Description of the Invention: [Technical Field] The present invention relates to a combination lock with a positioning structure, and refers to a combination lock installed in a lock to present a locked or unlocked state of the brake lock as a whole. [Prior Art] Ο 役 码 code lock is a common brake structure installed in the lock, please refer to the prior art Zhao code lock (4〇〇) shown in the eighth figure, which comprises a casing (4〇), An inner brake assembly (50), a plurality of outer dial rings (6〇) and a stop piece (7〇), the inner brake assembly (50) is disposed in each outer dial ring (6〇), and the user rotates The outer dial (6〇) changes the relative positional relationship between the outer dial (60) and the inner brake assembly (5〇), thereby changing the state in which the combination lock (400) is locked or unlocked as a whole. The stop piece (70) is disposed in the casing (4〇) and adjacent to each outer ring (6〇), and a plurality of elastic pieces (71) are extended and formed on the stopper piece (7〇), and each piece of the piece (4) 71) adjacent to the opposite outer dial _, each outer ring (10)) has a plurality of grooves (61) spaced apart on the outer circumference of the outer ring (6) on the outer surface of the outer ring (6 〇). Between the slots (61), there is a pattern for marking (for example, a number or a text when the outer dial (60) is rotated.] By the single-groove (61) and the elastic piece (the same as the spring), The dial (60) is positioned to display the corresponding password. However, the prior art combination lock has the following disadvantages: 1. The spring (7) of the stop piece (70) continues to be with the outer dial (6〇). The outer wall surface is rubbed, so that the outer dial (10) can be positioned by the frictional force, except that the outer piece (60) can be positioned when the elastic piece (71) is engaged with the groove (61), and the outer ring (10) can be positioned. Relative to the angle of the password, it will be difficult for the user to infer that the outer dial is just moved to the correct position, which is disadvantageous for the user to rotationally position the outer dial (60) to a specific position. 3 201040370 2. The outer surface of the outer ring (60) except the groove (61) is generally flat. When the user uses the finger to move the outer ring (60), the groove (61) itself is inconvenient. As the point of application at the time of the shifting, the rest of the flat portion is also inconvenient for the user to apply force, so the outer dial ring in the prior art is not convenient for the user to move. 3. When assembling the stop piece (70), each spring piece (71) needs to accurately correspond to each outer ring (60), which increases the burden on the process and improves the overall manufacturing cost. SUMMARY OF THE INVENTION In view of the above-mentioned shortcomings of the prior art, the present invention designs a combination lock with a positioning structure to improve the accuracy of the outer dial ringing, and also improve the positioning effect of the outer dial and simplify Process to reduce costs. In order to achieve the above object, the technical means adopted by the present invention is to design a combination lock with a positioning structure, comprising: a body comprising a top case and a bottom case, the top case being formed with a plurality of perforations The bottom case is concavely formed with a plurality of pockets, and a bottom piece is disposed on the bottom surface of each of the pockets, each of the elastic pieces has two ends and a central portion; and a plurality of outer dials are disposed on the casing t, Each outer ring is disposed in a corresponding one of the top shells, and each of the outer dials is disposed in the corresponding two slots of the bottom 35, and each of the outer dials and the corresponding elastic piece are convex. The outer portion of each outer ring is formed with a plurality of axial ribs on the outer surface of the outer ring. The adjacent ribs are adjacent to each other; the inner brake assembly is disposed in the casing and is disposed outside the outer casing. In the dial. 4 201040370: When the outer ring is rotated, the outer surface of the outer ring is offset from the spring piece. If the pattern of the outer ring is recognized by the perforation of the top case, the outer ring is rotated to drive the inner brake assembly. (4) Presenting the unlocked state. The advantages of the head and the present invention are as follows: 1. Since each of the ribs protrudes from the outer surface of the outer sprocket so that the % rotation causes the rib to abut against the central convex portion of the elastic piece, the elastic piece is contracted to accumulate the elastic force' When the user removes the force, the elastic piece returns to the rib of the outer outer ring under the action of the elastic force to force the outer dial to rotate by itself, and the outer dial continues to rotate to the corresponding area of the outer dial ring corresponding to the convex portion of the outer ring The center projection is engaged between the two adjacent ribs, so that the outer dial is stably positioned at predetermined angles even when the user's rotation is not complete.疋2. By using the ribs provided on the outer surface of the outer plucking ring, the user can directly apply the force on the rib to rotate the outer lap, thereby increasing the convenience and accuracy when the user rotates the outer lap. . 3. If the shrapnel is integrally formed on the bottom case, the assembly process is completely saved; even if the shrapnel and the bottom case are not integrally formed, each shrapnel is only correspondingly mounted in the groove, so the assembly only needs to be - The fact that the shrapnel is stuck in the groove can eliminate the need to align with the outer dial, and the above-mentioned methods can effectively simplify the process. Therefore, the present invention does have its practicality. [Embodiment] Hereinafter, the technical means adopted by the present invention for achieving the intended purpose of the invention will be further described in conjunction with the drawings and preferred embodiments of the invention. 201040370 Please refer to the first and second figures of the present invention in combination with a lock (丨00) incorporated in a cabinet lock. The present invention comprises a housing (10), a plurality of outer dials (20), and an inner brake assembly ( 30). Referring to the second to fourth figures, the foregoing housing (10) includes an opposite top case (11) and a bottom case (12), and a plurality of perforations (111) are formed through the top case (11). The bottom shell (12) is concavely formed with a plurality of pockets (121), each pocket (121) corresponding to a perforation (111) of a top shell (11), and the bottom surface of each pocket (121) is disposed There is a shrapnel (122) 'each shrapnel (122) has two end portions (123) and a central convex portion (丨24), and the central convex portion (124) is subjected to its own elastic force, so that it is opposite to the two ends (123). The slightly raised 'end ends' (123) are in contact with the inner wall surface of the bottom case (12). Please refer to the fifth figure. The elastic piece (122) can be integrally formed on the bottom case (12). The end portions (123) of the (122) are respectively formed on the inner wall surface of the bottom case (12). Please refer to the seventh figure, the elastic piece (122) can be locked in the pocket (121), and the elastic piece (122) The end portion abuts against the inner wall surface of the bottom case (12). Please refer to the second and fourth figures. The outer ring (2〇) is installed in the casing (1〇). The corresponding one of the outer ring (20) is inserted through the top casing (11). And the outer ring (20) of each of the perforating turns (111) is disposed in the corresponding groove (121) of the bottom case (12) and corresponds to the central protrusion of the corresponding elastic piece (122) (124) Abutting each other, the outer surface of each outer ring (20) is extended to form a plurality of axial ribs (21). When the outer ring (2 turns) is rotated, the user can directly apply force to the ribs ( 2 J) On the outer surface of each outer dial (20), located between adjacent ribs (21) is a pattern area (22). The pattern area (22) is provided with a pattern for marking (for example, numbers). Or text) for user identification, the user can identify the different pattern regions (22) that are rotated to different angles by the perforation (Π1) of the top case (11). The inner brake assembly (30) is disposed in the housing (1) and is disposed in the outer 6 201040370 dial (20). The inner brake assembly (3) generally includes a plurality of inner collars and a The central locking lever and the inner brake assembly (3〇) are used to interact with the outer dial (2〇) to lock or unlock the whole body. The specific structure of the inner brake assembly (3〇) is the technical field. The usual knowledge in it, so I won't go into details here. Referring to the fifth figure, when the outer dial (20) is rotated such that the pattern area (22) abuts against the central convex portion (124) of the elastic piece (122), the central convex portion (124) is just engaged with the two phases. Between the adjacent ribs (21), the outer dial (2〇) is positioned. When the positioning state is to be released, the user needs to apply a large force to push the rib (21) to the top and compress. The central projection (124), in turn, resists the spring force generated by the spring (122) to change the position of each of the pattern regions (22) of the outer dial (20). Referring to the sixth figure, when the user turns the outer dial (2 turns) but the pattern area (22) does not abut against the central convex portion (124) of the elastic piece (122), based on the convex rib (21) In the pattern area (22), it is convex, so that the rib (21) abuts against the central protrusion (124). At this time, the rib (21) compresses the central protrusion (124) to cause the elastic piece (η?) to accumulate. For the elastic force, the relative positional relationship between the outer ring (20) and the elastic piece (122) is unstable due to the elastic force, even if the user no longer applies the force to rotate the outer ring (20) in the elastic piece ( Under the action of the elastic force of 122), the outward dialing % (20) can still be forced to rotate until the central convex portion (124) is in a state of being firmly fixed under the state in which the adjacent convex portion (124) is engaged with the adjacent pattern region. The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and In general, the equivalents of the technical solutions of the present invention may be made without departing from the technical scope of the present invention, without departing from the scope of the present invention. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
