Description

Reinforcing structure of a safe lock

technical field

The invention belongs to a safe lock, and in particular relates to a reinforcement structure of a safe lock.

Background technique

Safes are companies, all walks of life and personal safes for depositing valuables and money. At present, there are products of multiple different structures, and no matter that kind of safes, they have their shortcomings. Some of these safes have complex structures, some are inconvenient to use, some are easily damaged, and the anti-theft performance is poor. There are 90% safe structures on the market that are easy to damage.

As shown in Figures 1 and 2, most of the safe locks on the market rely on the lock cylinder 9 arranged on the cabinet door 2 to drive the plectrum 4 to withstand the dead bolt 5 matched with the cabinet body 1 in the locked state. To prevent the safe from being opened, if the plectrum 4 withstands the dead bolt 5, the turntable 12 arranged on the cabinet door 2 cannot drive the dead bolt 5 arranged on the connecting rod 6 to move away from the cooperation with the cabinet body 1 by rotating the gear 7 At the same time, the connecting rod 6 cannot drive the lock tongue 5 on the upper and lower lock rods 8 and 11 to move and disengage through the cooperation of the pin 10 with the chute hole 601 on the upper lock rod 8 and the chute hole 1101 on the lower lock rod 11 respectively. With the state of cooperation with the cabinet body 1, the safe is in a locked state, otherwise, the safe can be opened by rotating the turntable 12. This kind of safe that adopts the plectrum structure often does not have a protective effect on the lock core 9. The lock core 9 is only fixed on the cabinet door 2 by a fixed plate 3, and a large part is exposed outside the cabinet door. During violent destruction, as long as the fixed plate 3 is slightly loose or falls directly, and the cooperation between the paddle 4 and the lock tongue 5 becomes loose or deviates, then as long as the turntable 12 is twisted, the safe door 2 will open naturally, and the entire safe will Lost the anti-theft function. Therefore, be necessary to develop the better safe lock of better anti-theft performance.

Contents of the invention

The object of the present invention is to provide a reinforcement structure of a safe lock with reasonable structure and better anti-theft performance aiming at the defects of the prior art.

The technical scheme that realizes the object of the present invention adopts is as follows:

The reinforcement structure of the safe lock provided by the present invention comprises a cabinet body, a cabinet door arranged on the cabinet body, a rotatable lock cylinder arranged on the cabinet door and a deadbolt matched with the cabinet body, the cabinet door A lock cylinder protection device that wraps the tail of the lock cylinder is fixed on the top, and the lock cylinder protection device is provided with a lock rod that is connected with the lock tongue and can move back and forth. The cylindrical connecting piece is provided with a circular arc-shaped first groove matching the outer diameter of the lock rod, and the locking rod is provided with an outer diameter matching the lock cylinder or the connecting piece connected to the tail of the lock cylinder. arc-shaped second groove.

The lock cylinder protection device includes a reinforcement part wrapping the tail of the lock cylinder and a protective cover covering the outside of the reinforcement part, and the lock rod passes through the reinforcement part and the protection cover to connect with the lock tongue , the protective cover and the reinforcing part are fixed on the cabinet door by screws.

Beneficial effect

In the present invention, a protective device is installed at the tail of the lock cylinder, and this device can firmly withstand the tail of the lock cylinder to prevent the outside world from beating inwardly with violence. The tail of the lock cylinder is in contact with the protection device, so it cannot be destroyed. Under the action of the protection device for the lock cylinder, the left and right swings of the lock cylinder will also be firmly fixed. The protection device can also ensure that the locking bar is always in a horizontal position, which can reduce the fit gap between the parts. When the lock cylinder is subjected to external violence, the lock cylinder will withstand the lock rod, and the lock rod will withstand the dead bolt, which greatly enhances the strength of the lock cylinder and improves the anti-theft performance of the safe lock.

The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

detailed description

See Fig. 3 to Fig. 8, the reinforcement structure of the safe lock that the present invention provides, comprises cabinet body 1, the cabinet door 2 that is located on the cabinet body 1, is located at the rotatable lock cylinder 9 on the cabinet door 2 and with all The lock tongue 5 matched with the cabinet body 1, the back side of the cabinet door 2 is fixed with a lock cylinder protection device 13 wrapping the tail of the lock cylinder 9; The reinforced part 1302 wrapped at the tail and the protective cover 1301 covered outside the reinforced part 1302, the protective cover 1301 and the reinforced part 1302 are fixed on the cabinet door 2 by screws 1303; the lock cylinder protection device 13 is provided with The lock tongue 5 is connected to a lock bar 14 that can move back and forth, and the lock bar 14 passes through the reinforcement part 1302 and the protective cover 1301 to connect with the lock tongue 5; An arc-shaped first groove 901 matching the diameter of the lock cylinder 9, and a second arc-shaped groove 1401 matching the outer diameter of the lock cylinder 9 is provided on the lock rod 14 .

As shown in Figure 9, a cylindrical connecting piece 902 can also be connected to the tail of the lock cylinder 9, and a circular arc-shaped first groove 901 matching the outer diameter of the locking rod 14 is provided on the cylindrical connecting piece 902, and the locking rod 14 is provided with an arc-shaped second groove 1401 matching the outer diameter of the connecting piece 902 connected to the tail of the lock cylinder 9 .

See Fig. 3 and Fig. 4, after the safe is installed with the reinforcing structure of the present invention, the lock core 9 is completely wrapped in the lock core protection device 13, which can fix the lock core 9 in all directions. When unlocking, as shown in Figure 5 and Figure 6, the opening direction of the first groove 901 on the lock cylinder 9 and the second groove 1401 on the lock bar 14 just correspond, and they do not affect each other. 14 can move back and forth horizontally freely, and drive the connecting rod 6 to retreat by the turntable rotating gear 7 outside the cabinet door 2, and then drive the dead bolt 5 connected with the connecting rod 6 and the pin 10 on the connecting rod 6 to connect with the upper locking rod 8 respectively. The upper chute hole 601 and the chute hole 1101 on the lower lock bar 11 cooperate to drive the dead bolt 5 on the upper and lower lock bars 8,11 to move out of the matching state with the cabinet body 1, and open the safe.

When locking, first turn the turntable so that each dead bolt 5 is in a state matched with the cabinet body 1, and then rotate the lock core 90 degrees, as shown in Figures 7 and 8, at this moment the first groove 901 on the lock core 9 is aligned with the lock core 9. The opening direction of the second groove 1401 on the lock rod 14 is just misaligned and perpendicular to each other, the lock cylinder 9 is stuck in the second groove 1401 of the lock rod 14, and the lock rod 14 is limited by the lock core 9, which restricts the lock rod 14 to be horizontal. movement in the direction to achieve a locked state.
