Description

Technical Field

[0001] The present invention belongs to the technical field of fire safety equipment, and more specifically, to a glass breaking device for security and its usage method. Background Art

[0002] A window breaker is a tool used to break car windows or other windows in emergency situations. It is usually equipped with a sharp metal tip for quick entry into a trapped area. It is commonly used in emergency rescue or fire fighting operations. Most of the commonly used window breakers at present are fire hammers, which break the glass by hitting the edge of the glass with a hand-held fire hammer for emergency escape. This tool is inconvenient to use and is severely limited when used underwater.

[0003] To better meet the usage requirements, there appears a small and portable cylindrical window breaker on the market. Only by pressing the head against the glass and pressing down forcefully can the glass be broken. Its principle is to utilize the elastic potential energy generated by a compression spring and then use a firing pin to impact the glass. This window breaker has good usage effect and is convenient to carry, but there are also some problems;

[0004] Firstly, the breaking effect is not ideal for special glasses. Since a conventional spring is used inside, the elastic potential energy stored is not large enough, resulting in insufficient impact force. Secondly, a certain amount of force is required to compress the spring when using it, and some people have less strength and cannot compress the spring inside the device, thus unable to use the device normally. Summary of the Invention

[0021] The present invention provides a method for using a security glass breaking device, which is used to operate the above-mentioned security glass breaking device, comprising the following steps:

[0022] The operator holds the outer cylinder so that the bottom end of the inner cylinder touches the glass;

[0023] The outer cylinder is pressed to move toward the glass. During the movement of the outer cylinder, the volume of the chamber defined by the inner wall of the outer cylinder and the top surface of the middle cylinder decreases. At the same time, the guide member pushes the hydraulic oil filled in the oil chamber into the chamber defined by the inner wall of the outer cylinder and the top surface of the middle cylinder, pushing the middle cylinder to move along the inner cylinder toward the glass. The middle cylinder compresses the elastic energy storage component to store energy. When the middle cylinder moves, the protrusion pushes the resistance ring out of the open groove, and the elastic energy storage component pushes the impact head on the resistance ring to impact and break the glass.

[0024] Compared with the prior art, the present invention has the following beneficial technical effects:

[0025] The present invention proposes a glass breaking device for security use. The Pascal principle is used in this device to cause hydraulic oil to apply pressure to the elastic energy storage component, thereby causing the elastic energy storage component to store energy. After the protrusion in the middle cylinder releases the limit on the resistance ring, the elastic potential energy accumulated in the elastic energy storage component is released, pushing the first striker and the impact head to generate a greater impact force to break the glass, making it more labor-saving for the operator to use and suitable for people with different strengths.

[0026] Furthermore, the elastic energy storage component in the device performs dual energy storage through the thick spring and the return spring, so that the first striker and the impact head generate a huge impact force to hit the glass, reducing the operator's strength requirements and making the operator more labor-saving.

[0027] Furthermore, an impact head is provided in the device to assist in breaking. The outer cylinder compresses the deflection spring and the energy storage spring. After the second striker is straightened by the deflection spring, the elastic potential energy of the energy storage spring is released by the action of the deflection spring, causing the top end of the second striker to collide with the inner wall of the cylindrical groove on the hammer. The impact force generated by the collision is transmitted to the impact head through the deflection seat, and the impact head breaks the glass under the action of the impact force, improving the breaking effect.

[0043] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] The present invention proposes a glass breaking device for security, such as Figures 1 to 9 As shown, it includes an outer cylinder 1, a guide piece is movably connected to the bottom end surface of the outer cylinder 1 along its axial direction, the bottom end of the guide piece is connected to the inner cylinder 3, the inner cylinder 3 is provided with a middle cylinder 2, and the middle cylinder 2 is installed in the outer cylinder 1 near its upper end; an oil chamber 15 is provided in the outer cylinder 1, and the oil chamber 15 is communicated with the chamber surrounded by the inner wall of the outer cylinder 1 and the top surface of the middle cylinder 2; the oil chamber 15 is filled with hydraulic oil 17; the middle cylinder 2 is provided with an elastic energy storage component, and a resistance ring 9 is connected to the bottom end of the elastic energy storage component, and an impact head 12 is provided at the center position of the bottom end surface of the resistance ring 9, and the bottom end surface of the resistance ring 9 is located at the side position of the impact head 12 and is clamped in the open groove 10 opened on the inner cylinder 3, and the impact head 12 in the normal state is limited by the resistance ring 9, and a protrusion 14 is provided on the inner wall of the middle cylinder 2. When the outer cylinder 1 moves along the axial direction of the middle cylinder 2, the hydraulic oil 17 completes the effect on the elastic energy storage component, completing After energy is stored, the protrusion 14 releases the limit of the resistance ring 9, so that the elastic energy storage component pushes the impact head 12 to impact and break the glass. During use, the operator holds the outer cylinder 1, places the bottom end surface of the inner cylinder 3 on the glass to be broken, and applies pressure to the outer cylinder 1, so that the outer cylinder 1 moves toward the glass. Under the action of the guide member, the hydraulic oil 17 filled in the oil chamber 15 is pressurized. The hydraulic oil 15 transmits the pressure to the middle cylinder 2, so that the middle cylinder 2 moves along the axial direction of the inner cylinder 3 toward the glass, compressing the elastic energy storage component and accumulating elastic potential energy. After the movement of the protrusion 14 provided on the inner wall of the middle cylinder 2 pushes the resistance ring 9 out of the open groove 10, the elastic energy storage component releases the accumulated elastic potential energy and pushes the impact head 12, so that the impact head 12 carries a large impact force to impact and break the glass, so that the operator can achieve glass breaking with a smaller thrust, which is more labor-saving and better meets the use requirements.

[0045] like Figures 1 to 4As shown, the elastic energy storage component includes a second fixing plate 7 fixedly installed on the middle cylinder 2. A thick spring 8 is connected to the bottom end face of the second fixing plate 7. The thick spring 8 is obliquely installed in the middle cylinder 2, that is, the top end of the thick spring 8 is fixedly connected to the bottom end face of the second fixing plate 7. One end of the thick spring 8 relative to the inner cylinder 3 is connected to a contact ring 9. When an operator applies a driving force to the outer cylinder 1, the second fixing plate 7 also moves along with the middle cylinder 2 to compress the thick spring 8. Elastic potential energy will be accumulated during the compression of the thick spring 8. When the protrusion 14 releases the limit on the contact ring 9, the elastic potential energy accumulated during the compression of the thick spring 8 will push the contact ring 9 and the impact head 12 to move, so that the impact head 12 quickly impacts the glass.

[0046] As Figures 1 to 4 As shown, the elastic energy storage component further includes a first fixing plate 5 fixedly installed in the middle cylinder 2, and the first fixing plate 5 is located below the second fixing plate 7 for connection and fixing. A through hole is provided at the center of the first fixing plate 5, and a first ejector pin 11 is inserted through the through hole. One end of the first ejector pin 11 is movably connected to the second fixing plate 7, and a thick spring 8 is sleeved outside the first ejector pin 11; one end of the first ejector pin 11 relative to the contact plate 19 is connected to the impact head 12, and a contact ring 9 is installed at a position close to the impact head 12 on the first ejector pin 11; a return spring 6 is provided between the bottom end face of the first fixing plate 5 and the top end face of the inner cylinder 3. The top end of the return spring 6 is fixed to the bottom end face of the first fixing plate 5, and the bottom end of the return spring 6 is on the top end face of the inner cylinder 3. The thick spring 8 and the first ejector pin 11 are inserted through the return spring 6 to further accumulate elastic potential energy, so that the impact head 12 carries a greater impact force during the process of impacting the glass.

[0047] As Figure 4 As shown, the top end of the first ejector pin 11 extends above the second fixing plate 7 and is fixedly connected with a limit ring 13. The limit ring 13 is used to limit the bottom of the first ejector pin 11 to prevent the first ejector pin 11 from detaching from the device and affecting repeated use. The top of the middle cylinder 2 is fixedly connected with a first piston 4.

[0048] As Figure 4As shown in the figure, the guiding member includes two abutting plates 19 arranged at the bottom end of the inner cylinder 3. The two abutting plates 19 are symmetrically arranged about the axis of the inner cylinder 3. A guide rod 18 is connected to the abutting plate 19. The top end of the guide rod 18 is connected to a second piston 16. The second piston 16 is slidably installed at the bottom of the oil cavity 15 and is used to push the hydraulic oil 17 to apply pressure to the elastic energy storage component. And the area of the top end face of the first piston 4 is several times that of the top end face of the second piston 16. According to Pascal's principle, it can be understood that when the first piston 4 applies a pressure to the hydraulic oil 17 in the oil cavity 15, the pressure received by the second piston 16 will be amplified, and the pressure will increase to several times the original, so as to push the middle cylinder 2 to move downward and compress both the return spring 6 and the thick spring 8 to accumulate elastic potential energy, so as to enable the impact head 12 to carry a greater impact force, so that the operator can easily break the glass through this device.

[0049] As Figures 4 to 7 shown, a rotating shaft 20 is rotatably installed at the top of the outer cylinder 1. One end of the rotating shaft 20 extends into the outer cylinder 1, and the other end of the rotating shaft 20 extends outside the outer cylinder 1. A mounting plate 21 is connected to the end of the rotating shaft 20 located inside the outer cylinder 1. A rubber plug 22 is connected to the side of the mounting plate 21. The rubber plug 22 blocks the oil outlet of the oil cavity of the outer cylinder 1; a swing rod 23 is connected to the end of the rotating shaft 20 located outside the outer cylinder 1. A sector-shaped limiting groove 24 is formed on the top end face of the outer cylinder 1. The included angle of the sector-shaped limiting groove 24 is ninety degrees, so that the rotating shaft 20 can rotate ninety degrees. The swing rod 23 is installed in the sector-shaped limiting groove 24. The rotating shaft 20 is rotated through the swing rod 23, and the mounting plate 21 is rotated through the rotating shaft 20, so as to open the blockage of the rubber plug 22 on the oil outlet of the oil cavity 15, so that the hydraulic oil 17 enters the chamber surrounded by the inner wall of the outer cylinder 1 and the top surface of the middle cylinder 2, and acts on the second piston 16 at the top of the middle cylinder 2, so as to push the middle cylinder 2 to move axially along the inner cylinder 3 and compress the return spring 6 and the thick spring 8; and when the device is used up and returns to the initial state, by rotating the swing rod 23, the rubber plug 22 is restored to the initial position to block the oil outlet of the oil cavity 15, so as to avoid the impact head 12 popping out due to accidental touch during the carrying process of the device, causing damage to surrounding items and harm to the carrying personnel.

[0050] One end of a swing spring 25 is connected to the end of the swing rod 23 far from the rotating shaft 20, and the other end of the swing spring 25 is fixed at a position near the rotating shaft 20 at the top of the outer cylinder 1. When the swing rod 23 rotates to a certain position, the swing rod 23 is limited by the swing spring 25 to prevent the swing rod 23 from moving when not being rotated by an external force, affecting the flow of the hydraulic oil 17.

[0051] As Figure 7 and Figure 8As shown, a mounting cavity 26 is provided on the side of the oil cavity 15 in the outer cylinder 1, and the mounting cavity 26 is arranged along the axial direction of the outer cylinder 1. A deflection seat 28 is installed at the bottom end surface of the mounting cavity 26, and an impact head 27 is connected to the bottom end surface of the deflection seat 28. The axial direction of the impact head 27 is parallel to the axial direction of the outer cylinder 1. A second striker 29 is movably installed on the top of the deflection seat 28, and the second striker 29 can be deflected at a certain angle on the deflection seat 28; a tightening sleeve 30 is installed in the middle position of the mounting cavity 26, and a deflection spring 31 is installed between the tightening sleeve 30 and the deflection seat 28. The deflection spring 31 is sleeved on the second striker 29. When the outer cylinder 1 moves toward the glass, the tightening sleeve 30 tightens the deflection spring 31, and then the deflection spring 31 is used to straighten the second striker 29. A hammer 32 is installed above 30, and a cylindrical groove 33 is provided on the bottom end surface of the hammer 32. The top of the hammer 32 is connected to one end of a force storage spring 34, and the other end of the force storage spring 34 is fixed to the top inner wall of the mounting cavity 26. When the outer cylinder 1 moves toward the glass, the force storage spring 34 and the deflection spring 31 will be compressed to accumulate elastic potential energy. When the deflection spring 31 straightens the second striker 29, the cylindrical groove 33 is aligned with the top of the second striker 29, and the hammer 32 will move toward the second striker 29 under the action of the force storage spring 34. At the same time, the top end of the second striker 29 collides with the inner wall of the cylindrical groove 33. The second striker 29 transmits the impact force generated by the collision to the impact head 27 through the deflection seat 28, and the glass is struck by the impact head 27, and the impact head 12 is cooperated to achieve rapid breaking of the glass.

[0052] The present invention provides a security glass breaking device, which is used to operate the above-mentioned security glass breaking device, including the following steps:

[0053] The operator holds the outer tube 1 so that the bottom end of the inner tube 3 contacts the glass;

[0054] The outer cylinder 1 is pressed to move toward the glass. During the movement of the outer cylinder 1, the volume of the chamber formed by the inner wall of the outer cylinder 1 and the top surface of the middle cylinder 2 decreases. At the same time, the guide member pushes the hydraulic oil 17 filled in the oil chamber 15 into the chamber formed by the inner wall of the outer cylinder 1 and the top surface of the middle cylinder 2, pushing the middle cylinder 2 to move along the inner cylinder 3 toward the glass. The middle cylinder 2 compresses the elastic energy storage assembly to store energy. During the movement of the middle cylinder 2, the protrusion 14 pushes the resistance ring 9 out of the open groove 10. The elastic energy storage assembly then pushes the impact head 12 on the resistance ring 9 to impact and break the glass.

[0055] Specifically, the operator holds the outer tube 1 and presses the contact plate 19 and the bottom end of the inner tube 3 against the glass;

[0056] The outer cylinder 1 is pressed to move it toward the glass. During the movement of the outer cylinder 1, the second piston 16 moves toward the top end surface of the upper outer cylinder 1. By toggling the rocker arm 23 and utilizing the action of the rocker spring 25, the rocker arm 23 is moved to the other side of the fan-shaped limit groove 24. At this time, the rocker arm 23 will drive the rotating shaft 20 to rotate 90 degrees. The rotating rotating shaft 20 will drive the mounting plate 21 to deflect together, so that the mounting plate 21 drives the rubber plug 22 to move, opening the oil outlet of the oil chamber 15. The second piston 16 pushes the hydraulic oil 17 in the oil chamber 15 into the chamber between the first piston 4 and the top end surface of the outer cylinder 1. According to Pascal's principle, the second piston 16 is subjected to the pressure applied by the guide rod 18, which generates a pressure increment inside the system. The first piston 4 is also located inside this system, so the first piston 4 will also be subjected to a pressure increment of the same size. Since the area of the top end surface of the first piston 4 is several times that of the top end surface of the second piston 16, the pressure acting on the first piston 4 will increase several times its original value, thereby pushing the middle cylinder 2 to move axially along the inner cylinder 3 toward the glass. When the middle cylinder 2 moves, the thick spring 8 is compressed by the second fixing plate 7, and the return spring 6 is compressed by the first fixing plate 5. The thick spring 8 and the return spring 6 are both compressed and accumulate elastic potential energy. During the downward movement of the middle cylinder 2, the protrusion 14 on the middle cylinder 2 contacts the side of the resistance ring 9 and pushes it inward. When the resistance ring 9 is pushed inward a certain distance, it will disengage from the open groove 10, thereby releasing the restriction of the open groove 10 on the resistance ring 9. The elastic potential energy of the return spring 6 and the thick spring 8 is released, pushing the first striker 11 and the impact head 12 to move rapidly downward, so that the impact head 12 strikes and breaks the glass.

[0057] At the same time, as the outer tube 1 moves toward the glass, the deflection spring 31 will be compressed. Initially, due to the action of the deflection spring 31, the top of the second striker 29 is in an inclined state and will contact the side of the hammer 32. As the second striker 29 moves upward, it will drive the hammer 32 to move upward and compress the storage spring 34 to accumulate elastic potential energy. Then the second striker 29 continues to move upward and is affected by the narrowing effect of the tightening mouth 30. The deflection spring 31 will straighten the second striker 29 so that the top of the second striker 29 is aligned with the cylindrical groove 33 in the middle of the hammer 32. At this time, the storage spring 34 releases the elastic potential energy, driving the hammer 32 to drop rapidly so that the hammer 32 hits the second striker 29. The impact force generated by the impact is transmitted to the impact head 27, and the impact force generated by the impact head 27 is used to assist the impact head 12 to break the glass.

[0058] After use, the return spring 6 and the thick spring 8 release elastic potential energy, pushing the middle cylinder 2 and the inner cylinder 3 back to their initial positions. At the same time, the hydraulic oil 17 is sucked into the oil chamber 15 under the suction force generated when the second piston 16 returns to its initial position, and the deflection seat 28 returns to its initial position under the action of the deflection spring 31, rotating the swing rod 23. Using the action of the swing spring 25, the swing rod 23 is returned to its initial position. At this time, the swing rod 23 drives the rotating shaft 20 to rotate by ninety degrees. The rotating shaft 20 drives the mounting plate 21 to deflect together, causing the mounting plate 21 to drive the rubber plug 22 back to its initial position to block the oil outlet of the oil chamber 15.
