Description

The masking device that lockset is used

Technical field

The utility model relates to the masking device that a kind of lockset is used, and refers to a kind of being arranged on the locomotive lock especially, is used for covering the keyhole of this lockset, and needs to unlock to open keyhole second burglary-resisting installation by magnetic key.

Background technology

On at present commercially available locomotive, turn to tap and cut off the locomotive power-supply system except adopting conventional lock to be used for locking, a kind of another second burglary-resisting installation still is provided, make that the anti-theft measure of locomotive is more perfect, this second burglary-resisting installation normally is installed at the keyhole place of lockset, be used for covering this keyhole, prevent to separate the locking of unlocking tool for locomotive in wrongful mode.

This second burglary-resisting installation is to adopt the release mode different with commercially available lockset, strengthen its antitheft effect, as a rule this second burglary-resisting installation is the design of adopting magnetite induction release, as TaiWan, China announce No. 592186 " the locomotive locking closure of attached means for screening " its mainly be the keyhole place that the locking closure that will be pivoted with shield is arranged at locomotive lock, utilize the rotation of shield to hide keyhole, make before not untiing the shield of locking closure, can't penetrate operation lockset release in the keyhole with key or other instrument, and this locking closure further provides a magnetic lock, the pin that utilization has magnetic locks the switch block on the magnetic lock, when the magnetic key with correspondence penetrates switch block, the characteristic of utilizing same polarity to repel each other, make the interior pin of magnetic lock untie locking to switch block, further rotatable switch block drives a holding firmware, make the engaging of this holding firmware disengaging to shield, then this shield reveals the keyhole of lockset with regard to rotating removing, and so just can utilize corresponding key to separate the locking of unlocking tool for locomotive.

Described this known locking closure is the design of adopting the magnetic release, utilizes the release mode of core mechanical action that great difference is arranged with the known lockset that is used on the locomotive, makes that thus the anti-theft measure of locomotive is more perfect.

But, described locking closure is in the design of release action, be to be passed to holding firmware by rotatablely moving of switch block to become straight reciprocating motion, therefore in the transmission of strength, have the problem of dispersion, that is to say, strength direction when switch block rotates and holding firmware travel direction are also non-parallel, cause strength to disperse and to transmit completely, moreover, the portion of pressing that this switch block has is connected to a side of holding firmware, when strength transmission during to holding firmware, can make holding firmware produce turning moment, make holding firmware toward a sidewall against, when therefore holding firmware is made reciprocal rectilinear motion, can produce bigger frictional force, make the user when operation, need rotate this switch block and order about the shield rotation, have some setbacks in the operation with bigger strength.

Again, described locking closure practical set is on locomotive the time, and this switch block is the place, top that keeps right that is positioned at locking closure, because herein near the housing of locomotive body, therefore the space of operation is narrower and small, this also is to be worth improvements.

The utility model content
