[0032] See attached document Figure 1-4 A quick-installation power meter includes a power meter body 1, a mounting groove 4 on one side of the power meter body 1, a conductive groove 5 at the bottom of the inner wall of the mounting groove 4, spring telescopic rods 6 on both sides of the inner wall of the mounting groove 4, a retaining strip 7 at one end of the spring telescopic rod 6, and a limit ring on the inner side of the conductive groove 5.

[0033] The mounting cover structure 8 includes a mounting cover body 801 and a conductive post 810. An auxiliary spring 812 is provided at one end of the conductive post 810, and a conductive block 813 is provided at one end of the auxiliary spring 812. The cross-section of the conductive block 813 is set as an isosceles trapezoid, and the number of conductive blocks 813 is set to multiple. Multiple conductive blocks 813 are arranged in a ring array on the outer wall of the conductive post 810.

[0034] The wire is placed inside the conductive post 810 and fixed. Then, the power meter body 1 is brought into contact with the mounting cover body 801, so that the conductive post 810 is directly inserted into the conductive groove 5. The conductive block 813 passes through the limiting ring on the inner side of the conductive groove 5 and fits against the outer wall of the limiting ring, thereby connecting the wire to the power meter body 1.

[0035] Furthermore, a display screen 2 is provided on the outer wall of the power meter body 1, and a sealing strip 3 is provided on the outer side of the power meter body 1. The sealing strip 3 is connected to the equipment to insulate and seal the power meter body 1 installed on the equipment.

[0036] Furthermore, the number of the retaining strips 7 is set to multiple, and the multiple retaining strips 7 are evenly distributed on both sides of the inner wall of the mounting groove 4. The sides of the retaining strips 7 are inclined. The mounting cover plate body 801 is set on the outer wall of the power meter body 1. Bolt holes 802 are opened on both sides of the mounting cover plate body 801. A bracket 803 is provided on the inner side of the mounting cover plate body 801. A guide block 804 is provided at one end of the bracket 803. When the power meter body 1 needs to be installed, the mounting cover plate body 801 is first installed on the equipment. Inside the mounting cover 801, the power meter body 1 is inserted into the outer wall of the mounting cover 801. The retaining strip 7 contacts the guide block 804 and is pushed inward by the guide block 804 to squeeze the spring telescopic rod 6. Then, the outer wall of the guide block 804 fits against the inner side of the retaining strip 7 to lock the retaining strip 7 in place. This fixes the power meter body 1 inside the mounting cover structure 8. When the power meter body 1 needs to be removed for replacement, simply pull the power meter body 1 outward to disengage the retaining strip 7 on one side of the power meter body 1 from the guide block 804.

[0037] Furthermore, the guide block 804 is hexagonal, with a mounting hole 805 and an auxiliary groove 806 inside. A conductive post 810 is slidably connected inside the mounting hole 805, and a tension spring 811 is provided between the conductive post 810 and the mounting hole 805. A spring slide 807 is slidably connected to the inner wall of the auxiliary groove 806, and a return spring 808 is provided between the spring slide 807 and the auxiliary groove 806. A fitting ring 809 is provided on the inner side of the spring slide 807, and the fitting ring 809 is slidably connected to the mounting hole 805. The middle of the inner wall of the mounting hole 805 is inclined. When the power meter body 1 is not installed, the wire is first installed... The wire is inserted into the mounting hole 805. The spring slide 807 is released, and the reset spring 808 moves the spring slide 807 downward. The contact ring 809 at one end of the spring slide 807 slides on the inclined surface of the inner wall of the mounting hole 805, so that the contact ring 809 engages with the guide of the inner wall of the mounting hole 805 to fix the wire. One end of the wire is connected to the conductive post 810. When the mounting cover structure 8 is connected to the power instrument body 1, the conductive post 810 is also inserted into the conductive groove 5. The conductive block 813 passes through the limiting ring on the inner wall of the conductive groove 5 and then the auxiliary spring 812 pushes the conductive block 813 to reset, so that the conductive block 813 is in contact with the inner wall of the conductive groove 5, realizing the information transmission and power supply to the power instrument body 1 after installation.

[0038] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
