Abstract

An expanding hanger consists of a screw-thread conical head shaft, an expanding sleeve, a tightening nut, a spring, a positioning cover and a hoisting ring, and is characterized in that screw threadsare formed at the upper part of the screw-thread conical head shaft, a conical head is arranged at the lower part thereof, the conical head is narrow at the upper part and wide at the lower part; theexterior of the screw-thread conical head shaft is sleeved with the expanding sleeve, and the spring is arranged between the interior of the expanding sleeve and the shaft; the positioning cover is arranged outside the expanding sleeve, and the tightening nut is arranged on the positioning cover; and the hoisting ring is arranged at the top of the shaft. The utility model solves the problems of inconvenience caused by using a trolley for transportation and influence on product appearances caused by using a sling for transportation. The utility model provides the expanding hanger which has theadvantages that goods with any specification and weight can be transported, the appearance of the products can not be influenced, and the use is safe, convenient and simple.

Description

The expanding suspender

[technical field]

The utility model relates to the coiled material hoist tool, relates in particular to a kind of expanding suspender.

[background technology]

At plastic film sheet material and paper industry, the wide cut of rolling (2.5 meters ~ 3.5 meters) product is the rouleau that the needs that satisfy the client must cut into various different sizes, through dispatching from the factory after the packing.Be sent in the process of package post at the rouleau product that the cutting machine branch cuts out, general manual waggon carrying or the suspender belt of adopting lifts carrying, carry with the mode of manual waggon with regard to being not suitable for if having, and conveying efficiency is lower labor intensive above the finished product more than the 100kg.And when overweight finished product need be carried with lifting, need be with suspender belt around being hung under the finished product, handling then, because the quality of product own is big, suspender belt will bear total weight, hangs volume so can tie tight deeply, stays impression to finished product, influences product appearance.

[summary of the invention]

The utility model provides a kind of any specification, weight of transporting for addressing the above problem, and does not influence product appearance, simple expanding suspender safe and convenient to use.

The technical scheme that the utility model addresses the above problem is: described expanding suspender is made up of screw thread conehead axle, expanding sheath, fastening nut, spring, location lid, suspension ring, screw thread is arranged at the top that it is characterized in that screw thread conehead axle, conical head is arranged at the bottom, and the top of conical head is narrow, and the bottom is wide; Outside at described screw thread conehead axle is with expanding sheath, and described expanding sheath top is complete jacket casing shape, and the lower part is open tail end, is split up into 2-5 lobe expanding plate, is that center ring is around uniform with the axle center of screw thread conehead axle.The open tail end of described expanding plate is against the conical head middle part of screw thread conehead axle, is provided with Skidproof structure at the outside face of described expanding plate, and described Skidproof structure is a dentation; Between expanding sheath inside and the axle spring is arranged; Be provided with the location lid outside expanding sheath, the location lid can be stuck on the axle center end face of spool, realizes the location with this; The location covers and is provided with fastening nut, controls the lifting of screw thread conehead axle with fastening nut; The top at axle is provided with suspension ring, in order to the lifting spool.

There is cascaded surface described conical head and axis body junction, and the place is provided with backing plate at cascaded surface.

Described spring is arranged between expanding sheath inside and the screw thread conehead axle, and one is against expanding sheath inside, and one is against on the backing plate.

The beneficial effects of the utility model are: the utility model extend into the volume in-core of spool with suspender, utilizes the tension force of expanding plate power to lift by crane the carrying spool, and this mode is simple, the efficient height, lost labor not, and can not influence the outward appearance of product, keep product attractive in appearance.

[description of drawings]

Fig. 1 is the utility model one example structure scheme drawing;

Fig. 2 is the cutaway view of Fig. 1.

Among the figure: 1, screw thread conehead axle; 1.1, conical head; 2, expanding sheath; 2.1, expanding plate; 2.2, dentation; 3, fastening nut; 4, spring; 5, location lid; 6, suspension ring; 7, backing plate.

[specific embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

With reference to accompanying drawing, as seen described expanding suspender by screw thread conehead axle 1, expanding sheath 2, fastening nut 3, spring 4, location cover 5, suspension ring 6 form, and it is characterized in that screw thread is arranged at the top of screw thread conehead axle 1, the bottom is a conical head 1.1, the top of conical head 1.1 is narrow, and the bottom is wide; Outside at described screw thread conehead axle 1 is with expanding sheath 2, described expanding sheath 2 tops are complete jacket casing shape, and the lower part is open tail end, be split up into 3 lobe expanding plates 2.1, axle center with screw thread conehead axle 1 is that center ring is around uniform, described expanding sheath 2 is when non-tensioning state, and size can be tucked into expanding sheath 2 the volume in-core of spool like this than the little 2.5-0.8mm of internal diameter of spool.

The open tail end of described expanding plate 2.1 is against conical head 1.1 middle parts of screw thread conehead axle 1, is provided with Skidproof structure at the outside face of described expanding plate 2.1, and described Skidproof structure is a dentation 2.2; Between expanding sheath 2 inside and the screw thread conehead axle 1 spring 4 is arranged; Be provided with the location and cover 5 outside expanding sheath 2, the location is covered 5 and can be stuck on the volume core end face of spool, realizes the location with this.The location is covered 5 and is provided with fastening nut 3, controls the lifting of screw thread conehead axle 1 with fastening nut 3; The top at screw thread conehead axle 1 is provided with suspension ring 6, in order to the lifting spool.

Described conical head 1.1 has cascaded surface with the axis body junction, is provided with backing plate 7 at the cascaded surface place.

Described spring 4 is arranged between expanding sheath 2 inside and the screw thread conehead axle 1, and one is against expanding sheath 2 inside, and one is against on the backing plate 7.

The working process of described expanding suspender is as described below: the volume in-core that expanding sheath 2 parts of the suspender of relaxed state is tucked into spool, cw turns fastening

nut

3,5 end faces that withstand the volume core of spool are covered in the location, pulling screw thread conehead axle 1 rises, conical head 1.1 is raised, three plate expanding plates, 2.1 expansions that are against the open tail end on the conical head 1.1 are come, then described expanding plate 2.1 is tightly withstood on the inwall of volume core, and dentation 2.2 increases friction force makes suspender can bear bigger lifting force.The finished product lifting can be transported to package post like this.Otherwise with the rotation of fastening nut 3 anticlockwise directions, conical head 1.1 descends, and three lobe expanding plates 2.1 shrink, and suspender can take out from the volume core.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
