Description

Technical Field

[0001] The invention relates to a funnel for machining equipment, in particular to a refueling funnel. Background Art

[0002] When repairing and maintaining mechanical equipment or before putting new equipment into use, the reducer of the mechanical equipment needs to be filled with lubricating oil through the refueling port. Since the refueling port of a small reducer is generally small, a refueling funnel is usually used during the refueling process.

[0003] The refueling funnel is usually composed of an upper oil storage section composed of a larger cylindrical section and a truncated cone section and a guide section composed of a smaller truncated cone. When filling the lubricating oil, the guide section of the refueling funnel is inserted into the refueling port of the reducer, and the lubricating oil is poured into the oil storage section of the refueling funnel, and the lubricating oil flows into the reducer by its own weight. However, this type of refueling funnel has the following problems when refueling: since the refueling port of the reducer and the exhaust port during operation are usually designed to be the same hole, and in order to facilitate the installation of the exhaust cock, the refueling port is usually designed to be circular, and there is no additional exhaust hole; when using the funnel to refuel, the truncated cone of the funnel forms a good fit with the circular hole of the refueling port. When the lubricating oil flows into the reducer, the air in the original space of the reducer has no other exhaust port to discharge, and the large air pressure inside the reducer hinders the injection of the lubricating oil, and the refueling action cannot be continuous, which prolongs the refueling time. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a refueling funnel capable of improving the refueling speed.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] A refueling funnel is composed of an oil storage section with a cylindrical structure and a guide section with a conical structure; the guide section is arranged at the bottom center of the oil storage section, and a guide hole connected up and down is arranged at the center of its end, the guide hole is in a conical structure, and its top is connected up and down with the inner cavity of the oil storage section, a first guide body protruding outward is arranged on the outer side of the guide section along its height direction, and the position corresponding to the first guide body on the inner wall surface of the guide hole is concave to form a lower guide groove.

[0007] Furthermore, a second guide body protruding downward is provided at the bottom of the oil storage section along its radial direction, and the bottom surface of the inner cavity of the oil storage section corresponding to the second guide body is concave to form an upper guide groove, and the upper guide groove is connected to the lower guide groove.

[0008] Furthermore, the inner wall surface of the guide hole is provided with a pressure relief strip protruding toward its center line along its height direction, and the pressure relief strip is integrally formed with the guide section, and the outer surface of the guide section corresponding to the pressure relief strip is concave to form a pressure relief groove, and the bottom of the pressure relief groove passes through the bottom of the guide section.

[0009] Furthermore, the top of the pressure relief groove extends along the radial direction of the bottom surface of the oil storage section.

[0010] Furthermore, a spacing bar fixedly connected to the guide section is arranged on the outer side of the guide section along its height direction.

[0011] Compared with the prior art, the advantage of the present invention lies in that: the refueling funnel is provided with a protruding spacer strip or a guide body on the outer wall surface of the guide section, or is provided with a concave pressure relief groove on its outer side surface, which can form a gap between the guide section and the refueling port, thereby facilitating the discharge of air inside the equipment's refueling bin, and is not blocked by pressure during refueling, thereby ensuring smooth refueling and thereby increasing the refueling speed.
