[0001] This utility model relates to the technical field of electricity meter testing equipment, and in particular to a single-phase module smart electricity meter testing device. Background Technology

[0002] A single-phase smart meter is a device used to measure and monitor energy consumption, typically used in residential, commercial, and small industrial applications. A single-phase smart meter testing device is a tool or apparatus used to test and verify the performance of a single-phase smart meter. Its main function is to ensure the metering accuracy and normal function of the meter, and it is commonly used during the production, inspection, and maintenance of the meter. For example, Chinese Patent No. CN207924123U discloses a novel single-phase smart meter testing device. In this design, the power cord, anode connector, and cathode connector are concealed inside the testing device during use. However, in actual use, the cable needs to be slowly pulled out of the inner slot of the testing device. If the cable is tangled or twisted in the inner slot, extra time is required to straighten it during removal, potentially causing damage. When placing the cable into the slot, if the space inside the slot is typically small and the cable is long, it needs to be inserted section by section, resulting in significant time wasted in both placement and removal within the slot. Utility Model Content

[0003] The purpose of this invention is to address the problem that in practical use, when cables need to be slowly pulled out of or placed into the groove of the testing device, a lot of time is wasted in both retrieving and placing them in the groove. This invention proposes a single-phase module smart energy meter testing device.

[0005] Optionally, the reset mechanism includes a pair of slide rails fixedly connected in the inner groove, a slider slidably connected to the middle of the slide rails, a pair of annular retaining plates fixedly sleeved on the middle of the slider to hold the connecting wire, a sliding plate slidably connected to the pair of slide rails, a pair of retaining brackets movably sleeved with the slider on the side of the sliding plate near the slider, a push spring provided inside the inner groove, one end of the push spring fixedly connected to the inner wall of the inner groove, and the other end of the push spring fixedly connected to the sliding plate.

[0006] Optionally, the locking mechanism includes a pressing block slidably connected in a sliding groove. One end of the pressing block inserted into the sliding groove has a sliding hole. A locking rod with one end movable through the inner groove is slidably connected in the sliding hole. Both ends of the slider have fixed locking grooves for the end of the locking rod to be engaged.

[0007] Optionally, the locking mechanism further includes a tail plate fixedly connected to the other end of the locking rod. A return spring is fixedly connected to the end of the tail plate away from the locking rod. The end of the return spring away from the tail plate is fixedly connected to the return spring. The end of the pressing block near the locking rod is provided with an inclined surface that abuts against the tail plate and drives the locking rod to retract into the sliding groove.

[0008] Optionally, both ends of the connecting line are fixedly fitted with reinforcing sleeves, one of which is fixedly connected to the detection connector, and the other is fixedly connected to the inner wall of the inner groove.

[0009] Optionally, one end of the lever inserted into the fixed slot is provided with a hemispherical plug.

[0010] Optionally, the pair of reset mechanisms and locking mechanisms are symmetrically arranged in the middle of the host.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This invention utilizes the cooperation of an inner groove, connecting wire, reset mechanism, and locking mechanism to allow the connecting wire to be quickly pulled out or retracted within the inner groove. During extraction, it not only prevents the connecting wire from becoming tangled, maintaining cleanliness and safety around the equipment, but also avoids excessive time wasted when placing the connecting wire back into the inner groove, making the process quick and efficient.

[0025] Example

[0026] like Figures 1 to 5 As shown, the present invention proposes a single-phase module smart energy meter testing device, including a main unit 1 and a testing connector 12. The testing connector 12 is used for direct connection to a power supply or load device, facilitating installation and disassembly. It also includes: a pair of inner grooves 11 formed within the main unit 1, one end of which is provided with a connecting line 16 fixedly connected to the testing connector 12. Both ends of the connecting line 16 are fixedly fitted with reinforcing sleeves 2, one of which is fixedly connected to the testing connector 12, and the other is fixedly connected to the inner wall of the inner groove 11; a pair of reset mechanisms, disposed within the inner grooves 11, to automatically retract the pulled-out connecting line 16; and a pair of sliding grooves 111 on the main unit 1 corresponding to the testing connector 12. Each sliding groove 111 has a locking mechanism inside which the pulled-out connecting line 16 is fixed in a designated position. The reset mechanism and the locking mechanism are symmetrically arranged in the middle of the main unit 1.

[0027] Furthermore, the reset mechanism includes a pair of slide rails 13 fixedly connected within the inner groove 11. A slider 14 is slidably connected to the middle of the slide rails 13. One end of the locking rod 114, which inserts into the fixed slot 141, is provided with a hemispherical plug. The hemispherical plug makes it easier and less strenuous for the end of the locking rod 114 to insert into the fixed slot 141. A pair of annular locking plates 15, which hold the connecting line 16, are fixedly sleeved in the middle of the slider 14. A sliding plate 18 is also slidably connected to the pair of slide rails 13. Arc-shaped grooves are provided on both the upper and lower surfaces of the sliding plate 18, which hold the connecting line 16 to prevent obstruction of its sliding. A pair of locking brackets 19, which are movably sleeved with the slider 14, are fixedly connected to the side of the sliding plate 18 near the slider 14. The locking brackets 19 support the slider 14 to slide horizontally in the direction of the sliding of the pair of slide rails 13. A push spring 17 is provided inside the inner groove 11. The push spring 17 causes the compressed sliding plate 18 to automatically return to its original position. One end of the push spring 17 is fixedly connected to the inner wall of the inner groove 11, and the other end of the push spring 17 is fixedly connected to the sliding plate 18.

[0028] The locking mechanism includes a pressing block 112 slidably connected in the sliding groove 111. One end of the pressing block 112 inserted into the sliding groove 111 has a sliding hole 113. A locking rod 114 with one end movable through the inner groove 11 is slidably connected in the sliding hole 113. Both ends of the slider 14 have fixed locking grooves 141 for the end of the locking rod 114 to be locked in.

[0029] Furthermore, the locking mechanism also includes a tail plate 115 fixedly connected to the other end of the locking rod 114. A return spring 116 is fixedly connected to the end of the tail plate 115 away from the locking rod 114. The function of the return spring 116 is to cause the tail plate 115 to drive the locking rod 114 to automatically insert into the fixed locking slot 141, thereby fixing the slider 14 in the designated position. The end of the return spring 116 away from the tail plate 115 is fixedly connected to the return spring 116. The end of the pressing block 112 near the locking rod 114 is provided with an inclined surface that abuts against the tail plate 115 and drives the locking rod 114 to retract into the sliding groove 111. The function of the inclined surface is that the tail plate 115 being abutted will drive the locking rod 114 to retract into the sliding groove 111.

[0030] In this embodiment, when a single-phase module smart energy meter detection device is required, such as... Figure 1 As shown, when it is necessary to pull one end of the connecting wire 16 from the inner groove 11, simply pull the corresponding testing connector 12 to move the connecting wire 16. The middle part of the connecting wire 16 pulls the slider 14 to slide along the slide rail 13 until the end of the slider 14 abuts against the locking rod 114. At this time, the corresponding pressing block 112 can be pressed into the sliding groove 111. The inclined surface of the pressing block 112 abuts against the tail plate 115, causing the tail plate 115 to drive the locking rod 114 back into the sliding groove 111. Then, pull the connecting wire 16 again to make the slider 14 completely abut against the inner wall of one end of the inner groove 11. After that, release the pressed pressing block 112. The tail plate 115, through the elastic thrust of the return spring 116, causes the tail plate 115 to drive the locking rod 114 into the inner groove 11 and then into the fixing slot 141 at the end of the slider 14. At this point, the slider 14 cannot move, and the connecting wire 16 has reached its limit of extension from the inner groove 11. When the connecting wire 16 is no longer needed, simply press the pressing block 112 again to disengage the locking rod 114 from the fixing slot 141 at the end of the slider 14. Finally, the sliding plate 18, through the elastic force of the spring 17, causes the sliding plate 18 to drive a pair of locking brackets 19 to lock the slider 14 and push it to the inner wall of the other end of the inner groove 11, thereby causing the end of the connecting wire 16 to move the detection connector 12 to the position as described above. Figure 1 The status shown is convenient and quick.
