Description

Technical Field

[0001] This utility model relates to the field of cable fixing and anti-slip technology in prefabricated cable trenches, and in particular to a cable fixing and anti-slip device for prefabricated cable trenches in cold regions. Background Technology

[0002] In cold regions, prefabricated cable trenches use anti-slip devices to secure cables within the trench, ensuring stability even in extreme weather conditions and preventing power outages or safety incidents caused by slippage or detachment.

[0003] According to the Chinese patent "A Prefabricated Cable Trench on the Ground" authorized announcement number "CN221467328U", a flat bottom plate is installed on the flat end bracket surface by means of a threaded rod. The bottom of the plate is pressed down stably on the cable at the end of the bracket by means of a nut and a threaded rod, thereby fixing the cable in the cable trench.

[0004] In the aforementioned application, the contact area between the cable and the card plate or bracket is small, making it difficult to stably fix the cable to prevent slippage, which in turn affects the safe use of the cable.

[0005] Therefore, a prefabricated cable trench cable fixing and anti-slip device for cold regions is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a cable fixing and anti-slip device for prefabricated cable trenches in cold regions to solve the above-mentioned problems, thereby improving the difficulty in stably fixing and preventing slippage of cables.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a cable fixing and anti-slip device for prefabricated cable trenches in cold regions, comprising: a mounting frame; a fixing mechanism, the fixing mechanism including a placement seat slidably connected to the inner wall of the mounting frame, a wire pressing seat provided on the top of the placement seat, a sliding frame fixedly connected to the inner walls of both the placement seat and the wire pressing seat, a rubber block slidably connected to the inner wall of the sliding frame, a mounting assembly provided on the surface of the placement seat, a spring and an elastic rod fixedly connected to the end of the rubber block, and the other ends of the spring and the elastic rod fixedly connected to the inner wall of the sliding frame. By using the placement seat, wire pressing seat, sliding frame, and rubber block, the area for clamping the cable is increased, thereby ensuring stable clamping of the cable and ensuring safe use of the cable. The elastic rod and spring ensure that the rubber block always contacts the cable surface, thereby improving the anti-slip performance of the cable inside the placement seat and the wire pressing seat.

[0008] Preferably, the mounting assembly includes a screw fixedly connected to the end of the cable clamp, and a nut is threaded onto the surface of the screw. The screw and nut secure the cable clamp to the mounting base, thereby achieving stable clamping of the cable.

[0009] Preferably, a stop is slidably connected to the lower end of the inner wall of the placement seat, and the end of the stop contacts the end of the nut.

[0010] Preferably, a spring is fixedly connected to one side of the abutment, and the other side of the spring is fixedly connected to the inner wall of the placement seat. The spring and the abutment together constrain the nut, ensuring that the nut is stably threaded onto the screw, thereby ensuring that the wire clamp is stably installed on the placement seat, thus improving the stability of the cable installation in the cable trench.

[0011] Preferably, a first pull rope is fixedly connected to one side of the support frame, and the other end of the first pull rope passes through the placement seat and is fixedly connected to a pull block.

[0012] Preferably, a second pull rope is fixedly connected to one side of one of the rubber blocks, and the other end of the second pull rope passes through one of the sliding frames and the pressure seat and is fixedly connected to a connecting block.

[0013] Preferably, a reinforcing frame is fixedly connected to the bottom of the placement base, and the surface of the reinforcing frame is slidably connected to the inner wall of the mounting frame. The reinforcing frame increases the support strength of the placement base, thereby ensuring effective support for the cable.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using a placement seat, a wire clamping seat, a sliding frame, and a rubber block, the area for clamping the cable is increased, thereby ensuring stable clamping of the cable. The elastic rod and spring ensure that the rubber block always contacts the cable surface, thus improving the anti-slip performance of the cable inside the placement seat and the wire clamping seat. Compared with existing methods that have a smaller cable clamping area, this method increases the clamping area of ​​the cable, thereby stably clamping the cable and ensuring safe use of the cable.

[0016] 2. The screw and nut secure the wire clamp to the mounting base, thus achieving stable clamping of the cable. The spring and the retainer limit the nut, ensuring that the nut is stably threaded onto the screw, thereby ensuring that the wire clamp is stably installed on the mounting base, which improves the stability of the cable installation in the cable trench.

[0022] 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.

[0023] In practical implementation: such as Figure 1-4 As shown, a cable fixing and anti-slip device for prefabricated cable trenches in cold regions includes: a mounting frame 2; and a fixing mechanism 3. The fixing mechanism 3 includes a placement seat 31 slidably connected to the inner wall of the mounting frame 2. A wire pressing seat 32 is provided on the top of the placement seat 31. A sliding frame 34 is fixedly connected to the inner walls of both the placement seat 31 and the wire pressing seat 32. A rubber block 36 is slidably connected to the inner wall of the sliding frame 34. A mounting assembly 38 is provided on the surface of the placement seat 31. A spring 35 and an elastic rod 37 are fixedly connected to the end of the rubber block 36. The other ends of the spring 35 and the elastic rod 37 are fixedly connected to the inner wall of the sliding frame 34. The elastic rod 37 is a nickel-titanium alloy component.

[0024] Multiple mounting frames 2 are installed sequentially in the cable trench using bolts. The cable is then laid in the placement seat 31, and the inner wall of the wire clamp 32 is pressed against the cable. Since the inner walls of both the placement seat 31 and the wire clamp 32 are concave and "V" shaped, the contact area between the placement seat 31, the wire clamp 32 and the cable is increased. At this time, the elastic force of the spring 35 and the elastic rod 37 pushes the rubber block 36 to move towards the cable, so that the rubber block 36 presses against the cable surface.

[0025] like Figure 3-4As shown, the mounting assembly 38 includes a screw 382 fixedly connected to the end of the wire clamping seat 32, a nut 381 threadedly connected to the surface of the screw 382, ​​a retainer 383 slidably connected to the lower end of the inner wall of the placement seat 31, the end of the retainer 383 contacting the end of the nut 381, a spring piece 384 fixedly connected to one side of the retainer 383, the other side of the spring piece 384 fixedly connected to the inner wall of the placement seat 31, a first pull rope 385 fixedly connected to one side of the retainer 383, and the other end of the first pull rope 385 passing through the placement seat 31 and fixedly connected to a pull block 33.

[0026] Using an electric wrench or other specialized tools, thread the nut 381 onto the screw 382, ​​so that the top of the nut 381 abuts against the end of the placement seat 31, thereby fixing the wire clamp 32 onto the placement seat 31, thus providing stable contact with the cable. At this time, loosen the pull block 33, and the elastic force of the spring piece 384 pushes the abutment 383 to move, so that the end of the abutment 383 contacts the end of the nut 381, thereby limiting the downward movement of the nut 381.

[0027] like Figure 3 As shown, a second pull rope 386 is fixedly connected to one side of one of the rubber blocks 36, and the other end of the second pull rope 386 passes through one of the sliding frames 34 and the pressure seat 32 and is fixedly connected to a connecting block 387.

[0028] Pull the connecting block 387 upward, and the upward movement of the connecting block 387 will drive the second pull rope 386 to move. The movement of the second pull rope 386 will drive the corresponding rubber block 36 to retract into the corresponding slide frame 34, so that the wire pressing seat 32 can be pressed against the cable. Then, loosen the connecting block 387, and the elastic force of the spring 35 and the elastic rod 37 will push the rubber block 36 to move and contact the cable.

[0029] like Figure 3 As shown, a reinforcing frame 1 is fixedly connected to the bottom of the placement base 31, and the surface of the reinforcing frame 1 is slidably connected to the inner wall of the mounting frame 2.

[0030] In use, the inner wall of the wire clamp 32 is pressed against the cable. The connecting block 387 is pulled upwards, and the upward movement of the connecting block 387 causes the corresponding rubber block 36 to retract into the corresponding sliding frame 34 via the second pull rope 386, thus pressing the wire clamp 32 against the cable. Then, the connecting block 387 is loosened, and the elastic force of the spring 35 and the elastic rod 37 pushes the rubber block 36 to move and press against the cable surface. Using an electric wrench or other special tools, the nut 381 is threaded onto the screw 382, ​​so that the top of the nut 381 presses against the end of the placement seat 31, thereby fixing the wire clamp 32 on the placement seat 31 and providing stable pressure against the cable. At this time, the pull block 33 is loosened, and the elastic force of the spring 384 pushes the abutment 383 to move, so that the end of the abutment 383 contacts the end of the nut 381, thereby limiting the downward movement of the nut 381.

[0031] It should be noted that the reinforcing frame 1, mounting frame 2, placement seat 31, wire clamp seat 32, spring 35, elastic rod 37, screw 382, ​​nut 381 and spring piece 384 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
