Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window breaking devices, and in particular to a door and window breaking device for fire fighting and rescue. Background Technology
[0002] Firefighting and rescue door and window breaking devices are tools specifically designed for firefighters to quickly break through building doors and windows during emergency rescues. In the event of disasters such as fires and earthquakes, users can use these devices to break glass doors and windows in time, thereby quickly escaping the disaster scene and protecting the lives of residents.
[0003] However, existing door and window breaking devices for fire fighting and rescue often require users to manually pull the breaking cone, which requires considerable force and increases the difficulty of using the device. Furthermore, the breaking cone may not be directly aligned with the glass door or window during release, resulting in a dispersion of the breaking force and reducing the breaking efficiency.
[0004] Therefore, those skilled in the art have provided a door and window breaking device for fire fighting and rescue to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a door and window breaking device for fire fighting and rescue. The device uses a U-shaped rod with a guide rod in conjunction with a suction cup to directly release a breaking cone, thereby ensuring that the breaking cone is directly facing the door or window and preventing the force of the breaking cone from being dispersed, thus improving the breaking efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A door and window breaking device for fire fighting and rescue includes a mounting box. Suction cups are fixedly connected to the lower ends of the four outer walls of the mounting box. Limiting grooves are respectively opened in the middle of the two outer walls of the mounting box. Telescopic rods are fixedly connected to the middle of the inner rear wall of the limiting grooves. Limiting blocks are slidably connected inside the limiting grooves. The outer rear wall of the limiting blocks is fixedly connected to the telescopic end of the telescopic rod. A return spring is fixedly connected to the middle of the outer rear wall of the limiting blocks. A U-shaped rod is fixedly connected to the middle of the outer front wall of the limiting blocks.
[0008] The upper part of the installation box has a first sliding groove, the middle part of the installation box has a second sliding groove, and the lower part of the installation box has a third sliding groove. A threaded rod is rotatably connected to the middle of the bottom surface of the first sliding groove. A positioning plate is threaded to the middle of the outer wall of the threaded rod. A hook is fixedly connected to the rear end of the lower surface of the first positioning plate. A second positioning plate is slidably connected inside the third sliding groove. A hook is fixedly connected to the center of the upper surface of the second positioning plate. A return spring is fixedly connected to the edge of the upper surface of the second positioning plate. A crushing cone is fixedly connected to the middle of the lower surface of the second positioning plate.
[0009] Through the above technical solution, by using a threaded rod with a rotating handle, a first positioning plate with a first hook, a second positioning plate with a second hook, and a second return spring in combination, the user does not need to manually pull the breaking cone, thereby reducing the difficulty of using the door and window breaking device for fire fighting and rescue.
[0010] Furthermore, the first hook and the second hook are tightly fitted together, and both the first hook and the second hook are made of carbon fiber composite material;
[0011] The above technical solution enables the No. 1 hook and the No. 2 hook to have overall rigidity while allowing their ends to be bent.
[0012] Furthermore, the lower end of the crushing cone penetrates through the No. 3 slide groove and extends to the outside of the mounting box;
[0013] The above technical solution facilitates the crushing cone to be housed inside the No. 3 slide groove, thereby enabling the crushing cone to compress the No. 2 return spring and accumulate more elastic potential energy.
[0014] Furthermore, the upper end of the second return spring is fixedly connected to the top surface inside the third slide groove, and the second return spring is sleeved on the outside of the second hook.
[0015] Through the above technical solution, the second hook, under the traction of the first hook, compresses the second positioning plate and the second return spring, thereby facilitating the accumulation of elastic potential energy in the second return spring. This allows the second positioning plate to be directly acted upon when the first hook releases the second hook.
[0016] Furthermore, the lower end of the first hook passes through the first slide groove and extends into the interior of the second slide groove, and the upper end of the second hook passes through the third slide groove and extends into the interior of the second slide groove.
[0017] The above technical solution allows the lower end of hook number one to contact hook number two and bend, thereby making hook number two and hook number one fit together and thus forming a mutual force.
[0018] Furthermore, a guide rod is fixedly connected to the middle of the outer wall of the rear end of the U-shaped rod, and the rear end of the guide rod passes through the mounting box and extends into the interior of the second slide groove;
[0019] The above technical solution allows users to press the U-shaped rod, which in turn causes the limiting block to slide inside the limiting groove, thereby compressing the telescopic rod fitted with the first return spring. This causes the guide rod to contact the first hook, and the head of the first hook to bend, thus releasing the second hook and releasing the elastic potential energy accumulated in the second return spring.
[0020] Furthermore, the upper end of the threaded rod passes through the first sliding groove to the outside of the mounting box and is fixedly connected to a rotating handle;
[0021] The above technical solution allows the threaded rod to be rotated by the handle, which in turn causes the No. 1 positioning disc to slide inside the No. 1 slide groove. This causes the No. 1 slide groove to move the No. 1 hook, eliminating the need for the user to manually pull the crushing cone and thus reducing the difficulty of using the device.
[0022] Furthermore, the rear ends of the first reset springs are respectively fixedly connected to the inner wall of the rear end of the limiting groove, and the first reset springs are respectively sleeved on the outside of the telescopic rod.
[0023] This utility model has the following beneficial effects:
[0024] 1. The present invention proposes a door and window breaking device for fire fighting and rescue, which, through the coordinated use of a threaded rod with a handle, a first positioning plate with a first hook, a second positioning plate with a second hook, and a second return spring, eliminates the need for the user to manually pull the breaking cone, thereby reducing the difficulty of using the door and window breaking device for fire fighting and rescue.
[0025] 2. The fire-fighting and rescue door and window breaking device proposed in this utility model uses a U-shaped rod with a guide rod in conjunction with a suction cup to directly release the breaking cone, thereby making the breaking cone face the door or window, preventing the force of the breaking cone from being dispersed, and thus improving the breaking efficiency.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Reference Figure 2-5 The present invention provides a specific embodiment of a door and window breaking device for fire fighting and rescue, comprising a mounting box 1, suction cups 2 fixedly connected to the lower ends of the four outer walls of the mounting box 1, limiting grooves 3 respectively opened in the middle of the two outer walls of the mounting box 1, telescopic rods 4 fixedly connected to the middle of the inner wall of the rear end of the limiting grooves 3, limiting blocks 6 slidably connected inside the limiting grooves 3, the outer wall of the rear end of the limiting blocks 6 fixedly connected to the telescopic end of the telescopic rods 4, a first-order return spring 5 fixedly connected to the middle of the outer wall of the rear end of the limiting blocks 6, and a U-shaped rod 7 fixedly connected to the middle of the outer wall of the front end of the limiting blocks 6.
[0035] The upper part of the installation box 1 has a first sliding groove 9, the middle part of the installation box 1 has a second sliding groove 14, and the lower part of the installation box 1 has a third sliding groove 15. The middle of the bottom surface of the first sliding groove 9 is rotatably connected to a threaded rod 10. The middle of the outer wall of the threaded rod 10 is threadedly connected to a first positioning plate 12. The rear end of the lower surface of the first positioning plate 12 is fixedly connected to a first hook 13. The inside of the third sliding groove 15 is slidably connected to a second positioning plate 16. The center of the upper surface of the second positioning plate 16 is fixedly connected to a second hook 18. The edge of the upper surface of the second positioning plate 16 is fixedly connected to a second return spring 19. The middle of the lower surface of the second positioning plate 16 is fixedly connected to a crushing cone 17.
[0036] Reference Figure 1-3 Hook 13 and hook 18 fit tightly together. Both hook 13 and hook 18 are made of carbon fiber composite material, which gives them overall rigidity while allowing their ends to bend. The lower end of the crushing cone 17 passes through the third slide groove 15 and extends to the outside of the mounting box 1, facilitating the storage of the crushing cone 17 inside the third slide groove 15. This allows the crushing cone 17 to compress the second return spring 19, accumulating more elastic potential energy. The upper end of the second return spring 19 is fixedly connected to the top surface inside the third slide groove 15. The return spring 19 is sleeved on the outside of the second hook 18. Under the traction of the first hook 13, the second positioning plate 16 compresses the second return spring 19 via the second hook 18. This allows the second return spring 19 to accumulate elastic potential energy, so that when the first hook 13 releases the second hook 18, it can directly act on the second positioning plate 16. The lower end of the first hook 13 passes through the first slide groove 9 and extends into the interior of the second slide groove 14. The upper end of the second hook 18 passes through the third slide groove 15 and extends into the interior of the second slide groove 14, facilitating the passage of the lower end of the first hook 13... The second hook 18 contacts and bends, causing it to engage with the hook surface of the first hook 13, creating a mutual force. A guide rod 8 is fixedly connected to the middle of the outer wall of the rear end of the U-shaped rod 7. The rear end of the guide rod 8 passes through the mounting box 1 and extends into the interior of the second slide groove 14, facilitating the user to press the U-shaped rod 7. This causes the limiting block 6 to slide within the limiting groove 3, compressing the telescopic rod 4, which is fitted with the first return spring 5. This causes the guide rod 8 to contact the first hook 13, bending the head of the first hook 13 and releasing the second hook 18, thus releasing... The elastic potential energy accumulated by the second return spring 19 is released. The upper end of the threaded rod 10 passes through the first slide groove 9 to the outside of the mounting box 1 and is fixedly connected to the handle 11. By rotating the threaded rod 10 through the handle 11, the first positioning plate 12 slides inside the first slide groove 9, thereby causing the first slide groove 9 to drive the first hook 13 to move. This eliminates the need for the user to manually pull the crushing cone 17, thus reducing the difficulty of using the device. The rear ends of the first return spring 5 are fixedly connected to the inner wall of the rear end of the limiting groove 3, and the first return spring 5 is respectively sleeved on the outside of the telescopic rod 4.
[0037] Working principle: When using this fire-fighting and rescue door and window breaking device, firstly, by rotating the threaded rod 10 through the handle 11, the first positioning plate 12 slides inside the first slide groove 9, causing the first slide groove 9 to move the first hook 13 downwards, so that the lower end of the first hook 13 contacts the second hook 18 and bends, thereby making the hook surface of the second hook 18 fit with the hook surface of the first hook 13. Secondly, by rotating the threaded rod 10 through the handle 11, the first positioning plate 12 slides inside the first slide groove 9, causing the first slide groove 9 to move the first hook 13 upwards, and the second hook 18, under the traction of the first hook 13, compresses the second positioning plate 16. The second return spring 19 is used to facilitate the accumulation of elastic potential energy. Then, the suction cup 2 is used to attach the fire-fighting and rescue door and window breaking device to the glass door and window that needs to be broken. Next, by pressing the U-shaped rod 7, the limiting block 6 slides inside the limiting groove 3, thereby compressing the telescopic rod 4 on which the first return spring 5 is sleeved, so that the guide rod 8 contacts the first hook 13 and the head of the first hook 13 bends, thereby releasing the second hook 18, thereby releasing the elastic potential energy accumulated by the second return spring 19. Finally, the second return spring 19 acts directly on the second positioning plate 16, so that the breaking cone 17 acts on the glass door and window and breaks the glass door and window.
[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
