Description

Rotating mechanism of household appliance

Technical Field

The utility model relates to a household appliance rotating mechanism, which is mainly used for household appliances such as fan heaters, electric fans, air purifiers and the like which need to rotate in the direction.

Background

At present, household appliances such as an electric fan, a fan heater and the like have the function of shaking the head, but because the main structures of the rotating base and the household appliances such as the electric fan, the fan heater and the like are in hard connection, if the rotating angle is too large during rotation, the rotating base and the main bodies of the household appliances can be broken, so that the shaking and rotating angle is limited, and the use requirements of people cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome foretell not enough, provide a domestic appliance rotary mechanism that turned angle is bigger.

The technical scheme of the utility model as follows:

the utility model provides a household appliance rotary mechanism, includes internal gear and annular outer gear, and the internal gear is in the outer gear, the internal gear includes mount pad and two piece at least racks, and rack evenly distributed is around the mount pad, and every rack all is connected with the mount pad through a set of shock attenuation strip, and the outer gear inner ring is equipped with the internal tooth, and the rack outside is equipped with the external tooth, and internal tooth and external tooth meshing.

Preferably, the number of the racks is two, and the racks are symmetrically arranged on two sides of the mounting seat.

Preferably, the shock-absorbing strips are S-shaped, two shock-absorbing strips are arranged in each group, the inner ends of the shock-absorbing strips are connected with the mounting seat, and the outer ends of the shock-absorbing strips are connected with the corresponding racks.

Preferably, the mounting base is further provided with a non-circular hole, and the non-circular hole is located at the center of the outer gear. The non-circular hole can be, but is not limited to, a triangular hole and a square hole, and after the household appliance body is installed in the hole, the rotating mechanism can drive the household appliance body to rotate.

Preferably, at least one positioning strip is further protruded on the outer edge of the outer gear.

Preferably, the number of the positioning strips is at least two, and the positioning strips are uniformly distributed on the outer edge of the outer gear.

The utility model has the advantages that:

the utility model discloses in the rack external tooth through the internal gear and the internal gearing of external gear, make internal gear and external gear can the transmission each other, and the rack passes through S-shaped shock attenuation strip and is connected with the mount pad, has played the effect of shock attenuation buffering, makes and installs in 360 free rotations of household electrical appliances main body physical stamina of internal gear mount pad, and difficult emergence fracture.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a perspective view of the present invention;

fig. 2 is a top view of the present invention;

fig. 3 is a schematic view of the present invention installed on a base of a household appliance.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to be referred must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be construed broadly, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The household appliance rotating mechanism shown in fig. 1 and 2 comprises an internal gear 1 and an annular external gear 2, wherein the internal gear 1 is arranged in the external gear 2, the internal gear 1 comprises a mounting seat 11 and two racks 12, the racks 12 are symmetrically arranged on two sides of the mounting seat 11, each rack 12 is connected with the mounting seat 11 through a group of shock-absorbing strips 13, each group of shock-absorbing strips 13 is provided with two shock-absorbing strips 13, the shock-absorbing strips are S-shaped, the inner ends of the shock-absorbing strips 13 are connected with the mounting seat 11, and the outer ends of the shock-absorbing strips are connected with the corresponding. The external gear 2 is internally provided with internal teeth 21 at the inner ring thereof, and is externally provided with external teeth 14 at the outer side of the rack 12, and the internal teeth 21 are engaged with the external teeth 14. The mounting seat 11 is further provided with a noncircular hole 3, and the noncircular hole 3 is located at the center of the outer gear 2. The non-circular hole can be, but is not limited to, a triangular hole and a square hole, and after the household appliance body is installed in the hole, the rotating mechanism can drive the household appliance body to rotate. Due to the split design of the inner gear and the outer gear, and the S-shaped damping strip in the inner gear can play a damping and buffering role, the household appliance main body can freely rotate within 360 degrees without burden.

Two symmetrical positioning strips 4 are also projected on the outer edge of the outer gear 2, and the outer gear is clamped on a base (shown in figure 3) or a stand column of the household appliance through the positioning strips.

In light of the above, the present invention is not limited to the above embodiments, and various changes and modifications can be made by the worker without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
