Lateral stabilizer device for working ladder
Disclosed is a lateral stabilizer device for a working ladder. An opening-closing body (11) is respectively arranged on the left and right of a working ladder (1), a supporting leg (13) is respectively arranged on outer sides of the front and back of the opening-closing body (11), at least one supporting leg (13) is provided with a support accommodating groove (131) which is inwardly recessed from an outer side, and a lateral stabilizer device (2) is fixedly connected to the bottom side of the at least one supporting leg (13). The lateral stabilizer device (2) is provided with a rotary connection seat (21), the rotary connection seat (21) is provided with a rotary connection groove (22) corresponding to the support accommodating groove (131), and an assembly penetration hole (23) penetrates the inner side of the rotary connection groove (22). A rotary swing shaft (3) is inserted into the rotary connection groove (22), a first rotary spring (4) is sleeved on the rotary swing shaft (3), and a rotary swing support (5) is pivoted with the rotary swing shaft. A ratchet wheel (51) is fixedly connected to the rotary swing support (5), and ratchet teeth (52) are distributed around the ratchet wheel (51); and a ratchet swing assembly (6) is lapped above the ratchet wheel (51), and one side of the ratchet swing assembly (6) is provided with a pawl (61) meshed with the ratchet teeth (52). An assembly shaft (7) pivoted with the ratchet swing assembly (6) is inserted into the rotary connection groove (22), and a second rotary spring (8) is sleeved on the assembly shaft (7).
