Energy meter testing is the basis for power supply companies to monitor and manage power quality, and is also the focus of power market supervision. Through energy meter testing, the accuracy and reliability of energy metering can be ensured, energy metering errors can be avoided, and customers' electricity costs can be reasonably calculated and charged. When teaching energy meter testing, a practical training platform will be needed to facilitate students to observe more carefully, which improves the efficiency of energy meter testing teaching;

[0003] In the "A training platform for electric energy metering wiring operation" with the patent CN220873147U, an operation panel is included, the upper surface of the operation panel is provided with a placement slot, the upper end of the operation panel behind the placement slot is rotatably connected to a training panel via a hinge, a training mechanism is installed at the front end of the training panel, the size of the training panel matches the size of the placement slot, a card plate is installed at the upper end of the training panel, a fixing mechanism is installed in front of the placement slot, and a supporting mechanism is installed at the upper end of the operation panel behind the placement slot. The utility model provides a placement slot on the operation panel and rotatably connects the training panel to the inside of the placement slot, so as to facilitate the storage of the training mechanism on the training panel fan, and at the same time uses a fixing mechanism to fix the card plate on the training panel, so as to effectively prevent external dust from falling on the surface of the electric energy metering wiring operation equipment, and does not need to be cleaned frequently;

[0004] However, when the training platform is used for teaching, because the traditional training platform is connected through a wiring harness when testing the electric energy meter, and most of the traditional wiring harnesses are directly inserted into the terminal block, and there is no positioning mechanism to clamp and position the wiring harness, which will cause the wiring harness to loosen and fall off due to dragging during the later test, which is not convenient for the stable teaching use of the later electric energy meter test training platform;

[0005] Therefore, we proposed an electric energy meter test training platform that can solve the above problems well. Utility Model Content

[0006] The purpose of the utility model is to provide an electric energy meter test training platform to solve the problem raised by the above background technology that traditional training platforms on the market are connected through wiring harnesses when testing electric energy meters. However, most of the traditional wiring harnesses are directly inserted into the terminal block, and there is no positioning mechanism to clamp and position the wiring harness, which will cause the wiring harness to loosen and fall off due to dragging during later testing, making it inconvenient for stable teaching and use of the electric energy meter test training platform in the later stage.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric energy meter test training platform, comprising a body, a display screen is provided in a slot on the front side of the body, and wiring sockets are provided on both sides of the display screen, and the two wiring sockets are screwed on both ends of the front side of the body, and a placement table is provided above the front side of the body;

The anti-skid pad can increase the friction between the positioning plate and the wiring harness to prevent the wiring harness from loosening and falling off due to dragging during later use.

[0010] Preferably, the terminal block has grooves at both upper and lower ends thereof, through which a pressing rod is slidably installed, and the outer sides of each two pressing rods are connected to a transmission gear through a rack meshing, and the outer sides of the two transmission gears are also connected to a moving rod through a rack meshing, each moving rod is slidably installed at the upper and lower ends of the terminal block, and the inner end of each moving rod is connected to a positioning plate through a screw, and the two pressing rods can be pressed to drive the positioning plates connected to the inner ends of the two moving rods to retract and move through the two transmission gears, and then the wiring harness can be quickly disassembled, assembled and replaced.

[0011] Preferably, each transmission gear is grooved inside and provided with a torsion spring, and each torsion spring has the same structure, and the inner end of each torsion spring is connected to the inner wall of the terminal block, so that the position of the transmission gear after rotation can be easily elastically reset by the elastic force of the torsion spring itself.

[0012] Preferably, the placement table has a slot on the top on which a push rod is slidably installed, and a cleaning sponge is installed on the bottom of the push rod through a row of positioning buckles, and the bottom of the cleaning sponge is snugly connected to the placement table, and the placement table has slots on the front and back sides thereof with tension springs, and the two tension springs are symmetrically arranged about the transverse center line of the placement table, and the outer ends of the two tension springs are connected to the push rod, and the elastic force of the two tension springs themselves can be used to elastically reset the position of the push rod after pushing, so as to facilitate repeated cleaning and use in the later period.

[0015] (2) Furthermore, by using slots at both ends of the wiring seat to penetrate and slide through a pressing rod, and then connecting the outer sides of the two pressing rods with transmission gears through rack meshing, the two transmission gears can be driven to rotate when the two pressing rods are pressed to retract and move, and then the two transmission gears will also drive the two moving rods to retract and move through the two racks, so that the two positioning plates can be separated from the wiring harness, so as to facilitate the rapid disassembly and separation of the wiring harness at a later time, and the operation is more time-saving and labor-saving;

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] This utility provides the following technical solutions:

[0029] Embodiment 1, in order to solve the problem that the existing wiring seat 3 does not have a positioning mechanism to position and clamp the inserted wiring harness, thereby causing the wiring harness to loosen and fall off due to dragging, discloses:

[0030] The body 1 has a display screen 16 disposed in a slot on the front side thereof, and wiring sockets 3 are respectively disposed on both sides of the display screen 16, and the two wiring sockets 3 are both screw-mounted at both ends of the front side of the body 1, and a placement table 2 is disposed above the front side of the body 1;

[0031] It also includes: two wiring blocks 3 with the same structure, and wire insertion holes 4 are provided at both upper and lower ends of the two wiring blocks 3, and the four wire insertion holes 4 are connected with wiring harnesses through them, and the wiring blocks 3 are provided with positioning plates 5 at both upper and lower ends, and each positioning plate 5 is semicircular in shape, and at the same time, there are wiring harnesses corresponding to the inner sides of every two positioning plates 5.

[0032] The inner side of each positioning plate 5 is fitted with an anti-skid pad 6 , and each anti-skid pad 6 is made of rubber material, and the inner sides of every two anti-skid pads 6 are fitted and connected to the outer side wall of the wiring harness.

[0033] like Figure 1-Figure 3 As shown, when the wiring harness is inserted into the interior of the terminal block 3 through the wire insertion hole 4, the two positioning plates 5 will be connected to the outer wall of the wiring harness through the two anti-skid pads 6. The two anti-skid pads 6 can be used to increase the friction between the terminal block 3 and the wiring harness, thereby preventing the wiring harness from loosening and falling off due to dragging during testing and teaching in the later stage, thereby improving the stability of testing and teaching.

[0034] Embodiment 2 is different from Embodiment 1 in that the wiring harness can be quickly disassembled and replaced, which is more practical and saves time and effort. It discloses:

[0035] The terminal block 3 has grooves at both upper and lower ends thereof through which a pressing rod 7 is slidably installed, and the outer sides of each two pressing rods 7 are meshedly connected with a transmission gear 8 through a rack 10, and the outer sides of the two transmission gears 8 are also meshedly connected with a moving rod 9 through the rack 10, each moving rod 9 is slidably installed through the upper and lower ends of the interior of the terminal block 3, and the inner end of each moving rod 9 is connected to a positioning plate 5 through a screw, and a torsion spring 11 is grooved inside each transmission gear 8, and each torsion spring 11 has the same structure, and the inner end of each torsion spring 11 is connected to the inner wall of the terminal block 3.

[0036] like Figure 1-Figure 5As shown, when the wiring harness needs to be quickly disassembled and replaced, it is only necessary to manually press the two pressing rods 7 to retract and move the position. At this time, the racks 10 arranged on the outside of the two pressing rods 7 will simultaneously drive the two transmission gears 8 to rotate. Because the outsides of the two transmission gears 8 are also meshed with the moving rod 9 through the rack 10, the two positioning plates 5 can be driven to retract and move while pressing the two pressing rods 7 to retract them. Subsequently, the wiring harness can be quickly disassembled and replaced. Finally, the elastic force of the two torsion springs 11 can be used to elastically reset the positions of the two transmission gears 8 after rotation, so as to facilitate subsequent repeated operations and better practicality.

[0037] Embodiment 3 is different from Embodiment 2 in that dust and impurities sticking to the surface of the placement table 2 can be cleaned and wiped to prevent dust and impurities from sticking to the surface of the placement table 2 and affecting the subsequent test and teaching use. The following is disclosed:

[0038] The placing table 2 has a slot on the top on which a push rod 12 is slidably installed, and a cleaning sponge 13 is installed on the bottom of the push rod 12 through a row of positioning buckles 14, and the bottom of the cleaning sponge 13 is closely connected to the placing table 2. The placing table 2 has slots on both the front and back sides inside and tension springs 15 are arranged symmetrically about the transverse center line of the placing table 2, and the outer ends of the two tension springs 15 are connected to the push rod 12.

[0039] like Figure 1-Figure 7 As shown, after the placement table 2 has been used for a long time, its surface will be sticky with dust and impurities from the outside world. If it is not cleaned for a long time, it will affect the subsequent test use. At this time, you only need to manually push the push rod 12 to drive the cleaning sponge 13 to move its position, and then the cleaning sponge 13 will move and clean the dust and impurities stuck on the surface of the placement table 2. At this time, the elastic force of the two tension springs 15 can be used to elastically reset the position of the push rod 12 after pushing, so as to facilitate the reciprocating cleaning and wiping of the placement table 2, thereby improving the cleanliness and hygiene of the training platform.
