Embodiment

Describe the utility model in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that do not rushing In the case of prominent, the feature in embodiment and embodiment in the application can be mutually combined.

A kind of clothing care machine is present embodiments provided, can be washing machine, dryer etc., also can be with the other of rotating shaft Machine.

Fig. 1 is the structural representation of clothing care machine, and Fig. 2 is the scheme of installation (one) of wavy spring, and Fig. 3 is waveform bullet The scheme of installation (two) of spring, Fig. 4 are the assembling schematic diagrams of wavy spring, as shown in Figure 1, Figure 2, Figure 3 and Figure 4：

The clothing care machine 10 has body 6, roller 7 and the (not shown) of motor 8, and motor 8 is driven by rotating shaft 5 and rolled Cylinder 7, rotating shaft 5 are provided with two grooves 91, and 92, and a kind of wavy spring 1 of rotating shaft 5 for the clothing care machine 10.Should Wavy spring 1 includes the first spring body 2 and second spring body 3, it is preferred to use elastic metallic material is made, and specifically such as passes through punching press Mode is made.

A pair of grabs are respectively equipped with the both ends of first spring body 2 and second spring body 3, it is recessed in rotating shaft 5 with being arranged on The clamping of groove 91,92.Specifically, the both ends 21,22 of the first spring body 2 are provided with grab 41,42, the both ends 31,32 of second spring body It is connected to provided with grab 43,44, wherein grab 41,43 on groove 91, grab 42,44 is connected on groove 92.

By the way that wavy spring 1 is divided into two parts, it is respectively installed in rotating shaft 5, wavy spring 1 can be ensured by crowded During pressure, uniform force.Simultaneously because wavy spring 1 is snapped fit onto in rotating shaft 5, when axle rotates, can prevent wavy spring and The relative motion of rotating shaft 5, effectively avoid the friction of wavy spring and neighbouring parts (such as bearing 11 or axle sleeve 12).

Specifically, as shown in figure 4, in assembling, the first spring body 2 and second spring body 3 are respectively from the section two of rotating shaft 5 Side is detachably mounted in rotating shaft 5.By mechanical arm 20, i.e., the installation of wavy spring can be realized, without artificial, and When wavy spring needs to change, it is not necessary to dismantle axle sleeve 11, bearing 12 etc., directly complete dismounting more by mechanical arm 20 Change.

Fig. 5 A are the perspective view of wavy spring in the axial direction, and Fig. 5 B are the schematic diagram of wavy spring in the axial direction, such as Shown in Fig. 5 B, the first spring body 2 and second spring body 3 structure in wave shape on axial X, there is crest and trough.Such as Fig. 5 A institutes Show, the axial X projections of the first spring body 2 and second spring body 3 are in half ring shape.

Fig. 6 A are the schematic diagrames of rotating shaft, and Fig. 6 B are the schematic cross-sections of rotating shaft, as shown in Figure 6 A and 6B, preferably, on The hole slot that groove 91,92 is arranged to square is stated, is easy to the grab 41,42,43,44 of the first spring body 7 and second spring body 8 solid It is scheduled in groove 91,92, can ensures that wavy spring is fixed in rotating shaft and will not shifted.

By the utility model, solve the problems, such as wavy spring generation in the prior art and the relative motion of axle, can The relative motion of wavy spring and rotating shaft is prevented, ensures wavy spring when being squeezed, uniform force, so as to ensure that machine is transported More steady during row, noise is smaller, abrasion lightens, and and can ensures facility when installation and maintenance, greatly simplifies assembling work Skill.

Various embodiments described above and shown in the drawings are merely to illustrate the utility model, not this reality With new whole.In the category of basic fundamental thought of the present utility model, those of ordinary skill's pin of correlative technology field Any type of change carried out to the utility model is within the scope of protection of the utility model.
