[0002] In modern urban transportation systems, buses are one of the main means of public transportation, carrying a large number of daily commuters. Since buses usually operate in crowded urban environments and carry a large number of passengers, ensuring the safety of passengers has become a top priority in bus operations. In emergency situations, such as fires, traffic accidents, or other situations that require emergency evacuation, the tempered glass windows on buses become a potential obstacle for passengers to escape. At these critical moments, breaking the tempered glass quickly and effectively becomes a key factor in the success of the rescue operation.

[0003] However, existing window-breaking tools often have problems such as insufficient power, complicated operation, or unnecessary damage to the glass, which limits the efficiency of window-breaking and increases the risk of rescue operations. In addition, the installation and use methods of some window breakers are not intuitive enough, which increases the difficulty of operation for users in emergency situations and may delay rescue time. Therefore, developing an adjustable emergency window breaker suitable for buses and providing an installation method to ensure its normal function are of great significance to improving the safety of buses and the efficiency of emergency rescue.

[0004] The present invention provides an installation and use method of an adjustable emergency window breaker on a bus, which is intended to ensure that the window breaker can be quickly and effectively activated in an emergency to break the tempered glass and provide an escape route for passengers. The correct installation method can not only ensure that the performance of the window breaker is fully utilized, but also minimize the potential risks to the user and the surrounding environment. Providing a correct installation and use method is of great significance for improving self-rescue and mutual rescue capabilities in emergency situations. Through its innovative design and providing a correct use method, the present invention will provide a more reliable and effective solution for modern emergency rescue, thereby significantly improving the safety and rescue efficiency of buses in emergency situations. Summary of the invention

[0005] The present invention aims to solve the problems existing in the installation and use of existing window breakers, and provides an installation and use method of an adjustable bus-mounted emergency window breaker, aiming to ensure that the window breaker can reach and play the best window breaking state. The core of the present invention is that through precise installation and simple operation, the window breaker can be quickly and effectively activated in an emergency to break the tempered glass and provide an escape route for passengers.

[0006] The installation method of the present invention provides a set of standardized installation processes, ensuring that the fixed position of the window breaker on the vehicle is easy for passengers to quickly locate and can maintain consistent operating logic in different vehicle models and glass configurations.

[0007] The use method of the present invention avoids the problems of improper force adjustment and improper use. According to the use method, the user can easily adjust the force of the window breaker for tempered glass of different thicknesses, ensuring that the most effective window breaking effect can be achieved with the minimum force in an emergency, thereby ensuring that the user can correctly use the window breaker in a tense emergency situation.

[0008] The object of the present invention is achieved in this way: an installation and use method of an adjustable bus-mounted emergency window breaker, the window breaker includes a main rod, an energy storage releaser, a pressing rod, a slider, a large suction cup, a positioning rod head, a rotating sleeve head, and a pressure regulating head; one end of the main rod is provided with a barbed hook, and the other end is provided with a fork head; the first rotating shaft enables the main rod and the rotating sleeve head to be rotationally connected; the second rotating shaft enables the main rod and the pressing rod to be rotationally connected; the energy storage releaser is fixed to the part of the main rod near the fork head, and the lower end of the energy storage releaser is provided with a pressing energy storage head, which is used to push the inner cavity The firing pin arranged in the middle drives the energy storage spring mounted on the firing pin to store energy; a slideway and an internal thread are arranged at the top of the energy storage releaser; a limit block is arranged in the slideway; the top of the energy storage spring is pressed against the bottom surface of the limit block; the external thread can be screwed into the internal thread; the compression amount of the energy storage spring can be adjusted by rotating the pressure regulating head, and the force of breaking the window can be adjusted; the user can easily make the energy storage releaser complete the whole process of energy storage and energy release by pulling and pressing the tail rod, and the various components on the window breaker cooperate with each other, and the whole process of energy storage and energy release can be repeated many times until the purpose of breaking the window is achieved; A large suction cup cavity is arranged in the middle of the large suction cup; a groove is arranged in the large suction cup cavity, and an air hole is arranged in the middle of the groove; a small suction cup pull rod is arranged on the back of the small suction cup, and the small suction cup pull rod is inserted into the air hole; the pull rod is thick at the bottom and thin at the top, and the shape and size of the connection with the small suction cup match the air hole; after the lower end of the pull rod blocks the air hole, air cannot enter and exit from the air hole, so that the window breaker can be adsorbed on the glass window for a long time to prevent the window breaker from swinging arbitrarily; it is characterized in that: the steps of the installation and use method of the window breaker with adjustable storage capacity include: 1. Installation Preparation: Confirm the thickness and planar dimensions of the tempered glass used in the vehicle windows where the window breaker is to be installed; Cut, grind and drill a round hole for installing the window breaker on the untempered glass. The top of the round hole should be about 20mm away from the frame of the future fixed tempered glass, and the left and right sides of the round hole should be more than 150mm away from the frame of the future fixed tempered glass. The diameter of the round hole should be 2mm larger than the diameter of the positioning rod. The glass is tempered by professional manufacturers; When fixing the tempered glass, make sure that the edge of the tempered glass closest to the round hole is facing upwards, and then fix the tempered glass in the predetermined position; Adjust the compression of the energy storage spring Rotate the voltage regulating head clockwise to make the limit block contact the energy storage spring downward until the limit block contacts the energy storage spring and it is difficult to continue rotating the voltage regulating head; Place the energy storage head on a wooden board, hold and press the energy storage releaser with your hand and press hard, so that the energy storage head squeezes the energy storage spring in the energy storage releaser to store energy, until the energy storage head suddenly loses control of the energy storage spring under the action of the protruding structure of the inner cavity, and the energy storage spring instantly releases energy to push the impact needle to hit the object below, and test whether the energy storage head has restored control of the energy storage spring when repeating this action; If the above test finds that the energy storage head does not quickly restore control over the energy storage spring, it is necessary to rotate the voltage regulating head counterclockwise to restore the energy storage head to control the energy storage spring; Install the window breaker on tempered glass Hold the main rod, separate the positioning rod installed in the rotating sleeve from the second positioning rod head and remove a washer; Confirm the side of the tempered glass where the window breaker is installed, insert the positioning rod into the preset through hole on the tempered glass from the side where the window breaker is installed, and then install the gasket. Confirm that the gasket in contact with the tempered glass is made of non-metallic material to avoid chemical reaction with the glass or damage; Fix the second positioning rod head and the positioning rod together, and fix the window breaker on the tempered glass; Confirm that the rotating sleeve can rotate along the axis of the positioning rod, but will not fall off the rotating sleeve, and the parts connected to the rotating sleeve will droop naturally; 2. Use Secure in a safe state Hold the tail rod and push the slider toward the ring to separate the barbed hook from the limiting protrusion; Push the tail rod toward the tempered glass, press the large suction cup onto the tempered glass to exhaust the air under the large suction cup, so that it can be adsorbed on the tempered glass; Make sure that the shaking of the tempered glass will not cause the large suction cup to fall off the tempered glass immediately when the vehicle is driving; As time goes by, the large suction cup separates from the tempered glass due to the entry of air. When the vehicle is moving again and the tempered glass window shakes, the tail rod will shake synchronously and drive the large suction cup to touch the tempered glass. The large suction cup can automatically complete another process of exhausting, adsorbing, and fixing on the tempered glass. Breaking windows in an emergency Hold the ring at the end of the tail rod and pull it away from the tempered glass. At this time, the large suction cup under the tail rod is deformed by force. Since the small suction cup is still attached to the tempered glass, a gap will appear between the small suction cup pull rod and the air hole on the large suction cup. Gas will flow into the large suction cup, and the large suction cup will quickly separate from the tempered glass. Continue to pull the grip ring away from the tempered glass until the limit convex head is placed above the barbed hook; Hold the hand and press the ring toward the tempered glass, forcing the energy storage head to squeeze the energy storage spring in the energy storage releaser to store energy, until the energy storage head suddenly loses control of the energy storage spring under the action of the protruding structure of the inner cavity, and the energy storage spring instantly releases energy to push the impact needle to hit the tempered glass and break the window; If the window cannot be broken, repeat the above steps until the window is broken successfully.

[0009] Preferred solution one, as a preferred solution of the basic solution, a limiting protrusion is provided on the rotating sleeve head, and the protrusion limits the upward rotation angle of the main rod so that the pressing energy storage head will not leave the glass surface, thereby ensuring efficient window breaking efficiency.

[0010] Preferred solution two, as a preferred solution of preferred solution one, after the rotating head is fixed, the rotating sleeve head can still rotate along the axis of the positioning rod, but will not fall off the rotating head. When the large suction cup is not adsorbed on the tempered glass, the window breaker will naturally droop and the ring will be below the main rod.

[0011] Preferred solution three, as a preferred solution of preferred solution two, when the limiting protrusion is placed under the inverted hook, the pressing rod can swing between the inverted hook and the tempered glass, the large suction cup can prevent the tail rod from directly colliding with the tempered glass, and can use negative pressure to adsorb on the tempered glass when it contacts the tempered glass.

[0012] Preferred solution four, as a preferred solution of preferred solution three, a small L groove and a large L groove are provided on both sides of the pressing rod; a tension spring and a positioning rod head are provided on it; the two ends of the tension spring are respectively fixed on the positioning rod head and the thumbtack; under the action of the tension spring, the slider always moves forward until it is blocked by the lateral end of the small L groove or the large L groove.

[0013] Preferred solution five, as a preferred solution of preferred solution four, under the action of the limiting protrusion, the external force can make the pressing rod rotate upward along the axis of the second rotating shaft over the inverted hook, but cannot make the pressing rod rotate downward over the inverted hook.

[0014] Preferred solution six, as a preferred solution of preferred solution five, the large suction cup is made of latex, and pulling the tail rod will cause the large suction cup to deform, resulting in a gap between the pull rod and the air hole.

[0015] The technical solution of the present invention has the following beneficial effects: 1) Adjustable energy storage strength: By adjusting the compression of the energy storage spring through the pressure regulating head, the elastic force of the striker can be changed to adapt to tempered glass of different thicknesses, thereby improving the applicability and flexibility of the window breaker.

[0016] 2) Stable structure: The rotating connection design between the main rod, the rotating sleeve and the pressing rod ensures the stability and reliability of the window breaker during use.

[0017] 3) Easy operation: Users can destroy the surface stress of tempered glass through simple operations to achieve the purpose of quick window breaking without complicated operating steps.

[0018] 4) Prevent direct collision: The design of the large suction cup can prevent the tail rod from directly colliding with the tempered glass, reducing damage to the window breaker and the glass.

[0019] 5) Rapid adsorption and separation: The large suction cup uses negative pressure to adsorb on the tempered glass, and by pulling the tail rod to deform, a gap will appear between the rod and the pore, so that it can be quickly separated from the glass.

[0020] 6) High safety: By setting the barbed hook and the limiting convex head, the rotation direction of the pressing rod is limited, which prevents unexpected use and improves the safety of use.

[0021] 7) Easy maintenance: The modular design of each component makes the maintenance and replacement of the window breaker simple, extending the service life of the product.

[0022] 8) Strong adaptability: Due to the use of adjustable energy storage design and suction cup design, the window breaker of the present invention can adapt to tempered glass of different thicknesses and types, thereby increasing its application range.

[0023] By adopting the installation and use method of the present invention, even in extremely urgent and dangerous environments, the user can quickly and accurately use the window breaker, thereby minimizing injuries and losses and increasing the chances of survival and rescue.
