Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a hospital bed with an automatically retractable rocker. Background Art

[0002] In the early medical environment, the design of hospital beds was relatively simple and the functions were relatively basic, mainly meeting the basic rest needs of patients. However, with the rapid development of medical technology and the continuous improvement of medical needs, the design of hospital beds has gradually become more complex and multifunctional. Medical staff need to frequently operate the hospital bed to adjust the patient's position, perform medical operations, etc., which increases their workload. Therefore, improving the convenience and automation level of hospital beds has become an important direction for the development of medical technology. Initially, the design of hospital beds focused on providing a comfortable rest environment, including basic functions such as height adjustment and tilt angle adjustment. With the development of mechanical technology, hospital beds began to be equipped with some mechanical auxiliary devices, such as manual rockers, for adjusting different parts of the bed. These improvements have improved the convenience of hospital beds to a certain extent, but manual operation is still required. With the development of electric technology, hospital beds have gradually become electrified. Electric hospital beds can realize automatic lifting, tilting and other functions of hospital beds through motors and transmission devices, reducing the manual operation of medical staff. In recent years, with the rapid development of intelligent technology, the design of hospital beds has also been further intelligentized and automated. The bed with automatic rocker recovery is the product of this stage. Through the comprehensive application of technologies such as sensors, control systems and actuators, the bed can automatically identify and respond to the operating instructions of medical staff, realize the automatic retraction and deployment of the joystick, and greatly improve the convenience and safety of the bed's use.

[0003] In a rocker structure for a hospital bed with patent number CN202221316258.9, the compression spring therein is deformed by pulling the telescopic sliding rocker outward, and after adjustment, the telescopic sliding rocker is retracted by the compression spring. After the telescopic sliding rocker is pulled out, it is obvious that there is no mechanism for locking the spring in the patent, which means that in the process of rotating the foldable handle, the arm not only has to rotate, but also has to keep pulling the telescopic sliding rocker outward to prevent it from being brought back by the compression spring. Secondly, after the compression spring is reset, only the telescopic sliding rocker is reset, and the foldable handle is not reset. On some narrower sides of the hospital bed, the foldable handle will still extend outward, thereby tripping pedestrians. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides a hospital bed with an automatically retractable rocker arm, which has the advantages of a locking spring to offset the spring restoring force when the rocker arm is used, which is more labor-saving, further retracts the handle, prevents the handle from tripping medical staff, and reduces the workload of ward management. It solves the problem that after the telescopic sliding rocker arm is pulled out, it is obvious that there is no locking spring mechanism in the above patent, which results in that in the process of rotating the foldable handle, the arm not only has to make a rotating movement, but also has to keep pulling the telescopic sliding rocker arm outward to prevent it from being brought back by the compression spring. Secondly, after the compression spring is reset, it only resets the telescopic sliding rocker arm, and does not reset the foldable handle. On some narrower sides of the hospital bed, the foldable handle will still extend outward, thereby tripping pedestrians.

[0006] (II) Technical solution

[0007] In order to achieve the purpose of locking the spring to offset the spring restoring force when the rocker is used, saving more effort, further retracting the handle, preventing the handle from tripping medical staff, and reducing the workload of ward management, the utility model provides the following technical solutions: a hospital bed with automatic rocker recovery, comprising a bed frame, a movable bed board, a connecting frame and a threaded rod, the bottom of the movable bed board is provided with a connecting frame, one end of the connecting frame is assembled with the threaded rod, one end of the threaded rod is fixedly connected with a rocker sleeve, the rocker sleeve is provided with a slide groove, the end of the slide groove away from the threaded rod is provided with a side groove perpendicular to the slide groove, a rocker is slidably arranged in the rocker sleeve, a pin is provided at the near threaded rod end of the rocker, the pin is assembled in the slide groove, a spring is provided between the rocker sleeve and the rocker, a connecting rod is provided at the far threaded rod end of the rocker, and a handle is provided on the connecting rod.

[0008] Preferably, mounting columns are respectively provided on both sides of the slide groove close to the side groove.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a hospital bed with an automatically retractable rocker, which has the following features:

[0017] Beneficial effects:

[0018] The hospital bed with automatic rocker recovery is used by the cooperation of a movable bed board, a threaded rod, a rocker sleeve, a rocker and a handle. When the angle of the movable bed board needs to be adjusted, the rocker is first pulled outward from the rocker sleeve until the pin on the rocker is pulled to a position flush with the side groove, and then the handle is turned out, and the rocker begins to rotate. When the rocker begins to rotate, since the pin is located at a position flush with the side groove, as the rocker rotates, the pin will be stuck in the side groove, thereby completing the locking of spring 1, preventing the user from having to overcome the rebound force of spring 1 when rotating the rocker due to the rebound force, which makes the user more laborious. The rotation of the rocker drives the rotation of the rocker sleeve, and further drives the rotation of the threaded rod integrated with the rocker sleeve, thereby making the connection move, and finally adjusting the angle of the movable bed board. After the movable bed board is adjusted to the appropriate position, the rocker is rotated back a certain distance so that the pin is located in the slide groove again. At this time, the handle is released. Since there is no locking of the side groove, the spring 1 will reset the rocker when it is reset. At the same time, the spring 2 located in the wedge groove will also tighten the handle on the connecting rod when it is reset. During the rocker reset process, due to the blocking effect of the rubber column, the user can have enough time to pull out the operating hand to prevent the user from being injured by retracting too quickly. In this way, the locking spring offsets the spring restoring force when using the rocker, which is more labor-saving, and the handle can be further retracted to prevent the handle from tripping medical staff and reducing the workload of ward management.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 A hospital bed with an automatic rocker recovery includes a bed frame 1, a movable bed board 3, a connecting frame 4 and a threaded rod 2. The bottom of the movable bed board 3 is provided with a connecting frame 4, and one end of the connecting frame 4 is assembled with the threaded rod 2. The bed frame 1 is used as the main structure of the hospital bed to support the entire hospital bed and ensure stability and load-bearing capacity. The movable bed board 3 is used for patients to lie down, and the different needs of patients can be met by adjusting the angle. The connecting frame 4 arranged at the bottom enables the movable bed board 3 to be assembled with the threaded rod 2, so that the angle can be adjusted by rotating the threaded rod 2. This structure is a common structure and is not described here. The connecting frame 4 is a key component that connects the movable bed board 3 and the threaded rod 2, ensuring a stable connection between the two, so that the movable bed board 3 can be driven to adjust the angle when the threaded rod 2 is rotated. The threaded rod 2 can drive the connecting frame 4 and the movable bed board 3 to perform lifting and lowering movements by rotating, thereby adjusting the angle of the movable bed board 3. One end of the connecting frame 4 is fixedly connected to the rocker sleeve 5 to ensure that the threaded rod 2 can be driven to rotate when the rocker 6 is rotated.

[0028] One end of the threaded rod 2 is fixedly connected to a rocker sleeve 5, on which a slide groove 51 is provided, and one end of the slide groove 51 away from the threaded rod 2 is provided with a side groove 52 perpendicular to the slide groove 51. The rocker sleeve 5 is fixedly connected to one end of the threaded rod 2, and is provided with a slide groove 51 and a side groove 52 inside for sliding and locking the rocker 6. The slide groove 51 allows the rocker 6 to slide therein, while the side groove 52 is used to lock the pin 61 at a specific position to prevent the rocker 6 from moving due to the rebound force of the spring when rotating. The slide groove 51 is on the rocker sleeve 5, allowing the pin 61 on the rocker 6 to slide when the rocker 6 is pulled out until the pin 61 is aligned with the side groove 52. The side groove 52 is perpendicular to the slide groove 51. When the pin 61 is aligned with it, the pin 61 can be inserted into the side groove 52 by rotating the rocker 6, thereby locking the rocker sleeve 5 and the rocker 6 to prevent the rebound force of the spring from affecting the operation. A rocker 6 is slidably arranged in the rocker sleeve 5. The user drives the threaded rod 2 to rotate by operating the rocker 6, thereby adjusting the angle of the movable bed board 3. The pin 61 on the rocker 6 is assembled in the slide groove 51 to achieve connection and locking with the rocker sleeve 5. A pin 61 is arranged at the end of the near threaded rod 2 of the rocker 6. The pin 61 is fixed on the rocker 6 and is used to slide in the slide groove 51 and snap into the side groove 52 when needed to achieve the locking function. The pin 61 is assembled in the slide groove 51. A spring 1 53 is arranged between the rocker sleeve 5 and the rocker 6. The spring 1 53 is arranged between the rocker sleeve 5 and the rocker 6 to provide a rebound force when the rocker 6 is pulled out, so that the rocker 6 can automatically reset. A connecting rod 62 is arranged at the end of the far threaded rod 2 of the rocker 6, and a handle 7 is arranged on the connecting rod 62. The connecting rod 62 connects the rocker 6 and the handle 7, so that the handle 7 can rotate around the connecting rod 62. The handle 7 is a part operated by the user, and the rocker 6 is driven to rotate by rotating the handle 7 .

[0029] The two sides of the slide groove 51 close to the side groove 52 are respectively provided with mounting columns 54. The sides of the two slide grooves 51 close to the side groove 52 are both equipped with mounting columns 54, and the mounting columns 54 are used to install the rubber columns 55.

[0030] The opposite sides of the two mounting posts 54 are flush with the two side edges of the slide slot, that is, when the rubber posts 55 are not installed, since the opposite sides of the two mounting posts 54 are flush with the two side edges of the slide slot 51, when the spring 1 53 retracts the rocker 6, the rocker 6 will not be blocked when retracting in the slide slot 51, and the spring 1 53 quickly retracts the rocker 6, which may easily cause harm to the user. The opposite sides of the two mounting posts 54 are provided with semicircular grooves, and the rubber posts 55 are provided in the semicircular grooves, and the distance between the two rubber posts 55 is less than the width of the slide slot 51. After the rubber posts 55 are installed on the two mounting posts 54, since the distance between the two rubber posts 55 is less than the width of the slide slot 51, during the process of the spring 1 53 retracting the rocker 6, the pin 61 will be stuck by the rubber posts 55, slowing down the retraction speed of the rocker 6, and the user has enough time to take his hand away, preventing the retraction from being too fast and causing harm to the user. In addition, when the pin 61 is stuck by the rubber column 55, the friction force of the rubber column 55 on the pin 61 is smaller than the elastic force of the spring 1 51 at this time. Therefore, after a period of time, the pin 61 will be separated from the rubber column 55 under the action of the spring 1 53, and the rocker 6 will continue to be retracted into the rocker sleeve 5.

[0031] A wedge-shaped groove 63 is provided on the surface of the connecting rod 62 close to the handle 7. A second spring 65 is fixedly provided in the deeper part of the wedge-shaped groove 63. The wedge-shaped groove 63 is provided on the connecting rod 62 to accommodate the second spring 65, and through its wedge-shaped structure, the handle 7 can be tightened on the connecting rod 62 when it is reset. The second spring 65 is fixed in the deeper part of the wedge-shaped groove 63 and on the handle 7, and is used to automatically reset the handle 7 and tighten it on the connecting rod 62 after the handle 7 is released, so as to prevent the handle 7 from tripping the medical staff.

[0032] The other end of the second spring 65 is fixedly connected to one end of the handle 7 near the rotating seat 64. The second spring 65 is arranged at the bottom of the handle 7, so that the user will not be blocked by the second spring 65 when the handle 7 is turned outward. In addition, such an arrangement can also make the second spring 65 more gentle when the handle 7 is retracted, and it is not easy to injure the user.

[0033] The connecting rod 62 is provided with a rotating seat 64, and the handle 7 is rotatably connected to the rotating seat 64. The deeper part of the wedge-shaped groove 63 is close to the rotating seat 64. The rotating seat 64 is provided on the connecting rod 62 for the rotation connection of the handle 7, so that the handle 7 can be rotated around the connecting rod 62.

[0034] Working principle: When the angle of the movable bed board 3 needs to be adjusted, first pull the rocker 6 out of the rocker sleeve 5 until the pin 61 on the rocker 6 is pulled to a position flush with the side groove 52, then turn the handle 7 out, and start rotating the rocker 6. When the rocker 6 starts to rotate, since the pin 61 is located at a position flush with the side groove 52, as the rocker 6 rotates, the pin 61 will be stuck in the side groove 52, thereby completing the locking of the spring 1 53, preventing the user from having to overcome the rebound force of the spring 1 53 when rotating the rocker 6 due to the rebound force, which makes the user more laborious. The rotation of the rocker 6 drives the rotation of the rocker sleeve 5, and further drives the threaded rod 2 integrated with the rocker sleeve 5 to rotate, thereby making the connection move, and finally adjusting the angle of the movable bed board 3. After the movable bed board 3 is adjusted to a suitable position, the rocker 6 is rotated back a certain distance so that the pin 61 is located in the slide groove 51 again. At this time, the handle 7 is released. Since there is no locking of the side groove 52, the spring 1 53 will reset the rocker 6 when it is reset. At the same time, the spring 2 65 located in the wedge groove 63 will also tighten the handle 7 on the connecting rod 62 when it is reset. During the resetting process of the rocker 6, due to the blocking effect of the rubber column 55, the user can have enough time to withdraw the operating hand to prevent the user from being injured by the retraction too quickly. In this way, the locking spring offsets the spring restoring force when using the rocker 6, which is more labor-saving, and the handle 7 is further retracted to prevent the handle 7 from tripping medical staff and reducing the workload of ward management.
