Abstract
The utility model provides a rubber sealing plug which comprises a sealing cover, a sealing plug body and a fixing hole. A cylindrical piston is arranged at the bottom end of the sealing cover, the fixing hole is formed between the piston and the sealing plug body, the sealing plug body sequentially comprises a rubber sleeve and an outer sleeve from inside to outside, the rubber sleeve and the outer sleeve are both conical, the upper end face and the lower end face of the rubber sleeve and the upper end face and the lower end face of the outer sleeve share the same circle center, the ratio of the outer diameter of the rubber sleeve and the outer diameter of the outer sleeve is 2:1, internal threads are arranged on the inner edge face of the rubber sleeve, and the rotating direction of the internal threads is left. The rubber sealing plug has the advantages that due to the fact that the internal threads on the inner edge face of the rubber sleeve are adopted, the sealing effect of the rubber sealing plug is good, the phenomenon of disengagement in the using process is avoided, the service life of the sealing plug is prolonged, and the safe operation of a machine is ensured.
Description
Technical field
The utility model belongs to rubber seal field, especially relates to a kind of rubber seal plug.
Background technique
The accident that leakage causes happens occasionally, and is greatly endangering people's the security of the lives and property, so sealing gasket is widely used in field of engineering technology.Aspect core warship, its shutdown system does not have black box at present, causes it in use easily to leak, befouling environment, and can make shutdown system normally use, serious time, even can affect the use of warship equipment.Need a kind of Novel sealing component that is used in shutdown system, ensure the normal operation of equipment.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of rubber seal plug, is especially applicable to corrosion-resistant and acid resistant alkali, can effectively prevent that shutdown system from leaking.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of rubber seal plug, comprise sealing cover, sealing plug main body and fixed hole, described sealing cover bottom is provided with cylindrical piston, between described piston and described sealing plug main body, be provided with described fixed hole, described sealing plug main body comprises rubber sleeve, overcoat from inside to outside successively, described rubber sleeve, described overcoat are taper, described rubber sleeve and described overcoat upper and lower end face are the same center of circle, described rubber sleeve external diameter is 2:1 with described overcoat external diameter ratio, described rubber sleeve inner edge surface is provided with internal thread, and the sense of rotation of described internal thread is left-handed.
The height of described piston is greater than the height of fixed hole.
The diameter of described fixed hole is 1cm-2cm, is highly 5cm-6cm.
Described overcoat outside is provided with groove.
Described rubber sleeve, described overcoat and described fixed hole are integrated formed structure.
The beneficial effects of the utility model are: adopt internal thread on rubber sleeve inner edge surface to make rubber seal plug good sealing effect, avoid occurring break-off in using process, increase the working life of sealing plug, ensured the safe operation of machine.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
In figure:
1, sealing cover 2, piston 3, rubber sleeve
4, sealing plug main body 5, groove
Embodiment
Below in conjunction with accompanying drawing, a kind of embodiment of the present utility model is explained.
As shown in Figure 1, a kind of rubber seal plug of the utility model, comprise sealing cover 1, sealing plug main body 4 and fixed hole, sealing cover 1 bottom is provided with cylindrical piston 2, between piston 2 and sealing plug main body 4, be provided with described fixed hole, sealing plug main body 4 comprises rubber sleeve 3 from inside to outside successively, overcoat, rubber sleeve 3, described overcoat is taper, rubber sleeve 3 is the same center of circle with described overcoat upper and lower end face, rubber sleeve 3 inner edge surfaces are provided with internal thread, the sense of rotation of described internal thread is left-handed, described overcoat outside is provided with groove 5, rubber sleeve 3, described overcoat and described fixed hole are integrated formed structure.
Embodiment: rubber seal plug comprises sealing cover 1, sealing plug main body 4, piston 2 and fixed hole, the diameter of described fixed hole is 2cm, is highly 6cm, and the height of piston 2 is 7cm, the height of piston 2 is greater than the height of fixed hole, and rubber sleeve 3 external diameters are 2:1 with described overcoat external diameter ratio.
The working procedure of this example: when use, sealing cover 1 is tightened, and piston 2 moves downward, makes piston 2 contact closely with rubber sleeve 3, reaches the effect of preliminary sealing.Subsequently, finally compress with nut, in the time that nut presses down sealing cover 1, sealing cover 1 pushes the taper mouth of rubber sleeve 3 bottoms, makes rubber deformation, thereby reaches the effect of further sealing.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
