Abstract
The utility model relates to a well lid elastic locking mechanism which comprises a well lid body and a walling crib for bearing and placing the well lid body. The lower bottom surface of the well lid body is provided with a plurality of elastic arms; the walling crib is also correspondingly provided with bumps, grooves or concave holes for buckling the elastic arms; and convex blocks are arranged between the elastic arms and the lower bottom surface of the well lid body. According to the well lid elastic locking mechanism provided by the utility model, the lower bottom surface of the well lid body is provided with a plurality of the elastic arms and the walling crib is also correspondingly provided with the bumps, the grooves or the concave holes for buckling the elastic arms, and thus, the elastic arms on the well lid body are clamped by the bumps, the grooves or the concave holes on the walling crib, so that when vehicles pass through the well lid body, the well lid body cannot be opened under the action of an impulsive force to influence running safety of the vehicles.
Description
technical field:
The utility model relates to a kind of well lid elastic locking mechanism.
background technology:
Well lid includes the well lid body and for bearing the walling crib of well lid body, it is extensively as the artificial passway of keeping in repair of underground water, the electricity etc. such as municipal administration, community, but at the well lid of pavement usage owing to often there being vehicle to pass through, easily cause beating of well lid, often well lid can be opened under the effect of larger impulse force, outside well head is exposed to, cause danger to travelling of vehicle.
summary of the invention:
The purpose of this utility model is to provide a kind of well lid elastic locking mechanism, and this well lid elastic locking mechanism is not only simple in structure, reasonable in design, and is conducive to avoid beating of well lid.
The utility model well lid elastic locking mechanism, include the well lid body and for bearing the walling crib of well lid body, it is characterized in that: described well lid body bottom surface is provided with several elastic arms, go back correspondence on described walling crib and be provided with projection, groove or the shrinkage pool that fastens elastic arm, between elastic arm and well lid body bottom surface, be provided with protruding block.
Above-mentioned elastic arm is curved, c-shaped or S-shaped.
The utility model well lid elastic locking mechanism is provided with several elastic arms by described well lid body bottom surface, go back corresponding projection, groove or the shrinkage pool that fastens elastic arm that be provided with on described walling crib, elastic arm on the well lid body is lived by the projection on walling crib, groove or shrinkage pool clamping stagnation, thereby allow the well lid body vehicle through out-of-date can be due to the effect of impulse force under and raised, and affect the driving safety of vehicle.
the accompanying drawing explanation:
Fig. 1 is the organigram of looking up of the present utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the A-A sectional drawing of the another kind of embodiment of the utility model.
the specific embodiment:
The utility model well lid elastic locking mechanism, include well lid body 1 and the walling crib 2 for bearing the well lid body, and described well lid body 1 bottom surface is provided with several elastic arms 3, goes back corresponding projection, groove or the shrinkage pool 4 that fastens elastic arm 3 that be provided with on described walling crib 2.
For elastic arm 3 can be blocked by projection, groove or shrinkage pool 4, and can not allow elastic arm 3 be too near to well lid body 1 bottom surface due to elastic arm 3 elasticity own, between above-mentioned elastic arm 3 and well lid body 1 bottom surface, be provided with protruding block 5
.this protruding block 5 is located on elastic arm 3 or well lid body 1 bottom surface all can.This protruding block 5 can make elastic arm 3 slip into smoothly in groove or shrinkage pool 4, or protruding block 5 can make elastic arm 3 slip over smoothly projection 4, in projection 4 belows.
In order to design the use needs, above-mentioned elastic arm is curved, c-shaped or S-shaped.
In fact be provided with elastic arm 3 and the projection 4 of 3-5 group on a well lid body 1.
More reasonable in order to design, bottom, above-mentioned support panel outer end is provided with in order to the boss 6 that hooks firm ground.
For anti-skidding, above-mentioned concave station 203 is provided with groove 205, is equipped with rubber ring 206 in described groove.
Cylindricality circle 201 cross sections be circular or rectangle all can, support panel 202 is circular or also all can of rectangle.
The utility model well lid elastic locking mechanism is provided with several elastic arms by described well lid body bottom surface, go back corresponding projection, groove or the shrinkage pool that fastens elastic arm that be provided with on described walling crib, elastic arm on the well lid body is lived by the projection on walling crib, groove or shrinkage pool clamping stagnation, thereby allow the well lid body vehicle through out-of-date can be due to the effect of impulse force under and raised, and affect the driving safety of vehicle.When the well lid body will be opened, need well lid to be separated with walling crib with under the effect of crowbar.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
