[0031] As can be seen from the background technology, there is an urgent need for an anti-dry firing device to prevent a nail gun from firing in vain.

[0032] The disclosed embodiments provide an anti-air-hit device and a nail gun. In the anti-air-hit device, when the number of nails in a magazine decreases to a threshold value, a lifting pin lifts up a limiting assembly, causing the limiting assembly to enter a moving path of a gun head, and the gun head cannot move relative to a nailing seat, thereby making it impossible for the nail gun including the anti-air-hit device to trigger a pre-nailing state, and the nail gun cannot shoot nails, thereby preventing the nail gun from firing in vain.

[0038] The following will describe the various embodiments of the present disclosure in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present disclosure, many technical details are provided in order to enable the reader to better understand the present disclosure. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present disclosure can be implemented.

[0039] Figure 1 An exploded view of the anti-air attack device provided in an embodiment of the present disclosure, Figure 2 A schematic diagram of the structure of the anti-air attack device provided in the embodiment of the present disclosure is shown in FIG. Figure 3 A schematic diagram of a structure of a lifting pin lifting limit assembly in an anti-runaway device provided in an embodiment of the present disclosure, Figure 4 Another structural schematic diagram of a lift pin lift limit assembly in the anti-runaway device provided in an embodiment of the present disclosure.

[0040] refer to Figures 1 to 4 The anti-air-driving device includes a nailing seat 10, a gun head 11, a magazine 12, a nail pushing assembly 13, a limit assembly 14 and a lifting pin 15. The nailing seat 10 has a through hole (not marked) penetrating the nailing seat 10 along a first direction X; the gun head 11 is movably connected to the nailing seat 10; the magazine 12 is connected to the nailing seat 10, and the magazine 12 is used to place nails along the first direction X; the nail pushing assembly 13 is movably arranged on the magazine 12 along the first direction X, and the nail pushing assembly 13 abuts on the nail in the magazine 12 that is farthest from the nailing seat 10; The limit assembly 14 is movably arranged in the through hole along the first direction X; the lifting pin 15 is arranged on the nail pushing assembly 13, and lifts the limit assembly 14 as the nail pushing assembly 13 moves, so that the limit assembly 14 enters the moving path of the gun head 11; wherein, as the nail enters the nail seat 10, the distance between the nail pushing assembly 13 and the nail seat 10 gradually decreases, and when the number of nails in the magazine 12 is reduced to a threshold value, the lifting pin 15 lifts the limit assembly 14, so that the limit assembly 14 enters the moving path of the gun head 11, and the threshold value is greater than or equal to 0.

[0041] It should be noted that the nailing action of the nail gun is completed in two steps. The first step is to press the gun head 11 toward the workpiece to be hit, so that the gun head 11 moves relative to the nailing seat 10, so that the nail gun is in a pre-nail state. The second step is that when the nail gun is in the pre-nail state, the switch of the nail gun is pressed, and the nail gun completes the nailing action through the striking mechanism. The two steps are sequential, that is, if the nail gun wants to complete the nailing action, it must first move the gun head 11 relative to the nailing seat 10 to put the nail gun in a pre-nail state.

[0042] The gun head 11 may include a gun mouth 111 and a bracket 112. The nailing seat 10 is also provided with a spring 101 and a fixing block 102. The end of the bracket 112 away from the gun mouth 111 is connected to the spring 101, and the spring 101 connects the fixing block 102 and the bracket 112. The spring 101 is used to allow the gun head 11 to have a moving space. The gun mouth 111 of the gun head 11 is pressed to drive the nailing seat 10 to move. The spring 101 is compressed to a predetermined position, so that the nail gun is in a pre-nailing state, and the nail gun can complete the nailing action. After the nailing is completed, under the elastic force of the spring 101, the gun mouth 111 moves to the initial position. At this time, the nail gun is not in the pre-nailing state, and the nail gun cannot normally nail.

[0043] The movement path of the limiting component 14 entering the gun head 11 is actually the end of the limiting component 14 abutting against the bracket 112 away from the gun nozzle 111 .

[0044] Figure 5 A partial cross-sectional view of a lifting pin lifting limit assembly in an anti-runaway device provided in an embodiment of the present disclosure, Figure 6 A partial cross-sectional view of the anti-dry attack device provided in an embodiment of the present disclosure.

[0045] Combined with reference Figure 1 , Figure 5 and Figure 6 In some embodiments, the limit assembly 14 includes a limit block 141 and a limit rod 142, a sleeve 143 and a first elastic member 144 connected to each other. The limit block 141 is located at the end of the limit rod 142 away from the lift pin 15, and the limit block 141 can enter and exit the moving path of the gun head 11; the sleeve 143 is sleeved on the outer periphery of the limit rod 142; the first elastic member 144 is sleeved on the outer periphery of the limit rod 142 and is located between the sleeve 143 and the limit block 141.

[0046] The limiting block 141 is used to directly contact the end of the bracket 112 away from the gun nozzle 111 .

[0047] The limiting rod 142 is used for directly contacting the lifting pin 15 .

[0048] The sliding sleeve 143 is sleeved on the outer circumference of the limiting rod 142 , and the sliding sleeve 143 has a guiding function to enable the limiting rod 142 to move along the first direction X.

[0049] The first elastic member 144 is located between the sliding sleeve 143 and the limiting block 141. When the lifting pin 15 lifts the limiting rod 142, the first elastic member 144 is in a compressed state. After that, when the lifting pin 15 is away from the limiting rod 142, the limiting block 141 can be away from the moving path of the gun head 11 and return to the initial position under the elastic force of the first elastic member 144. In other words, the first elastic member 144 is used to reset the limiting block 141 and the limiting rod 142.

[0050] In some embodiments, the nailing seat 10 further includes a boss 103 , which is located in the through hole and between the limiting block 141 and the first elastic member 144 . The boss 103 also abuts against the limiting rod 142 .

[0051] When the lifting pin 15 does not lift the limiting rod 142, the boss 103 is used to provide a supporting force for the limiting block 141. When the lifting pin 15 lifts the limiting rod 142, the boss 103 is used to provide a contact surface when the first elastic member 144 is compressed, thereby preventing the limiting rod 142 and the limiting rod 142 from being pushed out of the through hole under the action of the lifting pin 15.

[0052] In some embodiments, the slide 143 includes a sleeve 1431 and a blocking portion 1432, the blocking portion 1432 is located at one end of the sleeve 1431 close to the lifting pin 15, and at least part of the sleeve 1431 is located in the through hole. When the number of nails in the magazine 12 is reduced to a threshold, the lifting pin 15 lifts the limiting assembly 14, and the abutting portion 152 abuts against the nailing seat 10; the limiting assembly 14 also includes a nut 145, which is fixedly connected to the limiting rod 142 and abuts against the blocking portion 1432.

[0053] When the lifting pin 15 does not lift the limiting rod 142, part of the sleeve 1431 is located in the through hole, and the blocking part 1432 does not abut against the nail seat 10. When the lifting pin 15 lifts the limiting rod 142, the sleeve 1431 is completely located in the through hole, and the blocking part 1432 abuts against the nail seat 10, thereby preventing the limiting rod 142 and the limiting rod 142 from being pushed out of the through hole under the action of the lifting pin 15.

[0054] In some embodiments, the push pin assembly 13 has a blind hole (not marked), the lifting pin 15 is arranged in the blind hole, and the anti-air strike device also includes a second elastic member 16, one end of the second elastic member 16 abuts against the bottom of the blind hole, and the other end abuts against the lifting pin 15.

[0055] The blind hole is used to accommodate the lift pin 15 .

[0056] When the number of nails decreases to the threshold value and the lifting pin 15 lifts the limiting component 14, the second elastic member 16 can provide a buffering force for the lifting pin 15 to lift the limiting component 14, thereby preventing the lifting pin 15 and the limiting component 14 from being damaged due to excessive impact force generated by rigid collision, thereby improving the reliability of the anti-air strike device.

[0057] In some embodiments, the lifting pin 15 includes a rod body 151 and an abutment portion 152, and a portion of the second elastic member 16 is sleeved on the outer periphery of the rod body 151. The anti-air strike device also includes a limit pin 136, and the limit pin 136 abuts against the end face of the abutment portion 152 near the limit assembly 14.

[0058] A portion of the second elastic member 16 is sleeved on the outer circumference of the rod body 151 , and one end of the second elastic member 16 away from the pin pushing assembly 13 abuts against the abutting portion 152 .

[0059] The limiting pin 136 can prevent the lifting pin 15 from being separated from the blind hole due to the elastic force of the second elastic member 16 .

[0060] In addition, the limit pin 136 abuts against the end surface of the abutment portion 152 close to the limit assembly 14. The limit pin 136 can also allow the second elastic member 16 to be in a slightly contracted state when the lifting pin 15 does not lift the limit assembly 14, so that when the number of nails reaches a threshold, the lifting pin 15 can directly lift the limit rod 142 of the limit assembly 14 when it contacts the limit rod 142, and the second elastic member 16 will not shrink first and the limit rod 142 will not be lifted.

[0061] It is understandable that when the number of nails reaches a threshold and the lifting pin 15 contacts the limiting rod 142 , the elastic force of the second elastic member 16 can be greater than the elastic force of the first elastic member 144 , thereby ensuring that the lifting pin 15 can directly lift the limiting rod 142 after contacting the limiting rod 142 .

[0062] Figure 7 A partial structural diagram of a magazine in an anti-dry-fire device provided in an embodiment of the present disclosure, Figure 8 A schematic diagram of a structure of a lifting pin non-lifting limit assembly in an anti-runaway device provided in an embodiment of the present disclosure, Fig. 9 Another structural schematic diagram of the lifting pin lifting limit assembly in the anti-air striking device provided for the implementation of the present disclosure. In order to illustrate the nail and the cavity for placing the nail, Figure 8 and Fig. 9 The figure shows the shell of the magazine without showing part of it; in order to better illustrate the magnetic components on the limit assembly, the Hall sensor is separated from the nailing seat. In actual use, the Hall sensor should be connected to the nailing seat.

[0063] Combined with reference Figures 7 to 9In some embodiments, the magazine 12 includes a cavity 121 for placing the nail 20 and an opening 122 connected to the cavity 121, the opening 122 extends along the first direction X, and a portion of the nail pushing assembly 13 passes through the opening 122 and is arranged in the cavity 121; the anti-air strike device also includes a third elastic member 17, the third elastic member 17 is shielded on the side of the opening 122 away from the cavity 121, one end of the third elastic member 17 is connected to the magazine 12, and the other end is connected to the nail pushing assembly 13, the third elastic member 17 is used to push the nail pushing assembly 13 to move in the opening 122 along the first direction X to push the nail 20.

[0064] One end of the third elastic member 17 is connected to the magazine 12, and the other end is connected to the nail pushing assembly 13, and the third elastic member 17 is shielded on the side of the opening 122 away from the cavity 121, so that the nail 20 is surrounded by the magazine 12 and the third elastic member 17. In this way, dust, mud and other hard impurities cannot contact the nail 20 through the opening 122 during the nail shooting process, so that the nail 20 will not be skewed due to impurities entering the interior of the magazine 12, thereby improving the reliability of the magazine 12.

[0065] Fig.10 Another structural schematic diagram of the lifting pin not lifting the limit assembly in the anti-runaway device provided by the embodiment of the present disclosure, Fig.11 It is another structural schematic diagram of a non-lifting limit assembly of a lifting pin in an anti-runaway device provided by an embodiment of the present disclosure, Fig.12 This is another structural schematic diagram of a non-lifting limit assembly of a lifting pin in an anti-air strike device provided in an embodiment of the present disclosure. Fig.10 and Fig.11 Schematic diagrams of two structures in the same state (the distance between the lifting pin and the limiting component is the same) at different viewing angles.

[0066] refer to Figure 8 , Fig.10 and Fig.11 , the nail pushing assembly 13 abuts against the nail 20 of the magazine 12 which is farthest from the nail driving seat 10. At this time, there are a large number of nails 20, and the distance between the lifting pin 15 on the nail pushing assembly 13 and the limiting assembly 14 is relatively far. Fig.12 As the number of nails 20 decreases, under the elastic force of the third elastic member 17, the distance between the lifting pin 15 on the nail pushing assembly 13 and the limiting assembly 14 is closer. Fig. 9 When the number of nails 20 is reduced to a threshold value, the lifting pin 15 contacts the limiting assembly 14 and lifts the limiting assembly 14 to the moving path of the gun head 11, preventing the gun head 11 from moving relative to the nailing seat 10, thereby avoiding empty firing of the nail gun.

[0067] Understandably, Fig. 9FIG. 4 illustrates a case where the threshold value of the number of nails 20 is greater than 0. In fact, the threshold value of the number of nails 20 may also be 0 or other values.

[0068] The third elastic member 17 may be a coil spring.

[0069] It is understandable that during the nail pushing process, the elastic force of the third elastic member 17 is greater than the elastic force of the second elastic member 16 . This arrangement can ensure that the third elastic member 17 can drive the nail pushing assembly 13 to push the nail 20 to move.

[0070] Combined with reference Figure 1 and Figure 7 In some embodiments, the pin pushing assembly 13 includes a pin pushing block 131, a main body 132 and a connecting portion 133, the pin pushing block 131 is located in the cavity 121; the main body 132 is located on the side of the opening 122 away from the cavity 121, and the main body 132 is connected to the third elastic member 17; the connecting portion 133 connects the pushing block and the main body 132, and part of the connecting portion 133 is arranged in the opening 122.

[0071] The nail pushing block 131 is placed in the cavity 121 for direct contact with the nail 20 .

[0072] The main body 132 is located outside the magazine 12 and is used to be connected to the third elastic member 17 .

[0073] The connecting portion 133 is used to connect the nail pushing block 131 in the magazine 12 with the main body 132. The connecting portion 133 is clamped in the opening 122, so that the nail pushing assembly 13 can move along the extension direction of the opening 122 (i.e., the first direction X), that is, the opening 122 provides a moving path for the nail pushing assembly 13.

[0074] In some embodiments, the pin pushing block 131 and the connecting portion 133 may be an integrally formed structure.

[0075] In some embodiments, the magazine 12 includes a first side wall 123 and a second side wall 124 that are arranged opposite to each other, and the edge of the first side wall 123 and the edge of the second side wall 124 are spaced apart to form an opening 122. That is, the opening 122 of the embodiment of the present disclosure is arranged at the edge of the first side wall 123 and the second side wall 124, rather than being arranged on the first side wall 123.

[0076] In some embodiments, the magazine 12 includes a transparent area 1231, which is used to observe the number of nails 20 in the magazine 12. This arrangement facilitates the user to observe the number of nails 20 in the magazine 12 during the nail shooting process using a nail gun containing the magazine 12, so that the user can replenish the nails 20 in time.

[0077] In a specific example, the first side wall 123 of the magazine 12 is partially a transparent area 1231 , that is, the first side wall 123 includes a transparent area 1231 and an opaque area 1232 .

[0078] In other examples, the first side wall may also be entirely configured as a transparent area.

[0079] The transparent area 1231 of the first side wall 123 may be an acrylic plate.

[0080] In some embodiments, the magazine 12 further includes a side plate 125, which is connected to the first side wall 123 and abuts against the nail pushing assembly 13. The side plate 125 can provide a certain guiding and supporting effect during the nail pushing process of the nail pushing assembly 13, so that the nail pushing movement of the nail pushing assembly 13 can be more stable and reliable.

[0081] In some embodiments, the nail pushing block 131 has a protrusion 134 protruding from the surface on the surface facing the first side wall 123, and the first side wall 123 has a clamping hole 126 penetrating the first side wall 123, and the protrusion 134 can be clamped in the clamping hole 126. When the magazine 12 is stapled, the protrusion 134 can be clamped in the clamping hole 126, so that the nail pushing assembly 13 will not move under the action of the third elastic member 17, which is convenient for the user to staple. After the staple is completed, the user can make the protrusion 134 not clamped in the clamping hole 126, and the nail pushing assembly 13 can abut against the nail 20 under the action of the third elastic member 17 and push the nail 20 to move.

[0082] In some embodiments, the nail pushing assembly 13 further includes an elastic part (not shown) and a button 135. The elastic part is disposed in the main body 132, connected to the connecting part 133, and the elastic part is retracted in the second direction Y to drive the protrusion of the nail pushing block 131 connected to the connecting part 133 to move in the second direction Y, so that the protrusion can be clamped in the clamping hole 126; part of the button 135 is located in the main body 132 and abuts against the elastic part. When the magazine 12 is bound, the protrusion 134 is clamped in the clamping hole 126 under the elastic force of the elastic part, so that the nail pushing assembly 13 will not move under the action of the third elastic member 17, which is convenient for the user to bind. After the binding is completed, the user can press the button 135 to compress the elastic part, and the protrusion 134 is away from the clamping hole 126. The nail pushing assembly 13 can abut against the nail 20 under the action of the third elastic member 17 and push the nail 20 to move.

[0083] In some embodiments, the anti-air-strike device further includes a magnetic element 18, a Hall sensor 19, and a prompt unit (not shown), wherein the magnetic element 18 is disposed on the limit assembly 14; the Hall sensor 19 is disposed on the nailing seat 10, and the Hall sensor 19 is used to detect the position of the magnetic element 18; the prompt unit is connected to the Hall sensor 19, and when the number of nails 20 in the magazine 12 is reduced to a threshold value, the lifting pin 15 lifts the limit assembly 14, the Hall sensor 19 detects the position change of the magnetic element 18 and sends a signal to the prompt unit, and the prompt unit sends a prompt message in response to the signal. With such a configuration, when the number of nails 20 in the magazine 12 is less than the threshold value, the user can be promptly prompted by the prompt unit, and the user can replenish the nails 20 in the magazine 12 in time according to the prompt information, which can enhance the user's experience of using the anti-air-strike device.

[0084] Specifically, combined with reference Figure 1 and Fig. 9 When the lifting pin 15 lifts the limit assembly 14, the magnetic element 18 on the limit assembly 14 can be opposite to the Hall sensor 19 and are located on the same horizontal plane. At this time, the distance between the Hall sensor 19 and the magnetic element 18 is relatively close, and the Hall sensor 19 can detect the position change of the magnetic element 18. This means that the lifting pin 15 does not lift the limit assembly 14, and the distance between the magnetic element 18 on the limit assembly 14 and the Hall sensor 19 is relatively large. When the lifting pin 15 lifts the limit assembly 14, the distance between the magnetic element 18 on the limit assembly 14 and the Hall sensor 19 is relatively small. The Hall sensor 19 can detect the position distance change of the magnetic element 18 and send a signal to the prompt unit. The prompt unit responds to the signal to prompt the user that the magazine 12 is missing a nail.

[0085] The prompting unit may be a device that uses light to prompt the user, such as an LED lamp, or a device that uses sound to prompt the user, such as a speaker or a horn, or the prompting unit may be a device that provides both light and sound prompts.

[0086] In the above-mentioned anti-air-driving device, when the number of nails 20 in the magazine 12 is greater than a threshold value, the lifting pin 15 will not lift the limiting assembly 14, and the limiting assembly 14 will not enter the moving path of the gun head 11 to limit the gun head 11, and the gun head 11 can move relative to the nailing seat 10, so that the nail gun containing the anti-air-driving device can trigger the pre-nailing state, and the nail gun can normally shoot nails. When the number of nails 20 in the magazine 12 is reduced to a threshold value, the lifting pin 15 lifts the limiting assembly 14, so that the limiting assembly 14 enters the moving path of the gun head 11, and the gun head 11 cannot move relative to the nailing seat 10, so that the nail gun containing the anti-air-driving device cannot trigger the pre-nailing state, and the nail gun cannot shoot nails, thereby avoiding the nail gun from firing.

[0087] Other embodiments of the present disclosure also provide a nail gun including the above-mentioned anti-airstrike device. The nail guns provided by other embodiments of the present disclosure are described below. It should be noted that the parts that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0088] A nail gun is used to drive nails.
