Abstract

The utility model discloses a marble free rotating lock-head, which comprises a lock shell and a lock core with a key hole. A round sleeve is positioned between the lock shell and the lock core that is provided with a row of I-shaped marbles, at the end of which a reset spring is positioned. One side of the lock core is provided with T-shaped press marbles that are perpendicular to the H-shaped marbles. A round shell outside the T-shaped press marbles is provided with a press spring, and the round sleeve has a locking square groove, between the locking square groove and a locking semicircular groove in the lock shell, a locking latch is positioned. This set of mechanical structure makes the lock core in a state of free rotating when unmatched keys are used to unlock the lock head, which makes the violent unlocking method of breaking the inner structure of the lock core useless, enhances the theft-proof function of the lock, simplifies product structure, and lowers the cost.

Description

A kind of marble idle rotation lock head
Technical field
The utility model relates to a kind of tapered end, and is especially relevant with a kind of marble idle rotation lock head.
Background technology
At present, the lock pin lock that many kinds are arranged on the market, general lock, the direct interlock unlocking mechanism of lock core, become possibility thereby make the violence damage lock core reach the purpose of unblanking, in order to realize the purpose of safe antitheft, lock production is competitively adopted complicated technology, expectation improves the safety factor of lock, also makes the cost of production of lock improve many.
Summary of the invention
The purpose of this utility model provides a kind of marble idle rotation lock head, and this tapered end is provided with one group of frame for movement, can strengthen the theftproof performance of lockset, has simplified product structure simultaneously, has also reduced cost of production.
The technical solution adopted in the utility model is to achieve these goals: a kind of marble idle rotation lock head, comprise lock housing, lock core, on lock core, offer the key hole, between lock housing and lock core, be provided with circular sleeve, on lock core, be provided with row's I shape hoodle, I shape hoodle rear end is provided with back-moving spring, side at lock core is provided with the T type decorative pearl on top of an official cap, the T type decorative pearl on top of an official cap is vertical with the I shape hoodle, at the sheathed top of T type decorative pearl on top of an official cap cylindrical spring, offers the locking square groove on circular sleeve, offer the locking half slot in lock housing, between locking square groove and locking half slot, be provided with the locking bolt.
When non-valid key attempted to open tapered end, lock core self was in sky and revolves state, can 360 degree rotate but interlock unlocking mechanism not, therefore can effectively prevent violence damage tapered end internal construction, reach antitheft effect.
Description of drawings
Fig. 1 is the utility model marble idle rotation lock head lock-out state cross sectional representation;
Fig. 2 is the utility model marble idle rotation lock head opening cross sectional representation.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.As Fig. 1, shown in Figure 2, the utility model relates to a kind of marble idle rotation lock head, comprise lock housing 1, lock core 2, on lock core 2, offer key hole 6, between lock housing 1 and lock core 2, be provided with circular sleeve 3, be provided with row's I shape hoodle 5 on lock core 2, I shape hoodle 5 rear ends are provided with back-moving spring 7, are provided with the T type decorative pearl on top of an official cap 9 in a side of lock core 2, the T type decorative pearl on top of an official cap 9 is vertical with I shape hoodle 5, end that the T type decorative pearl on top of an official cap 9 protrudes and I shape hoodle 5 I-shaped grooves coupling are coincide, and at the sheathed top of T type decorative pearl on top of an official cap cylindrical spring 8, offer locking square groove 10 at circular sleeve 3, offer locking half slot 11 in lock housing 1, between locking square groove 10 and locking half slot 11, be provided with locking bolt 4, circular sleeve 3 and lock housing 1, lock core 2 is one group of concentric structure, and lock core 1 can freely rotate by 360 degree, circular sleeve 3 also can rotate, circular sleeve 3 interlock unlocking mechanisms.
During use, as Fig. 1, when non-key inserts month type keyhole 6, the T type decorative pearl on top of an official cap 9 projections can not eject the I-shaped groove that embeds on the I shape hoodle 5, and locking bolt 4 is in the locking half slot 11, and lock housing 1 forms the buckle state with circular sleeve 3, and lock core 2 is separated from each other with circular sleeve 3, lock core 2 self under external force can free empty three-sixth turn, rotates but do not drive circular sleeve 3, so can't open tapered end by the interlock unlocking mechanism.
As Fig. 2, when the key of coupling inserts keyhole 6, I shape hoodle 5 inwardly pushes, the T type decorative pearl on top of an official cap 9 projections eject in the I-shaped groove that embeds I shape hoodle 5, at this moment lock bolt 4 and separate with locking half slot 11 in the lock housing 1, and lock core 2 is in the buckle state with 3 of circular sleeves, this moment rotational lock core 2, just can drive circular sleeve 3 and rotate, circular sleeve 3 interlock unlocking mechanisms reach the purpose of unblanking.
Adopt the tapered end of this structure, the method for unlocking that destroys the lock core internal construction that can use force lost efficacy, and strengthened the theftproof performance of lockset, had simplified product structure simultaneously, had also reduced cost of production.
