Embodiment

[0022] see in conjunction figure 1 , figure 2 with image 3 , the present embodiment takes the banknote outlet gate module of the bank automatic teller machine as an example, a rotating shaft 9 is arranged in the module body, and the two ends of the rotating shaft 9 are arranged on the opposite side plates through bearings, and the active link mechanism One end of the connecting rod 6 is fixed on the rotating shaft 9 and rotates with the rotating shaft 6, the other end of the active connecting rod 6 is hinged with one end of the driven connecting rod 7 of the linkage mechanism, and the other end of the driven connecting rod 7 and the gate plate 8 pass through the connecting block 13 Hinged, the connecting rod mechanism drives the gate plate 8 to rotate around the gate rotating shaft 1 to realize the closing of the opening box of the gate; there are two connecting rod mechanisms, which are respectively arranged at the two ends of the rotating shaft 9 . A cam 4 is provided in...

Abstract

The invention discloses a connecting link-cam dual self-locking mechanism which comprises link mechanisms and a cam, wherein one end of each of the link mechanisms is fixed on a rotating shaft and rotates with the rotating shaft, the other end of the link mechanism is hinged with a moving part, the cam is sleeved on a camshaft and rotates with the camshaft, a cam roller is installed on an active connecting link of the link mechanism through a pin shaft and contacts with the cam, and the position of a repose angle of motion of the cam roller on the cam is identical to the dead center positions of the motion of the link mechanisms. According to the invention, a motor drives the cam which then drives the link mechanisms to move, which enables motor-driven torque to be substantially reduced; and dual self-locking mechanism is realized through the repose angle of cam motion and the dead centre positions of the motion of the link mechanisms, the cam is a grooved cam, so compactness of the structure of the dual self-locking mechanism is guaranteed.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and in particular relates to a double self-locking transmission mechanism combined with a connecting rod and a cam. Background technique [0002] Due to its simple and compact structure and fast transmission, the linkage mechanism is frequently used in financial equipment. [0003] For example, the gate used by the cash outlet of the bank's automatic teller machine uses a motor to drive the crank linkage mechanism. The crank linkage mechanism is connected to the gate plate to realize the opening and closing of the gate, and the movement dead point of the linkage mechanism is used to realize The self-locking of the gate when it is closed prevents the cash withdrawal port from opening by itself under the action of external force. [0004] However, in actual operation, if a power source such as a motor or a rotating motor is used to directly drive the active link of the linkage mechanism, the...
