Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] see figure 2 , image 3 As shown, a handlebar stem base for bicycles includes a riser base body 1, one end of the riser base body 1 is a beam tube portion 2 for sheathing a handlebar, and the other end is a fixed stand The socket part 3 of the pipe, the socket part 3 is a C-shaped structure, and the upper and lower symmetrical positions of the opening 301 of the socket part 3 are provided with threaded holes, and the screws are screwed in the threaded holes. Tightening of the screw can tightly close the opening 301 of the socket part 3 , and the feature is that the opening 301 of the socket part 3 is an oblique opening.

[0015] The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and its purpose is to enable those of ordinary skill in the art to u...

Abstract

The invention discloses a handlebar riser base for a bicycle. The handlebar riser base comprises a riser base body; one end of the riser base body is provided with a riser restraint part for sleeving handlebars, and the other end of the riser base body is provided with a sleeving part for fixing a riser; the sleeving part is a C-shaped structure body; upper and lower screwed holes are symmetrically formed at an opening of the sleeving part; and screws are screwed in the screwed holes and the opening of the sleeving part can be tightly closed by screwing the screws. The handlebar riser base is characterized in that: the opening of the sleeving part is an inclined opening. The opening of the sleeving part of the handlebar riser base for the bicycle is the inclined opening, so that the surface layer of the riser can be effectively prevented from being broken or cracked due to clamping; meanwhile, due to the inclined opening, threads at one end of the C-shaped opening of the sleeving part is longer, and the locking force of the sleeving part can be effectively increased.

Description

[0001] technical field [0002] The invention relates to a standpipe seat, in particular to a handlebar standpipe seat for a bicycle. Background technique [0003] see figure 1 As shown, the known handlebar seat of a bicycle includes a seat body 1. One end of the seat body 1 is a tube portion 2 for the handlebar, and the other end is a fixed seat. The sleeve portion 3 is a C-shaped structure, and threaded holes are provided at the upper and lower symmetrical positions of the opening 301 of the sleeve portion 3. Screws are screwed in the screw holes, and the screws are passed through the screw holes. The opening 301 of the socket part 3 can be tightly closed by tightening it. The opening 301 of the socket part 3 is a horizontal opening. When the standpipe seat of this structure is used, a problem is often found: when the socket part 3 clamps the standpipe, it is easy to pinch or crack the surface layer of the carbon steel or composite tube standpipe.
