Retaining rivet and antenna

Abstract

The invention discloses a retaining rivet and an antenna. According to the technical scheme of the retaining rivet, the retaining rivet is characterized by comprising a pin and a pin bush, wherein a pin hole capable of allowing the pin to penetrate therethrough is formed in the pin bush, the outer wall of one end of the pin bush protrudes to form an extending part, the other end of the pin bush can be elastically folded outwards and the extending part jointly form a tensioning part with a clamping effect, the inner wall of the tensioning part protrudes to form a retaining part capable of enabling the tensioning part to be folded outwards when the pin is inserted into the pin hole, and the outer side wall of the pin is provided with a locking part matched with the retaining part in a clamped mode so as to prevent the pin from retreating from the pin hole. When the pin is inserted into the pin hole, the pin interacts with the retaining part, so that the tensioning part is folded outwards, the locking part on the outer wall of the pin and the retaining part on the pin bush form the clamping effect, and the retaining part and the locking part are kept in a clamping state through the interaction force of the tensioning part and a plate and the elastic recovery force of the tensioning part, so that the pin is prevented from being separated from the pin bush, and the stability of therivet fixing effect is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an anti-retreat rivet and an antenna. Background technique [0002] At present, the assembly methods of the internal parts of the antenna are mostly fixed by plastic rivets. The plastic rivet structure is generally composed of a pin and a pin sleeve. The pin squeezes the pin sleeve to expand the pin sleeve to fix the two parts that need to be connected. The pin The pin sleeve maintains the assembly form through extrusion friction to achieve the role of fixing parts. The extrusion surface is mostly in point-to-surface contact. During the transportation of the antenna, the pin is easily separated from the pin sleeve due to vibration, and the fixing effect is unstable. Contents of the invention [0003] The object of the present invention is to provide a back-stop type rivet that can prevent the pin from being separated from the pin sleeve and thereby improve the fixi...
