A take-up box of a pull rope for pulling an object convenient to use and attractive in appearance, without removing during nuclear magnetism inspection. The take-up box comprises a pull rope, a wire box base, a fixing ring, and a rubber sleeve. The wire box base, the fixing ring, the rubber sleeve and the braided pull rope which are all made of plastic materials are adopted, and when the take-up box is used on a human body rehabilitation tool, a wearer does not need to take off the take-up box when doing related medical examination. By adopting the soft turnable rubber sleeve, the take-up box is attractive in appearance, and an overlong rope part can be conveniently wound in the take-up box. The hook surface of a magic tape is fused and fixed on the bottom surface of the wire box base by means of the hot-melting process, so that the take-up box can be conveniently adhered to a selected position on the rough surface of the magic tape provided on the human body rehabilitation tool.

Description

Draw-up box of drawstring used for pulling objects

Technical field

The utility model relates to an accessory for a drawstring used for pulling objects, in particular to a wire take-up box for a drawstring used for human body protection appliances.

Background technique

In many occasions in real life, draw ropes are used. The length of the draw rope can be stored in the draw-up box through the draw-up box set at one end of the draw rope, usually by winding the excess length of the rope. On the spool set on the take-up box.

The spool in the prior art may have an exposed structure or a hidden structure. The exposed design is simple in structure but ugly in appearance. The concealed setting structure usually has an elastic rebound part in the wire take-up box, and the extra length of the cord can be automatically wound in the wire take-up box by activating the elastic rebound member. Although this structure is convenient to use, the internal structure of the wire take-up box is complicated, the cost is high, and the resilience function of the elastic resilience component is reduced due to a long use time.

When using a drawstring to fasten or tighten an object being pulled, the outer end of the drawstring is usually tied with a column or the wire take-up box so as to be hand-held.

The shortcomings of the above structure are as follows: 1) The column or the wire receiving box is mostly doped with some metal parts, so when the drawstring is used on the human body rehabilitation equipment, it is not conducive to medical examinations, such as nuclear magnetic resonance examinations. At the time, all metal fittings need to be removed. 2) When the drawstring is too long, it is inconvenient to store or unsightly after storage.

technical problem

The best mode of the present invention

The wire take-up box 5 of the draw rope 4 used for pulling objects of the present invention is suitable for various situations of pulling or tightening objects, that is, one end of the draw rope 4 is tied to the object being pulled, and the other end of the draw rope 4 It is fixedly connected in a wire take-up box 5 that is easy to hold by hand, and an overly long drawstring 4 can be wound on a reel arranged in the wire take-up box 5.

As shown in FIGS. 1 and 2, the wire take-up box 5 is composed of a wire box base 1, a fixing ring 2 and a rubber sleeve 3.

1. Wire box base 1.

It is made of plastic material. It has a seat 11 and a handle 12 (also called a handle). The center of the seat 11 is provided with a circular hole. The periphery of the circular hole is an upwardly extending shaft cylinder 111. The shaft cylinder 111 is provided with a plurality of buckle holes 112 and a rope hole 113 for fixing the rope head at intervals.

An annular sleeve groove 114 is also provided on the seat 11 at the periphery of the buckle hole 112 and the buckle hole 113.

In order to facilitate the user to hold the wire take-up box 5, an anti-skid pad 121 made of silicone material is provided on the handle portion 12, and at the same time, an anti-skid scratch line 122 is provided on the bottom surface of the wire box base 1 corresponding to the handle portion 12.

The lead-out end of the pull cord 4 extends from the outlet hole 13 provided on the cable box base 1. The outlet hole 13 is located on the side opposite to the handle. The outlet angle of the pull cord 4 through the outlet hole 13 is 90 degrees, that is The direction of the pull rope 4 at the outlet hole 13 changes from the horizontal direction to the vertical direction and then to the horizontal direction. This structure is beneficial to increase the friction force and reduce the force of the fixing ring 2, which is convenient to use and has a beautiful appearance.

When the wire take-up box 5 of the present invention is applied to a waist protection belt that protects the waist of the human body, the shape of the bottom surface of the wire box base 1 can be designed as an arc surface that matches the curvature of the waist.

At the same time, the hook surface 123 of velcro is provided on the bottom surface of the wire box base 1, which is beneficial to the time when the waist protection belt is tightened, the wire take-up box 5 can be glued and fixed on the outer surface of the waist protection belt. Paste on the rough surface (see Figure 5).

The drawstring 4 used in the take-up box 5 of the present invention is a braided rope, and the surface of the drawstring 4 is provided with a coating that can reduce friction.

2. Fixed ring 2.

As shown in Figure 3, it is made of plastic material, and its shape is a cylinder with open ends. On the bottom surface of the fixed ring 2 there are a plurality of clamping blocks 21 and a rope end that can hold the drawstring 4 at intervals along its periphery. The cord-inserted buckle 22 fastened in the rope hole 113, each block 21 can be clamped and fixed in a corresponding one of the buckle holes 112, and the rope-inlaid buckle 22 can be clamped and fixed in In the rope hole 113, the fixing ring 2 can be fastened to the wire box base 1 in a manner of being buckled on the shaft cylinder 111.

3. Rubber sleeve 3.

The rubber sleeve 3 is made of elastic rubber, preferably TPE (also called thermoplastic elastomer soft rubber), which is a stepped cylindrical shape, which is the lower small diameter sleeve 31 and the upper large diameter sleeve 32, respectively. A convex ring convex radially outward is provided at the bottom of the, and the part between the convex ring and the top of the small-diameter sleeve 31 is called an annular recess 33. The fixed ring 2 is sleeved on the small-diameter sleeve 31, and the fixed ring The ring part of 2 is clamped and embedded in the annular recess 33 (see Figure 4).

A transition platform 34 is provided between the large-diameter sleeve 32 and the small-diameter sleeve 31, and the large-diameter sleeve 32 can be turned down 180 degrees and covered on the wire box base 1. The utility model has the following advantages: 1) All parts of the entire product use plastic materials, and no metal parts are used. When the user wears normally, he can perform various medical device inspections without removing the wire receiving box 5. 2) Between the elastomer rubber sleeve 3 and the wire box base 1, a fixed buckle is designed (that is, the rope inlay buckle 22 and the rope hole 113 of the matching structure, and the buckle 21 and the buckle hole 112 of the matching structure). By pressing the rope head, the rubber sleeve 3 can also be clamped at the same time, so that the rubber sleeve 3 is not separated from the base 1 of the wire box.

The method of use of the utility model: 1) Turn the large-diameter sleeve 32 on the rubber sleeve 3 upwards, and then insert the fixed ring 2 into the annular recess 33 on the small-diameter sleeve 31. 2) Tie the end of the drawstring 4 and place the end of the rope between the rope buckle 22 on the fixing ring 2 and the rope hole 113 on the base 1 of the cable box. At the same time, the clamp on the fixing ring 2 21 is also opposite to a buckle hole 112 on the base 1 of the wire box. 3) Press the fixing ring 2 down and fix it on the base 1 of the wire box, and at the same time, connect the rubber sleeve 3 to the base 1 of the wire box. 4) Wrap the excessively long drawstring 4 partly on the outer wall of the ring part of the fixed ring 2, and other parts of the drawstring 4 are led out from the outlet hole 13 described above. 5) Turn the large-diameter sleeve 32 of the rubber sleeve 3 downwards by 180 degrees to close all the structures in the cable box base 1. At this time, the bottom edge of the large-diameter sleeve 32 is just inserted into the In this way, the envelope groove 114 can be dust-proof and moisture-proof.
