Description

Technical Field

[0001] The utility model relates to the technical field of PVC wire tubes, in particular to an insulating PVC wire tube. Background Art

[0002] Wires refer to conductors that transmit electrical energy, and are divided into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulation layer, and include copper and aluminum flat wires, overhead stranded wires, and various profiles. They are mainly used for outdoor overhead and indoor buses and switch boxes. When pre-burying wires during the decoration process, the wires need to be passed through wire tubes for construction to facilitate replacement and maintenance.

[0003] A Chinese patent discloses a PVC wire tube (authorization announcement number CN206075923U). The patented technology can achieve the goal of separating different types of wires by setting a herringbone dividing plate in the tube body, thereby facilitating the identification and replacement of wires.

[0004] With regard to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the partition plate inside the existing PVC wire pipe is integrated with the PVC wire pipe. When the number of wires to be wired exceeds the number of spaces separated by the partition plate, multiple wires need to be passed through one space, which can easily cause entanglement and affect the subsequent wire extraction, replacement or maintenance. Utility Model Content

[0005] The technical problem to be solved by the utility model is that: the existing technology has the disadvantage that the partition plate cannot be replaced according to needs, so we propose an insulating PVC wire tube.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an insulating PVC wire pipe, including an insulating wire pipe body, the interior of the insulating wire pipe body is slidably connected with a space dividing plate, the insulating wire pipe body is composed of a shaping layer and an insulating layer, the inner wall of the shaping layer is glued to the outer surface of the insulating layer, and the space dividing plate is composed of a guide layer and a flame retardant layer, the inner wall of the guide layer is glued to the outer surface of the flame retardant layer.

[0007] Preferably, a guide rail is provided inside the insulating wire tube body, and a limit strip is fixedly connected to the surface of the space dividing plate.

[0008] Preferably, the space dividing plate is in a honeycomb shape.

[0009] Preferably, the material of the shaping layer is plastic PVC.

[0010] Preferably, the insulating layer is made of insulating rubber.

[0011] Preferably, the guide layer is made of polyethylene.

[0012] Preferably, the flame retardant layer is made of PC.

[0013] Technical effects and advantages of the utility model:

[0014] In the utility model, the user inserts the space dividing plate from one end of the insulating wire tube body, and passes the wires separately from different spaces inside the space dividing plate. The wires are separated into different areas under the action of the space dividing plate, so that multiple wires are prevented from being entangled in the same space, which makes it inconvenient to pull out the wires for later maintenance. After the wires are passed through, the insulating wire tube body is laid according to the position where the wires need to be laid. By arranging the space dividing plate to be detachable, the user can choose whether to use the space dividing plate according to the situation of the wires, and can also choose dividing plates with different numbers of spaces according to the number of wires.

[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5As shown, the utility model provides a technical solution: an insulated PVC wire tube, comprising an insulated wire tube body 1, a space separator 2 is slidably connected inside the insulated wire tube body 1, the insulated wire tube body 1 is composed of a shaping layer 101 and an insulating layer 102, the inner wall of the shaping layer 101 is glued to the outer surface of the insulating layer 102, the space separator 2 is composed of a guide layer 201 and a flame retardant layer 202, the inner wall of the guide layer 201 is glued to the outer surface of the flame retardant layer 202, the user inserts the space separator 2 from one end of the insulated wire tube body 1, and inserts the wires from different spaces inside the space separator 2 separately, and the wires are separated into different areas under the action of the space separator 2 to prevent multiple wires from being entangled in the same space, which is inconvenient to pull out for later maintenance, and after the wires are inserted, the insulated wire tube body 1 is laid according to the required wiring position, and by setting the space separator 2 to be detachable, it is convenient for the user to choose whether to use the space separator 2 according to the situation of the wires, and can also choose separators 2 with different numbers of spaces according to the number of wires.

[0023] Reference Figure 2 As shown, in this embodiment: a guide rail 3 is opened inside the insulating wire tube body 1, and a limit bar 4 is fixedly connected to the surface of the space dividing plate 2. The user aligns the limit bar 4 with the position of the guide rail 3 and inserts the space dividing plate 2 into the insulating wire tube body 1. Under the action of the guide rail 3 and the limit bar 4, the space dividing plate 2 is prevented from rotating inside the insulating wire tube body 1 during the threading process, which causes inconvenience in threading.

[0024] Reference Figure 2 As shown, in this embodiment: the shape of the space dividing plate 2 is a honeycomb. By arranging the interior of the space dividing plate 2 in a honeycomb shape, the interior of the space dividing plate 2 is divided into multiple spaces. According to the number of wires and the specifications of the insulating wire tube body 1, space dividing plates 2 with corresponding specifications and different numbers of partitions can be selected to prevent the user from getting entangled in the wires due to multiple wires sharing the same tube when threading the wires.

[0025] Reference Figure 4 and Figure 5 As shown, in this embodiment: the material of the shaping layer 101 is plastic PVC. Polyvinyl chloride is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. It is an amorphous polymer containing a small amount of crystalline structure. The PVC can be shaped by heating. By using PVC material, the wire tube can be bent according to the needs of the line.

[0026] Reference Figure 4 and Figure 5As shown, in this embodiment: the material of the insulating layer 102 is insulating rubber. By gluing the insulating rubber on the inner wall of the plastic layer 101, the insulation of the PVC wire pipe can be better. At the same time, the rubber has strong wear resistance and a long service life, which can effectively avoid the danger caused by line aging.

[0027] Reference Figure 4 and Figure 5 As shown, in this embodiment: the material of the guide layer 201 is polyethylene, which has a certain hardness and toughness, and can make the space separator 2 bend along with the shape of the insulating wire tube body 1. At the same time, the hardness of the guide layer 201 prevents the internal space of the space separator 2 from being deformed due to extrusion, thereby ensuring a smooth threading process.

[0028] Reference Figure 4 and Figure 5 As shown, in this embodiment: the material of the flame retardant layer 202 is PC, which has both rigidity and toughness, high impact strength, high dimensional stability, a wide range of operating temperatures, good electrical insulation properties and heat resistance, and a flame retardant effect. By using PC material, fires caused by short circuits can be prevented.

[0029] The practical working principle of the present invention is as follows: the user inserts the space dividing plate 2 from one end of the insulating wire tube body 1, and separately passes the wires through different spaces inside the space dividing plate 2. Under the action of the space dividing plate 2, the wires are separated into different areas to prevent multiple wires from being entangled in the same space, which makes it inconvenient to pull out for later maintenance. After the wires are passed through, the insulating wire tube body 1 is laid according to the required wiring position. By setting the space dividing plate 2 to be detachable, the user can choose whether to use the space dividing plate 2 according to the situation of the wires, align the limit strip 4 with the position of the guide rail 3, and insert the space dividing plate 2 into the inside of the insulating wire tube body 1. Under the action of the guide rail 3 and the limit strip 4, the space dividing plate 2 is prevented from rotating inside the insulating wire tube body 1 during the threading process, which makes it inconvenient to thread the wires. By setting the interior of the space dividing plate 2 to be honeycomb-shaped, the interior of the space dividing plate 2 is divided into multiple spaces. According to the number of wires and the specifications of the insulating wire tube body 1, space dividing plates 2 with different corresponding specifications and number of compartments can be selected to prevent the user from rotating during the threading process. When multiple lines share the same pipe, wires are entangled. Polyvinyl chloride is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. It is an amorphous polymer containing a small amount of crystalline structure. PVC can be shaped by heating. By using PVC material, the wire pipe can be bent according to the needs of the line. By gluing and connecting insulating rubber on the inner wall of the shaping layer 101, the insulation of the PVC wire pipe can be better. At the same time, the rubber has strong wear resistance and a long service life, which can effectively avoid the danger caused by line aging. Polyethylene has a certain hardness and toughness, so that the space separator 2 can be bent following the shape of the insulating wire pipe body 1. At the same time, the hardness of the guide layer 201 prevents the internal space of the space separator 2 from being deformed due to extrusion. PC has both rigidity and toughness, high impact strength, high dimensional stability and a wide range of operating temperatures, good electrical insulation and heat resistance, and a flame retardant effect. By using PC material, fires caused by short circuits can be prevented.
