Description

Technical Field

[0001] The present application relates to an electronic measuring instrument, and in particular to a low-cost simple testing device. Background Art

[0002] In the field of electronic measuring instruments, performance testing of power supply products is a critical step in ensuring product quality and reliability. Currently, power supply product testing mostly relies on traditional, large-scale test equipment. This equipment is typically bulky and complex, requiring dedicated testing sites and specialized operators. Furthermore, existing test equipment is often based on fixed test platforms, making it difficult to conduct on-site testing of power supply products. This often requires transporting finished power supply products to a specific testing area, resulting in a cumbersome and inefficient testing process.

[0003] The above-mentioned related technologies generally have the problems of being expensive and too heavy to be carried and moved, which leads to reduced work efficiency, increased maintenance costs and procurement costs, and higher budget requirements for the product production line itself. Therefore, a low-cost and simple testing device is urgently needed. Summary of the Invention

[0008] Preferably, a hidden groove is provided at the bottom of the base plate, the hidden groove is matched with the support ring, and the bottom of the cleaning brush is matched with the bottom of the hidden groove.

[0009] On the second aspect, a low-cost and simple testing device provided in the present application adopts the following technical solution: the extension mechanism includes a motor, the right side of the motor is fixedly connected to the left side of the base plate, the output shaft of the motor is fixedly connected to a bidirectional threaded rod, one end of the bidirectional threaded rod is threadedly connected to a first moving block, and the other end of the bidirectional threaded rod is threadedly connected to a second moving block, and the outer surfaces of the first moving block and the second moving block are fixedly connected to a mounting plate.

[0010] Preferably, two long grooves are provided at the bottom of the base plate, both of which are adapted to the bidirectional threaded rod, and the left side of the bidirectional threaded rod movably passes through the interior of the base plate and extends to the left side of the base plate.

[0011] Preferably, the cooling mechanism includes a rubber ring, the outer side of the rubber ring is fixedly connected to the inside of the mounting plate, a slot is provided inside the rubber ring, a plug-in plate is inserted into the slot, a fan is fixedly connected to the inside of the plug-in plate, two fans are provided, and both fans have air outlets on the side close to the test device body.

[0012] Preferably, the bottom of the mounting plate is fixedly connected to a protective shell, the bottom of the inner wall of the protective shell is fixedly connected to a pressure sensor, the bottom of the mounting plate is fixedly connected to a cylinder, the output end of the cylinder is fixedly connected to a fixed plate, a fixing slot is provided on the left side of the plug-in plate, the slot is adapted to the fixed plate, and the pressure sensor is electrically connected to the cylinder.

[0013] Preferably, a button is fixedly connected to the front of the protective shell, and the button is electrically connected to the pressure sensor. The side of the fixing plate close to the test device body movably passes through the outside of the protective shell and extends to the inside of the protective shell.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. The test device body is the core part of the entire test device and undertakes the main test function. The bottom of the test device is fixedly connected with a rotating wheel, which makes the whole device mobile and convenient for testing in different positions. The bottom plate is an extension plate for installing other structures. The fixing ring is fixedly connected to the inside of the bottom plate as the fixing point of the first electric stretching rod. The first electric stretching rod has a telescopic function and can adjust the length as needed. The support plate is set at the bottom of the first electric stretching rod. When the stretching rod is extended, the support plate will contact the ground, thereby increasing the stability of the device and adjusting the height of the equipment to adapt to power supply tests at different heights while preventing it from During the test, the second electric stretching rod acts as a supporting and retracting device, pressing the support ring downwards through the spring rod, so that the cleaning brush cleans the ground. When the device needs to be fixed after moving for a period of time, the cleaning brush cleans the moving path and protects the internal support plate, ensuring that the support plate will not be blocked by impurities or small objects such as parts when it is pressed down, causing the support plate to be unable to be fully pressed down to produce a fixing effect. The second electric stretching rod acts as a support, and the spring rod acts as a secondary source of downward force, which can ensure the cleaning of the cleaning brush according to different terrains. The hidden groove is the same size as the support ring. When the device is ready to be fixed, the second electric stretching rod is retracted. The spring rod is allowed to carry the support ring and the cleaning brush at the bottom upwards and retracted into the hidden groove to avoid affecting the use of other structures. This fixing mechanism can more conveniently fix the test device body and quickly change its position when needed. It can also adjust its height to adapt to power supplies to be tested at different heights, avoiding the problems of cumbersome and inefficient test processes. 2. The extension mechanism serves as the main connecting mechanism between the cooling mechanism and the fixing mechanism, and is responsible for realizing the extension or contraction function of the device to adapt to the needs of different test scenarios. The motor rotates the bidirectional threaded rod, so that the first movable block and the second movable block move in opposite directions respectively, and the mounting plate is extended outward. The device itself is first supported to a certain height by the fixing mechanism, or the device is pulled to a certain height by a manual machine, and then the chassis size of the device is expanded by extending the mounting plates on both sides, so that it can be supported on two support frames, tables or shelves, and its position and height can be adjusted more flexibly. The long groove is used to accommodate the bidirectional threaded rod and serves as protection for the internal bidirectional threaded rod and the first movable block and the second movable block to prevent them from being affected by the external environment. The extension mechanism can fix the position of the device more flexibly, and the device itself is no longer limited to height issues and can be freely supported on other objects; 3. The rubber ring is installed inside the mounting plate, and the plug-in board is installed through the slot. The slot inside the rubber ring can increase the resistance to insertion and removal, and can also reduce the vibration from the plug-in board through the toughness of the rubber ring itself to prevent it from shaking. The fan faces the test device body to cool the test device body. The structure installed on the plug-in board can also be other equipment, such as a monitoring device for remote monitoring of the test status. The protective shell also serves as a limiting structure to allow the bottom of the plug-in board to fit and support it. The pressure sensor is used to confirm whether there is a plug-in board inserted in the protective shell. When the plug-in board falls on the pressure sensor and generates pressure, it triggers the pressure sensor and sends a signal to the cylinder. , so that it is opened and the fixing plate is pushed into the fixing groove of the plug-in plate to automatically complete the fixation. The button is used as an active switch. By pressing the button, a signal is generated to the pressure sensor to close it. When the pressure sensor is closed, the cylinder no longer receives the signal and automatically retracts the fixing plate to make it withdrawn from the plug-in plate. At this time, the plug-in plate can be freely withdrawn to repair the structure on the plug-in plate or replace the plug-in plate. The cooling mechanism can cool the equipment and the plug-in plate can be replaced freely, so that the cooling mechanism itself can also act on other structural uses, which increases flexibility. The automatic fixing and convenient unfastening of the fixed structure also reduces the cost of manual fixing and disassembly, making it more cost-effective. BRIEF DESCRIPTION OF THE DRAWINGS

The first electric stretching rod 104 has a telescopic function and can adjust its length as needed. The support plate 105 is arranged at the bottom of the first electric stretching rod 104. When the stretching rod is extended, the support plate 105 will contact the ground, thereby increasing the stability of the device, adjusting the height of the equipment, adapting to power supply tests of different heights and preventing it from moving during the test.
