Description

Bicycle rider frame structure

The present invention relates to the field of bicycles, and in particular to a bicycle rider frame structure that provides riding safety and comfort.

As we all know, the handlebars on bicycles are at a fixed height, so they cannot be adjusted for individuals. Users of different heights can only ride with the handlebars at a fixed height. Riding for a long time can easily cause discomfort, and it will also cause problems for the user's posture and appearance.

However, when the known bicycle steering wheel is fixed to a front fork, usually only a tie is used to fix the bicycle steering wheel and the front fork at the same time. However, when the user turns the bicycle steering wheel and the front fork while riding, it is easy for the bicycle steering wheel and the front fork to shake with each other due to speed and ground bumps, making the vibration more severe and causing safety concerns.

In addition, the known bicycle steering wheel includes a headset, a head tube and an inner tube, the head tube and the inner tube are mutually interpenetrating, and the headset includes an upper headset and a lower headset, the upper headset and the lower headset are respectively connected to the two ends of the head tube and connected to the inner tube, so that the inner tube can be limited to the head tube and rotate relative to the head tube. Its structure is complex, with many components and high cost, so it is really necessary to improve it.

Therefore, in view of the above-mentioned problems of the conventional bicycle turning, the inventor of the present invention has devoted great efforts to develop the handlebar structure of the present bicycle. Therefore, the main purpose of the present invention is to provide a safe and stable handlebar structure of the bicycle with freely adjustable handlebar height; the secondary purpose of the present invention is to provide a simple and cost-effective handlebar structure of the bicycle.

In order to achieve the above-mentioned purpose, the present invention uses the following technical means: a bicycle handlebar structure of the present invention comprises: a faucet, wherein the faucet comprises an upper telescopic tube and a lower telescopic tube, wherein the faucet is connected to the upper telescopic tube, and the upper telescopic tube sleeve extends on an outer wall of the lower telescopic tube; a clamping fixture, wherein the clamping fixture is provided with a quick-release ear seat and a fixed ear seat, wherein the quick-release ear seat sleeve is provided on the upper telescopic tube, and wherein the quick-release ear seat is adjacent to the faucet; a fixing assembly, wherein the fixing assembly comprises a flower piece and a locking screw, wherein the locking screw extends through the flower piece and is connected to the telescopic tube. The bottom of the down tube; a front fork assembly, wherein the front fork assembly includes a front fork vertical tube, and the flower piece of the fixing assembly is connected to the inside of the front fork vertical tube, and the fixing ear seat of the clamping fixture is sleeved on the front fork vertical tube; and a fixing nut, wherein the fixing nut is connected to the front fork vertical tube and abuts against the fixing ear seat of the clamping fixture; the quick release ear seat of the clamping fixture is sleeved on the telescopic upper tube of the faucet and fixes the telescopic upper tube and the telescopic lower tube at the same time, and the fixing ear seat is sleeved on the front fork vertical tube and fixes the telescopic upper tube and the front fork vertical tube, and the telescopic upper tube is fixed by the quick release ear seat and the fixing ear seat respectively.

The quick-release ear seat of the above-mentioned clamping fixture further includes a quick-release handle, and the fixed ear seat further includes two screws.

The bottom of the extension tube of the faucet is provided with a first-class tube.

The extension down tube of the faucet is provided with a flange, and the quick-release ear seat of the emergency fastener is provided with a groove corresponding to the flange.

The bottom of the extension and lowering tube is provided with a screw hole, and the locking screw of the fixing assembly is inserted through the flower piece and then connected to the screw hole for fixing.

The above-mentioned faucet can be designed as a one-piece type or a split type.

The above-mentioned parts are arranged in the order of assembly from top to bottom: the faucet, the fastening fixture, the fixing nut, the extension and lowering tube, the flower piece, the locking screw and the front fork vertical tube.

Using the above technical means, the following effects can be achieved:

1. The quick-release ear seat of the emergency fastener of this new type fixes the extension upper tube and the extension down tube, and the fixed ear seat fixes the front fork riser and the extension upper tube, and the emergency fastener simultaneously fixes the upper tube and the lower extension tube. To adjust the height of the upper tube, the lower tube and the front fork vertical tube, you only need to open the quick release handle to quickly adjust the faucet and the upper tube. It is a safe, stable and comfortable bicycle rider frame structure.

2. The present invention uses the clamping fixture to clamp the telescopic upper tube, the telescopic lower tube and the front fork vertical tube, and the quick release ear seat is set on the telescopic upper tube and the telescopic lower tube. When the quick release handle is opened and loosened, the telescopic upper tube can be freely moved up and down for adjustment, thereby providing a bicycle handlebar structure with a simple structure, convenient manufacturing and low cost.
