Description

Technical Field

[0001] This utility model relates to the field of window breakers, specifically a new type of window breaker. Background Technology

[0002] In modern transportation and building environments, emergency escape situations occur frequently. For example, in serious accidents such as vehicle collisions, submersion in water, or fires, quickly breaking windows to escape is a crucial step in ensuring the safety of occupants. Traditional window-breaking tools primarily consist of safety hammers; however, safety hammers have several limitations. Firstly, using a safety hammer requires a certain amount of strength and skill, which may be ineffective for the elderly, children, or those with weakened constitutions in emergency situations. Furthermore, the striking point and angle of the safety hammer greatly affect the window-breaking success; improper operation may prevent successful window breaking. Secondly, safety hammers have a single function, only suitable for breaking windows. In actual accident scenarios, it may also be necessary to cut restraints such as seat belts, a requirement that traditional safety hammers cannot meet.

[0003] In building-related situations, such as fires, trapped individuals may need to break windows to escape, but existing window-breaking methods are often not convenient or efficient enough. Furthermore, in some rescue operations, rescuers also need to quickly break windows to enter the trapped area, and existing window-breaking tools are insufficient in terms of efficiency and versatility. Additionally, some existing window-breaking devices are poorly designed, with breaking components prone to accidental triggering when not in use, which could not only damage the equipment but also injure the user. Moreover, the reliability and efficiency of traditional window-breaking tools need improvement when dealing with glass of varying thicknesses and strengths, failing to ensure the rapid and effective breaking of glass barriers in emergencies, thus failing to buy valuable time for escape and rescue. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems by providing a novel window breaker. The window breaker has important applications in emergency escape and rescue scenarios and can be used in various places where there may be trapped people, such as vehicles, ships, and buildings, to help trapped people quickly break through obstacles such as car windows and glass doors to escape. At the same time, its cutting function can also be used to deal with items that hinder escape, such as seat belts and ropes.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a novel window breaker, comprising a tube body, wherein a window breaker component is provided at one end of the tube body and a cutting component is provided at the other end;

[0006] The cutting assembly includes a connecting block, a telescopic spring, a limiting plate, a button, and a cutting head. The connecting block is fixedly installed inside the tube body. The limiting plate is rotatably connected to the connecting block, and its upper end is rotatably connected to the button. One end of the connecting block is connected to the cutting head through the telescopic spring.

[0007] The window-breaking assembly includes a striker, a pressing element, an outer spring, and an inner spring, all disposed inside the tube. The striker is disposed inside the pressing element. The outer spring is disposed inside the tube and is used to control the resetting of the pressing element. The striker is installed inside the inner spring, which is also disposed inside the outer spring to control the ejection of the striker.

[0008] Furthermore, the cutting head includes a cutting head seat and a cutting blade, the cutting head seat is provided with an opening groove, and the cutting blade is disposed in the opening groove;

[0009] The telescopic spring is fixedly connected to a connecting block at one end and to a cutter head seat at the other end.

[0010] Furthermore, the diameter of the connecting block is smaller than the inner diameter of the tube, and the limiting piece is an arc-shaped structure located in the gap between the tube and the connecting block;

[0011] One end of the connecting block is provided with a protrusion, and the circumference of the cutter head seat is provided with an annular groove that matches the protrusion.

[0012] Furthermore, when the protrusion is located in the annular groove, the telescopic spring is compressed, and the entire cutter head is completely located in the tube body;

[0013] The protrusion separates from the annular groove, the telescopic spring returns to its original position, and the cutter head is located outside the tube body.

[0014] In addition, the novel window breaker proposed above according to this utility model may also have the following additional technical features:

[0015] The firing pin includes a needle tip, a limiting shaft, and a rod, wherein the limiting shaft is perpendicular to the rod.

[0016] Furthermore, the tube body is provided with a first guide groove, the pressing member is provided with a second guide groove, the opening of the first guide groove faces upward, the opening of the second guide groove faces downward, and the two ends of the limiting shaft extend to the outside of the second guide groove.

[0017] Furthermore, the second guide groove includes a first vertical groove, an inclined groove, and a second vertical groove connected in sequence.

[0018] Furthermore, when the pressing element is located in the tube body, the first guide groove and the second guide groove partially overlap.

[0019] The advantages of this utility model compared with the prior art are as follows:

[0020] 1. Multifunctionality

[0021] This new type of window breaker integrates both window breaking and cutting functions, offering significant advantages over traditional single-function window breaking tools. In emergency escape or rescue scenarios, whether it's cutting seat belts, ropes, or other restraints, or breaking car windows, glass doors, or other obstacles, this single tool can accomplish the task. This versatility greatly enhances the ability to respond to complex and dangerous situations, reduces the inconvenience of carrying multiple tools, and provides greater convenience for escape and rescue operations.

[0022] 2. Ease of operation

[0023] Regarding the cutting function, the blade 1025 can be ejected simply by pressing button 1024, making operation simple and intuitive, requiring no special training or skills. For the window-breaking function, simply press the pressing element 1012 against the glass and press the tube 1 to break the window; this requires minimal strength from the user, and ordinary personnel can easily operate it in an emergency. This convenient operation method can save valuable time in emergencies and improve the success rate of escape and rescue.

[0024] 3. Compact structure

[0025] The entire window breaker features a compact and rational structural design. Both the window-breaking component 101 and the cutting component 102 are cleverly housed within the tube body 1, without taking up excessive space. This compact design makes the window breaker easy to carry and can be easily placed in a vehicle's glove compartment, a building's emergency escape kit, or a personal emergency kit. Furthermore, the compact structure allows for more flexible operation during use, without compromising ease of use due to excessive size.

[0026] 4. Security

[0027] In the non-use state, the blade 1025 is reliably fixed inside the tube 1 by the engagement of the protrusion 10231 on the limiting plate 1023 with the annular groove 10254 of the blade holder 10251, and the compressed state of the telescopic spring 1022, effectively preventing the blade 1025 from accidentally popping out and injuring people. For the window breaker assembly 101, its internal spring and guide groove design ensures that the firing pin 1011 will not pop out accidentally under normal circumstances; the window breaker function will only be triggered under correct operation. This safety design improves the safety of the window breaker during carrying and storage, reducing safety accidents caused by misoperation or accidental triggering.

[0028] 5. Highly efficient window breaking

[0029] The coordinated design of the inner spring 1014 and outer spring 1013 in the window breaking assembly 101 is key to achieving efficient window breaking. During the window breaking operation, the inner spring 1014 can accumulate sufficient energy during compression. When the window breaking condition is triggered, the inner spring 1014 quickly returns to its original position, ejecting the striking pin 1011 with considerable force. Upon ejection, the striking pin rotates due to the structure of the second guide groove, improving the window breaking efficiency. This design effectively improves the efficiency and success rate of window breaking, even for thicker or stronger glass, allowing for rapid penetration and buying more time for escape and rescue.

[0035] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] I. Working principle of this utility model:

[0037] 1.1 This novel window breaker mainly includes a tube body 1, with a window breaking component 101 at one end and a cutting component 102 at the other end. This design integrates window breaking and cutting functions into one tool, making it convenient to use.

[0038] 1.2 Cutting component 102

[0039] Connecting block 1021: Connecting block 1021 is fixedly installed inside the tube body 1, serving as an important support component of the cutting assembly. It is made of a high-strength, corrosion-resistant metal, such as stainless steel. The shape of connecting block 1021 is designed as a cylinder that matches the internal contour of the tube body 1, with a diameter smaller than the internal diameter of the tube body 1, ensuring stable installation within the tube body 1 without affecting the movement of other components. Connecting block 1021 has a dedicated structure for mounting the telescopic spring 1022, ensuring the spring is securely installed and can extend and retract normally. Simultaneously, connecting block 1021 also has a rotating connection structure that cooperates with the limiting plate 1023, ensuring that the limiting plate 1023 can rotate flexibly around it.

[0040] Telescopic spring 1022: The telescopic spring 1022 is made of high-quality, high-elasticity alloy material, possessing excellent elasticity and fatigue resistance. One end of the spring is fixedly connected to the connecting block 1021, and the other end is fixedly connected to the cutter head holder 10251. Its elastic coefficient is carefully designed so that it is in a compressed state under normal conditions, storing a certain amount of elastic potential energy. When the restriction is released, it can provide sufficient power for the ejection of the cutter head 1025.

[0041] Limiting plate 1023: The limiting plate 1023 has an arc-shaped structure and is located in the gap between the tube body 1 and the connecting block 1021. It is made of a metal material with certain strength and toughness, ensuring it will not deform during repeated use. One end of the limiting plate 1023 is rotatably connected to the connecting block 1021, allowing it to rotate flexibly within a certain range. The upper end of the limiting plate 1023 is rotatably connected to the button 1024. When the button 1024 is pressed, its movement is transmitted to the limiting plate 1023, causing it to rotate. One end of the limiting plate 1023 has a protrusion 10231, which engages with the annular groove 10254 on the cutter head seat 10251 to control the extension and retraction of the cutter head 1025.

[0042] Button 1024: Button 1024 is made of ergonomically designed plastic material with a non-slip textured surface for easy user operation. The internal structure of button 1024 and its connection to the limiting plate 1023 are cleverly designed to accurately transmit pressing pressure to the limiting plate 1023, allowing it to rotate smoothly. The position of button 1024 on the tube body 1 is reasonable, facilitating user operation without affecting the overall appearance and other functions of the window breaker.

[0043] Blade 1025:

[0044] Cutter head holder 10251: The cutter head holder 10251 is circular and made of high-strength metal material. An opening slot 10253 is provided on the cutter head holder 10251. The shape and size of the opening slot 10253 match the blade 10252 for mounting the blade 10252. A circumferential groove 10254 is provided on the cutter head holder 10251. The circumferential groove 10254 cooperates with a protrusion 10231 on the limiting plate 1023 to achieve extension and retraction control of the cutter head 1025. When the protrusion 10231 is located in the circumferential groove 10254, the cutter head 1025 is confined within the tube body 1; when the protrusion 10231 separates from the circumferential groove 10254, the cutter head 1025 is ejected from the tube body 1 under the action of the extension spring 1022.

[0045] Blade 10252: Blade 10252 is made of high-hardness, high-sharpness alloy steel, such as high-speed steel. The shape and size of blade 10252 are designed according to the cutting function requirements, and are usually slender. The cutting edge is finely ground to ensure high efficiency when cutting ropes, safety belts, and other items. Blade 10252 is installed in the slot 10253 of the cutter head holder 10251. The installation method is firm and reliable, such as by welding, slot fixing, or other suitable connection methods, to prevent blade 10252 from loosening or falling off during use.

[0046] 1.3 Broken Window Component 101

[0047] Strike pin 1011: Strike pin 1011 comprises a pin tip, a limiting shaft, and a rod, with the limiting shaft perpendicular to the rod. The pin tip is made of a high-hardness hard alloy material, such as tungsten carbide, to ensure easy penetration of the glass surface upon impact. The rod is made of a high-strength metal material to ensure it can withstand significant impact forces without deformation under the action of the spring. The design of the limiting shaft plays a crucial role in guiding and controlling the movement of strike pin 1011 within the tube 1.

[0048] Pressing element 1012: Pressing element 1012 cooperates with tube body 1, and its material is metal or engineering plastic with certain strength and wear resistance. Pressing element 1012 is provided with a second guide groove 10121, which includes a first vertical groove, an inclined groove and a second vertical groove connected in sequence. The position and movement of pressing element 1012 in tube body 1 are restricted by tube body 1 and outer spring 1013. In window breaking operation, pressing element 1012 is used to transmit the external force applied by the user, so that the firing pin 1011 can be ejected at the appropriate time. When the firing pin is ejected, due to the structure of the second guide groove, the firing pin will rotate, improving the window breaking efficiency.

[0049] Outer spring 1013: The outer spring 1013 is located inside the tube body 1, and its function is to control the reset of the pressing element 1012. The outer spring 1013 is made of high-strength spring steel and has a suitable elastic coefficient. It can provide the reset force for the pressing element 1012 after it is pressed, ensuring that the window breaker can return to its initial state after use for the next use.

[0050] Inner spring 1014: The inner spring 1014 is installed outside the firing pin 1011 and inside the outer spring 1013, and is used to control the ejection of the firing pin 1011. The inner spring 1014 also uses high-quality spring material, and its elastic coefficient and stroke have been precisely calculated and designed. During the window-breaking operation, the inner spring 1014 stores energy during compression. When specific conditions are met, its elastic force causes the firing pin 1011 to be ejected suddenly, realizing the window-breaking function. The tube body 1 is provided with a first guide groove 103. The opening of the first guide groove 103 faces upward and cooperates with the second guide groove 10121 on the pressing member 1012, which faces downward. When the pressing member 1012 is located in the tube body 1, the first guide groove 103 and the second guide groove 10121 partially overlap, and the two ends of the limiting shaft extend to the outside of the second guide groove 10121, so that the firing pin 1011 can move along a predetermined trajectory during the movement of the pressing member 1012.

[0051] Implementation

[0052] 2.1 When the cutting function is required;

[0053] The user presses button 1024. Upon pressure, button 1024 rotates the limiting plate 1023 connected to it. Due to the rotation of the limiting plate 1023, the protrusion 10231 on the limiting plate 1023, originally located in the annular groove 10254 of the cutter head seat 10251, separates from the annular groove 10254. At this time, the telescopic spring 1022 is no longer restricted and rapidly extends under the action of its stored elastic potential energy, pushing the cutter head 1025 outwards, causing the cutter head 1025 to quickly pop out of the tube body 1, exposing the blade 10252, thus allowing it to be used to cut ropes, safety belts, and other items. After the cutting operation is completed, the user can manually push the cutter head 1025 back into the tube body 1. During this process, the annular groove 10254 on the cutter head holder 10251 re-engages with the protrusion 10231 on the limiting plate 1023, and the cutter head 1025 is fixed in the tube body 1 again under the state of compression of the telescopic spring 1022, ready for the next use.

[0054] 2.2 When using the broken window feature;

[0055] The user holds the tube body 1 and presses the pressing element 1012 firmly against the glass surface to be broken. The user then applies pressure to the tube body 1, causing the pressing element 1012 to move inwards. During this downward movement, the second guide groove 10121 on the pressing element 1012 interacts with the first guide groove 103 on the tube body 1, causing the limiting shaft on the firing pin 1011 to move within the first and second guide grooves. Simultaneously, the outer spring 1013 and the inner spring 1014 are compressed synchronously by the pressure from the pressing element 1012. When the limiting shaft passes through the inclined groove in the second guide groove 10121 as the pressing element 1012 moves, the inner spring 1014, no longer restricted by the inclined groove, begins to reset. During this reset process, the inner spring 1014 releases the large amount of energy accumulated during compression, propelling the firing pin 1011 outwards. The tip of the striking pin 1011 strikes the glass under strong elastic force, using the sharp shape of the tip and the energy released by the spring to overcome the strength of the glass and break it. When the striking pin pops out, the structure of the second guide groove causes the striking pin to rotate, improving the window breaking efficiency. After breaking the window, the user releases the force of pressing the tube 1, and the elastic force of the outer spring 1013 causes the pressing part 1012 to return to the initial position, and the entire window breaker returns to its unused state.

[0056] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
