Description

Technical Field

[0001] This utility model relates to the field of cable fixing technology, specifically to a cable fixing device for electrical construction. Background Technology

[0002] In cable laying projects, cable trays (also known as cable boxes) serve as critical infrastructure for protecting and organizing cables. The reliable securing of cables within these trays is a fundamental requirement for ensuring system safety, stable operation, and compliance with electrical installation standards. Currently, the industry commonly uses nylon cable ties (cable ties) or metal / plastic clamps (saddle clamps) for cable fixing. These are achieved by passing them through pre-drilled holes at the bottom of the cable tray or by utilizing the tray's structure for binding and locking, thus positioning and constraining the cable bundles.

[0003] Nylon cable ties, as disposable fasteners, can only be cut when they need to be removed for inspection or replacement of cables. The narrow and congested space inside the cable tray makes it difficult to quickly cut the cable ties, and may also damage the cable insulation. For clamps (which usually need to be fixed to the bottom of the cable tray with screws), each clamp can only be installed in one hole at the bottom of the cable tray. This means that the cables in the cable tray can only be fixed by passing through a single cable or multiple cables stacked together. Fixing only a single cable will waste the space inside the cable tray. If multiple cables are placed in the clamp at the same time, it is not convenient to classify the cables. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a cable fixing device for electrical construction.

[0005] The technical solution of this utility model is as follows:

[0006] A cable fixing device for electrical construction includes an elongated trough and a trough cover thereon. The bottom surface of the elongated trough has a plurality of elongated holes along its length. The elongated trough is provided with a plurality of mounting bases. The mounting bases are detachably connected to the holes and are adapted to the holes. The upper end surface of the mounting base is provided with a support plate located above the bottom surface, and the upper end surface is provided with a cable clamping unit.

[0007] The cable clamping unit includes a clamping base with multiple clamping slots arranged along the width of the elongated groove. The clamping base is provided with an openable cover plate. The lower end face of the cover plate is provided with multiple pressing members corresponding to the clamping slots. The pressing members are detachably connected to the cover plate, and the position of the pressing members is adjustable along the direction perpendicular to the bottom surface of the elongated groove.

[0008] The specific structure of the pressing component is as follows: the pressing component includes a sleeve connected to the cover plate through an adjusting component. One end of the adjusting component is rotatably connected to the sleeve, and the adjusting component is threadedly connected to the cover plate. The axis of the sleeve is perpendicular to the cover plate. An opening is provided on the side of the sleeve away from the cover plate. A pressing plate is provided on the outside of the opening. The pressing plate is connected to the inner wall of the sleeve through an elastic component.

[0009] The structure of the above-mentioned elastic element is as follows: the elastic element is a compression spring, and the maximum length that the elastic element can reach is 1-3 cm greater than the maximum length of the sleeve. When the cable located in the elongated cable groove is placed in the corresponding clamping groove, by closing the cover plate, the elastic element presses down on the lower pressure plate to achieve the function of clamping the cable in the clamping groove and preventing the cable from moving.

[0010] Furthermore, the lower pressure plate is an arc-shaped plate with the arc direction facing the bottom surface of the clamping groove. The lower pressure plate and the clamping groove can form a clamping opening for clamping the cable.

[0011] To reduce the tendency of the compression spring to shift to one side when compressed, a telescopic rod is provided inside the sleeve. One end of the telescopic rod is connected to the side of the sleeve near the cover plate, and the other end is hinged to the lower pressure plate. The compression spring is sleeved on the outside of the telescopic rod.

[0012] Furthermore, the shortest length that the telescopic rod can reach is less than the length of the sleeve.

[0013] The specific structure of the telescopic rod is as follows: the telescopic rod includes a first adjusting tube and a second adjusting tube that are sleeved together. The second adjusting tube is sleeved inside the first adjusting tube. The ends of the first adjusting tube and the second adjusting tube are provided with corresponding limiting platforms to prevent the second adjusting tube from detaching from the first adjusting tube. The first adjusting tube is closer to the cover plate, and the length of the first adjusting tube is less than the length of the sleeve.

[0014] Furthermore, the adjusting component is an adjusting bolt, the axis of which is perpendicular to the cover plate.

[0015] The mounting base and the elongated cable tray are detachably connected in the following structure: the mounting base has an extension threaded rod extending outward from the hole on the side away from the clamping seat, and a nut is threaded onto the extension threaded rod. The outer diameter of the nut is larger than the width of the hole.

[0016] The specific structure of the cover plate on the clamping seat is that one end of the cover plate is hinged to one side of the upper part of the clamping seat, and the other end is snapped to the other side of the upper part of the clamping seat.

[0017] The beneficial effects of this utility model are as follows:

[0018] Utilizing the existing hole design of the elongated cable tray, the mounting base is fixed to the elongated cable tray by an extension threaded rod and nut passing through the hole, which enables quick assembly and disassembly with the elongated cable tray without damaging it.

[0019] The clamping slots on the mounting base can hold cables. There are multiple clamping slots, which can classify and place cables of different models. After all the cables are placed, as the cover is slowly closed, the lower pressure plate will abut against the outer surface of the cable. As the cover is continued to be clamped onto the clamping base, the compression spring will be compressed, gradually pressing the lower pressure plate against the outer surface of the cable to achieve cable clamping.

[0020] The pressure plate and the sleeve have a certain distance. This distance can not only clamp cables of different sizes, but also avoid damage to the cable surface caused by excessive pressure from the pressure plate.

[0021] To further avoid insufficient space for adjustment of the lower pressure plate due to excessively large cable diameter, and to avoid the lower pressure plate failing to clamp the cable due to excessively small cable diameter, a sleeve is provided that is connected to the cover plate through an adjusting component. This allows for adjustment of the position of the sleeve, compression spring, and lower pressure plate, making it suitable for clamping cables of different diameters.

[0022] The cable clamping unit can be quickly installed and removed from the elongated slot, which facilitates the quick installation and fixation of cables and allows for reuse. Attached Figure Description

Detailed Implementation

[0033] See Figure 1 , Figure 2 and Figure 5 As shown, a cable fixing device for electrical construction includes an elongated trough 1 and a trough cover 9 covering it. The bottom surface of the elongated trough 1 has a plurality of elongated holes 101 along its length. The elongated trough 1 has a plurality of mounting bases 2. The mounting bases 2 are detachably connected to the holes 101. The mounting bases 2 are adapted to the holes 101, and the thickness of the mounting bases 2 is shorter than the depth of the holes 101. The upper end surface of the mounting bases 2 is provided with a support plate 201 located above the bottom surface. The mounting bases 2 are provided on the upper end surface.

[0034] The mounting base 2 is detachably connected to the elongated groove in that the mounting base 2 has an extension threaded rod 202 extending outward from the hole 101 on the side away from the clamping seat 3. A nut 8 is threaded onto the extension threaded rod 202. The outer diameter of the nut 8 is larger than the width of the hole 101. Tightening the nut 8 can tighten the mounting base 2 onto the hole 101, preventing the mounting base 2 and the mounting base 2 on it from detaching from the elongated groove 1.

[0035] The cable clamping unit includes a clamping base 3, which has multiple clamping slots 301 arranged along the width direction of the elongated groove 1. The clamping base 3 has an openable cover plate 4, one end of which is hinged to one side of the upper part of the clamping base 3, and the other end of which is engaged with the other side of the upper part of the clamping base 3. The plane of the rotation trajectory of the cover plate 4 is parallel to the width direction of the elongated groove 1. The lower end face of the cover plate 4 has multiple pressing members 5 corresponding to the clamping slots 301. The pressing members 5 are detachably connected to the cover plate 4, and their position is adjustable along the direction perpendicular to the bottom surface of the elongated groove 1. In this embodiment, the clamping base 3 has three clamping slots 301; therefore, three sets of pressing members 5 are provided.

[0036] The clamping slots 301 of the clamping seat 3 on the mounting base 2 can hold cables. There are multiple clamping slots 301, which can classify and place cables of different models. After all the cables are placed, while the cover plate 4 is slowly closed, the lower pressure plate 503 will abut against the outer surface of the cable. As the cover plate 4 continues to be clamped onto the clamping seat 3, the compression spring will be compressed, and the lower pressure plate 503 will be gradually pressed against the outer surface of the cable to achieve the clamping of the cable.

[0037] See Figure 2 , Figure 3 and Figure 4 As shown, to further avoid insufficient space for adjustment of the lower pressure plate 503 due to excessively large cable diameter, and to avoid the lower pressure plate 503 failing to compress the cable due to excessively small cable diameter, a sleeve 502 is connected to the cover plate 4 via an adjusting member 501. This allows for adjustment of the positions of the sleeve 502, compression spring, and lower pressure plate 503, making it suitable for compressing cables of different diameters. Specifically, a single lower pressure member 5 includes a sleeve 502 connected to the cover plate 4 via an adjusting member 501. One end of the adjusting member 501 is rotatably connected to the sleeve 502, and the adjusting member 501 is threadedly connected to the cover plate 4. The axis of the sleeve 502 is perpendicular to the cover plate 4. The side of the sleeve 502 away from the cover plate 4 has an opening, and a lower pressure plate 503 is located outside the opening. The lower pressure plate 503 is connected to the inner wall of the sleeve 502 via an elastic member 504.

[0038] The elastic element 504 is a compression spring. The maximum length achievable by the elastic element 504 is 1-3 cm longer than the maximum length of the sleeve 502. When the cable located in the elongated cable groove is placed in the corresponding clamping groove 301, closing the cover plate 4 causes the elastic element 504 to press down on the lower pressure plate 503, clamping the cable within the clamping groove 301 and preventing cable movement. The adjusting element 501 is an adjusting bolt, with its axis perpendicular to the cover plate 4. The threaded section of the adjusting element 501, away from the sleeve 502, passes through the cover plate 4. A nut is located at the end of the adjusting element 501 away from the sleeve 502, on the outside of the cover plate 4, allowing for easy tightening or loosening for adjustment.

[0039] See Figure 6 As shown, the lower pressure plate 503 is an arc-shaped plate with the arc direction facing the bottom surface of the clamping groove 301. The lower pressure plate 503 and the clamping groove 301 can form a clamping opening for clamping the cable. The arc-shaped plate can increase the contact area with the outer surface of the cable and reduce pressure damage to the outer surface of the cable.

[0040] See Figure 7As shown, to reduce the tendency of the compression spring to shift to one side during compression, a telescopic rod 6 is provided inside the sleeve 502. One end of the telescopic rod 6 is connected to the side of the sleeve 502 near the cover plate 4, and the other end is hinged to the lower pressure plate 503. The compression spring is sleeved on the outside of the telescopic rod 6. To increase the stroke of the lower pressure rod and make it suitable for clamping cables of different outer diameters, the shortest length that the telescopic rod 6 can reach is less than the length of the sleeve 502. The telescopic rod 6 includes a first adjusting tube 601 and a second adjusting tube 602 that are sleeved together. The second adjusting tube 602 is sleeved inside the first adjusting tube 601. The ends of the first adjusting tube 601 and the second adjusting tube 602 are provided with corresponding limiting platforms 7 to prevent the second adjusting tube 602 from detaching from the first adjusting tube 601. The first adjusting tube 601 is located near the cover plate 4, and the length of the first adjusting tube 601 is less than the length of the sleeve 502. One end of the first adjusting tube 601 is connected to the end of the sleeve 502 near the adjusting member 501, and the end of the second adjusting tube 602 away from the adjusting member 501 is hinged to the lower pressure plate 503, so that the lower pressure plate 503 can adjust the angle according to its own position and the position of the cable, so as to smoothly press the cable down.
