Cord winding and automatic resetting structure of take-up structure microphone cord

Abstract

The invention discloses a cord winding and automatic resetting structure of a take-up structure microphone cord. The cord winding and automatic resetting structure comprises a take-up structure assembly and the microphone cord. The take-up structure assembly comprises a take-up structure upper plate (7), a going barrel and pressing rivet nut columns (4). The going barrel comprises a coil spring seat upper cover (8), a coil spring seat (1) and a microphone cord pressing sheet (9). A guide groove (11) is formed in the top of the coil spring seat (1). Only one microphone cord can be contained on the cross section between a circle formed by the pressing rivet nut columns around the coil spring seat (1) and a POM shaft sleeve (4) and the coil spring seat (1), wherein only the pressing rivet nut column at the cord outlet position of the take-up structure assembly is provided with the POM shaft sleeve. A first resetting convex hull (5) and a second resetting convex hull (6) are arranged on the side, facing the coil spring seat (1), of the take-up structure upper plate (7). According to the cord winding and automatic resetting structure of the take-up structure microphone cord, the microphone cord is prevented from being staggered or overlapped, the microphone cord is drawn, pulled and recycled smoothly when used by a user, and user experience is good.

Description

technical field [0001] The invention relates to a take-up structure of financial equipment, in particular to a winding and automatic reset structure of a microphone line of the self-locking and self-releasing structure of the financial equipment. Background technique [0002] In the existing self-locking and self-releasing structure of financial equipment, in order to meet the use requirements of users of different heights, the length of the microphone line is relatively long. The current common structure is that multiple rows of microphone lines are overlapped and wound on the barrel. However, due to the explosion-proof requirements of the microphone cable, the microphone cable is a metal single-hook structure and double-hook structure with grooves. When multiple microphone cables are interlaced, the friction between them is relatively large, and the stress of the microphone cable is large when it is bent. Pulling and recycling are difficult. [0003] When the microphone c...

However, due to the explosion-proof requirements of the microphone cable, the microphone cable is a metal single-hook structure and double-hook structure with grooves. When multiple microphone cables are interlaced, the friction between them is relatively large, and the stress of the microphone cable is large when it is bent. Difficult to draw and recover

[0003] When the microphone cable is recycled, due to the deformation and bending of the metal microphone cable, it is easy to be vertically overlapped and staggered by the second wire at the outlet of...
