[0015] 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.

[0016] Example 1 This embodiment provides a fixing clamping device for cable trenches in power engineering, such as... Figure 1-5 As shown, the cable trench fixing clamping device includes a support plate 1, and a placement frame 2 is installed on the front and on the upper and lower sides of the support plate 1. The placement frame 2 is equipped with a disassembly and assembly structure 3 through a T-slot 201, and a fixing structure 4 is installed on the disassembly and assembly structure 3. The fixed structure 4 includes a cable holder 41, a connecting frame 42 installed on the rear side of the end face of the cable holder 41, and a housing 43 disposed on the front side of the end face of the cable holder 41. A sleeve 44 is rotatably mounted on the connecting frame 42. An arc-shaped plate 45 is installed on the side wall of the sleeve 44. A connecting plate 46 is installed on the outer wall of the arc-shaped plate 45 away from the sleeve 44. Guide rods 47 are symmetrically installed in the inner cavity of the housing 43. A movable plate 48 is slidably mounted on the outer walls of the two sets of guide rods 47. A return spring 49 is installed on the movable plate 48 and on the outer wall of the guide rods 47. A baffle 410 is disposed on the end face of the movable plate 48. A pull rod 411 is installed on the end face of the baffle 410.

[0017] In use, first, place the cable inside the cable holder 41. Then, with one hand, the operator drives the pull rod 411 to move the baffle 410 away from the connecting frame 42, causing the baffle 410 to drive the movable plate 48 to slide on the two sets of guide rods 47 and press against the two sets of return springs 49. The baffle 410 is then fully inserted into the inner cavity of the housing 43. Then, with the other hand, the operator drives the arc plate 45 to rotate clockwise on the connecting frame 42, causing the inner wall of the arc plate 45 to wrap around and press the cable. At the same time, the bottom of the arc plate 45 contacts the end face of the cable holder 41. Finally, release the lever 411. Under the reset action of the two sets of return springs 49, the movable plate 48 is pushed in the opposite direction, moving the baffle 410 towards the connecting frame 42. This causes the bottom of the baffle 410 to move above the connecting plate 46 and press against it, thereby achieving the function of quickly clamping and fixing the cable. The installation and operation are convenient, greatly shortening the cable fixing and installation time. This avoids the problem that most existing cable trench fixing clamping devices use two sets of clamps and bolts to fix the cable, which is cumbersome and time-consuming. This improves the cable installation efficiency.

[0018] In this embodiment, two sets of mounting ears 5 are installed on the left and right side walls of the support plate 1, and rubber pads 412 are installed on the inner walls of the cable seat 41 and the arc plate 45; a sliding groove 4301 is opened on the end face of the housing 43, and the upper end of the pull rod 411 passes through the sliding groove 4301 and extends to the outside. Among them, by setting the rubber pad 412, the arc plate 45 and the cable seat 41 are flexibly connected to the outer wall of the cable through the rubber pad 412, which avoids the cable from being damaged by pressure and protects the cable. In this embodiment, multiple sets of T-slots 201 are provided, and the multiple sets of T-slots 201 are evenly distributed on the placement rack 2; the inner cavity of the housing 43 is connected to the end of the return spring 49 away from the movable plate 48, and the housing 43 is provided with a through groove that is adapted to the baffle 410. The housing 43 has a through groove that matches the baffle 410, which makes the connection between the baffle 410 and the housing 43 tighter and prevents the housing 43 from shaking. This makes the baffle 410 more firmly fixed to the end face of the connecting plate 46.

[0019] Example 2 Unlike embodiment 1, for this purpose, the disassembly and assembly structure 3 includes a T-shaped block 31 installed on the T-slot 201, a side plate 32 installed on the left side wall of the T-shaped block 31, and bolts 33 installed on the front and rear sides of the side plate 32 through through holes 3201. In use, when any set of fixing structures 4 on the placement rack 2 is damaged, the fixing structure 4 can be replaced individually. First, use a wrench to remove the two sets of bolts 33 from the two sets of threaded holes 202. Then, drive the side plate 32 to slide the T-block 31 out of the T-slot 201. The T-block 31 removes the damaged fixing structure 4. Then, replace the new fixing structure 4, T-block 31, and side plate 32. The side plate 32 drives the T-block 31 to slide into the T-slot 201. The T-block 31 with the fixing structure 4 is installed on the placement rack 2. Finally, use a wrench to install the two sets of bolts 33 and the side plate 32 on the two sets of threaded holes 202. This realizes the function of replacing the damaged fixing structure 4 individually, avoiding the situation where the entire fixing clamping device needs to be replaced due to the damage of a single fixing structure 4. This reduces the maintenance cost of the fixing clamping device and improves economic efficiency. In this embodiment, the T-block 31 and the T-slot 201 are adapted to each other, and the mounting bracket 2 has a threaded hole 202 corresponding to the bolt 33.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
