Description

Technical Field

[0001] This invention relates to the field of manual marking technology, and more particularly to bolt anti-loosening marking stamps. Background Technology

[0002] Currently, in industrial production, rail transportation, and machinery equipment, the marking of bolts after tightening is typically done manually using a traditional method. The specific procedure is as follows: The operator first tightens the bolt to the specified torque using a torque wrench or similar tool, ensuring the bolt is properly secured. Then, holding a marker (usually an oil-based or paint-based marker), the operator manually draws a straight line at the junction of the bolt head and nut, based on their experience. This straight line is used to detect bolt loosening later. If the bolt is loose, relative rotation between the bolt head and nut will cause the manually drawn line to break or misalign, quickly indicating an abnormal bolt tightening condition. This method requires only a marker and is widely used in various bolt anti-loosening marking scenarios, especially in simple scenarios such as small equipment assembly and temporary maintenance.

[0003] However, manual marking has the following disadvantages: (1) Extremely low work efficiency: When an operator completes the marking of a single bolt, he / she must first align the connection position of the bolt and nut, and then slowly draw a straight line. During the operation, he / she must deliberately control the stability of his / her hand to avoid the marking line deviation, which greatly increases the workload of the operator. (2) Poor marking accuracy and inability to guarantee straightness: Manual marking relies entirely on the operator's experience and hand stability. Affected by factors such as hand tremors, line deviation, and operating posture, the drawn straight line is prone to bending, tilting, and deviation, and cannot accurately fit the connection between the bolt head and the nut. In some cases, the marking line may even cross the connection or not cover the connection, affecting the accuracy of subsequent bolt loosening detection. (3) Extremely poor marking consistency: Different operators have different operating habits, marking force, and marking speed. Even for the same operator, hand fatigue after long-term operation will lead to unstable marking status, resulting in inconsistent thickness, depth, and position of the marking lines of a batch of bolts. It is impossible to form a unified marking standard, which is not conducive to subsequent quality inspection, patrol inspection, and standardized management. (4) High operating threshold and low error tolerance: Manual marking requires operators to have certain operating experience and to be proficient in marking position, force and speed. Novice operators are prone to marking mistakes, which require repeated erasing and redrawing, further reducing work efficiency. At the same time, markers are prone to ink leakage and ink breakage, resulting in discontinuous marking and affecting the marking effect. Furthermore, the wiping process can easily contaminate the bolt surface, affecting the bolt's rust prevention performance and appearance quality.

[0004] Chinese patent document CN223337646U discloses a large bolt anti-loosening marking and coating device for railway vehicles, which can improve the marking quality and consistency to a certain extent by cooperating with the elastic air bladder and the coating gap. However, its use requires first applying marking oil to the elastic air bladder through the brush assembly, and then operating the push handle to make the elastic air bladder apply the marking to the bolt, which is cumbersome; in addition, the structure of the device is also relatively complex. Summary of the Invention

[0005] To solve the above problems, the present invention provides a bolt anti-loosening marking stamp, which is achieved through the following technical solution:

[0006] The bolt anti-loosening marking stamp provided in this application includes a housing, an impact pin mounted on the housing, a rocker arm rotatably connected to the housing via a shaft, an ink storage assembly mounted on the housing, and a reset component. The impact pin can respond to external forces and generate a trigger displacement, which drives the rocker arm to rotate. The rocker arm converts the trigger displacement of the impact pin into a marking action of the ink storage assembly. The ink storage assembly includes an ink cartridge and ink-retaining cotton mounted on the ink cartridge. The ink-retaining cotton is configured to contact the fastener to apply a mark to the fastener. When the impact pin generates the trigger displacement, the rocker arm rotates around the shaft, and the ink storage assembly moves downward. Under the action of the reset component, the rocker arm, the ink storage assembly, and the impact pin reset. This application is based on pressure triggering and lever transmission. Through the coordinated cooperation of the impact pin and the rocker arm, external forces (such as the user's pressing action) can be converted into precise marking actions of the ink storage assembly, achieving rapid marking operations. The reset component enables automatic reset of each component after marking, improving work continuity, further enhancing work efficiency, and simplifying the operation process.

[0007] Preferably, the impact pin, rocker plate, and ink storage assembly are housed within a housing, which has an impact pin hole. Under the action of the reset member, one end of the impact pin extends out of the housing through the impact pin hole.

[0008] Optionally, the lower end of the housing has a lower opening configured to position a fastener and allow at least a portion of the fastener to enter the housing.

[0009] Optionally, the ink reservoir can be detachably connected to the ink cartridge.

[0010] Furthermore, the housing has a first guide member that guides the impact pin to move along the housing.

[0011] Preferably, the housing has a second guide member and / or a third guide member, which guide the ink storage assembly to move along the housing toward the fastener. The second guide member and / or the third guide member provide precise guidance for the ink storage assembly, restrict the movement trajectory of the ink storage assembly, ensure that the ink storage cotton accurately contacts the bolt / nut connection, and guarantee the straightness and consistency of the markings.

[0012] The rocker arm is divided into two sections by an axis: section A and section B. The upper end of the ink storage assembly is movably connected to section B of the rocker arm. The upper end of the impact pin is configured to contact or connect with section A of the rocker arm, and the lower end of the impact pin extends outside the housing.

[0013] Optionally, the ink storage assembly also includes an ink cartridge holder, the upper end of which is movably connected to a rocker plate, and the ink cartridge is detachably mounted on the ink cartridge holder.

[0014] Preferably, the ink cartridge holder has a mounting position adapted to the ink cartridge, the mounting position allowing the ink cartridge to be inserted upwards and removed downwards.

[0015] Furthermore, the ink cartridge has a force-applying part configured to allow the user to apply force to push the ink cartridge downward from the mounting position.

[0016] Optionally, the side wall of the housing has an operating notch corresponding to the position of the force application part, and the force application part is exposed from the operating notch. When the ink cartridge is removed from the ink cartridge, the ink cartridge can be removed from the lower opening at the bottom of the housing.

[0017] Furthermore, the ink cartridge holder has a fourth guide member that guides the ink cartridge into the mounting position.

[0018] Optionally, the fourth guiding member is a third guiding groove formed on the ink cartridge holder, and the ink cartridge has a third guiding block that matches the third guiding groove. Preferably, the lower opening of the third guiding groove is enlarged to form a wedge-shaped opening, so as to guide the third guiding block to slide into the third guiding groove.

[0019] Furthermore, a second limiting structure is provided between the ink cartridge holder and the ink cartridge. The second limiting structure includes a second limiting protrusion and a second limiting groove that matches the second limiting protrusion. One of the second limiting protrusion and the second limiting groove is disposed on the ink cartridge holder, and the other is disposed on the ink cartridge. When the ink cartridge is installed in the mounting position, the second limiting protrusion is inserted into the second limiting groove.

[0020] Optionally, the housing includes a front housing and a rear housing, which are joined together to form a housing, and the front housing and the rear housing are detachably connected together.

[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] 1. This application is easy to operate and simplifies the operation process. Operators only need to align the stamp with the connection position between the bolt head and the nut and press it gently to the bottom to quickly complete the marking operation, which greatly improves the efficiency of batch bolt marking, reduces the workload of operators, and is suitable for large-scale, assembly line production needs.

[0023] 2. This application has strong stability and significantly improves marking accuracy and straightness: Through the coordinated operation of the impact pin, rocker plate, rotating shaft and guide, it can ensure that the ink storage cotton always moves along a fixed trajectory. The lines marked each time are straight and accurately fit the surface of the fastener, avoiding problems such as bending, tilting and offset. This greatly improves the accuracy of subsequent bolt loosening detection and reduces the risk of misjudgment caused by marking deviation.

[0024] 3. This application can achieve standardization and consistency of marking: the trigger displacement of the impact pin can limit the rotation amplitude of the rocker, and the rotation amplitude of the rocker can constrain the marking stroke of the ink storage cotton, which can realize the uniformity of the marking displacement of the ink storage cotton each time, ensuring that the line thickness of each mark is uniform, the depth is consistent, and the position is consistent, eliminating the marking differences caused by different operators and different operating postures, forming standardized anti-loosening marks, which facilitates subsequent quality inspection, patrol inspection and standardized management, and improves the overall quality of product assembly.

[0025] 4. This application can lower the operating threshold and increase the error tolerance: the operation process is simple and no operator needs to have rich operating experience. Novices can get started quickly and avoid the problem of errors when manually drawing lines. At the same time, the elastic design of the ink storage cotton can adapt to the surface curvature of bolts / nuts of different specifications, the ink is released evenly, avoids ink leakage and ink interruption, prevents contamination of the bolt surface, ensures the rust prevention performance and appearance quality of the bolts, and reduces the rework rate.

[0026] 5. This application features a simple structure, strong practicality, and convenient maintenance: the machine has few parts and a compact structure, which facilitates processing, assembly, and mass production, resulting in low production costs; the ink storage box is detachable, making it easy to replace and replenish ink, and the ink storage cotton can be replaced separately, extending the service life of the machine and reducing maintenance costs; the handheld portable design makes it easy for operators to carry and is suitable for use in various scenarios such as workshops and construction sites.

[0027] Of course, implementing any of the embodiments of the present invention does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The bolt anti-loosening marking stamp disclosed in this embodiment belongs to the category of mechanical hand tools, and its overall structure is handheld and portable. Please refer to... Figures 1 to 3 A preferred bolt anti-loosening marking stamp includes a housing 1, a transmission assembly 2, an ink storage assembly 3, and a reset component 4. The transmission assembly 2 converts external forces (such as operational pressure) into marking actions on the ink storage assembly 3. The reset component 4 resets the ink storage assembly 3 to its initial position for the next marking. Through the coordinated operation of the transmission assembly 2, the ink storage assembly 3, and the reset component 4, fastener anti-loosening marking can be performed quickly, accurately, and in a standardized manner. It features a simple structure, convenient operation, and strong stability.

[0041] Please see Figure 3 The transmission assembly 2 includes an impact pin 21 and a rocker arm 22. The rocker arm 22 is rotatably connected to the housing 1 via a shaft 23. The rocker arm 22 forms a lever structure with the shaft 23 as its center; the rocker arm 22 can rotate with the shaft 23 as its center. The impact pin 21 is configured to respond to the user's pressing action and can move with the pressing action. The rocker arm 22 can convert the movement of the impact pin 21 into the movement of the ink storage assembly 3. Of course, in the initial state, a part of the impact pin 21 is exposed to the outside of the housing 1 to bear external forces.

[0042] Please see Figure 3 and Figure 4In the exemplary embodiment, the impact pin 21 and the ink storage assembly 3 are located at opposite ends of the rocker 22. Specifically, the rocker 22 is divided into two sections by the shaft 23: section A 221 and section B 222. The upper end of the impact pin 21 is configured to contact or connect with section A 221 of the rocker 22, and the lower end of the impact pin 21 is a receiving end 210, which is used to receive external forces. The ink storage assembly 3 is movably connected to section B 222 of the rocker 22. In the initial state, under the action of the reset member 4, the receiving end 210 of the impact pin 21 extends downward from the impact pin hole 17 of the housing 1 to the outside of the housing 1, and the ink storage assembly 3 is in a non-operating position. When the exposed impact pin 21 is pressed back, the impact pin 21 can push section A 221 of the rocker 22 upward, while section B 222 of the rocker 22 presses downward accordingly, simultaneously driving the ink storage assembly 3 downward to the operating position to complete the marking operation. After the operation is completed, the impact pin 21 loses pressure, and under the action of the reset component 4, the rocker plate 22, the ink storage assembly 3 and the impact pin 21 are reset.

[0043] The reset element 4 is a mechanical part made of an elastic material that can deform under external force and return to its original shape. For example, it can be a metallic elastic element such as a coil spring, or a non-metallic elastic element such as a rubber part. In an exemplary embodiment, the reset element 4 is a coil spring, and the B segment 222 of the rocker 22 has an upward-facing spring post 223. The coil spring is sleeved on the spring post 223, the lower end of the coil spring acts on the rocker 22, and the upper end of the coil spring acts on the housing 1.

[0044] It is worth noting that the installation position of the reset member 4 can be reasonably set by those skilled in the art as needed. In an exemplary embodiment, the reset member 4 acts on segment B 222 of the rocker 22 to press segment B 222 of the rocker 22 down. In other embodiments, the reset member 4 acts on segment A 221 of the rocker 22 to raise segment A 221 of the rocker 22, or the reset member 4 acts on the impact pin 21, or on the ink storage assembly 3. The reset member 4 can also be configured for the rocker 22, the ink storage assembly 3, and the impact pin 21 respectively. In summary, this application does not limit the installation position and setting method of the reset member 4.

[0045] It is worth noting that the impact pin 21 may or may not be connected to the rocker arm 22. When the impact pin 21 is not connected to the rocker arm 22, to prevent the impact pin 21 from leaving the housing 1 through the impact pin hole 17, a first limiting structure is provided on the housing 1 to restrict the impact pin 21. The first limiting structure includes a first limiting part 211 provided on the impact pin 21 and a second limiting part 18 provided on the housing 1. The first limiting part 211 is higher than the second limiting part 18. When the first limiting part 211 moves downward to abut against the second limiting part 18, the impact pin 21 cannot move downward relative to the housing 1. In an exemplary embodiment, the first limiting part 211 is a protrusion formed on the surface of the impact pin 21, and the second limiting part 18 is a protrusion formed on the inner surface of the housing 1.

[0046] To make the movement of the impact pin 21 more stable, in some embodiments, the housing 1 has a first guide member, which is a member for guiding the impact pin 21 to move up and down along the housing 1. It is worth noting that the first guide member can be any common form and structure, such as a longitudinal groove 13 formed on the housing 1 for a portion of the impact pin 21 to slide.

[0047] To make the movement of the ink storage assembly 3 more stable, in some embodiments, the housing 1 has a second guide member, which is a member for guiding the movement of the ink storage assembly 3. It is worth noting that the second guide member can be any common form and structure, such as a first guide groove 14 formed on the housing 1 for a portion of the ink storage assembly 3 to slide.

[0048] To make the marking action of the ink storage assembly 3 more stable, the housing 1 has a third guide member, which is also a member used to guide the movement of the ink storage assembly 3. It is worth noting that the third guide member can be any common form and structure, such as a second guide groove 15 formed on the housing 1 for a part of the ink storage assembly 3 to slide.

[0049] Preferably, the first guide groove 14 is higher than the second guide groove 15, and the first guide groove 14 is closer to the rocker plate 22. The first guide groove 14 is an arc-shaped groove to guide the ink storage assembly 3 to move toward the fastener. The second guide groove 15 is a straight groove, which allows the ink storage cotton to fit more tightly with the fastener during use.

[0050] It should be understood that the maximum displacement of the impact pin 21 caused by inward pressure is equivalent to its length protruding from the housing 1; once the impact pin 21 is completely pressed into the housing 1, it no longer has the capacity to withstand external forces. The maximum displacement of the impact pin 21 should be greater than the trigger displacement to ensure that the ink storage assembly 3 can move to the working position to complete the marking.

[0051] It is worth noting that the stroke of the ink storage component 3 can be controlled by the impact pin 21. For example, the maximum displacement of the impact pin 21 can be used as its trigger displacement, ensuring a constant trigger stroke each time. This simplifies operation and guarantees a uniform length of the marking line obtained each time. The stroke of the ink storage component 3 can also be controlled by a limiting structure between the ink storage component 3 and the housing 1. For example, in some embodiments, the limiting structure is a component that restricts the stroke of the ink storage component 3. It is worth noting that the limiting structure can be any common form and structure, such as a first guide groove 14 and / or a second guide groove 15 formed on the housing 1 for a portion of the ink storage component 3 to slide. The first guide groove 14 and the second guide groove 15 both limit the movement path and limit the stroke. Under the action of the limiting structure, the uniform length of the marking line obtained each time can be guaranteed. In some embodiments, the maximum displacement of the impact pin 21 is its trigger displacement, and with a limiting structure between the ink storage component 3 and the housing 1, the stroke of the ink storage component 3 can also be controlled by both the limiting structure and the maximum displacement of the impact pin 21.

[0052] Please see Figures 5 to 7 The ink storage assembly 3 includes an ink cartridge holder 31, an ink cartridge 32, and an ink-retaining cotton 33 inside the ink cartridge 32. The upper end of the ink cartridge holder 31 is connected to section B 222 of the rocker 22, and the ink cartridge 32 is detachably mounted on the ink cartridge holder 31. The ink-retaining cotton 33 has good elasticity and ink absorption. The ink-retaining cotton 33 absorbs ink and has a contact surface 331 for contacting fasteners. After the contact surface 331 is pressed into contact with the fastener, it can leave a continuous mark on the surface of the fastener.

[0053] In some embodiments, the upper end of the ink cartridge holder 31 is hinged to segment B 222 of the rocker 22. The ink cartridge holder 31 has a first guide block 34 that matches the first guide groove 14 and a second guide block 35 that matches the second guide groove 15. The first guide block 34 is installed in the first guide groove 14 and the second guide block 35 is installed in the second guide groove 15. The first guide groove 14 and the second guide groove 15 can guide the movement direction of the ink storage assembly 3 and limit the stroke of the ink storage assembly 3.

[0054] As described above, the housing 1 has a first guide groove 14 and a second guide groove 15, and the cartridge holder 31 has a first guide block 34 and a second guide block 35. However, this application is not limited to this. For example, in some embodiments, the housing 1 has a first guide block 34 and a second guide block 35, and the cartridge holder 31 has a matching first guide groove 14 and a second guide groove 15. In other embodiments, the housing 1 has a first guide block 34 and a second guide groove 15, and the cartridge holder 31 has a matching first guide groove 14 and a second guide block 35.

[0055] In an exemplary embodiment, two pins are installed in mounting holes respectively installed in the ink cartridge holder 31. Both ends of the pins extend outside the mounting holes, thus forming a first guide block 34 and a second guide block 35 on the left and right sides of the ink cartridge holder 31. The middle section of the pin at the higher position is installed in the corresponding shaft hole of the rocker arm 22, achieving a hinge connection between the ink cartridge holder 31 and the rocker arm 22. This design simplifies the overall structure and makes the device more concise.

[0056] For ease of replacement and maintenance, the ink cartridge is designed to be detachable, facilitating ink replacement and refilling. The cartridge holder 31 is provided with a mounting position 310 that mates with the ink cartridge 32. In an exemplary embodiment, the mounting position 310 allows the ink cartridge 32 to be inserted upwards and removed downwards.

[0057] To facilitate the installation and securing of the ink cartridge 32, in some embodiments, the ink cartridge holder 31 has a fourth guiding member, which is used to guide the ink cartridge 32 into the ink cartridge holder 31. It is worth noting that the fourth guiding member can be any common form and structure, such as a third guide groove 311 formed on the ink cartridge holder 31 for a portion of the ink cartridge 32 to slide. Correspondingly, the ink cartridge 32 has a third guide block 321 that matches the third guide groove 311. When the ink cartridge 32 needs to be installed, the third guide block 321 moves upward into the third guide groove 311 to guide the ink cartridge 32 to the mounting position 310. The third guide groove 311 guides the upward insertion of the ink cartridge 32 and also restricts the left-right wobbling of the ink cartridge 32.

[0058] To facilitate the sliding of the third guide block 321, the lower opening of the third guide groove 311 is enlarged to form a wedge-shaped opening 312. The wedge-shaped opening 312 facilitates the smooth sliding of the third guide block 321 into the third guide groove 311, making it easier to install the ink cartridge 32 into the mounting position 310.

[0059] To further prevent the ink cartridge 32 from accidentally detaching downwards, a second limiting structure is provided between the ink cartridge holder 31 and the ink cartridge 32. The second limiting structure includes a second limiting protrusion 322 and a second limiting groove 313 that matches the second limiting protrusion 322. One of the second limiting protrusion 322 and the second limiting groove 313 is disposed on the ink cartridge holder 31, and the other is disposed on the ink cartridge 32. When the ink cartridge 32 is installed in the mounting position 310, the second limiting protrusion 322 is inserted into the second limiting groove 313, preventing the ink cartridge 32 from accidentally detaching downwards. In an exemplary embodiment, the second limiting groove 313 is formed on the groove wall of the third guide groove 311, and the second limiting protrusion 322 is formed on the surface of the third guide block 321.

[0060] To facilitate removal of the ink cartridge 32 from the ink cartridge holder 31, the ink cartridge 32 is provided with a force-applying part 323, which is configured to allow the user to apply force to the ink cartridge 32. In some embodiments, under normal conditions, after the ink cartridge 32 is assembled into the preset mounting position 310 of the ink cartridge holder 31, it is completely stored inside the housing 1. An operation notch 16 is provided on the side wall of the housing 1 corresponding to the force-applying part 323, and the force-applying part 323 is exposed through the operation notch 16, facilitating manual operation from the outside. When the ink cartridge 32 needs to be removed, the user applies force to the application part 323 with their finger or other tool through the operation notch 16, and then pulls the ink cartridge 32 downwards. This causes the second limiting protrusion 322 to disengage from the second limiting groove 313, and the ink cartridge 32 to move downwards until it leaves the ink cartridge holder 31. Then, the ink cartridge 32 can be removed from the lower opening 10 of the housing 1. When the ink cartridge 32 needs to be reinstalled, the user pushes the ink cartridge 32 upwards along the inner side of the housing 1. The fourth guide member guides the ink cartridge 32 to slide into the ink cartridge holder 31. When the second limiting protrusion 322 enters the second limiting groove 313, the ink cartridge 32 is installed in place.

[0061] It is worth noting that the force-applying part 323 can be any common form and structure. For example, the force-applying part 323 can be a protrusion and / or a groove formed on the ink cartridge 32. When the force-applying part 323 is a protrusion, optionally, there is a slot 314 on the ink cartridge holder 31 that is adapted to the force-applying part 323. When the ink cartridge 32 is installed in the mounting position 310, the force-applying part 323 enters the slot 314.

[0062] In some embodiments, the ink reservoir 33 is detachable, allowing for individual replacement and extending the overall lifespan of the ink cartridge. The implementation and structure of the detachable ink reservoir 33 are not limited in this application; those skilled in the art can design it appropriately as needed. In some embodiments, the ink cartridge 32 has a groove for holding the ink reservoir 33, with a portion of the ink reservoir 33 housed within the groove. Furthermore, the ink reservoir 33 has an opening with a post, which is detachably connected to the ink cartridge 32.

[0063] For ease of assembly, in an exemplary embodiment, the housing 1 includes a front housing 11 and a rear housing 12, which are joined together to form the housing 1. The front housing 11 and the rear housing 12 can be connected together by multiple connectors 19, or they can be connected by snap-fit ​​connections, which can be reasonably configured as needed by those skilled in the art. The connectors 19 can be any connectors such as screws or rivets, and this application does not impose any restrictions.

[0064] During assembly, after installing the transmission component 2, ink storage component 3 and reset component 4 inside the rear housing 12 according to the above positional and connection relationships, the front housing 11 is placed over the rear housing 12. The front housing 11 and the rear housing 12 are then fixedly connected with the connector 19 to ensure a firm and secure connection without loosening, thus forming a bolt anti-loosening mark stamp, and the assembly is ready for use.

[0065] The impact pin 21, as the starting component, is the core of realizing the "press-trigger" action. It replaces the manual holding of the marker pen in the existing technology, transforms the pressing action into the movement of the rocker 22, provides power for subsequent transmission, ensures convenient operation, and solves the problems of low efficiency and cumbersome operation of manual drawing.

[0066] The rocker arm 22 and shaft 23 form a lever transmission structure, which is the core of power transmission. It converts the motion of the impact pin 21 into a downward driving force for the ink storage assembly 3, ensuring that the ink storage cotton 333 can accurately and stably contact the surface of the bolt / nut, thus solving the problems of poor accuracy and insufficient straightness in manual scribing. By guiding the movement trajectory of the ink storage assembly 3, it ensures that the ink storage cotton 33 always moves in the vertical direction, avoiding deviation. At the same time, it provides a stable mounting carrier for the ink storage box 32, ensuring that the position and angle of each mark are consistent, thus solving the problem of poor consistency in manual scribing.

[0067] Ink reservoir 33 possesses excellent ink absorption and release properties, ensuring even ink distribution and preventing ink leakage or interruptions. It also solves the problems of inconsistent line thickness and easy contamination of bolts when manually scribing lines. Ink reservoir 33 also has good elasticity, allowing it to adapt to the surfaces of bolts of different sizes.

[0068] The trigger displacement of the impact pin 21 limits the rotation amplitude of the rocker arm 22, and the rotation amplitude of the rocker arm 22 constrains the marking stroke of the ink storage cotton 33, thereby achieving stable and reliable marking operations. The reset component 4 enables the entire machine to reset, ensuring that all components quickly return to their initial state after marking, improving work continuity, further enhancing work efficiency, and solving the problem of repeated posture adjustments and low efficiency in manual marking. The transmission component 2 and the ink storage component 3 are housed in the housing 1, which has a lower opening 10 at its lower end. The lower opening 10 is configured to position the fastener and allows at least a portion of the fastener to enter the interior of the housing 1. In use, the lower opening 10 at the bottom of the bolt anti-loosening marking stamp is aligned with the bolt to perform the marking operation. Of course, the size of the lower opening 10 matches the bolt specification; by replacing different models of bolt anti-loosening marking stamps to adapt to different bolt specifications, the marking needs of different scenarios can be met.

[0069] In this embodiment, the preferred bolt anti-loosening marking stamp operates in two stages: "marking action" and "resetting action." The specific operating principle is as follows:

[0070] I. Marking process

[0071] a. Initial state: The reset member 4 is in a naturally extended state, pressing down the A section 221 of the rocker 22, causing the impact pin 21 to extend downward along the housing 1, so that the receiving end 210 of the impact pin 21 is exposed outside the housing 1; the B section 222 of the rocker 22 is in an upward lifted state, driving the ink storage assembly 3 to a high position; the first guide block 34 and the second guide block 35 are respectively located at the top of the first guide groove 14 and the second guide groove 15 of the housing 1, and the entire device is in a state to be marked.

[0072] b. Triggering and Transmission Process: After tightening the bolt torque, the operator holds the housing 1 with one hand, aligns the lower opening 10 of the bolt anti-loosening mark with the bolt, and then presses the bolt anti-loosening mark down to the bottom, causing the impact pin 21 to be pushed back. During this process, the bolt anti-loosening mark moves downward as a whole, and the receiving end 210 of the impact pin 21 is pressed first. As the bolt anti-loosening mark moves downward, the impact pin 21 is subjected to a reaction force and moves upward relative to the housing 1. The tip of the impact pin 21 precisely strikes or pushes the A section 221 of the rocker plate 22. When the impact pin 21 strikes or pushes the A section 221 of the rocker plate 22 upward, the A section 221 is subjected to an upward force, overcoming the elastic force of the reset member 4 and compressing the reset member 4; at the same time, the rocker plate 22 rotates around the axis 23, and the B section 222 of the rocker plate 22 rotates downward.

[0073] c. Movement and marking of ink storage assembly 3: Since the ink cartridge holder 31 is connected to segment B 222, the downward movement of segment B 222 drives the ink cartridge holder 31 to move downward synchronously. During this process, the first guide block 34 and the second guide block 35 on the ink cartridge holder 31 slide along the first guide groove 14 and the second guide groove 15 of the housing 1, respectively, restricting the movement trajectory of the ink cartridge holder 31 and ensuring that it always moves downward along the guide groove without deviation or tilting.

[0074] When the ink cartridge holder 31 moves downward, it drives the ink reservoir 32 and ink reservoir cotton 33 to move downward simultaneously until the ink reservoir cotton 33 makes tight contact with the bolt, nut, and washer. The ink reservoir cotton 33 is squeezed by the surface of the fastener, which squeezes out the ink absorbed inside evenly. The ink adheres to the surface of the fastener, forming a continuous, clear, and uniform mark, thus completing the anti-loosening marking operation of the bolt.

[0075] II. Reset Process: After marking is completed, the operator lifts the bolt anti-loosening marking stamp, and the impact pin 21 is lifted away. At this time, the compressed reset component 4 releases its elastic restoring force, pressing down on section A 221 of the rocker plate 22, causing section A 221 of the rocker plate 221 to reset downwards, driving the impact pin 21 to move downwards along the housing 1 and return to its initial extended state; at the same time, section B 222 of the rocker plate 22 rotates upwards, driving the ink storage assembly 3 to move upwards, and the first guide block 34 and the second guide block 35 slide upwards along the first guide groove 14 and the second guide groove 15 of the housing 1, returning to their initial high position; the entire device is reset and can be used for the next marking operation.

[0076] As described above, during triggering and transmission, the reset member 4 is compressed to store elastic force. However, this application is not limited to this. In other embodiments, during triggering and transmission, the reset member 4 is stretched to store elastic force, or twisted to store elastic force, or any other deformation mode.

[0077] This invention adopts a single-handed pressing operation, eliminating the need for operators to manually draw straight lines. Simply align the bolt and press gently to complete the marking. It can effectively adapt to the large-scale, assembly-line production needs of batch bolt fastening marking, significantly reducing the workload of operators and reducing labor costs.

[0078] This application features a simple structure with few and compact components, facilitating processing, assembly, and mass production, thus reducing production costs. The entire process of alignment, pressing, marking, and resetting can be completed with a single hand, eliminating the need for complex operations and lowering the operational threshold. Furthermore, this application uses guiding components and other structural elements to restrict the movement trajectory of parts, ensuring precise transmission and stable marking, and preventing problems such as jamming or misalignment.
