Description
Technical field
The utility model relates to inspection well cover technical field, especially relates to Inspection shaft cover lock opening and closing 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iron-cast well lids are present in the streets and lanes in urban district in a large number, when automobile rolls out-of-date, easily cause inspection well cover play and unexpected unlatching phenomenon occurs, bringing potential safety hazard.Therefore, inspection well cover usually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.For this reason, usually change the structure of original inspection well cover, and reduce structural strength.Further, the pattern manhole cover lock long term exposure of prior art stands the immersion of rainwater outside, easily occurs corrosion and is difficult to opening and closing, for the work of maintenance personal brings difficulty.
Utility model content
The utility model is for the deficiencies in the prior art, technical problem to be solved is to provide a kind of Inspection shaft cover lock opening and closing structure, and it does not reduce on the basis of the structural strength of existing inspection well cover, realizes the locking function between inspection well cover and walling crib, and opening and closing is convenient and swift, not easily there is the dead phenomenon of rust.
The utility model makes above-mentioned technical problem be solved by the following technical programs.
Inspection shaft cover lock opening and closing structure, walling crib and concrete setting integral, inspection well cover and walling crib are entrenched togather, the medial extremity of inspection well cover is articulated with latch hook, latch hook is provided with grab on the outboard end of walling crib, extended on the inwall of walling crib have the stopper protrusion coordinated with grab, inspection well cover offers the lock bolt jack that locking bolt is passed, and the medial extremity of latch hook walling crib is dorsad provided with and touches for locking bolt the spacing thrust structure realizing locking or unlocking motion between grab and stopper protrusion.On the basis of original inspection well cover and walling crib, set up latch hook and the stopper protrusion of Split type movable kayser function, at all do not affect overall construction intensity, locking or unlocking motion can be realized easily by the locking bolt spacing thrust position promoted on latch hook, operate extremely convenient and swift, and split type syndeton itself have not easy rusting dead advantage.
As preferably, the U-shaped structure of latch hook, the vertical section of two side is fan-shaped, and the upper end of two side is symmetrically arranged with pivot toward the outer side, and diapire is upwards extended between two side thrust sidewall.As improvement, thrust sidewall is extended with anticreep projection towards interior lateral bend.Further improvement, extended on diapire have grab.
As preferably, latch hook is integrated casting structure.
As preferably, locking bolt is set to dome shape contact connector for the one end touching latch hook.As improvement, lock bolt jack is bar hole towards one end of walling crib, bar hole dorsad walling crib one end be communicated be provided with the circular hole matched with contact connector, the diameter of circular hole is greater than the width of bar hole.
The beneficial effects of the utility model:
1. separation type lock locking structure is simple and practical, easy to operate, good reliability, not easily occurs the dead phenomenon of rust.
2. do not reduce structural strength, locking mechanism is durable, not fragile, the unexpected potential safety hazard that the external force such as effectively prevent that wheel from rolling causes inspection well cover play to cause.
Accompanying drawing explanation
Fig. 1 is the structural representation under duty of the present utility model;
Fig. 2 is the perspective view of latch hook of the present utility model;
Fig. 3 is the structural representation of lock bolt jack of the present utility model.
In figure: 1-walling crib, 11-stopper protrusion, 2-concrete, 3-inspection well cover, 4-latch hook, 41-grab, 42-pivot, 43-thrust sidewall, 44-anticreep is protruding, 5-locking bolt, 6-lock bolt jack, 61-bar hole, 62-circular hole.
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 shaft cover lock opening and closing structure as shown in Figure 1 to Figure 3, walling crib 1 and concrete 2 are solidified into one, inspection well cover 3 and walling crib 1 are entrenched togather, the medial extremity of inspection well cover 3 is articulated with latch hook 4, latch hook 4 is provided with grab 41 on the outboard end of walling crib 1, extended on the inwall of walling crib 1 have the stopper protrusion 11 coordinated with grab 41, inspection well cover 3 offers the lock bolt jack 6 that locking bolt 5 is passed, the medial extremity of latch hook 4 walling crib 1 is dorsad provided with to touch for locking bolt 5 and realizes locking between grab 41 and stopper protrusion 11 or the spacing thrust structure of unlocking motion.As a kind of embodiment of latch hook 4, as shown in Figure 2, latch hook 4 is integrated the U-shaped structure of casting, and the vertical section of two side is fan-shaped, and the upper end of two side is symmetrically arranged with pivot 42 toward the outer side, and diapire is upwards extended between two side thrust sidewall 43.In order to better coordinate locking bolt 5 touch force on thrust sidewall 43 and prevent depart from, be extended with anticreep projection 44 at thrust sidewall 43 towards interior lateral bend, grab 41 is extended from diapire.As a kind of embodiment of locking bolt 5, locking bolt 5 is set to dome shape contact connector for the one end touching latch hook 4, it is bar hole 61 that the lock bolt jack 6 coordinated with locking bolt 5 is set to towards one end of walling crib 1, bar hole 61 dorsad walling crib 1 one end be communicated be provided with the circular hole 62 matched with contact connector, the diameter of circular hole 62 is greater than the width of bar hole 61.
The utility model is not limited to above-described embodiment; the known technology that the contour structures of latch hook, stopper protrusion and connected mode also can adopt those skilled in the art to obtain or other the embodiment that the central equivalence of prior art is replaced; as long as belong to technical conceive of the present utility model or spirit; stopper protrusion being set in walling crib by arranging latch hook on inspection well cover simultaneously, being connected by the split type kayser of latch hook and stopper protrusion and all dropping in protection domain of the present utility model by the embodiment realized for the purpose of inspection well cover rust protection locking function.
