Description

Multi-directional door and window limiting and fixing device

Technical Field

The invention relates to the field of safety locks, in particular to a multi-directional door and window limiting and fixing device.

Background

The door and window safety lock, also called door and window limit lock or door and window limit device, is a brand new protection anti-theft window lock which is popular gradually. The novel building security product is arranged on doors and windows and provides security safeguards for home life and offices, such as protection, prevention, falling prevention and the like, has no concept of child door and window security locks, but has the advantages that as high-rise houses are increased, infants and pets fall down to the building, the infants and pets become news headlines, and rough security locks are arranged at the first time in each hotel, namely, the metal positions at the edges of the windows are nailed by iron nails, so that passengers are prevented from pushing the windows open the windows greatly; the early family decoration part is used for the guard rail, but the decoration cost of the method is higher, and all places where windows are impossible are in accordance with the guard rail, so the potential safety hazard still exists, the first generation of child safety locks are marketed when the locks are made of metal and are embedded into the metal window edges through screws, and the locks are not attractive in general and are only relatively elegant compared with the earliest iron nails. The second generation child sliding window safety lock is manufactured by adopting a high-strength ABS+TPU material, has the advantages of super shock resistance and shock absorption, is nontoxic and environment-friendly, does not contain toxic substances of formaldehyde, is fixed on a door or a window which generates relative displacement and corresponds to the door or the window respectively in a double-sided gluing mode, and can safely protect babies, old people and pets without damaging the door or the window, so that the sliding window is prevented from falling down accidentally, and can be detached at any time without damaging the door or the window.

However, the existing door and window safety lock can only open and close the door and window along the designed fixed track, after the user purchases by himself, the situation that the installation angle is askew can not occur in the installation process, but the requirement of the door and window safety lock on the viscosity characteristic of the double faced adhesive tape is higher, once the door and window safety lock is stuck, the door and window safety lock is not easy to adjust the position, at the moment, if the installation angle is wrong, the door and window safety lock can not move along the preset track, the door and window can not be opened or closed smoothly, the serious door and window safety lock can not work completely to generate damage, the meaning existing in the door and window safety lock is lost, and a lot of unnecessary troubles are caused for the user.

In addition, the existing door and window safety lock has a plurality of limitations on the space and the installation direction of an installation environment due to the problem of moving of the existing door and window safety lock along a fixed track, if the space of an installation position is insufficient, the installation is failed or unstable, the existing door and window safety lock cannot be flexibly applied, and furniture with different opening and closing modes such as a sliding window and a moving window cannot be commonly used due to the fact that the moving mode is limited due to the structure of the existing door and window safety lock, and furniture with relative displacement actions on the same track line such as the moving window or the moving door cannot be too wide due to the fact that a gap is required between two relatively displaced doors or windows, otherwise the due existing door and window safety lock loses the effect of the existing door and window, and the existing door and window safety lock is very troublesome due to the fact that the thickness of the existing door and window safety lock cannot be reduced due to the structure of the existing door and window safety lock.

Therefore, the existing door and window limiting device needs to be further improved.
