Drawings
Fig. 1 is a schematic structural view of the bolt connection structure of the present invention before the nut is locked;
fig. 2 is a schematic structural view of the bolt connection structure after the nut is locked;
fig. 3 is a schematic structural view of a rubber sealing sleeve according to another embodiment of the present invention.
In the figure: 1 treat connecting piece, 100 connecting holes, 2 bolts, 3 nuts, 300 first tooth-shaped structures, 4 first locking pieces, 400 second tooth-shaped structures, 5 second locking pieces, 6 rubber sealing sleeves, 7 first sealing rings, 8 second sealing rings and 9 hard structure pieces.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the leak-proof sealed fastening bolt connecting structure comprises a to-be-connected member 1, a bolt 2, a nut 3, a first locking sheet 4, a second locking sheet 5 and a rubber sealing sleeve 6.
The nut 3, the first locking piece 4, the rubber sealing sleeve 6 and the second locking piece 5 are sequentially sleeved on the bolt 2 from the tail part of the bolt 2 to the head part of the bolt 2. Treat to offer connecting hole 100 on the connecting piece 1, bolt 2 is pegged graft with this connecting hole 100, and rubber seal cover 6 sets up in connecting hole 100, and two stay respectively with treat the both ends butt of connecting piece 1, first stay 4 and treat and set up first sealing washer 7 between connecting piece 1, second stay 5 and treat and set up second sealing washer 8 between connecting piece 1. Specifically, the first locking piece 4 and the second locking piece 5 are both of metal structures. A circle of first groove is formed in the end face, facing the to-be-connected piece 1, of the first locking piece 4, and the first sealing ring 7 is embedded in the first groove. A circle of second groove is formed in the end face, facing the to-be-connected piece 1, of the second locking piece 5, and the second sealing ring 8 is embedded in the second groove.
The end surface of the nut 3 facing the first locking piece 4 is provided with a circle of first tooth-shaped structure 300, the end surface of the first locking piece 4 facing the nut 3 is provided with a circle of second tooth-shaped structure 400, and the first tooth-shaped structure 300 is meshed with the second tooth-shaped structure 400. The arrangement of the two tooth-shaped structures can enable the connection between the nut 3 and the first locking piece 4 to be tighter, and the nut is prevented from loosening.
In a relaxed state, the length of the rubber sealing sleeve 6 is greater than that of the connecting hole 100, and the outer diameter of the rubber sealing sleeve 6 is smaller than that of the connecting hole 100; after being extruded by the two locking pieces, two ends of the rubber sealing sleeve 6 are respectively abutted against the two locking pieces, and the outer wall of the rubber sealing sleeve 6 is tightly attached to the inner wall of the connecting hole 100.
As shown in fig. 3, in another embodiment of the present invention, a plurality of hard structural pieces 9 are uniformly and annularly adhered to the inner wall of the rubber sealing sleeve 6, and the hard structural pieces 9 can be made of metal material or plastic material. When the bolt 2 inserts the rubber seal cover 6, the stereoplasm structural slab 9 can be more smoothly inserted by the bolt 2, when the bolt 2 inserts the rubber seal cover 6 completely, because the elasticity of rubber seal cover 6 self, can still laminate completely between bolt 2 and the rubber seal cover 6.
The utility model discloses a rubber seal cover 6, first sealing washer 7 and second sealing washer 8 are to the bolt and treat that the connection structure between the connecting piece carries out the sealed protection of full aspect, have very strong leak protection, sealing performance.
