Abstract

A lockable well cover is provided, which relates to a well of the underground facility. The lockable well cover with a simple structure is provided aiming at hidden danger that the existing well cover directly put on a well seat which can be moved or taken off to make the well have no cover. The technical proposal adopted is that the utility model comprises a well seat (1) in an inner step shape and a well cover (4). The utility model is characterized in that an L-shaped lock hook (6) is arranged in a protruding supporting seat (6) with holes in one side cover surface of the well cover (4), and a groove is arranged outside the corresponding side cover surface, a lug with holes and a supporting seat (2) with holes of the well seat (1) arranged outside the other cover surface of the well cover (4) are assembled together with an axle pin (3).

Description

The inspection shaft lid that can lock

One, technical field

The utility model relates to a kind of underground facility, the inspection shaft that especially can lock lid.

Two, background technology

At the urban sewage pipeline, or the underground facilities such as Gas Pipe, power line, connection that are provided with, in order to install or the inspection shaft that is provided with easy to maintenance.Extensively adopt the inspection shaft lid directly to be placed on the inspection shaft seat at present, exist the artificial inspection shaft of removing and cover, or take away, cause the inspection shaft uncovered, form unsafe hidden danger.

Three, summary of the invention

The purpose of this utility model provides a kind of simple in structure, the inspection shaft lid that can lock.

The technical scheme that the purpose of this utility model adopted is, the inspection shaft seat of step and inspection shaft lid in including, it is characterized in that having in the projection bearing with holes in the end cap end face of inspection shaft lid, be equipped with outside L type lock hook with holes, the corresponding lid end face fluted with pin, corresponding another end cap of inspection shaft lid has the bearing with holes of microtia with holes and inspection shaft seat outward, is assembled together with pivot pin.

The utility model, the end of L type lock hook are the hole that slope mouth, the other end pass the inspection shaft lid and are positioned at outer groove.

The utility model, with the pivot pin rotation along the bearing of inspection shaft seat of inspection shaft lid, one end of L type lock hook is the slope mouth during to the interior step of inspection shaft seat, can rotate along the pin in the bearing of inspection shaft lid when closing, fall at last under the interior step of inspection shaft seat, lock by means of gravity L type lock hook is vertical; Open inspection shaft when lid, the other end of L type lock hook is outwards dialled, make that end of L type lock hook get out of the way the interior step of inspection shaft seat, open the inspection shaft lid then.

The utility model compared with prior art, and is simple and compact for structure, and fabrication and installation are convenient, opens and opens and closes flexibly, effectively avoids the people for bringing characteristics such as hidden danger.
