[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide an oil filling device that solves the problem that the main principle of the existing filling equipment is to fill by piston injection. Before filling, the oil needs to be drawn into the filling pipe first, and then filling can be carried out. The filling process is long and affects the work efficiency.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An oil filling device includes a housing, a pair of fixing rods fixedly connected to the back of the housing, a filling pipe body fixedly connected to one end of each pair of fixing rods, a one-way discharge valve port fixedly connected to the lower end of the filling pipe body, a one-way inlet valve port fixedly connected to the outer circumferential surface of the filling pipe body, and an inlet pipe fixedly connected to one end of the one-way inlet valve port.

[0010] Gear 1 and Gear 2 are rotatably connected inside the housing. Pulley 1 is fixedly connected to one side of Gear 2, and Pulley 2 is rotatably connected inside the housing. Pulley 1 and Pulley 2 are connected by a belt. A threaded screw is fixedly connected to one side of both Gear 1 and Pulley 2. An internal threaded ring is threaded onto the outer circumference of the threaded screw. A connecting rod is fixedly connected to one side of the internal threaded ring. A piston is fixedly connected to one end of the connecting rod. A limit ring is fixedly connected to the outer circumference of the internal threaded ring. A guide rod passes through the limit ring and is fixed to the lower end of the housing. A motor is fixedly connected to the upper end of the housing, and the output shaft of the motor is connected to Gear 1.

[0011] Furthermore, one of the internal threaded rings is located at the upper end of the threaded screw, and the other internal threaded ring is located at the lower end of the threaded screw.

[0012] Furthermore, the threaded screw is positioned outside the filling tube body.

[0013] Furthermore, a rubber layer is provided on the outer circumferential surface of the piston, and it is in close contact with the inner wall of the filling tube body.

[0014] 3. Beneficial Effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) This scheme is equipped with two filling tube bodies, each of which is equipped with a piston injection unit. The difference is that the piston block of the piston injection unit in one filling tube body is located at the upper end of the filling tube body, while the piston block of the piston injection unit in the other filling tube body is located at the lower end of the filling tube body. When one filling tube body is filling, the other filling tube body has already completed the extraction. This cycle is repeated, and there is no need to wait for the extraction process, which can effectively improve work efficiency.

[0017] (2) After the motor is started, the motor will drive gear one to rotate. Since gear one and gear two mesh, gear two rotates in the opposite direction to gear one. Then, under the transmission of pulley one and belt, pulley two and gear two maintain the same rotation direction, but the opposite rotation direction to gear one. Therefore, when the threaded screw at the lower end of gear one drives the piston block to move upward, the threaded screw at the lower end of pulley two will drive the piston block to move downward, thereby realizing the simultaneous extraction and filling of the two filling tube bodies, and sharing the same drive unit, which can effectively save costs.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example

[0026] like Figure 1-4 As shown, an oil filling device includes a housing 1. A pair of fixing rods 2 are fixedly connected to the back of the housing 1. A filling pipe body 3 is fixedly connected to one end of each pair of fixing rods 2. A one-way discharge valve port 4 is fixedly connected to the lower end of the filling pipe body 3. A one-way feed valve port 5 is fixedly connected to the outer circumferential surface of the filling pipe body 3. A feed pipe 6 is fixedly connected to one end of the one-way feed valve port 5.

[0027] Gear 7 and gear 8 are rotatably connected inside housing 1. Pulley 9 is fixedly connected to one side of gear 8. Pulley 10 is rotatably connected inside housing 1. Pulley 9 and pulley 10 are connected by a belt strip 11. Threaded screws 12 are fixedly connected to one side of both gear 7 and pulley 10. An internal threaded ring 13 is threadedly connected to the outer circumference of the threaded screw 12. A connecting rod 14 is fixedly connected to one side of the internal threaded ring 13. A piston 15 is fixedly connected to one end of the connecting rod 14. A limit ring 16 is fixedly connected to the outer circumference of the internal threaded ring 13. A guide rod 17 passes through the limit ring 16. The guide rod 17 is fixed to the lower end of housing 1. A motor 18 is fixedly connected to the upper end of housing 1. The output shaft of the motor 18 is connected to gear 7.

[0028] One internal threaded ring 13 is located at the upper end of the threaded screw 12, and the other internal threaded ring 13 is located at the lower end of the threaded screw 12.

[0029] In use, after starting the motor 18, the motor 18 will drive the gear 7 to rotate. Since the gear 7 and the gear 8 are meshed, the gear 8 rotates in the opposite direction to the gear 7. Then, under the transmission of the pulley 9 and the belt 11, the pulley 10 and the gear 8 maintain the same rotation direction, but the opposite rotation direction to the gear 7. Therefore, when the threaded screw 12 at the lower end of the gear 7 drives the piston block 15 to move upward, the threaded screw 12 at the lower end of the pulley 10 will drive the piston block 15 to move downward, thereby realizing the simultaneous extraction and filling of the two filling tube bodies 3, and sharing the same drive unit, which can effectively save costs.

[0030] like Figure 3 As shown, the threaded screw 12 is placed outside the filling tube body 3.

[0031] When in use, compared to existing filling devices, the threaded screw 12 does not occupy the internal space of the filling tube body 3, and can accommodate more oil products, thus enabling large-capacity filling.

[0032] like Figure 3 As shown, a rubber layer is provided on the outer circumferential surface of the piston 15, and it is in close contact with the inner wall of the filling tube body 3.

[0033] When in use, it can effectively improve the sealing between the piston 15 and the filling tube body 3.

[0034] In summary, the specific working process of this solution is as follows: This utility model is equipped with two filling tube bodies 3, each of which is equipped with a piston injection unit. The difference is that the piston block 15 of the piston injection unit in one filling tube body 3 is located at the upper end of the filling tube body 3, while the piston block 15 of the piston injection unit in the other filling tube body 3 is located at the lower end of the filling tube body 3. When one filling tube body 3 is filling, the other filling tube body 3 has already completed the extraction. This cycle continues, eliminating the need to wait for the extraction process and effectively improving work efficiency.

[0035] When the motor 18 is started, it drives gear 7 to rotate. Since gear 7 and gear 8 mesh, gear 8 rotates in the opposite direction to gear 7. Then, under the transmission of pulley 9 and belt 11, pulley 10 rotates in the same direction as gear 8, but in the opposite direction to gear 7. Therefore, when the threaded screw 12 at the lower end of gear 7 drives the piston block 15 to move upward, the threaded screw 12 at the lower end of pulley 10 will drive the piston block 15 to move downward, thereby realizing the simultaneous extraction and filling of the two filling tube bodies 3, and sharing the same drive unit, which can effectively save costs.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
