Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 11, a snap ring nut includes: the nut is composed of a nut 1 and a stop ring 2, at least one surface of the nut 1 is connected with the stop ring 2, the stop ring 2 is a hollow circular ring, and a second through hole 21 is formed in the center of the circular ring; the center points of the first through hole 11 of the nut 1 and the second through hole 21 in the stop ring 2 are positioned on the same axis; the inner wall of the first through hole 11 of the nut 1 is provided with internal threads, and the inner diameter of the circular second through hole 21 of the stop ring 2 is equal to or slightly larger than the diameter of the external threads 31 on the screw rod of the bolt 3; the diameter of the stop ring 2 is equal to or larger than that of the nut 1, and the edge of the stop ring 2 is circular or polygonal; the height of the second through hole 21 of the stop ring 2 is provided with a minimum value; the external thread 31 of the screw rod of the bolt 3 is connected with the internal thread of the nut 1, the external thread 31 of the screw rod rotates to enter the second through hole 21 of the stop ring 2, and the external thread 31 is in high-precision sleeved connection with the inner wall of the second through hole 21; the nut 1 and the stop ring 2 are connected by welding, or the nut 1 and the stop ring 2 are manufactured by integral molding; according to the requirement, a metal or plastic hollow pipe is arranged in the second through hole 21, and after connection, the hollow pipe is positioned between the external thread 31 and the inner wall of the second through hole 21 and is clamped.
Specifically, the screw of the bolt 3 is connected with the nut 1, the external thread 31 of the screw in the bolt 3 is screwed into the second through hole 21 of the stop ring 2, and the internal walls of the external thread 31 and the second through hole 21 are mutually attached and connected, so that high-precision sleeving connection is realized. Bolt 3 through screwing power with nut 1 screws, when meetting lateral vibration, the locking post second through-hole 21 with on the screw rod external screw thread 31 closely laminates, lets bolt 3 with can't produce between the nut 1 and rock. Thus, the horizontal displacement between the bolt 3 and the nut 1 caused by the transverse vibration can be counteracted to the maximum extent. By offsetting the lateral displacement on the horizontal plane, the lateral displacement between the bolt 3 and the nut 1 can be eliminated or reduced to a very small value, and the bolt 3 and the nut 1 can be firmly connected through the screwing force of the bolt 3.
The nut 1 is a conventional flange face hexagon head nut 1, the stop ring 2 is circular in the second through hole 21, the outer edge of the stop ring 2 is circular or polygonal, and the stop ring 2 with a larger diameter can also be used as a gasket.
According to the requirement, a hollow pipe is arranged on the inner surface of the stop ring 2, the hollow pipe is positioned between the external thread 31 and the inner wall of the second through hole 21, and the external thread 31 and the inner wall of the second through hole 21 are more tightly connected and fixed by the extrusion force generated by the hollow pipe.
The stop rings 2 are provided on both sides of the nut 1, so that the external thread 31 can be more effectively fixed in position. That is, the second through hole 21 of the stop ring 2 is used to fix the position between the nut 1 and the screw, so as to prevent the nut from moving horizontally or shaking. The screw connection between the bolt 3 and the nut 1 is more of a fastening connection by a tightening force.
The second through hole 21 of the stop ring 2 needs to have a certain height, so that the external thread 31 of the screw rod entering the second through hole 21 is not easy to shake left and right, and the height of the screw rod changes within a range of 3-50 mm. In addition, when the bolt 3 is connected with the nut 1, the bolt is also a stress point, and the combination of the stress point and the stress point is beneficial to the external thread 31 to be more stably sleeved in the second through hole 21.
