As shown in fig. 1-5, a sealed cap nut for a diesel engine includes a cylindrical screw cap portion 11, a cylindrical threaded cavity 111 is formed on the cylindrical screw cap portion 11, and an internal thread is formed on a cavity wall of the cylindrical threaded cavity 111; the threaded connection of the cylindrical screw cap portion 11 into the through bolt on the diesel engine is achieved by means of an internal thread.
The cylindrical screw cap 11 is integrally formed with a cylindrical connecting portion 12, and a hexagonal body portion 121 is integrally formed at an end portion of the cylindrical connecting portion 12; the hexagonal body 121 is designed to facilitate twisting.
In order to realize sealing, a sealing ring component 2 is assembled and connected on the opening of the cylindrical threaded cavity 111.
Specifically, the sealing ring component 2 comprises an annular ring part 21, and a plurality of annularly distributed spherical convex parts 22 are arranged on the annular ring part 21 (the annular ring part 21 and the spherical convex parts 22 are made of rubber); correspondingly, a clamping groove body 23 for clamping and sealing the ring component 2 is arranged on the cavity opening of the cylindrical threaded cavity.
Specifically, the annular ring portion 21 and one half of the volume of the sphere protrusion portion 22 are both limited in the slot body 23. The catch body 23 includes a semi-annular groove portion 231 that mates with the annular ring portion 21; the card slot body 23 further includes a hemispherical groove portion 232 that mates with the body of the ball projection 22.
Therefore, in the structural design, half of the seal ring part 2 is limited in the clamping groove body 23, so that according to the conventional design mode, the clamping groove with the same shape as the clamping groove body 23 is arranged at the top of the engine body of the engine, and the seal ring part 2 is completely clamped and sealed under the matching of the clamping groove body 23 and the clamping groove structure.
The sealing ring component 2 with the structural design is completely clamped and limited by the annular ring part 21-the spherical protruding part 22, so that the sealing ring component 2 is not easy to loosen even under the vibration action in the working process of a diesel engine, the sealing performance is further effectively ensured, and oil leakage is avoided.
In order to avoid the loosening and the unscrewing of the whole part in the vibration process and the oil leakage, the outer side wall of the cylindrical screw cap part 11 is provided with an annular flange 112, and the annular flange 112 is assembled and connected with the locking part 3; the whole assembly is locked by means of the locking member 3.
The specific structure of the locking member 3 is as follows:
the locking component 3 comprises a plurality of locking rods 33 distributed annularly (rod cap bodies are fixedly connected to the left ends of the locking rods 33), and the locking rods 33 are connected with the annular flange 112 in a sliding manner; the left sides of the locking rods 33 are fixedly connected with annular connecting plates 31; the right end of the locking lever 33 is fixedly connected with a locking ball 34.
The right side of the locking rod 33 is fixedly connected with an annular assembling plate 32, and the locking rod 33 is fixedly connected on the annular assembling plate 32.
