Background technique
Press, bicycle is except being the traffic tool, it also is one of tool movement of people at present, yet bicycle can be distinguished mountain-climbing car, highway car or city car etc. again, though the bicycle of which kind only, when driving, first heavy travelling comfort and the smoothness of advancing, and travelling comfort and smoothness are to depend on whether tire has enough tire pressures, therefore, moderately with pump tire are inflated and just seem quite important.
And general traditional pump, include a stack shell to I haven't seen you for ages, one wind fairing head is located at stack shell one end, in order to be connected in object to be inflatable, piston rod and piston thereof that one relative stack shell is back and forth inflated, and when inflating, piston is driven by piston rod, and the stack shell inwall produces at a high speed past renaturation friction relatively, and can produce high temperature relatively, the anxiety that distortion is arranged so that make stack shell Yin Gaowen, and in case deform, the tightness between stack shell and the piston will be affected, and the possibility of gas leakage is arranged, the feasible effect of inflating becomes not good, influences working life.
The model utility content
The purpose of this utility model is, a kind of pump of wear resistance is provided, and to solve the defective that prior art exists, it arranges an abrasion-proof structure on the relative position of piston and cylindrical shell, uses the wear resistance that increases pump, and then prolongs the working life of pump.
For achieving the above object, the pump of a kind of wear resistance of the utility model is characterized in that, includes:
One cylindrical shell has one first end and one second end;
One piston rod group is arranged in this cylindrical shell, and can move back and forth between this first end and this second end, and this piston rod group has a piston;
One wind fairing head is installed on first end of this cylindrical shell, in order to be arranged in an object to be inflatable; And
One abrasion-proof structure is arranged on the relative position of this piston and this cylinder inboard wall.
Wherein, this abrasion-proof structure is a ceramic coating.
Wherein, this abrasion-proof structure is a hard membrane layer.
Wherein, this hard membrane layer is a titanizing hard membrane layer.
Wherein, this abrasion-proof structure is an enamel.
Wherein, this abrasion-proof structure is arranged at the inwall of this cylindrical shell.
Pass through said structure, the pump of a kind of wear resistance of the utility model, on the relative position of piston and cylindrical shell, abrasion-proof structure is set, particularly the inwall in cylindrical shell arranges abrasion-proof structure, use the wear resistance that increases cylindrical shell, when making the motion of the relative cylindrical shell of piston and be difficult for producing distortion, do not have the anxiety that produces gas leakage because of distortion, so can increase the working life of pump.

Embodiment
For ease of explanation the utility model represented central idea in above-mentioned novel content one hurdle, express with specific embodiment now.Various different objects are described in the ratio that is suitable for illustrating, size, amount of deformation or displacement amount among the embodiment, but not are drawn in the ratio of actual components, close chat earlier bright.
See also Fig. 1 to shown in Figure 3, Fig. 1 is the External view of the pump of the utility model wear resistance, and Fig. 2 is the exploded view of the pump of the utility model wear resistance, and Fig. 3 is the sectional view of the pump of the utility model wear resistance.The pump 100 of wear resistance of the present utility model comprises a cylindrical shell 10, a piston rod group 20, a wind fairing head 30 and an abrasion-proof structure 40.
Piston rod group 20, pass through the perforation 14 of lid 13, to be arranged in the cylindrical shell 10, and can between first end of cylindrical shell 10 and second end, move back and forth, wherein piston rod group 20 has a piston rod 21, one pistons 22 and is located at piston rod 21 1 ends, piston rod 21 the other ends handle 23 that then is spirally connected, and piston 22 has a concave ring groove 221 in order to a sheathed O type ring 222, and piston 22 end surface are provided with several breach 223.
Abrasion-proof structure 40, be arranged on the relative position of piston 22 and cylindrical shell 10 inwalls, in present embodiment, abrasion-proof structure 40 is arranged at the inwall of cylindrical shell 10, wherein abrasion-proof structure 40 is ceramic coating, it coats the inwall of cylindrical shell 10 with ceramic powder, and has high hardness by pottery, advantages such as high wear resistance, thereby can improve the wear resistance of cylindrical shell 10 inwalls, make its difficult motion because of piston 22 relative cylindrical shells 10, and cause cylindrical shell 10 because wearing and tearing produce distortion, also also can not cause distortion because of the high temperature that relative movement brings, avoid producing because of distortion the situation of gas leakage, also can further prolong the working life of pump 100, wherein, in another preferable enforcement, abrasion-proof structure 40 also can be an enamel, to be coated in the inwall of cylindrical shell 10.
Consult Fig. 4, shown in Figure 5, for the pump of the utility model wear resistance is inflated view.When desiring to inflate, be that first handle 23 with pump 100 outwards spurs, slide to drive piston rod 21 relative cylindrical shells 10, so that extraneous gas is entered cylindrical shell 10 by the perforation 14 of lid 13 interior room 11 tonifying Qi, and O type ring 222 can be resisted against an end of breach 223 in drawing process, concave ring groove 221, breach 223 so gas can be flowed through and room 11 front positions in flowing into; Then the interface 32 of wind fairing head 30 can be arranged in an object to be inflatable 200, tommy bar 33 pivots and ejection moving part 34, and make air flue 341 and passage 15 contrapositions, then be pressed into handle 23 relative cylindrical shells 10 subsequently, and O type ring 222 can be resisted against an end of concave ring groove 221 in process of press in, makes gas can't circulate in the external world, and gas is subjected to piston rod 21 pushings and energy injection gallery 15, make gas enter air flue 341, enter in the object to be inflatable 200 from interface 32 again, and object to be inflatable 200 is inflated.
Consult shown in Figure 6ly, be the partial enlarged drawing of the utility model Fig. 5.Because the inwall of cylindrical shell 10 is provided with abrasion-proof structure 40, when piston 22 is able to relative cylindrical shell 10 motions and be difficult for producing distortion, do not have the anxiety that produces gas leakage because of distortion; Moreover abrasion-proof structure 40 also can be hard membrane layer, and hard membrane layer can be the titanizing hard membrane layer, and hard membrane layer can see through hard sun and handles and form in cylindrical shell 10 inwalls, has the wear resistance that improves cylindrical shell 10 inwalls equally.
Comprehensively above-mentioned, the pump of the utility model wear resistance, on the relative position of piston and cylindrical shell, abrasion-proof structure is set, particularly the inwall in cylindrical shell arranges abrasion-proof structure, it can be ceramic coating, enamel or hard membrane layer, uses the wear resistance that increases cylindrical shell, when making the relative cylindrical shell motion of piston and be difficult for producing distortion, do not have the anxiety that produces gas leakage because of distortion, so can increase the working life of pump.
Above illustrated embodiment is only in order to the utility model to be described, and is non-in order to limit scope of the present utility model.Such as do not disobey various modifications or the variation that the utility model spirit is engaged in, all belong to the category that the utility model is intended to protect.
