Abstract
The utility model relates to an inspection well cover theft protection device which comprises a well cover engaged with a well head. The utility model is characterized in that the inner side of the well cover is connected with an anti-theft connecting arm through a pivot shaft, more than two knuckles are connected together through the pivot shaft to form the anti-theft connecting arm, and the other end of the anti-theft connecting arm is hinged on the well wall of the inner side of the well head. The utility model uses the anti-theft connecting arm to lead the well cover and the well head to be connected for forming an integrated body, the well cover is not easy to move or reverse, which effectively plays a function of anti-theft, and the anti-theft connecting arm with a T-shaped cross-section is light in weight and strong in bending resistance.
Description
Technical field
The utility model relates to a kind of Cover of inspection well anti-theft device.
Background technology
In the construction of urban road a lot of inspection shafts will be installed, the well lid of inspection shaft is stolen to be present ubiquitous phenomenon, causes the person, vehicle damage accident.Existing iron well lid and well head partial installation are very easily stolen or the displacement of reversing causes dangerous accident, even cause serious car crash, bring about great losses to people.The well lid bad mechanical strength of nonmetals is damaged easily, and the alternative metals well lid uses fully.
Summary of the invention
The purpose of this utility model provides a kind of Cover of inspection well anti-theft device that is used for the metal manhole cover anti-theft.
For achieving the above object, the utility model adopts following technical scheme:
Cover of inspection well anti-theft device described in the utility model comprises the well lid that cooperates with well head, it is characterized in that: the inboard of well lid is connected with antitheft link arm by hinge, antitheft link arm constitutes with upper joint by two that link together by hinge, and the other end of antitheft link arm is hinged on the borehole wall of well head inboard.
The cross section in each joint of the antitheft link arm of above-mentioned formation is a T shape.
After adopting technique scheme, antitheft link arm is connected in one well lid and well head, makes well lid be not easy to be moved or to reverse, and has effectively played antitheft effect, and cross section is that the antitheft link arm of T shape is in light weight, bending resistance is strong.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the cross section view of antitheft link arm;
Fig. 3 is the structural representation of the coupling part of antitheft link arm and well lid.
The specific embodiment
As shown in drawings, Cover of inspection well anti-theft device described in the utility model comprises the well lid 2 that cooperates with well head 1, the inboard of well lid 2 has the hangers 4 that hinge 5 is installed, be connected with antitheft link arm 3 by hinge 5 on the hangers 4, antitheft link arm 3 constitutes with upper joint by two that link together by hinge, and the other end of antitheft link arm 3 is hinged on the borehole wall of well head 1 inboard.The cross section that constitutes each joint of antitheft link arm 3 is a T shape.In order to improve theftproof performance, all adopt antitheft cancellation at hinge on the hangers 4 and the hinge that connects between antitheft link arm 3 each joint.
Well lid 2 and the structure that hangers 4 can adopt casting to become one also can design hangers on a Connection Block 6 separately, and then Connection Block 6 be fixedly mounted on the inboard of well lid 2 with anti-theft bolt or antitheft rivet.Antitheft link arm 3 is identical therewith with the connected mode of well head inwall.
