Reinforced PVC threading pipe

Abstract

The utility model discloses a reinforced PVC conduit. The reinforced PVC conduit comprises a conduit main body and a wrapping film. By adopting the color-changing temperature-measuring patch, the sealing block and the color powder, when the threading pipe main body is damaged by the outside, the threading pipe main body can be blocked to a certain extent through the metal ring, and if the blocking of the metal ring cannot achieve an effective effect, the sealing block can be damaged by external substances at the moment, so that the threading pipe main body is prevented from being damaged by the color-changing temperature-measuring patch. When the wiring harness is short-circuited or even broken, the color powder in the sealing block leaks out, the surface of the wiring pipe is dyed, subsequent personnel can quickly position the damaged position through the dyed area, and in addition, when the wiring harness is short-circuited or even broken, the damaged position can be quickly positioned. Due to the fact that the temperature of the corresponding position and the temperature of other surrounding areas are obviously changed due to the influence of the current, the position where the wire harness breaks down can be rapidly positioned through the color change of the color-changing temperature-measuring patch at the corresponding position, follow-up timely processing is facilitated, and the abnormity positioning effect is good.

Description

Technical Field

[0001] The utility model relates to the technical field of wire threading pipes, in particular to a reinforced PVC wire threading pipe. Background Art

[0002] The full name of the wire conduit is "insulated electrical conduit for construction". Generally speaking, it is a white hard PVC wire conduit that is anti-corrosion, anti-leakage, and used for threading wires. It is divided into plastic wire conduit, stainless steel wire conduit, and carbon steel wire conduit. It is used in normal indoor environments and in places with high temperature, dust, vibration, and fire hazards. It can also be used in humid places. It must not be used in particularly humid places, places with acid, alkali, salt corrosion, and explosion hazards.

[0003] The application number in the existing public technology is: CN202320580851.2 A high-pressure PVC threading tube. The high-pressure PVC threading tube includes a PVC tube body, the outside of the PVC tube body is provided with a pressure-resistant component for improving the pressure resistance of the PVC tube body, the inside of the PVC tube body is provided with a support component for supporting the PVC tube body, and the PVC tube body is provided with a storage component for accommodating the pressure-resistant component. The high-pressure PVC threading tube provided by the utility model enables the annular pressure-resistant ring and the reinforcement rod to form a cage-like structure through the connecting component, and the cage-like structure is stored in the storage component, which can protect the PVC tube body from pressure on the outside of the PVC tube body, effectively enhance the pressure resistance of the PVC tube body, and also support the PVC tube body inside the PVC tube body through the support component, which can not only facilitate the partitioning and placement of cables, but also support the PVC tube body to improve its overall structural strength.

[0004] However, the above patent still has certain disadvantages when in use: although the wires can be distinguished and placed through the space formed by the support blocks, the support spacing of the support blocks and the size of the space formed are fixed, which cannot well meet the placement and use of wires of different numbers or sizes, limiting the applicability of the threading tube. Moreover, the threading tube is generally long and the internal situation cannot be intuitively observed. When the wire is damaged or the threading tube itself is damaged, it takes a long time for personnel to locate the abnormality, which is time-consuming and labor-intensive to handle, and the overall use effect is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a reinforced PVC wire threading tube, which has the advantages of good abnormal positioning effect, adjustable threading space, and small wire harness interference, thereby solving the problems in the above-mentioned background technology.

[0008] (II) Technical solution

[0009] In order to achieve the above advantages of good abnormality positioning effect, adjustable threading space, and small wiring harness interference, the specific technical solutions adopted by the utility model are as follows:

[0010] A reinforced PVC threading tube comprises a threading tube body and a wrapping film, wherein a plurality of color-changing temperature measuring patches are attached around the outer surface of the threading tube body, the outer periphery of the color-changing temperature measuring patches is located on the surface of the threading tube body and is wrapped with a wrapping film, a plurality of sealing blocks are installed around one side of the inner surface of the threading tube body near the center of the threading tube body, and the inner position of the sealing blocks is filled with color powder.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a reinforced PVC threading tube, which has the following beneficial effects:

[0019] (1) The utility model adopts a color-changing temperature measuring patch, a sealing block, and a color powder. When the main body of the threading tube is damaged by the outside world, the metal ring can provide a certain degree of protection. If the blocking effect of the metal ring cannot be effective, the external substances will damage the sealing block. At this time, the color powder inside the sealing block will leak out, and then dye the surface of the threading tube. Subsequent personnel can quickly locate the damaged position through the dyed area. In addition, when the wiring harness is short-circuited or even broken, the temperature at the corresponding position will be significantly different from the temperature of other surrounding areas due to the influence of the current.

When multiple groups of wire harnesses need to be passed through, a corresponding number of support plates can be inserted into the docking grooves at different positions on the surface of the support columns according to the number and size of the wire harnesses. The space inside the wire threading tube body can be effectively divided by the arrangement of the support plates, so that different wire harnesses can be placed in different placement cavities, avoiding interference and entanglement between the wire harnesses, ensuring the effect of subsequent use, and having the advantages of adjustable threading space and small wire harness interference.

[0028] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] According to an embodiment of the utility model, a reinforced PVC threading pipe is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, a reinforced PVC threading tube according to an embodiment of the utility model includes a threading tube body 1 and a wrapping film 7, a plurality of groups of color-changing temperature measuring patches 6 are pasted around the outer surface of the threading tube body 1, and the outer periphery of the color-changing temperature measuring patches 6 is located on the surface of the threading tube body 1 and wrapped with a wrapping film 7, a plurality of groups of sealing blocks 2 are installed around one side of the inner surface of the threading tube body 1 near the center of the threading tube body 1, and the inner position of the sealing block 2 is filled with color powder 3, and the color powder 3 can be composed of different materials according to needs, such as high-pigment carbon powder or dye powder, etc., and any material with good adhesion and dyeing effect can be used.

[0031] In one embodiment, a support column 9 is provided at the center position inside the threading tube body 1, and a plurality of groups of docking grooves 4 are provided around the outer surface of the support column 9 and the inner surface of the threading tube body 1. Support plates 8 are clamped between the docking grooves 4, and placement cavities 10 are provided between the support plates 8. The placement cavities 10 are provided for placing the wiring harness. The structures such as the metal ring 5 and the sealing block 2 in the present application can be provided with corresponding grooves inside the threading tube after it is produced and then inserted and installed, followed by secondary hot-melt sealing, or other production processes can be used.

[0032] In one embodiment, a metal ring 5 is wrapped on one side of the inner surface of the threading tube body 1 away from the center of the threading tube body 1. The metal ring 5 is provided to enhance the overall strength of use and improve the supporting strength.

[0033] In one embodiment, the wrapping film 7 is made of transparent silicone material. The transparent silicone material is used to protect the color-changing temperature measuring patch 6 on the surface from damage by the outside world. On the other hand, the transparency makes it convenient for personnel to observe the color change of the color-changing temperature measuring patch 6, so as to locate the abnormality in time. The color-changing temperature measuring patch 6 can refer to the Changlong NCW3-75 reversible temperature measuring paper. The Changlong NCW3-75 reversible temperature measuring paper has unique color-changing temperature indication, digital display and reversible color change functions. It has a self-adhesive sticker. Once the temperature of the temperature monitoring part reaches or exceeds the rated temperature of the temperature measuring patch, the color-changing temperature measuring patch 6 immediately changes from black to red, and the over-temperature number is displayed on the temperature measuring patch. It is easy for people to find the temperature increase of the temperature monitoring part during the inspection, so as to find out the hidden dangers of faults and prevent accidents. If the temperature of the temperature monitoring part is too high, the temperature measuring patch will immediately change color due to over-temperature. After cooling down, the temperature measuring patch will immediately restore its original color and the patch can continue to be used.

[0034] In one embodiment, the support plate 8 is made of plastic material, which reduces the overall weight. In addition, personnel can also replace it with metal material as needed to increase the support strength. However, the use of metal material requires insulation treatment to avoid current transfer caused by wiring leakage.

[0035] In one embodiment, the support plate 8 is an I-shaped structure, which has good stress-bearing performance and structural characteristics. The cross-sectional shape of the I-shaped structure determines its bending deformation and axial stress when subjected to stress, thereby improving the overall strength of use.

[0036] In one embodiment, the docking groove 4 is a T-shaped structure. The structure of the docking groove 4 is designed to cooperate with the structure of the support plate 8. The two ends of the T-shaped structure can be smoothly connected with the I-shaped structure through the slot, thereby realizing the formation of the placement cavity 10, which is convenient for the subsequent placement and use of multiple groups of wiring harnesses to avoid interference with each other.

[0037] Working principle: In actual use, personnel can adjust the support column 9 and the support plate 8 accordingly according to the number and size of the wire harnesses that need to be passed through. When only one group of wire harnesses needs to be passed through, the support column 9 and the support plate 8 do not need to be installed, and the placement operation of the wire harness can be achieved only through the wire harness tube body 1. When multiple groups of wire harnesses need to be passed through, a corresponding number of support plates 8 can be inserted into the docking grooves 4 at different positions on the surface of the support column 9 according to the number and size of the wire harnesses. The space inside the wire harness tube body 1 can be effectively divided by the provision of the support plate 8, so that different wire harnesses can be placed in different placement cavities 10, avoiding interference and entanglement between the wire harnesses, thereby ensuring the effect of subsequent use, and after the support plate 8 is inserted, the wire harness tube can be supported by its own structure, and a metal ring 5 is provided inside the wire harness tube, which can also be It plays a role in enhancing strength. The combination of the two can effectively enhance the overall strength of use and support effect, improve the overall use effect, and then when the threading tube body 1 is damaged by the outside world, the metal ring 5 can provide a certain degree of blocking. If the blocking of the metal ring 5 cannot play an effective role, the external substances will destroy the sealing block 2. At this time, the color powder 3 inside the sealing block 2 will leak out, and then dye the surface of the threading tube. Subsequent personnel can quickly locate the damaged position through the dyed area. In addition, when the wiring harness is short-circuited or even broken, the influence of the current will cause the temperature of the corresponding position to be significantly different from the temperature of other surrounding areas. At this time, the color change of the color-changing temperature measuring patch 6 at the corresponding position can quickly locate the position where the wiring harness fails, which is convenient for subsequent timely processing. The device as a whole has the advantages of good abnormal positioning effect, adjustable threading space, and small wiring harness interference.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
