Description

Technical Field

[0001] This utility model relates to the field of nail gun technology, and in particular to an anti-air-firing component, an anti-air-firing device, and a nail gun. Background Technology

[0002] Currently, nail guns on the market are designed to prevent operators from failing to notice when the nails are almost used up, which could lead to the firing pin being fired and causing injury to the operator and those around them. To avoid the problem of dry-firing, existing technology equips nail guns with anti-dry-firing components. These components prevent the nails from being fired when they are almost used up, thus avoiding problems caused by dry-firing.

[0003] In existing technology, the anti-dry-fire assembly of a single-firing nail gun (hereinafter referred to as nail gun) generally uses a limiting mechanism on the crankshaft component of the nail gun. Specifically, the crankshaft component acts as a safety mechanism for the nail gun. When the crankshaft component is not compressed, the trigger is not activated, thus achieving a safety effect that limits firing. To release the safety, one end of the crankshaft component needs to be pressed against the working surface, thereby pushing the crankshaft component to slide along the gun head and releasing the trigger safety. Correspondingly, a push block is provided on the nail pusher block of the magazine, and a limiting block is provided on the crankshaft component. When the number of nails in the magazine is small, the nail pusher block will drive the push block to move synchronously until the push block contacts the anti-dry-fire assembly, thereby pushing the anti-dry-fire pin in the anti-dry-fire assembly upward to between the limiting block and the gun body, thus preventing the crankshaft component from sliding and achieving the anti-dry-fire effect.

[0004] However, because nail guns may require replacement with different sizes of nails during use, and even nails of the same size may have significantly different spacing, the anti-dry-firing component may not activate in a timely manner. For details, please refer to [link / reference needed]. Figure 1 As shown, due to differences in nail size or spacing, the anti-aircraft firing mechanism (AAM) may fail to activate because the remaining nails in the magazine are insufficient to allow the pusher block to move the AAM to the position between the stop block and the receiver. During the disengagement process by pushing the crank mechanism, the pusher block should push the nail into the nail channel. However, because the AAM is blocked by the stop block and cannot move upwards, the pusher block's pushing portion is restricted by the AAM, preventing it from properly engaging the nail. When the pusher block fails to complete the engagement, the AAM malfunctions. Furthermore, if the pusher block only partially engages the nail, firing can cause the firing pin to strike part of the nail's cap, resulting in the nail striking the nail obliquely into the nail channel wall and damaging the receiver. Utility Model Content

[0005] In order to overcome at least one of the defects described in the prior art, the present invention provides an anti-dry-firing component, an anti-dry-firing device, and a nail gun, which can solve the problem of anti-dry-firing component failure caused by nail gun problems.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] An anti-air-firing assembly for a nail gun, characterized in that it comprises:

[0008] The mounting carrier has mounting holes;

[0009] An air defense pin is movably disposed in the mounting hole via a first elastic element. The air defense pin includes an abutment end and a transition end, and the transition end of the air defense pin is slidably connected to an abutment element.

[0010] The anti-aircraft pin is provided with a second elastic element between it and the abutment, and the second elastic element is used to push the abutment to reset.

[0011] Furthermore, the anti-aircraft pin has a limiting member in the middle, and the mounting hole has a first limiting part on the side near the abutting end. The first elastic member is located between the limiting member and the first limiting part.

[0012] Furthermore, the limiting member is a limiting sleeve, which is sleeved on the anti-aircraft pin, and a synchronous movement structure is provided between the limiting sleeve and the anti-aircraft pin. The outer surface of the limiting sleeve facing the adapter end is provided with a second limiting part. One side of the second limiting part is used to abut against the mounting carrier, and the other side abuts against the second elastic member. The tube body located between the second limiting part and the end face of the limiting sleeve facing the abutting end is slidably disposed in the mounting hole, and the end face of the limiting sleeve facing the abutting end abuts against the first elastic member.

[0013] Furthermore, the stiffness coefficient of the first elastic element is smaller than that of the second elastic element.

[0014] Furthermore, the anti-aircraft pin has a first stepped surface in the middle, and the inner wall of the limiting sleeve has a second stepped surface that abuts against the first stepped surface. The first stepped surface and the second stepped surface constitute the synchronous movement structure, so that when the limiting sleeve moves toward the sliding area of ​​the limiting block, the second stepped surface abuts against the first stepped surface and pushes the anti-aircraft pin toward the sliding area of ​​the limiting block.

[0015] Furthermore, the anti-aircraft pin protrudes to form a third stepped surface on the side near the adapter end, and the inner wall of the abutment is provided with a fourth stepped surface for abutting against the third stepped surface, so that when the abutment moves away from the abutment end, the third stepped surface and the fourth stepped surface abut against each other.

[0016] Furthermore, the outer wall of the abutting member is provided with a third limiting part, which abuts against the second elastic member.

[0017] Furthermore, the abutting end of the anti-aircraft pin is provided with a fourth limiting part, which is located outside the mounting hole and can abut against the plate surface of the mounting carrier in the circumferential direction of the mounting hole.

[0018] Furthermore, the mounting carrier is integrally formed with the gun head.

[0019] Furthermore, the end face of the push block facing the abutment is parallel to the end face of the abutment facing the push block.

[0020] This utility model also provides an anti-aircraft attack device, comprising:

[0021] Gun tip;

[0022] A magazine is located on one side of the gun head, and a pusher block is provided inside the magazine. The pusher block has a pusher portion extending to the outside of the magazine.

[0023] A crank component, slidably mounted on one side of the gun head and capable of reciprocating towards the gun body, includes a limiting block that slides synchronously with the crank component, and the sliding range of the limiting block is its sliding area; and

[0024] An anti-aircraft gun assembly is located on one side of the magazine and can restrict the sliding of the crank component under the push of the push block.

[0025] Wherein, the anti-aircraft attack component is the aforementioned anti-aircraft attack component.

[0026] When the limiting block slides to the direction of movement of the anti-aircraft pin, interfering with the movement of the anti-aircraft pin toward the sliding area of ​​the limiting block, the anti-aircraft pin assembly is shortened in the direction of movement of the anti-aircraft pin assembly by the action of the pushing block, so that the pushing pin block continues to move toward the direction of the limiting block, thus completing the pushing pin action.

[0027] This utility model also provides a nail gun, including the above-mentioned anti-dry-firing device.

[0028] In summary, the anti-dry-firing component, anti-dry-firing device, and nail gun provided by this utility model have the following technical effects:

[0029] When the pusher on the pusher block moves to contact the abutment, it pushes the abutment towards the sliding area of ​​the limit block. If the limit block does not block the path of the anti-dry-firing pin, the pin will move into the sliding area of ​​the limit block, restricting the movement of the crank assembly and thus completing normal anti-dry-firing restraint. If the limit block is in the path of the anti-dry-firing pin, it will prevent the pin from advancing further. In this case, the pusher pushes the abutment, allowing the pusher block to continue moving towards the limit block even when blocked. Therefore, even if the anti-dry-firing pin fails, the pusher block remains unrestricted by the anti-dry-firing assembly and completes the normal pusher action, preventing the inability to push the pin properly due to anti-dry-firing failure, which could lead to dry firing or even damage to the gun head. Furthermore, after the anti-aircraft pin fails to fire, the crank component resets. At this time, the push block synchronously pushes the abutment and the anti-aircraft pin toward the sliding area of ​​the limit block. When the anti-aircraft pin moves into the sliding area of ​​the limit block, the anti-aircraft pin is stopped.

[0030] In summary, the anti-aircraft gun assembly in this application can perform anti-aircraft gun limiting under normal conditions, and can also perform normal nailing and normal anti-aircraft gun limiting after nailing when the anti-aircraft gun assembly is restricted from operation.

They are only for the convenience of describing this utility model 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 this utility model.

[0043] 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.

[0044] See Figures 2-7This utility model discloses an anti-air-firing assembly for a nail gun. The nail gun has a gun head 1, a gun body 2, a magazine 3, and a crank rod component 4. The gun head 1 is located on one side of the gun body 2. The crank rod component 4 is slidably located on one side of the gun head 1 and can slide back and forth towards the gun body 2. The crank rod component 4 is provided with a limiting block 41, which slides synchronously with the crank rod component 4. The sliding range of the limiting block 41 is the limiting block sliding area 411. The magazine 3 is located on one side of the gun head 1 and has a nail pusher block 31 inside. The anti-air-firing assembly includes an anti-air-firing pin 51, a mounting carrier 53, a first elastic element 54, and a second elastic element 55. The anti-air-firing pin 51 includes an abutment end and a transition end. The transition end of the anti-air-firing pin 51 is slidably connected to an abutment 52 so that the abutment 52 can slide along the anti-air-firing pin 51. The anti-air-firing pin 51 is provided with a limiting element 511 in the middle. The mounting carrier 53 has a mounting hole 531, in which the anti-aircraft pin 51 slides. The mounting hole 531 has a first limiting portion 532 near the abutting end. A first elastic member 54 is located between the limiting member 511 and the first limiting portion 532. A second elastic member 55 is located between the limiting member 511 and the abutting member 52. The pusher block 31 has a pusher portion 311 extending outside the magazine 3. The abutting member 52 is located on the movement trajectory of the pusher portion 311, so that after the pusher portion 311 contacts the abutting member 52, it pushes the anti-aircraft pin 51 towards the sliding area 411 of the limiting block. When the limiting block 41 slides to the direction of movement of the anti-aircraft pin 51, interfering with the movement of the anti-aircraft pin 51 toward the sliding area 411 of the limiting block, the pushing block 311 pushes the abutment 52 toward the direction of the limiting block 41, so that the pusher block 31 continues to move toward the direction of the limiting block 41, thus completing the pusher action.

[0045] Specifically, refer to Figures 2-4 As shown, the nail gun includes a head 1, a body 2, a magazine 3, and a crank assembly 4. The head 1 is located on one side of the body 2 and has a nail-firing channel. The magazine 3 is located on one side of the head 1 for firing nails replenished from the magazine 3 into the nail-firing channel. The crank assembly 4 is slidably mounted on the head 1 and serves as the safety component of the nail gun. The safety of the nail gun is disengaged and activated by sliding the crank assembly 4. The crank assembly 4 has a limiting block 41, which slides synchronously with the crank assembly 4, and the sliding range of the limiting block 41 is the limiting block sliding area 411. The magazine 3 contains a nail-pushing block 31, which continuously and normally feeds nails into the nail-firing channel as they are consumed.

[0046] The anti-aircraft fire suppression assembly includes an anti-aircraft fire suppression pin 51, a mounting carrier 53, a first elastic element 54, and a second elastic element 55. The anti-aircraft fire suppression pin 51 includes an abutment end and a transition end. The transition end of the anti-aircraft fire suppression pin 51 is slidably connected to an abutment element 52, allowing the abutment element 52 to slide along the anti-aircraft fire suppression pin 51. A limiting element 511 is provided in the middle of the anti-aircraft fire suppression pin 51. The mounting carrier 53 has a mounting hole 531, in which the anti-aircraft fire suppression pin 51 slides. The mounting hole 531 has a first limiting portion 532 on the side near the abutment end. The first elastic element 54 is located between the limiting element 511 and the first limiting portion 532. The second elastic element 55 is located between the limiting element 511 and the abutment element 52. The pusher block 31 has a pusher portion 311 extending to the outside of the magazine 3. The abutment member 52 is located on the movement trajectory of the pusher portion 311, so that after the pusher portion 311 contacts the abutment member 52, it pushes the anti-aircraft pin 51 toward the sliding area 411 of the limiting block. When the limiting block 41 slides to the movement direction of the anti-aircraft pin 51 and interferes with the movement of the anti-aircraft pin 51 toward the sliding area 411 of the limiting block, the pusher portion 311 pushes the abutment member 52 toward the limiting block 41, so that the pusher block 31 continues to move toward the limiting block 41, completing the pusher action.

[0047] The working principle of the above structure:

[0048] When the anti-aircraft firing assembly is in normal use, as the nail in the magazine 3 is continuously consumed, the pusher block 31 continues to move upward. The pusher part 311, which moves synchronously with the pusher block 31, contacts the abutment 52. As the pusher part 311 moves, it synchronously pushes the abutment 52 and the anti-aircraft firing pin 51 connected to the abutment 52 toward the limiting block sliding area 411. While the anti-aircraft firing pin 51 moves toward the limiting block sliding area 411, the first elastic member 54 located between the limiting member 511 and the first limiting part 532 is compressed. When the pusher part 311 pushes the abutment end of the anti-aircraft firing pin 51 into the limiting block sliding area 411 through the abutment 52, the crank rod component 4 is interfered with by the limiting block 41 and the anti-aircraft firing pin 51, and can no longer slide toward the gun body 2, thus preventing the safety from being released and limiting firing, thereby achieving the anti-aircraft firing effect. When the push block 311 disengages from the contact member 52, the first elastic member 54 pushes the anti-aircraft pin 51 to reset the anti-aircraft pin 51.

[0049] When the anti-aircraft firing assembly is affected by the size of the nail or the gap between adjacent nails, as mentioned in the background art, i.e. when the crank assembly 4 is disengaged, the push block 311 is unable to push the anti-aircraft pin 51 towards the sliding area 411 of the limit block due to interference from the limit block 41. Furthermore, the push block 311, under the action of the push block 311, cannot fully push the nail into the nail channel. The push block 311 continues to move towards the sliding area 411 of the limit block, simultaneously pushing the abutment 52 to slide along the anti-aircraft pin 51. The second elastic element 55 is compressed, thus providing space for the push block 31 to complete the remaining nail-pushing action. The push block 31 continues to move upwards to complete the nail-pushing action. After this firing, the crank assembly 4 resets, and the push block 311 and / or the second elastic element 55 compress the first elastic element 54, simultaneously pushing the anti-aircraft pin 51 towards the sliding area 411 of the limit block, thereby completing the anti-aircraft firing limit.

[0050] It should be noted that, in order to ensure the orderly compression of the elastic elements, the first elastic element 54, and the second elastic element 55 that drive the pusher block 31 within the magazine 3, the tension generated by the elastic elements that drive the pusher block 31 within the magazine 3 is greater than the stress generated by the stiffness coefficients of the first elastic element 54 and the second elastic element 55. Optionally, the stiffness coefficient of the second elastic element 55 can be greater than that of the first elastic element 54, thereby ensuring that the first elastic element 54 is compressed preferentially, or that the compression ratio is much greater than that of the second elastic element 55, thus ensuring that the anti-aircraft pin 51 moves with the highest priority.

[0051] Alternatively, the first elastic element 54 and the second elastic element 55 can be springs, which facilitates the installation of the first elastic element 54 and the second elastic element 55.

[0052] In some embodiments, the limiting member 511 is a limiting sleeve, which is sleeved on the anti-aircraft pin 51, and a synchronous movement structure is provided between the limiting sleeve and the anti-aircraft pin 51. The outer surface of the limiting sleeve facing the adapter end is provided with a second limiting part 5111. One side of the second limiting part 5111 is used to abut against the mounting carrier 53, and the other side abuts against the second elastic member 55. The tube body located between the second limiting part 5111 and the end face of the limiting sleeve facing the abutting end is slidably disposed in the mounting hole 531, and the end face of the limiting sleeve facing the abutting end abuts against the first elastic member 54.

[0053] For details, please refer to Figure 5-7As shown, the limiting member 511 is a limiting sleeve, which is sleeved on the anti-aircraft pin 51. A synchronous movement structure is provided between the limiting sleeve and the anti-aircraft pin 51 to ensure that they can move synchronously. This ensures that under the indirect push of the push block 311, the limiting sleeve can effectively compress the first elastic member 54, and simultaneously push the anti-aircraft pin 51 towards the sliding area 411 of the limiting block. When the first elastic member 54 releases its elastic potential energy to reset, the limiting sleeve and the anti-aircraft pin 51 can reset synchronously. A second limiting part 5111 is provided on the outer surface of the limiting sleeve facing the adapter end. One side of the second limiting part 5111 is used to abut against the mounting carrier 53 to prevent the limiting sleeve from entering the mounting hole 531 too far, thereby preventing damage to the first elastic member 54. The tube body located between the second limiting part 5111 and the end face of the limiting sleeve facing the abutting end is slidably disposed in the mounting hole 531 to ensure that the limiting sleeve can slide in the mounting hole 531 according to the indirect action of the push block part 311 to push the first elastic member 54 to compress.

[0054] In some embodiments, the anti-aircraft pin 51 has a first stepped surface 512 in the middle, and the inner wall of the limiting sleeve has a second stepped surface 5112 that abuts against the first stepped surface 512. The first stepped surface 512 and the second stepped surface 5112 form a synchronous movement structure so that when the limiting sleeve moves toward the sliding area 411 of the limiting block, the second stepped surface 5112 abuts against the first stepped surface 512 and pushes the anti-aircraft pin 51 toward the sliding area 411 of the limiting block.

[0055] For details, please refer to Figure 5-7 As shown, the synchronous motion structure includes a first step surface 512 and a second step surface 5112. The anti-aircraft pin 51 has a first step surface 512 in the middle, and the inner wall of the limiting sleeve has a second step surface 5112 that abuts against the first step surface 512. When the limiting sleeve moves toward the sliding area 411 of the limiting block, the second step surface 5112 abuts against the first step surface 512 and pushes the anti-aircraft pin 51 toward the sliding area 411 of the limiting block, thereby realizing the synchronous motion of the limiting sleeve and the anti-aircraft pin 51 toward the sliding area 411 of the limiting block. When the push block 311 is separated from the contact with the abutment 52, under the action of gravity, the anti-aircraft pin 51 and the limiting sleeve move synchronously toward the direction away from the sliding area 411 of the limiting block.

[0056] In some embodiments, see Figure 5-7As shown, the anti-aircraft pin 51 has a protrusion on the side near the adapter end to form a third step surface 513. The inner wall of the abutment 52 is provided with a fourth step surface 521 for abutting against the third step surface 513. When the abutment 52 moves away from the abutment end, the third step surface 513 and the fourth step surface 521 abut against each other to prevent the abutment 52 from being dislodged from the anti-aircraft pin 51 by the action of the second elastic member 55.

[0057] In some embodiments, see Figure 5-7 As shown, the outer wall of the abutting member 52 is provided with a third limiting part 522, which abuts against the second elastic member 55. Through the abutment between the third limiting part 522 and the second elastic member 55, it can be ensured that the abutting member 52 and the limiting sleeve maintain a relatively stable state under the action of the second elastic member 55. This ensures that when the pushing block 311 pushes the abutting member 52, the force of the pushing block 311 on the abutting member 52 can be stably transmitted between the limiting sleeve and the first elastic member 54.

[0058] In some embodiments, see Figure 5-7 As shown, the abutting end of the anti-aircraft pin 51 is provided with a fourth limiting part 514. The fourth limiting part 514 is located outside the mounting hole 531 and can abut against the plate surface of the mounting carrier 53 around the mounting hole 531 to prevent the anti-aircraft pin 51 from entering the mounting hole 531.

[0059] In some embodiments, see Figure 2-3 As shown, the mounting carrier 53 is integrally formed with the gun head 1, thus facilitating the production of both the gun head 1 and the mounting carrier 53. Optionally, mounting holes 531 can be provided on the cover plate of the gun head 1 for the assembly of anti-aircraft components; in this case, the gun head 1 serves as the mounting carrier 53. Of course, the mounting carrier 53 can also be any other component of the nail gun.

[0060] In some embodiments, see Figure 5-7 As shown, the end face of the push block 311 facing the abutment 52 is parallel to the end face of the abutment 52 facing the push block 311. When the push block 311 pushes the abutment 52, the parallel end faces ensure that the force is evenly distributed on the contact surface. This avoids component displacement or damage caused by uneven force, and improves the stability and durability of the component.

[0061] This utility model also provides an anti-dry-firing device, including the above-mentioned anti-dry-firing component. The anti-dry-firing device can be mounted on a nail gun or other pneumatic or electric tools to complete the normal nail pushing action when the anti-dry-firing component fails due to the size of the nail and the gap between adjacent nails.

[0062] This utility model also provides a nail gun, including a gun body 2, a gun head 1, a magazine 3, and a crank rod component 4. The gun head 1 is located on one side of the gun body 2, and the magazine 3 is located on one side of the gun head 1. A nail pusher block 31 is provided inside the magazine 3, and the nail pusher block 31 has a pusher portion 311 extending to the outside of the magazine 3. The crank rod component 4 is slidably disposed on one side of the gun head 1 and can reciprocate towards the gun body 2. The crank rod component 4 is provided with a limiting block 41, which slides synchronously with the crank rod component 4, and the sliding range of the limiting block 41 is limited. The aforementioned anti-aircraft gun assembly is located on one side of the magazine 3 and is pushed by the push block 311, which can restrict the sliding of the crank rod component 4. When the limit block 41 slides to the direction of movement of the anti-aircraft gun pin 51 and interferes with the movement of the anti-aircraft gun pin 51 toward the limit block sliding area 411, the anti-aircraft gun assembly is shortened in the direction of movement of the anti-aircraft gun assembly by the push block 311, so that the push pin block 31 continues to move toward the limit block 41 and completes the push pin action.

[0063] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
