Description

Technical Field

[0001] This application relates to the field of rifles, and more particularly to a rifle kit and a rifle. Background Technology

[0002] A rifle is a shoulder-fired, long-barreled firearm, typically with a rifled barrel, used to achieve accurate shooting at medium to long ranges by firing fixed ammunition. Modern military rifles mostly employ automatic or semi-automatic feeding and firing mechanisms, and are equipped with detachable magazines, modular rails, and ergonomic designs such as adjustable stocks and grips. A sniper rifle is a type of rifle specifically designed for high-precision, long-range sniping missions, emphasizing extreme accuracy, stability, and long-range ballistic performance.

[0003] The accuracy of a rifle depends not only on the internal manufacturing quality of the barrel and receiver, but also on the combined effects of the structural rigidity of the entire weapon system and the stability of human-machine interaction. On the one hand, if the optical sights, laser designators, and other sighting instruments mounted on the handguard experience slight displacement due to loosening of the connection between the handguard and receiver or deformation caused by heat / stress, it will directly lead to a shift in the aiming reference. On the other hand, the stability of the shooter's grip posture will significantly affect the consistency of muzzle pointing at the moment of firing.

[0004] In summary, rifles in related technologies suffer from low shooting accuracy due to a lack of overall structural stability. Summary of the Invention

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] In the description of this application, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0022] In the description of this application, "multiple" refers to two or more. The use of "first" and "second" is for the purpose of distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or the order in which the technical features are indicated.

[0023] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0024] Reference Figure 1 As shown, a rifle kit includes: a receiver 1000, the front bottom of the receiver 1000 extending forward to form an extension seat 1100, and a slot provided in the extension seat 1100; The handguard 2000 has a first connecting part 2100 at the bottom end that matches the slot. The first connecting part 2100 and the extension seat 1100 are connected by insertion to allow the handguard 2000 to be installed at the front end of the housing 1000. A locking part is used to fix the first connecting part 2100 inside the extension seat 1100; Grip 3100, grip 3100 is mounted on the bottom of receiver 1000; Thumb rest 3200 is mounted above the grip 3100 and fixed to the side wall of the receiver 1000.

[0025] In this embodiment, a first connecting part 2100 is provided at the bottom end of the handguard 2000, and a forward-extending extension seat 1100 is provided at the bottom front end of the receiver 1000. During installation, the handguard 2000 is extended rearward along the barrel, and the first connecting part 2100 is inserted into a slot within the extension seat 1100. The handguard 2000 is installed at the front end of the receiver 1000 via this insertion method, and then the first connecting part 2100 is fixed within the extension seat 1100 by a locking part. This application can improve the stability of the connection between the handguard 2000 and the receiver 1000, avoiding impact on the accuracy of instruments such as optical sights mounted on the handguard 2000. Furthermore, a grip 3100 is provided at the bottom of the receiver 1000, and a thumb rest 3200 is provided on the side of the receiver 1000 above the grip 3100. When the shooter is aiming, his thumb can rest on the thumb rest 3200, so the shooter can half-grip the grip 3100. When the shooter pulls the trigger with his index finger in this half-grip position, the force is straight and backward, which can improve firing accuracy. This application can improve the accuracy of instruments such as optical sights mounted on the handguard 2000, and improve firing accuracy. By constructing a synergistic stability for the overall structure of the rifle, shooting accuracy is improved.

[0026] It should be noted that the stability of the shooter's grip posture significantly affects the consistency of muzzle pointing at the moment of firing. This is because shooters mostly use a full grip posture with their thumb and forefinger covering the grip when aiming and firing. However, when pulling the trigger with the index finger in this full grip posture, the force exerted by the index finger is not straight backward, which affects firing accuracy. Therefore, in this application, a thumb rest 3200 is provided on the side of the receiver 1000 above the grip 3100. When the shooter is aiming, the thumb can rest on the thumb rest 3200, so the shooter can half-grip the grip 3100. When pulling the trigger with the index finger in this half-grip posture, the force exerted is straight backward, which can improve firing accuracy.

[0027] This application constructs the "overall structural synergistic stability" of the rifle from two dimensions: platform structural stability and shooter operation consistency, through the coordinated design of the rigid connection structure of the handguard-receiver and the grip-thumb rest holding mechanism, thereby systematically improving shooting accuracy.

[0028] Specifically, in this application, the end of the handguard 2000 refers to the end away from the barrel and facing the receiver. The bottom of the end of the handguard 2000 has a protruding first connecting portion 2100. The first connecting portion 2100 is inserted into the slot of the extension base 1100 as a connector. The shape of the first connecting portion 2100 and the shape of the slot can be set to any connector shape according to actual needs. For example, in this embodiment, the cross-section of the first connecting portion 2100 is dovetail-shaped, resulting in better stability after insertion.

[0029] It should be noted that in related technologies, the handguard 2000 and the casing 1000 are connected by a common protrusion and groove, but the stability of this connection is not good. In this application, an extension seat 1100 extending forward is provided at the bottom of the front end of the casing 1000. Compared with the protrusion and groove, by providing the extension seat 1100 to be connected with the first connecting part 2100, the mating length can be increased, which greatly improves the stability after the connection.

[0030] In this application, the locking part can be a bolt or other locking component to lock the handguard 2000 to the extension seat 1100. It should be understood that when the locking part is a bolt, the extension seat 1100 and / or the first connecting part 2100 are provided with corresponding screw holes.

[0031] It should be noted that this is to avoid affecting the accuracy of instruments such as optical sights mounted on the handguard 2000, that is, to avoid affecting the accuracy of the handguard 2000 being coaxial with the barrel.

[0032] In some embodiments, the locking part includes a second bolt; refer to Figure 2 As shown, the bottom of the extension base 1100 is provided with a first screw hole 1110, and the bottom of the first connecting part 2100 is provided with a second screw hole 2110 corresponding to the first screw hole 1110. The second bolt fixes the first connecting part 2100 in the extension base 1100 through the first screw hole 1110 and the second screw hole 2110.

[0033] In this embodiment, a first screw hole 1110 is provided at the bottom of the extension base 1100, and a second screw hole 2110 corresponding to the first screw hole 1110 is provided at the bottom of the first connecting part 2100. The first connecting part 2100 can be firmly fixed in the extension base 1100 by the cooperation of the second bolt, the first screw hole 1110 and the second screw hole 2110.

[0034] Specifically, a first screw hole 1110 is provided at the bottom of the extension base 1100. In this embodiment, since a second connecting part 1120 for mounting a bracket is also provided at the bottom of the extension base 1100, and a fourth screw hole 1121 is also provided on the second connecting part 1120, the first screw hole 1110 also extends to the bottom of the second connecting part 1120. The first screw hole 1110 and the fourth screw hole 1121 on the second connecting part 1120 are in different positions to avoid mutual conflict.

[0035] It should be understood that the first screw hole 1110 is a through hole extending vertically, meaning that the first screw hole 1110 passes through the bottom of the second connecting part 1120 into the groove of the extension base 1100, so that the second bolt can pass through the first screw hole 1110 and penetrate into the second screw hole 2110, thereby fixing the first connecting part 2100 to the extension base 1100. The fourth screw hole 1121 can be a blind hole, meaning that the fourth screw hole 1121 does not need to penetrate into the extension base 1100; it only needs to ensure that the first bolt can be inserted.

[0036] For example, in this embodiment, four first screw holes 1110 and four fourth screw holes 1121 are respectively provided on the second connecting part 1120.

[0037] In some embodiments, the locking part includes a third bolt; The extension seat 1100 has a third screw hole 1130 on its side, and the third bolt is used to fix the first connecting part 2100 laterally through the third screw hole 1130.

[0038] In this embodiment, a third screw hole 1130 is provided on the side of the extension seat 1100. The first connecting part 2100 can be fixed laterally by the third bolt extending into the side, which further improves the stability of the structure.

[0039] refer to Figure 1 As shown, in this embodiment, two pairs of third screw holes 1130 are provided on the lower side of both sides of the extension seat 1100. After the third bolt extends laterally into the third screw hole 1130, the gap is locked by the lateral third bolt, so that the housing 1000 and the handguard 2000 have a tighter clamping force, thereby fixing the first connecting part 2100 laterally.

[0040] It should be noted that the first connecting part 2100 can also be fixed laterally in the following way: after the third bolt is inserted, its end abuts against the side of the first connecting part 2100, thereby achieving lateral fixation.

[0041] In some embodiments, the locking part further includes a connecting latch 1300 for securing the upper end of the connection between the handguard 2000 and the housing 1000.

[0042] Specifically, in this embodiment, the connecting latch 1300 is a T-shaped latch, and a slot matching the T-shaped latch is provided on the side wall of the end of the handguard 2000. The front end of the housing 1000 is provided with a third connecting part for extending into the end of the handguard 2000. The T-shaped latch fixes the third connecting part to the end of the handguard 2000 through the slot.

[0043] In this embodiment, by fixing the upper end of the handguard 2000 to the front end of the housing 1000 with a T-shaped locking buckle, the top of the handguard 2000 can also be clamped to the housing 1000, further improving stability.

[0044] Among them, a third protrusion 2200 is provided above the end of the handguard 2000, and a corresponding groove is provided at the front end of the housing 1000. When connecting, the engagement of the third protrusion 2200 with the groove can further improve the stability of the connection between the top of the handguard 2000 and the housing 1000.

[0045] It should be noted that in this embodiment, a guide rail is also provided on the handguard 2000, which can be used to install various types of sights, such as high-magnification scopes. High-magnification aiming requires extremely high precision, and the top of the handguard 2000 can also be clamped to the receiver 1000. This can avoid the possibility of the handguard 2000 and the top of the receiver 1000 becoming loose, ensure the accuracy of the handguard and the barrel being coaxial, and further enhance stability.

[0046] For details, please refer to Figure 3 As shown, in this embodiment, the thumb rest 3200 is located on the side of the end of the receiver 1000 of the rifle and directly above the grip 3100 mounting position. The thumb rest 3200 can be directly fixed to the rifle, or it can be a detachable accessory, for example, by opening a screw hole at the mounting position and fixing the thumb rest 3200 with bolts.

[0047] The thumb rest 3200 can be installed on both sides of the rifle to accommodate users with different dominant hands; of course, the detachable thumb rest 3200 can also be installed on the left or right side of the rifle as needed.

[0048] In this embodiment, the grip 3100 may be a straight grip, an angled grip, or a grip with other specific functions.

[0049] In some embodiments, there are two thumb rests 3200, which are mounted opposite each other on both sides of the rifle.

[0050] In this embodiment, two thumb rests 3200 are respectively set on both sides of the rifle. Whether the left or right hand is holding the grip, the thumb can rest on the thumb rest 3200, which can meet the needs of users with different dominant hands at the same time. There is no need to disassemble the thumb rest 3200, which improves convenience.

[0051] In some embodiments, the housing 1000 has an elongated mounting groove 1400, and the thumb support 3200 includes a support platform and a locking member. The locking member is used to fix the support platform on the mounting groove 1400, and the tilt angle and front and rear position of the support platform in the mounting groove 1400 can be adjusted by the locking member.

[0052] In this embodiment, the housing 1000 has an elongated mounting slot 1400. The tilt angle and front-to-back position of the support in the mounting slot 1400 can be adjusted by a locking component. This allows for adjustment of the angle and front-to-back position of the thumb support 3200, further improving adaptability and meeting the personalized needs of different users.

[0053] Specifically, in this embodiment, the locking element is a bolt. A screw hole is provided at the bottom of the support platform. The bolt is threaded into the screw hole to fix the support platform on the bolt, and the bolt is fixed in the mounting groove 1400 by a nut.

[0054] It should be understood that before fixing with nuts, the tilt angle of thumb support 3200 can be adjusted by rotating the support or bolts. Since the mounting groove 1400 is elongated, the bolts can drive the support to move back and forth along the mounting groove 1400. Once it has moved to the appropriate position and rotated to the appropriate angle, the bolts can be fixed with nuts to complete the adjustment of the angle and back and forth position of thumb support 3200.

[0055] In some embodiments, the surface of the thumb rest 3200 is provided with anti-slip texture.

[0056] In this embodiment, anti-slip textures are provided on the surface of the thumb support 3200 to improve stability when the thumb makes contact.

[0057] In this embodiment, the grip 3100 can be a straight grip, a slanted grip, or a grip with a special structure to meet the gripping needs of different users.

[0058] refer to Figure 4 and Figure 5 As shown, in some embodiments, a stock 6000 is also included at the end of the receiver 1000. A support rod adjustment mechanism 4000 is provided on the stock 6000. The support rod adjustment mechanism 4000 includes: Support rod 4100, with a first spring 4110 at the top of support rod 4100; The first limiting lock block 4200 has a first through hole 4210 in the middle area, the support rod 4100 is located in the first through hole 4210, and the first side wall of the first limiting lock block 4200 is provided with a second spring 4220. The first adjustment button 4300 is connected to the second side wall of the first limiting lock block 4200. The second side wall and the first side wall are two opposite side walls of the first limiting lock block 4200. The first adjustment button 4300 is used to switch the first limit locking block 4200 between the adjustment position and the locking position. When the first limit locking block 4200 is in the adjustment position, the support rod 4100 can move up and down along the first opening 4210. When the first limit locking block 4200 is in the locking position, the first limit locking block 4200 locks the support rod 4100.

[0059] In this embodiment, a limiting lock block 4200 is provided on the support rod 4100, and an adjustment button 4300 is provided on the limiting lock block 4200. When the adjustment button 4300 is pressed, the limiting lock block 4200 is in the adjustment position. At this time, the support rod 4100 is in the middle position of the opening and is quickly ejected downward by a downward elastic force from the top first spring 4110, allowing for rapid adjustment of the height of the support rod 4100. When the adjustment button 4300 is released, the limiting lock block 4200 is engaged in the locking position by a reverse elastic force from the side wall second spring, locking the support rod 4100. This application enables rapid adjustment of the height of the support rod 4100, improving stability during support.

[0060] Specifically, in this embodiment, the support rod adjustment mechanism is installed inside the stock 6000, and a mounting cavity is opened inside the stock 6000. The bottom of the mounting cavity is open to the outside, so that the support rod 4100 can extend from the bottom of the mounting cavity.

[0061] Specifically, the first spring 4110 is an inner tube spring, the top end of the support rod 4100 is provided with a mounting groove, the lower end of the first spring 4110 is set in the mounting groove, and the upper end of the first spring 4110 abuts against the top wall of the mounting cavity, thereby giving the support rod 4100 a downward elastic force.

[0062] In this embodiment, the first limiting lock block 4200 adopts a square structure, but other shapes can also be used. A first through-hole 4210 is provided in the middle area of ​​the first limiting lock block 4200. The support rod 4100 is located inside the first through-hole 4210 and extends from below it. A second spring 4220 is provided on the first sidewall of the first limiting lock block 4200. The second spring 4220 abuts against the inner sidewall of the mounting cavity, providing a lateral elastic force to the first limiting lock block. A first adjustment button 4300 is connected to the second sidewall of the first limiting lock block 4200. Since the first and second sidewalls are opposite sidewalls, when the first adjustment button 4300 is pressed, the first limiting lock block 4200 moves inward to compress the second spring 4220. At this time, the first limiting lock block 4200 is in the adjustment position. When the first adjustment button 4300 is released, the first limit lock block 4200 moves outward due to the rebound force of the second spring 4220, and at this time the first limit lock block 4200 is in the locked position.

[0063] It should be understood that when in the adjustment position, the support rod 4100 is precisely located on the central axis of the first opening 4210. At this time, the support rod 4100 does not contact the inner wall of the first opening 4210 or experiences minimal friction, allowing it to move up and down along the first opening 4210. Furthermore, when moving from the locked position to the adjustment position, the support rod 4100 will rapidly spring downwards due to the downward force of the first spring 4110. The shooter can then adjust the height of the support rod 4100 by pressing it against the ground and simultaneously raising or lowering the stock, or by pressing the first adjustment button 4300 with one hand and holding the support rod 4100 with the other. After adjustment, releasing the first adjustment button 4300 causes the first limit locking block 4200 to enter the locked position under the action of the second spring 4220. At this time, the inner wall of the first opening 4210 abuts against the support rod 4100, increasing friction and preventing the support rod 4100 from moving up and down, thus achieving locking. Therefore, this application can achieve rapid adjustment of the height of the support rod 4100, and after the height is adjusted, the support rod 4100 can be firmly limited to the current height, thereby achieving rapid adjustment of the support rod height 4100 degrees and improving the stability during support.

[0064] In some embodiments, the support rod 4100 is provided with an external thread, and the inner wall of the first opening 4210 is provided with an internal thread that matches the external thread. Specifically, in this embodiment, a limiting tooth is provided in the first opening 4210, and the internal thread is provided on the limiting tooth. When the limiting tooth abuts against the support rod 4100 but is not locked, it is equivalent to the support rod 4100 being threadedly connected to the limiting tooth. By rotating the support rod 4100, fine adjustment of the height can be achieved, further improving the flexibility of adjustment.

[0065] In practical applications, the shooter can first press the first adjustment button 4300 to quickly make a coarse adjustment of the height, and then make a fine adjustment of the height by rotating the support rod 4100, so as to find the most suitable height.

[0066] In some embodiments, an adjusting ring 4120 is fixed at the upper part of the bottom end of the support rod 4100, and the adjusting ring 4120 rotates synchronously with the support rod 4100.

[0067] In this embodiment, an adjusting ring 4120 is provided at the upper part of the bottom of the support rod 4100. The synchronous rotation of the adjusting ring 4120 and the support rod 4100 means that the adjusting ring 4120 and the support rod 4100 are fixedly connected. Therefore, rotating the adjusting ring 4120 will synchronously rotate the support rod 4100, thereby allowing the support rod 4100 to move up and down by means of thread adjustment.

[0068] In some embodiments, the bottom end of the support rod 4100 is connected to a support base 4130.

[0069] In this embodiment, a support base 4130 is provided at the bottom end of the support rod 4100 to give the support rod 4100 better stability when it touches the ground.

[0070] Specifically, the support base 4130 is also equipped with anti-slip texture, which can further improve the stability when supporting the ground.

[0071] In some embodiments, the support base 4130 is connected to the bottom end of the support rod 4100 via a bearing 4140.

[0072] In this embodiment, the support base 4130 is connected to the bottom end of the support rod 4100 via a bearing 4140. Therefore, the support base 4130 and the support rod 4100 can rotate asynchronously. That is, when the rotating adjusting ring 4120 drives the support rod 4100 to rotate to adjust the height, the support base 4130 can still be supported on the ground. The height of the support rod 4100 can be adjusted while it is supported, without having to lift the support rod 4100, further improving the flexibility and convenience of height adjustment.

[0073] Specifically, in this embodiment, the bottom end of the support rod 4100 is connected to the support base 4130 through a bearing 4140, a bearing base, and a rubber pad.

[0074] In some embodiments, a screw hole is provided on the second side wall, which communicates with the first opening 4210, and a screw that mates with the screw hole is connected to the first adjustment button 4300.

[0075] In this embodiment, a screw hole is provided on the second side wall, and the first adjustment button 4300 is connected to the first limiting lock block 4200 by means of a screw engaging with the screw hole. Furthermore, since the screw hole communicates with the first opening 4210, when the first adjustment button 4300 is continuously rotated, the end of the screw can extend from the end of the screw hole into the first opening 4210 and abut against the support rod 4100, thereby further fixing the support rod 4100 and further improving stability.

[0076] refer to Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments, a stock 6000 is also included at the end of the receiver 1000. A cheek rest adjustment mechanism 5000 is provided on the stock 6000. The cheek rest adjustment mechanism 5000 includes: Cheek rest 5100, with an adjustment rod 5110 vertically installed at the bottom of the cheek rest 5100; Mounting bracket 5200 is mounted on stock 6000. Mounting bracket 5200 has a mounting cavity 5210 inside and a second opening communicating with mounting cavity 5210 is opened on top of mounting bracket 5200. The second limiting lock block 5300 is installed inside the mounting bracket 5200. The top of the second limiting lock block 5300 is provided with a third opening 5311. The lower end of the adjusting rod 5110 passes through the second opening and the third opening 5311 in sequence and extends into the second limiting lock block 5300. The second adjustment button 5400 is connected to the side wall of the second limit locking block 5300 to switch the second limit locking block 5300 between the adjustment position and the locking position. When the second limit lock block 5300 is in the adjustment position, the adjustment rod 5110 can move up and down to adjust the height; when the second limit lock block 5300 is in the locking position, the second limit lock block 5300 locks the adjustment rod 5110.

[0077] In this embodiment, an adjusting rod 5110 is provided at the bottom of the cheek rest 5100. The lower end of the adjusting rod 5110 passes through the first opening on the mounting bracket and the second opening on the second limiting lock block 5300 and extends into the second limiting lock block 5300. The second limiting lock block 5300 is switched between an adjusting position and a locking position via a second adjusting button 5400. When the second limiting lock block 5300 is in the adjusting position, the adjusting rod 5110 can move up and down to adjust the height of the cheek rest 5100. After adjusting to a suitable height, the second limiting lock block 5300 is moved to the locking position via the second adjusting button 5400, at which point the second limiting lock block 5300 locks the adjusting rod 5110. This application can achieve precise adjustment of the height of the cheek rest 5100, meet the personalized needs of different shooters, and improve aiming comfort and shooting consistency.

[0078] Specifically, in this embodiment, an adjusting rod 5110 is vertically provided at the bottom of the cheek pad 5100. This means that the bottom of the cheek pad 5100 is fixed to the top of the adjusting rod 5110. In this embodiment, a screw hole is provided at the bottom of the cheek pad 5100, and the adjusting rod 5110 is set as a threaded rod. The cheek pad 5100 is fixed to the adjusting rod 5110 by means of threaded connection. The height of the cheek pad 5100 can be adjusted by vertically moving the adjusting rod 5110.

[0079] Specifically, in this embodiment, the mounting bracket 5200 can be installed on the stock 6000 as an additional accessory, or it can be directly integrated into the stock 6000. In this embodiment, the mounting bracket 5200 is directly placed inside the stock 6000, that is, the mounting bracket 5200 is part of the main body of the stock 6000. A mounting cavity 5210 for accommodating the second limiting locking block 5300 is formed inside the mounting bracket 5200. The shape and size of the mounting cavity 5210 match the second limiting locking block 5300, and the second limiting locking block 5300 is located inside the mounting cavity 5210.

[0080] It should be noted that the top of the mounting bracket 5200 has a second opening that communicates with the mounting cavity 5210, and the top of the second limiting lock block 5300 has a third opening 5311. This is so that when the second limiting lock block 5300 is located inside the mounting cavity 5210, the adjusting rod 5110 can pass through the second opening and the third opening 5311 in sequence and extend into the second limiting lock block 5300. It should be understood that when the second limiting lock block 5300 is located inside the mounting cavity 5210, the second opening and the third opening 5311 are aligned.

[0081] The aforementioned second adjustment button 5400 is connected to the side wall of the second limit locking block 5300 to switch the second limit locking block 5300 between the adjustment position and the locking position. This means that by operating the second adjustment button 5400, the second limit locking block 5300 can be in either the adjustment position or the locking position. The second limit locking block 5300 can use a snap-on, latching, or other methods to lock or unlock the adjustment rod 5110. For example, a locking mechanism can be provided inside the second limit locking block 5300. When the second adjustment button 5400 is pressed once, the locking mechanism unlocks, allowing the adjustment rod 5110 to move up and down. When the second adjustment button 5400 is pressed again or released, the locking mechanism locks, securing the adjustment rod 5110.

[0082] For example, the adjustment process of this application is as follows: The shooter presses the second adjustment button 5400 with one hand, at which point the second limit lock block 5300 is in the adjustment position. The shooter then holds the cheek rest 5100 with the other hand and moves it up and down to adjust it to a suitable height. After that, the shooter releases the second adjustment button 5400, causing the second limit lock block 5300 to enter the locking position and lock the adjustment rod 5110. Within the allowable length range of the adjustment rod 5110, any height adjustment can be achieved, with high adjustment accuracy and convenient operation. This application can achieve precise adjustment of the cheek rest height, meeting the personalized needs of different shooters and improving aiming comfort and shooting consistency.

[0083] In some embodiments, the sidewall of the cheek rest 5100 is provided with a first inclined surface and a second inclined surface from top to bottom, and the angle between the second inclined surface and the horizontal direction is greater than the angle between the first inclined surface and the horizontal direction.

[0084] In this embodiment, the sidewall of the cheek rest 5100 is provided with a first inclined surface and a second inclined surface from top to bottom. The angle between the second inclined surface and the horizontal direction is greater than the angle between the first inclined surface and the horizontal direction, which can better fit the shooter's face and improve shooting comfort and stability.

[0085] The angle between the second inclined plane and the horizontal direction is greater than the angle between the first inclined plane and the horizontal direction. This means that the inclination of the first inclined plane is less than that of the second inclined plane. If the inclination is too large, for example, if part of the cheek rest side is almost perpendicular to the horizontal plane, then the shooter's cheek and cheekbone will not be able to fully fit against the cheek rest when the buttstock is against the shoulder, resulting in low comfort. This application, by setting the first and second inclined planes with different inclination angles, that is, designing the cheek rest 5100 into a trapezoidal shape, can ensure that the shooter's cheek and cheekbone are fully fitted against the cheek rest, improving shooting comfort and stability.

[0086] In some embodiments, the second limiting lock block 5300 includes a slide housing 5310 with a single-sided opening and a slider 5320. The second adjusting button 5400 is connected to the first side of the slider 5320 via a connecting rod 5410. A third spring 5330 is provided between the second side of the slider 5320 and the inner wall of the slide housing 5310. A third opening 5311 is provided on the top of the slide housing 5310. The slider 5320 is provided with a limiting groove 5321 that matches the adjusting rod 5110.

[0087] In this embodiment, a second limiting lock block 5300 is constructed by a sliding housing 5310, a slider 5320 and a third spring 5330. The structure is simple, easy to assemble and disassemble and has high reliability.

[0088] Specifically, the slide housing 5310 is fixed in the mounting cavity 5210 by bolts. The first side of the slider 5320 refers to the side facing the second adjustment button 5400. The second adjustment button 5400 is connected to the first side of the slider 5320 through the connecting rod 5410. The second adjustment button 5400 can drive the slider 5320 to move back and forth. A third spring 5330 is provided between the second side of the slider 5320 and the inner wall of the slide housing 5310. Therefore, when the second adjustment button 5400 is pressed, the slider 5320 can move inward and squeeze the third spring 5330 at the same time. At this time, the limiting groove 5321 on the slider 5320 is disengaged from the adjusting rod 5110, the second limiting lock block 5300 is in the adjustment position, and the adjusting rod 5110 can move up and down. When the second adjustment button 5400 is released, the compressed third spring 5330 gives the slider 5320 a reverse thrust, causing the lower end of the adjustment rod 5110 to enter the limiting groove 5321 and be locked in place by the limiting groove 5321.

[0089] For example, in this embodiment, the limiting groove 5321 adopts a semi-circular structure, which can precisely hold the cylindrical adjusting rod 5110. In this embodiment, the third spring 5330 is sleeved on the end of the adjusting rod 5110 and abuts against the second side.

[0090] In some embodiments, the slider 5320 has a threaded hole that extends from the first side to the second side and runs through the front and back, and the connecting rod 5410 has a thread that matches the threaded hole.

[0091] In this embodiment, a through-hole is provided on the slider 5320. When the second adjustment button 5400 is rotated, the slider 5320 can be controlled to move forward or backward along the connecting rod 5410 and maintain its current position. That is, even if the shooter releases the second adjustment button 5400, the adjustment position or the locking position can be locked, which avoids the second adjustment button 5400 being accidentally touched when aiming, causing the height of the cheek rest 5100 to change, and can further improve reliability.

[0092] In some embodiments, there are two adjustment rods 5110, which are respectively located at the front end and rear end of the bottom of the cheek rest 5100.

[0093] In this embodiment, by setting an adjustment rod 5110 at the front end and the rear end respectively to support the cheek resting plate 5100, the stability of the structure can be improved and shaking can be avoided when applying the cheek resting plate.

[0094] It should be understood that setting two adjustment rods 5110 is only one preferred embodiment of this application, and three, four or more adjustment rods 5110 may also be provided to support the cheek rest 5100.

[0095] In some embodiments, the mounting bracket 5200 is provided with a groove 5220 for placing adjustment tools.

[0096] In this embodiment, a groove 5220 is provided on the mounting bracket 5200, in which the rifle adjustment tool can be placed. This way, the shooter does not need to carry the adjustment tool separately, and it does not take up extra space, thus improving convenience.

[0097] For example, in this embodiment, the shape of the groove 5220 matches that of an L-shaped wrench, allowing an L-shaped wrench to be placed within the groove 5220. It should be noted that in some applications of sniper rifles, an L-shaped wrench is needed to assemble or disassemble bipods and other accessories. Since these parts are small and easily lost, and require additional storage bags, this application directly creates a groove 5220 on the mounting bracket 5200 of the stock 6000 to accommodate the L-shaped wrench, eliminating the need for extra space and reducing the probability of loss.

[0098] In some embodiments, a magnet is provided in the groove 5220 for adsorbing adjustment tools made of metal.

[0099] Specifically, in this embodiment, a circular magnet mounting groove 5221 is opened in the middle area of ​​the groove 5220, and the circular magnet is fixed in the magnet mounting groove 5221. In this way, the steel L-shaped wrench can be firmly attracted in the groove 5220 when it is placed in the groove, further reducing the probability of loss.

[0100] refer to Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the receiver 1000 has a first connection port 1200 at its end, and the rifle kit also includes: The stock 6000 has a second connector 6210 at its front end. The intermediate connector 6300 includes a left folding mechanism and a right folding mechanism. The front end of both the left folding mechanism and the right folding mechanism is provided with a first connector 6310 that can be detachably connected to the first connection port 1200. The rear end of both the left folding mechanism and the right folding mechanism is provided with a second connector 6320 that can be detachably connected to the second connection port 6210. Specifically, when the left folding mechanism is installed between the stock 6000 and the receiver 1000, the stock 6000 switches between left folding mode and unfolded mode via the left folding mechanism; when the right folding mechanism is installed between the stock 6000 and the receiver 1000, the stock 6000 switches between right folding mode and unfolded mode via the right folding mechanism.

[0101] In this embodiment, a replaceable intermediate connector 6300 is provided between the stock 6000 and the receiver 1000. Both the left-folding and right-folding mechanisms of the intermediate connector 6300 can be installed between the stock 6000 and the receiver 1000 via a first connector 6310 at the front end and a second connector 6320 at the rear end. When the left-folding mechanism is installed between the stock 6000 and the receiver 1000, the stock 6000 can achieve a left-folded mode and an unfolded mode. When the right-folding mechanism is installed between the stock 6000 and the receiver 1000, the stock 6000 can achieve a right-folded mode and an unfolded mode. By configuring a replaceable intermediate connector 6300, this application enables adjustment of the stock folding direction, improving flexibility.

[0102] Specifically, the detachable connection between the first connector 1200 and the first connector 6310 can be achieved by either plugging in or by using bolts for snap-fit ​​connection.

[0103] It should be noted that in this embodiment, the left folding mechanism and the right folding mechanism are two separate intermediate connecting parts, both of which can be installed between the stock 6000 and the receiver 1000. When the left folding mechanism is installed between the stock 6000 and the receiver 1000, its front end first connector 6310 is fixed to the first connection port 1200 of the receiver 1000, and its rear end second connector 6320 is fixed to the second connection port 6210 of the stock 6000. (Reference) Figure 8 As shown, when the intermediate connector 6300 is selected to use the left folding mechanism, the stock 6000 can be folded to the left side of the rifle via the left folding mechanism. Similarly, when the right folding mechanism is installed between the stock 6000 and the receiver 1000, its front first connector 6310 is fixed to the first connection port 1200 of the receiver 1000, and its rear second connector 6320 is fixed to the second connection port 6210 of the stock 6000. (Refer to...) Figure 9As shown, when the intermediate connector 6300 is selected with a right-folding mechanism, the stock 6000 can be folded to the right side of the rifle via the right-folding mechanism. Different users can choose different intermediate connectors according to their own habits. For example, left-handed and right-handed users have different shooting postures and dominant hands, so they need to choose the left-folding mode or the right-folding mode accordingly to improve shooting accuracy.

[0104] refer to Figure 10 As shown, the intermediate connector 6300 can be deployed in either the left or right folding mechanism. It should be understood that in the deployed mode, the stock 6000 is located at the rear of the rifle and on its central axis. The shooter can improve shooting accuracy by using the stock to brace against the rifle.

[0105] It should be noted that in this embodiment, the left folding mechanism and the right folding mechanism can use structurally similar and symmetrically designed components to achieve folding in different directions. Alternatively, different structural components can be used to achieve folding in both directions.

[0106] In some embodiments, the left-folding mechanism includes a first mounting portion 6330, a first folding limiting portion 6340, a first unfolding limiting portion 6350, a first left limiting portion 6360, and a first right limiting portion 6370; the first mounting portion 6330 has a mounting cavity, a first opening 6331 communicating with the mounting cavity is opened at the top of the first mounting portion 6330, and a second opening 6332 communicating with the mounting cavity is opened on the side of the first mounting portion 6330; the first left limiting portion 6360 is rotatably connected to one end of the first mounting portion 6330 via a first pivot 6361, and the first right limiting portion 6370 is rotatably connected to the other end of the first mounting portion 6330 via a second pivot 6371; a first connector 6310 is fixed on the first left limiting portion 6360, and a second connector 6320 is fixed on the first right limiting portion 6370; In the left-folding mode, the first mounting part 6330 rotates relative to the first left limiting part 6360 via the first pivot 6361, and the first right limiting part 6370 rotates relative to the first mounting part 6330 via the second pivot 6371, so that the stock 6000 folds to the left side of the receiver 1000, and the first left limiting part 6360 and the first right limiting part 6370 are limited in the left-folding mode by the first folding limiting part 6340; In the unfolded mode, the first mounting part 6330 rotates relative to the first left limiting part 6360 via the first pivot 6361, and the first right limiting part 6370 rotates relative to the first mounting part 6330 via the second pivot 6371, so that the stock 6000 unfolds to the end of the receiver 1000. The first left limiting part 6360 and the first right limiting part 6370 are limited in the unfolded mode by the first unfolding limiting part 6350. And / or; the right-folding mechanism includes a second mounting part, a second folding limiting part, a second unfolding limiting part, a second left limiting part, and a second right limiting part; the second mounting part has a mounting cavity, a third opening communicating with the mounting cavity is opened at the top of the second mounting part, a fourth opening communicating with the mounting cavity is opened on the side of the second mounting part, the second left limiting part is rotatably connected to one end of the second mounting part through a third rotating shaft, and the second right limiting part is rotatably connected to the other end of the second mounting part through a fourth rotating shaft; the first connector 6310 is fixed on the second left limiting part, and the second connector 6320 is fixed on the second right limiting part; In the right-folding mode, the second mounting part rotates relative to the second left limiting part via the third pivot, and the second right limiting part rotates relative to the second mounting part via the fourth pivot, so that the stock 6000 folds to the right side of the receiver 1000, and the second left limiting part and the second right limiting part are limited in the right-folding mode by the second folding limiting part; In the unfolded mode, the second mounting part rotates relative to the second left limiting part via the third pivot, and the second right limiting part rotates relative to the second mounting part via the fourth pivot, so that the stock 6000 unfolds to the end of the receiver 1000. The second left limiting part and the second right limiting part are limited in the unfolded mode by the second unfolding limiting part.

[0107] In this embodiment, a linkage folding mechanism is formed by the first mounting part 6330, the first folding limit part 6340, the first unfolding limit part 6350, the first left limit part 6360 and the first right limit part 6370, and a linkage folding mechanism is formed by the second mounting part, the second folding limit part, the second unfolding limit part, the second left limit part and the second right limit part, which can improve the grip effect after folding.

[0108] The folding principle of this application will be explained in detail below using the left-folding mechanism as an example: refer to Figure 11 and Figure 12 As shown, in this embodiment, the first connector 6310 consists of two protrusions and screw holes on the first right limiting part 6370, and the second connector 6320 consists of two protrusions and screw holes on the first left limiting part 6360. The first left limiting part 6360 is fixedly connected to the stock 6000 by two protrusions and bolts, and the first right limiting part 6370 is fixedly connected to the receiver 1000 by two protrusions and bolts.

[0109] It should be noted that in this embodiment, the first mounting part 6330 serves as the mounting bracket for the remaining components in the left folding mechanism. Its interior is a hollow mounting cavity, with a first opening 6331 at the top communicating with the mounting cavity and a second opening 6332 at the front communicating with the mounting cavity. The first folding limiting part 6340 is located at the first opening 6331, and the first unfolding limiting part 6350 is located at the second opening 6332. A first rotating shaft 6361 and a... are respectively provided at both ends of the first mounting part 6330. The second pivot 6371 allows one end of the first left limiting part 6360 and the first mounting part 6330 to rotate relative to each other, and the other end of the first right limiting part 6370 and the first mounting part 6330 to rotate relative to each other. When the first left limiting part 6360 and the first right limiting part 6370 rotate to a position perpendicular to the first mounting part 6330, the stock 6000 is in a left-folded state, and at this time the stock 6000 is located on the left side of the receiver 1000. Figure 10 As shown, when the first left limiting part 6360, the first right limiting part 6370 and the first mounting part 6330 are located on the same central axis, the stock 6000 is in the unfolded state, and at this time the stock 6000 is located at the rear end of the receiver 1000.

[0110] In this embodiment, the function of the first folding limiting part 6340 is to extend from the first opening 6331 in the folded state to limit the first left limiting part 6360 and the first right limiting part 6370, thus maintaining the stability of the folded state. In the unfolded state, the first folding limiting part 6340 retracts into the mounting cavity. Similarly, the function of the first unfolding limiting part 6350 is to limit the first opening 6332 in the unfolded state, and it can also release the limiting state by temporarily retracting into the mounting cavity, so that the first left limiting part 6360 and the first right limiting part 6370 can be rotated through the pivot to enter the folded state.

[0111] Specifically, in this embodiment, the first folding limiting part 6340 includes a T-shaped structural member and a spring. The spring is located at the bottom of the T-shaped structural member, thereby giving the T-shaped structural member an upward elastic force. In the unfolded state, the first opening 6331 is covered by the first left limiting part 6360 and the first right limiting part 6370. At this time, the T-shaped structural member is squeezed and contracted into the mounting cavity by the first left limiting part 6360 and the first right limiting part 6370. When the stock 6000 enters the left folded state from the unfolded state, the first opening 6331 is exposed as the first left limiting part 6360 and the first right limiting part 6370 rotate. At this time, the T-shaped structural member pops out by the rebound force of the bottom spring. The limiting block at the upper end of the T-shaped structural member is located between the first left limiting part 6360 and the first right limiting part 6370, limiting the first left limiting part 6360 and the first right limiting part 6370.

[0112] Specifically, in this embodiment, the first unfolding limiting part 6350 is button-shaped. A spring is provided at the end of the first unfolding limiting part 6350, and the spring abuts against the inner wall of the mounting cavity, thereby giving the first unfolding limiting part 6350 an outward elastic force. A first protrusion 6351 and a second protrusion 6352 are respectively provided at both ends of the front side of the first unfolding limiting part 6350. A first latch 6362 corresponding to the first protrusion 6351 is provided on the first left limiting part 6360, and a second latch 6372 corresponding to the second protrusion 6352 is provided on the first right limiting part 6370. (Reference) Figure 10 As shown, in the unfolded state, the first protrusion 6351 of the first unfolding limiting part 6350 engages with the first latch 6362, and the second protrusion 6352 engages with the second latch 6372, thereby limiting the first left limiting part 6360 and the first right limiting part 6370. At this time, the first left limiting part 6360 and the first right limiting part 6370 cannot rotate, and the first unfolding limiting part 6350 maintains this limiting state through the elastic force provided by the end spring. When folding is required, by pressing the first protrusion 6351 and the second protrusion 6352, the first protrusion 6351 and the second protrusion 6352 are disengaged from the first latch 6362 and the second latch 6372. At this time, the limiting state is released, and the first left limiting part 6360 and the first right limiting part 6370 can rotate to enter the folded state.

[0113] It should be noted that in related technologies, the folding mechanism of the rifle stock is prone to loosening, and a protruding folding pivot is set on one side of the rifle. Since the folding pivot is on one side, it can easily get stuck in the shooter's hand, affecting the shooter's shooting. The linkage folding mechanism adopted in this embodiment does not have a protruding folding pivot that affects the grip and will not affect the shooter's shooting, thus improving the grip effect after folding.

[0114] It should be noted that in this embodiment, the right folding mechanism is a symmetrical structure of the left folding mechanism. Therefore, the component types and folding principles of the right folding mechanism are the same as those of the left folding mechanism, only the folding direction is reversed. The folding process and specific structure of the right folding mechanism will not be described in detail.

[0115] In some embodiments, the intermediate connector 6300 further includes a direct-drive connection mechanism 6380, which includes a connecting frame 6381, a first connector 6310 fixed to the front end of the connecting frame 6381, and a second connector 6320 fixed to the rear end of the connecting frame 6381.

[0116] In this embodiment, by adding a direct-drive connection mechanism 6380 as a replaceable intermediate connector 6300, the direct-drive connection mechanism 6380 can be directly installed in scenarios where there is no need for folding, thereby reducing weight.

[0117] refer to Figure 13 As shown, the direct-drive connection mechanism 6380 includes a rectangular connecting frame 6381. The front end of the connecting frame 6381 has two protrusions and a screw hole as a first connector 6310, and the rear end also has two protrusions and a screw hole as a second connector 6320. The direct-drive connection mechanism 6380 can directly and securely connect the stock 6000 to the receiver 1000. Compared to left-folding and right-folding mechanisms, the direct-drive connection mechanism 6380 has a simpler structure and significantly reduced weight. This weight reduction not only reduces the burden during carrying but also improves maneuverability and shooting stability.

[0118] In some implementations, the grip 3100 may include: A grip bracket 3110 is fixed to the bottom of the housing 1000, and a first mounting hole 3111 is provided on the grip bracket 3110. The grip housing 3120 has a sliding groove 3121 inside, and the grip bracket 3110 is located in the sliding groove 3121. The grip housing 3120 can move back and forth relative to the grip bracket 3110 through the sliding groove 3121. The grip housing 3120 has a second mounting hole 3122 at the position corresponding to the first mounting hole 3111. The length of the second mounting hole 3122 is greater than that of the first mounting hole 3111. Bolts, which pass through the second mounting hole 3122 and the first mounting hole 3111, secure the grip housing 3120 to the grip bracket 3110.

[0119] In this embodiment, the grip, which is composed of the grip bracket 3110, the grip housing 3120 and the bolts, can be adjusted in the front and back position. It can meet the gripping needs of different users without changing the grip, which greatly improves its applicability.

[0120] For details, please refer to Figure 14 , Figure 15 and Figure 16 As shown, the grip support 3110 is an L-shaped support structure. The grip support 3110 is connected to the bottom of the rifle in the same way as a conventional grip. The grip housing 3120 includes two symmetrically arranged housings, which are installed on the grip support 3110 by snap-fit. A groove 3121 is provided in the grip housing 3120 to accommodate the grip support 3110. The height of the groove 3121 is the same as that of the grip support 3110, and the width is greater than that of the grip support 3110. Therefore, the grip housing 3120 can move back and forth relative to the grip support 3110 through the groove 3121, thereby changing the front and back position of the grip housing 3120 on the bottom of the rifle.

[0121] In this embodiment, two first mounting holes 3111 are provided on the grip bracket 3110, and two corresponding strip-shaped second mounting holes 3122 are also provided on the grip housing 3120. It should be understood that the length of the second mounting holes 3122 is adapted to the movable distance of the grip housing 3120. After the grip housing 3120 is adjusted to a suitable position, bolts are passed through the first mounting holes 3111 and the second mounting holes 3122 in sequence to fix the grip housing 3120 to the grip bracket 3110.

[0122] refer to Figure 2 As shown, in some embodiments, the bottom of the extension base 1100 is provided with a second connecting part 1120, which is used to install the legs.

[0123] In this embodiment, by providing a second connecting part 1120 at the bottom of the extension base 1100, the tripod can be installed through the second connecting part 1120, and the tripod can be quickly installed when needed without carrying additional interface accessories.

[0124] It should be understandable that, for reference Figure 18 As shown, mounting a bipod on a rifle can further improve shooting accuracy in specific scenarios. The tripod 7000 can be used, which not only improves shooting stability but also allows for flexible aiming maneuvers. Other types of bipods can also be used besides the tripod.

[0125] In some embodiments, the tripod is equipped with an Arca-Swiss interface 7100, and the shape of the second connection portion 1120 is adapted to the Arca-Swiss interface 7100.

[0126] In this embodiment, the shape of the second connecting part 1120 is set to match the shape of the Arca-Swiss interface 7100, so that the rifle can be quickly mounted on the tripod 7000 of the Arca-Swiss interface 7100, improving the flexibility during shooting.

[0127] Specifically, the tripod 7000 is equipped with a locking plate with an Arca-Swiss interface 7100, and the second connecting part 1120 is configured as an inclined dovetail structure that matches the Arca-Swiss interface 7100. Specifically, the bottom of the second connecting part 1120 is provided with a fourth screw hole 1121 for fixing the second connecting part 1120 to the tripod 7000 by a first bolt.

[0128] It should be noted that the tripod 7000 with Arca-Swiss interface 7100 is usually used in photography and videography as a tripod support and for gimbal turning. Therefore, by setting a second connecting part 1120 at the bottom of the rifle that matches the shape of the Arca-Swiss interface 7100, the rifle can be directly mounted on the tripod 7000 to achieve flexible turning. There is no need to customize the tripod 7000, which can save costs and is convenient to use.

[0129] refer to Figure 1 As shown, in some embodiments, an extended-capacity magazine 8000 is mounted on the bottom of the receiver 1000.

[0130] It should be noted that a conventional sniper rifle magazine can hold 5 bullets, which is a relatively small number of bullets. This application uses an extended magazine 8000, which extends the bottom of the magazine, so it can hold more bullets. The extended magazine 8000 in this embodiment can hold 8 bullets, reducing the number of times the magazine needs to be changed.

[0131] refer to Figure 4 As shown, in some embodiments, a stock 6000 is also provided at the end of the receiver 1000, and the end of the stock 6000 is provided with a height-adjustable base 6400.

[0132] In this embodiment, a height-adjustable buttstock 6400 is provided at the end of the stock 6000. The shooter can adjust the height of the buttstock 6400 against the shoulder according to his own needs to improve stability, comfort and shooting accuracy.

[0133] A vertical groove is provided at the end of the stock 6000, and a slider matching the groove is provided at the front end of the buttstock 6400. The slider is located in the groove and can move up and down along the groove, thereby realizing the height adjustment of the buttstock 6400. A buttstock adjustment knob 6410 with a screw is provided on the side of the groove. The screw of the buttstock adjustment knob 6410 extends into the groove. When the buttstock adjustment knob 6410 is loosened, the buttstock 6400 can move up and down along the groove. When the buttstock adjustment knob 6410 is tightened, its screw fixes the buttstock 6400 in the groove.

[0134] refer to Figure 17 As shown, this application also relates to a rifle, on which the handguard and receiver connection mechanism of the rifle described above are mounted.

[0135] Specifically, in this embodiment, the rifle is a sniper rifle.

[0136] For example, in this embodiment, the sniper rifle model can be CS / LR4, CS / LR4A or any other type of sniper rifle.

[0137] refer to Figure 18As shown, the sniper rifle is also equipped with a 7000 tripod, which allows for flexible turning and aiming.

[0138] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
