The invention discloses a pin shaft fixing sleeve with a stable structure, which comprises a pin shaft and a fixing assembly arranged at its end, and the fixing assembly includes a sleeve body arranged at the end of the pin shaft and arranged coaxially therewith. A sealing ring is set on the outer side of the casing, and the sealing ring and the casing are connected by threads. The right end of the sealing ring is provided with a sealing gasket for pressing the surface of the workpiece to isolate the pin shaft installation hole from communicating with the outside world. , use the pin shaft to insert into the connecting hole, and then rotate the sealing ring so that the sealing gasket at the end is in tight contact with the surface of the workpiece. At this time, the pin shaft is isolated from the outside world. The fixing of the pin shaft is realized, and impurities are prevented from entering into the pin shaft hole, which plays a good role in protecting the pin shaft itself, improves the fixing effect of the pin shaft, and has strong practicability.
Description
technical field [0001] The invention relates to the technical field of connection equipment, in particular to a pin shaft fixing sleeve with a stable structure. Background technique [0002] The pin connection is widely used in the mechanical field. There is no uniform design standard for the pin structure. In the actual design of the pin structure, different models and designers have different pin structures, and the use effect is not very good. Ideally, the pin shaft is a kind of standardized fastener, which can be statically fixed or connected relative to the connected parts. It is mainly used at the hinge of two parts to form a hinge connection. The pin shaft is usually locked with a cotter pin. It works reliably and is easy to disassemble. The pin shaft is also one of the necessary accessories inside the car, which can fix the car. [0003] However, the existing pin shaft is easy to shake under the condition of long-time work, causing the pin shaft to fall off, the ser...
