Description

Technical Field

[0001] This utility model relates to the field of launching equipment, specifically to a detonator opening and closing mechanism and launching equipment. Background Technology

[0002] The detonator linkage mechanism is a crucial component of the launcher system. It opens and closes the detonator. During transport, the closed detonator forms a sealed space with the launcher, facilitating ammunition storage and transport. During firing, the detonator is opened to allow the exhaust gases generated during firing to escape from the ammunition compartment.

[0003] Existing detonator plates use hydraulic cylinders to control their opening and closing via a lever mechanism, such as... Figure 1 As shown, the system includes a hydraulic cylinder 1, a linkage mechanism 2, a detonator plate 3, and a mounting base 4. This mechanism is installed on the exterior of a welded vehicle body. Due to the large size and complex structure of the vehicle body, it is impossible to machine the mounting base 4 of the linkage mechanism 2. The only way to ensure its motion characteristics is to weld the finished mounting base 4 to the vehicle body. This not only occupies external space but also affects the overall aesthetics of the launching equipment. In addition, due to errors in machining and welding, as well as the difficulty in controlling welding deformation, the center position of the mounting base 4 has a large deviation. This not only results in poor sealing between the detonator plate and the launcher, and poor stability of the linkage mechanism, but also causes the linkage mechanism 2, which connects to the detonator plate 3, to frequently experience bending deformation and breakage of the linkage rod during use.

[0004] Furthermore, due to the poor rigidity of the lever mechanism 2, mechanical deformation may occur during use. Therefore, a latch 5 is provided for easy manual operation. When closed, the latch 5 is inserted to ensure the mechanism's seal when the launcher is closed. During detonation, operator error often results in the launcher being opened without releasing the latch, causing the lever of the lever mechanism 2 to break and damage the equipment. The existing detonator linkage mechanism has significant drawbacks and is no longer suitable for launching equipment. Therefore, there is an urgent need to develop a new detonator linkage opening and closing mechanism that is reliable, stable, and easy to install. Summary of the Invention

[0005] In view of the above-mentioned defects and improvement needs of the prior art, the present invention provides a trigger plate linkage opening and closing mechanism, which precisely controls the automatic opening or closing of the trigger plate by driving the pull arm to slide along the track through the launcher, and at least solves the technical problem of poor stability of the pull rod mechanism in the prior art, which easily leads to bending deformation and breakage of the pull rod.

[0006] In view of the above-mentioned defects and improvement needs of the prior art, this utility model also provides a launching device that uses the detonator linkage opening and closing mechanism provided in the first purpose. Since the linkage opening and closing mechanism provided in this application is installed in the ammunition compartment, it ensures the sealing of the launching device. Moreover, the pull arm is an integrally formed plate-shaped curved arm structure, and the linkage opening and closing mechanism has good rigidity. Furthermore, the automatic opening or closing of the detonator is precisely controlled by the pull arm sliding along the track through the launch frame. It is reliable and stable in operation, thereby effectively avoiding the technical problems of bending and breakage of the pull rod mechanism, improving the operating efficiency of the launching device, and reducing maintenance costs.

[0007] To achieve the above objectives, this utility model provides a detonator linkage opening and closing mechanism, which is located inside the ammunition compartment and is used to open or close the ammunition compartment's exhaust port to guide the gas flow generated during ammunition firing.

[0008] As a further improvement to the above technical solution: The aforementioned linkage opening and closing mechanism further includes a track, a pull arm, an energy storage spring, and a fire guide plate; The detonator is connected to the outlet on the outer surface of the ammunition compartment of the launcher via a rotatable component; The track is mounted on the rear surface inside the ammunition compartment via a base; The pull arm is a curved plate-shaped steel structure with its two ends arranged in opposite directions. One end is connected to the detonator plate, and the other end is provided with a rotatable roller. The roller is slidably connected to the track. The pull arm is connected to the launcher through the energy storage spring. A through guide groove is provided on the pull arm, and a limiting device is provided on the guide groove. The launcher rotates clockwise or counterclockwise, causing the pull arm to roll along the guide rail until part of the pull arm extends or retracts from the outlet, and the fire guide plate opens or closes around the rotatable component in an opening manner. The limiting device installed on the guide groove limits the opening angle of the fire guide plate to a preset fixed angle.

[0009] Furthermore, in the aforementioned linkage opening and closing mechanism, there are two bases, which are symmetrically welded to the rear surface inside the ammunition compartment. The rails are respectively installed on the two bases by bolts, and a gasket is provided between the base and the rail.

[0010] Furthermore, in the aforementioned linkage opening and closing mechanism, the track is integrally formed, comprising a straight segment and an arc segment. The straight segment is vertically arranged, and one end of the arc segment is connected to the straight segment, with the extension of the other end extending towards the outlet.

[0011] Furthermore, in the aforementioned linkage opening and closing mechanism, the number of pull arms is two, symmetrically arranged on the left and right sides of the inner surface of the fire guide plate near the edge and corresponding one-to-one with the track. Reinforcing ribs perpendicular to the pull arms are symmetrically arranged on the inner sides of the two pull arms.

[0012] The aforementioned linkage opening and closing mechanism further includes, in which the pull arm comprises a first connecting part, a second connecting part, and a third connecting part, wherein: The end of the first connecting part is connected to a fork-shaped structure, the fork-shaped structure is provided with a through shaft hole, the roller is rotatably mounted on the shaft hole of the fork-shaped structure through a pin, and the roller is slidably connected to the track; The second connecting part is fixedly connected to the inner surface of the fire guide plate, and the second connecting part and the fork-shaped structure connected to the end of the first connecting part are arranged in opposite directions. The third connecting part is a lug structure located in the middle of the pull arm. A connecting hole is provided on the lug structure. The energy storage spring is connected to the lug structure at one end through a fixed seat, and to the launcher at the other end.

[0013] In the aforementioned linkage opening and closing mechanism, the guide groove is an arc-shaped guide groove located on the pull arm body between the second connecting part and the third connecting part. A limiting device is provided through the guide groove. The guide groove can slide along the limiting device under the drive of the pull arm. The limiting device includes a limiting pin and a limiting bolt. The limiting pin is installed on the inner surface of the launcher and passes through the guide groove to connect with the limiting bolt. The limiting device is used to limit the opening angle of the fire plate to a fixed opening angle, so that when the pull arm drives the fire plate to rotate to a fixed preset opening angle, the end of the guide groove abuts against the limiting pin.

[0014] The aforementioned linkage opening and closing mechanism is further described in that when the launcher rotates clockwise, the launcher drives the pull arm upward through the energy storage spring until the roller disengages from the track. The energy storage spring is in a free state, and the contraction of the energy storage spring can cause part of the pull arm to extend outward from the ammunition compartment outlet, pushing the detonator plate to rotate around the rotatable component to open the detonator plate by means of the opening above the detonator plate. When the launcher rotates counterclockwise, the launcher drives the pull arm downward through the energy storage spring until the roller falls into the track. Under the reaction force of the track, the pull arm continues to move downward, causing the pull arm to retract into the ammunition compartment, pulling the detonator plate to rotate around the rotatable component to achieve the closure of the detonator plate.

[0015] Furthermore, in the aforementioned linkage opening and closing mechanism, the number of rotatable components is two. The detonator is installed at the discharge port of the ammunition compartment through the two rotatable components, so that the detonator and the ammunition compartment body form a hinge-like structure. The rotation axes of the two rotatable components extend horizontally and are coaxially arranged.

[0016] To achieve the above objectives, this application also provides a launching device, including a vehicle body and a launcher, wherein the launcher is equipped with the aforementioned detonator linkage opening and closing mechanism.

[0017] Furthermore, in the aforementioned launching device, the bottom of one end of the launching frame is hinged to the vehicle body via a rotary shaft, and the front side of the launching frame is hinged to a hydraulic cylinder mounted on the vehicle body. The clockwise or counterclockwise rotation of the launching frame is achieved by extending and retracting the hydraulic cylinder.

[0018] Based on the above technical solution, this utility model has at least the following beneficial effects compared with the prior art: This utility model provides a detonator linkage opening and closing mechanism, including a track, pull arms, an energy storage spring, and a detonator. The structure is simple and easy to install and adjust. Since the linkage opening and closing mechanism is installed inside the ammunition compartment, it does not occupy the external space of the launching equipment, resulting in a neat and aesthetically pleasing appearance. In the closed state, the linkage mechanism is completely within a sealed space, ensuring the complete sealing of the launching device and avoiding adverse effects from dust, rain, and snow, thus reducing maintenance requirements. The two pull arms are integrally formed curved plate-shaped steel structural components, with their ends arranged in opposite directions. Reinforcing ribs are added to the relative inner sides of the two pull arms, effectively improving the rigidity of the linkage opening and closing mechanism. It is not controlled by hydraulics or electricity, effectively enhancing its reliability. The automatic opening or closing of the detonator can be precisely controlled by the sliding of the pull arms along the track via the launching frame, allowing the detonator to open or close smoothly and at a uniform speed. The linkage opening and closing mechanism has good stability, and the maximum rotation range of the pull arms is limited by the limiting device installed on the guide groove, thus ensuring that the detonator can only open at a fixed angle. The force for opening or closing the detonator is provided by the oil storage spring. Since the connection between the storage spring, the linkage opening and closing mechanism, and the launcher is a flexible connection, even if the detonator is subjected to external resistance (such as foreign objects outside the launcher that prevent the detonator from opening), it will not cause damage to the linkage opening and closing mechanism. It also effectively avoids the problems of bending deformation and breakage of the pull rod in the prior art, improves the operation efficiency, and reduces the maintenance and repair costs.

[0019] This utility model also provides a launching device, including a vehicle body and a launching frame. The launching frame is equipped with the aforementioned detonator linkage opening and closing mechanism. The bottom of one end of the launching frame is hinged to the vehicle body via a rotary shaft. The front side of the launching frame is hinged to a hydraulic cylinder mounted on the vehicle body. The clockwise or counterclockwise rotation of the launching frame is achieved by the extension and retraction of the hydraulic cylinder. Since the linkage opening and closing mechanism provided in this application is installed inside the ammunition compartment, the sealing of the launching device is ensured, facilitating transportation during military operations. Due to the high rigidity of the linkage opening and closing mechanism, and the flexible connection between the launching frame and the linkage opening and closing mechanism via an energy storage spring, the damage rate of the equipment is reduced, the operating efficiency of the launching device is improved, and the maintenance cost is reduced. Furthermore, the automatic opening or closing of the detonator is precisely controlled by the launching frame driving the pull arm to slide along the track, ensuring reliable operation and good stability.

[0020] In summary, the trigger plate linkage opening and closing mechanism and launching device of this utility model have at least the aforementioned advantages and practical value. No similar products have been publicly disclosed or used in the same category, which is indeed an innovation. It produces a useful and practical effect, has an improved technical effect compared with the existing technology, and is therefore more suitable for practical use. It also has broad industrial value and is suitable for promotion and application.

[0028] This application provides a fire detonator linkage opening and closing mechanism, such as... Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the linkage opening and closing mechanism is installed inside the ammunition compartment 13 of the launcher 12, and includes a rail 6, a pull arm 7, an energy storage spring 8, and a detonator 3. The launcher 12 rotates clockwise or counterclockwise, causing the pull arm 7 to roll along the guide rail 6 until a portion of the pull arm 7 extends or retracts from the outlet 131, and the detonator 3 opens or closes around the rotatable component 9. A limiting device 77 installed on the guide groove 76 limits the opening angle of the detonator 3 to a preset fixed angle. This detonator linkage opening and closing mechanism is used to open or close the outlet 131 of the ammunition compartment 13 to guide the gas flow generated during ammunition firing. The launcher 12, equipped with this detonator linkage opening and closing mechanism, is mounted on the vehicle body 13, together forming another embodiment of the launching device provided in this application.

[0029] The linkage opening and closing mechanism in this embodiment includes a track 6, a pull arm 7, an energy storage spring 8, and a fire guide plate 3.

[0030] In this embodiment, the ammunition compartment 13 of the launcher 12 is a receiving cavity with an outlet 131 on its side wall. The detonator 3 is connected to the outlet 131 on the outer surface of the ammunition compartment of the launcher via a rotatable component 9. The track 6 is mounted on the rear surface inside the ammunition compartment 13 via a base 61. The pull arm 7 is constructed as a curved plate-shaped steel structure with its two ends arranged in opposite directions. One end is connected to the detonator 3, and the other end is provided with a rotatable roller 78. The roller 78 is slidably connected to the track 6. The pull arm 7 is connected to the launcher 12 via the energy storage spring 8. A through guide groove 76 is provided on the pull arm 7, and a limiting device 77 is provided on the guide groove 76.

[0031] The launcher 12 rotates clockwise or counterclockwise, causing the pull arm 7 to roll along the guide rail 6 until part of the pull arm 7 extends or retracts from the outlet 131, and the fire guide plate 3 automatically opens or closes around the rotatable component 9. The limiting device 77 installed on the guide groove 76 limits the opening angle of the fire guide plate 3 to a preset fixed angle.

[0032] The opening and closing principle of the fire guide plate linkage opening and closing mechanism in this application embodiment is explained as follows: 1) Opening principle: In operation, the hydraulic cylinder 1 pushes the launcher 12 to rotate clockwise along the rotary shaft 10. The launcher 12, through the energy storage spring 8, drives the pull arm 7 upward until the roller 78 disengages from the track 6. At this point, the energy storage spring 8 is in a free state. The contraction of the energy storage spring 8 causes a portion of the pull arm 7 to extend outward through the discharge port 131 of the ammunition compartment 13, pushing the detonator 3 to rotate around the rotatable component 9, thus opening the detonator 3 with an opening above it. Because a guide groove is provided on the pull arm 7, the maximum rotation range of the pull arm 7 is limited by the limiting device 77, so that the detonator 3 can only open at a fixed angle.

[0033] 2) Closing principle: When the hydraulic cylinder 1 pushes the launcher 12 to rotate counterclockwise along the rotating shaft 10, the launcher 12 drives the pull arm 7 to move downwards through the energy storage spring 8 until the roller 78 falls into the track 6. Under the reaction of the track 6, the pull arm 7 continues to move downwards, causing the pull arm 7 to retract into the ammunition compartment 13, pulling the detonator 3 to rotate around the rotatable component 9 to achieve the closure of the detonator 3.

[0034] Compared to the existing technology that uses a hydraulic cylinder to control the opening and closing of the detonator via a lever mechanism, the embodiment of this application uses a launcher to drive a linkage opening and closing mechanism to achieve automatic opening or closing of the detonator, and can limit the fixed opening angle of the detonator. Its structure is simple, and it can maintain high stability and reliability throughout the opening or closing process. Moreover, it is installed in the ammunition compartment of the launcher, avoiding the adverse effects of dust, rain and snow on the mechanism, effectively avoiding the bending deformation and breakage of the lever in the prior art, reducing repair and maintenance costs, and improving operation efficiency.

[0035] In the illustrative embodiment of the detonator linkage opening and closing mechanism provided by this utility model, there are two bases 61, which are symmetrically welded to the rear surface of the ammunition compartment 13. The rails 6 are respectively installed on the two bases 61 by bolts 62. A shim 63 is provided between the base 61 and the rail 6. The thickness of the shim 63 can be increased or decreased according to actual needs to adjust the parallelism of the two rails 6, effectively avoiding errors due to processing, welding, etc., so as to ensure that the left and right rails 6 can contact the rollers 78 at the same time, ensuring the synchronous movement of the left and right pull arms 7 of the detonator and the reliable sealing of the detonator 3.

[0036] In the illustrative embodiment of the fire-guide plate linkage opening and closing mechanism provided by this utility model, the track 6 is integrally formed, including a straight segment and an arc segment. The straight segment is vertically arranged, and one end of the arc segment is connected to the straight segment and has a rounded transition. The extension line of the other end of the arc segment extends toward the outlet 131. By setting the arc track 6, when the roller slides into the track 6, a reaction force will be generated, which will stretch the energy storage spring 8 to store energy. The arc track 6 can precisely control the movement trajectory of the roller.

[0037] In the illustrative embodiment of the fire-guiding plate linkage opening and closing mechanism provided by this utility model, there are two pull arms 7, symmetrically arranged on the left and right sides of the inner surface of the fire-guiding plate 3 near the edge, and corresponding one-to-one with the track 6. Reinforcing ribs 79 perpendicular to the pull arms are symmetrically provided on the inner sides of the two pull arms 7, effectively improving the rigidity of the pull arms 7. Figure 6 As shown.

[0038] In the illustrative embodiment of the fire-guiding plate linkage opening and closing mechanism provided by this utility model, such as Figure 4 As shown, the pull arm 7 includes a first connecting part 71, a second connecting part 74, and a third connecting part 75.

[0039] The first connecting part 71 is connected to a fork-shaped structure 72 at its end. The fork-shaped structure 72 has a through shaft hole. The roller 78 is rotatably mounted on the shaft hole of the fork-shaped structure through a pin 73. The end of the pin 73 is provided with a washer and a cotter pin. The roller 78 is slidably connected to the track 6.

[0040] The second connecting part 74 is welded to the inner surface of the fire guide plate, and the second connecting part 74 and the fork-shaped structure 72 connected to the end of the first connecting part 71 are arranged in opposite directions.

[0041] The third connecting part 75 is a lug structure located in the middle of the pull arm 7. A connecting hole is provided on the lug structure. The energy storage spring 8 is connected to the lug structure at one end through the fixing seat 81, and connected to the launcher 12 at the other end. The connection between the energy storage spring 8, the launcher 12, and the pull arm 7 is a flexible connection, so that even if the detonator 3 is subjected to external resistance, the mechanism will not be damaged.

[0042] In an illustrative embodiment of the trigger plate linkage opening and closing mechanism provided by this utility model, the guide groove 76 is an arc-shaped guide groove, disposed on the arm body of the pull arm 7 between the second connecting part 74 and the third connecting part 75. A limiting device 77 is provided through the guide groove 76, and the guide groove 76 can slide along the limiting device 77 under the drive of the pull arm 7. The limiting device 77 includes a limiting pin and a limiting bolt. The limiting pin is installed on the inner surface of the launcher 12 and passes through the guide groove 76 to connect with the limiting bolt. The diameter of the limiting pin is smaller than the width of the guide groove 76, and the diameter of the limiting bolt is larger than the width of the guide groove 76. The limiting device 77 is used to limit the opening angle of the trigger plate 3 to a fixed angle, such as 60 degrees, 45 degrees, 75 degrees, or other angles, so that when the pull arm 7 drives the trigger plate 3 to rotate to the fixed preset opening angle, the end of the guide groove 76 abuts against the limiting pin.

[0043] In the illustrative embodiment of the detonator linkage opening and closing mechanism provided by this utility model, there are two rotatable components 9. The detonator 3 is installed at the discharge port 131 of the ammunition compartment 13 through the two rotatable components 9, so that the detonator 3 and the body of the ammunition compartment 13 form a hinge-like structure. The axis of rotation of the two rotatable components 9 extends horizontally and is coaxially arranged. A sealing ring 31 is provided on the edge of the detonator 3. When the detonator 3 is closed, the detonator 3 is tightly attached to the outer surface of the ammunition compartment 13. The sealing ring 31 is used to seal the gap between the contact surface of the detonator 3 and the ammunition compartment 13.

[0044] Another embodiment of this application provides a launching device, including a vehicle body 11 and a launching frame 12. The launching frame 12 is equipped with the aforementioned detonator linkage opening and closing mechanism. The bottom of one end of the launching frame 12 is hinged to the vehicle body 11 via a rotary shaft 10. The front side of the launching frame 12 is hinged to a hydraulic cylinder 1 mounted on the vehicle body 11. The clockwise or counterclockwise rotation of the launching frame 12 is achieved by the extension and retraction of the hydraulic cylinder.

[0045] Since the linkage opening and closing mechanism provided in the above embodiment uses the launcher to drive the linkage opening and closing mechanism to realize the automatic opening or closing of the detonator plate, and can limit the fixed opening angle of the detonator plate, its structure is simple, easy to install and adjust, and can maintain high stability and reliability throughout the opening or closing process, which facilitates the switching between marching and working states and effectively improves work efficiency.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Various modifications and variations can be made to the present utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0047] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
