Abstract

The utility model relates to a brake fixing frame for a bicycle, which mainly solves the problem that the fixing frame has the defects of low intensity, easy damage and complicated assembly. The utility model is characterized in that an inlaid groove is arranged on a fixed shaft, and the external surface of the other end of the fixed shaft is provide with a screw thread; a cutting sleeve is hollow, the cutting sleeve is provide with an internal screw thread, and the cutting sleeve is inlaid into the inlaid groove after the cutting sleeve is screwed over the screw thread at one end of the fixed shaft. An external cover is in a stepped shape, one end of the external cover is provide with a bayonet, the external cover is sheathed in the inlaid groove of the fixed shaft, and a seat frame is fixed to the bicycle.

Description

The bicycle brake fixed mount

The utility model relates to a kind of bicycle brake fixed mount.

In prior art, general bicycle brake fixed mount solid forging or by anchor shaft with anchor shaft mutually the stand of scarf form, stand is welded on the bicycle, in anchor shaft, all has negative thread, brake is contained on the anchor shaft, the outside thread of bolt and anchor shaft negative thread match, screw threaded in anchor shaft in order to limit brake, owing in anchor shaft, have negative thread, so the processing technology more complicated again owing to the not end that bolt can not screw togather the anchor shaft inner bolt hole fully forms stress concentration, makes the anchor shaft fracture easily, and its assembling more complicated wastes time and energy.

The purpose of this utility model provides a kind of intensity height, not fragile and assemble simple bicycle brake fixed mount.

The utility model is made up of stand, bulge loop, anchor shaft, cutting ferrule and enclosing cover, between stand and anchor shaft, has bulge loop, it is characterized in that: on anchor shaft, have caulking groove, have screw thread, cutting ferrule hollow at the other end outside face of anchor shaft, cutting ferrule has negative thread, cutting ferrule revolves behind the anchor shaft threaded one end and embeds in the caulking groove, and enclosing cover is stepped appearance, has bayonet socket at an end of enclosing cover, enclosing cover is enclosed within the caulking groove of anchor shaft, and mounting is fixed on the bicycle.

Because anchor shaft of the present utility model does not have negative thread, anchor shaft has kept the bulk strength of original rigidity, so its intensity height, not fragile, again by on anchor shaft, having caulking groove, other end outside face at anchor shaft has screw thread, cutting ferrule hollow, cutting ferrule has negative thread, and cutting ferrule embedded in the caulking groove after revolving the anchor shaft threaded one end, enclosing cover is stepped appearance, end at enclosing cover has bayonet socket, and enclosing cover is enclosed within the caulking groove of anchor shaft, so when assembling, only need brake is contained on the anchor shaft, screw in cutting ferrule, buckle enclosing cover and get final product, assembling is simple.

Below in conjunction with accompanying drawing the utility model is elaborated,

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is an assembling scheme drawing of the present utility model,

Fig. 3 is the structural representation of another embodiment of the utility model,

See figures.1.and.2, between stand 1 and anchor shaft 2, has bulge loop 3, be provided with spring dog hole 4 on the bulge loop to cooperate the torsion spring between brake and the bulge loop, on anchor shaft, has caulking groove 5, other end outside face at anchor shaft has screw thread, cutting ferrule 6 hollows, cutting ferrule has negative thread, cutting ferrule revolved to embed in the caulking groove behind the anchor shaft threaded one end and was used to block brake, enclosing cover 7 is stepped appearance, end at enclosing cover has bayonet socket, and enclosing cover is enclosed within the caulking groove of anchor shaft, and mounting is fixed on the bicycle.

With reference to Fig. 3, anchor shaft 8, bulge loop 9 and stand 10 are three elements independently, and anchor shaft passes bulge loop and embeds stand, stand radially have a screw 11, on-slip screw 12 is fixed in the screw, anchor shaft is withstood on its top.

Claims
