Description
Technical Field
[0001] The utility model belongs to the field of filling gun discharge structures, in particular to a safety locking and closing discharge structure of a filling gun. Background Art
[0002] Floral water is primarily used for masking odors, sterilizing, disinfecting, cleaning, and adding fragrance. It generally has a pure, unscented aroma, and even at temperatures as low as -5°C, it remains turbid and resistant to precipitation. For this reason, floral water is increasingly popular, becoming a popular summer hygiene product for repelling mosquitoes, relieving itching, sterilizing, and removing body odor. Filling floral water from a container into a package requires a filling gun inserted into the container.
[0003] However, the existing filling gun lacks an effective locking and closing structure when in use, so when the filling gun does not need to discharge liquid, it is easy for the opening to remain open, causing the filled liquid to leak out, thereby resulting in a waste of resources.
[0004] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking improvement, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created. A safety locking and closing discharge structure of a filling gun is provided to solve the problem that when the existing filling gun is in use, due to the lack of an effective locking and closing structure, it is easy for the opening to remain open when the filling gun does not need to discharge liquid, resulting in leakage of the filled liquid, which in turn leads to waste of resources. Utility Model Content

[0007] As a preferred embodiment, a guide rod passes through the inner side of the catheter. The main body of the guide rod is a cylindrical structure, and a connecting head is fixedly connected to the right side of the guide rod. The diameter of the connecting head is smaller than that of the guide rod.
[0008] As a preferred embodiment, a through hole is formed inside the connecting head. The through hole is a connecting hole, and the connecting hole and the connecting head together form a limiting structure.
[0009] As a preferred embodiment, a support rod is fixedly connected to the outer side of the guide rod. The main body of the support rod is a cylindrical structure. There are two support rods in total, and the two support rods are arranged in an opposite and staggered manner on the left and right sides inside the guide rod.
[0010] As a preferred embodiment, the side of the support rod away from the guide rod is in contact with the inner wall of the catheter, and the catheter and the support rod together form a lifting structure for the guide rod.
[0011] As a preferred embodiment, a connecting end is fixedly connected to the left side of the guide rod, and a positioning head is fixedly connected to the left side of the connecting end.

A positioning pin 305 is installed inside this through hole, and the positioning pin 305 is used to pass through the end cover 303, the sealing ring 302 and connect with the positioning head 301.
[0025] Among them, a guide rod 2 passes through the inner side of the conduit 1. The main body of the guide rod 2 is a cylindrical structure. A connecting head 201 is fixedly connected to the right side of the guide rod 2. The diameter of the connecting head 201 is smaller than the diameter of the guide rod 2.
