Description

Technical Field

[0001] This utility model relates to the field of pneumatic direct drive, and in particular to a high-speed catapult compressed air cannon. Background Technology

[0002] In the traditional field of pneumatic direct drive, pneumatic actuators are limited by factors such as product structure, exhaust method, seals and piston rods, resulting in slow linear motion speed and large structural size, which cannot meet the requirements of high-speed ejection. Utility Model Content

[0003] This application provides a high-speed catapult compressed air gun, which solves the technical problems of slow movement speed and large structural size of pneumatic actuators in the prior art.

[0004] The technical solution adopted in the embodiments of this application is as follows:

[0005] A high-speed catapult-launched compressed air gun includes a barrel, a slide assembly that slides on the barrel, an outer steel belt disposed on the outside of the barrel, an inner steel belt disposed on the inside of the barrel, end caps installed at both ends of the barrel, and a buffer for cushioning the slide assembly; both the outer and inner steel belts pass through the slide assembly; both ends of the outer steel belt are fixedly installed on two sets of end caps by outer steel belt locking plates; both ends of the inner steel belt are fixedly installed on two sets of end caps by inner steel belt locking blocks and locking block pull plates; the buffer is installed on one set of end caps; the barrel has several sets of exhaust holes arranged in a linear array near the end of the buffer.

[0006] A further technical solution is as follows: the slide assembly includes a piston-type slider, a piston head, a wear-resistant ring, a piston seal ring, a buffer head, a rod head, and a fixing block; the bottom end of the piston-type slider slides within the inner cavity of the barrel; piston heads are installed at both ends of the piston-type slider; the wear-resistant ring is fitted onto both sets of piston heads; the piston seal ring with low frictional resistance is fitted onto the ends of both sets of piston heads; the buffer head is installed on one set of piston heads closer to the buffer direction, and the rod head is installed at the end of the buffer head; the fixing block is installed at both ends of the top of the piston-type slider, and each set of fixing blocks slides at both ends of the barrel.

[0007] A further technical solution is that an end cap sealing ring is also provided between the end cap and the barrel.

[0008] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0009] 1. By employing a barrel, slide assembly, outer steel belt, inner steel belt, end caps, and a buffer, and utilizing a double steel belt structure (outer and inner steel belts) and a unique slide assembly design, the internal structure of the barrel is optimized. This design not only improves the structural strength and stability of the entire device but also enhances the safety of the slide assembly during ejection. The effective fixing of the outer and inner steel belts prevents structural damage caused by recoil during slide assembly ejection, significantly extending the equipment's service life. Secondly, the end caps and sealing rings at both ends of the barrel effectively solve the sealing problem, preventing leakage of high-pressure compressed air and ensuring the high efficiency and stability of the slide assembly during ejection. This improvement significantly increases ejection efficiency and reduces energy waste. Furthermore, the low-friction coefficient friction pair between the piston-type slider and the barrel cylinder, along with the application of a self-lubricating wear-resistant ring, greatly reduces the frictional resistance of the slide assembly during sliding. Compared to traditional U-rings, using a hard O-ring as the piston seal not only reduces frictional resistance but also improves sealing performance, resulting in smoother movement of the slide assembly and thus increasing firing speed. Furthermore, this invention effectively solves the problem of residual pressure release after firing by opening an exhaust port near the buffer end of the barrel, preventing a decrease in the slide's ejection speed due to excessive residual pressure and reducing noise after the slide assembly ejects. Most importantly, this invention abandons the traditional pneumatic direct-drive structure, using compressed air as the power source to achieve high-speed linear motion of the slide assembly. This not only simplifies the structure and reduces the size but also significantly increases the ejection speed, giving this invention a significant performance advantage.

[0013] This application provides a high-speed ejection compressed air cannon. Compressed air is rapidly injected through the tail port, instantly filling the rear chamber of the cannon. This compressed air propels a slider forward rapidly, achieving high-speed ejection of the load. This solves the problem of traditional pneumatic direct-drive structures by using compressed air as the power source, enabling high-speed linear motion of the slide assembly. This not only simplifies the structure and reduces the size but also significantly improves the ejection speed.

[0014] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] A high-speed catapult compressed air cannon, such as Figure 1 and Figure 2 As shown, the assembly includes a barrel 1, a slide assembly 2 that slides on the barrel 1, an outer steel strip 3 located on the outside of the barrel 1, an inner steel strip 4 located on the inside of the barrel 1, end caps 5 installed at both ends of the barrel 1, and a buffer 6 for buffering the slide assembly 2. Both the outer steel strip 3 and the inner steel strip 4 pass through the slide assembly 2. The two ends of the outer steel strip 3 are fixedly installed on the two sets of end caps 5 by outer steel strip locking plates 7. The two ends of the inner steel strip 4 are fixedly installed on the two sets of end caps 5 by inner steel strip locking blocks 8 and locking block pull plates 9. The buffer 6 is installed on one set of end caps 5. Several sets of exhaust holes 11 arranged in a linear array are provided near the end of the barrel 1 closest to the buffer 6.

[0017] The slide assembly 2 includes a piston-type slider 21, a piston head 22, a wear-resistant ring 23, a piston seal ring 24, a buffer head 25, a rod head 26, and a fixing block 27. The bottom end of the piston-type slider 21 slides within the inner cavity of the barrel 1. Piston heads 22 are mounted at both ends of the piston-type slider 21. Wear-resistant rings 23 are fitted onto both sets of piston heads 22. Piston seal rings 24 are fitted onto the ends of both sets of piston heads 22. A buffer head 25 is mounted on one set of piston heads 22 closer to the buffer 6, and a rod head 26 is mounted at the end of the buffer head 25. Fixing blocks 27 are mounted at both ends of the top of the piston-type slider 21. Each set of fixing blocks 27 slides at both ends of the barrel 1.

[0018] An end cap sealing ring 51 is also provided between the end cap 5 and the barrel 1.

[0019] The buffer 6 is fixedly mounted on one of the end caps 5. Five sets of exhaust ports 11 arranged in a straight line are provided on both sides of the barrel 1 near the buffer 6. Piston heads 22 are fixedly embedded at both ends of the piston-type slider 21. Piston sealing rings 24 are fitted at the ends of both sets of piston heads 22. A buffer head 25 is fixedly mounted on one set of piston heads 22 near the buffer 6, and a rod head 26 is fixedly mounted at the end of the buffer head 25. Fixing blocks 27 are fixedly mounted on both ends of the top of the piston-type slider 21 by bolts, and each set of fixing blocks 27 slides on both ends of the barrel 1. The piston sealing rings 24 are preferably hard O-rings. By rapidly filling the tail vent of one set of end caps 5 with compressed air, the rear cavity of the slide assembly 2 is instantly filled with compressed air. The compressed air pushes the slide assembly 2 to move rapidly along the barrel 1 towards the other set of end caps 5, thereby achieving high-speed ejection of the load. The piston slider 21 and the cylinder body of the barrel 1 have a friction pair with a low coefficient of friction. At the same time, a self-lubricating wear-resistant ring 23 is used. The original U-ring with high frictional resistance is replaced with a hard O-ring with low frictional resistance, which makes the piston slider 21 slide more smoothly during the sliding process.

[0020] By employing the configuration of a barrel 1, a slide assembly 2, an outer steel belt 3, an inner steel belt 4, end caps 5, and a buffer 6, and through the use of a double steel belt structure (outer and inner steel belts 3 and 4) and a unique slide assembly 2 design, the internal structure of the barrel 1 is optimized. This design not only improves the structural strength and stability of the entire device but also enhances the safety of the slide assembly 2 during ejection. The effective fixing of the outer and inner steel belts 3 and 4 prevents structural damage caused by recoil force during ejection, significantly extending the service life of the equipment. Secondly, the end caps 5 and end cap sealing rings 51 at both ends of the barrel 1 effectively solve the sealing problem, preventing leakage of high-pressure compressed air and ensuring the high efficiency and stability of the slide assembly 2 during ejection. This improvement significantly increases ejection efficiency and reduces energy waste. Furthermore, the low-friction coefficient friction pair between the piston-type slider 21 and the cylinder of the barrel 1, and the application of the self-lubricating wear-resistant ring 23, greatly reduce the frictional resistance of the slide assembly 2 during sliding. Compared to traditional U-rings, using a hard O-ring as the piston seal 24 not only reduces frictional resistance but also improves sealing performance, resulting in smoother movement of the slide assembly 2 and thus increasing firing speed and accuracy. Furthermore, by opening an exhaust port 11 at the end of the barrel 1 near the buffer 6, this invention effectively solves the problem of residual pressure release after firing, preventing a decrease in the slide's ejection speed due to excessive residual pressure, and also reducing noise after the slide assembly 2 is ejected. Most importantly, this invention abandons the traditional pneumatic direct-drive structure, using compressed air as the power source to achieve high-speed linear motion of the slide assembly. This not only simplifies the structure and reduces the size but also significantly increases the ejection speed, giving this invention a significant performance advantage.
