Hereinafter, a cable winding apparatus A according to the present invention will be described in detail with reference to the accompanying drawings.

The cable winding apparatus A according to the present invention comprises a housing 10 provided with a cable outlet 11, a bobbin 20 fixed to the housing 10 at both ends and wound with a cable C, (30) provided on the side of the main body (11).

As shown in Fig. 1, the outlet 11 is a passage through which the cable C travels. It is also possible to confirm that the cable C is provided with the limiting member S for limiting the degree of pull-in.

2 and 3, the draw-out holding means 30 includes a frame 31 having a through hole 311 through which the cable C passes, a frame 31 coupled to one end of the frame 31, A lift 35 coupled to the other end of the frame 31 and having a coupling portion 351 at the bottom and a bobbin 20 positioned between the housing 10 and the bobbin 20 One end of which is coupled to the rotation shaft of the bobbin 20 and the other end of which is coupled to the engagement portion 351 of the lift 35.

The frame 31 has a through hole 311 to allow the cable C to pass therethrough together with the outflow port 11 described above. That is, the cable C is inserted or drawn out through the through-hole 11 and the through-hole 311 of the frame 31.

The frame 31 rotates about the pivot shaft 33 through the pivot shaft 33. This operating characteristic is obtained by reducing the angle between the pintle 11 and the through hole 311 so that the cable C Let it fit between the two.

The lift 35 is connected to the belt member 37 and serves to rotate the frame 31 about the pivot 33 as soon as the cable C is switched to the winding or unclamping operation.

3, the belt member 37 is provided with a plurality of friction protrusions 371. As shown in Fig.

Now, referring to FIG. 3, description will be made of an embodiment of the present invention having such a structure.

The cable C is drawn out through the through hole 311 of the frame 31 when the cable C wound around the bobbin 20 is pulled out in the process of unwinding the cable C. At this time, The tension is released and the through hole 311 and the outlet 11 are parallel to each other so that the cable C is easily drawn out to the outlet 11.

When the pulling of the cable C is stopped by stopping the external force applied to the cable C in the next step, tension is momentarily applied to the belt member 37 so that the belt member 37 pulls the lift 35 inward. The frame 31 is rotated by one end (clockwise in FIG. 3) about the pivot 33 as the one end is fixed by the pivot 33. When the frame 31 is rotated through this process, the through hole 311 of the frame 31 and the outflow port 11 are not parallel to each other and the outer surface of the cable C is inserted into the through hole 311 of the frame 31 So that it can no longer move (see the lower circle area in Fig. 3)

In order to enhance the operating characteristics of the 'draw-out operation', friction enhancing means (not shown) may be provided around the through-hole 311.

When the pull-out holding state is to be released, the tension of the belt member 37 is released and the cable C can be pulled out or pulled in again by pulling out the cable C lightly.

On the other hand, in FIGS. 2 and 3, the operation of the handle 40 according to the present invention can be confirmed.

According to the first embodiment shown in Figs. 2 and 3, the housing 10 is provided on one side and includes a handle mounting portion 13 having a fixing portion 131 and a penetration portion 133,

The cable retractor A has a fixing hole 41 formed at an end portion thereof to engage with the fixing portion 131 and has a handle 40 which is exposed to the outside of the housing 10 through the penetrating portion 133 And further comprising:

Particularly, the fixing hole 41 is formed as a long hole to provide fluidity to the fixing engagement of the housing 10 of the handle 40, so that when the cable winding device A is stored, the exposed handle 40 is fixed to the outer surface of the housing 10 So that it can be stored with a clean appearance.

In addition, the handle is preferably made of a resilient material in order to provide fluidity to the fastening of the housing (10) of the handle (40).

The structure of the handle 40 is integrally formed, and the structure of the handle 40 is simplified, thereby reducing the product cost and reducing the number of components, thereby reducing the probability of occurrence of defects.

The second embodiment of the present invention will be described in more detail with reference to FIG.

The second embodiment of the present invention is characterized in that in the coupling between the first cover 10A and the second cover 10B constituting the housing 10, the sealing means 60 is provided to improve the waterproof property, So as to contribute to the durability of the product.

4, the housing 10 comprises a first cover 10A and a second cover 10B which are coupled to each other. The first cover 10A has a coupling protrusion 61 And the second cover 10B is formed with a coupling groove 62 at the coupling portion and the coupling projection 61 is inserted into the coupling groove 62 so that the first cover 10A and the second cover 10B.

The coupling protrusions 61 are formed of first and second coupling protrusions 611 and 612. The first coupling protrusions 611 are shorter than the second coupling protrusions 612, The characteristics related to the sealing member 63 (to be described later) will be described below again.

4, the sealing means 60 further comprises a sealing member 63 arranged between the engaging projections 61 and the engaging grooves 62 and having an expanding member 630 therein .

Here, the expansion member 630 is preferably a solid or gel state material that expands in volume by heat, and when the temperature rises due to heat transmitted from the heat generating member 64, the volume expands, The inside of the coupling groove 62 is closed, and when the temperature is lowered after the supply of power is finished, the volume is reduced to release the sealing of the coupling groove 62 (see Fig.

The characteristic that the first coupling protrusions 611 are shorter than the second coupling protrusions 612 and that the expansion member 630 is provided inside the hermetically closed means 93 is one of the key features of the present invention The effects of these characteristics will be described below.

The expansion member 630 is contracted in a normal state in which no power is applied, and the empty space is increased inside the coupling groove 62 in the state shown in the upper circular region of FIG.

At this time, the engaging groove 62 and the engaging projection 61 can be easily engaged and disengaged, so that the user can easily separate the first cover 10A and the second cover 10B.

However, when power is supplied, heat is generated in the heat generating member 64 provided inside the coupling groove 62, and this heat heats the expanding member 630.

The volume of the expansion member 630 heated by the heat transferred from the heat generating member 64 expands and the sealing member 63 fills the inner space of the coupling groove 62 to completely seal the inside of the coupling groove 62. (See inside the lower circle area in Fig. 4)

At this time, the 'characteristic of the first coupling protrusion 611 shorter than the second coupling protrusion 612' is a very important factor,

Since the first engaging projection 611 is shorter than the second engaging projection 612, the outer side of the inner space of the engaging groove 62 provided with the first engaging projection 611 is provided with the second engaging projection 612 It has more clearance than the inner side,

So that the first cover 10A and the second cover 10B can be separated from each other even in the heating state in which the sealing is performed.

If it is impossible to disconnect the housing 10 while the power is being supplied, if the opening of the housing 10 is required due to an accident that occurs suddenly, it is necessary to stop the power supply and wait until it is cooled to some extent. The first coupling protrusion 611 has a shorter characteristic than the second coupling protrusion 612, and the housing 10 (see FIG. 10) ) Is very important.

Although a detailed description of the known technology relating to the expanding member 630 has been omitted from the detailed description of the present invention, it is understood that a person skilled in the art can understand and infer that the expanding member 630 can be practiced.
