Abstract
The utility model discloses an oil injection device, which comprises an oil injection device shell, wherein an oil injection cavity is arranged in the oil injection device shell; a piston rod is arranged in the oil injection cavity; an oil outlet is formed in the oil injection cavity; an oil inlet is formed in the lower end of the oil injection cavity; a first one-way valve from the oil inlet to the oil outlet is arranged between the oil inlet and the oil outlet; a second one-way valve outwards from the oil injection cavity is arranged on the oil outlet. Due to the adoption of the structure, during oil injection, oil can be still injected if positive pressure exists in a lubricating oil tank.
Description
Technical field
The utility model relates to air-conditioning technical field, relates in particular to a kind of oil gun.
Background technique
Oil gun is the common tool that various machines is added to lubricant oil, and pressure cannot be born in general oil gun inside, can not when there is malleation engine oil case inside, in machine, inject lubricant oil.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of oil gun, this lubricant oil that can inject equally when can having malleation to lubricating oil tank inside.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of oil gun, comprise oil gun housing, in described oil gun housing, there is oiling chamber, described oiling is provided with piston rod in chamber, and described oiling is provided with oil outlet on chamber, and lower end, described oiling chamber is provided with filler opening, between described filler opening and described oil outlet, be provided with the first one-way valve from filler opening to oil outlet, on described oil outlet, be provided with second one-way valve outside from oiling chamber.Adopt this structure in the time of oiling, still can carry out oiling if there is malleation in lubricating oil tank.
The utility model compared with prior art, has following beneficial effect: this oil gun of the utility model, in the time of oiling, still can carry out oiling if having malleation in lubricating oil tank.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1, a kind of oil gun, comprise oil gun housing 1, in described oil gun housing 1, there is oiling chamber 2, in described oiling chamber 2, be provided with piston rod 3, on described oiling chamber 2, be provided with oil outlet 4,2 lower ends, described oiling chamber are provided with filler opening 5, between described filler opening 5 and described oil outlet 4, be provided with the first one-way valve 6 from filler opening 5 to oil outlet, on described oil outlet 4, be provided with second one-way valve 7 outside from oiling chamber 2.Adopt this structure in the time of oiling, still can carry out oiling if there is malleation in lubricating oil tank.
This oil gun in use, in the time that piston rod moves upward from filler opening oil suction, when piston rod moves downward due to one-way valve effect, even if there is malleation lubricant oil can not flow to filler opening in lubricating oil tank, lubricant oil oil outlet is to oiling in lubricating oil tank, makes this oil gun can be to there being the lubricating oil tank oiling of malleation.
