Description

Safety angle blade lock

Technical Field

The invention relates to a lockset, in particular to a safety angle blade lock.

Background

The existing blade lock needs to be rotated for 180 degrees to unlock; the unlocking direction is ordered, customers easily neglect the direction problem when buying, and products can only be plugged in one direction; while the cumulative tolerance of the blade stack-up plagues production. In addition, the existing blade lock needs to pre-rotate a key, a blade password groove is matched with the key in the pre-rotation process, the blade groove is in a straight line at the moment, and the lock bolt falls down when the blade lock rotates, so that unlocking is realized; the use is relatively inconvenient.

Disclosure of Invention

The invention aims to provide a safe angle blade lock which has higher precision and freely adjustable unlocking direction and is convenient to produce.

In order to achieve the above object, the technical solution of the present invention is:

The invention relates to a safety angle blade lock, which comprises a lock shell, a plurality of blades, a lock cylinder, a baffle plate, a poking plate, a lock plunger spring, a nut and a key; the lock core gap is sleeved in the middle hole of the lock shell, the baffle plate and the poking plate are sequentially sleeved on the inner side section of the lock core, and the nut is fixedly screwed on the threaded column at the inner end of the lock core to fix the baffle plate and the poking plate on the lock core; the lock cylinder is of an integrated structure, a plurality of blade cabins are arranged on the lock cylinder, and openings of the blade cabins are opened along the radial direction and are arranged side by side at intervals; the middle part of each blade is provided with a through groove for a key to penetrate, the inner wall of the through groove is provided with a convex rib matched with the key, the outer wall of each blade is provided with a password groove, and a plurality of blades are respectively movably arranged in a plurality of blade bins of the lock cylinder; the lock bolt is movably arranged between the inner wall of the hole in the lock shell and the lock core, a lock bolt spring is arranged between the top surface of the lock bolt and the lock shell, the bottom surface of the lock bolt abuts against the blade, and the lock bolt can fall into the password groove on the outer wall of the blade; the key is inserted into the lock cylinder.

More than one groove is formed in the inner wall of the middle hole of the lock shell.

The insertion part of the key is provided with a long groove along the axial direction, the inlet of the long groove is arranged at the insertion end of the key, and the long groove is matched with the convex ribs on the blades, so that the convex ribs on the blades can slide in.

The long groove on the key is a snake track.

After the scheme is adopted, the invention has the following advantages:

1. because the invention adopts the integrated lock cylinder, the spacer is cancelled, and the blade bin is added on the lock cylinder, the problem of accumulated tolerance is solved, the accumulated tolerance is smaller, and the precision is higher.

2. The invention can unlock in different directions of 90 degrees or 180 degrees, the unlocking direction is freely adjusted, and the operation is more convenient.

3. The key adopts the long groove of the snake-shaped track, the snake-shaped track of the key is matched with the convex ribs on the blades, the blades can be initially rotated during insertion, unlocking is realized, and the structure is more reasonable.

4. The multi-directional plug can be realized only by adding the groove on the lock shell at the position where the key is required to be plugged, and the key plugging port can be customized.

5. The unlocking direction of the invention is set by the baffle plate, and the client can freely adjust.

The invention will be further described with reference to the drawings and the specific examples.

Detailed Description

As shown in fig. 1 to 4, the present invention is a safety angle blade lock, comprising a lock housing 1, a plurality of blades 2, a lock cylinder 3, a blocking piece 4, a pulling piece 5, a lock bolt 6, a lock bolt spring 7, a nut 8, and a key 9.

The lock cylinder 3 is sleeved in the middle hole 11 of the lock shell 1 in a clearance way, the baffle 4 and the poking plate 5 are sequentially sleeved on the inner side section of the lock cylinder 3, the nut 8 is fixedly screwed on the threaded column 31 at the inner end of the lock cylinder 3, and the baffle 4 and the poking plate 5 are fixed on the lock cylinder 3; the lock cylinder 3 is of an integral structure, and is provided with a plurality of blade cabins 32 (shown in fig. 5 and 6), wherein the openings of the blade cabins 32 are opened along the radial direction and are arranged side by side at intervals.

Referring to fig. 8, the middle part of the blade 2 is provided with a through groove 21 for a key to penetrate, the inner wall of the through groove 21 is provided with a convex rib 22 matched with the key, the outer wall of the blade 2 is provided with a password groove 23, and a plurality of blades 2 are respectively movably arranged in a plurality of blade bins 32 of the lock cylinder 3; the lock bolt 6 is movably arranged between the inner wall of the hole 11 in the lock shell 1 and the lock cylinder 3, a lock bolt spring 7 is arranged between the top surface of the lock bolt 6 and the lock shell 1, the bottom surface of the lock bolt 6 is abutted against the blade 2, and the lock bolt 6 can fall into the coded groove 23 on the outer wall of the blade 2.

Referring to fig. 9, the key 9 is inserted into the lock cylinder 3, the insertion portion of the key 9 is provided with an elongated slot 91 along the axial direction, the elongated slot 91 is a snake track 91, the preliminary rotation of the blade 2 can be realized during insertion, the entrance of the snake track 91 is provided at the insertion end of the key 9, the snake track 91 is matched with the ribs 22 on the plurality of blades 2, and the ribs 22 on the plurality of blades 2 can slide in.

If necessary, more than one groove 12 (as shown in fig. 7) can be formed on the inner wall of the hole 11 in the lock case 1.

The working principle of the invention is as follows:

When the key 9 is inserted, the convex ribs 22 of the blade 2 are matched in a rotating way along the snake-shaped track 91 of the key 9, the key 9 is rotated, the lock bolt 6 falls into the correct password groove 23 of the blade 2 under the action of the groove of the lock shell 1, the rotating radius of the lock bolt 6 is not larger than the inner diameter of the lock shell 1, and meanwhile, the key 9 drives the lock cylinder 3 to rotate, and the lock is unlocked after rotating for 90 degrees; the reverse rotation is 90 degrees, the lock bolt 6 is sprung up under the action of the lock bolt spring 7, when the key 9 is pulled out, the rail opening 92 of the key 9 divides the convex ribs 22 of the blades 2 into a straight line, thereby realizing the effect of messy codes of the blades 2, and at the moment, the rotation radius of the lock bolt 6 is larger than the inner diameter of the lock shell 1, so that locking is realized. The key 9 has a semicircular top surface, and the snake track 91 thereon enables the blade 2 to perform preliminary rotational movement to realize integral rotation.

The foregoing description is only illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, i.e., the equivalent changes and modifications to the invention as described in the claims and specification should be considered as falling within the scope of the invention.
