Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a fire hammer for fire safety. Background Technology

[0002] Vehicle fire hammers are a common emergency rescue tool in cars and trains. They are mainly used to break the glass to escape in emergency situations, or to break the glass window where the emergency stop button is located.

[0003] In existing technologies, vehicle fire safety hammers are used by personnel manually striking specific locations on the window (e.g., the four corners) with the hammer. While this action is simple, in actual operation, personnel are prone to panic in emergency situations, making it easy to interfere with the action of taking the hammer out and striking. In addition, many people are unfamiliar with the striking locations on the window, leading to failed attempts to break the window, and there are also cases where insufficient strength results in insufficient striking force and failure. Therefore, existing vehicle fire safety hammers need improvement. Based on this, a fire safety hammer for fire protection is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a fire hammer for fire safety in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire hammer for fire safety, comprising a shell assembly, a hammering assembly, and a locking assembly. The shell assembly includes a fixed cylindrical shell, a striking through hole, and a strong adhesive layer. The striking through hole is located at the front end of the fixed cylindrical shell, and the strong adhesive layer is bonded to the front end of the fixed cylindrical shell. The fixed cylindrical shell is bonded to a glass window via the strong adhesive layer, and the strong adhesive layer is aligned with the striking point of the glass window.

[0006] The hammering assembly is disposed inside the fixed cylinder shell and extends to the rear end of the fixed cylinder shell. The locking assembly is distributed at the rear end of the fixed cylinder shell and is used to lock the hammering assembly in the state of retracting inside the fixed cylinder shell.

[0007] By removing the locking assembly to release the retracted locking of the hammering assembly, the hammering assembly releases its elastic force and passes through the striking hole to strike the striking point of the glass window, thereby breaking the glass window.

[0008] As a further embodiment of this utility model: the hammering assembly includes a hammer head, a limiting slider, a connecting rod, a compression spring, and a through hole;

[0009] The hammer, the limiting slider, and the connecting rod are fixedly connected in sequence along the horizontal direction. The hammer, the limiting slider, and the connecting rod are distributed inside the fixed cylinder shell. The front end of the hammer is aligned with the striking through hole. The connecting rod extends through to the rear end of the fixed cylinder shell. The through hole is opened inside the connecting rod and completely penetrates both sides of the connecting rod.

[0010] The compression spring is distributed between the limiting slider and the inner wall side of the fixed cylinder and is sleeved on the outside of the connecting rod;

[0011] When the hammer head is fully retracted into the fixed cylinder shell, the compression spring is in a contracted state. The through holes are located at the rear end of the fixed cylinder shell. The locking assembly engages with the through holes to lock the hammer head in the contracted state.

[0012] After the locking assembly is removed, the hammer head quickly pops out under the elastic force of the compression spring, thus breaking the glass window.

[0013] As a further improvement of this utility model: the inner and outer diameters of the limiting slider are matched with the inner diameter of the fixed cylinder shell, and the outer diameter of the hammer head is smaller than the inner diameter of the striking through hole.

[0014] As a further embodiment of this utility model: the locking assembly includes a locking pin, a pull ring, a connecting end, an annular groove, a limiting ring piece, an arc-shaped spring piece, and an arc-shaped card;

[0015] The connecting end and the pull ring are respectively fixed to the upper and lower ends of the locking pin. The locking pin is inserted into the inside of the through hole and fits against the rear end of the fixed cylinder shell to lock the hammer head in the retracted state.

[0016] The annular groove is formed at the position where the connecting end meets the locking pin;

[0017] Multiple arc-shaped spring pieces are provided, and the multiple arc-shaped spring pieces are arranged in a ring and fixed to the bottom end of the limiting ring piece. The arc-shaped card is formed on the bottom end of the arc-shaped spring piece. The limiting ring piece and the arc-shaped spring piece are sleeved on the outside of the connecting end. The arc-shaped card is engaged in the inner side of the annular slot. The horizontal height of the compression spring is higher than the horizontal height of the upper surface of the fixed cylinder shell, which is used to limit the downward movement of the locking pin.

[0018] As a further embodiment of this utility model: the outer diameter of the locking pin matches the inner diameter of the through hole, the outer diameter of the connecting end is smaller than the outer diameter of the locking pin, the outer diameter of the limiting ring is larger than the outer diameter of the locking pin, the inner diameter of the distribution of the plurality of arc-shaped spring pieces and the inner diameter of the limiting ring are larger than the outer diameter of the connecting end, and the minimum inner diameter of the distribution of the plurality of arc-shaped cards matches the inner ring diameter of the annular slot.

[0019] As a further improvement of this utility model: a tail end block is fixed at the rear end of the connecting rod, and the outer diameter of the tail end block is larger than the outer diameter of the connecting rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By incorporating a hammer assembly with a quick-release function, glass windows can be easily broken. Compared to the traditional manual removal and hammering action, pulling the ring to release the hammer head is simpler and easier to implement. Furthermore, the spring force provides sufficient striking force to the hammer head, solving the problem of failure due to insufficient striking force. In addition, by aligning the device with the striking position on the glass window during installation, the problem of failure due to unfamiliarity with the striking position is solved.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5In this embodiment of the utility model, a fire hammer for fire safety includes a shell assembly 1, a hammering assembly 2, and a locking assembly 3. The shell assembly 1 includes a fixed cylinder shell 101, a hammering through hole 102, and a strong adhesive layer 103. The hammering through hole 102 is opened at the front end of the fixed cylinder shell 101, and the strong adhesive layer 103 is bonded to the front end of the fixed cylinder shell 101. The fixed cylinder shell 101 is bonded to the glass window through the strong adhesive layer 103, and the strong adhesive layer 103 is aligned with the hammering point of the glass window.

[0030] The hammering assembly 2 is disposed inside the fixed cylindrical shell 101 and extends to the rear end of the fixed cylindrical shell 101. The locking assembly 3 is distributed at the rear end of the fixed cylindrical shell 101 and is used to lock the hammering assembly 2 in the state of retracting inside the fixed cylindrical shell 101.

[0031] By removing the locking component 3 to release the retraction lock on the hammering component 2, the hammering component 2 releases its elastic force and passes through the striking through hole 102 to strike the striking point of the glass window, thereby realizing the glass window breaking operation.

[0032] The hammering assembly 2 includes a hammer head 201, a limiting slider 202, a connecting rod 203, a compression spring 205, and a through hole 206;

[0033] Hammer head 201, limiting slider 202, and connecting rod 203 are fixedly connected in sequence along the horizontal direction. Hammer head 201, limiting slider 202, and connecting rod 203 are distributed inside the fixed cylinder shell 101. The front end of hammer head 201 is aligned with the striking through hole 102. The connecting rod 203 extends through to the rear end of the fixed cylinder shell 101. Through hole 206 is opened inside the connecting rod 203 and completely penetrates both sides of the connecting rod 203.

[0034] Compression springs 205 are distributed between the limiting slider 202 and the inner wall side of the fixed cylinder shell 101 and are sleeved on the outside of the connecting rod 203;

[0035] When the hammer 201 is fully retracted into the fixed cylinder shell 101, the compression spring 205 is in a contracted state. The through hole 206 is located at the rear end of the fixed cylinder shell 101. The locking component 3 is engaged with the through hole 206 to lock the hammer 201 in the contracted state.

[0036] After the locking component 3 is removed, the hammer 201 quickly pops out under the elastic force of the compression spring 205 to break the glass window;

[0037] Locking assembly 3 includes a locking pin 301, a pull ring 302, a connecting end 303, an annular groove 304, a limiting ring 305, an arc-shaped spring 306, and an arc-shaped clip 307.

[0038] The connecting end 303 and the pull ring 302 are respectively fixed to the upper and lower ends of the locking pin 301. The locking pin 301 is inserted into the inside of the through hole 206 and fits against the rear end of the fixed cylinder shell 101 to lock the hammer head 201 in the retracted state.

[0039] The annular groove 304 is formed at the position where the connecting end 303 meets the locking pin 301;

[0040] Multiple arc-shaped spring pieces 306 are provided, and the multiple arc-shaped spring pieces 306 are arranged in a ring and fixed to the bottom end of the limiting ring piece 305. The arc-shaped card 307 is formed on the bottom end of the arc-shaped spring piece 306. The limiting ring piece 305 and the arc-shaped spring piece 306 are sleeved on the outside of the connecting end 303. The arc-shaped card 307 is engaged in the inside of the annular slot 304. The horizontal height of the compression spring 205 is higher than the horizontal height of the upper surface of the fixed cylinder shell 101, which is used to limit the downward movement of the locking pin 301.

[0041] In this embodiment, the operation method of this fire hammer is as follows:

[0042] The hammer assembly 2 is in a retracted state when it leaves the factory, that is, the hammer head 201 is stored inside the fixed cylindrical shell 101, the locking pin 301 is inserted into the through hole 206 and fits against the rear end of the fixed cylindrical shell 101, and the limiting ring 305 is engaged with the inner side of the annular groove 304 by the arc card 307. When the locking pin 301 moves down, it collides with the outer wall of the fixed cylindrical shell 101 through the limiting ring 305, which can realize the downward movement limitation of the locking pin 301.

[0043] When using it, first remove the release paper on the strong adhesive layer 103, and then fix the entire device to the glass window with the strong adhesive layer 103, with the striking through hole 102 aligned with the striking position of the glass window.

[0044] When an emergency occurs and the glass window needs to be broken, manually pull the pull ring 302 to move the locking assembly 3 downwards. At this time, the limiting ring 305, the arc-shaped spring 306, and the arc-shaped clip 307 are blocked by the fixed cylinder shell 101 and cannot continue to move downwards. The arc-shaped clip 307 is subjected to the squeezing force from the connecting end 303, and its arc-shaped spring 306 and arc-shaped clip 307 deform outwards relative to the annular groove 304, releasing the jamming state between the arc-shaped clip 307 and the annular groove 304. Finally, the limiting ring 305, the arc-shaped spring 306, and the arc-shaped clip 307 are separated from the connecting end 303. At this time, the pull ring 302, the locking pin 301, and the connecting end 303 can be smoothly separated from the connecting rod 302, thereby releasing the lock on the connecting rod 302.

[0045] At this time, the hammer head 201, the limiting slider 202, and the connecting rod 203 move rapidly under the elastic force of the compression spring 303, and the hammer head 201 passes through the striking hole 102 to strike the glass window.

[0046] The combination of these components enables convenient window breaking. Compared to the traditional manual removal and hammering action, pulling the ring 302 to release the hammer head 201 is simpler and easier to implement. The spring force of the compression spring 205 provides sufficient striking force for the hammer head 201 (it should be noted that the compression spring 205 is always in a compressed state), solving the problem of failure due to insufficient striking force. In addition, by aligning the device with the striking position of the window during installation, the problem of failure due to unfamiliarity with the striking position is solved.

[0047] Please refer to this carefully. Figures 2-3 The inner and outer diameters of the limiting slider 202 match the inner diameter of the fixed cylinder shell 101, and the outer diameter of the hammer head 201 is smaller than the inner diameter of the striking through hole 102.

[0048] In this embodiment, the structure in which the inner and outer diameters of the limiting slider 202 match the inner diameter of the fixed cylinder shell 101 ensures the stable movement of the hammer head 201. The structure in which the outer diameter of the hammer head 201 is smaller than the inner diameter of the striking through hole 102 allows the hammer head 201 to pass smoothly through the striking through hole 102 to strike the glass window.

[0049] Please refer to this carefully. Figures 1-5 The outer diameter of the locking pin 301 matches the inner diameter of the through hole 206. The outer diameter of the connecting end 303 is smaller than the outer diameter of the locking pin 301. The outer diameter of the limiting ring 305 is larger than the outer diameter of the locking pin 301. The inner diameters of the multiple arc-shaped spring pieces 306 and the inner diameter of the limiting ring 305 are larger than the outer diameter of the connecting end 303. The minimum inner diameter of the multiple arc-shaped cards 307 matches the inner ring diameter of the annular slot 304.

[0050] In this embodiment, it should be noted that the locking pin 301, pull ring 301, and connecting end 303 are all made of metal to ensure a stable locking state, while the limiting ring 305, arc-shaped spring 306, and arc-shaped card 307 are all made of plastic to facilitate deformation and separation.

[0051] By using the structure where the inner diameter of the multiple arc-shaped spring pieces 306 is distributed and the inner diameter of the limiting ring piece 305 is larger than the outer diameter of the connecting end 303, when the limiting ring piece 305 is subjected to the squeezing force from the fixed cylinder shell 101, the arc-shaped card 307 can be moved out of the annular slot 304 to the outside of the connecting end 303 with a small deformation under force. This makes it easier to remove the locking assembly 3 with less force, allowing even people with less strength to operate it smoothly.

[0052] Please refer to this carefully. Figures 1-4 The rear end of the connecting rod 203 is fixed with a tail end block 204, and the outer diameter of the tail end block 204 is larger than the outer diameter of the connecting rod 203.

[0053] In this embodiment: the tail end round block 204 is provided to provide a striking part for the connecting rod 203. This structure is mainly to prevent the compression spring 305 from failing. The tail end round block 204 can be struck by other objects to make the hammer head 201 move out to strike the glass window.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
