Abstract
The utility model discloses a rotary device for a rotary mop, comprising a rotary barrel and a rotary shaft, wherein the rotary barrel is provided with an internal thread; the rotary shaft comprises a rotary head, a unidirectional rotary block and a reset spring; a lug is disposed on the rotary head and matched with the internal thread; the internal thread is a rectangular thread, and the lead angle thereof is optimized; and the lead angle of the internal thread is the optimal. The rotary device for a rotary mop disclosed by the utility model has the advantages of reasonable spiral appearance, easy utilization of mop, scientific lead angle, as well as fast whirling and cleaning speeds; and the rotary device for a rotary mop can obtain a large rotary torque.
Description
Technical field
The utility model relates to the mop technical field, especially relates to a kind of whirligig of rotary mop.
Background technology
Rotary mop is widely-used at present, and its whirligig is for realizing the main device of mophead rotation.General, the whirligig of this rotary mop comprises rotating cylinder and rotating shaft.Wherein, rotating cylinder is provided with internal thread, and rotating shaft comprises swivel head, unidirectional spill spin block and back-moving spring.Simultaneously, swivel head is provided with projection, and projection and internal thread match.Mophead is installed in the bottom of rotating shaft.During use, through pressing down rotating cylinder repeatedly, the internal thread in the rotating cylinder acts on projection, the rotation of projection driven rotary axle, thus drive the mophead rotation, reach the purpose that cleans and dry mophead.But, because the spiral shell shape and the lead angle of the internal thread in the rotating cylinder are unreasonable, cause the rotary speed of rotating shaft or rotation torque unreasonable, use very inconvenience.Therefore be necessary the whirligig of rotary mop is improved.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of whirligig of rotary mop, and it is reasonable that it has spiral shell shape, and the lead angle science makes that rotary mop uses easily, characteristics easily.
To achieve these goals; The technical scheme that the utility model adopted is: the whirligig of rotary mop; Comprise rotating cylinder, rotating shaft; Wherein, Rotating cylinder is provided with internal thread; Rotating shaft comprises swivel head, unidirectional spill spin block and back-moving spring, and swivel head is provided with projection, and projection and internal thread match; Said internal thread is a rectangular thread, and its lead angle
is
The internal threads l angle
is
The internal threads l angle
is
After adopting said structure, the utility model is compared the advantage that is had with prior art and is: 1, spiral shell shape is reasonable, and mop uses easily.The spiral shell shape of internal thread is taked rectangle, makes the slip of projection in internal thread derailing can not occur, skid and phenomenon such as not smooth, has realized internal thread and projection better fit.2, lead angle science, drying and cleaning speed are fast, and can access bigger rotation torque.Lead angle is through after optimizing, and for less lead angle, it is too slow rotation can not occur, and the situation of very requiring great effort when pressing down rotating cylinder.For bigger lead angle, the not enough situation of rotation torque can not appear.That is, realized that the user presses down dynamics, rotating shaft rotary speed, three aspects such as rotation torque that obtain organic balanced, make the user extremely easy to use.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the perspective view (broken section) of the utility model embodiment.
The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see shown in Figure 1: the whirligig of rotary mop, comprise rotating cylinder 1, rotating shaft 2, wherein, rotating cylinder 1 is provided with internal thread 11, and rotating shaft 2 comprises swivel head 21, unidirectional spill spin block 23 and back-moving spring 22.Swivel head 21 is provided with projection 211, and projection 211 matches with internal thread 11.That is, projection 211 slides in internal thread 11.Internal thread 11 is taked rectangular thread; Its lead angle
is that
optimizes; The lead angle of internal thread 11
is
further to be optimized, and the lead angle of internal thread 11
is
The whirligig of rotary mop is widely-used at present, and other structure is identical with prior art with principle, repeats no more here.
