A kind of disk brake shield
Technical field
The present invention relates to a kind of disc brake accessory, particularly a kind of being installed on prevents on the disc brake that muddy water from entering the protective cover of disc brake.
Background technology
Original disc brake that is installed on bicycle, the battery-driven car all is to expose outside, though be convenient to maintenance like this, but the full dust of disc brake inner product, silt, rainwater after the long-term use, brake facing and disc form an emery wheel, the wearing and tearing of brake facing have been quickened greatly, the deceleration and stopping performance of disc brake reduces, and situations such as slipping of brake often occur, influences traffic safety.For this reason, set up protective device on some disc brake, whole disc brake is surrounded, done not only not having protective action like this, and made troubles for the maintenance of disc brake, profile is not attractive in appearance yet; As everyone knows, disc brake is to utilize the tribology principle braking, and friction just can produce heat, and after whole disc brake was surrounded, fricative heat can not in time shed, and also can influence the deceleration and stopping performance of disc brake to a certain extent.
Summary of the invention
Problem to be solved by this invention just provides a kind of disk brake shield, and is simple in structure, easy for installation, can play the effect of protection disc brake, can not hinder the maintenance of disc brake again.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: a kind of disk brake shield, comprise the cover body of being located on the disc brake assembly adapter plate, it is characterized in that: be provided with the groove structure that matches with the disc edge part in the described cover body, described cover body is covered in the top of disc with half-surrounded by groove structure.
Further, described cover body is the semicircle plate-like, and described groove structure is for being located in the cover body and downward opening arc cavity.
Further, the part that covered by the arc cavity of disc is no more than half of disc main body.
Further, being provided with a circle dash along the opening part of arc cavity uses in one's ear.
Further, describedly be provided with the limited bayonet that the grafting adapter plate is used in one's ear.Before protective cover is installed, is plugged on the adapter plate by limited bayonet in advance and positions, guarantee that protective cover has correct installation site on adapter plate.
Further, the opening part of described arc cavity is set to the angle structure that cooperates with the adapter plate side.
Further, described angle structure is provided with the spacer that is used to lean the adapter plate side.After protective cover installs, rely on the adapter plate side by spacer, the medial surface of arc cavity can not contact with disc, guarantees that the installation of protective cover can not have influence on the rotation of disc.
Further, also be provided with the connecting portion that fixed enclosure is used on described cover body one side.
Further, have the radiating groove that communicates with the arc cavity on the described cover body side.
Beneficial effect of the present invention: the present invention is simple in structure, dismounting is all very convenient, can not only guarantee that silt, rainwater do not fall into disc brake assembly, and need not dismantle protective cover and also can carry out the maintenance of disc brake, and is convenient and practical; Limited bayonet makes the easier for installation, correct of protective cover in conjunction with the spacer structure, and can guarantee to make the installation of protective cover can not have influence on the rotation of disc; Being provided with of radiating groove can in time shed fricative heat, so the present invention not only has the good dust-proof effect, also has certain radiating effect and decorative effect.
Description of drawings
The present invention is done the explanation in a step below in conjunction with accompanying drawing:
Fig. 1 is a scheme of installation of the present invention;
Fig. 2 is a three-dimensional structure diagram of the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, preferred structure of the present invention, a kind of disk brake shield, comprise the cover body of being located on the disc brake assembly adapter plate 1, be provided with the groove structure 11 that matches with disc 2 edge parts in the described cover body 1, described cover body 1 is covered in the top of disc 2 by groove structure 11 with half-surrounded, and as preferred version: described cover body is the semicircle plate-like, and described groove structure is for being located in the cover body and downward opening arc cavity; The part that disc 2 is covered by the arc cavity is no more than half of disc 2 main bodys; Cover body 1 the opening part of arc cavity 11 extend outward that a circle dash uses in one's ear 12, describedly be provided with the limited bayonet 16 that the grafting adapter plate is used in one's ear, before protective cover is installed, be plugged on the adapter plate by limited bayonet in advance and position, guarantee that protective cover has correct installation site on adapter plate; The opening part of described arc cavity is set to the angle structure 14 that cooperates with the adapter plate side; On angle structure 14, be provided with the spacer 17 that is used to lean the adapter plate side, after protective cover installs, rely on the adapter plate side by spacer, the medial surface of arc cavity can not contact with disc, guarantee that the installation of protective cover can not have influence on the rotation of disc, limited bayonet makes the easier for installation, correct of protective cover in conjunction with the spacer structure.Cover body 1 one sides are provided with the connecting portion 15 that fixed enclosure is used, and this connecting portion 15 can be connected by screw class fastener with the disc brake assembly adapter plate; Have the radiating groove 13 that communicates with arc cavity 11 on cover body 1 side, not only have radiating effect, but also have certain decorative effect.
The present invention is simple in structure, dismounting is all very convenient, can not only guarantee that silt, rainwater do not fall into disc brake assembly, and need not dismantle protective cover and also can carry out the maintenance of disc brake, and is convenient and practical.
