[0038] In the existing electric energy meter, when the electric energy meter 5 is installed on the mounting slide rail 1, it may be difficult for the electric energy meter 5 to slide on the mounting slide rail 1 because the mounting slide rail 1 has not been used for a long time. The electric energy meter 5 may even be stuck on the mounting slide rail 1 and difficult to slide. The electric energy meter provided by the scheme can slide on the mounting slide rail 1 by pulling the sliding shell 2 before the electric energy meter is installed on the mounting slide rail 1. While the sliding shell 2 slides on the mounting slide rail 1, the mounting slide rail 1 is coated with lubricating oil through the spot-coated sealing ball 41 on the sliding tube 4. By coating the mounting slide rail 1 with lubricating oil, the lubrication degree of the electric energy meter 5 on the mounting slide rail 1 can be increased, and the electric energy meter 5 can be prevented from getting stuck during the sliding process on the mounting slide rail 1, so that the installation of the electric energy meter 5 can be more convenient, and the electric energy meter 5 can be saved to a certain extent. The installation time of the meter 5 can also be reduced to a certain extent, and the installation difficulty of the meter 5 can be reduced to a certain extent. Lubricating oil is applied to both sides of the installation slide rail 1 so that the installation slide rail 1 can be lubricated, so that the meter 5 can slide smoothly on the installation slide rail 1; it should be noted that the design that the sliding tube 4 can drive the spot-coating sealing ball 41 to slide can increase the spot coating area of ​​the spot-coating sealing ball 41 on the installation slide rail 1. At the same time, through the design of the spot-coating sealing ball 41 and the third spring 42, the sliding tube 4 drives the spot-coating sealing ball 41 to contact the installation slide rail 1, and the lubricating oil is applied to the installation slide rail 1. When the sliding tube 4 drives the spot-coating sealing ball 41 away from the installation slide rail 1, the spot-coating sealing ball 41, under the action of the third spring 42, will make the spot-coating sealing ball 41 block the oil outlet of the sliding tube 4 to prevent lubricating oil leakage, which can reduce the waste of lubricating oil and extend the service life of the equipment to a certain extent. When the electric meter 5 needs to be installed on the mounting rail 1, it is only necessary to pull the sliding shell 2 by hand to make the sliding shell 2 slide on the mounting rail 1. While the sliding shell 2 slides, the rotating wheel 3 on the sliding shell 2 will contact one side of the mounting rail 1. At the same time, the surface of the rotating wheel 3 is made of rubber material to increase friction. This rotating wheel 3 is a prior art, and those skilled in the art can select it according to actual needs, so that in the process of pulling the sliding shell 2 to slide, the rotating wheel 3 rotates, and the rotating wheel 3 rotates while driving the ratchet 31 to rotate together, and the rotating wheel 3 drives the ratchet 31 to rotate together. The rotation of the movable pawl 31 causes one end of the pawl 31 to contact the ratchet 34, so that the ratchet 34 drives the rotating column 35 to rotate together. At the same time, a first spring 32 is provided on one side of one end of the pawl 31. Through the provision of the first spring 32, one end of the pawl 31 can always contact the teeth on the ratchet 34. At the same time, the fixing plate 33 at one end of the first spring 32 can provide a stable fixation for the first spring 32, and can prevent the position of the first spring 32 from changing, so that the first spring 32 can always bring the pawl 31 to contact one side of the ratchet 34. When the rotating wheel 3 drives the rotating column 35 to rotate, the swing rod 36 at one end of the rotating column 35 will rotate. When the swing rod 36 rotates, it will drive the sliding tube 4 at one end to rotate together. When the sliding tube 4 rotates, the spot coating sealing ball 41 at one end of the sliding tube 4 will slide on the side wall inside the mounting slide rail 1. When the spot coating sealing ball 41 contacts the side wall inside the mounting slide rail 1, the spot coating sealing ball 41 will slide into the sliding tube 4, so that the lubricating oil in the sliding tube 4 can flow out, so that the lubricating oil can be applied to the inside of the mounting slide rail 1. When the sliding tube 4 rotates, the sliding ball 46 at the other end will slide in the sliding groove 24. At the same time, the sliding column 44 at one end of the sliding tube 4 will drive the lubricating oil bin 25 to rotate together. The engagement of the groove 26 provided in the lubricating oil bin 25 with the limiting protrusion 23 and the wrapping of the supporting round shell 22 on one side of the lubricating oil bin 25 enable the lubricating oil bin 25 to rotate smoothly on the inner side of the supporting round shell 22, so that the lubricating oil bin 25 will not deviate during the rotation process. At the same time, the lubricating oil bin 25 An annular sealing sheet 212 and a fourth spring 213 are provided inside the lubricating oil tank 25. With such a design, the lubricating oil in the lubricating oil tank 25 can be pushed to the oil outlet hole 27 under the action of the annular sealing sheet 212 and the fourth spring 213, so that the lubricating oil can enter the interior of the sliding tube 4 through the circular hole 214, the oil outlet pipe 210 and the hose 211. When the lubricating oil in the sliding tube 4 is reduced, the lubricating oil in the lubricating oil tank 25 will be squeezed to the oil outlet hole of the lubricating oil tank 25 under the action of the annular sealing sheet 212 and the fourth spring 213. 27, so that the lubricating oil in the lubricating oil tank 25 can be transported to the sliding tube 4 all the time, so that the inside of the sliding tube 4 can always have enough lubricating oil; at the same time, through the design of the pull rod 215 and the sealing cover 216, when the lubricating oil in the lubricating oil tank 25 is used up, it is only necessary to pull the pull rod 215 and then open the sealing cover 216, so that the pull rod 215 pulls the annular sealing sheet 212 to slide together, so that the newly added lubricating oil can be added to the lubricating oil tank 25. Through such a design, the lubricating oil in the lubricating oil tank 25 can be replenished; Through the design of the sealing block 29, when the subsequent sliding tube 4 drives the oil outlet pipe 210 to slide up and down, the sealing block 29 can be driven by the oil outlet pipe 210 to slide in the first slide groove 28. At the same time, the diameter of the oil outlet hole 27 is much larger than the circular hole 214. Through such a design, even when the sealing block 29 slides in the first slide groove 28, the circular hole 214 can always be connected with the oil outlet hole 27, so that the lubricating oil in the lubricating oil tank 25 can be continuously transported to the sliding tube 4. At the same time, the design of the sealing block 29 can prevent the lubricating oil in the lubricating oil tank 25 from leaking. At the same time, the sealing block 29 will not be separated from the first slide groove 28. Through such a design, the sealing block 29 can also block the oil outlet hole 27 all the time to prevent the lubricating oil from leaking out through the oil outlet hole 27. When the swing rod 36 drives the sliding tube 4 and the control rod 45 and the sliding ball 46 on the sliding tube 4 to slide to the transverse wave groove 241, the transverse wave groove 241 guides the control rod 45 and the sliding ball 46, so that the sliding ball 46 slides along the transverse undulation path of the transverse wave groove 241 under the guidance of the transverse undulation of the waves, so that the sliding tube 4 can drive the sliding column 44 to slide left and right in the middle of the oil outlet pipe 210, and the sliding column 44 will not be separated from the oil outlet pipe 210. At the same time, through the design of the hose 211, the sliding tube 4 will not affect the supply of lubricating oil in the sliding tube 4 during the process of sliding left and right and subsequent up and down sliding. At the same time, when the sliding tube 4 slides to the right, it will drive the spot coating sealing ball 41 to slide together, so that the spot coating sealing ball 41 does not contact the side wall of the mounting slide rail 1. When the coating sealing ball 41 does not contact the side wall of the mounting slide rail 1, the coating sealing ball 41, under the action of the third spring 42, will block one end of the sliding tube 4 to prevent the lubricating oil from leaking. Through such a design, when the coating sealing ball 41 slides on the side wall of the mounting slide rail 1, the side wall of the mounting slide rail 1 can be coated with lubricating oil. Such a design can save lubricating oil to a certain extent, and can lubricate the mounting slide rail 1 while using a small amount of lubricating oil. Through such a design, the inner side of the mounting slide rail 1 can be evenly coated with lubricating oil. At the same time, when the coating of the inner side of the mounting slide rail 1 is completed, when the sliding shell 2 slides, it drives the spreading plate 21 to flatten the coated lubricating oil, so that the lubricating oil can be evenly applied to the side wall of the mounting slide rail 1. When the swing rod 36 drives the sliding tube 4 and the control rod 45 and the sliding ball 46 on the sliding tube 4 to slide to the deep wave groove 242, through the undulating design of the deep wave groove 242, the sliding ball 46 slides along the ups and downs of the deep wave groove 242 under the guidance of the undulating waves, so that the sliding ball 46 drives the sliding tube 4 to slide up and down on one end of the swing rod 36 through the control rod 45. Through such a design, the spot sealing ball 41 can increase the area of ​​the side wall of the mounting slide rail 1, so that the lubricating oil can be evenly applied to the side wall of the mounting slide rail 1. When the sliding tube 4 slides up and down on one end of the swing rod 36, the sliding tube 4 can apply the clamping plates 39 on both sides. The second slide groove 37 is designed to prevent the clamping plate 39 from deviating during the sliding process, and at the same time prevent the clamping plate 39 from sliding out of the predetermined track, so that the clamping plate 39 can slide more smoothly. When the clamping plate 39 slides, the second spring 38 on one side of the clamping plate 39 can be deformed. Through such a design, the sliding tube 4 can be clamped in the middle by the two clamping plates 39 at all times, which can provide certain assistance for the sliding tube 4 when returning to its original position. At the same time, the clamping of the sliding tube 4 by the clamping plates 39 can also prevent the sliding tube 4 from being skewed, so that the spot coating sealing ball 41 on the sliding tube 4 can always be relatively vertical to spot coating the mounting slide rail 1. Through the combined design of the transverse wave groove 241 and the deep wave groove 242, when the sliding ball 46 slides in the transverse wave groove 241 and the deep wave groove 242, the spot-coated sealing ball 41 can increase the contact area with the side wall of the mounting rail 1, and at the same time, the spot-coated sealing ball 41 can spot-coat the side wall of the mounting rail 1, thereby increasing the contact area and reducing the loss of lubricating oil. By applying lubricating oil to the side wall inside the mounting rail 1, when the electric meter 5 is installed on the mounting rail 1, the electric meter 5 can slide more smoothly without jamming, and at the same time, the inner side of the mounting rail 1 can be prevented from rusting. After lubricating the side wall of the mounting slide rail 1, pull the sliding shell 2 back to slide. When pulling the sliding shell 2 back to slide, the rotating wheel 3 is reversed. Through the reversal of the rotating wheel 3, one end of the pawl 31 does not interfere with the teeth of the ratchet 34, so that the rotating wheel 3 will not cause the rotating column 35 to rotate while reversing. Through such a design, when the sliding shell 2 is slid back, the side wall of the mounting slide rail 1 will not be coated with excess paint again.
