Description
Technical field
The utility model relates to mechanical engineering technical field, refers to a kind of self-priming grease gun especially.
Background technique
Grease gun is a kind of to the hand-operated tools of machinery grease up.It can select dress iron barral of a gun (iron rifle head) or flexible pipe (flat rifle head) zerk.This product has simple to operate, easy to carry, the plurality of advantages that using scope is wide, is numerous operators of farm machinery, the indispensable instrument of maintenance center.
The grease gun of original technology is because rifle inner carrier suction is large not, can not automatically oiling, with oiling, shovel manually oils, and the piston of triangular form is before easy to wearing and tearing and polishes, the bending of piston head usually causes grease gun work not smooth, to such an extent as to normally can not use grease gun; Need regular replacing, use pretty troublesome.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of self-priming grease gun, to solve the problems of the technologies described above.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of self-priming grease gun, comprise oil suction cylinder, oil suction platen and barral of a gun, one end that described barral of a gun stretches out outside oil suction cylinder is connected with handle, described barral of a gun one end stretched in oil suction cylinder is connected with the rubber piston of double-deck line-surface structure, described rubber piston and the contact form of oil suction cylinder inwall are that line face contacts, the contact of described line face is parallel to be provided with two-layer and to lay respectively at the ora terminalis place, front and back of rubber piston, described barral of a gun is positioned at rubber piston rear end and is socketed with a pushing spring.
The both ends of the surface central part of described rubber piston is respectively equipped with the bowl-shape iron plate of a punching press, and the two ends of described barral of a gun are respectively screwed into a nut with the fixing bowl-shape iron plate of described punching press, and described rubber cup is fixed on described barral of a gun.
Also plastic skeleton is provided with between described pushing spring and the bowl-shape iron plate of punching press.
The oil absorbing end outer wall of described oil suction cylinder is provided with outside thread, and described outside thread is for connecting an oil suction dish, and described oil suction dish is for sealing grease bucket.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, when self-priming grease gun of the present utility model adds butter before every task, first Head for lubricating screw is rather backed out, add and load onto oil suction platen, oil suction platen is allowed to push down butter in oil drum, make oil suction platen and butter close contact, then backward after bar twitching, butter can suck in bucket automatically, when annotating butter, the rubber piston of what grease gun of the present utility model adopted is double-deck line-surface structure, therefore convenient, quick and health, and the shortcoming that must be vented when common grease gun uses can be overcome; Secondly, when ultrahigh pressure refuels, because sealing effect is many times of common oil gun, more ensure pressure during grease gun work, improve effect and the speed of refueling.Oil suction cylinder connects special oil suction platen, and rifle bucket outside oily dirt free when ensure that oil suction, oil absorbing effect is better faster, health more.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the self-priming grease gun of the utility model.
Fig. 2 is the enlarged view in A portion in Fig. 1.
Fig. 3 is the schematic diagram of oil suction dish of the present utility model.
Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of self-priming grease gun, comprise oil suction cylinder 1 and barral of a gun 2, described barral of a gun 2 one end of stretching out outside oil suction cylinder 1 is connected with handle 3, described barral of a gun 3 one end stretched in oil suction cylinder 1 is connected with rubber cup 4, described rubber cup 4 and the contact form of oil suction cylinder 1 inwall are that line face contacts, the contact of described line face is parallel to be provided with two-layer and to lay respectively at the ora terminalis place, front and back of rubber cup 4, described barral of a gun 2 is positioned at rubber cup 4 rear end and is socketed with a pushing spring 5.
The both ends of the surface central part of described rubber cup 4 is respectively equipped with the bowl-shape iron plate 6 of a punching press, and the two ends of described barral of a gun 2 are respectively screwed into a nut 7 with the fixing bowl-shape iron plate 6 of described punching press, and described rubber cup 4 is fixed on described barral of a gun 2.
Plastic skeleton 8 is also provided with between described pushing spring 5 and the bowl-shape iron plate 6 of punching press.
The oil absorbing end outer wall of described oil suction cylinder 1 is provided with outside thread 9, and described outside thread 9 is for connecting an oil suction dish 10, and described oil suction dish 10 is for sealing grease bucket 11.
Oil suction cylinder adopts precision tube to make, inwall is more smooth than common steel tube, oil suction piston adopts accurate oil resistant rubber to make, and there is between the inwall of oil suction cylinder twice tightly combine completely, oil suction side face of piston ring stamped steel bowl is two-sided fixing, oil suction piston is shaped completely when oil suction works, guarantees the sealing stability between oil suction piston and oil suction cylinder inwall.
When self-priming grease gun of the present utility model adds butter before every task, first Head for lubricating screw is rather backed out, add and load onto oil suction platen, oil suction platen is allowed to push down butter in oil drum, make oil suction platen and butter close contact, then backward after bar twitching, butter can suck in bucket automatically, when annotating butter, the rubber piston of what grease gun of the present utility model adopted is double-deck line-surface structure, therefore convenient, quick and health, and the shortcoming that must be vented when common grease gun uses can be overcome; Secondly, when ultrahigh pressure refuels, because sealing effect is many times of common oil gun, more ensure pressure during grease gun work, improve effect and the speed of refueling.Oil suction cylinder connects special oil suction platen, and rifle bucket outside oily dirt free when ensure that oil suction, oil absorbing effect is better faster, health more.
In such scheme, the utility model reasonable in design, can oil suction automatically, without the need to human assistance; The increase of piston thickness can make the life-span increase, and increases the friction between rifle wall simultaneously, makes piston operationally be not easy to bend, and the piston thickeied also can be scraped the oil on oil suction cylinder inwall totally interior pushing in the process of oil, has practicability.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
