Description

Technical Field

[0001] The utility model relates to the technical field of mechanical locks, in particular to a high-security mechanical lock. Background Art

[0002] As the name implies, a door lock is a device used to lock a door to prevent others from opening it. There are many types of door locks, and the requirements for door locks vary in different occasions. Ordinary families generally use anti-theft door locks, which are highly secure and relatively inexpensive.

[0003] The utility model patent with authorization announcement number CN217975794U discloses a mechanical lock, which includes a lock sleeve and a locking block. The lock sleeve is provided with a lock core, a controller is provided at the left end of the lock core, an electromagnet is provided on the left side of the lock core, a sliding block is provided in the middle of the right end of the lock core, an electromagnetic guide block is slidably mounted in the middle of the sliding block, a lock tongue is provided at the right end of the electromagnetic guide block, and a limit block is provided inside the locking block. The utility model controls the electromagnet to generate a magnetic field by the controller. The magnetic field force of the electromagnet is greater than the elastic force of the spring. The electromagnet drives the electromagnetic guide block to move the lock tongue to the left, breaking away from the limit of the lock tongue on the lock tongue, thereby achieving the door lock opening. When the door needs to be closed, the controller controls the power supply of the electromagnet according to the instruction delay. When the electromagnet is de-energized, the magnetic field force disappears, and the elastic force generated by the spring to the right side inserts the lock tongue into the limit block through the connection of the crossbar, achieving automatic locking. In the normal locked state, the lock is controlled by elastic force, which is more stable.

[0004] Although the above utility model can quickly and conveniently open the lock by controlling whether the electromagnet is energized, if a fire causes a power outage and the electromagnet cannot be powered, the door lock cannot be opened quickly and conveniently, which is very unsafe. In view of this, we propose a high-security mechanical lock. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5 , this embodiment provides a technical solution:

[0027] A high-security mechanical lock includes a shell 1. A connecting groove 11 is opened in the middle position of the right surface of the shell 1. A locking bolt mechanism 12 is arranged in the connecting groove 11. A mounting groove 13 is opened on the left surface of the connecting groove 11. A rotating mechanism 14 is arranged in the mounting groove 13. A sliding groove 15 is opened on the left surface of the connecting groove 11. A sliding hole 17 is opened on the left surface of the sliding groove 15. A spring groove 16 is opened at the right end of the outer surface of the sliding hole 17. An auxiliary mechanism 18 is slidably connected to the sliding hole 17. Through the above mechanism, the door lock can be conveniently controlled, and the door lock can be controlled conveniently, quickly and safely.

[0028] It should be added that the magnetic force of the magnet 181 is greater than the elastic force of the connecting spring in the latch mechanism 12 .

[0029] Furthermore, the rotating mechanism 14 includes a rotating block 142, a lock core 141 installed on the rear surface of the rotating block 142, and a rotating rod 143 installed on the front surface of the rotating block 142. A rotating disk 144 is welded to the front end of the rotating rod 143, and a handle 145 is welded to the front surface of the rotating disk 144. The rotation of the rotating disk 144 is controlled by rotating the handle 145.

[0030] Furthermore, the auxiliary mechanism 18 includes a magnet 181 , a sliding rod 183 fixedly mounted on the left side surface of the magnet 181 , and a spring 182 fixedly mounted on the left side surface of the magnet 181 , and the spring 182 enables the magnet 181 to slide along the sliding hole 17 .

[0031] In this embodiment, when no external force is applied, the connecting spring in the locking mechanism 12 is in a stretched state, and the connecting spring in the locking mechanism 12 pulls the entire locking mechanism 12 to the left.

[0032] In this embodiment, the right sides of the upper and lower surfaces of the sliding groove 15 are both beveled, and the depth of the spring groove 16 is equal to half the depth of the sliding hole 17, so that the spring 182 can enter the spring groove 16 as a whole.

[0033] In this embodiment, the rotating block 142 is elliptical in shape as a whole. The four ends of the rotating block 142 are flattened, and the side surface of the rotating block 142 is smooth, which reduces the friction generated by the rotating block 142 with the outside world when rotating.

[0034] In this embodiment, the rotating block 142 is made of a magnetic material, and the latch mechanism 12 is also made of a magnetic material. The rotating block 142 can transmit the magnetic force of the magnet 181 to magnetically fix the latch mechanism 12 .

[0035] In this embodiment, the other end of the spring 182 is welded to the inner bottom surface of the spring groove 16, and the left and right surfaces of the handle 145 are provided with anti-slip grooves to increase the friction generated by the user's contact.

[0036] Among them, it is worth mentioning that the structure and working principle of the lock core 141 involved in this embodiment are as well known to those skilled in the art, and will not be elaborated here. The structure and working principle of the locking bolt mechanism 12 involved in this embodiment are as well known to those skilled in the art, and will not be elaborated here.

[0037] During the specific use of the high-security mechanical lock of this embodiment, when it is necessary to lock the door, the user is inside and just controls the handle 145 to rotate the rotating disk 144 90 degrees. Under the action of the rotating rod 143, the rotating block 142 also rotates 90 degrees. After the rotating block 142 rotates 90 degrees, it is in a horizontal state. At this time, the horizontal length of the elliptical rotating block 142 is greater than the vertical length, which squeezes and drags the locking bolt mechanism 12 on the right side of the rotating block 142 outward to complete the locking action. When the user is outside, he inserts the key into the lock cylinder and then controls the rotating block 142 to rotate. Other actions are the same as above.

[0038] When the door lock needs to be opened, the user holds the handle 145 again to control the rotating block 142 to rotate 90° to a vertical state. At this time, the magnet 181 moves to the right under the push of the spring 182 until it contacts the rotating block 142, and the locking bolt mechanism 12 also moves to the left under the action of the internal connecting spring. The magnet 181 transmits magnetic force through the rotating block 142 to adsorb and fix the locking bolt mechanism 12 moving to the left, completing the unlocking action.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
