Technical Field
[0001] The utility model belongs to the technical field of locks and relates to a password lock box. Background Technique
[0002] At present, the common password locks on the market are divided into two types: mechanical password locks and electronic password locks. The principle of a mechanical password lock is to use a turntable to rotate several discs or cams inside the lock; some mechanical password locks are to rotate a set of several dials engraved with numbers to drive the mechanism inside the lock. The internal structure of this kind of mechanical password lock is relatively complex, with many components and high processing costs.
[0003] Moreover, by rotating the digital turntables one by one, when the correct number is reached, some password locks will make a small "click" sound or there will be a slight looseness, and this kind of password lock is very easy to be cracked by outsiders. Content of the Utility Model
[0004] The purpose of the utility model is to address the above problems existing in the existing password locks and propose a password lock box with a simple structure.

The rotating shaft is rotated so that the abutting surface moves to be parallel and fitted with the inner side surface of the notch, and the push plate extends out of the box body to realize locking; the rotating shaft is rotated so that the inner side surface of the notch is gradually separated from the abutting surface until the abutting surface completely exits outside the notch, and the push plate translates into the box body to realize unlocking.
[0009] In the above-mentioned password lock box, two locking hooks are fixedly arranged on the push plate. The two locking hooks are located outside the box body, and the two locking hooks translate synchronously with the push plate inside the box body for unlocking or locking; a pin is fixedly arranged on the locking hook, and the end of the return spring is hooked on the pin for pulling the push plate to translate.
[0010] In the above-mentioned password lock box, the password gear disk includes a gear shaft and a password disk arranged on the gear shaft. A number of digits are engraved on the password disk, and each digit is evenly spaced along the circumferential direction of the password disk in sequence.
[0011] In the above-mentioned password lock box, the password disk is detachably arranged on the gear shaft. A number of positioning grooves are formed on the gear shaft, and the number of positioning grooves is evenly spaced along the circumferential direction of the gear shaft. The number of positioning grooves is the same as the number of digits on the password disk. A positioning hole is formed on the password disk, and a number of positioning protrusions corresponding to the positions of the positioning grooves are fixedly arranged on the inner wall of the positioning hole.
[0012] In the above-mentioned password lock box, a ratchet wheel is fixedly arranged on the gear shaft. The number of teeth of the ratchet wheel is the same as the number of digits on the password disk. A number of elastic members corresponding to the positions of the password gear disks are also arranged in the box body. The elastic members are inserted into the ratchet grooves of the ratchet wheel and elastically press against the ratchet wheel.
[0013] In the above-mentioned password lock box, a turntable is fixedly arranged on the gear shaft. The above-mentioned limit bayonet is arranged on the turntable. A number of card slots are also formed on the turntable. Each card slot and the limit bayonet are evenly spaced along the circumferential direction of the password disk and correspond to the positions of the digits on the password disk.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. When all the password gear disks are rotated to the in-place position according to the set password, when the opening positions of the limit bayonets on each password gear disk correspond to the positions of the limit blocks, at this time, the push plate is translated inwards by rotating the rotating shaft, so that each limit block is inserted into the limit bayonet to realize unlocking. Continuing to rotate the rotating shaft, the push plate is translated outwards by pulling the return spring to realize locking. The utility model adopts a pure mechanical structure to realize unlocking and locking, with a simple structure and low cost;
[0016] 2. When all the password gear disks are rotated to the in-place position according to the set password, remove the password gear disk, rotate it by a certain angle and then reinstall it, and a new password can be set. The utility model is convenient and fast to change the password;
[0017] 3. Since there is a certain gap between the limit block and the limit bayonet, when one of the password dials rotates to the correct position, the push block will have a slight looseness. To prevent outsiders from cracking the password and unlocking the lock by rotating the password dials one by one, several card slots are provided on the turntable, and no matter which number position the password dial rotates to, the same effect can be achieved to prevent outsiders from cracking the password.

Detailed Description of the Preferred Embodiment
[0030] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.
[0031] As Figures 1 to 4 shown, a password lock box of the present utility model includes a box body 1 and a push plate 2. The push plate 2 is slidably arranged in the box body 1. A rotating shaft 3 is rotatably arranged on the box body 1, and the push plate 2 abuts against the rotating shaft 3. As Figure 5 and Figure 6 shown, a plurality of password gear disks are rotatably arranged on the box body 1. A limiting bayonet 4 is opened on the password gear disk. A plurality of limiting blocks 5 corresponding to each limiting bayonet 4 one by one are fixedly arranged on the push plate 2. When the opening positions of the limiting bayonets 4 on each password gear disk correspond to the positions of the respective limiting blocks 5, the rotating shaft 3 is rotated. The rotating shaft 3 pushes the push plate 2 to translate, so that each limiting block 5 is inserted into or withdrawn from the limiting bayonet 4 to achieve unlocking or locking.
[0032] The password lock box further includes a return spring for pulling the push plate 2 to translate in the direction of extending out of the box body 1, so that the push plate 2 always abuts against the rotating shaft 3. Two locking hooks 8 are fixedly arranged on the push plate 2. The two locking hooks 8 are located outside the box body 1. The two locking hooks 8 translate synchronously with the push plate 2 inside the box body 1 for unlocking or locking. A pin 9 is fixedly arranged on the locking hook 8. The end of the return spring is hooked on the pin 9 for pulling the push plate 2 to translate.
[0033] As Figure 7 and Figure 8 shown, a notch 6 is opened on the rotating shaft 3. The push plate 2 has an abutting surface 7. The rotating shaft 3 is rotated to make the abutting surface 7 move to be parallel and in contact with the inner side surface of the notch 6. The return spring pulls the push plate 2 to extend out of the box body 1 to achieve locking. The rotating shaft 3 is rotated to gradually separate the inner side surface of the notch 6 from the abutting surface 7 until the abutting surface 7 completely exits outside the notch 6, and the push plate 2 translates into the box body 1 to achieve unlocking.
[0034] As Figures 9 to 11 shown, the password gear disk includes a gear shaft 10 and a password disk 11 arranged on the gear shaft 10. A plurality of numbers are engraved on the password disk 11. Each number is evenly spaced along the circumferential direction of the password disk 11. The password disk 11 is detachably arranged on the gear shaft 10. A plurality of positioning grooves 12 are opened on the gear shaft 10. The plurality of positioning grooves 12 are evenly spaced along the circumferential direction of the gear shaft 10. The number of the positioning grooves 12 is the same as the number of the numbers on the password disk 11. A positioning hole is opened on the password disk 11. A plurality of positioning protrusions 13 corresponding to the positions of the respective positioning grooves 12 are fixedly arranged on the inner wall of the positioning hole.
[0035] When all the password dials rotate to the in-place position according to the set password, the corresponding one is the old password at this time. Remove the password dials, rotate them by a certain angle and then reinstall them to set a new password. The password replacement of the present utility model is convenient and fast.
[0036] A ratchet wheel 14 is fixedly arranged on the tooth shaft 10. The number of teeth of the ratchet wheel 14 is the same as the number of digits on the password dial 11. A plurality of elastic members corresponding to the positions of each password dial are further arranged in the box body 1. The elastic members are inserted into the ratchet slots of the ratchet wheel 14 and elastically press against the ratchet wheel 14. Each password dial 11 of the present utility model is equipped with an independent ratchet wheel 11 and an elastic member. The advantage of such a design is that the sound of each click of the elastic member leaning against the ratchet wheel 11 is of the same weight, avoiding outsiders from cracking the password.
[0037] A turntable 15 is fixedly arranged on the tooth shaft 10. The above-mentioned limit bayonet 4 is arranged on the turntable 15. A plurality of card slots 16 are further opened on the turntable 15. The card slots 16 and the limit bayonet 4 are evenly spaced along the circumferential direction of the password dial 11 and correspond to the positions of the digits on the password dial 11. Since there is a certain gap between the limit block 5 and the limit bayonet 4, when one of the password dials 11 rotates to the correct position, the push block will have a slight looseness. In order to prevent outsiders from cracking the password and unlocking by rotating the password dials 11 one by one, a plurality of card slots 16 are arranged on the turntable 15. No matter which digit position the password dial 11 rotates to, the same effect is achieved, avoiding outsiders from cracking the password.
