Problems solved by technology

The cord reel of the vacuum cleaner generally uses a scroll spring to store force, the winding speed is very fast, and the winding force is also very large. Therefore, the impact force received by the pawl-type brake structure is very large, and the pawl and ratchet are generally made of plastic. into, easily broken
In addition, the spool of the pawl type brake will make noise when it rotates in one direction

Embodiment Construction

[0034] figure 1 It is a three-dimensional structure schematic diagram of the cord reel of the present invention. Such as figure 1As shown, the cable reel of the present invention includes a brake lever 1, a rubber wheel 2, a rear panel 3, an inner hub 4, an outer hub 5, a spring fixing plate 6 and a scroll spring 7, and the above-mentioned components are installed together in sequence. The inner hub 4 and the outer hub 5 constitute a part of the wire wheel assembly, which are used for winding the cable. When the brake structure of the cable reel of the present invention is in the braking state, the cable can be pulled out from the wire wheel assembly in one direction. At this time, the scroll spring 7 stores force through the spring fixing plate 6; In the normal state, the elastic force accumulated in the scroll spring 7 is released, and the cable is collected into the wire wheel assembly.

Abstract

The invention discloses a braking structure of a reel, which comprises a ratchet-pawl braking component and a friction braking component, wherein the ratchet-pawl braking component and the friction braking component can realize ratchet-pawl braking and friction braking respectively through an identical pushing component. Further, the pushing component comprises a braking lever and a spring, the braking lever is provided with a body and a first braking portion, one end of the body is connected with the spring, and the first braking portion is formed at the other end of the body and extends from the other end of the body. By means of simple structural improvement, a double-braking function is realized, the problems that a rubber wheel fails in braking due to easiness in being heated, and a ratchet is easy to be collided and damaged in braking are effectively solved, impact force during braking can be effectively reduced, and braking failure is prevented.

Description

technical field [0001] The invention relates to a braking structure, in particular to a braking structure of a wire reel. Background technique [0002] At present, the brake function of the wire reel on the vacuum cleaner can be realized by two kinds of brake structures, one is a brake lever type (or friction brake) buffered by friction wheels, and the other is a ratchet pawl type (or ratchet brake). claw brakes), there are disadvantages between the two. [0003] Chinese Patent Application No. 200510006796.1 and Chinese Utility Model Patent No. 200920201463.9 each disclose a cord reel, which adopts a frictional brake structure. by Figure 7 The structure shown is an example to illustrate this type of brake structure. The friction brake includes a structure 70 , a brake lever 71 , a friction wheel 72 , a spring 76 and a wire wheel assembly (not shown) inside the structure 70 . The structural member 70 is provided with a slide groove 702 , and the brake lever 71 is radially...
