Description

Technical Field

[0001] The utility model belongs to the technical field of training grenades, in particular to a training grenade with a retractable handle. Background Art

[0002] Training grenades are generally used for new recruits to train in throwing weapons. They are similar in appearance to real grenades and can imitate the throwing feel of real grenades. At the same time, they will not explode, ensuring the safety of new recruits' training.

[0003] At present, the Chinese utility model with the announcement number of CN205957826U discloses a simulated training hand grenade, whose structure includes: a protective cover, a detonating device, a handle, a fixing rod, a screw, a screw hole, a simulated training hand grenade head, a positioning device, and a simulated explosion device; the protective cover is connected to the detonating device, the detonating device is connected to a handle, the handle is connected to a fixing rod, the fixing rod is connected to a simulated training hand grenade head, and the simulated training hand grenade head is provided with a screw hole. The beneficial effect of the utility model is that when the pull ring of the simulated training hand grenade is pulled, the pull ring and the inner wall of the placement hole produce friction, such a design makes the feel of the trainee when pulling the pull ring closer to the feel of pulling a real hand grenade, thereby helping to improve the training effect, and the simulated training hand grenade can be reused, the explosion of the simulated training hand grenade is made more realistic by the provided simulated explosion device, and the simulated training hand grenade is made easier to be retrieved by the provided positioning device.

[0004] There are many types of existing training grenades, which are generally manufactured according to the appearance of real grenades, including training grenades made by imitating traditional Type 67 grenades. However, since such training grenades have a long handle and the handle cannot be retracted, they will take up a large space whether transported or carried. At the same time, such existing training grenades cannot increase their own weight and cannot gradually increase the difficulty of throwing training. Therefore, the actual throwing training effect of the training grenades is poor and the practicality is low. Utility Model Content

[0005] The utility model aims to provide a training hand grenade with a retractable handle, which has the advantages of being convenient for transporting and carrying the training hand grenade and improving the actual training effect of the training hand grenade.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a training grenade with a retractable handle, comprising an outer shell, an inner tube fixedly connected to the interior of the outer shell, a first extension handle, a second extension handle, and a third extension handle arranged on one side of the bottom of the inner tube, the surface of the second extension handle being slidably connected to the inner wall of the third extension handle, the surface of the first extension handle being slidably connected to the inner wall of the second extension handle, the surface of the third extension handle being slidably connected to the inner wall of the inner tube, the bottom of the third extension handle being fixedly connected to a bottom plate, and magnet blocks which are magnetically attracted to each other are fixedly connected to the bottom of the outer shell and the top of the bottom plate.

[0007] By adopting the above technical solution, the handle of the training grenade can be extended up and down at the bottom, so that it can be pulled out when needed and pushed in and retracted when not in use. Thereby reducing the size of the training grenade, reducing the space occupied, and facilitating transportation and carrying. By opening the extension shell and then adding a counterweight ring, and fixing it between the extension shell and the inner tube. The weight of the training grenade is increased, so that the personnel need more force when throwing the training grenade, thereby increasing the difficulty of throwing and improving the actual training effect of the training grenade.

[0008] The utility model is further configured as follows: the inner wall of the outer shell is threadedly connected to an extended outer shell sleeved on the surface of the inner cylinder, the inner wall of the extended outer shell is slidably connected to a counterweight ring slidably sleeved with the surface of the inner cylinder, and the top of the extended outer shell is fixedly connected to a fixed cover.

[0009] By adopting the above technical solution, the weight of the training grenade is increased, and personnel need greater strength when throwing the training grenade, thereby increasing the difficulty of throwing and improving the actual training effect of the training grenade.

[0010] The utility model is further configured as follows: the inner tube and the inner walls of the second extension handle and the third extension handle are all provided with sliding grooves, and the top and bottom of the first extension handle and the bottom of the second extension handle are fixedly connected with limit plates slidably connected to the sliding grooves.

[0011] By adopting the above technical solution, the sliding distance of the handle is limited to prevent the first extension handle and the second extension handle from sliding out of the inner tube, the first extension handle and the third extension handle respectively.

[0012] The utility model is further configured as follows: a simulation lead is arranged at the bottom of the bottom plate, and a rubber plug which is slidably plugged with the bottom plate is fixedly connected to the top of the simulation lead.

[0013] By adopting the above technical solution, the rubber plug is inserted into the interior of the bottom plate, and the friction between the rubber plug and the bottom plate is used to fix the simulated lead and simulate the feeling of pulling the simulated lead.

[0014] The utility model is further configured as follows: the surfaces of the first extension handle, the second extension handle and the third extension handle are all provided with anti-slip patterns.

[0015] By adopting the above technical solution, the friction force when holding the handle is improved and the anti-slip performance is enhanced.

[0016] The utility model is further configured as follows: a torsion plate is fixedly connected to the top of the fixed cover.

[0017] By adopting the above technical solution, it is easy to twist the torsion plate to drive the extension shell to rotate, which is convenient for operation.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. The handle of the training grenade can be extended up and down at the bottom, so that it can be pulled out when needed and pushed in and retracted when not in use. This reduces the size of the training grenade, reduces space occupied, and is easy to transport and carry;

[0020] 2. By opening the extension shell and adding a weight ring, and fixing it between the extension shell and the inner tube, the weight of the training grenade is increased, so that personnel need more force when throwing the training grenade, thereby increasing the difficulty of throwing and improving the actual training effect of the training grenade.
