shaft. The driving gears mesh with driven gears. The driven gears are fixed to the driven shafts. The two driven shafts are rotatably connected to the connecting seats respectively. The upper end of the connecting seat is fixed to the supporting steel plate. Rotating the handwheel shaft causes the two driven shafts to rotate simultaneously with the handwheel shaft through the engagement of the driving gear and the driven gear.

[0015] Furthermore, locking blocks are slidably mounted on the two driven shafts, and the two locking blocks move in opposite directions or relative to each other. One end of each locking block extends into the interior of the movable seat and presses against the opposite ends of the two springs. A slide rail assembly is provided on the top of each locking block to guide its movement. When the driven shafts rotate, they drive the locking blocks to move. By changing the position of the locking blocks, the deformation of the springs can be controlled, and the locking force generated by the locking ball pressing against the limiting seat can be adjusted, thereby adjusting the overall pressure.

[0016] Furthermore, the lifting mechanism includes a power component, a side plate, a position sensing plate, and a conical cam. The conical cam is connected to the power component, which drives the conical cam to rotate to lift the moving seat. In addition, the second detection module detects the rotation angle of the conical cam of the lifting mechanism to ensure that the power component stops working after the conical cam has rotated one revolution.

[0017] The tapered cam has a "~" shaped structure. The arc surface of the tapered cam contacts the ball bearing and is used to lift the ball bearing. The arc surface of the tapered cam is the path of the ball bearing's movement. The side plate and the bottom plate are fixed. The power assembly drives the position sensing plate to rotate. The position sensing plate and the side plate are parallel. The second detection module includes a magnet and a Hall sensor. The magnet is fixedly installed on the side of the position sensing plate facing the side plate. The Hall sensor is fixedly installed on the side of the side plate facing the position sensing plate. The output terminal of the Hall sensor is connected to the input terminal of the control unit. The control unit is electrically connected to the power assembly.

[0018] By utilizing the arc surface of the tapered cam to lift the ball bearing, the wear of the tapered cam can be prevented from occurring due to prolonged use.

[0019] Based on the operating principle of Hall sensors, whenever a magnet passes the Hall sensor, the Hall sensor outputs an electrical signal to the control unit. This signal serves as a stop signal, enabling power-off control of the power components. Because the position sensing plate and the conical cam rotate coaxially, the rotation angle of the conical cam can be represented by the rotation angle of the position sensing plate. When the position sensing plate rotates one full revolution (360°), the magnet passes the position of the Hall sensor once, and the Hall sensor outputs a signal to the control unit to cut off power to the power components.

[0020] Furthermore, the push-pull mechanism includes a push-pull assembly and a sliding block. The push-pull assembly includes a fixed block and a trapezoidal lead screw. The fixed block is fixed to the top of the base plate, and one end of the trapezoidal lead screw is rotatably connected to the fixed block. The sliding block is driven onto the trapezoidal lead screw, and both ends of the sliding block are connected to two wedge blocks respectively. By rotating the trapezoidal lead screw, the sliding block can be driven to move horizontally on the base plate. The sliding block drives the wedge blocks to move, thereby adjusting the distance between the vertical moving block and the limiting block, achieving the effect of adjusting the ridge pressing distance.

[0021] A conical cam moving mechanism is fixedly provided at the lower end of the sliding block. The conical cam moving mechanism includes a fixed plate and a protective frame. The conical cam moving mechanism is used to drive the conical cam to move with the sliding block. The longitudinal section of the cone cam is a cone shape with one end larger than the other, with the larger end close to the fixed plate and the smaller end far away from the fixed plate.

[0022] When the ridge pressing distance changes during operation, the distance between the ball bearing and the tapered cam will change. To address this, the longitudinal section of the tapered cam is set to be tapered with one end larger than the other. The tapered cam moves with the sliding block through the tapered cam moving mechanism, changing the contact position between the tapered cam and the ball bearing, so that the tapered cam can still contact the ball bearing after the ball bearing position changes.

[0023] Furthermore, the push-pull mechanism also includes rotating components. Two rotating components are symmetrically mounted on the top of the base plate. Each rotating component includes a mounting block, a handle rod, a driving bevel gear, and a first handle. The handle rod is rotatably connected to the mounting block, and its two ends are respectively connected to the driving bevel gear and the first handle. The driving bevel gear meshes with the driven bevel gear, which is fixedly mounted on the trapezoidal lead screw. The first handle allows the handle rod to be rotated, causing the driving bevel gear to rotate and drive the driven bevel gear to rotate, thereby causing the driven bevel gear to drive the trapezoidal lead screw to rotate.

[0024] The beneficial effects of the present invention through the above technical solution are as follows: 1. When performing spinal manipulation massage, the movable seat moves up and down, and its internal locking components press against two opposing limiting seats. Compared to existing technologies where two locking components press against a single moving support shaft, the movable seat is not compressed by locking balls. In this invention, the locking components press against two limiting seats located on both sides and with their bottoms fixed, ensuring more stable force distribution during the movement of the movable seat and greater stability when the mattress is raised and lowered. This avoids shaking during mattress raising and lowering, improves the patient's comfort during spinal manipulation massage, and prevents deviations in the position of the spinal manipulation massage, thus enhancing the effectiveness of the massage.

[0025] 2. This invention uses a push-pull mechanism to drive a wedge block to move horizontally. The wedge block moves between a vertical moving block and a limiting block, thereby adjusting the distance between the vertical moving block and the limiting block. This achieves the effect of adjusting the spinal manipulation pressure distance, meeting the optimal pressure distance required by different patients' spines, improving the applicability range, and ensuring that the pressure distance achieves the best spinal manipulation pressure massage effect for patients. This avoids damage caused by excessive adjustment of the patient's spinal joints and improves the effect of spinal manipulation pressure massage for patients.

[0026] 3. This invention can change the pressure intensity of the spinal manipulation by adjusting the locking force of the locking assembly, ensuring that the pressure intensity matches the condition of different patients. A rotating shaft mechanism is provided; by rotating the handwheel shaft, the locking blocks that move in opposite directions or relative to each other are moved, thereby adjusting the spring tension. When the spring tension changes, the locking force of the locking assembly is adjusted, thus regulating the pressure intensity. Additionally, a pressure sensor is provided to monitor the locking force in real time. The pressure sensor transmits the detected parameters to the control unit, which calculates the pressure torque intensity value for medical staff to reference, facilitating timely adjustments to the pressure intensity.

[0027] 4. The spinal manipulation and pressure massage involves the pressure mechanism rising to lift the patient's spine, followed by medical staff pressing down to lower the pressure mechanism back to its original position. This invention incorporates a Hall sensor and a magnet to detect the rotation angle of the conical cam. The control unit controls the power assembly to rotate the conical cam 360° to its original position. During this process, the ball bearing is lifted, and the moving seat rises. Because the locking ball of the locking assembly is limited within the upper arc groove, the moving seat keeps the ball bearing suspended, requiring external pressure to return it to its original position. This invention ensures that the pressure mechanism can complete the spinal manipulation and pressure massage action. Simultaneously, the suspended position prevents the conical cam from contacting the ball bearing, thus protecting the power assembly from reverse rotation due to external force during pressure.

[0028] 5. This invention uses a conical cam to rotate and lift a ball bearing, thereby raising the movable seat. The conical cam's arc surface serves as the movement path of the ball bearing, cooperating with it to prevent wear and tear on the conical cam over time and ensure the stability of the movable seat during movement. This, in turn, ensures the stability of the mattress during movement and improves the comfort of patients when receiving spinal manipulation massage. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: In the description of this invention, it should be understood that the terms "left," "right," "up," "down," "horizontal," and "vertical," etc., indicate the orientation or positional relationship based on the appendix. Figure 1The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0033] like Figures 1 to 16 As shown, a variable distance and torque ridge straightening and pressing device includes a base plate 1 and pressing mechanism 3, lifting mechanism 4, rotating shaft mechanism 6 and pushing and pulling mechanism 5 disposed on the base plate 1. The bottom plate 1 is provided with a limiting seat 2 on its top. The limiting seat 2 includes a vertical moving block 202, a limiting block 203 and a wedge block 204. The wedge block 204 is inserted between the vertical moving block 202 and the limiting block 203. The push-pull mechanism 5 is connected to the wedge block 204 and is used to drive the wedge block 204 to move horizontally and adjust the distance between the vertical moving block 202 and the limiting block 203. The lifting mechanism 4 drives the pressing mechanism 3 to move upward. The pressing mechanism 3 includes a movable seat 301 and locking components 302 symmetrically arranged inside the movable seat 301. The two locking components 302 respectively press the two oppositely installed limiting seats 2. The rotating shaft mechanism 6 is connected to two locking blocks that cooperate with the locking components 302. The locking assembly 302 is provided with a first detection module, and the lifting mechanism 4 is provided with a second detection module. The first detection module and the second detection module are respectively connected to the control unit. The control unit is used to calculate the strength value of the pressure torque and control the lifting mechanism 4 to work.

[0034] Two limiting seats 2 are symmetrically installed on the top of the base plate 1. The two limiting seats 2 are located at both ends of the pressing mechanism 3. Each limiting seat 2 includes a vertical moving block 202, a limiting block 203, and a wedge block 204. The vertical moving block 202 is located above the limiting block 203 and corresponds vertically to the limiting block 203. The wedge block 204 is inserted between the vertical moving block 202 and the limiting block 203. The push-pull mechanism 5 is connected to the wedge block 204. The lifting mechanism 4 drives the pressing mechanism 3 to move upward. The pressing mechanism 3 includes a moving seat 301 and locking components 302 symmetrically installed inside the moving seat 301. Two locking components 302 are pressed against two opposing limiting seats 2 by the rotating shaft mechanism 6. The rotating shaft mechanism 6 presses the locking components 302 to restrict their position. During the lifting and lowering of the movable seat 301, the locking components 302 can move inside the movable seat 301. The bottom of the movable seat 301 is connected to a ball bearing 303 and the top is provided with a support steel plate 304. The top of the support steel plate 304 is provided with a mattress 305. The bottom of the support steel plate 304 is provided with a plurality of guide components connected to the base plate 1. The guide components are used to guide the lifting and lowering movement of the mattress 305.

[0035] The support steel plate 304 is bolted to the movable seat 301 and the mattress 305. There are four guide components at the bottom of the support steel plate 304, which are respectively installed at the corners of the support steel plate 304. The guide components include a guide shaft 3041 and a buffer column 3042 fitted on the guide shaft 3041. The upper end of the guide shaft 3041 is fixed to the support steel plate 304, and the lower end passes through the base plate 1. The base plate 1 is equipped with a linear bearing 101 that cooperates with the guide shaft 3041, and there are also four linear bearings 101 on the base plate 1. The guide shaft 3041, through cooperation with the linear bearing 101, guides the movement of the movable seat 301, the support steel plate 304, and the mattress 305. The buffer column 3042 buffers the descending support steel plate 304 and is made of polyurethane material.

[0036] The limiting seat 2 cooperates with the locking component 302 of the pressing mechanism 3 to compress the limiting seat 2 and generate the required locking force. The wedge block 204 has a triangular front end and a square rear end, which is to facilitate the insertion of the wedge block 204 between the vertical moving block 202 and the limiting block 203 to adjust the distance between the vertical moving block 202 and the limiting block 203. The bottom of the vertical moving block 202 and the top of the limiting block 203 are both inclined surfaces and match the wedge block 204. The bottom surface of the limiting block 203 is fixedly connected to the base plate 1. The wedge block 204 moves between the vertical moving block 202 and the limiting block 203. The push-pull mechanism 5 drives the wedge block 204 to move horizontally to adjust the distance between the vertical moving block 202 and the limiting block 203, thereby adjusting the pressing distance of the ridge.

[0037] The top of the limiting block 203 is provided with an inclined sliding groove 2032, and the bottom of the wedge block 204 is provided with a protrusion 2042 that matches the inclined sliding groove 2032. The protrusion 2042 and the inclined sliding groove 2032 slide together. When the position of the wedge block 204 is adjusted, the protrusion 2042 slides in the inclined sliding groove 2032 during the process of pushing and pulling the wedge block 204. The movement of the wedge block 204 is guided by the cooperation between the protrusion 2042 and the inclined sliding groove 2032.

[0038] The push-pull mechanism 5 includes a push-pull assembly and a sliding block 504. The push-pull assembly includes a fixed block 501 and a trapezoidal screw 502. The fixed block 501 is fixed to the top of the base plate 1. One end of the trapezoidal screw 502 is rotatably connected to the fixed block 501. The sliding block 504 is drivenly mounted on the trapezoidal screw 502, and both ends of the sliding block 504 are fixedly connected to two wedge blocks 204 respectively. A driven bevel gear 503 is also mounted on the trapezoidal screw 502. The rotation of the trapezoidal screw 502 can drive the sliding block 504 to slide on the trapezoidal screw 502. The sliding block 504 pushes and pulls the wedge blocks 204 to adjust the distance between the vertical moving block 202 and the limiting block 203, thereby adjusting the spinal manipulation pressure distance to meet the optimal pressure distance required by different patients' spines, so that the spinal manipulation pressure distance achieves the best spinal manipulation pressure massage effect for the patient.

[0039] The push-pull mechanism 5 also includes rotating components. Two rotating components are symmetrically installed on the top of the base plate 1. Each rotating component includes a mounting block 505, a handle rod 506, a driving bevel gear 507, and a first handle 508. The handle rod 506 is rotatably connected to the mounting block 505. Both ends of the handle rod 506 are connected to the driving bevel gear 507 and the first handle 508, respectively. The driving bevel gear 507 is fixedly fitted onto the end of the handle rod 506 near the driven bevel gear 503. The first handle 508 is fixedly installed on the end of the handle rod 506 away from the driven bevel gear 503. The driving bevel gear 507 meshes with the driven bevel gear 503, which is fixedly mounted on the trapezoidal lead screw 502. The mounting block 505 is fixedly installed on the top of the base plate 1. The first handle 508 facilitates the rotation of the handle rod 506. The rotation of the handle rod 506 drives the driving bevel gear 507 to rotate synchronously, which in turn drives the driven bevel gear 503 to rotate, thereby causing the trapezoidal lead screw 502 to rotate.

[0040] The rotating shaft mechanism 6 is connected to two locking blocks that cooperate with the locking components 302. There are two locking components 302 inside the movable seat 301, each cooperating with one of the two limiting seats 2. The locking components 302 press against the limiting seats 2 to generate the locking force required for the movable seat 301 to move. The movable seat 301 has a transverse through hole 3011, a square hole 3012 on one side, and two strip holes at the bottom. The locking components 302 are located within the through hole 3011. The through hole 3011 facilitates the installation of the locking components 302 so that they cooperate with the limiting seats 2.

[0041] The rotating shaft mechanism 6 drives two locking blocks to move in opposite directions. The locking blocks compress the locking component 302, thereby compressing the limiting seat 2 and generating the locking force that the moving seat 301 needs to overcome. By changing the position of the locking blocks, the magnitude of the locking force can be adjusted to control the intensity of the spinal manipulation massage, ensuring that the intensity of the spinal manipulation massage meets the patient's requirements and thus avoiding problems such as insufficient joint adjustment or overcorrection.

[0042] The limiting seat 2 also includes an L-shaped plate 201. The top of the vertical moving block 202 is provided with a fixed shaft 2022 that passes through the horizontal part of the L-shaped plate 201. A compression spring 2023 is sleeved on the fixed shaft 2022. L-shaped plate 201 is fixed to the top of base plate 1. The horizontal part of L-shaped plate 201 has a through hole for fixing shaft 2022 to pass through. Fixing shaft 2022 guides the lifting and lowering movement of vertical moving block 202. At the same time, when wedge block 204 is pushed between vertical moving block 202 and limiting block 203, vertical moving block 202 can move upward. Compression spring 2023 generates elastic force on vertical moving block 202 so that vertical moving block 202 can be tightly attached to wedge block 204. At the same time, when wedge block 204 is pulled horizontally from between vertical moving block 202 and limiting block, the compression spring 2023 can make vertical moving block 202 move downward and always keep it tightly attached to wedge block 204. This prevents vertical moving block 202 from becoming unstable when moving seat 301 drives locking component 302 to squeeze limiting seat 2, which would affect the abnormal change of locking force generated by locking component 302 squeezing limiting seat 2, and thus affect the effect of spinal manipulation massage on the patient.

[0043] The vertical moving block 202 and the limiting block 203 have an upper arc groove 2021 and a lower arc groove 2031 respectively on their inner sides. The wedge block 204 has two arc grooves 2041 symmetrically arranged on its inner side. The two arc grooves 2041, together with the upper arc groove 2021 and the lower arc groove 2031, form an upper locking groove 205 and a lower locking groove 206. The two arc-shaped grooves 2041 on the inner side of the wedge block 204 are located at its edge and are both set at an angle, ensuring that no matter how the wedge block 204 is pushed or pulled, the two arc-shaped grooves 2041 always form the upper locking groove 205 and the lower locking groove 206 with the upper arc groove 2021 and the lower arc groove 2031 respectively. The distance between the vertical moving block 202 and the limiting block 203 is the height of the lifting of the moving seat 301, which is the spinal adjustment pressure distance. By pushing and pulling the wedge block 204 to adjust the position of the wedge block 204 between the vertical moving block 202 and the limiting block 203, the spinal adjustment pressure distance can be adjusted to meet the optimal pressure distance required by the spine of different patients, ensuring that the spinal adjustment pressure distance achieves the best spinal adjustment pressure massage effect for the patient.

[0044] The locking assembly 302 includes a spring 3021 and a locking ball 3023 arranged sequentially from the inside to the outside. The first detection module includes a pressure sensor 3022, which is disposed between the spring 3021 and the locking ball 3023. The pressure sensor 3022 is fixed to the spring 3021 and the locking ball 3023 respectively. The locking ball 3023 corresponds to the upper locking groove 205 or the lower locking groove 206 on the same side. The diameter of the locking ball 3023 matches the diameter of the through hole 3011 in the movable seat 301. The output end of the pressure sensor 3022 extends out of the corresponding strip hole and connects to the input end of the control unit.

[0045] The locking ball 3023, through the through hole 3011, cooperates with the upper locking groove 205 or the lower locking groove 206. By controlling the deformation of the spring 3021, the locking force generated by the locking ball 3023 pressing the limiting seat 2 can be adjusted, thereby achieving the effect of controlling the pressure of the spine straightening.

[0046] During spinal manipulation massage, when the mattress 305 is at its lowest point, the locking ball 3023 is located in the lower locking groove 206 and is tangentially locked to the lower locking groove 206. When the moving seat 301 moves upward, the locking ball 3023 moves from the lower locking groove 206 into the upper locking groove 205. The upper locking groove 205 and the lower locking groove 206 lock and limit the locking ball 3023, thereby limiting the movement of the moving seat 301.

[0047] The rotating shaft mechanism 6 includes a connecting seat 601, a handwheel shaft 602, a driven shaft 605, a driven gear 606, and a driving gear 604. Two connecting seats 601 are symmetrically arranged on one side of the movable seat 301, and two driving gears 604 are symmetrically arranged on the handwheel shaft 602. The handwheel shaft 602 is rotatably connected to the connecting seat 601. A driven shaft 605 is provided between the handwheel shaft 602 and the movable seat 301. The driven shaft 605 is rotatably connected to the two connecting seats 601. Specifically, the upper end of the connecting seat 601 is fixed to the supporting steel plate, and a driven shaft 605 is installed on the opposite side of the two connecting seats 601. There are two driven shafts 605. The driven gear 606 is arranged on the driven shaft 605 and meshes with the driving gear 604. Handles 603 are installed at both ends of the handwheel shaft 602. When the operator turns the handwheel shaft 602, the handwheel shaft 602 drives the two driven shafts 605 to rotate simultaneously through the cooperation of the driving gear 604 and the driven gear 606.

[0048] Locking blocks are slidably mounted on the two driven shafts 605 respectively. The two locking blocks are in a state of opposite movement or relative movement. One end of the two locking blocks extends into the interior of the movable seat 301 and presses against the opposite ends of the two springs 3021. A slide rail assembly 609 is provided on the top of the locking blocks. The slide rail assembly 609 is used to guide the movement of the locking blocks. The locking block includes a locking slider 607 and a pressure block 608 installed inside the locking slider 607. The pressure block 608 is vertically fixed inside the locking slider 607. The two driven shafts 605 are screw structures with opposite thread directions. The locking slider 607 is threaded onto the driven shafts 605. One end of the pressure block 608 extends through the square hole 3012 into the interior of the moving seat 301 and presses against the end of the spring 3021 on the same side. When the two driven shafts 605 rotate, they drive the two locking sliders 607 to move in opposite directions or in opposite directions. The locking sliders 607 drive the pressure block 608 to move simultaneously. Changing the position of the pressure block 608 can change the degree of compression of the spring 3021 by the pressure block 608, increasing or decreasing the compression force of the spring 3021, thereby adjusting the locking force generated by the locking ball 3023 pressing against the vertical moving block 202 or the limiting block 203.

[0049] The handwheel shaft 602 drives the drive gear 604 to rotate, the drive gear 604 drives the driven gear 606 to rotate, and the driven gear 606 drives the driven shaft 605 to rotate, so that the locking slider 607 moves laterally on the driven shaft 605. This causes the locking slider 607 to drive the pressure block 608 to move along the length of the square hole 3012, compressing or releasing the compression force of the spring 3021, thereby adjusting the locking force generated by the locking ball 3023 pressing against the limit seat 2.

[0050] The slide rail assembly 609 includes a guide slider 6092 fixed to the top of the locking slider 607 and a guide rail 6091 slidably connected to the guide slider 6092. The guide rail 6091 is closed at both ends. The guide slider 6092 cooperates with the guide rail 6091 to guide the movement of the locking slider 607. When the locking slider 607 moves, it drives the guide slider 6092 to slide on the guide rail 6091, ensuring that the locking slider 607 moves horizontally. The upper end of the guide rail 6091 is fixed to the supporting steel plate 304.

[0051] The lifting mechanism 4 includes a power component, a side plate 401, a bearing, a position sensing plate 404, and a conical cam 405. The conical cam 405 is connected to the power component, and the power component drives the conical cam 405 to rotate, which is used to lift the movable seat 301. The tapered cam 405 has a "~" shaped structure. The arc surface of the tapered cam 405 contacts the ball bearing 303 and is used to lift the ball bearing 303. The arc surface of the tapered cam 405 is the path of movement of the ball bearing 303. The side plate 401 and the base plate 1 are fixed. The power assembly drives the position sensing plate 404 to rotate. The position sensing plate 404 and the side plate 401 are parallel. The second detection module includes a magnet 7 and a Hall sensor 8. The magnet 7 is fixedly disposed on the side of the position sensing plate 404 facing the side plate 401, and the Hall sensor 8 is fixedly disposed on the side of the side plate 401 facing the position sensing plate 404. The output terminal of the Hall sensor 8 is connected to the input terminal of the control unit 9. The power assembly includes a motor 402, which is controlled by the control unit 9. In this embodiment, the ball bearing 303 is a universal ball bearing.

[0052] like Figure 14 and 15 As shown, a conical cam moving mechanism is fixedly provided at the lower end of the sliding block 504. The conical cam moving mechanism includes a fixed plate 10 and a protective frame 11. The conical cam moving mechanism is used to drive the conical cam 405 to move with the sliding block 504.

[0053] The longitudinal section of the tapered cam 405 is a cone shape with one end larger than the other, the larger end being closer to the fixed plate 10 and the smaller end being farther away from the fixed plate 10.

[0054] Motor 402 is mounted on base plate 1. The output shaft of motor 402 is connected to hollow shaft reducer 12. A first rotating shaft 13 and a second rotating shaft 14 are respectively provided on both sides of conical cam 405. One end of each of the first rotating shaft 13 and the second rotating shaft 14 adopts a flat key structure. Conical cam 405 is fixed to the first rotating shaft 13 and is movably connected to hollow shaft reducer 12 via the first rotating shaft 13. The first rotating shaft 13 is connected to fixed plate 10 via bearings. The upper end of fixed plate 10 movably passes through base plate 1 and is fixed to sliding block 504 by bolts. When sliding block 504 moves, fixed plate 10 drives first rotating shaft 13 and conical cam 405 to move accordingly. First rotating shaft 13 moves within hollow shaft reducer 12.

[0055] A keyway is provided on the other side of the tapered cam 405, and a second rotating shaft 14 is provided in the keyway. A position sensing plate 404 is fixedly installed on the second rotating shaft 14, and the second rotating shaft 14 is connected to the side plate 401 through a bearing. A protective frame 11 is fixedly installed on the fixed plate 10. The protective frame 11 has a U-shaped structure and is fitted around the outer periphery of the tapered cam 405.

[0056] In this embodiment, there are two pressure sensors 3022, which are NSPAD1N series pressure sensors. The Hall sensor 8 is an Elecware ESHM1250 Hall-effect speed sensor. The control unit 9 includes a microcontroller, a touchscreen, and a driver chip. Specifically, the microcontroller is an STM32 microcontroller, the touchscreen is a TP6037C touchscreen, and the driver chip is an L298N driver chip. The pressure sensor 3022 and the STM32 microcontroller communicate via I2C serial port. The ADC pin of the STM32 microcontroller is connected to the Hall sensor 8, and the STM32 microcontroller and the TP6037C touchscreen communicate via UART serial port. To facilitate control of the motor 402, the output of the STM32 microcontroller is connected to the L298N driver chip, and the motor 402 is connected to the power supply through the L298N driver chip to form a circuit.

[0057] The working principle of this invention is as follows: In the initial state, the patient's back is against the mattress 305, which is in its initial position. At this time, the locking ball 3023 is located in the lower locking groove 206 and is tangentially locked to it. Simultaneously, the ball bearing 303 is tangential to the groove of the tapered cam 405 (e.g., ...). Figure 5 (As shown). Next, the lifting mechanism 4 drives the pressing mechanism 3 to perform the lifting operation. A working signal is sent through the touchscreen, and the microcontroller powers the motor 402 via the driver chip. The output shaft of the motor 402 drives the conical cam 405 to rotate. The arc surface of the conical cam 405 lifts the ball bearing 303, which in turn moves the moving seat 301 upwards. The moving seat 301 then moves the supporting steel plate 304 and the mattress 305 upwards. Simultaneously, the locking ball 3023 moves upwards with the moving seat 301. The locking ball 3023 passes through the limiting block 203 and the wedge block 204 and enters the upper locking groove 205, limiting the moving seat 301 and preventing it from falling back due to gravity (e.g., ...). Figure 6 (As shown). The conical cam 405 rotates in a circular motion. After lifting the ball bearing 303, it only contacts the ball bearing 303 and cannot continue to raise the ball bearing 303. At the same time, the position sensing plate 404 rotates with the motor 402. When the magnet 7 reaches the position of the Hall sensor 8, the Hall sensor 8 outputs an electrical signal. This indicates that the conical cam 405 has rotated 360° and returned to its original position. At this time, the ball bearing 303 is in a suspended state. The microcontroller uses the drive chip to power off and stop the motor 402. At this time, the patient's back is lifted by the mattress 305, and the preparation is complete. Finally, the medical staff applies spinal manipulation to the patient's body to make the patient feel downward force. The patient's back presses down on the mattress 305. When the pressure is greater than the locking force, the locking ball 3023 moves downward with the moving seat 301 and returns from the upper locking groove 205 to the lower locking groove 206. The ball bearing 303 then resets and becomes tangent to the groove of the conical cam 405 (as shown). Figure 5 (As shown).

[0058] After completing a spinal manipulation and pressure massage, the doctor can ask the patient about their feelings to determine whether the pressure distance and pressure intensity of the pressure mechanism 3 meet the patient's requirements for spinal manipulation and pressure massage. If not, the doctor can adjust the pressure distance and pressure intensity to find the appropriate pressure distance and pressure intensity that meet the patient's needs.

[0059] Example 2 The pressure distance is a height distance. The longer the pressure distance, the higher the patient's back is supported by the mattress 305, thus obtaining a greater pressure distance when the patient's back is pressed down.

[0060] Based on the variable distance and torque spine straightening and pressing device in Example 1, the adjustment of the pressing distance is explained: Rotating the handle rod 506 via the handle 508 causes the drive bevel gear 507 to rotate, which in turn drives the driven bevel gear 503 to rotate. The driven bevel gear 503 then drives the trapezoidal lead screw 502 to rotate, causing the sliding block 504 to move on the trapezoidal lead screw 502. The sliding block 504 then drives the wedge block 204 to move between the vertical moving block 202 and the limiting block 203. Figure 8 As shown, there is a gap between the upper end face of the vertical moving block 202 and the lower end face of the horizontal part of the L-shaped plate 201, and a fixed shaft 2022 and a compression spring 2023 are provided. As the wedge block 204 moves forward and backward, and the compression spring 2023 is passively extended and compressed, the height of the vertical moving block 202 from the limiting block 203 changes accordingly. Therefore, the stroke of the moving seat 301 changes accordingly, and the change in the pressing distance can directly change the treatment effect, improving the flexibility and accuracy of treatment.

[0061] When the sliding block 504 moves, the fixed plate 10 drives the first rotating shaft 13 and the conical cam 405 to move accordingly. The height of the "~" shaped curved surface of the conical cam 405 gradually decreases as it moves away from the fixed plate (i.e., the larger end of the conical cam 405 is closer to the fixed plate 10, and the smaller end is farther away from the fixed plate 10). When the wedge block 204 moves forward, the height of the vertical moving block 202 from the limiting block 203 increases, and the ball bearing 303 rises. At this time, as the sliding block 504 moves forward, the conical cam 405 moves forward, and the ball bearing 303 contacts the larger end of the conical cam 405. Conversely, when the wedge block 204 moves backward, the ball bearing 303 contacts the smaller end of the conical cam 405.

[0062] Example 3 The locking ball 3023 compresses the limiting block 203 or the vertical moving block 202 to generate a locking force, and the pressure torque is changed by adjusting the locking force. When the pressure distance remains constant, the greater the locking force, the stronger the stimulation. Based on the variable distance and torque spine straightening pressure device in Example 1, the adjustment of the pressure torque is explained as follows: like Figure 4 and 7 As shown, by rotating the handwheel shaft 602 via the handle 603, the rotation of the handwheel shaft 602 drives the two drive gears 604 to rotate. The drive gears 604 drive the driven gears 606 to rotate, and the driven gears 606 drive the driven shaft 605 to rotate. The locking slider 607 moves on the driven shaft 605, so that the locking slider 607 drives the pressure block 608 to move to compress or release the compression force of the spring 3021, thereby controlling the deformation of the spring 3021 and increasing or decreasing the locking force generated by the locking ball 3023 pressing the limiting block 203 or the vertical moving block 202, thus completing the adjustment of the pressure torque.

[0063] Because the relationship between locking force and momentary pressure torque cannot be visually displayed, medical staff need to repeatedly adjust the locking force. To solve this problem, in this embodiment, two pressure sensors 3022 detect the locking force (the pressure between the spring 3021 and the locking ball 3023) in real time. The pressure sensors 3022 send the detected parameters to the microcontroller, which calculates the momentary pressure torque intensity value and displays it on the touchscreen.

[0064] Specifically, the change in locking force when the locking ball 3023 moves between the limiting block 203 and the vertical moving block 202 can be simply transformed into a sinusoidal curve. The locking force of the locking ball 3023 is at its maximum when it is about to enter the upper locking groove 205 or the lower locking groove 206, which is F1 and F2. The locking force is at its minimum when the locking ball 3023 falls into the upper locking groove 205 or the lower locking groove 206, which is F3 and F4.

[0065] The microcontroller obtains the maximum and minimum locking forces F1 and F2, and the minimum and minimum locking forces F3 and F4, and calculates the tensile torque F using formula (1): F = A(F1-F3) + B(F2-F4) (1); Among them, the two constants A and B are obtained from the friction coefficients between the locking ball 3023 and the upper locking groove 205 and the lower locking groove 206.

[0066] By viewing the pressure torque intensity value displayed on the touchscreen, medical staff can better determine the current pressure torque intensity and ensure that the pressure torque intensity meets the patient's requirements for spinal manipulation massage.

[0067] The embodiments described above are merely preferred embodiments of the invention and are not intended to limit the scope of the invention. Therefore, any equivalent changes or modifications made to the technical solutions described in the claims of this invention should be included within the scope of the patent application of this invention.
