Abstract

A leaf lock with an I-type rotation keyhole and an abnormal keyhole anti-prized piece pertains to the field of mechanical lock, which is especially suitable for doors and cars. By limiting the size of the hard material plugging into keyhole and arresting hard material from entering the keyhole, the leaf lock can prevent the keyhole from damage by tools and unlocking by hard material rotating leaf. Such a leaf lock comprises a lock body, a lock shell, a key ball, a leaf, a lock pin, a keyhole, a lock hook and a key; the leaf lock has advantages in that the leaf lock has the I-type rotation keyhole and abnormal keyhole anti-prized piece; consists of a keyhole (8), a spring (9), a friction ball (10) and an anti-prized piece (11); the I-type keyhole cooperates with lock shell (2); spring and friction ball are fixed inside the hole on the end face of keyhole; friction bal sticks out of the end face of keyhole while anti-prized piece is inside key ball (1) with the one side pressuring friction ball; and the anti-prized piece has a symmetrical salient (13) and a square corner (14).

Description

The hinge lock of a kind of H-shaped rotating spoon door and special-shaped keyhole pick-proof sheet

Technical field:

Utility model: the page or leaf mortice lock of a kind of I shape rotation spoon door and special-shaped keyhole pick-proof sheet, belong to the mechanical lock field, be suitable for especially on door and automobile, using.

Back of the body border technology:

The page or leaf mortice lock is the class in the lock, because of the page or leaf sheet that rotation is arranged is gained the name.Mainly, lock some by lock body, lock housing, spoon gall, hinge, spoon door, lock hook and key form for it.Lock housing is fixed in the lock body circular hole, and spoon gall is contained in the lock housing circular hole, and hinge is contained in the spoon gall, lock hook connects core, every hinge periphery is jagged, and lock is placed between with it corresponding the spoon gall face of cylinder elongated slot and lock housing inner cylinder face half slot, and spoon gall and hinge all can be rotated.

The operating principle of page or leaf mortice lock is (Fig. 1,2): locking state is shown in Figure 1 as illustrating: at this moment, lock (4) embeds between the elongated slot (3) and lock housing (2) face of cylinder half slot (5) of spoon courage (1), has stoped the rotation of spoon courage and lock hook, is in locking state.Unlocking condition is shown in Figure 2 as illustrating: rotate page or leaf sheet (7) with spoon, when the breach (6) of all pages sheet is aimed at spoon courage (1) elongated slot, lock (4) enters between a spoon courage (1) elongated slot and the page or leaf sheet breach (6), lock breaks away from lock housing (2) half slot (5), be rotated further key, page or leaf sheet breach rotates by the lock hook that lock drives spoon courage and binding with it, so lock is opened.

The page or leaf mortice lock of this structure has following shortcoming.The one, can destroy the spoon door by tool using (as boring).The 2nd, can rotate hinge with brute force, hinge can produce slight distortion, adds the gap (tolerance) of lock body, lock housing, spoon gall, hinge, and like this, hinge is forced to rotate, and lock is entered between lock core elongated slot and the hinge breach, reaches the purpose of unblanking by force.

Summary of the invention:

The utility model proposes the hinge lock of a kind of H-shaped rotating spoon door and special-shaped keyhole pick-proof sheet, its objective is: prevent that tool using from destroying the spoon door and preventing that effectively the powerful hinge of rotating of hard thing from unblanking.

The hinge lock of a kind of H-shaped rotating spoon door and special-shaped keyhole pick-proof sheet, the scheme of employing is: the one, the size that restriction enters the hard thing of keyhole makes its torsion strength be lower than the deformation force of hinge, and before hinge there was not distortion, brute force was just destroyed hard thing.The 2nd, stop hard thing to enter keyhole and rotate hinge, thereby can not unblank.

The hinge lock of a kind of H-shaped rotating spoon door and special-shaped keyhole pick-proof sheet comprises lock body, lock housing, spoon gall, hinge, lock, spoon door, lock hook and key; It is characterized in that having the rotating spoon door of I shape and the pick-proof sheet of special-shaped keyhole, it is made up of spoon door, spring, steel ball and pick-proof sheet; Spoon door and lock housing circular hole movingly, the keyhole of spoon door is I shape, spring and steel ball are fixed in the hole of spoon door end face, the outstanding spoon door of steel ball end face, the pick-proof sheet is installed in the key base hole, and it simultaneously compresses steel ball, and the square keyhole of pick-proof sheet has symmetrical salient angle and corner.

The spoon door is through Overheating Treatment, and its hardness surpasses drill bit.

The salient angle of described square keyhole is 60 degree angles.

The utility model has greatly limited with hard thing and has entered the possibility that keyhole is unblanked owing to adopted H-shaped rotating spoon door and special-shaped keyhole pick-proof sheet.In this way by force, hard thing will be twisted off; Or hard thing can not can only rotate along with the spoon door by the keyhole of pick-proof sheet, can not rotate a page sheet and unblank.Because spoon door hardness surpasses drill bit, thereby can not destroy the spoon door with drill bit and unblank.

Spoon courage 1, lock housing 2, elongated slot 3, lock 4, half slot 5, page or leaf sheet breach 6, page or leaf sheet 7, spoon door 8, spring 9, steel ball 10, pick-proof sheet 11, key 12, salient angle 13, corner 14.

The specific embodiment:

Now with specific embodiment explanation this programme.

Fig. 4,5,6 has shown assembly relation and the structure of spoon door, spring, steel ball and pick-proof sheet.Spoon courage 1, lock housing 2, page or leaf sheet 7, spoon door 8, spring 9, steel ball 10, pick-proof sheet 11, key 12, salient angle 13, corner 14.

Spoon gall 1 is contained in lock housing 2 circular holes, and hinge 7 is contained in the spoon gall, and spoon gall and hinge all can be rotated.Spoon door and lock housing circular hole movingly, the keyhole of spoon door is I shape, spring and steel ball are fixed in the hole of spoon door end face, the outstanding spoon door of steel ball end face, the pick-proof sheet is installed in the key base hole, and it simultaneously compresses steel ball, and square keyhole has 60 symmetrical degree salient angle 13 and corners 14.The spoon door uses steel manufacturing, Quenching Treatment, hardness to reach Rockwell hardness greater than more than 65.

Fig. 3 expresses the hinge lock assembling line map of H-shaped rotating spoon door and special-shaped keyhole pick-proof sheet.

This routine hinge lock construction is simple, and is convenient by dress, can effectively prevent illegal and violence is unblanked.
