Description
Technical Field
[0001] This utility model relates to the field of launching device technology, and in particular to a stable structure inside a launching tube. Background Technology
[0002] As a common launching platform, one of the core functions of a launch tube is to reliably fix and position the projectile inside before launch. This is directly related to the accuracy of the launch and the safety during transportation. To achieve this, existing technologies usually set some fixing structures on the inner wall of the tube.
[0003] However, these conventional fixing structures are often designed to be relatively simple, mostly using rigid protrusions or interference fit between the tube wall and the projectile to achieve fixation. This method has obvious shortcomings. First, its adaptability is very poor. Since the projectile inevitably has dimensional tolerances during the production process, the rigid fixing structure cannot be fine-tuned according to the actual size of the projectile. If the projectile size is too small, it cannot be effectively clamped, causing the projectile to shake inside the tube and affecting the firing accuracy. If the projectile size is too large, it may lead to loading difficulties, or even damage to the surface of the projectile due to rigid compression during the loading process.
[0004] This purely rigid contact method cannot provide any cushioning when subjected to external impacts or vibrations. The impact force will be directly transmitted to the projectile, which may damage the precision components inside the projectile. At the same time, the fixed clamping force is not adjustable, and the fixing strategy cannot be optimized according to different usage scenarios or different types of projectiles. This makes the existing stable structure inside the launch tube inherently defective in terms of reliability and protection.
[0005] Therefore, this utility model proposes a stable structure inside the launch tube to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the problems of insufficient stability of the internal projectile, poor adaptability and easy damage to the projectile in the existing stabilization structure inside the launch tube, the present invention aims to provide a stabilization structure inside the launch tube with improved structure that can effectively solve the above problems.
[0007] This utility model provides a stabilizing structure inside a launch tube, including a tube body, a net bullet filled inside the tube body, and at least one stabilizing adjustment mechanism.
[0008] The cylindrical body has a through hole for installing the stabilizing adjustment mechanism. The stabilizing adjustment mechanism includes a protective shell fixedly connected to the outer wall of the cylindrical body and covering the outside of the through hole, a soft plug slidably connected to the inside of the protective shell, a bolt threaded to the inner wall of the protective shell, a stop plate fixedly connected to one end of the bolt, a rotating block fixedly connected to the other end of the bolt, and a spring disposed between the stop plate and the soft plug.
[0009] Furthermore, one end of the soft plug passes through the through hole and extends into the interior of the cylinder. One end of the spring abuts against the outer wall of the abutment plate, and the other end abuts against the outer wall of the soft plug. With this structural combination, rotating the rotating block can drive the bolt and the abutment plate to move, thereby adjusting the elastic thrust of the spring on the soft plug and achieving precise control of the clamping force of the net spring.
[0010] Preferably, the stabilizing structure inside the launch tube further includes a stabilizing auxiliary mechanism, which includes a rubber protrusion fixedly connected to the outer wall of the net projectile and an annular groove formed on the inner wall of the tube and cooperating with the rubber protrusion. This structure effectively prevents the net projectile from undergoing axial and circumferential displacement through mechanical limiting.
[0011] Preferably, the upper end of the cylinder is provided with a pressure relief hole, which can quickly discharge the compressed air in front of the net projectile when it is launched, so as to avoid abnormal increase in the pressure inside the chamber and thus ensure the stability and safety of the launch process.
[0012] Preferably, the number of the stabilizing adjustment mechanisms is three, and they are evenly distributed along the circumference of the cylinder. This layout allows the clamping force on the net bullet to be applied evenly around its body, ensuring that the net bullet is stably centered and fixed.
[0013] Preferably, the outer wall of the abutment is slidably connected to the inner wall of the protective shell. This sliding fit provides a stable guide for the axial movement of the abutment, ensuring a smooth adjustment process and avoiding jamming or deviation.
[0014] Preferably, the rotating block is located outside the protective shell, allowing operators to easily perform adjustments directly from the outside without disassembling any parts, thus improving ease of use.
[0015] Preferably, the soft plug is made of an elastic material, such as rubber or silicone, which, by utilizing its flexibility, can effectively buffer external impacts and protect the outer wall of the mesh from scratches or pressure damage while providing sufficient friction.
[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of unstable fixation of projectiles, inability to adapt to projectiles of different sizes, and easy damage to the surface of projectiles in the prior art by setting a stable adjustment mechanism that is linked by a rotating block, bolt, backing plate, spring and soft plug. It achieves the technical effect of precise, adjustable and protective elastic stabilization of projectiles inside the tube.
[0017] 2. This utility model solves the problem of axial movement and circumferential rotation of the projectile inside the cylinder by setting rubber protrusions on the outer wall of the projectile and opening an annular groove on the inner wall of the cylinder to match them. It achieves the technical effect of double mechanical restraint of the projectile and further improves the overall stability.
[0018] 3. This utility model solves the problem of excessive chamber pressure caused by the compression of air in front of the projectile during launch, which affects launch stability and safety, by opening a pressure relief hole at the upper end of the cylinder. It achieves the technical effect of balancing the internal and external pressure difference and ensuring a smooth and safe launch process. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please refer to Figures 1 to 4This utility model provides a stable structure inside a launch tube, which aims to solve the problems of insufficient stability of the launch tube for the internal projectile, poor adaptability, and easy damage to the projectile in the prior art.
[0023] like Figure 1 and Figure 2 As shown, the stabilizing structure inside the launch tube includes a tube body 1 and a net projectile 3 filled inside the tube body 1. The tube body 1 serves as the basic platform for launching and carrying, and the net projectile 3 is the projectile to be launched. The stabilizing structure inside the launch tube also includes at least one stabilizing adjustment mechanism 2, which is used to elastically clamp and stabilize the net projectile 3 inside the tube body 1. A through hole is provided on the wall of the tube body 1 for the installation of the stabilizing adjustment mechanism 2. The stabilizing adjustment mechanism 2 includes a protective shell 201, which is fixedly connected to the outer wall of the tube body 1 and covers the outside of the through hole, providing a space and protection for the internal adjustment components. A soft plug 202 is slidably connected inside the protective shell 201. One end of the soft plug 202 passes through the through hole on the wall of the tube body 1 and extends into the interior of the tube body 1 to directly abut against the outer wall of the net projectile 3. The soft plug 202 is made of elastic material to avoid damaging the net projectile 3. A bolt 205 is threadedly connected to the protective shell. On the inner wall of the protective shell 201, one end of the bolt 205 is fixedly connected to the abutment plate 204, and the other end is fixedly connected to the rotating block 206. The rotating block 206 is located outside the protective shell 201, which is convenient for the operator to rotate and adjust. The outer wall of the abutment plate 204 is slidably connected to the inner wall of the protective shell 201 to ensure that it can move smoothly axially under the action of the bolt 205. The spring 203 is set between the abutment plate 204 and the soft plug 202. Specifically, one end of the spring 203 abuts against the outer wall of the abutment plate 204, and the other end abuts against the outer wall of the soft plug 202 to provide a continuous elastic thrust to the soft plug 202. By rotating the rotating block 206, the bolt 205 can be driven to rotate inside the protective shell 201 and generate axial displacement, thereby driving the abutment plate 204 to squeeze or release the spring 203, thereby changing the preload of the spring 203 on the soft plug 202, and finally realizing the precise adjustment of the clamping force of the soft plug 202 on the mesh spring 3.
[0024] The stabilizing auxiliary mechanism 4 includes a rubber protrusion 401 fixedly connected to the outer wall of the net projectile 3, and an annular groove 402 formed on the inner wall of the cylinder 1. The cross-sectional shape of the rubber protrusion 401 and the cross-sectional shape of the annular groove 402 are adapted to each other. After the net projectile 3 is loaded into the cylinder 1, the rubber protrusion 401 is precisely embedded in the interior of the annular groove 402, which can effectively prevent the net projectile 3 from axially shifting or accidentally rotating within the cylinder 1. Thus, it works in conjunction with the stabilizing adjustment mechanism 2 to ensure that the net projectile 3 is in a highly stable ready-to-fire state before launch. In addition, to ensure the safety and stability of the launch process, please refer to... Figure 1At the upper end of the cylinder 1, near its opening, a pressure relief hole 403 is provided. The pressure relief hole 403 penetrates the wall of the cylinder 1 and is used to quickly discharge the compressed air in front of the net projectile 3 when it is launched, balance the environmental pressure inside and outside the cylinder 1, and avoid affecting the launch performance due to the sudden increase in chamber pressure.
[0025] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to apply a uniform and centrally symmetrical clamping force to the net projectile 3, three stabilizing adjustment mechanisms 2 are provided, and these three stabilizing adjustment mechanisms 2 are evenly distributed along the circumference of the cylinder 1, for example, arranged at an angle of 120 degrees to each other, thereby ensuring that the net projectile 3 is stably and centrally positioned within the cylinder 1. Furthermore, inside each stabilizing adjustment mechanism 2, to ensure smooth adjustment and stable force transmission, the outer wall of the abutment plate 204 and the inner wall of the protective shell 201 form a sliding connection. This fit provides axial movement of the abutment plate 204. For precise guidance, preventing tilting or jamming during movement, and to facilitate operator adjustment of clamping force, the rotating block 206 is located outside the protective shell 201, allowing the operator to directly hold and rotate it. Its outer surface can be provided with anti-slip texture to increase friction, making adjustment operation more effortless and reliable. At the same time, to provide a stable clamping while protecting the outer wall of the net bullet 3 from damage, the soft plug 202 is made of an elastic material, such as rubber or silicone. This material has good flexibility and coefficient of friction, and can provide sufficient static friction without scratching the surface of the net bullet 3.
[0026] The working principle of the stabilizing structure inside the launch tube of this utility model is as follows: When loading and securing the net bullet 3, the operator can rotate the rotating block 206. The rotating block 206 drives the bolt 205 to rotate inside the protective shell 201 through a fixed connection. Since the bolt 205 and the protective shell 201 are connected by threads, the bolt 205 will drive the fixed abutment plate 204 to move axially. The movement of the abutment plate 204 will change the compression of the spring 203, thereby adjusting the elastic thrust applied by the spring 203 to the soft plug 202, and finally changing the clamping force of the soft plug 202 on the outer wall of the net bullet 3. By making the same adjustment to the three stabilizing adjustment mechanisms 2, the reliable centering clamping of the net bullet 3 can be achieved to adapt to net bullets 3 of different diameters and provide a stable initial positioning.
[0027] During launch, when the net projectile 3 moves at high speed along the axis of the cylinder 1 under the action of the launch power, its outer wall will squeeze the soft plug 202 outward. Under the elastic action of the spring 203, the soft plug 202 can retract backward into the protective shell 201, making way for the net projectile 3 to pass through. At the same time, the compressed air in front of the net projectile 3 will be quickly discharged through the pressure relief hole 403, avoiding the impact of excessive chamber pressure on launch stability. The cooperation between the rubber protrusion 401 and the annular groove 402 in the stabilizing auxiliary mechanism 4 will always keep the net projectile 3 in axial and circumferential positions before launch, ensuring the correctness of the initial launch attitude.
[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
