Description

Technical Field

[0001] The utility model relates to the technical field of helicopter electrical system detection equipment, in particular to a helicopter electrical control box tester with strong applicability. Background Art

[0002] The electronic equipment of helicopters generally uses special connectors (such as round aviation plugs) to output to the outside in the form of pins or holes. The specifications of the pins / holes are inconsistent, and the probes of test equipment (multimeters, oscilloscopes, etc.) sometimes cannot match the signal pins of the cable.

[0003] For example, the patent document with application number 201820397013.0 discloses a helicopter electrical control box tester with strong applicability. The utility model discloses a helicopter electrical control box tester with strong applicability, which has a shell, a detection main part is arranged inside the shell, and a detection probe is arranged outside the shell. The detection probe is electrically connected to the detection main part through a wire. The utility model is characterized in that a plurality of part placement holes are arranged on the shell, and a detection probe is placed in each part placement hole; the hole shape of the part placement hole matches the shape of the detection end of the detection probe, and the detection end face of the detection probe is provided with a first magnetic part, and one end face of the detection probe is provided with a second magnetic part. Compared with the prior art, the utility model can replace the detection probe simply and quickly, simplify the replacement process, and save replacement time. However, when replacing the detection needle of the detection pen, the helicopter electrical control box tester with strong applicability needs to hold the detection pen with one hand and hold the detection needle with the other hand to install it. If used improperly, the detection needle will fall and be damaged. At the same time, when the arm needs to rest for a long time of detection, the detection pen cannot be temporarily placed in a suitable position.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a helicopter electrical control box tester with strong applicability is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 2 As shown, a helicopter electrical control box tester with strong applicability includes a connecting wire 2 installed on the two side surfaces of the tester body 1, and a detection probe 201 is arranged at the front end of the connecting wire 2, and a detachable detection probe 205 is arranged at the front end of the detection probe 201, and the detachable detection probe 205 is connected to the detection probe 201 by magnetic attraction. This setting is an existing device and will not be elaborated in detail.

[0022] Furthermore, a positive magnetic block 202 is installed at the lower end of the detection probe pen 201, and a guide block 203 is provided at the lower end of the positive magnetic block 202, and negative magnetic material blocks 204 are provided on both sides of the upper end surface of the tester main body 1, and the negative magnetic material block 204 is magnetically connected to the positive magnetic block 202. The advantage of this arrangement is that, through the setting of the positive magnetic block 202, the detection probe pen 201 can be adsorbed and fixed when the detachable detection detection needle 205 is replaced, which facilitates the replacement of the probe. At the same time, the detection probe pen 201 can also be temporarily adsorbed on the surface of the tester main body 1 during detection to reduce the fatigue of the detection personnel. Through the setting of the guide block 203, the positive magnetic block 202 can be stably adsorbed with the negative magnetic material block 204.

[0023] Furthermore, an anti-drop handle 206 is installed on the upper surface of the tester body 1. The advantage of this arrangement is that the anti-drop handle 206 can prevent the detection probe 201 from slipping when in use.

[0024] like Figure 3-Figure 4 As shown, the lower surfaces of both sides of the tester body 1 are provided with slide grooves 302, and the inner part of the slide grooves 302 is slidably installed with limit blocks 301. The advantage of this arrangement is that the movement of the protective plate 3 can be controlled and limited by the arrangement of the slide grooves 302.

[0025] Furthermore, a protective plate 3 is provided at the rear end of the limit block 301, and the protective plate 3 is L-shaped. The advantage of this arrangement is that the tester body 1 can be protected by the setting of the protective plate 3 to prevent the tester body 1 from falling and causing damage to the tester body 1 when being carried and moved.

[0026] Furthermore, a shock-absorbing spring 303 is provided on the bottom surface of the protective plate 3, and a limiting telescopic rod 304 is installed inside the shock-absorbing spring 303, and the limiting telescopic rod 304 is provided on the bottom surface of the tester body 1. The advantage of this arrangement is that, through the arrangement of the shock-absorbing spring 303, the vibration impact brought by the protective plate 3 can be reduced by compression, and the impact on the tester body 1 can be reduced, which facilitates better carrying and improves the adaptability of the tester body 1.

[0027] Furthermore, a detection needle placement groove 4 is opened at the front end of the upper surface of the tester body 1, and a detachable detection detection needle 205 is installed inside the detection needle placement groove 4. The advantage of this arrangement is that through the setting of the detection needle placement groove 4, the detachable detection detection needle 205 can be placed inside the detection needle placement groove 4.

[0028] Furthermore, a slot 401 is provided in the middle of the upper surface of the tester body 1, and a rotating handle 402 is rotatably mounted on the inner wall of the slot 401. The advantage of this arrangement is that the tester body 1 can be easily carried and used by setting the rotating handle 402.

[0029] Working principle: When using the highly applicable helicopter electrical control box tester, first, after the detection probe 201 with the positive magnetic block 202 is adsorbed and fixed by the guide block 203 and the negative magnetic material block 204, the detachable detection probe 205 is taken out from the inside of the probe placement slot 4, and it is adsorbed on the front end of the detection probe 201 to complete the installation. Then, the detection probe 201 is picked up through the anti-drop handle 206 to test the electrical control box of the helicopter. If it is accidentally dropped during the transfer of the tester body 1, the protective plate 3 contacts the ground, and the protective plate 3 drives the front limit block 301 to slide along the slide groove 302, and the vibration generated by the vibration is compressed and buffered by the shock-absorbing spring 303, reducing the impact and vibration of the tester body 1. This is the working principle of the highly applicable helicopter electrical control box tester.
