Abstract

The utility model relates to a digit changeable key, belonging to a small hardware lock. The utility model uses a butterfly-shaped and nut-shaped twisting handle; a step hole is arranged at the central point of the twisting handle; a long screw rod is inserted in the hole; two locating notches are arranged at the upper end of the wall of the hole; a spring, a locating block with a convex point clamping strip, a regulating twisting plate whose bottom surface is provided with a concave clamping slot, a barrier sheet, and a nut are orderly sheathed on the upper part of the long screw rod; four to nine tooth rings are sheathed on the lower part of the long screw rod, all tooth rings are mutually inserted in a concave and convex way, and six convex teeth evenly distributed are arranged at the outer edge of each tooth ring. A plurality of keys can be made by the convex tooth shape of each tooth ring through permutation and combination, and the utility model the characteristic of using one key to unlock a plurality of locks.

Description

Adjustable digital key

The utility model belongs to the hardware lockset kind.

Existing cylinder lock is made up of key and tapered end.Key has the rugged profile of tooth of convex-concave on a side, each key can only have a kind of profile of tooth, and a key can only be driven a lock.A people will have several locksets, just must need several keys.The people that lockset is many more, his key is also just many more so, and common people often have bunch of keys, are difficult to preserve, and are very inconvenient.

The purpose of this utility model is: a kind of adjustable digital key that utilizes a key can drive a plurality of locks is provided.

Technical measures of the present utility model are: adopt the handle of turning round of a wing nut shape, turning round the handle center has shoulder hole, is fitted with long bolt in the hole, and there are two locating notches the hole wall upper end; Long bolt top is set with spring successively, has the locating piece of spur card article, bottom surface to have the adjusting of recessed draw-in groove to turn round plate, catch and nut; Be set with four to nine gear rings in the stock bottom, the mutual convex-concave of two end faces of each gear ring is pegged graft, and the outer rim of each gear ring has six uniform double wedges.

Adjustable digital key of the present utility model, because four to nine gear rings are housed, six double wedges that length is different are arranged on each gear ring outer rim, by turning each gear ring, make double wedge permutation and combination on each gear ring become the profile of tooth of different keys, make a key can replace tens, have and omitted the good effect of a people with a big string key to a hundreds of key.

Drawing explanation and embodiment state as follows: 3 is to turn round handle among the figure, there is shoulder hole the center, be fitted with long bolt 9 in the hole, there are two locating notches the hole wall upper end, is set with spring 4 successively on long bolt 9 tops, has the locating piece 5 of spur card article, the adjusting that there is recessed draw-in groove the bottom surface to turn round plate 6, catch 7 and nut 8.Be set with four to nine gear rings 1 and 2 in the bottom of long bolt 9, the mutual convex-concave of two end faces of each gear ring is pegged graft, and the outer rim of each gear ring has six uniform double wedges.

Turn round handle 3 (seeing Fig. 2 and Fig. 3),, shoulder hole is arranged like wing nut, there are two locating notch A the hole wall upper end, turn round that handle 3 lower ends are extended a gear ring, the outer rim of this gear ring has six double wedges, and this gear ring also can plug as a part and the bottom surface convex-concave of turning round handle 3 separately.

The locating piece 5 (seeing Figure 12 and Figure 13) that the spur card article is arranged.Spur card article B is arranged above the locating piece 5, and there is through hole the center.

The bottom surface has the adjusting of recessed draw-in groove to turn round plate 6 (seeing Figure 10 and Figure 11).There is recessed draw-in groove C the bottom surface of turning round plate 6 in adjusting, and recessed draw-in groove C and above-mentioned spur card article B (Figure 12) are symmetrical, reverse the location.

Catch 7 (seeing Fig. 8 and Fig. 9) and nut 8.Mainly be that plate 6 axial motions are turned round in the restriction adjusting.Figure 14 and Figure 15 are the schematic diagrames of long bolt 9, and the lower end is a hemispherical, and the upper end is a flat.

Be set with four to nine gear rings 1 and 2 in the bottom of long bolt 9; Gear ring (seeing Fig. 4 and Fig. 5) headed by 1 wherein, 2 are middle gear ring (seeing Fig. 6 and Fig. 7), two mutual convex-concaves of end of each gear ring are inserted and are pressed; Total number of gear ring can adopt four to nine, and six double wedges different in size are arranged on each gear ring outer rim.

Position shown in Figure 1 is each gear ring is fixing position, at this moment each gear ring and each gear ring with turn round handle 3 and fix, can not relatively rotate.Double wedge on each gear ring outer rim has been formed the key of six groups of dissimilar tooth forms; At this moment the applicable 1-6 of a key tapered end.Turn round plate 6 if reverse to regulate, to make and turn round the plate bottom surface and can fall into two locating notches turning round handle 3, to rotate gear ring 2 or 1 and rearrange combination, can produce the key that hexad can not profile of tooth again.So no matter how many tapered ends a people has, as long as remember the shaped as key bit that each tapered end is required, can allocate out and open tapered end one by one all.Here it is utilizes a key can open the goal of the invention of a plurality of tapered ends.Certainly it is not enough having only this key, also needs the lock core of existing cylinder lock is changed.With the keyhole of lock core (seeing Figure 16) by the radial six slotted eye shapes of changing into of in-line.

Claims
