Abstract
The utility model relates to a pneumatic trigger cylinder which comprises a cylinder body part and a cylinder cover part which are integrally shaped, wherein the cylinder body part is in a cylindrical shape, and the cylinder cover part is arranged on one side of the cylinder body part. The cylinder body part is provided with a cylindrical cavity which is arranged along the axial direction of the cylinder body part, and the cavity is obliquely arranged in the cylinder body. The cylinder body part and the cylinder cover part are made of aluminum. The pneumatic trigger cylinder has the advantages of low material cost and manual cost, short production and manufacture time, and long service life. The pneumatic trigger cylinder is applicable to fastening tools such as pneumatic triggers, pneumatic picks and the like.
Description
Technical field
The utility model relates to a kind of cylinder, relates in particular to a kind of cylinder that is used on the pneumatic trigger.
Background technology
At present, have pneumatic tool miscellaneous to select and use for the consumer on the market, this fastening air tool main application of wherein pneumatic trigger (perhaps wind big gun) is the dissimilar securing member of dismounting fast and easily.Cylinder in the pneumatic trigger is located at pneumatic trigger inside, and rotor is set in this cylinder and by stream pressure the runner in the cylinder is rotated, and the material that common in the market cylinder adopts is a spheroidal graphite cast-iron, and cylinder body and cylinder cap are that split combines.Because the cylinder body of common cylinder and cylinder cap all are to adopt cast iron to process on the market, therefore on the market material cost of common pneumatic trigger (perhaps wind big gun) cylinder and production and processing cost than higher, and spent time of production and processing is also long, moreover, also has the shortcoming of poor air-tightness owing to the cylinder body and the cylinder cap of common cylinder on the market is that split links together.Former a kind of material of appearance of urgent need in the market and pneumatic trigger (the perhaps wind big gun) cylinder that processing cost is low, air-tightness is good.
The utility model content
Technical problem to be solved in the utility model is to overcome a prior art difficult problem, provides that a kind of consumptive material expense and processing cost are all lower, process time is short, cylinder body hardness is strong, wear-resistant, the pneumatic trigger cylinder of long service life.
For solving the problems of the technologies described above, the utility model provides a kind of pneumatic trigger cylinder, comprises integrated cylinder body portion and cylinder cap portion, and described cylinder body portion is cylindrical, and described cylinder cap portion is located at a side of described cylinder body portion.
Described cylinder body portion has the circular cylindrical cavity that axially is provided with along described cylinder body portion, and described cavity is offset in the described cylinder body.
The cross section of described cylinder body portion and the cross section of described cavity are the off-centre operation structure.
The axis of the axis of described cylinder body cross section and described cavity cross section is for there being the parallel lines of certain intervals apart.
Part between described cylinder body portion and the described cavity is a casing wall, offers left passage and right passage in an end of described cylinder body portion, described casing wall portion away from axis one side of described cavity.
One end is provided with the rotor shaft hole in described cylinder cap portion.
The material of described cylinder body portion and cylinder cap portion is an aluminium.
Owing to adopt said structure, the utlity model has following beneficial effect:
1, because the utility model adopts cylinder body and cavity to be the off-centre operation structure, cylinder body portion and cavity are the off-centre operation structure, in use, cylinder on the pneumatic trigger and rotor are after engaging, blade in the rotor can closely compress the short side cylinder chamber body wall of eccentric arm, blade is pressed tightly more in rotation, stream pressure is big more in the cavity, motive force is just big more, because cylinder body portion and cavity are eccentric structure, can improve the air-tightness and the effect that strengthens stream pressure of the blade of rotor, increase power.
2, because the material of cylinder body portion and cylinder cap portion is an aluminium, and cylinder body portion and cylinder cap portion are formed in one, and the cost of material is low for it, hardness is strong, wear-resistant, long service life.

The specific embodiment
To shown in Figure 5, the pneumatic trigger cylinder of the utility model comprises the integrated cylinder body of aluminium matter portion 1 and cylinder cap portion 8 as Fig. 1, and described cylinder body portion 1 is cylindrical, and described cylinder cap portion 8 is located at a side of described cylinder body portion 1.Described cylinder body portion 1 has the circular cylindrical cavity 5 that axially is provided with along described cylinder body portion 1, and described cavity 5 is offset in the described cylinder body portion 1.
As shown in Figure 2, the cross section of described cylinder body portion 1 and the cross section of described cavity 5 are the off-centre operation structure.The axis 11 of described cylinder body portion 1 cross section and the axis 21 of described cavity 5 cross sections be for there being the parallel lines of certain intervals apart, makes the casing wall thin location 42 of the axis that forms close described cavity 5 on the casing wall 4 between described cylinder body portion 1 and the described cavity 5 and away from the axis casing wall thicker part 41 of described cavity 5.Cylinder body portion 1 also is provided with air inlet duct 7.Cylinder body portion and cavity are the off-centre operation structure, in use, cylinder on the pneumatic trigger and rotor are after engaging, blade in the rotor can closely compress the short side cylinder chamber body wall of eccentric arm, and blade is pressed tightly more in rotation, and stream pressure is big more in the cavity, motive force is just big more, because cylinder body portion and cavity are eccentric structure, can improve the air-tightness and the effect that strengthens stream pressure of the blade of rotor, increased power.
In an end of described cylinder body, described casing wall away from axis one side of described cavity 5, promptly casing wall thicker part 41 offers left passage 2 and right passage 3.Can regulate making left passage 2 be the air admission hole of cylinder by air valve, perhaps right passage 3 is the air admission hole of cylinder.
8 one ends are provided with rotor shaft hole 6 in described cylinder cap portion, are used for making the rotor (not shown) of pneumatic trigger to be stretched out by this rotor shaft hole 6.The material of described cylinder body portion and cylinder cap portion is an aluminium, has that the cost of material is low, advantage easy to process.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
