Description

Winder with take-up speed retarding mechanism

Technical Field

The invention relates to a winder on electrical equipment, in particular to a winder with a wire winding speed slowing mechanism.

Background

In electric appliances such as a vacuum cleaner, a power cord portion is generally stored in a cord reel. At present, the conventional winder design utilizes the compressed elastic force of a coil spring to rotate a winding roll, so as to achieve the wire winding effect of a power line.

However, the take-up mode mainly has the following disadvantages: in the resetting process of the coil spring, the inertia is larger and larger, so that the wire winding speed is higher and higher, the power plug is thrown, a user is easily injured or other objects are touched, and even the power line falls off due to the collision of the power plug with a machine body.

In view of this, the invention provides a reel with a take-up speed slowing mechanism, which can improve the safety and stability of the reel in use and effectively prolong the service life of the whole reel.

To this end, the present invention provides a line winder having a take-up speed relaxing mechanism, comprising:

a winding roll rotatably mounted on a winding support, the winding support having a support insert embedded in a central circular hole of the winding roll;

deformable loop forming element, it is installed in the central round hole, and fixedly connected with at least one brake block on the outer fringe of loop forming element, brake block sliding connection is in the surface of take-up reel simultaneously, and brake block along the radial of take-up reel make a round trip to slide and drive the loop forming element and warp.

Further, the ring-shaped member is a circular ring-shaped member.

Further, the annular member is formed by splicing two semicircular members.

Furthermore, the splicing part of the two semicircular pieces extends outwards to form a connecting part, and the connecting part is fixedly connected with the brake part.

Furthermore, the end part of the semicircular part is outwards formed into a bent end, and the two bent ends are spliced to form a connecting part.

Further, the ring-shaped member is a copper ring-shaped member.

Further, the brake component is a brake pad.

Further, the brake pad is an arc-shaped pad.

Furthermore, the surface of the winding roll is provided with a sliding cavity for the sliding of the brake component.

Furthermore, a sliding guide rib arranged along the radial direction of the winding roll is arranged in the sliding cavity, and a sliding groove connected to the sliding guide rib in a sliding mode is arranged at the bottom of the brake component.

In the winder with the winding speed slowing mechanism, the two brake parts (specifically the first brake pad and the second brake pad) can move outwards towards two sides by the centrifugal force generated by rotation of the winder during winding, the two brake parts drive the ring part to stretch, the shape of the ring part is changed from circular to elliptical, then the ring part and the bracket insert have little interference, so that the friction force generated during rotation can be increased, and finally the purposes of slowing down the rotation speed of the winder and reducing the winding speed are achieved, so that the collision speed and the collision force of a power line plug and the whole machine are indirectly reduced, the safety and the stability of the winder during use can be improved compared with the prior art, and the service life of the whole machine is effectively prolonged.
