Abstract

The utility model relates to a dual-purpose inflator, which is composed of a handle, a piston, a cylinder body of the inflator, a one-way valve, an air outlet pipe and a base, the cylinder body of the inflator is connected with an umbrella-shaped straight pipe through concave nuts; an umbrella part of the umbrella-shaped straight pipe is supported on skirt edges of the lower ends of concave nuts; a gasket is arranged between the umbrella part and the lower part of the cylinder body of the inflator; the lower end of the umbrella-shaped straight tube is connected with the base. The inflator can be used for inflation and hydraulic monitors, has the advantages of simple structure and easy manufacture and is particularly suitable for be widely used for countries.

Description

Dual-purpose pump

The utility model relates to a kind of tire inflatable tool, but particularly a kind of dual-purpose pump of double as hydraulic giant purposes.

In daily life, employed pump when people inflate to bicycle tyre generally all is made up of handle, piston, air cylinder body, one-way valve, gas cylinder cylindrical shell and steam outlet pipe etc.This pump except be used for the inflation, do not possess the purposes that other are arranged, therefore, its purposes is single, can not make the best use of everything.

It is a kind of except can be used for inflation that the purpose of this utility model is to provide, and can also make the dual-purpose pump that hydraulic giant uses.

The purpose of this utility model can be achieved as follows: this dual-purpose pump, mainly form by the piston that links to each other with handle, air cylinder body and base, the lower end of described air cylinder body is detachable the connection by female nut and umbrella shape straight tube, the umbrella portion of umbrella shape straight tube props up on the shirt rim of female nut lower end, between umbrella portion and the air cylinder body lower end is packing ring, and the lower end of umbrella shape straight tube is passed female nut and is connected with base.

The utility model is made the detailed description in a step below in conjunction with accompanying drawing:

Fig. 1 makes the structural representation of pump time spent for the dual-purpose pump of the utility model;

Fig. 2 is the plan view of packing ring in Fig. 1 of the dual-purpose pump of the utility model;

Fig. 3 makes the structural representation of hydraulic giant time spent for the dual-purpose pump of the utility model;

In Fig. 1, handle 1 is fixed by the bar of nut and piston 2, and piston 2 places in the air cylinder body 3, has one-way valve on the piston 2, and is similar with common pump.Air cylinder body can be that metal or plastic cement are made, and there is a lid 11 its upper end, and there is one section outside thread that cooperates with female nut 51 its lower end.Female nut 51 links together air cylinder body 3 and umbrella shape straight tube 6, during connection, earlier the back being passed in the lower end of umbrella shape straight tube from the upper end of female nut 51 passes from the lower end, because it is that female nut is the big and lower end young (as shown in fig. 1) of upper end-hole that the concave bottom of female nut has the shirt rim, therefore the lower end of female nut is not crossed by the umbrella portion of umbrella shape straight tube, can only prop up on the shirt rim of female nut, then packing ring 7 is placed on above the umbrella portion of umbrella shape straight tube, to guarantee sealing, again female nut is screwed in by screw-thread fit with air cylinder body, the plan view of packing ring 7 as shown in Figure 2, the perforation of one shape of slit is arranged in the middle of it, be actually a perforation pad.The lower end of umbrella shape straight tube is being threaded by sealing with base 4.A high-pressure gas container 10 is arranged on base 4 and ride 12, steam outlet pipe 9 is used for pressurized gas are transported to tire etc., and it is that gas is only flowed toward a direction that a plurality of one-way valve purposes are arranged on the base 4.

In Fig. 3, show pump and make the schematic representation of hydraulic giant time spent, compared to Figure 1, its handle, piston and air cylinder body are constant, difference is to remove with the umbrella shape straight tube and with the bottom, packing ring 7 is placed on the shirt rim of lower end of female nut 51, is tightened in air cylinder body then, just can obtain a hydraulic giant.

When dual-purpose pump was done the pump use, a umbrella shape straight tube that only needs to link to each other with base was fixed and can be used as daily pump with female nut and air cylinder body.When being used as hydraulic giant and using, only need packing ring and female nut are fixed and can be used as the hydraulic giant of daily sprinkling usefulness with air cylinder body.

Certainly, female nut also can adopt other structural type such as two ends all have screw thread respectively with air cylinder body and umbrella shape straight tube all for being threaded, and the middle projection as the shirt rim of female nut that a ring-type is arranged can reach the purpose of this utility model equally.So long as the structure that obtains from the design's design also should belong within the protection domain of the present utility model.

By adopting said structure, common pump is become be detachable two-part, the function of particularly utilizing female nut to make pump tightly not have inflation has also had the function of using as hydraulic giant simultaneously, therefore not only can be used as tyre inflation such as bicycle with but also can be used as the hydraulic giant when spraying such as crop and use, simple in structure, cost is very low, has reached the effect of dual-use material, has good market prospects so be particularly suitable for using in the vast rural area.

Claims
