Description

Press auto-lock and have theftproof well lid of point of application of force

Technical Field

The invention relates to the technical field of well lids, in particular to an anti-theft well lid which is self-locking by pressing and provided with a force application point.

Background

The sewer is as the pipeline of handling waste water and domestic sewage, be convenient for arrange waste water and domestic sewage to fixed place through the sewer pipeline and carry out centralized processing, be favorable to the environmental protection, the well lid that is everywhere visible on the road surface is then installed in the sewer exit, prevent that people or object from falling, because the well lid is generally made by steel, so often someone steals the well lid, sell the waste product recycle bin, trade the interests, and because present well lid is more level, do not exert oneself well, the staff can only remove the well lid with special instrument at the during operation, comparatively loaded down with trivial details.

For example, application number CN201720565705.7 discloses split type polymer well lid convenient to maintenance, which comprises an upper cover, the upper cover is established on the boss of well base inner wall, the boss below is equipped with annular fixture block, be equipped with the well grate on the annular fixture block, be equipped with the steel mesh on the well grate, evenly distributed has the iron sheet of locating hole between the steel mesh, annular fixture block below is equipped with the stopper, be equipped with the bedplate on the stopper, be equipped with the iron plate that has the base on the bedplate, be equipped with the spacer pin in the base, the spacer pin uses with the bracing piece bottom cooperation, the top of bracing piece is passed the well grate and is supported in the upper cover bottom, the stopper below is equipped with the locating piece, be equipped with the drain bar on the locating piece, be equipped with the baffle through the pivot on the outlet. According to the split type polymer well lid with the compact structure and the convenience in maintenance, the weight born by the upper lid in the vehicle rolling process can be effectively dispersed through the arrangement of the supporting rods, the structure is simple, and the use is convenient; because the split type structure of bracing piece, base and upper cover for whole well lid simple structure, simple to operate.

The above patent of the invention has the following problems in the using process:

this patent does not have the mechanism of auto-lock theftproof when using, is difficult to prevent that lawless persons from stealing the well lid to in daily maintenance process, do not have the point of application of force that can be used for removing the well lid, increase the degree of difficulty for the construction operation.

For example, application No. CN201720546072.5 discloses that the present invention provides a manhole cover, comprising: the inner well cover comprises a first side surface and a second side surface opposite to the first side surface; the clamping part is arranged on the first side surface of the inner well lid and has a first state of extending out of the outer edge of the inner well lid and a second state of retracting to the outer edge of the inner well lid; the transmission part penetrates through the inner well cover, the first end of the transmission part is connected with the clamping part, and the second end of the transmission part is arranged on the second side face of the inner well cover so as to drive the clamping part to be in a first state and a second state. The technical scheme of the invention effectively solves the problem that the well lid in the prior art is frequently stolen.

this patent has anti-theft mechanism when using, however, this patent does not have the point of application of force who is used for removing the well lid equally, and operating personnel advances inconveniently when the operation, is difficult to remove the well lid, has increased the operation degree of difficulty.

Based on the two comparison files and the problems existing in the existing product, the inventor provides the anti-theft well lid which is self-locking by pressing and has a force application point to solve the problems.
