Detailed description of the invention
As employed some vocabulary in the middle of description and claim to censure specific components.Those skilled in the art are it is to be appreciated that hardware manufacturer may call same assembly with different nouns.In the way of this specification and claims not difference by title is used as distinguishing assembly, but it is used as the criterion distinguished with assembly difference functionally." including " as mentioned by the middle of description and claim in the whole text is an open language, therefore should be construed to " including but not limited to ".Description subsequent descriptions is for implementing better embodiment of the present utility model, and right described description is for the purpose of rule of the present utility model to be described, is not limited to scope of the present utility model.Protection domain of the present utility model is when being as the criterion depending on the defined person of claims.
In description of the present utility model, it is understood that, on term " ", D score, " front ", " back side " etc. instruction orientation or position relationship, it is for only for ease of description this utility model and simplifies description rather than instruction or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
Below in conjunction with accompanying drawing, this utility model is described in further detail, but not as to restriction of the present utility model.
A kind of corrosion-resistant telecommunication inspection manhole of environment protection type high-strength, including base 1 and well lid 2, described base 1 is annular frame, a circle annular flange flange 101 it is provided with on described base 1, described base 1 inwall upper end it is connected to bottom described well lid 2, described well lid 2 is embedded in described annular flange flange 101, and described well lid 2 upper surface maintains an equal level with described annular flange flange 101, and described well lid 2 is hinged with described annular flange flange 101.
Particularly preferred, described well lid 2 is provided with lock 3 with the relative other end of described flange 101 hinged place, described lock 3 is fixedly installed on described base 1 inwall upper end, described well lid 2 adjacent edges is provided with open hole 201, described open hole 201 is positioned at directly over described lock 3, be easy to the key locking 3 from described open hole 201 stretch into below well lid 2 open lock 3 thus open well lid 2, can only be opened by key, prevent valuable electric elements stolen.
