Description

Door and window lock device (2)

The invention relates to the technical field of door and window lock devices, in particular to an innovative structure of a door and window lock device with a variable number lock function.

Generally, aluminum doors and windows generally comprise an outer frame and at least two door bodies, and the outer frame has a bottom frame and parallel double rails for supporting the door bodies, and the door and window structure for supporting the door body to slide and switch operation is: In the use of the door for safety concerns (such as high-rise exterior doors and windows), it is necessary to limit the opening of the door. At present, most of the industry is on the middle of the aluminum door and window frame at the middle of the stroke that provides the door panel sliding and opening and closing. There is also a door stopper that can block the sliding door body to prevent the danger caused by the opening and closing of the door and window.

As shown in the ninth figure, a perspective view of a conventional door damper includes a lock body (6) that uses a key (61) to control a lock rod (62) that is vertically threaded. Restricting the lock lever (62) when the key (61) is closed, and releasing the lock lever (62) when the key (61) is opened, so that the lock lever (62) is actively extended to block the open door body. In order to prevent the door and window from opening too large.

However, the lock body that is opened and closed by the key must be carried with it in use, and it is easy to forget and lose the control due to forgetting or losing, which causes inconvenience and trouble in use, and is a disadvantage for the use of the structure of the damper device. One.

Moreover, due to the modern society where the industry and commerce are developed, the gateways of vehicles, motorcycles, etc., or homes, offices, etc. all need keys to be able to control and switch. Everyone has to carry a lot of keys in their existing lives. The structure of the key control is the second disadvantage of the structure of the damper device because it increases the carrying burden on the consumer and reduces the acceptance of the consumer.

Finally, using the structure of the key control, once the key is lost, the consumer has to spend money to create a new key, which further increases the unnecessary cost of the consumer, which is not economical, and is the third disadvantage of the structure of the damper.

Therefore, how to deal with the above-mentioned structure of the door damper structure is easy to forget and lose the inconvenience and trouble of opening and closing control, increase the burden on consumers to use, reduce consumer acceptance, and further increase consumers. It is a difficult point for the invention to solve the problem by making unnecessary expenses and not inferior to economic benefits.
