Description

Technical Field

[0001] This utility model relates to the field of cable fixing bracket technology, specifically a cable fixing bracket for power transmission and transformation projects. Background Technology

[0002] The transmission of electric current often results in losses due to heat generation in the lines. Therefore, during transmission, voltage is increased through substations to reduce the current and minimize heat loss. High-voltage electricity is highly dangerous, and the target electrical appliances do not require such high voltage, necessitating voltage reduction through substations. Because multiple substations are required during current transmission, the process is called power transmission and transformation. In power transmission and transformation projects, fixed supports are used to secure the cables.

[0003] Chinese utility model CN213636894U describes a cable fixing bracket for power transmission and transformation projects. The bracket is designed to clamp and fix cables of various specifications. The principle is that by rotating the handle, the threaded rod is rotated, so that the fixing ring comes close to clamp the cable. Then, by rotating the bolt, the compression ring comes into contact with the top of the cable, and the cable is clamped and fixed by squeezing the cable in three directions.

[0004] However, existing devices require operation on both bolts and threaded rods to secure the cable, making the process cumbersome. Furthermore, the cable is only compressed from three directions, resulting in poor fixation. Therefore, to address these issues, a new device was designed that is simple to operate and can compress the cable from multiple directions, improving its stability. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a cable fixing bracket for power transmission and transformation projects, which has the following beneficial effects:

[0018] 1. This cable fixing bracket uses the rotation of the threaded rod through the extrusion assembly to drive the slide plate to move inside the support frame, thereby causing the upright plate to slide inside the groove, and dragging the top ring body to move outside the tube body. During the movement, it will contact the extrusion block and push the extrusion block into the tube body so that the bottom end of the extrusion block contacts the outer wall of the cable, and extrudes and fixes the cable.

[0019] 2. After the cable is clamped and fixed by the fixing component, the knob needs to be restricted to prevent it from rotating in order to ensure the fixation is firm. At this time, it is only necessary to insert the plug through the knob and into the positioning hole to restrict the rotation of the knob. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] The transmission of electric current often results in losses due to heat generation in the lines. Therefore, during transmission, voltage is increased through substations to reduce the current and minimize heat loss. High-voltage electricity is highly dangerous, and the target electrical appliances do not require such high voltage, necessitating voltage reduction through substations. Because multiple substations are required during current transmission, the process is called power transmission and transformation. In power transmission and transformation projects, fixed supports are used to secure the cables.

[0032] In related technologies, rotating the handle drives the threaded rod to rotate, bringing the fixing ring closer to clamp the cable. Then, rotating the bolt causes the compression ring to contact the top of the cable, compressing the cable from three directions to clamp and fix it. However, existing devices require operation of both the bolt and the threaded rod to fix the cable, which is cumbersome, and the three-directional compression alone results in poor fixing effectiveness.

[0033] To address some of the problems in related technologies, this application provides a cable fixing bracket for power transmission and transformation projects. When cable fixing is required, the support frame 11 is first fixed inside the cable trench, and then the cable passes through the inside of the pipe body 12. To fix the cable, simply rotate the threaded rod 22. As the threaded rod 22 rotates, it causes the sliding plate 21 to slide inside the support frame 11, simultaneously moving the upright plate 24 inside the sliding groove 23. During the movement of the upright plate 24, its top end causes the ring 25 to move on the outer wall of the pipe body 12. During this movement, the ring 25 contacts the compression block 26, causing the compression block 26 to insert into the inside of the pipe body 12 and contact the surface of the cable, thus clamping and fixing the cable in multiple directions. After fixing the cable, the threaded rod 22 needs to be restricted to ensure the fixation is secure. Simply grasp the circular plate 33 and insert the insertion rod 32 through the knob 221 into the positioning hole 31 to restrict the knob 221, thereby preventing the threaded rod 22 from rotating and ensuring the stability of the fixation.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4 This application provides a cable fixing bracket for power transmission and transformation projects, including: a support frame 11 with multiple tubes 12 on its top; a pressing assembly 2 on the support frame 11, the pressing assembly 2 including: a sliding plate 21 slidably disposed inside the support frame 11, with its upper and lower ends abutting against the inner sidewall of the support frame 11; a threaded rod 22 with one end inserted into the interior of the support frame 11, passing through the sliding plate 21 and rotatably connected to the support frame 11, and threadedly connected to the sliding plate 21; a groove 23 formed at the top of the support frame 11; a vertical plate 24 with its bottom end inserted into the groove 23 and connected to the sliding plate 21; a ring 25 sleeved on the outside of the tubes 12, with both sides fixedly connected to the top of the vertical plate 24; and a pressing block 26 disposed inside the tubes 12, with its top end penetrating the inner sidewall of the tubes 12.

[0036] Specifically, a through groove is provided at the connection between the extrusion block 26 and the tube body 12, through which the extrusion block 26 is inserted into the interior of the tube body 12. The upright plate 24 is fixedly connected to the slide plate 21 and the ring body 25.

[0037] When it is necessary to fix the cable during use, first fix the support frame 11 inside the cable trench, then pass the cable through the inside of the pipe body 12. Then, to fix the cable, simply rotate the threaded rod 22. When the threaded rod 22 rotates, it drives the slide plate 21 to slide inside the support frame 11, and at the same time drives the upright plate 24 to move inside the slide groove 23. During the movement of the upright plate 24, the top will drive the ring body 25 to move on the outer wall of the pipe body 12. During the movement, it will come into contact with the squeezing block 26. Thus, the squeezing block 26 is inserted into the inside of the pipe body 12 by the push of the ring body 25 and comes into contact with the surface of the cable, thereby clamping and fixing the cable in multiple directions.

[0038] In some embodiments, the extrusion assembly 2 further includes: a crossbar 211 with one symmetrical end passing through the slide plate 21, and both ends connected to the inner sidewall of the support frame 11.

[0039] When in use, the crossbar 211 can stabilize the movement trajectory of the slide plate 21, allowing the slide plate 21 to move stably inside the support frame 11.

[0040] In some embodiments, a knob 221 is disposed at one end of the threaded rod 22.

[0041] It is easy to grip when using, and the grooves on the surface of the knob 221 can increase friction when gripping and rotating, making it less likely to slip and easier to rotate.

[0042] In some embodiments, the extrusion assembly 2 further includes an arc-shaped strip 261 fixedly disposed on the inclined surface of the extrusion block 26.

[0043] The curved strip 261 is designed to reduce the sharp edges when in contact with the ring 25, thereby reducing friction when in contact with the ring 25.

[0044] In some embodiments, the extrusion assembly 2 further includes an arc-shaped plate 27 disposed inside the tube 12 and connected to the bottom end of the extrusion block 26.

[0045] The curved plate 27 allows for better contact with the cable surface during use, thereby increasing the contact area and friction for a more secure fixation.

[0046] In some embodiments, the extrusion assembly 2 further includes: a groove 28 symmetrically formed on the inner sidewall of the tube 12; a spring 29 disposed inside the groove 28, with one end connected to the inner sidewall of the groove 28 and the other end connected to the arc plate 27.

[0047] Specifically, the two ends of the spring 29 are fixedly connected to the inner sidewalls of the arc plate 27 and the groove 28 by means of retaining rings.

[0048] During use, the rebound force of spring 29 can pull the arc plate 27 closer to the inner wall of tube 12, thereby reducing the obstruction to the cable when it passes through tube 12. At the same time, it can stabilize the position of the pressing block 26 and prevent it from detaching from tube 12.

[0049] In some embodiments, a fixing component 3 is provided on the knob 221. The fixing component 3 includes: multiple positioning holes 31, all of which are opened on the outer side wall of the support frame 11; multiple insertion rods 32, each of which has one end penetrating through the knob 221 and inserted into the interior of the positioning hole 31; and a circular plate 33 is provided at one end of the insertion rod 32.

[0050] After the cable is fixed, the threaded rod 22 needs to be restricted to ensure the fixation is firm. Simply grasp the round plate 33 and insert the rod 32 through the knob 221 into the positioning hole 31 to restrict the knob 221, thereby preventing the threaded rod 22 from rotating and ensuring the stability of the fixation.

[0051] In some embodiments, the fixing component 3 further includes a cone 34 disposed at one end of the insertion rod 32.

[0052] When in use, the pointed end of the cone 34 makes it easier to insert into the positioning hole 31. After one end of the cone 34 is inserted into the positioning hole 31, simply push the insert rod 32 to insert it into the positioning hole 31.
