Description

Technical Field

[0001] This utility model relates to the field of piercing jewelry technology, and in particular to a spring-loaded electric window breaker. Background Technology

[0002] A window breaker is a tool used in emergencies to quickly break car windows. It is widely used in enclosed spaces such as cars, subways, and public transportation to help people escape quickly in emergencies such as fires, drownings, and traffic accidents. The core working principle of a window breaker is based on the physical principles of pressure and force. By utilizing the small contact area between a high-hardness metal impact head and the glass, it generates greater pressure with the same striking force, thus shattering the glass. However, existing window breaker methods require the user to hold and forcefully swing the device to strike the glass. Since users of different sizes produce different striking forces, those with weaker striking force may need to strike repeatedly to break the glass. This is time-consuming, laborious, and can easily lead to missing the optimal escape opportunity. Therefore, it is inconvenient to use and has poor window-breaking effectiveness. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a spring-loaded electric window breaker with a compact and reasonable structure.

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, this utility model discloses a spring-loaded electric window breaker, including a spring-loaded component 1, a reducer 2 connected to the spring-loaded component 1, and a drive motor 3 driven by the reducer 2. The drive motor 3 drives the spring-loaded component 1 to move via the reducer 2. The spring-loaded component 1 includes a rotating part 11, an impact head 12 disposed on the rotating part 11, a sleeve 13 disposed on the reducer 2, and a spring 14 disposed between the rotating part 11 and the sleeve 13. The rotating part 11 is provided with a spiral groove 15, and the sleeve 13 is provided with a cam block 16. The rotating part 11 is rotatably connected to the output end of the reducer 2, so that the spiral groove 15 and the cam block 16 are slidably connected, thereby driving the impact head 12 to pass through the spring 14 and protrude out of the sleeve 13.

[0027] During operation, the user turns on the drive motor 3, which drives the rotating component 11 to rotate via the reducer 2. Since the sleeve 13 is fixedly mounted outside the reducer 2, the rotating component 11 rotates spirally through the helical groove 15 and the cam block 16, causing the impact head 12 to pass through the spring 14 and protrude from the sleeve 13. When the drive motor 3 is turned off, the spring 14, compressed between the rotating component 11 and the sleeve 13, is pushed back to its original position by the elastic force of the spring, causing the impact head 12 to return to the sleeve 13. This achieves electric drive of the impact head 12 to quickly break the glass, eliminating the need for manual operation, enhancing the window-breaking effect, and significantly improving the success rate. The reducer 2 uses a planetary gear reducer 2, which is existing technology and will not be described further. This utility model has a compact and reasonable structure, using an electric drive to quickly impact and break the glass with the impact head 12, saving time and effort, and is simple and convenient to use, thus improving the window-breaking effect.

The housing 4 has an axial notch 43, which is arranged along the axial direction of the housing 4. The cam block 16 protrudes into the axial notch 43. The rotating component 11 is rotatably disposed within the housing 4. Specifically, the housing 4 is disposed between the reducer 2 and the sleeve 13. An external screw passes through the first connecting hole 42 and is then connected and fixed to the first mounting hole 21 to achieve the connection and fixation between the housing 4 and the reducer 2. The axial notch 43 is arranged along the axial direction of the housing 4, and the rotating component 11 is rotatably disposed within the housing 4 so that the cam block 16 can protrude into the axial notch 43, facilitating the sliding connection between the cam block 16 and the helical groove 15. The housing 4 provides good load-bearing protection for the rotating component 11, ensuring its normal operation.

[0029] In this embodiment, the housing 4 is provided with axial strips 44, which protrude from the outer wall of the housing 4. Several axial strips 44 are provided, arranged around the circumference of the housing 4. The sleeve 13 is provided with axial grooves 17, which protrude from the inner wall of the sleeve 13.

The four axial strips 44 are respectively accommodated within the four axial grooves 17, achieving a stable and reliable connection between the housing 4 and the sleeve 13.

[0030] In this embodiment, the outer wall of the sleeve 13 is provided with a groove 18 and a second mounting hole 19. The cam block 16 is provided with a connecting plate 110 and a second connecting hole 111 disposed in the connecting plate 110. The connecting plate 110 is accommodated in the groove 18 so that the second connecting hole 111 communicates with the second mounting hole 19. Specifically, the connecting plate 110 is accommodated in the groove 18, and an external screw is used to pass through the second connecting hole 111 and then connect and fix it to the second mounting hole 19, thereby realizing the connection and fixation between the cam block 16 and the sleeve 13, and the connection is stable and reliable.

[0031] In this embodiment, the outer wall of the sleeve 13 is provided with a receiving hole 112, and the cam block 16 is received in the receiving hole 112 so that the cam block 16 protrudes into the sleeve 13. Specifically, the cam block 16 is received in the receiving hole 112 to facilitate the cam block 16 protruding into the sleeve 13 and to meet the working requirements of the cam block 16 slidingly connecting with the spiral groove 15.

[0032] In this embodiment, a through hole 113 is provided at the end of the sleeve 13 away from the housing 4. The impact head 12 passes through the through hole 113 and protrudes out of the sleeve 13. Specifically, the impact head 12 passes through the through hole 113 and protrudes out of the sleeve 13, which facilitates the impact head 12 to quickly strike and shatter the glass, resulting in a good window-breaking effect.
