Description

Technical Field

[0001] This invention relates to the field of rifle mounting components, and particularly to a rifle handguard locking mechanism, a rifle handguard, and a rifle. Background Technology

[0002] The handguard is located at the front of the firearm. The shooter holds the handguard to stabilize their position while firing, and it protects the shooter from direct contact with the extremely hot barrel during firing. (Reference) Figure 1 As shown, the handguards of the existing QBZ191 and QBZ192 rifles are connected and locked to the barrel via a front sight base on the barrel. When firing with support, the barrel will be under stress, resulting in accuracy deviation when firing without support. In addition, the handguard is prone to getting hot to the touch when firing after being connected to the barrel. Different locking tightness of the original handguard also interferes with the barrel, causing the accuracy of the scope mounted on the top of the receiver to deviate. The scope needs to be recalibrated every time the handguard is removed for rifle maintenance. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a rifle handguard locking mechanism, a rifle handguard, and a rifle, which enables the handguard to prevent contact with the barrel, thereby maintaining consistent accuracy at the same shooting distance and under different shooting postures.

This invention uses a locking structure to fix the handguard to the rifle, and the connection point between the handguard and the rifle is the slide at the front of the receiver. This prevents the handguard from contacting the barrel, ensuring consistent accuracy across different firing positions and improving the rifle's application scenarios and meeting combat requirements. Because the handguard does not contact the barrel, it solves the problem of the handguard becoming hot and difficult to hold during continuous firing. Furthermore, different locking tightness of the handguard does not interfere with the barrel, preventing interference with scope accuracy during handguard maintenance.

[0015] According to some embodiments of the present invention, the top of the handguard is provided with a guide rail, and the side of the handguard is provided with one or more accessory mounting ports.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0037] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0038] Reference Figure 2 As shown, a rifle handguard locking mechanism includes: a retaining ring 100, a limiting part 200, a locking part 300, and a locking part 400. The retaining ring 100 is sleeved on the rifle sleeve 600. The limiting part 200 is fixed to the rear end of the retaining ring 100, and the retaining ring 100 is fixed to the sleeve 600 by the limiting part 200. The locking part 300 is fixed to the retaining ring 100, and the retaining ring 100 is locked to the rear end of the handguard 500 by the locking part 300. The locking part 400 fixes the locking part 300 to the handguard 500.

[0039] This invention provides an embodiment where a retaining ring 100 is fitted onto the rifle's sleeve 600. The retaining ring 100 is fixed to the sleeve 600 by a limiting part 200. When the handguard 500 is installed, it engages with the retaining ring 100 via a locking part 300, and is then fixedly connected to the handguard 500 by a locking part 400. This makes the handguard 500, retaining ring 100, and sleeve 600 a fixed whole. This invention uses a locking structure to fix the handguard 500 to the rifle, and the connection point between the handguard 500 and the rifle is the sleeve 600 at the front of the receiver. This prevents the handguard 500 from contacting the barrel, thus maintaining consistent accuracy under different firing positions and improving the application scenarios and combat requirements of the firearm. Because the handguard 500 does not contact the barrel, it solves the problem of the handguard 500 getting hot and difficult to hold during continuous rifle firing. Furthermore, the different locking tightness of the handguard 500 does not interfere with the barrel, thus avoiding interference with the accuracy of the scope when maintaining the handguard 500.

[0040] For details, please refer to Figure 2 and Figure 4 As shown, in this embodiment of the invention, the retaining ring portion 100 includes two semi-circular first retaining rings 110 and second retaining rings 120. The tops of the first retaining rings 110 and second retaining rings 120 are integrally formed fixed structures, and the bottoms of the first retaining rings 110 and second retaining rings 120 abut against each other to form an elastic, openable structure. When the retaining ring portion 100 is installed onto the sleeve 600, the bottoms of the first retaining rings 110 and second retaining rings 120 can be pried open to increase the inner diameter of the retaining ring portion 100, facilitating installation. Of course, the retaining ring portion 100 can also be configured as an integral annular structure that is directly fitted onto the sleeve 600.

[0041] refer to Figure 2 and Figure 3 As shown, the outer wall of the retaining ring 100 is provided with anti-slip texture 101 to improve stability during installation. Of course, anti-slip texture 101 can also be provided on both the inner and outer walls of the retaining ring 100. Providing anti-slip texture 101 on the inner wall can increase the friction between the retaining ring 100 and the sleeve 600, thereby increasing stability.

[0042] refer to Figures 2-4 As shown, in this embodiment, the limiting part 200 includes a first retaining groove 210 located at the top of the rear end of the retaining ring part 100 and an annular protrusion 220 located in the upper half of the rear end of the retaining ring part 100.

[0043] Specifically, the first slot 210 is used to engage with the limiting protrusion on the top of the sleeve 600, see reference. Figures 5a-5b As shown, the top of the sleeve 600 has a rectangular limiting protrusion 601, which is located on the central axis of the gun body, extends from the front end of the receiver and engages with the sleeve 600. The rear end of the sleeve 600 is surrounded by a retaining groove. During gun assembly, the sleeve 600 is screwed onto the front end of the gun body, so there is a possibility of rotation. The lower half of the limiting protrusion 601 engages with the retaining groove 602 at the rear end of the sleeve 600. Its purpose is to limit the sleeve 600 and prevent it from rotating. The upper half of the limiting protrusion 601 is completely exposed. Therefore, this application utilizes the existing limiting protrusion 601 at the top of the sleeve 600 to engage the first retaining groove 210 with the upper half of the limiting protrusion at the top of the sleeve 600, which can play a limiting role in the horizontal and vertical directions, so that the retaining ring 100 will not move in the horizontal and vertical directions.

[0044] Specifically, the annular protrusion 220 is used to fit into the gap between the sleeve 600 and the receiver, see reference. Figure 5a As shown, there is a gap between the sleeve 600 and the front end of the receiver. Therefore, this application utilizes this gap to insert a semi-circular annular protrusion 220 into the gap between the sleeve 600 and the receiver. The size of the annular protrusion 220 matches the size of the gap, effectively limiting the forward and backward movement of the locking part 300. This invention cleverly utilizes the limiting protrusion 601 on the sleeve 600 and the gap between the sleeve 600 and the receiver to fix the locking ring 100. The limiting protrusion 601 and the gap are original structural features of the rifle. This application utilizes these original structural features to firmly fix the locking structure to the sleeve 600, preventing displacement and shaking in any direction. It requires no additional fasteners, does not increase the rifle's size, does not alter the rifle's external structure or shape, and does not affect the shooting or gripping posture.

[0045] It should be noted that, in this embodiment, the elastic structure at the bottom of the retaining ring 100 can be used to easily insert the annular protrusion 220 into the gap between the sleeve 600 and the receiver. During installation, the bottoms of the first retaining ring 110 and the second retaining ring 120 are first pried open to slightly enlarge the inner diameter of the retaining ring 100. Then, the retaining ring 100 is moved backward and the annular protrusion 220 is inserted into the gap between the sleeve 600 and the receiver. Finally, the bottoms of the first retaining ring 110 and the second retaining ring 120 are closed. In this way, the annular protrusion 220 can be firmly locked in the gap, preventing the retaining part 300 from moving back and forth.

[0046] refer to Figure 2 , Figure 3 , Figure 6a and Figure 6b As shown, in this embodiment of the invention, the snap-fit ​​portion 300 includes a first snap-fit ​​block 310 located at the top front end of the snap-fit ​​portion 100 and a second snap-fit ​​block 320 located at the bottom of the snap-fit ​​portion 100. Both the first snap-fit ​​block 310 and the second snap-fit ​​block 320 extend forward to snap into the second snap-fit ​​groove 501 corresponding to the rear end of the handguard 500.

[0047] Specifically, the first locking block 310 is elongated and located at the top of the locking ring 100 and extends forward. The upper and lower ends of the inner wall of the rear end of the guard 500 are respectively provided with a second locking groove 501. The thickness of the front end of the first locking block 310 gradually decreases from front to back, making it easy to insert into the second locking groove 501 above the rear end of the guard 500. The second locking block 320 includes two L-shaped inserts, which are located at the bottom of the first locking ring 110 and the second locking ring 120 respectively. When the bottoms of the first locking ring 110 and the second locking ring 120 are closed, the second locking block 320 is inverted T-shaped and is inserted into the second locking groove 501 below the rear end of the guard 500 during installation. When the handguard 500 is installed, it moves along the barrel from front to back until it comes into contact with the gun body. When it moves to the retaining ring 100, the handguard 500 aligns the second retaining groove 501 at the rear end with the first retaining block 310 and the second retaining block 320 respectively and inserts it. Through the engagement of the first retaining block 310, the second retaining block 320 and the second retaining groove 501, the handguard 500 can be fixed on the retaining ring 100 and cannot move in either the horizontal or vertical direction.

[0048] After the rear end of the handguard 500 is fixed to the retaining ring 100 via the snap-fit ​​part 300, the handguard can still move back and forth. In this embodiment, the locking part 400 uses a tenon and mortise structure to limit the forward and backward movement of the handguard 500. (Refer to...) Figure 5a As shown, in this embodiment of the invention, the locking part 400 includes a locking block and a bolt, as referenced. Figure 3As shown, a groove 301 corresponding to the locking block is provided on the side of the L-shaped insert plate at the bottom of the first retaining ring 110. A locking hole corresponding to the locking block is provided on the bottom side of the rear end of the handguard 500. The locking block is inserted into the groove 301 through the locking hole on the handguard 500 to fix the locking part 300 to the handguard 500, thereby limiting the front and rear direction of the handguard 500. Two screw holes are provided on both the locking block and the groove 301. The locking block is then fixed in the locking hole and the groove 301 with bolts, so that the handguard 500, the locking mechanism and the gun body become a fixed whole and will not shake during use.

[0049] In this embodiment, four screw holes are provided on the second locking block 320. Two screw holes correspond to the locking block and the bolt, and the other two screw holes are reserved for independent countersunk limit bolts. When the locking ring 100 is fitted onto the sleeve 600 and the annular protrusion 220 and the locking slot 602 are inserted into place, the two L-shaped insert plates are locked first by the two countersunk limit bolts to prevent them from opening and affecting the subsequent installation of the guard 500. At the same time, it can also make the locking ring 100 better fixed on the sleeve 600, ensuring that the locking structure and the sleeve 600 are installed tightly and without gaps or shaking.

[0050] refer to Figures 6a-6b As shown, the present invention also designs a rifle handguard, including a handguard 500 and a locking mechanism. The locking mechanism is the rifle handguard locking mechanism of the above embodiment. The rear end of the handguard 500 is provided with a second slot 501 that cooperates with the locking part 300.

[0051] This invention can be applied to the plastic handguards of conventional rifles, and can also be adapted to other modified handguards. The plastic handguards of conventional rifles only have the functions of protection and grip, and cannot be equipped with other tactical accessories. This application provides a guide rail 510 on the top of the handguard 500, and multiple accessory mounting ports 520 on the side of the handguard 500.

[0052] Specifically, in this embodiment, the guide rail 510 is a Picatinny rail, and the accessory mounting port 520 is an M-LOK interface. In addition to the side, multiple accessory mounting ports 520 can be provided on the bottom to mount more tactical accessories. To reduce weight, multiple hollow weight-reducing holes are also provided on the side. Of course, in addition to the Picatinny rail and M-LOK interface, other models of rails and accessory mounting ports can be selected according to actual needs.

[0053] refer to Figures 7a-7b As shown, the present invention also relates to a rifle, including a rifle body 700, a handguard 500, and a locking mechanism. The handguard 500 is mounted on the rifle body 700 via the locking mechanism, which is the handguard locking mechanism described in the above embodiment. In this embodiment, the rifle body 700 is a QBZ191 rifle or a QBZ192 rifle.

[0054] In summary, this invention proposes a rifle handguard locking mechanism, a rifle handguard, and a rifle, which prevents the handguard from contacting the barrel, thus maintaining consistent accuracy at the same firing distance and under different firing postures. Because the handguard 500 does not contact the barrel, it solves the problem of the handguard 500 becoming hot and difficult to hold during continuous firing, and also avoids interference with the accuracy of the scope during handguard 500 maintenance. Installing heavy objects such as laser designators, tactical gun lights, grips, and bipods on the handguard 500 will not affect accuracy. The new mounting structure allows the handguard 500 to be extended to the gas system without being fixed to the front sight base, thus improving the grip and not affecting the adjustment and maintenance of the gas system.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention 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 the present invention.
