Description
Technical Field
The utility model relates to an evacuating device technical field especially relates to an air pump.
Background
The pump bowl is the part commonly used when present vacuum bag evacuation, and present pump bowl is cylindric mostly, and the diameter that can only enlarge the pump bowl to increase the efficiency of bleeding, perhaps adopts two cylindric pump bowls, but the resistance of two cylindric pump bowls bleeding is bigger, and manufacturing cost is also high, and space utilization is not enough, and the pump bowl that the diameter is big is not portable again, so need a pump bowl that bleed efficiently and the volume is little, convenient operation.
Disclosure of Invention
The utility model aims to solve the technical problem that an air pumping tube is provided, simple structure, the internal capacity is big, and it is efficient to bleed, and the resistance of bleeding is little, and is small moreover, convenient to use.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an air pumping cylinder, includes barrel and air pumping handle, the cross-section of barrel be standard track and field runway form, the one end of barrel be provided with the end cover, the middle part of end cover be provided with the extraction opening, the inside of barrel be provided with the piston that matches with the barrel shape, piston one side link to each other with the air pumping handle of the barrel other end through two push rods, the outside of piston and the inside wall of barrel between install the sealing washer.
As right technical scheme a supplement, the piston include two piston pieces of arranging side by side from top to bottom, the piston piece between leave the clearance and link to each other through connecting portion, the sealing washer spacing between two piston pieces.
As a supplement to the technical scheme of the utility model, the cross-section of push rod be the cross.
Has the advantages that: the invention relates to an air pumping cylinder which is simple in structure, large in internal capacity and high in air pumping efficiency, adopts a special standard track-and-field runway shape, adopts a double-rod structure, is small in air pumping resistance and small in size, and has good popularization value.

FIG. 2 is a front view of the structure of the half-section of the present invention;
fig. 3 is an internal structure view of the present invention.
Reference numerals: 1. the device comprises a cylinder body, 2, an end cover, 3, an air extraction opening, 4, an air extraction handle, 5, a push rod, 6, a piston, 7, a piston sheet, 8, a connecting part, 9 and a sealing ring.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1-3. The utility model discloses embodiment relates to an air pump, including barrel 1 and air pumping handle 4, the cross-section of barrel 1 be standard track and field runway form, the one end of barrel 1 be provided with end cover 2, the middle part of end cover 2 be provided with extraction opening 3, the inside of barrel 1 be provided with the piston 6 that matches with the 1 shape of barrel, piston 6 one side link to each other through the air pumping handle 4 of two push rods 5 and the 1 other end of barrel, the outside of piston 6 and the inside wall of barrel 1 between install sealing washer 9.
The cross section of the push rod 5 is in a cross shape, and the cross-shaped push rod 5 is high in strength and not easy to deform.
When the vacuum bag is used, the air exhaust port 3 is aligned with a vacuum valve on the vacuum bag, then the air exhaust handle 4 is pulled by hand, the piston 6 is driven to rapidly reciprocate in the cylinder body 1, and air in the vacuum bag is rapidly exhausted.
The utility model discloses simple structure, barrel adopt special standard track and field runway's shape, and internal capacity is big, and it is efficient to bleed to adopt the double-rod structure, the resistance of bleeding is little, and is small moreover, has fine spreading value.
