Specific embodiment

With reference to embodiment, the technical solution of the utility model is described in further detail, but not structure Any restrictions of pairs of the utility model.

Embodiment 1:

With reference to Fig. 1-9, a kind of multipurpose pneumostop fixture including cylinder body 1 and is connected to dynamic on cylinder body 1 Power output end 2,2 end of power output end are equipped with limited block 3, and the limited block 3 is preferably tightened in power output The nut at end；The power output end 2 is arranged with the body of the elastically deformable between limited block 3 and cylinder body 1 4；The limited block 3 is equipped with the gas delivery port 31 for exporting compressed gas.

The body 4 is preferably silica gel sheath, can be restored after wear-resisting, pressure-resistant, compression, the body 4 can also certainly Think other elastoplastic.

In the process of running, output power the water inlets that end 2 is incorporated into radiator water chamber first, this when body 4 With the diameter matches of water inlet.Then power output end 2 moves, and body 4 is driven to compress between limited block 3 and cylinder body 1, Body 4 is thicker and cooperates with inlet seal.The gas source of peripheral hardware pressurizes to water chamber to 31 gas injection of gas delivery port.

It is realized it should be noted that specific implementation below may be selected in gas delivery port 31, other can also be used Mode enables extraneous gas source to be input to gas delivery port 31.For example, being equipped with an air inlet pipe in the side wall of cylinder body 1 Road is simultaneously connected on limited block 3 by hose across silica gel sheath, but this is not the preferred embodiment of the present embodiment.

Preferably, the part that the power output end 2 extends in cylinder body 1 is arranged with spring (attached drawing is not shown) For becoming easy the reset of power output end 2.

In the present embodiment, first gas input pipe 21 is equipped in the power output end 2, in the limited block 3 Equipped with second gas input pipe 32, the first gas input pipe 21, second gas input pipe 32, gas delivery port 31 are successively Connection.Setting in this way, can be more simplified by the structure of equipment, does not need any subsidiary conduit actually.
