Description

Technical Field

[0001] This utility model relates to the technical field of pipeline heat tracing accessories, specifically a high-temperature resistant heat tracing cable integrated with cable ties. Background Technology

[0002] In industrial and civilian applications, heating cables are commonly used for heating and insulation of equipment such as gas pipes, storage tanks, and heat pumps that require temperature maintenance. However, current common installation methods for heating cables have several drawbacks: First, traditional heating cables and fixing components are independent, requiring separate installation operations. The cable is first laid on the equipment surface, then secured with cable ties, tape, and other auxiliary tools, a cumbersome process with low installation efficiency. Second, commonly used cable ties are often made of ordinary materials, which are prone to aging and embrittlement at high temperatures, leading to poor fixing effects, loosening and displacement of the heating cable, and affecting the heating performance. Third, ordinary cable ties are mostly for single use, resulting in resource waste and increased operating costs. Utility Model Content

[0003] The purpose of this invention is to provide an integrated high-temperature resistant cable tracing tape, which effectively solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution.

[0005] A high-temperature tracing cable integrated with a cable tie includes a cable tie and a tracing cable. The cable tie has a groove extending along its length, and the cross-sectional shape of the groove matches the shape of the tracing cable. The tracing cable is correspondingly fitted into the groove, with its end located in the groove and adjacent to one end of the cable tie. A fastening mechanism is fixedly connected to the end of the cable tie adjacent to the end of the tracing cable. A fastening strip is provided at the other end of the cable tie, and several protruding teeth are evenly distributed on the fastening strip. The fastening mechanism engages with the protruding teeth on the fastening strip to achieve locking.

[0006] Furthermore, the slot opening size is smaller than the diameter of the heat tracing cable.

[0007] Furthermore, the binding strap has several adhesive strips evenly distributed on the surface where the slot opening is located, and each adhesive strip extends along the length of the binding strap; when tightened, the adhesive strips and the heat tracing cable also adhere to the surface of the object to be heated.

[0008] Furthermore, a lead-out notch is provided on the heat tracing cable near the fastening mechanism. The lead-out notch is connected to the slot so that the heat tracing cable can be bent and led out.

[0009] Furthermore, the fastening mechanism includes a fastening head, a locking tooth, and an adjusting device; the fastening head is fixed to the end of the restraint strap, and the fastening head has a through-hole for the fastening strip to pass through; a side groove is provided on the inner wall of the through-hole; the locking tooth is slidably installed in the side groove and meshes with the protruding tooth; the adjusting device is located on the side of the fastening head and is used to adjust the extension and retraction of the locking tooth.

[0010] Furthermore, the adjusting device includes a threaded rod; the side of the fastening head is provided with a threaded hole that communicates with the side groove, and the threaded rod is threadedly installed in the threaded hole; one end of the threaded rod extends into the side groove and is rotatably connected with the retaining teeth, and the other end extends to the outside of the fastening head and is fixed with a handle.

[0011] Furthermore, several restraint sleeves are evenly distributed on the restraint strap near the fastening head.

[0012] Furthermore, both the restraint straps and the adhesive strips are made of polyetheretherketone or polyphenylene sulfide.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] The heat tracing cable is integrated into a single structure by being embedded in a slot on the binding strap or directly connected to the fastening strip and fastening mechanism. The fastening mechanism engages with the protruding teeth on the fastening strip to achieve positioning and locking. No disassembly is required, and the entire process can be completed in one binding. This streamlined process significantly improves the efficiency of large-scale or emergency heat tracing installation in industry.

[0015] The threaded rod engages with the threaded hole, and rotating the handle drives the locking teeth to extend and retract, allowing the locking teeth to repeatedly engage and disengage with the protruding teeth, supporting multiple cycles and reducing material consumption.

[0016] The slot opening size is smaller than the diameter of the heat tracing wire, forming an interference fit to prevent the heat tracing wire from coming out. The bonding strip and the heat tracing wire are bonded together to the body to be heated, improving the heat adhesion and heat conduction efficiency. The bonding strip can also limit the displacement of the heat tracing wire, ensuring the uniformity of the heat tracing temperature.

[0017] The binding straps and bonding strips are made of polyetheretherketone or polyphenylene sulfide, which can maintain excellent mechanical strength and anti-aging properties at high temperatures. The two together form a cover to enclose the heat tracing cable, isolate it from impurities and ensure the stability and heat tracing effect of the heat tracing cable under high temperature conditions.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0022] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0023] This utility model provides an integrated high-temperature resistant cable tracing tape, comprising a cable tie 1 and a cable tracing wire 2. The cable tracing wire 2 has a heating core wire inside, and the heating core wire is wrapped with an insulation layer, a shielding layer and an outer sheath in sequence. It can stably generate heat, provide heat to the equipment and maintain temperature stability. The insulation layer ensures electrical safety, the shielding layer can prevent electromagnetic interference, and the outer sheath provides mechanical protection and moisture protection. Example 1

[0024] Please see Figures 1-8 The binding strap 1 has a slot 11 extending along its length, and the cross-sectional shape of the slot 11 matches the shape of the heat tracing wire 2. The slot 11 has an opening for the heat tracing wire 2 to be inserted, and the opening size is smaller than the diameter of the heat tracing wire 2. Since the heat tracing wire 2 is made of multiple flexible materials, it is elastic. When the heat tracing wire 2 is inserted into the slot 11 from the opening, the heat tracing wire 2 deforms until it is fully inserted into the slot 11. Then, the heat tracing wire 2 will reset and fit into the slot 11, thereby integrating the heat tracing wire 2 and the cable tie structure provided in this application.

[0025] It is worth noting that the process of embedding the heat tracing cable 2 into the slot 11 is carried out after the heat tracing cable 2 is produced and before it is fastened to the object to be heated. The heat tracing cable 2 and the binding strap 1 are connected as a whole, and the installation can be completed with only one binding action, which simplifies the installation process, improves the installation efficiency, and is suitable for emergency heating and large-scale installation scenarios.

[0026] Furthermore, when the heat tracing cable 2 is fitted into the slot 11, the end of the heat tracing cable 2 is simultaneously located in the slot 11 and close to one side end of the binding strap 1. It can be understood that the cable tie structure provided in this application is mainly set at the end of the heat tracing cable 2.

[0027] The binding strap 1 is fixedly connected to the end of the heat tracing cable 2 with a fastening mechanism 4. The other end of the binding strap 1 is provided with a fastening strip 3, which has several protruding teeth 31 evenly distributed on it. The binding strap 1 with the heat tracing cable 2 embedded in it is wrapped around the surface of the object to be heated. Then, the fastening mechanism 4 engages with the protruding teeth 31 on the fastening strip 3 to achieve overall locking, thus firmly binding the heat tracing cable 2 to the object to be heated.

[0028] like Figure 8As shown, the heat tracing cable 2 has an outlet notch 13 near the fastening mechanism 4. The outlet notch 13 is connected to the slot 11. The heat tracing cable 2 bends in an L-shape near the outlet notch 13 and is led out from the outlet notch 13 to the outside of the binding strap 1, so as to facilitate the connection of the heat tracing cable 2 to the power cord. Example 2

[0029] This embodiment is another variation of Embodiment 1, the difference being: The fastening mechanism 4 is fixed to the end of the heat tracing wire 2, and the fastening strip 3 is fixed to the heat tracing wire 2. During the specific installation, the heat tracing wire 2 is wrapped around the surface of the object to be heated. Then, the fastening mechanism 4 and the protruding teeth 31 on the fastening strip 3 are engaged to firmly bind the heat tracing wire 2 to the object to be heated. In this embodiment, the fastening and binding are achieved by the heat tracing wire 2 itself wrapping around the surface of the object to be heated. Example 3

[0030] Please see Figure 3 Based on Example 1, this example is further optimized as follows: The binding strap 1 has several evenly distributed adhesive strips 12 on the surface where the slot 11 opening is located. Each adhesive strip 12 extends along the length of the binding strap 1. When the binding strap 1 and the heating cable 2 are wrapped around the surface of the object to be heated and tightened, the adhesive strips 12 and the heating cable 2 also adhere to the surface of the object to be heated. Furthermore, as... Figure 3 and Figure 4 As shown, the tracing line 2 is distributed between two adjacent bonding strips 12.

[0031] This design ensures that the heat tracing cable 2 can be tightly attached to the surface of the object to be heated, ensuring good heating effect. At the same time, the binding strap 1 and the bonding strip 12 form a cover structure, which cooperates with the surface of the object to be heated to cover the heat tracing cable 2 inside, further achieving the effects of heat preservation and protection.

[0032] In addition, the heat tracing line 2 is located between two adjacent bonding strips 12. Even if the heat tracing line 2 is pulled out of the slot 11 by external force, it will be limited between the two bonding strips 12 by the obstruction of the bonding strips 12, so as to avoid displacement and ensure the accuracy of the heating position.

[0033] The binding strap 1 and the bonding strip 12 are both made of polyetheretherketone or polyphenylene sulfide. The binding strap 1 and the bonding strip 12 that are in contact with or close to the heat tracing cable 2 are made of high temperature resistant materials, which can adapt to high temperature environments and are not easy to age or be damaged after long-term use, with a long service life, ensuring that the heat tracing effect is not affected under high temperature conditions. Example 4

[0034] Please see Figure 5 and Figure 6This embodiment is used to further explain the fastening mechanism 4 in Embodiments 1 and 2, as follows: The fastening mechanism 4 includes a fastening head 41, a locking tooth 42, and an adjusting device 43. The fastening head 41 is fixed to the end of the restraint strap 1. The fastening head 41 has a through hole 411 for the fastening strip 3 to pass through. The inner wall of the through hole 411 has a side groove 412. The locking tooth 42 is slidably installed in the side groove 412 and meshes with the protruding tooth 31. The adjusting device 43 is located on the side of the fastening head 41 and is used to adjust the extension and retraction of the locking tooth 42.

[0035] The adjusting device 43 includes a threaded rod 432. The fastening head 41 has a threaded hole 431 that communicates with the side groove 412. The threaded rod 432 is threadedly installed in the threaded hole 431. One end of the threaded rod 432 extends into the side groove 412 and is rotatably connected to the retaining tooth 42. The other end extends to the outside of the fastening head 41 and is fixed with a handle 433.

[0036] The specific fastening principle between fastening mechanism 4 and fastening strip 3 is as follows: Step 1: By squeezing the handle 433 and applying force to turn the threaded rod 432, the threaded hole 431 and the threaded rod 432 are engaged, causing the retaining tooth 42 to slide back into the side groove 412, thereby freeing up the internal space of the through hole 411. Step 2: Wrap the binding strap 1 and the heat tracing line 2 around the object to be heated, then pass the fastening strip 3 through the through hole 411, and adjust the length of the fastening strip 3 until the heat tracing line 2 is attached to the surface of the object to be heated. Step 3: Pinch the handle 433 and twist the threaded rod 432 in the opposite direction to push the side groove 412 to slide in the opposite direction until the side groove 412 extends into the through hole 411 and engages with the two protruding teeth 31 at the corresponding position on the fastening strip 3. At this time, the fastening strip 3 is locked and limited to achieve overall binding, and the installation of the heat tracing line 2 is completed.

[0037] Furthermore, in the state of step three, when it is necessary to untie, simply repeat the action of step one. By turning the threaded rod 432, the locking tooth 42 is driven to slide back into the side groove 412, canceling the engagement state between the locking tooth 42 and the protruding tooth 31, so that the fastening strip 3 can be restored to a state of free movement and adjustment. This allows the cable tie to support multiple opening and closing, realize the reuse of the device, and reduce material waste.

[0038] In addition, different specifications of heat tracing cable 2 and matching length of binding strap 1 can be selected according to the needs of different equipment, so that it can be widely used in various equipment such as gas pipes, storage tanks, and heat pumps that require heat tracing and insulation, and has high versatility. Example 5

[0039] Because the length of the fastening strip 3 after passing through the through hole 411 is relatively long, such as Figure 1 and Figure 2 As shown, this application has several binding sleeves 101 evenly distributed on the binding strap 1 near the fastening head 41. By passing the protruding part of the fastening strip 3 through each binding sleeve 101 in sequence, the protruding fastening strip 3 can be neatly and orderly stored by the binding sleeve 101.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
