Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides a connection structure of thoracic drainage tube, includes drainage tube 1 and connector 2, the end fixed mounting of drainage tube 1 has spacing ring 3, spacing ring 3 peg graft in connector 2, be provided with in the connector 2 with the inboard looks spiro union of the end of drainage tube 1 screwed pipe 4, the opening 5 of symmetry has been seted up to the lateral wall of connector 2, be provided with the trip 6 that is spacing in spacing ring 3 in the opening 5, the lateral wall of trip 6 is provided with the perk subassembly, the lower extreme of connector 2 is connected with connecting line 7.

Insert spacing ring 3 in connector 2, then swivelling joint head 2, screwed pipe 4 and drainage tube 1 spiro union, drainage tube 1 drive spacing ring 3 to the bottom removal of connector 2, until trip 6 card is on spacing ring 3, spacing fixed to spacing ring 3, avoid not hard up and unexpected pipe phenomenon that takes off, when need separating, only need press the perk subassembly, the removal orbit when driving trip 6 and breaking away from spacing ring 3 separation, then rotate connector 2, accomplish the separation of drainage tube 1 and connector 2.

Specifically, the inner diameter of the connector 2 is matched with the inner diameter of the limiting ring 3.

Specifically, the lower end of the limiting ring 3 is concave to the inner side to form a cone shape, so that the clamping connection of the limiting ring 3 and the clamping hook 6 is facilitated.
