Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4, an embodiment of the present utility model provides a technical solution: a gastrointestinal endoscope host connecting tube, including a joint body 1, a fixing cap 2 and a locking cover 3. A flow channel 4 is opened in the center of the joint body 1. A plugging nozzle 5 is provided at the left end of the joint body 1. A locking thread 6 is provided on the surface of the plugging nozzle 5. The locking cover 3 is sleeved on the surface of the plugging nozzle 5 and is detachably connected to the plugging nozzle 5. A sliding groove 7 is provided at the right end of the joint body 1. A buckling hole 8 is opened in the center of the fixing cap 2. The fixing cap 2 is sleeved on the surface of the sliding groove 7. A fixing thread 9 is provided inside the fixing cap 2.
[0022] Further improved, the diameter of the sliding groove 7 is smaller than the diameter of the joint body 1, and the diameter of the buckling hole 8 is larger than the diameter of the sliding groove 7 and smaller than the diameter of the joint body 1. By providing a sliding groove 7 with a smaller diameter on the surface of the joint body 1, it is convenient for the fixing cap 2 to slide while limiting the fixing cap 2.
[0023] Further improved, a protruding limiting ring 10 is provided on the surface of the plugging nozzle 5, and the limiting ring 10 is smoothly connected to the plugging nozzle 5. By providing a smoothly connected limiting ring 10 on the surface of the plugging nozzle 5, it is convenient to insert the connecting tube on the surface of the plugging nozzle 5, and at the same time, the connecting tube is supported by the limiting ring 10 to improve the sealing performance of the connection between the connecting tube and the plugging nozzle 5.
[0024] Further improved, a locking hole 11 is provided at the left end of the locking cover 3. An arc-shaped groove 12 is provided on the inner wall of the locking hole 11. The diameter of the locking hole 11 is smaller than the diameter of the limiting ring 10, and the arc-shaped groove 12 is in fit connection with the limiting ring 10. By providing a locking hole 11 with an arc-shaped groove 12 at the left end of the locking cover 3, it is convenient to fit with the limiting ring 10 after the locking cover 3 is tightened, so as to clamp the connecting tube.
[0025] Specifically improved, an anti-slip groove 13 is opened on the surface of the fixing cap 2, and parallel distributed engraved grooves 14 are provided on the surface of the locking cover 3. By providing an anti-slip groove 13 on the surface of the fixing cap 2 and cooperating with the engraved grooves 14 on the surface of the locking cover 3, it is convenient to disassemble and assemble the fixing cap 2 and the locking cover 3, and improve the convenience of use.
[0026] When the present utility model is in use, the locking cover 3 is sleeved on the surface of the connecting tube, and the end of the connecting tube is inserted and connected to the surface of the plugging nozzle 5 of the joint body 1. The locking cover 3 is connected to the locking bolt on the surface of the plugging nozzle 5 to improve the connection stability and sealing performance between the connecting tube and the joint body 1. The joint body 1 is inserted into the interface on the surface of the gastrointestinal endoscope host, and the fixing cap 2 is used for threaded connection.
[0027] The problems solved by the present utility model: Some gastroscope and colonoscope hosts usually have a flexible tube on the surface of the electronic endoscope to facilitate the insertion of the electronic endoscope. The existing flexible tube ends usually adopt integrally connected connectors. Although the integrity of the flexible tube is improved, the flexible tube is prone to damage at the connector during use, and often the entire flexible tube needs to be replaced, increasing the use and maintenance costs. The present utility model uses a connector body 1, a fixing cap 2, and a locking cover 3 to form a connecting pipe connector, improving the convenience of connection between the connecting pipe and the connector body 1. By providing a rotatably connected fixing cap 2 at the front end of the connector body 1, the stability of the connection between the connector body 1 and the gastroscope and colonoscope host is improved. By providing a threadedly connected locking cover 3 at the rear end of the connector body 1, the stability and sealing performance of the connection between the connecting pipe and the connector body 1 are improved.
