Special delay closing lock for finance

Abstract

The invention provides a special delay closing lock for finance, and belongs to the field of anti-theft product manufacturing. The lock comprises a face plate, a delay mechanism and a clamping groove;the clamping groove is arranged at the edge of the face plate; a lock cylinder capable of being opened by a key and rotating along with the key is arranged in the middle of the face plate, and a magnet is fixed to the edge of the lock cylinder; the delay mechanism is arranged on the face plate, the inner end of a piston of the delay mechanism faces the lock cylinder, and a spring bolt capable ofsynchronously sliding along with the piston is arranged on the delay mechanism; and the lock cylinder rotates to enable the magnet to be close to and correspond to the piston, and the piston drives the spring bolt to be separated from the clamping groove. According to the lock, the lock cylinder is rotated to a certain preset angle, so that the magnet on the lock cylinder is close to and attractsthe piston, and the piston moves slowly to open the spring bolt; and due to the delay characteristic of the delay mechanism, the spring bolt can be smoothly opened by knowing the position of the delaymechanism in advance, so that the anti-theft performance is greatly improved.

Description

technical field [0001] The invention relates to a lock manufacturing technology, in particular to a delay-closing lock dedicated for finance, and belongs to the technical field of anti-theft products manufacturing. Background technique [0002] A pin tumbler lock, also known as a pin tumbler lock, bead lock, bolster lock or pin bolt lock, is one of the most common lock structures. The principle is to use multiple cylindrical parts of different heights (called lock springs, pins or beads) to lock the lock cylinder. When the correct key is put in, each lock bolt is pushed to the same height, and the lock cylinder is released. [0003] The existing tumbler locks are simple in principle and poor in anti-theft performance. When performing technical opening, they can be opened in a short time. The complexity of the arrangement and the installation of a self-locking device at the entrance, but because the principle has not changed, it can still be opened when it is technically op...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a new delayed closing lock dedicated to finance. By designing a delay mechanism corresponding to the opening angle of the lock core, the lock bolt can be opened by adjusting the rotation angle of the lock core to solve the problem of locks being lost or damaged in the prior art. Technical problem of loss of anti-theft function during malicious copying
