Abstract

The utility model discloses a spiral rod automatic rotation structure, which comprises a spiral rod, a rotation element, a torsional spring, a fixed ring, a base and a pulling element. When the spiral rod automatic rotation structure is used, dust removing cloth is sheathed on the spiral rod and the rotation element, the rotation element is rotated to make the dust removing cloth form a spiral state on the spiral rod, and the rotation element is rotated to clamp and butt a tooth part arranged in the rotation element through the pulling element, so the dust removing cloth is maintained at the spiral state, and the torsional spring generates the torsional force when the rotation element is rotated. Thereby, when the pulling element is moved to leave the tooth part of the rotation element, the rotation element generates automatic reverse rotation action by using the torsional force of the torsional spring to reach the goal of replacing the dust removal cloth.

The specific embodiment

In order to reach the purpose of this utility model and effect, the accompanying drawing of now arranging in pairs or groups, the preferred embodiment that develops simultaneously is described in detail as follows, so that the people who has common knowledge in this area can be implemented according to this.

At first, see also Fig. 3～Figure 13, it is respectively schematic perspective view, three-dimensional exploded view, partial schematic diagram, cutaway view and the preferred embodiment figure of the automatic rotational structure of the utility model screw rod, knows among the figure and points out that whirligig 2 includes:

Screw rod 3, it mainly is made up of the elongated end 32 that an end of the body of rod 31 and the body of rod 31 extends, and the end of elongated end 32 also is formed with the fixture block 321 of two correspondences, and be concaved with groove 33 by end;

Revolving part 4, its inside are provided with wears groove 40, and revolving part 4 is sheathed on outside the elongated end 32 of screw rod 3, is equipped with tooth portion 41 on its inwall, and what the outside then was formed with two correspondences colludes body 42;

Torsion spring 5, it is sheathed on the elongated end 32 of screw rod 3, and the one end is formed with bending end 51, and the other end then is formed with fastening end 52, and torsion spring 5 is when being sheathed on the elongated end 32 of screw rod 3, and bending end 51 is positioned at the groove 33 of elongated end 32;

Retainer ring 6, it is sheathed on elongated end 32 ends of screw rod 3, and the one side is extended with the convex body 61 of two correspondences;

Pedestal 7, it is incorporated into revolving part 4 one ends, pedestal 7 is formed with storage tank near an end inside of revolving part 4, the elongated end 32 of screw rod 3 places within its storage tank 70, in the storage tank 70 and be provided with the perforation 71 of two correspondences, and one side be provided with chute 72, in addition, on two corresponding surfaces of pedestal 7 and be provided with the decoration body 74 of two above diamond forms;

Shifting part 8, it is arranged at pedestal 7 one sides, in order to the tooth portion 41 in the conflict revolving part 4, and is provided with flexible member 81 in the other end of conflict tooth portion 41.

When using the automatic rotational structure of the utility model screw rod, mainly be that dust removing cloth 9 is sheathed on outside the screw rod 3 and revolving part 4 of whirligig 2, and make dust removing cloth 9 on screw rod 3, form the state of a spiral by rotating revolving part 4, carrying out different cleaning effects by the multi-angle that this spiral status was produced.And whirligig 2 also can be connected with a flexible body of rod A1 by the fixed part 73 of pedestal 7 one sides, make whirligig 2 can carry out the cleaning action of different distance, and can adjust the angle of whirligig 2 by the press section A3 of flexible body of rod A1 by hand-held flexible body of rod A1.

Wherein, when screw rod 3, revolving part 4 is with after pedestal 7 combines, the convex body 61 of retainer ring 6 is embedded in the perforation 71 of pedestal 7, and the bending end 51 of torsion spring 5 is positioned at the groove 33 of elongated end 32,52 of fastening ends are embedded on the inwall of revolving part 4, therefore when rotating revolving part 4, because the bending end 51 of torsion spring 5 is subjected to groove 33 restrictions of elongated end 32, the fastening end 52 of the other end then is subjected to the inner wall limit of revolving part 4, torsion spring 5 produces torsion at this moment, but because the shifting part 8 of pedestal 7 one sides is subjected to the elastic force influence of flexible member 81, and fasten tooth portion 41 in the revolving part 4,4 of revolving parts are not subjected to the torsion influence of torsion spring 5 and maintain on the angle after the rotation, just make dust removing cloth 9 remain on the state of spiral, and when cleaning needs to change or take off dust removing cloth 9 later, the user only needs shifting part 8 mobile in the other direction with external force, after making shifting part 8 leave the tooth portion 41 of revolving part 4, revolving part 4 is subjected to the torsion counter-rotating of torsion spring 5 immediately and gets back to initial angle position, this moment, dust removing cloth 9 also returned to smooth state, and reached the purpose that dust removing cloth 9 is changed so as to dust removing cloth 9 and revolving part 4 are unclamped.

In addition, whirligig 2 can be connected with the link A2 of a flexible body of rod A1 by the fixed part 73 of pedestal 7 one sides, make whirligig 2 can pass through the Telescopic of flexible body of rod A1, to carry out the cleaning action of differing heights and distance, and mainly be that a press section A3 with two above fixture block A31 is set on the link A2, when needs are adjusted the angle of whirligig 2 on flexible body of rod A1, forcing in press section A3 by opposite side makes fixture block A31 on it leave the internal tooth 731 of fixed part 73, be not subjected at internal tooth 731 under the restriction of fixture block A31, can adjust the angle of whirligig 2 voluntarily, and after adjusting angle, force in press section A3 simultaneously, make the fixture block A31 on it enter and be embedded in the internal tooth 731, therefore limit under the situation of internal tooth 731 at fixture block A31, whirligig 2 can't be adjusted, and promptly remains on this angle.

Whirligig 2 of the present utility model except being needed directly to adjust the dust removing cloth with hand to solve known anchor clamps by revolving part 4 Rotary dust collecting cloth 9, when needs are changed or are taken off dust removing cloth 9, and can make the revolving part 4 auto-reverse dust removing cloth 9 that make be returned to smooth state by reverse mobile shifting part 8, can directly take off dust removing cloth 9 for the user.

Comprehensively above-mentioned, more than be a preferred embodiment of the present utility model, be not in order to limiting to protection domain of the present utility model, protection domain of the present utility model must be as the criterion with the defined scope of aforementioned claim.
