Description

Technical Field

[0001] The utility model relates to the field of cable testing, in particular to a testing device for copper core cables. Background Technique

[0002] A cable is a wire used to transmit electric power or communication signals, consisting of one or more electrical conductors. Usually, a cable also includes an insulating layer and an external protective layer to prevent electrical interference or mechanical damage. Cables are widely used in buildings, power systems, communication networks, and various electronic devices.

[0003] However, there are still deficiencies in view of this patent. Although a certain testing effect of the hardness of the internal copper wire of the cable can be achieved during use, the defects are as follows: the existing cable detection device lacks a convenient fixed detection effect for adapting to various models and sizes of cables, resulting in easy deviation during cable detection, affecting the detection accuracy. In view of this, we have proposed a testing device for copper core cables to solve the above problems. Summary of the Utility Model

[0004] 1. Technical Solution

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions.

A U-shaped frame is fixed to the upper end of the bottom plate, a mounting frame is fixed to the upper end of the U-shaped frame, a hydraulic rod is arranged at the lower end of the mounting frame, a connecting plate is fixedly installed on the surface of the hydraulic rod, a limiting rod is movably inserted on one side of the connecting plate, and a limiting block is movably connected to the upper end of the bottom plate;

[0007] When this device is in use, the cable to be detected can be placed on the upper end of the through hole one in the middle of the limiting block. The limiting block can adjust the moving positions on both sides by means of a linear motor to achieve the effect of adapting to cables with different diameters. After fixing the cable, adjust the variable on the controller to apply a preset amount to the hydraulic cylinder to press the cable downward. The hydraulic rod will leave a groove on the surface of the cable. During the downward movement of the hydraulic rod, the limiting rod on one side will also move downward, but the limiting rod moves relative to the connecting plate. After the limiting rod touches the cable, it will not press out a groove downward. Design a scale with the lower ends of the hydraulic rod and the limiting rod being flush as the zero point, and the depth of the groove can be read. The depth of the groove can be finally calculated through a series of conversions by a computer to calculate the hardness of the cable.

[0008] Preferably, a guide rail is welded to the upper end of the bottom plate, the limiting block is movably installed inside the guide rail, a linear motor is embedded and fixed on the outer wall of one side of the limiting block, and the linear motor is adapted to the guide rail;

[0009] Preferably, a base is fixed to the lower end of the base plate and is distributed in an annular array, and the opposite sides of the limiting blocks are designed to be arc-shaped;

[0010] Preferably, a through hole one is opened on the surface of the guide rail, and the through hole one penetrates through the base plate and the guide rail;

[0011] Preferably, a through hole two is opened on the surface of the mounting frame, and a handle is fixed to the upper end of the limiting rod, and the handle moves through the through hole two;

[0012] Preferably, a controller is embedded and fixed to the upper end of the mounting frame.

[0013] Preferably, a hydraulic cylinder is fixed to the upper end of the mounting frame, and the hydraulic rod is inserted into the interior of the hydraulic cylinder.

[0014] Compared with the prior art, the advantages of the present utility model are as follows:

[0015] First, the present utility model can be zeroed at the level of the surface of the hydraulic rod and the limiting rod, and a scale is designed to manually read the depth of the detection groove by using the height difference.

[0016] Second, based on the beneficial effect one, the device can use a linear motor to drive the limiting block to fix the cable adaptively to ensure that the cable does not move during detection.

[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all of the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] When using this device, the cable to be detected can be placed on the upper end of the through hole 15 in the middle of the limit block 14. The limit block 14 can adjust the moving positions on both sides by means of the linear motor 3 to achieve the effect of adapting to cables of different diameters. After fixing the cable, adjust the variable on the upper end of the controller 9 to apply a preset amount to the hydraulic cylinder 11 to press down the cable. The hydraulic rod 13 will leave a groove on the surface of the cable. During the downward movement of the hydraulic rod 13, the limit rod 6 on one side will also move downward, but the limit rod 6 moves relative to the connecting plate 7.
