Embodiment 1

[0027] Such as Figure 1-Figure 3 As shown, this embodiment includes: a resetting device a for delaying time and a locking device b connected to it for limiting the number of times of unlocking, which is arranged on the side of the coded lock opposite to the coded gear shaft 0, wherein: the locking device b is connected with password gear c on password gear shaft 0.

[0028] Such as image 3 with Figure 8 As shown, the locking device b includes: a guide rod 4 with several fixed claws 3 and a baffle plate 16, and elastic buttons 5 and guide grooves 1 located at both ends thereof and coaxially arranged, wherein: the fixed claws 3 is in contact with the corresponding cipher gear c on the cipher gear shaft 0, and the side where the guide rod 4 is in contact with the guide groove 1 is provided with a positioning pin 2.

[0029] The elastic button 5 includes: a spring 6 connected to the end of the guide rod 4 and a button 7 connected to the spring 6. When the button 7 is pressed...

Abstract

The invention discloses a times-limited mechanical coded lock in the technical field of daily living articles. The mechanical coded lock comprises a resetting device and a dead lock device, wherein the resetting device is arranged in the coded lock, opposite to one side of a code gear shaft, and used for delay, and the dead lock device is connected with the resetting device, used for limiting unlocking times, and connected with code gears on the code gear shaft. According to the coded lock, a purpose of limiting the unlocking times of the coded lock is achieved by adding an embedded structure, so that the possibility of decoding the coded lock in unit time can be reduced, and the use safety of the coded lock can be improved.

Description

technical field [0001] The invention relates to a lockset in the technical field of daily necessities, in particular to a mechanical combination lock with a limited number of times. Background technique [0002] Combination locks are suitable for most of the fields that require application locks in daily life, work and study because of their simplicity and compactness. The principles of existing dial-type coded locks are all similar: the coded lock restricts the release of the lock cylinder by the coded dial, that is, unlocks. The password dial is divided into ten equal parts, corresponding to passwords 0 to 9, and there is a groove on the inner circle of the password dial, which corresponds to a number on the dial, that is, the password. When all the passwords are dialed to the predetermined position, all the grooves are arranged in a line, and at this moment, the lock cylinder can be released through the passage formed by the grooves, so as to achieve the purpose of unloc...
