摘要

A type of locking device and automatic adjustment to be used in the snowproof anti-skid chains, characterized in that it comprises: Housing (101). Said casing (101) includes the first and second axis of rotation (1011 and 1012) established perpendicularly below the casing (101). Elastic piece of conserved energy (102) sheathed on the first axis of rotation (1011). Ratchet ratchet wheel (103), wherein limiting teeth (1031) and positioning teeth (1032) will be established at the edges of the ratchet wheel (103); the center of said rotation ratchet wheel (103) has an axis hole (1033) to be drilled by the first axis of rotation (1011). Lock buckle (104). The said locking buckle (104) has a torque hole (1041) set to match the second axis of rotation (1012), and at one end of the locking buckle (104), it also includes a fixed tooth (1042) which occludes with the limiting tooth (1031), and limits the rotation in the clockwise direction of the ratchet wheel (103). Release button (105). One end of the release button (105) is connected to the separating end between the locking buckle (104) and the fixing tooth (1042), and by pressing said release button (105), the separation will be activated. between the locking buckle (104) and the fixing tooth (1042). Revolving buckle (106). The rotating buckle (106) is attached to the end end of the release button (105), and with the pressure of the release button (105), said rotary buckle (106) is locked within the positioning tooth (1032), limiting the rotation of the opposite direction of the ratchet wheel (103). Positioning release buckle (107). The positioning release buckle (107) and the release button (105) are connected, so that when depressed downward the positioning release buckle (107) can activate the release button (105) to return it to its position initial.
