Description

Anti-theft safety spring padlock

The utility model relates to the cylinder lock that uses screw key, specifically is meant a kind of burglary insurance spring padlock.

The locking bolt of at present all common spring padlocks have very long one section be exposed to outside, give the robber with opportunity, often make padlock be prized, be cut and be sawed, so that lock is by pirate of the open.

At the above-mentioned defective of existing spring padlock, the purpose of this utility model can prevent the burglary insurance spring padlock being prized, cut and sawed effectively thereby provide a kind of locking bolt is stashed as far as possible.

Solution of the present utility model is, it still has lock core and lock core body, having lock core marble hole on the lock core and the tip pellet shot from a slingshot is being housed in the hole, inwardly have the keyhole that is connected with lock core marble hole from the lock core end, on the lock core body, have the body pellet shot from a slingshot hole that aligns mutually with lock core marble hole, and the cylinder pellet shot from a slingshot outwards is housed successively in the hole, spring and pellet shot from a slingshot port lid, in the lock core body, be inserted with and stretch to the external locking bolt that is Jiong shape of cover, feature part of the present utility model is, locking bolt stretches to the external front side of lock core cover, the periphery of lock core body and locking bolt is with the lock box that is connected mutually with the lock core body, has the narrower snap close mouth that aligns the locking bolt front portion at the leading flank of lock box; On the lock core body, have the location pellet shot from a slingshot hole parallel, location pellet shot from a slingshot, spring and pellet shot from a slingshot port lid outwards are housed in the hole successively, and the location pellet shot from a slingshot puts in the axial location of offering on the lock core and sagittal plane spacing rotation pellet shot from a slingshot hole with body pellet shot from a slingshot hole; Also have that interconnect and parallel with a body pellet shot from a slingshot hole lock core automatic homing spring eye on lock core body and lock core, lock core automatic homing spring and spring port lid outwards are housed in the hole successively, the front end of spring and lock core be apical grafting mutually; The afterbody cunning of Jiong shape locking bolt is inserted in the locking bolt hole of offering lock core body front portion, in the middle of the locking bolt hole is jacking locking bolt spring eye, be equipped with and locking bolt tail end face the jacking locking bolt spring and the spring port lid of apical grafting mutually successively the below of locking bolt in the hole, in the hole top of locking bolt be equipped be connected mutually with locking bolt and stretch out the outer button of lock box perforate; Lock core hole in the lock core body is connected with the locking bolt hole, and the lock core front end has pruned vertically one and the arc tenon of formation.

The utility model with said structure, the snap close mouth that the snap close that during use use occasion is had injects lock box aligns mutually with the locking bolt front portion, presses the button with hand, in the hole of the anterior reeve of locking bolt snap close lock is locked.At this moment, the locking bolt afterbody will slip over the arc tenon of lock core front end, and lock core will rotate certain distance under the power effect of lock core automatic homing spring, makes lock core marble hole align mutually with body pellet shot from a slingshot hole, so the cylinder pellet shot from a slingshot in the body pellet shot from a slingshot hole enters in the lock core marble hole lock core is tacked, the arc tenon at lock core front end place is also done the rotation of certain distance with lock core, its string will be vertical with the central axis in locking bolt hole, thereby blocks upwards playback of locking bolt, the openhanded button of opening, lock still is in blocking.When injecting the keyhole of lock core with key, the cylinder pellet shot from a slingshot is withdrawed from from lock core marble hole, (this moment is because axial location on location pellet shot from a slingshot and the lock core and sagittal plane spacing are rotated the position-limiting action in pellet shot from a slingshot hole to reverse lock core with the direction of key lock core direction of rotation towards with locking the time again, can only reverse lock core towards this rightabout with key), make the arc tenon at lock core front end place will do the rotation (rotation distance is identical with the width that axial location and sagittal plane spacing are rotated the pellet shot from a slingshot hole) of unidirectional certain distance with lock core, the string of arc tenon will with the central axes in locking bolt hole, and in the locking bolt hole, get out of the way a straight way, make that locking bolt can be under the power effect of jacking locking bolt spring, driving button pops up together, thereby make lock be in opening, the locking bolt front portion is withdrawed from from the hole of snap close.At this moment, lock core automatic homing spring is compressed, but because locking bolt has blocked arc tenon and promptly blocked lock core, makes the lock core can not automatic homing; Since the tip pellet shot from a slingshot in the lock core marble hole with the cylinder pellet shot from a slingshot mistake in the body pellet shot from a slingshot hole position, and the tip pellet shot from a slingshot is uneven in length, makes key not extract out from lock core, but owing to locate the effect of pellet shot from a slingshot, when taking out key, will not extract lock core vertically out.

The utility model hides us with lock box with lock core body and locking bolt; not only specious; the more important thing is pellet shot from a slingshot port lid and spring port lid are not exposed; and locking bolt has only extremely short part to expose; snap close is injected after the bonnet lock hole; just can accomplish basically that locking bolt has not exposed; thereby can prevent picking lock effectively; cut malfeasances such as lock and saw lock; and lock box is to the protection of lock; prolonged the application life of lock, this just can protect the safety of huge numbers of families and communal facility reliably, safeguards the stable of society; this lock is easy to realize on making just in the structural improvement of spring padlock now.

Below in conjunction with drawings and Examples the utility model is further specified.
