Shielding device for locks

technical field

The utility model relates to a shielding device for a lock, in particular to a second anti-theft device which can be arranged on a locomotive lock and used to shield a key hole of the lock, and needs to be unlocked by a magnetic key to open the key hole.

Background technique

On the current commercially available locomotives, in addition to adopting traditional locks to lock the steering tap and cut off the locomotive power supply system, another second anti-theft device is provided to make the anti-theft measures of the locomotive more perfect. This second anti-theft device is usually It is installed at the key hole of the lock to cover the key hole and prevent the lock from unlocking the locomotive in an improper way.

This second anti-theft device adopts a different unlocking method from commercially available locksets to enhance its anti-theft effect. Generally speaking, this second anti-theft device adopts the design of magnet induction unlocking, as in the announcement No. 592186 of Taiwan, China. "Locomotive lock cover with shielding mechanism" is mainly to place the lock cover pivoted with the shield plate at the key hole of the motorcycle lock, and use the rotation of the shield plate to cover the key hole, so that before the shield plate of the lock cover is unlocked, It is impossible to use a key or other tool to penetrate into the keyhole to operate the lock to unlock, and the lock cover further provides a magnetic lock, using a magnetic pin to lock a switch block on the magnetic lock, when a corresponding magnetic key is inserted When the switch block is used, the same polarity is used to repel each other, so that the pin in the magnetic lock unlocks the lock on the switch block, and the switch block can be further rotated to drive a clamping piece, so that the clamping piece is out of engagement with the shielding plate. Then the shielding plate can be rotatably removed to expose the key hole of the lock, so that the corresponding key can be used to unlock the lock for the locomotive.

The known lock cover adopts the design of magnetic unlocking, which is very different from the unlocking method of the known lockset used on the locomotive by the mechanical action of the lock core, thus making the anti-theft measures of the locomotive more perfect.

However, in the design of the unlocking action of the lock cover, the rotary motion of the switch block is transmitted to the clamping member to become a linear reciprocating motion, so there is a problem of dispersion in the transmission of power, that is to say, the switch block rotates When the direction of the force is not parallel to the direction of movement of the clip, the force is scattered and cannot be completely transmitted. Furthermore, the contact part of the switch block is in contact with one side of the clip. When the force is transmitted to the clip, it will Make the clip generate a rotational moment, so that the clip leans against the side wall, so when the clip makes a reciprocating linear motion, it will generate a large friction force, so that the user needs to use a large force to turn the switch when operating The block drives the shielding plate to rotate, and the operation is not smooth.

In addition, when the lock cover is actually assembled on the locomotive, the switch block is located at the upper right side of the lock cover. Since it is closer to the housing of the locomotive body, the operating space is relatively narrow, which is also worthy of improvement. .
