Description

Technical Field

[0001] This invention relates to the field of safety devices for training the throwing of handleless grenades, and more specifically, to a grenade drop safety device for training the throwing of handleless grenades. Background Technology

[0002] Hand grenades are an important weapon for close-quarters combat, possessing advantages such as small size, light weight, high power, and ease of operation. Hand grenade throwing training is a fundamental subject in the military training syllabus and also a course for new recruits. Due to its high risk factor, accidents occur frequently.

[0003] Currently, domestic grenade throwing protection measures involve setting up blast trenches in front of breastworks. A missed grenade falls into these trenches, limiting the direction of grenade fragments. Blast shelters large enough to accommodate multiple people are located to the left and right rear of the throwing area. In the event of a missed grenade, the throwing commander and safety officer pull the thrower into the shelter, achieving the desired protection. However, these existing measures also have safety hazards: the detonation time of a grenade is approximately 2.8 to 4 seconds. If the commander or thrower does not react in time, their lives could be in danger. In addition, Chinese utility model patent CN206905641U discloses a safety device for training the throwing of handleless grenades. During training, if a handleless grenade accidentally slips from the thrower's hand and falls, this safety device eliminates the need for the thrower to quickly escape, dodge, or lie down. The handleless grenade automatically falls onto the portable automatic safety device and rolls along the drop hole on the device's surface into the bottom of the device, exploding inside a sealed steel plate. This prevents injury to the thrower and damage to the device itself. This device is designed to ensure the safety of trainees. However, in practical applications, because the area between the bullet holes of the safety device is a flat surface (for the thrower to stand on), when a handleless grenade is accidentally released and falls, it may land on the flat surface at a vertical or near-vertical angle. In this case, the handleless grenade will bounce multiple times before finally falling into the bullet hole. This process sometimes takes longer than the explosion time of the handleless grenade (at which point, the handleless grenade explodes on the flat surface or near the opening of the bullet hole), leading to safety failure and casualties.

[0004] Therefore, there is a need to provide a safer grenade drop protection device for training with handleless grenades. Summary of the Invention

[0005] The purpose of this invention is to provide a safer grenade drop avoidance device for training in throwing handleless grenades.

[0006] To achieve the above objectives, the present invention provides a grenade drop avoidance device for training throwing of handleless grenades. The grenade drop avoidance device includes a main body having a throwing training surface and a guide structure disposed on the throwing training surface. The main body is provided with a plurality of drop holes extending from the throwing training surface toward the interior of the main body. The guide structure is used to guide handleless grenades falling on the throwing training surface into the drop holes.

[0007] Furthermore, the guide structure includes protrusions and rounded corners disposed between adjacent bullet holes.

[0008] Furthermore, the extension directions of the plurality of bullet holes are parallel to each other, and each bullet hole includes multiple segments that are connected in sequence and extend inside the body in multiple different directions.

[0009] Furthermore, each of the aforementioned hole segments is an oblique polygonal prism, and the cross-section of each of the aforementioned hole segments is a regular polygon. The protrusion is located on the throwing training surface at the location opposite to the intersection point of the oblique polygonal prism's edges, and the rounded corner is located on the throwing training surface at the location opposite to the edges of the oblique polygonal prism's edges.

[0010] Furthermore, each of the aforementioned hole segments is an oblique hexagonal prism, and the cross-section of each of the aforementioned hole segments is a regular hexagon. The plurality of bullet holes are arranged in a honeycomb pattern on the throwing training surface of the main body.

[0011] Furthermore, the main body also has a base surface opposite to the throwing training surface, and the bullet hole extends from the throwing training surface toward the interior of the main body until it penetrates the base surface.

[0012] Furthermore, the main body is provided with a buffer energy-absorbing structure on the throwing training surface.

[0013] Furthermore, the buffer energy-absorbing structure is a powder-coated layer and / or a soft adhesive layer.

[0014] Furthermore, the bullet drop avoidance device also includes a base, and the bottom of the main body is mounted on the base.

[0015] Furthermore, the base is provided with a mounting groove for injecting buffer solution, and the bottom of the main body is installed in the mounting groove so that the buffer solution can seep into the bullet drop hole.

[0016] The drop protection device for hand grenade throwing training of the present invention has a guiding structure on the throwing training surface to guide the hand grenade falling on the throwing training surface into the drop hole. Therefore, in actual application, when the hand grenade is accidentally dropped, the guiding structure can guide the hand grenade falling on the throwing training surface into the drop hole within its explosion time, ensuring that the explosion of the hand grenade occurs in the drop hole. It can be seen that the drop protection device for hand grenade throwing training of the present invention has the advantage of higher safety.

[0017] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] This invention provides a grenade drop avoidance device for training in throwing handleless grenades, specifically, as follows: Figure 1 and Figure 2 As shown, the grenade drop avoidance device includes a main body 1 with a throwing training surface and a guide structure 2 disposed on the throwing training surface. The throwing training is provided for throwers to practice throwing handleless grenades on it. The main body 1 is provided with a plurality of drop holes extending from the throwing training surface toward the interior of the main body 1. The guide structure 2 is used to guide handleless grenades falling on the throwing training surface into the drop holes.

[0027] The drop protection device for hand grenade throwing training of the present invention features a guide structure 2 on the throwing training surface to guide the hand grenade into the drop hole. In practical applications, if a hand grenade accidentally slips from the hand and falls, this guide structure 2 can guide the grenade into the drop hole within its detonation time, ensuring that the grenade explodes within the drop hole. Therefore, the drop protection device for hand grenade throwing training of the present invention offers higher safety. Furthermore, the drop protection device for hand grenade throwing training of the present invention also has the advantages of simple structure, low cost, and ease of promotion.

[0028] It should be noted that the specific structural forms of the main body 1, the guide structure 2, and the bullet drop hole, as well as the materials used to manufacture the main body 1 and the guide structure 2, can be customized as needed, and these all fall within the scope of the technical concept of this invention. For example, the main body 1 can be formed by bending and welding or casting of an explosion-resistant and impact-resistant metal plate; correspondingly, the material of the guide structure 2 is suitable for placement on the throwing training surface, such as steel, aluminum alloy, or composite materials. The specific forms of the above features will be illustrated below with specific examples; the bullet drop hole can be a circular hole or a polygonal hole (e.g., a square hole), etc.

[0029] In the grenade drop avoidance device for training throwing handleless grenades according to the present invention, specifically, as shown in the example... Figure 2 As shown, the guide structure 2 includes a protrusion 21 and a rounded corner 22 disposed between adjacent drop holes. When a handleless grenade is accidentally released and falls onto the throwing training surface at a vertical or near-vertical angle, the protrusion 21 and the rounded corner 22 can deflect the secondary bounce angle of the handleless grenade, preventing it from bouncing multiple times and / or bouncing to a high position and failing to fall into the drop hole within the explosion time. In addition, the protrusion 21 can also increase the friction of the thrower on the throwing training surface to prevent the thrower's feet from slipping.

[0030] More specifically, in the aforementioned grenade drop protection device, the extension directions of the plurality of bullet drop holes are parallel to each other, and each bullet drop hole includes multiple segments connected in sequence and extending inside the main body 1 in multiple different directions, thereby using the corner-shaped bullet drop holes to prevent steel balls and fragments from the explosion of the handleless grenade from ejecting from the bullet drop holes and injuring the thrower. Further specifically, as... Figure 2As shown, each of the aforementioned hole segments is an oblique polygonal prism, and the cross-section of each of the aforementioned hole segments is a regular polygon. The protrusion 21 is located on the throwing training surface at the point where it intersects with the edge of the oblique polygonal prism, and the rounded corner 22 is located on the throwing training surface at the point where it intersects with the edge of the oblique polygonal prism. More specifically, as... Figure 1 As shown, each of the holes is an oblique hexagonal prism, and the cross-section of each of the holes is a regular hexagon. The multiple bullet holes are arranged in a honeycomb pattern on the throwing training surface of the main body 1, so that the bullet holes are arranged as compactly as possible on the throwing training surface, making it easier for the handleless grenade to fall into the bullet holes.

[0031] It should be noted that the specific shape and size of the bullet hole correspond to the specific shape and size of the thrown handleless grenade. At the same time, the specific shape and size of the bullet hole will affect the stability of the thrower's standing training. The specific shape and size of the protrusion 21 and the rounded corner 22 also correspond to the specific shape and size of the bullet hole. For example, when the handleless grenade is the Type 82-2 handleless grenade, the cross-section of each segment of the bullet hole is a regular hexagon, and the side length of the regular hexagon is between 10 and 12 centimeters. The vertical height of the protrusion 21 is between 1 and 4 millimeters, and the radius of the rounded corner 22 is between 1 and 2 millimeters.

[0032] More specifically, in the above-mentioned bullet drop avoidance device, the main body 1 also has a base surface opposite to the throwing training surface, and the bullet drop hole extends from the throwing training surface toward the interior of the main body 1 until it penetrates the base surface.

[0033] In the grenade drop avoidance device for training throwing handleless grenades according to the present invention, specifically, the main body 1 is provided with a buffer energy-absorbing structure on the throwing training surface, thereby buffering and absorbing the energy of the handleless grenade falling on the throwing training surface and preventing the handleless grenade from bouncing to a higher position. More specifically, the buffer energy-absorbing structure is a powder-coated layer and / or a soft adhesive layer.

[0034] In the grenade drop avoidance device for training throwing handleless grenades according to the present invention, specifically, the grenade drop avoidance device further includes a base 3, on which the bottom of the main body 1 is mounted, thereby supporting the main body 1 and preventing it from sinking. More specifically, the base 3 is provided with an installation groove for injecting buffer solution, and the bottom of the main body 1 is mounted in the installation groove, so that the buffer solution can seep into the grenade drop hole. The buffer solution injected into the installation groove can seep into the drop hole and quickly buffer the handleless grenade falling into it, reducing the possibility of rebound and simultaneously adhering to the steel balls and fragments generated after the handleless grenade explodes, reducing blast damage.

[0035] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0037] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
