Description

Technical Field

[0001] The utility model relates to the field of recoil machines, in particular to a liquid discharge tool. Background Art

[0002] The recoil mechanism refers to the device that allows the bolt to recoil and lock again after being unlocked and retreated to the end point when an automatic firearm is fired. The recoil mechanism needs regular maintenance. Hydraulic oil is installed inside the recoil mechanism. During maintenance or live ammunition design, the internal oil is dirty and needs to be drained and then new oil is added. The drain port adopts the structure of the valve core. The internal liquid can be drained by squeezing the valve core. Currently, there is no special tool to squeeze the valve core. Usually, a tool such as a long pin is used to push the valve core. This method is not convenient to use force when pushing because of the narrow space. On the other hand, the liquid is directly sprayed from the drain nozzle, which is easy to splash the operator. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a liquid discharge tool, which can discharge liquid very conveniently and easily. Since the liquid will not be sprayed everywhere in a narrow space, it is easy to use.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a liquid discharge tool, comprising an outer cylinder and an inner rod;

[0005] The inner rod is inserted into the outer tube, the inner rod is threadedly matched with the rear end of the outer tube, a connection spacing is left between the front section of the inner rod and the front section of the outer tube, and the inner wall of the outer tube is provided with an internal thread matched with the thread of the outer wall of the liquid nozzle;

[0006] The side wall of the outer cylinder is provided with a drainage hole.

[0007] When in use, the front end of the outer tube is threadedly connected to the discharge nozzle. At this time, the positions of the outer tube and the discharge nozzle are relatively determined, and then the inner rod is rotated. Since the inner rod and the outer tube thread cooperate, the inner rod can be moved forward relative to the outer tube by rotating the inner rod. The inner rod moving forward will push the valve core inside the discharge nozzle. After the valve core is pushed inward, the liquid inside will flow out. This solution pushes the valve core by rotating the inner rod. On the one hand, it can push the valve core more conveniently and labor-savingly, so that the internal liquid can be released smoothly. On the other hand, it can allow the gas to be discharged from the discharge hole to avoid spraying everywhere.

[0008] Preferably, a turning handle is provided at the rear end of the inner rod, so as to better exert force when turning the inner rod.

[0009] Preferably, the rear end of the outer cylinder is provided with an inner edge platform inwardly, and the inner edge platform is provided with a screw hole matched with the inner rod thread, so as to better match the inner rod and keep a distance between the inner rod and the inner wall of the inner cylinder.

[0010] Preferably, the front end of the inner rod is a conical structure so as to push the valve core.

[0011] Preferably, the drainage hole is located at the rear section of the outer tube, and the front section of the outer tube is used to connect the liquid discharge nozzle to ensure that the liquid can flow out of the drainage hole smoothly.

[0012] Preferably, the drainage hole is connected to a drainage nozzle, and the valve is arranged on the drainage nozzle. The drainage nozzle can prevent the liquid from flowing along the outer wall of the outer tube.

[0013] Preferably, a pressure gauge for detecting the hydraulic pressure inside the outer cylinder is provided on the side wall of the outer cylinder, so as to detect the hydraulic pressure.

[0014] Preferably, it also includes an extension tube and an extension rod, one end of the extension tube is threadedly matched with the front section of the outer tube, the other end of the extension tube is threadedly matched with the outer portion of the liquid discharge nozzle, and the rear end of the extension rod is connected to the front end of the inner rod through a connecting tube, so as to discharge liquid in a narrow and inaccessible space.

[0015] Preferably, the rear end of the extension rod is plugged into and matched with the front end of the inner rod through a connecting tube, making the connection more convenient.

[0016] Beneficial effects of the utility model:

[0017] This solution can release the liquid very conveniently and easily. Since the space is small, the liquid will not spray everywhere, and it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The side wall of the outer tube 1 is provided with a drainage hole 5 .

[0026] When in use, the front end of the outer tube 1 is threadedly connected to the liquid discharge nozzle. At this time, the positions of the outer tube 1 and the liquid discharge nozzle are relatively determined, and then the inner rod 2 is rotated. Since the inner rod 2 and the outer tube 1 are threadedly matched, the inner rod 2 can be rotated to move the inner rod 2 forward relative to the outer tube 1. The inner rod 2 moves forward to push the valve core 4 inside the liquid discharge nozzle. After the valve core 4 is pushed inward, the liquid inside will flow out. This solution pushes the valve core 4 by rotating the inner rod 2. On the one hand, it can be more convenient and labor-saving to push the valve core 4 so that the internal liquid can be discharged smoothly. On the other hand, it can allow the gas to be discharged from the drainage hole 5 to avoid spraying everywhere.

[0027] A turning handle 3 is provided at the rear end of the inner rod 2 so as to better exert force when turning the inner rod 2.

[0028] The rear end of the outer tube 1 is provided with an inner edge platform inwardly, and the inner edge platform is provided with a screw hole that is threadedly matched with the inner rod 2. In order to better match the inner rod 2, the inner rod 2 can maintain a distance from the inner wall of the inner tube.

[0029] The front end of the inner rod 2 is a conical structure so as to push the valve core 4.

[0030] The drainage hole 5 is located at the rear section of the outer tube 1. The front section of the outer tube is used to connect the liquid discharge nozzle to ensure that the liquid can flow out of the drainage hole 5 smoothly.
