Plug-in type double-cylinder inflating pump, comprise motor, by motor-driven left and right two cylinders, be coated at the cylinder cover of cylinder, it is characterized in that: the left and right sides of motor is equipped with end cap, the outside of end cap is provided with pump seat, the lower end of described cylinder cover is provided with convex tendon, described pump seat is the container cavity of opening to the inside, pump seat top is provided with the U-shaped socket communicating with container cavity, in described socket walls, have the guide groove matching with convex tendon, on described pump seat, have axial through hole, described end cap is provided with the screwed hole relative with pump seat through hole, when assembling, the guide groove of pump seat moves along convex tendon, screw is threaded and realizes cylinder cover through the through hole of pump seat and the screwed hole of end cap, pump seat, end cap connects, the intracavity diameter of cylinder cover is greater than cylinder bore, between assembling exhaust hood cover and cylinder, all there is space. when assembling, pump seat directly inserts cylinder cover, and cylinder cover and end cap is fixed with screw, thereby end cap, pump seat, cylinder cover three are connected and fixed, easy to connect, simple in structure. the intracavity diameter of cylinder cover is greater than cylinder bore, between assembling exhaust hood cover and cylinder, all exists space freely to dispel the heat, and cylinder cover is connected with pump seat, because cylinder cover is not connected with cylinder, the heat of cylinder is not directly passed to cylinder cover, and cylinder cover temperature is low, can not go out the situation of high thermal deformation.
As the further of technique scheme improved and supplemented, the present invention also comprises following additional technical feature.
Between left hand cylinder cover, right cylinder cover, be provided with to the tracheae guard shield of under shed and be positioned at the handle of tracheae guard shield top, described tracheae guard shield, left hand cylinder cover, right cylinder cover integrated injection molding are shaped, and handle is fixed as one by screw and tracheae guard shield.
Described cylinder cover is provided with louvre, and described convex tendon is positioned at the cylinder cover periphery of louvre below. Louvre, for heat radiation, reduces internal heat.
Described cylinder cover periphery is provided with many upper and lower parallel convex tendons, and convex tendon and guide groove under match, and descends the distance of convex tendon and adjacent convex tendon to be more than or equal to guide groove to the distance of pump seat end face most pump seat upper limb is embedded between cylinder cover two convex tendons. Further improve the reliability connecting.
Described cylinder cover comprises cap, radiating part, connecting portion, and described radiating part and connecting portion are equipped with convex tendon, between described radiating part and cap and between the adjacent convex tendon of radiating part, is equipped with louvre. All there is stopper in the upper-lower position of louvre, can avoid foreign material to enter, and improves the reliability of cylinder operation.
Positive stop strip is arranged at the upper end inwall of pump seat, between two positive stop strips, forms guide groove, to coordinate with the convex tendon on cylinder cover.
Described pump seat bottom is provided with feet.
Beneficial effect: when assembling, pump seat directly inserts cylinder cover, and cylinder cover and end cap are fixed with screw, thereby end cap, pump seat, cylinder cover three are connected and fixed, easy to connect, simple in structure. The intracavity diameter of cylinder cover is greater than cylinder bore, between assembling exhaust hood cover and cylinder, all has space, and cylinder cover is connected with pump seat, because cylinder cover is not connected with cylinder, therefore temperature is low, can not go out the situation of high thermal deformation.
