Description

Technical Field

[0001] This invention relates to the field of missile locking mechanism technology, and in particular to a locking mechanism for a missile launching device. Background Technology

[0002] In the military field, the locking mechanism of missile launchers is widely used, mainly responsible for locking and unlocking the missile body.

[0003] Currently, the locking mechanisms of missile launchers can be divided into two types based on their operation: manual and automatic. The former mostly uses a manually controlled mechanical structure for unlocking and locking, while the latter typically uses a hydraulic cylinder as a power source for automatic unlocking and locking. The former has a simple structure, but the unlocking force is not adjustable; the latter can adjust the locking force, but because it includes hydraulic cylinders and other driving devices, its reliability is low, and it occupies a large space, further increasing the weight of the launcher. There is a lack of a locking mechanism that is both simple in structure and can adjust the locking force; therefore, this invention is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a locking mechanism for a missile launching device. This locking mechanism has a simple structure and can adjust the locking force.

[0005] The present invention provides a locking mechanism for a missile launching device, including a support frame, an adjusting screw at one end of the support frame, the adjusting screw being connected to a pull rod, the pull rod being connected to a tension spring, one end of the tension spring being connected to a first clamping part, and a second clamping part being provided on the side of the first clamping part away from the tension spring;

[0006] The first clamping part includes a front stop block, which is rotatably connected to the support frame. A first rotating shaft is rotatably connected to the upper part of the front stop block. The tension spring is connected to the first rotating shaft. A baffle is provided at the bottom of the front stop block.

[0007] The lower part of the second clamping part is provided with a slot, which is arranged opposite to the baffle.

[0008] Furthermore, the second clamping part includes a rear stop block, the rear stop block is provided with the slot, the top of the rear stop block is provided with a vertical rod, the middle of the vertical rod is provided with a vertical through groove, the through groove is provided with a limiting rod, the lower part of the limiting rod is provided with a compression spring, the compression spring is sleeved on the vertical rod, the upper part of the limiting rod is provided with a fixing rod, the two ends of the fixing rod are connected to a shift fork, and the shift fork is rotatably connected to the support frame.

[0009] Furthermore, the shift fork includes a sleeve, on which two grooves are provided opposite each other, and the two ends of the fixing rod are respectively fixed in the grooves; the sleeve is provided with an adjusting shaft, and the two ends of the adjusting shaft are rotatably connected to the support frame.

[0010] Furthermore, the second clamping part also includes a fixing seat, which is connected to the top of the support frame. The fixing seat has a sliding groove in the middle, and the vertical rod is located in the sliding groove.

[0011] Furthermore, a bushing is provided on the outside of the first rotating shaft, and a first groove is provided on the bushing, with one end of the tension spring fitted into the first groove.

[0012] Furthermore, the bushing is provided with a first pin hole, in which a first pin is provided, and the first pin is connected to the first rotating shaft.

[0013] Furthermore, the pull rod is provided with two symmetrical adjustment holes, which are connected to the adjustment screws.

[0014] Furthermore, a second groove is provided between the two adjustment holes, and one end of the tension spring is fitted into the second groove.

[0015] Furthermore, horizontal adjustment grooves are provided through the two opposite side walls of the support frame, and the two ends of the pull rod are respectively located in the adjustment grooves.

[0016] Furthermore, it also includes a fixed shaft. The two opposite side walls of the support frame are respectively provided with fixed shaft mounting holes. The front stop is provided with a fixed shaft limiting groove. The fixed shaft passes through one of the fixed shaft mounting holes in sequence, and the fixed shaft limiting groove is inserted into the other fixed shaft mounting hole. The side wall of the limiting groove is provided with a second pin hole, and a second pin is provided in the second pin hole. The second pin is connected to the fixed shaft.

[0017] In summary, the present invention has the following advantages:

[0018] The technical solution provided by this invention clamps the projectile slider with a baffle of the first clamping part and a slot of the second clamping part, keeping it in a locked state and preventing the projectile from moving forward. When the impact force of the projectile is greater than the locking force, the baffle is pushed open, and the projectile is in an unlocked state. By setting a tension spring connected to the first clamping part, the tension spring cooperates with the pull rod to realize the change of the initial length of the tension spring, thereby adjusting the locking force of the locking mechanism. This solves the problem that mechanical locking mechanisms cannot adjust the locking force, and the structure is simple and easy to use. Attached Figure Description

[0035] Example

[0036] A locking mechanism for a missile launcher, such as Figure 1 As shown, it includes a support frame 1, one end of which is provided with an adjusting screw 11. The adjusting screw 11 is connected to a pull rod 2. The pull rod 2 is connected to a tension spring 3. One end of the tension spring 3 is connected to a first clamping part. A second clamping part is provided on the side of the first clamping part away from the tension spring 3.

[0037] like Figure 2 As shown, the support frame 1 has two symmetrical threaded holes 101 at one end. Adjusting screws 11 are installed in the threaded holes 101, and the adjusting screws 11 pass through the threaded holes 101 to connect with the pull rod 2. Figure 3 As shown, the pull rod 2 has two adjusting holes 201 corresponding to the threaded holes 101, and the adjusting screw 11 is connected to the adjusting holes 201. Two horizontal adjusting grooves 102 are provided through the two opposite side walls of the support frame 1. Both ends of the pull rod 2 are located in the adjusting grooves 102 and can slide horizontally along the adjusting grooves 102. The left and right positions of the pull rod 2 are adjusted by adjusting the adjusting screw 11, thereby adjusting the unlocking force. A second groove 202 is provided on the outer peripheral wall of the pull rod 2 at the middle position of the two adjusting holes 201. A cylindrical tension spring 3 is installed in the second groove 202, and the other end of the tension spring 3 is connected to the first clamping part.

[0038] The first clamping part includes a front stop block 10, which is U-shaped, such as... Figure 4 As shown, a baffle 1004 is fixedly connected to the bottom of the front stop block 10. The baffle 1004 is located below the support frame and contacts the slide block during installation. A first rotating shaft 12 is rotatably connected to the upper part of the front stop block 10. A bushing 4 is provided on the outside of the first rotating shaft 12, such as... Figure 5As shown, the bushing 4 has a first groove 401 in the middle, and the other end of the tension spring 3 is fitted into the first groove 401; the bushing 4 has a first pin hole 402, into which a first pin is inserted, and the first pin is connected to the first rotating shaft 12. The front stop block 10 has a first connecting hole 1001 above the two vertical sidewalls, and the two ends of the first rotating shaft 12 are rotatably connected to the first connecting hole 1001.

[0039] The front stop block 10 is rotatably connected to the support frame 1 via the second rotating shaft 13. The second connecting hole 1002 is provided below the first connecting hole 1001. The support frame 1 is provided with a second rotating shaft mounting hole 104 at a position opposite to the second connecting hole 1002. Both ends of the second rotating shaft 13 are connected to the second connecting hole 1002 and the second rotating shaft mounting hole 104.

[0040] A fixed shaft 9 for a manual locking mechanism is installed between the front stop block 10 and the support frame 1. Fixed shaft mounting holes 103 are opened on the two opposite side walls of the support frame 1. A fixed shaft limiting groove 1003 is passed through the horizontal side wall of the front stop block 10. The fixed shaft 9 passes through one of the fixed shaft mounting holes 103 and the fixed shaft limiting groove 1003 in sequence and is inserted into the other fixed shaft mounting hole 103. A second pin hole 1005 is opened on the side wall of the fixed shaft limiting groove 1003 of the front stop block 10. A second pin is inserted into the second pin hole 1005. A small hole is opened on the fixed shaft 9. A third pin is connected to the small hole on the fixed shaft 9.

[0041] The second clamping part includes a rear stop block 5, a vertical rod 507, a fixing seat 6, and a shift fork 7; as shown Figure 6 As shown, the rear stop 5 has a slot 501 corresponding to the baffle 1004 of the front stop 10. The slot 501 is located below the support frame 1. During installation, the slot 501 contacts the other side of the projectile slider to prevent the projectile from moving backward. A wedge-shaped surface 504 is provided on the side of the rear stop 5 opposite to the slot 501 to facilitate projectile installation. The fixed base 6 has countersunk holes 602 at both ends, such as... Figure 7 As shown, the top of the support frame 1 has a mounting hole 105 for a fixed seat, corresponding to the countersunk hole 602, and the two are fixed together by bolts. A sliding groove 601 is provided in the middle of the fixed seat 6. A vertical rod 507 is fixedly connected to the top of the rear stop 5. The vertical rod 507 is located in the sliding groove 601 and can move up and down along the sliding groove 601. A vertical through groove 502 is opened in the middle of the vertical rod 507. A limit rod 505 is slidably connected in the through groove 502. The two ends of the limit rod 505 are fixedly connected to the side wall of the support frame 1. A compression spring 508 is sleeved on the outer periphery of the vertical rod 507. The compression spring 508 is located below the limit rod 505. Figure 8 As shown; a through hole 503 is provided above the through groove 502, and a fixing rod 506 is fixedly connected in the through hole 503. The length of the fixing rod 506 is greater than the diameter of the slide groove 601, and both ends of the fixing rod 506 are connected to the shift fork 7, as shown. Figure 8 As shown.

[0042] The shift fork 7 is rotatably connected to the support frame 1 via the adjusting shaft 8. For example... Figure 9 As shown, the shift fork 7 includes a sleeve 703, on which two opposing grooves 701 are fixedly connected. The two ends of the fixing rod 506 are fixedly connected to the grooves 701, and the adjusting shaft 8 is inserted into the sleeve 703. Figure 10 As shown, the adjusting shaft 8 has a fourth pin hole 801 in the middle, and a third pin hole 702 is provided between the two grooves 701. The third pin passes through the third pin hole 702 and is inserted into the fourth pin hole 801. The third pin is used to fix the relative position of the adjusting shaft 8 and the shift fork 7. The two opposite side walls of the support frame 1 are provided with adjusting shaft mounting holes 106, and the two ends of the adjusting shaft 8 are rotatably connected in the adjusting shaft mounting holes 106.

[0043] The adjusting shaft 8 has hexagonal screw holes 802 at both ends, allowing the adjusting shaft 8 to be rotated using an Allen wrench. This rotates the shift fork 7, causing the vertical rod 507 and the rear stop 5 to move upwards or downwards, facilitating the disassembly and installation of the missile body slider. The support frame 1 has four support frame mounting holes 108 at its bottom, which are connected to the missile launch device by screws. A missile body slider limiting plate 109 is fixed at the bottom of the support frame 1 at a position corresponding to the missile body slider. The missile body slider limiting plate 109 is located between the front stop 10 and the rear stop 5. A rear stop limiting groove 107 is provided on one side of the missile body slider limiting plate 109, and the top edge of the rear stop 5 contacts the top of the rear stop limiting groove 107.

[0044] The locking structure of the missile launcher provided by this invention is used as follows: The support frame 1 is installed inside the missile launcher through the support frame mounting hole 108, so that the baffle 1004 of the front stop block 10 and the slot 501 of the rear stop block 5 extend outside the missile launcher. The fixing shaft 9 is sequentially passed through one fixing shaft mounting hole 103 and the fixing shaft limiting groove 1003, inserted into the other fixing shaft mounting hole 103, and a second pin is inserted into the second pin hole 1005, so that the second pin engages with the fixing shaft. The fixed shaft 9 is connected, and the side wall of the support frame 1 has a hollowed-out section to facilitate the installation of the second pin. Rotating the adjusting shaft 8 moves the fork 7 upward, causing the vertical rod 507 and the rear stop block 5 to move upward, installing the projectile body 14. The projectile body slider 15 is inserted into the guide rail on the missile launcher, so that the front end of the projectile body slider 15 contacts the baffle 1004 of the front stop block 10. Then, the adjusting shaft 8 is rotated in the opposite direction, causing the rear stop block 5 to move downward, so that the slot 501 locks the rear end of the projectile body slider 15, thus locking the projectile body slider 15 in place. Figure 11As shown; when the impact force of the projectile 14 is greater than the locking force, the front stop 10 rotates forward, pushing open the front stop 10 to unlock. When it is necessary to adjust the locking force, rotate the adjusting screw 11 to adjust the distance between the adjusting screw 11 and the pull rod 2, change the initial length of the tension spring 3, change the tension of the tension spring 3, and adjust the unlocking force.

[0045] The locking mechanism of the missile launching device provided by the present invention uses an adjusting screw and a pull rod to change the initial length of the tension spring, thereby changing the magnitude of the tension and adjusting the locking force. This solves the problem that the existing mechanical locking mechanism cannot adjust the locking force. The structure is simple, the first clamping part and the second clamping part are set to clamp firmly, and the installation and disassembly are convenient and highly practical.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
