Description

Technical Field

[0001] The utility model belongs to the technical field of rocket launching, and in particular relates to a locking device and a launching platform. Background Art

[0002] Rocket launch technology is currently widely used in military, weather modification, and model space sports. The rocket launch platform is one of the most critical components of rocket launch technology. It typically includes a launch track and a latch. The latch's primary function is to temporarily secure the rocket to the launch track. When the rocket generates thrust, it overcomes the locking force of the latch, freeing the launch platform and completing the launch. Previous rocket launch platforms had a one-piece latch structure. During use, the rocket's thrust plastically deformed the latch, allowing the rocket to disengage. This latch structure lacked adjustable locking force, requiring a new latch to be replaced after each launch and reloading the rocket. This increased launch costs and prolonged preparation time for each rocket launch, severely limiting launch performance. Summary of the Invention

[0003] The purpose of the utility model is to provide a lock and a launch platform to solve the problem that the lock needs to be replaced after each launch on the traditional launch platform.

[0004] The utility model is achieved through the following technical solutions:

[0005] Locking device, including:

[0006] A base, wherein the base is provided with a guide rail surface for installing the guide rail;

[0007] A locking member is disposed in the base and allows an upper portion of the locking member to extend beyond the plane of the guide rail in a free state, so that the locking member can limit the movement of the slider on the guide rail;

[0008] When the slider applies a force in the horizontal direction to the locking member and the applied force reaches a set value, the locking member can be elastically deformed and pressed into the base, so that the locking member releases the restriction on the slider.

[0009] In some embodiments, the locking member includes a limiting section with a folding plate structure, one end of the limiting section is fixedly connected to the base, and the other end is a free end, and the limiting section forms a limiting portion at the bending position, and the limiting portion extends out of the plane where the guide rail surface is located.

[0010] In some embodiments, an unlocking component is further included, which is used to apply a force to the free end of the limiting section to elastically deform the limiting section and move the limiting portion into the base to release the restriction on the slider.

[0011] In some embodiments, the unlocking assembly includes a tightening screw, one end of which is connected to the free end of the limiting section, and the other end is threadedly connected to the fixed part of the locking member, so that the tightening screw can apply a force to the free end of the limiting section toward the fixed part of the locking member.

[0012] In some embodiments, the locking member also includes a fixed section, which is fixedly arranged on the base. An elastic adjustment section is arranged between the fixed section and the limiting section. One end of the elastic adjustment section is connected to one end of the fixed section, and the free end of the elastic adjustment section is connected to one end of the limiting section.

[0013] In some embodiments, the locking member is formed by integrally bending an elastic metal plate.

[0014] In some embodiments, an elastic adjustment component is further included, which is used to apply a force to the elastic adjustment section to adjust the force required to enable the limiting portion to move into the base to release the restriction on the slider.

[0015] In some embodiments, the elastic adjustment assembly includes an adjusting screw, one end of which is connected to the base and the other end is threadedly connected to the elastic adjustment section, so that the adjusting screw can apply a force to the elastic adjustment section toward the free end away from the limiting section.

[0016] Launch platform, including:

[0017] A guide frame, wherein the guide frame is provided with a guide surface for installing the guide rail;

[0018] The above-mentioned locker is arranged on the guide frame, and the guide surface of the base and the guide surface of the guide frame are located in the same plane;

[0019] Guide rails are arranged on the guide frame and the lock.

[0020] In some embodiments, a bullet stopper is provided on the guide frame for limiting the movement of the aircraft in a direction away from the locker.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] 1. The utility model improves the locker so that the upper part of the lock piece extends out of the plane of the guide rail surface. When the slider applies a force in the horizontal direction to the lock piece and the applied force does not reach a set value, the lock piece can limit the slider on the guide rail. When the slider applies a force in the horizontal direction to the lock piece and the applied force reaches a set value, the lock piece can be elastically deformed and pressed into the base, so that the lock piece releases the restriction on the slider. After the slider successfully passes through the lock piece, the lock piece can return to its initial state under the action of elasticity, thereby realizing the reuse of the lock piece, which effectively solves the problem that the existing lock piece needs to be replaced after each launch. While reducing costs, it also reduces the time required for launch preparation.

[0023] 2. The locking piece is formed by bending an elastic metal plate as a whole and is fixedly connected to the base through a fixing portion on the locking piece, which facilitates the installation, removal and replacement of the locking piece and reduces the time of the entire operation process.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0031] Example 1

[0032] like Figures 1 to 4 As shown, the latch comprises:

[0033] A base 8, wherein the base 8 is provided with a guide rail surface 4 for mounting the guide rail;

[0034] The locking member 2 is arranged in the base 8 and the upper portion of the locking member 2 can extend out of the plane of the guide rail in a free state, so that the locking member 2 can limit the movement of the slider 5 on the guide rail;

[0035] When the slider 5 applies a force in the horizontal direction to the locking member 2 and the applied force reaches a set value, the locking member 2 can be elastically deformed and pressed into the base 8, so that the locking member 2 releases the restriction on the slider 5.

[0036] The present invention improves the locker so that the upper part of the locking member 2 extends out of the plane of the guide rail surface. When the slider 5 applies a force in the horizontal direction to the locking member 2 and the applied force does not reach the set value, the locking member 2 can limit the slider 5 on the guide rail. When the slider 5 applies a force in the horizontal direction to the locking member 2 and the applied force reaches the set value, the locking member 2 can be elastically deformed and pressed into the base 8, so that the locking member 2 releases the restriction on the slider 5. After the slider 5 successfully passes through the locking member 2, the locking member 2 can return to its initial state under the action of elasticity, thereby realizing the reuse of the locker, which well solves the problem that the existing locker needs to be replaced after each launch. While reducing costs, it also reduces the time required for launch preparation.

[0037] Example 2

[0038] like Figure 2 As shown, the locking member 2 includes a limiting section 24 with a folding plate structure, one end of the limiting section 24 is fixedly connected to the base 8, and the other end is a free end, and the limiting section 24 forms a limiting portion 21 at the bending position, and the limiting portion 21 extends out of the plane where the guide rail surface is located. The limiting section 24 includes a first slope section that rises gradually and a second slope section that descends gradually. The intersection of the first slope section and the second slope section forms the limiting portion 21. The use of the slope section can better cooperate with the slider 5, making the slider 5 move more smoothly.

[0039] Example 3

[0040] like Figure 2 As shown, the locking member 2 also includes an unlocking component, which is used to apply a force to the free end of the limiting section 24 to cause the limiting section 24 to elastically deform, and to move the limiting portion 21 into the base 8 to release the restriction on the slider 5. The free end of the limiting section 24 can be manually adjusted through the unlocking component, making the movement or limitation of the slider 5 more flexible.

[0041] In some embodiments, the unlocking assembly includes a tensioning screw 26, and a sliding groove is provided on the free end of the limiting section 24. The tensioning screw 26 passes through the sliding groove and is threadedly connected to the fixed part of the locking member 2. By rotating the tensioning screw 26, the tensioning screw 26 can apply a force to the free end of the limiting section toward the fixed part of the locking member, so that the limiting section can be elastically deformed toward the inside of the base, thereby facilitating the unlocking and adjustment operation of the locking member.

[0042] In some embodiments, a locking piece 27 is provided on the tightening screw 26, and the locking piece 27 is fixedly connected to the tightening screw 26 to form an integrated structure. When the locking piece 27 is rotated, the tightening screw 26 can be driven to rotate, so that the tightening screw 26 can adjust the limiting section 24 of the locking piece, and the limiting section 24 undergoes elastic deformation.

[0043] Example 4

[0044] like Figure 2 As shown, the locking member 2 also includes a fixed section 23, which is fixedly arranged on the base 8. An elastic adjustment section 22 is provided between the fixed section 23 and the limiting section 24. One end of the elastic adjustment section 22 is connected to one end of the fixed section 23, and the free end of the elastic adjustment section 22 is connected to one end of the limiting section 24. The locking member 2 is formed by integrally bending an elastic metal plate, and is fixedly connected to the base 8 through the fixing portion on the locking member 2, which facilitates the installation, disassembly and replacement of the locking member 2, reducing the time of the entire operation process.

[0045] Example 5

[0046] like Figure 1 and Figure 2 As shown, the locking member 2 further includes an elastic adjustment component for applying a force to the elastic adjustment section 22 to adjust the force required to enable the limiting portion 21 to move into the base 8 to release the restriction on the slider 5 .

[0047] In some embodiments, the elastic adjustment assembly includes an adjusting screw 7, a fixing plate 3 is provided on the base 8, the adjusting screw 7 passes through the fixing plate 3 and is rotatably connected to the fixing plate 3, and the threaded end of the adjusting screw 7 is threadedly connected to the elastic adjustment section 22, so that the adjusting screw 7 can apply a force to the elastic adjustment section 22 in the direction away from the free end of the limiting section 24. By rotating the adjusting screw 7, the pre-tightening force of the locking member 2 can be adjusted, and it can adapt to different rockets or different locking forces, which solves the problem that an existing lock can only be suitable for one rocket locking force. While reducing the cost, it also improves the adaptability of the lock.

[0048] Example 6

[0049] like Figure 3 and Figure 4 As shown, the launch platform includes:

[0050] A guide frame 41 is provided with a guide surface for mounting a guide rail. The guide frame 41 is fixed by a mounting lug 1. The guide frame 41 and the mounting lug 1 are connected by welding.

[0051] The latch in the above embodiment is provided on the guide frame 41 , and the guide rail surface 4 of the base 8 and the guide surface of the guide frame 41 are located in the same plane;

[0052] The guide rail 42 is provided on the guide frame 41 and the lock.

[0053] When the lock is subjected to the force generated by the rocket launch, the lock can undergo elastic deformation and thus release the restriction on the rocket movement. After the rocket launch is completed, the lock can return to its initial state under the action of the elastic part, thereby realizing the reuse of the lock; and the lock is provided with a preload adjustment part for adjusting the elastic preload force of the elastic part, which can adapt to different rockets or different locking forces, and well solves the problem that the existing lock needs to be replaced after each launch. While reducing costs, it also reduces the time required for launch preparation.

[0054] like Figure 3 As shown, a bullet stopper 6 is provided on the guide frame 41 for limiting the movement of the aircraft in the direction away from the lock. The bullet stopper 6 is connected to the guide rail by rotation. When the bullet stopper 6 is rotated to the blocking state, a part of the bullet stopper 6 protrudes from the upper end surface of the guide rail to limit the tail of the rocket; when it is rotated to the yielding state, the bullet stopper 6 is located as a whole below the upper end surface of the guide rail, releasing the limit on the tail of the rocket and realizing the rapid loading and unloading of the rocket.
