[0002] An LCR tester is an instrument that, based on the equivalent circuit model of the element to be tested, measures the impedance of the element to a signal by applying an alternating current signal or a direct current signal with a specific frequency, and then calculates the inductance value, capacitance value, and resistance value.

[0003] Currently, the angle of the existing LCR tester itself is mostly fixed, that is, integrated with the tester. During actual use, due to factors such as the working environment and the habits of the operators, the fixed display angle makes it difficult to observe data, increases work fatigue, and requires the staff to change positions, etc. Therefore, there is an urgent need for a display angle adjusting mechanism for an LCR tester. Content of the Utility Model

A display module is installed in the notch through side chute limits. One side of the upper end of the display module is rotatably installed with a second plate member. One side of the second plate member is rotatably installed with a first plate member. One side of the first plate member is limited and slidably installed on the upper end of the LCR tester body through a fixed convex block.

[0007] The display module, the first plate member, and the second plate member are connected by damping rotating shafts.

[0008] In addition, preferably, wave-shaped protrusions are provided on the inner walls of the side chutes on both sides of the notch opened on one side of the LCR tester body, and a display module is installed in the side chutes through a top pin limit and sliding.

[0009] In addition, preferably, telescopic grooves are opened on both sides of the bottom of the display module. A top pin is installed in the telescopic grooves through limit sliding. One side of the top pin is connected to the inner wall of the telescopic groove through a spring.

[0010] In addition, preferably, a first slider is installed on both sides of the upper part of the display module, and the first slider is correspondingly clamped with a card slot opened on one side of the LCR tester body.

[0012] In addition, a preferred structure is that an arc-shaped guiding slope is provided at the top of the side sliding groove.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, by pulling and rotating the display module and cooperating with the settings of components such as the first plate member, the second plate member, and the damping rotating shaft, the multi-angle rotation function of the display module is realized.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1-6, A display angle adjustment mechanism for an LCR tester, including the LCR tester body 1. A notch is opened on one side of the middle of the LCR tester body 1. A display module 2 is installed in the notch through side sliding grooves 6 in a limited way. One side of the upper end of the display module 2 is rotatably installed with a second plate member 5. One side of the second plate member 5 is rotatably installed with a first plate member 4. One side of the first plate member 4 is installed in a limited and sliding way on the upper end of the LCR tester body 1 through a fixed convex block 41;

[0024] Further, the display module 2, the first plate member 4, and the second plate member 5 are connected by a damping rotating shaft 8. The damping rotating shaft 8 provides a certain resistance when the first plate member 4 and the second plate member 5 rotate due to its material characteristics, so that the plate members can stop stably and controllably at a specific position during the rotation process.

[0025] Further, on both sides of the notch opened on one side of the LCR tester body 1, side sliding grooves 6 are opened. The inner wall of the side sliding groove 6 is provided with wavy protrusions, and the display module 2 is installed in the side sliding groove 6 through a top pin 23 in a limited and sliding way.

[0026] Further, telescopic grooves 22 are opened on both sides of the bottom of the display module 2. A top pin 23 is installed in the telescopic groove 22 in a limited and sliding way. One side of the top pin 23 is connected to the inner wall of the telescopic groove 22 through a spring 24.

[0027] Further, a first slider 21 is installed on both sides of the upper part of the display module 2. The first slider 21 is correspondingly clamped with a clamping groove 7 opened on one side of the LCR tester body 1.

[0028] Further, a top sliding groove 3 is opened on one side of the top end of the LCR tester body 1. The bottom wall of the top sliding groove 3 is provided with wavy protrusions, and the first plate member 4 is installed in the top sliding groove 3 through a fixed convex block 41 in a limited and sliding way. The sliding stability and controllability of the first plate member 4 can be increased through the wavy protrusions.

[0029] Further, an arc-shaped guide slope is provided at the top of the side sliding groove 6. The arc-shaped guide slope is flush with the notch opened on one side of the LCR tester body 1 and is used for the export function of the display module 2.

[0030] In this embodiment, by pulling the display module 2, the first slider 21 on its upper part is disengaged from the clamping groove 7 opened on one side of the LCR tester body 1, so that the display module 2 is no longer restricted by the clamping groove 7. By rotating the display module 2, its angle rotation function can be realized.

[0031] At the same time, the height of the display module 2 can be changed by continuing to pull the display module 2 upward. And when pulled to a certain distance, the display module 2 is disengaged from the side sliding groove 6 to realize the free movement function. At this time, in cooperation with the rotation connection mechanism of the second plate member 5 and the damping rotating shaft 8, the free rotation function of the display module 2 can be realized.

[0032] Among them, during the movement of the display module 2, the top pin 23 arranged at the bottom of the display module 2 slides into the side slide groove 6, and is squeezed and contacted with the wavy protrusion provided in the side slide groove 6 to obtain a limiting function, and during the movement, the top pin 23 is adaptively retracted and extended by the spring 24. At the same time, after moving to a certain distance, the top pin 23 is separated from the top of the side slide groove 6 and is no longer limited by the side slide groove 6. At this time, the display module 2 can be turned outward by bending the display module 2 to separate from the outside of the LCR tester body 1.

[0033] Among them, in actual use, the display module 2, plate 1 4, and plate 2 5 are connected by a damping shaft 8. The damping shaft 8 provides a certain resistance when plate 1 4 and plate 2 5 rotate due to its material properties, so that the plates can stop at a specific position smoothly and controllably during the rotation process, and plate 1 4 slides in the top slide groove 3 through the fixed protrusion 41, thereby realizing the adjustment function of different angles and positions of the display module 2.

[0034] Among them, during the sliding process of the plate 1 4 , the fixed protrusion 41 is squeezed and contacted with the rubber pad 31 in the top slide groove 3 , so that the plate 1 4 has a certain damping during the movement to achieve movement stability and controllability.

[0035] In the utility model, the display module 2 is pulled out and rotated, and the panel 1 4, the panel 2 5, the damping shaft 8 and other components are arranged in coordination to realize the multi-angle rotation function of the display module 2. At the same time, the internal damping shaft 8 and the rubber pad 31 are arranged to improve the stability during rotation, maintain the rotation angle, improve the convenience of angle adjustment, and increase the observation portability and the use experience.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
