Detailed Description
The utility model provides a press and rivet formula pin structure. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
A press-riveting pin structure is shown in figures 1 and 2, the press-riveting pin is used for locking a plate 1 and a fixed base body 2, the press-riveting pin comprises a press cap 3 and a pin rod 4, and a radially outward locking end 20 which is used for locking the fixed base body 2 is arranged at the free end of the pin rod 4.
Specifically, the locking end 20 is similar to a conventional ring rib, but the locking end 20 is disposed at the free end of the pin rod 4, so that after the press-riveting fit is completed, no space interference is caused by the exposed pin rod 4.
In the present case, press cap 3 to be equipped with the pile platform towards the extension of pin rod including pressing cap main part 5 on pressing cap main part 5, the pile platform is equipped with ring muscle 6 towards the one end of pin rod, ring muscle 6 and press to be formed with between cap main part 5 and have annular recess 7.
The plate 1 is provided with a limit ring groove 8 matched with the ring rib 6, a limit ring rib 9 matched with the ring groove 7 and a sunk groove 10 for accommodating the pressing cap main body.
The specific implementation process and principle description are as follows:
when the plate 1 and the fixing base body 2 are press-riveted and assembled, the pin rod 4 is firstly inserted into the insertion passage of the plate 1 and the fixing base body 2 to be opposite, and at the moment, the press-riveting matching operation is carried out on the press cap 3.
The lock catch end 20 of the pin rod 4 is fixedly matched with the fixing base body 2 in a press riveting mode, the ring rib 6 penetrates through the limiting ring rib 9 to be fixedly matched with the limiting ring groove 8 under the action of extrusion force, the limiting ring rib 9 is embedded into the ring groove 7 to achieve tight fit, and the pressing cap main body is mounted in the sinking groove 10 in a concealed mode, so that locking between the pin rod 4 and the fixing base body 2 and locking between the pressing cap 3 and the plate 1 are achieved, the relative locking requirements of pins, plates and the fixing base body are met, and the locking stability is excellent. In addition, both ends of the pin are hidden, and the pin cannot be exposed to cause exposure interference.
It should be noted that, the fixed base member in the present case is plastic material base member, and panel is sheet metal, and both materials have the difference, and consequently two pressure riveting fixed knot construct fixed more firm stable.
In a preferred embodiment, the limiting ring rib 9 is provided with an assembly guiding conical surface 91, which satisfies the smoothness of the ring rib 6 passing through during the crimping process, and does not cause the crimping damage to the limiting ring rib 9.
