Abstract

The utility model relates to a handle folding mechanism, which comprises a body, a handle which is in pivotal connection with the body, and a locking mechanism arranged between the body and the handle, wherein the locking mechanism comprises a rotation stopping notch which is arranged on the handle and a rotation stopping block which is elastically arranged on the body. When the locking mechanism is in locked state, the rotation stopping block is inserted in the rotation stopping notch. When the locking mechanism is in unlocked state, the rotation stopping block is disengaged with the rotation stopping notch. The folding mechanism has simple structure, and the folding operation of the handle is convenient.

Description

Handle folding mechanism

Technical field

The utility model relates to a kind of fold mechanism that is used for the handle on the household electrical appliances such as dust catcher, hair dryer.

Background technology

In the prior art, household electrical appliances such as vertical type dust collector, hair dryer are provided with handle usually, have fold mechanism between the body of handle and household electrical appliances, can make that handle is folding and take in the body to reduce the packaging volume of household electrical appliances by operating this fold mechanism.And the common more complicated of existing handle folding mechanism structure is manufactured the comparison difficulty, operates also cumbersome.

Summary of the invention

The utility model purpose provides a kind of simple in structure, handle folding mechanism of being convenient to operate.

For achieving the above object, the technical solution adopted in the utility model is: a kind of handle folding mechanism, comprise body, the handle that is connected with described body phase pivot, be arranged at the locking mechanism between described body and the handle, described locking mechanism comprises out at the spline breach on the described handle, flexibly be arranged at the spline piece on the described body.When described locking mechanism was in the lock state, described spline piece was inserted in the spline breach, and when described locking mechanism was in released state, described spline piece broke away from the spline breach.

Because technique scheme utilization, the utility model compared with prior art has following advantage: the spline piece on the operation body, make the spline piece break away from the spline breach, handle can rotate and fold and take in the body relative to body, and when handle revolution, make that the spline piece injects in the spline breach after, promptly locked between handle and the body by relative, this fold mechanism relatively simple for structure, the folding operation of handle is also more convenient.

The specific embodiment

The utility model is installed on the small household appliances such as vertical type dust collector, hair dryer, outdoor lighting device usually, and in the embodiment shown in the accompanying drawing 1-accompanying drawing 2, the utility model is installed on the vertical type dust collector, is that example specifies the utility model below with the dust catcher.

Referring to accompanying drawing 3-accompanying drawing 7, a kind of handle folding mechanism, comprise body 6, the handle 1 that is connected with described body 6 phase pivots, be arranged at the locking mechanism between described body 6 and the handle 1, described locking mechanism comprises out at the spline breach 4 on the described handle 1, flexibly be arranged at the spline piece 3 on the described body 6, described spline piece 3 is connected with body 6 phase pivots, also is provided with spline block reset torsion spring 5 between described spline piece 3 and the body 6.When described locking mechanism was in the lock state, described spline piece 3 was inserted in the spline breach 4 (seeing accompanying drawing 3-accompanying drawing 5), and when described locking mechanism was in released state, described spline piece 3 broke away from spline breach 4 (seeing accompanying drawing 6-accompanying drawing 7).Described body 6 is provided with knob base 9, and described knob base 9 head lamp brush guard pivots are connected with knob 2, are provided with knob return spring 8 between described knob 2 and the knob base 9, has the driving pin 7 that spline piece 3 can be pushed away spline breach 4 on the described knob 2.

Described body 6 is the frame of dust catcher, knob base 9 is fixedly set on the body 6, knob 2 rotates to drive and drives pin 7 rotations, as shown in Figure 7, the direction of arrow (counterclockwise) turning knob 2 according to knob 2 surfaces, drive pin 7 and promptly push spline piece 3 thereupon rotating, the active force that spline piece 3 overcomes spline block reset torsion spring 5 rotates and disengaging spline breach 4 according to clockwise direction, make handle 1 to rotate and to be folded in the body 6 that takes in dust catcher relative to body 6, and after unclamping knob 2,2 of knobs are subjected to the active force of knob return spring 8 and automatically return to original position (seeing accompanying drawing 6).As shown in Figure 6, after handle 1 was folded, handle 1 conflict spline piece 3 made locking mechanism be in released state automatically, so direct rotary handle 1 gets final product during deploying handles 1.Referring to accompanying drawing 3-accompanying drawing 5, according to counter clockwise direction rotary handle 1, when spline breach 4 faced toward spline piece 3, spline piece 3 was subjected to the active force of spline block reset torsion spring 5 according to counterclockwise rotating and injecting in the spline breach 4, is promptly automatically locked between handle 1 and the body 6.Whole fold mechanism simple in structure operated also convenient and strength-saving.
