Description

Technical Field

[0001] This utility model relates to the field of multimeter devices, specifically a handheld multimeter. Background Technology

[0002] A multimeter, also known as a multi-purpose meter, is an indispensable measuring instrument in the power electronics and other industries. It is generally used to measure voltage, current and resistance. However, existing multimeters do not provide effective holding points during use, making them inconvenient to handle and move later.

[0003] According to patent document CN219590402U, a handheld multimeter device is disclosed, which includes a multimeter and a dustproof barrier at the multimeter's jack. A locking device is fixedly installed on the multimeter, and test leads are engaged with the locking device. Preferably, the dustproof barrier includes an adhesive patch, a first magnetic piece, and a second magnetic piece. One side of the adhesive patch is fixedly connected to the multimeter, and the adhesive patch covers the multimeter's jack. The second magnetic piece is embedded in the multimeter, and the first magnetic piece is embedded in the adhesive patch and attracted to the second magnetic piece. In use, the adhesive patch covers the multimeter's jack, thus preventing dust and increasing the accuracy of subsequent insertion and connection testing. However, while this solution achieves dust prevention, it cannot limit and fix the adjusted resistance value during use. Impacts can easily cause the knob to loosen, potentially damaging the multimeter and causing inconvenience during use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a handheld multimeter to solve the problems mentioned in the background. This utility model has a novel structure. In use, the limiting post is installed inside the limiting hole. The limiting post and the limiting hole cooperate to limit and fix the fixed block and the rotating seat. After the rotating seat is limited and fixed, the adjusted value is positioned to avoid damage during measurement caused by collision or movement later.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a handheld multimeter, comprising a multimeter body, the multimeter body including a fixed base, a display mechanism fixedly mounted on the fixed base, a rotating base rotatably mounted on the fixed base, a fixing block fixedly mounted on the rotating base, a fixing frame mounted on the side of the rotating base, the fixing frame fixedly mounted on the fixed base, a movable base rotatably mounted on one side of the fixed base, the movable base being mounted on the fixed base via a rotating column, and the movable base having fixing holes and fixing grooves respectively.

[0006] Furthermore, a movable plate is movably installed inside the fixing groove, and a handle is provided on the movable plate. A detection pen is movably installed inside the fixing hole.

[0007] Furthermore, a connecting groove is provided between the fixing groove and the fixing hole, and a connecting plate is movably installed inside the connecting groove, with one end of the connecting plate fixed to the movable plate.

[0008] Furthermore, the other end of the connecting plate is movable and cooperates with the detection pen, and a reset mechanism is fixedly installed inside the connecting groove, with one end of the reset mechanism fixedly installed on the connecting plate.

[0012] 1. In this handheld multimeter, the limiting post is installed inside the limiting hole during use. The limiting post and the limiting hole cooperate to limit and fix the fixed block and the rotating seat. After the rotating seat is limited and fixed, the adjusted value is positioned to avoid damage during measurement caused by collision or movement later.

[0013] 2. This handheld multimeter features a rotating movable base that opens the wiring hole during use and seals the wiring hole when not in use to prevent dust from entering. Additionally, the movement of the movable plate allows the test pen to be removed. The movable base rotates the movable plate, which then moves, exposing the opening on the movable plate from the side of the fixed base to form a handle, facilitating the overall handling and movement of the device.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a handheld multimeter, including a multimeter body, the multimeter body including a fixed base 1, a display mechanism 2 fixedly installed on the fixed base 1, a rotating base 4 rotatably installed on the fixed base 1, a fixed block 16 fixedly installed on the rotating base 4, a fixed frame 3 installed on the side of the rotating base 4, the fixed frame 3 fixedly installed on the fixed base 1, a movable base 5 rotatably installed on one side of the fixed base 1, the movable base 5 being installed on the fixed base 1 via a rotating column 15, the movable base 5 having a fixed hole 9 and a fixed groove 10 respectively, a movable plate 7 movably installed inside the fixed groove 10, a handle 8 being provided on the movable plate 7, and a test pen 6 movably installed inside the fixed hole 9. The test pen 6 is stored inside the fixed hole 9 when not in use, facilitating the carrying and movement of the entire device and preventing the test pen 6 from being lost during transport.

[0022] In this embodiment, a connecting groove 11 is formed between the fixing groove 10 and the fixing hole 9. A connecting plate 12 is movably installed inside the connecting groove 11. One end of the connecting plate 12 is fixed to the movable plate 7, and the other end of the connecting plate 12 movably cooperates with the detection pen 6. A reset mechanism 13 is fixedly installed inside the connecting groove 11. One end of the reset mechanism 13 is fixedly installed on the connecting plate 12. A wiring hole 14 is formed on one side of the fixing base 1, and the wiring hole 14 is connected to the wire of the detection pen 6. A sliding groove is formed on the fixing block 16. 17. A slider 19 is movably installed inside the slide groove 17. A support mechanism 18 is fixedly installed between the slider 19 and the slide groove 17. A limit post 21 is fixedly installed at one end of the slider 19. A limit hole 20 is installed at one end of the limit post 21. The limit hole 20 is opened on the inner wall of the fixing frame 3. Both the support mechanism 18 and the reset mechanism 13 are spring structures. The support mechanism 18 pushes the slider 19 to provide support force for the limit post 21, so that one end of the limit post 21 is installed inside the limit hole 20 to limit and fix the rotating seat 4.

[0023] When using this device, first rotate the movable seat 5 90 degrees at the bottom of the fixed seat 1. After the movable seat 5 rotates, the wiring holes 14 are exposed from both sides of the movable seat 5. After being exposed, the movable plate 7 is moved by the handle 8. When the movable plate 7 moves, it pushes the detection pen 6 out of the fixed hole 9 through the connecting plate 12. After the detection pen 6 is pushed, it is installed in the wiring hole 14 through the wire and plug for use. In use, the slider 19 is moved inside the slide groove 17. The movement of the slider 19 presses against the support mechanism 18. The slider 19 drives the limiting post 21 to move out of the limiting hole 20. After the limiting post 21 moves out, The fixed block 16 drives the rotating seat 4 to rotate on the fixed seat 1. When the rotating seat 4 rotates, it selects the range of values ​​for current, voltage and resistance. When the fixed block 16 corresponds to the appropriate value, the slider 19 is released. Under the push of the support mechanism 18, the slider 19 pushes the limiting post 21 into the interior of the limiting hole 20 to limit and fix the rotating seat 4, thereby avoiding the impact of the rotating seat 4 on the measurement during use. In addition, when the whole device is carried and moved, the movable plate 7 moves inside the fixed groove 10. The movement will expose the handle 8 from one end of the fixed seat 1. After exposure, it forms a holding point to hold and move the fixed seat 1 as a whole.
