Embodiment
Referring to Fig. 2 a and Fig. 2 b, the utility model one embodiment provides a kind of slide block abrasion cover 1, wherein, slide block abrasion cover 1 in the form of a ring, be provided with positioning convex 13 on the inwall 12 of described slide block abrasion cover 1, described positioning convex 13 moves with restriction slide block abrasion cover 1 rotation and line style relative to brake head 2 in the groove (scheming not shown) that is embedded on the brake head 2.
Slide block abrasion cover is antiwear easily-consumed products, and its material is nonmetallic material, such as nylon or plastics.
Referring to Fig. 2 a, Fig. 3 a and Fig. 3 b, at slide block abrasion cover 1 inwall 12 positioning boss is set, cast out groove at brake head 2, positioning boss is embedded in the groove after the assembling, to prevent that assembling rear slider abrasion cover 1 breaks away from brake head 2.Before the assembling, brake head 2 is fixing, slide block abrasion cover 1 is just being faced with brake head 2 slider ends, by applying external force in slide block abrasion cover 1 exterior edge face, make slide block abrasion cover 1 that plastic deformation occur, the positioning boss of slide block abrasion cover 1 slips in the groove on the brake head 2, and slide block abrasion cover 1 resiles, and assembling is finished.Need to change the slide block abrasion in the repair and maintenance and overlapped 1 o'clock, by applying external force slide block abrasion cover 1 is backed off, or with after slide block abrasion cover 1 destruction, more renew part.
In the prior art, riveted structure is adopted in being connected between slide block abrasion cover and the brake head, need to adopt special tool and frock to remove and rivet when changing slide block abrasion cover, can't carry out scene replacing.The slide block abrasion cover that adopts technique scheme to provide utilizes the moulding distortion of nonmetallic material to assemble, and can realize quickly and easily on-the-spot the replacing.
Further, the cross section of positioning convex 13 shape triangular in shape.
Herein, the direction of cross section refers on the globular projection direction of slide block abrasion cover.On stereogram, the height that the cross section of positioning convex shape triangular in shape shows as positioning convex differs, and the high side of a side is low, and to show as the dark side of a side shallow for corresponding groove with it.Positioning convex adopts above-mentioned shape to be convenient to be embedded in the groove of brake head.
Herein, alternatively, the rounded or rectangle of face that positioning convex 13 contacts with the inwall 12 of slide block abrasion cover 1.
In the practical application, the positioning convex of above-mentioned shape is convenient to make and is formed.
For the reliability that further guarantees to be connected between slide block abrasion cover 1 and the brake head 2, the quantity of positioning convex 13 is a plurality of, and scattering device wears away at slide block and overlaps on 1 the inwall 12.Particularly, can evenly distribute along the circumferential direction of slide block abrasion cover 1 ring-type direction.
