[0036] The following is combined with Figures 1 to 3 This application is described in further detail.

[0037] The present application provides a voltage meter that is easy to observe, including: a voltage meter body 1, an observation connection 3 and an auxiliary clamping mechanism 5.

[0038] Specifically, Figure 1As shown, two terminals 2 are fixedly mounted on the voltmeter body 1, and the observation terminals 3 include two terminals. One end of the two observation terminals 3 can be detachably mounted on the corresponding terminals 2, and the other ends of the two observation terminals 3 are both mounted with terminal heads 4, which are arranged in parallel with the circuit to be measured; an auxiliary clamping mechanism 5 is installed on the observation terminal 3, which can press the observation terminal 3 and clamp the circuit to be measured, so that the terminal head 4 and the circuit to be measured are in a relatively stable state.

[0039] In a preferred embodiment of the present application, the auxiliary clamping mechanism 5 includes: a movable ring 51, a locking assembly 53, a positioning block 54, a positioning column 55 and a clamping assembly 57, wherein a through threading groove 52 is provided on the movable ring 51, and the movable ring 51 is sleeved on the observation wiring 3 through the threading groove 52, wherein the height H1 of the threading groove 52 is greater than the maximum width H2 of the terminal head 4, so as to facilitate the observation wiring 3 to move through the threading groove 52; the locking assembly 53 is installed on one side of the movable ring 51 and is connected to the threading groove 52, and is used to lock the observation wiring 3 inside the threading groove 52; one end of the positioning block 54 is installed on the movable ring 51, and the other end is provided with a plug-in hole; the positioning column 55 is plugged into the plug-in hole and locked by a locking stud 56 installed on the end face of the positioning block 54; the clamping assembly 57 is installed on the positioning column 55. The auxiliary clamping mechanism 5 is sleeved on the outside of the observation wiring 3 through a movable ring 51, and the movable ring 51 and the observation wiring 3 are locked and fixed by a locking assembly 53. The locking assembly 53 is pressed against the side wall of the wire threading groove 52 inside the wire threading groove 52, and the observation wiring 3 is clamped in the middle. At the same time, the position of the clamping assembly 57 can be adjusted by the positioning block 54 and the positioning column 55, which is convenient for controlling the distance between the auxiliary clamping mechanism 5 and the line to be measured. The positioning column 55 is locked in position by the spiral installation of the locking stud 56. The clamping assembly 57 is clamped on the line to be measured, so that the terminal head 4 and the line to be measured can be kept in a relatively stable position, which is convenient for the observation of the voltage meter.

[0040] In this embodiment, Figure 2As shown, the locking assembly 53 includes: a screw 531, a compression piece 532 and a rotating head 533, wherein the screw 531 is threadedly mounted on the movable collar 51; the compression piece 532 is mounted on one end of the screw 531 located inside the threading groove 52, and the compression piece 532 extends to the inside of the threading groove 52 to compress the observation wiring 3 and the side wall of the threading groove 52; the rotating head 533 is mounted on one end of the screw 531 located outside the movable collar 51, and the rotating head 533 rotates outside the movable collar 51. Advantageously, a handle is provided on the rotating head 533 for easy handholding. The locking assembly 53 generates a spiral displacement on the movable collar 51 through the screw 531, and the rotation of the rotating head 533 drives the screw 531 to rotate and displace outside the movable collar 51, and the displacement of the screw 531 drives the compression piece 532 to displace, thereby achieving compression and fixation of the observation wiring 3.

Then, the spring clip 572 is clamped on the circuit to be tested, so that the wiring head 4 and the circuit to be tested can be kept relatively stable, which is convenient for observing the wiring of the voltage meter. Advantageously, an insulating layer is provided on the outside of the spring clip 572 to prevent the operator from being electrocuted when clamping.

[0042] The voltage meter for easy observation of the present application can be used to measure the voltage of the circuit to be measured, and is convenient for the installation of the terminal head 4 during observation. The present application first measures the voltage through the voltmeter body 1, and then connects one end of the two observation terminals 3 to the corresponding terminal posts 2 respectively, and the other end of the observation terminal 3 is installed in parallel with the circuit to be measured to achieve voltage measurement and observation. At the same time, an auxiliary clamping mechanism 5 is clamped and installed on the observation terminal 3. The auxiliary clamping mechanism 5 is clamped on the circuit to be measured. After the length between the terminal head 4 and the circuit to be measured is reserved, the auxiliary clamping mechanism 5 is clamped and positioned with the observation terminal 3, and is clamped and positioned with the circuit to be measured at the same time, so that the terminal head 4 and the circuit to be measured are in a relatively stable state, which is more convenient for the voltage meter to observe the wiring of the circuit to be measured.
