Abstract
The utility model discloses a manhole cover, which comprises a base and a cover, wherein the cover is hinged to one side of the base, the cover is integrally embedded into the base when being covered, the cover and the base are locked through a clamp buckle, a plurality of clamp buckle fixing elements are arranged on the inner wall of the base, and clamp buckle moving elements matched with clamp grooves formed in the inner wall of the base to be used are arranged in corresponding positions of the inner side surface of the cover. The manhole cover provided by the utility model has the advantages that the cover is embedded into the base, so the abnormal sound caused by cover jumping can be avoided. Meanwhile, a special-shaped hole is formed in the cover, and a special tool is needed when the cover needs to be opened, so an antitheft effect can be reached. A dovetail groove with a built-in rubber pad is formed in the base, so the noise generation can also be reduced. Meanwhile, a hinging part of the cover and the base is hidden, on one hand, a good antitheft effect can be reached, and on the other hand, the occurrence of ground scratch conditions can be avoided.
Description
Technical field
The utility model relates to a kind of cellar for storing things well protector, particularly a kind of well lid.
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.Tradition well lid abnormal sound and breakage are because well lid capping and base employing latch are fixed, at motor vehicles, through out-of-date Fixed latches, easily become flexible and skid off, well lid capping and base cannot fixedly secure and produce vibrations, and under long-term the rolling of vehicle, well lid vibrations aggravation is sent abnormal sound and is even out of shape and subsides.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provide a kind of, prevents that well lid from producing abnormal sound, the well lid of beating.
A kind of well lid, include base and lid, described lid is hinged on a side of base, described lid is whole being embedded in the middle of base when covering, between lid and base, adopt buckle to carry out sealed, on the inwall of base, be provided with several buckle fasteners, 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, because lid is to be embedded in base when sealed, is connected lid by buckle with base, just can make lid and base be integrative-structure, so just can avoid lid to beat, thereby produces 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 matching with irregularly-shaped hole to open, thereby can farthest avoid this to enter the stolen of lid.
On the inside wall of base, be provided with dovetail groove, 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, lid is contacted with rubber pad, can effectively prevent that like this lid and base from clashing into and the noise of generation.
Hinged for be provided with the connecting axle paralleling with lid in the bottom surface of lid between lid and base, in the corresponding position of base, be provided with two open slots arranged side by side that can snap in lid connecting axle, 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 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 good anti-theft function, in the time of also can avoiding uncapping, due to the situation appearance on the hinged external lid bringing and hinge axis scratch ground simultaneously.
Hinged side at base and lid is provided with one along the inner small boss extending of base, in the corresponding position of lid, be provided with a vertical movable latch, the vertical movable latch relatively junction of lid swings, and can on the small boss face of base, slide, the height of vertical movable latch is equal to or less than vertical movable latch vertical type capping to the air line distance at base small boss place, to guarantee that lid and base cannot 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 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 lid, surprisingly 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 utility model following advantage compared to existing technology:
Well lid of the present utility model, due to lid is embedded into base, therefore can avoid lid to beat, thereby produces 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 simultaneously, 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 that the hinged place of lid and base is built-in, can play good anti-theft function on the one hand, the situation that can overcome on the other hand the scratch ground of bringing occurs.The utility model has also adopted the unexpected closing device of this anti-lid, has safe and reliablely, improves operating personnel's safety.
