Abstract

The utility model relates to a cipher lock for cases, which is used for traveling cases and suitcases. The cipher lock comprises a plurality of sets of cipher rings 1 which are composed of cipher inner rings 11 and cipher outer rings 12. The utility model is characterized in that each cipher ring 1 is arranged on a lock axle 3 passing through an inner box 2 and conducting axial movement. Each set of cipher rings are arranged in a blank lattice of the inner box in a lattice shape. The end part of one end of the lock axle is provided with an L-shaped convex part 31 and a spring 4 is arranged on the part positioned among two convex parts and the inner box. Outer edges of the two convex parts convexly extend to the outer part of a case body 5 used for installing the inner box and the lock axle. The utility model realizes that the cipher changing operation can be conducted without opening the case to enable the cipher changing operation to be more convenient and rapid.

Description

The case coded lock

The utility model relates to a kind of coded lock, particularly relates to a kind of case coded lock that can be used on various suitcases and the suitcase.

The common coded lock of people is used on suitcase or the suitcase more, and this class coded lock generally all is made up of three left and right sides degrees wheels, adopts the embedded joint portion of case lid up and down that is installed in.Because the existing password lock is except that degrees wheel, other parts all place in the casing, therefore when setting or revise password, could set therefore operation inconvenience after all needing to unpack.

The purpose of this utility model is to provide a kind of need not unpacking can carry out the Change Password operation, makes the case coded lock of Change Password faster and more convenient operation.

For achieving the above object, the utility model provides a kind of case coded lock, this coded lock comprises the password circle 1 that many groups mainly are made of password inner ring 11 and password outer ring 12, it is characterized in that, described password circle 1 is contained in and runs through inner box 2 and can do on the axially movable lock shaft 3, every group of password circle places in the space of trellis inner box, lock shaft one end end is provided with one L shaped protruding 31, convexedly stretch in the outer rim that spring 4, two projectioies are housed between two projectioies and the inner box on it and install outside the casing 5 that inner box and lock shaft use.

Multiple cipher inner ring 11 has different diameter of bores, the diameter of bore of every group of password inner ring is corresponding with the diameter of axle of lock shaft 3, each endoporus inner edge all is provided with a keyway, and the inner ring external surface is interval with a plurality of radial projection 111, also is provided with an axial projection 112 on the one end face.

Described lock shaft 3 is the scalariform axle, one end end be provided with by dual U-shaped plate sealing be formed by connecting L shaped protruding 31, this protruding vertical edge 311 is stretched out by casing 5 tops, 312 of its horizontal sides are stretched out by the casing sidepiece; This lock shaft is divided into and the corresponding plurality of sections of password circle internal diameter, and each section diameter dwindles to the other end gradually from an end that is provided with projection 31.

All have on every block of lattice plate of described inner box 2 with the diameter of axle of lock shaft 3 accordingly with the axis hole of keyway.

The inner edge of described password outer ring 12 is provided with the radial projection 111 corresponding grooves 121 with password inner ring external surface.

According to technique scheme, the utility model is owing to be provided with sponson on lock shaft, this part is exposed to outside the used casing, therefore need not to unpack by its people can be easily, very promptly carry out the operation of Change Password, this brings great convenience with regard to the user for suitcase or suitcase.The utility model also has simple in structure, and volume is little, characteristics such as reliable operation.

The utility model is described in further detail below in conjunction with drawings and Examples.

Consult Fig. 1, Fig. 2, Fig. 6, case of the present utility model has a casing 5 with coded lock, the casing upper articulation has a loam cake 51, the inner box 2 that the fixed password circle is used is housed in the casing of loam cake bottom, its structure as shown in Figure 5, it is trellis, all has the axis hole 21 of the different band keyway of diameter on every block of lattice plate, is used to support lock shaft 3.Inner box is divided into three lattice in this example, the password circle 1 of packing in every lattice, its structure as shown in Figure 3, every group of password circle all mainly is made of password inner ring 11 and password outer ring 12, wherein password inner ring 11 has different diameter of bores, and the diameter of bore of every group of password inner ring is corresponding with the diameter of axle of lock shaft 3, and each endoporus inner edge all is provided with a keyway, and the inner ring external surface is interval with a plurality of radial projection 111, also is provided with an axial projection 112 on the one end face.The periphery of password outer ring 12 is marked with scale, and its inner rim is provided with the radial projection 111 corresponding grooves 121 with password inner ring external surface.Password inner ring and spring 113, pad 114 are one to be assembled in the password outer ring, and the radial projection 111 of password inner ring external surface is inserted in the groove 121 on the inner edges of password outer ring, and both are fused.Above-mentioned three groups of password circles are contained on the lock shaft 3, the lock shaft structure as shown in Figure 4, this lock shaft is the scalariform axle, it runs through inner box 2 and is supported on the axis hole 21 on the inner box lattice plate, one end end be provided with by dual U-shaped plate sealing be formed by connecting L shaped protruding 31, this protruding vertical edge 311 is stretched out by casing 5 tops, and 312 of its horizontal sides are stretched out by the casing sidepiece.This lock shaft is divided into password circle internal diameter corresponding three sections, each section diameter is corresponding with password inner ring internal diameter, its diameter dwindles to the other end gradually from an end that is provided with projection 31, all is provided with an axial bond shape projection 32 on the external surface of every section axle, in the keyway on this projection insertion password inner ring.The spring 4 that makes lock shaft reset usefulness is housed between two projectioies and inner box on the lock shaft.This lock shaft can move axially.

Use of the present utility model and duty such as Fig. 6, shown in Figure 7 when to good password, make the radial projection 111 of password inner ring external surface align keyway on the axis hole 21 on the inner box 2, just can inwardly promote lock shaft, lock are opened (Fig. 7 is unlocking condition).When the needs Change Password, can earlier lock be opened, inwardly push away lock shaft (direction shown in arrow among Fig. 6) then to inner end, make that the radial projection 111 on the password inner ring is separated with groove 121 on the inner edge of password outer ring, this moment can the new password of any conversion.
