Description

Opening tool for cable protection tube

The present invention relates to the technical field of cable protective tubes, and particularly relates to an opening tool for cable protective tubes.

Generally, large-scale machinery must be equipped with several cables to supply power to the large-scale machinery. In order to prevent these cables from being exposed, the cables must be bundled in a cable as disclosed in the Republic of China Patent Publication No. I609140B In the wire protection tube, to prevent the cables from being exposed and damaged.

When a large machine is in operation, the cable will be displaced in accordance with the processing action of the large machine; when a large machine is processing, it is easy to drop debris, and when the debris falls into the chain structure of the cable protection tube, it is easy to scratch The cables installed inside cause the cables to break and leak electricity. Therefore, it is not only necessary to open the cable protection tube from time to time to remove debris, but also to open the cable protection tube to replace the cable.

In order to clean the inside of the cable protection tube or replace the damaged cable, the maintenance personnel must remove the cable protection tube chain from time to time. Personnel usually use pliers or open it directly with their hands. However, the aforementioned opening method is inconvenient and often causes difficulties in operation.

In view of this, it is indeed necessary to provide a technical solution to solve the problem of difficulty in opening the chain piece of the cable protection tube.

The purpose of the present invention is to solve the problem of difficulty in opening the chain piece of the cable protection tube.

In order to solve the aforementioned problems, the present invention is an opening tool for a cable protective tube, comprising: a sliding part having a bottom surface, a top surface, and a guide groove recessed from the bottom surface, the guide groove being along the A guiding direction extends, the top surface has a first end surface and a second end surface opposite in the guiding direction, the top surface is inclined from the first end surface to the second end surface, and the first end surface extends to The bottom surface is a first distance, the second end surface extends to the bottom surface is a second distance, the first distance is smaller than the second distance; a holding part is connected to the top surface.

In a preferred embodiment, the holding portion is cylindrical, and one end surface of the holding portion is connected to the top surface.

In a preferred embodiment, the sliding portion further has a joint surface connected to the bottom surface, the joint surface is connected to the first end surface, and a lead angle is sandwiched between the joint surface and the bottom surface.

In a preferred embodiment, the opening tool of the cable protection tube further has a guiding portion connected to the top surface, and the guiding portion is located on the second end surface and has an inclined surface connected to the top surface and connected to the top surface. A guiding surface of the inclined surface, an inclined angle is sandwiched between the guiding surface and the inclined surface.

In a preferred embodiment, there is an obtuse angle between the inclined surface and the top surface.

The opening tool of the cable protection tube of the present invention allows the guide groove to be embedded in the side plate of the cable protection tube, so that the opening tool can continuously move along the guiding direction of the side plate, so that the opening tool can be removed and touched along the way. The chain piece of the guide surface springs apart by the guide chain piece of the guide surface, so that the opening tool can move more smoothly along the guide direction of the side plate, achieving the effect of quickly disassembling the chain piece.

Please refer to Figures 1 to 3, the present invention is a cable protective tube opening tool, mainly having a sliding portion 10 and a gripping portion 20, wherein: the sliding portion 10 has a bottom surface 11, a top surface 12 , Two opposite side surfaces 16, and a guide groove 111 recessed from the bottom surface 11, the guide groove 111 extends along a guide direction X, and another There is a first end surface 14 and a second end surface 15 opposite in the guiding direction X. The top surface 12 is inclined along the guiding direction X. The closer to the first end surface 14, the top surface 12 and The shorter the distance between the bottom surfaces 11 and the closer to the second end surface 15, the longer the distance between the top surface 12 and the bottom surface 11; in this embodiment, the extension direction of the top surface 12 and the bottom surface The position where the extension items of 11 intersect is an acute angle θ2.

The holding portion 20 is cylindrical, and one end surface of the holding portion 20 is connected to the top surface 12.

In this embodiment, the sliding portion 10 further has a joint surface 13 connecting the bottom surface 11 and the first end surface 14, and there is a lead angle θ1 between the joint surface 13 and the bottom surface 11; The lead angle θ1 enables the opening tool to slide more smoothly on the side plate of the cable protection tube.

In particular, the top surface 12 has a first side 121 and a second side 122 connected along the guiding direction X. The first side 121 is closer to the first end surface 14 than the second side 122. The holding portion 20 and the guiding portion 30 are connected to the second end surface 122 of the top surface 12, and the guiding groove 111 penetrates the top surface 12 on the first side 121.

Secondly, the opening tool of the cable protection tube further has a guiding portion 30 connected to the top surface 12, the guiding portion 30 is located on the second side 122 and has an inclined surface 31 connected to the top surface 12, and connected to the top surface 12 The inclined surface 31 and the side surface 16 are inclined guiding surfaces 32, and the guiding surface 32 is located between the inclined surface 31 and the side surface 16.

Finally, there is an obtuse angle θ3 between the inclined surface 31 and the top surface 12, so that the top surface 12 and the inclined surface 31 are based on the bottom surface 11, and the inclined surface 31 has a greater slope than the top surface 12.

The above is the structural configuration and connection relationship of the present invention in a preferred embodiment. The use of the present invention and the effects it can produce are as follows: 4, the present invention is applicable to a cable protection tube 40, the cable protection tube 40 has a side plate 41, and a chain piece 42 clamped on the side plate 41, the guide groove of the sliding portion 10 111 is embedded in the side plate 41 so that the opening tool of the cable protection tube can slide along the side plate 41.

Please refer to FIG. 5, the top surface 12 of the opening tool of the cable protection tube abuts against the chain piece 42, holding the grip 20 and pushing the opening tool of the cable protection tube in the extending direction of the side plate 41, because The closer the top surface 12 is to the second end surface 15, the farther the distance between the top surface 12 and the bottom surface 11 is, and the chain piece 42 is pushed apart by the top surface 12.

Referring to FIG. 6, after one end of the chain piece 42 is separated from the side plate 41, the opening tool of the cable protection tube is continuously pushed so that the chain piece 42 abuts against the inclined surface 31 of the guiding portion 30, due to the guiding portion The inclined surface 31 of 30 is more inclined than the top surface 12, so the chain piece 42 will be guided by the inclined surface 31 to continue to open.

7 and 8, continue to push the opening tool of the cable protection tube to make the chain piece 42 contact the guide surface 32 and be guided, so that the chain piece 42 is fully opened to allow the cable protection pipe The opening tool can move towards the next chain piece 42; while the opening tool of the cable protection tube is inserted into the side plate 41 of the cable sheath through the guide groove 111, so that the opening tool can continue along the side plate 41 of the cable protection tube 40 Move and remove the chain piece 42 that comes into contact along the way.
