Description

Technical Field

[0001] This utility model relates to the field of cable installation, and in particular to a fixing structure for low-voltage cables. Background Technology

[0002] Low-voltage cables refer to cables used for security communications, electrical equipment, and related low-voltage transmission applications. They consist of an inner conductor, insulation, an outer conductor, and a sheath. The inner conductor significantly affects signal transmission; the insulation affects attenuation, impedance, and return loss; and the outer conductor acts as a return conductor and shield. The main differences between low-voltage and high-voltage cables lie in their AC frequency, transmission method, voltage level, and unique advantages. Cables are carriers of electrical energy and typically require constraint and fixation during installation.

[0003] In existing technologies, when constraining and fixing low-voltage cables, it is not possible to classify and fix multiple low-voltage cables separately, and the low-voltage cables are easily damaged by radial pressure during the fixing process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fixing structure for low-voltage cables. The technical solution of this utility model is as follows:

[0005] A low-voltage cable fixing structure includes a mounting bracket, a locking mechanism is installed on the upper end face of the mounting bracket, and positioning mechanisms are installed on both sides of the locking mechanism. The positioning mechanism includes a hollow mounting base, a plurality of elastic positioning seats are installed on the inner side of the hollow mounting base, and elastic guide tabs are installed at both ends of the elastic positioning seats.

[0006] The locking mechanism includes a transmission bar, and multiple arc-shaped locking hooks are installed on the upper end face of the transmission bar. The inner wall of the arc-shaped locking hooks is provided with multiple anti-slip teeth.

[0007] Preferably, the mounting bracket includes a support strip, a plurality of magnetic blocks are fixedly installed on the lower end face of the support strip, mounting holes are provided at the four corners of the support strip, a guide strip is installed on the upper end face of the support strip, and an adjustment knob is rotatably connected to the inner side of the bottom end of the guide strip.

[0008] Preferably, the support strip and the guide strip are fixedly connected by screws, one side of the elastic positioning seat is provided with a slot, both sides of the guide strip are inserted into the inner side of multiple slots, and the support strip and multiple elastic positioning seats are fixedly connected by the guide strip.

[0009] Preferably, the support strip is fixedly connected to the mounting hollow seat by screws, and the plurality of elastic positioning seats are arranged linearly along the axis of the mounting hollow seat. Both ends of the elastic positioning seats are connected to the mounting hollow seat by elastic guide tabs.

[0010] Preferably, the upper end face of the guide bar is provided with a groove, the transmission bar is disposed inside the groove and slidably connected to the guide bar, and the transmission bar is fixedly connected to multiple arc-shaped locking hooks.

[0011] Preferably, one end of the adjustment knob passes through the bottom end of the guide bar and is connected to the transmission bar by a thread, and each pair of adjacent elastic positioning seats are coaxial with the transmission bar.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] By pressing the low-voltage cables, they are inserted into the inner side of the elastic positioning seat through the action of two adjacent elastic guide tabs. Multiple elastic positioning seats can then simultaneously and initially position multiple low-voltage cables. When the adjustment knob is rotated, it drives the transmission bar to slide on the upper surface of the guide bar. The transmission bar then drives multiple arc-shaped locking hooks to push the low-voltage cables laterally, realizing the clamping and fixing operation of the low-voltage cables by the elastic positioning seats and the transmission bar. The anti-slip rack can effectively prevent axial slippage of the arc-shaped locking hooks during the clamping process, effectively maintaining the installation stability of multiple low-voltage cables. The mounting holes facilitate the support strip to be fixed to the equipment with screws, or it can be magnetically fixed by multiple magnetic blocks, facilitating the overall assembly and disassembly.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figures 1 to 3 As shown, the present invention discloses a low-voltage cable fixing structure, including a mounting bracket 1. A locking mechanism 3 is installed on the upper end face of the mounting bracket 1. The mounting bracket 1 includes a support strip 101. Multiple magnetic blocks 105 are fixedly installed on the lower end face of the support strip 101. Mounting holes 102 are provided at the four corners of the support strip 101. A guide strip 103 is installed on the upper end face of the support strip 101. The support strip 101 and the guide strip 103 are fixedly connected by screws. An adjustment knob 104 is rotatably connected to the inner side of the bottom end of the guide strip 103. The support strip 101 can be fixed to the equipment by screws through the mounting holes 102, or it can be magnetically fixed by multiple magnetic blocks 105, which facilitates the overall assembly and disassembly.

[0022] As a preferred technical solution in this embodiment, such as Figures 1 to 4 As shown, positioning mechanisms 2 are installed on both sides of the locking mechanism 3. The positioning mechanism 2 includes a hollow mounting base 201. Multiple elastic positioning seats 202 are installed on the inner side of the hollow mounting base 201. One side of the elastic positioning seat 202 is provided with a slot. Both sides of the guide pressure strip 103 are inserted into the inner side of the multiple slots. The support strip 101 and the multiple elastic positioning seats 202 are fixedly connected through the guide pressure strip 103. The guide pressure strip 103 facilitates the synchronous positioning and pressing of the multiple elastic positioning seats 202.

[0023] Both ends of the elastic positioning seat 202 are equipped with elastic guide tabs 203. The support strip 101 is fixedly connected to the mounting hollow seat 201 by screws. Multiple elastic positioning seats 202 are arranged linearly along the axis of the mounting hollow seat 201. Both ends of the elastic positioning seat 202 are connected to the mounting hollow seat 201 by elastic guide tabs 203. The low-voltage cable is inserted into the inner side of the middle of the elastic positioning seat 202 under the action of two adjacent elastic guide tabs 203. Multiple elastic positioning seats 202 can perform synchronous preliminary positioning of multiple low-voltage cables.

[0024] As a preferred technical solution in this embodiment, such as Figure 4 and Figure 5 As shown, the locking mechanism 3 includes a transmission bar 303. Multiple arc-shaped locking hooks 301 are mounted on the upper surface of the transmission bar 303. Multiple anti-slip racks 302 are provided on the inner wall of the arc-shaped locking hooks 301. A sliding groove is provided on the upper surface of the guide pressure strip 103. The transmission bar 303 is located inside the sliding groove and slidably connected to the guide pressure strip 103. The transmission bar 303 is fixedly connected to the multiple arc-shaped locking hooks 301. One end of the adjusting knob 104 passes through the bottom end of the guide pressure strip 103 and is threadedly connected to the transmission bar 303. Each pair of adjacent elastic positioning seats 202 are coaxial with the transmission bar 303. The elastic positioning seats 202 and the transmission bar 303 perform a pressing and fixing operation on the low-voltage cables. The anti-slip racks 302 effectively prevent axial sliding of the arc-shaped locking hooks 301 during the pressing process of the low-voltage cables, effectively maintaining the installation stability of multiple low-voltage cables.

[0025] Working principle: When constraining low-voltage cables, the support strip 101 is fixedly connected to two hollow mounting bases 201, so that multiple elastic positioning bases 202 are linearly arranged on the inner side of the hollow mounting bases 201. Then, the multiple elastic positioning bases 202 and the support strip 101 are pressed and fixed by the guide pressure strip 103, and both ends of the elastic positioning bases 202 are connected to the hollow mounting bases 201 by elastic guide tabs 203. The low-voltage cables are pressed, so that the low-voltage cables are inserted into the inner side of the middle of the elastic positioning bases 202 under the action of two adjacent elastic guide tabs 203. Thus, multiple elastic positioning bases 202 can synchronously and initially position multiple low-voltage cables.

[0026] Then, the adjustment knob 104 is rotated, causing the adjustment knob 104 to slide on the upper surface of the guide bar 103 under the support of the guide bar 103. In turn, the drive bar 303 drives multiple arc-shaped locking hooks 301 to push the low-voltage cable laterally, realizing the operation of pressing and fixing the low-voltage cable by the elastic positioning seat 202 and the drive bar 303. At the same time, multiple anti-slip teeth 302 are provided on the inner wall of the arc-shaped locking hook 301, which can effectively prevent axial sliding of the arc-shaped locking hook 301 during the pressing of the low-voltage cable, effectively maintaining the installation stability of multiple low-voltage cables. Mounting holes 102 are provided at the four corners of the support bar 101, which can be used to fix the support bar 101 to the equipment with screws or magnetically fixed by multiple magnetic blocks 105, which facilitates the overall assembly and disassembly.
