Description

Novel manhole cover for water supply or drainage protective device

Technical field

The utility model relates to well lid field more particularly to a kind of novel manhole cover for water supply or drainage protective devices.

Background technique

In discharge well use process, well lid mostly uses cast iron to be made, and is easy when being impacted by external load because of casting Making defect causes to crack, and jeopardizes personal safety, absorbs impact power and lacks damping, and do not have safeguard procedures inside well body, in people Member is unable to effective protection when dropping, and structure is not reasonable.

Utility model content

The utility model In view of the above shortcomings of the prior art, provides a kind of structurally reasonable novel manhole cover for water supply or drainage Protective device.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of novel manhole cover for water supply or drainage protective device, including protective cover, well lid, rubber shock-absorbing ring, cover seat of manhole, the protection Covering lower part has the taper bucket, and limbers is uniformly distributed inside the taper bucket, and the taper bucket bottom has bottom sheet, has inside bottom sheet Through-hole, protective cover outside have pressure ring, have trapezoidal bulge loop slot inside pressure ring, and the well lid internal symmetry is distributed well lid lid eye, There is trapezoidal bulge loop at the top of the rubber shock-absorbing ring, there is rubber ring inner hole, the cover seat of manhole bottom tool inside rubber shock-absorbing ring There is fixed bottom plate, fixed bottom plate is placed in ground, and cover seat of manhole top has assembling stand, has resettlement groove, assembly inside assembling stand Seat is internal to have water hole.

In the rubber shock-absorbing ring merging resettlement groove, protective cover is placed in resettlement groove, and trapezoidal bulge loop is placed in trapezoidal bulge loop slot Interior, rubber ring inner hole and water hole cooperatively form flow cavity, and the taper bucket is placed in flow cavity, and limbers and flow cavity cooperate, well In lid merging resettlement groove, well lid bottom and protective cover top surface are pressed.

The utility model has the advantages that

Protective cover material is ABS, absorbs impact load and resistant to rust ability is preferable, the taper bucket is taper, inner space It is larger, it circulates convenient for water body, and biggish space can be provided to fall object, it can be uniformly by impact force point when absorbing impact Dissipate, structurally reasonable, trapezoidal bulge loop is placed in trapezoidal bulge loop slot, contact surface be it is trapezoidal, can uniformly bear vibration force and gravity, hold It carries steadily, and rubber shock-absorbing ring material is rubber, it is possible to reduce the vibration force impact that well lid is subject to extends the well lid service life, rubber Glue shock ring is placed in resettlement groove, can be provided covering for the horizontal plane of resettlement groove, be avoided the accumulations such as rainwater from causing to corrode, structure Rationally.
