Abstract
The invention discloses an outdoor high-voltage switch cabinet lock, which comprises a lock casing and a lock core. The lock core is arranged in the lock casing; the front end of the lock core is connected with a rear end of an extension rod; a front end of the extension rod extends out of the lock casing and is vertically connected with a lock tongue; two symmetric guide bosses which extend from the inner wall of the lock casing to the lock core are arranged between the inner wall of the lock casing and the lock core; the guide bosses are provided with oil filling through holes; and felt is filled in the oil filling through holes. The lock is simple in structure and convenient to operate, and can continuously keep lubrication of the lock core.
Description
Technical field
The present invention relates to a kind of lockset, particularly be installed in outdoor high-tension switch cabinet lock.
Background technology
At present, the structure of outdoor high-voltage switch cabinet lock commonly used comprises lock housing, lock core and dead bolt composition, and lock core rotates in lock housing, thereby drives the dead bolt action that is fixedly connected on the lock core.This structure be locked in concrete use the time, the weak point of existence is; Owing to outdoor inclement condition, often to be subjected to the erosion of rainwater, after long-term the use, seal seals variation owing to wear out, and like this, rainwater is easy to enter lock core by lock housing, causes the corrosion of lock core; Lock core often rotates the phenomenon of clamping stagnation, influences its normal use.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of outdoor high-voltage switch cabinet lock that can make lock core keep normal rotation for a long time is provided.
The technical solution used in the present invention is: comprise lock housing and lock core, lock core is arranged in the lock housing, the lock core front end is connected with the extension rod rear end, the extension rod front end stretches out outside the lock housing and vertically connects a dead bolt, between the inwall of lock housing and lock core, be provided with 2 symmetries and the guide ledges of extending to lock core by the inwall of lock housing, in guide ledges, be provided with and add oil hole, add and be placed with malthoid in the oil hole.
Further, the angle of guide ledges of the present invention and lock core central axis is 45 degree.
The present invention is simple in structure, and is easy to operate, and sustainable maintenance lock core is lubricated.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a structure chart of the present invention;
Among the figure: 1. lock housing; 2. lock core; 3. dead bolt; 4. primary nut; 5. extension rod; 6. add oil hole; 7, guide ledges; 8. malthoid.
The specific embodiment
Referring to Fig. 1, the present invention includes lock housing 1 and lock core 2, lock core 2 is a cylindrical structure, lock core 2 is arranged in the lock housing 1, the rear end of the fixedly connected extension rod 5 of the front end of lock core 2, the front end of extension rod 5 stretches out outside the lock housing 1, and is processed with screw thread on the front end of extension rod 5, by dead bolt 3 of the vertical installation of this screw thread, dead bolt 3 is fixing by primary nut 4.
The guide ledges 7 of 2 symmetries is set between the inwall of lock housing 1 and lock core 2, and this guide ledges 7 is extended to lock core 2 by the inwall of lock housing 1, and the angle of guide ledges 7 and lock core 2 central axiss is 45 degree.In guide ledges 7, have and add oil hole 6, add oil hole 6 connection the outer wall and the outside of lock core 2, in adding oil hole 6, place malthoid 8, the external diameter of malthoid 8 with add oil hole 6 internal diameters and closely cooperate.
The present invention in use, lubrication oil injects by adding oil hole 6, after absorbing by malthoid 8; enter into the outside wall surface of lock core 2; surface at lock core 2 forms oil film, and when the corresponding lock core hole of key insertion lock core 2 rear ends drove lock core 2 rotations, lock core 2 can be protected lubricating status all the time.If transform to being installed in outdoor original lockset, only need add oil hole, and place malthoid and get final product in original lock housing, can not change structure and permanent position that original outdoor high-voltage switch cabinet is locked, also need not to dismantle original lockset.
