Description

Technical Field

[0001] The utility model relates to the technical field of escape hammers, in particular to an emergency window-breaking escape hammer. Background Art

[0002] A window breaker is an auxiliary escape tool installed in a closed cabin. It is usually installed in a place that is easy to get in a closed cabin such as a bus or a passenger car. When a closed cabin such as a vehicle has a fire or falls into water, it can be easily taken out and the glass window door can be smashed for a smooth escape.

[0003] For example, in the prior art, the Chinese utility model with publication number: CN206606163U discloses a safe-to-use bus window-breaking hammer. This utility model overcomes the defects of the existing window-breaking hammers, which are simple in structure and have no safety protection device. When used, the glass fragments splashed by the broken window can easily scratch the window breaker and passengers. In addition, the bus glass currently used is mostly of good quality and high hardness. When the window-breaking hammer is used to hit the glass, there will be a large recoil force, which can easily injure the window breaker's hand and cause the window-breaking hammer to fly away from the hand.

[0004] However, the existing escape hammers require a relatively large force and attack speed to break the glass in a very short time, and the existing escape hammers tend to be miniaturized, which results in the need to swing the hammer multiple times to break the glass for escape, seriously affecting the escape time of personnel, and also reducing the rescue efficiency, causing the victims to miss the best rescue time. Therefore, we need to propose an emergency window-breaking escape hammer. Utility Model Content

[0026] Furthermore, the limit guide groove 9 cooperates with the connecting baffle 6 to guide and limit the extension tube 3. The anti-drop handle 4 prevents the hammer head body 1 from slipping out of the hand during use. The hammer head body 1 can be assembled through the assembly seat 17, and can be rotated and adjusted in conjunction with the adjustment groove 19. The reset spring 10 resets the extension tube 3 to facilitate the storage of the escape hammer. The limit card part 5 is a structure that cooperates with the limit card groove 18 when the extension tube 3 is stored to ensure the stability of the structure. The positioning column 8 is a structure that positions the bottom of the reset spring 10.

[0027] The positioning assembly includes: a positioning baffle 14 disposed inside the assembly groove 12, and a positioning clamping rod 16 connected to the surface of the positioning baffle 14; wherein, a positioning clamping hole 7 is opened on the surface of the extension tube 3, the positioning clamping rod 16 is movably inserted into the inner wall of the positioning clamping hole 7, and positioning sliders 15 are connected to both sides of the positioning baffle 14. The surface of the positioning slider 15 is slidably connected to the inner wall of the assembly groove 12, and a compression spring 13 is disposed inside the assembly groove 12, and one end of the compression spring 13 is connected to the other side of the positioning baffle 14.
