Description

Magnetic spring type door and window handle stopper for preventing children from opening accidentally

Technical Field

The utility model relates to a magnetic spring door and window handle dog for preventing children's accident from opening in the housing construction design technical field.

Background

The window in the technical field of building design is a basic construction element of a building and is a carrier for lighting, ventilation, burglary prevention, landscape observation and building attractive appearance. However, windows, especially bay windows (also known as bay windows) widely used in buildings, are often a household safety hazard that endangers children's safety. Under the development situation that the demands of high-grade doors and windows of residents are higher and higher, more and more casement doors and windows are used for building doors and windows at present. When the window is locked, the handle is in a horizontal state, and when the window is opened, the window handle rotates by 90 degrees, so that the flat-open function of the window can be realized. The disadvantage of this method is that no matter adults or children can open the window at will to achieve the flat-open function. Therefore, the hidden danger of falling after the child opens the window by oneself can be caused.

The news reports that the event that children fall from the building happens occasionally, the training is very painful, so that many families choose to install the anti-theft net, the children can be prevented from being stolen and the falling event of the children can be avoided, but the anti-theft net not only influences the appearance of the building, but more importantly has great fire-fighting and escape potential safety hazards, and once a fire disaster happens, the anti-theft net is a great obstacle for escaping. Also have the window handle of taking the key in the market, can lock the handle with the key after the window is closed, take off the key, prevent that the window is unexpected to be opened, reinsert the key when needing to open the window, open the handle lock. However, the handle with the key needs to be frequently inserted and pulled out, the key is troublesome to manage, and once the key is lost, the window lockset can be integrally replaced. In order to prevent children from opening the window accidentally, ensure the safety of the children and completely eliminate the falling risk of the children, a plurality of parents consider installing a safety lock for the window at home, so that the children are prevented from turning the handle of the window curiously and the normal opening and closing of the window at ordinary times are not influenced. Although those skilled in the art have devised child-resistant lock devices that prevent accidental opening of windows, they are not ideal.

Patent application number CN209384782U discloses a child door lock catch, which comprises a base, a first lock handle and a second lock handle, wherein the first lock handle and the second lock handle are respectively rotatably arranged on the base; the base comprises a base, a protruding frame integrated with the base and tubular installation parts respectively arranged at two ends of the protruding frame, wherein the outer wall of each installation part is provided with a limiting groove and a plurality of clamping grooves; also can accomplish the function that prevents children from rotating the window handle in the patent application, but adopted the structure of two lock handles in the design, and the unable regulation of distance between first lock handle and the second lock handle. The application of the patent has three problems that firstly, the handles of most windows are of a horizontal and vertical two-position structure, namely the rotation range of the handles is 90 degrees, the handles are in a horizontal state when the windows are closed, the handles can be locked only by one lock handle, and the two lock handles are certainly wasted; secondly, the lock handle of the patent adopts a rotating mode, the gap between the lock handle and the handle cannot be minimized, and particularly for the handle with an irregular shape, the gap between the lock handle and the handle is possibly too large, so that the risk of window locking failure is caused; thirdly, the locking handle locking mechanism of the patent can be unlocked by one hand, and children may unlock the lock if repeatedly trying, so that the locking handle is rotated, and the risk of window locking failure exists. The prior art also has the problems, and the requirements of users on safety locks with safety, reliability and usability cannot be met. Therefore, it is an urgent need to develop a detent device for a door knob of a magnetic spring type for preventing children from being accidentally opened.
