Description

Telescopic double-pull data line device

Technical Field

The utility model relates to a data line device technical field, concretely relates to telescopic two data line devices that draw.

Background

The data line is an essential accessory in modern electronic life, and is mainly used for charging or data transmission of electronic equipment such as mobile phones and cameras. The existing data line generally comprises an equipment interface with one end used for connecting electronic equipment and a USB interface with the other end used for connecting a charger, and the existing data line is inconvenient to carry because the data line is generally long, and is easy to wind with other objects if directly placed in a desk or a bag, so that inconvenience is brought to the use of a user. Therefore, various telescopic double-pull data wires are invented, and the basic structure of the data wire is that a spring (spiral shrapnel) is arranged in a shell and is connected with a winding roll, the wire of the data wire is wound on the winding roll, and balls are also arranged on the winding roll for positioning. The data line is loose the hand gently after pulling out, and under the spring action of clockwork spring, the take-up reel can rotate, and the ball can fall into the stuck point along the slot roll, and the take-up reel can stop rotatory this moment, and the data line no longer retracts to realize the location of data line. However, such data wires have problems that, firstly, when the winding roll rotates, the balls roll simultaneously, the noise is large, and at the same time, the data wires are not smoothly stretched and are easy to be clamped; secondly, when the data line is pulled out, two ends of the double pull lines need to be pulled by two hands, and if only one side is pulled, the data line is easy to be blocked; thirdly, the balls roll easily and fall off, which causes the assembly of the product to be troublesome.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is prior art's defect provides a simple structure, reasonable in design, no matter be unilateral acting as go-between, still both sides act as go-between can not block dead, the noise is littleer when acting as go-between telescopic two data line devices that act as go-between.

In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a telescopic two data line devices that draw, including casing, rotary mechanism, data line and actuating mechanism, rotary mechanism is connected with actuating mechanism and sets up in the casing, and the data line is around establishing on rotary mechanism, and the both ends of data line are stretched out in order to form two line structures of drawing, its characterized in that from the casing: a guide piece is arranged on the rotating mechanism, and a guide column is arranged on the guide piece; a guide cover is also arranged in the shell, an arc-shaped ring-shaped guide groove is formed in one surface of the guide cover facing the guide piece, and a concave arc-shaped clamping point groove is formed beside the guide groove; the guide post of the guide piece is embedded in the guide groove to form a structure which can slide along the guide groove along with the rotation of the rotating mechanism, and the guide post slides into the click groove to form a positioning structure for the rotating mechanism.

Further, the guide groove is arranged in the central area of the guide cover and comprises an inner guide groove and an outer guide groove, an inner guide part is arranged in the middle of the inner guide groove, and the outer guide groove and the inner guide groove are separated by an outer guide ring; the inner edge and the outer edge of the inner guide part and the outer guide ring both adopt arc structures, a first notch and a second notch are arranged on the outer guide ring, the two notches are respectively positioned on the outer sides of the two sides of the inner guide part, and the inner guide groove and the outer guide groove are communicated with each other through the first notch and the second notch; the clamping point groove is arranged at one end, facing the first gap, of the outer guide ring; and an arc-shaped pushing part is arranged at the position, aligned with the second notch, of the inner wall of the outer guide ring.

Further, the guide member has a square frame structure, and the guide post protrudes from a side thereof facing the guide cover and is embedded in the guide groove.
