Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides two kinds of technical scheme:

referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a locking double drum rivet, including nail pole 1, the one end fixed mounting of nail pole 1 has pressure head 2, nail pole 1 has cup jointed the rivet body 3, 3 one ends of rivet body are equipped with convex surface 4, the one end of nail pole 1 runs through the inner chamber and the pressure head 2 fixed welding of rivet body 3, 3 inner wall left and right sides from the top down of rivet body are provided with two first lugs 5, 1 upper end surface cover of nail pole is equipped with bulge loop 6, the position of bulge loop 6 and the position looks adaptation of first lug 5, the opening has been seted up to the 3 left and right sides of rivet body, the equal slidable mounting in the 3 left and right sides of rivet body has second lug 7, and horizontal slip is done to second lug 7 in the opening, 7 relative one side upper end fixed mounting of second lug has stopper 8.

Utilize between bulge loop 6 and the first lug 5 mutually support fixedly, can make nail pole 1 can not appear not hard up when the installation and rock the condition such as, stability is better, is spacing to the fixture by the 7 roll-off of pulling messenger second lug when nail pole 1, the skew appears when can avoiding using.

Fig. 1 to 3 also show a second embodiment, the main differences from the first embodiment being:

the lower end of the pressure head 2 is fixedly provided with a rubber pad 9, the upper end of the convex surface 4 is fixedly provided with a first anti-skid pad 10, the surface of the rivet body 3 contacting with a fixed object is fixedly provided with a second anti-skid pad 11, and the connection mode of the nail rod 1 and the pressure head 2 is fixed welding.

The rubber pad 9 and the non-slip pad can be used for stabilizing the rivet body during installation and preventing shaking.

During the use, insert the nail pole 1 in the rivet body, bulge loop 6 cooperatees fixedly with first lug 5, press from both sides tight rivet with the riveter when installing, insert the rivet in the through-hole that needs the fixture afterwards, draw nail pole 1 from the outside from the riveter, under the effect of pulling force, nail pole 1 promotes 7 roll-offs of second lug and stabilizes whole, because nail pole 1 is fixed connection with pressure head 2, thereby can be with nail pole 1 upwards spurs, then the pressure head 2 that sets up can extrude the rivet body 3, can extrude positioning channel groove into two drum shapes, continue to pull nail pole 1, 3 upper portions of rivet body can't continue to warp, lead to the unable continuation of nail pole 1 and spur, make the sudden increase of fracture department atress, fracture department disconnection, like this, rivet on the fixture together of rivet body 3 and nail pole 1 part, play sealing effect.
