Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a retractable hook device for a supply room. Background Technology

[0002] The supply room is a crucial department in a hospital, responsible for the collection, cleaning, disinfection, sterilization, and aseptic distribution of medical devices, dressings, and other supplies. Often referred to as the "heart of the hospital" or the "hidden guardian," its core task is to ensure that all reusable medical devices meet sterility standards, directly impacting medical safety, infection control, and patient well-being. For example, when sterilizing reusable ventilator tubing, a heated wire needs to be threaded through the tubing. Currently, traditional methods involve manually inserting a steel wire with a hook into the tubing until the hook emerges from the other end. The hook is then connected to the heated wire, and the wire is used to pull the hook, moving the wire through the tubing. This process is cumbersome, and the wire is typically stored coiled, making threading difficult. Furthermore, fully opening the wire during threading takes up considerable space, making it inconvenient to use. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-4This embodiment provides a technical solution: a retractable hook device for a supply room, including a housing 1, providing space for the retractable hook component. A winding reel 2 is rotatably connected between the front and rear inner walls of the housing 1 via a pivot. A steel wire 3 is wound around the outer arc surface of the winding reel 2. The left end of the steel wire 3 is fixedly connected to the winding reel 2, and the right end of the steel wire 3 passes through the outlet hole of the housing 1 and is provided with a hook 4. The steel wire 3 is wound and unwound by rotating the winding reel 2, reducing the overall space occupied by the device. In use, the reusable ventilator tubing is fitted onto the outer arc surface of the connecting round tube on the right end of the housing 1. The winding and unwound of the steel wire 3 drives the hook 4 to pass through the other end of the reusable ventilator tubing. At one end, a pull hook 4 is used to pull the heating wire through the reusable ventilator tubing. The front surface of the outer shell 1 is equipped with a control switch 9. The input end of the control switch 9 is electrically connected to an external power source to control the start and stop of the entire device. A torsion spring 8 is movably sleeved on the outer arc surface of the rotating shaft of the take-up reel 2. The end of the torsion spring 8 near the center of the rotating shaft is fixedly connected to the take-up reel 2, and the end of the torsion spring 8 away from the center of the rotating shaft is fixedly connected to the inner wall of the outer shell 1. When the steel wire 3 is wound, the take-up reel 2 rotates, and the torsion spring 8 twists to generate torque. Under the action of the torque of the torsion spring 8, the power for the reverse rotation of the take-up reel 2 is provided, which facilitates the winding of the steel wire 3. It also includes a self-extension mechanism 5.

[0021] The self-expanding mechanism 5 includes a fixed conveyor wheel 51, a movable conveyor wheel 52, a friction disc 53, and a clamping plate 54. The fixed conveyor wheel 51 is rotatably connected between the front and rear inner walls of the outer shell 1 via a rotating shaft 2. The movable conveyor wheel 52, which can move up and down, is rotatably connected to the inside of the outer shell 1 via a rotating shaft 3. The movable conveyor wheel 52 is installed in conjunction with the fixed conveyor wheel 51. Friction discs 53 are provided at both ends of the outer arc of the rotating shaft 3. The friction discs 53 are installed in conjunction with the winding reel 2. The clamping plates 54 are slidably connected in the grooves at the right end of the outer shell 1. The three annularly distributed clamping plates 54 move synchronously and with the same amplitude toward the pull hook 4, using the clamping plates 54 to press the reusable ventilator tubing against the outer arc surface of the connecting round tube at the right end of the outer shell 1, thus connecting the reusable ventilator tubing to the outer shell 1. The self-extension mechanism 5 also includes a rotating frame 55 and a motor 56. The rotating frame 55 is vertically slidably connected to the inside of the outer shell 1. The guide frames on the front and rear sides of the rotating frame 55 are vertically slidably connected to the guide columns inside the outer shell 1. The movable conveyor wheel 52 is rotatably connected between the front and rear rotating support plates of the rotating frame 55 via a rotating shaft three. The motor 56 is located on the rear side of the rotating frame 55. The output shaft of the motor 56 is fixedly connected to the rotating shaft three. The input end of the motor 56 is electrically connected to the output end of the control switch 9. The motor 56 is started by the control switch 9. The motor 56 drives the rotating shaft three, the movable conveyor wheel 52 and the friction disc 53 to rotate counterclockwise. When the rotating frame 55 is in the maximum downward position, the steel wire 3 is vertically clamped by the cooperation of the fixed conveyor wheel 51 and the movable conveyor wheel 52. At this time, the friction between the movable conveyor wheel 52, the steel wire 3, and the fixed conveyor wheel 51 causes the movable conveyor wheel 52 and the fixed conveyor wheel 51 to rotate relative to each other, pushing the steel wire 3 to the right and causing the steel wire 3 to extend. When the rotating frame 55 is in the maximum upward position, the movable conveyor wheel 52 separates from the steel wire 3, and the outer arc surface of the friction disc 53 contacts the outer arc surface of the take-up reel 2. At this time, when the rotating shaft 3 drives the friction disc 53 to rotate counterclockwise, the friction between the friction disc 53 and the take-up reel 2 drives the take-up reel 2 to rotate clockwise. At the same time, the torque of the torsion spring 8 drives the take-up reel 2 to rotate in the opposite direction, winding the steel wire 3 and causing the steel wire 3 to retract. The self-extension mechanism 5 also includes an adjusting screw 57, an adjusting disc 58, and a transmission assembly 59. The adjusting screw 57 The screw 57 is threaded into a threaded hole on the surface of the outer casing 1. A handwheel 7 is located at the upper end of the adjusting screw 57. A rotating ring 1 is rotatably connected to the outer arc surface of the handwheel 7's outer ring 1. A rotating ring 2 is rotatably connected to the outer arc surface of the second convex ring on the upper surface of the outer casing 1. A bellows is provided between the first and second rotating rings, and the bellows is movably fitted onto the outer arc surface of the adjusting screw 57. During the rotation of the adjusting screw 57, the first rotating ring rotates relative to the handwheel 7, and the second rotating ring rotates relative to the outer casing 1. The bellows only extends and retracts vertically, providing an external protective barrier for the adjusting screw 57. The lower end of the adjusting screw 57 is rotatably connected to the rotating frame 55. The adjusting disc 58 is rotatably connected to the inside of the outer casing 1. A planar spiral groove is provided on the right side of the adjusting disc 58, and the sliders on the left side of the clamping plate 54 are all slidably connected to the inside of the planar spiral groove.A transmission assembly 59 is provided between the adjusting screw 57 and the adjusting plate 58. The transmission assembly 59 includes an internal hexagonal tube 591, an external hexagonal column 592, a bevel gear 593, a bevel gear ring 594, and a rotating column 595. The rotating column 595 is rotatably connected to a groove on the surface of the rotating frame 55. The lower end of the adjusting screw 57 is fixedly connected to the middle of the upper surface of the rotating column 595. The internal hexagonal tube 591 is rotatably connected to a rotating support plate on the rear inner wall of the outer casing 1. The external hexagonal column 592 is vertically slidably connected inside the internal hexagonal tube 591. 2. The upper end of the external hexagonal column 592 is fixedly connected to the middle of the lower surface of the rotating column 595. The outer arc surface of the internal hexagonal tube 591 is provided with a bevel gear 593. The outer edge of the left side of the adjusting plate 58 is provided with a bevel ring 594, which meshes with the bevel gear 593. By rotating the adjusting screw 57 through the handwheel 7, the adjusting screw 57 is threadedly connected to the screw hole of the outer casing 1. The adjusting screw 57 moves downward, and the rotating column 595 and the rotating frame 55 rotate relative to each other, causing the rotating frame 55 to drive the movable conveyor wheel 52 to move downward. Until the handwheel 7 contacts the surface of the outer casing 1, the rotating frame 55 is in its maximum downward position. At the same time, the outer hexagonal column 592 moves downward and rotates along with the rotating column 595. Through the vertical sliding of the outer hexagonal column 592 and the inner hexagonal tube 591, the inner hexagonal tube 591 drives the bevel gear 593 to rotate. Through the meshing connection between the bevel gear 593 and the bevel gear ring 594, the bevel gear ring 594 drives the adjusting plate 58 to rotate. Under the limiting position of the slide groove at the right end of the outer casing 1, the slider of the clamping plate 54 is positioned on the adjusting plate 58. The spiral groove slides within the spiral groove, causing the three clamping plates 54 to move synchronously and with the same amplitude towards the hook 4. During winding, the adjusting screw 57 reverses. When the rotating column 595 contacts the top wall of the outer casing 1, the rotating frame 55 is at its maximum upward position, and the clamping plates 54 release their pressure on the reusable ventilator tubing. Rubber pads 6 are provided on the sides of the clamping plates 54 near the hook 4. The deformation of the rubber pads 6 increases the friction between the clamping plates 54 and the reusable ventilator tubing, making the tubing more securely fixed.

[0022] The working principle of the retractable hook device for the supply room provided by this utility model is as follows: When the reusable ventilator tubing is sterilized in the supply room, the heating wire needs to be passed through the reusable ventilator tubing. The reusable ventilator tubing is then fitted onto the outer arc surface of the connecting round tube on the right end of the outer shell 1. Then, the adjusting screw 57 is rotated by the handwheel 7. Through the threaded connection between the adjusting screw 57 and the screw hole of the outer shell 1, the adjusting screw 57 moves downward, and the rotating column 595 and the rotating frame 55 rotate relative to each other, causing the rotating frame 55 to drive the movable conveyor wheel 52 to move downward until the handwheel 7 contacts the surface of the outer shell 1. At this time, the rotating frame 55 is in the maximum downward position. By fixing the conveyor wheel 51 and the movable... The conveyor wheel 52 clamps the steel wire 3 vertically. Simultaneously, the outer hexagonal column 592 moves downwards and rotates along with the rotating column 595. Through the vertical sliding of the outer hexagonal column 592 and the inner hexagonal tube 591, the inner hexagonal tube 591 drives the bevel gear 593 to rotate. The bevel gear 593 meshes with the bevel gear ring 594, which in turn drives the adjusting disc 58 to rotate. Limited by the groove on the right end of the outer casing 1, the slider of the clamping plate 54 slides within the spiral groove of the adjusting disc 58, causing the three clamping plates 54 to move synchronously and with the same amplitude towards the hook 4. The clamping plates 54 then press the reusable ventilator tubing against the connection on the right end of the outer casing 1. The outer arc surface of the circular tube connects the reusable ventilator tubing to the outer casing 1. Then, the motor 56 is started via the control switch 9. The motor 56 drives the rotating shaft 3 and the movable conveyor wheel 52 to rotate counterclockwise. Utilizing the friction between the movable conveyor wheel 52, the steel wire 3, and the fixed conveyor wheel 51, the movable conveyor wheel 52 and the fixed conveyor wheel 51 rotate relative to each other, pushing the steel wire 3 to the right. Overcoming the torque of the torsion spring 8, the take-up reel 2 rotates, and the steel wire 3 is wound around the outer arc surface of the take-up reel 2. The steel wire 3 pushes the hook 4 through the inside of the reusable ventilator tubing. Then, the hook 4 is manually connected to the heating wire, and the adjusting screw 57 is rotated in the opposite direction until the rotating column 595 is aligned with the outer casing 1. When the top wall of the rotating frame 55 is in contact with the wire 3, the rotating frame 55 is in the maximum upward position, the movable conveyor wheel 52 is separated from the wire 3, the outer arc surface of the friction disc 53 is in contact with the outer arc surface of the winding disc 2, and the clamping plate 54 is reset, releasing the pressure on the reusable ventilator tubing. At this time, when the rotating shaft 3 drives the friction disc 53 to rotate counterclockwise, the friction between the friction disc 53 and the winding disc 2 drives the winding disc 2 to rotate clockwise. At the same time, with the torque of the torsion spring 8, the winding disc 2 rotates in the opposite direction to wind up the wire 3. The heating wire is pulled through the reusable ventilator tubing by the hook 4. After the wire is threaded, the reusable ventilator tubing can be removed directly.

[0023] It is worth noting that the motor 56 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended to use a NEMA17 model stepper motor. The control switch 9 is equipped with a switch button corresponding to the motor 56 for controlling its switching operation.

[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
