Multi-directional door and window limiting and fixing device

Abstract

The invention discloses a multi-directional door and window limiting and fixing device. According to the scheme, a lock cylinder fastener is arranged at one end of a connecting pull rod, wherein the lock cylinder fastener can make the connecting pull rod rotate in multiple directions with a lock body base as the axis, and the lock cylinder fastener is arranged at the other end of the connecting pull rod in a matched mode, wherein the lock cylinder fastener can rotate in multiple directions with the end of the connecting pull rod as the axis. The effects that the opening degree of a door and a window can be limited and fixed when the multi-directional door and window limiting and fixing device is installed at any position and any angle can be achieved. Meanwhile, the lock cylinder fastener rotating in multiple directions is matched with a locking base with multiple locking positions, and even if the installation angle is inclined, positioning connection can still be achieved. Compared with a traditional commercially available door and window safety lock, the multi-directional door and window limiting and fixing device is more flexible; meanwhile, the requirement for the installation space due to the multi-directional installation characteristic is lower than the requirement for the space due to a traditional door and window limiting device, and the multi-directional door and window limiting and fixing device can be conveniently and flexibly applied to various places needing to be opened and closed. The locking base is matched with an unlocking piece simple in structure, the lock cylinder fastener can be reliably locked in the locking positions, and the multi-directional door and window limiting and fixing device is convenient and rapid to use and operate.

Description

technical field [0001] The invention relates to the field of safety locks, in particular to a multi-directional door and window limit fixing device. Background technique [0002] Door and window safety lock, also known as door and window limit lock or door and window limit device, is a brand-new protective anti-theft window lock that has gradually become popular. It is a new type of building security product installed on doors and windows to provide protection, anti-theft, anti-falling objects and other safety guarantees for home life and office. There was no concept of children's door and window safety locks before, but with more and more high-rise residential buildings Incidents of children and pets falling from buildings have become news headlines from time to time. Major hotels immediately set up rough safety locks, that is, nails are used to nail the metal position on the edge of the window to prevent passengers from pushing the window open; in the early days Some fami...

Problems solved by technology

[0003] However, the existing door and window safety locks can only open and close doors and windows along the fixed track designed by them. After the user purchases them, the installation angle will inevitably be skewed during installation. High, once pasted, it is not easy to adjust the position. At this time, if the installation angle is wrong, the door and window safety lock will not move along the preset track, which may cause the doors and windows to fail to open or close smoothly, and seriously The door and window safety locks are completely unable to work and cause damage, lose their own meaning of existence, and cause a lot of unnecessary troubles to users

[0004] In addition, due to the problem of the fixed trajectory movement of the existing door and window safety locks, there will be many restrictions on the space of the installation environment and the installation direction. If the space in the installation location is not enough, the installation will fail or be unstable, and it cannot be used flexibly. For furniture with different switching methods such as sliding windows and sliding windows, the safety locks used cannot be used universally due to the limited movement mode due to their own structure, and in furniture such as sliding windows or sliding doors that perform relative displacement actions on the same trajectory , because the gap between two relatively displaced doors or windows should not be too wide, otherwise the proper existence of doors and windows will be lost, and the existing door and window safety locks will easily It is very troublesome if there is a situation that hinders the opening and closing of doors and windows
