Abstract

The utility model relates to a manhole used for solving the technical problems that the existing manhole cover is easily lost, the existing manhole cover is easy to turn over to hurt people, etc. In order to solve the technical problems, the utility model comprises a manhole cover and a manhole base. The utility model is characterized in that a hinge ear is arranged on the manhole cover, the manhole base is provided with two hinge ear bases, and the hinge ear is buckled between the two hinge ear bases. The hinge ear and the hinge ear bases are provided with through holes, and a rivet connects the manhole cover and the manhole base together by passing through the through holes. The manhole cover can be efficiently prevented from being stolen because the utility model adopts the structure that the rivet connects the manhole cover and the manhole base together, and the manhole cover and the manhole base are fixed to the ground. Therefore, the injury to vehicles and people is avoided. In addition, the manhole cover is covered on the manhole base so the manhole cover can not turn over to hurt people owing to the structure adopted by the utility model that the cover is big while the base is small and the peripheral edge of the cover is provided with a circle of flanges.

Description

A kind of inspection shaft

Technical field

The utility model relates to a kind of inspection shaft, specifically to having a kind of improvement of inspection shaft now.

Background technology

Inspection shaft quantity on the road is a lot of now, uses very extensive.But existing inspection shaft lid is often stolen, causes a lot of vehicles, personnel casualty accidents, endangers very big; In addition, existing inspection shaft lid is little, seat is big, and lid is to be embedded in basement and the seat by a groove on the seat, and, distortion bigger than normal when lid or when not buckling well causes the upset of inspection shaft lid to hurt sb.'s feelings easily or send snap snap the sound.

Summary of the invention

The utility model is for the easy upset technical problem such as hurt sb.'s feelings of losing easily of solving that existing inspection shaft lid exists and inspection shaft lid.

In order to solve the problems of the technologies described above, the utility model comprises inspection shaft lid and inspection shaft seat, it is characterized in that: cover at inspection shaft and be provided with the hinge ear, the inspection shaft seat is provided with hinge ear seat, the hinge earclip is between two hinge ear seats, have through hole on hinge ear and the hinge ear seat, rivet passes through hole the inspection shaft lid is linked together with the inspection shaft seat.

The external diameter of described inspection shaft lid has a circle flange greater than the external diameter of inspection shaft seat on the neighboring of inspection shaft lid.

Thickness 〉=the 10mm of described inspection shaft lid.

The reinforcing rib of described inspection shaft lid be " ^*" the shape distribution.

The utlity model has following advantage and good effect: 1, because the utility model has adopted said structure, inspection shaft lid and inspection shaft seat are linked together by rivet, fix on the ground, can prevent effectively stolen, thereby avoid vehicle and personnel are damaged; 2, lid is big, the little this structure of seat because the utility model has adopted, and a circle flange is arranged on the neighboring of lid, and the inspection shaft lid is buckled in can not overturn on the inspection shaft seat hurts sb.'s feelings; 3, because the utility model enlarged in thickness has improved supporting capacity; 4, because covering the distribution of reinforcing rib, the utility model inspection shaft changed " well " font distribution in the past, and adopted " ^*" the shape distribution, thereby stronger to the support at inspection shaft lid center.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.
