Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
As shown in figures 1 and 2, the anti-loose bolt assembly comprises
A bolt body 1 including a threaded shaft 102 and a bolt head 101;
the top surface of the nut 2 is provided with at least one first step tooth 4, and the nut 2 is screwed on the threaded rod 102;
the washer 3 is sleeved on the threaded rod 102 and is positioned between the nut 2 and the bolt head 101; the lower end face of the gasket 3 is provided with at least one second step tooth 5 and/or the upper end face of the gasket 3 is provided with at least one third step tooth 6;
when the upper end surface or the lower end surface of the gasket 3 is in contact with the nut 2, the second step teeth 5 or the third step teeth 6 of the gasket 3 and the first step teeth 4 of the nut 2 form a blocking trend in the loosening direction of the nut 2.
As shown in fig. 3, when the nut 2 is screwed onto the threaded rod 102 and tightened when the upper end surface or the lower end surface of the washer 3 contacts the nut 2, for example, the nut 2 is tightened in a counterclockwise direction and loosened in a clockwise direction with respect to the bolt body 1. Second step tooth 5 or third step tooth 6 of gasket 3 offsets with the 4 intervals of first step tooth of nut 2, and in the pine orientation of nut 2, second step tooth 5 or third step tooth 6 of gasket 3 form to block to first step tooth 4 of nut 2, consequently, when nut 2 receives rocking force or vibrations power or other environment external force to the direction action of pine, nut 2 receives blockking of second step tooth 5 or third step tooth 6 of gasket 3, the pine phenomenon of nut 2 among the reducible check bolt subassembly.
Specifically, as an alternative embodiment in this embodiment, as shown in fig. 4 and 5, the tooth mouth of the first step tooth 4 faces upward, and the screwing direction of the first step tooth 4 is opposite to the fastening direction of the nut 2.
Specifically, as an alternative implementation manner in this embodiment, as shown in fig. 1, 6, and 7, the direction of rotation of the second step teeth 5 is opposite to the direction of rotation of the first step teeth 4; the rotation direction of the third step teeth 6 is opposite to that of the second step teeth 5. When the nut 2 is loosened, the first vertical surface 401 of the first step teeth 4 also moves in the loosening direction, and the second vertical surface 501 of the second step teeth 5 thus blocks the first vertical surface 401 of the first step teeth 4 from moving in the loosening direction, thus preventing the nut 2 from moving in the loosening direction.
Specifically, as an optional implementation manner in this embodiment, as shown in fig. 1, 6, and 7, the number of the arranged teeth of the second step teeth 5 on the lower end surface of the gasket 3 is the same as or different from the number of the arranged teeth of the third step teeth 6 on the upper end surface of the gasket 3; the arrangement tooth number of the second step teeth 5 on the lower end surface of the gasket 3 is the same as or different from the arrangement tooth number of the first step teeth 4 of the nut 2.
Specifically, as an optional implementation manner in this embodiment, as shown in fig. 1, 6, and 7, the number of the arranged teeth of the second step teeth 5 on the lower end surface of the gasket 3 is smaller than the number of the arranged teeth of the third step teeth 6 on the upper end surface of the gasket 3.
As shown in fig. 8 and 9, the lower end surface of the bolt head 101 has a convex platform, the convex platform is provided with at least one fourth-step tooth 7, and the fourth-step tooth 7 has a fourth vertical surface 701. The rotation direction of the fourth-step teeth 7 is opposite to that of the third-step teeth 6. The number of the arranged teeth of the fourth-order teeth 7 is the same as or different from that of the arranged teeth of the third-order teeth 6 on the upper end surface of the gasket 3.
As shown in fig. 10, in a first embodiment of the mounting structure of the check bolt assembly, the check bolt assembly is used to connect at least one first component and at least one second component. The lower end surface of the gasket 3 is contacted with the nut 2, so that the second step teeth 5 of the gasket 3 and the first step teeth 4 of the nut 2 form a blocking trend in the loosening direction of the nut 2. In fig. 10, the anti-loose bolt assembly is connected to the first part, the second part and the third part, the fourth step of teeth of the bolt head 101 contacts with the first part to form a first frictional resistance, and the third step of teeth of the gasket 3 contacts with the third part to form a second frictional resistance, so that the bolt body 1 is not easy to rotate even under the action of the swinging force or the vibration force. The arrangement tooth number of the second step teeth 5 of the gasket 3 is smaller than that of the third step teeth 6, and the third step teeth 6 are arranged more densely to form a second friction resistance larger when being contacted with a third part. The nut 2 is tightened in the clockwise direction and makes its first step teeth 4 come into contact and come into abutment with the second step teeth 5 of the washer 3; when the nut 2 is possibly loosened due to external environmental force, the first vertical surface 401 of the first step teeth 4 also moves in the loosening direction, and the second vertical surface 501 of the second step teeth 5 blocks the first vertical surface 401 of the first step teeth 4 from moving in the loosening direction, thereby preventing the nut 2 from moving in the loosening direction.
As shown in fig. 11, in a second embodiment of the mounting structure of the check bolt assembly, the check bolt assembly is used to connect at least one first component and at least one second component. The upper end surface of the gasket 3 is contacted with the nut 2, so that the third step teeth 6 of the gasket 3 and the first step teeth 4 of the nut 2 form a blocking trend in the loosening direction of the nut 2. In fig. 11, the anti-loose bolt assembly is connected to a first part and a second part, the fourth step tooth 7 of the bolt head 101 contacts with the first part to form a first frictional resistance, and the second step tooth 5 of the gasket 3 contacts with the second part to form a second frictional resistance, so that the bolt body 1 is not easy to rotate even under the action of the swinging force or the vibration force. The nut 2 is tightened in the clockwise direction and makes the first step teeth 4 thereof contact and form an offset with the third step teeth 6 of the gasket 3; when the nut 2 is possibly loosened due to the influence of external environmental force, the first vertical surface 401 of the first step teeth 4 also moves towards the loosening direction, and the third vertical surface 601 of the third step teeth 6 blocks the first vertical surface 401 of the first step teeth 4 from moving towards the loosening direction, so that the nut 2 is prevented from moving towards the loosening direction.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
