[0009]

[Embodiment of device]

  First, the present invention will be described with reference to FIG. The present invention is designed to change the code of the conventional number lock. It is an improvement on the structure.   The shaft 2 includes a housing groove 21, a groove 25, a localization notch 212, a fixing hole 26, and a convex metal. 27 and.

[0010]   The packing 22 having the hole 221 and the tooth rod 222 is placed in the accommodation groove 21 and the tooth rod 2 The packing 22 is orientated by inserting 22 into the hole 213.

[0011]   After the pressing metal 23 having the hole 231 is put in the housing groove 21, the operation lid 24 is put in the housing groove 2. 1 to restrain the pressing metal 23, and to house the convex metal 241 located on the back wall of the operation lid 24. The operation lid 24 is orientated so as to align with the recessed notch 214 of the groove 21. 4 can't turn.

[0012]   2 to 6 show the structure of the assembled main body of the number lock, in which the pressing metal 23 When the tooth is not pressed, the convex tooth 41 of the tooth disc 4 is biased by the coil spring 6. It is locked in the engagement hole 33 of the number ring 3. 7 to 11 show the pressing metal 2 3 is the structure of the body of the numbered lock that is pressed, and the convex teeth 41 of the tooth plate 4 are At the same time as it is pressed by the pin 222 of No. 2 and separated from the engaging hole 33 of the number ring 3, The localization metal 232 of the pressing metal 23 passes through the localization notch 212 of the accommodation groove 21 and the accommodation groove 2 1 and the pin 222 of the packing 22 continues to Because the pusher 6 is pushed, the tooth plate 4 does not interlock with the number ring 3, and in this case the code is Can be changed.

[0013]   When the code change is completed, the orbital gold 23 2 disengages from the accommodation groove 21, and the localization gold 232 fits into the localization notch 212, so that The compression of the pin 222 of the packing 22 against the packing 22 is released, and the convex tooth 41 of the tooth plate 4 is It is biased by the coil spring 6 and again locked in the engagement hole 33 of the number ring 3. This Here, after inserting the tooth rod 71 of the male part 7 into the groove 25 of the shaft 2, the number ring 3 is turned. As a result, when the tooth disc 4 and the localization ring 5 are rotated in conjunction with each other, the male part 7 is changed to the female part 1. Can be locked in.

[0014]

[Effect of device]   With this structure, the use of numbered locks is easier and easier than the conventional ones. It can be operated quickly, and the code can be changed by simply pressing the code change structure with one hand. Can be changed.
