DETAILED DESCRIPTION

[0021] 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.

[0022] like Figure 1 and Figure 3 As shown, the present invention provides a wire expansion and contraction device, which mainly winds the wire by rotating the rotating frame 6.

[0023] The wire retracting device includes a storage box 1, which includes a first shell 2 and a second shell 3 that are buckled with each other. A receiving cavity 4 for receiving the wire is provided inside the storage box 1. An opening 5 communicating with the receiving cavity 4 is provided at the bottom of one side and the top of the other side of the storage box 1. A rotating frame 6 is provided inside the receiving cavity 4. The rotating frame 6 is rotatably connected to the first shell 2, and the wire is wound by rotating the rotating frame 6.

[0024] A fixed squeezing roller 7 is fixedly installed on the inner wall of the opening 5 close to the rotating frame 6, and a movable squeezing roller 8 is movably installed up and down on the inner wall of the opening 5 away from the rotating frame 6. The distance between the fixed squeezing roller 7 and the movable squeezing roller 8 is adjusted by moving the movable squeezing roller 8 up and down, so as to match the wire diameter and squeeze and fix the wire.

[0025] In clinical practice, cable ties or binding bands are usually used to store overlong wires, but when the length of the wires needs to be extended or shortened, the cable ties or binding bands need to be untied to rearrange the wires, which is inconvenient to use. Currently, there are also retractable wire storage devices, but the storage device and the wires are integrated into one device, and it is impossible to store existing wires such as hospital instruments. In addition, there are many hospital instruments with various wire diameters. Therefore, it is necessary to develop a device that can conveniently store existing wires of various diameters such as hospital instruments.

[0026] In this embodiment, by separating the first shell 2 from the second shell 3, the middle part of the wire can be placed in the storage box 1, and the wire can be wound by rotating the rotating frame 6 so that the wire is stored in the storage box 1. At the same time, the fixed squeezing roller 7 and the movable squeezing roller 8 are squeezed against each other to clamp the wire at the opening 5 to prevent the wire from being easily pulled out of the storage box 1. The adjustable movable squeezing roller 8 makes this device suitable for wires of different diameters.

[0027] In actual use, 1. separate the first shell 2 from the second shell 3;

[0028] 2. Place the middle of the wire to be stored into the rotating frame 6, and place the two sides of the wire into the two openings 5 ​​in sequence. For medical instruments where wires already exist, the wires can be directly fixed and stored starting from the middle of the wires;

[0029] 3. Adjust the distance between the fixed squeezing roller 7 and the movable squeezing roller 8 so that the wire to be collected can just pass through;

[0030] 4. The first shell 2 and the second shell 3 are buckled together to form a storage box 1, and the wires pass through the storage box 1;

[0031] 5. Rotate the rotating frame 6, and the wire is wound around the rotating frame 6 and stored in the accommodating cavity 4;

[0032] 6. Hold the wires on both sides of the storage box 1 and apply force on both sides, and the wires inside the storage box 1 will be pulled out.

[0033] The specific structure of the rotating frame 6 is described in detail below. The rotating frame 6 includes a support plate 9 arranged parallel to the first shell 2, and a rotating rod 10 is fixedly connected to the side of the support plate 9 close to the first shell 2. The rotating rod 10 is rotatably connected to the first shell 2, and the rotating rod 10 passes through the first shell 2, and a rotating block 11 is fixedly connected to the end of the rotating rod 10 away from the support plate 9;

[0034] The support plate 9 is fixedly connected to two fixing rods 12 on one side close to the second housing 3, and a gap 13 is provided between the two fixing rods 12, so that the wire is placed inside the gap 13 and is wound along with the rotation of the rotating frame 6. After opening the first housing 2 and the second housing 3, the wire is placed inside the gap 13, and both sides of the wire are placed into the opening 5 in sequence, and then the support plate 9 is driven to rotate by rotating the rotating block 11, thereby driving the two fixing rods 12 to rotate and winding the wire.

[0035] In order to improve the stability of the rotation of the fixing rod 12, Figure 2As shown, an annular groove 17 is provided on the inner wall of the second housing 3, and the two fixing rods 12 are both arranged inside the annular groove 17, and when the rotating frame 6 rotates, the two fixing rods 12 are both slidably connected with the annular groove 17. The fixing rod 12 is arranged in the annular groove 17, and as the fixing rod 12 rotates, the fixing rod 12 slides inside the annular groove 17, and the annular groove 17 limits the fixing rod 12, thereby improving the rotation stability of the fixing rod 12.

[0036] The specific structures of the fixed squeezing roller 7 and the movable squeezing roller 8 are described in detail below. Figure 4 As shown, the fixed squeezing roller 7 and the movable squeezing roller 8 both include a fixed frame 14 and a rotating roller 15, and both ends of the rotating roller 15 are rotatably connected to the fixed frame 14. The movable squeezing roller 8 is fixedly connected with a threaded rod 16 on the side away from the fixed squeezing roller 7, and the threaded rod 16 passes through the first shell 2 and is threadedly connected to the first shell 2. The distance between the fixed squeezing roller 7 and the movable squeezing roller 8 is adjusted by rotating the threaded rod 16. Rotating the threaded rod 16 makes the fixed squeezing roller 7 approach or move away from the movable squeezing roller 8, thereby adjusting the distance between the fixed squeezing roller 7 and the movable squeezing roller 8, so that the distance between the fixed squeezing roller 7 and the movable squeezing roller 8 just matches the diameter of the wire, and can fix the wire so that the wire cannot pass through the opening 5 when not affected by external force. When the wire passes through the opening 5 under the action of external force, due to the friction force, the rotating roller 15 is driven to rotate, which is conducive to the movement of the wire.

[0037] An elastic layer is fixedly connected to the outer surface of the rotating roller 15, so that the elastic layer is deformed when being squeezed by an external force. The elastic layer is provided to protect the wire and prevent the rotating roller 15 from crushing the wire.

[0038] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
