Abstract
The invention discloses an anti-theft manhole cover which comprises a cover and a base, wherein the cover is articulated with one side of the base; a connecting shaft which is arranged on the bottom surface of the cover and is parallel to the cover is articulated between the cover and the base; two open slots which are arranged in parallel and can be blocked into the connecting shaft of the cover are arranged at the corresponding positions of the base; the striking directions of the open slots are along the horizontal direction; openings of the open slots are arranged towards the interior of the base; the upper slot side and the lower slot side of each open slot are respectively provided with a locating pin, and the locating pins are used for locking the openings of the open slots and enabling the upper slot side to be communicated with the lower slot side. According to the anti-theft manhole cover, the hinge joint part between the cover and the base is internally hidden, so that the anti-theft manhole cover has good anti-theft function on the one hand, and avoids the ground being scratched by the exposed hinge joint part on the other hand. The cover is embedded into the base, so that the cover is avoided jumping, and the abnormal sound is further avoided.
Description
Technical field
The present invention relates to a kind of cellar for storing things well protector, particularly a kind of anti-stealing manhole cover.
Background technology
Along with increasing of city vehicle, the various well lids such as the conventional electric power manhole cover of installing and using in urban road answer design reasons through after the rolling for a long time of vehicle, easily cause that well lid subsides, sinking, sound, beat, the problem such as stolen.The tradition well lid is due to lid and base or be split-type structural, or is that hinged place is external, and hinged place just becomes a weak spot like this, is easy to generation and starts with and stolen from hinged place.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and a kind of a kind of anti-stealing manhole cover that prevents that well lid is stolen is provided.
A kind of anti-stealing manhole cover, include lid and base, described lid and base one side are hinged, hinged for be provided with the connecting axle paralleled with lid in the bottom surface of lid between lid and base, be provided with two open slots arranged side by side that can snap in the lid connecting axle in the corresponding position of base, the trend of described open slot is along horizontal direction, the opening of open slot, towards the inside of base, is provided with the alignment pin of upper and lower two trough rims of communication for the open slot opening is pinned on two trough rims up and down of open slot.
Adopt this lid and the articulated manner of base, in use, only need take away the alignment pin that locks in trough rim, can realize removing and installing between lid and base, owing to being built-in hinged, therefore can play anti-theft function preferably, in the time of also can avoiding uncapping, due to the situation appearance on the hinged external lid brought and hinge axis scratch ground simultaneously.
Described lid is whole being embedded in the middle of base when covering, between lid and base, adopt buckle to carry out sealed, be provided with several buckle fasteners on the inwall of base, the corresponding position of the medial surface of lid be provided with base inner wall on the buckle movable part that is used in combination of draw-in groove.
The well lid of this structure, be to be embedded in base due to lid when sealed, by buckle, lid is connected with base, just can make lid and base be integrative-structure, so just can avoid lid to beat, thereby produce abnormal sound.
Described buckle movable part is to be the resilient locking arm of integrative-structure with lid, the boss of described buckle fastener for arranging on base.
On lid, be provided with for opening the irregularly-shaped hole of lid.
Irregularly-shaped hole is set on lid, on opening, needs to adopt the ripping bar be complementary with irregularly-shaped hole to be opened, thereby can farthest avoid this to advance the stolen of lid.
Be provided with dovetail groove on the inside wall of base, rubber pad is set in dovetail groove, described lid contacts with rubber pad when covering.
Dovetail groove is set on base, and rubber pad is set in dovetail groove, make lid contact with rubber pad, can effectively prevent that like this lid and base from clashing into and the noise of generation.
Hinged side at base and lid is provided with one along the inner small boss extended of end Cuo, be provided with a vertical movable latch in the corresponding position of lid, the vertical movable latch junction of lid relatively swings, and can on the small boss face of base, slide, the height of vertical movable latch is equal to or less than the air line distance of vertical movable latch vertical type capping to base small boss place, to guarantee that lid and base can't be closed during in obliquity in vertical movable latch, when vertical movable latch, lid and base can be in closure states during in vertical position.
Between the base of well lid and lid, this structure is set, when the needs close cap, set vertical movable latch, pass upper cover that so just can be smooth, when in the course of the work, because vertical movable latch is in heeling condition, once the lid accident, fall like this, due to the state of vertical movable latch in tilting, therefore can play the effect that prevents lid and base closure, thereby improve operating personnel's safety.
In sum, the present invention's following advantage compared to existing technology:
Anti-stealing manhole cover of the present invention, because the hinged place of lid and base is built-in, can play good anti-theft function on the one hand, can overcome on the other hand the situation generation that the scratch ground of bringing is exposed in hinged place.And due to lid is embedded into to base, therefore can avoid lid to beat, thereby produce abnormal sound.Irregularly-shaped hole is set on lid, making to need special tool by the open cap period of the day from 11 p.m. to 1 a.m, therefore can play anti-theft function, and the dovetail groove that is built-in with rubber pad is set on base, therefore also can reduce the generation of noise simultaneously.The present invention has also adopted the unexpected closing device of this anti-lid, has safe and reliablely, improves operating personnel's safety.
