BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 The figure is a schematic diagram of the structure of a portable clamp for cable protection.

[0011] Figure numerals: 1 - first rigid protective body, 2 - fastening device, 3 - fixing clamp, 4 - foldable rubber protective sleeve, 5 - second rigid protective body. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0013] The principle of the present invention is: the foldable rubber protective sleeve 4 provides effective protection for the cable, so that the cable insulation layer is not subject to friction; the fastening device 2 is used to fix the clamp of the present invention and the cable in a suitable position to prevent the clamp from falling off from a high place; the rigid protective body is used as the main body device to effectively fix the fastening device 2 and the cable; the fixing clamp 3 fixes the entire cable bundle to the external equipment to eliminate the stress to the greatest extent.

[0014] like Figure 1As shown, a portable clamp for cable protection includes a fastening device 2, a rigid protective body, a foldable rubber protective sleeve 4 and a fixing clamp 3. The rigid protective body is a circular ring structure as a main frame, including a first rigid protective body 1 at the top and a second rigid protective body 5 at the bottom. A foldable rubber protective sleeve 4 is connected between the first rigid protective body 1 and the second rigid protective body 5. The rigid protective body and the foldable rubber protective sleeve 4 form a tubular structure that is sleeved on the outside of the cable. The foldable rubber protective sleeve 4 is a corrugated tube with telescopic and bending functions. The fastening device 2 is threadedly connected to the side wall of the rigid protective body. The fastening device 2 fixes the clamp to the part of the cable that needs to be protected. The fixing clamp 3 is connected to the side wall of the first rigid protective body 1. The cable is connected and fixed to the external equipment through the fixing clamp 3.

[0015] like Figure 1 As shown, the fastening device 2 is a cylinder with external threads. Generally, two or three fastening devices 2 form a group. Two groups of fastening devices 2 are evenly distributed along the outer circumference of the first rigid protective body 1 and the second rigid protective body 5 in groups. The ends of the fastening devices 2 penetrate the side walls of the rigid protective bodies. One end of the fastening device 2 is provided with a convex end that is convenient for manual rotation. The cross-section of the convex end is a regular polygon or a circle, which is convenient for manual application of torsional force to the fastening device 2. The other end of the fastening device 2 penetrates the side wall of the rigid protective body and presses on the insulation layer of the cable. The cable is clamped in the clamp by multiple fastening devices 2 in the same group. The end face of the fastening device 2 that contacts the cable is attached with an elastic gasket, which can play a role in preventing slipping and damaging the cable while clamping the cable.

[0016] like Figure 1 As shown, there are two fixing clamps 3 symmetrically arranged on the side wall of the first rigid protective body 1. The fixing clamp 3 includes a fixing part and a clamp part. The fixing part and the clamp part are connected by a connecting rod shaft, so that the clamp part can rotate around the shaft connected thereto. One end of the fixing part is fixed to the side wall of the first rigid protective body 1, and the other end is connected to the connecting rod, so that the connecting rod can also rotate around the shaft connected thereto, providing a larger range of motion for the clamp part to facilitate connection and fixation with the equipment. The clamp part is a circular ring with a notch, and the notch is connected by a hand screw. The length of the first rigid protective body 1 is greater than that of the second rigid protective body 2. The fastening device 2 and the fixing clamp 3 on the first rigid protective body 1 are arranged up and down along the axial direction. The fixing clamp 3 is located at the end closer to the foldable rubber protective sleeve 4. This structural layout is more conducive to the fixing clamp 3 being close to the center of gravity of the clamp, so that the fixing effect is better.

[0017] When in use, the clamp is put on the cable and moved to the part of the cable that needs to be protected, so that the protected part of the cable is located in the foldable rubber protective sleeve 4, and then the fastening devices 2 on the upper and lower sides are tightened to clamp the clamp and the cable, and then the clamp is connected and fixed to the nearby external equipment that can be used for fixed connection through the fixing clamp 3, so as to eliminate the stress on the cable to the greatest extent.

[0018] The above are specific embodiments of the present invention and the technical principles used. Any modifications and equivalent changes based on the technical solution of the present invention should be included in the protection scope of the present invention.
