[0002] The power detector is a type of power monitoring equipment. It refers to a device that conducts test, verification, inspection and acceptance of power production and grid operation. It provides reliable protection for the safety and reliability of power operation. The power monitor can directly replace conventional power transmitters and measuring instruments. When the power monitor is in use, it needs to be installed in the required position through a positioning structure. Therefore, we have launched a power monitor with a positioning structure.

[0003] The existing technology has the following problems: the existing power monitor clamps the protruding block by rotating the screw and the baffle, thereby completing the installation of the power monitor. However, during the installation process, the screws need to be tightened one by one, resulting in low installation efficiency. Utility Model Content

[0020] See also Figures 1 to 4 The utility model provides a technical solution: an electric power monitor with a positioning structure, including an installation box 1, a monitor body 2 is provided on one side of the installation box 1, a pull rod 4 is rotatably connected between the two sides of the installation box 1, and a positioning component 5 is provided inside the installation box 1.

[0021] In this embodiment, Figure 3 and Figure 4 As shown, the positioning assembly 5 includes a ratchet 501 rotatably connected to both sides of the installation box 1, a worm 502 is fixedly connected to the middle of the ratchet 501, the worm 502 is rotatably connected to one side of the fixed plate 503, a slide groove 504 is provided on the top of one side of the fixed plate 503, a rack 505 is slidably connected inside the slide groove 504, one end of the rack 505 is fixedly connected to a connecting frame 506, the end of the connecting frame 506 is fixedly connected to a positioning rod 507, the positioning rod 507 extends away from one end of the connecting frame 506 to the outside of the installation box 1 and is connected to the abutment 508, a worm wheel 509 is meshed with one side of the worm wheel 502, a support shaft 5010 passes through the middle of the worm wheel 509, and a gear 5011 is fixedly connected to the middle of the support shaft 5010. The installation box 1 is away from the monitor itself. A baffle 3 is fixedly connected to one side corner of the body 2, and the baffle 3 corresponds to the abutment 508 one by one; the ratchet 501 and the worm 502 are driven to rotate by pulling the pull rod 4 downward, and the worm 502 drives the worm wheel 509 meshing with it to rotate with the support shaft 5010 as the axis, and the support shaft 5010 drives the gear 5011 to rotate, and the gear 5011 drives the rack 505 to slide linearly along the slide groove 504, and the rack 505 drives the positioning rod 507 to move toward the baffle 3 through the connecting frame 506 until the external mounting plate is fixed between the baffle 3 and the abutment 508, completing the fixation of the monitor body 2. Compared with the traditional method of fixing by twisting the screw, fixing by pulling down the pull rod 4 is faster, thereby improving the installation speed of the monitor body 2.

[0022] In this embodiment, Figure 2 and Figure 3As shown, the gear 5011 is engaged with the rack 505, the cross-section of the rack 505 is "T"-shaped, the two ends of the fixed plate 503 are connected to the two inner walls of the installation box 1, the cross-section of the slide 504 is "T"-shaped, and the internal dimension structure of the slide 504 is consistent with the external dimension structure of the rack 505; this structure enables the rack 505 to slide inside the slide 504 while preventing the rack 505 from falling out of the slide 504.

[0023] In this embodiment, Figure 1 and Figure 4 As shown, the end of the pull rod 4 is welded with a shell 401, and the inner wall of the shell 401 is respectively provided with a connecting shaft 402 and a torsion spring 403, and the end of the connecting shaft 402 away from the inner wall of the shell 401 is fixedly connected to a pawl 404, and the end of the pawl 404 away from the connecting shaft 402 is in contact with the outer side of the ratchet 501; when the pull rod 4 is pulled to rotate around the central axis of the shell 401, the pawl 404 in the shell 401 will synchronously drive the ratchet 501 to rotate, thereby driving the entire positioning assembly 5 to operate and position the monitor body 2. When the monitor body 2 is fixed, the pull rod 4 may be located directly in front of the monitor body 2. In order to prevent the pull rod 4 from interfering with the normal operation of the monitor body 2, the pull rod 4 needs to be rotated upward so that the pull rod 4 is located directly above the installation box 1, and in this process, the pawl 404 will not drive the ratchet 501 to rotate, and will not affect the fixation of the monitor body 2 by the abutment head 508.

[0024] The use method and advantages of this utility model: When the power monitor with a positioning structure is used, the working process is as follows:

[0025] Place the external mounting plate between the abutment 508 and the baffle 3, then repeatedly pull down the pull rod 4, use the pawl 404 in the pull rod 4 to drive the ratchet 501 to rotate, thereby driving the transmission part to move the connecting frame 506 toward the baffle 3, so that the abutment 508 fixes the external mounting plate between the abutment 508 and the baffle 3. Compared with the traditional method of fixing by twisting the screw, this structure uses the pull rod 4 to pull down to fix faster, improves the installation speed of the monitor body 2, and completes the fixation of the four corners at the same time without twisting the screws one by one for fixation. At the same time, the worm gear 509 and the worm 502 are self-locking, which effectively prevents the loosening of the monitor body 2.
