[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] See also Figure 1-3 The utility model provides a polypropylene folding combination cover for infusion, including a cover body 1, the lower end of the cover body 1 is fixedly connected to a hollow cylinder 2, the lower end of the hollow cylinder 2 is connected to two insertion cylinders 3, a rubber stopper is provided between the cover body 1 and the hollow cylinder 2, and folding cover structures 4 are symmetrically provided on both sides of the lower end of the hollow cylinder 2, the folding cover structures 4 cover the outer surface of the corresponding insertion cylinder 3, and the middle part of the lower surface of the hollow cylinder 2 is fixedly connected to a fixing structure 5.

[0014] The cover body 1 is fixedly sleeved on the bottle mouth of the infusion bottle, and is connected to the insertion tube 3 through the hollow tube 2, and the infusion tube connector is fixed by the insertion tube 3, which facilitates the insertion of the infusion tube connector. The setting of the two insertion tubes better ensures the practicality of the equipment. Through the function of the folding cover structure 4, it can be effectively dust-proof when not in use. When the hanging bottle is in use, the folding cover structure 4 can be opened to cooperate with the fixing structure 5 to fix the infusion tube connector, thereby ensuring the firmness of the installation of the infusion tube connector and avoiding separation from the infusion bottle. It is highly safe and practical.

[0015] The folding cover structure 4 includes a vertical plate 41, which is fixedly assembled on the lower end of the hollow tube 2. The lower end of the vertical plate 41 is rotatably connected to a top cover 42, which covers the outer surface of the insertion tube 3. The vertical plate 41 is connected to the top cover 42 through a torsion spring 43.

[0016] To open the folding cover structure 4, it is necessary to bend the top cover 42 downward, causing the torsion spring 43 to deform and store elastic force. At this time, the infusion tube connector is inserted into the insertion tube 3 and clamped by the fixing structure 5. At this time, the top cover 42 is loosened, and according to the elastic force of the torsion spring 43, the infusion tube connector will be pressed and firmly clamped in the fixing structure 5.

[0017] The fixing structure 5 includes a sleeve 51, which is fixedly assembled on the lower end of the hollow tube 2. The inner wall of the sleeve 51 is screwed with a threaded section 52, and the lower end of the threaded section 52 is fixedly assembled with a rotating rod 53. The two sides of the rotating rod 53 are symmetrically assembled with buckles 54. The inner wall of the insertion tube 3 is plugged with an infusion tube connector, and the buckle 54 is clamped with the infusion tube connector.

[0018] As needed, first rotate the rotating rod 53 to drive the threaded section 52 to move up and down on the inner wall of the sleeve 51, and adjust the longitudinal position of the buckle 54. It can be adjusted freely as needed. After the adjustment is completed, insert the infusion tube connector into the insertion tube 3 and pass through the rubber stopper. At the same time, use the buckle 54 to clamp and fix the infusion tube connector, and cooperate with the folding cover structure 4 to effectively clamp it.

[0019] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
