Description

Technical Field

[0001] This utility model belongs to the field of high-security door and window technology, specifically a high-security door and window with a multi-point locking structure. Background Technology

[0002] As residential buildings, schools, and nurseries place increasing emphasis on building safety, doors and windows, as key components connecting indoor and outdoor spaces, not only need to meet daily ventilation and lighting needs, but also bear the safety responsibility of preventing children from falling and resisting external impacts. In addition, in emergency situations such as fires and earthquakes, they also need to ensure that people can quickly escape through doors and windows. The market demand and application scenarios for high-safety doors and windows are becoming increasingly widespread.

[0003] Currently, high-security doors and windows on the market mainly improve security in two ways: one is to fix metal guardrails inside the window frame, which are rigidly connected to the window frame with bolts to form a physical protective barrier; the other is to use a single-point or double-point locking structure, which uses the cooperation of the lock tongue and the lock to fix the door and window sash to the window frame. Some products will also have simple limit blocks to prevent the doors and windows from being opened accidentally.

[0004] However, fixed guardrails cannot be quickly disassembled in emergencies, which can easily block escape routes and pose safety hazards. Most limiting and locking mechanisms are installed at low positions, which children can easily touch and operate, making it impossible to truly achieve fall protection and failing to meet the dual needs of "daily safety protection" and "emergency escape". Therefore, a high-security door and window with a multi-point locking structure is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a high-security door and window with a multi-point locking structure is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The high-security door and window with a multi-point locking structure of this utility model includes a window frame; the inner bottom wall of the window frame is rotatably connected to the window body through a pivot, the inner side wall of the window frame is fixedly connected to a limiting frame, one side of the limiting frame is provided with a through groove, and a protective frame is provided inside the window frame. A limiting mechanism is provided inside the window frame. The limiting mechanism includes a positioning plate fixedly connected to one side of the protective frame. A positioning groove is opened in the positioning plate. A fixing rod is fixedly connected to the inner wall of the positioning groove. A limiting block is slidably connected to the outer wall of the fixing rod. A positioning block is fixedly connected to the other end of the limiting block. The other end of the positioning block passes through the positioning plate and communicates with the outside. A first spring is sleeved on the outer wall of the fixing rod. By setting up the limiting mechanism, in conjunction with the limiting frame and the protective frame, the safety of children from falling can be enhanced, while the protective frame can be quickly dismantled in the event of a fire, facilitating escape.

[0007] Preferably, an auxiliary groove is provided on one side of the limiting frame, and an auxiliary block is fixedly connected to one side of the protective frame. The other end of the auxiliary block is inserted into the auxiliary groove. The auxiliary groove and the auxiliary block are used to assist in the positioning and movement limitation between the limiting frame and the protective frame.

[0008] Preferably, the protective frame has a fixing groove on one side near the positioning plate, and a plug-in block is slidably connected in the fixing groove. One end of the plug-in block is inserted into the positioning groove, and the other end of the plug-in block is fixedly connected to a toggle rod. The other end of the toggle rod passes through the protective frame and communicates with the outside. A second spring is sleeved on the outer wall of the toggle rod. The fixing groove, plug-in block, toggle rod and second spring can facilitate the formation of a second locking mechanism to lock the locking structure of the limiting mechanism and prevent the positioning block from moving due to strong winds, which would cause the limiting of the positioning plate to fail.

[0009] Preferably, the protective frame has a toggle groove on the side away from the positioning plate, and a toggle plate is fixedly connected to the outer wall of the toggle rod. The toggle groove and the toggle plate make it easy to move the plug block by pulling the toggle plate in conjunction with the toggle rod. The toggle groove hides the toggle plate and improves the aesthetics.

[0010] Preferably, an elastic pull strap is fixedly connected to the side of the actuating plate away from the actuating rod, and a sealing gasket is provided on the outer wall of the actuating plate. The actuating plate can be pulled by pulling the elastic pull strap to avoid the actuating plate being too embedded in the actuating groove and not finding a point of force application.

[0011] Preferably, the end of the positioning block away from the limiting block is set to a cone shape, which can eliminate the need to press the positioning block to install the positioning plate, simplifying the installation steps. A sealing gasket is provided at the point where the positioning block penetrates the positioning plate to improve sealing.

[0012] Preferably, the outer wall of the protective frame is provided with a sealing gasket to improve sealing performance, and the side of the limiting block near the positioning block is provided with a sealing gasket to improve sealing performance.

[0013] The beneficial effects of this utility model are: This utility model provides a high-security door and window with a multi-point locking structure. Through the setting of a limiting mechanism, in conjunction with a limiting frame and a protective frame, it can enhance the safety of children from falling while not hindering the rapid removal of the protective frame in the event of a fire, facilitating escape. The limiting frame is pre-fixed to the window frame by welding or bolting. Pulling the elastic strap moves one end of the plug-in block out of the positioning groove, pressing the side of the protective frame near the positioning plate against the limiting frame. One end of the positioning plate passes through the through groove, and one end of the auxiliary block is inserted into the auxiliary groove. One side of the positioning block abuts against the side of the limiting frame away from the protective frame. Releasing the elastic strap resets the plug-in block, limiting the movement of the two positioning blocks. The limiting mechanism is located high on the protective frame and the limiting frame, out of reach of children, further ensuring the safety and stability of the protective frame in preventing children from falling.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figures 1-4 This utility model provides a high-security door and window with a multi-point locking structure. It includes a window frame 1; the inner bottom wall of the window frame 1 is rotatably connected to a window body 2 via a pivot. The window body 2 and the window frame 1 together form a door and window as described in the prior art. Its sealing and locking are both existing mature technologies, so they will not be elaborated upon. A rectangular limiting frame 3 is fixedly connected to the inner side wall of the window frame 1. A through groove 4 is provided on one side of the limiting frame 3. A protective frame 5 is provided inside the window frame 1. The through groove 4 is located on the upper part of the side of the limiting frame 3 closest to the protective frame 5. A sealing gasket is provided on the outer wall of the protective frame 5 to improve sealing. An auxiliary groove 7 is provided on one side of the limiting frame 3. The auxiliary groove 7 is located at the bottom of the side of the limiting frame 3 near the protective frame 5 and is opposite to the through groove 4. An auxiliary block 8 is fixedly connected to one side of the protective frame 5. The other end of the auxiliary block 8 is inserted into the auxiliary groove 7. The auxiliary groove 7 and the auxiliary block 8 are used to assist in the positioning and movement limitation between the limiting frame 3 and the protective frame 5, and to limit the movement of the protective frame 5 in the tilt direction. A limiting mechanism 6 is provided inside the window frame 1. The limiting mechanism 6 includes a rectangular positioning plate 61 fixedly connected to one side of the protective frame 5. The positioning plate 61 is adapted to the size of the through groove 4. A positioning groove 62 is opened in the positioning plate 61. A fixing rod 63 is fixedly connected to the inner side wall of the positioning groove 62. A limiting block 64 is slidably connected to the outer wall of the fixing rod 63. A sealing gasket is provided on the side of the limiting block 64 near the positioning block 65 to improve the sealing performance. The other end of the limiting block 64 is fixedly connected to the positioning block 65. The other end of the positioning block 65 passes through the positioning plate 61 and communicates with the outside. A first spring 66 is sleeved on the outer wall of the fixing rod 63. The first spring 66 is located at the end of the limiting block 64 away from the positioning block 65. By setting up the limiting mechanism 6, together with the limiting frame 3 and the protective frame 5, the safety of children from falling can be enhanced, while the protective frame 5 can be quickly removed in the event of a fire, facilitating escape. A fixing groove 9 is provided on one side of the protective frame 5 near the positioning plate 61. A plug-in block 10 is slidably connected in the fixing groove 9. One end of the plug-in block 10 is inserted into the positioning groove 62. The other end of the plug-in block 10 is fixedly connected to a toggle rod 11. The other end of the toggle rod 11 passes through the protective frame 5 and communicates with the outside. A second spring 12 is sleeved on the outer wall of the toggle rod 11. By setting the fixed groove 9, the plug block 10, the toggle lever 11 and the second spring 12, a second locking can be easily formed to lock the locking structure of the limiting mechanism 6, so as to prevent the positioning block 65 from moving due to strong wind, which would cause the limiting of the positioning plate 61 to fail.

[0019] A sliding groove is provided on the side of the protective frame 5 away from the positioning plate 61. The sliding groove is opposite to the fixed groove 9. One end of the sliding rod 11 that passes through the protective frame 5 is located in the sliding groove. A sliding plate 13 is fixedly connected to the outer wall of the sliding rod 11. With the sliding groove and the sliding plate 13, it is easy to move the plug block 10 by pulling the sliding plate 13 in conjunction with the sliding rod 11. The sliding groove hides the sliding plate 13, improving the aesthetics. An elastic pull strap 14 is fixedly connected to the side of the toggle plate 13 away from the toggle lever 11, which can avoid affecting the closing of the window 2 and avoid motion interference. The outer wall of the toggle plate 13 is provided with a sealing gasket. The toggle plate 13 can be pulled by pulling the elastic pull strap 14, which can prevent the toggle plate 13 from being too embedded in the toggle groove and not finding the point of force. The end of the positioning block 65 away from the limiting block 64 is set to be tapered, so that the positioning plate 61 can be installed without pressing the positioning block 65, simplifying the installation steps. A sealing gasket is provided where the positioning block 65 passes through the positioning plate 61 to improve the seal.

[0020] Based on the above structure, this utility model includes the following implementation process: That is, the limiting frame 3 is fixed in the window frame 1 by welding or bolt positioning in advance, and then the elastic pull belt 14 is pulled and the toggle plate 13 and toggle rod 11 are used to drive the plug block 10 to move, so that one end of the plug block 10 located in the positioning groove 62 moves out. The protective frame 5 is pressed against the limiting frame 3 on the side closest to the positioning plate 61, so that one end of the positioning plate 61 passes through the through groove 4 and one end of the auxiliary block 8 is inserted into the auxiliary groove 7. During this process, the conical end of the positioning block 65 is in pre-contact with the limiting frame 3 and compressed into the positioning plate 61 until one side of the protective frame 5 abuts against the limiting frame 3. The pressure on the positioning block 65 is then released. Under the pressure of the first spring 66, the limiting block 64 drives the positioning block 65 to reset, and one end of the positioning block 65 moves out of the positioning plate 61. One side of the positioning block 65 then abuts against the limiting frame 3. The side away from the protective frame 5 abuts against the other side. At this time, the elastic pull bar can be released. Under the pressure of the second spring 12, the plug block 10 resets and one end is inserted into the positioning groove 62, which limits the movement of the two positioning blocks 65 so that the two positioning blocks 65 cannot move without pulling the actuating plate 13, thus ensuring the stability of the positioning plate 61 and the protective frame 5. Moreover, the limiting mechanism 6 is located at the height of the protective frame 5 and the limiting frame 3, where children cannot touch it, further ensuring the safety and stability of the protective frame 5 for preventing children from falling. When a fire occurs and it is necessary to break a window to escape, an adult can stand on the window frame 1, reach out of the protective frame 5, pull the elastic bar to move one end of the plug block 10 out of the positioning groove 62, and then press the two positioning blocks 65 back into the positioning groove 62. This will release the restriction on one end of the positioning plate 61 and the protective frame 5. After removing the protective frame 5, one can escape through the gap between the limiting frame 3.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
