Description

Technical Field

[0001] The present application relates to the technical field of compression beds, and in particular to a semi-automatic compression chiropractic bed. Background Art

[0002] Physiotherapy beds play an important role in the treatment and rehabilitation of spinal diseases. They are modified based on ordinary hospital beds and provide powerful tools for chiropractors. They help to achieve manual reduction of vertebrae and are of great significance for restoring the physiological curvature of the spine and promoting the rehabilitation of vertebral subluxation.

[0003] For example, the authorization publication number CN222092089U discloses a multifunctional chiropractic and pressing bed, which includes a base with a lift installed on the base, a bed frame installed at the lifting end of the lift, and the bed frame is divided into a back bed frame, a leg bed frame, and a head bed frame. The three-section bed frame is equipped with a chiropractic and pressing device, which includes a lifting motor, which is fixedly connected to the back bed frame, and a cam is fixedly installed on the output shaft of the lifting motor. The function of the lifting motor is to use the cam to lift the back bed frame.

[0004] However, the above-mentioned pressing beds have many functions and are easy to operate. They need to use electrical control to realize various functions and mostly rely on motors to drive the lifting or pressing functions, which makes the equipment bulky and heavy. They are only suitable for fixed installation in stores and cannot meet the portability needs of door-to-door services or home use.

[0005] In addition, although there are simple foldable physiotherapy beds in the existing technology, they are easy to carry but lack adaptive adjustment functions. The physiotherapist needs to manually and repeatedly adjust the support strength of the bed frame at the corresponding parts. The operation is cumbersome and relies on experience. When encountering a heavier client, a stronger support force may be required to prevent the bed frame from sinking excessively. The traditional mechanical structure requires manual intervention to adjust the spring preload, which is inefficient, cumbersome and time-consuming to operate, and the treatment effect is easily affected by human error. Summary of the Invention

[0006] In order to realize some semi-automatic adjustment functions of a portable physiotherapy bed, a semi-automatic pressure-controlled chiropractic physiotherapy bed is provided.

[0007] The above-mentioned application objectives of this application are achieved through the following technical solutions: A semi-automatic pressure-releasing chiropractic treatment bed comprises a support plate, a plurality of support bed bodies are provided above the support plate, the support plates are provided with at least two, two adjacent support plates are hingedly connected, a support frame is provided below the support plates and can be folded below the support plates, one side of the support bed body is hingedly connected to the support plate, and a pressure-releasing mechanism is provided below the support plate away from the side hinged to the support bed body; The pressing mechanism includes a pressing block and a sliding rod, the sliding rod is vertically slidably arranged in the pressing block, the outer wall of the sliding rod is provided with at least two notches along its own sliding direction, the pressing block is provided with a movable groove perpendicular to the sliding direction of the sliding rod, a first spring is provided in the movable groove, one end of the first spring is provided with a first steel ball abutting against the notch, and the other end of the first spring is provided with a sliding block sliding in the movable groove; The invention also includes a lifting mechanism and an adjusting mechanism for lifting and supporting the bed body and the sliding rod, the adjusting mechanism includes a trigger rod and a trigger ring, the trigger rod is vertically slidably arranged in the pressure block, the trigger ring slides on the outer wall of the trigger rod, a limiting ridge is fixedly provided on the inner wall of the bottom of the trigger ring, and two relatively parallel limiting slides are provided on the outer wall of the top of the trigger rod, and the limiting ridge is slidably rotated along the circumference of the trigger rod between the two limiting slides, and the vertical distance between the top of the trigger ring and the upper surface of the pressure block is greater than the vertical distance between the top of the slide rod and the upper surface of the pressure block; The lower end of the trigger rod is provided with a wedge-shaped block abutting against the upper end of the sliding block, the outer wall of the trigger rod is provided with a plurality of limit notches along its own sliding direction, the inner edge of the pressure block is provided with a limit groove perpendicular to the sliding direction of the trigger rod, a second spring is provided in the limit groove, and one end of the second spring is provided with a second steel ball abutting against the limit notch, and the other end of the second spring is fixed to the inner wall of the pressure block.

[0008] By adopting the above technical solution, the articulated support plate and the foldable support frame enable the bed to be quickly stored into a compact shape, which is convenient for transportation and storage, while maintaining structural stability. The portable design is suitable for primary medical or home scenarios, expanding the application range of the bed. At the same time, when the customer lies down on the support bed, the support bed will first press against the top of the trigger ring, and the trigger ring and the trigger rod rely on the abutment cooperation between the limiting ridge and the limiting slide to make the trigger ring and the trigger rod move coaxially and synchronously. Customers with different weights will apply different pressures to the trigger ring, and the customer's weight is transmitted to the trigger rod through the trigger ring. The downward movement distance of the trigger rod is proportional to the weight, and the trigger rod is The wedge block abuts against the sliding block, and the compression amount of the first spring is dynamically adjusted with the sliding block, thereby achieving adaptive matching of the pressing force of the first steel ball on the notch and the customer's gravity. When the trigger rod moves downward, the second steel ball will be engaged with the limiting notches at different heights according to the customer's weight, ensuring that the trigger rod continues to apply downward pressure. After the trigger ring supports the customer to determine the weight for the first time, the trigger ring is rotated to make the limiting ridge slide out of the limiting slide, and the trigger ring can slide into the pressure block along the axis of the trigger rod, reducing the risk of interference between the supporting bed and the trigger ring. There is no need to know the customer's weight in advance. The supporting force can be adjusted in real time through mechanical linkage, avoiding manual trial and error, and improving the convenience of treating customers with the pressure bed.

[0009] Preferably, the jacking mechanism includes a connecting rod, one end of the connecting rod is located outside the support plate, and a jacking block is fixed to the other end of the connecting rod, the upper surface of the jacking block abuts against the support bed body, and a connecting rod is fixed to the side of the sliding rod facing the jacking block, and a reset groove is opened on the side of the lifting block facing the sliding rod along its own rotation direction, and the end of the connecting rod is embedded in the reset groove and slides.

[0010] By adopting the above technical solution, a connecting rod and a lifting block are provided to facilitate jacking operation from outside the support plate. The connecting rod is rotated to rotate the lifting block at the end of the connecting rod to abut against the support bed for jacking. The lifting block synchronously drives the sliding rod to lift through the connecting rod, so that the support bed and the sliding rod can be synchronously lifted by relying on the rotation of the connecting rod.

[0011] Preferably, the supporting bed body comprises a shoulder bed body, a waist bed body and a leg bed body, and a pressing mechanism, an adjusting mechanism and a lifting mechanism are respectively provided below the shoulder bed body, the waist bed body and the leg bed body.

[0012] By adopting the above technical solution, a shoulder bed, a waist bed and a leg bed are set up to carry out chiropractic treatment for different parts of the body; a pressure mechanism, an adjustment mechanism and a lifting mechanism are set under each bed, which can adaptively adjust the pressure and chiropractic treatment for different parts, meet the needs of non-electric control, and reduce the constraints of usage scenarios.

[0013] Preferably, a rotating rod is fixed on the top outer wall of the trigger ring, and a placement groove for the rotating rod to rotate is opened on the upper surface of the pressure block.

[0014] By adopting the above technical solution, a rotating rod and a placement slot are provided, which facilitates the rotation operation of the trigger ring. The chiropractor controls the rotation of the rotating rod to lock and unlock the trigger ring and the trigger rod, thereby adjusting the semi-automatic compression chiropractic function of the physiotherapy bed. In addition, the placement slot can provide rotation space for the rotating rod to ensure smooth operation.

[0015] Preferably, a handle is fixed on the outer side wall of the support plate.

[0016] By adopting the above technical solution, a handle is fixed on the outer side wall of the support plate, which makes it easier for users to carry and transport the semi-automatic compression chiropractic bed, improves portability, and reduces the limitations of the use of the bed.

[0017] Preferably, it also includes a fine-tuning mechanism, which includes a fixing nut and an adjusting rod, the fixing nut is fixed in the movable groove, the adjusting rod is threadedly connected to the fixing nut, the wedge block slides axially along the adjusting rod at the bottom end of the trigger rod, and the end of the adjusting rod facing the fixed tube is provided with a transmission block abutting against the wedge block, and the other end of the adjusting rod passes through to the outside of the pressure block.

[0018] By adopting the above technical solution, on the basis of setting the pressure block, sliding rod, top pressure mechanism and automatic adjustment mechanism to achieve stable support for customers with different weights, a fine-tuning mechanism consisting of a fixed nut, an adjustment rod and a transmission block is added. By rotating one end of the outer end of the adjustment rod, the fine-tuning mechanism controls the displacement of the wedge block through the pitch of the adjustment rod, thereby achieving linear fine-tuning of the steel ball pressing force, compensating for the support force deviation caused by individual weight differences or mechanical wear, combining manual fine-tuning with automatic adjustment, taking into account both efficiency and precision, and extending the service life of the device. Preferably, a separation groove is provided on the outer wall of the trigger ring in the vertical direction. The separation groove is located on one side of the limiting notch along the circumference of the trigger ring, and the inner wall at the top of the separation groove is higher than the limiting notch at the top of the trigger rod in the vertical direction.

[0019] By adopting the above technical solution, the trigger ring is rotated so that its outer wall axially covers the limit recess, so that the second steel ball can abut against the outer wall of the trigger ring, thereby separating the second steel ball from the limit recess and preventing the second steel ball from being stuck in the limit recess. At this time, the first spring releases its elastic potential energy to drive the sliding block to squeeze the wedge block, and synchronously drive the trigger rod to rise and reset. After the trigger rod rises and resets, the trigger ring is rotated again so that the outer wall of the trigger ring no longer abuts the second steel ball, and the second steel ball abuts against the limit recess at the bottom end of the trigger rod again. Before facing different customers, the trigger rod can be reset in the axial direction by rotating the trigger ring in the pressure block. Regardless of the customer's weight, the second steel ball can be pressed against the limit recess at the lowest end to adapt to the adjustment of weight from light to heavy.

[0020] Preferably, an upper surface of the sliding rod and an upper surface of the trigger ring are both provided with an arc-shaped top.

[0021] By adopting the above technical solution, an arc-shaped support is provided on the upper surface of the sliding rod and the trigger ring. When the supporting bed is pressed against the sliding rod or the trigger ring, the contact area between the supporting bed and the upper end of the sliding rod and the trigger ring can be increased, so that the sliding rod and the trigger ring can fit the surface of the bed better when lifting the supporting bed, ensuring the stability of the supporting bed's pressing process and improving the performance and reliability of the semi-automatic pressing chiropractic physiotherapy bed.

[0022] Preferably, the depth of the limiting recess in the axial direction of the locking rod increases from shallow to deep from bottom to top.

[0023] By adopting the above technical solution, when the trigger rod slides up and down, as the position changes, the depth of the limiting recess changes from shallow to deep from bottom to top, and the second steel ball cooperates with the limiting recess to achieve different degrees of limitation. The position of the trigger rod can be accurately adjusted, and the pressure of the first steel ball on the recess can be adjusted conveniently to quickly adapt to different customer weights and improve work efficiency.

[0024] Preferably, connecting rings are fixed on the outer walls at both ends of the trigger ring.

[0025] By adopting the above technical solution, when the trigger ring is rotated and lowered into the pressure block, the upper connecting ring can abut against the upper surface of the pressure block to prevent the trigger ring from falling completely into the pressure block; when the trigger ring is rotated and raised, the lower connecting ring can abut against the inner wall of the pressure block, reducing the risk of the trigger ring slipping out of the pressure block, so that the trigger ring can slide stably in its own axial direction in the pressure block, thereby enhancing the stability between the trigger ring and the pressure block.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The support plates are hinged and the support frame is foldable, making the physiotherapy bed easy to carry. This solves the problem of traditional physiotherapy beds being heavy and bulky and inconvenient to carry, reduces usage limitations, and further facilitates storage and carrying of the physiotherapy bed. 2. The pressing mechanism and the adjustment mechanism work in conjunction. When the user lies on the support bed, their weight is transferred to the trigger lever via the trigger ring. The trigger lever presses down on the wedge block, which pushes the sliding block to compress the first spring, thereby dynamically adjusting the pressure of the first steel ball on the sliding rod notch. Different weights of users will cause the trigger lever to move down to different distances, which in turn causes the compression of the first spring to adaptively change, ensuring that the support force is precisely matched to the user's weight. 3. The fine-tuning mechanism allows manual fine-tuning of the wedge position, thereby precisely controlling the initial preload of the first spring. The threaded adjustment rod linearly adjusts the displacement of the wedge when rotated, achieving precise calibration of the support force. After long-term use, the spring or steel ball may fatigue. The fine-tuning mechanism restores the optimal clamping force, extending the life of the equipment. 4. Rotating the trigger ring so that its outer wall axially covers the limit notch allows the second steel ball to abut against the outer wall of the trigger ring, thereby separating the second steel ball from the limit notch. The first spring releases its elastic potential energy, driving the sliding block to squeeze the wedge block, synchronously driving the trigger rod to rise and reset. After the trigger rod rises and resets, the trigger ring is rotated again so that the outer wall of the trigger ring no longer abuts the second steel ball, and the second steel ball abuts the limit notch at the bottom end of the trigger rod. When facing different customers, rotating the trigger ring in the pressure block can achieve axial reset of the trigger rod. Regardless of the customer's weight, the second steel ball can be pressed against the lowest limit notch to accommodate weight adjustment from light to heavy.

DETAILED DESCRIPTION The following is a further detailed description with reference to the accompanying drawings: As attached Figure 1 and attached Figure 2 As shown, a semi-automatic pressure chiropractic bed includes several support plates 1, two of which are hinged to each other. The support plates 1 are support platforms, generally made of wood or metal. Several support beds 2 are arranged above the support plates 1. The support beds 2 are platforms for customers to lie on. Soft cushions can be laid on the surface of the support beds 2 to improve the customer's comfort. One side of the support bed 2 is hinged to the support plate 1. Five support beds are arranged here. The body 2 is respectively composed of a head bed body 21, a shoulder bed body 22, a waist bed body 23, a leg bed body 24 and a foot bed body 25. A support frame 3 that can be folded under the support plate 1 is provided under the support plate 1. A foldable support frame 3 is provided under the support plate 1. The support frame 3 can be folded into the support plate 1. The support frame 3 is unfolded and the jacking mechanism 5 is adjusted to raise the support bed body 2 to an appropriate height. The support frame 3 is folded to the bottom of the support plate 1, and the support bed body 2 is fitted with the support plate 1, forming a compact shape as a whole, which is convenient for transportation.

[0028] Handles 11 are respectively fixed on the outer side walls of the two support plates 1, which facilitate users to carry and transport the semi-automatic compression chiropractic bed, improve portability, and reduce limitations in the use of the bed.

[0029] The shoulder bed 22, the waist bed 23 and the leg bed 24 are located below the side away from the hinged side of the support bed 2, and are respectively provided with a pressing mechanism 4 and a lifting mechanism 5. The shoulder bed 22, the waist bed 23 and the leg bed 24 are provided so that chiropractic treatment can be carried out for different parts of the body; a pressing mechanism 4 and a lifting mechanism 5 are respectively provided under each bed, which can adaptively adjust the pressing and chiropractic treatment for different parts.

[0030] As attached Figure 3 and attached Figure 4 As shown, the pressing mechanism 4 includes a pressing block 41 and a slide rod 42. The pressing block 41 is a rectangular block. The pressing block 41 is made of high-strength metal material. The slide rod 42 slides vertically through the pressing block 41. The slide rod 42 is made of metal and its surface is smoothed to reduce friction with the pressing block 41. The outer wall of the slide rod 42 has at least two notches 421 along its own sliding direction. The shape of the notch 421 is a waist shape that passes through the slide rod 42.

[0031] The lifting mechanism 5 includes a connecting rod 51 and a lifting block 52. One end of the connecting rod 51 passes through the pressure block 41 to the middle of the support plate 1, and the other end of the connecting rod 51 is located outside the support plate 1, which is convenient for the chiropractor to control. The connecting rod 51 can rotate on the pressure block 41, and a lifting block 52 is fixed on one end of the connecting rod 51 passing through the pressure block 41. The lifting block 52 is fan-shaped. When the connecting rod 51 is rotated, the connecting rod 51 can synchronously drive the lifting block 52 to lift the supporting bed body 2, and a connecting rod 53 is fixed to the side of the sliding rod 42 toward the lifting block 52. The connecting rod 53 is located on the side of the sliding rod 42 opposite to the notch 421. The lifting block 52 is provided with a reset groove 521 along its own rotation direction, and the end of the connecting rod 53 is embedded in the reset groove 521 for sliding. Therefore, when the connecting rod 51 is rotated, the sliding rod 42 and the supporting bed body 2 can be synchronously driven to lift synchronously.

[0032] As attached Figure 4 and attached Figure 5As shown, a pressing mechanism 6 and an adjusting mechanism 7 are provided in the pressing block 41. A movable groove 411 is provided in the pressing block 41 along a direction perpendicular to the sliding direction of the slide rod 42. The cross section of the movable groove 411 in the direction perpendicular to the sliding direction of the slide rod 42 is circular. The movable groove 411 is connected to the inner groove of the sliding arrangement of the slide rod 42. The pressing mechanism 6 includes a first spring 61 located in the movable groove 411. The inner wall of the movable groove 411 is used to limit the bending of the first spring 61 in the radial direction to ensure that the first spring 61 acts in the axial direction of the movable groove 411. One end of the first spring 61 is provided with a spring that abuts against the notch 421. The first steel ball 62 is abutted against the notch 421 near the bottom end. The first steel ball 62 has good wear resistance. The first steel ball 62 abuts against the notch 421 to achieve the positioning of the slide rod 42. The other end of the first spring 61 is provided with a sliding block 63 that slides in the movable groove 411. The sliding block 63 slides in the movable groove 411. The upper surface of the sliding block 63 is set to an inclined shape. The elastic force of the first spring 61 makes the first steel ball 62 abut against the notch 421 of the slide rod 42, and the sliding block 63 slides in the movable groove 411 as the first spring 61 expands and contracts.

[0033] When the locking cam 73 is in the unlocked position, the locking cam 78 is in the unlocked position, and the locking cam 78 is in the unlocked position, so that the locking cam 78 is locked and the locking cam 78 is in the unlocked position.

[0034] As attached Figure 5 and attached Figure 6 As shown, a sliding groove 711 is opened axially along the movable groove 411 at the bottom end of the trigger rod 71, and a sliding shaft 712 is provided in the sliding groove 711 for horizontal sliding. The sliding shaft 712 is arranged perpendicular to the notch 421 of the sliding groove 711. The upper end of the wedge block 73 is connected to the sliding shaft 712 through a connecting shaft 713, and the diameter of the connecting shaft 713 is smaller than that of the sliding groove 711. In this way, when the wedge block 73 moves horizontally, the wedge block 73 can drive the sliding shaft 712 and the connecting shaft 713 to slide horizontally in the sliding groove 711, ensuring that the wedge block 73 slides stably on the bottom end of the trigger rod 71.

[0035] The inner portion of the pressure block 41 is provided with a limiting groove 412 perpendicular to the sliding direction of the trigger rod 71. One end of the limiting groove 412 is communicated with the inner groove of the trigger rod 71 slidingly provided on the pressure block 41, and the cross section of the limiting groove 412 perpendicular to the axial direction of the trigger rod 71 is circular. The outer wall of the trigger rod 71 is provided with a plurality of limiting notches 716 along its own sliding direction. The limiting notches 716 are set to be waist-shaped and pass through the trigger rod 71. A second spring 74 is slidably provided in the limiting groove 412, and one end of the second spring 74 is provided with a second steel ball 75 abutting against the limiting notch 716. The other end of the second spring 74 is fixed to the inner wall of the pressure block 41. The second spring 74 and the second steel ball 75 are fixed to the inner wall of the pressure block 41. The cooperation of the two parts can make the trigger rod 71 be locked in different positions, and the depth of the limiting recess 716 in the axial direction of the limiting groove 412 changes from shallow to deep from bottom to top, so that the limiting groove 412 can adapt to the customer's weight and be engaged in the limiting recess 716 of corresponding depth. The second steel ball 75 is engaged in the limiting recess 716, which can realize the locking of the trigger rod 71 in the axial lifting. After the limiting groove 412 limits and locks the trigger rod 71, the trigger rod 71 is stably pressed against the sliding block 63 by the wedge block 73. When the first steel ball 62 switches to press against different notches 421, the pressure applied by the first spring 61 to the first steel ball 62 remains stable.

[0036] As attached Figure 3 and attached Figure 7 When the locking cam 721 is in the state of being rotated, the locking cam 721 is in the state of being rotated, and the locking cam 721 is in the state of being rotated.

[0037] Connecting rings 722 are fixed on the outer walls of both ends of the trigger ring 72. When the trigger ring 72 is rotated and lowered into the pressure block 41, the upper connecting ring 722 can abut against the upper surface of the pressure block 41 to prevent the trigger ring 72 from falling completely into the pressure block 41; when the trigger ring 72 is rotated and raised, the lower connecting ring 722 can abut against the inner wall of the pressure block 41, reducing the risk of the trigger ring 72 slipping out of the pressure block 41, so that the trigger ring 72 can slide stably in its own axial direction inside the pressure block 41.

[0038] The upper surface of the trigger ring 72 and the upper surface of the slide bar 42 are both provided with an arc-shaped support 9. When the support bed 2 presses against the slide bar 42 or the trigger ring 72, the contact area between the support bed 2 and the upper end of the slide bar 42 and the trigger ring 72 can be increased, so that the slide bar 42 and the trigger ring 72 can fit more closely to the surface of the bed when lifting the support bed 2, ensuring the stability of the pressure process of the support bed 2.

[0039] A rotating rod 724 is fixed on the top outer wall of the trigger ring 72, and a placement groove 413 for the rotating rod 724 to rotate is opened on the upper surface of the pressure block 41. The placement groove 413 can provide a rotation space for the rotating rod 724, which can facilitate the rotation operation of the trigger ring 72. The chiropractor controls the rotation of the rotating rod 724 to achieve locking and unlocking of the trigger ring 72 and the trigger rod 71, thereby adjusting the semi-automatic pressure chiropractic function of the physiotherapy bed.

[0040] As attached Figure 7 As shown, a separation groove 723 is provided on the outer wall of the trigger ring 72 in the vertical direction. The separation groove 723 is located on one side of the limiting notch 716 along the circumference of the trigger ring 72. The inner wall of the top of the separation groove 723 is higher than the limiting notch 716 at the top of the trigger rod 71 in the vertical direction, and the side wall of the separation groove 723 facing the limiting notch 716 is provided with a chamfer, which is conducive to the second steel ball 75 to separate from the limiting notch 716 and reduce the occurrence of the jamming phenomenon. After the trigger ring 72 rotates circumferentially along the trigger rod 71, the groove wall of the separation groove 723 facing the limiting notch 716 abuts against the second steel ball 75. Under the force of the rotation of the trigger ring 72 When the lever 72 is unlocked, the second spring 75 is forced to separate from the corresponding limit notch 716. The first spring 61 releases its elastic potential energy to drive the sliding block 63 to squeeze the wedge block 73, and simultaneously drives the trigger rod 71 to rise and reset. After the trigger rod 71 rises and resets, the trigger ring 72 is rotated again so that the separation plate no longer separates the second steel ball 75. The second steel ball 75 is again abutted against the limit notch 716 at the bottom end of the trigger rod 71. By rotating the trigger ring 72 in the pressure block 41, the trigger rod 71 can be reset in the axial direction. Regardless of the customer's weight, the second steel ball 75 can be pressed against the limit notch 716 at the lowest end to adapt to the adjustment of weight from light to heavy.

[0041] The outer wall of the trigger rod 71 is provided with a stop bar 715 along its own circumference. The stop bar 715 and the limiting ridge 721 are aligned axially along the trigger rod 71. When the rotating trigger ring 72 drives the separation plate to separate the second steel ball 75 from the limiting recess 716, because the stop bar 715 and the limiting ridge 721 are aligned axially along the trigger rod 71, the wedge block 73 will synchronously drive the trigger rod 71 to move upward under the squeezing force of the sliding block 63, and the limiting ridge 721 can stop and limit the stop bar 715, so that the trigger rod 71 can rely on its own gravity to vertically descend after resisting and resetting, ensuring the stability of the automatic reset of the trigger rod 71 in the trigger ring 72.

[0042] As attached Figure 5 and attached Figure 7 As shown, a fine-tuning mechanism 8 is provided in the pressure block 41 along a direction perpendicular to the sliding direction of the slide rod 42. The fine-tuning mechanism 8 includes a fixing nut 81, an adjusting rod 82 and a transmission block 83. The fixing nut 81 and the adjusting rod 82 are coaxial with the movable groove 411. The fixing nut 81 is fixedly connected to the end of the movable groove 411 in the vertical direction. The adjusting rod 82 is threadedly connected to the fixing nut 81. The wedge block 73 slides axially along the movable groove 411 at the bottom end of the trigger rod 71, and the end of the adjusting rod 82 facing the movable groove 411 is provided with a screw thread connected to the wedge block 73. The transmission block 83 is in contact with each other, and the other end of the adjustment rod 82 passes through the outside of the pressure block 41. The horizontal cross-sections of the sliding block 63 and the transmission block 83 are smaller than the horizontal cross-sections of the movable groove 411, so that the sliding block 63 and the transmission block 83 can slide flexibly in the movable groove 411 to avoid jamming due to excessive size. The adjustment rod 82 can move axially by rotation, and the transmission block 83 transmits the movement of the adjustment rod 82 to the wedge block 73, thereby further accurately adjusting the pressure applied by the first spring 61 to the first steel ball 62.

[0043] When automatic adjustment cannot meet precise requirements, the adjusting rod 82 can be rotated to move the adjusting rod 82 in the fixing nut 81. The adjusting rod 82 pushes the wedge block 73 through the transmission block 83, thereby changing the position of the sliding block 63, and finally fine-tuning the degree of clamping of the first steel ball 62 on the notch 421 of the sliding rod 42, further improving the adaptability of the device to customers of different weights and ensuring the stability of the support more accurately.

[0044] The implementation principle of this embodiment is: The two support plates 1 are opened in opposite directions, the support frame 3 is unfolded, the physiotherapy bed is placed on the horizontal ground, and the trigger ring 72 is pulled up along the axial direction of the trigger rod 71 by rotating the rod 724. When the trigger ring 72 rises to the top, the connecting ring 722 on the outer wall of the bottom of the trigger ring 72 will abut against the inner wall of the upper surface of the pressure block 41, and then the trigger ring 72 is rotated by rotating the rod 724 to make the limiting ridge 721 slide along the outer wall of the trigger rod 71 and between the two relatively parallel limiting slides 714, so that the trigger ring 72 and the trigger rod 71 are locked in the vertical direction; the chiropractor drives the lifting block by rotating the connecting rod 51 52 rotates, and the lifting block 52 synchronously drives the corresponding part of the support bed body 2 and the slide bar 42 to lift. The customer lies on the corresponding support bed body 2, and the weight of the corresponding part of the customer is transmitted to the trigger rod 71 through the trigger ring 72. The trigger rod 71 presses down the wedge block 73, pushing the slide block 63 to compress the first spring 61. The first steel ball 62 dynamically adjusts the pressing force on the notch 421 of the slide bar 42 according to the pressure to ensure that the supporting force matches the customer's weight. During the downward movement of the trigger rod 71, the second steel ball 75 is sequentially stuck in the limit notches 716 of different depths to achieve segmented locking, ensuring that the trigger rod 71 continuously and stably applies pressure; After the client lies on the corresponding support bed 2 at the corresponding part, the client uses his or her own body weight to adjust the pressure of the first steel ball 62 on the notch 421 of the slide bar 42. After the adjustment is completed, the chiropractor drives the trigger ring 72 to rotate by rotating the rod 724. After the rotation, the trigger ring 72 falls into the pressure block 41. When the trigger ring 72 falls into the pressure block 41, the chiropractor can continue to treat the client under this pressure. At the same time, when it is necessary to change to a customer of a different weight, the chiropractor only needs to rotate the trigger ring 72 again by rotating the rod 724. The groove wall of the separation groove 723 will press the second steel ball 75, forcing the second steel ball 75 to no longer abut against the corresponding limiting recess 716. At this time, the trigger rod 71 will be reset under the elastic potential energy of the first spring 61. After the reset is completed, the trigger ring 72 is rotated by rotating the rod 724 so that the second steel ball 75 can abut against the limiting recess 716 at the bottom end of the trigger rod 71, and the above operation is repeated subsequently.
