[0034] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0035] Example 1

[0036] like Figures 2 to 6 As shown, the present embodiment 1 provides an electric-fired nail shooter, comprising a firing pin seat cover 1 , in which a firing pin 2 and a push-type electromagnet 3 for pushing the firing pin 2 are installed.

[0037] The firing pin 2 is located at the front end of the firing pin seat 1, and the push electromagnet 3 is installed at the rear end of the firing pin seat 1. The iron core in the push electromagnet 3 is on the same axis as the firing pin 2. When the push electromagnet 3 is energized, the iron core in the push electromagnet 3 moves forward, and the iron core in the push electromagnet 3 pushes the firing pin 2 forward quickly, thereby enabling the firing pin 2 to fire the integrated nail bullet in the launch tube 18.

[0038] The push-type electromagnet 3 is a direct use of the electromagnet in the prior art. When the present invention is in use, the push-type electromagnet 3 is connected to an external power supply, and the external power supply itself carries a switch, that is, by starting the switch on the external power supply to power on or off the push-type electromagnet 3, the push-type electromagnet 3 is controlled, thereby achieving the firing of the firing pin 2.

[0039] The firing end of the firing pin 2 is provided with a firing pin seat 4, and the iron core of the push-type electromagnet 3 is fixedly connected to the firing pin seat 4. The firing pin seat 4 is slidably matched with the firing pin sleeve seat 1, and the end surface of the firing pin seat 4 close to the push-type electromagnet 3 is provided with a threaded hole, and the iron core of the push-type electromagnet 3 is provided with an external thread matched with the threaded hole, so that the iron core of the push-type electromagnet 3 is threadedly fixed with the firing pin seat 4, making the assembly between the push-type electromagnet 3 and the firing pin seat 4 more convenient; in order to make it more convenient to control the depth of the iron core of the push-type electromagnet 3 inserted into the firing pin seat 4 when assembling the push-type electromagnet 3 and the firing pin seat 4, a limit plate can be provided on the iron core of the push-type electromagnet 3, so that when the push-type electromagnet 3 and the firing pin seat 4 are assembled, when the limit plate and the firing pin seat 4 are pressed tightly, the iron core of the push-type electromagnet 3 and the firing pin seat 4 are installed to a fixed position, thereby effectively ensuring that the iron core of the push-type electromagnet 3 and the firing pin seat 4 can be accurately installed.

[0040] The firing pin seat 4 includes a base 41 and a nail cap groove 42 provided on the base 41; the firing pin 2 is installed in the nail cap groove 42. The base 41 is slidably matched with the firing pin seat sleeve 1, the nail cap groove 42 is located on the end surface of the base 41 away from the push-type electromagnet 3, and the nail cap groove 42 is matched with the needle cap of the firing pin 2. The center of the nail cap groove 42 is coaxially arranged with the firing pin 2, which not only ensures the coaxiality of the firing pin 2 and the firing pin seat 4, but also makes the installation of the firing pin 2 more stable.

[0041] The base 41 is also covered with a cap 43 for pressing the firing pin 2, and the cap 43 is threadedly connected to the base 41. The base 41 is in the shape of a stepped shaft, and the large diameter end of the base 41 is connected to the push electromagnet 3, and the large diameter end of the base 41 is slidably matched with the firing pin seat sleeve 1; the nail cap groove 42 is located on the end surface of the small diameter end of the firing pin seat 4, and the small diameter end of the base 41 is provided with an external thread, and the inner wall of the cap 43 is provided with an internal thread that matches the external thread, so that the cap 43 can be directly installed on the base 41 through threaded matching during installation, which can not only achieve the compression of the firing pin 2 needle cap, but also make the firing pin 2 The installation is realized, and the installation and removal of the firing pin 2 are more convenient; the cap 43 has a through hole that matches the firing pin 41, and the outer surface of the cap 43 is flush with the large diameter end surface of the base 41, so that the cap 43 and the firing pin seat 4 sleeve can achieve sliding cooperation, ensuring the cooperation length of the firing pin seat 4 and the firing pin seat sleeve 1, reducing the shaking of the firing pin 2, and making the firing pin 2 coaxial with the firing pin sleeve 1 during the forward movement, so that the firing pin 2 can accurately fire the integrated nail bullet in the launch tube 18. When it is necessary to assemble the firing pin 2 and the firing pin seat 4, first install the needle cap of the firing pin 2 in the nail cap groove 42, pass the through hole on the cap 43 through the firing pin 2, and finally tighten the cap 43 to fix it on the base 41, so that the assembly between the firing pin 2 and the firing pin seat 4 is faster and more convenient.

[0042] The firing base 5 is also installed at the rear end of the firing pin seat 1, and a clamping structure for clamping the push electromagnet 3 is installed in both the firing base 5 and the firing pin seat 1. The firing base 5 is in the shape of a sleeve, and the front end of the firing base 5 is fixedly sleeved on the firing pin seat 1 through a threaded connection, and the two ends of the push electromagnet 3 are clamped and fixed together through the clamping structure, so that the two ends of the push electromagnet 3 are simultaneously limited, thereby effectively preventing the push electromagnet 3 from moving in the firing pin seat 1, realizing the installation of the push electromagnet 3, and making the installation of the push electromagnet 3 faster and more convenient.

[0043] The firing base 5 has a limit stop 6, and a buffer spring 7 is arranged between the rear end of the push electromagnet 3 and the limit stop 6; the firing pin seat 1 has a limit stop Ⅰ8, and the front end of the push electromagnet 3 is pressed against the limit stop Ⅰ8. The limit stop Ⅰ8 in the firing pin seat 1 is located at the rear end of the firing pin seat 1, so that the opening diameter of the rear end of the firing pin seat 1 is larger than the opening diameter of the front end of the firing pin seat 1, so that the inner wall of the firing pin seat 1 is in the shape of a stepped hole. When the push electromagnet 3 needs to be installed, the limit stop Ⅰ8 in the firing pin seat 1 can limit the front end of the push electromagnet 3; the limit stop 6 is integrally arranged with the firing base 5, and the limit stop 6 is annular, one end of the buffer spring 7 is pressed against the limit stop 6, and the other end of the buffer spring 7 is pressed against the push electromagnet 3, so that the front end of the push electromagnet 3 is pressed against the limit stop Ⅰ8, thereby realizing the installation of the push electromagnet 3. When the push electromagnet 3 needs to be installed, the push electromagnet 3 is first placed into the firing pin seat 1, and the buffer spring 7 is placed into the firing base 5. As the firing base 5 and the firing pin seat 1 are tightened and fixed, the buffer spring 7 is gradually compressed. As the buffer spring 7 is compressed, the thrust of the buffer spring 7 on the push electromagnet 3 becomes greater. When the firing base 5 and the firing pin seat 1 are completely tightened, the buffer spring 7 is completely pressed against the push electromagnet 3, so that the front end of the push electromagnet 3 is pressed against the limit stop Ⅰ8, and the rear end of the push electromagnet 3 is pressed against the buffer spring 7, thereby realizing the installation of the push electromagnet 3. At this time, the installation method can not only enable the push electromagnet 3 to be quickly installed, but also make the disassembly of the push electromagnet 3 more convenient.

[0044] The front end of the firing pin seat sleeve 1 is also sleeved with a slidable return spring seat 13, and a return spring 14 is pressed tightly between the return spring seat 13 and the firing base 5; the front end of the firing base 5 is also installed with a jacket 15, and the rear end of the return spring seat 13 is slidably matched with the jacket 15. The return spring seat 13 is coaxially arranged with the firing pin seat sleeve 1, and the return spring seat 13 can slide forward and backward on the firing pin seat sleeve 1; the jacket 15 is installed on the firing base 5 through a threaded connection, and the firing base 5 is also provided with a limit stopper, which can not only prevent the jacket 15 from being displaced after being fixed on the firing base 5, but also effectively limit the position of the jacket 15 when it is assembled. The return spring 14 is sleeved on the firing pin sleeve 1, one end of the return spring 14 is against the end surface of the return spring seat 13, and the other end of the return spring 14 is against the end surface of the firing base 5. In order to prevent the return spring seat 13 from directly sliding off the firing pin sleeve 1, a limiting mechanism for limiting the return spring seat 13 can also be installed on the firing pin sleeve 1 or the outer sleeve 15.

[0045] The outer wall of the firing pin sleeve 1 also has a limit ring 16, which is located at the front end of the firing pin sleeve 1, and the inner wall of the return spring seat 13 has a stopper structure 17 that cooperates with the limit ring 16. The limit ring 16 is integrally formed with the firing pin sleeve 1, and the limit ring 16 and the inner wall of the return spring seat 13 are slidably matched; the stopper structure 17 is located on the inner wall of the return spring seat 13, so that the opening diameter of the rear end of the return spring seat 13 is smaller than the opening diameter of the front end of the return spring seat 13; through the cooperation of the limit ring 16 and the stopper structure 17, not only can the return spring seat 13 slide smoothly along the firing pin sleeve 1, but the return spring seat 13 can also be limited when moving, effectively preventing the return spring seat 13 from falling off directly from the firing pin sleeve 1. The limiting structure can also be a limiting pin installed on the firing pin sleeve 1 and a guide groove opened on the return spring seat 13. The limiting pin is inserted into the guide groove. This method can also achieve the limitation of the return spring seat 13, but this structure is more complicated to assemble.

[0046] A launch tube 18 is also installed at the front end of the return spring seat 13, and a silencer cover 19 is fixedly provided on the launch tube 18. The launch tube 18 is threadedly connected and fixed to the return spring seat 13, and the rear end of the launch tube 18 is inserted in the return spring seat 13; the silencer cover 19 is threadedly fixedly sleeved on the outer wall of the launch tube 18, and a heat dissipation hole 27 connected to the inside of the silencer cover 19 is provided on the launch tube 18, so as to facilitate the diffusion of the heat and sound generated after the explosion of the integrated nail bullet, thereby achieving the effect of heat dissipation and silencer.

[0047] The firing end of the firing pin seat cover 1 is also installed with a firing pin sleeve 20, the firing end of the firing pin 2 is inserted in the firing pin sleeve 20, and the front end of the firing pin sleeve 20 is inserted in the launching tube 18; the firing end of the firing pin seat cover 1 and the firing end of the firing pin sleeve 20 are also provided with a pressure relief hole 21. The rear end of the firing pin sleeve 20 is inserted into the firing pin seat sleeve 1, and in order to facilitate the installation of the firing pin sleeve 20, the rear end of the firing pin sleeve 20 can be set to a step shape, and a step hole is opened at the front end of the firing pin seat sleeve 1. After the rear end of the firing pin sleeve 20 is installed in the step hole on the firing pin seat sleeve 1, the firing pin sleeve 20 and the firing pin seat sleeve 1 are welded and fixed, so that the firing pin sleeve 20 is installed; the firing pin 2 is coaxially arranged with the firing pin sleeve 20, and the firing pin sleeve 20 is coaxially arranged with the launch tube 18. When the firing pin 2 is pushed forward by the push electromagnet 3, the firing pin 2 can be guided forward by the firing pin sleeve 20, so that the needle tip of the firing pin 2 can smoothly enter the launch tube 18 and accurately fire the integrated nail bullet in the launch tube 18.

[0048] There is at least one pressure relief hole 21 on the firing pin seat cover 1 and one pressure relief hole 21 on the firing pin sleeve 20, and the plurality of pressure relief holes 21 are evenly spaced along the circumference of the central axis of the firing pin sleeve 20. By providing the pressure relief holes 21 on the firing pin sleeve 20 and the firing pin seat cover 1, after the integrated nail bullet is fired, the heat or air pressure diffused into the gap between the firing pin sleeve 20 and the firing pin 2 can be directly diffused through the pressure relief hole 21 on the firing pin sleeve 20, or the heat or air pressure diffused into the gap between the firing pin sleeve 20 and the firing pin 2 can be directly diffused through the pressure relief hole 21 on the firing pin seat cover 1 after the firing pin 2 retreats. This can not only ensure the pressure balance between the firing pin sleeve 20 and the firing pin 2, but also effectively diffuse the heat in the firing pin sleeve 20.

[0049] In this embodiment, the front end of all components and the firing end of the components are both ends of the components close to the launching tube 18 , and the rear end of the components and the fired end of the components are both ends of the components away from the launching tube 18 .

[0050] When the nail shooter needs to work, the integrated nail bullet is first loaded into the launch tube 18, and the front end face of the launch tube 18 is close to the fastened surface of the building. At this time, the launch tube 18 is manually pushed, so that the launch tube 18 moves backward synchronously with the return spring seat 13, so that the return spring 14 is gradually compressed. When the return spring 14 is completely compressed, the firing end of the firing pin sleeve 20 contacts the integrated nail bullet, and the switch on the external power supply of the push electromagnet 3 is turned on, so that the external power supply supplies power to the push electromagnet 3. The push electromagnet 3 is energized, and the iron core of the push electromagnet 3 is pushed out, so that the push electromagnet 3 pushes the firing pin seat 4 forward. When the firing pin seat 4 moves forward, the firing pin 2 fixed to the firing pin seat 4 moves forward rapidly along the firing pin sleeve 20, so that the firing pin 2 fires the integrated nail bullet, thereby detonating the integrated nail bullet, and finally the nails on the integrated nail bullet are shot into the building body, completing the fastening of the nails. The recoil force generated when the integrated nail bullet explodes directly acts on the push electromagnet 3 through the firing pin 2 and the firing pin seat 4, and the rearward force received by the push electromagnet 3 is directly buffered by the buffer spring 7.

[0051] When the nails on the integrated nail bullet are shot into the building matrix, the switch on the external power supply is turned off to stop the external power supply to the push electromagnet 3, the push electromagnet 3 is powered off, and the iron core of the push electromagnet 3 is reset. When the iron core of the push electromagnet 3 is reset, the push electromagnet 3 drives the firing pin seat 4 and the firing pin 2 to reset; at the same time, the manual force applied to the launching tube 18 is released, the reset spring 14 loses the thrust of the reset spring seat 13, and the reset spring 14 pushes the reset spring seat 13 to reset through its own elastic force, thus completing the preparation for the next construction.

[0052] Example 2

[0053] The difference between this embodiment 2 and embodiment 1 is that:

[0054] like Figures 7 to 10 As shown, this embodiment 2 provides an electric-fired nail shooter, wherein the firing pin seat 1 has a firing seat 9 in the middle, and the firing pin 2 is slidably installed in the firing pin seat 1; the firing seat 9 is provided with a guide hole 10 passing through both ends of the firing pin seat; and the iron core of the push-type electromagnet 3 is inserted in the guide hole 10. The firing seat 9 and the firing pin seat cover 1 are an integral structure, and by installing the firing seat 9, the two ends of the firing pin seat cover 1 are separated; the guide hole 10 passes through the firing seat 9, and the central axis of the guide hole 10 is in the same straight line with the central axis of the firing pin 2; the firing pin 2 is installed in the front end of the firing pin seat cover 1, and the firing pin 2 can move forward or backward at the front end of the firing pin seat cover 1; the push electromagnet 3 is close to and slidably cooperates with the guide hole 10, so that the iron core of the push electromagnet 3 can be guided by the guide hole 10 during the forward or backward process. When the push electromagnet 3 is energized, the iron core of the push electromagnet 3 can move forward rapidly along the guide hole 10, so that the iron core of the push electromagnet 3 can accurately hit the firing pin 2 and move forward rapidly.

[0055] The firing end of the firing pin 2 has a fixed shaft 11, and the fixed shaft 11 is inserted into the guide hole 10. The fixed shaft 11 is integrally arranged with the firing pin 2, and the fixed shaft 11 and the guide hole 10 are clearance-matched. When the firing pin 2 is not fired and moves forward, the fixed shaft 11 contacts the iron core of the push electromagnet 3. When the push electromagnet 3 is energized, the iron core of the push electromagnet 3 quickly hits the fixed shaft 11 and moves forward, thereby making the firing pin 2 move forward quickly as a whole.

[0056] The firing end of the firing pin seat 1 is also equipped with a firing pin sleeve 20, the front end of the firing pin sleeve 20 is inserted into the launch tube 18, and the rear end of the firing pin sleeve 20 has a clamping platform 22 that slides with the inner wall of the firing pin seat 1, and a support spring 23 is installed between the clamping platform 22 and the launch tube 18. The firing pin sleeve 20 is movably installed in the front end of the firing pin seat sleeve 1, that is, the firing pin sleeve 20 can move in the firing pin seat sleeve 1; the clamping platform 22 is integrally arranged with the firing pin sleeve 20, and the diameter of the clamping platform 22 is clearance matched with the inner diameter of the front end of the firing pin seat sleeve 1, thereby ensuring that the firing pin sleeve 20 can smoothly move forward and backward along the front end of the firing pin seat sleeve 1; the front end of the firing pin sleeve 20 is slidingly matched with the launch tube 18, that is, the firing pin sleeve 20 is clearance matched with the launch tube 18, and the central axis of the firing pin sleeve 20 is in the same straight line with the central axis of the launch tube 18; the support spring 23 is sleeved on the firing pin sleeve 20, and by installing the support spring 23, the support spring 23 can press the firing pin sleeve 20 in the firing pin seat sleeve 1. By movably installing the firing pin sleeve 20 in the firing pin seat sleeve 1, not only the assembly between the firing pin sleeve 20 and the firing pin seat sleeve 1 is made more convenient, but also the firing pin sleeve 20 can effectively have a certain swing range relative to the firing pin seat sleeve 1, so that the firing pin sleeve 20 can float along the radial direction of the firing pin seat sleeve 1, so that when the present invention is in use, not only can the firing pin 2 smoothly enter the firing pin sleeve 20, but also after the firing pin 2 enters the firing pin sleeve 20, the centerline axis of the firing pin 2 is always on the same axis as the center axis of the launching tube 18, so that the firing pin 2 can accurately fire the gunpowder on the integrated nail bullet, making the firing of the firing pin 2 more accurate.

[0057] By providing a limiting step 25 in the firing pin sleeve 20 that cooperates with the needle cap of the firing pin 2, the opening diameter of the rear end of the firing pin sleeve 20 is made larger than the opening diameter of the front end of the firing pin sleeve 20. When the push-type electromagnet 3 strikes the firing pin 2 and moves forward quickly, the limiting step 25 can effectively limit the forward distance of the firing pin 2, which not only ensures that the firing pin 2 can move forward normally, but also effectively prevents the firing pin 2 from moving forward too much, and finally enables the firing pin to accurately fire the integrated nail bullet.

[0058] The firing pin 2 is provided with a firing pin reset spring 26, one end of the firing pin reset spring 26 is pressed against the limiting step 25, and the other end of the firing pin reset spring 26 is pressed against the needle cap of the firing pin 2; a pressure relief hole 21 is also provided on the firing pin sleeve 20. The firing pin reset spring 26 is sleeved on the fired end of the firing pin 2, and the firing pin reset spring 26 can be directly installed in the firing pin sleeve 20, and is pressed against the limiting step 25 of the firing pin sleeve 20, so that the front end of the firing pin reset spring 26 is limited, and the firing pin reset spring 26 is pressed against the firing pin cap on the firing pin 2; by installing the firing pin reset spring 26, after the push-type electromagnet 3 is powered off, the firing pin reset spring 26 can push the firing pin 2 to reset by its own elastic force, thereby preparing for the next work; at the same time, when the iron core of the push-type electromagnet 3 hits the firing pin 2 and moves forward quickly, the firing pin reset spring 26 can apply a buffering force to the firing pin 2, thereby effectively preventing the firing pin 2 from causing damage to the firing pin sleeve 20 due to the excessively fast forward speed.

[0059] The firing pin sleeve 20 has at least one pressure relief hole 21, and the plurality of pressure relief holes 21 are evenly spaced along the circumference of the central axis of the firing pin sleeve 20. By providing the pressure relief hole 21 on the firing pin sleeve 20, after the integrated nail bullet is fired, the heat or air pressure diffused into the gap between the firing pin 2 and the firing pin sleeve 20 can be directly diffused through the pressure relief hole 21 on the firing pin sleeve 20, which not only ensures the pressure balance between the firing pin sleeve 20 and the firing pin 2, but also effectively diffuses the heat in the firing pin sleeve 20.

[0060] The firing base 5 is also installed at the rear end of the firing pin seat 1. The firing base 5 has a limit stop II 12, and the front end of the push electromagnet 3 is pressed against the firing base 5, and the rear end of the push electromagnet 3 is pressed against the limit stop II 12. When the push electromagnet 3 is installed, since the firing pin seat 1 has a firing base 9, the front end of the push electromagnet 3 can be directly limited by the firing base 9; the limit stop II 12 in the firing base 5 is located at the front end of the firing base 5, so that the opening diameter of the front end of the firing base 5 is larger than the opening diameter of the rear end of the firing base 5, so that the inner wall of the firing base 5 is in the shape of a stepped hole. When the push electromagnet 3 needs to be installed, the limit stop II 12 in the firing base 5 can limit the rear end of the push electromagnet 3. By limiting the two ends of the push electromagnet 3, the two ends of the push electromagnet 3 are fixed together, and finally the installation of the push electromagnet 3 is realized. When the push electromagnet 3 needs to be installed, the push electromagnet 3 is first placed into the firing pin sleeve 1. As the firing base 5 and the firing pin sleeve 1 are tightened and fixed, the distance between the limit stop Ⅱ12 and the push electromagnet 3 gradually becomes smaller. When the firing base 5 and the firing pin sleeve 1 are completely tightened, the limit stop Ⅱ12 presses the push electromagnet 3 into the firing pin sleeve 1, which not only enables the push electromagnet 3 to be quickly installed, but also makes the disassembly of the push electromagnet 3 more convenient.

[0061] In this embodiment, the front end of all components and the firing end of the components are both ends of the components close to the launching tube 18 , and the rear end of the components and the fired end of the components are both ends of the components away from the launching tube 18 .

[0062] When the nail shooter needs to work, the integrated nail bullet is first loaded into the launch tube 18, and the front end face of the launch tube 18 is close to the fastened surface of the building. At this time, the launch tube 18 is manually pushed so that the launch tube 18 moves backward synchronously with the reset spring seat 13, so that the reset spring 14 is gradually compressed. When the reset spring 14 is completely compressed, the firing end of the firing pin sleeve 20 contacts the integrated nail bullet, and the switch on the external power supply is turned on, so that the external power supply supplies power to the push electromagnet 3, the push electromagnet 3 is energized, and the iron core of the push electromagnet 3 is pushed out, so that the push electromagnet 3 hits the firing pin 2 forward, so that the firing pin 2 fires the integrated nail bullet, thereby detonating the integrated nail bullet, and finally the nails on the integrated nail bullet are shot into the building matrix to complete the fastening of the nails.

[0063] When the nails on the integrated nail bullet are shot into the building matrix, the switch on the external power supply is turned off to stop the external power supply to the push electromagnet 3, the push electromagnet 3 is powered off, and the iron core of the push electromagnet 3 is reset. When the iron core of the push electromagnet 3 is reset, the firing pin reset spring 26 automatically resets the firing pin 2 through its own thrust. At the same time, the manual force applied to the launching tube 18 is released, the reset spring 14 loses the thrust of the reset spring seat 13, and the reset spring 14 pushes the reset spring seat 13 to reset through its own elastic force, thus completing the preparation for the next construction.

[0064] Since the firing pin 2 in the present application is not connected to the iron core of the push electromagnet 3, and the rear end of the firing pin 2 has a firing seat 9 for limiting, the recoil force generated by the explosion of the integrated nail bullet will not be transmitted to the push electromagnet 3, and the push electromagnet 3 does not need a buffer spring 7 for buffering.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
