Detailed Description

Fig. 1-3 are schematic structural views of the present utility model, a plastic pipeline fixing device, including a rear shell 1 and a front shell 2, the front shell 2 is rotatably installed in the rear shell 1, a winding drum 3 is fixedly installed on the front shell 2, a middle partition board 4 is fixedly installed on the winding drum 3, the middle partition board 4 divides a space between the rear shell 1 and the front shell 2 into two winding cavities, the width of the winding cavities is slightly larger than that of a pipeline 5, a communication port 41 for penetrating the pipeline 5 is provided on the middle partition board 4, an outgoing port 11 is respectively provided on an outer circle of the rear shell 1 corresponding to the two winding cavities, compression spring pieces 6 are fixedly installed at the two outgoing ports 11, free ends of the compression spring pieces 6 are respectively suspended and extended into the two winding cavities, and one side of the compression spring pieces is abutted to the outermost ring of pipeline 5.

The width of the winding cavity is slightly larger than that of the pipeline 5, so that the pipeline 5 is wound in one row, and the winding and unwinding processes are more stable.

The communication port 41 is located at the connection root of the middle partition plate 4 and the winding drum 3, and an inclined guide groove can be formed to guide the pipeline 5 and play a supporting role, so that the pipeline 5 is prevented from being flattened when passing through the middle partition plate 4.

When in use, the pipeline 5 passes through the communication port 41 and is wound on the winding drums 3 at two sides of the middle partition plate 4, the winding directions of the pipeline 5 in the winding cavity are the same, and two ends of the pipeline 5 extend out of the two leading-out ports 11 respectively. When the length of the pipeline 5 is too long, the front shell 2 is rotated in the direction opposite to the winding direction of the pipeline 5, the pipeline 5 is continuously wound in the winding cavity, the pipeline 5 is received in the winding cavity and is tightly attached to the adjacent inner ring under the action of the compression spring piece 6, loosening is avoided, and the exposed lengths of the two ends of the pipeline 5 are shortened. When the length of the pipeline 5 is too short, the front shell 2 is rotated towards the winding direction of the pipeline 5, so that the two ends of the pipeline 5 can be pushed out from the leading-out port 11, and the compression spring piece 6 also plays a role in compression and guiding, so that the pipeline 5 is smoothly led out, and the use requirement of the pipeline is met.

Preferably, a positioning boss 12 is provided on an end surface of the rear case 1, and the winding drum 3 is rotatably mounted on the positioning boss 12.

Preferably, a front end ring 13 is formed by inwardly shrinking the front end of the outer circle of the rear shell 1, and the front end ring 13 abuts against the front end surface of the front shell 2.

Preferably, a rotating handle 21 is arranged on the front shell 2, a spring bolt 7 is arranged on the rotating handle 21, and the end part of the spring bolt 7 is abutted in positioning holes which are correspondingly and uniformly distributed on the front end ring 13.

The spring bolt 7 is slidably mounted on the rotary handle 21 and abuts in the positioning hole under the action of the spring. When the spring bolt 7 is used, the spring bolt 7 is pulled outwards, the spring bolt can be pulled out of the positioning hole, then the front shell 2 is driven to rotate, and the spring bolt 7 is released to a proper position, so that the spring bolt is clamped into the positioning space.

Through setting up spring bolt 7, make things convenient for preceding shell 2 to rotate, simultaneously after adjusting the length of pipeline 5, make backshell 1 and preceding shell 2 relatively fixed, avoid pipeline 5 not hard up.

Preferably, the pressing spring 6 is arc-shaped, and the middle part of the pressing spring is arched towards the side far away from the winding drum 3. The compressing spring 6 has better guiding function on the pipeline 5, and when the front shell 2 is reversed, the two ends of the pipeline 5 can be naturally pushed out from the leading-out port 11, so that the length of the pipeline 5 is convenient to adjust.

Preferably, a clamping device 8 for connecting the bracket is arranged on the rear end face of the rear shell 1. The clamping means 8 may be a spring clip structure.
