Charger and wire coiling structure capable of locking unlocking

Abstract

A wire coiling structure capable of locking and unlocking includes a bottom box, an inner core, a volute spring, a cover plate and a pawl assembly. The bottom part of the bottom box protrudes towards the inner side of the box and forms a protruding shaft. A first clamping groove is formed in the protruding shaft in the axial direction. The inner core is provided with a fixed board, a ratchet wheel and a wire arrangement wall body. The ratchet wheel and the wire arrangement wall body are arranged on two faces of the fixed board. A second clamp groove is arranged in the wire arrangement wall body. Two ends of the volute spring are respectively fixed in the first clamping groove and the second clamping groove. The cover board is arranged at the opening end of the bottom box in a covering manner. The pawl assembly includes a pawl, a spring and a knob. The spring sleeves the pawl. The knob is connected with one end of the pawl. The other end of the pawl extends into the bottom box to fit with the pawl. A wire coils the wire arrangement wall body of the inner core and the coiling and uncoiling of the wire are realized by utilizing the elastic potential of the volute spring. The pawl and the ratchet wheel fit with each other so as to realize locking and unlocking. At the same time, the invention also provides a charger employing the coiling structure capable of locking and unlocking.

Description

technical field [0001] The invention relates to the field of wire take-up technology, in particular to a charger and a wire take-up structure capable of self-locking and unlocking. Background technique [0002] Portable lamps need centralized charging management during charging and use. Due to the large number of chargers, it is easy to cause the charging cables to be entangled with each other, which brings inconvenience to centralized charging management. At present, the take-up device is mainly used to solve the problem of intertwining between charging cables. [0003] However, after the traditional wire take-up action is completed, the inner core of the wire take-up device is easy to rotate under the action of an external force, so that the collected cable is released again, which affects the wire take-up function. Contents of the invention [0004] Based on this, it is necessary to address the above problems and provide a self-locking and unlocking charger and a self-...
