Description

The present invention relates to a dual-purpose number lock. In particular, even if the user forgets the set code at a time, a spare lock and a probe provided on the female tablet can search the set code again. It relates to a number matching lock.

General numbering locks are used for suitcases and the like, and there are dozens of structures as numbering locks connected to wires, but general numbering locks that can convert numbers are shown in FIG. The number matching lock capable of changing the number is provided with a male lock body 90 provided with an insertion rod 902 having a plurality of locking teeth 901 and a through hole 911, and a plurality of planes and A plurality of numbered rings 91 having locking holes formed between the respective protruding teeth 912 and an annular body provided with a cutout 921 are provided at equal distances. A plurality of toothed rings 92 provided, a notch 931 is provided, one elastic element 932 is attached, a plurality of positioning rings 93 having an annular shape, a spring 94, a core having a groove 951 and a projection 952. And an axis 95.

After assembling the toothed ring 92 into the number ring 91, the core shaft 95 is inserted into the toothed ring 92 and the number ring 91, and a pin 96 is inserted into the through hole of the female tablet body 97 and the fixing hole 971 of the core shaft 95. Is completed, the assembly work is completed.

The core shaft 95 is provided with a receiving groove 953, the receiving groove 953 receives a packing 954 having a through hole 9541 and a pin 9542, and a pressing metal 955 having a through hole 9551 and a positioning projection 9552, and They are closed by one closing ring 956. The closing ring 956 is engaged with a notch 9531 provided in the accommodation groove 953 by a projection 9561 and positioned.

With the above-described configuration, the pin 9542 provided on the packing by pressing the pressing metal 955 is brought into contact with the toothed ring 92, so that the protruding teeth 922 of the toothed ring 92 are detached from the locking holes of the number ring 91, At this time, since the number ring 91 is not linked with the toothed ring 92, the code can be changed by turning the number ring 91.

The above-mentioned number matching lock can change the set encryption, but if the user forgets the encryption set, the number matching lock cannot be opened unless the number matching lock is destroyed. Can no longer be used.

An object of the present invention is to provide a dual-purpose number matching lock in which even if a user forgets a setting code at a time, the setting code can be searched for again by a spare tablet and a probe provided on the female tablet.

In order to achieve the above object, the invention of the present application is that a male shaft provided with locking teeth is provided with a core shaft, and the core shaft has a number ring, a toothed ring, and a localization ring. , A number ring set comprising an elastic element is fitted and provided, and the toothed ring and the localization ring are separately provided with cutouts at positions corresponding to the locking teeth of the male tablet, Further, after assembling a spring and a closure ring into a female tablet, when they are fitted to the core shaft, the male tablet and the female tablet can be combined with each other. A spare lock body is provided on the body, and the spare lock body is locked and locked in a restriction groove of a core shaft provided to be fitted in the male lock body of the number matching lock, whereby the spare lock body is locked. A groove provided in the spare lock by the restriction groove of the core shaft when turning. Since the corresponding lock groove and the restriction groove provided in the core shaft are not locked to each other, the male tablet and the core shaft can escape from the female tablet, so that the locked object is not locked. The gist of the present invention is a dual-purpose number-matching lock characterized by being released from a wire connected to the number-matching lock.

In the invention of the present application, a probe is provided, and after the male tablet body escapes from the female tablet body, the probe is inserted into a notch provided in a closing ring, and a toothed ring and a localization ring in a number ring set are inserted. While turning, the position of the notch provided in the toothed ring and the localization ring is detected, and when passing through a plurality of number rings, the correct setting code can be searched back, so that the number matching lock can be used again. The gist is that the lock is a dual use number combination lock according to claim 1.

According to the dual use number matching lock according to the present invention, if the user forgets the setting code, the number matching lock can be released by turning the spare lock provided on the female tablet, so that as an emergency measure, Very convenient.

Further, according to the dual use number matching lock according to the present invention, the released number matching lock can search for the encryption set by the probe, so that the double use number matching lock can be used again. . Very economical.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, reference is made to FIGS. FIG. 1 is an exploded perspective view of the dual use number lock according to the present invention, and FIG. 2 is a sectional view of the assembled dual use number lock according to the present invention. The numbered lock 1 has a male shaft 10 mainly provided with locking teeth 101, a core shaft 20 is provided, and a bottom limit end of the core shaft 20 is provided with one limiting groove 201; , A number ring set 30 including a toothed ring 302, a localization ring 303, and an elastic element 304 are provided in a plurality of fittings on the core shaft 20, and a male lock of the toothed ring 302 and the localization ring 303 is provided. Notches 3021 and 3031 are provided at positions corresponding to the locking teeth 101 provided on the body 10, and after the spring 40 and the closing ring 50 are assembled to the female tablet body 60, they are attached to the core shaft 20. When fitted, the male tablet 10 and the female tablet 60 can be assembled.

FIG. 3 is also referred to. FIG. 3 is a cross-sectional view illustrating the use state of the dual-purpose number lock according to the present invention. The female tablet body 60 is provided with a spare lock body 70. The spare lock body 70 is locked and locked in the restriction groove 201 of the core shaft 20 which is fitted into the male lock body 10 of the number matching lock 1. Thus, the male tablet 10 and the female tablet 60 can be locked with each other. If the user forgets the set code, the preliminary lock 70 is turned, so that the restricting groove 201 of the core shaft 20 corresponds to the groove 701 provided in the preliminary lock 70. 70 and the restricting groove 201 provided in the core shaft 20 are not locked with each other, so that the male lock body 10 and the core shaft 20 can escape from the female tablet body 60. It is released from the wire connected to the lock 1.

Next, reference is made to FIGS. FIG. 4 is a cross-sectional view illustrating an operation of retrieving the code of the dual use number combination lock according to the present invention, and FIG. 5 is a cross-sectional view of the dual use number combination lock according to the present invention. Further, a probe 80 is provided, and after the male tablet 10 escapes from the female tablet 60, the probe 80 is inserted into a notch 501 provided in the closing ring 50, and a toothed ring in the number ring set 30 is provided. The positions of the notches 3021 and 3031 provided in the toothed ring 302 and the localization ring 303 are detected while turning the localization ring 302 and the localization ring 303. Since the set number of the number ring 301 corresponds to the positions of the cutouts 3021 and 3031 of the toothed ring 302 and the localization ring 303, the probe 80 is inserted into the cutout 501 provided in the closing ring 50, and the number is set. While turning the toothed ring 302 and the localization ring 303 in the ring set 30, the positions of the cutouts 3021 and 3031 provided in the toothed ring 302 and the localization ring 303 can be detected. When the probe 80 passes through the cutouts 3021 and 3031 provided in the toothed ring 302 and the localization ring 303 in the plurality of number ring sets 30, the correct setting code can be searched back, so that the number lock 1 can be used again. Become like
