Abstract

The invention relates to a door or window stop lock device. A combination lock device is assembled between a lock shell and a bottom cover, and a lock rod is arranged in a penetrating manner; the combination lock device comprises a plurality of digit wheel sets, a wheel shaft, a spring and the like, so that the lock rod can be limited or released, and can stretch outwards or retract inwards; by the structural operation, the door or window stop lock device can be mounted on a door or window track of an exterior wall of a high-rise building to stop the opening amplitude of a door or a window from being over large, the safety is guaranteed, the door or window stop lock device can be operated and used without an additional key, inconvenience and trouble which are caused by losing of the key are avoided when the door or window stop lock device is used, use burden of consumers on carrying of keys is reduced, therefore, market acceptance is improved relatively, meaningless expenditure on manufacturing of new keys of the consumers is further avoided, and the door or window stop lock device has multiple progresses of economic benefit when used.

Description

technical field [0001] The invention relates to the technical field of a door and window lock device, in particular to an innovative structure of a door and window lock device with a variable combination lock function. Background technique [0002] Generally, aluminum doors and windows consist of an outer frame and at least two door bodies. The outer frame has a bottom frame with parallel double rails to support each door body, and forms a door and window structure that supports the door body to slide for switch operation: and in use For occasions that have safety concerns about door opening, such as high-rise exterior wall doors and windows, it is necessary to limit the opening range of the door body. At present, most of the industry generally provides a device in the middle of the stroke of the sliding opening and closing of the door on the bottom frame of the aluminum door and window. A door stopper that can block the sliding door body to prevent the danger caused by the ...

Problems solved by technology

[0004] However, the lock body whose opening and closing is controlled by a key must be carried with you in use, and it is easy to forget or lose it so that the opening and closing control cannot be performed, causing inconvenience and trouble in use, which is one of the shortcomings of the existing door stopper structure. one

[0005] Furthermore, because in a modern society with developed industry and commerce, all vehicles such as automobiles and motorcycles, or the doors of homes, offices and other places need keys to control and switch, everyone has a lot of keys to carry in their existing lives. The structure controlled by the key will increase the carrying burden of consumers and reduce the acceptance of consumers, which is the second shortcoming of the existing door stopper structure.

[0006] Finally, if the key control structure is used, once the key is lost, the consumer will have to spend money to get a new key, which will further increase the unnecessary cost of the consumer, which is not in line with economic benefits, and is the third shortcoming of the existing door stopper structure.

[0007] Therefore, how to address the inconvenience and troubles of using the above-mentioned existing door stopper structure that cannot be used for opening and closing control due to forgetting and losing, and increase the burden on consumers to use and reduce the acceptance of consumers in use, and further increase consumers. Unnecessary expenses, disadvantages such as inconsistency with economic benefits and inventions are the difficulties to be solved by the present invention
