[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, a cable fault tester according to one embodiment of the present invention includes: a base plate 1, wherein a plurality of casters 101 are mounted on the bottom of the base plate 1;

[0023] Rotating plate 2, the rotating plate 2 is rotatably installed on the top of the base plate 1, and an mounting plate 3 is fixedly installed on one side of the rotating plate 2. A sliding sleeve plate 4 is slidably sleeved on the mounting plate 3. A box 5 is fixedly installed on the bottom of the sliding sleeve plate 4. The tester body is installed inside the box 5.

[0024] Rotating assembly 6, which is mounted on the base plate 1, is used to drive the rotating plate 2 to rotate;

[0025] Fixing component 7 is installed on the sliding sleeve 4 and is used to fix the position of the sliding sleeve 4.

[0026] When the tester needs to be operated, the device can be pushed to the designated position using the moving wheels 101. Once there, the rotating component 6 is activated, which drives the rotating plate 2 to rotate to a vertical position. Since a mounting plate 3 is installed on one side of the rotating plate 2, and a sliding sleeve plate 4 is slidably fitted on the mounting plate 3, and a housing 5 is fixed to the bottom of the sliding sleeve plate 4, when the rotating plate 2 is vertical, it also drives the housing 5 to be vertical. Then, the housing 5 is pulled upwards, which drives the sliding sleeve plate 4 to move upwards, so that the mounting plate 3 gradually moves out of the sliding sleeve plate 4. When the housing 1 moves to the designated height suitable for testing high-altitude cables, the fixing component 7 can be used to fix the position between the mounting plate 3 and the sliding sleeve plate 4 to ensure the stability of the overall structure. Then, the housing 5 is opened, and the tester inside is used to perform fault detection on the cable.

[0027] This invention allows the device to be easily moved to a designated position via the movable wheels 101, greatly improving its mobility. The rotating component 6 drives the rotating plate 2 to rotate, making the housing 5 vertical and facilitating adjustment of the device's orientation. When inspecting cables at height, pulling the housing 5 upwards moves the sliding sleeve 4, allowing for flexible adjustment of the inspection height. The fixing component 7 secures the mounting plate 3 and the sliding sleeve 4, ensuring stability during the inspection process. This series of designs avoids requiring workers to hold the device for extended periods, effectively reducing labor intensity and preventing accidental drops that could cause injury or damage, thus ensuring the safety of both personnel and equipment.

[0028] like Figure 1 As shown, in some embodiments, the rotating assembly 6 includes a long plate 61 fixedly installed at the bottom of the base plate 1, an electric push rod 62 rotatably installed on the long plate 61, and a connecting plate 63 rotatably installed on one side of the rotating plate 2, the connecting plate 63 being rotatably connected to the telescopic end of the electric push rod 62.

[0029] The electric actuator 62, mounted on the long plate 61, is activated, and its telescopic end begins to extend. Since the telescopic end of the electric actuator 62 is rotatably connected to the connecting plate 63 mounted on one side of the rotating plate 2, the extension of the telescopic end of the electric actuator 62 causes the connecting plate 63 to move, thereby causing the rotating plate 2 to rotate to a vertical position. Because a mounting plate 3 is fixedly mounted on one side of the rotating plate 2, and a sliding sleeve 4 is slidably fitted on the mounting plate 3, with the housing 5 fixedly mounted at the bottom of the sliding sleeve 4, the housing 5 also becomes vertical as the rotating plate 2 becomes vertical.

[0030] like Figure 2As shown, in some embodiments, the fixing component 7 includes a fixing frame 71 fixedly installed on the top of the sliding sleeve plate 4. A pull rod 72 is slidably inserted into the fixing frame 71. A fixing plate 73 is fixedly installed at one end of the pull rod 72. A return spring 74 is fixedly installed between the top of the fixing plate 73 and the top of the inner wall of the fixing frame 71. The mounting plate 3 has multiple positioning grooves. The fixing plate 73 passes through the fixing frame 71 and is inserted into one of the positioning grooves.

[0031] Adjust the height of the enclosure 5. First, pull the lever 72 fixed to the top fixing frame 71 of the sliding sleeve 4. The lever 72 moves the fixing plate 73. At this time, the return spring 74 between the top of the fixing plate 73 and the top of the inner wall of the fixing frame 71 is compressed, and the fixing plate 73 disengages from the positioning groove on the mounting plate 3. Then, pull the enclosure 5 upward to move it upward, thereby moving the sliding sleeve 4 upward, so that the mounting plate 3 gradually moves out of the sliding sleeve 4. When the enclosure 5 moves to the specified height suitable for detecting high-altitude cables, release the lever 72. Under the action of the return spring 74, the fixing plate 73 moves and inserts into the positioning groove of the corresponding position on the mounting plate 3, fixing the position between the mounting plate 3 and the sliding sleeve 4.

[0032] like Figure 2 As shown, in some embodiments, one side of the fixing plate 73 is constructed with an arc surface, which contacts the inner wall of the positioning groove.

[0033] One side of the fixing plate 73 has an arc surface. This arc surface will first contact the inner wall of the positioning groove and produce a certain guiding effect, which can more smoothly guide the fixing plate 73 to be accurately inserted into the positioning groove of the corresponding position of the mounting plate 3, fix the position between the mounting plate 3 and the sliding sleeve plate 4, and ensure the stability of the overall structure. In addition, the arc surface can facilitate the fixing plate 73 to automatically enter the fixing frame 71 under the pushing force, without the need for the operator to pull the lever 72, thus saving some labor.

[0034] like Figure 1 As shown, in some embodiments, two positioning plates 8 are symmetrically distributed at the bottom of the base plate 1, and the two ends of the two positioning plates 8 are fixedly installed with the moving wheels 101, and the top of the base plate 1 is fixedly installed with a handrail 9.

[0035] Pulling the handle 9, along with the moving wheels 101, pushes the base plate 1, allowing the device to be moved to a designated position. The operation is simple and convenient.

[0036] like Figure 3As shown, in some embodiments, two buffer frames 10 are symmetrically distributed and fixedly installed at the bottom of the base plate 1, and two positioning plates 8 are respectively inserted into the two buffer frames 10. A damper 11 is fixedly installed between the top of the positioning plate 8 and the top of the inner wall of the buffer frame 10, and a buffer spring 12 is fixedly installed between the top of the positioning plate 8 and the top of the inner wall of the buffer frame 10.

[0037] When this device is pulled onto a bumpy surface, in order to prevent the internal parts of the device from being damaged by frequent vibration, the rebound force generated by the compression of the buffer spring 12 can be used in conjunction with the damper 11 to produce a buffering and shock absorption effect, thereby reducing the vibration frequency and amplitude and preventing damage to electrical components.

[0038] like Figure 4 As shown, in some embodiments, the box body 5 includes two half-box frames 51, which are symmetrically distributed and rotatably installed on the bottom of the rotating plate 2. Magnets 52 are fixedly installed on adjacent sides of the two half-box frames 51, and the opposite poles of the two magnets 52 attract each other.

[0039] When the tester body is not in use, the two half-box frames 51 are joined together, and the open surface of the half-box frame 51 is attached to the top of the base plate 1, so that the half-box frame 51 is in a tight closed state, which is not easy to open at will, and even if it is dropped, it is not easy to be opened and damaged.

[0040] like Figure 4 As shown, in some embodiments, both of the half-box frames 51 are provided with heat dissipation holes, and a filter screen 13 is fixedly installed at the heat dissipation holes of the half-box frames 51.

[0041] The back of the tester body faces the top of the housing 5. This arrangement allows heat to dissipate directly upwards, facilitating heat dissipation for electrical components. Additionally, a filter 13 is installed to prevent dust from entering the housing.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
