3 is a schematic perspective view showing a cable guide device including a first belt member according to the present invention, and FIG. 4 is a schematic perspective view of a cable guide device including a first belt member according to the present invention except for a fixing part. Figure 5 is a schematic front view of a state except for the fixing part in the cable guide device including the first belt member according to the present invention.

3 to 5, the cable guide device 10 according to the present invention includes a plurality of belt members 100 and 100'; a first end-side fixing part 20 fastened to one side of the plurality of belt members 100 and 100'; and a second end-side fixing part 30 fastened to the other side of the plurality of belt members 100 and 100'.

Since the first end-side fixing part 20 and the second end-side fixing part 30 are obvious matters in the art, a detailed description thereof will be omitted.

At this time, the plurality of belt members (100, 100') is a first stage belt member 100; and a second stage belt member 100' located above the first stage belt member 100.

At this time, although the drawing shows that the plurality of belt members (100, 100') are composed of two stages, unlike this, the plurality of belt members (100, 100') may be composed of two or more stages, Therefore, in the present invention, the number of the plurality of belt members 100 and 100' is not limited.

On the other hand, the plurality of belt members (100, 100') are laminated in a first stage and a second stage. Therefore, in the present invention, the plurality of belt members (100, 100') are a plurality of belt members It can be defined as a “laminated belt member” that is laminated.

On the other hand, as in the above-described FIGS. 1 and 2, the first belt member according to the present invention corresponds to the first stage belt member 100 of FIGS. 3 to 5.

Therefore, the first stage belt member 100, as in the above-described FIGS. 1 and 2, the first belt member first unit body 110; a first belt member second unit 120 positioned adjacent to the first belt member first unit 110; And a third unit of the first belt member 130 positioned adjacent to the second unit of the belt member 120, and the first unit of the first belt member 110, the 1-1 body 111, and the second unit body 120 of the first belt member includes a first-second body portion 121, and the third unit body 130 of the first belt member includes the first-second unit body 120. 3 includes the body portion 131.

At this time, the multi-joint support member 40 may be inserted into the 1-1 body part 111, the 1-2 body part 121 and the 1-3 body part 131, and these various Since the joint support member is obvious in the art, a detailed description thereof will be omitted.

Meanwhile, the second-stage belt member 100' may also include each unit body in the same way as the first-stage belt member, and at this time, each unit body may include each body portion, as shown in FIGS. As shown in Fig. 5, the multi-joint support member 50 may be inserted into each body part, but, unlike this, for example, a wire cable, an optical fiber cable, a flexible cable or hose such as a fluid supply hose etc. can be inserted, which is obvious in the art, so a detailed description thereof will be omitted.

On the other hand, the first stage belt member 100 according to the present invention, as in the above-described FIGS. 1 and 2, the first reinforcing portion 150 located on the first side of the first stage belt member 100 ), wherein the first reinforcement part 150 includes a first reinforcement part body part 151, and the first reinforcement part body part 151 includes a plurality of concave parts and a plurality of pitch parts do.

At this time, in the present invention, as shown in FIGS. 3 to 5, each body part of each unit body of the second stage belt member 100' is disposed in the plurality of recesses.

As described above, in the case of a general cable guide device, the drive of the cable guide device causes friction between the plurality of belt members, and the friction causes the plurality of belt members to wear out. .

Due to wear of the belt member, dust is generated, and this dust acts as an impurity in the environment in which the cable guide device is used.

However, in the present invention, for example, the first stage belt member 100 includes a plurality of concave first reinforcing portion body parts 151, and each unit of the second stage belt member 100' By disposing each of the body parts in the plurality of concave portions, it is possible to maximize a contact area between the first stage belt member and the second stage belt member.

Therefore, in the present invention, when the cable guide device is driven, the first stage belt member and the second stage belt member can be driven in a state in which they are fixed in close contact as much as possible, so that the first stage belt member and the second stage belt member can be driven. By minimizing friction between the belt members, it is possible to minimize generation of dust due to abrasion of the plurality of belt members.

In addition, in the present invention, generation of dust can be minimized through the structural features as described above, as well as generation of dust can be minimized through the material of the belt member.
