[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Figure 1 The following is a schematic diagram showing the structure of the multi-threaded electric test hook in the utility model. Figure 2 It is a cross-sectional view of the multi-threaded test hook in the present invention, which includes: a test hook body 1 and a tester body 2. The test hook body 1 is installed above the tester body 2, and the test hook body 1 is inserted into the tester body 2.

[0026] The test hook body 1 includes a first sub-test hook 11, a second sub-test hook 12, and a third sub-test hook 13. The first sub-test hook 11 is rotatably connected to the test hook body 2, the second sub-test hook 12 is fixedly connected to the test hook body 2, and the third sub-test hook 13 is rotatably connected to the test hook body 2. The test hook body 2 is internally provided with a test circuit, which is electrically connected to the test hook body 1. The test hook body 1 is used to be hung on a corresponding cable, so that the current on the cable can be conducted to the test hook body 2 through the test hook body 1. The test circuit is used to detect whether there is a discharge on the corresponding cable.

[0027] It should be noted that when the main body of the test hook is testing parallel cables, it can only test the discharge conditions of two cables at the same time, that is, the first sub-test hook and the third sub-test hook are used to detect parallel cables; when the main body of the test hook is testing non-parallel cables, it can test the discharge conditions of three cables at the same time, that is, all three sub-test hooks can detect cables.

[0028] Furthermore, the electrical test hook body 1 is provided with a locking mechanism 3, which includes: one or more limit bosses, a drive motor, and a lifting switch. The limit bosses are connected to the output end of the drive motor, and the lifting switch is electrically connected to the drive motor. The drive motor is used to move the one or more limit bosses to a specified position; the lifting switch is used to control the working direction of the drive motor. The lifting switch includes an upshift and a downshift. The upshift is used to control the drive motor to move the limit boss upward, and the downshift is used to control the drive motor to move the limit boss downward.

[0029] Specifically, when the lifting switch is switched from downshift to upshift, the lifting switch generates a first electrical signal and sends it to the drive motor. After the drive motor receives the first electrical signal, the output end of the drive motor moves upward, thereby driving the limit boss to move upward; similarly, when the lifting switch is switched from upshift to downshift, the lifting switch generates a first electrical signal and sends it to the drive motor. After the drive motor receives the second electrical signal, the output end of the drive motor moves downward, thereby driving the limit boss to move downward.

[0030] Furthermore, the end surface of any of the limiting bosses is recessed inward to form an arc-shaped limiting boss, and a rubber pad is provided on the arc surface formed by the inward recess of any of the limiting bosses. The upper end surface of the limiting boss forms an arc surface for fitting the surface of the cable, so that the limiting boss can abut against the corresponding cable, thereby limiting the movement of the cable toward the limiting boss, ensuring that the cable can be confined within the circular space formed by the limiting boss and the test hook. The rubber pad is provided on the arc surface of the limiting boss. The rubber pad has good elasticity. When the end surface of the limiting boss abuts against the cable, the rubber pad deforms, making the rubber pad fit the outer surface of the cable, increasing the friction between the rubber pad and the cable, and facilitating the relative stationary state of the test hook and the cable. Secondly, the rubber pad is relatively soft. When the rubber pad comes into contact with the cable, the rubber pad deforms, reducing the wear of the cable surface due to scratches, and effectively reducing the risk of wear between the limiting boss and the cable.

[0031] Furthermore, the limiting boss includes a first limiting boss 31, a second limiting boss 32, and a third limiting boss 33, wherein the first limiting boss 31 is correspondingly arranged on the first sub-test hook 11, the second limiting boss 32 is correspondingly arranged on the second sub-test hook 12, and the third limiting boss 33 is correspondingly arranged on the third sub-test hook 13. In this embodiment, each of the limiting bosses is correspondingly arranged on a sub-test hook, and each sub-test hook temporarily limits the cable to be tested to the circular space formed by the limiting boss and the sub-test hook, so as to prevent the cable from being separated from the test hook during the testing process, resulting in inaccurate testing, thereby ensuring the accuracy of the test hook in testing the cable.

[0032] Furthermore, the first sub-test hook 11 is driven to rotate by an external force, and the rotation angle of the first sub-test hook 11 is less than 180°; the third sub-test hook 13 is driven to rotate by an external force, and the rotation angle of the third sub-test hook 13 is less than 180°. The first sub-test hook 11 rotates at different angles, which enables the first sub-test hook 11 to adjust its movement posture and angle to adapt to different working environments; the third sub-test hook 13 rotates at different angles, which enables the third sub-test hook 13 to adjust its movement posture and angle to adapt to different working environments. When the first sub-test hook 11 and the third sub-test hook 13 rotate at different angles, and the first sub-test hook 11, the second sub-test hook 12, and the third sub-test hook 13 are oriented in different directions, the test hooks can test multiple cables simultaneously, thereby improving the efficiency of cable detection.

[0033] Furthermore, the inspection circuit is connected to an alarm light 4, which includes a first alarm light 41, a second alarm light 42, and a third alarm light 43. The first alarm light 41 is electrically connected to the first sub-test hook 11, the second alarm light 42 is electrically connected to the second sub-test hook 12, and the third alarm light 43 is electrically connected to the third sub-test hook 13. Each alarm light 4 corresponds to a sub-test hook. When the test hooks are simultaneously inspecting three different cables, if one or more of the cables is discharging, the sub-test hook corresponding to that cable will conduct current to the inspection circuit, causing the corresponding alarm light 4 to illuminate. The amount of discharge in the cable directly affects the brightness of the corresponding alarm light 4. Specifically, when a cable carries a large current, the alarm light will illuminate brightly, while when a cable carries a small current, the alarm light will illuminate dimmer, thereby alerting the operator to the current level in the corresponding cable. When there is no current on the corresponding cable, no current passes through the inspection circuit inside the electroscope body 2, and the alarm 5 and the alarm light 4 do not respond, and the staff can proceed to the next step.

[0034] Furthermore, the inspection circuit is provided with an alarm 5, which is electrically connected to the alarm light 4. The alarm 5 is used to sound an alarm to alert personnel that the cable being tested by the electrical test hook has discharged. The alarm 5 is connected in series with the alarm light 4. Since the first alarm light 41, the second alarm light 42, and the third alarm light 43 are connected in parallel, when at least one of the three alarm lights 4 illuminates, the alarm 5 will sound an alarm to alert personnel.

[0035] Specifically, when the test hook simultaneously tests multiple cables, that is, one sub-test hook tests one cable, if one of the cables is discharged, the alarm 5 will sound an alarm; when the test hook tests one cable, that is, three sub-test hooks are hung on the same cable, if this cable is discharged, the alarm 5 will sound an alarm.

[0036] Furthermore, the top of the test hook body 1 is provided with one or more fixing holes, each of which is inserted with a rubber T-shaped platform. In this embodiment, the top of the test hook body 1 is provided with two fixing holes, one located at the top of the first sub-test hook 11 and the other at the top of the third sub-test hook 13. The rubber T-shaped platform is used to rotate the corresponding sub-test hook, preventing workers from directly contacting the test hook body 1 and causing electric shock, reducing the risk of accidents and improving the user experience of the test hook.

[0037] Furthermore, an extension rod 6 is provided at the bottom of the electroscope body 2, and its surface is provided with an insulating coating. The user can apply force to the electroscope hook through the extension rod 6, enabling the hook to effectively contact the cable and thus stably detect whether the corresponding cable is experiencing discharge. Furthermore, the insulating coating on the extension rod 6 improves electrical insulation performance, prevents current leakage, and avoids electrical accidents, thereby protecting user safety and improving the user experience.

[0038] Furthermore, the electroscope body 2 is made of plastic. In this embodiment, the electroscope body 2 is made of polypropylene (PP). Polypropylene (PP) has excellent insulation properties, effectively isolating electromagnetic fields and currents, protecting the safety and stability of the test circuit within the electroscope body 2. Furthermore, polypropylene (PP) has excellent mechanical properties and can withstand significant impact forces. When the electroscope body 2 collides with other hard objects, the surface of the electroscope body 2 remains unaffected, effectively protecting the internal components of the electroscope.

[0039] To sum up, the utility model divides the main body of the test hook into three sub-test hooks, and the first sub-test hook and the third sub-test hook rotate to adjust their directions, so that the first sub-test hook, the second sub-test hook and the third sub-test hook can simultaneously test cables from different directions or test the same cable at the same time, thereby improving the flexibility of the test hook in testing cables and thus improving the detection efficiency of the test hook.
