The invention relates to the field of automatic fastening devices, in particular to a connecting rod type automatic locking device. The device comprises a speed reducer for providing power, a driving disc, a driven disc and a switch shifting fork, an output shaft of the speed reducer is fixedly connected with the driving disc, and the driving disc is connected with the driven disc through an adjusting connecting rod assembly and drives the driven disc to rotate to drive a handle to rotate to achieve locking. The adjusting connecting rod assembly comprises a main connecting rod and an auxiliary connecting rod which are connected through a double-thread screw and a connecting rod fixing piece, the main connecting rod is connected with the driving disc, and the auxiliary connecting rod is connected with the driven disc. By adjusting transmission of the connecting rod assembly, the defects existing in original chain transmission can be overcome, compared with chain wheels, the connecting rod structure can save the machining cost by about 80%, the problems that pin shaft abrasion, pin shaft and sleeve gluing, tooth skipping, shaking, locking element loosening, violent vibration, too large noise and the like influence locking/unlocking rotation are avoided, and regular oil stain removing, lubricating grease filling and the like on a chain by maintenance personnel are avoided.

    本发明及一种自动紧固装置领域,具体涉及一种连杆式自动锁紧装置。包括提供动力的减速机、驱动盘、从动盘和开关拨叉,减速机的输出轴与驱动盘固定连接,驱动盘通过调节连杆组件连接从动盘、并驱动从动盘转动以带动手柄转动实现锁紧;调节连杆组件包括主连杆和从连杆,主连杆与从连杆之间通过双头螺杆和连杆固定片连接,主连杆连接驱动盘,从连杆连接从动盘。本发明通过调节连杆组件传动,可以解决原有链条传动所存在的弊端,连杆结构对比链轮加工成本可节省80%左右,不会发生销轴磨损、销轴与套筒胶合、跳齿、抖动、锁止元件松动、振动剧烈、噪音过大等影响锁紧/解锁转动问题的发生,以及免去维保人员定期对链条上油污清理以及润滑脂加注等。
