Abstract

The utility model relates to tapered ends of blade locks not moving in the same direction, which respectively consist of a lock body, a lock core, a clip key, a spring and blades, wherein the lock core is positioned in the lock body; every two blades are composited togehter in the forward and reverse directions, arranged at intervals in the shaft line direction of the lock core, and placed in the lock core, wherein one end of the blade is positioned by one spring and the other end thereof extends to the position of a key hole; every blade is provided with a keyslot, and the clip key is placed in a groove between the lock core and the lock body so as to lead the lock core not to rotate; in the lock core, a cylinderical key hole is arranged in the shaft line direction. As for the tapered ends of blade locks not moving in the same direction, when a plurality of built-in blades of the tapered ends are opened, every blade simutaneously moves respectively along the positive and reverse directions; the uncertain and contrary factors of the directions can completely withstand technical lock thieving and opening of various non-matching keys; and simutaneously, the cylindrical key hole in the lock core can prevent twisting and prying and lead the tapered ends to have ultrastrong anti-theft performance.

Description

The padlock head that non-same direction moves

Affiliated technical field

The utility model relates to a kind of daily mechanical lock, the padlock head that non-same direction moves.

Technical background

At present, mostly by in the key operated daily mechanical lock, the core component blade or the pellet shot from a slingshot of unblanking, all move to finish and unblank to unified direction, the moving direction that it is clear and definite, aspect so-called master key of prevention and technical pirate of the open lock, stayed great hidden danger, reduced the security performance of lock.

Summary of the invention

For solving the existing in prior technology problem, the padlock head that the utility model provides a kind of non-same direction to move, the built-in a plurality of blades of this tapered end are when unblanking, each blade moves respectively simultaneously to positive and negative both direction, the uncertainty of its direction and antagonism factor can be resisted the technical pirate of the open of all kinds of non-valid key fully and lock, simultaneously, cylindrical keyhole in the lock core can prevent to turn round sled, makes tapered end have superpower theftproof performance.

The technical scheme that its technical problem that solves the utility model adopts is: the padlock head that a kind of non-same direction moves, it comprises by lock body, lock core, the card key, spring and blade are formed, lock core is positioned at lock body, per two forward and reverse lumping together of blade, be spaced by the lock core axis direction, be placed in the lock core, end at blade is located with a spring, and the other end stretches to the keyhole position, all has keyway on each blade, the card key is placed in the groove between lock core and the lock body, make lock core not rotatable, in lock core, have cylindrical keyhole along axis direction, when unblanking, the cylindrical key of coupling promotes each blade and moves by positive and negative different direction initialization in being gone into by keyhole, coincide with pre-pits on the key, under the reaction of spring, make each keyway above blade be same linear state below the card key, the card key then falls in the lock core, simultaneously on the keyway position fully, screw key, lock promptly is opened.

Described each blade is except that the difference of keyway position, and size is identical, moulding is consistent, and the placement direction in lock core can change.

Blade quantity in the described lock core, can several be set according to the size and the safety requirements of tapered end, place respectively by forward and reverse variation, for making effective utilization in the compact more firm and space of lock core, can two forward and reverse lumping together of blade be spaced, also can be spaced by individual blade, its effect and effect are the same.

Described card key is shaped as cuboid, and its height is greater than the lock body groove height, the total length that length should be arranged greater than the blade in the lock core, and less than lock core length.

Described cylindrical keyhole is positioned at the edge of lock core external diameter, with identical between lock core axis side.

The specific embodiment

Shown in Figure 1, the padlock head that a kind of non-same direction moves, it comprises by lock body 1, lock core 2, blade 3, blade 7, card key 4, card key spring 5, leaf spring 6 is formed, lock core 2 is positioned at lock body 1, blade 3 is stuck on the lock core 2, have keyway 10 on the blade 3, the one end is located with a spring 6, and the other end stretches to keyhole 8 positions, blade 7 is in the inner of blade 3, but the direction of placing opposite (as shown in Figure 3), card key 4 are placed in the groove between lock core 2 and the lock body 1, the adjacent spring 5 that is placed with in top, be used to increase thrust, card key 4 is between lock core 2 and lock body 1, and it is expressed as lockup state, otherwise, when each blade 3 and the keyway above the blade 7 10, be same linear state below card key 4, card key 4 falls in the lock core 2 fully, is unlocking condition (as shown in Figure 4).

Shown in Figure 2, blade 3 and blade 7 lump together, oppositely place (as shown in Figure 3), purpose is to allow effective utilization in the compact more firm and space of lock core 2, the any special measures that reverse effect is antitheft just, blade 3 and blade 7 also can be with under lock core 2 cooperate, single being spaced, the orientation arbitrarily is set, its effect is the same, and cylindrical keyhole 8 is positioned at the edge of lock core 2 external diameters, with identical between lock core axis 9 sides, card key 4 is placed in the groove between lock core 2 and the lock body 1, wherein the groove in the lock body 1 up and down the degree of depth less than the height up and down of card key 4, to strengthen the tapered end safety, the left and right sides length of card key 4, greater than whole total lengths of the arrangement of blades 3 and blade 7, and less than the length of lock core 2.
