Technical Field

The invention relates to bicycle parts, in particular to an insert type bicycle auxiliary handle.

Background

The bicycle can be used as a travel tool and a sports tool, is environment-friendly and healthy, meets the requirement of green travel in the city, and is more and more favored by people. People can easily feel fatigue when riding in a fixed mode for a long distance, and the riding posture can be changed during riding, so that the fatigue can be relieved. Therefore, the two ends of the transverse handle of the existing mountain bike and road bike are basically provided with the auxiliary handles, so that a rider can hold the transverse handle of the bike by hands and can also hold the auxiliary handles by hands, and the fatigue can be relieved to a certain degree. However, most of the sub-handles are sleeved on the transverse handle, and the screw is locked by a tool such as a screwdriver, so that the sub-handle is fixedly arranged at the end part of the transverse handle in one posture. In order to adapt to various postures of riders, the screws can be loosened only by operating tools, and then the auxiliary handle is adjusted forwards or backwards at the original position as a fixed point, so that the use requirements of riders are met. This pair has two problems: firstly, the screw is directly exposed in the visual field of people, the beauty of the product is affected, and the exposed screw is easy to rust; secondly, after the position of the auxiliary handle is adjusted for many times, the screw is abraded, the service life is influenced, and particularly, when a bumpy road surface or an emergency occurs, a large torsional force is generated between the transverse handle and the auxiliary handle, the auxiliary handle has the possibility of rotating or even dropping off the transverse handle of the bicycle, and serious potential safety hazards exist.

Disclosure of Invention

Aiming at the defects in the problems, the invention provides an insert type auxiliary bicycle handle.

In order to achieve the above object, the present invention provides an insert type bicycle secondary handle, comprising a grip rod mounted on a bicycle handlebar and a locking assembly disposed in the grip rod, wherein the grip rod comprises a grip portion for gripping and a mounting ring portion capable of extending into an inner wall of the handlebar, the mounting ring portion has a first tapered surface formed on a right end and a plurality of shrinkage grooves formed in a longitudinal direction, the locking assembly comprises a bolt, an adjusting block and a mandrel, the mandrel is disposed in the mounting ring portion, the mandrel has a second tapered surface formed on a right end thereof, the second tapered surface is matched with the first tapered surface, the mandrel has a receiving hole formed on a left end thereof for receiving the adjusting block, the left side of the receiving hole is a first tapered surface, the left side of the adjusting block is a second tapered surface, and the first tapered surface has the same slope as the second tapered surface, the inner side surface and the outer side surface of the adjusting block are vertical surfaces, and the bolt penetrates through the holding part and is screwed with the adjusting block;

preferably, the bolt is provided with a spring gasket;

in above-mentioned technical scheme, the spring shim plays the not hard up effect of bolt that prevents, and is vice good to the fixed effect on horizontal.

Preferably, the holding part is provided with a cover plate connected by a buckle, the bolt is completely hidden in the inner cavity of the holding part through the cover plate, and the bolt is a hexagon socket head cap bolt;

in the technical scheme, the bolts are hidden, so that the product is attractive and elegant, and meanwhile, the bolts are not easy to be wetted and rusted; the internal hexagonal bolt is preferably selected to the bolt, and the internal hexagonal spanner that facilitates the use closes soon outside the inner chamber of the portion of gripping.

Preferably, the connecting part of the holding part and the mounting ring part is also processed with an annular embedded groove;

in the technical scheme, the transverse handle can extend into the embedded groove, and the end part of the transverse handle is completely hidden, so that the novel multifunctional embedded groove is very attractive.

Preferably, a shrinkage joint is processed on the right side of the adjusting block, and an opening of the shrinkage joint faces downwards;

in the technical scheme, the lower end of the right side of the adjusting block is always abutted against the right side face of the accommodating hole through the elastic action of the contraction joint, so that the effect of force couple on the bolt is counteracted conveniently.

Preferably, the right side surface of the adjusting block is an inclined surface with the inclination consistent with that of the second inclined surface;

in the technical scheme, the right side surface of the adjusting block is completely attached to the right side surface of the accommodating hole, and the bolt is not subjected to force couple.

Compared with the prior art, the invention has the beneficial effects that: the existing auxiliary handle is fixed and installed through a screw, so that the appearance is not attractive, and the hidden danger caused by insufficient locking force is easily caused along with the increase of the adjustment times of the auxiliary handle; the inserted block type auxiliary handle provided by the scheme has strong locking force, the auxiliary handle is not easy to fall off, the hidden design of the bolt is attractive and elegant, and the adjustment is convenient.
