Description

Technical Field

[0001] This utility model relates to the field of glass breaking devices, specifically to a manual window breaking device. Background Technology

[0002] With the continuous development of urban transportation and the increasing number of vehicles, safety hazards are also increasing. In the event of an emergency such as a fire or explosion in a closed bus, passenger vehicle, subway, or light rail carriage, it is necessary to escape from the carriage in a short time. In dangerous situations, the doors often cannot be opened, so it is necessary to break the window to escape.

[0003] There are various types of tempered glass breaking devices available today, with operation methods including electric, manual, and manual / automatic hybrid types; they are installed in fixed or portable configurations; electric devices require a power supply, while portable devices are small and easy to carry, but their placement is not fixed, posing a risk of them being lost in an emergency. Furthermore, escapees often lack experience and cannot control the effective hammering force and striking point, thus delaying the process. Utility Model Content

[0004] The purpose of this invention is to provide a manual window-breaking device to solve the technical problems of inconvenience and safety hazards in existing window-breaking devices. It provides a compact, safe, reliable, instantaneous glass-breaking, and easy-to-install fixed manual window-breaking device, mainly for emergency rescue applications such as breaking tempered glass curtain walls in buses, cars, and public places.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a manual window-breaking device, including a base with a central through hole, an impact punch, and a striking cover. The base and the striking cover are connected as a whole by a pin. The top center of the striking cover is provided with a concave through hole. One end of the pin is connected to the concave through hole, and the other end is connected to the impact punch. The pin passes through the central through hole of the base and is connected as a whole by a safety pin.

[0007] Furthermore, the impact punch is a conical body, which is connected to the shaft pin by riveting, interference fit or thread fixing.

[0008] Furthermore, the base is provided with a transverse positioning through hole, the lower end of the shaft pin is provided with a positioning hole, a safety pin is provided between the transverse positioning through hole and the positioning hole, and a locking steel ball is provided at the front end of the safety pin to prevent the safety pin from falling off.

[0009] To ensure the stability of the impact punch and prevent movement and abnormal noise, the safety pin passes through both the positioning hole of the shaft pin and the transverse positioning through hole of the base, locking the shaft pin in place so that it cannot move up or down; at the same time, it confines the tip of the impact punch within the central through hole of the base so that it does not exceed the bottom plane of the base.

[0010] Furthermore, in order to prevent the cover from falling off after the safety pin is pulled out, the lower end of the pin is provided with an annular groove, and the upper and lower ends of the central through hole of the base are provided with two stepped holes. The upper stepped hole holds a spring, and the lower stepped hole restricts the lower end of the pin annular groove so that it cannot move upward and fall out.

[0011] Furthermore, in order to allow the impact punch to move up and down with the cover, a spring is fitted on the pivot pin. The spring is located between the platform inside the base and the top of the cover. The transverse positioning through hole of the base is located in the area below the platform of the base.

[0012] Furthermore, to ensure a firm connection between the pin and the cover, a fixing hole is provided at the concave through-hole connection end of the pin and the cover, and the cover and the pin are fixed by a fixing component.

[0013] Furthermore, to facilitate pulling the safety pin, a pull ring is provided at the end of the safety pin.

[0014] Furthermore, in order to fix the device to the tempered glass, double-sided adhesive tape is also provided on the bottom plane of the base.

[0015] Based on the above technical solution, the embodiments of this utility model can produce at least the following technical effects:

[0016] (1) This utility model breaks glass by striking, which is instantaneous and safe and reliable.

[0017] (2) The present invention locks the shaft pin with a safety pin, which limits the height of the cover and positions the impact punch, making the structure compact and stable.

[0018] (3) The upper and lower step holes of the base of this utility model not only fix the spring, but also limit the upward movement of the shaft pin, making the structure safe and reliable.

[0019] (4) This utility model has a simple structure and is easy to install. Attached Figure Description

[0026] Example 1

[0027] like Figure 1-2 As shown, this utility model provides a manual window breaking device, including a base 4 with a central through hole, an impact punch 7 and a striking cover 1. The base 4 and the striking cover 1 are connected as a whole by a pivot pin 9. The top center of the striking cover 1 is provided with a concave through hole. One end of the pivot pin 9 is connected to the concave through hole and the other end is connected to the impact punch. The pivot pin 9 passes through the central through hole of the base 4 and is connected as a whole by a safety pin 3.

[0028] In this embodiment, the base 4 is provided with a transverse positioning through hole, the lower end of the shaft pin 9 is provided with a positioning hole, a safety pin 3 is provided between the transverse positioning through hole and the positioning hole, and a locking steel ball 6 is provided at the front end of the safety pin 3.

[0029] In this embodiment, the lower end of the shaft pin 9 is also provided with an annular groove, and the upper and lower ends of the central through hole of the base 4 are provided with two stepped holes. The upper stepped hole holds the spring 8, and the lower stepped hole restricts the lower end of the annular groove of the shaft pin 9 so that it cannot move upward and get out.

[0030] In this embodiment, a spring 8 is sleeved on the shaft pin 9, and the spring 8 is disposed between the platform inside the base 4 and the top of the cover 1.

[0031] In this embodiment, the pin 9 and the concave through hole of the cover 1 are provided with a fixing hole, and the cover 1 and the pin 9 are fixed by the fixing member 10.

[0032] In this embodiment, the end of the safety pin 3 is provided with a pull ring 2.

[0033] In this embodiment, the bottom plane of the base 4 is also provided with double-sided adhesive tape 5.

[0034] In this embodiment, the impact punch 7 is a conical body, which is connected to the shaft pin 9 by riveting, interference fit or thread fixing.

[0035] The operating mechanism of this utility model is as follows: The device is fixed to the glass by double-sided adhesive tape 5. When the tempered glass needs to be broken, the pull ring 2 is put on and the safety pin 3 is pulled. After the flap 1 is unlocked, it pops up and strikes the flap 1. The flap 1 drives the shaft pin 9 to move downward quickly. The impact punch 7 hits the tempered glass within 1 second, causing the tempered glass to shatter instantly and forming an escape channel.
