It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0021] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0022] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides a diode testing device, comprising: a bottom plate 1, a fixing frame 2 is fixedly connected to the top of the bottom plate 1, a motor 3 is fixedly connected to the center of the bottom of the fixing frame 2, the output end of the motor 3 rotatably penetrates through the bottom of the fixing frame 2, the output end of the motor 3 is fixedly connected to a rotating rod 4, and a testing component 8 is fixedly connected to the top of the rotating rod 4; the testing component 8, the testing component 8 includes a turntable 801, the turntable 801 is fixedly connected to the top of the rotating rod 4, mounting blocks 802 are respectively fixedly connected to the outer surface of the turntable 801, magnets 803 are symmetrically arranged between the inner surfaces of the two mounting blocks 802, placing blocks 804 are respectively arranged between the opposite outer surfaces of the plurality of magnets 803, fixing rods 808 are symmetrically and fixedly connected to the bottoms of the two mounting blocks 802, springs 809 are respectively sleeved on the outer surfaces of the plurality of fixing rods 808, the plurality of fixing rods 808 are divided into two groups, push blocks 806 are slidably connected to the outer surfaces of the two groups of fixing rods 808, touch rods 807 are arranged at the bottoms of the two push blocks 806, wires 805 are arranged on the outer surfaces of the two placing blocks 804, the outer surfaces of the two wires 805 away from the two placing blocks 804 are arranged on the outer surfaces of the two push blocks 806, the wires 805 and the touch rods 807 are in a matching setting, the outer surface of the placing block 804 fits with the inner surface of the mounting block 802, the placing block 804 and the magnet 803 are in a matching setting, the spring 809 is located between the bottom of the mounting block 802 and the top of the push block 806, the spring 809 and the push block 806 are in a matching setting, contact blocks 5 are symmetrically arranged near the edge of the inner bottom of the fixing frame 2, the contact blocks 5 and the touch rods 807 are in a matching setting, connecting rods 6 are arranged at the bottoms of the two contact blocks 5, and connecting blocks 7 are arranged at the bottoms of the two connecting rods 6.
[0023] The effect achieved by the entire Embodiment 1 is that during the diode test, first, turn the multimeter gear provided at the top of the base plate 1 to the diode test gear. Then, insert the black and red test leads of the multimeter into the top holes of the two connecting blocks 7 respectively. Both the two connecting blocks 7 and the connecting rod 6 are made of metal, enabling the two test leads of the multimeter to be electrically connected to the two contact blocks 5 made of metal respectively. Place the two ends of the diode to be tested steadily inside the placement blocks 804. The two placement blocks 804 are made of metal and are magnetized under the influence of the symmetrically arranged magnets 803 on the inner surface of the mounting block 802. The inner sides of the two placement blocks 804 can tightly adsorb the two end pins of the diode and are electrically connected through the two wires 805 and the two contact rods 807 respectively. The two contact rods 807 are arranged at the bottoms of the two pushing blocks 806. Under the action of the multiple springs 809, the two pushing blocks 806 slide down along the corresponding two fixed rods 808, driving the two contact rods 807 to always abut against the tops of the two contact blocks 5. Both the two contact rods 807 are made of metal. When their bottoms abut against the tops of the contact blocks 5, the two test leads of the multimeter will be electrically connected to the two ends of the diode to be tested. At this time, the multimeter tests the two ends of the diode by applying current, and the test value will be directly displayed on the multimeter. Then, start the motor 3. The output end of the motor 3 drives the turntable 801 to rotate horizontally by 180 degrees through the rotating rod 4. At this time, the bottoms of the two contact rods 807 will respectively slide along the tops of the two contact blocks 5 until the two contact rods 807 swap positions with each other. At this time, the multimeter verifies whether it is unidirectional conduction again by applying current. During the diode test process, the operator only needs to observe the value displayed on the multimeter throughout the process, without using the two test leads of the multimeter to continuously contact the two ends of the diode and reverse the connection of the two test leads according to the test needs to test the two ends of the diode, reducing the operator's work intensity.
[0024] Embodiment 2, as Figures 1 - 4 shown, an inner ring block 9 is fixedly connected to the inner bottom of the fixing frame 2. The inner ring block 9 and the contact rod 807 are provided in a matching manner. The outer surfaces of the two connecting rods 6 both fixedly penetrate through the inner bottom of the fixing frame 2, and the two contact blocks 5 are both located outside the inner ring block 9.
[0025] The effect achieved by the entire Embodiment 2 is that during use, by fixedly arranging the inner ring block 9 at the inner bottom of the fixing frame 2 near the two contact blocks 5, the inner ring block 9 cooperates with the top edge of the fixing frame 2 to play a limiting role on the two contact rods 807, enabling them to only slide along the tops of the two contact blocks 5, preventing the two contact rods 807 from shifting during rotation and affecting the diode test, with high practicability.
[0026] Working principle: When testing a diode, insert the black and red test leads of the multimeter into the top holes of the two connection blocks 7 respectively, so that the two test leads are electrically connected to the two contact blocks 5 made of metal through the two contact blocks 5 made of metal and the two connecting rods 6 respectively. The two lead pins at both ends of the diode to be tested are respectively placed inside the two placement blocks 804. The two placement blocks 804 are made of metal and are magnetized under the magnetic action of multiple magnets 803, so as to tightly adsorb the two metal lead pins of the diode placed inside, and are electrically connected through the two wires 805 and the two contact rods 807 respectively. When the bottoms of the two contact rods 807 respectively abut against the tops of the two contact blocks 5, the two lead pins at both ends of the diode are electrically connected to the black and red test leads of the multimeter respectively. At this time, the multimeter tests both ends of the diode by applying current, and the test values will be directly displayed on the multimeter. Then start the motor 3. The output end of the motor 3 drives the turntable 801 to rotate horizontally by 180 degrees through the rotating rod 4. At this time, under the combined action of the two pushing blocks 806 and the multiple springs 809, the bottoms of the two contact rods 807 will respectively slide on the tops of the two contact blocks 5 until the two contact rods 807 swap positions with each other. At this time, the multimeter verifies whether it is unidirectional conduction again by applying current. During the testing process of the diode, the operator only needs to observe the values displayed on the multimeter throughout the process, without using the two test leads of the multimeter to continuously contact both ends of the diode, and reverse the connection of the two test leads to the two ends of the diode for testing according to the test requirements, reducing the labor intensity of the operator.
[0027] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
