[0002] In modern society, latches are often used to lock doors. Ordinary latches can be opened or closed only by using a key or even manually. They only have the function of closing the door and cannot prevent theft. The function of locking the door cannot be realized after damage, so it is necessary to design a linear latch device that can close the door and has double insurance, and can manually lock the door when the interior is damaged. This device can not only prevent people from leaving the key Legacy things happen, and there is double insurance to prevent others from only needing to use the key to open it, and it can also manually lock the door if there is damage inside the unit

The latch is easy to operate, and convenient to use, the conditionthat a person leaves a key after leaving is avoided, the insurance is achieved, and a door can be manually locked after the latch is damaged.
Description
technical field [0001] The invention relates to the field of security and anti-theft, in particular to a linear extrusion latch. Background technique [0002] In modern society, latches are often used to lock doors. Ordinary latches can be opened or closed only by using a key or even manually. They only have the function of closing the door and cannot prevent theft. The function of locking the door cannot be realized after damage, so it is necessary to design a linear latch device that can close the door and has double insurance, and can manually lock the door when the interior is damaged. This device can not only prevent people from leaving the key Legacy things happen, and there's double insurance against someone else just using a key to open it, and the ability to manually lock the door if there's damage to the inside of the unit. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a linear extrusion latch, which...
