Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the embodiment provides an anti-back rivet, which comprises a rivet body 1 and a rivet sleeve 5, wherein a rivet cap 2 is fixedly connected to the top of the rivet body 1, a fastening bolt 3 is fixedly connected to the bottom of the rivet body 1, a thread groove 13 is formed in the rivet sleeve 5, the rivet body 1 is in threaded connection with the thread groove 13, a countersunk head groove 6 is formed in the top of the rivet cap 2, a limiting rod 7 is arranged in the countersunk head groove 6, and a plurality of limiting grooves 8 matched with the limiting rod 7 are uniformly formed in the top of the rivet sleeve 5;

the limiting rod 7 penetrates through the countersunk head groove 6 and is inserted into the corresponding limiting groove 8, so that the rotation of the nail sleeve 5 can be limited, loosening of the riveted workpiece due to rotation of the nail sleeve 5 caused by vibration is avoided, the phenomenon that the rivet falls off is caused, and the firmness and the stability of the rivet are improved.

Wherein, holding ring 9 fixed connection is at countersunk head groove 6 inner wall, and a pair of elastic block 10 fixed connection is at gag lever post 7 outer wall, and limiting plate 14 fixed connection is at gag lever post 7 top, can restrict gag lever post 7's position through the setting of elastic block 10, avoids gag lever post 7 roll-off spacing inslot 8 portion, influences the anti-backing effect to the rivet.

The elastic block 10 is made of elastic plastic, the top of the elastic block 10 is propped against the bottom of the positioning ring 9, and the elastic block 10 is made of elastic plastic, so that the elastic block 10 can be extruded towards the middle when the limit rod 7 is inserted into the countersunk slot 6, and the limit rod 7 is prevented from being inserted into the limit slot 8.
