Description
Technical field
This utility model relates to a kind of inspection hole and seals lid, belongs to mechanical field.
Background technology
In building, plastic drain-pipe checks that hole is commonly used dismountable threaded plastics inspection cover and carried out sealing anti-leak; in use aging lax due to working of plastics and rubber blanket; along with the prolongation of the time of use usually there will be drainage; the leakage of sewage has a strong impact on cleaning and uses with normal; therefore check that effective anti-leak in hole is very concern in people's daily life, be also one of key quality problem in water supply and sewage work.
Summary of the invention
This utility model provides a kind of inspection hole and seals lid, for the purpose reaching anti-leak.
The technical solution of the utility model is: a kind of inspection hole seals lid, including inspection cover 1, rubber seal 2, described inspection cover 1 is made up of groove upper surface 12, groove cylinder 13, groove lower surface 14 and the groove conical surface 15 with internal thread hole 11 and sealed groove, described sealed groove；
Rubber seal 2 is placed at the sealed groove of described inspection cover 1, internal thread hole 11 reaches to be connected and fastening effect with nose end head cylindrical thread face 32 cooperation of inspection, and rubber seal 2 is adjacent to groove upper surface 12, groove cylinder 13 by the groove lower surface 14 of inspection cover 1 and the pushing of the groove conical surface 15 and checks nose end end surface 31 and check nose end head cylindrical thread face 32.
The cross section of described rubber seal 2 is the hollow annular body of L-type.
Operation principle of the present utility model is:
In the sealed groove of the plastics inspection cover 1 that rubber seal 2 is placed into, then it is screwed to check on nose end head thread face 32, groove lower surface 14 and the groove conical surface 15 produce the extruding force of both direction to rubber seal 2, promote rubber seal 2 to be extruded fill full inspection cover sealed groove and check nose end end surface 31 and check the bore that nose end head cylindrical thread face 32 is constituted, reach effectively to seal the purpose of anti-leak.
The beneficial effects of the utility model are: simple in construction, easy to use；Reach the purpose of effective sealing anti-leak.
