Abstract
The invention discloses a kind of anti-stealing manhole cover, include lid and base, described lid is hinged with base side, hinged between lid and base is that the bottom surface of lid is provided with the connecting shaft paralleled with lid, it is provided with two open slots arranged side by side that can snap in lid connecting shaft 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 for upper and lower two trough rims of communication pinning open slot opening on two trough rims up and down of open slot.The anti-stealing manhole cover of the present invention, because lid is built-in with the hinged place of base, on the one hand can play good anti-theft function, and the situation that the scratch ground brought is exposed in hinged place on the other hand can be overcome to occur.And due to lid is embedded into base, lid therefore can be avoided to beat, thus producing abnormal sound.
Description
Technical field
The present invention relates to a kind of cellar for storing things well preventer, particularly a kind of anti-stealing manhole cover.
Background technology
Increasing with city vehicle, the various well lid such as conventional electric power manhole cover installed and used in urban road should
Design reasons after the rolling for a long time of vehicle, easily cause well lid subside, sink, sound, beat, stolen the problems such as.Tradition
Well lid due to lid and base or is split-type structural, or external for hinged place, and such hinged place reforms into a weak spot, holds very much
Easily occur to start with from hinged place to be stolen.
Content of the invention
It is an object of the invention in place of overcoming the deficiencies in the prior art, and a kind of one kind preventing well lid stolen is provided
Anti-stealing manhole cover.
A kind of anti-stealing manhole cover, includes lid and base, and described lid is hinged with base side, lid with
Hinged between base is that the bottom surface of lid is provided with the connecting shaft paralleled with lid, in the setting of the corresponding position of base
There are two open slots arranged side by side that can snap in lid connecting shaft, the trend of described open slot is along horizontal direction, the opening of open slot
Mouth, towards the inside of base, is provided with the communication upper and lower two for pinning open slot opening on two trough rims up and down of open slot
The alignment pin of trough rim.
Using the articulated manner of this lid and base, when using, only need to take away the alignment pin locking in trough rim, you can
Realize removing and installing between lid and base, due to being built-in hinged, therefore can play preferable anti-theft function, with
When also can avoid uncapping, the situation due to the hinged external lid bringing and hinge axis scratch ground occurs.
Whole being embedded in the middle of base when covering of described lid, is locked using buckle between lid and base
Close, several buckle fasteners are arranged on the inwall of base, is provided with and bottom in the corresponding position of the medial surface of lid
The buckle movable part that draw-in groove on seat inwall is used in combination.
Lid, due to being embedded in when lid is sealed in base, is connected with base by the well lid of this structure by buckle,
Lid can be made to be in integrative-structure with base, lid thus can be avoided to beat, thus producing abnormal sound.
Described buckle movable part is the resilient locking arm with lid in integrative-structure, and described buckle fastener is in base
The boss of upper setting.
Irregularly-shaped hole for opening lid is provided with lid.
Irregularly-shaped hole is arranged on lid, needs to be opened using with the ripping bar that irregularly-shaped hole matches on opening, thus can
This is farthest avoided to enter the stolen of lid.
Dovetail groove is provided with the medial wall of base, rubber blanket is set in dovetail groove, described lid is when covering
Contact with rubber blanket.
Base arranges dovetail groove, and rubber blanket is set in dovetail groove so that lid is contacted with rubber blanket, so
The noise that can effectively prevent lid from clashing into base and produce.
The hinged side of base and lid be provided with one along bottom Cuo inside extend a small boss, in the corresponding positions of lid
The place of putting is provided with a vertical movable latch, and vertical movable latch can swing with respect to the junction of lid, and can be little convex in base
Slide on table top, the height of vertical movable latch is equal to or less than vertical movable latch vertical type capping at base small boss
Air line distance, to ensure that lid and base cannot close when vertical movable latch is in obliquity, when vertical movable latch
It is in lid and base during upright locations and can be at closure state.
This structure is set between the base and lid of well lid, when needing to close lid, sets vertical movable latch,
Pass upper cover that thus can be smooth, when in the course of the work, because vertical movable latch is in heeling condition, so once
When lid surprisingly falls, because vertical movable latch is in the state of inclination, therefore can play and prevent lid and base closure
Effect, thus improve the safety of operating personnel.
In sum, the present invention following advantage compared to existing technology：
The anti-stealing manhole cover of the present invention, because lid is built-in with the hinged place of base, on the one hand can play good antitheft work
With the situation that the scratch ground brought is exposed in hinged place on the other hand can be overcome to occur.And due to lid is embedded into base, because
This can be avoided lid to beat, thus producing abnormal sound.Irregularly-shaped hole is set on lid so that wanting the opening lid period of the day from 11 p.m. to 1 a.m to need simultaneously
Specific purpose tool, therefore can play anti-theft function, and setting on base is built-in with the dovetail groove of rubber blanket, therefore also can reduce noise
Generation.The present invention additionally uses this anti-lid accident closing device, has safe and reliable, improves the safety of operating personnel
Property.
