[0002] During dental surgery, it is often necessary to use a silicone tube to flush and clean the human oral cavity. The flushing silicone tube usually includes a silicone tube and a joint installed at the end of the silicone tube. Currently, when installing the silicone tube and the joint, the silicone tube is usually installed on a jig first, the end of the silicone tube is stretched open, and then the joint is inserted into the jig. The jig inserts the joint into the silicone tube. At this time, on the one hand, the end of the silicone tube is easily cracked, and when a person inserts the joint into the jig by hand, it is difficult to insert and it is easy to pinch a person's fingers. Utility Model Content

[0003] In order to improve the problem of inconvenient assembly of silicone tubes and joints, the utility model provides a jig for flushing silicone tubes. The specific technical solution is as follows:

[0004] A jig for flushing a silicone tube comprises a fixing seat, on which a jet tube is arranged, the jet tube is connected to an external air source, the air outlet end of the jet tube is used for inserting a joint, and the air outlet pipe of the jet tube is provided with a cannula for inserting the joint.

[0005] During assembly, first fix the corresponding cannula on the jet tube according to the size of the joint, and the jet tube will spray gas, first put the joint on the end of the cannula, and then insert the silicone tube on the other end of the joint. As the jet tube sprays gas, the gas enters the joint and the silicone tube, forming a thin gas layer on the inner wall of the joint. This gas layer has certain elasticity and lubricity. Due to the fluidity of the gas, it can adapt to the shape of the silicone tube and the joint parts, forming a relatively smooth transition area. This smooth transition not only reduces friction, but also plays a certain lubricating role, making it easier to insert the joint on the cannula and the silicone tube on the joint, improving the convenience of installing the silicone tube and the joint.

[0006] In a specific possible implementation scheme, the air injection pipe is connected to the fixing seat via a connecting assembly;

[0007] The connecting assembly comprises a locking member arranged on the jet pipe, and the fixing seat is provided with a limiting member for fixing the jet pipe, and the locking member is used to lock the limiting member.

[0008] In a specific possible implementation scheme, the fixing seat is provided with a through hole for the air injection pipe to pass through;

[0009] The limiting member comprises at least two limiting grooves arranged on the wall of the through hole, a limiting block is slidably arranged on the limiting groove, the limiting block is used to clamp the jet pipe, and a plurality of tightening springs are arranged between the limiting block and the bottom wall of the limiting groove.

[0010] The jet pipe can be limited by pushing the limit block against the spring to squeeze the jet pipe.

[0011] In a specific possible implementation manner, a plurality of abutment rings are provided on a side of the limit block close to the air injection pipe, and the plurality of abutment rings are evenly distributed along the axial direction of the air injection pipe.

[0012] In a specific feasible implementation scheme, the locking member includes a mounting sleeve that is sleeved on the jet pipe, the mounting sleeve having a sliding groove, the sliding groove corresponding to the limiting groove one by one, a moving block slidingly provided in the sliding groove, a locking spring provided between the moving block and the sliding groove wall, a locking rod inserted into a fixed seat and extending into the limiting groove on the moving block, and a positioning hole for inserting the locking rod on the limiting block.

[0013] In a specific possible implementation scheme, there are two through holes on the fixing base, and the mounting sleeve is located between the two through holes;

[0014] The installation sleeve comprises two half rings, one end surface of the half ring is provided with a groove, and the other end surface is provided with a magnet for inserting into the groove.

[0015] Beneficial technical effects of the utility model:

[0016] 1. The jet tube sprays gas, first put the joint on the end of the cannula, and then insert the silicone tube on the other end of the joint. As the jet tube sprays gas, the gas enters the joint and the silicone tube, forming a thin gas layer on the inner wall of the joint. This gas layer has a certain elasticity and lubricity. Due to the fluidity of the gas, it can adapt to the shape of the silicone tube and the joint parts, forming a relatively smooth transition area. This smooth transition not only reduces friction, but also plays a certain lubricating role, making it easier to insert the joint on the cannula and the silicone tube on the joint, improving the convenience of installing the silicone tube and the joint;

[0017] 2. When installing the jet pipe, first pass the jet pipe through the two through holes, push the limit block to squeeze the jet pipe, then splice the half rings, insert the magnet into the groove, and then circle the two half rings around the outside of the jet pipe. Move the moving block and push the locking rod to insert it into the positioning hole. This can lock the limit block to prevent the limit block from retracting into the limit groove. This allows for easy disassembly and replacement when the jet pipe needs to be replaced. BRIEF DESCRIPTION OF THE DRAWINGS
