Description
Technical field
The utility model relates to inspection well cover technical field, especially relates to a kind of inspection well cover sealing locking structure.
Background technology
In the last few years, with the development that goes from strength to strength of communication industry, the laying project of a large amount of communication cables was created.Communication cable in urban district is laid in the inspection shaft of underground usually.Inspection shaft be above equipped with inspection well cover, the usual shape of inspection well cover be circular in the majority, in order to increase the service life, most ofly to make for cast iron.These iron-cast well lids are present in the streets and lanes in urban district in a large number, when automobile rolls out-of-date, easily cause inspection well cover play and unexpected unlatching phenomenon occurs, bringing potential safety hazard.Therefore, inspection well cover usually adds pattern manhole cover lock.But the pattern manhole cover lock complex structure component of prior art is many, and stand the immersion of rainwater outside due to well lid long term exposure, easily occur the dead phenomenon of rust, substantially increase maintenance management cost and maintenance activity difficulty.
Utility model content
The utility model is for the deficiencies in the prior art, and technical problem to be solved is to provide a kind of inspection well cover sealing locking structure, and its component is few, good reliability, has rainwater leakage prevention function, not easily occurs the dead phenomenon of rust, can use not fragile by long period.
The utility model makes above-mentioned technical problem be solved by the following technical programs.
Inspection well cover sealing locking structure, walling crib and concrete setting integral, inspection well cover and walling crib are entrenched togather, the medial extremity of inspection well cover is hinged with latch hook, latch hook arranges the grab tilted obliquely on a side of walling crib, extended obliquely on the inwall of walling crib have the projection with grab phase counter stopper, another side of latch hook walling crib dorsad arranges balancing weight, the upper end of latch hook is provided with plug, inspection well cover offers the lockhole matched with plug, plug is arranged with and keeps sealing the waterproof apron of fitting with lockhole.In sealing locking mechanism, under the Action of Gravity Field of balancing weight, be hinged on together with latch hook on inspection well cover and the projection in walling crib remain and be firmly hooked on, thus realize inspection well cover and be firmly connected with walling crib and not easily get loose.Plug is arranged waterproof apron and lockhole to seal and fit, effectively prevent rain leakage, thus eliminate the dead phenomenon of rust.Simple and practical, can use and need not keep in repair by long period, reduce maintenance management cost.
As preferably, latch hook is casting component.
As preferably, the protruding structure that is one of the forming with walling crib.
As preferably, the aperture, two ends of lockhole arranges and extends out formula bevel angle.
The beneficial effects of the utility model:
1. component is few, simple and compact for structure, and cost of manufacture is cheap, and operation is convenient, locking bolt pushing plug only need be utilized can to realize latch hook be separated with projection, unclamp locking bolt then self-resetting hook, good reliability, not fragile, long period uses Maintenance free management, greatly reduces maintenance cost.
2. waterproof apron is set and effectively prevents rain leakage, thus ensure that inspection well cover inside is not by rainwater corrosion, avoids the generation of dead phenomenon of becoming rusty.
Accompanying drawing explanation
Fig. 1 is the structural representation under duty of the present utility model.
In figure: 1-walling crib, 2-concrete, 3-inspection well cover, 4-latch hook, 5-grab, 6-is protruding, 7-balancing weight, 8-plug, 9-lockhole, 10-waterproof apron.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in detail below by embodiment.
The utility model inspection well cover sealing locking structure as shown in Figure 1, walling crib 1 and concrete 2 are solidified into one, and inspection well cover 3 and walling crib 1 are entrenched togather.The medial extremity of inspection well cover 3 is hinged with latch hook 4, latch hook 4 may be selected to be casting component, latch hook 4 arranges the grab 5 tilted obliquely on a side of walling crib 1, extended obliquely on the inwall of walling crib 1 have the projection 6 with grab 5 phase counter stopper, protruding 6 can be adopted to be one of the forming structure with walling crib 1, processing technology is simple, has good structural strength.Another side of latch hook 4 walling crib 1 dorsad arranges balancing weight 7, and the upper end of latch hook 4 is provided with plug 8, inspection well cover 3 offers the lockhole 9 matched with plug 8, plug 8 is arranged with and keeps sealing the waterproof apron 10 of fitting with lockhole 9.Conveniently use locking bolt pushing plug 8 can not cause stuck phenomenon in lockhole 9, the aperture, two ends of lockhole 9 can be selected to arrange extend out formula bevel angle.
The utility model is not limited to above-mentioned embodiment; the architectural feature of latch hook and also can adopt the malformation of other equivalent transformations in the middle of known technology with the articulated manner of inspection well cover; as long as belong to technical conceive of the present utility model or spirit; by being hinged on latch hook on inspection well cover together with being arranged on the projection in walling crib and being hooked on mutually; firmly be connected with walling crib to realize inspection well cover; meanwhile, realize avoiding the embodiment for the purpose of rain leakage all to drop in protection domain of the present utility model by arranging waterproof apron.
