Abstract
The utility model relates to a delay removal safety device for detonators. The utility model adopts an entire steel wall to make a safety belt, a safety piece and the steel ball to form a mechanism similar to a bearing, a support piece and the steel ball are utilized to isolate the safety piece from the safety belt so that the safety piece and the safety belt can not interfere each other and work independently so that the safety belt can reliably achieve the functions of time delay and safety removal in the process of fuse.
Description
The utility model relates to a kind of weapon device, especially a kind of whizbang time-delay arming device of fuse.
Present known employing safety belt is as the whizbang fuse of time-delay arming device, have plenty of and directly be entangled in safety belt on the safety piece, have plenty of safety belt is entangled on the safety piece centrifugal, the fuse of this class formation, in the launch and flight of bullet, because the effect of various environmental forces can make insurance reliably free, and fuse can not be acted on.
Goal of the invention of the present utility model is: develop a kind of safety belt is in reliably open and be not subjected to safety piece in the time-delay arming device that holds together.
Technical solution of the present utility model is: the time-delay arming device is made up of insurance tape drum, safety belt, steel ball, safety piece, spring and support member.On safety piece, have a cannelure, 2 or 2 above steel balls block cannelure and form a structure that is similar to bearing, safety piece is loaded in the support member, the annular boss of support member props up steel ball, safety belt is wrapped on the annular boss outer wall of steel ball and support member, annular boss and steel ball on supported of safety belt and the safety piece separate, thereby guarantee insurance band and safety piece do not disturb mutually, independently of one another, solved the problem that known safety belt mechanism exists, if being contained in the bottom of shell, fuse can not change the cannelure on the safety piece into annular boss, variation requirement according to these safeties installation site in fuze body, support member and annular boss can be made two parts and be not one in addition, during use annular boss is embedded in the support member and get final product.Operation principle of the present utility model is: during the shell emission, after bullet went out thorax, tangent line inertia force disappeared, and safety belt takes the lead to begin from the outer ring under action of centrifugal force, forms band bridge and from coil to coil and opens.The action of centrifugal force that last safety belt inner ring is produced by steel ball is opened fully, and be close to opened safety belt inner chamber, discharge safety piece to steel ball necessary space is provided, safety piece discharges explosion-proof part, this moment, bullet flew beyond gun muzzle safe distance, thereby realized the purpose of the remote arming of fuse.
The utility model is compared with known safety belt time-delay arming device, can make the motion of safety belt not be subjected to the interference of safety piece, is in the state that can reliably open, realizes time-delay and removes two kinds of functions of insurance, makes the fuse time-delay ignite bullet reliably.
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Accompanying drawing is the cross-sectional view of a kind of fuse with the time-delay arming device.
Accompanying drawing is described structural principle of the present utility model in detail, this time-delay arming device is by insurance tape drum 1, steel ball 2, safety belt 3, safety piece 4, support member 5, spring 6, explosion-proof part 7, explosion-proof part seat 8 and firing pin 9 are formed, be processed with a circular hole with the level at support member 5 centers, spring 6 is placed on the step in the circular hole, safety piece 4 is processed into thickness two parts, firing pin 9 is equipped with in thin termination portion, safety piece 4 is inserted in support member 5 holes, the step that forms with the thickness two ends compresses spring 6, the butt end of safety piece 4 is inserted in the blind hole of explosion-proof part 7, firing pin 9 inserts in the aperture of explosion-proof part 7, have a cannelure 10 in safety piece 4 thick end portions, several steel balls 2 are placed on the support member 5 top annular boss 11, be stuck in the cannelure, again with safety belt 3 hoop on the outer wall of the annular boss 11 of steel ball 2 and support member 5, will insure tape drum 1 again and cover safety belt 3 and support member 5.
Claims (3)
1, a kind of fuse time-delay arming device, mainly form by insurance tape drum (1), safety belt (3), safety piece (4), support member (5), spring (6), explosion-proof part (7), it is characterized in that: safety piece (4) has a cannelure (10), have the steel ball (2) more than 2 or 2 to be stuck in the cannelure, the support member (4) that has annular boss (11) separates safety piece (4) and safety belt (3) jointly with steel ball.
2, a kind of fuse according to claim 1 is characterized in that: when fuse is installed in the shell bottom, be processed with ring-shaped step on safety piece (4) with the time-delay arming device.
3, a kind of fuse according to claim 1 and 2 time-delay arming device is characterized in that: support member (5) is not one with annular boss (11).
