Technical Field

[0001] The utility model relates to the technical field of lighting tools, in particular to a flashlight. Background Art

[0002] As people's demand for use increases, the role and function of flashlights are constantly expanding. It not only has the functions of lighting and calling for help, but also has the functions of cutting seat belts and breaking windows. It is one of the practical tools on the vehicle. The window breaking function on the existing flashlights mostly adopts a push-type window breaker, and its structure is such as a window breaker and an escape tool including the window breaker disclosed in Chinese utility model CN209952074U. The clamping arm on its bracket clamps the outer shell in an open state. When the window breaker is accumulating power, the clamping arm of the bracket is gradually stretched outward by the protrusion on the outer shell. When the window breaker is installed on the escape tool, a certain amount of additional space needs to be reserved around the window breaker to ensure that the clamping arm has enough space to gradually stretch outward, resulting in an increase in the product volume. Flashlight products pursue compactness and portability, so the window breaker structure is not suitable for flashlight products. Utility Model Content

One end of the elastic arm 31 is connected to the outer peripheral wall of the striker 3, and the other end of the elastic arm 31 is a free end, which is in an open state away from the striker 3, and the other end of the elastic arm 31 can be retracted toward the striker 3 after being subjected to force.

[0026] The trigger tube 4 is slidably connected to one end of the active cavity 20. At least a part of the trigger tube 4 extends out of the active cavity 20. A pinhole 40 is provided in the trigger tube 4 for the head of the firing pin 3 to extend out. When the other end of the elastic support arm 31 is in an expanded state, it abuts against the end of one end of the trigger tube 4. After the other end of the elastic support arm 31 contracts toward the direction of the firing pin 3, the elastic support arm 31 is slidably connected to the inner cavity of the trigger tube 4.

[0027] The force storage spring 5 is located at the other end of the active chamber 20 , so that the striker 3 keeps the tendency to extend out of the needle hole 40 .

[0028] The return spring 6 is located in the inner cavity of the trigger tube 4 and is sleeved on one end of the head of the firing pin 3. A first step surface 301 is provided between the middle part and the head of the firing pin 3. One end of the return spring 6 rests on the first step surface 301, and the other end rests in the inner cavity of the trigger tube 4. The elastic force of the return spring 6 is less than the elastic force of the force storage spring 5, and the force storage spring 5 adopts a strong spring with super elastic force.

[0029] A second step surface 302 is provided between the middle and tail of the striker 3 , and the force storage spring 5 is sleeved on the tail of the striker 3 , with one end of the force storage spring 5 resting on the second step surface 302 , and the other end resting on the inner wall of the other end of the active chamber 20 .

[0030] A first guide groove 201 is provided at one end of the side wall of the housing 2, and a first guide block 41 is provided on the outer wall of the trigger cylinder 4. The first guide block 41 is slidably connected in the first guide groove 201. The cooperation between the first guide groove 201 and the first guide block 41 can limit the sliding front and rear ends of the trigger cylinder 4 to prevent excessive sliding out.

[0031] A second guide groove 202 is provided in the middle of the side wall of the housing 2, and a second guide block 32 is provided in the middle of the striker 3, and the second guide block 32 is slidably connected in the second guide groove 202. The cooperation between the second guide groove 202 and the second guide block 32 makes the striker 3 slide more smoothly, which is conducive to the ejection and retraction of the striker 3.

[0032] A rope cutter 22 is disposed on the outer wall of the housing 2 , and the rope cutter 22 can be used for cutting purposes such as cutting a safety belt.

[0033] An end cover 7 is provided at one end of the cylinder 1, and the end cover 7 covers the window breaker to protect the window breaker.

[0034] The working principle of the window breaker function of the flashlight of the utility model is as follows: the movable cavity 20 extends along the front-back direction of the flashlight, the striker 3 is slidably connected in the movable cavity 20 along its length direction, and the trigger tube 4 is slidably arranged at the front end of the movable cavity 20, and its sliding stroke is limited by the cooperation of the first guide groove 201 and the first guide block 41. When the elastic arm 31 is in a natural state, the other end is spread open, the outer wall of the elastic arm 31 abuts against the protrusion 21, and the end of the free end of the elastic arm 31 abuts against the trigger tube 4. When the window breaker function is used, the front end of the trigger tube 4 is aligned with the position to be broken and pressed. After the trigger tube 4 is subjected to force, it pushes the striker 3 inward. During the sliding process of the striker 3, the elastic arm 31 is squeezed after contacting the protrusion 21, and the elastic arm 31 shrinks toward the striker 3. The shrunk elastic arm 31 is separated from the end of the trigger tube 4, and the whole falls into the inner cavity of the trigger tube 31. Under the push of the storage spring 5, the striker 3 pops out of the pinhole 40 toward the front end of the trigger tube 4. When the striker 3 is in the popped-out state, the head of the striker 3 extending from the front end of the window breaker is aimed at a hard object and pressed, and the striker 3 is retracted inwards after being pressed, and at the same time, the trigger cylinder 4 is reset outwards under the action of the reset spring 6, and the elastic arm 31 is restored to the end of the trigger cylinder 4. During the operation of the window breaker, the parts do not need to move and expand toward the periphery, and no additional space needs to be reserved outside the window breaker shell, which effectively saves the product volume and is more suitable for flashlight products.
