Abstract

The utility model relates to a colorful and multifunctional rubber plastic manhole cover with environment protecting function, and belongs to a manhole cover. Only parts of a manhole cover seat or the inner part of the manhole cover are provided with steel skeletons, and other parts of the manhole cover seat and the inner part of the well cover all use rubber plastic materials as stuffing. The reuse value is low, and the utility model is not easy to steal. The rubber plastic materials are enwrapped outside the manhole cover seat and the manhole cover, the elasticity is large, and the damping performance is good. Different permanent colors can be coated on the utility model, and a certain color is coated on the manhole cover with a certain purpose, which causes people to clearly see manholes. The manhole cover is formed by combining the steel skeletons and the rubber plastic materials, and the impact force resistant intensity is high. The utility model can have damping and noise reducing functions, and the colors beautify cities, which generates good effect.

Description

How the environment-friendly type rubber and plastic is colorful covers with inspection shaft

The utility model relates to a kind of inspection shaft lid, and how particularly a kind of environment-friendly type rubber and plastic is colorful covers with inspection shaft.

At present, be installed in the inspection shaft lid of road, be stamped a manhole cover base, a well lid is arranged on the manhole cover base as the inspection shaft of sewer, cable etc.This manhole cover base, well lid are all as a whole to be made by cast iron, owing to be that metal is made, regeneration is worth higher, and very easily stolen molecule is stolen; Owing to be that cast iron is made, corrosion damages easily, and damping property is bad, and color is single, even brush pigment thereon, also will be worn away soon, determines this well lid to have bigger fragility by the character of cast iron, and easily brisement damages under action of gravity.

The purpose of this utility model provides a kind of difficult colorful how lid with inspection shaft of environment-friendly type rubber and plastic of being stolen, being difficult for brisement.

The purpose of this utility model is achieved in that manhole cover base and well lid have a reinforcing bar, and reinforcing bar is wrapped with rubber-plastics material.

Handle is arranged on the well lid, and the upper surface of handle and well lid is flat, and groove is arranged at the handle bottom.

Reinforcing bar is physical form identical with the well lid shape with manhole cover base or the mesh shape identical with the well lid shape with manhole cover base.

Owing to adopted such scheme, have only the part reinforcing bar in manhole cover base or the well lid, other position all is filler with the rubber-plastics material, the value of regeneration is relatively low, has been unworthy that promptly the robber steals, so be difficult for being stolen; Be wrapped with rubber-plastics material at manhole cover base and well lid, the elasticity of rubber-plastics material itself is bigger, elastic deformation is bigger, when its product that is processed to form is applied bigger impact force, this product is difficult for brisement to be damaged, simultaneously because the elastic deformation of product is bigger, damping property is good, and process in this product process, in raw material, add different pigment, can produce the product of different color, the color of this coloured prod is permanent color, give the well lid of a certain purposes with a certain color, people are come into plain view to inspection shaft, reached the purpose of this utility model.This inspection shaft lid has adopted the perfect combination of reinforcing bar and rubber-plastics material, makes the inspection shaft lid that shock-resistant intensity of force promptly be arranged, and has better elastic again, makes the inspection shaft lid can play the effect of vibration damping, sound insulation, its colour has beautified the city, produced the meaning less than effect.

Be described further in conjunction with the embodiments with reference to the accompanying drawings below.

Fig. 1 is the first example structure figure of the present utility model.

Fig. 2 is the sectional structure chart of figure.

Fig. 3 is the second example structure figure of the present utility model.

Fig. 4 is the 3rd example structure figure of the present utility model.

Fig. 5 is the 4th example structure figure of the present utility model.

Embodiment 1: among Fig. 1, Fig. 2, the manhole cover base 4 of inspection shaft and well lid 1 have a reinforcing bar 6, reinforcing bar 6 is wrapped with rubber-plastics material 7, there is recessed groove of a week upper end of manhole cover base 4 inner rings, well lid 1 is installed in the groove and with manhole cover base 4 upper edge surface and puts down, handle 2 is arranged on the well lid 1, and handle 2 is flat with the upper surface of well lid 1, and groove 3 is arranged at handle 2 bottoms.Manhole cover base 4 and well lid 1 are circular, and a circumferentially outer limit of protruding is arranged at manhole cover base 4 bottoms, is connected with reinforcing rib 5 between limit to the portion of manhole cover base 4 of protruding, and reinforcing bar 6 is the physical form identical with well lid 1 shape with manhole cover base 4.

Embodiment 2: among Fig. 3, manhole cover base 4 is square, one groove is arranged on the side of manhole cover base 4, well lid 1 is circular, one protrusion is arranged on the side of well lid 1, protrusion is inserted in the groove of manhole cover base 4 on the well lid 1, with connecting pin 8 well lid 1 is connected with manhole cover base 4, and reinforcing bar 6 is the mesh shape identical with well lid 1 shape with manhole cover base 4.Other and embodiment 1 omit together.

Embodiment 3: manhole cover base 4 and well lid 1 are circle, and other and embodiment 2 omit together.

Embodiment 4: manhole cover base 4 and well lid 1 are rectangle, and many row rectangular opening, i.e. gratings are arranged on the well lid 1.Other and embodiment 2 omit together.
