Description
Technical field
The utility model relates to a kind of tapered end, particularly a kind of double circular tapered end.
Background technology
Tapered end of the prior art generally all only is provided with row's lock pin, and in order to improve theftproof performance, people are provided with two row's lock pins, existing two arrange the tapered end of detent configuration, generally adopt the key of flat structure, open for convenience, can only adopt two row's lock pins of symmetrical structure, its theftproof performance descends to some extent; If two row's detent configuration are asymmetric, when opening lock, key must be aimed at the relevant position of fore shaft, could insert unlatching, and because of key has directionality, it is not very convenient using.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of theftproof performance double circular tapered end good and easy to use.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of double circular tapered end, comprise the tapered end shell, be arranged at the lock core in the tapered end shell rotationally, described tapered end shell is provided with two row's lockpin holes, two row place, lockpin hole center at grade intersections are angled, described lock core be provided with the tapered end shell on two row lockpin holes corresponding two row step through-holes, the lock pin spring of packing into successively in lockpin hole and the corresponding step through-hole, the interior lock pin of outer lock pin and band boss, on the tapered end shell two row lockpin holes between the middle position be provided with pin hole, lock core be provided with the tapered end shell on the corresponding bayonet lock step through-hole of pin hole, the bayonet lock spring of packing into successively in pin hole and the bayonet lock step through-hole, the rotation bayonet lock of positioning bead and band boss, the center of lock core is provided with the cylindrical key jack.
The beneficial effect of the double circular tapered end of the utility model is: because the center of lock core is provided with the cylindrical key jack, can adopt the key of cylindrical structure, when inserting key operated lock, there is not directionality, therefore extremely easy to use, especially under the environment of dark, old man and children use more convenient; Because key does not have directionality, two row's lock pins can be provided with arbitrarily, have therefore improved theftproof performance greatly.
The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 2 is a general structure schematic diagram after the assembling of double circular tapered end among Fig. 1;
Fig. 3 is the A-C sectional view among Fig. 2;
Fig. 4 is the B-C sectional view among Fig. 2.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of embodiment of the double circular tapered end of the utility model, comprise tapered end shell 14, be arranged at the lock core 6 in the tapered end shell 14 rotationally, described tapered end shell 14 is provided with two row's lockpin holes, two row place, lockpin hole center at grade intersections are angled, described lock core 6 be provided with tapered end shell 14 on two row lockpin holes corresponding two row step through-holes, the lock pin spring 8 of packing into successively in lockpin hole and the corresponding step through-hole, the interior lock pin 10 of outer lock pin 9 and band boss, on the tapered end shell 14 two row lockpin holes between the middle position be provided with pin hole, lock core 6 be provided with tapered end shell 14 on the corresponding bayonet lock step through-hole of pin hole, the bayonet lock spring 11 of packing into successively in pin hole and the bayonet lock step through-hole, the rotation bayonet lock 13 of positioning bead 12 and band boss, the center of lock core 6 is provided with cylindrical key jack 16.Reasonable more and compact for the structure that makes tapered end, described two row place, lockpin hole center at grade intersections become 90 degree angles.For the structure that makes tapered end more attractive in appearance, the end of described tapered end shell 14 is provided with tapered end cover 2, tapered end cover 2 entangles the head of lock core 6, the head cavity of lock core 6 is provided with to insert and hacks seat 3, insert and to hack seat 3 and be provided with chute, insert the chute that hacks seat 3 and be provided with two and insert and hack 4, each insert hack 4 and the inwall of lock core 6 between be provided with rectangle spring 5, owing to be provided with tapered end cover 3 in the end of tapered end shell 10, improved the performance attractive in appearance of tapered end greatly; And hack 4 owing between tapered end cover 2 and lock core 6, be provided with to insert, when extracting key, to insert and hack 4 and under rectangle spring 5 acts on, close, to seal the cylindrical key jack 16 of lock core 6, can prevent effectively that foreign material from falling in the key hole 16.
The operating principle of the double circular tapered end of the utility model is: as Fig. 3, shown in Figure 4, when opening lock, key can insert in the cylindrical key jack 16 at lock core 6 centers directionlessly, when key 1 arrives the relevant position, rotation bayonet lock 13 in the lock core 6 is under the effect of bayonet lock spring 11, snap in the groove that key end is provided with, separately interior lock pin 10 in two row's step through-holes that the two row's concave point pushing tow lock cores 6 that are provided with on the key are provided with, outer lock pin 9 and lock pin spring 8, the top of the interior lock pin 10 of two rows of different length is aligned, this moment can rotational lock core 6, lock core 6 drives thumb wheel 15 and rotates, and reaches the action that undoes the lock.
