The specific embodiment

Below in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4 the specific embodiment of the present utility model is made a detailed explanation.

A kind of padlock as shown in Figure 1, Figure 2, Figure 3 and Figure 4 is made of the lock body 1 and the lock bridge 2 of mutual coupling.Lock body 1 comprises the pellet shot from a slingshot 7 that lock housing 11, installation sleeve 5, lock core 8, ball 4 and many groups are arranged in rows.

Installation sleeve 5 is fixed in the mounting groove in the lock housing 11, installation sleeve 5 is by the rounded lock core mounting hole in the cross section of up/down perforation and with the pellet shot from a slingshot of lock core mounting hole vertical connection passage is installed and is constituted, the position of pellet shot from a slingshot installation passage is in the side of lock core mounting hole, it is be arranged in parallel up and down a plurality of that pellet shot from a slingshot is installed passage, lock core 8 is contained in the lock core mounting hole, the pellet shot from a slingshot 7 that many groups are arranged in rows is installed in pellet shot from a slingshot respectively and installs in the passage, pellet shot from a slingshot 7 one ends that are arranged in rows link to each other with lock core 8, and the other end fixes on the sidewall of installation sleeve 5.

Lock core 8 is made of with the rotating shaft 3 that is connected that is contained in its top copper core body 6, and copper core body 6 is contained in the lock core mounting hole, and pellet shot from a slingshot 7 one ends that are arranged in rows link to each other with copper core body 6.The sidewall that connects rotating shaft 3 is connected with ball 4, and the sidewall that connects rotating shaft 3 comprises two planes that are parallel to each other 33, and connects by arc surface 34 between two planes 33.The sidewall of connection rotating shaft 3 links to each other with ball 4 and controls ball 4 and laterally move the foldings that realize lock bridges 2.The plane 33 that connects in the rotating shaft 3 when unblanking links to each other with steel ball 4, and steel ball 4 moves inward, i.e. the close relatively connection rotating shaft 3 in position, and outermost steel ball 4 lateral walls break away from the fore shaft of lock bridge 2, and lock bridge 2 is opened; When sealed, the arc surface 34 that connects in the rotating shaft 3 links to each other with steel ball 4, and steel ball 4 is connected rotating shaft 3 to extrapolation, and promptly away from connection rotating shaft 3, outermost steel ball 4 lateral walls block the fore shaft of lock bridge 2 relatively in the position, and lock bridge 2 is by sealed.

Be provided with the keyhole 61 of up/down perforation in the copper core body 6, the bottom of copper core body 6 is on the bottom surface of lock body 1, and promptly keyhole 61 bottoms are on the bottom surface of lock body 1.Connect the groove 31 that rotating shaft 3 bottoms are provided with the ccontaining key corresponding with keyhole 61, key end can be inserted in the groove 31 during use, and promptly key can directly drive simultaneously when rotating copper core body 6 and connect rotating shaft 3 and rotate.Copper core body 6 tops are provided with the draw-in groove vertical with keyhole 61, the bottom that connects rotating shaft 3 is provided with the fixture block 32 that snaps in the draw-in groove, vertical and the groove 31 of the groove 31 that connects rotating shaft 3 bottoms and fixture block 32 is divided into left and right sides two parts with fixture block 32, when key end can be inserted groove 31, the end was between the two-part fixture block 32 in the left and right sides when key inserted groove, it is the fixture block 32 that the end sidewalls of key can be blocked groove 31 the right and lefts, key can prop up fixture block 32 and conveniently puts forth effort during rotation, make key turns more smooth and easy, connected mode by draw-in groove and fixture block 32 realizes copper core body 6 and the connection that is connected rotating shaft 3, has realized connecting the rotation of rotating shaft 3 with copper core body 6.Connect the rotating shaft 3 general steels that adopt, reduced cost of production.
