Description

A kind of novel circumference lamina idle-run padlock

Technical field

The utility model relates to lock technology fields, and in particular to a kind of novel circumference lamina idle-run padlock.

Background technique

Currently, existing lock core is non-idle-run lock pin mostly on the market, after being inserted into correct key, lock core could be unlocked, such as Fruit shaped as key bit is incorrect, cannot open this lock, and strong twist will destroy key and lock core.In addition, when not unlocking, lock core Lock gall be it is fixed, when being destroyed using electric drill, drill bit rotation be easy by lock gall violence damage, the anti-drilling performance of such lock core is just It is poor.The lock core also in that be difficult to of various types lockset keeps out thief and turns round sled using hard special tool strength at present Or violence is opened and is opened, and pilferage case is caused frequently to occur, therefore, people had been continually striving to find the side solved in recent years Method and invented several racing locks, the patent of invention that China Patent No. is 200610037597.2: lamina capable of turning turns 360 ° anti- Steal tapered end, China Patent No. 200810030910.9, the title of innovation and creation are as follows: the tapered end with idle-run lock pin.Above-mentioned two hairs It is bright to realize the Lock cylinder idling when strength turns round picking lock core and lock tongue is not driven to rotate, have effects that prevent from prying open lock by strong torsion. But shortcoming is: 1, structure is complicated, components lead to high failure rate more；2, machine parts'precise, processing difficulties cause at high cost； 3, because of strip, arc slide plate inside and outside the narrow inside of lock core adds or front and back lock core, locking side column are added etc. and many Tiny elastic element, and the different groove of machining shape on tiny pellet or blade, make lock core by hollow out, and rigidity is owed It lacks, slightly dust or dirt, which enter, results in idle running failure or even itself original key is not opened lock yet；4, most important Be: their blade is radial blade, and working principle is: when normally-open, many parts first make radial motion again inside lock core Switching to axial movement, rotary motion goes that lock tongue is driven to open lockset again；Therefore, as long as there is a link failure in all too many levels, Just at problem lockset or does not open and scrap.

Utility model content

Aiming at the shortcomings in the prior art, the utility model provides a kind of novel circumference lamina idle-run padlock, and structure is simple, It is ingenious in design, by the special designing to blade set and circumferential vanes structure, unlock under unmatched key, lock core meeting Idle running, enhances anti-drilling & antidamage function by rotatable 360 °, so that the safety coefficient of lockset is improved, and product easy processing, lock core Rigidity is good, and failure rate is low.

The utility model is achieved through the following technical solutions: a kind of novel circumference lamina idle-run padlock, including lock body, lock Core, lock bridge, key, it is characterised in that: the lock core is fixedly mounted in lock body by threaded capping, and is locked opening Under beam-like state, detachable lock core, the lock core includes blade set, circumferential vanes, partition and needle roller, passes through the circumference of not jack per line Blade and partition are spaced apart with blade set, and it is corresponding with blade matched to play the role of the variation of key tooth flower tooth form；It is described Blade is put on equipped with needle roller card slot and fixed partition card slot, and the needle roller card slot comes for controlling needle roller band movable vane piece set rotation It pushes two steel ball tongues to move in or out in lock bridge groove, plays the role of open or block, the fixed partition card slot is Vertical hollow groove, for blocking the lug boss of partition, control partition rotation, the circumferential vanes circumferential edges are equipped with a cooperation The recess portion of needle roller rotation, and convex portion of the circumferential vanes circumferential edges without any rotation.The circumferential vanes circumferential edges do not have There is the convex portion of any rotation, this is and conventional common blade structure is different is specifically designed.So said structure design Novelty essentially consist in circumferential vanes and blade set improvement, original circumferential vanes be equipped with boss, original blade set Only one needle roller card slot and 105 ° of blade inner wall grooves are designed for blocking circumferential vanes and partition, so circumferential vanes 360 ° of idle running are unable to reach, present blade puts on the fixed partition card slot of setting, and partition is only blocked in the card slot hollow setting vertically, Blocking of the circumferential vanes without lug boss, circumferentially shape, can make circumferential vanes reach idle running, and only key is matched with blade number, side Needle roller down enters the recess portion of lock core sleeve card slot and blade, and under the rotation of key, blade drives needle roller and lock core sleeve rotation, opens and hangs Lock.When other diamond pieces are inserted into, it empty can only bore, can not destroy and open, be unable to reach so overcoming circumferential vanes lock completely The shortcomings that lost motion functionality, and also overcome original racing lock structure is complicated, components lead to high failure rate, lock core rigidity more Difference, processing lead to the disadvantages of at high cost slowly.

Preferably, the threaded capping is helicitic texture, and the threaded side wall of the threaded capping is additionally provided with fixation hole, The lock body side is equipped with a tapped through hole, when threaded capping is tightened on lock body, can pass through screw thread with hexagon socket head cap screw Through-hole is tightened on the fixation hole of capping.Original threaded capping is helicitic texture, is tightened on lock body, in order to Pick-proof performance is promoted, fixation hole is arranged in the threaded side wall of capping in we, and in order to allow fixed screw precession to go, we are in lock body side Tapped through hole is arranged in face, and when screw is placed on threaded hole, screw tightening can be fixed on capping by tapped through hole by screwdriver Side wall fixation hole on, it is dual to tighten, improve the anti-damage ability of capping.

Preferably, the another side of the lock body is equipped with steel ball hole, blocks steel ball for installing steel ball tongue, and with mounting Hole.

Compared with prior art, the utility model has the following beneficial effects: the utility model structure is simple, design is skilful It is wonderful, by blade set and circumferential vanes special construction design, make lock core sleeve blade in the unmatched situation of key Padlock is opened, 360 ° of blade idle running in lock core sleeve, fail to open padlock；If key is matched with blade number, sidewinders needle down and enter Blade covers the recess portion of card slot and blade, and under the rotation of key, blade drives needle roller and blade set rotation, opens padlock.To Improve the safety coefficient of padlock；Enhance anti-drilling anti-violence damage open function；And product easy processing produces, and failure rate is low, opens It opens flexibly, rigidity is good, and securely.
