Abstract
The utility model discloses an external pull box. A flange on the upper part of an instrument box is arranged on cambered fork ports of two supporting plates, and a flange on the lower part of the instrument box is connected with a spring coiling box; a top cover is arranged above the instrument box; a single flat spiral spring is arranged in the spring coiling box; a hook in the center of the flat spiral spring is buckled in a trench of a hollow shaft; a hook at the outer edge of the flat spiral spring is buckled on a double-face buckle of the spring coiling box; a pull line extends into a line coiling disc through a line penetration hole in the line coiling disc, is wound in a rectangular trench in a flange face of the hollow shaft, is inserted into a through hole in the center of the hollow shaft and then extends into a cavity of the instrument box; and a groove in the outer edge of a pulley I on a line guide device is engaged with a convex ridge on the outer edge of a pulley II to rotate oppositely. The external pull box has the advantages of reducing the weight, simplifying the structure, reducing the machining processes, lowering the manufacturing cost and bringing great convenience to mounting and use by changing the mounting mode according to circumstances compared with the pull box of the same type.
Description
Technical field
The utility model relates to a kind of terminal box, is a kind of monovolume spring external terminal box specifically.
Background branch art
At present, the terminal box that some backguys are more longer generally adopts the biplane volute spring, and the terminal box of this structure can cause related components to increase, and weight increases, and processing technology and fitting process be the complicacy of ten minutes also.
The utility model content
To the deficiency that above-mentioned prior art exists, the utility model provides a kind of external terminal box of processing the single plane scroll spring of employing simple, easy to install and use.
The technical scheme of the utility model is; A kind of external terminal box; Comprise instrument box, stay bearing plate, top cover, coil spring box, plane scroll spring, air-cored axis, winding roll, cable guiding device; It is characterized in that: the instrument box all be provided with flange up and down, the flange that is located at top is installed on the arc fork of two stay bearing plates, the flange that is located at the bottom is connected with coil spring box; The top of instrument box is provided with top cover, and air-cored axis passes through bearing installation on the axis of instrument box and coil spring box; Single plane scroll spring is installed in the coil spring box, and the hook at plane scroll spring center is buckled in the groove of air-cored axis, and the hook on the plane scroll spring outer rim is buckled on the double sided button of coil spring box; Line of pull extend in the winding roll through the through wires hole on the winding roll, after twining in the square type groove of line of pull on air-cored axis's flange face, again by inserting in the through hole at air-cored axis center and reaching in the cavity of instrument box; Cable guiding device is equipped with pulley I and pulley II, the fin on groove on the outer rim of pulley I and the pulley II outer rim chimeric in opposite directions the rotation.
Said instrument box and coil spring box bottom center are equipped with bearing mounting hole.
Said instrument box is circular.
The thickness of said plane scroll spring is 0.6～1 ㎜.
After this device was removed stay bearing plate, mounting column on the instrument box can be contained in terminal box on the required facility conversely.
The utility model has the advantages that: compare with the terminal box of same type, alleviated weight, simplify the structure, reduced work programme, reduced cost, and can according to circumstances change mounting means, make installation and use convenient.
