Description

Technical Field

[0001] This utility model relates to the field of traction device technology, specifically a traction device for a hospital bed. Background Technology

[0002] A traction device is a device or mechanism used to move or pull an object. It moves an object by applying traction or pulling force. Traction devices are used in transportation, construction engineering, and the medical field, among others. In the medical field, hospital beds, also known as medical beds, nursing beds, patient beds, or rehabilitation beds, are special beds used by patients during treatment, rehabilitation, and recuperation. Traction devices are used on these beds to perform traction exercises on specific parts of the body for therapeutic purposes. With advancements in technology and industrial development, the application of traction devices in various fields is becoming increasingly widespread.

[0003] Common traction devices used in hospital beds typically consist of a traction mechanism, a control system, and other auxiliary components, including a catheterization mechanism. The traction mechanism includes a traction rod, a traction rope, and a pulley system. The traction rod is the primary component for transmitting traction force. The traction rope connects the traction rod to the patient and transmits the traction force. The pulley system is used to change the direction and magnitude of the traction force. The control system controls the starting, stopping, and adjustment of the traction force. Other auxiliary components include adjustment devices, safety devices, accessories, and fittings.

[0004] Traditional traction devices for hospital beds connect the bed and the device via cables, which are then used to apply traction to the patient's injured area. However, these cables are prone to breakage and detachment after prolonged use, compromising the stability of the connection between the traction device and the bed. To address this issue, some traction devices for hospital beds use bolts to connect the bed and the device. Bolted connections offer high stability, ensuring a secure connection between the bed and the traction device. They can also withstand significant traction and impact forces, making them suitable for applications requiring high-intensity traction. However, this method requires precise hole alignment and bolt tightening, making installation relatively complex and hindering disassembly. Therefore, a new traction device for hospital beds is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides a traction device for a hospital bed to solve the above-mentioned technical problems that not only increase the difficulty of installation, but also make disassembly operations inconvenient.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a traction device for a hospital bed, comprising:

[0009] The main body of the hospital bed, and the side connecting blocks set on both sides of the main body of the hospital bed, with connecting holes evenly opened on the top of the side connecting blocks;

[0010] The main body of the device is located on the top of the side connecting block, and the main body of the device also includes a connecting seat and an annular hanging plate. A rotating handle is added to the bottom center of the connecting seat, and positioning screws are connected to both sides of the rotating handle. Positioning screw holes are opened around the bottom of the connecting seat.

[0011] A rotating shaft is located within the inner cavity of the connecting seat, and an arc-shaped pressure plate is connected to the surface of the rotating shaft. Arc-shaped side plates are added to both sides of the inner cavity of the connecting seat, and a limiting cone rod is connected to the outer side of the arc-shaped side plate. A return spring is added between the arc-shaped side plate and the limiting cone rod. When installing the main body of the device onto the bed body, the connecting seat is first inserted into the connecting hole of the side connecting block. Then, the rotating handle is rotated to drive the rotating shaft, and the arc-shaped pressure plate presses against the arc-shaped side plate, causing the outer end of the limiting cone rod to move to the outside of the connecting seat and connect with the inner wall of the side connecting block. The positioning screw is then rotated on the rotating handle to connect with the corresponding positioning screw hole. This not only reduces the difficulty of installation but also facilitates disassembly. Furthermore, after the rotating handle has rotated, the positioning screw and positioning screw hole ensure the stability of the connection between the connecting seat and the side connecting block. Simultaneously, the main body of the device can be moved to different positions in the connecting holes on the side connecting block depending on the situation.

[0012] Preferably, the bottom of the main body of the hospital bed is provided with storage slots on both sides, and a rotating shaft is rotatably connected to the center of the inner cavity of the storage slot. The rotating shaft can rotate within the storage slot.

[0013] Preferably, a drive motor is installed on the outer side of the main body of the hospital bed, and the drive motor is coaxially connected to a rotating shaft, which is connected to a side connecting block. The drive motor drives the rotating shaft to rotate on the main body of the hospital bed, and the rotating shaft drives the side connecting block to rotate into the storage slot. Thus, when the main body of the device is not in use, it not only facilitates the storage of the connecting structure and saves space, but also does not affect the daily use of the main body of the hospital bed.

[0014] Preferably, the connecting seat corresponds to the connecting hole, and the end of the limiting cone rod extends outward through the interior of the connecting seat and is inserted into the inner wall of the connecting hole for connection. The connecting seat can be inserted into the interior of the connecting hole for connection, and the outer end of the limiting cone rod can be inserted into the connecting seat for connection.

[0015] Preferably, the end of the return spring is tightly fitted to the inner wall of the connecting seat and the outer side of the arc-shaped side plate, respectively. When the arc-shaped pressure plate separates from the arc-shaped side plate, the return spring causes the arc-shaped side plate and the limiting cone rod to return to their original positions, thereby facilitating separation and disassembly.

[0016] Preferably, an adjusting screw is installed on the top of the connecting seat, and a fixed plate is connected to the telescopic end of the adjusting screw. An adjusting screw is also installed on the fixed plate, and the annular hanging plate is connected to the telescopic end of the adjusting screw. The adjusting screw on the connecting seat can adjust the height of the fixed plate, while the adjusting screw on the fixed plate can adjust the length of the annular hanging plate, thereby allowing the annular hanging plate to be used on different parts of the patient.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a traction device for a hospital bed, which has the following beneficial effects:

[0019] This traction device for hospital beds, when installed on the bed frame, first inserts the connecting seat into the connecting hole of the side connecting block. Then, rotating the rotating handle drives the rotating shaft, and the arc-shaped pressure plate presses against the arc-shaped side plate, causing the outer end of the limiting cone rod to move to the outside of the connecting seat and connect with the inner wall of the side connecting block. The positioning screw is then rotated on the rotating handle to connect with the corresponding positioning screw hole. This not only reduces the difficulty of installation and facilitates disassembly, but also ensures the stability of the connection between the connecting seat and the side connecting block after the rotating handle is rotated, through the positioning screw and positioning screw hole. Simultaneously, the device body can be moved to different positions on the side connecting block according to different situations. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution: a traction device for a hospital bed, comprising: (See attached diagram) Figure 1 The bed body 1, and the side connecting blocks 6 set on both sides of the bed body 1, with connecting holes 7 evenly opened on the top of the side connecting blocks 6;

[0027] Please see Figure 3 The main body 2 of the device is located on the top of the side connecting block 6. The main body 2 of the device also includes a connecting seat 8 and an annular hanging plate 12. A rotating handle 13 is added to the bottom center of the connecting seat 8, and positioning screws 14 are connected to both sides of the rotating handle 13. Positioning screw holes 15 are opened around the bottom of the connecting seat 8.

[0028] Please see Figure 4 A rotating shaft 16 is located within the inner cavity of the connecting seat 8, and an arc-shaped pressure plate 17 is connected to the surface of the rotating shaft 16. Arc-shaped side plates 18 are added to both sides of the inner cavity of the connecting seat 8, and a limiting cone rod 19 is connected to the outer side of the arc-shaped side plate 18. A return spring 20 is added between the arc-shaped side plate 18 and the limiting cone rod 19. When the main body 2 of the device is installed on the main body 1 of the hospital bed, the connecting seat 8 is first inserted into the connecting hole 7 of the side connecting block 6. Then, the rotating handle 13 is rotated to drive the rotating shaft 16, and the arc-shaped pressure plate 17 presses the arc-shaped side plate 18, so that the outer end of the limiting cone rod 19 moves to the outside of the connecting seat 8 and is inserted between the outer wall of the side connecting block 6. The positioning screw 14 is rotated on the rotating handle 13 to connect the positioning screw 14 with the corresponding positioning screw hole 15. On the one hand, it not only reduces the difficulty of installation but also facilitates disassembly; on the other hand, after the rotating handle 13 has rotated, the stability of the connection between the connecting seat 8 and the side connecting block 6 can be ensured by the positioning screw 14 and the positioning screw hole 15. At the same time, the main body 2 of the device can be moved to the connecting hole 7 at different positions on the side connecting block 6 according to different situations.

[0029] Please see Figure 2 The bottom of the main body 1 of the hospital bed has storage slots 3 on both sides, and a rotating shaft 4 is rotatably connected to the center of the inner cavity of the storage slot 3. The rotating shaft 4 can rotate within the storage slot 3. A drive motor 5 is installed on the outside of the main body 1 of the hospital bed, and the drive motor 5 is coaxially connected to the rotating shaft 4. The rotating shaft 4 is connected to the side connecting block 6. The drive motor 5 drives the rotating shaft 4 to rotate on the main body 1 of the hospital bed, and the rotating shaft 4 drives the side connecting block 6 to rotate into the storage slot 3. Thus, when the main body 2 of the device is not in use, it is not only convenient to store the connecting structure, saving space, but also does not affect the daily use of the main body 1 of the hospital bed.

[0030] Please see Figure 4 The connecting seat 8 corresponds to the connecting hole 7, and the end of the limiting cone rod 19 extends outward through the interior of the connecting seat 8 and is inserted into the inner wall of the connecting hole 7. The connecting seat 8 can be inserted into the interior of the connecting hole 7 for connection, and the outer end of the limiting cone rod 19 can be inserted into the connecting seat 8. The end of the return spring 20 is tightly fitted to the inner wall of the connecting seat 8 and the outer side of the arc-shaped side plate 18. When the arc-shaped pressure plate 17 separates from the arc-shaped side plate 18, the arc-shaped side plate 18 and the limiting cone rod 19 are reset under the action of the return spring 20, thereby facilitating separation and disassembly.

[0031] Please see Figure 3 An adjusting screw 9 is installed on the top of the connecting seat 8, and the telescopic end of the adjusting screw 9 is connected to a fixing plate 10. An adjusting screw 11 is installed on the fixing plate 10, and the annular hanging plate 12 is connected to the telescopic end of the adjusting screw 11. The adjusting screw 9 on the connecting seat 8 can adjust the height of the fixing plate 10, while the adjusting screw 11 on the fixing plate 10 can adjust the length of the annular hanging plate 12, thereby allowing the annular hanging plate 12 to be used with different parts of the patient.

[0032] This solution involves installing the main body 2 of the device onto the main body 1 of the hospital bed. First, the connecting seat 8 is inserted into the connecting hole 7 of the side connecting block 6. Then, the rotating handle 13 is rotated to drive the rotating shaft 16, and the arc-shaped pressure plate 17 presses against the arc-shaped side plate 18, causing the outer end of the limiting cone rod 19 to move to the outside of the connecting seat 8 and insert between it and the inner wall of the side connecting block 6. The positioning screw 14 is rotated on the rotating handle 13 to connect with the corresponding positioning screw hole 15. When the arc-shaped pressure plate 17 separates from the arc-shaped side plate 18, the arc-shaped side plate 18 and the limiting cone rod 19 are reset under the action of the return spring 20. The drive motor 5 drives the rotating shaft 4 to rotate on the main body 1 of the hospital bed, and the rotating shaft 4 drives the side connecting block 6 to rotate into the storage groove 3. The adjusting screw 9 on the connecting seat 8 can adjust the height of the fixing plate 10, while the adjusting screw 11 on the fixing plate 10 can adjust the length of the annular hanging plate 12.
