However, if the nut is used for a long time in a harsh environment (such as a car bumping for a long time), the mechanical properties will attenuate, resulting in a decrease in the tightening force of the nut, or even loosening.
[0003] Chinese patent 201810534002.7 discloses a locking structure assembly, which has a locking structure between the nut and the part to be locked, and a locking groove is fixed on the surface of the nut, and there are locking parts and locking parts on the locking structure. The locking part, when in use, the locking groove of the nut is engaged with the locking part. Although it can realize the locking function to a certain extent, in the actual use process, since the nut and the locking part are both steel sheets, the It is difficult to snap the locking structure into the card slot during normal application, and even if it can be snapped, the nut is prone to loosening due to bumps during long-term use, so it is difficult to meet the actual application and applicability and practicality is limited

The invention discloses a locking and positioning structure, comprising a bolt and a nut, the bolt includes a stud and a nut, a locking structure is further arranged between the nut and the nut, the locking structure includes a backing plate, and the backing plate is located on the backing plate. There is a circular hole with the same diameter as the stud in the center, at least three grooves are evenly opened on the inner ring of the backing plate, a vertical slot is formed on the side wall of the stud, and the inner ring of the backing plate is provided with a vertical slot. The upper part is integrally formed with a positioning protrusion that is inserted into the vertical groove, and is also provided with a V-shaped abutting block. In the snap groove, a snap protrusion is fixed on the top end of the V-shaped pressing block, and a pressing column is fixed on the bottom end of the V-shaped pressing block. The structure of the invention is reasonable and can effectively prevent the nut from loosening. Strong applicability and good practicality.
Description
technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a locking and positioning structure. Background technique [0002] At present, when automobiles are assembled, many parts are locked and fixed by nuts. However, if the nut is used for a long time in a harsh environment (such as a car bumping for a long time), the mechanical properties will attenuate, resulting in a decrease in the tightening force of the nut, or even loosening. [0003] Chinese patent 201810534002.7 discloses a locking structure assembly, which has a locking structure between the nut and the part to be locked, and a locking groove is fixed on the surface of the nut, and there are locking parts and locking parts on the locking structure. The locking part, when in use, the locking groove of the nut is engaged with the locking part. Although it can realize the locking function to a certain extent, in the actual use process, since the nut and the lock...
