Abstract

The utility model discloses a burglary-preventing quakeproof well cover, the well cover (1) is connected with the well base (3) by a parallel pin (2) which is pushed into the place of the pinhole (8) of the well base by spring (4) tension that makes the well cover (1) and the well base (3) become an integral whole and un-disassembled, thereby preventing burglary. In addition, the junction of the well cover (1) and the well base (3) is the inclination which effectively prevents the well cover (1) from displacing in the well base (3) and the closeness between them is good enough to reduce noise. Radian exists at the junction of the well cover (1) and the well base (1), the opening angle of the well cover is from 120 degrees to 135 degrees. The utility model has the advantages that structure is simple and cost is low, the function of preventing burglary is powerful, shaking noisy could be reduced, maintenance is convenient, and has safety alarming function when opened and closed, has the value of popularizing widely.

Description

A kind of antitheft, shockproof well lid

Technical field

The utility model belongs to a kind of pipeline, sewage, tap water or cable check well well lid of being used for, and relates in particular to a kind of antitheft, shockproof well lid.

Background technology

In various manhole uses, the stolen phenomenon of well lid often taking place, brings very big harm and loss to the country and people at present.The well lid that has now come into operation in addition is because of a variety of causes, when vehicle from well lid by the time, send bigger vibrating noise, along with the continuous increase of manhole kind and quantity, this noise pollution is serious day by day; And because silt etc. stop up the gap of well lid and walling crib, cause the opening difficulty during maintenance.The someone proposes some ways such as the patent No. is CN03121738.9 " a safe theft-proof well cover walling crib " in order to address the above problem for this reason, the patent No. is CN03269543.8 " novel antitheft well cover " etc., though play certain antitheft effect, also have deficiencies such as complex structure.

Summary of the invention

The purpose of this utility model provides a kind of novel anti-theft, shockproof well lid.

The utility model is achieved in that a kind of antitheft, shockproof well lid, is made up of well lid, straight pin, spring, reinforcing rib and standing screw; The connecting hole that one mounting spring and garden pin are arranged on the well lid and has two cylinder pin holes on the supporting well seat of this well lid.Well lid adopts straight pin to connect with the well seat, utilize the tension force of spring that straight pin is pushed in the well seat cylinder pin hole, well seat and well lid are connected as a single entity, non-dismountable, thereby reach antitheft purpose: the well seat is that the inclined-plane combines with the bonding surface of well lid in addition, pin connects and the inclined-plane has effectively prevented the displacement of well lid in walling crib in conjunction with design, and closure is good between well lid and the well seat, thereby reduces vibrating noise; When well lid is closed and between well seat cushion cap one gap is arranged, the unlatching that has guaranteed well lid when checking freely; Well lid and well seat pin connection place, the opening angle of well lid can reach between 120 °～135 °, and the one side of digging is painted sign, can also be as a kind of construction caution notice.

Antitheft, shockproof well lid of the present utility model has the following advantages: 1. simple in structure, cost is low; 2. anti-theft feature is strong; 3. can reduce automobile through out-of-date vibrating noise.4. maintenance is convenient, reduces labour intensity; The Security alert effect is arranged during 5 unlatchings.
