Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a diode detection device. Background Art

[0002] The existing testing equipment for testing diodes is generally a multimeter, which is generally connected to two test pens, one of which is red and the other is black. Set the multimeter to the buzzer diode position, connect the red pen to the positive pole of the diode, and the black pen to the negative pole of the diode. At this time, the forward resistance of the diode is measured, that is, the forward voltage drop of the diode. Different diodes have different forward voltage drop values ​​measured according to their internal materials. Test precautions: When using a digital multimeter to test a diode, connect the red test pen to the positive pole of the diode and the black test pen to the negative pole of the diode. The resistance value tested at this time is the forward resistance value of the diode, which is exactly the opposite of the test pen connection method of an analog multimeter.

[0003] When the existing detection equipment is used for testing, the diode is not fixed. Therefore, when the two detection pens touch the diode, the diode is prone to move, resulting in the detection pens sometimes not being able to contact the diode well when testing the diode. Therefore, the test results are relatively prone to problems. In addition, when the detection equipment is not in use, the detection pen has a wire, and if it is not organized and stored, the wire of the detection pen is prone to tangling.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] See Figures 1 to 12 .

[0028] A diode detection device includes a device body 1 and a diode 2, and a handle is installed on the device body 1; a detection pen 11 is inserted into the device body 1, and multiple fixing slots 3 are opened on the top of the device body 1, specifically, five fixing slots 3 are opened on the top of the device body 1; the device body 1 has foot slots 4 on both the front and rear sides of the fixing slot 3; the handle includes two symmetrically arranged connecting arms 5 that are rotatably connected to the left and right sides of the device body 1 and a fixing member 6 that is slidably connected to the two connecting arms 5, the two ends of the fixing member 6 are respectively slidably connected to the two connecting arms 5, and a locking device is connected between the connecting arm 5 and the fixing member 6, and the fixing member 6 is locked to the connecting arm 5 through the locking device; a transverse connecting slot 7 corresponding to the fixing member 6 is also opened on the top of the device body 1, and the transverse connecting slot 7 is communicated with the above-mentioned five fixing slots 3.

[0029] Specifically, in the connection between the connecting arm 5 and the device body 1, there are a straight-line plug-in slot 21 on both sides of the device body 1, and a plug-in block 22 is inserted into the plug-in slot 21. The outer end of the plug-in block 22 is connected to the rotating shaft 23, and the outer end of the rotating shaft 23 is connected to the limit block 24; the connecting arm 5 is rotatably connected to the rotating shaft 23 and is limited between the limit block 24 and the device body 1; the plug-in block 22 is connected to the device body 1 by a connecting bolt 25, and the bottom end of the connecting bolt 25 passes through the limit block 24, the rotating shaft 23 and the plug-in block 22 and the device body 1 threaded connection (reference Figure 5 、 Figure 8 、 Figure 9 as well as Figure 12 Therefore, the utility model adopts a detachable connection for the connecting arm 5. When the connecting arm 5 needs to be disassembled, the connecting bolt 25 is unscrewed, and the plug block 22, the rotating shaft 23 and the limit block 24 can be directly removed, and the connecting arm 5 can also be directly removed from the device body 1.

[0030] When the fixing member 6 is in a locked state, the fixing member 6 is locked in the locked state by locking the fixing member 6.
