Description

Technical Field

[0001] The utility model relates to the technical field of screen windows, in particular to an anti-theft outward-opening diamond mesh anti-theft screen window. Background Art

[0002] Exterior-hung screen windows are a common window design, characterized by their ability to open outward. This design not only optimizes ventilation within the living space but also effectively increases the amount of natural light entering the room. Furthermore, compared to inward-opening windows, exterior-hung screen windows do not occupy interior space when open, making them more suitable for smaller and more compact homes.

[0003] While exterior-hinged screens are popular for their excellent ventilation and space-optimizing properties, existing designs have significant vulnerabilities when it comes to theft prevention. First, many traditional screens utilize mesh made of fiber materials or low-strength metals, which are extremely fragile and easily damaged by sharp tools or shears. Once the mesh is torn, criminals can easily penetrate the screen, providing unauthorized access to the home and posing a significant threat to the property and personal safety of residents.

[0004] Furthermore, existing screens often utilize a single-point internal locking mechanism. This design is not only susceptible to failure when subjected to external force or prying, but also offers virtually no tamper-proof protection once the screen is damaged. This simple locking mechanism often makes windows an easy target for intruders, leaving residents feeling less confident in their home security. This is why we offer pry-resistant, externally hinged, diamond mesh security screens. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-theft outward-opening diamond mesh anti-theft screen window to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The pry-proof outer casement diamond mesh anti-theft screen window includes a mounting frame, which is a part of the window frame or is directly fixed to the wall, providing structural support for the entire screen window system to ensure the stability of the screen window. A frame-shaped anti-pry groove is provided at the inner edge of the rear side of the mounting frame. The screen window is hinged inside the mounting frame. The hinge is a commonly used internal hidden hinge for window installation. It is a prior art and will not be described in detail here. The screen window includes a window frame, and a diamond mesh and a protective layer are provided inside the window frame. The diamond mesh is located directly behind the protective layer. The diamond mesh is woven from high-strength stainless steel wire. The surface is treated with electrophoretic spraying, which plays a major role in preventing external intrusion and also serves as a breathable function. The protective layer provides additional mechanical strength and anti-intrusion protection. A frame-shaped anti-pry plate is provided on the rear side of the outer wall of the window frame. The frame-shaped anti-pry plate is located in a frame-shaped anti-pry groove. When the screen window is closed, the frame-shaped anti-pry plate and the installation frame form an integral whole. When criminals want to pry open the screen window, they will first pry open the frame-shaped anti-pry plate. Even if the frame-shaped anti-pry plate is pried open, the connection between the window frame and the installation frame will be blocked by the frame-shaped anti-pry plate, greatly increasing the difficulty of prying open, thereby playing a role in preventing prying open;

[0008] A rectangular positioning block is provided on the front side of the window frame, near the upper and lower ends of the right side, and a socket is provided on the top of the rectangular positioning block. A double lock piece that can move up and down is provided on the front side of the mounting frame, near the right side, and the double lock piece includes two horizontal strips that are symmetrically arranged up and down, and a connecting vertical rod is provided between the two horizontal strips. A locking rod is provided at the bottom of the two horizontal strips, near the left end, and the two locking rods are respectively inserted into the two sockets, and the two horizontal strips are driven up and down by the connecting vertical rod, so that the two horizontal strips drive the two locking rods to move synchronously. When the two locking rods are respectively inserted into the two sockets, the positions of the two rectangular positioning blocks are fixed, which can prevent the screen window from being opened. At the same time, two locking points are provided to enhance the stability of the screen window after closing.

[0009] Preferably, a first transverse plate is provided on the front side of the mounting frame and near the lower middle portion of the right side, and the top end of the connecting vertical rod passes through the bottom of the first transverse plate to connect the double locking member to the mounting frame.

[0010] Preferably, a second horizontal plate is provided on the front side of the mounting frame and near the top right side, magnets are embedded in the bottoms of the first horizontal plate and the second horizontal plate, and iron sheets are embedded in the tops of the two horizontal strips. When the screen window needs to be opened, the user moves the connecting vertical rod upward, and the connecting vertical rod drives the two horizontal strips to move upward, so that the two horizontal strips respectively drive the two locking rods to move upward synchronously until the two iron sheets are respectively adsorbed and connected with the two magnets, so that the positions of the two horizontal strips are fixed. At this time, the two locking rods are completely removed from the two insertion holes, thereby releasing the lock of the two rectangular positioning blocks, and allowing the screen window to be smoothly opened outward.

[0011] Preferably, a rectangular push block is provided in the middle of the outer wall of the connecting vertical rod, and the rear side of the rectangular push block is in contact with the front side of the mounting frame, so as to facilitate the user to move the double lock piece up and down and ensure that the double lock piece will not rotate during movement.

[0012] Preferably, a fixed handle is provided on the front side of the window frame near the middle of the right edge to facilitate users to move the screen window.

[0013] Preferably, a first limit frame is provided on the rear side of the inner wall of the window frame, and a second limit frame is provided on the inner wall of the window frame and close to the front side of the first limit frame. The diamond mesh is located between the first limit frame and the second limit frame, and the first limit frame and the second limit frame press and fix the diamond mesh.

[0014] Preferably, a third limiting frame is provided on the front side of the inner wall of the window frame, and the protective layer is located between the second limiting frame and the third limiting frame, and the second limiting frame and the third limiting frame press and fix the protective layer.

[0015] Preferably, the protective layer includes a plurality of metal horizontal bars arranged equidistantly up and down, and the distance between two adjacent metal horizontal bars is 40-50 mm. The protective layer also includes a plurality of metal vertical bars arranged equidistantly left and right, and the distance between two adjacent metal vertical bars is 40-50 mm. The metal vertical bars pass through the outer walls of the plurality of metal horizontal bars in sequence to improve the overall strength and prevent the hands of criminals from passing through.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The pry-proof, outward-opening diamond mesh security screen uses high-strength stainless steel diamond mesh and a reinforced protective layer, which not only effectively prevents the screen from being cut, but also increases the overall difficulty of prying. The rear side of the window frame and the installation frame are coordinated through the frame-shaped anti-pry plate and the frame-shaped anti-pry groove, so that even if criminals try to pry open the screen, it will still be difficult to pry open due to the structural obstruction of the frame-shaped anti-pry plate and the frame-shaped anti-pry groove. This design cleverly increases the difficulty of forced opening from the outside and improves home safety.

[0018] 2. The pry-proof outward-opening diamond mesh security screen has a double-locking design through horizontal strips, connecting vertical rods and locking rods, providing double locking functions. It can lock the screen at the upper and lower positions, avoiding the disadvantage of single-point locks that are easily invalidated under external forces, and effectively preventing unauthorized opening.

[0019] 3. The anti-theft outer casement diamond mesh security screen has evenly distributed metal horizontal bars and metal vertical bars, which make the protective layer strong enough to prevent hand penetration, and provide additional structural strength without affecting ventilation and light transmission.
