Description

Technical Field

[0001] This utility model relates to the field of device connection technology, specifically a connection component for medical devices. Background Technology

[0002] Connecting tubing in medical equipment requires specialized connecting components. A tubing connector is a compact device made of stainless steel and rubber components that achieves sealing and pressure resistance. No treatment of the tubing ends is required during installation. Simply slip the connector over the two tubing ends to be connected, tighten the side hollow tube, and the locking teeth will grip the tubing end surface for a secure, closed connection. The sealing sleeve adheres tightly to the tubing, ensuring a tight seal. Normally, when using a tubing connector, first press the two tubing sections together, open the connector, insert the tubing connection, close the connector, and then secure the two screws with nuts. After a period of use, the nuts may loosen, causing the internal tubing to loosen. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a connecting component for medical devices, which has the advantages of being firmly fixed and not easily loosened, thus solving the problem of loosening after a period of use.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connecting component for medical devices, comprising an inner ring, an inner tooth fixedly connected inside the inner ring, an outer ring connected outside the inner ring, a metal plate fixedly connected to the outer ring, a hollow tube fixedly connected inside the metal plate, a screw connected to the hollow tube, and two nuts threadedly connected to the screw. A connecting piece is installed between the two nuts, and a pull ring is connected to the connecting piece. A spring is installed between the two ends of the pull ring, and the top of the pull ring is hooked onto the metal plate via a hook.

[0007] Preferably, there are two hollow tubes, and the two hollow tubes are connected by two screws.

[0008] Preferably, a movable iron ring is installed on each of the left and right sides of the outer ring, and a flat-head screw is installed on each of the upper and lower sides of the movable iron ring.

[0009] Preferably, a plurality of spring pads are fixedly installed inside the movable iron ring, and the spring pads are evenly distributed in a circular shape on the inner wall.

[0010] Preferably, there are multiple internal teeth, which are arranged in a ring array inside the inner ring.

[0011] Preferably, threaded holes are provided on both sides of the movable iron ring, and screws are threadedly connected to the movable iron ring through the threaded holes.

[0012] Compared with the prior art, the present invention provides a connecting component for medical devices, which has the following advantages:

[0013] 1. This pipe connection device uses a pull ring installed on a metal plate. The top of the pull ring is hooked onto the metal plate to perform secondary fixation of the fixing device. This solves the problem that the nut may loosen after the screw is fixed. After the pull ring is fixed, the fixing force used for fixing the pipe connection device becomes more stable.

[0014] 2. This pipe connection device, by adding a tightening device on each of the left and right sides of the pipe connection device, increases the force on both sides of the pipe connector. The device clamps the left and right sides of the pipe, and the force of tightening and loosening the screws makes the force on both sides greater and more stable, thereby making the connection of this pipe connection device more stable.

[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 1-3A connecting component for a medical device includes an inner ring 1, with multiple internal teeth 2 fixedly connected inside the inner ring 1 in a circular array. An outer ring 3 is connected to the outside of the inner ring 1, with movable iron rings 11 mounted on both sides of the outer ring 3. Threaded holes are provided on both sides of the movable iron rings 11, through which screws 14 are threadedly connected. Multiple spring washers 13 are fixedly installed inside the movable iron rings 11, evenly distributed in a circular pattern on the inner wall. Flat-head screws 12 are also installed on the top and bottom sides of the movable iron rings 11. A metal plate 4 is fixedly connected to the outer ring 3, with hollow tubes 5 fixedly connected inside the metal plate 4. There are two hollow tubes 5 connected by two screws 6. The hollow tubes 5 are connected to the screws 6, and the screws 6 are threaded with nuts 7. There are two nuts 7. A connecting piece 8 is installed between the two nuts 7. A pull ring 9 is connected to the connecting piece 8. A spring 10 is installed between the two ends of the pull ring 9. The top of the pull ring 9 is hooked onto the metal piece 4 by a hook. This pipe connection device uses a pull ring installed on the metal piece and the top of the pull ring hooked onto the metal piece to perform secondary fixation of the fixing device.
