Abstract
The utility model relates to grease guns and discloses a high-low pressure grease gun. The high-low pressure grease gun comprises a grease bucket, an aluminum head and a handle. The aluminum head is disposed at the top end of the grease bucket, a large piston and a high-pressure piston are disposed in the aluminum head, a seal ring is disposed on the outer side of the large piston, the high-pressure piston is parallelly disposed above the large piston provided with an adjusting rod. By the high-low pressure grease gun, high flow and high pressure can be achieved simultaneously, grease can be filled fast by the high flow, blocked grease paths can be broken through by the high pressure, and grease can be filled by the high flow. The high-low pressure grease gun is convenient and fast due to that fact that switching between a high-pressure mode and a low-pressure mode can be completed only by adjusting the adjusting rod.
Description
Technical field
The utility model relates to grease gun, has related in particular to a kind of high low pressure grease gun.
Background technique
Lose flow under the high pressure, can't obtain high pressure under the big flow, high low pressure exchanges needs off-load again to carry out.Grease gun is a kind of hand-operated tools of giving the machinery grease up, traditional grease gun comprises oil-storing barrel, be loaded on the piston of oil-storing barrel rear end, the thrust mechanism that piston rod and spring are formed and the fuel-displaced mechanism of rod-type rifle head that links with the oil-storing barrel front end, generally speaking, when not smooth as oil circuit, grease gun can not be directly used, oil circuit be cleared up earlier; If when refueling, need high low pressure to transform, general grease gun operates pretty troublesome.
Summary of the invention
The utility model can not use this shortcoming simultaneously at high low pressure in the grease gun in the prior art, and a kind of high low pressure grease gun is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The high low pressure grease gun comprises oil drum, aluminium head and handle, and the oil drum top is provided with the aluminium head, and aluminium head inside is provided with big piston and high pressure piston, and the big piston outside is provided with seal ring, and the top parallel with big piston is provided with high pressure piston, and big piston is provided with adjustable lever.Adjustable lever is used for regulating working state, when adjustable lever snaps into big piston lower position, big piston and small piston move simultaneously, this moment, big piston worked, directly can obtain the oiling of big flow, when adjustable lever was transferred to big piston horizontal position, big piston and high pressure piston moved simultaneously, this moment, big piston was inoperative, directly by the high pressure piston effect.
In the big piston rod of the direct precession of adjustable lever, rotary regulating lever drives big piston rotation.Adjustable lever is fixed with big piston, and when regulating adjustable lever, big piston is also along with the adjustable lever motion.
Big piston edge is provided with lining, and big piston is provided with shaft block ring, and shaft block ring contacts with piston spring, and piston spring contacts with the aluminium end surface, is provided with first steel ball, first little spring and first Cock screw at the big piston of aluminium head corresponding position.Big piston is at when refueling, and lubricated parts need not this situation design of high pressure, and are convenient and swift like this, increase work efficiency.
Be provided with second steel ball, second little spring and second Cock screw at aluminium head corresponding position high pressure piston, high pressure piston and piston brace rod screw mutually, and the high pressure piston edge is connected with handle by rivet.High pressure piston is that when oil circuit was obstructed, the high pressure piston of this product carried out work for the obstructed this situation of the oil circuit that leads to the oiling parts designs, and working pressure can reach 18000psi and dredge oil circuit more easily, refuels then.
The aluminium head is connected with handle by link, and the handle below is provided with taper knob.Handle is that flat hard rigid material is made, and directly makes to grasp not only hard but also damage hand of handle, adds that taper knob not only can protect handle to provide convenience for the person of benefiting from.
The utility model has significant technique effect owing to adopted above technological scheme:
The utility model can obtain high flow capacity simultaneously, and high pressure can be filled with butter in the time of high flow capacity fast, and high pressure energy is got through oil circuit rapidly when oil circuit is obstructed, can fill with butter by high flow capacity then.Need not unloading during two kinds of modes swap of the utility model high low pressure only needs the adjusting adjustable lever to finish, convenient and swift.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is partial enlarged drawing of the present utility model.
The toponym that each number designation refers in the accompanying drawing is as follows: 1-rivet, 2-piston brace rod, 3-shaft block ring, 4-high pressure piston, 5-link, 6-aluminium head, 7-the first steel ball, 8-the first little spring, 9-the first Cock screw, 71-the second steel ball, 81-the second little spring, 91-the second Cock screw, 10-big piston, 11-oil drum, 12-seal ring, 13-piston spring, 14-taper knob, 15-handle, 16-adjustable lever, 17-lining.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
The high low pressure grease gun, as shown in Figure 1, comprise oil drum 11, aluminium head 6 and handle 15, oil drum 11 tops are provided with aluminium head 6, aluminium head 6 inside are provided with big piston 10 and high pressure piston 4, big piston 10 outsides are provided with seal ring 12 for one section, and the top parallel with big piston 10 is provided with high pressure piston 4, and big piston 10 is provided with adjustable lever 16.
In big piston 10 bars of adjustable lever 16 direct precessions, rotary regulating lever 16 drives big piston 10 rotations.Along with the rotation of adjustable lever 16, big piston 10 also can rotate.
Working procedure: when adjustable lever 16 is transferred to big piston 10 lower positions, big piston 10 acts on simultaneously with high pressure piston 4, mainly be to obtain big flow butter, when adjustable lever 16 rotates to position with big piston 10 levels, at this moment, big piston 10 moves simultaneously with high pressure piston 4, but big piston 10 is inoperative, directly high pressure piston 4 effects.Need not unloading during two kinds of modes swap of high low pressure only needs the adjusting adjustable lever to finish, convenient and swift.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
