[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] First embodiment: See Figures 1-3 As shown, this utility model provides a lubricating oil filling device, including an electric telescopic rod 1. The top of the electric telescopic rod 1 is fixedly installed on the lubricating oil conveying equipment. A filling cylinder 2 is fixedly connected to the telescopic end of the electric telescopic rod 1. The capacity of the filling cylinder 2 is 1L-3L. The filling cylinder 2 can be connected to a fixed block through a hose clamp. The fixed block is fixedly connected to the output end of the electric telescopic rod 1. The high end of the filling cylinder 2 is provided with a feed pipe 201 and an air pipe 202. Both the feed pipe 201 and the air pipe 202 are connected and installed at the high end of the filling cylinder 2. The outer end of the feed pipe 201 is connected to the output end of the oil supply pump. The outer end of the air pipe 202 is connected to a filter frame 3. The bottom of the filling cylinder 2 is open and is equipped with a sealing frame 5. A flange is welded to the high end of the sealing frame 5. The bottom of the filling cylinder 2 is equipped with a flange corresponding to the flange. A sealing ring is provided between the two flanges. The two flanges are fixed by bolts. A vertical rod 6 is slidably connected inside the sealing frame 5. The inner end of the vertical rod 6 extends into the filling cylinder 2 and is connected to a sealing block 601. The outer end of the vertical rod 6 extends out of the sealing frame 5. The side wall of the vertical rod 6 is provided with an oil outlet hole 602 extending to its bottom end. A thrust spring 7 is provided on the outer side of the vertical rod 6 to push the vertical rod 6 to slide downward. The thrust spring 7 can push the vertical rod 6 to move downward, so that the bottom end of the vertical rod 6 can extend into the lubricating oil tank to assist in the delivery of lubricating oil. When the device is in use, the electric telescopic rod 1 supports the filling cylinder 2. When dispensing and filling lubricating oil, the oil supply pump guides the lubricating oil into the filling cylinder 2 through the feed pipe 201. As the amount of oil inside the filling cylinder 2 changes, the filter frame 3 can be used to assist in the adjustment of the air pressure inside the filling cylinder 2. When the oil tank is aligned with the upright rod 6, the bottom end of the upright rod 6 is aligned with the mouth of the oil tank. After the electric telescopic rod 1 extends, the filling cylinder 2 moves downward, and the sealing frame 5 slides relative to the upright rod 6. Then, the high-end sealing block 601 of the upright rod 6 extends into the filling cylinder 2, releasing the seal of the sealing block 601. The lubricating oil is then guided downward through the oil outlet hole 602 on the upright rod 6 to the inside of the oil tank, realizing the filling and delivery of lubricating oil.

[0020] The second embodiment differs from the first embodiment in that: The filter frame 3 includes an air valve 301 connected to the air pipe 202. The air valve 301 has a filter layer 302 on its outer side. In the structure of the filter frame 3, the air valve 301 can assist in the delivery of gas inside the filling cylinder 2 and, together with the filter layer 302, filter the introduced and entered gas. Furthermore, the air valve 301 is threadedly connected to the air pipe 202. The connection between the filter frame 3 and the air pipe 202 is achieved by the threaded connection between the air valve 301 and the air pipe 202.

[0021] The third embodiment differs from the first embodiment in that: The sealing frame 5 has a guide groove 501 inside, which is vertically arranged. The upright 6 slides with the guide groove 501, and the guide groove 501 guides the upright 6. The top surface of the guide groove 501 has a conical surface that extends to the inner wall of the filling cylinder 2. The bottom surface of the sealing block 601 seals with the conical surface. After the upright 6 slides downward, the sealing block 601 seals the conical surface, which can prevent the lubricating oil from being discharged. In the preferred embodiment, the oil outlet 602 is Y-shaped. Its high end hole aligns with the side wall of the guide groove 501. After the upright 6 slides upward, the upper end of the oil outlet 602 enters the filling cylinder 2. The oil outlet 602 can assist in the delivery of lubricating oil, allowing the lubricating oil to be delivered downward along the oil outlet 602 and into the oil tank.

[0022] In addition, a baffle 603 is provided on the outside of the upright 6. The thrust spring 7 is located between the sealing frame 5 and the baffle 603. The baffle 603 is close to the bottom end of the upright 6, forming a support for the thrust spring 7. When the baffle 603 corresponds to the filling tank, the baffle 603 contacts the bottle mouth of the filling tank. As the electric telescopic rod 1 extends, the filling cylinder 2 moves downward, and the thrust spring 7 is compressed. The relative position of the upright 6 and the filling cylinder 2 slides upward. In the preferred structure of the baffle 603, the baffle 603 is conical, and the large end of the conical surface faces upward. With the contact between the baffle 603 and the bottle mouth of the filling tank, the bottom end of the upright 6 can be correspondingly set with the bottle mouth of the filling tank.

[0023] The fourth embodiment differs from the first embodiment in that: The filling cylinder 2 is equipped with a liquid sensor 4 and a microcontroller. The liquid sensor 4, the electric telescopic rod 1, and the oil supply pump are all electrically connected to the microcontroller. The liquid sensor 4 can monitor the liquid flow rate inside the filling cylinder 2. The microcontroller can receive the liquid volume inside the filling cylinder 2. When the liquid inside the filling cylinder 2 is low, the microcontroller controls the corresponding oil supply pump to supply oil into the filling cylinder 2. When the liquid inside the filling cylinder 2 is high, the microcontroller controls the corresponding supply pump to stop supplying oil into the filling cylinder 2.
