Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a rear grip for a pulse air pressure spray water gun. Background Technology

[0002] The fire extinguishing principle of a pulse air pressure spray water gun 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. The pulse air pressure spray water gun is characterized by rapid operation and deployment, water saving and high efficiency, environmental protection and high mobility. No additional power supply is required during use. Various fire extinguishing additives can be used as needed. It is easy to use and maintain. The rear handle is an important component of the pulse air pressure spray water gun.

[0003] However, the stability of the current rear grip is poor. Since the device generates a large impact force during operation, the large impact force can easily damage the grip, thereby reducing the service life of the device. Therefore, those skilled in the art have provided a pulse air pressure spray water gun rear grip to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a rear grip for a pulse air pressure spray water gun to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pulse air pressure spray water gun rear grip includes a main valve body, a grip handle is snapped onto the bottom surface of the main valve body, two positioning holes are formed on the upper surface of the grip handle, a first auxiliary hole is formed on the front side of the grip handle, a second auxiliary hole is formed on the front side of the grip handle, a connecting hole is formed on the inner wall of the main valve body, and a set screw is formed on the left side of the grip handle.

[0007] As a further improvement of this utility model: a water guide hole is provided on the upper surface of the grip handle, and a first sealing ring is fixedly connected to the inner wall of the water guide hole.

[0008] As a further improvement of this utility model: the inner walls of the two positioning holes are fixedly connected with second sealing rings, and the first sealing ring and the two second sealing rings are both made of rubber.

[0009] As a further improvement of this utility model: the upper surface of the grip handle is provided with a mounting hole, and the inner wall of the mounting hole is threaded with a positioning pin.

[0010] As a further improvement of this utility model: a protective pad is fixedly connected to the upper surface of the grip handle, and the outer surface of the grip handle is coated with anti-corrosion paint.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The rear handle of this pulse air pressure spray water gun, through the design of the grip handle, positioning hole, first auxiliary hole, second auxiliary hole, connecting hole, set screw and water guide hole, allows people to fix the main valve body in both directions, making the main valve body more stable during operation and thus extending the service life of the equipment. The design of the first sealing ring, second sealing ring and protective gasket not only improves the sealing effect of the equipment, but also protects the main valve body.

[0017] 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.

[0018] 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.

[0019] Please see Figures 1-3 In this embodiment of the present invention, a rear grip for a pulse air pressure spray water gun includes a main valve body 1, a grip handle 2 snapped onto the bottom surface of the main valve body 1, two positioning holes 3 on the upper surface of the grip handle 2, a first auxiliary hole 4 and a second auxiliary hole 5 on the front surface of the grip handle 2, a connecting hole 6 on the inner wall of the main valve body 1, and a set screw 7 on the left side of the grip handle 2. This makes the main valve body 1 more stable during operation, thereby significantly increasing the service life of the main valve body 1. This solves the problem mentioned in the background art that the stability of the current rear grip is poor. Because the equipment generates a large impact force during operation, the large impact force can easily damage the grip, thereby reducing the service life of the equipment.

[0020] The upper surface of the handle 2 is provided with a water guide hole 8. The inner wall of the water guide hole 8 is fixedly connected with a first sealing ring 9. The inner walls of the two positioning holes 3 are fixedly connected with second sealing rings 10. The first sealing ring 9 and the two second sealing rings 10 are all made of rubber, which can improve the sealing effect of the main valve body 1 and prevent leakage between the main valve body 1 and the handle 2.

[0021] The upper surface of the handle 2 is provided with a mounting hole 11, and a positioning pin 13 is threadedly connected to the inner wall of the mounting hole 11. A protective pad 12 is fixedly connected to the upper surface of the handle 2. The outer surface of the handle 2 is coated with anti-corrosion paint, which not only protects the main valve body 1, but also makes the handle 2 corrosion resistant.

[0022] The working principle of this utility model is as follows: First, the main valve body 1 can be snapped together with the handle 2. Then, the main valve body 1 can be fixed by using the first auxiliary hole 4, the second auxiliary hole 5 and the positioning hole 3. The setting of the first sealing ring 9 and the second sealing ring 10 can prevent leakage between the main valve body 1 and the handle 2. The setting of the positioning hole 3, the first auxiliary hole 4 and the second auxiliary hole 5 can prevent the main valve body 1 from being damaged due to insecure connection during the operation of the equipment.

[0023] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
