Puzzle lock body

Technical Field

The utility model belongs to the technical field of the lock, refer in particular to a trick lock body.

Background

The cipher lock is an intelligent one, and is a crystal product of computer information technology, electronic technology, mechanical technology and modern Wujin technology. The password lock is opened by collecting fingerprints of human fingers or inputting other decryption information as an unlocking password and taking the unlocking password as a trigger signal through a mechanical structure inside the lock body.

The coded lock is before not receiving accurate password information as the unblock password, and the handle of rotating the lock body can't be opened the lock body, and only after receiving accurate unblock password, the inside clutch of lock body just can link to each other triggering and the handle of spring bolt under the control of corresponding mechanism to can open the door. Because the execution of the internal mechanism of the coded lock is controlled by the electric signal, when the power supply of the coded lock is exhausted, the coded lock loses the basic function, and the door needs to be opened by a traditional mode, namely a key. Therefore, when the lock body fails, the lock body cannot be opened in any mode, and the structure is relatively complex, so that the manufacturing cost is high.

Disclosure of Invention

The utility model provides an above-mentioned problem, provide one kind and lose under the prerequisite that the electric energy provided, can be through the trick lock body that the key was opened the lock body.

The purpose of the utility model is realized like this:

the utility model provides a trick lock body, includes the casing to and connect the panel in casing one side, be equipped with the lockhole on the panel, be equipped with first rotary column on the casing, be connected with the spring bolt on the first rotary column, the spring bolt is including the first portion of rotating of cover on first rotary column to and extend the spring bolt main part and the first trigger end that form to both sides respectively, be equipped with the key hole on the casing, it is equipped with the second rotary column to lie in key hole one side on the casing, be connected with on the second rotary column and trigger the plectrum, trigger the plectrum including the second rotation portion of cover on the second rotary column, the second rotation portion outside extends and forms the second trigger end to and with first trigger end matched with execution end.

Furthermore, the trigger shifting piece is in an I shape, and the second rotating part is positioned at one corner of the I-shaped trigger shifting piece.

Furthermore, the shell is also provided with a limiting column, and the limiting column limits the upper end and the lower end of a notch on one side of the I-shaped trigger shifting piece.

Furthermore, a torsion spring is sleeved on the first rotating column, and the torsion spring enables the lock tongue to have a tendency of extending out of the lock hole.

Compared with the prior art, the utility model outstanding and profitable technological effect is:

this trick lock can drive through the rotation of key and trigger the plectrum under the circumstances that does not have the electricity, triggers the execution end of plectrum and contacts with the first trigger end of spring bolt, drives the spring bolt and receives inwards, realizes the purpose with the spring bolt closure. The structure is relatively simple, the used parts are few, and the lock body is independent from the clutch part of the lock body, so that the use is more reliable.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, a trick lock body, including casing 1 to and connect the panel 2 in casing 1 one side, be equipped with lockhole 3 on the panel 2, be equipped with first rotary column 4 on casing 1, be connected with spring bolt 5 on the first rotary column 4, spring bolt 5 is including the first rotation portion 51 of cover on first rotary column 4 to and extend the spring bolt main part 52 and the first trigger end 53 that form to both sides respectively, be equipped with key hole 9 on casing 1, it is equipped with second rotary column 6 to lie in key hole 9 one side on casing 1, is connected with on the second rotary column 6 and triggers pick 7, triggers pick 7 including the second rotation portion 71 of cover on second rotary column 6, and second rotation portion 71 outwards extends and forms second trigger end 73 to and trigger end 53 matched with execution end 72 with first trigger end. When the coded lock is not powered, that is, a corresponding electric signal cannot be given through a fingerprint, so that the clutch is connected with the handle to close the bolt, in the case of no power, in the structure of the coded lock, the key is inserted into the key hole 9 through the key, and the key further drives the lock cylinder, here, because the lock cylinder can be a component well known to those skilled in the art, which is not shown in fig. 1, the lock cylinder can drive the second trigger end 73 on the trigger plectrum 7, the trigger plectrum 7 can rotate counterclockwise around the second rotary column 6, in this process, the actuating end 72 on the trigger plectrum 7 is in contact with the first trigger end 53 of the bolt 5, and further drives the bolt 5 to rotate clockwise around the first rotary column 4, so that the purpose of retracting the bolt 5 into the inside of the lock body is achieved. The structure and the clutch part of the lock body are separated, so that the coded lock has relative independence, is simple in structure and low in manufacturing cost, and can ensure that the coded lock can still be unlocked by a key under the condition of no electricity.

Further, the trigger shifting piece 7 is in an i shape, and the second rotating portion 71 is located at one corner of the i-shaped trigger shifting piece 7. As can be seen from fig. 1, the trigger pulling piece 7 is in an "i" shape, and the second rotating portion 71 is located at the lower left corner of the "i" shape, so when the combination lock is kept in a vertical state, because the rotating point is located at the corner of the trigger pulling piece 7, the trigger pulling piece 7 moves clockwise due to self-gravity when being stressed, and after the lock body is opened by the key each time, the trigger pulling piece 7 resets under the self-gravity.

Furthermore, the shell 1 is also provided with a limiting column 10, and the limiting column 10 limits the upper end and the lower end of a notch on one side of the I-shaped trigger shifting piece 7. The limiting column 10 limits the rotation stroke of the trigger pulling piece 7, and avoids excessive rotation of the trigger pulling piece 7, so that the pressing force between the execution end 72 and the second trigger end 73 on the trigger pulling piece 7 is too large to cause damage.

Furthermore, a torsion spring 8 is sleeved on the first rotating column 4, and the torsion spring 8 enables the bolt 5 to have a tendency of extending out of the lock hole 3.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
