The air compressor bringing convenience to oil injecting is convenient to operate.
Description
Technical field
The utility model belongs to a kind of air compressing field, is specifically related to a kind of oiling air compressor easily.
Background technique
Traditional air compressor needs frequent oiling to raise, its oiling place is generally the surface of contact of connecting rod and bent axle, all generally that an oil groove is set on connecting rod or bent axle, and crankshaft-and-connecting-rod is all arranged on the inside of housing, so housing need to be taken apart to ability oiling in the time of oiling, operation is trouble very, time-consuming again.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is the problem of air compressor oiling trouble.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of oiling air compressor easily, comprises housing, bent axle and sealing plug; Described bent axle includes a bent axle body and is connected the eccentric coupling shaft connecting in bent axle body two ends, described bent axle body and coupling shaft are arranged in housing, and coupling shaft and housing is side walls hinged, the axial end of wherein said coupling shaft is provided with an axial oil hole, described oil hole is led to the circumferential surface of bent axle body by the axial end of coupling shaft, the sidewall of described housing is provided with and the axial identical closed hole of oil hole, and described sealing plug passes from closed hole, and is tightly connected with oil hole and closed hole.
The circumferential surface direction that described oil hole leads to coupling shaft is provided with a through hole through circumferential surface, and described through hole is connected with oil hole.
Between described coupling shaft and sidewall, be provided with a bearing, described bearing is fixedly mounted on sidewall, and hinged with coupling shaft.
The internal surface of described bearing is provided with the arc surface of an indent, described arc surface this just to through hole.
Described sealing plug is hexagonal endoporus screw.
(3) beneficial effect
Oiling of the present utility model air compressor easily, by the axial vane surface of a coupling shaft being set to the oil hole of the circumferential surface of bent axle body, described oil hole is axially identical with the closed hole of housing sidewall, make, between staff, oil gun is carried out to oiling through closed hole to oil hole, thereby without the oiling of handling housing, easy to operate, and design a through hole that is led to coupling shaft circumferential surface direction by oil hole, thereby in oil hole oiling, lubricant oil can be expelled to hinged place between coupling shaft and housing simultaneously, thereby further make oiling convenient, and make air compressor overall structure simpler.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
A kind of oiling air compressor easily as shown in Figure 1, Figure 2 and Figure 3, comprises housing 1, bent axle 2 and sealing plug 3, described bent axle 2 includes a bent axle body 21 and is connected the eccentric coupling shaft 22 connecting in bent axle body 21 two ends, described bent axle body 21 and coupling shaft 22 are arranged in housing 1, and coupling shaft 22 is hinged with the sidewall 11 of housing 1, the axial end of wherein said coupling shaft 22 is provided with an axial oil hole 23, described oil hole 23 is led to the circumferential surface of bent axle body 21 by the axial end of coupling shaft 22, the sidewall 11 of described housing 1 is provided with and the axial identical closed hole 12 of oil hole 23, by the axial vane surface of a coupling shaft 22 being set to the oil hole 23 of the circumferential surface of bent axle body 21, described oil hole 23 is axially identical with the closed hole 12 of housing 1 sidewall 11, make, between staff, oil gun is carried out to oiling through closed hole to oil hole, thereby without the oiling of handling housing, easy to operate.After oiling operation completes, described sealing plug 3 passes from closed hole 12, and is tightly connected with oil hole 23 and closed hole 12, and operation is very easy, simple in structure.
Between described coupling shaft 22 and sidewall 11, be provided with a bearing 4, described bearing 4 is fixedly mounted on sidewall 11, and hinged with coupling shaft 22.The internal surface of described bearing 4 is provided with the arc surface 41 of an indent, described arc surface 41 this just to through hole 24, arc surface 41 surface smoothings, this structure can excessively penetrate into lubricant oil between bearing 4 and coupling shaft 22, infiltrates effective.
The circumferential surface direction that described oil hole 23 leads to coupling shaft 22 is provided with a through hole 24 through circumferential surface, described through hole 24 is connected with oil hole 23, can in injecting toward bent axle body 21 directions, be expelled to the joint between bearing 4 and coupling shaft 22 by through hole 24 by this structure, thereby remove the step of injecting toward the joint between bearing 4 and coupling shaft 22 in addition from, made oiling convenient and simple.
Described sealing plug 3 is hexagonal endoporus screw.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
