Abstract
The utility model discloses a cover for a telecommunication inspection manhole. The external periphery of the cover body is provided with a first sealing ring. Because the external periphery of the cover body is provided with the first sealing ring (certainly, a well head is matched), bouncing can not happen when motor vehicles pass through, and the utility model can prevent water and dust. In addition, the bottom of an inspection opening lockhole is provided with a sealing block which is provided with a screw, and a second sealing ring is arranged between a screw cap and the sealing block to ensure the sealing and water and dust prevention of the bottom of the inspection opening lockhole. When the opening lockhole is closed, the screw can be screwed out to clean the opening lockhole, and the utility model has the advantages of convenience and practicability.
Description
Technical field
The utility model relates to a kind of inspection shaft lid, especially a kind of lid of telecommunications manhole
Background technology
The laying of the long distance of telecommunications cable needs establish a bite well every some distances, is convenient to like this check that there is following defective in this aboveground used lid at present, and one, vehicle wheels one be through promptly beating, noise is bigger like this, influences environment; Two, infiltration and foreign material enter in the well easily, like this cable are caused certain harm.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of telecommunications manhole cover, and this telecommunications can make vehicle wheels through not beating and the well head good airproof performance waterproof and dustproof with manhole cover.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of lid of telecommunications manhole, well lid body outward flange is provided with first sealing ring.
Be provided with groove in the middle of the well lid body outward flange facade, first sealing ring is embedded in the groove.
The well lid body is provided with at least one and checks open keyhole (it is used to be used to open well lid), check that the open keyhole base diameter enlarges, be provided with one again and enlarge the sealing block that the back size is complementary with checking the open keyhole base diameter, the sealing block fixing seal is inserted in checks that open keyhole base diameter enlarged (does not influence like this and unblanks, top can the conflict of sealing block checked the space that is used to unblank of open keyhole bottom,), sealing block is provided with tapped through hole again, one screw screws in the tapped through hole from the sealing block bottom, be provided with second sealing ring between the nut of described screw and sealing block bottom contact surface, like this can be checking the sealing fully of open keyhole bottom, waterproof, dustproof.
Check that the open keyhole top plugs one " T " font sealing-plug, the height that " T " font sealing-plug exposes is identical with the decorative pattern height of cap surface projection.
The cross section of sealing block is trapezoidal, checks that open keyhole base diameter enlarged inner wall shape and sealing block are complementary.
The beneficial effects of the utility model are: because well lid body outward flange is provided with first sealing ring (well head need cooperate certainly), motor vehicle just can not beated through out-of-date like this, and waterproof and dustproof again, check that again the open keyhole bottom is provided with sealing block, and be installed with screw on the sealing block, be provided with second sealing ring between nut and sealing block, can guarantee to check open keyhole bottom water-tight, dustproof like this, during as the open keyhole obturation, can screw out screw cleaning open keyhole, convenient and practical.
