[0002] Security bars refer to a layer of mesh doors and windows with anti-theft protection added to the original windows of a building. Screens refer to nets that block mosquitoes and flies. The main function of screens is to "keep out mosquitoes." However, most security bars and screens on the market currently function independently, lacking a door and window security system that can both prevent insects and theft.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0005] A folding insect-proof and burglarproof door and window railing includes: a screen frame that is externally or internally hung on a window frame; the screen frame is a rectangular frame formed by connecting two screens at the top and bottom, two screen brackets, four corner brackets of the same size, and four angle steel plates of the same size by pins; a screen lock seat is threadedly connected to either side of the screen brackets; a lock hole is punched on the side of the screen lock seat; a screen railing panel is slidably installed between the two screens at the top and bottom; a lock body is installed on the side of the screen railing panel near the screen lock seat, while the side away from the screen lock seat is threadedly connected to the adjacent screen bracket by screws.

[0006] The screen window guardrail consists of a single-groove guardrail, a double-groove guardrail, a screen window guardrail, and pulleys. There is a single-groove guardrail on each of the left and right sides of the screen window guardrail, and multiple double-groove guardrails are set between the two single-groove guardrails. The single-groove guardrails and double-groove guardrails, as well as between two adjacent double-groove guardrails, are all threaded with screen mesh.

[0007] The lock body is installed on a single-line groove railing near the screen window lock seat.

[0008] The mesh is a foldable flexible diamond mesh made of 304 stainless steel, and the spacing between the single-groove railing and the double-groove railing, as well as the spacing between the double-groove railings, is less than 50cm.

[0009] Screen window pressure strips are provided between the single-pressure groove railing and the screen window pressure line, as well as between the double-pressure groove railing and the screen window pressure line.

[0010] The single-line groove railing is also equipped with anti-collision blocks.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 5 As shown,

[0024] A folding insect-proof and burglarproof door and window railing includes: a screen frame 1 that is externally or internally hung on a window frame 2; the screen frame 1, whether externally or internally hung on the window frame 2, is connected to the window frame 2 by threads. The externally hung screen frame 1 is used on a single inward-opening window, and the internally hung screen frame 1 is used on a single outward-opening window. The screen frame 1 is a rectangular frame formed by connecting two screen top and bottom brackets 101, two screen light brackets 102, four corner brackets 6 of the same size, and four angle steel plates 8 of the same size via pins. The screen top and bottom brackets 101 and the screen light brackets 102 have the same external dimensions. The main difference is that the internal groove of the screen top and bottom brackets 101 has a circular track protrusion 105. The main steps of the pin-connected angle connection are: first, connect the two screen top and bottom brackets... The ends of square 101 and the two screen light brackets 102 are cut at 45 degrees, and a pin hole 703 is made on each end of the back of the top and bottom 101 and the screen light bracket 102. The corner bracket 6 and the steel plate 8 are respectively placed into the corner bracket cavity 103 and the steel plate groove 104 of the top and bottom 101 and the screen light bracket 102 of each screen. Then, the corner bracket pin 701 is installed in the pin hole 703 and fixedly connected with the corner bracket 6 in the corner bracket cavity, so that the pins of the top and bottom 101 and the screen light bracket 102 of the two screens form a rectangular frame. Before the pins are assembled, the screen railing and the screen lock seat 4 need to be assembled between the top and bottom 101 and the screen light bracket 102. First, the top and bottom ends of the screen lock seat 4 are punched and milled to fit the round shape. The notch of the track protrusion 105 matches the shape of the screen lock seat 4 so that when it is placed vertically on the track protrusion, the bottom and top surfaces of the screen lock seat 4 can fit against the upper and lower parts 101 of the screen. A milling cutter is used to mill a lock hole on the side of the screen lock seat 4 to match the lock body 401. After milling, the screen lock seat 4 is placed in the groove on the side of any screen light fixture 102. When placing it, the side of the screen lock seat 4 with the milled lock hole should face away from the screen light fixture 102, with the unmilled side contacting the screen light fixture 102. Then, a long screw 702 is driven into the side of the screen light fixture 102 to fix the screen lock seat 4 in the groove. To better drive in the long screw 702, a hole saw can be used to first drill a hole on the side of the screen light fixture 102. After the long screw 702 is installed in the screw hole to fix the screen window lock seat 4, the screen window guardrail slidably installed between the upper and lower parts 101 of the screen window is assembled. The screen window guardrail consists of a single-groove guardrail 301, a double-groove guardrail 302, a pulley 9, and a screen window pressure line 303 that can be fastened to each single-groove guardrail 301 and double-groove guardrail 302. There is a single-groove guardrail 301 on each side of the screen window guardrail, and multiple double-groove guardrails 302 are set between the two single-groove guardrails 301. A mesh 5 is connected between the single-groove guardrails 301 and the double-groove guardrails 302, and between the double-groove guardrails 302. The mesh 5 is a foldable flexible diamond mesh made of 304 material.Furthermore, the distances between single-groove railing 301 and double-groove railing 302, and between two double-groove railings 302, are all less than 50cm. By controlling the distances between them, it is possible to prevent some people from deliberately damaging the screen 5 to enter the room. The two ends of the screen 5 are fixedly connected to the corresponding single-groove railing 301 or double-groove railing 302 by short screws. A lock body 401 is installed on the single-groove railing 301 near the screen lock seat 4. The single-groove railing 301, located away from the screen lock seat 4, is threadedly connected to the adjacent screen light bracket 102 via screws. Both the upper and lower ends of each double-groove railing 302 and the upper and lower ends of the single-groove railing 301 with the lock body 401 are detachably connected to pulleys 9 via screws. When installing the screen railing, the pulleys 9 must be coaxially installed with the circular track protrusions 105 on the upper and lower surfaces 101 of the screen to facilitate sliding of the screen railing on the upper and lower surfaces 101 of the screen.

[0025] Screen window pressing strips 305 are provided between the single pressing groove railing 301 and the screen window pressing line 303, and between the double pressing groove railing 302 and the screen window pressing line 303, to fill the gaps between the screen window pressing line 303 and the single pressing groove railing 301, and between the screen window pressing line 303 and the double pressing groove railing 302.

[0026] An insect-repellent strip 10 is installed on the outside of the screen frame 1. The insect-repellent strip 10 is made of EPDM material and is pasted on the top and bottom 101 of the screen of the screen frame 1. It can prevent mosquitoes from entering the room through the gaps in the installation of the screen railing.
