The specific embodiment
See also Fig. 1 to shown in Figure 3, the utility model comprises a shell 1, a lock body 2, a tumbler 3 and a base 4, wherein:
Described shell 1 is to be a hollow cylinder, for inserting described base 4, described tumbler 3 and described lock body 2 in regular turn, its periphery one side is provided with two perforation 11, for plugging of pin 13, be concaved with a scrobicular ring 12 in one end outboard peripheries in addition, establish for the lid of an enclosing cover 6 and use dustproof, waterproof;
Described lock body 2, be to comprise a core 21 and a lock tube 22, the center of wherein said lock tube 22 has a perforation 221, supply the sheathed of described core 21, its periphery has a jack 222, supply to be fixed in the inside of described shell 1 with plugging of above-mentioned pin 13, be provided with an open-work 223 in contiguous described jack 222 places in addition, use spacing in the groove 212 that convexedly stretches in described core 21 for plugging of a dowel 224, described core 21 one ends have a dead bolt 211, it is the rotation that plugs for a key, uses the operation that the open and close lock is provided;
Described tumbler 3, it is to be a ducted body, and it is inner, and the one end has a microscler open-work 31 for installing a spring 5, and for described dead bolt 211 sheathed interlocks, its periphery two sides respectively are provided with a grooving 32;
Described base 4, the center has a trepanning 41, sheathed lock knot for a locking bar 7, the one end is to be sheathed in the described tumbler 3, the periphery of the other end has a jack 42, for plugging of above-mentioned pin 13, makes it be fixed in described shell 1 inside, described base 4 be provided with the corresponding circular holes 43 of the grooving 32 of described tumbler 3 for the installing of steel balls 44, described steel ball 44 upper and lower moving are convexedly stretched in described trepanning 41 and the described grooving 32;
By above-mentioned member, when the operation desiring to lock, be that described locking bar 6 is sheathed in the described trepanning 41, rotating described core 21 again makes dead bolt 211 rotations of one end drive described tumbler 3, the steel ball 44 that convexedly stretches in described grooving 32 is forced in the described trepanning 41 and is arranged in the card ditch 71 of described locking bar 7 ends, make its state that is a locking (as shown in Figure 4); Again when the operation desiring to unblank, be to rotate described core 21 by a key 8, make described dead bolt 211 rotations drive described tumbler 3, make described grooving 32 lucky positions corresponding to described steel ball 44, again described locking bar 7 is outwards extracted out, described steel ball 44 was subjected to the compressing of described locking bar 7 and toward the displacement of the direction of described grooving 32 and then break away from described card ditch 71, so can easily described locking bar 7 be extracted out, and finish the operation of unblanking (as shown in Figure 5) this moment; Because an end of described tumbler 3 is to fit in described lock body 2, the other end is to be resisted against described base 4, and described lock body 2 and base 4 are to be fixed in described shell 1, and the gap that is shifted between each member of spring 5 available buffers that described tumbler 3 inside install, so be the state that is a location between its member, can not produce any spacing, effectively prevent the situation become flexible, also can not take place to lose efficacy because of displacement causes anti-theft feature even knock with bigger external force.
