Description

Technical Field

[0001] This invention belongs to the field of capture device technology, specifically relating to a safe and environmentally friendly handheld capture device. Background Technology

[0002] Traditional military training typically employs several methods for practicing tactical subjects such as close-range control, target capture, and counter-terrorism operations: first, instructors and trainees engage in live-action simulations using props like rubber knives and training handcuffs; second, static or simple mechanical targets are used for practice; and third, comprehensive exercises are conducted in complex environments. These existing training methods have significant limitations: First, live-action simulations demand high levels of physical fitness, skill, and experience from participants and carry a high risk of accidental injury, especially when simulating high-speed, sudden control maneuvers, making absolute safety difficult to guarantee. Second, static or simple mechanical targets lack the dynamic reactions and suddenness of real combat, resulting in insufficient realism and immersion, hindering effective training of trainees' instantaneous reactions and tactical execution capabilities in unexpected situations. Finally, organizing large-scale, comprehensive, real-world exercises is costly, complex, and makes it difficult to repeat and quantify individual tactical maneuvers.

[0003] Existing technologies include some launching or capturing devices for training, such as paintball launchers and laser simulators. However, paintball devices have a high impact force, and even with protective gear, bruises can still occur at very close range. Furthermore, the stains are difficult to clean, making them unsuitable for indoor use or in environments with high cleanliness requirements. While laser simulators are safe, they lack the realistic feedback of physical contact and control, making it impossible to train for crucial aspects requiring physical contact, such as capture and restraint. Summary of the Invention

[0004] The purpose of this invention is to provide a portable training device that can simulate the capture and control process of real entities under extremely high security conditions, so as to fill the gap between dynamic confrontation training and absolute safety requirements.

[0005] The specific technical solution adopted by this invention is as follows: A safe and environmentally friendly handheld trap includes a cylindrical body. A gas generator is fitted inside the middle of the inner wall of the cylindrical body. The gas generator is filled with inert gas. A tray and a trap net cover are arranged sequentially above the gas generator. A trap net is accommodated between the tray and the trap net cover. The tray, trap net, and trap net cover are slidably fitted inside the cylindrical body. An upper cover is threaded to the upper end of the cylindrical body. An air jet hole is opened in the middle of the upper end face of the gas generator. A rupture disc is installed inside the air jet hole. The gas generator is equipped with a heating component that generates heat when excited. The heat generated by the heating component causes the inert gas inside the gas generator to expand, thereby breaking through the rupture disc. The ejected gas drives the tray, the capture net, and the capture net cover to pop out of the cylinder.

[0006] Furthermore, the heating element is an electric heating plate, which is simultaneously connected to the upper end of two terminals and the bottom end of the two terminals are respectively fixedly connected to one end of two relay plates. The two relay plates extend to the outside of the cylinder, and the other end of the two relay plates is respectively fixedly connected to one end of two contact plates. A buffer spring is provided below the insulating cylinder, and the two ends of the buffer spring are respectively fixedly connected to the bottom surface of the insulating cylinder and the bottom surface inside the cylinder. The insulating cylinder is sleeved inside the cylinder.

[0007] Furthermore, the other end of the upper contact plate is electrically connected to one end of the battery, and the battery is simultaneously fixedly connected to one end of both support plates.

[0008] Furthermore, the other end of each of the two support plates is fixedly connected to the inner wall of the battery casing, and the battery casing is overlapped on the outer surface of the cylinder.

[0009] Furthermore, four threaded hole plates are fixedly provided on the outer surface of the battery casing, and the four threaded hole plates are respectively threaded to one end of four bolts.

[0010] Furthermore, the other end of each of the four bolts is threadedly connected to one of the four threaded hole seats, and all four threaded hole seats are fixedly mounted on the outer surface of the cylinder.

[0011] Furthermore, a connecting block is provided between the lower contact plate and the other end of the battery. The end of the connecting block is fixedly connected to one end of the power button. The power button is sleeved in the sleeve hole opened in the battery shell. A support spring is sleeved on the outside of the power button. The two ends of the support spring are fixedly connected to the end of the power button and the outer surface of the battery shell, respectively.

[0012] Furthermore, the heating component is a friction-generating component, including a heating cylinder fixed inside the gas generator and a friction plate that can move relative to the heating cylinder to generate frictional heat.

[0013] Furthermore, the friction plate is connected to a pull ring on the outside of the cylinder by a pull rope. The pull rope passes through a through hole at the bottom of the gas generator. A lower cover is provided below the pull ring, and the lower cover is threaded to the bottom of the cylinder.

[0014] Furthermore, a buffer spring is directly provided below the gas generator, and the two ends of the buffer spring are fixedly connected to the bottom surface of the gas generator and the bottom surface inside the cylinder, respectively.

[0015] The technical effects achieved by this invention are as follows: This invention uses inert gas as the working fluid, which is non-toxic and harmless. It is not a high-pressure container, so there are no special risks in storage and transportation. Compared with spring devices, there is no metal fatigue problem, and its performance is stable during long-term storage. Compared with pre-filled gas tanks, there is no need to replace consumables, making it more economical and environmentally friendly. The core actuator is a soft capture net, which will not cause common training injuries such as impact injuries or cuts when in contact with the human body. The excitation pressure of the gas generator and the popping speed of the capture net can be precisely engineered and calibrated to ensure that its power is sufficient to simulate the suddenness of actual combat, while being strictly controlled within an energy range that is absolutely safe for the human body, fundamentally eliminating the risk of accidental serious injury during training.

[0016] This device overcomes the rigidity of static targets and can simulate the instantaneous dynamics of a target suddenly moving, escaping, or resisting. Operators need to quickly aim, judge, and trigger the capture net, just like in a real scenario. The rapid popping and unfolding of the capture net can realistically simulate the actual combat process of capturing and controlling the net, providing trainees with strong visual and result feedback, greatly enhancing the immersion of training and the realism of the confrontation.

[0017] This invention provides at least two excitation methods: the electrically excited type (Example 1) is easy to operate and can achieve concealed, long-distance, or linkage triggering with other sensors, making it suitable for fixed-point deployment; the pull-out type (Example 2) has a simple structure, requires no battery, and can be used reliably in any environment, making it suitable for portable and emergency use. Both methods share the core gas generating module, resulting in a high degree of product serialization. Attached Figure Description

[0020] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0021] Example 1: Electro-excited trap like Figure 1-3 As shown, a safe and environmentally friendly handheld trap includes a cylinder. A gas generator is fitted inside the middle of the inner wall of the cylinder. The gas generator is filled with inert gas. The invention uses inert gas as the working medium, which is non-toxic and harmless. It is not a high-pressure container and there are no special risks in storage and transportation. Compared with spring devices, there is no metal fatigue problem. It has stable performance during long-term storage. Compared with pre-filled gas tanks, there is no need to replace consumables, making it more economical and environmentally friendly. A tray and a trap net cover are arranged sequentially above the gas generator. A trap net is accommodated between the tray and the trap net cover. The tray, trap net, and trap net cover are slidably fitted inside the cylinder. The upper end of the cylinder is threaded with an upper cover. An air jet hole is opened in the middle of the upper end face of the gas generator, and a rupture disc is installed inside the air jet hole. The gas generator is equipped with a heating element that generates heat when excited. The heat generated by the heating element causes the inert gas inside the gas generator to expand, thereby breaking the rupture disc. The ejected gas drives the tray, the capture net, and the capture net cover to pop out of the cylinder.

[0022] The heating element is an electric heating plate, which is electrically connected to the upper ends of two terminals. The two terminals are also fixedly connected to the bottom of the gas generator and the upper end of the insulating cylinder. The outer wall of the insulating cylinder is fixedly connected to the inner wall of the cylinder. A buffer spring is installed below the insulating cylinder, with its two ends fixedly connected to the bottom of the insulating cylinder and the bottom of the inner cylinder, respectively. The insulating cylinder is fitted inside the cylinder. Whether it is the buffer spring located below the insulating cylinder in the electrically excited type or the buffer spring located below the gas generator in the pull-out type, it can effectively absorb the recoil impact generated during gas ejection, protect the internal structure of the cylinder and the external grip feel, improve the user experience and equipment life.

[0023] The bottom ends of the two terminals are fixedly connected to one end of the two relay pieces respectively. The two relay pieces extend to the outside of the cylinder, and the other ends of the two relay pieces are fixedly connected to one end of the two terminals respectively.

[0024] The other end of the upper electrical connector is electrically connected to one end of the battery, and the battery is simultaneously fixedly connected to one end of both support plates.

[0025] The other end of each of the two support plates is fixedly connected to the inner wall of the battery casing, and the battery casing is overlapped on the outer surface of the cylinder.

[0026] Four threaded hole plates are fixedly installed on the outer surface of the battery casing, and the four threaded hole plates are respectively threaded to one end of four bolts.

[0027] The other end of each of the four bolts is threaded to one of the four threaded hole seats, which are all fixedly mounted on the outer surface of the cylinder.

[0028] A connecting block is provided between the lower contact plate and the other end of the battery. The end of the connecting block is fixedly connected to one end of the power button. The power button is fitted into a sleeve hole in the battery casing. A support spring is fitted on the outside of the power button. The two ends of the support spring are fixedly connected to the end of the power button and the outer surface of the battery casing, respectively. Under normal conditions, the power button pops out under the action of the support spring, and the circuit is broken. When the power button is pressed down, the connecting block inside it connects the battery circuit with the circuit corresponding to the terminal, and the current flows through the heating plate to make it heat up quickly.

[0029] Working principle: When using the electro-excited trap, the user can hold the cylinder with their hand, then twist the top cover to remove it from the top of the cylinder and adjust the cylinder angle. At this time, the user can press the power button to move the connecting block into the battery casing. When the upper and lower ends of the connecting block contact the bottom and lower side terminals of the battery respectively, the circuit between the heating plate and the battery is connected, causing the heating plate to work and generate heat to heat the inert gas in the gas generator. At this time, the inert gas expands and generates pressure, which tears the rupture disc along the groove, causing the inert gas to be ejected from the jet hole and ejecting the tray, trap net, and trap net cover from the cylinder.

[0030] Example 2: Pull-out type catcher like Figure 3-5As shown, a safe and environmentally friendly handheld trap includes a cylinder. A gas generator is fitted inside the cylinder, filled with an inert gas, preferably nitrogen, due to its low cost and extremely high safety. Above the gas generator, a tray and a trap net cover are arranged sequentially. The trap net cover is mainly used to fix the position of the net inside the cylinder, and its front end can be streamlined to reduce air resistance. The trap net is accommodated between the tray and the trap net cover. The trap net can be made of a soft and tough nylon mesh, and the mesh size can be adjusted according to the target organism. The net can be adjusted, and a counterweight ring can be provided at the edge of the net to ensure that it can fully unfold during flight. The tray, the net and the net cover can be slidably fitted into the cylinder. The upper end of the cylinder is threaded with an upper cover. An air jet hole is opened in the middle of the upper end face of the gas generator. A rupture disc is installed in the air jet hole. The rupture disc is provided with cross-shaped or star-shaped grooves to ensure that the opening is sufficient after tearing and the gas flows smoothly. The rupture disc material can be pure aluminum or stainless steel foil in annealed condition. Its bursting pressure can be accurately calibrated by the material, thickness and groove depth. The gas generator is equipped with a heating element that generates heat when excited. The heat generated by the heating element causes the inert gas inside the gas generator to expand, thereby breaking the rupture disc. The ejected gas drives the tray, the capture net, and the capture net cover to pop out of the cylinder.

[0031] The heating element is a friction-generating heating element, which includes a heating cylinder fixed inside the gas generator and a friction plate that can move relative to the heating cylinder to generate frictional heat.

[0032] The friction plate is connected to a pull ring on the outside of the cylinder by a pull rope. The pull rope is inserted into a through hole at the bottom of the gas generator. A lower cover is installed below the pull ring and is threaded to the bottom of the cylinder.

[0033] A buffer spring is installed directly below the gas generator, with its two ends fixedly connected to the bottom surface of the gas generator and the bottom surface inside the cylinder, respectively.

[0034] Working principle: When using the pull-type catcher, the user can hold the cylinder with their hand, then twist the upper cover to remove it from the top of the cylinder, and twist the lower cover to remove it from the bottom of the cylinder. Adjust the angle of the cylinder, and then pull the pull ring downwards to apply downward force to the friction plate using the pull rope. This causes the magnetic attraction between the two magnetic plates to disengage. At this time, the edge of the friction plate moves downwards quickly against the inner wall of the heating cylinder, causing the heating cylinder to generate heat through friction, which heats the inert gas in the gas generator. The inert gas expands and generates pressure, tearing the rupture disc along the groove, causing the inert gas to be ejected from the jet hole, which then ejects the tray, catch net, and catch net cover from the cylinder.

[0035] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
