Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a fire rescue window that also has anti-theft function. Background Technology

[0002] Fire rescue windows are a common feature in various fire protection systems. They are typically made of breakable glass and marked with the "Fire Rescue Window" sign. In the event of a fire, firefighters can break the glass to enter the building and conduct rescue operations.

[0003] However, according to the Ministry of Public Security, rooms containing easily explosive or highly toxic chemicals in Class A warehouses within integrated circuit and flat panel display factories should be fitted with security grilles. Currently, these grilles are mostly welded directly to the outside of the glass windows. In the event of a fire, firefighters need to use fire-fighting spreaders to break through the grilles, which delays rescue efforts and sacrifices valuable rescue time.

[0004] Therefore, how to meet the safety requirements of the workshop while effectively improving rescue efficiency has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a fire rescue window that also has anti-theft function, so as to meet the security needs of the workshop and effectively improve the rescue efficiency.

[0006] This utility model provides a fire rescue window with anti-theft function, including a shell, an anti-theft window, a linkage mechanism, a limiting mechanism, a first shaft, and a limiting part. The shell and the limiting part are installed on the wall and are spaced apart along the direction of gravity. At least a part of the linkage mechanism, the limiting mechanism, and the first shaft are disposed inside the shell. The first shaft is connected to the shell, and the linkage mechanism is rotatably connected to the first shaft. The linkage mechanism includes a hook. Along the direction of gravity, at least a part of the limiting mechanism and the hook are respectively disposed on both sides of the first shaft. When the limiting mechanism abuts against the linkage mechanism, the anti-theft window is hung on the hook, and the limiting part is used to restrict the movement of the anti-theft window. When the limiting mechanism separates from the linkage mechanism, the linkage mechanism is used to rotate around the first shaft, the hook separates from the anti-theft window, and the anti-theft window slides out of the limiting part.

[0007] The fire rescue window provided by this utility model allows the limiting mechanism and the linkage mechanism to engage when no fire occurs in the workshop. In this state, the security window is hung on the hook, and the limiting part restricts the window's movement in other directions, thus fulfilling the security requirements of the fire rescue window. However, in the event of a fire or other emergency in the workshop, the limiting mechanism and the linkage mechanism can be quickly separated. The linkage mechanism then rotates around the first axis, causing the hook to separate from the security window. Simultaneously, the security window automatically slides out of the limiting part under its own weight, effectively increasing the speed of dismantling the security window, shortening rescue time, and improving rescue efficiency.

[0008] In one possible implementation of this utility model, the fire rescue window also includes a smoke sensor, which is used to monitor smoke signals; when the smoke sensor detects a smoke signal, the limiting mechanism separates from the linkage mechanism, and the anti-theft window slides out of the limiting part.

[0009] In one possible implementation of this utility model, the linkage mechanism includes a first link, a second link, and an elastic element. The first link is hinged to the second link via a hinge shaft, and the second link includes a hook. The elastic element is disposed in the opening area formed by the first and second links, with one end connected to the first link and the other end connected to the hook. A first shaft is located between the hinge shaft and the elastic element and is rotatably connected to the second link. When the limiting mechanism abuts against the first link, the security window is hung on the hook, and the elastic element is in a stretched state. When the limiting mechanism separates from the linkage mechanism, the elastic element is used to drive the hook to rotate in a direction away from gravity.

[0010] In one possible implementation of this utility model, the fire rescue window further includes a second axis, which is spaced apart from the first axis and parallel to each other along the direction of gravity; the second axis is connected to the outer shell, and the axis of the second axis is perpendicular to the direction of gravity; the first connecting rod is provided with an elongated hole, and the second axis is inserted into the elongated hole; when the limiting mechanism abuts against the first connecting rod, along the stretching direction of the elastic element, the side wall of the second axis abuts against the long side of the elongated hole opposite to the hook; when the limiting mechanism separates from the connecting rod mechanism, the first connecting rod is used to slide relative to the second axis along the long side of the elongated hole.

[0011] In one possible implementation of this utility model, the position where the elastic element is connected to the first link is away from the hinge axis relative to the second axis.

[0012] In one possible implementation of this utility model, the first link includes an abutment portion that protrudes from the side wall of the first link and is located between the second shaft and the hinge shaft, and a limiting mechanism is used to abut against the abutment portion.

[0013] In one possible implementation of this utility model, the limiting mechanism includes a telescopic rod for extending and retracting along the direction of gravity; the abutting part includes a limiting hole; when the telescopic rod is inserted into the limiting hole, a portion of the side wall of the telescopic rod abuts against a portion of the side wall of the limiting hole, and the burglarproof window is hung on the hook.

[0014] In one possible implementation of this utility model, the fire rescue window also includes a protective structure. When the burglarproof window is hung on the hook, at least part of the protective structure is disposed between the ground and the burglarproof window along the direction of gravity, and is in contact with the burglarproof window or has a gap there; when the limiting mechanism and the linkage mechanism are separated, the protective structure is located outside the sliding trajectory of the burglarproof window.

[0015] In one possible implementation of this utility model, the protective structure includes an electromagnetic switch and a telescopic part. When the burglarproof window is hung on the hook, the telescopic part is located between the ground and the burglarproof window along the direction of gravity, and is in contact with the burglarproof window or has a gap; the electromagnetic switch is used to control the extension and retraction of the telescopic part.

[0016] In one possible implementation of this utility model, the limiting part includes a limiting groove, the long side of which is arranged along the direction of gravity; when the burglarproof window is hung on the hook, the edge of the burglarproof window is inserted into the limiting groove.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this utility model are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the protection scope of this utility model. The accompanying drawings of the embodiments of this utility model are only for illustrating relative positional relationships and do not represent actual proportions.

[0020] It should be noted that specific details are set forth in the following description to facilitate understanding of this utility model. However, this utility model can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Fire rescue windows are a common feature in various fire protection systems. They are typically made of breakable glass and marked with the "Fire Rescue Window" sign. In the event of a fire, firefighters can break the glass to enter the building and conduct rescue operations.

[0022] However, according to the requirements of the Ministry of Public Security, rooms storing easily explosive and highly toxic chemicals in Class A warehouses within integrated circuit and flat panel display factories should be equipped with anti-theft grilles. For example, Article 5.2.6 of the "Security Requirements for Storage Sites of Highly Toxic Chemicals and Radioactive Sources" (GA1002-2012) stipulates that windows and ventilation openings in warehouses, security duty rooms, and monitoring centers should be equipped with anti-theft grilles. The steel grilles should use solid steel bars with a diameter of not less than 12mm. Article 7.10 of the "Security Requirements for Storage Sites of Easily Explosive Hazardous Chemicals" (GA1511-2018) stipulates that steel grilles used in storage sites should use solid steel bars with a diameter greater than or equal to 12mm; steel pipe grilles should use steel pipes with a diameter greater than or equal to 20mm and a wall thickness greater than or equal to 2mm. Currently, most anti-theft grilles are directly welded to the outside of glass windows. In the event of a fire, firefighters need to use fire-fighting spreaders to break through the grilles, which delays rescue efforts and sacrifices valuable rescue time.

[0023] In view of this, the fire rescue window with anti-theft function provided by this utility model is installed in the workshop to meet the workshop's security needs. Furthermore, in the event of a fire, the anti-theft window can automatically detach to effectively shorten rescue time and improve rescue efficiency. To make the purpose, technical solution, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings and specific embodiments.

[0024] refer to Figure 1 and Figure 2 , Figure 1 A structural diagram used to illustrate a fire rescue window; Figure 2 For display Figure 1 A top view of the provided fire rescue window. The fire rescue window includes a glass window 1 and a security window 2, with the glass window 1 connected to the workshop wall 01 via a window frame 02. The security window 2 is installed inside the workshop and covers the glass window 1 to meet security requirements.

[0025] Also, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 3 For display Figure 2 A sectional view along point AA. The fire rescue window also includes a housing 3, a linkage mechanism 4, a limiting mechanism 5, a first shaft 6, and a limiting part 7, wherein the housing 3 and the limiting part 7 are mounted on the wall 01 and along the direction of gravity ( Figure 1 The negative direction of the Z-axis is shown. It can be understood that the housing 3 is positioned relative to the limiting part 7 in the positive direction of the Z-axis. At least a part of the linkage mechanism 4, the limiting mechanism 5, and the first shaft 6 are all disposed inside the housing 3, and the first shaft 6 is connected to the housing 3. Specifically, the end of the first shaft 6 can be fixedly connected to the side wall of the housing 3 by fasteners or welded to the side wall of the housing 3. It can be understood that the first shaft 6 can also be inserted into the side wall of the housing 3, that is, a rotatable connection is formed between the two. The specific configuration can be set according to the actual installation requirements.

[0026] It should be noted that the shape of the outer shell 3 is not limited in this utility model. For example, the outer shell 3 can be a cubic structure, and the outer shell 3 can be installed on the upper frame of the wall 01 or the window frame 02 by fasteners. It is understood that since the burglarproof window 2 needs to cover the glass window 1, the outer shell 3 is located above the glass window 1, that is, the direction of the outer shell 3 to the glass window 1 is the direction of gravity.

[0027] In the specific configuration of the linkage mechanism 4, the linkage mechanism 4 can include a hook 41, and the linkage mechanism 4 is rotatably connected to the first shaft 6, so that the linkage mechanism 4 can rotate around the first shaft 6. Simultaneously, at least a portion of the limiting mechanism 5 and the hook 41 can be respectively disposed on both sides of the first shaft 6, and the hook 41 is used to hang the security window 2. For example, the long side of the outer casing 3 is along the long side direction of the upper frame of the window frame 02, and the axis of the first shaft 6 is parallel to the long side of the outer casing 3. In addition, an opening is provided at the bottom of the outer casing 3 for the hook 41 to extend out of the outer casing 3.

[0028] When specifically setting the limit part 7, options include, for example... Figure 4 As shown, Figure 4 For display Figure 1A sectional view of the fire rescue window sill BB is provided. The limiting part 7 may include a limiting groove 71, the long side of which is set along the direction of gravity, and when the security window 2 is hung on the hook 41, the edge of the security window 2 is inserted into the limiting groove 71. Specifically, the limiting part 7 may be set as a U-shaped channel steel, and the channel steel is installed on the left side frame or the right side frame of the wall 01 or window frame 02. It is understood that the fire rescue window may include two channel steels, and the two channel steels are set one-to-one with the left side frame and the right side frame, and the openings of the two U-shaped channel steels are opposite each other. After the left edge and / or right edge of the security window 2 is inserted into the corresponding channel steel, the side wall of the channel steel will limit the security window 2 to restrict the movement of the security window 2 toward and away from the surface of the wall 01. In addition, the bottom wall of the channel steel may also limit the movement of the security window 2 along the extension direction of the surface of the wall 01 to further enhance the reliability of the security window 2. The hook 41 can restrict the movement of the security window 2 along the direction of gravity. On the other hand, since the security window 2 is generally in the shape of a fence, the gap between the fences is located on the hook 41. Therefore, the hook 41 can also restrict the left and right movement distance of the security window 2.

[0029] It is worth mentioning that along the length of the upper frame of the window frame 02, multiple corresponding linkage mechanisms 4 and limiting mechanisms 5 can be set at intervals to further improve the security and reliability of the fire rescue window.

[0030] The fire rescue window provided by this utility model allows the limiting mechanism 5 to abut against the linkage mechanism 4 when no fire occurs in the workshop. At this time, the security window 2 is hung on the hook 41, and the limiting part 7 restricts the movement of the security window 2 in other directions, thus meeting the security requirements of the fire rescue window. However, in the event of a fire or other emergency in the workshop, the limiting mechanism 5 and the linkage mechanism 4 can be quickly separated. The linkage mechanism 4 then rotates around the first axis 6, causing the hook 41 to separate from the security window 2. Simultaneously, the security window 2 automatically slides out of the limiting part 7 under its own weight, effectively increasing the removal speed of the security window 2, shortening rescue time, and improving rescue efficiency.

[0031] It is worth mentioning that the fire rescue window may also include a smoke sensor and a control module. The smoke sensor is installed inside the workshop to monitor smoke signals. When the smoke sensor detects a smoke signal, the control module controls the limit mechanism 5 to automatically separate from the linkage mechanism 4, which helps to further shorten rescue time and improve rescue efficiency.

[0032] Optionally, the limiting mechanism 5 may include a telescopic rod 51, which extends and retracts along the direction of gravity. Alternatively, the limiting mechanism 5 may include an electromagnetic switch. In the absence of an emergency such as a fire in the workshop, the electromagnetic switch remains de-energized. Simultaneously, the telescopic rod 51 extends and abuts against the linkage mechanism 4, and the security window 2 is hung on the hook 41 to maintain the stability of the linkage mechanism 4 and the security window 2. In the event of an emergency in the workshop, the control module energizes the electromagnetic switch, causing the telescopic rod 51 to retract, thus automatically separating the telescopic rod 51 from the connecting mechanism.

[0033] It should be noted that the control process of the control module and the electromagnetic switch are existing technologies and will not be elaborated here.

[0034] When specifically setting up the connection mechanism, such as Figure 3 As shown, in an optional embodiment, the linkage mechanism 4 includes a first link 42, a second link 43, and an elastic element 44. The first link 42 is hinged to the second link 43 via a hinge shaft 45. The second link 43 includes a hook 41, and the elastic element 44 is disposed in the opening area formed by the first link 42 and the second link 43. One end of the elastic element 44 is connected to the first link 42, and the other end is connected to the hook 41. It should be noted that the elastic element 44 can be exemplarily a spring, and the elastic force of the spring can be adjusted according to the weight of the security window 2.

[0035] The first shaft 6 is located between the hinge shaft 45 and the elastic element 44, and is rotatably connected to the second connecting rod 43. When the limiting mechanism 5 abuts against the first connecting rod 42, the security window 2 is hung on the hook 41, the elastic element 44 is in a stretched state, and the tension of the elastic element 44 is F, the weight of the security window 2 is G, and F > G. After the limiting mechanism 5 separates from the first connecting rod 42, the elastic element 44 can drive the first connecting rod 42 to move around the hinge shaft 45 toward the second connecting rod 43. At the same time, the elastic element 44 drives the hook 41 of the second connecting rod 43 to rotate in the direction away from gravity, that is, the included angle between the first connecting rod 42 and the second connecting rod 43 decreases. Understandably, since the first link 42 and the second link 43 are hinged, and the second link 43 is rotatably connected to the first shaft 6, the hook 41 can rotate around the first shaft 6 in a direction away from gravity under the drive of the elastic element 44, so as to effectively separate the hook 41 from the security window 2, thereby improving rescue efficiency and simplifying the linkage mechanism 4.

[0036] Additionally, as the hook 41 rotates, it will cause the security window 2 to move a certain distance. Therefore, when the security window 2 is hung on the hook 41, if... Figure 4 As shown, a gap can be created between the side wall of the U-shaped channel steel and the security window 2, and this gap is greater than or equal to the travel distance of the security window 2 between the side walls of the U-shaped channel steel.

[0037] Continue to refer to Figure 3 In one optional embodiment, the fire rescue window further includes a second axis 8, which is spaced apart from the first axis 6 along the direction of gravity. The first axis 6 and the second axis 8 are parallel to each other, and the second axis 8 is connected to the outer shell 3. Meanwhile, the axis of the second axis 8 is perpendicular to the direction of gravity.

[0038] Meanwhile, the first connecting rod 42 is provided with an elongated hole 421, and the second shaft 8 is inserted into the elongated hole 421. When the limiting mechanism 5 abuts against the first connecting rod 42, along the stretching direction of the elastic member 44, the side wall of the second shaft 8 abuts against the long side of the elongated hole 421 opposite to the hook 41, in order to maintain the stability of the elastic member 44. Furthermore, when the limiting mechanism 5 separates from the linkage mechanism 4, the first connecting rod 42 can slide relative to the second shaft 8 along the long side of the elongated hole 421, thereby achieving effective separation of the hook 41 from the security window 2 while simplifying the linkage mechanism 4.

[0039] In addition, the position where the elastic element 44 is connected to the first link 42 can be made to be away from the hinge axis 45 relative to the second axis 8. Then, if the opening angle of the first link 42 and the second link 43 remains unchanged, it is beneficial to increase the stretchable length of the elastic element 44, that is, to increase the tensile force without plastic deformation of the elastic element 44, so as to improve the adaptability to security windows 2 of different weights.

[0040] In one alternative implementation, such as Figure 3 As shown, the first connecting rod 42 includes an abutment portion 422, which protrudes from the side wall of the first connecting rod 42 and is located between the second shaft 8 and the hinge shaft 45. The limiting mechanism 5 is used to abut against the abutment portion 422. The abutment portion 422 can be, for example, a plate-shaped protrusion protruding from the side wall of the first connecting rod 42, and there is an included angle α between the plate surface and the first connecting rod 42, where α > 90°, and α = 120° for example. The telescopic rod 51 extends and retracts along the direction of gravity, and the abutment portion 422 includes a limiting hole, the axis of which is, for example, along the direction of gravity. Thus, when the burglarproof window 2 is hung on the hook 41, and the telescopic rod 51 is inserted into the limiting hole, and the side wall of the telescopic rod 51 abuts against the side wall of the limiting hole, the connecting rod mechanism 4 is stable as a whole, and the burglarproof window 2 can be stably hung on the hook 41. It simplifies the connection between the limiting mechanism 5 and the linkage mechanism 4 while ensuring the reliability of the connection. Furthermore, the diameter of the limiting hole can be greater than or equal to the diameter of the telescopic rod 51; this can be adjusted according to actual needs and is not specifically limited here.

[0041] Understandably, the limiting mechanism 5 may include a mechanism housing, and the telescopic rod 51 extends out of or retracts into the mechanism housing, and the mechanism housing may be fixedly connected to the outer shell 3.

[0042] Optional, such as Figure 5 As shown, Figure 5 Another structural schematic diagram is used to illustrate the linkage mechanism 4. In this diagram, α = 90°, and the end of the telescopic rod 51 of the limiting structure is opposite to the plate surface, that is, the axis of the telescopic rod 51 is perpendicular to the plate surface of the abutment part 422. This allows the stability requirements of the linkage mechanism 4 to be met by having the end of the telescopic rod 51 abut against the plate surface.

[0043] In an alternative implementation, the fire rescue window may also include a protective structure 9, such as... Figure 6 As shown, Figure 6 A schematic diagram illustrating the protective structure 9. When the security window 2 is hung on the hook 41, at least a portion of the protective structure 9 is positioned between the ground and the security window 2 along the direction of gravity, and is either in contact with the security window 2 or has a gap. This effectively reduces the risk of the security window 2 falling directly to the ground and causing damage when the linkage mechanism 4 fails due to its service life or other reasons.

[0044] When the limiting mechanism 5 and the linkage mechanism 4 are normally separated, the protective structure 9 can automatically move to the outside of the sliding trajectory of the burglar window 2 to meet the disassembly requirements of the burglar window 2.

[0045] Furthermore, in the specific configuration of the protective structure 9, the protective structure 9 includes an electromagnetic switch and a telescopic part 91. When the security window 2 is hung on the hook 41, along the direction of gravity, the telescopic part 91 is positioned between the ground and the security window 2, either in contact with the security window 2 or with a gap, and the electromagnetic switch is in the de-energized state. In the event of a fire or other accident, the control module energizes the electromagnetic switch to control the retraction of the telescopic part 91. This simplifies the protective structure 9 while meeting its usage requirements. It is understood that the telescopic part 91 can be housed within the casing of the protective structure 9, and the casing of the protective structure 9 can be fixedly connected to the lower frame of the wall 01 or the window frame 02.

[0046] It is worth mentioning that in the event of an emergency where no fire occurs in the workshop, the electromagnetic switch is always de-energized and is only energized in the event of an emergency to retract the telescopic part 91 or the telescopic rod 51. Therefore, it helps to reduce energy consumption and lower costs.

[0047] In summary, the fire rescue window provided by this utility model allows the limiting mechanism 5 to abut against the linkage mechanism 4 when no fire occurs in the workshop. At this time, the security window 2 is hung on the hook 41, and the limiting part 7 restricts the movement of the security window 2 in other directions to meet the security requirements of the fire rescue window. When a fire or other emergency occurs in the workshop, the limiting mechanism 5 and the linkage mechanism 4 can be quickly separated. The linkage mechanism 4 then rotates around the first axis 6, causing the hook 41 to separate from the security window 2. At the same time, the security window 2 automatically slides out of the limiting part 7 under its own weight, thereby effectively increasing the removal speed of the security window 2, shortening the rescue time, and improving rescue efficiency.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
