Description

The compound type packing element

Technical field

The utility model relates to a kind of compound type packing element for winding yarn.

Background technology

Packing element is used for winding yarn, is to be absolutely necessary in the textile enterprise, and each ingot yarn all needs a packing element, and its consumption is huge.Packing element is generally cylindrical structure, and its center offers and the centre hole that twines shaft diameter and match, owing to twine the certain value that typically has a diameter from of axle, typically having a diameter from of this centre hole is constant.But the yarn of different size need to use the packing element of different-diameter, so the yarn that the packing element of multiple different size adapts to different size need to be prepared by textile enterprise, its cost is higher.

The utility model content

Technical problem to be solved in the utility model is: a kind of compound type packing element is provided, and the yarn that they can compatible two kinds of different sizes, thus reduce cost.

For addressing the above problem, the technical solution adopted in the utility model is: the compound type packing element, comprise an inner core and a urceolus, described inner core and urceolus are cylindrical structure, the inner core center is provided with and the centre hole that twines shaft diameter and match, the urceolus center is provided with the centre hole that matches with the inner core external diameter, is provided with at least one projection on the inwall of urceolus one end, is provided with the groove corresponding with projection on the outer wall of inner core one end.

The beneficial effects of the utility model are: above-mentioned compound type packing element, it can come compatible two kinds of yarns by making up, thereby greatly reduces the cost of textile enterprise.

The specific embodiment

Below by specific embodiment the utility model compound type packing element is described in further detail.

The compound type packing element, comprise an inner core 1 and a urceolus 2, described inner core 1 and urceolus 2 are cylindrical structure, as shown in Figure 1 and Figure 2, inner core 1 center is provided with and the centre hole 3 that twines shaft diameter and match, as shown in Figure 3, Figure 4, urceolus 2 centers are provided with the urceolus centre hole 4 that matches with inner core 1 external diameter, be provided with at least one projection 5 on the inwall of urceolus 2 one ends, on the inwall of urceolus 2 one ends, evenly be provided with four projections 5 along annular in the present embodiment, be provided with the groove 6 corresponding with projection 5 on the outer wall of inner core 1 one ends.

During use, inner core 1 can be used as an independent packing element and uses, and it is applicable to a kind of yarn; In addition, urceolus 2 can be sleeved on inner core 1 outside, and by the locking that cooperate realize hoop of projection 5 with groove 6, can be used as packing element behind the suit and use, it is applicable to another kind of yarn.

The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.

Claims

1. compound type packing element, comprise an inner core and a urceolus, it is characterized in that: described inner core and urceolus are cylindrical structure, the inner core center is provided with and the centre hole that twines shaft diameter and match, the urceolus center is provided with the centre hole that matches with the inner core external diameter, be provided with at least one projection on the inwall of urceolus one end, be provided with the groove corresponding with projection on the outer wall of inner core one end.
