Abstract

The utility model discloses a folding tap, which comprises a support rod and handles which are arranged on the two ends of the support rod, wherein a connecting position of the handles and the support rods are provided with folding joints which lead the handles to downwardly fold. The folding tap has the beneficial effects that the folding tap can be downward folded through the two handles of the tap, thereby reducing the total width of the tap, and further reduces the volume of a total folding bicycle after folding.

Description

Folding handle-bar stem

Technical field

The utility model relates to a kind of folding handle-bar stem, and this folding handle-bar stem is mainly used on folding bicycle or the battery-driven car.

Background technology

In recent years, various folded bicycles as folding bicycle, electric motor bicycle with folding, because it is deposited with easy to carry, more and more are subjected to customer's favor.

But also there is the place that requires further improvement in existing folded bicycle, and is wide more a lot of than vehicle body as the tap part, and the tap part takes up space big.

The utility model content

At the problems referred to above, the purpose of this utility model is to provide a kind of folding handle-bar stem, to solve the tap big problem that taken up space in the prior art.

To achieve these goals, the technical solution of the utility model is as follows:

Folding handle-bar stem comprises strut bar and the handgrip that is arranged on the strut bar two ends, it is characterized in that, the junction of described handgrip and strut bar is provided with the folding joint that makes handgrip folding downwards.

Further, in the utility model, the two ends of described strut bar are hollow structure, and the port, two ends of strut bar is provided with is convenient to the notch that turning cylinder produces, the annular external member that described folding joint comprises the anchor shaft that is arranged in the strut bar port, the turning cylinder that can rotate around this anchor shaft, be sleeved on this turning cylinder and can move forward and backward along this turning cylinder and be arranged on spring in the handgrip; Annular external member movable set is on strut bar; One end of spring is connected with handgrip, and the other end is connected with annular external member.

Further, in the utility model, also be provided with a square registration arm in the described strut bar port, described anchor shaft is arranged in the square registration arm, described square registration arm is provided with is convenient to the opening that turning cylinder produces, and described annular external member is provided with the square hole that is used to be sleeved on the square registration arm.Square registration arm in the strut bar port and the square hole on the annular external member match, and play a positioning action, prevent folding handle-bar stem of the present utility model under folded state not, handgrip generation axial rotation.

The beneficial effects of the utility model are:

By using folding handle-bar stem of the present utility model, two handles that can tap turn down downwards, reduce leading single-piece width, further reduce the volume behind whole folded bicycle folding.

Folding handle-bar stem of the present utility model is under folded state not, and handgrip axial rotation can not take place.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments:

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

Fig. 2 is an exploded view of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1 and 2, a kind of folding handle-bar stem comprises strut bar 130, handgrip 110, folding joint 120.Handgrip 110 is arranged on the two ends of strut bar 130, and handgrip 130 is provided with the folding joint 120 that makes handgrip folding downwards with the junction of strut bar 110.

In the present embodiment, the two ends of strut bar 130 are hollow structure, and the port, two ends of strut bar is provided with and is convenient to the notch 132 that turning cylinder produces.Also be provided with a square registration arm 131 in the strut bar port, square registration arm is provided with is convenient to the opening that turning cylinder produces.Folding joint comprises anchor shaft (not indicating among the figure), turning cylinder 121, annular external member 122, spring 123.Anchor shaft is fixedly installed in the square registration arm 131, and an end of turning cylinder 121 is connected with anchor shaft and can rotates around this anchor shaft, and the other end of turning cylinder 121 inserts in the handgrip 110.The annular external member is provided with the square hole that is used to be sleeved on the square registration arm.Being sleeved on the square registration arm 131 of annular external member 122 activities is to prevent folding handle-bar stem of the present utility model under folded state not, handgrip generation axial rotation.Spring 123 is arranged in the handgrip 110, and an end of spring 123 is connected with handgrip 110, and the other end is connected with annular external member 122.

The folding process of present embodiment: overcome spring force earlier and outwards pull out handgrip 110, under the effect of spring tension, annular external member 122 outwards moves, after annular external member 122 and square registration arm 131 break away from, to pressing down handgrip 110, the anchor shaft of turning cylinder 121 in square registration arm of folding joint rotates, and finishes folding.

More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in the foregoing description and the specification sheets is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
