Abstract
Description
Technical Field
[0001] This utility model relates to the field of advanced manufacturing and automation technology, specifically a simple mechanical delay triggering device. Background Technology
[0002] The mechanical grenade is a throwable weapon with unique properties. Its most distinctive feature is its "rapid explosion" attribute, which means that once it is thrown, it will explode immediately upon contact with any obstacle, rather than waiting to explode after reaching its maximum distance.
[0003] The "rapid explosion" attribute of mechanical grenades gives them high flexibility and tactical value in actual combat. Throwers can use this characteristic for rapid deployment and tactical deception, such as setting traps on paths the enemy might take, or detonating them suddenly at a critical moment to cause unexpected damage.
[0004] Currently, there are some drawbacks to rapidly exploding mechanical grenades. For example, due to their rapid explosion, they require a high level of skill from the thrower. In certain special environments, such as confined spaces or situations where precise control of the explosion time is needed, existing mechanical grenades cannot meet the requirements for delayed explosions. Therefore, there is a need for an improved mechanical delay triggering device. This device can accurately control the explosion time of the mechanical grenade. Without changing the original rapid explosion characteristics of the mechanical grenade, a delay mechanism can be set to achieve delayed explosions, thereby improving the strategy and flexibility of combat. Utility Model Content
[0005] The purpose of this invention is to provide a simple mechanical delay triggering device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a simple mechanical delay triggering device, comprising a housing made of toothed cast iron, a matching bottom cover installed at the bottom of the housing, a pyrotechnic device located at the center of the bottom cover, a speed reduction gear mechanism installed inside the housing, and a safety structure installed at the head of the housing.
[0007] Preferably, the safety structure includes a locking lug and a safety lever. The locking lug is mounted on the head of the housing by a torsion spring. The locking lug and the safety lever are provided with safety pin holes, and a safety pull pin is installed inside the safety pin holes. The safety lever is installed to one end of the locking lug via the safety pull pin, and the other end of the locking lug abuts against the impact pin.
[0008] Preferably, the impact pin is installed inside the stop cylinder, and a firing pin spring is sleeved on the outside of the impact pin. One end of the firing pin spring is connected to the top of the stop cylinder, and the other end of the firing pin spring is connected to the lower part of the impact pin.
[0009] Preferably, one side of the impact pin is provided with a firing pin groove, and one side of the firing pin groove is provided with a matching rocker plate. The rocker plate is movably installed inside the housing. A push pin is provided above one side of the rocker plate, and the top of the push pin is in contact with the locking latch.
[0010] Preferably, the back of the rocker is provided with a gear, which meshes with a reduction gear mechanism.
[0011] Preferably, a pendulum is also provided inside the lower part of the outer casing, and the pendulum is connected to the bottom of the outer casing.
[0012] This invention provides a simple mechanical delay triggering device. It has the following advantages:
[0013] (1) This utility model sets a delay mechanism without changing the original rapid detonation characteristics of mechanical hand grenade. During the release process, the deceleration gear mechanism effectively prolongs the detonation time, relieves the safety pressure on the operator, and also ensures the reliability of the detonation process, thus achieving delayed explosion and delay effect.
[0014] (2) By designing a deceleration gear mechanism, when the impact pin is released, it will move downward rapidly due to the elastic force of the impact pin spring. At the same time, the impact pin groove drives the rocker plate to rotate. The gear on the back of the rocker plate is linked with the deceleration gear mechanism to limit the downward speed of the impact pin. In this way, the explosion time can be precisely controlled to a certain extent, and the delay effect is significant, providing combat personnel with more tactical options.

[0016] In the diagram: outer casing 21, bottom cover 22, reduction gear mechanism 23, rocker plate 24, ejector pin 25, pendulum 26, locking ferrule 31, safety handle 32, safety pull pin 33, impact pin 34, firing pin spring 35, stop sleeve 36. Detailed Implementation
[0017] 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.
[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0019] A preferred embodiment of the simple mechanical delay triggering device provided by this utility model is, for example... Figure 1 As shown: A simple mechanical delay triggering device includes a housing 21 made of toothed cast iron, and a matching bottom cover 22 installed at the bottom of the housing 21. A pyrotechnic device is provided at the center of the bottom cover 22. When pressure or friction is applied, a spark will be generated, which will ignite the delay gunpowder. The gunpowder takes four to five seconds to reach the detonator. The detonator burns and ignites the explosive. A deceleration gear mechanism 23 is installed inside the housing 21.
[0020] The head of the outer casing 21 is equipped with a safety structure, which includes a locking tenon 31 and a safety lever 32. The locking tenon 31 is installed on the head of the outer casing 21 by a torsion spring. The locking tenon 31 and the safety lever 32 are provided with safety pin holes. A safety pull pin 33 is installed in the safety pin holes. The safety lever 32 is installed on one end of the locking tenon 31 by the safety pull pin 33. The other end of the locking tenon 31 abuts against the impact pin 34. The impact pin 34 is installed in the stop cylinder 36, and a firing pin spring 35 is sleeved on the outside of the impact pin 34. One end of the firing pin spring 35 is connected to the top of the stop cylinder 36, and the other end of the firing pin spring 35 is connected to the lower part of the impact pin 34.
[0021] In this embodiment, further, by holding the safety lever 32, when the safety pin 33 is pulled out from the safety pin hole and the grenade is thrown, the safety lever 32 is released. At this time, the locking jaw 31 changes and no longer blocks the impact pin 34. When the impact pin 34 is released, it will move downward rapidly due to the elastic force of the firing pin spring 35. At the same time, the firing pin groove drives the rocker plate 24 to rotate. The gear on the back of the rocker plate 24 is linked with the reduction gear mechanism 23 to limit the downward speed of the firing pin. When the impact pin 34 is freed from the restriction of the rocker plate 24, it falls rapidly and hits the pyrotechnic device installed in the center of the bottom cover, causing it to detonate and completing the triggering process of the time-delay fuse.
[0022] The impact pin 34 has a firing pin groove on one side, and a matching rocker plate 24 is provided on one side of the firing pin groove. The rocker plate 24 is movably installed in the housing 21. A ejector pin 25 is provided above one side of the rocker plate 24, and the top of the ejector pin 25 is in contact with the locking tenon 31.
[0023] During reset, press the push rod 25 into the device and then push the impact pin 34 in until the rocker plate 24 can control the impact pin 34.
[0024] The back of the rocker 24 is provided with a gear, which meshes with the reduction gear mechanism 23 to limit the descent speed of the impact pin 34. When the rocker 24 is subjected to an external force, the rocker 24 rotates, causing the gear to rotate. The gear drives the reduction gear mechanism, thereby causing the impact pin 34 to descend slowly.
[0025] A pendulum 26 is also provided inside the lower part of the outer casing 21. The pendulum 26 is connected to the bottom of the outer casing 21. Its function is to provide sufficient inertial force when the mechanical delay trigger device is started, so as to ensure the stability and reliability of the device.
[0026] In use, by holding the safety lever 32, when the safety pin 33 is pulled out from the safety pin hole and the grenade is thrown, the safety lever 32 is released. At this time, the locking jaw 31 changes and no longer blocks the firing pin 34. When the firing pin 34 is released, it will move downward rapidly due to the elastic force of the firing pin spring 35. At the same time, the firing pin groove drives the rocker plate 24 to rotate. The gear on the back of the rocker plate 24 is linked with the reduction gear mechanism 23 to limit the downward speed of the firing pin. When the firing pin 34 is freed from the restriction of the rocker plate 24, it falls rapidly and hits the pyrotechnic device installed in the center of the bottom cover, causing it to detonate and completing the triggering process of the time-delay fuse.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
