Abstract

A cam lock with a lock cylinder capable of running idly relates to the field of cam locks, and is particularly used for preventing unlocking through violently damaging lock cylinders of cam locks. The utility model aims at preventing people from plugging other objects into a key hole to violently unlocking or damaging locks. The cam lock comprises a lock hook, a lock cylinder, a rotating blade, a fixed blade, a lock bolt and a lock body, wherein the rotating blade and the fixed blade are alternatively mounted in the lock cylinder, and the fixed blade is fixed on the lock cylinder. The cam lock is characterized in that the rotating blade is provided with symmetrical arc-shaped grooves. Since the structure of the rotating blade is changed, when other objects are used for twisting the blade, the rotating blade runs idly, and the lock can not be unlocked, thereby guaranteeing the safety of the lock. Meanwhile, the processing precision requirement is lowered and material consumption is reduced, and therefore, the rate of finished products is improved, and the cost of the lock is lowered.

Description

The page or leaf mortice lock that a kind of lock core can dally

Technical field

The page or leaf mortice lock that a kind of lock core can dally relates to the field of page mortice lock, is applicable to the situation that prevents violence damage page or leaf mortice lock lock gall and unblank especially.

Background technology

The kind of lock is more, cylinder lock, page or leaf mortice lock, electronic lock are arranged, shake control lock, magnetic padlock etc., the wherein cylinder lock of more use and a page or leaf mortice lock, page or leaf mortice lock rotate page or leaf sheet 2 and many fixation leafs 4, locking bolt 5, lock body 6, key 7 etc. by latch hook 1, lock gall 3, many and form; Lock gall is fixed in the lock body opening, rotate page or leaf sheet and fixation leaf and respectively be contained in composition lock core in the lock gall, fixation leaf is fixed on the lock gall, each rotates on the page or leaf sheet the deep-slotted chip breaker 12 (Fig. 3) that can hold locking bolt, the position of deep-slotted chip breaker 12 on circumference is inequality on the different rotation page or leaf sheets, locking bolt 5 is contained between the groove 11 of lock body 6 and lock gall 3, because locking bolt is partially submerged in the lock body groove 11, so lock gall can not arbitrarily rotate, lock does not just leave, and has only the key turns of using page or leaf sheet, locking bolt is fallen into rotate the deep-slotted chip breaker 13 of page or leaf sheet and leave lock body, at this moment, key rotates lock gall and unblanks.

The rotation page or leaf sheet 9 of old page or leaf mortice lock (Fig. 2) has a winglet 10 on the limit of circumference, winglet is stretched over the opening 8 on the lock gall circumference, when rotating the rotation of page or leaf sheet, winglet can be subjected to the opening restriction on the lock gall circumference, can only be with the key turns certain limit so rotate the page or leaf sheet.But, the lawless person, do not having under the situation of former lock key, adopt other object of non-former lock key to insert keyhole, the page or leaf sheet is rotated in violence, reach: (1) fractures the winglet on page sheet or is out of shape and leaves opening 8 on the lock gall circumference, thereby rotates the page or leaf sheet and can be rotated further and allow locking bolt 5 fall into to rotate the deep-slotted chip breaker 12 of page or leaf sheet and leave lock body 6, and lock is opened.(2), make locking bolt 5 be embedded into page sheet or locking bolt is embedded by the page or leaf sheet, reach the purpose of illegally unblanking.

The utility model content

A kind of lock core that the utility model proposes page or leaf mortice lock that can dally its objective is to prevent to unblank or destroy lock with other object insertion keyhole violence of non-former lock key.

The technical solution adopted in the utility model is: change the structure of rotating the page or leaf sheet, when making other object insertion keyhole rotation of non-former lock key, rotate the idle running of page or leaf sheet, thereby do not drive lock, can not destroy lock.

The page or leaf mortice lock that a kind of lock core of the present utility model can dally, comprise latch hook, lock gall, rotation page or leaf sheet, fixation leaf, locking bolt and lock body, rotate page or leaf sheet and fixation leaf and respectively be contained in the lock gall, fixation leaf is fixed on the lock gall, it is characterized in that the described deep-slotted chip breaker that the page or leaf sheet has symmetry that rotates.

The page or leaf mortice lock that above-described a kind of lock core can dally is characterized in that described rotation page or leaf sheet has 1-12 spare.

The page or leaf mortice lock that above-described a kind of lock core can dally is characterized in that the described deep-slotted chip breaker that rotates the symmetry of page or leaf sheet is a pair of.

The utility model is owing to changed the structure of rotating the page or leaf sheet, when other object twisting page or leaf sheet of non-former lock key, there not be fixing winglet owing to rotate the page or leaf sheet, so all the deep-slotted chip breaker that rotates on page sheet can not be aimed at locking bolt, so, locking bolt still is partially submerged in the lock body groove, so lock gall can not rotate, can not be opened so lock, but, a rotation page or leaf sheet can rotate in the same old way and become idle running, does not also destroy the structure of page or leaf sheet and lock simultaneously, has guaranteed the safety of lock.Do not have winglet owing to rotate a page sheet again, reduced requirement on machining accuracy and reduced consumptive material, thereby improved yield rate and reduced the cost of locking.

Among the figure: latch hook 1, rotate a page or leaf sheet 2, lock gall 3, fixation leaf 4, locking bolt 5, lock body 6, key 7, lock gall opening 8, old rotation page or leaf sheet 9, winglet 10, groove 11, deep-slotted chip breaker 12.

The specific embodiment

Now this programme is described with specific embodiment.Fig. 1,3,4,5 have shown the structure of the page or leaf mortice lock that a kind of lock core can dally; The component of the utility model page or leaf mortice lock have mainly comprised: latch hook 1, a rotation page or leaf sheet 2, lock gall 3, fixation leaf 4, locking bolt 5, lock body 6 and key 7.Lock gall uses dowel fixes in lock body opening, locking bolt is contained between the groove 11 of lock body and lock gall, rotate page or leaf sheet and fixation leaf and respectively be stacked in composition lock core in the lock gall, fixation leaf 4 (Fig. 5) is fixed on the lock gall 3, there are the groove and the center that can hold locking bolt that circular hole is arranged on it, each rotates on the page or leaf sheet two symmetrical deep-slotted chip breakers 12 that can hold locking bolt, and the position of deep-slotted chip breaker 12 on circumference is inequality on the different rotation page or leaf sheets.

Since this example the periphery of rotation page or leaf sheet on the deep-slotted chip breaker of two symmetries is arranged, so saved uncaging time.
