Abstract

The invention discloses a technology-hole quick plug. The technology-hole quick plug comprises limiting pins, stretchable pins, a plug body, a rubber gasket, a gasket, a nut, a thread supporting rod and a tension spring. External threads are arranged on the outer edges of one ends of the two limiting pins, screw-driver slots are arranged in the end tops of the other ends of the two limiting pins, and small holes are formed in the pin faces close to one ends of the screw-driver slots; thread holes are formed in the two stretchable pins; a nut handle is arranged on the nut; the head of the thread supporting rod is a cone, and a knurled knob is arranged at the tail; the tension spring is arranged between the small holes in the two limiting pins, and one ends with the external threads of the two limiting pins are arranged in the two thread holes in the stretchable pins respectively; the plug body is arranged between the stretchable pins and the rubber gasket; the gasket is arranged between the rubber gasket and the nut; the cone on the head of the thread supporting rod is arranged in the plug body through the nut, the gasket and the rubber gasket. The technology-hole quick plug is convenient to use, quick and good in sealing performance.

Description

A kind of fabrication hole fast cap
Technical field
The present invention relates to a kind of fabrication hole fast cap, belong to pipeline fitting technical field.
Background technology
Some parts such as cylinder block, cylinder head etc., need to carry out the water pressure test in the mill in order to check the sealing property of foundry goods.But on the side of these parts, being often designed with fabrication hole, this is the scab in order to remove in workpiece cavity more easily, therefore when doing the water pressure test, it is necessary to block these fabrication holes with several plugs simultaneously.There is following defect in existing plug used: using inconvenience, cause the most long, sealing property is poor.
Summary of the invention
To be solved by this invention: to use inconvenience, cause the most long, the technical problem that sealing property is poor.
For solving above-mentioned technical problem, the present invention uses following technical proposals:
A kind of fabrication hole fast cap, including spacer pin 1, telescopic pin 2, plug body 3, rubber washer 4, packing ring 5, nut 6, threaded spreader bar 7 and extension spring 8;Described spacer pin 1 is two, and its outer, one end is provided with external screw thread 101, and other end end backs down and is provided with a screw driver groove 103, is offering aperture 102 on the pin face of screw driver groove 103 one end;Described telescopic pin 2 is two, and it offers screwed hole 201;Described nut 6 is provided with nut handle 601;Described threaded spreader bar 7 head is cone 702, and afterbody is provided with knurled knob 701;Extension spring 8 it is provided with, in two screwed holes 201 that one end of two spacer pin 1 band external screw threads 101 is respectively arranged in telescopic pin between aperture 102 on said two spacer pin 1;It is provided with plug body 3 between described telescopic pin 2 and rubber washer 4;It is provided with packing ring 5 between described rubber washer 4 and nut 6;Cone 702 on described threaded spreader bar 7 head is located in plug body 3 by nut 6, packing ring 5 and rubber gasket 4.
The beneficial effect of employing technique scheme:
The present invention is easy to use, quick, good seal performance.

In figure: 1 spacer pin, 101 external screw threads, 102 apertures, 103 screw driver grooves, 2 telescopic pin, 201 screwed holes, 3 plug bodies, 4 rubber washers, 5 packing rings, 6 nuts, 601 nut handles, 7 threaded spreader bar, 701 knurled knobs, 702 cones, 8 extension springs, 9 parts.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail:
The present invention use schematic diagram as it is shown in figure 1,
The first step: first in plug head insertion process hole, left hand helps plug body 3, the right hand holds the knurled knob 701 of threaded spreader bar 7, and Quick fastening threaded spreader bar 7 in the direction of the clock, by the cone 702 of its head outwardly against two telescopic pin 2, make this plug body 3 cling to rapidly baseplane in fabrication hole, make plug to fall down;
Second step: continue on the other hand to help plug body 3, quickly twist the nut handle 601 on nut 6 clockwise on the other hand, force nut 6 packing washer 5, and by 5 pressure transmission of packing ring to rubber washer 4 so that it is seal the fabrication hole on parts 9;
3rd step: after parts 9 water pressure test uses, when needing dismounting, helps plug body 3 on the other hand, quickly twists the nut handle 601 on nut 6 counterclockwise on the other hand, force nut 6 to loosen packing ring 5;
4th step, left hand helps plug body 3, the right hand holds the knurled knob 701 of threaded spreader bar 7, and the strut 7 that the most quickly unscrews, leaving of its forecone 702 of threaded spreader bar 7, two telescopic pin 2 are under the pulling force effect of extension spring 8, in the hole of retraction plug body 3, make plug can take out in the fabrication hole from parts 9.
