Description

A kind of lock of saddle of motorcycle

Technical field

The present invention relates to mechanical lockset, especially a kind of lock of saddle of motorcycle.

Background technology

In order to make full use of the space, the space that vehicle frame and covering surrounded, motorcycle seat cushion below is commonly used to lay battery or tool box etc., so motorcycle seat cushion is installed on the vehicle frame by the seat cushion lock usually, often opens and closes with convenient.Existing lock of saddle of motorcycle generally adopts mechanical lock structure, the concrete structure of different its locks of vehicle also is not quite similar, wherein the seat cushion of riding-type motorcycle (especially cross-country sport car) lock generally is made of lock, lock lid, dead bolt, cam and drag hook etc., be symmetrical arranged two dead bolts in the gathering sill that lock and lock lid form, drag hook is by the interlock of cam driven two dead bolts.This seat cushion lock locks 2 of motorcycle seat cushion width, and is higher to the coherence request of two dead bolts interlock, break down easily, and complex structure, more with material, the cost height.

Summary of the invention

The purpose of this invention is to provide a kind of lock of saddle of motorcycle, break down easily to solve existing lock of saddle of motorcycle, and the high problem of cost.

Technical scheme of the present invention is: a kind of lock of saddle of motorcycle, comprise lock, lock lid, drag hook and return spring, gathering sill is arranged on the lock, and the lock cover bolt is fastened on the lock gathering sill is hidden, and drag hook is located in the gathering sill, the leading section of drag hook is a dead bolt, drag hook is provided with slotted eye, is equipped with limited block near an end place in the slotted eye, and the limited block two ends are fixed on the lock, return spring is between an end and limited block of slotted eye, and lock is provided with location-plate.

The present invention is installed on the frame of motorcycle, is used with the lock that is installed on the motorcycle seat cushion.Limited block had both carried out spacing to return spring, can carry out drag hook again spacing, when drag hook is subjected to drag-line when pulling, drag hook compression return spring, at this moment the dead bolt withdrawal gathering sill of drag hook leading section can open motorcycle seat cushion.When needs are closed motorcycle seat cushion, the seat cushion rear portion is to pressing down, the dead bolt of the lock compressing drag hook leading section on the seat cushion makes tool return gathering sill, when the dead bolt hole of lock on the seat cushion during over against the dead bolt of drag hook leading section, dead bolt stretches out gathering sill again and enters in the dead bolt hole of lock on the seat cushion cushion lock under the effect of return spring.Owing to have only a dead bolt and dead bolt seat, keyed end can be arranged on the centre position of motorcycle seat cushion width, the purpose of firm locking can be reached equally, and its reliability can be guaranteed.

The present invention uses reliable and stable, is not easy to break down, and compares with the structure of existing lock of saddle of motorcycle of the same type, and simple in structure, part is formed few, can reduce manufacturing cost.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the B-B sectional view of Fig. 1;

Fig. 4 is the structural representation of drag hook 4 among the present invention;

Fig. 5 is the C-C sectional view of Fig. 4.

Among the figure: lock 1 lock covers 2 dead bolts, 3 drag hooks, 4 step 4a gathering sills, 5 punching press convex closure 5a return springs, 6 limited blocks, 7 location-plates, 8 bolts, 9 connecting holes, 10 connecting holes, 11 punching press convex closures 12

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:

In Fig. 1 to Fig. 5, gathering sill 5 is arranged on the lock 1, lock lid 2 usefulness bolts 9 are fastened on the lock 1 gathering sill 5 are hidden, drag hook 4 is located in the gathering sill 5, and the leading section of drag hook 4 is a dead bolt 3, and drag hook 4 is provided with slotted eye 4b, be equipped with limited block 7 near an end place in the slotted eye 4b, limited block 7 two ends are fixed on the lock 1, and return spring 6 is between the end and limited block 7 of slotted eye 4b, and lock 1 is provided with location-plate 8.

The side that Fig. 2 illustrates drag hook 4 is provided with limited step 4a and matches with the corresponding end face of lock 1, when drag hook 4 resets (dead bolt 3 that is drag hook 4 leading sections stretches out gathering sill 5 again) under return spring 6 effects, this step 4a carries out spacing to drag hook 4, at this moment the limited block 7 in the gathering sill 5 can be not and the end in contact of slotted eye 4b, but promptly 7 pairs of drag hooks of not-go end position piece this moment 4 carry out spacing.

The gathering sill 5 that Fig. 3 illustrates on the lock 1 is bent to form " U " shape groove structure through Sheet Metal Forming Technology, and used like this material is few, and makes manufacturing process simple, can reduce cost.

Be fixed on the lock 1 after the two ends that Fig. 1, Fig. 2 illustrate limited block 7 are stretched out gathering sill 5 two sides and are bent to form " Qian " shape structure, this structure makes limited block 7 easy for installation, solid and reliable.

Two inside walls that Fig. 1, Fig. 2 also illustrate gathering sill 5 are distributed with punching press convex closure 5a, thereby can reduce the contact surface between drag hook 4 and 5 liang of inside walls of gathering sill, reduce friction, and guidance quality is better.

As can be seen from Figure 1: it is plate shaped that drag hook 4 is positioned at gathering sill 5 outer parts, the end of drag hook 4 and location-plate 8 is all to 90 ° of side bendings, and on their bending segment, be provided with the relative connecting hole in position 10 and 11 respectively, be convenient to install drag-line, contact surface between drag hook 4 and the location-plate 8 is provided with punching press convex closure 12, and the contact surface between them is reduced to reduce friction.

During use, the present invention is installed on the frame of motorcycle, is used with the lock that is installed on the motorcycle seat cushion.Connecting hole 11 on the location-plate 8 is used for fixing protective sleeve of pulling cable, and the connecting hole 10 on the drag hook 4 is used for connecing the drag-line wire rope.When wanting to open motorcycle seat cushion, the pulling drag-line drives drag hook 4 compression return springs 6, and at this moment the dead bolt 3 withdrawal gathering sills 5 of drag hook 4 leading sections can open motorcycle seat cushion.When needs are closed motorcycle seat cushion, the seat cushion rear portion is to pressing down, the dead bolt 3 of lock compressing drag hook 4 leading sections on the seat cushion makes returns gathering sill 5, when the dead bolt hole of lock on the seat cushion during over against the dead bolt 3 of drag hook 4 leading sections, dead bolt 3 stretches out gathering sill 5 again and enters in the dead bolt hole of lock on the seat cushion cushion lock under the effect of return spring 6.The stroke end position of drag hook 4 under the drag-line wire rope drives represented in double dot dash line among Fig. 2.
