[0004] In actual use of the prior art, since different cables are distributed in different locations and their surrounding environments are also different, when the surrounding environment of the cable is dim due to the obstruction of trees and buildings, it is difficult for the operator to see the control panel and display screen of the detector, which affects the reading and analysis of the test data and causes errors in the test data. Therefore, a cable environmental suitability tester is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Example 1

[0027] Reference Figure 1 , Figure 2 and Figure 4 , which is the first embodiment of the utility model, and provides a cable environmental suitability tester, including an instrument box 1 and a cable tester 101, wherein the cable tester 101 is arranged in the inner cavity of the instrument box 1, a box cover 102 is hingedly connected to the upper surface of the instrument box 1, an adjustment mechanism 2 is arranged on the outer surface of the instrument box 1, and an illumination mechanism 3 is arranged in the inner cavity of the box cover 102;

[0028] The adjustment mechanism 2 includes four arc-shaped plates 201 fixedly connected to the outer surface of the instrument case 1, a support pad 202 is movably connected to the lower surface of the instrument case 1, and an electric push rod 203 is fixedly connected to the top of the inner cavity of the arc-shaped plate 201;

[0029] Specifically, a handle 103 is hinged on one side of the instrument case 1, a buckle 104 is provided on one side of the instrument case 1 and the case cover 102, a rubber pad is fixedly connected to the lower surface of the support pad 202, and the lower end of the electric push rod 203 is fixedly connected to the upper surface of the support pad 202.

[0030] Furthermore, the operator can use the handle 103 to easily move the entire device to different positions to test different cables. The instrument case 1 and the box cover 102 are fixed together by the buckle 104 to protect the cable detector 101 inside to avoid damage caused by impact, thereby improving the safety of the device. When the cable needs to be tested, the buckle 104 is opened and the box cover 102 is rotated upward to a vertical state. At this time, the limit rod 307 and the fixing ring 308 are driven by the elastic force of the limit spring 310 to move upward and insert into the inside of the box cover 102 to fix and limit the box cover 102, so that it remains in a vertical state to avoid shaking during testing and affecting the operator's operation. Then, a known current is applied to both ends of the conductor through the cable detector 101, and then the test is performed. The voltage drop generated can be used to calculate the resistance of the conductor and evaluate whether the conductor resistance of the cable is within the normal range. The display screen on the cable tester 101 can be used to provide the user with test data and judge the test results. During the test, when the surrounding environment is dim and unclear due to the obstruction of trees and buildings, the plug rod 303 is moved downward to drive the spring 305 to extend upward. When the plug rod 303 leaves the inner cavity of the rotating rod 301, the rotating rod 301 loses its fixed limit and can rotate to drive the lighting lamp 302 to move above the cable tester 101 to illuminate the cable tester 101, so as to avoid the operator having difficulty in seeing the control panel and display screen of the tester due to the dim environment, thereby affecting the reading and analysis of the test data and causing errors in the test data.

[0031] Example 2

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and the inner cavity of the box cover 102 is provided with a lighting mechanism 3;

[0033] The lighting mechanism 3 includes a rotating rod 301 hinged on the top of the inner cavity of the box cover 102, an illuminating lamp 302 is arranged on the upper surface of one end of the rotating rod 301, an insert rod 303 is inserted into the inner cavity of the rotating rod 301, a round handle 304 is fixedly connected to the lower end of the insert rod 303, a spring 305 is sleeved on the outer surface of the insert rod 303, a fixing plate 306 is fixedly connected to the top of the inner cavity of the box cover 102, a limiting rod 307 is inserted into the inner cavity of the box cover 102, a fixing ring 308 is fixedly connected to the outer surface of the limiting rod 307, a limiting spring 310 is sleeved on the outer surface of the limiting rod 307, and a limiting plate 309 is fixedly connected to one side of the instrument box body 1;

[0034] Specifically, the outer surface of the insertion rod 303 is movably connected to the inner cavity of the fixing plate 306, one end of the spring 305 is fixedly connected to the fixing plate 306, the end of the spring 305 away from the fixing plate 306 is fixedly connected to the round handle 304, the outer surface of the limiting rod 307 is movably connected to the inner cavity of the limiting plate 309, one end of the limiting spring 310 is fixedly connected to the fixing ring 308, and the end of the limiting spring 310 away from the fixing ring 308 is fixedly connected to the limiting plate 309.

[0035] Further, the operator starts the electric push rod 203 to drive the support pad 202 to move downward and support the ground. The operator can control the support height of the four support pads 202 according to the ground conditions to ensure that the device is in a stable state to avoid shaking that affects the detection effect.

[0036] Working principle: During the use of the device, the operator can use the handle 103 to easily move the device as a whole to different positions to test different cables. The instrument case 1 and the box cover 102 are fixed together by the buckle 104 to protect the cable tester 101 inside to avoid damage caused by impact, thereby improving the safety of the device. When the cable needs to be tested, the buckle 104 is opened and the box cover 102 is rotated upward to a vertical state. At this time, the limit rod 307 and the fixing ring 308 are driven by the elastic force of the limit spring 310 itself to move upward and insert into the box cover 102 to fix the box cover 102 to keep it vertical to avoid shaking during testing and affect the operator's operation. Then, a known current is applied to both ends of the conductor through the cable tester 101, and the resulting voltage drop is measured. The resistance of the conductor can be calculated to evaluate whether the conductor resistance of the cable is within the normal range, and the cable tester 101 can be used to determine whether the conductor resistance of the cable is within the normal range. The display screen on the cable detector 101 provides the user with test data and judges the test results. During the test, when the surrounding environment is dim and unclear due to the obstruction of trees and buildings, the rod 303 is moved downward to drive the spring 305 to extend upward. When the rod 303 leaves the inner cavity of the rotating rod 301, the rotating rod 301 loses its fixed limit and can rotate to drive the lighting lamp 302 to move above the cable detector 101 to illuminate the cable detector 101, so as to avoid the operator having difficulty in seeing the control panel and display screen of the detector due to the dim environment, thereby affecting the reading and analysis of the test data and causing errors in the test data. When the ground is uneven and causes shaking during the test, the operator starts the electric push rod 203 to drive the support pad 202 to move downward and support the ground. The operator can control the support height of the four support pads 202 according to the ground conditions to ensure that the device is in a stable state to avoid shaking that affects the detection effect.
