Problems solved by technology

[0003] The left and right handlebars of the fixed handlebar are fixed horizontally on the front arm, and the front arm is fixed on the head shaft. The fixed handlebar is firmly combined without looseness. The disadvantage is that the space occupied by the bicycle is large.
This kind of operation is troublesome. If the angle and pressure of the handle are not adjusted properly, the handlebar will loosen the structure of the lock body due to vibration stress during riding, causing a certain degree of safety hazard.
[0007] 3. Threaded handlebars: The handlebars are connected to the front arm in a threaded manner, but the separated handlebars have no place to store and are not easy to store. In addition, the threaded handlebars are troublesome to assemble and the action is slow. The most deadly is the handlebar thread The damage directly makes the handlebar unable to be installed practically

Embodiment Construction

[0029] The main structure of the self-locking folding handlebar of the present invention comprises left and right handlebars 1, 2 and front arm 3, as figure 2 As shown, the front arm 3 is a "T" shape formed by a longitudinal section and a transverse section, and the tail portions of the left and right handlebars 1 and 2 are installed in the longitudinal section of the front arm 3, and the tail end casings of the 3 transverse sections of the front arm It is fixedly connected with the machine head shaft 14, such as figure 1 As shown, the left and right handlebars 1 and 2 are opened horizontally and are in a closed state for riding.

[0030] The longitudinal section and the transverse section of the front arm 3 are hollow structures with a cover on the top, such as figure 2 shown. Left and right handlebars 1,2 are provided with left and right fan-shaped synchronous teeth 8 integrated with left and right handlebars 1 and 2 below the tail portion, and the center of fan-shaped s...

Abstract

The self-locking folding handlebar has one right handlebar and one left handlebar with synchronous tooth meshed and hinged inside head arm and capable of rotating to fold symmetrically and synchronously; and one control stick for the separation of a conic sleeve from the conic pin to make the right handlebar and the left handlebar turn downwards automatically into the vertical folding state. The present invention also has one pick-proof built-in lock to make the right handlebar and the left handlebar perpendicular to each other and the bicycle incapable of being ridded. The present invention has self-locking, fast and smooth folding and small size.

Description

(1) Technical field: [0001] The invention relates to a handlebar, in particular to a self-locking folding handlebar. (two) background technology: [0002] There are two types of handlebars used for bicycles, tricycles, motorcycles, motorcycles, etc.: fixed and folding. Take bicycles as an example: [0003] The left and right handlebars of the fixed handlebar are horizontally fixed on the front arm, and the front arm is fixed on the head shaft. The fixed handlebar is firmly combined without loosening. Its shortcoming is that the space occupied when the bicycle is parked is large. [0004] There are mainly the following types of folding handlebars used in conjunction with folding bicycles [0005] 1. Plug-type folding handle: After the left and right handlebars are locked and closed in the front arm, you need to insert the plug on one side of the lock body to fix the handle. The insertion pin used in this one-way insertion method is an equal-diameter cylinder, and the cylind...
