Problems solved by technology
Since the battery should be placed in the safe to ensure power supply when not in use, it is necessary to replace the battery frequently, which is not only a waste of resources, but also after the battery is dead, the safe will not be able to be opened, and a spare key must be used. If the spare key In the absence of the lock, it will cause trouble to the user, and the lock cylinders of the prior art are all circular, so it is relatively weak in dealing with the technical opening of thieves.

Embodiment Construction
[0010] The accompanying drawings have shown the structure of the present invention and its embodiments, and describe the relevant details of its embodiments below in conjunction with the accompanying drawings. A lock hole 5 is provided, and the lock core 12 is non-rotatably arranged in the lock case 1, that is, the cross section of the lock core 12 is a cross section of a geometric shape other than a circle, such as a quadrangle, and the lock case 1 The cross-sectional shape of the inner contour matches the outer contour of the lock core 12, so that the lock core cannot rotate, which increases the difficulty of technical opening and improves the anti-theft performance of the lock core; the dead bolt 2 is connected with the slide block 16, and the slide block 16 The block 16 is connected to the rotating shaft 10 by transmission, that is, the rotating shaft 10 is provided with a handle knob 20, the handle knob 20 is provided with a gear 21, the slider 10 is provided with a rack 2...

The invention discloses a safe box lock which comprises a lock case (1), a lock cylinder (12) and a bolt (2). A lock hole (5) is formed in the lock cylinder; the bolt is connected with a sliding block (16); and the sliding block is in transmission connection with a rotating shaft (10). The safe box lock is characterized in that the lock cylinder is arranged in the lock case in a way that the lock cylinder can not rotate; upper and lower special-shaped marbles matched with the lock hole and a shifting sheet are arranged in the lock cylinder; the upper and lower special-shaped marbles are correspondingly provided with upper and lower side bumping posts; the special-shaped marbles are provided with grooves matched with the side bumping posts; the other end of the lower side bumping post is connected with a moving block (11); the other end of the moving block is connected with a second elastic device; a negative terminal is arranged in the lock case; the second elastic device is connected with a positive terminal; the negative and positive terminals are connected with a power supply; and the power supply is connected with an electromagnetic valve (17). Therefore, only when a model key is correctly inserted into the safe box lock, the moving block moves upwards to touch the negative terminal, the power supply can be switched on, so that resources are saved.
Description
technical field [0001] The invention relates to a safe lock, in particular to a safe lock which is powered only when in use. Background technique [0002] The use of safe is more and more general in daily life, and in the prior art, safe is all to be loaded into electric storage device such as battery, makes safe energize. Since the battery should be placed in the safe to ensure power supply when not in use, it is necessary to replace the battery frequently, which is not only a waste of resources, but also after the battery is dead, the safe will not be able to open, and a spare key must be used. If the spare key Under the absent situation, will cause trouble to the user, and the lock cylinder of prior art is all circular, therefore, is comparatively weak in the aspect of technical opening of coping with thieves. Contents of the invention [0003] In view of the problems existing in the known technology, the technical problem to be solved by the present invention is to p...
