The invention discloses a simple hook pin. The simple hook pin comprises a pin body, a first cantilever and a second cantilever, a longitudinal through hole is formed inside the pin body, and two open grooves are symmetrically formed in the outer surface of the upper portion of the pin body left and right, wherein the open grooves are communicated with the longitudinal through hole. A first hook at the upper end of the first cantilever and a second hook at the upper end of the second cantilever stretch into the longitudinal through hole and stretch out of the two open grooves respectively, the pin body, the first cantilever and the second cantilever are hinged through a connecting piece, the first cantilever and the second cantilever are fixed inside the pin body through the connecting piece, an elastic component is arranged between the first cantilever and the second cantilever and respectively exerts pressure on the first cantilever and the second cantilever to separate the first cantilever from the second cantilever, and the elastic component is located below the connecting piece. The simple pin is easy to position, a shielded sheet metal part is pressed tightly and has enough welding space, and the simple hook pin is simple in structure, easy to achieve and low in manufacturing cost.
Description
technical field [0001] The invention relates to a connecting piece, in particular to a simple deactivation pin. Background technique [0002] In the fixture design process of automobiles, simple positioning and pressing structures, pin positioning and other methods are widely used in fixture units to enhance the stability of sheet metal parts during welding and meet the welding requirements of sheet metal parts. Usually, the distribution principle of the positioning block and the pressing block is that they should be as close as possible to the welding spot to enhance the welding quality of the sheet metal assembly, and at the same time, pay attention not to affect the welding tongs to weld the sheet metal. However, in the overlapping structure of body sheet metal parts, the sheet metal parts that need to be positioned will be completely blocked by the upper assembly parts, and the ordinary positioning and pressing structure method cannot be used to control the degree of fre...
