Abstract

A shoelace tightness adjustment device, comprising a connection mechanism (1) and a traction mechanism (2). The traction mechanism (2) comprises a traction assembly (21) and an elastic adjustment assembly (22). The traction assembly (21) comprises a loop member (211). The elastic adjustment assembly (22) comprises a connection block (221), clamping blocks (222), an elastic member (223) and a linkage member (224), wherein engagement portions (4) are movably connected to both ends of the connection block (221), the engagement portions (4) are detachably connected to the loop member (211), and the connection block (221) separates the loop member (211) into two lace holes for shoelaces to pass therethrough; two clamping blocks (222) are provided and are both hinged to the peripheral side of the connection block (221); the elastic member (223) is used for forcing the two clamping blocks (222) away from each other; the clamping blocks (222) are connected to the engagement portions (4) by means of the linkage member (224); and when the two clamping blocks (222) are squeezed together, the linkage member (224) forces the engagement portions (4) to disengage from the loop member (211).
