Description

Technical Field

[0001] This utility model relates to the field of emulsified oil filling technology, specifically to a low-loss, leak-proof emulsified oil filling mechanism. Background Technology

[0002] Emulsified oil is a widely used lubricating and cooling medium in industrial fields. In industries such as machining and metal processing, emulsified oil can effectively reduce friction and heat generation during processing, improving processing efficiency and quality. By forming a protective film on the processed surface, emulsified oil reduces direct contact between the tool and the workpiece, thereby reducing wear, extending tool life, and carrying away heat generated during processing, maintaining a stable processing environment.

[0003] Traditional emulsified oil filling processes typically involve simple pouring or using a regular pump. This method is prone to causing emulsified oil splashing and leakage during operation. For example, when pouring emulsified oil, improper operation or container instability can cause it to splash out of the container, wasting the oil and potentially contaminating the working environment.

[0004] After filling, due to the lack of proper leak-proof measures, the emulsified oil remaining inside the pipes and equipment will gradually leak out. This leakage not only wastes the emulsified oil but may also make the ground around the equipment slippery, increasing the risk of operators slipping and falling.

[0005] Therefore, a low-loss, leak-proof emulsified oil filling mechanism is needed to improve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a low-loss, leak-proof emulsified oil filling mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A low-loss, leak-proof emulsified oil filling mechanism includes a threaded cap, with an oil inlet hose fixedly installed at the lower end of the threaded cap. The upper end of the oil inlet hose is connected to a hand-cranked oil pumping mechanism via the oil inlet hose. The hand-cranked oil pumping mechanism is connected to the inlet of the cylindrical hollow shell of the leak-proof mechanism via a connecting pipe.

[0009] As a preferred embodiment of this utility model, the hand-cranked oil pumping mechanism includes: a circular hollow oil pump housing, an eccentrically rotating rotor inside the circular hollow oil pump housing, an inner sliding groove extending horizontally through the center of the rotor, and a movable partition plate sliding inside the inner sliding groove.

[0010] As a preferred embodiment of this utility model, the rotor is fitted to the inner wall of the circular hollow oil pump housing, and the inside of the circular hollow oil pump housing is provided with an oil inlet hole and an oil outlet hole respectively corresponding to the rotor above and below. The oil inlet hole and the oil outlet hole are fixedly connected to connecting pipe one and connecting pipe two respectively, and the outer diameter of the movable partition plate is the same as the inner diameter of the circular hollow oil pump housing.

[0011] As a preferred embodiment of this utility model, a crank handle is rotatably provided on one side of the circular hollow oil pump housing, and one end of the crank handle passes through the circular hollow oil pump housing and is fixed to the center of the rotor.

[0012] As a preferred embodiment of this utility model, the leak-proof mechanism includes a cylindrical hollow shell, a spring fixedly installed at the lower end of the cylindrical hollow shell, a connecting rod installed inside the spring, and a sealing ball and a sealing cover plate respectively installed at both ends of the connecting rod.

[0013] As a preferred embodiment of this utility model, an oil drain head is fixedly provided at the lower end of the cylindrical hollow shell, the inlet at the upper end of the cylindrical hollow shell is fitted and connected to the sealing ball, and the outlet on the lower side inside the oil drain head is fitted and connected to the sealing cover plate.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A low-loss, leak-proof emulsified oil filling mechanism includes a threaded cap 2, with an oil inlet hose 1 fixedly installed at the lower end of the threaded cap 2. The upper end of the oil inlet hose 1 is connected to a hand-cranked oil pumping mechanism 4 through the oil inlet hose 1. The hand-cranked oil pumping mechanism 4 is connected to the inlet of the cylindrical hollow shell 19 of the leak-proof mechanism 7 through a connecting pipe 2 6.

[0028] As an example of this utility model, the hand-cranked oil pumping mechanism 4 includes: a circular hollow oil pump housing 18, a rotor 12 eccentrically rotated inside the circular hollow oil pump housing 18, an inner groove 9 transversely extending through the center of the rotor 12, and a movable partition plate 11 slidably disposed inside the inner groove 9. When the user turns the crank handle 5, the crank handle 5 drives the rotor 12 to rotate eccentrically inside the circular hollow oil pump housing 18. Since the inner groove 9 transversely extending through the center of the rotor 12, and the movable partition plate 11 slidably disposed inside the inner groove 9, and the outer diameter of the movable partition plate 11 is the same as the inner diameter of the circular hollow oil pump housing 18, the movable partition plate 11 will slide in the inner groove 9 as the rotor 12 rotates, thereby changing the internal spatial volume of the circular hollow oil pump housing 18.

[0029] As an example of this utility model, the rotor 12 is fitted to the inner wall of the circular hollow oil pump housing 18, and the circular hollow oil pump housing 18 is provided with an oil inlet hole 8 and an oil outlet hole 10 respectively corresponding to the upper and lower parts of the rotor 12. The oil inlet hole 8 and the oil outlet hole 10 are fixedly connected to the connecting pipe 3 and the connecting pipe 6 respectively. The outer diameter of the movable partition plate 11 is the same as the inner diameter of the circular hollow oil pump housing 18. When the rotor 12 rotates and the movable partition plate 11 approaches the oil inlet hole 8, the space volume on the side of the circular hollow oil pump housing 18 near the oil inlet hole 8 increases, forming a negative pressure. At this time, the emulsified oil will be sucked into the circular hollow oil pump housing 18 from the outside through the oil inlet hose 1 and the connecting pipe 3.

[0030] As an example of this utility model, a crank handle 5 is rotatably provided on one side of the circular hollow oil pump housing 18. One end of the crank handle 5 passes through the circular hollow oil pump housing 18 and is fixed to the center of the rotor 12. As the rotor 12 continues to rotate, the movable partition plate 11 moves away from the oil inlet hole 8 and moves closer to the oil outlet hole 10. The volume of the space inside the circular hollow oil pump housing 18 near the oil outlet hole 10 decreases, the emulsified oil is squeezed, and is drawn out through the oil outlet hole 10 and the connecting pipe 6, and enters the cylindrical hollow housing 19 of the leak-proof mechanism 7.

[0031] As an example of this utility model, the leak-proof mechanism 7 includes a cylindrical hollow shell 19. A spring 14 is fixedly installed at the lower end of the cylindrical hollow shell 19. A connecting rod 15 is installed inside the spring 14. Sealing balls 13 and sealing covers 16 are respectively installed at both ends of the connecting rod 15. After the emulsified oil is drawn out from the hand-cranked oil extraction mechanism 4 into the cylindrical hollow shell 19, the leak-proof mechanism 7, because the lower end of the cylindrical hollow shell 19 is fixedly installed with the spring 14, and the connecting rod 15 is installed inside the spring 14, with sealing balls 13 and sealing covers 16 respectively installed at both ends of the connecting rod 15, ensures that the leak-proof mechanism 7 can prevent leakage. 3 and sealing cover 16, and the inlet at the upper end of the cylindrical hollow shell 19 is fitted and connected to the sealing ball 13, and the outlet on the lower side of the oil drain head 17 is fitted and connected to the sealing cover 16. Under the pressure of the emulsified oil, the sealing ball 13 and sealing cover 16 will be pushed downward, so that the emulsified oil can pass smoothly through the gap between the sealing ball 13 and the upper end inlet of the cylindrical hollow shell 19, flow downward along the connecting rod 15, and finally be discharged through the outlet on the lower side of the oil drain head 17, thus completing the filling of emulsified oil.

[0032] As an example of this utility model, a drain head 17 is fixedly provided at the lower end of the cylindrical hollow shell 19. The inlet at the upper end of the cylindrical hollow shell 19 is fitted and connected to the sealing ball 13. The outlet on the lower side inside the drain head 17 is fitted and connected to the sealing cover plate 16. When the filling mechanism stops working and the emulsified oil is no longer extracted, the pressure inside the cylindrical hollow shell 19 decreases. At this time, the spring 14 will push the connecting rod 15 to move upward due to its own elastic restoring force, so that the sealing ball 13 will be tightly fitted again to the inlet at the upper end of the cylindrical hollow shell 19. At the same time, the sealing cover plate 16 will also be tightly fitted to the outlet on the lower side inside the drain head 17, completely sealing the channel inside the cylindrical hollow shell 19 and preventing the emulsified oil from leaking.

[0033] Working principle: When using,

[0034] When the user turns the crank handle 5, the crank handle 5 drives the rotor 12 to rotate eccentrically inside the circular hollow oil pump housing 18. Since the rotor 12 has an inner groove 9 that runs through the center laterally, and a movable partition plate 11 is slidably installed inside the inner groove 9, and the outer diameter of the movable partition plate 11 is the same as the inner diameter of the circular hollow oil pump housing 18, the movable partition plate 11 will slide in the inner groove 9 as the rotor 12 rotates, thereby changing the internal space volume of the circular hollow oil pump housing 18.

[0035] When the rotor 12 rotates and the movable partition plate 11 approaches the oil inlet 8, the volume of the space inside the circular hollow oil pump housing 18 near the oil inlet 8 increases, forming a negative pressure. At this time, the emulsified oil will be sucked into the circular hollow oil pump housing 18 from the outside through the oil inlet hose 1 and the connecting pipe 3.

[0036] As the rotor 12 continues to rotate, the movable partition plate 11 moves away from the oil inlet 8 and closer to the oil outlet 10. The volume of the space inside the circular hollow oil pump housing 18 near the oil outlet 10 decreases, the emulsified oil is squeezed out through the oil outlet 10 and the connecting pipe 6, and enters the cylindrical hollow housing 19 of the leak-proof mechanism 7.

[0037] After the emulsified oil is drawn from the hand-cranked oil extraction mechanism 4 into the cylindrical hollow shell 19, a spring 14 is fixedly installed at the lower end of the cylindrical hollow shell 19. A connecting rod 15 is installed inside the spring 14. A sealing ball 13 and a sealing cover plate 16 are respectively installed at both ends of the connecting rod 15. The inlet at the upper end of the cylindrical hollow shell 19 is in close contact with the sealing ball 13, and the outlet at the lower side of the oil discharge head 17 is in close contact with the sealing cover plate 16. Under the pressure of the emulsified oil, the sealing ball 13 and the sealing cover plate 16 will be pushed downward, so that the emulsified oil can pass smoothly through the gap between the sealing ball 13 and the inlet at the upper end of the cylindrical hollow shell 19, flow downward along the connecting rod 15, and finally be discharged through the outlet at the lower side of the oil discharge head 17, thus completing the filling of the emulsified oil.

[0038] When the filling mechanism stops working and the emulsified oil is no longer extracted, the pressure inside the cylindrical hollow housing 19 decreases. At this time, due to its own elastic restoring force, the spring 14 will push the connecting rod 15 to move upward, so that the sealing ball 13 will once again fit tightly against the inlet at the upper end of the cylindrical hollow housing 19. At the same time, the sealing cover plate 16 will also fit tightly against the outlet on the lower side inside the oil drain head 17, completely sealing the channel inside the cylindrical hollow housing 19 and preventing the emulsified oil from leaking.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
