Abstract
The utility model relates to a plugging device, including rubber disc chock plug, the centre of rubber disc is equipped with the through -hole, rubber disc both sides all are equipped with circular recess even annular distributes and has rather than inner wall assorted kicking block in the recess, also the annular is evenly embedded in the through -hole has rather than inner wall assorted connecting block, the kicking block with couple together through the elastic component between the connecting block, the chock plug is the toper setting the outer wall of chock plug is equipped with the external screw thread, the inner wall of connecting block be equipped with with this external screw thread assorted internal thread, the chock plug screw in can strut in the connecting block the rubber disc makes it hug closely pipe inner wall and realizes the shutoff. The beneficial effects of the utility model are that: in can installing the pipeline of needs jam rapidly, the dismouting is convenient, improves work efficiency.
Description
Technical field
This utility model relates to pipe fitting, is specifically related to a kind of water pipe block head.
Background technology
Before the related works such as pipeline maintenance or increase branch road, it is necessary to pipeline is blocked, now needs to use block head.Existing block head is complicated due to structure, it is necessary to take a long time to get lodged in pipeline block head, and poor sealing, usually it also occur that leakage phenomenon.
Utility model content
In sum, for overcoming the deficiencies in the prior art, technical problem to be solved in the utility model is to provide
The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of plugging device, including rubber disc chock plug, the centre of described rubber disc is provided with through hole, described rubber disc both sides are equipped with circular groove, in described groove, uniform annular spread has the jacking block matched with its inwall, in described through hole, also annular is uniformly embedded with the contiguous block matched with its inwall, is coupled together by elastic component between described jacking block and described contiguous block；
The tapered setting of described chock plug, the outer wall at described chock plug is provided with external screw thread, and the inwall of described contiguous block is provided with the female thread matched with this external screw thread, can strut described rubber disc and make it be close to inner-walls of duct realization closure in the described chock plug described contiguous block of screw-in.
Further, described elastic component is spring.
Further, described jacking block is circular arc strip.
Further, described contiguous block is circular arc strip.
The beneficial effects of the utility model are: can being installed to rapidly in the pipeline needing blocking, it is convenient to dismount, and improve work efficiency.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the schematic diagram of chock plug.
In accompanying drawing, the list of parts representated by each label is as follows:
1, rubber disc, 2, chock plug, 3, through hole, 4, jacking block, 5, contiguous block, 6, elastic component.
Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature being described, example is served only for explaining this utility model, is not intended to limit scope of the present utility model.
As Figure 1-3, a kind of plugging device, including rubber disc 1 and chock plug 2, the centre of described rubber disc 1 is provided with through hole 3, described rubber disc 1 both sides are equipped with circular groove, in described groove, uniform annular spread has the jacking block 4 matched with its inwall, it is preferred that: described jacking block 4 is in circular arc strip.In described through hole 3, also annular is uniformly embedded with the contiguous block 5 matched with its inwall, it is preferred that: described contiguous block 5 is in circular arc strip.Coupled together by elastic component 6 between described jacking block 4 and described contiguous block 5, it is preferred that: described elastic component 6 is spring.
The described tapered setting of chock plug 2, outer wall at described chock plug 2 is provided with external screw thread, the inwall of described contiguous block 5 is provided with the female thread matched with this external screw thread, and described chock plug 2 screws in and can strut described rubber disc 1 in described contiguous block 5 and make it be close to inner-walls of duct to realize closure.
When needing blocking pipe, plugging device is put into pipeline, chock plug 2 is screwed in again, owing to chock plug 2 is arranged in certain tapering, along with the lasting screw-in of chock plug 2 between described contiguous block 5, chock plug can strut contiguous block 5, contiguous block 5 compression elastic piece 6 made, thus outside support block 4, the final softened change of rubber disc 1 is big, the outer wall of rubber disc 1 is close to inner-walls of duct, it is achieved the closure of pipeline.When removal plugging device, screw off chock plug 5.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
