Description

Technical Field

[0001] This utility model relates to the field of artillery shell launching technology, and in particular to a projectile stopper. Background Technology

[0002] Due to the unique nature of shipboard decoy systems, which require operation on the deck, the environment inside the launch tube is completely different from that on land. Environmental factors such as sea waves must be taken into account. However, the existing decoy systems mostly use fixed structures for their decoy stopping devices, which cannot be adapted to different decoy weights or complex sea conditions. This causes the decoy to sway constantly inside the gun barrel with the wind and waves, which may lead to the decoy slipping out of the gun barrel, posing a safety hazard. Consequently, the decoy may not be able to effectively complete the mission and delay the opportunity to strike. Utility Model Content

[0003] The purpose of this invention is to provide a projectile stopper that solves the problem that the ship's hull sways due to wind and waves at sea, causing the projectile to sway inside the gun barrel, which in turn leads to the projectile slipping out of the gun barrel cavity and creating a safety hazard.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A spring-loaded stopper includes a stopper box, the stopper box having a through channel, the channel including a pin groove and a buffer groove, a stopper pin being slidably connected in the pin groove by a spline structure, multiple leaf springs being detachably installed in the buffer groove, two sets of mounting ports for installing leaf springs being symmetrically provided on both sides of the buffer groove, leaf spring covers being detachably installed at each mounting port of the stopper box, a stopper cover being fixed at the end of the stopper box away from the pin groove, a locking block being fixed between the leaf spring and the stopper cover, and the end of the stopper pin away from the leaf spring extending to one side of the outer wall of the stopper box and having a guide ramp and a limiting right-angle notch at the end.

[0005] Preferably, the guide ramp is located in the opposite direction of the projectile's launch, and the limiting right-angle notch is located on the other side of the guide ramp. The limiting right-angle notch is used to engage the bottom edge of the projectile and limit the projectile's lateral movement and axial retraction within the gun barrel.

[0006] Preferably, the locking block has an arc-shaped groove on the side opposite to the leaf spring to accommodate the elastic deformation of the leaf spring. The number of leaf springs is adjusted according to the weight of the spring to meet different load requirements.

[0007] Preferably, the side of the stop pin opposite to the leaf spring has a ball-shaped structure.

[0008] Preferably, both the stop cover and the stop box are provided with through threaded holes, and a spacing adjustment bolt is installed in the threaded holes. The end of the spacing adjustment bolt abuts against the side of the locking block away from the leaf spring.

[0009] Preferably, a limiting block is also installed at the connection node between the pin groove and the buffer groove. The limiting block is used to limit the sliding distance of the bobbin pin in the pin groove.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] 1. This utility model uses the combination of a stop pin structure and a leaf spring structure. It uses a right-angle notch and a guide ramp on the outer surface of one side of the stop pin to limit the projectile. The stop pin is limited by different numbers of leaf springs and locking blocks.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 4This embodiment provides a spring-loaded stopper, including a stopper box 1. The stopper box 1 has a through-channel 101, which includes a pin groove 1011 and a buffer groove 1012. A stopper pin 2 is slidably connected to the pin groove 1011 via a spline structure. A limiting block 3 is installed at the connection point between the pin groove 1011 and the buffer groove 1012 to limit the sliding distance of the stopper pin 2 within the pin groove 1011. The side of the stopper pin 2 opposite to the leaf spring 4 has a ball-shaped structure. Multiple leaf springs 4 are detachably installed in the buffer groove 1012. Two sets of mounting ports for installing the leaf springs 4 are symmetrically provided on both sides of the buffer groove 1012. Leaf spring covers 7 are detachably installed at each mounting port of the stopper box 1. A stopper cover 6 is fixed to the end of the buffer groove 1012 away from the pin groove 1011. The leaf springs 4 and... A locking block 5 is also fixed between the stop cover 6 and the stop body cover 6. The locking block 5 has an arc-shaped groove on the side opposite to the leaf spring 4 to accommodate the elastic deformation of the leaf spring 4. The number of leaf springs 4 is adjusted according to the weight of the projectile to meet different load requirements. The end of the stop pin 2 away from the leaf spring 4 extends to the outer wall of the stop body box 1 and has a guide bevel 201 and a limiting right angle notch 202 at the end. The guide bevel 201 is set in the opposite direction of the projectile launch, and the limiting right angle notch 202 is set on the other side of the guide bevel 201. The limiting right angle notch 202 is used to lock the bottom edge of the projectile and limit the left and right movement and axial retraction of the projectile in the barrel. Both the stop cover 6 and the stop body box 1 have through threaded holes 8. A spacing adjustment bolt is installed in the threaded hole 8. The end of the spacing adjustment bolt abuts against the side of the locking block 5 away from the leaf spring 4.

[0019] Working principle: During operation, firstly, based on the shape of the projectile's outer surface at the point of use, select a stopping pin 2 that matches the shape of the projectile's outer surface at the installation location. Then, open the stopping cover 6 and insert the stopping pin 2 into the inner cavity of the channel 101, so that the front end of the stopping pin 2 passes through the pin groove 1011, while the guide ramp 201 and the limiting right-angle notch 202 abut against the outer surface of the projectile. Next, the limiting block 3 is engaged at the connection node between the pin groove 1011 and the buffer groove 1012, using the limiting block 3 to limit the sliding distance of the stopping pin 2 within the pin groove 1011. Then, open the leaf spring cover 7 and install the corresponding number of leaf springs 4 into the inner cavity of the stopping box 1. The number of leaf springs 4 can be determined according to the actual weight of the projectile. The excess leaf spring 4 can be stored above the locking block 5 to accommodate different projectiles. The left side of the installed leaf spring 4 is used to press against the right side of the stop pin 2. Then the locking block 5 is installed on the right side of the leaf spring 4. The locking block 5 is used to press and fix the leaf spring 4 towards the stop pin 2. While fixing the stop pin 2, the special shape of the outer surface of the left side of the stop pin 2 is used to limit the different shapes of projectiles to prevent the projectile from sliding out of the gun barrel due to the swaying of the ship. At the same time, it will not affect the projectile firing. Finally, the stop cover 6 and leaf spring cover 7 are installed and fixed to the stop box 1 using the spacing adjustment bolt. The spacing adjustment bolt on one side of the stop cover 6 makes the locking block 5 close to one side of the leaf spring 4 to fix the leaf spring 4.

[0020] This device achieves its purpose of ensuring safety and reliability while maintaining a simple structure. It can ensure the stability of the missile's attitude in complex sea conditions, ensure safety during mission execution and complete the combat mission. At the same time, it is inexpensive, easy to mass-produce, and has certain practical value.
