Abstract
Description
Technical Field
[0001] This utility model relates to the field of grease nipple technology, and specifically to a novel grease nipple. Background Technology
[0002] An excavator is a heavy-duty construction machine primarily used for digging, loading, and transporting materials. It uses a bucket to excavate materials above or below the machine's surface, then loads the material into transport vehicles or unloads it into a stockpile. Materials that excavators can handle include soil, coal, silt, and pre-loosened rock and ore.
[0003] The working device of an excavator is one of its most important components, mainly consisting of the boom, stick, and bucket. The length and thickness of the boom and stick determine the excavator's working range and digging depth, while the size of the bucket determines its loading capacity. The excavator's boom is connected by multiple rotating rods, which require lubrication at the boom joints for durability. However, traditional boom lubrication involves applying grease to the boom joints and rod supports. This grease is consumed over time, leading to wear and tear on the boom joints and rods, requiring repeated application. This method is time-consuming, labor-intensive, and prone to wasting materials and causing damage. Another method involves injecting grease using grease nipples, but these nipples have flat tops while the ball bearings protrude from the flat surface. Using a pointed grease gun makes it difficult to align and insert the nozzle into the grease inlet near the nipple, resulting in wasted lubricant.
[0004] Therefore, the existing grease nipple technology needs further design. Summary of the Invention
[0005] The purpose of this invention is to overcome the problems of existing grease nipples, such as difficulty in aligning the nozzle tip with the grease inlet, time and effort consumption, and waste of lubricating grease. By rationally designing the grease nipple technology and using a threaded seat, auxiliary rotating head, grease passage cavity, groove, spring, and nozzle plug, it is possible to easily and quickly insert the pointed nozzle tip into the grease passage cavity, saving time and effort, and also saving lubricating grease.
[0006] The specific technical solution of this utility model is as follows: A novel grease nipple includes: a threaded seat, an auxiliary rotating head, a grease passage cavity, a groove, a spring, and a plug. The auxiliary rotating head is mounted on one end of the threaded seat. The grease passage cavity is provided inside both the threaded seat and the auxiliary rotating head. The groove is provided on the top of the auxiliary rotating head. The grease passage cavity and the groove are interconnected. One end of the spring is mounted on the cavity wall of the grease passage cavity, and the plug is mounted on the other end of the spring. The plug is disposed inside the grease passage cavity and is used to close or open the opening at the connection between the groove and the grease passage cavity.

[0012] Furthermore, the threaded seat and the auxiliary rotating head are integrally formed.
[0013] Furthermore, the auxiliary rotating head includes a rotating head, a connector, and an auxiliary nozzle. The rotating head is mounted on one end of the threaded seat, the connector is mounted on the rotating head, and the auxiliary nozzle is mounted on the connector. The rotating head, the connector, and the auxiliary nozzle are all provided with an oil passage cavity inside. The groove is provided on the top of the auxiliary nozzle. The oil passage cavity and the groove are interconnected. The spring and the nozzle plug are both disposed in the oil passage cavity of the auxiliary nozzle.
[0014] Furthermore, the included angle between the central axis of the rotating head and the central axis of the auxiliary nozzle is selected to be 70° to 180°.
[0015] Furthermore, the angle between the central axis of the rotating head and the central axis of the auxiliary nozzle is preferably 90° to 180°; when the angle between the central axis of the rotating head and the central axis of the auxiliary nozzle is 90°, the rotating head and the auxiliary nozzle are perpendicular to each other; when the angle between the central axis of the rotating head and the central axis of the auxiliary nozzle is 90° to 180°, but the angle is not located at the two endpoints, the rotating head and the auxiliary nozzle form an obtuse angle to each other; when the angle between the central axis of the rotating head and the central axis of the auxiliary nozzle is 180°, the rotating head and the auxiliary nozzle are arranged in a straight line.
[0016] Furthermore, the groove is selected as a V-shaped groove or an arc-shaped groove.
[0017] Furthermore, the angle of the V-shaped groove is selected from 30° to 150°.
[0018] Furthermore, the angle of the V-shaped groove is preferably 90°.

The threaded seat 01 is equipped with an auxiliary rotating head 02 at one end. Both the threaded seat 01 and the auxiliary rotating head 02 are provided with oil passage chambers. The auxiliary rotating head 02 is provided with a groove 03 at the top. The oil passage chamber and the groove 03 are interconnected. One end of the spring 05 is installed on the cavity wall of the oil passage chamber. The other end of the spring 05 is equipped with a plug 04. The plug 04 is located in the oil passage chamber and is used to close or open the opening at the connection between the groove 03 and the oil passage chamber. See Figures 1-3As shown, an auxiliary rotating head 02 is installed on one end of the threaded seat 01. That is, a metal tube is selected, and an external thread is cut into one end of the metal tube to serve as the threaded seat 01. Then, a hexagonal auxiliary rotating head is cut and milled at the other end of the metal tube (that is, above the threaded seat 01). A V-shaped groove, that is, a frustum groove, is drilled and milled on the top of the hexagonal auxiliary rotating head. Then, an oil passage cavity is drilled into the inner wall of the metal tube. The diameter of the oil passage cavity is larger than the small circle diameter of the frustum groove. Then, a spherical plug (that is, a ball bearing) is connected to one end of the spring, and the two are placed in the oil passage cavity. The other end of the spring is welded to the end of the threaded seat to form a spring stop 06, thus producing the grease nipple.
[0036] See Figures 4-9 As shown, the auxiliary rotating head 02 includes a rotating head, a connector 07, and an auxiliary nozzle 08. The rotating head is mounted on one end of the threaded seat 01, the connector 07 is mounted on the rotating head, and the auxiliary nozzle 08 is mounted on the connector 07. Each of the rotating head, connector 07, and auxiliary nozzle 08 has an oil passage cavity.

A spring 05 and a nozzle plug 04 are both located within the oil passage cavity of the auxiliary nozzle 08. The threaded seat 01, rotating head, and connector 07 are all integrally formed. A clearance groove 09 is provided on the outer side of the auxiliary nozzle 08, which is used to allow for and engage external objects. Here, the threaded seat 01, rotating head, and connector 07 are all integrally formed, and the rotating head is a hexagonal rotating head; that is: [The text abruptly ends here, likely due to an incomplete translation or source material.] Take a metal tube and thread an external thread into one end of the metal tube to form a thread seat 01. Then, cut and mill a hexagonal rotating head at the other end of the metal tube (that is, above the thread seat 01). Mill a connector on the upper part of the hexagonal rotating head. Select another metal tube and drill and mill a V-shaped groove, that is, a frustum groove, on one end. Then, drill an oil passage cavity on the inner wall of the metal tube. The diameter of the oil passage cavity is larger than the small circle diameter of the frustum groove. Then, connect a spherical plug (that is, a ball bearing) to one end of a spring and put both into the oil passage cavity. Weld the other end of the spring to the other end of the other metal tube to form a spring stop 06. Make the auxiliary nozzle 08. Then, weld the auxiliary nozzle 08 to the connector 07 to make the grease nipple.

Specifically, see Figures 7-9 As shown, when the angle between the central axis of the rotating head and the central axis of the auxiliary nozzle 08 is 90° to 180°, but the angle is not located at the two endpoints, the rotating head and the auxiliary nozzle 08 present an obtuse angle to each other.
[0038] The specific implementation method of this utility model is as follows: The prepared grease nipple is connected to the external mechanical part that needs to be greased by thread. The grease nipple is tightened or loosened by a hexagonal auxiliary rotating head. Then, a pointed grease gun head is selected, and the grease gun head is inserted into the groove and the opening of the oil passage by hand. The grease gun head will push the nozzle plug away, and the lubricating grease can be injected. Due to the inclined surface of the groove, it is easy to align the grease gun head with the hand and insert it into the opening for grease injection.
[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.
