Description

Liquid nitrogen rifle convenient to use Technical Field The utility model belongs to the technical field of liquid nitrogen guns, and particularly relates to a liquid nitrogen gun convenient to use. Background The liquid nitrogen gun is a professional tool utilizing the low temperature characteristic of liquid nitrogen. The liquid nitrogen injection device can instantaneously generate extremely low temperature by injecting liquid nitrogen, is commonly used for rapidly freezing biological samples in scientific research experiments and low-temperature treatment materials in the industrial field, and is also used for rapidly freezing foods in the food processing industry so as to keep the freshness and taste of the foods, and the operation needs professional protection. When the existing liquid nitrogen gun is used, the liquid nitrogen discharge flow of the liquid nitrogen gun cannot be conveniently adjusted, and different experiments and production links have different requirements on the liquid nitrogen flow. For example, in food processing, the freezing speed and degree required by different kinds and sizes of foods are different, and if the liquid nitrogen gun cannot conveniently adjust the flow, the optimal freezing condition cannot be provided for various foods, and the quality and taste of the foods are affected. If the adjustment operation steps are not convenient enough and delay more time, the liquid nitrogen discharge flow cannot be controlled accurately because more time is consumed, and in order to solve the problems, it is necessary to design a liquid nitrogen gun convenient to use. Disclosure of utility model The present utility model provides a convenient to use liquid nitrogen gun to solve the above-mentioned problems in the prior art. The liquid nitrogen gun comprises a tank body, wherein a liquid injection pipe is communicated and fixedly arranged on the tank body, a valve is arranged on the liquid injection pipe, a cross pipe is communicated and fixedly arranged at the top of the tank body, a guide pipe is communicated and fixedly arranged at the top of the cross pipe, and a nozzle is communicated and fixedly arranged at one end of the guide pipe. The utility model discloses a jar, including the cross pipe, sealing plug, connecting axle, worm and worm wheel meshing and transmission have the auto-lock nature between the two, jar body side fixed mounting has the handle, the recess has been seted up to the handle upper end, be equipped with first pivot in the recess, first pivot rotatable mounting is on the handle, fixed mounting has the carousel in the first pivot, be provided with link gear on the jar body, first pivot drives the worm through link gear and rotates. Preferably, the handle surface is provided with anti-slip lines. Preferably, the linkage mechanism comprises a supporting plate, the supporting plate is fixedly arranged on the tank body, a second rotating shaft is rotatably arranged on the supporting plate, a first synchronous belt mechanism is arranged between the second rotating shaft and the first rotating shaft, and the second rotating shaft and the first rotating shaft are in transmission through the first synchronous belt mechanism. Preferably, a second synchronous belt mechanism is arranged between the second rotating shaft and the worm, and the second rotating shaft and the worm are driven by the second synchronous belt mechanism. Preferably, the corners of the handle are rounded. Preferably, a liquid level monitoring and displaying device is arranged on the tank body. Preferably, a protective cover is fixedly arranged on the tank body, the protective cover covers the first synchronous belt mechanism and the second synchronous belt mechanism, and the rotary disc is arranged outside the protective cover. Preferably, the outer surface of the tank body is provided with a wear-resistant coating.
