[0018] In order to make the technical solutions of the present utility model clearer and more understandable, the present utility model will be further described below in conjunction with the specific embodiments of the drawings.

[0019] As Figures 1-3 shown, an automatic limiting and fixing device for an intermediate joint of a cable accessory according to an embodiment of the present utility model includes a base 1. At both ends of the upper surface of the base 1, fixing bolts 11 are symmetrically provided. On the side of the fixing bolts 11, mounting frames 2 are symmetrically provided. The mounting frame 2 is a hollow structure as a whole, and its inner surface is provided with a mounting frame sliding groove 21. Right below, a base sliding groove 12 is provided on the surface of the base 1. Inside the base sliding groove 12, base sliding blocks 13 are symmetrically and slidably connected. Inside the mounting frame sliding groove 21, mounting frame sliding blocks 22 are slidably connected. The mounting frame sliding blocks 22 and the base sliding blocks 13 are fixedly connected, and limiting support rods 3 are provided on their outer surfaces. A spring 14 is connected between the inner surface of the base sliding block 13 and the base sliding groove 12.

[0020] Among them, the limiting support rod 3 includes a first support rod 31 and a second support rod 32. The second support rod 32 is arranged on the outer surface of the first support rod 31 in the direction of the fixing bolt 11 to form a "Y" - shaped structure, and the height of the second support rod 32 is lower than that of the first support rod 31. During operation, the cable passes through between the first support rods 31 and drives them to deform, so that the second support rod 32 acts on the outer surface of the cable. Since the first support rod 31 and the second support rod 32 form a "Y" - shaped structure, when the second support rod 32 acts on the outer surface of the cable, a triangular structure can be formed with the first support rod 31 and the cable surface, which has a certain stability.

[0021] Among them, the whole limiting support rod 3 is made of rubber material. During operation, the rubber material has a certain toughness and good anti - slip performance. When the cable passes through between the first support rods 31 and drives them to deform, the first support rod 31 can better limit and fix the cable when it fits on the cable surface. At the same time, it can also prevent the cable from being damaged by colliding with the first support rod 31.

[0022] Among them, the outer surfaces of the mounting bracket 2 and the mounting bracket sliding block 22 are arc - shaped structures.

[0023] Among them, two groups of fixing bolts 11 are symmetrically arranged at both ends of the upper surface of the base 1. During operation, the present application is installed on the working equipment through the fixing bolts 11.

[0024] Among them, the base sliding block 13 and the inner surface of the base sliding groove 12 are connected by a spring 14. During operation, the cable passes through between the first support rods 31 under the tension generated by the spring 14 for preliminary limiting. As the stretching distance of the spring increases, the tension also gradually increases, enabling the first support rod 31 to better limit the cable.

[0025] Among them, eight limiting support rods 3 are arranged on the outer surfaces of the mounting bracket sliding block 22 and the base sliding block 13. During operation, the limiting support rods 3 are evenly distributed on the outer surfaces of the mounting bracket sliding block 22 and the base sliding block 13 in an annular structure, which can better limit and fix the cable.

[0026] Working principle: First, install this application on the operating equipment through the fixing bolt 11, and then start the operating equipment to drive the cable to move towards this application. When the cable contacts the first support rod 31, it will drive the mounting frame sliding block 22 and the base sliding block 13 to make a sliding displacement movement, and at the same time, it will drive the spring 14 to make a stretching movement. When the spring 14 is stretched, it will generate tension. Affected by the tension of the spring 14, the cable passes through between the first support rods 31, and it bends to fit the surface of the cable and deforms. Since the height of the second support rod 32 is lower than that of the first support rod 31, when the first support rod 31 bends, it will drive the second support rod 32 to act on the surface of the cable and form a triangular structure to limit it. When the cable drives the mounting frame sliding block 22 and the base sliding block 13 to slide to the maximum stroke distance, the mounting frame sliding groove 21 limits the mounting frame sliding block 22, and the cable continues to make a displacement movement to be connected to each other. At this time, the first support rod 31 bends to the maximum angle under the influence of the continuous displacement movement of the cable, and the pressure generated on the surface of the cable also gradually increases, so as to better limit and fix the whole cable.

[0027] The above embodiments can be combined with each other for further implementation under the condition of not being opposed to each other.

[0028] The above is only a preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
