[0039] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0040] Reference Figure 1 and Figure 2 In one embodiment of this utility model, the recoil mechanism for a simulated sniper rifle includes a gun shell 1, an outer sleeve 2, an inner sleeve 3, a power assembly 4, a bolt assembly 5, and a barrel 6.

[0041] Reference Figure 2 and Figure 3 The outer sleeve 2 is axially confined within the gun housing 1. Specifically, a fixing ring and a stop ring can be installed inside the gun housing 1, with both ends of the outer sleeve 2 abutting against the fixing ring and the stop ring respectively to axially limit the outer sleeve 2. The inner sleeve 3 is slidably inserted through the outer sleeve 2, and one end of the inner sleeve 3 is provided with an impact head 7 that can be driven by the power assembly 4. In this embodiment, the power assembly 4 includes a coil winding 41 disposed in the outer sleeve 2 and a magnet assembly 42 disposed in the inner sleeve 3. Therefore, by energizing the coil winding 41, it can generate electromagnetic force, which in turn drives the inner sleeve 3 to move through the magnet assembly 42 in the inner sleeve 3, and drives the impact head 7 located at its end to move through the inner sleeve 3.

[0042] Reference Figure 3 and Figure 4The bolt assembly 5 includes a sleeve 51 disposed within the receiver 1 and an impact part 52 connected to the end of the sleeve 51 away from the impact head 7. The impact head 7 includes a first position away from the impact part 52 and a second position passing through the sleeve 51 to contact the impact part 52. The bolt assembly 5 can be operably rotated about its axis to a first rotational position that allows the impact head 7 to move from the first position to the second position. When the recoil mechanism is in the firing state, the bolt assembly 5 is in the first rotational position, and the power unit 4 drives the impact head 7 to impact from the first position to the second position to simulate recoil.

[0043] Reference Figure 1 and Figure 3 The bolt assembly 5 can be operably rotated about its axis to a second rotational position. When the bolt assembly 5 is in the second rotational position, it can be operably moved axially away from the impact head 7 to disengage the impact head 7 from the sleeve 51. When the bolt assembly 5 is in the second rotational position and the impact head 7 is disengaged from the sleeve 51, the bolt assembly 5 can be operably moved axially and abutted against the impact head 7 by the sleeve 51 to drive the impact head 7 to a first position.

[0044] After one firing, the bolt assembly 5 is positioned as follows: Figure 1 In the first rotational position shown, the impact head 7 extends into the sleeve 51 and is located in the second position. At this time, the bolt assembly 5 is adjusted to the second rotational position. Then, the bolt assembly 5 is moved axially away from the impact head 7 to disengage the impact head 7 from the sleeve 51. Next, the bolt assembly 5 is moved axially in the opposite direction, with the sleeve 51 supporting the impact head 7, driving it back to the first position. Finally, the bolt assembly 5 is returned to the first rotational position, putting the recoil mechanism in a firing state. At this point, the power unit 4 can be controlled to drive the impact head 7 from the first position to the second position, simulating recoil. Therefore, the recoil mechanism of this invention for a simulated sniper rifle can adjust the state of the recoil mechanism by adjusting the position of the bolt assembly 5, to replicate the operating logic of a real sniper rifle as closely as possible, ensuring the training effect for trainees.

[0045] Reference Figure 4 In this embodiment, the bolt assembly 5 also includes a handle 53 fixed to the outer periphery of the impact part 52, and the gun housing 1 has a limiting hole 11 for guiding the movement of the handle 53 (e.g., Figure 1 (As shown). The limiting hole 11 may specifically include two sections arranged axially and circumferentially along the sleeve 51, so that the bolt assembly 5 can move axially and rotate about its axis to a first rotation position or a second rotation position. Therefore, by operating the handle 53 along the central path of the limiting hole 11, the trainee can move the sleeve 51 and the impact part 52 to the corresponding positions, thereby simulating the operating logic of a sniper rifle in actual use.

[0046] Reference Figure 3 and Figure 4 In one optional embodiment, the outer wall of the bolt assembly 5 is provided with a locking part 511, and the inner wall of the gun case 1 is provided with a locking groove 12. When the recoil mechanism is in the firing state, the bolt assembly 5 is located in the first rotational position, and the locking part 511 is locked in the locking groove 12. At this time, the bolt assembly 5 can be limited so that the impact head 7 impacts the impact part 52, thereby ensuring the effect of recoil. In this embodiment, when the bolt assembly 5 is located in the second rotational position, the locking part 511 disengages from the locking groove 12. At this time, the bolt assembly 5 can move along its axial direction to facilitate the operation and reset of the recoil mechanism to the firing state.

[0047] Reference Figure 4 and Figure 5 The inner wall of the sleeve 51 is provided with a limiting part 512 and a clearance opening 513 corresponding to the position of the limiting part 512. The impact head 7 includes an abutment part 71 protruding from its peripheral wall. When the bolt assembly 5 is in the first rotation position, the abutment part 71 can move the impact head 7 from the second position to the first position through the clearance opening 513. When the bolt assembly 5 is in the second rotation position and the impact head 7 is dislodged from the sleeve 51, the limiting part 512 can abut against the abutment part 71 to drive the impact head 7 to move to the first position.

[0048] Reference Figure 5 The impact head 7 has a receiving groove 72, and the abutment part 71 is movably connected to the groove wall of the receiving groove 72. When the bolt assembly 5 is in the second rotation position and the impact head 7 is dislodged from the sleeve 51, the limiting part 512 abuts against the abutment part 71 in a circumferential direction so that the abutment part 71 is received into the receiving groove 72.

[0049] Reference Figure 4 and Figure 5 A first elastic element 73 is provided inside the receiving groove 72. The abutment portion 71 is configured as two claws rotatably connected to the inner wall of the receiving groove 72. The first elastic element 73 is located between the two claws and has elastic potential energy to drive the claws away from the receiving groove 72 to protrude from the peripheral wall of the impact head 7. The first elastic element 73 can be configured as a spring. The abutment portion 71 is provided with a bearing surface perpendicular to the center line of the impact head 7 and a guide surface inclined relative to the center line of the impact head 7. The far end of the guide surface relative to the center line of the impact head 7 is adjacent to the end face of the impact head 7. The limiting portion 512 abuts against the bearing surface or the guide surface.

[0050] Therefore, when the bolt assembly 5 moves axially away from the impact head 7, the limiting portion 512 located within the sleeve 51 abuts against the guide surface of the abutment portion 71, thereby driving the two grippers to overcome the elastic force of the first elastic member 73 and be received within the receiving groove 72. This allows the limiting portion 512 within the sleeve 51 to pass through the abutment portion 71, causing the impact head 7 to disengage from the sleeve 51. When the bolt assembly 5 moves axially in the opposite direction and abuts the impact head 7 with the sleeve 51, the limiting portion 512 located within the sleeve 51 abuts against the abutment surface of the abutment portion 71, driving the impact head 7 to return to the first position.

[0051] Reference Figure 1 and Figure 6 The barrel 6 is partially inserted into the gun housing 1. A first magnetic element 81 is provided at the end of the inner sleeve 3 furthest from the bolt assembly 5, and a second magnetic element 82 or a first magnetically attracted element is provided at the end of the barrel 6 closest to the gun housing 1. The first magnetic element 81 and the second magnetic element 82 or the first magnetically attracted element attract each other, thereby confining the impact head 7 to a first position. In this embodiment, the first magnetic element 81 can be made of a magnet to attract the inner sleeve 3 and the barrel 6. In one embodiment, the second magnetic element 82 can also be replaced with a magnetically attracted metal material to attract the inner sleeve 3 and the barrel 6. This application does not impose specific limitations in this regard. Figure 2 In this embodiment, the barrel 6 may specifically include a front barrel 6 in the form of a rod and a rear barrel 6 in the form of a sleeve, with the rear barrel 6 partially inserted into the gun housing 1. (Refer to...) Figure 6 One end of the inner sleeve 3 may be provided with an extension rod, the first magnetic element 81 is fixed to the extension rod, and the extension rod may be inserted into the outer sleeve 2. The second magnetic element 82 or the first magnetically attracted element may be provided at the connection between the rod body and the sleeve body of the barrel 6. When the bolt assembly 5 is moved along its axial direction and the sleeve 51 abuts against the impact head 7, the inner sleeve 3 may move to attract the barrel 6, thereby limiting the impact head 7 to the first position.

[0052] Reference Figure 6 and Figure 7 The recoil mechanism also includes a second elastic element 9, which drives the inner sleeve 3 to move along its axis, causing the impact head 7 to impact from the first position to the second position. The magnetic attraction between the inner sleeve 3 and the barrel 6 is greater than the elastic force applied to the inner sleeve 3 by the second elastic element 9, ensuring that the impact head 7 is confined to the first position. The second elastic element 9 can also be a spring. In this embodiment, the second elastic element 9 and the power component 4 act simultaneously on the inner sleeve 3, driving the inner sleeve 3 to move through both electromagnetic and elastic forces, causing the impact head 7 to impact from the first position to the second position, increasing the recoil force to simulate and reproduce the force of real recoil as closely as possible.

[0053] Reference Figure 6 and Figure 7 Specifically, the second elastic element 9 is configured as a spring sleeved outside the outer sleeve 2. The outer sleeve 2 has an elongated hole 21, the extension direction of which is the same as the axial direction of the outer sleeve 2. The recoil mechanism also includes a retaining ring 10, which is fixed to the inner sleeve 3 by fasteners passing through the elongated hole 21. The two ends of the spring abut against the retaining ring 10 and the barrel 6, respectively. The elongated hole 21 ensures that the inner sleeve 3 can only move along its axial direction and cannot rotate around its axis, thereby ensuring that the abutment portion 71 of the impact head 7 can pass through the clearance opening 513 inside the sleeve 51. At the same time, the length of the elongated hole 21 can further limit the stroke of the inner sleeve 3. In this embodiment, the second elastic element 9 drives the retaining ring 10 to move, thereby driving the inner sleeve 3 to move, and thus causing the impact head 7 to impact from the first position to the second position.

[0054] The operating procedure of the recoil mechanism for simulating a sniper rifle in this application is as follows:

[0055] After a single firing, the bolt assembly 5 is in the first rotating position, and the impact head 7 extends into the sleeve 51 and is in the second position. At this time, the bolt assembly 5 is adjusted to the second rotating position, and then the bolt assembly 5 is moved away from the impact head 7 along its axis. The impact head 7 is dislodged from the sleeve 51 by the action of the limiting part 512 of the sleeve 51 and the abutment part 71 of the impact head 7. Next, the bolt assembly 5 is moved in the opposite direction along its axis, and the limiting part 512 of the sleeve 51 abuts against the abutment part 71 of the impact head 7, so that the other end of the inner sleeve 3 attracts the barrel 6, thereby causing the impact head 7 to return to the first position. Finally, the bolt assembly 5 is returned to the first rotating position, so that the recoil mechanism is in the firing state.

[0056] Upon firing, the power unit 4 is controlled to operate, and in conjunction with the elastic force of the second elastic element 9, the impact head 7 impacts from the first position to the second position, thus simulating recoil. By repeating the above steps, the recoil of a sniper rifle can be simulated.

[0057] Therefore, the recoil mechanism of this utility model for simulating a sniper rifle can adjust the state of the recoil mechanism by operating and adjusting the position of the bolt assembly 5, so as to restore the operating logic of the actual sniper rifle as much as possible and ensure the training effect of the trainees.

[0058] One embodiment of this utility model also discloses a simulated sniper rifle, including the aforementioned recoil mechanism for a simulated sniper rifle. In this embodiment, the simulated sniper rifle may be equipped with a trigger, and pulling the trigger controls the operation of the power unit 4 to simulate recoil. It is understood that the simulated sniper rifle equipped with the aforementioned recoil mechanism can, as far as possible, replicate the operational logic of a real sniper rifle to simulate recoil effects, ensuring the training effectiveness of trainees.

[0059] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
