Cable telescoping mechanism with segmentally stopping function

Abstract

The invention discloses a cable telescoping mechanism with a segmentally stopping function, and belongs to the field of mechanical structure design. A structure of the cable telescoping mechanism comprises a fixing plate, a connecting piece, an upper cable-winding rotary plate and a lower cable-winding rotary plate, wherein the connecting piece is fixedly connected with the fixing plate; the upper cable-winding rotary plate and the lower cable-winding rotary plate are fixedly connected with the connecting piece respectively through a bearing, so that relatively smooth rotation between the connecting piece and the upper cable-winding rotary plate and between the connecting piece and the lower cable-winding rotary plate is achieved; a cable is wound around the upper cable-winding rotary plate; a spiral spring is arranged between the upper cable-winding rotary plate and the lower cable-winding rotary plate, the inner end of the spiral spring is connected with the connecting piece, and the outer end of the spiral spring is partially connected with the upper cable-winding rotary plate and the lower cable-winding rotary plate; besides, a spring pin is arranged on the fixing plate, one end of the spring pin is rotatably connected with the fixing plate, and the other end of the spring pin is in mutual movement matching with the lower cable-winding rotary plate, so that free switching between self locking and back rotation in a cable rotation process is achieved. According to the cable telescoping mechanism with the segmentally stopping function, the free switching between the self locking and the back rotation in the cable rotation process can be achieved; besides, the quality of electrical signals is effectively ensured; the cable telescoping mechanism has the advantages of reasonable structural design, novel conception, firmness in connection and convenience in use.

Description

technical field [0001] The invention belongs to the field of mechanical structure design, in particular to a cable telescopic mechanism with segment stop function. Background technique [0002] The modern financial market is developing rapidly, and there are many types of terminal products used in the financial market. Modules such as telephones occupy an important position as a mandatory part of most products. Most of the products in the market now use the wiring method like a public telephone, and the wiring of the call handle is external, which not only affects the appearance of the product because of too many exposed lines, but also poses a great safety hazard. In the existing telephony module, there are also various problems such as not having an anti-return structure, poor call signal, and the like. Contents of the invention [0003] The present invention provides a cable retractable mechanism with segment stop function aiming at the current demand and the shortcomi...
