Description

Magnetic lock

Technical field

The utility model relates to a kind of structure of lock, and what be specifically related to is a kind of structure of magnetic lock.

Background technology

At present, such as anti-theft lock for motored vehicle, gate lock, the tapered end on it all is the tapered end that adopts cylinder type, and the tapered end of this structure is applied on the motor vehicle lockset, and perhaps on some padlocks, its theftproof performance is relatively poor.Look into Chinese patent database, an a kind of denomination of invention is " a card form magnetic lock ", notice of authorization number is the utility model patent of CN2358165Y, following content is disclosed: a kind of card form magnetic lock, comprise the lock body that has lock core, the key of Pei Heing reaches the opening mechanism that is connected with lock core with it, it is characterized in that: the keyhole on the lock body is a card hole, at least one side is distributed with the magnetic marble that is installed in the pellet shot from a slingshot hole in the hole, and with inner corresponding position, pellet shot from a slingshot hole have have with lock body in the distribute lock core of identical blind hole of pellet shot from a slingshot, lock core is logical to be connected with opening mechanism with lock body is outer, with card-shape that keyhole adapts have on the key with lock body in the magnetic marble distribution identical, the magnetic patch that magnetic pole is relative.The lock of this structure is not still jumped out the circle circle of lockmaking traditionally, still will adopt the structure of lock core, because its processing technology complexity of structure of lock core, and the cost of product is improved greatly, so be not suitable for such as on the padlock class.The lock of this structure of while, it also is not very convenient using.

The utility model content

In view of the deficiency that background technology exists, the technical problems to be solved in the utility model provides the magnetic lock that a kind of theftproof performance is strong, mutual opening rate is low.

For this reason, the utility model is realized by the following technical solutions: a kind of magnetic lock, has lock, on the described lock dead bolt hole is set, pellet shot from a slingshot hole seat and locking bar jack, in the described dead bolt hole dead bolt is installed, and the dead bolt dead bolt hole communicates with described jack, one end of described dead bolt contacts with first spring, it is characterized in that in the seat of described pellet shot from a slingshot hole magnetic bullet being installed, above the seat of pellet shot from a slingshot hole, copper coin is set, and the copper coin top is separately installed with iron plate, following corrosion resistant plate, described copper coin is provided with and the corresponding circular hole in described pellet shot from a slingshot hole, described iron plate and notch of following corrosion resistant plate formation gone up for the key insertion, described key is an inserted sheet, which is provided with the repulsion position corresponding with described pellet shot from a slingshot, first inclined-plane is set on the described dead bolt, described copper coin is provided with second inclined-plane with first inclined-plane of described dead bolt coupling, described copper coin is provided with block face near a side of described dead bolt, the both sides of described pellet shot from a slingshot hole seat are provided with groove, second spring is installed in the described groove, be respectively equipped with the support corresponding with described groove on described copper coin, described support can slide in described groove, and an end of described second spring contacts with described support; Described top of going up iron plate is equipped with the 3rd spring, and described the 3rd spring top has gland, and described gland is fixedlyed connected with described lock; In described pellet shot from a slingshot hole, be provided with micropore, the exterior of this micropore and described lock.

The magnetic lock of this structure, can be according to the variation that the pellet shot from a slingshot position is installed on the pellet shot from a slingshot seat, increase its coding, thereby reduced mutual opening rate, improved theftproof performance, and adopted the key of blade inserting, the feasible more laborsaving convenience of unblanking, and behind the micropore and lock exterior that are provided with in the pellet shot from a slingshot hole, the rainwater that enters in the pellet shot from a slingshot hole is flow to the lock outside by micropore, make this lockset have the function of waterproof.
