DETAILED DESCRIPTION

[0027] The embodiments of the present application will be described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application. All other examples obtained by those skilled in the art without making creative efforts fall within the scope of the present application.

[0028] In combination with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a traction bed, comprising a bed frame 1, the bottom of the bed frame 1 is connected with a scissor lifting seat 7, one end of the scissor lifting seat 7 is provided with a stand 8, the bed frame 1 is provided with a main plate 2 and two adjustable angle traction leg plates 3, the inside of the two sides of the main plate 2 is provided with an adjusting disc 4 capable of rotating and adjusting the angle of the traction leg plate 3 outwardly unfolded, the adjusting disc 4 is provided with a toothed positioning plate 41, the two sides of the bed frame 1 are further provided with a locking mechanism 5, the locking mechanism 5 is provided with a V-shaped positioning block 51 matched with the tooth groove of the toothed positioning plate 41, when the adjusting disc 4 is rotated, the V-shaped positioning block 51 can be embedded into different tooth grooves of the toothed positioning plate 41.

[0029] The traction bed provides precise and adjustable spinal traction treatment experience for users. The traction bed mainly comprises a bed frame 1, and the bed frame 1 is designed to be stable and easy to operate. The bottom of the bed frame 1 is connected with a scissor lifting seat 7, which allows users to easily adjust the height of the bed surface by operating the scissor lifting seat 7 to adapt to patients of different heights or treatment needs, and also facilitates the operation and adjustment of medical personnel.

[0030] One end of the scissor lifting seat 7 is provided with a stand 8, which not only enhances the overall stability of the bed body, but also provides a reliable mounting point for other accessories. The bed frame 1 is installed with a main plate 2, which is the core component of the traction system and bears the operation of the entire traction mechanism. Above the main plate 2, two adjustable angle traction leg plates 3 are designed, which can provide personalized traction treatment for patients according to different treatment needs, effectively relieve spinal pressure and promote recovery.

[0031] The inside of the two sides of the main plate 2 is provided with adjusting discs 4, which are the key components for adjusting the angle of the traction leg 3. The adjusting disc 4 is designed to be rotatable, and users can easily change the included angle between the traction leg 3 and the bed frame 1 by rotating the adjusting disc 4, so as to adapt to the traction needs of different patients.

[0032] The adjusting disc 4 is provided with a toothed positioning plate 41, which greatly improves the accuracy and stability of angle adjustment. The tooth grooves on the toothed positioning plate 41 are evenly and finely distributed, ensuring that every small angle change during the adjustment process can be accurately captured and fixed.

[0033] In order to realize reliable locking of the angle of the traction leg plate 3, the two sides of the bed frame 1 are also carefully provided with locking mechanisms 5. These locking mechanisms 5 are compact in structure and easy to operate, and their core component is a V-shaped positioning block 51. The shape of the V-shaped positioning block 51 perfectly matches the tooth grooves of the toothed positioning plate 41, and when the adjusting disc 4 is rotated to the required angle, the V-shaped positioning block 51 can be embedded into the corresponding tooth groove of the toothed positioning plate 41, thereby realizing firm locking of the outward unfolding angle between the traction leg plate 3 and the bed frame 1.

[0034] The manual traction bed also has the advantages of simple operation, flexible adjustment, strong stability, etc. Users only need to rotate and lock simply, and the angle adjustment and locking of the traction leg plate 3 can be quickly completed, which greatly improves the efficiency and comfort of traction treatment. At the same time, the structure design of the traction bed also fully considers the safety and comfort of the patient, ensuring the safety and treatment effect during traction. The manual traction bed has wide application prospect and important clinical value in the medical field due to its exquisite structure design and practical function characteristics.

[0035] In combination with Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , the adjusting disc 4 includes a fixed frame 42 arranged inside the bed frame 1, a rotating disc 43 sleeved on the fixed frame 42, and a rotating bearing 44 installed between the rotating disc 43 and the fixed frame 42. The rotating disc 43 and the toothed positioning plate 41 are arranged on one side of the bottom of the traction leg 3, and the rotating disc 43 is coaxially connected with the toothed positioning plate 41.

[0036] Specifically, the adjusting disc 4 is mainly composed of a fixed frame 42 arranged inside the bed frame 1. This fixed frame 42 not only plays a supporting and fixing role, but also provides a stable foundation for subsequent rotation adjustment. On the fixed frame 42, a rotating disc 43 is sleeved. The design of the rotating disc 43 allows users to adjust the angle of the traction leg plate 3 through simple rotation, thereby meeting different treatment needs. In order to ensure that the rotating disc 43 can rotate smoothly, a high-quality rotating bearing 44 is installed between the rotating disc 43 and the fixed frame 42. This rotating bearing 44 not only reduces friction and resistance during rotation, but also improves the durability and reliability of the entire adjustment system.

[0037] The rotating disc 43 and the toothed positioning plate 41 are arranged on one side of the bottom of the traction leg plate 3, which not only makes the adjustment process more intuitive and convenient, but also ensures that the traction leg 3 can maintain stable support when adjusting the angle. The coaxial connection between the rotating disc 43 and the toothed positioning plate 41 not only enhances the connection strength between the two, but also ensures that the rotating disc 43 can drive the toothed positioning plate 41 to rotate synchronously when rotating, thereby achieving precise adjustment of the angle of the traction leg plate 3.

[0038] In addition, the design of the tooth groove on the toothed positioning plate 41 is also a highlight of the adjusting disc 4. These tooth grooves not only match the V-shaped positioning block 51 on the locking mechanism 5, but also provide clear positioning points and resistance feedback during rotation, allowing users to intuitively feel the change in the angle of the traction leg 3 and easily lock the traction leg 3 at the desired angle.

[0039] In combination with Figure 4 ,Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown in

[0040] In combination with Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in

[0041] Further, the locking mechanism 5 provides users with a safe and reliable locking experience. On the fixed frame 42 of the adjustment disc 4, a fixed block 52 is movably arranged. This fixed block 52 not only provides stable support for the locking mechanism 5, but also realizes precise control and guidance of the four-square positioning rod 53 through its internal structure design.

[0042] The fixed block 52 movably connects a four-square positioning rod 53, which is the core component in the locking mechanism 5. The four-square positioning rod 53 is uniquely designed, with a regular square shape that not only increases the contact area with the fixed block 52, improving the stability and smoothness of sliding, but also avoids the risk of turning under stress. A compression spring is arranged between the top of the four-square positioning rod 53 and the fixed block 52. This compression spring serves as a buffer and reset. When the user operates the pressing handle 54, the compression spring will be compressed and store energy. When the pressing handle 54 is released, the spring will release energy and push the four-square positioning rod 53 back to its original position, thus realizing precise locking of the V-shaped positioning block 51.

[0043] One end of the four-square positioning rod 53 is provided with a pressing handle 54. The user only needs to hold the pressing handle 54 and press it down slightly, which can make the four-square positioning rod 53 slide in the square slot 521 of the fixed block 52, and then drive the V-shaped positioning block 51 to move, realizing the unlocking or locking of the angle of the traction leg 3.

[0044] The square sliding groove 521 is an important design on the fixed block 52, which is fully matched with the shape and size of the four-square positioning rod 53. It not only ensures the stability and accuracy of the four-square positioning rod 53 during sliding, but also avoids the risk of deviation or jamming under stress. The bottom of the square sliding groove 521 is also provided with a certain inclination angle. This design enables the four-square positioning rod 53 to gradually approach or move away from the fixed position of the V-shaped positioning block 51 during sliding, thereby achieving fine adjustment of the angle of the traction leg 3.

[0045] In actual use, when the user needs to adjust the angle of the traction leg 3, he only needs to hold the pressing handle 54 lightly and press it down, so that the four-square positioning rod 53 slides in the square sliding groove 521, thereby driving the V-shaped positioning block 51 to come out of the tooth groove of the tooth-shaped positioning plate 41. Then rotate the adjusting disc 4 to adjust the angle of the traction leg 3. When rotated to the desired position, release the pressing handle 54, and the compression spring will push the four-square positioning rod 53 back to its original position, so that the V-shaped positioning block 51 re-embeds into the tooth groove of the tooth-shaped positioning plate 41, thereby achieving precise locking of the angle of the traction leg 3.

[0046] In combination with Figure 2 , Figure 3 , Figure 4 and Figure 6 , it further includes an adjusting mechanism 6 for adjusting the movement of the main plate 2 on the bed frame 1.

[0047] In combination with Figure 2 , Figure 3 , Figure 5 and Figure 6 , the adjusting mechanism 6 includes a threaded sleeve 61 provided on the bed frame 1, a threaded rod 62 screw-connected inside the threaded sleeve 61, and a hand wheel adjuster 63 connected to one end of the threaded rod 62, which is fixedly installed on the bottom of the main plate 2 by bolts.

[0048] In combination with Figure 3 , Figure 4 , Figure 5 and Figure 6 , the bed frame 1 is provided with a sliding rail 11, and the bottom of the main plate 2 is provided with a sliding block 21 matching the sliding rail 11.

[0049] Further, in the design of the manual traction bed, in order to further enhance its flexibility and adaptability, an adjusting mechanism 6 for adjusting the movement of the main plate 2 on the bed frame 1 is added. Not only does it allow the user to easily adjust the position of the main plate 2 as needed, but it also ensures the stability and comfort during traction treatment.

[0050] The adjustment mechanism 6 is mainly composed of a threaded sleeve 61, a threaded rod 62, and a hand wheel adjuster 63. The threaded sleeve 61 is installed in the appropriate position of the bed frame 1, and its interior is designed with threads for threaded connection with the threaded rod 62. Not only does it ensure the accuracy and stability of the adjustment, but it also makes the adjustment process smoother and more labor-saving.

[0051] One end of the threaded rod 62 is connected to the threaded sleeve 61, and by rotating the threaded rod 62, movement inside the threaded sleeve 61 can be achieved. This lifting movement is the key to adjusting the position of the main board 2. The other end of the threaded rod 62 is connected to the hand wheel adjuster 63, which is installed on the bottom of the main board 2 by bolts. The user only needs to gently turn the hand wheel adjuster 63 to drive the threaded rod 62 to rotate and move in the threaded sleeve 61, thereby achieving the movement of the main board 2.

[0052] In order to further enhance the stability and accuracy of the movement of the main board 2, the bed frame 1 is also specially provided with a slide rail 11. The design of the slide rail 11 fully considers the movement trajectory and load requirements of the main board 2, ensuring the stability and smoothness of the main board 2 during movement. At the same time, the bottom of the main board 2 is also correspondingly provided with a sliding block 21 that perfectly matches the slide rail 11. The sliding block 21 not only can freely slide on the slide rail 11, but also can effectively bear the weight of the main board 2 and its upper components, thereby ensuring the reliability and safety of the entire adjustment process.

[0053] In actual use, the user only needs to adjust the position of the main board 2 by turning the hand wheel adjuster 63 according to the needs of traction therapy. With the movement of the threaded rod 62 in the threaded sleeve 61, the main board 2 will move smoothly along the slide rail 11 until it reaches the desired position. Not only is it simple and easy to use, but it also ensures the accuracy and stability of the adjustment, providing users with a more comfortable and efficient traction therapy experience.

[0054] The design of the adjustment mechanism 6 also fully considers the convenience and safety of user operation. The surface of the hand wheel adjuster 63 is treated with anti-slip, making it easy for users to hold and turn during adjustment. At the same time, components such as the threaded sleeve 61 and the threaded rod 62 are made of high-strength, corrosion-resistant materials, ensuring the durability and reliability of the entire adjustment mechanism.

[0055] The addition of the adjustment mechanism 6 makes the design of the manual traction bed more perfect and the function more comprehensive. Users not only can easily adjust the position of the main board 2 according to their needs, but also can enjoy a more stable and comfortable experience during traction therapy.

[0056] In combination with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, both the main board 2 and the traction leg board 3 are provided with sponge soft pads 10.

[0057] In combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the outer sides of the two traction leg boards 3 are provided with handles 31, and the inner sides of the two traction legs 3 are oppositely provided with positioning blocks 32.

[0058] Specifically, in the design of the manual traction bed, in order to further improve the comfort and use experience of users, sponge soft pads 10 are provided on the main board 2 and the traction leg board 3. Not only does it provide users with softer and more comfortable support, but it also effectively relieves the pressure and discomfort that may occur during traction.

[0059] The sponge soft pad 10 is made of high-quality sponge material, which has excellent elasticity and resilience. When the user lies on the main board 2 or leans his body on the traction leg board 3, the sponge soft pad 10 can quickly adapt to the body's contour and weight distribution, thereby providing uniform support force. Not only helps to maintain the balance and stability of the body, but also effectively disperses the pressure, reduces the fatigue and discomfort that may be caused by long-term traction. The surface of the sponge soft pad 10 has also undergone a special treatment process, making it have better air permeability and moisture absorption. Even in the process of long-term use, it can keep the surface dry and comfortable, avoiding the discomfort caused by dampness and heat.

[0060] In the design of the traction leg board 3, the convenience and comfort of the user are considered. In order to facilitate the user to adjust the angle and position of the traction leg board 3, the outer sides of the two traction leg boards 3 are provided with handles 31. The design of the handle 31 is simple and practical, the user only needs to hold the handle 31 lightly and apply appropriate force, so as to easily move or rotate the traction leg board 3, so as to realize the accurate adjustment of the traction angle and position.

[0061] In order to enhance the stability and safety of the traction leg board 3, the inner sides of the two traction leg boards 3 are oppositely provided with positioning blocks 32. The positioning block 32 is made of high-strength and wear-resistant material, which can effectively prevent the traction leg board 3 from shifting or shaking during traction. Not only improves the accuracy and stability of traction therapy, but also provides users with a more secure and reliable traction experience.

[0062] In actual use, users can easily adjust the angle and position of the traction leg board 3 through the handle 31 according to their own needs and comfort. At the same time, the soft support and air permeability of the sponge soft pad 10, and the stabilizing effect of the positioning block 32, together provide users with a comfortable, safe and efficient traction therapy environment.

[0063] The sponge soft pad 10 arranged on the main plate 2 and the traction leg plate 3, the handle 31 on the outer side of the traction leg plate 3 and the positioning block 32 on the inner side and the like design not only improve the comfort and convenience of the manual traction bed, but also ensure the accuracy and safety of the traction treatment.

[0064] In combination Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the top of the column 8 is connected with a traction frame 9, and the traction frame 9 is provided with a plurality of traction hooks 91.

[0065] Specifically, the column 8 is an important component of the traction bed, which not only bears the structural stability of the whole bed body, but also undertakes the key task of connecting the traction system. At the top of the column 8, a traction frame 9 is designed, which not only enhances the functionality of the traction bed, but also provides necessary support points for traction treatment.

[0066] The structural design of the traction frame 9 fully considers practicability and durability, and adopts a solid material to ensure that it can withstand sufficient traction force and impact force during use. On the surface of the traction frame 9, a plurality of traction hooks 91 are arranged, which are not only sufficient in quantity and reasonable in layout, but also adopt an easy-to-connect and release design, so that medical staff can quickly and accurately connect the traction belt or other traction devices to the traction hooks 91, thereby effectively performing traction treatment on patients.

[0067] The design of the traction hooks 91 also fully considers safety and ease of use. They are made of high-strength material and can withstand various force changes during treatment to ensure safety. At the same time, the shape and size of the traction hooks 91 are carefully calculated, so that the traction belt or other traction devices can be stably hung on the traction hooks 91 and are not easy to slip or loosen, thereby improving the stability and reliability of the treatment.

[0068] In addition, the height and angle of the traction frame 9 can also be adjusted according to treatment needs. Through the adjusting mechanism on the column 8, medical staff can easily change the height and inclination angle of the traction frame 9 to adapt to patients of different heights and treatment sites, thereby providing more personalized traction treatment programs.

[0069] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
