Specific embodiment

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can To be mutually combined.Below with reference to the accompanying drawings and in conjunction with the embodiments describing the utility model in detail.

As shown in Figure 1 and Figure 4, the tapered end of the present embodiment, including lock core 1 and lock tube 3, the center of lock core 1 is provided with key hole 11, intermediate sleeve 2 is arranged between lock core 1 and lock tube 3, coordinate between lock core 1 and intermediate sleeve 2 and be provided with multiple first lock assemblies 41 And a limit assembly 42, coordinate between intermediate sleeve 2 and lock tube 3 and be provided with multiple second lock assemblies 43.Multiple first locking groups Part 41 arranges that limit assembly 42 is located at the lower section of multiple first lock assemblies 41, for limiting along the depth direction of key hole 11 Insertion depth of the key processed 6 in key hole 11.Between between multiple first lock assemblies 41 and multiple second lock assemblies 43 In predetermined angle, the present embodiment, predetermined angle is preferably set to 90 degree.Use is provided between lock core 1, intermediate sleeve 2 and lock tube 3 In the spacer pin 5 for limiting the relative rotational angle of intermediate sleeve 2 of lock core 1.

In the present embodiment, the first lock assembly 41, the second lock assembly 43 adopt and are combined and formed by spring, multiple pellets Spring marble combination, limit assembly 42 using combined by multiple pellets formed pellet combination.

The tapered end of the present embodiment has locking bit, the first solution lock-bit and the second solution lock-bit, realizes locking in locking bit, the One solution lock-bit realizes pre- unblock, finally realizes unlocking action in the second solution lock-bit, below in conjunction with the accompanying drawings works of the 1-6 to the present embodiment Make principle and the structure change in releasing process is described in detail.

In locking bit, tapered end is in the lock state, and lock core 1 and intermediate sleeve 2 are by multiple first lock assemblies 41 connection lock It is fixed, intermediate sleeve 2 and lock tube 3 by the connection locking of multiple second lock assemblies 43, now multiple first lock assemblies 41 with it is multiple Predetermined angle is spaced between second lock assembly 43, predetermined angle is preferably set to 90 degree in the present embodiment.

During unblock, as shown in Figure 1, 2, 3, the key hole 11 that key 6 is directed at lock core 1 is inserted after certain depth, due to The barrier effect of limit assembly 42, key 6 cannot be continued into, and now key 6 solves lock-bit in first, as shown in A points in Fig. 1 Position, the first lock assembly 41 changes length with the insertion of key 6, releases the locking to lock core 1 and intermediate sleeve 2 so that lock Core 1 can be rotated relative to intermediate sleeve 2, but intermediate sleeve 2 and lock tube 3 are locked together yet by the connection of the second lock assembly 43, it is impossible to Realize unlocking action.

Key 6 is rotated, band movable lock core 1 is rotated, due to the effect of spacer pin 5 so that key 6 turns to predetermined angle, this 90 degree are preferably set in embodiment, as shown in Figure 4,5, 6, when now A points and B points are on same straight line, the first lock assembly 41 are located at the part 41-1 of lock core 1, limit assembly 42 follows lock core 1 to turn to B points together located at the part of lock core 1, with second Lock assembly 43 splices, and combination forms a new, complete spring marble combination, now continues to be downwardly into key 6, spacing Component 42 is squeezed in the hole of the second lock assembly 43, while part 41-1 and second lock of first lock assembly located at lock core 1 Only component 43 change together length after engaging also with continuing into for key 6, locks together lock core 1 and intermediate sleeve 2, and Unlock state between intermediate sleeve 2 and lock tube 3, then tapered end enters the second solution lock-bit, now by rotating key 6, can drive Lock core 1 and intermediate sleeve 2 are rotated together relative to lock tube 3, so as to realize final unlocking action.

Conversely, lock and to extract the operating procedure of key 6 substantially opposite with the operating procedure of unblock, by door lock it is good after, general When key 6 turns to A points and B points in line, a tooth is outwards pulled out, then reversely turn 90 degrees, you can extract key 6.

The lock head structure of the present embodiment is simple, and by cleverly structure the design of twice unlocking program is realized, is unlocking Cheng Zhongxu completes twice unlocking program and could finally realize unblock, substantially increases the difficulty of skilled unlocking, improves safety Theftproof performance, and designed using purely mechanical structure, reliability is high, low cost, with wide market prospects.

What deserves to be explained is, the quantity of intermediate sleeve 2 may further reference the present embodiment identical principle and arrange according to actual needs More layers, so as to arrange more multiple tracks unlocking program, further improves anti-theft security performance.

On this basis, the present embodiment further provides a kind of safety lock, including lock housing, above-mentioned tapered end and lock pin, lock Head is installed in lock housing, and lock pin is arranged in the intermediate sleeve 2 of tapered end.Due to using above-mentioned tapered end, with its all advantage, because This will not be described here.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
