Abstract
The utility model relates to a reducing plug which comprises a plug body, a control handle and a seal ring, and is structurally characterized in that: the plug body is a hollow cavity body and is constructed by the series connection of a rigid top plate with a central through hole, a flexible sleeve, a rigid bottom plate with a central bolt hole, the top and bottom of the plug body are rigid bodies, and the peripheral wall of the plug body is flexible, the bolt hole is arranged in the center of the bottom of the hollow cavity body and the through hole is arranged in the center of the top of the hollow cavity body; the control handle is a connecting body with a screw rod on one end and a handle on the other end, one end of the screw rod of the control handle has a thread structure and the other end is a cylinder. The utility model has the beneficial effects that: 1. compared with prior art, the sealing effect is good; 2. the circumference of the plug can be adjusted so that the plug can be inserted in or pulled out from a pipe mouth or container mouth.
Description
Technical field
The utility model relates to a kind of reducing stopper, is a kind of reducing stopper that is used to seal the mouth of pipe or vessel port specifically.
Background technique
Common stopper is a taper that has big column at present, in use will make object and isolate from outer air, unlikely leaking outside in pipe or the container, object does not damage, and is preserved, but very difficult being difficult for, and insertion is extracted not very convenient in the mouth of pipe or vessel port.
Summary of the invention
The purpose of this utility model is in order to solve the problem of above-mentioned existence, and provide a kind of and have sealing, insert extract conveniently, and the reducing stopper that can use repeatedly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of reducing stopper, comprise cock body, Joystick, seal ring, its structure is: described cock body by the stiff baseplate in the rigid panel of a center band through hole and a flexible sleeve, strap bolt hole, a center be connected in series form a top, the bottom is that rigid body, perisporium are the cavity body of flexible body, the bottom centre of this cavity body is provided with bolt hole, top center is provided with through hole, its screw footpath D1＜through-hole diameter D2.
Described Joystick is that one one end is a screw rod, and the other end is the connecting body of handle; Screw rod one end end in this Joystick is a worm structure, and the internal thread size of its thread size and cock body bottom bolt hole is complementary, and the other end end is a cylindrical body, the diameter D2 of its cylindrical diameter D3＞cock body top through hole.
Described rigid panel, itself and flexible sleeve surface of contact one side are provided with positioning boss, and this positioning boss diameter is slightly less than casing inner diameter.
Described rigid panel diameter equals the flexible sleeve top diameter.
Described stiff baseplate, itself and flexible sleeve surface of contact one side are provided with positioning boss, and this positioning boss diameter is slightly less than casing inner diameter.
Described stiff baseplate diameter equals the flexible sleeve base diameter.
Described rigid and flexible sleeve pipe 12 is a rubber parts.
The utility model principle is: rigid panel and flexible sleeve, rigidity floor are connected in series, and to constitute a bottom with threaded hole, top band center hole, and bottom, top are rigid body, perisporium is the cock body of flexible body; With stuffing box gland and one one end be that screw rod, the other end are that the Joystick of handle connects to form a kind of reducing stopper.The reducing stopper is inserted in the corresponding mouth of pipe or vessel port, be rotated down Joystick, stiff baseplate moves up, and cock body perisporium pressurized outwards expands, the tensioner mouth of pipe or vessel port, the reducing plug seal mouth of pipe or vessel port.Otherwise rotate up Joystick, stiff baseplate moves down, and cock body perisporium pressurized is eliminated and inwardly resetted, and the reducing stopper unclamps the mouth of pipe or vessel port.
The beneficial effects of the utility model are: 1, compared with prior art, good sealing effect, 2, can adjust the size of stopper circumference, make stopper insert, extract the mouth of pipe or vessel port easily.
