The opening protection device has the beneficial effects that the opening protection device has the advantages of simple overall structure, simple manufacturing process, low cost and high universality; 2, a non-contact structure is adopted, so that freeness from wear and noise and low wear rate are achieved; 3, actions are flexible, and small-distance displacement can be realized by using the pressure of a car door driving stop lever on the driving wheel of a driving swinging arm in order to open a coupler lock swinging arm at a large angle, so that operation is convenient and easy; 4, high safety performance is achieved, the probability of accidental fall of operating personnel into a hoist way is lowered, and the personal safety of operators is guaranteed.

The present invention relates to an article of clothing that is worn by a person for preventing an infant from accidental falling while the person nurses the infant. The article may be a garment that includes an item of clothing to be worn by a person and a support garment panel attached to the item of clothing. The support garment panel is attached to the perimeter of the armholes of the item of clothing and defines a pocket between the support garment panel and the item of clothing. The pocket includes an opening for receiving an infant and a base for supporting the infant.

The invention provides a frame window capable of preventing objects from falling from a window opening unexpectedly and avoiding harmful mosquitoes or covering as well as protecting and preventing burglary. According to needs, the length of a metal section containing a hole and the magnetism is selected and intercepted, metal sections form a frame through section connecting pieces, an assembly mechanism is arranged on the frame body, a thin steel wire rope passes through holes on opposite sides of the frame body to and fro to form a protective screen, steel wire fastening bolts are fastened on the holes; another kind of magnetic strips form a magnetic strip frame with the same size as the section frame magnetic part, a gauze is stuck to the flexible magnetic strip frame to form a gauze with the magnetic frame; the magnetic frame gauze and the frame magnetic part are absorbed together; and the frame body is arranged on on the window opening through a fixed piece. The frame window has a simple structure, simple and beautiful appearance and low cost, does not hinder people viewing indoors, and does not influence the whole sight of a house.
