Description

Theft-proof lock for motor cycle

The utility model belongs to the lock class, a kind of anti-lock for motorcycle of usurping.

The lock for motorcycle of Chu Shouing mainly contains two types in the market: a kind of is semifixed type, and promptly lock body is fixed on the front fork one side fork arm, and locking bar then is a separate type, and vertical at ordinary times mortise lock is on lock body.Earlier open the dial-out locking bar in the time of need shutting, locking bar is crossed and crosses and be inserted in the lock body lockhole and pin from the front fork opposite side with key.Because the high vibrations of speed are big during motorcycle driving, lock body glides, and locking bar is loosening, in the spoke bar, causes unexpected overturn accident before inserting automatically sometimes, and the traffic department in the area that has has prohibited and used this lock.Another kind is a lock body additive type lock in a tubular form,, on motorcycle, use hour locking lever to pass front fork width of cloth bar and pin without any partial fixing, not the time spent with whole lock hanging on after-frame.Trouble is not only opened, locked to this lock, and driving the time can constantly knock, and the people is upset, and influence the concentrated of motorist's notice.

The purpose of this utility model is the shortcoming at above-mentioned lock, manufactures and designs a kind of novel anti-theft lock for motorcycle.

The purpose of this utility model is achieved through the following technical solutions: the inner end of U-shape lock bar is with a fixed body and is fixed on the Motorcycle Front Fork one side fork arm, and lock body then is fixed on the opposite side fork arm.Link with two U shaped steel silks that collapse on the mud plate between locking bar fixed body and the lock body, with anti-loosening downslide.The locking bar fixed body is formed with projection by recessed, and recessed then links and make recessed and can rotate mutually with projection with rotating shaft with projection.For the purpose of practical and attractive in appearance, the ledge of projection falls into arc angle with recessed homonymy with respect to the position of projection two step, make the locking bar fixed body be fixed on the front fork after, recessed energy rotates an angle of 90 degrees by rotating shaft up and down around projection.The U-shape lock bar then passes the latch arm hole at recessed two and can slidably reciprocate therein.For the locking bar of opening can be close on the front fork stem, on the front fork stem of locking bar fixed body below clip be housed locking bar is clamped, to increase traffic safety.

Below in conjunction with accompanying drawing the technical solution of the utility model is further elaborated.

Fig. 1 is the utility model locking bar fixed body structure sectional view;

Fig. 2 is the utility model locking bar fixed body upward view;

Fig. 3 is the utility model locking-in state elevation;

Fig. 4 is the utility model exoneration state elevation (lock body slightly);

Fig. 5 is the utility model exoneration state left view (the lock alms bowl slightly).

With reference to Fig. 1, the locking bar fixed body is made up of recessed (1) and projection (2). There is latch arm hole (3) at recessed (1) two, and there is shaft hole (4) centre. Projection (2) has projection shaft hole (5) over against the place of recessed (1) shaft hole (4), and hole (4) is passed in rotating shaft (6) and hole (5) are connected recessed (1) and projection (2), and recessed (1) and projection (2) can be rotated mutually. With reference to Fig. 2, for the purpose of practical and attractive in appearance, arc angle is fallen into respect to the homonymy at the position of projection (2) two step in the bossing of projection (2) and recessed (1), makes the around the shaft relative 90-degree rotation of (6) energy angle of recessed (1) and projection (2). With reference to Fig. 3, locking bar fixed body (7) and lock body (8) are separately fixed at front fork two fork arms (13) outsides by clip (9), and U-shape lock bar (10) passes and inserts two lockholes on the lock body after two latch arm hole on recessed of the locking bar fixed body and a lock pins. This moment whole lock structure that is square, rigidity reinforced. The suitable local limited location village (11) on locking bar (10) two lever arms makes the rear unlikely locking bar fixed body (7) that skids off of locking bar (10) of lock exoneration, and with locking bar clip (12) locking bar (10) is fastened on (with reference to Fig. 4 and Fig. 5) on the fork arm.

That the utility model lock for motorcycle has is simple in structure, dependable performance, easy to manufacture, both artistic and practical, the convenience of unblanking, traffic safety, integral rigidity are strong, be difficult for by advantages such as sled are bad. The utility model lock once used at model motorcycles such as Honda CG125, Jiangling 70 and Yamahas 100, and effect is very good. When motorcycle runs at a high speed, takes a sudden turn even to predominate lower time, locking bar can not deviate to cause the accident yet. When the utility model lock is installed, with clip (9) locking bar fixed body (7) and lock body (8) are separately fixed on front fork two fork arms (13), locking bar clip (12) is contained on the appropriate location of fork arm below the locking bar fixed body (7) and gets final product. Operation of the present utility model is as simple and convenient as the bicycle lock: when needing to pin, with singlehanded the locking bar lower end is pulled out from clip, upwards carry and turn 90 degrees the angle to horizontal level, even if it is firm to push then lock body lockhole lock; In the time of need to opening, insert lock body with key and pull out locking bar, turn 90 degrees the angle to vertical direction to pressing down, its lower end is sandwiched in the clip get final product.

An embodiment of the present utility model: lock body (8) adopts the lock body of existing semifixed type lock, but its width should be consistent with the width of recessed (1).Recessed (1) wide 9-13 centimetre, long 2-4 centimetre, thick 1.5-2.5 centimetre, the wide 3-5 of negative area centimetre, long 1.5-2.5 centimetre; Wide 6-8 centimetre of projection (2), long 3-5 centimetre, thickness and recessed (1) consistency of thickness, bossing matches with recessed (1) negative area; Recessed (1) and projection (2) all form with cast steel, copper, aluminium or highstrenghtpiston's die-casting process; Locking bar (10) curves long 25-30 centimetre U type with diameter 10-12 millimeter garden steel.During assembling, the bossing of projection (2) inserted recessed (1) recessed place and allow shaft hole (4) and (5) over against, insert rotating shaft (6), locking bar (10) two arms are inserted two latch arm hole (3) on recessed (1), and spacing village (11) of riveting over, appropriate location gets final product on locking bar (10) two arms again.
