Abstract
The utility model relates to a fully closed permanent magnetic lock for a manhole cover, which is composed of a magnetic ball key, a lock body shell, a lock body and a lock core, wherein, a magnetic pole is arranged on the magnetic ball key and is opposing to the magnetic pole in the lock core. When the magnetic ball key enters a lock hole through a guide groove, the magnetic pole of the lock core is pushed off by the magnetic pole on the magnetic ball key, and thus the lock core and the lock body are separated and rotated to drive a connecting plate to open the manhole cover. The utility model has the advantages of high safety, theft protection, water resistance, corrosion-proofing, simple structure and convenient installation, and is suitable for drainage, telecom, underground installations of electricity industries and manhole covers of road surfaces of towns.
Description
The utility model relates to a kind of lockset.
At present; using casting iron well lid on numerous urban street; these well lids are not locked often, therefore usually can lose, and bring dangerous to traffic; annual each city all has an accident because of well lid is stolen; casualties accident happens occasionally, and relevant department once used anti-stealing manhole cover, but this well lid is bulky; complex structure, loading and unloading are extremely inconvenient.In addition, lock body needs waterproof and dustproof, antirust, corrosion-resistant, makes traditional lockset can't reach above-mentioned requirements, thereby this class anti-stealing manhole cover is difficult to promote the use of.
The purpose of this utility model is to overcome the deficiency that above-mentioned known technology exists, thereby provides a kind of full-enclosed permanent-magnet ground well lid special-purpose lock, both can be antitheft, and waterproof again, antirust, dustproof, anticorrosion, simple in structure, easy for installation.
The purpose of this utility model realizes in the following way:
This special use lock comprises magnetic marble key (1), lock body shell (2), lock body (3) and lock core (4), wherein, have magnetic post (10) on the magnetic marble key (1), corresponding magnetic post (10) radially has the hole at lock body (3) and lock core (4) along key, have the relative magnetic post (8) of a pair of homopolarity in the hole, magnetic post (10) is relative with adjacent magnetic post (8) homopolarity, have sealing ring (7) along the keyhole cylindrical between lock body shell (2) and the lock core (4), seal rubber sleeve (5) is in the end sealing of the other end with lock body shell (2) and lock body (3).
Lock core (4) tail end is threaded, and passes seal rubber sleeve (5), and links to each other with junction plate (9) by clamp nut (6).
Have gathering sill on the keyhole, corresponding with guide pillar on the key, be convenient to key and correctly insert unlatching.
The utility model compared with prior art has following advantage:
(1) this special use lock has adopted permanent-magnet material, and pellet shot from a slingshot is not exposed, and can not be subjected to the influence of extraneous water, dirt, reduces the lock body size, simplifies the structure.
(2) this lock adopts totally-enclosed design, and the rear defence water logging is installed, and dirt resistance and corrosion are specially adapted to open-air open-air permanent the use.
(3) this special use lock is gone back preventing key individual preparation, preventing universal key, size of key height, has higher safety, and key unlocking has versatility, and the staff can be led to the pattern manhole cover lock of turning up the soil after grasping in own working range.
(4) simple in structure, volume is little, well lid is easy for installation, especially is fit to the transformation of old well lid.
The utility model is described in further detail below in conjunction with accompanying drawing
Fig. 1 is the utility model front view
In Fig. 1: (1) magnetic marble key; (2) lock body shell; (3) lock body; (4) lock core; (5) seal rubber sleeve; (6) clamp nut; (7) sealing ring; (8) magnetic post; (9) junction plate; (10) magnetic post.
As shown in the figure, key body is cylindrical, insert in the lockhole, and gathering sill is relative with on the key guide pillar, this moment, interior magnetic post (8) homopolarity of one circle magnetic post (10) (can be 12) and lock core of key body was relative, mutually exclusive, make magnetic post (8) radially groove move outward, lock core (4) and lock body (3) break away from like this, key can drive lock core (4) and rotate, drive junction plate (9) and open the locking bolt of well lid, realize opening.Extract key, every pair on magnetic post (8) repels mutually, enters lock core, and is fixed.Sealing ring (7) and seal rubber sleeve (5) can adopt oil resistant glue, and lockhole is open-minded at ordinary times, sluice as well lid and use.
Except that doing the use of draining well lid, the utility model also can be used as all kinds of underground installation road surface manholes such as telecommunications, electric industry and uses.
