[0001] The utility model relates to the technical field of launch tubes, and in particular, to a quick pin-removing mechanism for a portable launch tube. Background Art

[0002] A launch tube is a special cylindrical device for holding and launching missiles. It mainly consists of a framework, a cylinder body, a firing control mechanism, and a docking mechanism, and has functions such as supporting, sealing, storing, and launching missiles. Some can also impart an initial rotational speed to the missile and serve as a director for missile launch. When using the launch tube, a pin-removing mechanism is required to control the launch of the missile.

[0003] However, the existing pin-removing mechanisms for portable launch tubes are usually divided into two types: mechanical pin-removing and electronic pin-removing. The traditional mechanical pin-removing structure is complex, involves many parts, and has high requirements for assembly accuracy; electronic pin-removing requires the use of electric detonators, which are costly, and electric detonators belong to pyrotechnic devices and are controlled devices, with low operability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a quick pin-removing mechanism for a portable launch tube to solve the above problems.

[0005] To achieve the above purpose, an embodiment of the utility model provides a quick pin-removing mechanism for a portable launch tube, including: a launch tube cylinder body, an assembly housing installed on the launch tube cylinder body, a grip fixed to the bottom of the assembly housing, an ignition button installed on the grip, a safety cover provided on the assembly housing, a connecting member installed in the safety cover, a bullet-blocking pin member provided on the connecting member, and a bullet-blocking pin channel opened in the launch tube cylinder body and the assembly housing;

[0027] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.

[0028] Please refer to Figure 1 , Figure 1 which shows a perspective view of the present utility model; please refer to Figure 2 , Figure 2 which shows a perspective view of the present utility model in another state; please refer to Figure 3 , Figure 3 which shows a partial disassembly of the present utility model Figure 1 ; please refer to Figure 4 , Figure 4 which shows a partial disassembly of the present utility model Figure 2 ; please refer to Figure 5 , Figure 5 which shows a partial sectional view of the present utility model; please refer to Figure 6 , Figure 6 which shows the present utility model Figure 3 An enlarged view of part A of; as Figures 1 - 6 shown, a portable launch tube quick pin-removing mechanism includes: a launch tube body 1, an assembly housing 2 installed on the launch tube body 1, a grip 3 fixed to the bottom of the assembly housing 2, an ignition button 4 installed on the grip 3, a safety cover 5 provided on the assembly housing 2, a connecting piece 6 installed in the safety cover 5, a bullet blocking pin part 7 provided on the connecting piece 6, and a bullet blocking pin channel 8 opened in the launch tube body 1 and the assembly housing 2;

[0029] A first pin 9 is fixedly connected to the assembly housing 2, and the safety cover 5 is rotatably connected to the assembly housing 2 through the first pin 9;

[0030] A second pin 10 is fixedly connected to the connecting member 6. The anti-bounce pin is rotatably connected to the connecting member 6 through the second pin 10. When the launch tube body 1 is stored or carried normally, the safety cover 5 is rotated with the first pin shaft as the center to close it. Since the anti-bounce pin member 7 can rotate in the safety cover 5 with the second pin shaft as the center, at this time, the head of the anti-bounce pin member 7 can move along the anti-bounce pin channel 8 of the assembly housing 2, driving the anti-bounce pin member 7 to move into the launch tube body 1 along the anti-bounce pin channel 8 in the assembly housing 2 until it is inserted into the launch tube body 1 to lock the missile in the launch tube body 1. At the same time, two sealing rings on the anti-bounce pin are pressed in the anti-bounce pin channel 8 to ensure the airtightness of the tube body and the housing. At the same time, the ignition button 4 on the grip 3 will be covered by the safety cover 5 at this time, and the user's finger cannot touch it and cannot press it to launch, thus realizing the double locking of the missile and the ignition button 4. During combat, the safety cover 5 is pulled downwards, and the anti-bounce pin moves downwards with the safety cover 5 and exits from the anti-bounce pin channel 8 in the assembly housing 2. The missile is unlocked, and at the same time, the ignition button 4 is exposed and can be pressed to complete the launch. Through the cooperation of the limit bump 13 and the two limit circular grooves 12, the opening degree of the safety cover 5 can be restricted to ensure that the head of the anti-bounce pin is still in the housing anti-bounce pin channel 8 when the safety cover 5 is in the maximum open position. If the launch command is cancelled, the safety cover 5 can be reinstalled. The rounded corner of the head of the anti-bounce pin member 7 contacts the conical inner wall of the anti-bounce pin channel 8 in the assembly housing 2 and can be inserted back into the tube body along the channel, realizing reversible operation. The anti-pin withdrawal mechanism of this launch tube is ingeniously designed, with few parts used, easy production and assembly, greatly reducing costs. At the same time, the operation is simple and can achieve foolproof operation, which is beneficial to the low-cost mass production of portable launch tubes.

[0031] Optionally, assembly grooves 11 are formed on both sides of the assembly housing 2, and a number of limit circular grooves 12 are symmetrically formed on the assembly housing 2. The number of limit circular grooves 12 are respectively arranged in the two assembly grooves 11, and two limit bumps 13 adapted to the number of limit circular grooves 12 are symmetrically and fixedly connected to the inner wall of the safety cover 5.

[0032] The safety cover 5 is in interference fit with the two assembly grooves 11. When the safety cover 5 rotates on the assembly housing 2 with the first pin 9 as the center, one of the limit bumps 13 in the safety cover 5 will alternately snap into the two limit circular grooves 12 in one of the assembly grooves 11, thereby completing the opening and closing of the safety cover 5 and restricting the opening degree of the safety cover 5, so that the head of the anti-bounce pin member 7 is still in the anti-bounce pin channel 8 of the assembly housing 2 when the safety cover 5 is in the maximum open position, and thus the anti-bounce pin member 7 can be smoothly inserted back when the safety cover 5 is closed. Through the two limit grooves provided, when the safety cover 5 is in the closed state, the outer wall of the safety cover 5 can be on the same horizontal plane as the outer wall of the assembly housing 2. At the same time, due to the interference fit between the safety cover 5 and the two assembly grooves 11, the stability of the safety cover 5 after closing can be ensured.

[0033] Optionally, the head of the bullet-blocking pin 7 is rounded, and a block 14 is fixedly connected to the lower end of the bullet-blocking pin 7;

[0034] The block 14 is frustum-shaped, and the lower end of the bullet-blocking pin channel 8 is conical. When the bullet-blocking pin 7 moves in the bullet-blocking pin channel 8, the rounded head of the bullet-blocking pin 7 facilitates movement in the conical bullet-blocking pin channel 8. Furthermore, the head of the bullet-blocking pin 7 can move along the bullet-blocking pin channel 8 of the assembly housing 2, enabling the bullet-blocking pin 7 to exit or insert in an arc direction, so as to realize the withdrawal or insertion of the bullet-blocking pin 7 as the safety cover 5 rotates; and the frustum-shaped block 14 is adapted to the bullet-blocking pin channel 8. After the bullet-blocking pin 7 is inserted into the bullet-blocking pin channel 8, the block 14 abuts against the inner wall of the bullet-blocking pin channel 8, effectively improving the stability of the bullet-blocking pin 7 in the bullet-blocking pin channel 8.

[0035] Optionally, two limiting rings 15 are fixedly sleeved on the outer wall of the bullet-blocking pin 7. A first sealing ring 16 and a second sealing ring 17 are movably sleeved outside the bullet-blocking pin 7. The first sealing ring 16 is arranged between the two limiting rings 15, and the second sealing ring 17 is located between the block 14 and one of the limiting rings 15. By the cooperation of the first sealing ring 16 and the second sealing ring 17 provided, when the bullet-blocking pin 7 is placed in the bullet-blocking pin channel 8, the two sealing rings are compressed in the bullet-blocking pin channel 8, ensuring the airtightness of the launcher barrel 1 and the assembly housing 2.

[0036] Optionally, control grooves 18 are symmetrically formed on the outer wall of the safety cover 5. When a user needs to control the opening and closing of the safety cover 5, the user can place the index finger and the thumb in the two control grooves 18 respectively, and then rotate the safety cover 5. The provided control grooves 18 can ensure the stability of the contact between the fingers and the safety cover 5.

[0037] Optionally, a plurality of fixed clamps 19 are sleeved on the launcher barrel 1. Both ends of the plurality of fixed clamps 19 are fixedly connected to the assembly housing 2. By the plurality of fixed clamps 19 provided, the assembly housing 2 and the launcher barrel 1 can be strengthened at multiple points, ensuring the stability of the assembly housing 2 installed on the launcher barrel 1.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
