Technical Field

[0001] The invention relates to the technical field of power cable installation, and in particular to a cable protection tube that is convenient for threading. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In order to prevent cable fires and reduce the scope of cable fires and minimize the losses caused by cable fires, when laying cables, the cables from the cable trench to the electrical equipment must be inserted into cable protection tubes to protect the cables.

[0004] When the cable is passed through the pipe, one end of the cable needs to be passed through the protective pipe. When the cable is long, it takes a long time and is inconvenient to operate. Moreover, when multiple cables need to be laid inside a protective pipe, the cables are easily entangled with each other, hindering the insertion of subsequent cables. Summary of the invention

[0005] The purpose of the present invention is to provide a cable protection tube that is convenient for threading the cables, thereby facilitating the threading of the cables and reducing the entanglement of the cables.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: a cable protection tube that is convenient for threading, comprising:

[0007] A tube body, wherein the interior of the tube body is hollow, and the side of the tube body is provided with at least one wire release opening for allowing the cable to move from the side of the tube body into the interior of the tube body;

[0008] The separator is rotatably arranged inside the tube body, and is used to divide the inside of the tube body into a plurality of cable placement areas, and to block each cable release opening after the cables are placed therein.

[0009] Furthermore, the number of the wire-releasing openings is not less than two, and the plurality of wire-releasing openings divide the tube body into a plurality of first arc-shaped tube segments. A first cylinder located at the axis of the plurality of first arc-shaped tube segments is provided at one end of the tube body, and a first connecting rod is provided between the first cylinder and each first arc-shaped tube segment.

[0010] Furthermore, the separator includes a second cylinder, on which connecting plates corresponding to the number of the wire-releasing openings are arranged, and an end of the connecting plate away from the second cylinder is provided with a second arc-shaped pipe segment for sealing the wire-releasing opening and abutting against the inner wall of the first arc-shaped pipe segment.

[0011] Furthermore, a positioning pin is provided at one end of the second cylinder, and a positioning groove for the positioning pin to be inserted into is provided on the first cylinder. After the positioning pin is inserted into the positioning groove, the first cylinder can rotate around the second cylinder.

[0012] Furthermore, an arc-shaped paddle is provided at one end of the second arc-shaped tube segment away from the positioning pin, the cross section of the arc-shaped paddle is T-shaped, and the arc-shaped paddle is composed of a transverse section and a vertical section, wherein the vertical section is connected to the second arc-shaped tube segment, and the transverse section is provided at one end of the vertical section away from the second arc-shaped tube segment;

[0013] After the positioning pin is inserted into the positioning groove, the vertical section abuts against the outer wall of the first arc-shaped pipe segment. The first arc-shaped pipe segment is provided with a stopper located in the rotation area of ​​the vertical section. When the vertical section abuts against the stopper, the wire release opening is blocked by the second arc-shaped pipe segment.

[0014] Furthermore, the first arc-shaped tube segment is provided with an arc-shaped strip at one end close to the first cylinder, and when the vertical section abuts against the stopper, the arc-shaped strip can be inserted between two adjacent arc-shaped strips of another cable protection tube, and the two adjacent arc-shaped strips of another cable protection tube are both located within the rotation area of ​​the arc-shaped strip;

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-8 The present invention discloses a cable protection tube which is convenient for threading, comprising:

[0033] The tube body 1 is hollow inside and has at least one cable release opening on the side of the tube body 1 for allowing cables to move from the side of the tube body 1 into the inside of the tube body 1;

[0034] The separator 2 is rotatably disposed inside the tube body 1 and is used to divide the inside of the tube body 1 into a plurality of cable placement areas and to seal each cable release opening after the cables are placed therein.

[0035] The present invention opens a wire-releasing opening on the side of the tube body 1 so that the cable to be protected can be directly placed into the tube body 1 from the wire-releasing opening, thereby saving the time for threading. Meanwhile, after the cable has been connected, it can still be connected to the tube body 1, so that the cable protection tube is not only suitable for the protection of newly installed cables, but also can be subsequently installed for existing cables, thus having a wider range of uses. By setting the separator 2, different cables can be placed in the multiple cable placement areas inside the tube body 1, thus reducing the entanglement of the cables. After the cables have been placed, the wire-releasing opening can be sealed by the separator 2 to prevent the installed cables from being removed.

[0036] In one embodiment, the number of pay-off openings is not less than two, and the plurality of pay-off openings divide the tube body 1 into a plurality of first arc-shaped tube segments 11. A first cylinder 12 located at the axis of the plurality of first arc-shaped tube segments 11 is disposed at one end of the tube body 1, and a first connecting rod 13 is disposed between the first cylinder 12 and each first arc-shaped tube segment 11.

[0037] This design allows cables placed in different cable placement areas to enter from different cable release ports, avoiding the situation where cables are placed in a chaotic manner. The cable release ports divide the pipe body 1 into multiple independent first arc-shaped pipe segments 11, and the first cylinders 12 and multiple first connecting rods 13 are used to connect the first arc-shaped pipe segments 11, so that the divided pipe body 1 remains as a whole, which is convenient for subsequent installation and debugging.

[0038] In one embodiment, the separator 2 includes a second cylinder 21, on which connecting plates 22 corresponding to the number of wire-releasing openings are provided, and the connecting plate 22 is provided with a second arc-shaped pipe segment 23 for sealing the wire-releasing opening and abutting against the inner wall of the first arc-shaped pipe segment 11 at one end away from the second cylinder 21.

[0039] With such a design, when the separator 2 is installed in the tube body 1, the interior of the tube body 1 is divided into a plurality of independent cable placement areas due to the blocking effect of the connecting plates 22, so that the cables placed in each cable placement area will not enter the remaining cable placement areas in the subsequent process, effectively ensuring that each cable is located in the set cable placement area. At the same time, because the second arc-shaped tube segment 23 abuts against the inner wall of the first arc-shaped tube segment 11, when the second arc-shaped tube segment 23 rotates to the wire-releasing port, the wire-releasing port can be blocked, and when the second arc-shaped tube segment 23 rotates to the non-wire-releasing port area, the cable can normally pass through the wire-releasing port into the corresponding cable placement area.

[0040] In one embodiment, a locating pin 24 is provided at one end of the second cylinder 21, and a locating groove for the locating pin 24 to be inserted into is opened on the first cylinder 12. The cross-sections of the locating pin 24 and the locating groove are both T-shaped, and the diameter of the end of the locating pin 24 away from the second cylinder 21 is larger than the diameter of the end close to the second cylinder 21. The minimum inner diameter of the locating groove is smaller than the maximum outer diameter of the locating pin 24. The locating pin 24 can be slightly deformed by an external force and then pass through the minimum inner diameter section of the locating groove and be inserted into the locating groove, so that after the tube body 1 and the separator 2 are spliced ​​with the locating pin 24 and the locating groove, they can still rotate freely while keeping the axial distance unchanged.

[0041] In one embodiment, an arc-shaped paddle 25 is provided at one end of the second arc-shaped tube segment 23 away from the positioning pin 24, the cross section of the arc-shaped paddle 25 is T-shaped, and the arc-shaped paddle 25 is composed of a transverse section and a vertical section, wherein the vertical section is connected to the second arc-shaped tube segment 23, and the transverse section is provided at one end of the vertical section away from the second arc-shaped tube segment 23;

[0042] After the positioning pin 24 is inserted into the positioning groove, the vertical section abuts against the outer wall of the first arc-shaped pipe segment 11. The first arc-shaped pipe segment 11 is provided with a stopper 14 located in the rotation area of ​​the vertical section. When the vertical section abuts against the stopper 14, the wire release opening is blocked by the second arc-shaped pipe segment 23.

[0043] By such a design, after the tube body 1 and the separator 2 are assembled, the arcuate paddle 25 can be in a position that is convenient for human hand to hold, so that the installer can adjust the rotation angle between the tube body 1 and the separator 2 by holding the tube body 1 with one hand and the arcuate paddle 25 with the other hand. By setting the stop block 14, it can cooperate with the arcuate paddle 25. After the separator 2 has finished covering the wire-releasing opening, the obstruction effect of the stop block 14 is used to remind the installer that the tube body 1 and the separator 2 have been rotated into place.

[0044] In one embodiment, an arc-shaped strip 15 is provided at one end of the first arc-shaped tube segment 11 close to the first cylinder 12, and when the vertical section abuts against the stopper 14, the arc-shaped pick 25 can be inserted between two adjacent arc-shaped strips 15 of another cable protection tube, and the two adjacent arc-shaped strips 15 of another cable protection tube are both located within the rotation area of ​​the arc-shaped pick 25;

[0045] The arc-shaped pick 25 is provided with a screw installation hole, and the second arc-shaped tube piece 23 is provided with a screw installation groove, which is used for connecting and fixing the two cable protection tubes by inserting screws into the screw installation hole and the screw installation groove when the two cable protection tubes are spliced.

[0046] Such a design allows two adjacent installed cable protection tubes to be close to each other, so that the arc-shaped paddle 25 of one cable protection tube is inserted between the two arc-shaped bars 15 of the other cable protection tube, and then the screws are passed through the screw mounting holes and inserted into the screw mounting grooves to fix them, so that the two adjacent cable protection tubes are in a whole and can rotate and move axially synchronously, and the tube body 1 and separator 2 of each cable protection tube cannot rotate independently due to the cooperation of the arc-shaped paddle 25 and the arc-shaped bar 15, so that the wire-releasing opening of the assembled cable protection tube will not be opened at will.

[0047] In one embodiment, the cable protection tube also includes an end locator 3, which consists of a third cylinder 31, a plurality of arc-shaped positioning blocks 32 that can be inserted between two adjacent arc-shaped strips 15, and a second connecting rod 33 connecting the third cylinder 31 and each arc-shaped positioning block 32, and the arc-shaped positioning block 32 is provided with a screw mounting hole corresponding to the screw mounting groove.

[0048] With such a design, after all the cable protection tubes are assembled, the end locator 3 is installed on the tube body 1 at the end of the cable protection tube, and then it is fixed by screws through the screw mounting holes and screw mounting grooves, so that the unrestricted tube body 1 at the end is restricted by the end locator 3 and forms a whole with the corresponding separator 2, ensuring that the cable protection tube will not rotate independently at any part after assembly.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
