Description

Dial type cipher bolt mechanism

Technical Field

The utility model belongs to the technical field of the tool to lock, a dial formula password bolt mechanism is related to.

Background

The trick lock is the tool to lock, unlocks and locks through using a set of or multiunit password, owing to need not use the key in the use, has avoided the key to lose or the condition that the key damages the unable condition of unblanking that causes, receives consumer's liking, and the trick lock includes mechanical trick lock and electronic trick lock, and common mechanical trick lock includes button, carousel formula and dial plate formula, and common electronic trick lock includes button, scanning formula etc.. The mechanical coded lock adopts a mechanical structure to be switched on and off, is stable in structure, is not interfered by electromagnetism, and can be suitable for most use conditions.

Chinese patent document discloses a mechanical combination door lock [ application number: 201110157005.1, publication number: 102828659B ] a handle set, an unlocking set, a combination lock set and a number finding set are arranged on the shell set, the locking function of the combination door lock can be released by dialing the unlocking set under the condition that the unlocking set is matched with the combination lock set, and the combination lock set can push the sleeve to be separated from the corresponding character wheel by pressing the press button, thereby rotating the character wheel and resetting the code; the number searching group is abutted against the sleeves of the number lock group, and the original unlocking password can be obtained by the aid of the positioning pins of the number searching group extending into the number searching grooves of the corresponding sleeves. The coded lock can realize locking, unlocking, password changing, password retrieving and other operations.

Because the two ends of the sleeve elastic part, namely the spring, are respectively abutted against the lock column and the sleeve, the sleeve and the character wheel rotate together when the character wheel is rotated in the unlocking process, and the lock column can not rotate because the clamping part on the lock column is clamped in the catching groove of the transmission gear. When the print wheel at the lowest part rotates, the upper end of the spring is abutted against the sleeve and is easily rotated along with the sleeve, and the lower end of the spring is abutted against the lock column and is kept still, so that the spring is easily twisted, and the spring is easily damaged after being used for multiple times. After the spring damages, the separation takes place easily for sleeve and character wheel on the one hand, leads to the character wheel to rotate and can not drive the sleeve and rotate, arouses the unblock failure, and on the other hand leads to the lock post can not the downstream make the counterpoint lug on the sleeve deviate from between the counterpoint portion, arouses to lock the failure, leads to whole trick lock to use unstablely like this.

Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, provide a dial formula trick bolt mechanism, the technical problem of solution is how to improve the stability that dial formula trick lock used.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a dial formula password bolt mechanism, includes mount pad and bolt, the cover is equipped with on the bolt with the rotatable driver plate subassembly of bolt complex, the driver plate subassembly is installed on the mount pad, the rear end of driver plate subassembly is provided with first spring, a serial communication port, the mount pad rear end has back support frame, be provided with gliding after-fixing piece around can between first spring and the driver plate subassembly, the installation of after-fixing piece circumference location is on the mount pad, the both ends of first spring are supported respectively to lean on after-fixing piece and back support frame, under the effect of first spring the front end of after-fixing piece supports and leans on the driver plate subassembly.

When the password is found back, the reverse-side deflector rod is pulled forwards, the inserting plate 9 slides forwards, the bottom of the elastic bayonet lock 10 is separated from the accommodating groove 9a and is abutted against the front surface of the inserting plate 9, then the character wheel 4a is rotated, when the code finding groove 4b4 on the sleeve 4b is opposite to the elastic bayonet lock 10, the top of the elastic bayonet lock 10 is inserted into the code finding groove 4b4, the dial piece 4 is locked, the password is found, the front end of the bolt 2 can automatically pop up when the password is correct, and whether the password is correct or not is very convenient to determine. After the password is found back, the reverse-side shifting rod is shifted backwards, the inserting plate 9 slides backwards, the bottom of the elastic clamping pin 10 enters the accommodating groove 9a, the elastic clamping pin 10 is separated from the code finding groove 4b4 under the action of the top spring, the character wheel 4a is shifted again after the front end of the plug pin 2 is pressed, and the dial type password plug pin mechanism can be normally used.

In this dial formula password bolt mechanism, after-fixing block 6 can slide around, and after-fixing block 6 supports under the effect of first spring 7 and leans on rearmost sleeve 4b, make the setting of after-fixing block 6 can not influence the normal use of driving plate subassembly 3, make first spring 7 and driving plate subassembly 3 separation through setting up after-fixing block 6 simultaneously, and 6 circumference of after-fixing block are fixed on mount pad 1, the rotation that makes driving plate subassembly 3 can not drive first spring 7 and rotate, make the use of first spring 7 stable, the stability of using has been improved.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
