[0043] When the existing 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 easy-to-install 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 by the spot-coated sealing ball 41 on the sliding tube 4. By coating the mounting slide rail 1 with lubricating oil, the lubrication 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, making the installation of the electric energy meter 5 more convenient and saving energy to a certain extent. The utility model relates to a sliding member 1 having a plurality of sliding members 41 and a plurality of sliding members 42, wherein the plurality of sliding members 41 are provided with a plurality of sliding members 42, and the plurality of sliding members 41 are provided with a plurality of sliding members 42.

[0044] When it is necessary to install the electric meter 5 on the installation slide rail 1, only need to pull the slide shell 2 by hand, make the slide shell 2 slide on the installation slide rail 1, the rotating wheel 3 on the slide shell 2 will contact with one side of the installation slide rail 1 at the same time of sliding, at the same time the outer surface of the rotating wheel 3 is rubber material which increases the friction, this rotating wheel 3 is prior art, the person skilled in the art can select according to actual needs, make the rotating wheel 3 rotate in the process of pulling the slide shell 2 to slide, the pawl 31 rotates together with the rotating wheel 3 at the same time of the rotating wheel 3 rotating, the pawl 31 rotates through the rotating wheel 3, make one end of the pawl 31 resist the ratchet wheel 34, so that the ratchet wheel 34 drives the rotating column 35 to rotate together, at the same time one side of one end of the pawl 31 is provided with the first spring 32, through the setting of the first spring 32, one end of the pawl 31 can always resist the tooth on the ratchet wheel 34, at the same time the fixed sheet 33 at one end of the first spring 32 can provide stable fixation for the first spring 32, can prevent the position of the first spring 32 from changing, make the first spring 32 can always resist one side of the ratchet wheel 34 with the pawl 31;

[0045] When the rotating wheel 3 drives the rotating column 35 to rotate, the rocker 36 at one end of the rotating column 35 will rotate. When the rocker 36 rotates, it will drive the sliding tube 4 at one end to rotate together. When the sliding tube 4 rotates, the 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 coating sealing ball 41 contacts the side wall inside the mounting slide rail 1, the 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 On the side wall of the side, the sliding tube 4 rotates and drives the sliding ball 46 at the other end to slide in the sliding groove 24. At the same time, the sliding column 44 at one end of the sliding tube 4 drives the lubricating oil tank 25 to rotate together. The engagement of the groove 26 provided in the lubricating oil tank 25 with the limiting protrusion 23 and the wrapping of the supporting circular shell 22 on one side of the lubricating oil tank 25 enable the lubricating oil tank 25 to rotate smoothly inside the supporting circular shell 22, so that the lubricating oil tank 25 will not deviate during the rotation process. At the same time, the lubricating oil tank 25 An annular sealing piece 212 and a fourth spring 213 are provided inside the lubricating oil tank 25. Through 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 piece 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 piece 212 and the fourth spring 213. 27, so that the lubricating oil in the lubricating oil tank 25 can be continuously transported into the sliding tube 4, so that the interior of the sliding tube 4 always has sufficient 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 piece 212 to slide together, so that new lubricating oil can be added to the lubricating oil tank 25. Through this design, the lubricating oil in the lubricating oil tank 25 can be replenished;

[0046] The design of the sealing block 29 allows the subsequent sliding tube 4 to drive the oil outlet pipe 210 to slide up and down, and can drive the sealing block 29 to slide in the first slide groove 28 through the oil outlet pipe 210. At the same time, the diameter of the oil outlet hole 27 is much larger than the circular hole 214. Through this design, even when the sealing block 29 slides in the first slide groove 28, the circular hole 214 can always be connected to the oil outlet hole 27, so that the lubricating oil in the lubricating oil tank 25 can be continuously transported into 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, and the sealing block 29 will not be separated from the first slide groove 28. Through this design, the sealing block 29 can also always block the oil outlet hole 27 to prevent the lubricating oil from leaking out through the oil outlet hole 27.

[0047] When the rocker arm 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 wave, 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, the design of the hose 211 ensures that 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 will block one end of the sliding tube 4 under the action of the third spring 42 to prevent the lubricating oil from leaking. Through such a design, the coating sealing ball 41 can be coated with lubricating oil on the side wall of the mounting slide rail 1 when sliding on the side wall of the mounting slide rail 1. Such a design can save lubricating oil to a certain extent and can complete the lubrication of 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, the sliding shell 2 slides and drives the spreading plate 21 to spread the coated lubricating oil, so that the lubricating oil can be evenly applied to the side wall of the mounting slide rail 1.

[0048] When the swing lever 36 drives the sliding tube 4 and the control lever 45 and the sliding ball 46 on the sliding tube 4 to slide to the depth wave slide groove 242, through the design of the wave fluctuation of the depth wave slide groove 242, the sliding ball 46 is guided to slide along the up-and-down fluctuation path of the depth wave slide groove 242, so that the sliding ball 46 drives the sliding tube 4 to slide up and down at one end of the swing lever 36 through the control lever 45. Through such design, the point sealing ball 41 can increase the area of the side wall of the installation slide rail 1, so that the lubricating oil can be evenly applied to the side wall of the installation slide rail 1. When the sliding tube 4 slides up and down at one end of the swing lever 36, the sliding tube 4 can extrude the clamping plates 39 on both sides, so that the clamping plates 39 slide through the second slide groove 37. Through the design of the second slide groove 37, the clamping plates 39 will not deviate during sliding, and can also prevent the clamping plates 39 from sliding out of the predetermined track, so that the clamping plates 39 can slide more stably. When the clamping plates 39 slide, the second spring 38 on one side of the clamping plates 39 can be deformed. Through such design, the sliding tube 4 can be clamped in the middle by the two clamping plates 39, which can provide certain assistance when the sliding tube 4 returns to the original position. Through the clamping of the clamping plates 39 on the sliding tube 4, the sliding tube 4 will not be tilted, so that the point sealing ball 41 on the sliding tube 4 can always be perpendicular to the installation slide rail 1 for point application;

[0049] Through the combined design of the transverse wave slide groove 241 and the depth wave slide groove 242, when the sliding ball 46 slides in the transverse wave slide groove 241 and the depth wave slide groove 242, the point sealing ball 41 can increase the contact area with the side wall of the installation slide rail 1, and can also point the side wall of the installation slide rail 1. Increasing the contact area can also reduce the loss of lubricating oil. By applying lubricating oil to the inner side wall of the installation slide rail 1, the electric meter 5 can slide more smoothly when installed on the installation slide rail 1, without jamming. It can also prevent the inner side of the installation slide rail 1 from rusting.

[0050] After lubricating the side wall of the installation 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 reverse rotation of the rotating wheel 3, one end of the pawl 31 does not resist the teeth of the ratchet wheel 34, so that the rotating wheel 3 does not rotate the rotating column 35 while reversing. Through such design, when the sliding shell 2 is slid back, the side wall of the installation slide rail 1 will not be point applied again.
