Description

Technical Field

[0001] This application relates to the field of safety equipment technology, and in particular to a safety hammer. Background Technology

[0002] In related technologies, safety hammers usually take up a lot of space and are inconvenient to store, or the safety hammer is designed so that the user has to squeeze the spring to pop out the firing pin, which is not conducive to the use of users with less strength. Summary of the Invention

[0003] This application provides a safety hammer, comprising: The shell has a striking opening that communicates with its internal space; The spring pin assembly is disposed in the housing; The driving component is connected to the spring pin assembly; A trigger has a sliding part, a rotating part, and a pressing part along its length. The rotating part is located between the sliding part and the pressing part. The rotating part is rotatably connected to the housing. The sliding part is slidably connected to the driving member along a first direction. Pressing the pressing part drives the trigger to rotate around the rotating part. The sliding part slides relative to the driving member in the first direction and forms a limit in the second direction, thereby driving the driving member to move along the second direction and driving the spring pin assembly to switch from the locked state to the firing state. The first direction and the second direction intersect.

[0004] The safety hammer provided in this application embodiment divides the trigger into a sliding part, a rotating part, and a pressing part. The rotating part is located between the sliding part and the pressing part, and is rotatably connected to the housing. The sliding part is slidably connected to the driving member along a second direction. Thus, when the pressing part is pressed, the arcuate motion of the sliding part around the rotating part can be decomposed in two non-parallel directions: a first direction and a second direction. The motion component in the first direction abuts against the driving member and drives the driving member to slide relative to the housing along the first direction. The motion component in the second direction causes the sliding part itself to slide relative to the driving member along the second direction, preventing the sliding part from deforming the driving member along the second direction. This facilitates the conversion of the arcuate motion of the trigger at the sliding end into a linear motion of the driving member along the first direction, improving the smoothness of triggering the spring assembly and switching it to the firing state. Simultaneously, the trigger-type safety hammer has a smaller overall size, making it easier to store, and the trigger's driving structure requires less effort, reducing the force required for the user to trigger the spring assembly and improving the convenience of using the safety hammer.

[0007] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0008] In the description of the embodiments of this application, it should be noted that the terms "center," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0009] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0010] In related technologies, safety hammers usually take up a lot of space and are inconvenient to store, or the safety hammer is designed so that the user has to squeeze the spring to pop out the firing pin, which is not conducive to the use of users with less strength.

[0011] Based on the above, this application provides a safety hammer 10. Please refer to [link / reference]. Figures 1 to 7 The safety hammer 10 includes a housing 11, a spring pin assembly 12, a drive member 13, and a trigger 14. The spring pin assembly 12 is disposed on the housing 11. The drive member 13 is slidably connected to the housing 11 along a first direction. The drive member 13 is configured to drive the spring pin assembly 12 to switch between a locked state and a firing state. The trigger 14 includes a sliding portion 141, a rotating portion 142, and a pressing portion 143 along its length. The rotating portion 142 is located between the sliding portion 141 and the pressing portion 143. The rotating portion 142 is rotatably connected to the housing 11. The sliding portion 141 is slidably connected to the drive member 13 along a second direction. Pressing the pressing portion 143 drives the sliding portion 141 and the drive member 13 to slide relative to each other in the second direction, and moves the drive member 13 along the first direction, causing the spring pin assembly 12 to switch from a locked state to a firing state. The first direction intersects the second direction.

[0012] It should be noted that the spring pin assembly 12 has a locked state and a firing state. In the locked state, the spring pin assembly 12 is locked inside the housing 11. In the firing state, the spring pin assembly 12 is released from the lock of the housing 11 and bursts out of the striking hole 11a to break the glass.

[0013] The drive member 13 is configured to drive the spring pin assembly 12 to switch between a locked state and a firing state, that is, the drive member 13 slides relative to the housing 11 in a first direction, which can drive the spring pin assembly 12 to unlock from the housing 11 or lock the spring pin assembly 12 inside the housing 11.

[0014] The safety hammer 10 of this application has a trigger 14, that is, the safety hammer 10 in the embodiments of this application is a trigger 14 type or a gun type safety hammer 10.

[0015] The trigger 14 includes a sliding part 141, a rotating part 142, and a pressing part 143 along its length. The rotating part 142 is located between the sliding part 141 and the pressing part 143. Here, the sliding part 141 and the pressing part 143 are located at opposite ends of the trigger 14 along its length. Thus, when the rotating part 142 is rotatably connected to the housing 11, at least a portion of the pressing part 143 is located outside the housing 11, and the sliding part 141 is located inside the housing 11 and is slidably connected to the drive member 13 along the second direction. When the pressing part 143 is pressed, the trigger 14 can rotate around the rotating part 142 and drive the sliding part 141 to make an arc-shaped motion around the rotating part 142.

[0016] It should be noted that the dimensions of different parts in the three directions are different in the same absolute coordinate system. Generally, the length, width and thickness of an object are determined according to the dimensions of the object extending in the three directions, with length > width > thickness.

[0017] For example, Figures 1 to 6 R1 in the equation can be the first direction. Figures 3 to 6 R2 in the equation can be the second direction.

[0018] The safety hammer 10 provided in this application embodiment divides the trigger 14 into a sliding part 141, a rotating part 142, and a pressing part 143. The rotating part 142 is located between the sliding part 141 and the pressing part 143. The rotating part 142 is rotatably connected to the housing 11. The sliding part 141 is slidably connected to the driving member 13 along the second direction. Thus, when the pressing part 143 is pressed, the arc-shaped motion of the sliding part 141 around the rotating part 142 can be decomposed in the first and second directions, which are not parallel to each other. The motion component in the first direction is used to abut against the driving member 13 and drive the driving member 13 to slide relative to the housing 11 along the first direction. The motion component in the second direction causes the sliding part 141 itself to slide relative to the driving member 13 along the second direction. This prevents the sliding part 141 from deforming the driving member 13 by abutting against it along the second direction. This is beneficial for converting the arc-shaped motion of the trigger 14 at the sliding part 141 end into the linear motion of the driving member 13 along the first direction, thereby improving the smoothness of the trigger 14 triggering the spring pin assembly 12 and switching it to the firing state. Meanwhile, the safety hammer 10 with trigger 14 is smaller in size, which is easier to store, and the driving structure of trigger 14 is more labor-saving, which can reduce the force required for the user to trigger the spring pin assembly 12, thus improving the ease of use of the safety hammer 10.

[0019] For example, in one embodiment, the first direction and the second direction can be perpendicular, which can increase the contact force between the sliding part 141 and the driving member 13 in the first direction, thereby improving the stability and reliability of driving the driving member 13.

[0020] In some embodiments, please refer to Figures 4 to 7The rotating part 142 is a rotating shaft. The housing 11 has a rotating hole. The rotating shaft and the rotating hole are rotatably fitted together.

[0021] For example, the pivot is integrally formed with the trigger 14.

[0022] In this embodiment, by defining the rotating part 142 as the rotating shaft, and the rotating hole formed on the housing 11 is rotatably engaged with it, the structure is simpler and more reliable, and it is also beneficial for production and assembly.

[0023] In some embodiments, please refer to Figure 6 and Figure 7 One of the driving member 13 and the sliding part 141 is formed with a groove 13a, and the other of the driving member 13 and the sliding part 141 is formed with a slider. The slider is slidably engaged with the groove 13a.

[0024] Understandably, the groove 13a extends along the second direction, allowing the slider to slide along that direction. Through the interaction between the groove 13a and the slider, on the one hand, the groove 13a provides a smooth and accurate movement path, while the slider can slide easily within it, making the entire movement process more precise and controllable; on the other hand, the groove 13a provides additional support and stability, preventing the slider from wobbling or becoming unstable during movement, resulting in stable movement.

[0025] For example, a groove 13a is formed on the drive member 13, and a slider is formed on the sliding portion 141.

[0026] For example, the slider is cylindrical and integrally formed with the sliding part 141 or the trigger 14. Thus, in an embodiment where the rotating part 142 is a rotating shaft, the housing 11 has a rotating hole, and the rotating shaft and the rotating hole are rotatably engaged, the trigger 14 has a double rotating shaft structure.

[0027] For example, the groove 13a is in the shape of a waist hole or an elongated hole.

[0028] In some embodiments, please refer to Figure 4 and Figure 5 The housing 11 has a striking port 11a communicating with its internal space. The spring pin assembly 12 includes a first elastic element 121 and a striking pin 122. The striking pin 122 is located in the housing 11. The first elastic element 121 connects the driving element 13 and the striking pin 122. In the locked state, the striking pin 122 is locked to the housing 11, and the first elastic element 121 is compressed and stores elastic potential energy under the action of the driving element 13. In the firing state, the striking pin 122 is released from the lock with the housing 11 and, under the action of the first elastic element 121, bursts out of the striking port 11a to shatter the glass.

[0029] The firing pin 122 is located in the housing 11, meaning that in the locked state, the firing pin 122 is located inside the housing 11, and in the firing state, the firing pin 122 is partially located inside the housing 11 and partially extends out of the housing 11 through the striking port 11a.

[0030] The first elastic element 121 connects the driving element 13 and the striking pin 122, so that when the driving element 13 moves toward the striking hole 11a in the first direction, the driving element 13 can compress the first elastic element 121 and store elastic potential energy. When the striking pin 122 disengages from the locking of the housing 11, the striking pin 122 can move toward the striking hole 11a under the action of the elastic potential energy of the first elastic element 121 and burst out of the striking hole 11a, thereby shattering the glass.

[0031] In this embodiment, the driving member 13 and the striking pin 122 are connected by the first elastic member 121. The first elastic member 121 can store a large amount of energy and can instantly drive the striking pin 122 to rush out of the striking hole 11a, which is beneficial to improve the force and reliability of breaking the glass.

[0032] For example, the first elastic element 121 is a spring.

[0033] In some embodiments, please refer to Figure 4 and Figure 5 The firing pin 122 has a first abutment surface 122a, and the housing 11 has a second abutment surface 11e. In the locked state, the first abutment surface 122a and the second abutment surface 11e abut against each other. The driving member 13 drives the first abutment surface 122a to move relative to the second abutment surface 11e until the first abutment surface 122a separates from the second abutment surface 11e, and the firing pin 122 enters the firing state.

[0034] In this embodiment, by providing a first abutting surface 122a and a second abutting surface 11e on the striker 122 and the housing 11 respectively, the striker 122 is locked by the contact between the first abutting surface 122a and the second abutting surface 11e. That is, by contacting the surfaces, the reliability of the lock can be improved, and it is also convenient to unlock the striker 122.

[0035] In some embodiments, please refer to Figure 4 and Figure 5 The driving member 13 is provided with a pushing part 13e, which is used to push the firing pin 122 to move in the direction of disengaging from the second abutting surface 11e.

[0036] Thus, when the drive member 13 moves along the first direction, the drive member 13 can drive the first abutting surface 122a to move relative to the second abutting surface 11e in a direction away from the second abutting surface 11e, for example, in the direction of the central axis of the striking port 11a, which is beneficial to separate the first abutting surface 122a from the second abutting surface 11e and unlock the spring pin assembly 12 from the locked state.

[0037] In some embodiments, please refer to Figure 4 The central axis of the striking port 11a intersects with the central axis of the striking pin 122.

[0038] like Figure 4 As shown, the central axis of the striking port 11a is represented by d.

[0039] In the locked state, the central axis of the striking port 11a intersects the central axis of the striking pin 122. Thus, without the need for additional structures, the interaction between the drive unit 13 and the striking pin 122 can selectively lock or unlock the striking pin 122, making the structure of the safety hammer 10 simpler.

[0040] In some embodiments, please refer to Figure 4 and Figure 5 The outer ring of the firing pin 122 is provided with a second limiting part 122b, and the housing 11 is provided with a first limiting part 11c. The second limiting part 122b has a first abutting surface 122a, the first limiting part 11c has a second abutting surface 11e, and the driving member 13 has a third abutting surface 13b. In the locked state, the second limiting part 122b abuts against the third abutting surface 13b.

[0041] Specifically, a first contact surface 122a is formed on the side of the second limiting part 122b near the striking port 11a, and a second contact surface 11e is formed on the side of the first limiting part 11c away from the striking port 11a along the first direction. That is, the contact direction of the first cross section and the second contact surface 11e is approximately the same as or exactly the same as the first direction. In this way, when the driving member 13 moves along the first direction, it is beneficial for the driving member 13 to push the first elastic member 121 to compress in the first direction, and make the direction of the elastic potential energy stored in the first elastic member 121 approximately toward the striking port 11a, which is beneficial for the striking of the striking pin 122.

[0042] Here, by providing a third abutment surface 13b in the drive member 13, the third abutment surface 13b abuts against the second limiting part 122b of the outer ring of the striker 122 in the locked state, which is beneficial to the fixation of the striker 122 in the locked state and improves the reliability of locking the striker 122.

[0043] In some embodiments, please refer to Figure 4 and Figure 5 The driving member 13 is provided with a first limiting protrusion 13c, and the first elastic member 121 is sleeved on the firing pin 122, with its two ends respectively abutting against the first limiting protrusion 13c and the end of the second limiting part 122b away from the first abutting surface 122a.

[0044] Here, the first limiting protrusion 13c can be provided at the end of the drive member 13 away from the striking port 11a along the first direction. The second limiting part 122b can be fixedly connected to the striking pin 122.

[0045] By abutting the two ends of the first elastic member 121 against the first limiting protrusion 13c and the end of the second limiting part 122b away from the first abutting surface 122a, and with the second limiting part 122b abutting against the first limiting part 11c in the locked state, it is beneficial for the driving member 13 to compress the first elastic member 121 through the first limiting protrusion 13c during the movement of the driving member 13 toward the striking port 11a in the first direction, thereby improving the stability of the compression of the first elastic member 121.

[0046] In some embodiments, please refer to Figure 4 and Figure 5 The firing pin 122 has a second limiting protrusion 122c protruding from one end away from the striking port 11a. The second limiting protrusion 122c is located on the side of the first limiting protrusion 13c away from the first elastic member 121, and the second limiting protrusion 122c can abut against the first limiting protrusion 13c.

[0047] The first limiting protrusion 13c can define the through hole 13d. The end of the striker 122 away from the second limiting part 122b passes through the through hole 13d. The second limiting protrusion 122c is provided on the side of the first limiting protrusion 13c away from the first elastic member 121. In this way, when the drive member 13 moves away from the striking port 11a in the first direction, the first limiting protrusion 13c can drive the striker 122 to retract into the striking port 11a by limiting and abutting with the second limiting protrusion 122c.

[0048] In some embodiments, please refer to Figures 1 to 6 The safety hammer 10 also includes a cutting device 15, and the housing 11 has a notch 11b, the cutting device 15 being configured to extend out of the housing 11 through the notch 11b.

[0049] Here, the portion of the housing 11 outside the notch 11b defines the cutting space. The cutting device 15 extends out of the housing 11 through the notch 11b and is located within the cutting space. Thus, the object to be cut needs to extend into the cutting space to contact the cutting device 15, which can improve the situation of accidental contact with the cutting device 15 and reduce the probability of accidentally cutting the user. In addition, no additional operation is required during cutting, making it more convenient to use in emergency situations, such as cutting seat belts in an emergency.

[0050] For example, the cutting device 15 can be a blade.

[0051] For example, the cutting device 15 is fixedly connected to the housing 11.

[0052] In some embodiments, please refer to Figure 1, Figures 4 to 6 The safety hammer 10 also includes a lighting device 16, which is disposed in the housing 11.

[0053] In this embodiment, the lighting device 16 can have its lighting portion exposed within the housing 11, thereby enabling illumination. Alternatively, the lighting device 16 can be disposed within the housing 11, with the housing 11 having a lighting hole communicating with the interior of the housing 11, allowing light emitted by the lighting device 16 to exit the housing 11 through the lighting hole. Exemplarily, in another embodiment, the lighting device 16 can emit flashing light, achieving the effect of a rescue light.

[0054] In some embodiments, the safety hammer 10 includes a cutting device 15 and a lighting device 16. By integrating the cutting device 15 and the lighting device 16 into the safety hammer 10, the functions of striking, cutting objects, and lighting are realized, making it a three-in-one multi-functional safety hammer. This makes it suitable for various usage scenarios and meets the diverse needs of users.

[0055] In some embodiments, please refer to Figure 4 and Figure 5 The safety hammer 10 also includes a second elastic element 20, which is connected between the drive element 13 and the housing 11 and is used to drive the spring pin assembly 12 from the firing state to the locking state.

[0056] When the trigger 14 is released, the second elastic element 20 is configured to drive the drive element 13 to reset. Through the cooperation between the drive element 13 and the sliding part 141, specifically the sliding cooperation between the slide groove 13a and the slider, the trigger 14 is indirectly reset. At the same time, the drive element 13 pulls the firing pin 122 back into the housing 11 from the outside by limiting the first limiting protrusion 13c and the second limiting protrusion 122c of the firing pin 122 until the second limiting part 122b of the firing pin 122 passes the second abutment surface 11e on the housing 11 and contacts the third abutment surface 13b on the drive element 13. That is, the spring pin assembly 12 switches to the locked state.

[0057] For example, the second elastic element 20 is a spring.

[0058] In some embodiments, the safety hammer 10 does not have a second elastic element 20. The user can manually drive the trigger 14 to reset it, and through the cooperation between the drive element 13 and the sliding part 141, the drive element 13 is driven to reset. The drive element 13, through the limitation between the first limiting protrusion 13c and the second limiting protrusion 122c of the firing pin 122, pulls the firing pin 122 back from the outside into the housing 11 and locks the firing pin 122 in the housing 11, thereby realizing the reset of the firing pin 122.

[0059] In some embodiments, please refer to Figures 1 to 7The safety hammer 10 also includes a battery 17. The trigger 14 has a receiving groove 14a. At least a portion of the battery 17 is disposed within the receiving groove 14a.

[0060] Here, battery 17 is used to power the lighting module.

[0061] At least a portion of the battery 17 is disposed within the receiving groove 14a, including the battery 17 being completely disposed within the receiving groove 14a, or the battery 17 being partially disposed within the receiving groove 14a.

[0062] Specifically, the opening direction of the receiving groove 14a of the trigger 14 is towards the inside of the housing 11 along the pressing direction of the trigger 14.

[0063] In this embodiment, at least a portion of the battery 17 is disposed within the receiving groove 14a formed by the trigger 14. On the one hand, this can provide a counterweight to the trigger 14 and improve the feel of pressing the trigger 14; on the other hand, it can reduce the space occupied by the battery 17 in the housing 11, which is beneficial to the miniaturization design of the safety hammer 10.

[0064] In some embodiments, the safety hammer 10 is also provided with a button 19 on the housing 11 for switching the lighting device 16 on and off, and for switching the usage mode of the lighting device 16. For example, switching the light of the lighting device 16 to flash or remain constantly on.

[0065] In some embodiments, the housing 11 is also provided with a charging port 11d. The charging port 11d is used to charge the battery 17.

[0066] In some embodiments, please refer to Figures 1 to 6 The housing 11 includes a grip housing 111 and a barrel housing 112. The grip housing 111 and the barrel housing 112 are connected. The cartridge pin assembly 12 is located inside the barrel housing 112. A portion of the trigger 14 is located inside the grip housing 111. The grip housing 111 has an extension opening 111a. The end of the trigger 14 away from the cartridge pin assembly 12 can extend or retract into the housing 11 through the extension opening 111a.

[0067] The barrel housing 112 extends along the sliding direction of the drive member 13.

[0068] The extension direction of the grip cover 111 intersects the extension direction of the barrel cover 112, which can be perpendicular or not perpendicular.

[0069] The fact that part of the trigger 14 is located inside the grip housing 111 means that the trigger 14 is set on the grip housing 111. Specifically, it can mean that part of the trigger 14 is set inside the grip housing 111 and part of the trigger 14 is outside the grip housing 111.

[0070] The gun handle housing 111 has an extension opening 111a. For example, the opening direction of the extension opening 111a is parallel to the sliding direction of the drive member 13.

[0071] This reduces the distance between the trigger 14 and the grip shell 111, making it easier for the user to press the trigger 14 when holding the grip shell 111. It also makes it easier to apply more force to the trigger 14, which is beneficial for users with small hands to trigger the trigger 14.

[0072] In some embodiments, please refer to Figures 1 to 6 The housing 11 also includes a sleeve 113. The barrel housing 112 and the handle housing 111 are divided into at least two separate housings.

[0073] This facilitates assembly. The barrel housing 112 and the handle housing 111 on the separate casing are integrally formed. The barrel housing 112 has an external thread at the end near the striking port 11a. The sleeve 113 has an internal thread. The internal thread mates with the external thread to fix the separate casing and improve the structural strength of the barrel housing 112 near the striking port 11a.

[0074] In some embodiments, please refer to Figures 1 to 6 The safety hammer 10 also includes an end cap 18. The end cap 18 is located at the end of the barrel housing 112 away from the sleeve 113.

[0075] In the description of this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application.
