Problems solved by technology

However, after the traditional grease nipple is shipped from the factory, the diameter of the internal oil injection channel is fixed, and it does not have the function of oil injection and pressure regulation. The filling pressure can only be adjusted by adjusting the grease gun. However, for long-term field work As far as mechanical equipment is concerned, the commonly used hand-held simple grease guns do not have this function

Embodiment Construction

[0024] like Figure 1-7 As shown, a pressure regulating grease nipple includes a grease nipple body, and the body generally adopts a steel body, such as figure 1 and 2 As shown in the figure, the main body is composed of a hollow head section 1 located at the upper part and a root section 2 located at the lower part. The peripheral surface of the lower part of the root section 2 is provided with an external thread 6, and is rooted in the to-be-to-be-threaded 6 through the external thread 6. For the corresponding parts of the lubricating machine, such as joints, bearings, etc., in order to facilitate the installation of the main body, a screwing head 7 is provided on the peripheral surface of the upper part of the root section 2. Generally, the screwing head 7 adopts an external hexagonal screwing head. Hexagon sockets, etc. can realize quick installation and tightening.

[0025] The top of the head section 1 is provided with an oil filling port 3, and the nozzle of the greas...

Abstract

The invention relates to the technical field of lubrication. The pressure-regulating grease nipple comprises a grease nipple body, the grease nipple body is composed of a hollow head section located on the upper portion and a root section located on the lower portion, an oil filling opening is formed in the top end of the head section, a plugging ball is arranged in the portion, on the inner side of the oil filling opening, of the head section, and the plugging ball is pressed against the oil filling opening through a plugging spring; an external thread is arranged on the circumferential face of the lower portion of the root section, and a screwing head is arranged on the circumferential face of the upper portion of the root section. According to the grease nipple, the grease injection pressure of the grease nipple can be effectively increased, so that the grease nipple has certain unblocking performance, and is particularly suitable for being used on machines for long-term field operation.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to a pressure regulating type grease fitting. Background technique [0002] The grease nipple is also the pressure oil cup, which is installed on the mechanical equipment to be lubricated and used to connect the device between the lubrication part of the mechanical equipment and the grease gun. The grease nipple can be divided into a straight-through pressure oil cup, a joint type pressure oil cup, Screw cap pressure oil cup, etc. The traditional grease nipple generally includes a hollow body, the root end of the body is threaded, and is rooted on the mechanical equipment through the thread, and the head end is blocked by a ball head pressured by a coil spring; The head exerts pressure, and the ball head forms a block on the head end. When the grease needs to be injected, under the injection pressure of the grease gun, the coil spring is compressed, the ball head retreats, and ...
