Description

Technical Field

[0001] This invention belongs to the field of fire-resistant window technology, and in particular relates to a highly airtight fire-resistant window with a quick-opening device. Background Technology

[0002] Fire-resistant windows, as the name suggests, are windows that can meet fire integrity requirements for a certain period of time. "Fire integrity" refers to the window's ability to maintain its structural integrity during a fire, preventing flames and smoke from spreading to other areas and providing time for escape and rescue. Depending on the application and requirements, fire-resistant windows can be categorized into various types, including single-pane fire-resistant windows, multi-pane fire-resistant windows, composite material fire-resistant windows, and stainless steel fire-resistant windows.

[0003] With the advancement of technology and the improvement of building safety standards, the performance and quality of fire-resistant windows are constantly improving, providing a more solid guarantee for our life and property safety. Whether it is a high-rise residential building, a commercial complex or an industrial plant, fire-resistant windows need to be installed to ensure the safety of the building. Especially in some densely populated places with high fire risk, such as hospitals, schools and libraries, fire-resistant windows are an indispensable safety facility.

[0004] Currently, existing fire-resistant windows have complex structures and are heavy to operate. Opening them requires cumbersome steps, which wastes a lot of time when opening or closing them. As a result, in the event of a fire, the fire-resistant windows cannot be opened quickly to allow users to escape in time, and their effectiveness is poor.

[0005] To address this issue, we designed a highly airtight fire-resistant window with a quick-opening mechanism. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] The present invention is a high-sealing fire-resistant window with a quick-opening device, comprising an outer frame, a first inner frame and a second inner frame. The first inner frame is installed inside one side of the outer frame. A sliding groove is provided on the inner wall of the first inner frame. Two first heat-resistant glass panes are installed opposite each other on the inner side of the first inner frame. The two first heat-resistant glass panes are arranged opposite each other on both sides of the sliding groove. The second inner frame is movably engaged with the sliding groove. A second heat-resistant glass pane is installed on the inner wall of the second inner frame.

[0008] A groove is formed on the inner wall of the outer frame away from the first inner frame. Several positioning grooves are formed on the front side of the inner wall of the groove. A movable groove is formed on the inner side of the second inner frame away from the first inner frame. A through groove is formed on one side of the inner wall of the movable groove. A movable plate is movably arranged inside the movable groove. The movable plate cooperates with the through groove. Several first springs are connected between the rear surface of the movable plate and the inner wall of the movable groove. Several positioning blocks are fixed on the side of the movable plate away from the first springs, which cooperate with the positioning groove.

[0009] The inner wall of the movable groove has several circular holes on the front side. The circular holes penetrate the front surface of the second inner frame. A push rod is movably installed in the circular hole, and one end of the push rod is fixedly connected to the movable plate at the rear side.

[0010] An active cavity is provided on the side of the second inner frame away from the active groove. An avoidance groove is provided on the upper side of the second inner frame. The two ends of the avoidance groove are respectively connected to the active groove and the active cavity. A steel rope is movably arranged in the avoidance groove. A connecting rod is fixed on the side of the active plate near the first spring. A lifting plate is movably arranged inside the active cavity. The two ends of the steel rope are respectively fixedly connected to the connecting rod and the lifting plate. A pressing block is fixed at the bottom of the lifting plate.

[0011] Two wedge-shaped blocks are arranged opposite each other on the lower side of the movable cavity. The inclined surfaces on both sides of the extrusion block cooperate with the two wedge-shaped blocks respectively. A locking block is fixed at the end of the wedge-shaped block away from the extrusion block. Two through holes are connected opposite each other on the lower side of the inner wall of the movable cavity. Two locking grooves are opened opposite each other on the inner wall of the sliding groove. The locking block cooperates with the through holes and the locking grooves.

[0012] Two limiting rods are fixed to each other on the top of the inner side of the movable cavity. Both limiting rods pass through the lifting plate, and the lifting plate slides with the limiting rods. A second spring is connected between the top of the lifting plate and the inner wall of the movable cavity, and the second spring is sleeved on the outside of the steel rope.

[0013] Inside the movable cavity, there are two horizontal bars fixed to each other on the lower side. Two limiting plates are slidably sleeved on the horizontal bars. The limiting plates are fixedly connected to the adjacent wedge blocks. A third spring is fixedly connected between the side of the limiting plate near the through hole and the inner wall of the movable cavity. The third spring is sleeved on the outside of the horizontal bars.

[0014] A grip is fixed between the front ends of several push rods, and several fixed rods are fixed inside the movable groove. The fixed rods pass through the movable plate, and the movable plate and the fixed rods slide together. The first spring is sleeved on the outside of the fixed rods. A pulley group is fixed at the top of the inner side of the movable groove, and the steel rope cooperates with the pulley group.

[0015] The inner wall of the outer frame is provided with T-shaped grooves on both the upper and lower sides. A T-shaped block is slidably disposed inside the T-shaped groove, and the outer side of the T-shaped block is fixedly connected to the second inner frame.

[0016] The present invention has the following beneficial effects:

[0017] This invention facilitates the adjustment of the second inner frame to slide outward through the movable cooperation between the second inner frame and the sliding groove, until the outermost end of the movable plate is inserted into the groove. At this time, the second inner frame contacts the side of the outer frame's inner wall away from the first inner frame. With the cooperation of the first and second heat-resistant glass, the fire-resistant window is closed. Under the elastic action of the first spring, the movable plate is easily pressed forward, thereby driving the positioning block to insert into the corresponding positioning groove, achieving the purpose of connecting the second inner frame and the outer frame together, ensuring the stability of the fire-resistant window, facilitating the use of the fire-resistant window, and having a simple structure and convenient use.

[0018] Under the elastic action of the second spring, the lifting plate is easily pressed downward, which in turn drives the pressing block to move downward. Combined with the mutual cooperation between the inclined surfaces on both sides of the pressing block and the two wedge blocks, it is easy to press the two wedge blocks to both sides, which in turn drives the locking block to pass through the through hole and insert into the corresponding locking groove, thus realizing the purpose of connecting the first inner frame and the second inner frame together, further ensuring the overall stability of the fire-resistant window when closed.

[0019] The combination of the grip and push rod allows the movable plate to be pushed backward, causing the positioning block to disengage from its corresponding positioning groove. Simultaneously, the steel cable pulls the lifting plate upward, causing the pressing block to move away from the wedge block. Combined with the elasticity of the third spring and the limiting plate, the wedge block is restored to its initial position, which in turn causes the locking block to disengage from the locking groove. This facilitates the quick opening of the second inner frame, enabling the fire-resistant window to be opened rapidly, allowing users to escape quickly in the event of a fire.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0037] Please see Figures 1-11 As shown, the present invention is a high-sealing fire-resistant window with a quick-opening device, including an outer frame 1, a first inner frame 2 and a second inner frame 5. The first inner frame 2 is installed inside one side of the outer frame 1. A sliding groove 3 is provided on the inner wall of the first inner frame 2. Two first heat-resistant glass 4 are installed opposite each other on the inner side of the first inner frame 2. The two first heat-resistant glass 4 are arranged opposite each other on both sides of the sliding groove 3. The second inner frame 5 is movably engaged with the sliding groove 3. A second heat-resistant glass 6 is installed on the inner wall of the second inner frame 5.

[0038] A groove 10 is provided on the inner wall of the outer frame 1 away from the first inner frame 2. Several positioning grooves 11 are provided on the front side of the inner wall of the groove 10. A movable groove 7 is provided on the inner wall of the second inner frame 5 away from the first inner frame 2. A through groove is provided on one side of the inner wall of the movable groove 7. A movable plate 8 is movably arranged inside the movable groove 7. The movable plate 8 cooperates with the through groove. Several first springs 9 are connected between the rear surface of the movable plate 8 and the inner wall of the movable groove 7. Several positioning blocks 12 are fixed on the side of the movable plate 8 away from the first springs 9, which cooperate with the positioning grooves 11.

[0039] Several round holes are provided on the front side of the inner wall of the movable groove 7. The round holes penetrate the front surface of the second inner frame 5. A push rod 13 is movably installed in the round hole. The rear end of the push rod 13 is fixedly connected to the movable plate 8.

[0040] In the above structure, the second inner frame 5 and the sliding groove 3 are movable together, which facilitates the adjustment of the second inner frame 5 to slide outward until the outer end of the movable plate 8 is inserted into the groove 10. At this time, the second inner frame 5 and the inner wall of the outer frame 1 are in contact with the side away from the first inner frame 2. With the cooperation of the first heat-resistant glass 4 and the second heat-resistant glass 6, the fire-resistant window is closed. Under the elastic action of the first spring 9, the movable plate 8 is easily pressed forward, which in turn drives the positioning block 12 to be inserted into the corresponding positioning groove 11. This achieves the purpose of connecting the second inner frame 5 and the outer frame 1 together, ensuring the stability of the fire-resistant window, facilitating the use of the fire-resistant window, and making the structure simple and easy to use.

[0041] At the same time, under the action of the push rod 13, it is easy to push the movable plate 8 to the rear, causing the positioning block 12 to disengage from the corresponding positioning groove 11, so as to quickly push open the second inner frame 5, thereby realizing the rapid opening of the fire-resistant window, which allows users to escape quickly in the event of a fire.

[0042] An active cavity 14 is provided on the side of the second inner frame 5 away from the active groove 7. An avoidance groove is provided on the upper side of the second inner frame 5. The two ends of the avoidance groove are connected to the active groove 7 and the active cavity 14 respectively. A steel rope 15 is movably arranged in the avoidance groove. A connecting rod 16 is fixed on the side of the active plate 8 near the first spring 9. A lifting plate 17 is movably arranged inside the active cavity 14. The two ends of the steel rope 15 are fixedly connected to the connecting rod 16 and the lifting plate 17 respectively. An extrusion block 18 is fixed at the bottom of the lifting plate 17.

[0043] Two wedge-shaped blocks 19 are arranged opposite each other on the lower side of the movable cavity 14. The inclined surfaces on both sides of the extrusion block 18 cooperate with the two wedge-shaped blocks 19 respectively. A locking block 21 is fixed at the end of the wedge-shaped block 19 away from the extrusion block 18. Two through holes are connected opposite each other on the lower side of the inner wall of the movable cavity 14. Two locking grooves 20 are opened opposite each other on the inner wall of the sliding groove 3. The locking block 21 cooperates with the through holes and the locking grooves 20.

[0044] Two limiting rods 22 are fixed to each other on the top of the inner side of the movable cavity 14. Both limiting rods 22 pass through the lifting plate 17, and the lifting plate 17 slides with the limiting rods 22. A second spring 23 is connected between the top of the lifting plate 17 and the inner wall of the movable cavity 14. The second spring 23 is sleeved on the outside of the steel rope 15.

[0045] Under the elastic action of the second spring 23, the lifting plate 17 is easily pressed downward, which in turn drives the pressing block 18 to move downward. Combined with the mutual cooperation between the inclined surfaces on both sides of the pressing block 18 and the two wedge blocks 19, the two wedge blocks 19 are easily pressed to both sides, which in turn drives the locking block 21 to pass through the through hole and insert into the corresponding locking groove 20. This achieves the purpose of connecting the first inner frame 2 and the second inner frame 5 together, further ensuring the overall stability of the fire-resistant window when closed.

[0046] Inside the movable cavity 14, there are two horizontal bars 24 fixedly fixed to each other on the lower side. Two limiting plates 25 are slidably sleeved on the horizontal bars 24. The limiting plates 25 are fixedly connected to the adjacent wedge blocks 19. A third spring 26 is fixedly connected between the side of the limiting plate 25 near the through hole and the inner wall of the movable cavity 14. The third spring 26 is sleeved on the outside of the horizontal bars 24.

[0047] A gripping rod 27 is fixed between the front ends of several push rods 13. Several fixed rods 28 are fixed inside the movable groove 7. The fixed rods 28 pass through the movable plate 8 and slide with the movable plate 8. The first spring 9 is sleeved on the outside of the fixed rod 28. A pulley group 31 is fixed at the top of the inner side of the movable groove 7. The steel rope 15 cooperates with the pulley group 31.

[0048] T-shaped grooves 29 are provided on both the upper and lower sides of the inner wall of the outer frame 1. T-shaped blocks 30 are slidably arranged inside the T-shaped grooves 29. The outer side of the T-shaped blocks 30 is fixedly connected to the second inner frame 5.

[0049] Example:

[0050] During use, when closing the fireproof window, first push the handle 27 backward, which, together with the push rod 13, causes the movable plate 8 to move backward, compressing the first spring 9;

[0051] At this time, under the action of the pulley block 31, combined with the connecting rod 16, the end of the steel rope 15 close to the movable plate 8 moves to the rear and pulls the lifting plate 17 upward to squeeze the second spring 23.

[0052] Then, with the sliding engagement of the second inner frame 5 and the sliding groove 3, and the sliding engagement of the T-shaped block 30 and the T-shaped groove 29, the second inner frame 5 is pulled to move outward along the sliding groove 3 until the exposed end of the movable plate 8 is moved into the groove 10.

[0053] At this time, the grip bar 27 is released. Under the elastic action of the first spring 9, combined with the sliding cooperation between the movable plate 8 and the fixed rod 28, the movable plate 8 is pressed forward, which in turn drives the positioning block 12 to insert into the corresponding positioning groove 11, so that the second inner frame 5 and the outer frame 1 are inserted together.

[0054] During the forward compression of the movable plate 8, the connecting rod 16 causes the end of the steel rope 15 near the movable plate 8 to return to its initial position. Combined with the elasticity of the second spring 23 and the sliding cooperation between the lifting plate 17 and the limiting rod 22, the lifting plate 17 moves downward stably, causing the compression block 18 to move downward. With the cooperation of the inclined surfaces on both sides of the compression block 18 with the two wedge blocks 19, the two wedge blocks 19 are compressed to both sides. Under the action of the limiting plate 25, the third spring 26 is compressed, which in turn causes the locking block 21 to pass through the through hole and insert into the corresponding locking groove 20, thus achieving the purpose of connecting the first inner frame 2 and the second inner frame 5 together, further ensuring the overall stability of the fire-resistant window in the closed state.

[0055] like Figure 11As shown, when a fire breaks out and it is necessary to quickly open the fire-resistant window to escape, hold the handle 27 and push it backward. Under the action of the push rod 13, it is pushed backward through the movable plate 8, which in turn causes the positioning block 12 to disengage from the corresponding positioning groove 11. At the same time, under the action of the connecting rod 16 and the pulley group 31, one end of the steel rope 15 is pulled backward, which in turn pulls the lifting plate 17 to move upward, causing the squeezing block 18 to move upward away from the wedge block 19. At this time, under the elastic action of the third spring 26, combined with the limiting plate 25, the wedge block 19 is moved towards the initial position, which in turn causes the locking block 21 to disengage from the corresponding locking groove 20.

[0056] At this time, the second inner frame 5 is pulled into the sliding groove 3 to quickly open the fire-resistant window, facilitating the user's escape.

[0057] It should be further noted that the installation structure, connection method, or setting method of each component in this invention are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.
