[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 3 As shown, an oil filling device for an electric switch machine in an embodiment of the utility model comprises a housing 1, wherein lubricating oil is filled in the housing 1, and an oil filling pipe 17 is integrally formed on the bottom wall of the housing 1. A gear box 41 is installed on the electric switch machine 4, and an oil filling hole is provided on the gear box 41. When the internal gear of the gear box 41 needs to be lubricated, the oil filling pipe 17 is inserted into the oil filling hole on the gear box 41 to fill and lubricate the gears of the electric switch machine 4.

[0032] An end cap 11 is sealedly connected to the upper end of the housing 1, and a connecting pipe 12 is integrally formed on the side wall of the housing 1. Specifically, the connecting pipe 12 passes through the side wall of the housing 1, and a ball valve 13 is threadedly connected to one end of the connecting pipe 12 away from the housing 1. The ball valve 13 can close the connecting pipe 12 to achieve the circulation of the connecting pipe 12 and the air outside the housing 1, thereby controlling the speed at which the lubricating oil in the housing 1 flows out of the oil filling pipe 17, and preventing the lubricating oil from flowing out of the oil filling pipe 17 too fast, resulting in the overflow of the lubricating oil.

[0033] The end cover 11 is provided with an external thread 111, and the end cover 11 is threadedly connected to the housing 1 through the external thread 111. A leather sleeve 171 is sleeved on the end of the oil filling pipe 17 away from the housing 1. When the lubricating oil in the housing 1 is used up, the leather sleeve 171 is sealed on the oil filling pipe 17, and the end cover 11 is unscrewed to add lubricating oil to the housing 1.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, in order to prevent the lubricating oil from overflowing from the oil filling hole on the gear box 41 when filling the lubricating oil, causing environmental pollution, four pairs of elastic sheets 16 are bonded to the bottom surface of the housing 1, and an oil suction assembly is clamped between the four pairs of elastic sheets 16, and the oil suction assembly is used to absorb the lubricating oil overflowing from the oil suction port.

[0035] The oil absorption assembly includes a docking ring 3, which is annular and has a connecting block 31 integrally formed on the docking ring 3. A second mounting plate 32 is welded to one end of the connecting block 31 away from the docking ring 3. A first through hole 321 is bonded to the second mounting plate 32, and a second oil absorption sponge 33 is bonded to one side of the first through hole 321 away from the second mounting plate 32. A Velcro 322 is provided on the second mounting plate 32, and a second through hole 331 is provided on the second oil absorption sponge 33. The oil injection pipe 17 penetrates through the first through hole 321 on the second mounting plate 32 and the second through hole 331 on the second oil absorption sponge 33, and is then inserted into the oil injection hole on the electric switch machine 4.

[0036] Specifically, the lower end surface of the second oil-absorbing sponge 33 is flush with the lower end surface of the oil filling tube 17. When the oil filling tube 17 is inserted into the oil filling hole on the gear box 41, the second oil-absorbing sponge 33 is compressed and fits around the oil filling hole on the gear box 41. Since the state of the lubricating oil in the gear box 41 cannot be seen, when the lubricating oil in the gear box 41 is full, the excess lubricating oil will overflow from the oil filling hole, and the overflowed lubricating oil will be absorbed by the second oil-absorbing sponge 33, preventing the lubricating oil from polluting the environment.

[0037] Furthermore, after injecting lubricating oil into the gear box 41, it is also necessary to apply lubricating oil to the lead screw and quick-moving parts in the electric switch machine 4. When applying lubricating oil, press the upper surface of the second mounting plate 32 to disengage the docking ring 3 from between the four pairs of elastic sheets 16, hold the docking ring 3, and use the lubricating oil absorbed by the second oil-absorbing sponge 33 to apply lubricating oil to the lead screw and quick-moving parts in the electric switch machine 4. This not only saves the use of lubricating oil, but also prevents the lubricating oil from sticking to the hands when applying lubricating oil to the lead screw and quick-moving parts. At the same time, there is no need to carry additional tools for applying lubricating oil. The docking ring 3 can be used as a handle, and the second oil-absorbing sponge 33 can be used as an oiling cloth, which makes it more convenient to maintain the parts in the electric switch machine 4.

[0038] It is worth noting that after the second oil-absorbing sponge 33 is used too many times, its oil-absorbing capacity will decrease, and a small amount of lubricating oil may overflow from the second oil-absorbing sponge 33 .

[0039] In order to prevent the lubricating oil on the second oil-absorbing sponge 33 from overflowing, Figures 1 to 5 As shown, four slide rails 14 are integrally formed on the outer wall of the housing 1, and a slider 2 is slidably connected to the slide rails 14. A connecting rod 21 is welded on one side wall of the slider 2 away from the slide rails 14, and the connecting rod 21 is L-shaped. A first mounting plate 22 is welded on one end of the connecting rod 21 away from the slider 2, and a first oil-absorbing sponge 23 is bonded to the lower end surface of the first mounting plate 22.

[0040] Specifically, after the oil filling pipe 17 is inserted into the oil filling hole on the gear box 41, the sliding block 2 is moved so that the lower surface of the first oil absorbing sponge 23 falls on the gear box 41, and the oil filling hole on the gear box 41 and the second oil absorbing sponge 33 are surrounded. The lubricating oil overflowing from the second oil absorbing sponge 33 will be absorbed by the first oil absorbing sponge 23, so that the lubricating oil overflowing from the second oil absorbing sponge 33 can be prevented from flowing to the outside.

[0041] In addition, the first oil-absorbing sponge 23 can increase the contact area with the surface of the gear box 41, so that the housing 1 is firmly on the gear box 41 when oil is injected. When the gear box 41 is injected with oil, it is not necessary to hold the housing 1, and both hands are freed to remove the upper cover of the electric switch machine 4. After the gear box 41 is injected with oil, the lead screw in the electric switch machine 4 can be oiled, which saves working time and improves working efficiency.

[0042] Furthermore, the second oil absorbing sponge 33 is bonded to the second mounting plate 32 through the first through hole 321 , so that when the second oil absorbing sponge 33 is damaged, it is convenient to replace it with a new one.

[0043] like Figure 1 , Figure 3 and Figure 5 As shown, in order to prevent the slider 2 from detaching from the slide rail 14, a first limit block 15 is welded on the side wall of the housing 1, and the lower end surface of the first limit block 15 corresponds to the upper end surface of the first mounting plate 22. A second limit block 211 is bonded to an end surface of the slide rail 14 close to the bottom wall of the housing 1. Specifically, the first limit block 15 limits the first mounting plate 22 to prevent the slider 2 from detaching from the top of the slide rail 14, and 221 limits the slider 2 to prevent the slider 2 from detaching from the bottom of the slide rail 14.

[0044] When in use, turn the ball valve 13 to the closed state, remove the leather cover 171, and insert the leather cover 171 into the oil filling hole on the gear box 41. At this time, the second oil absorption sponge 33 is pressed on the surface of the gear box 41, and the opening of the ball valve 13 is adjusted to control the speed of the lubricating oil flowing out of the housing 1. When the lubricating oil in the gear box 41 is full, close the ball valve 13, take the housing 1 out of the gear box 41, and remove the docking ring 3. After the lubricating oil on the surface of the gear box 41 is absorbed cleanly by the second oil absorption sponge 33, the second oil absorption sponge 33 can also be used to wipe the lead screw, quick-acting parts and other components in the electric switch machine 4.
