Problems solved by technology

[0003] The shaft length of the traditional spool is fixed, that is, the volume or space occupied by the spool is almost the same when it is fully loaded and empty. The empty spool has a huge storage space pressure during the turnover storage and transportation, which also makes the logistics cost high. , especially for large spools with a diameter of up to two meters, the unloaded logistics costs of the spools are particularly significant
Therefore, it is necessary to improve the structure of the spool, so that the volume occupied by the spool can be significantly compressed when it is empty. China Taiwan Patent TW538966U also improves on this idea, but the structure of the "hollow shaft" described in TW538966U is relatively Complicated, leading to inefficiency in spool telescoping operations, which is not favored by the market

Embodiment 1

[0029] Embodiment 1 (cylindrical telescopic structure)

[0030] Such as figure 1 with figure 2 As shown in the embodiment of the cylindrical telescopic structure of "a telescopic spool" of the present invention, on the virtual axis taking the line connecting the centers of the two panels 110 as the virtual axis, two small cylinders 120 and one large cylinder 130 are preferably combined to form a telescopic shaft One of the structures; the outer diameters of the two small cylinders 120 are equal to or slightly smaller than the inner diameter of the large cylinder 130; the two ends of the large cylinder 130 are respectively parallel to the direction of the virtual axis and preferably open two elongated "S or J ”-shaped combined seam (a total of four seams), the extension stop points of the seam are 131 and 134, and the compression stop points of the seam are 132 and 133; at the ends of the outer cylinders of the two small cylinders 120 The 180-degree symmetrical orientation i...

Embodiment 2

[0031] Embodiment 2 (total rod folding structure)

[0032] Such as image 3 with Figure 4 As shown, the general rod folding structure embodiment of "a telescopic spool" of the present invention takes the line connecting the centers of the two panels 211 and 212 as the virtual axis, and preferably equidistantly arrays four possible Folding total rod 220; every general rod 220 all comprises four short rods 221, 222, 223 and 224, and is connected into a foldable structure by bearings A, B, C; the short rods 221, 224 at the two ends of the total rod 220 are preferably The mode of welding is respectively fixed on the circumference of two panels 211 and 212 with the virtual axis as the center of the circle; It is a non-limiting free hinge structure connected by bearings; the short rod 222 and the short rod 223 at the midpoint of the total rod 220 are not only connected by a bearing C as a unilateral limited hinge structure, but also when the short rod 222 and the short rod The a...

Abstract

The invention discloses a telescopic thread spool which is of an I-shaped contour structure formed by respectively connecting one panel on each of two ends of a hollow shaft in series. The hollow shaft is of a cylinder telescopic structure or a total rod folding structure so as to achieve shaft length compression and expansion effects. Compared with a traditional thread spool and the disclosed telescopic thread spool invention concept, the telescopic thread spool has the advantages of simple structure, high operation efficiency and high use reliability.

Description

technical field [0001] The invention belongs to the field of manufacturing and using bobbins loaded with wire products such as electric wires and cables, cables or plastic pipes. The axial length of the spool can be expanded or compressed as the spool is loaded or unloaded. Background technique [0002] The spool is also called a reel, and a circular panel is connected in series at both ends of a hollow shaft and fixed into an "I"-shaped profile structure, which is used for winding loading and storage of flexible wires, cables, cables or plastic pipes and other wire products. [0003] The shaft length of the traditional spool is fixed, that is, the volume or space occupied by the spool is almost the same when it is fully loaded and empty. The empty spool has a huge storage space pressure during the turnover storage and transportation, which also makes the logistics cost high. , especially for large spools with a diameter of up to two meters, the unloaded logistics costs of...
