Description

Technical Field

[0001] This utility model relates to a top-windowed insect-proof net anti-detachment device. Background Technology

[0002] In modern agriculture, agricultural greenhouses, as environmental control facilities, often require skylights to regulate temperature and humidity. To prevent insects from entering, insect netting is typically installed on the skylights. However, in strong winds, this netting is easily blown away or detaches from the frame, reducing its effectiveness against insects. Current insect netting fixing devices typically rely on clips or clamps, but in windy conditions, existing technology has not effectively solved the problem of netting detachment. Especially in large, well-ventilated environments like agricultural greenhouses, securing the insect netting securely is a pressing technical issue that needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to provide a device to prevent insect nets from falling off when the skylight is opened at the top, so as to ensure that the insect nets remain firmly inside the skylight frame under the action of wind, thereby preventing the insect nets from falling off.

[0004] To achieve the above objectives, the present invention adopts the following design scheme:

[0005] A device for preventing the insect net from falling off a top-opening window is characterized by comprising: an insect net, insect net hooks, and an insect net slide rail. The upper end of the insect net is fixed to the window sash frame, and the lower end of the insect net is fixed to the lower window frame. Several insect net hooks are hung on the insect net, and the insect net hooks are movably fitted onto the insect net slide rail. The insect net slide rail is located inside the insect net. The upper end of the insect net slide rail is installed on a window sash connector, which is connected to the window sash frame. The lower part of the insect net slide rail slides through the lower window frame connector.

[0006] The insect-proof net hook is made by bending steel wire into a U-shape. The two steel wire arms are bent towards each other to form a steel ring. The steel ring is fitted onto the insect-proof net rail. The arms on both sides of the steel ring are bent vertically away from the steel ring. Their free sections pass through the insect-proof net and then fold back through the insect-proof net before extending under the arms on both sides of the steel ring.

[0007] The insect-proof net sliding rail includes an arc-shaped rail and a reinforcing section. The upper end of the arc-shaped rail is bent through the horizontal axis tube of the window sash connector and bent downwards. The lower end of the arc-shaped rail is bent upwards to form a reinforcing section. The upper end of the reinforcing section is connected to the upper end of the arc-shaped rail.

[0008] The window sash connector includes a support and a horizontal axis tube. The support is mounted on the side of the window sash frame opposite to the hinge axis of the window sash and the lower window frame by screws.

[0009] The lower window frame connecting piece comprises a steel wire fixing piece and a double-way pipe, the steel wire fixing piece is formed by bending a steel wire, and comprises a clamping part and a penetrating part, the clamping part is clamped in the lower window frame, and branches extended on both sides of the clamping part penetrate out of both sides of a horizontal pipe of the double-way pipe respectively, and the arc-shaped rail penetrates through a vertical pipe of the double-way pipe.

[0010] The utility model discloses the advantages are: the utility model discloses simple installation, and user only needs to fix the insect screen slide rail through the window sash connecting piece on the skylight window sash, and then the arc-shaped rail other end is penetrated in the vertical pipe through the lower window frame connecting piece.
