Foaming gun

Abstract

The invention provides a foaming gun, which comprises a fixing part; an elastic structure is arranged at the front end of the fixing part and comprises a connecting shaft and an operating part; one end of the connecting shaft is connected with one half of the fixing part; the other end of the connecting shaft penetrates through the other half of the fixing part and then is connected with the operating part; the operating part is used for pushing one half of the fixing part and the other half of the fixing part to be close to each other at the front end so as to lock the fixing part; a first guide part for limiting the operating part to rotate around the connecting shaft is arranged between the other half of the fixing part and the operating part; the first guide part is used for guiding the operating part to be close to / away from the periphery of the fixing part; the fixing part is in a locked state when the operating part is close to the periphery of the fixing part; and the fixing part is in an unlocked state when the operating part gets away from the periphery of the fixing part, so that a tank body is conveniently locked / unlocked.

Description

technical field [0001] The invention relates to the technical field of foaming agent use aids, in particular to a foaming gun. Background technique [0002] Foaming agent is commonly used in production and life, and it is a commonly used material. For ease of use, the foaming agent is packed in a tank and used through a foaming gun or a disposable rubber hose. [0003] The foaming agent, such as polyurethane foam, is usually divided into two types: tube type and gun type. The tube type is generally equipped with a disposable rubber hose, or it can be used only when it is connected to a foaming gun (or called a foaming glue gun). Polyurethane foam is a special polyurethane product filled with polyurethane prepolymer, foaming agent, catalyst and other components in a pressure-resistant aerosol tank. , sound insulation, waterproof. The aforementioned polyurethane foam is a typical foaming agent and is widely used. [0004] When in use, the valve of the tank needs to be opene...

Problems solved by technology

[0004] When in use, the valve of the tank needs to be opened, and the tank is under pressure, so it is necessary to use a foaming gun or a disposable rubber hose, but these two types have their own shortcomings. For the foaming gun, the cost is very high , It is prone to blockage, and it is also required that the tank body must be equipped with a connection part connected to the foaming gun. The common thread is the threaded part, which leads to an increase in the cost of the tank body. For disposable hoses, although the cost is much lower than that of the foaming gun, but During operation, you need to hold the tank with your hand and press the slender handle on the disposable rubber hose with your fingers to open the valve of the tank. It is very inconvenient and laborious to use. In addition, the pressing direction is not easy to control, and it is easy to fail to operate. , which seriously restricts the expansion of users and guarantees the quality of use. Disposable rubber hoses are not suitable for users with small strength, nor are they suitable for users with small hands. Both near and far are greatly restricted. Unless experienced and strong users, it is very difficult to operate and the quality of use is low.

[0005] For this reason, the applicant has carried out in-depth research, and has previously applied for a Chinese utility patent for a styrofoam gun, the patent number is CN201922077735.5, although compared with the existing technology, there has been a huge improvement, that is, " Compared with the original foaming gun, the above-mentioned foaming glue gun does not need the gun barrel and other related structures, there is no problem of clogging, and the cost is greatly reduced. Compared with the disposable rubber hose, it is more convenient for users to use, and at the same time overcomes the problem of using When the user needs to hold the tank body and directly press the slender handle on the disposable rubber hose with the force of the fingers", but the described foam glue gun has not yet solved the problem of how to conveniently lock / unlock the tank body , and reliable, effective
