Abstract

The utility model relates to an improved safety lock for a motorcycle. The main lock body and the auxiliary lock body of the utility model are provided with clamping columns and clamping holes on positions corresponding to the disc hole of a brake disc, wherein, in order to realize an effect that the entirety of the utility model with smaller volume can match with the blocking of the brake disc, the ends of a group of clamping columns, steel balls and clamping ring grooves control the steel balls to clamp in the clamping ring grooves through the rotation of a lock core; besides, the steel balls and clamping ring grooves are correspondingly arranged on the clamping holes and are controlled by the lock core.

Description

Improved safety lock for motorcycle

The utility model relates to a kind of structure improved anti-theft lock for motorcycle, and it is a kind of lockset that is used on the motorcycle brake dish.

Present general lock for motorcycle structure, see also shown in Figure 3, two shock-absorbing bars, 11 ends at motorcycle 10 set up a wheel shaft 12, wheel shaft 12 is provided with brake disc 13 and tire 14 simultaneously, wherein, be laid with dish hole 130 on the brake disc 13, and the inner edge of tire 14 is supported by wheel frame 140, wheel frame 140 to wheel shaft 12 is established spoke 141,141 of spokes respectively are provided with wheel crack 142, the motorcycle lockset can cooperate this to take turns crack 142 lock to establish, and its lockset 30 mainly has a lock body 31 and cooperates a lock hook 32 that can pass wheel crack 142, and so structure is real a following shortcoming.Such as:

1. lockset 30 volumes are excessive: not only collection is difficult for; and in this lockset 30 of front-wheel place pull; regular meeting is subject to left and right restriction of parking motorcycle side by side; and can't smoothly lockset 30 be drawn back or sealed; and the narrow thickly vehicle of people is many again at present; the crowded of ten minutes arranged in parking of motorcycle, makes the use of this lockset 30 feel more inconvenience.

2. destroyed easily: the part of its lock hook 32, blocked very easily with instrument, theftproof is poor.

Main purpose of the present utility model is: a kind of structure improved anti-theft lock for motorcycle is provided, can reduces integrally-built volume really, more can improve the whole convenience of using and certain anti-theft effect.

The utility model provides a kind of structure improved anti-theft lock for motorcycle, comprises two lock bodies of establishing relatively, and a lock body is provided with core therein, it is characterized in that:

This two lock bodies opposing end surface is provided with card post and the hole clipping with suitable distance respectively, each blocks the dish hole that post penetrates brake disc, and a card styletable is provided with the steel ball of core control, is provided with annular groove in its corresponding hole clipping, steel ball and annular groove inlay card or disengaging mutually make the sealed or unlatching of two lock bodies.The utlity model has following advantage:

1. easy to use: because lockset of the present utility model is fixed in the brake disc both sides, only needs the degree of projection to exceed brake disc and get final product to the distance between the shock-absorbing bar, volume is very little, no matter collects or use all convenience of ten minutes.

2. operate simple and easy: very little of whole lockset opereating specification, all be confined to the both sides of brake disc, need not significantly pull action, the possibility that hindered by both sides motorcycle or article greatly reduces, can improve the convenience of lockset when locking or unlatching relatively, reach the purpose that simple and convenient is gone up in operation.

3. anti-theft effect is good: after lockset is incorporated on the brake disc, be exposed to outside structure, be the powerful lock body structure of structure, to destroy with instrument, no matter saw or blow, all there is its great difficulty to exist, strengthen antitheft effect virtually, and generally the thickness of brake disc all becomes normalized design, card column length of the present utility model also becomes normalized design, make when two lock bodies are sealed to be integral, very narrow and small of both sides that clamp brake disc that just can be certain, issuable space, instrument is difficult to put forth effort, nature can't destroy with instrument, antitheft effect height very.

Two of the utility model two lock bodies card post distances are about the distance in three to four dish holes of brake disc in addition, distance so, make main lock body when placing brake disc, the different dish hole of selection that can be random places, if the form that lay in the dish hole, non-general shown in the utility model accompanying drawing, when forming other form configurations, also can place cooperation easily.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.

Brief Description Of Drawings:

Fig. 1 is the three-dimensional schematic diagram of implementing of the present utility model.

Fig. 2 is a combination schematic diagram in plane of the present utility model.

Fig. 3 is existing lockset schematic perspective view.

See also Fig. 1, shown in Figure 2, the utility model mainly is a kind of lockset 20 that applies on the motorcycle brake dish 13, it mainly has two relative masters,

auxiliary lock body

21,22, wherein, main lock body 21 integral body are the L shaped cylinder of a perfectly round shape, and auxiliary lock body 22 also is the cylinder of a fillet shape, and two lock bodies 21, on the 22 relative straight end faces at a distance of the suitable columned card post 210 of each projection of distance, 220 and hole clipping 211,221, card post 210,220 external diameter is slightly less than the dish hole 130 of brake disc 13, and the card post 210 of main lock body 21, its hole clipping 221 end peripheries that stretch into auxiliary lock body 22 are established the two collapsible or steel balls 212 that are pushed out, and hole clipping 221 relative steel balls 212 places establish the annular groove 222 of annular recess, stretch out part to timing for steel ball 212, can embed the forms that form mutual snap close in the annular groove 222.

And the steel ball 212 that card post 210 is provided with is held in addition, establish a lock core hole 213 in the main lock body 21, for a core 23 establish into, give prominence to or be set back in card post 210 by the steel ball 212 that core 23 gets final product on the control card post 210, and be somebody's turn to do the non-genus of the core 23 internal constructions characteristic of the present utility model place of controlling steel ball 212, so do not give unnecessary details at this.

Lockset 20 of the present utility model is when using, after the dish hole 130 of the 210 relative brake discs of the card post on the

main lock body

21,13 appropriate positions can being passed, auxiliary lock body 22 can also pass dish hole 130 by brake disc 13 opposite sides by this card post 220, mutually with hole clipping 211,221 alignings and fastening, in to fashionable, the steel ball 212 of core 23 controls bounces back in the card post 210, after treating to plug together mutually, rotation lock core 23 can make steel ball 212 releases and the annular groove 222 of hole clipping 221 snap into sealed form again, and make two

lock bodies

21,22 sealed being integral, and being fixed in the both sides of brake disc 13, this brake disc 13 is by two

lock bodies

21,22 outstanding form can produce the phenomenon of blocking with shock-absorbing bar 11, naturally form one and have the structure of anti-theft effect, and in the time will opening lockset 20, only key will be inserted and rotate in the core 23, steel ball 212 can be set back in the card post 210, break away from annular groove 222, two

lock bodies

21,22 can be separated by brake disc 13, collection in addition, and ten minutes is quick and convenient in the use.
