Description

Technical Field

[0001] This utility model relates to the field of window breaker technology, specifically a spring-loaded window breaker. Background Technology

[0002] A spring-loaded window breaker is a tool used to break windows for escape in emergencies. It mainly consists of a spring mechanism and a firing pin. Its working principle is that pressing or triggering the spring stores energy, which is then released instantaneously, pushing the firing pin to strike the car window with powerful impact. This concentrated force breaks the glass, creating an escape route for occupants in emergencies such as fire or drowning. Spring-loaded window breakers are characterized by their simple operation, high efficiency, compact size, and ease of portability and installation, making them an important emergency device for ensuring the safety of vehicle occupants.

[0003] Patent publication number CN210331407U discloses a push-type spring window breaker. In the outer shell, a button, a main spring, a hammer, a return spring, and a hammer tip are arranged sequentially from top to bottom. The button and the hammer are provided with guide slopes in the same direction. The button can only move longitudinally along the outer shell. The hammer is provided with a locking pin that penetrates the radial direction of the hammer. The two ends of the locking pin are embedded in the locking grooves provided in the inner wall of the outer shell.

[0004] To address the issue that water resistance significantly limits the speed at which a person can swing a safety hammer in an underwater environment, making it more difficult to break car windows, existing technology involves pressing a button on the glass with the hammer tip to break the window. However, this method lacks protective devices to prevent the glass shards from falling, which can easily cause injury. Therefore, we propose a spring-loaded window breaker. Utility Model Content

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 A spring-loaded window breaker includes a housing 1, one end of which is provided with a magnetic suction mechanism 2 for protection;

[0025] The magnetic attraction mechanism 2 includes a protective plate 21. A sliding groove is provided at one end of the housing 1, and the protective plate 21 slides in the sliding groove. A magnetic plate 22 is fixedly connected to the inner end of the protective plate 21. There are four magnetic plates 22, four first strong magnets 23 and four second strong magnets 24. When the four magnetic plates 22 attract each other, the ejector pin 7 is prevented from being exposed due to accidental contact, and the ejector pin 7 is effectively blocked to prevent it from causing damage to the outside world. The surface of the magnetic plate 22 is fixedly connected to the first strong magnet 23. A crescent groove is provided at the sliding groove of the protective plate 21, and the second strong magnet 24 is fixedly connected in the crescent groove. The upper surface of the first strong magnet 23 is movably connected to the lower surface of the second strong magnet 24. When the first strong magnet 23 and the second strong magnet 24 attract each other, the protective plate 21 can be expanded outward to block the glass shards that fly after breakage and reduce the risk of injury to the user.

[0026] Please see Figures 1-6 The upper surface of the housing 1 is provided with a snap-fit ​​mechanism 3, which includes a snap-fit ​​box 31. The lower surface of the snap-fit ​​box 31 is fixedly connected to the upper surface of the housing 1. Snap-fit ​​holes 32 are provided on both sides of the snap-fit ​​box 31. A sliding block 33 is slidably connected to the inner surface of the snap-fit ​​box 31. An anti-slip block 35 is fixedly connected to the upper surface of the sliding block 33. A cutting blade 34 is fixedly connected to the outer end of the sliding block 33. The cutting blade 34 is used to cut car seat belts. The sliding block 33 is a hollow design. A pressing spring 36 is provided inside the cavity of the sliding block 33. One end of the pressing spring 36 is fixedly connected to the inner cavity of the sliding block 33. The other end of the pressing spring 36 is fixedly connected to a pressing block 37. The surface of the pressing block 37 is movably snapped into the snap-fit ​​hole 32. By pressing the pressing block 37, the sliding anti-slip block 35 snaps the pressing block 37 into the snap-fit ​​hole 32 at the outer end, exposing the cutting blade 34 for use.

[0027] Please see Figures 1-6 Anti-slip strips 4 are fixedly connected to both sides of the housing 1 to enhance the friction between the device and the user's hand. Slide grooves 5 are provided on the upper and lower surfaces of the inner cavity of the housing 1, and sliding parts 6 are slidably connected to the surface of the slide grooves 5.

[0028] Please see Figures 1-6 A fixing block 9 is fixedly connected to the inner surface of the housing 1. A through hole is opened on the surface of the fixing block 9. A ejector pin 7 is slidably connected to the through hole. A sliding member 6 is fixedly sleeved on the surface of the ejector pin 7. A strong spring 8 is provided between the sliding member 6 and the fixing block 9. The inner ring of the strong spring 8 is slidably sleeved on the ejector pin 7. The ejector pin 7 is driven to be ejected and exposed by the rebound force of the strong spring 8.

[0029] Please see Figures 1-6The other end of the housing 1 is provided with a snap-fit ​​groove 11. A snap-fit ​​plate 10 is movably snapped onto the surface of the snap-fit ​​groove 11. A torsion block 12 is fixedly connected to the side of the snap-fit ​​plate 10 away from the fixing block 9. By rotating the torsion block 12, the limiting of the snap-fit ​​plate 10 is removed, causing the strong spring 8 to rebound. The side of the snap-fit ​​plate 10 near the fixing block 9 is rotatably connected to the tail end of the ejector pin 7.

[0030] The working principle of this spring-loaded window breaker will be explained in detail below.

[0031] like Figures 1-6 As shown, by sliding the protective plate 21, the first strong magnet 23 and the second strong magnet 24 are attracted to each other, exposing the protective plate 21. By pressing the ejector end of the housing 1 against the car window glass, the locking groove 11 is removed from the locking plate 10 by rotating the torsion block 12. Then, the strong spring 8 rebounds and drives the ejector pin 7 to break the car window glass. The protective plate 21 blocks the broken glass. When the cutting knife 34 needs to be used, the pressing block 37 is pressed and the anti-sliding block 35 is slid to engage the pressing block 37 in the locking hole 32 at the outer end, so that the cutting knife 34 can be exposed for use.
