[0024] Please refer to Figures 1 to 5 The utility model embodiment provides a kind of power fittings with anticorrosion coating, the power fittings with anticorrosion coating includes mounting plate 1, bearing plate 2, abutting arc plate 4 and traction assembly 5.

[0025] In the embodiment of the utility model, please refer to Figure 1 And Figure 4 The bottom of mounting plate 1 is fixedly installed with vertically arranged bearing plate 2, and the mounting plate 1 and bearing plate 2 form L-shaped structure in cross section, and the rubber clamping pipe 3 for placing cable is fixedly embedded on the bearing plate 2, and a downward concave part 31 is arranged on the rubber clamping pipe 3, and the abutting arc plate 4 for pressing the cable in the lower concave part 31 is installed on the bearing plate 2 and is rotatably connected, specifically, the side of the abutting arc plate 4 is provided with a deflection hole 41, and the abutting arc plate 4 is rotatably connected with the rotating shaft 11 on the mounting plate 1 through the deflection hole 41, and the lower arc surface of the abutting arc plate 4 is fixedly installed with arc-shaped rubber compression pad 43;

[0026] The mounting plate 1 is also provided with traction assembly 5 for traction abutting arc plate 4 rotation.

[0027] It should be noted that: cable is inserted into rubber clamping pipe 3, so that the cable is preliminarily installed, and then the traction assembly 5 is used to drive the abutting arc plate 4 to rotate towards the lower concave part 31, so that the abutting arc plate 4 firmly presses the cable in the lower concave part 31, which greatly improves the effect of fixing the cable.

[0028] In addition, in order to improve the service life of the power fitting, ceramic filling coating is sprayed on the mounting plate 1, the bearing plate 2, the rubber clamping pipe 3, the abutting arc plate 4 and the arc-shaped rubber compression pad 43, and the ceramic filling coating can play a corrosion prevention effect, so that the service life of the power fitting is improved.

[0029] In the embodiment of the utility model, please refer to Figure 1 And Figure 4 The side end of the mounting plate 1 is provided with a threaded lug 12, and a threaded hole is formed in the threaded lug 12, the traction assembly 5 comprises a sliding rod 51, the sliding rod 51 is inserted into the threaded hole of the threaded lug 12 and is in sliding connection with the threaded hole, and threaded rods 52 and rod caps 55 are fixedly installed at both ends of the sliding rod 51, the threaded rod 52 is coaxially arranged with the sliding rod 51, and a curved intermediate link 53 is fixedly installed at the rod head of the threaded rod 52, a rotating joint 54 is fixedly installed at the rod head of the curved intermediate link 53, and the rotating joint 54 is in rotating connection with the traction head 42 fixedly installed at the top of the abutting arc plate 4.

[0030] It should be noted that when the cable is inserted into the rubber clamping pipe 3, the rear pull rod cap 55 makes the threaded rod 52 slide towards the threaded lug 12, and subsequent rotation of the rod cap 55 makes the threaded rod 52 rotate into the threaded hole of the threaded lug 12, so that the top of the abutting arc plate 4 is rotated around the rotating shaft 11 under the traction of the traction head 42, and thus the abutting arc plate 4 is compressed into the lower recess 31 and fastens the cable.

[0031] Further, the sliding rod 51 is sleeved with a tension spring 6, and rotating rings 61 are fixedly installed at both ends of the tension spring 6, the rotating ring 61 at one end of the tension spring 6 is in rotating connection with the end face of the threaded lug 12, and the rotating ring 61 at the other end of the tension spring 6 is in rotating connection with the rod cap 55, the tension spring 6 is arranged so that after the threaded rod 52 slides out of the threaded hole of the threaded lug 12, the sliding rod 51 can be driven to slide towards the rotating shaft 11 under the elastic force of the tension spring 6, so that the abutting arc plate 4 is driven to rotate around the rotating shaft 11 towards the threaded lug 12, and thus the distance between the lower recess 31 of the rubber clamping pipe 3 and the abutting arc plate 4 is increased, so that the cable can be placed into the lower recess 31 of the rubber clamping pipe 3.

[0032] The working principle of the power fitting with the corrosion-resistant coating provided by the utility model is as follows:

[0033] The cable is inserted into the rubber clamping pipe 3, thereby preliminarily installing the cable, and the traction assembly 5 is used to drive the abutting arc plate 4 to rotate towards the downward recess 31, so that the abutting arc plate 4 tightly presses the cable in the downward recess 31, thereby greatly improving the fixing effect of the cable. Specifically, after the cable is inserted into the rubber clamping pipe 3, the rear pull rod cap 55 makes the threaded rod 52 slide towards the threaded lug 12, and subsequent rotation of the rod cap 55 makes the threaded rod 52 rotate into the threaded hole of the threaded lug 12, so that the abutting arc plate 4 rotates around the rotating shaft 11 under the traction of the traction head 42, and the abutting arc plate 4 is pressed into the downward recess 31 and fastened to the cable. The pull spring 6 is arranged to make the threaded rod 52 slide out of the threaded hole of the threaded lug 12, and under the elastic force of the pull spring 6, the sliding rod 51 can be driven to slide towards the rotating shaft 11, so that the abutting arc plate 4 rotates around the rotating shaft 11 towards the threaded lug 12. Therefore, the distance between the downward recess 31 of the rubber clamping pipe 3 and the abutting arc plate 4 is increased, so that the cable can be placed in the downward recess 31 of the rubber clamping pipe 3. In order to improve the service life of the power fitting, ceramic filling coating is sprayed on the mounting plate 1, the bearing plate 2, the rubber clamping pipe 3, the abutting arc plate 4 and the arc-shaped rubber pressing pad 43, and the ceramic filling coating can prevent corrosion, thereby improving the service life of the power fitting.
