Description
Technical field
The present invention relates to a kind of safety lock structure, relate in particular to a kind of earthing clamp lock construction that can be applicable to electric power safety system field.
Background technology
In the maintenance of power system device and circuit, short-circuit grounding wire is very important technical measures for electric safety; The purpose of using short-circuit grounding wire is in order to leak residual charge, to prevent that the dangerous voltage that unexpected incoming call produces from causing personal injury to the electric operating personnel.Usually, the end at the short-circuit grounding wire that compiles all can be connected with earthing clamp; More common earthing clamp is exactly C type plain end screw earthing clamp at present, and this kind earthing clamp is not only simple in structure, easy to use, and reliability is higher; Yet; people have but ignored the protection of earth wire folder when constantly improving earthing clamp; earthing clamp had a mind to by the people or unintentionally violation operation can bring significant threat to electric operating personnel's personal safety equally; this shows, the protection of earth wire folder should cause power domain worker's great attention.
The protection of prior art earth wire folder only is to set up a bin with lock in the earthing clamp outside; though this kind mode can prevent the violation operation of people's earth wire folder; if but when carrying out manual operation according to actual conditions needs earth wire folder; its operating process is comparatively loaded down with trivial details, and the bin with lock of setting up also can take a part of space resources.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, a kind of facility simple in structure, small and exquisite is provided and can effectively avoids because the earthing clamp lock construction that earthing clamp is had a mind to by the people or violation operation causes security incident unintentionally.
The technical solution adopted in the present invention is: the present invention includes lock body, reach the pull bar that is slidingly matched with described lock body at the inner sleeve that dallies of described lock body, described lock body comprises the dead bolt of the section of setting within it, described pull bar is provided with the position slot to make way corresponding with described dead bolt, described sleeve is provided with the duct of inserting for pull bar, and described sleeve is fixedly connected with the tail end of earthing clamp locking rod; When described lock body was in locking states, described sleeve was in idling conditions, and can't earth wire folder locking rod realize rotary manipulation this moment; When described lock body is in released state, but described pull bar freely-movable described pull bar is inserted described duct makes described sleeve be in the non-idling state, but this moment, earth wire folder locking rod realized rotary manipulation.
Described lock body also comprises shell, reaches the chip, lock core and the elastic component that are successively set on described enclosure from top to bottom, described elastic component one end contacts with described outer casing inner wall, its other end contacts with described dead bolt, the lower end of described lock core is provided with lug boss, and described lug boss passes the cavity on the described dead bolt.
Also be symmetrically arranged with two keyways on the described pull bar, two described keyways are suitable with the symmetrical pin that is fixedly installed on the described lock body.
Described sleeve top is provided with translot and also is provided with screwed hole on the periphery of described sleeve.
Described shell comprises upper cover plate, mesochite and lower cover.
The invention has the beneficial effects as follows: the present invention includes lock body, reach the pull bar that is slidingly matched with described lock body at the inner sleeve that dallies of described lock body, described lock body comprises the dead bolt of the section of setting within it, described pull bar is provided with the slot to make way corresponding with described latch bolt position, described sleeve is provided with the duct of inserting for pull bar, and described sleeve is fixedly connected with the tail end of earthing clamp locking rod; When described lock body is in locking states, owing to being in idling conditions between described sleeve and the described lock body, regulating so can't carry out degree of tightness by described lock body earth wire folder locking rod, and then guaranteed that earthing clamp is not had a mind to or unintentionally violation operation; If when carrying out the degree of tightness adjusting according to actual conditions needs earth wire folder, should be first with key with described lock body release, described pull bar after the release can freely be pulled out, then described pull bar being inserted described duct makes described sleeve be in the non-idling state, the described sleeve and the described pull bar that are in the non-idling state have formed the spanner of earthing clamp locking rod, and then the ground clamp locking rod degree of tightness that can achieve a butt joint is regulated.
In sum, the present invention is that a kind of facility simple in structure, small and exquisite also can effectively be avoided the earthing clamp lock construction owing to earthing clamp is had a mind to by the people or violation operation causes security incident unintentionally.
Further, described lock body among the present invention also comprises shell, reaches the chip, lock core and the elastic component that are successively set on described enclosure from top to bottom, described elastic component one end contacts with described outer casing inner wall, its other end contacts with described dead bolt, the lower end of described lock core is provided with lug boss, and described lug boss passes the cavity on the described dead bolt; Be not difficult to find out by said structure, the described lock body among the present invention is the magnetic code lock, and this kind magnetic code lock has further improved safety of the present invention.
Further, owing to also being symmetrically arranged with two keyways on the described pull bar, two described keyways are suitable with the symmetrical pin that is fixedly installed on the described lock body, so that the present invention uses fast, operates is simple and easy.
