Description

Technical Field

[0001] This utility model relates to the field of automotive safety equipment technology, and more specifically, to an automotive window breaker. Background Technology

[0002] A car window breaker is a highly efficient and safe tool designed specifically for emergency escape. It typically uses a high-strength alloy or spring hammer structure. When a vehicle encounters a fire, falls into water, or is involved in a traffic accident that prevents the doors from opening, it can quickly shatter the tempered glass by precisely striking the corner of the window, using the instantaneous impact force to create an escape route for the driver and passengers.

[0003] Existing examples, such as the multi-purpose window breaker disclosed in application number CN202420207831.5, include a seat belt buckle, a firing pin tip, and a window breaker hammer body. One end of the seat belt buckle is fixedly connected to the firing pin tip, and the other end of the seat belt buckle is fixedly connected to the window breaker hammer body.

[0004] When a car is involved in a collision or other accident, the door may be deformed and the seat may be displaced. Since the hammer of the aforementioned window breaker is fixedly connected to the seat belt buckle, its length is fixed. Therefore, it may not be able to break through the glass suitable for escape when using it, which is not adaptable enough. Utility Model Content

[0005] Therefore, in order to solve the problem that the hammer body cannot be changed in length, which may result in the inability to break the glass, this utility model provides an automotive window breaker, the specific technical solution of which is as follows: A car window breaker includes a seat belt buckle body, a connecting rod, and a hammer. The seat belt buckle body has a first threaded hole, one end of the connecting rod is threaded into the first threaded hole, and the hammer is installed at the other end of the connecting rod.

[0006] By adopting the above technical solution, when an accident occurs and a window needs to be broken, the driver and passengers only need to unbuckle their seat belts and then grab the seat belt buckle to break the glass. If, due to special circumstances such as seat displacement, the connecting rod is slightly shorter than required and cannot be used for striking, the connecting rod can be rotated to increase its length through a threaded process, thus improving its applicability.

[0007] Furthermore, the connecting rod includes a first rod body and a second rod body, one end of the first rod body is threadedly installed in the first threaded hole, one end of the second rod body is threadedly installed in the other end of the first rod body, and the hammer body is installed at the end of the second rod body away from the first rod body.

[0008] Furthermore, the cross-sectional area of ​​the first rod is the same as that of the second rod, a threaded rod is provided at one end of the second rod near the first rod, and a second threaded hole is provided at one end of the first rod near the second rod, and the threaded rod is threaded into the second threaded hole.

[0009] Furthermore, the thread helix direction of the first threaded hole is opposite to that of the thread helix direction of the second threaded hole.

[0010] Furthermore, a protective cover is provided on the seat belt buckle body at the position corresponding to the connecting rod.

[0011] Furthermore, the seat belt buckle body has a circumferentially formed insertion groove at the position corresponding to the protective shell, and the end of the protective shell is inserted into the insertion groove.

[0012] Furthermore, the protective shell is cylindrical, and the protective shell is threadedly connected to the wall of the insertion groove.

[0013] Furthermore, each of the outer walls of the connecting rod is provided with a mounting groove, and a plug-in block is slidably mounted in the mounting groove. The protective shell is provided with a plug-in hole corresponding to the position of the plug-in block.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0022] Example 1 like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a car window breaker, comprising a seatbelt buckle body 1, a connecting rod 2, a hammer 3, and a protective shell 4. The seatbelt buckle body 1 has a first threaded hole 11. One end of the connecting rod 2 is threaded into the first threaded hole 11, and the hammer 3 is installed at the other end of the connecting rod 2. The length of the connecting rod 2 can be adjusted by rotating the connecting rod 2 and adjusting the thread, thus adapting to more situations and improving its applicability. The protective shell 4 covers the seatbelt buckle body 1 at the position corresponding to the connecting rod 2, thereby separating the hammer 3 when not in use and reducing injury to the driver and passengers. A handle 5 is provided on one side of the seatbelt buckle body 1, and the handle 5 has a grip groove 51 for the fingers to be inserted, so that the driver and passengers can more stably grasp the window breaker for use.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, the connecting rod 2 includes a first rod body 21 and a second rod body 22. One end of the first rod body 21 is threaded into the first threaded hole 11, and one end of the second rod body 22 is threaded into the other end of the first rod body 21. The hammer body 3 is installed at the end of the second rod body 22 away from the first rod body 21. Thus, by rotating the first rod body 21 and the second rod body 22 relative to each other, the length of the connecting rod 2 can be further increased, improving its adaptability.

[0024] The cross-sectional area of ​​the first rod 21 is the same as that of the second rod 22. A threaded rod 221 is provided at the end of the second rod 22 near the first rod 21. A second threaded hole 211 is provided at the end of the first rod 21 near the second rod 22. The threaded rod 221 is threaded into the second threaded hole 211, thereby ensuring the overall strength of the connecting rod 2. The helix direction of the thread in the first threaded hole 11 is opposite to that in the second threaded hole 211. Therefore, when the second rod 22 is rotated, the first rod 21 will not continue to rotate out, causing the first rod 21 to disengage from the seat belt buckle body 1, thus affecting its normal use.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the seat belt buckle body 1 has a circumferentially provided insertion groove 12 at the position corresponding to the protective shell 4, and the end of the protective shell 4 is inserted into the insertion groove 12; the protective shell 4 is cylindrical, and the protective shell 4 is threadedly connected to the groove wall of the insertion groove 12; thereby, the protective shell 4 can be fixed, and the protective shell 4 can be removed more quickly in subsequent use.

[0026] Specifically, such as Figure 1 As shown, the seat belt buckle body 1 includes a connector 13 and a buckle 14. One end of the connector 13 is used to be fixedly connected to the seat belt, and the buckle 14 is fixedly installed on the other end of the connector 13. The buckle 14 is used to fasten into the seat belt buckle.

[0027] The implementation principle of Example 1 is as follows: When an accident occurs and a window needs to be broken, the driver and passengers only need to unbuckle their seat belts, then rotate the protective shell 4 to remove the protective shell 4, grab the seat belt buckle body 1 to break the glass. However, if the connecting rod 2 is slightly shorter than expected due to special circumstances such as seat displacement, and cannot be struck, the first rod 21 and the second rod 22 can be rotated to adjust the length of the connecting rod 2.

[0028] Example 2 like Figure 3 and Figure 4 As shown, the difference from Embodiment 1 is that mounting grooves 24 are provided on both sides of the connecting rod 2, and the mounting grooves 24 are slidably mounted with the plug-in block 25. The protective shell 4 is provided with a plug-in hole 41 corresponding to the position of the plug-in block 25. One end of the plug-in block 25 extends out of the mounting groove 24 and passes through the plug-in hole 41. The end of the plug-in block 25 passing through the plug-in hole 41 is provided with a guide arc surface 251. An elastic element 26 is provided between the plug-in block 25 and the bottom of the mounting groove 24. In this embodiment, the elastic element 26 is a spring, and the two ends of the elastic element 26 are respectively fixedly connected to the bottom of the mounting groove 24 and the plug-in block 25.

[0029] The implementation principle of Example 2 is as follows: When it is necessary to remove the protective shell 4, the driver or passenger only needs to press two fingers on the corresponding plug block 25 position so that the guide arc surface 251 enters the plug hole 41, and then pull out the protective shell 4. Through the guiding effect of the guide arc surface 251, the plug block 25 smoothly leaves the plug hole 41, allowing the protective shell 4 to detach smoothly.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
