Abstract
The utility model relates to a cylinder cover structure for an inflating pump. The cylinder cover structure comprises a cylinder cover covering an inflating pump body, wherein the cylinder cover is provided with a three-way air path which is communicated with an air outlet channel arranged on the inflating pump body; the top face of the cylinder cover is further provided with an air hole for balancing air pressure in the three-way air path; an inlet of the air hole is provided with a sealing gasket; an outlet of the air hole is provided with an end cover; an elastic piece is arranged between the end cover and the sealing gasket; and the cylinder cover structure for the inflating pump is characterized in that a groove with a polygonal cross section is arranged in the outer surface of the end cover. Compared with the prior art, the groove arranged in the end cover can be used as an assembling hole to be used; an assembling tool is inserted into the groove so that the end cover can be rotated; the end cover is mounted on the air hole and the assembling is convenient and easy; and after the end cover is mounted, the whole structure is compacted and an extra space is not occupied; and in a mounting process, the tool is not contacted with peripheral parts.
Description
Technical field
The utility model relates to gas-filled pump, specifically refers to a kind of cylinder cover structure of gas-filled pump.
Background technique
The cylinder cap of gas-filled pump is provided with the tee union that is connected with the gas-filled pump outlet passageway.In order effectively to cushion the air pressure in the outlet passageway, guarantee the stable of outlet passageway internal air pressure, the top of this tee union is provided with pore, be provided with gasket seal in this pore, the port of pore is provided with end cap, and this end cap screw thread is threaded with pore, is provided with elastic component between end cap and the gasket seal.When the outlet passageway internal air pressure was higher than setting pressure, elastic component can be in the effect lower compression of air pressure inside, the gasket seal come-up, and the gas in the outlet passageway releases in pore, and the air pressure in the outlet passageway is reduced; When the air pressure in the outlet passageway was reduced to design pressure, sealed air cushion was under the effect of elastic component elastic force, and automatic-sealed is lived the entrance of pore.
In the prior art, end cap adopts the outer-hexagonal bolt usually, and it need to use spanner or special-purpose instrument that it is tightened in the pore of cylinder cap.Because the space of gas-filled pump inside is narrower and small, the installation of end cap needs meticulous, with other parts around avoiding damaging, assembles pretty troublesomely, and the outer-hexagonal bolt takes up room greatly.
Summary of the invention
That technical problem to be solved in the utility model is that the present situation for prior art provides a kind of compact structure, additionally do not take up room and assembles is easy, can not touch the gas-filled pump cylinder cover structure of parts on every side.
The utility model solves the problems of the technologies described above the technological scheme that adopts: this gas-filled pump cylinder cover structure, comprise the cylinder cap that covers on the gas-filled pump body, described cylinder cap be provided be arranged on the gas-filled pump body on three air vents that are connected of outlet passageway, and also be provided with the pore for the described three air vent internal air pressures of balance on the end face of described cylinder cap, the entrance of this pore is provided with gasket seal, the outlet of pore is provided with end cap, is provided with elastic component between described end cap and the described gasket seal; It is polygonal groove that the outer surface that it is characterized in that described end cap is provided with cross section.
For suitable with existing instrument, preferably, described polygonal is hexagon.
Described elastic component is spring.
Compared with prior art, the groove that the utility model is opened on the end cap can be used as the pilot hole use, assembly tool plugged get final product rotary end cover in the groove, end cap is installed on the pore, assemble easy, and compact overall structure after installing can additionally not take up room, and the parts around instrument can not touch when installing.
Description of drawings
Fig. 1 is the floor map of the utility model embodiment cylinder cap assembly structure;
Fig. 2 is the longitudinal sectional view of Fig. 1;
Fig. 3 is the schematic perspective view of the utility model embodiment decomposition texture.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, this gas-filled pump comprises be used to the cylinder cap 1 that covers on the gas-filled pump body (not shown) with cylinder cover structure, cylinder cap 1 be provided be arranged on the gas-filled pump body on three air vents 2 that are connected of outlet passageway (not shown), also be provided with the pore 3 for the described three air vent internal air pressures of balance on the end face of cylinder cap, the entrance of this pore is provided with gasket seal 4, the outlet of pore is provided with end cap 5, is provided with spring 6 between end cap 5 and the gasket seal 4; It is hexagonal groove 7 that the outer surface of end cap is provided with cross section.
During installation, in the groove that hexagonal bar insertion end is covered, rotate, end cap can be installed on the pore, assemble easyly, and compact overall structure after installing can additionally not take up room, and instrument can not touch parts on every side when installing.
Claims (3)
1. gas-filled pump cylinder cover structure, comprise the cylinder cap that covers on the gas-filled pump body, described cylinder cap be provided be arranged on the gas-filled pump body on three air vents that are connected of outlet passageway, and also be provided with the pore for the described three air vent internal air pressures of balance on the end face of described cylinder cap, the entrance of this pore is provided with gasket seal, the outlet of pore is provided with end cap, is provided with elastic component between described end cap and the described gasket seal; It is polygonal groove that the outer surface that it is characterized in that described end cap is provided with cross section.
2. gas-filled pump cylinder cover structure according to claim 1 is characterized in that described polygonal is hexagon.
