Description

Technical Field

[0001] The present application belongs to the technical field of electrical parameter acquisition, and specifically relates to an electrical parameter measuring device. Background Art

[0002] Electrical parameters include voltage, current, resistance, and so on. The devices used for measurement are also placed on different device components. Existing electrical parameter measurement devices generally use wired communication. The device used for measurement contacts the component to be measured, and after contact, the test results are transmitted to the outside through the wire.

[0003] For example, publication number CN207686712U discloses an oil well electrical parameter measuring device, which includes: a data acquisition unit, used to collect electrical parameters of oilfield production equipment according to an acquisition instruction sent by a remote terminal; a wireless communication unit, used to receive the acquisition instruction sent by the remote terminal and send the electrical parameters to the remote terminal; a relay output unit, used to send a shutdown control signal to the oilfield production equipment when the electrical parameters are abnormal; a switch input unit, used to receive an operating status signal sent by the oilfield production equipment; and a power supply, used to power the data acquisition unit, the wireless communication unit, the relay output unit, and the switch input unit.

[0004] However, in actual use, it was found that the existing electrical parameter measuring devices are generally more complex in structure on large devices and are designed and manufactured according to the large devices. However, on small devices such as multimeters, they are generally lacking in design and still follow the traditional method in structure. For example, direct contact with a stylus is used for detection. However, since the parts to be detected, such as the curved surfaces of pipelines, are unstable when the hand is held in contact, it is easy to cause disconnection or even accidental touch by the operator when the detection takes a little longer, which poses certain safety hazards. Therefore, it is necessary to add appropriate components when performing electrical parameter measurement so that the stylus can stably contact the object to be measured and save the operator's manpower to avoid accidental touch, so as to protect the operator. Utility Model Content

[0005] The purpose of the present application is to provide an electrical parameter measuring device in order to solve the above-mentioned problem of ensuring stable contact of a stylus pen with a curved surface during measurement.

[0006] The technical solution adopted in this application is as follows: an electrical parameter measuring device, wherein a plug-in ring is inserted into the side surface of the touch pen, and a ring fastening bolt is provided on the side surface of the plug-in ring, and a plurality of rotating plug shafts are rotatably inserted into the side surface of the plug-in ring, and a lap frame rod is inserted into the side surface of the rotating plug shaft relative to one end of the plug-in ring, and a lap joint connecting shaft is inserted into the side surface of the lap frame rod, and a lap joint connecting shaft is rotatably inserted into the side surface of one end of the lap frame rod, and a lap joint connecting block is rotatably connected to the side surface of the lap joint connecting block, and a lap joint is fixedly connected to the side surface of the lap joint connecting block, and a lap joint fastening bolt is provided on the side surface of the lap joint connecting block, and the metal end of the touch pen is fixedly inserted into the side surface of the touch pen.

[0007] By adopting the above technical solution, the operator uses the metal end of the stylus pen to contact the component under test. Before contact is made, the operator uses the rotating plug shaft, lap frame rod, lap joint connecting shaft, lap joint connecting block, and lap joint connected to the plug collar as auxiliary components to place them on the component under test. After achieving relatively stable contact, the operator rotates the stylus pen using the rotating plug shaft so that the metal end of the stylus pen rests easily on the component under test.

[0009] The connection between the stylus pen and the plug-in sleeve is fastened by the sleeve fastening bolt. Since the plug-in sleeve itself can slide on the stylus pen, the distance between them can be adjusted according to the actual measurement situation. As an auxiliary device, it can also be removed to replace it with a completely handheld measurement, adding a lot of flexibility.

[0010] The rotating plug shaft is used as one of the connecting parts, and its rotational property enables relative rotation between the touch pen and the overlapping frame rod. The overlapping frame rod is a frame part, which is used to connect the overlapping joint connection block and the overlapping joint.

[0011] The lap joint connection block is used to connect the lap joints, and the lap joint uses its curved and bent structure to contact curved surfaces, such as pipe or wire surfaces. The lap joint connection shaft is used to connect the lap frame rod and the lap joint connection block, and its rotational performance allows the lap joint to better adjust the contact angle. The lap joint fastening bolts are used to tighten the rotation angle of the lap joint connection block.

[0012] The above components are all made of insulating plastic materials. Through the above structure, when the operator is measuring electrical parameters, there can be certain auxiliary contact devices on the surface of the curved component to be measured. The operator does not need to maintain continuous contact with his hands. The auxiliary contact devices can save time and effort, and the operation is more flexible and convenient.

[0013] In a preferred embodiment, a protective ring is fixedly connected to the side surface of the stylus pen, and a wire is plugged into the side surface of one end of the stylus pen opposite to the metal end of the stylus pen.

[0014] By adopting the above technical solution, the stylus pen used for measurement is connected to the main body of the measuring device using a wire, and the measurement signal is transmitted. The protective ring is used as a protective component to prevent the operator from touching the metal end of the front stylus pen with his bare hands, which may cause danger.

[0015] In a preferred embodiment, a measuring device is plugged into a side surface of one end of the wire facing the stylus pen, and a display screen is provided on the side surface of the measuring device.

[0016] By adopting the above technical solution, the measuring device is used as the measuring device body, and the display screen thereon is used as a display component to display the magnitude of the measured electrical parameter for easy reading.

[0017] In a preferred embodiment, a mode switching button is provided on a side surface of the measuring device, and a switch button is provided on a side surface of the measuring device.

[0018] By adopting the above technical solution, the mode switching button is used as a measurement mode switching button component to measure multiple different electrical parameters such as current and voltage, while the switch button is used as the switch button of the entire device to control the operation of the entire device.

[0019] In a preferred embodiment, the side surface of the measuring device is provided with an adhesive backing plate.

[0020] By adopting the above technical solution, the adhesive backboard is used as the backboard component for pasting, and a flow chart of pasting is provided on it.

[0021] In a preferred embodiment, a gear shift adjustment knob is provided on a side surface of the measuring device.

[0022] By adopting the above technical solution, the gear shift adjustment knob is used as a setting component for shifting gears to switch between direct current and alternating current.

[0025] In a preferred embodiment, a sound hole is provided on a side surface of the measuring device.

[0026] By adopting the above technical solution, the sound hole is used as a sound hole for prompting. When a disconnection occurs, a buzzing sound will be emitted from it.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0028] In this application, the stylus serves as the main component of the contact device used for testing, acting as an intermediary to connect multiple components. The metal end of the stylus directly contacts the component under test. The stylus itself is made of insulating material.

[0029] The connection between the stylus pen and the plug-in sleeve is fastened by the sleeve fastening bolt.
