Abstract
A duties insurance institution for hand grenade fuze, by draw ring, safety plug, hold sheet, insurance spring etc. and form, draw ring passes from the draw ring hole of safety plug one end, and safety plug passes from fuze body and two flangings of holding sheet, and the other end of safety plug has clip groove.Insurance spring is half of square frame shape, and its one end is turned to the lock ring passed through for safety plug, and the other end is made into may be stuck in the clip in clip groove.Only have when clip opens in clip groove, shift out, and after extracting safety plug out, these duties insurance could be removed.Thus the security performance making duties insure has great raising, on the grenade being applicable to various model.
Description
Technical field: the duties insurance institution that the present invention relates to a kind of hand grenade fuze.
Background technology: at present, the duties insurance institution of domestic and international grenade general all by draw ring, safety plug, insurance spring, hold sheet and form, safety plug passes from fuze body and two flangings holding sheet, draw ring is buckled in the boss openings groove of fuze body, to realize, to safety plug and the locking of holding sheet, reaching the object of duties insurance.During use, draw ring be pulled out in fuze body boss openings groove, and then be pulled out by safety plug, the elastic force of release insurance spring, holds sheet and is flicked, and removes duties insurance.This kind of mode, draw ring easily gets loose in fuze body boss openings groove, just cannot automatically reset once draw ring gets loose, if meet external force again by safety plug pull-out or release, the duties insurance of grenade will be lost efficacy, thus caused security incident.
Summary of the invention: the object of the present invention is to provide a kind of external force cannot remove the duties insurance institution of a kind of hand grenade fuze of duties insurance.
The present invention by draw ring, hold sheet, safety plug, insurance spring form, draw ring passes from the draw ring hole of safety plug one end, and safety plug passes from fuze body and two flangings holding sheet, and described insurance spring entirety is half of square frame shape, its one end is wound into lock ring, and the other end is made into clip; Safety plug passes from lock ring, and the other end of safety plug has clip groove, and clip is stuck in clip groove.
Because the present invention utilizes insurance spring by safety plug clamping locking, only have and first safety plug rotation is made the clip on insurance spring open and shifted out in clip groove, after also will pulling out safety plug, these duties insurance could be removed.Again because clip is placed within clip groove, clip groove has protective effect to clip, and general external force directly cannot contact with clip, it more cannot be made to open and shift out in clip groove.Even if there is external force to make clip open by chance, as long as this external force could not make clip shift out in clip groove, after external force is eliminated, clip can automatically reset again, again realizes the locking to safety plug.Visible, for existing all kinds of duties insurance, security performance of the present invention has had very big raising.The present invention is applicable on the grenade of various model.
Accompanying drawing illustrates: Fig. 1 is structural representation of the present invention, and the parts that in figure, safety plug passes through are broken away; Fig. 2 is the schematic perspective view of insurance spring of the present invention.
Detailed description of the invention: draw ring of the present invention (1) is made up of steel wire encircling 1 ~ 2 circle, also can replace with normal key ring.Draw ring (1) passes from the draw ring hole of safety plug (2) one end, is entangled by safety plug (2) as key kit.Safety plug (2) passes from fuze body (5) and two flangings of holding sheet (4).The shape of insurance spring (3) is as shown in accompanying drawing (2), and entirety is half of square frame shape, and its one end is wound into lock ring (6) and passes therethrough for safety plug (2), and the number of turns of lock ring (6) is 1-2 circle.The other end of insurance spring (3) is made into clip (7), and clip (7) will have enough elasticity, can be clipped in tightly in clip groove (8).Clip (7) can have various shape, as side's end shape, semicircle etc., but is good with U-shaped.Safety plug (2) such as can be at the thick straight-bar, but be preferably divided into thickness two sections, the external diameter of thicker a section is greater than the internal diameter of lock ring (6), in case lock ring slips over, the external diameter of thinner one section is less than the internal diameter of lock ring (6), so that it freely rotates and comes in and goes out in lock ring.There is draw ring hole one end of safety plug (2), and draw ring (1) passes from draw ring hole, and when safety plug (2) is divided into thickness two sections, draw ring hole should be placed on thicker one section; The other end of safety plug (2) has clip groove (8), when safety plug (2) is divided into thickness two sections, clip groove (8) should the end of thinner a section.Clip groove (8) can only be opened in the side of safety plug (2), but preferably both sides are all opened, and symmetry etc. are dark.
