Description

Technical Field

[0001] The utility model relates to the technical field of oil nozzles, in particular to an oil nozzle. Background Art

[0002] A grease nozzle is a part used to add lubricating grease to mechanical equipment. With the valve shaft of the modern manufacturing industry, in order to meet the requirements of precision and service life of today's mechanical equipment, it is necessary to install grease nozzles on the moving parts of mechanical equipment for maintenance personnel to add lubricating grease such as butter to the equipment. At present, the most common shape of grease nozzle is the nipple-type grease nozzle, which has a cylindrical structure at one end and a conical structure at the other end. The conical end is generally used as the oil filling hole, and is sealed by a spring and a ball.

[0003] The prior art includes a utility model with a publication number of CN202867867U, which discloses an oil nozzle. The patent adopts a main body, which is divided into two parts, an upper part and an lower part. A "cross"-shaped short rod is provided inside the first part, a baffle is provided below the short rod, and a spring is provided between the two. The second part is a "T"-shaped structure with an external thread below and a hollow structure in the middle. The utility model has the characteristics of reasonable structural design and convenient use, and solves the problem that some oil nozzles on the market are unreasonable in structural design and inconvenient to use.

[0004] The inventors have discovered in their daily work that in the process of using oil nozzles, there are existing oil nozzles such as the above-mentioned ones whose sealing structures are all arranged inside the main body. When the oil nozzle is used for a long time, the spring structure used for constraint becomes fatigued, causing the oil nozzle sealing to fail. Since the spring is installed inside the oil nozzle, it is difficult to disassemble and replace it separately, so that the oil nozzle with only damaged spring needs to be replaced as a whole, resulting in the problem of increased cost of using the oil nozzle. Utility Model Content

[0025] Specifically, both upper and lower sides of the connection block 63 are chamfered, and there are six connection blocks 63 , which are arranged in a circular array about the connecting ring 62 .

[0026] In this embodiment, by arranging the upper and lower sides of the connection block 63 to be chamfered, the chamfered portion can reduce interference with the grease during the process of filling the grease with the grease nozzle.

[0027] Specifically, there are three connecting rods 65, which are arranged in a circle about the support plate 64. The connecting rods 65 are located on the inner wall of the connecting threaded tube 1. Through the cooperation between the connecting rods 65 and the tripod 66, the support plate 64 can be driven to rotate under the operation of the user.

[0028] In this embodiment: the guide assembly 7 includes a guide column 71, which is slidably connected to the inner wall of the guide hole, an arc tray 72 is fixedly connected to the upper surface of the guide column 71, and a positioning plate 73 is fixedly connected to the lower surface of the guide column 71.
