A voltage regulator fault detection device

Abstract

This utility model discloses a voltage regulator fault detection device, including a body, a display panel, buttons, an interface, and a carrying structure. In use, the body is fixed to the operator's wrist via a strap and a fixing base. This allows the operator to hold the detection pen with both hands while the body is secured to their wrist for easy carrying and use. Rotating the body drives the fixing rod, which in turn drives the gear. Since the locking head is held in the gear by an elastic element, it engages with the gear after the body is rotated, allowing for easy positioning and adjustment of the body after rotation.

Description

Technical Field

[0001] This utility model relates to the field of voltage regulator technology, specifically a voltage regulator fault detection device. Background Technology

[0002] A voltage regulator is a power regulator, also known as a "thyristor power regulator," "silicon controlled rectifier power regulator," or simply a "power regulator." A "thyristor," also known as a "silicon controlled rectifier" (SCR), is a four-layer, three-terminal semiconductor device. By connecting it between the power supply and the load, and with the corresponding trigger control circuit board, the voltage, current, and power applied to the load can be adjusted. A voltage regulator fault detection device can measure the input / output voltage and resistance of the voltage regulator, thereby detecting the voltage and resistance of the voltage regulator.

[0003] Existing fault detection devices have the following problems:

[0004] Existing fault detection devices require both hands to hold the testing pen when carried out, so the device can only be placed on the ground or other places, which leads to inconvenience in use during the testing process. Utility Model Content

[0005] The purpose of this invention is to provide a voltage regulator fault detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a voltage regulator fault detection device, comprising a body, a display panel, buttons, and an interface, a carrying structure on the back of the body, the carrying structure including a fixed base, an extension rod on the fixed base, a strap connected to the extension rod, and a rotating structure inside the fixed base.

[0007] Preferably, the back of the fixing seat is flat.

[0008] Preferably, the strap is rotatably connected to the extension rod, and the strap is elastic.

[0009] Preferably, the rotating structure includes a fixed rod, which is fixed to the rear end face of the machine body. The fixed rod is rotatably connected to the fixed seat. A gear is provided on the fixed rod. A fixed block is provided inside the fixed seat. An elastic element is installed on the fixed block. A locking head is provided on the elastic element.

[0010] Preferably, the clip head is engaged in the gear by an elastic element, and when the clip head is engaged in the gear by the elastic element, the elastic element is under force.

[0011] Preferably, the fixing base has two fixing blocks inside, and the two fixing blocks have the same structure.

[0012] Preferably, a fixing box is fixed inside the fixing base, the fixing rod passes through the middle of the fixing box, and a pressure member is fixed inside the fixing box.

[0013] Preferably, the pressing element presses against the surface of the fixing rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, the device is secured to the operator's wrist via a strap and a fixing base. This allows the operator to hold the testing pen with both hands while the device is fixed to their wrist for easy carrying and use. Rotating the device moves the fixing rod, which in turn drives the gear. Since the locking head is held in the gear by an elastic element, it will lock into the gear after the device is rotated. This allows for easy positioning and adjustment of the device after rotation, ensuring timely positioning after rotation. Attached Figure Description

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a voltage regulator fault detection device, including a body 1, a display panel 2, buttons 3, an interface 4, and a carrying structure 5 on the back of the body 1.

[0024] Specifically, the test pen is connected to interface 4 to connect the test pen to the body 1. The test pen comes into contact with the detection part of the voltage regulator to measure the voltage or resistance, thereby testing the voltage regulator.

[0025] Please see Figure 3 , Figure 4 and Figure 5 This utility model provides a voltage regulator fault detection device. The carrying structure 5 includes a fixed seat 51. The fixed seat 51 is provided on the back of the body 1. The back of the fixed seat 51 is flat. An extension rod 52 is integrally formed on the fixed seat 51. A strap 53 is rotatably connected to the extension rod 52. The strap 53 is elastic. A rotating structure 54 is provided inside the fixed seat 51.

[0026] Specifically, during use, the operator can insert their hand between the strap 53 and the fixing seat 51. The fixing seat 51 rests against the back of the wrist. When the hand is inserted, the strap 53 will extend under force, and under the action of elasticity, the fixing seat 51 will be fixed on the operator's wrist. Since the back of the fixing seat 51 is flat, it is not easy for the fixing seat 51 to rotate or tilt when it is fixed on the wrist. By fixing the machine body 1 to the operator's wrist through the strap 53 and the fixing seat 51, the machine body 1 can be fixed on the operator's hand. Therefore, when the operator holds the testing pen with both hands, the machine body can be fixed on the wrist for easy carrying and convenient use.

[0027] Please see Figure 4 The rotating structure 54 includes a fixed rod 541. The fixed rod 541 is fixed to the rear end face of the machine body 1. The fixed rod 541 is rotatably connected to the fixed seat 51. A gear 542 is fixed on the fixed rod 541. Two fixed blocks 543 are fixed inside the fixed seat 51. An elastic element 544 is installed on the fixed block 543. A locking head 545 is provided on the elastic element 544. The locking head 545 is engaged in the gear 542 through the elastic element 544. When the locking head 545 is engaged in the gear 542 through the elastic element 544, the elastic element 544 is under force, which has a more stable locking effect.

[0028] Specifically, when the direction of the machine body 1 needs to be adjusted, the operator can rotate the machine body 1 to drive the fixing rod 541, which in turn drives the gear 542 to rotate. Since the clamp 545 is clamped in the gear 542 through the elastic element 544, after rotating the machine body 1, the clamp 545 will be clamped in the gear 542, so that the machine body 1 can be fixed after rotating and adjusting its position, which facilitates the rotation and adjustment of the machine body 1 and ensures timely positioning after rotation.

[0029] Please see Figure 5 The fixing base 51 has a fixing box 551 inside, the fixing rod 541 passes through the middle of the fixing box 551, and the fixing box 551 has a pressing member 552 inside, which presses against the surface of the fixing rod 541.

[0030] Specifically, since the pressure member 552 presses against the surface of the fixing rod 541, the fixing rod 541 is not easy to rotate, thus improving the stability of the rotating structure 54 after it is locked in place.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
