Description

Double row ball ring latch with protector

The utility model relates to spring padlock, particularly a kind of Safety padlock with the two axis of two row pellets shot from a slingshot.

The padlock of the biserial pellet shot from a slingshot that exists in the prior art, as application number is 88210935, name is called the patent of the civilian safety lock of two-sided pellet shot from a slingshot, exist a fatal weakness, be that key is easy to duplicate with soft material compacting, lock is also opened by " master key " easily, and lock hanging also can be fallen by sled, thereby exists deficiency.

The purpose of this utility model is to provide the Safety padlock of a kind of two pellets shot from a slingshot of pick-proof, two axis and the key that is difficult for being replicated thereof.

The biserial pellet shot from a slingshot of the utility model indication adds Safety padlock by lock hanging, lock body, lock core and key are formed, it is characterized in that in the keyhole of lock core, being equipped with insurance axle (7), be fixed on anti-inclined to one side sheet (18) and back-moving spring (8) on the insurance axle, the top of insurance axle is fixed with insurance card (19), this insurance card is positioned at corresponding insurance draw-in groove on the inverted draw cut of lock core and the lock body, they constitute first insurance institution, the surface that the top of lock core also is fixed with hollow has the reducing core body (4) of cannelure, the reducing core body will be with in the groove in axis (9) the jacking lock hanging of extension spring (24), core body (4) centre bore has an insurance axle (11) that is with back-moving spring (22), its two ends correspond respectively to the groove on insurance card (19) and the cover plate, they constitute second insurance institution, described lock core, lock hanging and insurance institution pack into behind the inner chamber of lock body, are fixed as one by cover plate (2) sealing and with lock body at the top; Key is formed by two stamping forming sheet metal riveteds, have on it one with insurance axle (7) corresponding cavity, surfaces of keys has the contraposition circular trough corresponding with the round end pellet shot from a slingshot of lock core.

The detailed structure that said structure of the present utility model can provide with reference to the accompanying drawings further specifies.

The utility model has following accompanying drawing:

Accompanying drawing 1 is the main pseudosection of the utility model padlock;

Accompanying drawing 2 is the A-A cut-away view among Fig. 1;

Accompanying drawing 3 is the upward view of the utility model padlock;

Fig. 4 is the schematic diagram of the utility model key.

Referring to accompanying drawing, two row pellets shot from a slingshot are housed in the lock body, the key (15) that one side is processed with swallow-tail form protruding (17) inserts corresponding with it, be processed with in the keyhole of dovetail groove (20), at this moment, insurance axle (7) inserts in the cavity of keys (15) and since the contraposition circular groove (14) on the key (15) not with lock core (6) in round end pellet shot from a slingshot (12) to good position, thereby key, can not drive lock core and rotate.After key inserts to pressing down, make insurance card (19) rising on the one hand and leave draw-in groove, make on the key contraposition circular groove (14) and interior round end pellet shot from a slingshot (12) contraposition of lock core on the other hand, with round end pellet shot from a slingshot jack-up, make the tack pellet shot from a slingshot (13) that compressed by marble spring (21), thereby lock core and reducing core body (4) are rotated, when the reducing core body revolves when turning 90 degrees, the two ends of major diameter are removed, remove top power to axis (9), axis is withdrawed from the groove from lock hanging (1) under the effect of extension spring (24), and an end of lock hanging at this moment can separate from lock body (3), and the other end is blocked by spacer pin (16).Axis (9) one ends are ducted body, are packaged with top spring (25) and steel ball (10) in it, and steel ball is withstood on by the top spring on the groove of reducing core body, and extension spring (24) one ends on the axis withstand on the lock body, and an end withstands on the boss of axis steel ball one end.Reducing core body (4) is fixed as one with lock core (6) top, accompanies pad (5) therebetween and drops out to prevent insurance axle (11) and spring (22).When key unlocking, pressing down excessively, insurance card (19) is risen and will insure (11) jack-up and be located in the groove (23) on the closedtop cover plate (2) and lock core can't be rotated.

Find out from said structure, the utlity model has good safety, promptly key will never be duplicated by soft material pressing mold, also is difficult for being prepared by general technology.Lock can not opened by other key or similar item yet, can replace existing padlock and is used for family and unit.
