One end of the locking part 300 is connected to the card joint, and the locking part 300 is fixed to the bracket 100 through the card joint. The other end of the locking part 300 is connected to the other end of the bracket 100, and the locking part 300 can rotate up and down inside the bracket 100 along the width direction of the bracket 100. The top of the locking part 300 is connected to the external launch tube, which is suitable for locking the external launch tube and the bracket 100.

[0029] In one possible implementation, the locking portion 300 includes a locking bracket 310 and a launch tube spring 320. The locking bracket 310 is a structure with a U-shaped groove and open at both ends. The locking bracket 310 is disposed inside the bracket 100. One end of the locking bracket 310 is connected to the other end of the bracket 100 via a rotating pin. The locking bracket 310 is rotatable up and down along the width of the bracket 100 and is also slidably connected to the external launch tube. A partition 330 is disposed within the locking bracket 310, dividing the locking bracket 310 into a first chamber and a second chamber. A fixing block 360 is disposed on one side of the partition 330. The fixing block 360 is disposed inside the first chamber, and the bottom of the fixing block 360 is a predetermined distance away from the interior of the bottom of the first chamber. The launch tube spring 320 is disposed in the first chamber, with one end of the launch spring 320 connected to the partition 330 and the other end of the launch tube spring 320 connected to the external launch tube. The locking portion 300 also includes a limit block 340 and a limit block spring 350; the limit block 340 has a preset length, and the limit block 340 is rotatably arranged inside the first chamber. A clamping block is provided at one end of the limit block 340, and the clamping block is engaged with the clamping slot; the limit block spring 350 is a sheet structure, and the limit block spring 350 is arranged inside the first chamber. One end of the limit block spring 350 is connected to the inside of the bottom of the first chamber, and is located between the bottom of the fixing block 360 and the inside of the bottom of the locking mounting bracket 310. The other end of the limit spring is arranged at the top of the other end of the limit block 340.

[0030] Specifically, such as Figure 1 As shown, the locking portion 300 includes a locking mounting bracket 310 and a launch tube spring 320; the locking mounting bracket 310 is a structure with a U-shaped groove with both ends of the top open, and this arrangement is to accommodate the launch tube spring 320, the limit block 340 and the limit block spring 350. The locking mounting bracket 310 is arranged inside the bracket 100 to save a certain amount of space. The locking mounting bracket 310 has a preset length, and the length of the locking mounting bracket 310 is less than the length of the bracket 100, so that the locking mounting bracket 310 can be accommodated inside the bracket 100. The locking mounting bracket 310 is arranged inside the bracket 100, and one end of the locking mounting bracket 310 is connected to the other end of the bracket 100 by a rotating pin, and the locking mounting bracket 310 can be rotated along the bracket 100. The external launch tube is connected to the bracket 100 through the locking mounting bracket 310, and the external launch tube can be rotated up and down in the width direction of the bracket 100, and is also slidably connected to the external launch tube. In order to enable the external launch tube to slide relative to the locking mounting bracket 310, one end of the locking mounting bracket 310 is connected to the external launch tube, and the connecting end of the external launch tube and the locking mounting bracket 310 is provided with a connecting block with a certain length. The rotating pin passes through both sides of the bracket 100, both sides of the locking mounting bracket 310 and the connecting block on the external launch tube to realize the connection between the three. That is to say, the external launch tube is connected to the bracket 100 through the locking mounting bracket 310, and the external launch tube can be rotated up and down a certain angle along the width direction of the bracket 100 through the locking mounting bracket 310. When force is applied to the external launch tube, the external launch tube can slide relative to the locking mounting bracket 310. A partition 330 is provided in the locking mounting frame 310, and the partition 330 divides the locking mounting frame 310 into a first chamber and a second chamber. A launch tube spring 320 is provided so that the launch tube spring 320 can return to its original position with the external launch tube after the ammunition is replaced. In order to fix the launch tube spring 320, a partition 330 is provided in the locking mounting frame 310, and the partition 330 divides the locking mounting frame 310 into a first chamber and a second chamber. The launch tube spring 320 is provided in the first chamber, and one end of the launch spring is connected to the partition 330, and the other end of the launch tube spring 320 is connected to the external launch tube.

[0031] In order to enable the external launch tube to slide or be fixed in position when it is stationary, a limit block 340 and a limit block spring 350 are provided. The specific structure of the limit block 340 includes a connector with a certain curvature and a clamping block with a certain length, such as Figure 5 As shown, the connector with a certain curvature is Figure 5 Left side Figure 5The right side starts to tilt upward at a certain angle, forming an arc at the connection between the connector and the locking mounting bracket 310, increasing the area of ​​the connection between the connector and the locking mounting bracket 310, and a through hole is opened at the connection, which is connected to the locking mounting bracket 310 through a bolt body. The card block is fixedly connected to the connector, and one end of the card block has a preset length. The card block is engaged with the bottom of the card slot, so that the top of the card slot of the card shoot 200 is against the launch tube, thereby achieving fixation. In order to enable the limit block 340 to rotate up and down along the width direction of the locking mounting frame 310, a limit block spring 350 is also provided. In order to enable the limit block spring 350 to produce a certain angle, thereby giving the limit block 340 a certain force, a fixed block 360 is provided on one side of the partition 330. The fixed block 360 is provided inside the first chamber, and there is a preset distance between the bottom of the fixed block 360 and the inside of the bottom of the first chamber. One end of the limit block spring 250 is provided between the bottom of the fixed block 360 and the inside of the bottom of the first chamber, and is fixed to the bottom of the first chamber, and the other end of the limit block spring 350 is provided at the top of the other end of the limit block 340, so as to give force to the limit block 340, so that the limit block 340 can produce a certain angle and rotate at a certain angle. Specifically, as Figure 3 and Figure 5 As shown, when the ammunition is not changed, the card block is engaged with the card slot. When changing the ammunition, press the latch 200 to disengage the card block from the latch 200, and the external launch tube slides. When the external launch tube slides to the specified position, the card block enters the card slot of the external launch tube to achieve fixation.

[0032] In one possible implementation, the locking mounting bracket 310 also has a through hole at the connection between the stop block 340 and the stop block spring 350. The bracket 100 has a protrusion 110 disposed therein, and the position of the protrusion 110 matches the position of the through hole in the locking mounting bracket 310.

[0033] Specifically, such as Figure 3 and Figure 4As shown, in order to provide a force to the limit block 340 and the limit block spring 350 , a through hole is also provided on the locking mounting frame 310 at the connection position of the limit block 340 and the limit block spring 350 . The bracket 100 is provided with a protrusion 110 inside, and the setting position of the protrusion 110 matches the position of the through hole on the locking mounting bracket 310. Such a setting can ensure that when the locking mounting bracket 310 does not rotate, the protrusion 110 passes through the through hole on the locking mounting bracket 310 and presses against the limit block 340, causing the limit block 340 to rotate to a certain angle. The limit block 340 presses against the limit block spring 350, and the block at one end of the limit block 340 and the slot of the latch 200 fix the external launch tube. When the locking mounting bracket 310 rotates, the protrusion 110 disengages from the through hole on the locking mounting bracket 310, and the limit block spring 350 applies a force to the limit block 340, so that the limit block 340 is on the horizontal plane. In addition, the movement of the external launch tube causes the block of the limit block 340 to enter the slot of the external launch tube.

[0034] In one possible implementation, a curved protrusion is formed in the middle portion of the stop block 340, and the curvature of the protrusion decreases along the direction of the stop block 340 and the stop block spring 350. The purpose of forming the curved protrusion in the middle portion of the stop block 340 is to better facilitate the formation of a through hole in the protrusion, thereby facilitating the rotational connection with the locking mounting bracket 310 via the bolt body.

[0035] In a possible implementation, a groove is formed at the connection end between the limit block spring 350 and the limit block 340 , and the shape of the groove matches the shape of the connection end between the limit block 340 and the limit block spring 350 .

[0036] In one possible implementation, a connection hole is provided on the first body, extending through the top and bottom of the first body, and a through hole is provided on the second body, extending through both sides of the second body, thereby achieving connection with the bracket 100. The latch 200 is configured in a stepped shape so that one end of the latch 200 can pass through the through hole on the bracket 100 while the other end of the latch 200 can engage with the stop block 340. This configuration also facilitates the through hole provided on the second body, which is rotatably connected to the bracket 100 via the bolt.

[0037] In a possible implementation, a latch spring 210 is further included. The latch spring 210 is vertically connected to the first body, one end of the latch spring 210 is fixedly connected inside the connecting hole, and the other end of the latch spring 210 is set in the external mounting frame.

[0038] Specifically, such as Figure 1 、 Figure 3 and Figure 4As shown, in order to enable the latch 200 to reset after being pressed, a latch spring 210 is further provided. One end of the latch spring 210 is fixedly connected inside the connecting hole, and the other end of the latch spring 210 is provided in the external mounting frame.

[0039] In one possible implementation, the bracket 100 and the locking mounting frame 310 are both rectangular parallelepiped structures having a certain length. In order to match the length of the external launch tube, the bracket 100 and the locking mounting frame 310 are also configured as rectangular parallelepiped structures having a certain length.

[0040] In one possible implementation, a rotating pin 400 is further provided, which passes through a through hole at the connection end between the bracket 100 and the locking mounting bracket 310 , so that the locking mounting bracket 310 can rotate at a certain angle along the rotating pin 400 with the bracket 100 .

[0041] In one possible implementation, a spring guide rod 500 is further provided. The spring guide rod 500 is disposed in the first chamber. One end of the spring guide rod 500 is fixedly connected to the partition 330, and the other end of the spring guide rod 500 is connected to the external launch tube. The launch tube spring 320 is sleeved on the spring guide rod 500.

[0042] When the present application is used, the first step is to press the latch 200 so that the locking portion 300 can rotate along the bracket 100. At this time, the protrusion 110 leaves the through hole of the locking mounting bracket 310, and the limit block spring 350 gives the limit block 340 a force, so that the limit block 340 rotates and remains horizontal. At the same time, the external launch tube slides, and the block of the limit block 340 is stuck in the slot of the external launch tube, which limits the position of the external launch tube. At this time, the bullet is replaced. After the bullet is replaced, the external launch tube is pressed down so that the protrusion 110 enters the through hole of the locking mounting bracket 310, and a pushing force is applied to the limit block 340 and the limit block spring 350, so that the limit block 340 rotates a certain angle. At this time, the block of the limit block 340 is separated from the slot of the external launch tube. The block of the limit block 340 is now connected to the slot of the latch 200, and the slot of the latch 200 presses against the external launch tube, thereby achieving locking.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and concepts of the present invention, should be covered by the scope of protection of the present invention.
