Description

Technical Field

[0001] The utility model relates to the technical field of resistance testers, in particular to a hand-cranked insulation resistance tester with protective measures. Background Art

[0002] A hand-cranked insulation resistance tester with protective measures, whose design includes protective measures, dust and water resistance and speed display functions, which are realized through technologies such as insulating shell, rubber gasket and speed sensor. These designs ensure user safety, ensure reliable operation of the equipment in harsh environments, and provide accurate hand-cranked speed monitoring. An existing electrical equipment insulation resistance tester structure (publication number: CN208984715U) has the following disadvantages and needs further improvement.

[0003] 1. Traditional equipment lacks designs such as insulating shells. When accidental electric shock or other safety accidents occur, the power supply cannot be cut off in time, increasing the risk of injury to users. Lacking protective designs such as insulating shells, traditional equipment is easily affected by external environmental factors such as dust and moisture, resulting in equipment damage or unstable operation. Lacking a protection mechanism to automatically cut off the power supply, the use of traditional equipment requires more caution and care, which is relatively inconvenient to operate and prone to operational errors. Therefore, there is an urgent need for a resistance tester with protective measures.

[0004] 2. Traditional equipment does not have a dustproof and waterproof design, and is easily corroded by harsh environmental factors such as dust and moisture, causing damage or short circuit of internal components of the equipment, affecting the normal operation of the equipment. The lack of dustproof and waterproof design will reduce the reliability of traditional equipment in harsh environments, making it prone to failures, affecting the accuracy and stability of test results. Due to the lack of dustproof and waterproof design, traditional equipment is more susceptible to environmental erosion, resulting in the need for regular maintenance and upkeep, increasing maintenance costs and workload. Therefore, there is an urgent need for a resistance tester with a dustproof and waterproof design.

[0005] 3. Due to the lack of speed display function, traditional equipment cannot monitor the hand-cranking speed in real time when using traditional equipment. It is difficult for operators to grasp whether the hand-cranking speed is appropriate, which can easily affect the accuracy and reliability of the test. The lack of speed display technology will cause the operator to be unable to accurately control the hand-cranking speed, which may cause speed fluctuations or instability during the test, thereby affecting the reliability of the test results. Without the speed display function, the operator needs to rely on experience and feeling to control the hand-cranking speed, which increases the difficulty and technical requirements of the operation and is prone to operating errors. Therefore, a resistance tester with speed display is urgently needed. Utility Model Content

[0006] The main purpose of the utility model is to provide a hand-cranked insulation resistance tester with protective measures, which can effectively solve the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: there is a hand-cranked insulation resistance tester with protective measures, a pull rod is installed above the main body, a control rocker is installed on one side of the main body, a rubber gasket is installed on one side of the main body, an indicator light is installed above the main body, a display is installed above the main body, a tachometer is installed above the main body, an insulating shell is installed above the main body, a speed sensor is installed above the main body, an input device is installed above the main body, and an output device is installed above the main body.

[0008] Preferably, the exterior of the main body adopts a rounded corner design.

[0009] Preferably, the control rocker is rotatable.

[0010] Preferably, the insulating shell is fixed above the main body by a hinge.

[0011] Preferably, the input device and the output device are externally designed to increase friction.

[0012] Preferably, the pull rod has a round hole inside for fixing.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model can effectively isolate the internal circuits and components by adding an insulating shell, reducing the risk of accidental electric shock. Once an accidental electric shock or other safety accident occurs, the insulating shell can play a certain protective role and reduce the risk of injury to the user. The insulating shell can effectively block the erosion of external environmental factors such as dust and moisture, thereby protecting the equipment from damage or unstable operation and extending the service life of the equipment. Resistance testers with an insulating shell design are usually equipped with corresponding safety switches and automatic power-off protection mechanisms, which can reduce the need for users to be particularly cautious and careful during operation, improve the convenience and safety of operation, and reduce the possibility of operational errors.

[0015] 2. The utility model can effectively seal the device casing by adding a rubber gasket to prevent dust, moisture and other harsh environmental factors from corroding the inside of the device. This can protect the internal components from damage or short circuits, improve the reliability of the device in harsh environments, and reduce the possibility of equipment failure, thereby ensuring the accuracy and stability of the test results. Since the rubber gasket can effectively prevent environmental erosion, the maintenance cost and workload caused by damage to the equipment can be reduced. The equipment no longer requires regular maintenance and servicing, thereby reducing maintenance costs and workload and improving the efficiency of equipment use. The dustproof and waterproof design of the rubber gasket can extend the service life of the equipment, reduce damage to the equipment caused by harsh environments, and improve the durability and stability of the equipment.

[0016] 3. The utility model can monitor the hand-cranking speed in real time by adding a speed sensor, a tachometer and an indicator light, and display it through the tachometer, so that the operator can clearly understand the current hand-cranking speed. It can help the operator to accurately control the hand-cranking speed and avoid speed fluctuations or instability, thereby improving the reliability and accuracy of the test process. Through the speed display function, the operator does not need to rely solely on experience and feeling to control the hand-cranking speed, but can directly adjust it according to the indication of the tachometer. It can reduce the difficulty and technical requirements of the operation, reduce the possibility of operating errors, and improve the accuracy of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In this embodiment, first, when the user is ready to start the test, the input device needs to be connected to the main body to input the test parameters and instructions. At the same time, the control joystick can be used to start the device and set the test conditions. Then, the user can operate the control joystick through the pull rod to start the hand-cranking operation. The speed sensor monitors the hand-cranking speed in real time and transmits the data to the tachometer and the display. The tachometer will display the current hand-cranking speed based on the data of the sensor, and the indicator light may be used to indicate the operating status of the device or remind the user of relevant information. During the hand-cranking process, the rubber gasket plays a sealing role to protect the internal components from the erosion of the external environment. This helps to ensure the stability and reliability of the device in harsh environments and extend the service life of the device. In addition, the design of the insulating shell can effectively isolate the internal circuits and components and reduce the risk of accidental electric shock. At the same time, the insulating shell can also block the erosion of external factors such as dust and moisture, protect the device from damage, and improve the stability and safety of the device. Finally, after the test is completed, the output device is used to output the test results or data for the user to view and record.
