Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a locking mechanism for pulse air pressure spray water guns. Background Technology
[0002] The fire extinguishing principle of pulse air pressure spray water guns is to use compressed air as power, which is sprayed out by the ultra-fast opening exhaust valve in a very short time, pushing the fire extinguishing agent in the water tank and launching it out at extremely high speed. The friction and collision between air and liquid molecules produce atomized liquid particles, which have great kinetic energy and can penetrate the flames and rising airflow, directly shooting into the stove. After the liquid particles vaporize, the flame temperature drops rapidly, achieving the purpose of extinguishing the fire. Pulse air pressure spray water guns are characterized by rapid operation and deployment, water saving and high efficiency, environmental protection and high mobility. No additional power supply is required during use, and various fire extinguishing additives can be used as needed. They are also easy to use and maintain.
[0003] There is a connecting round tube sleeve between the locking screw nut and the front barrel of the pulse air pressure spray water gun. Currently, when people use the continuous sleeve to lock the pulse air pressure spray water gun, not only are multiple parts required, but the process is also complicated, which greatly reduces the practicality of the equipment. Therefore, those skilled in the art provide a locking mechanism for pulse air pressure spray water guns to solve the problems mentioned in the background art. Utility Model Content

[0007] As a further improvement of this utility model: the outer surface of the water storage pipe is connected to a connecting pipe, and the inner wall of the connecting pipe is connected to a second sealing ring.
[0008] As a further improvement of this utility model: each of the positioning holes has a fixed nut threadedly connected to its inner wall, and the valve seat has two sets of O-rings inside.
[0009] As a further improvement of this utility model: the outer surface of the water storage pipe is provided with two sets of threaded holes, and the inner wall of each threaded hole is threaded with a fixing stud.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This locking mechanism for pulse air pressure spray water guns, through the cooperation of connecting pipes, fixing studs, connecting sleeves, baffles, locking nuts, positioning grooves, positioning holes, and fixing nuts, not only reduces weight and machining parts and lowers costs, but also reduces the overall weight and machining cycle of the pulse gun, thereby significantly increasing the production efficiency of pulse air pressure spray water guns and making it easier for people to lock the pulse air pressure spray water guns.

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Please see Figures 1-5 In this embodiment of the utility model, a locking mechanism for a pulse air pressure spray water gun includes a water storage pipe 2, two sets of valve seats 1 installed on the outer surface of the water storage pipe 2, a connecting sleeve 5 snapped onto the outer surface of the water storage pipe 2, a locking nut 7 snapped onto the outer surface of the connecting sleeve 5, a baffle 6 provided between the locking nut 7 and the connecting sleeve 5, a positioning groove 11 opened on the outer surface of the connecting sleeve 5, a first sealing ring 12 installed on the inner wall of the connecting sleeve 5, and two sets of positioning holes 13 opened on the outer surface of the locking nut 7. This mechanism not only reduces weight and processing parts and lowers costs, but also reduces the overall weight and processing cycle of the pulse gun, thereby significantly increasing the production efficiency of the pulse air pressure spray water gun and facilitating the locking of the pulse air pressure spray water gun. This solves the problem in the background art that there is a connecting round tube sleeve between the locking nut and the front barrel of the pulse air pressure spray water gun. Currently, when people use the continuous sleeve to lock the pulse air pressure spray water gun, not only are multiple parts required, but the process is also complicated, which greatly reduces the practicality of the equipment.
[0022] The outer surface of the water storage pipe 2 is connected to the connecting pipe 3, and the inner wall of the connecting pipe 3 is connected to the second sealing ring 14. The inner wall of each positioning hole 13 is threaded with a fixing nut 15. The valve seat 1 is provided with two sets of O-rings 8, which not only makes the sealing effect of the equipment better, but also makes it convenient for people to connect the pulse air pressure spray water gun.
[0023] Two sets of threaded holes 9 are opened on the outer surface of the water storage pipe 2. Each threaded hole 9 has a fixed stud 4 threadedly connected to its inner wall. Two sets of positioning plates 10 are fixedly connected to the outer surface of the water storage pipe 2. The connecting sleeve 5 is adapted to the water storage pipe 2, which greatly increases the strength of the water storage pipe 2, and also greatly reduces the weight and the number of processing parts, and reduces the cost, thus reducing the weight of the entire pulse gun and the processing cycle.
[0024] The working principle of this utility model is as follows: First, the water storage pipe 2 can be installed using the valve seat 1. Then, the connecting sleeve 5 and the locking nut 7 can be installed and fixed using the fixing nut 15. Next, the connecting pipe 3 can be connected to the water inlet pipe. The setting of the connecting sleeve 5 and the locking nut 7 can prevent the need for multiple parts and the complicated process when locking the pulse air pressure spray water gun using the connecting sleeve. The setting of the first sealing ring 12, the second sealing ring 14 and the O-ring 8 can prevent the equipment from leaking.
