Description

Technical Field

[0001] This utility model relates to the field of voltage testing pen technology, specifically an inductive voltage testing pen. Background Technology

[0002] A digital display voltage tester, also known as an inductive voltage tester, can not only test whether an object is charged, but also display the approximate voltage range. In addition, some digital display voltage testers can detect the location of a break in an insulated wire. The buttons on the voltage tester are made of metal. When measuring, the hand should press and hold the button to form a current loop. Usually, the button for direct measurement is farther away from the display screen, while the button for inductive measurement is closer to the display screen.

[0003] The prior art, application number 202222987371.6, includes a test pen body with a detection probe fixedly installed at the front end and an anti-dislodgement device on one side. This anti-dislodgement device prevents the user's finger from slipping out of the elastic rubber sleeve when using the pen in confined spaces. The elastic sleeve automatically contracts and covers the finger under its elastic force, thus preventing the pen from falling out and becoming difficult to retrieve. The patent also includes an adjustment slider and an adjustment groove, allowing the elastic sleeve to slide and adjust its position on the surface of the pen body. This allows the user to easily assemble and disassemble the elastic sleeve when holding the pen in different positions, making its use flexible and convenient. The patent title is: "An Inductive Test Pen."

[0004] However, after the slider moves to the target position in the groove, it is prone to accidental displacement due to external force or vibration because it is not equipped with a locking mechanism, which affects the detection stability. In addition, the design of the anti-dislodgement mechanism using an elastic rubber sleeve to fix the user's finger has comfort issues. The rubber sleeve may compress blood vessels due to excessive tightening force. Long-term use will lead to poor blood circulation in the fingers, causing numbness or even skin marks, reducing the comfort of operation. Therefore, we have proposed an inductive voltage tester. Utility Model Content

[0005] The purpose of this utility model is to provide an inductive voltage tester to solve the problems mentioned in the background art, such as the inability of the slider to move to the target position in the groove due to the lack of a locking mechanism, which can easily cause accidental displacement due to external force or vibration, affecting the detection stability; the use of elastic rubber sleeves to fix the user's fingers has comfort issues; and the rubber sleeves may compress blood vessels due to excessive tightening force.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inductive voltage tester, comprising a voltage tester body and a limiting chamber, wherein the limiting chamber is fixedly connected to one side of the voltage tester body, and an anti-slip strip is adhered to one side of the voltage tester body, and the anti-slip strips are arranged sequentially, a detection button is provided on the top of the voltage tester body, an inductive measurement button is provided on the top of the voltage tester body, and a digital display screen is provided on the top of the voltage tester body, a movable chamber is slidably connected to one side of the limiting chamber, and a transmission chamber is fixedly connected to one side of the movable chamber, wherein two gear driven screws are rotatably connected to the inner wall of the movable chamber, one end of the gear driven screw penetrates through the movable chamber and extends to the outside of the movable chamber, and a threaded sleeve is screwed to the outside of the gear driven screw.

[0007] As a further description of the above technical solution:

[0008] One end of the threaded sleeve is fixedly connected to a pressing plate, and the outer side of the pressing plate abuts against the limiting chamber.

[0009] As a further description of the above technical solution:

[0010] A telescopic limiting rod is fixedly connected to one side of the extrusion plate, and the telescopic limiting rod is fixedly connected to the movable chamber. A gear transmission rod is rotatably connected to the inner wall of the transmission chamber.

[0011] As a further description of the above technical solution:

[0012] One end of the gear transmission rod passes through the transmission chamber and extends into the inner cavity of the movable chamber, and one end of the gear transmission rod is meshed with the gear driven screw. A gear drive rod is rotatably connected to one side of the transmission chamber.

[0013] As a further description of the above technical solution:

[0014] One end of the gear drive rod passes through the transmission chamber and extends into the inner cavity of the transmission chamber, and one end of the gear drive rod is meshed with the gear transmission rod.

[0015] As a further description of the above technical solution:

[0016] One side of the mobile compartment is fixedly connected to an elastic connecting column, and one end of the elastic connecting column is fixedly connected to an installation compartment. The inner wall of the installation compartment is rotatably connected to a bidirectional screw.

[0017] As a further description of the above technical solution:

[0018] One end of the bidirectional screw passes through the mounting chamber and extends to the outside of the mounting chamber. Two V-shaped clamping blocks are screwed to the outside of the bidirectional screw, and an anti-slip pad is adhered to one side of each V-shaped clamping block.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This inductive voltage tester has a limiting chamber fixed to one side of the tester body. The movable chamber can slide along the limiting chamber to adapt to different usage needs. During adjustment, the user rotates the gear drive rod, which drives the gear transmission rod to rotate, thereby driving the two gear driven screws to rotate synchronously. Since the gear driven screws are screwed to the threaded sleeve, the rotational motion is converted into linear motion, causing the threaded sleeve to push the extrusion plate against the inner wall of the limiting chamber. At the same time, the telescopic limiting rod ensures that the extrusion plate moves in a straight line and avoids deflection. Through this mechanism, the position of the movable chamber can be precisely adjusted and firmly locked to prevent displacement during use.

[0021] 2. This inductive voltage tester has a movable compartment connected to a mounting compartment via a flexible connecting post. The mounting compartment contains a bidirectional screw with two V-shaped clamping blocks screwed to its ends. When the bidirectional screw is rotated, the two V-shaped clamping blocks move synchronously in opposite directions to accommodate different user finger sizes. Anti-slip pads on the inner side of the V-shaped clamping blocks enhance friction and prevent accidental slippage of the voltage tester. The flexible connecting post provides cushioning to avoid discomfort from rigid clamping while ensuring moderate clamping force that does not affect blood circulation in the fingers.
