Abstract
The utility model discloses a double-wedge tongue locking type folder, which comprises a front member, a rear member, a bolt with a grip and a double-wedge tongue member. The front member is opened box-shaped and is formed by the stamping of metal sheets. The three sides of the front member are equipped with turned-up edges. The two ends of the turned-up edges of the opening part of the front member are respectively equipped with an ear hole. The opposite edges of the opening part of the front member are isometrically equipped with three holes. The intermediate hole of the three holes is an insertion hole for the bolt with a grip and the two holes on the two sides of the intermediate hole are pilot holes for the double-wedge tongue member. The central section of the box bottom of the front member is equipped with a turned-up tilted ear. The turned-up tilted lug is equipped with a hole. The rear member is a sheet metal stamping workpiece. One edge of the rear member is equipped with a rolled coil and the other edge of the rear member is equipped with a flanging. The flanging of the rear member is equipped with two interlocking holes. The rolled coil hole of the rear member can be rotatably connected with the two ear holes of the front member and the bolt equipped with a grip is inserted into the intermediate hole. Then the bolt equipped with a grip is screwed into the screw hole of the double-wedge tongue and penetrates the turned-up tilted ear hole of the front member. After that, the end point of the bolt equipped with a grip is equipped with a washer and is matched with a pin. The two tongue tips of the double-wedge tongue penetrate the two pilot holes of the front member.
