Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 5, a circlip nut for fastening includes a supporting surface 1, a through hole for allowing a bolt 3 to pass through is formed in the middle of the supporting surface 1, a sleeve 2 adapted to the bolt 3 in a threaded manner is fixed at the bottom of the supporting surface 1, the sleeve 2 and the through hole on the supporting surface 1 are coaxially arranged, and the inner diameter of the sleeve 2 is the same as the outer diameter of the through hole;

two clamping jaw structures are arranged on the end surfaces of two sides of the supporting surface 1; the clamping jaw structure comprises a connecting plate 7, two L-shaped clamping plates 8 are symmetrically arranged at two ends of the connecting plate 7, one ends, far away from the connecting plate 7, of the two L-shaped clamping plates 8 are fixed to the side end face of the supporting face 1, L-shaped clamping ribs 9 are further fixed to the middle of the connecting plate 7, the width of each L-shaped clamping rib 9 is smaller than that of each L-shaped clamping plate 8, and a distance is reserved between one end, close to the supporting face 1, of each L-shaped clamping rib 9 in the middle of the connecting plate 7 and the corresponding end of the L-shaped clamping rib 9;

the two connecting plates 7 are different in height and are staggered and misaligned in projection on the vertical plane, one connecting plate 7 arranged at the upper end is arranged parallel to the supporting surface 1, and arc-shaped process notches are formed in two end faces, which are not connected with the jaw structure, of the supporting surface 1.

A distance is reserved between the two connecting plates 7, so that the bolt 3 can penetrate through the L-shaped clamping plate 8 and the connecting end of the supporting surface 1 when the connecting end deforms.

Refer to fig. 4 and divide into left side jack catch and right side jack catch with two jack catch structures, external force is applyed to both positions outside-in, makes L shape joint board 8 inwards warp, through the rectangular hole of being convenient for its passing through of seting up on the supporting body 5, because of left L shape joint muscle 9 and the L shape joint muscle 9 on right side are disconnected with holding surface 1, in the deformation process, have reduced the external force that required was applyed. Meanwhile, the upper surface of the connecting surface 7 of the left jaw structure is lower than the lower surface of the connecting surface 7 of the right jaw structure, and the left connecting surface and the right connecting surface are overlapped in a staggered mode during installation, so that assembly is facilitated.

When assembling, as shown in fig. 5, after the circlip nut is assembled to the carrier 5, the bolt 3 passes through the mounting hole 10 of the connected piece 4, the bolt 3 is in threaded connection with the inner wall of the sleeve 2, and the connected piece 4 is fastened to the carrier 5. In the process that the bolt 3 is continuously screwed, the head of the bolt is firstly contacted with the left and right connecting surfaces 7, then force is applied to the two connecting surfaces 7, the two connecting surfaces are pushed outwards, and the left and right L-shaped clamping plates 8 are deformed towards two sides. The left and right L-shaped clamping plates 8 are in contact with the boundaries of rectangular holes formed in the bearing body 5, so that the clamping spring nut cannot be separated from the bearing body 5.
