Abstract
The invention discloses a grounding wire clamp lock structure which is simple in structure and convenient to use and capable of effectively avoiding safety accidents due to man-made conscious or unconscious violation operations on a grounding wire clamp. The grounding wire clamp lock structure comprises a lock body, a sleeve (2) capable of idling in the lock body and a pull rod (3) slidably matched with the lock body. The lock body comprises a spring bolt (4) arranged in the lock body, a yield groove (5) corresponding to the spring bolt (4) in position is arranged on the pull rod (3), a hole (6) used for inserting of the pull rod (3) is formed in the sleeve (2), and the sleeve (2) is fixedly connected with the tail end of a locking rod of the grounding wire clamp. The grounding wire clamp lock structure can be applied to the electric power security system.
Description
Technical field
The present invention relates to a kind of safety lock structure, particularly relate to a kind of earthing clamp lock construction that can be applicable to electric power safety system regions.
Background technology
In the maintenance of power system device and circuit, short-circuit grounding wire is very important technical measures for electric safety; Use the object of short-circuit grounding wire to be to leak residual charge, the dangerous voltage produced that prevents from sending a telegram here suddenly causes personal injury to electric operating personnel.Usually, all earthing clamp can be connected with at the end of the short-circuit grounding wire collected; Earthing clamp more common is at present exactly C type plain end screw earthing clamp, and not only structure is simple, easy to use for this kind of earthing clamp, and reliability is higher; But; people but have ignored the protection of earth wire folder when constantly improving earthing clamp; earthing clamp is brought significant threat can to equally the personal safety of electric operating personnel by the intentional or unintentional violation operation of people; as can be seen here, the protection of earth wire folder should cause the great attention of power domain worker.
The protection of prior art earth wire folder is only set up a locking bin in earthing clamp outside; though the violation operation that this kind of mode can prevent people's earth wire from pressing from both sides; if but when needing earth wire folder to carry out manual operation according to actual conditions; its operating process is comparatively loaded down with trivial details, and the locking bin set up also can take a part of space resources.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provides simple, the small and exquisite facility of a kind of structure and can effectively avoid being had a mind to by people due to earthing clamp or being not intended to violation operation and causing the earthing clamp lock construction of security incident.
The technical solution adopted in the present invention is: the present invention includes lock body, the sleeve dallied in described lock body inside and the pull bar be slidably matched with described lock body, described lock body comprises the dead bolt be provided at its inner portion, 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 is in locking states, described sleeve is in idling conditions, now earth wire folder locking rod cannot realize rotary manipulation; When described lock body is in released state, described pull bar can freely-movable, described pull bar is inserted described duct and makes described sleeve be in idling state, now earth wire folder locking rod can realize rotary manipulation.
Described lock body also comprises shell and is successively set on the chip of described enclosure, lock core and elastic component 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 is through the cavity on described dead bolt.
Described pull bar is also symmetrically arranged with two keyways, two described keyways are suitable with the symmetrical pin be fixedly installed on described lock body.
Described sleeve top is provided with translot and is also 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, the sleeve dallied in described lock body inside and the pull bar be slidably matched with described lock body, described lock body comprises the dead bolt be provided at its inner portion, 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 described lock body, so degree of tightness adjustment cannot be carried out by described lock body earth wire folder locking rod, and then ensure that earthing clamp not by intentional or unintentional violation operation; If when needing earth wire folder to carry out degree of tightness adjustment according to actual conditions, first with key, described lock body should be unlocked, described pull bar after unblock can freely be pulled out, then described pull bar being inserted described duct makes described sleeve be in idling state, be in the spanner that the described sleeve of idling state and described pull bar constitute earthing clamp locking rod, and then the ground clamp locking rod degree of tightness that can achieve a butt joint regulates.
In sum, the present invention is simple, the small and exquisite facility of a kind of structure and can effectively avoids being had a mind to by people due to earthing clamp or being not intended to violation operation and causing the earthing clamp lock construction of security incident.
Further, described lock body in the present invention also comprises shell and is successively set on the chip of described enclosure, lock core and elastic component 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 is through the cavity on described dead bolt; Be not difficult to find out by said structure, the described lock body in the present invention is magnetic code lock, and this kind of magnetic code lock further increases safety of the present invention.
Further, owing to described pull bar being also symmetrically arranged with two keyways, two described keyways are suitable with the symmetrical pin be fixedly installed on described lock body, thus the present invention use fast, operate simple and easy.
