Abstract

The utility model provides an active type puzzle lock for motor cycle which belongs to the field of lockset, comprising a lock body and a U-shaped lock rod. The active type puzzle lock for motor cycle is used for motorcycles and power assist vehicles which can not be fixedly provided with locksets. The five-digit number cipher of the utility model comprises five plastic zinc composite dials. A tooth form movable lock rod is matched with the U-shaped lock rod in order to realize the opening and closing of the lockset. The number of each lock is different. The performance of the cipher is reliable. High-strength material is adopted by the lock body and the lock rod so that the lock is not easy to tong. The active type puzzle lock for motor cycle has the advantages of reliable anti-theft performance, easy use and free switching so long as remembering the cipher. The anti-theft performance of the utility model greatly exceeds the existing various theft-proof lock means.

Description

Movable motorcycle power assist vehicle coded lock

The utility model relates to the theftproof lock field, specifically a kind of movable motorcycle power assist vehicle coded lock.

Existing motorcycle power-assist lock has: ring lock, U-shape lock etc., because this class lock is all used key operated, ubiquity a key can drive several locks, or can both open these locks with master key, and it is not fastening firm, easily broken, pry open, so the theftproof performance of this class lock is relatively poor, make that joyriding is organic to be taken advantage of by pincers.

The purpose of this utility model is to provide a kind of lockset that can overcome unlocked by universal key easy to use at above-mentioned defective, and can prevent to prize the theftproof lock that tonger has good anti-theft effect.

The utility model is achieved through the following technical solutions: mould the compound number letter disk of zinc by five and form a five-digit number password, realize the open and close of lockset with mobile locking bar and cooperating of U-shape lock bar.This lock has lock body, the U-shape lock bar, profile of tooth moves three main partly compositions of locking bar, one sets of numbers letter disk is housed on the lock body, letter disk adopts ABS plastic and kirsite to be composited, the lock core of combination up and down is housed in the lock body, the lock core fixed cover of two zinc alloy diecastings is equipped with at the lock body two ends, having put two diameters is 12 millimeters holes, be used for the U-shape lock bar and move locking bar by hole, the garden inner profile of tooth of insertion lock body, profile of tooth moves locking bar, and two diameters to be arranged in making with 25 * 5 band steels be 12 millimeters the hole and the elongated slot of two 10 mm wides, when the U-shape lock bar inserts the hole, garden, under the situation of aiming at password, move locking bar with the hand propelled profile of tooth, dial random password then, U-shape lock bar and lock body have just pinned securely.As long as set password during unlatching correctly with promoting profile of tooth moves locking bar in the other direction, separate with lock body in 12 millimeters holes that the U-shape lock bar withdraws from the fixed cover.The U-shape lock bar is made with 14 millimeters square steel, and inserting lock body, partly to be processed into diameter be 12 millimeters knob, and fastening mobile locking bar, partly to be processed into diameter be 10 millimeters snap close.Two kinds of locking bars are all through Technology for Heating Processing, and intensity height, fastness are good, and its theftproof performance is considerably beyond existing various theftproof locks.

The utility model has the advantages that with moulding the compounded figure disc of zinc and form the five-digit number password that has nothing in common with each other, the password of each lock is had nothing in common with each other, has only a jack per line in 100,000 locks, cryptographic capabilities is reliable, easy to use, as long as remember password, switch can be avoided the loss of key lock key freely, latch fitting all adopts high-strength material to be difficult for the sled pincers, and reliable theftproof performance is arranged.This lock does not fixedly mount, and to various motorcycle, the power assist vehicles that can not fixedly mount lockset, it is convenient feasible to lock flexibly.

Concrete structure of the present utility model is provided by following examples and accompanying drawing:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 moves the Structure of lock rod schematic diagram for profile of tooth of the present utility model;

Accompanying drawing 3 is a user mode schematic diagram of the present utility model.

As shown in drawings: this lock comprises that the lock body (7) formed of lock core (4) and U-shape lock bar (1) profile of tooth move (2) three parts of locking bar and form up and down by moulding the compound letter disk of zinc (5) lock core fastening devices (6) lock core compressor arm (3).Mould the locating slot that the compound letter disk of zinc (5) makes ten five equilibriums, 36 degree according to the direction of locking plate at inner ring and print number arbitrarily, the numeral of each number and locking plate direction are had nothing in common with each other, composition is respectively locked different passwords, realizes that 100,000 locks have only a jack per line.Following lock core in the lock core (4) has and adorns five springs (12) in five die casting holes (11) and locate usefulness when moving as letter disk up and down.Profile of tooth moves locking bar (2) and is loaded on up and down between the lock core (4), and it is 12 millimeters hole, garden (9) that two ends have two diameters, the inboard elongated slot (10) that connects two 10 mm wides in hole, two gardens (9).U-shape sword iron (1) double-ended vehicle system diameter is 10 millimeters a snap close (13).In use lock body is adorned motorcycle front column (8) one ends, inserting profile of tooth with U-shape lock bar (1) towards lock body (7) direction at another root post moves in the hole, garden, two ends (9) in the locking bar (2), then profile of tooth is shifted mobile locking bar (2), two elongated slots (10) are pinned the cover of the snap close (13) in the U-shape lock bar (1), stir again and mould zinc letter disk (5), lock body (7) and U-shape lock bar (1) have just pinned like this, realize the antitheft purpose of the utility model.As long as pull out positive password figure during unlatching, profile of tooth is moved locking bar (2) reset, withdraw from U-shape lock bar (1) and realize this lock open and close purpose freely.

Claims

1. movable motorcycle power assist vehicle coded lock that comprises lock body, U-shape lock bar, it is characterized in that moulding the compound letter disk of zinc for five forms one group of five-digit number password, mould zinc compound packing and make the locating slot of ten five equilibriums, 36 degree according to the direction of locking plate at inner ring, following lock core in the lock core has five to press the hole up and down, in adorn five springs, profile of tooth moves locking bar and is loaded on up and down between the lock core, and two ends respectively have a circular hole, and each connection connects the elongated slot of one 10 mm wide in the inboard of circular hole.
