Description

Technical Field

[0001] The utility model belongs to the technical field of fly-proof screen windows, and in particular relates to a screen window lock buckle with convenient opening and closing. Background Art

[0002] With the acceleration of urbanization and population growth, the building density in cities is increasing. In order to improve the living environment and protect the health of family members, more and more families are installing screens. Screens can effectively prevent mosquitoes and other insects from entering the room, reducing the risk of family members getting sick. They can also effectively block external pollutants from entering the room, protecting the respiratory system and health of family members.

[0003] Existing screens are usually connected to the window frame in a fixed or sliding rail manner. Fixed screens are usually fixed to the window frame with screws, nails or other fixings. This connection method is usually used in high-rise buildings, which can block dust while also preventing it from falling. Sliding rail screens are usually provided with a slide rail on the edge or lower part of the window frame, and the edge of the screen will have a corresponding slide groove. Through the cooperation of the slide rail and the slide groove, the screen can be slid or fixed on the window frame. Sliding rail screens are the most common form of screens in life.

[0004] However, the above two common screens are not easy to disassemble and difficult to maintain. The screws of fixed screens will loosen and fall off after long-term use, which poses a certain safety hazard. Sliding screens will not slide smoothly due to dust or debris, and require regular maintenance or replacement of parts, which increases maintenance costs and difficulties. Both types of screens are also not easy to clean and will accumulate dust after long-term use. Utility Model Content

[0005] In view of this, the utility model provides a screen window lock buckle with convenient opening and closing, which can solve the problems of difficult disassembly and high maintenance cost of existing screen windows.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a conveniently opened and closed screen window lock buckle, which comprises a screen fan, a screen net and a screen fan pressure line, wherein the screen net is located between the screen fan and the screen net, the screen fan is located on the outside of the screen net, the screen fan pressure line is located on the inside of the screen net, the screen fan pressure line is fixedly connected to the screen fan lock, the screen fan is fixedly connected to the screen fan lock, the screen net and the screen fan are fixedly connected by bolts, a lock seat is arranged on the left side of the screen fan lock, the lock seat is fixedly connected to the card slot of the window frame, the screen net is used to prevent insects and small particles from entering the room, and the screen fan pressure line is used to prevent the screen net from being disassembled outdoors;

[0008] The screen fan lock has a first state of being inserted into the lock seat and a second state of being located outside the lock seat.

[0009] The technical effects of a conveniently-opened screen window lock provided by the utility model are as follows: the screen can effectively prevent mosquitoes, flies and other insects from entering the room, provide a comfortable living environment, and can block dust, fallen leaves and other debris from entering the room, keeping the room clean and tidy. The screen allows air to circulate freely, keeps the indoor air fresh, and prevents indoor overheating. The screen fan can be used to fix the screen to prevent children or pets from falling from the window, thereby improving indoor safety. The screen fan pressure line is set indoors to more firmly fix the screen, increase the stability of the screen, and prevent accidental falling or damage. The screen fan pressure line installed indoors is not easily damaged or pried open by outsiders, thereby improving the anti-theft performance of the window and enhancing the sense of home security. At the same time, there will be no protruding objects on the appearance, so that the outdoor structural lines are flat, smooth and smooth, thereby maintaining the overall aesthetics of the window and not affecting the appearance of the building. By setting a screen fan lock, it can be ensured that the screen remains fixed when closed, thereby preventing accidental opening. The screen fan lock is easy to operate, allowing the user to quickly lock or unlock as needed. The lock base can provide a more solid fixed support, making the screen fan lock more stable and reliable. It ensures that the screen fan lock is in the correct position and will not shift or loosen due to external force or vibration. It can effectively prevent the screen fan lock from slipping or moving during use, thereby increasing the anti-theft effect. The stable installation of the lock base can effectively prevent potential thieves or criminals from prying the screen fan lock, improving the anti-theft performance of the screen fan. It increases the difficulty for vandals to try to enter the room, providing additional protection for family safety.

The transmission rod is arranged in the slide groove. The transmission rod is slidably connected to the slide groove. A spring is fixed in the slide groove. The spring is fixedly connected to one end of the transmission rod. The spring is used to drive the transmission rod to reset. The other end of the transmission rod is fixedly connected to the locking point.

[0012] Furthermore, the lock seat includes a lock seat body, a fixed top screw and a barb, the fixed top screw is arranged inside the lock seat body, one end of the lock seat body is fixedly connected to the slot of the window frame through the fixed top screw, and the barb is fixedly connected to the other end of the lock seat body.

[0013] Furthermore, the barb is adapted to the locking point.

[0014] The beneficial effect of adopting the above-mentioned improvement scheme is that the barb is compatible with the locking point, which can ensure that the locking point and the barb are locked tightly, preventing criminals from entering the room by prying or destroying the locking point, thereby improving the safety of the home.

[0015] Furthermore, a yarn fan pressing line rubber strip is provided on the yarn fan pressing line, the yarn fan pressing line rubber strip is fixedly connected to the yarn fan pressing line, and the yarn fan pressing line rubber strip is fixedly connected to the yarn net.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the pressure strip of the screen fan can form a seal between the screen window and the window frame when it is in the first state, which can effectively prevent rainwater from entering the room and improve the watertight performance of the screen window; the pressure strip can reduce the exchange of heat between indoor and outdoor, play a certain thermal insulation effect, and reduce the energy consumption of air conditioning or heating.

[0017] Furthermore, the locking point is a mushroom head type structure.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the mushroom head type locking point usually has a larger locking head area and a more secure locking design, which can provide a more reliable locking effect, increase the safety of the screen window, and effectively prevent intrusion and accidental opening.

[0019] Furthermore, the diameter of the locking point is larger than the diameter of the transmission rod, and the diameter of the locking point is smaller than the diameter of the sliding groove.

[0020] Furthermore, the gauze is made of glass fiber.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the glass fiber mesh is made of high-strength glass fiber, has good weather resistance and corrosion resistance, is not easily corroded by sunlight, rain and chemicals, and has a long service life. It has excellent light transmittance, can keep the room bright, and effectively block the damage of ultraviolet rays, protecting furniture and floors from sunlight damage. It has good tensile resistance, is not easy to deform or break, can withstand wind and rain and external force impact, and maintain a stable shape.

[0022] Furthermore, the number of the barb is one, and the barb is located on the inner side of the gauze.

[0023] Furthermore, the overall length of the transmission rod and the locking point is 10 cm.
