Description
Technical field
The utility model relates to automobile exhaust auxiliary brake device technical field, is specifically a kind of automobile exhaust auxiliary brake device dust-protection type cylinder.
Background technique
Cylinder is execution components and parts important in automobile exhaust auxiliary brake device.At present, the vent carrying out gas exchanges in the cylinder of automobile exhaust auxiliary brake device with the external world is opened in end cap, and vent is then adopt common through hole.Adopt the cylinder of this structural design, cylinder body is carrying out in the process of gas exchanges with the external world, and the impurity such as the dust in air, particle are easily drawn into cylinder interior through vent, affect the service behaviour of cylinder, reduction of service life, have great negative effect.
In order to solve the problems of the technologies described above, this case produces thus.
Summary of the invention
The purpose of this utility model is: provide a kind of reliable working performance, the automobile exhaust auxiliary brake device dust-protection type cylinder of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of automobile exhaust auxiliary brake device dust-protection type cylinder, comprise cylinder body, piston is provided with in cylinder body, piston is connected with piston rod, spring is provided with between piston and the end cap of cylinder body, the sidewall of described cylinder body is provided with annular projection, and the bottom sidewall of cylinder body being positioned at annular projection offers vent, and the arranged outside being positioned at vent in the central cavity of annular projection has filter core.
Further, described filter core is limited in the central cavity of annular projection by jump ring.
Further, described filter core is copper filter core.
Further, described vent and annular projection concentric are arranged.
The utility model compared with prior art, have the following advantages: the utility model automobile exhaust auxiliary brake device dust-protection type cylinder, by vent is offered on a side wall of the cylinder, and by filter core, the air entered in cylinder body is filtered, the impurity such as the dust in elimination air, particle, guarantee that clean air enters into cylinder interior, ensure the stable work in work of cylinder, reliable, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model automobile exhaust auxiliary brake device dust-protection type cylinder.
Shown in figure: 1, cylinder body 2, piston 3, piston rod 4, annular projection 5, vent 6, filter core 7, jump ring 8, spring 9, end cap.
Embodiment
Below by drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, a kind of automobile exhaust auxiliary brake device dust-protection type cylinder, comprises cylinder body 1, is provided with piston 2 in cylinder body 1, piston 2 is connected with piston rod 3, is provided with spring 8 between the end cap 9 of piston 2 and cylinder body.
The above is prior art, main innovate point of the present utility model is: the sidewall of cylinder body 1 is provided with annular projection 4, the bottom sidewall of cylinder body 1 being positioned at annular projection 4 offers vent 5, and the arranged outside being positioned at vent 5 in the central cavity of annular projection 4 has filter core 6.
During concrete enforcement, filter core 6 is round pie structure, and the central cavity of its shape, size and annular projection 4 matches, and filter core 6 just in time can be embedded in the center cavity of annular projection 4.
In order to make the layout of vent 5 more reasonable, promote the gas exchanges inside and outside cylinder body 1, in the present embodiment, vent 5 and annular projection 4 concentric are arranged.
In order to make in the central cavity being limited to annular projection 4 that filter core 6 can be stable, in the present embodiment, the arranged outside being positioned at filter core 6 in the central cavity of annular projection 4 has jump ring 7.
In order to make the filtering effect of filter core 6 better, longer service life, in the present embodiment, filter core 6 is copper filter core 6.
The utility model automobile exhaust auxiliary brake device dust-protection type cylinder, by vent 5 being opened on the sidewall of cylinder body 1, and by filter core 6, the air entered in cylinder body 1 is filtered, the impurity such as the dust in elimination air, particle, guarantee that clean air enters into cylinder body 1 inner, ensure the stable work in work of cylinder, reliable, long service life.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff in the scope not departing from this invention thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its scope protected according to right.
