Abstract

La presente invención proporciona una silla plegable que comprende dos patas tubulares delanteras, dos patas tubulares traseras, y una tabla acolchonada de asiento. Una de las patas tubulares delanteras se entrecruza con una de las patas tubulares traseras, en donde además comprende dos arandelas, cada una se dispone en una intersección de las patas tubulares delanteras, es decir, esta arandela se encuentra entre la pata tubular delantera y la pata tubular trasera. Un perno atraviesa la pata tubular delantera, la arandela y la pata tubular trasera sucesivamente. La arandela se proporciona de una base curva y un soporte en forma de cuenco que se ubica en una zona central de la base curva y se forma un agujero pasante en el centro del soporte en forma de cuenco; y la base curva se conecta de manera fija a las patas tubulares delanteras. El efecto beneficioso de la presente invención es que la arandela, que se dispone en la pata tubular delantera, tiene una base curva y un soporte en forma de cuenco, y la base curva se adapta a la forma de la superficie de las patas tubulares para conectarse firmemente a las patas tubulares, y la pata tubular delantera se separa de la pata tubular trasera a través del soporte en forma de cuenco, de modo que dicha estructura puede reducir la fricción entre las dos patas tubulares para evitar el pellizco, y puede mejorar su capacidad de carga al tiempo que reduce el peso de la silla plegable. De acuerdo con la presente invención, la silla plegable puede obviamente aumentar la resistencia ante la prueba de impacto.
