Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, embodiments of the present utility model will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be arbitrarily combined with each other.

As shown in fig. 1 to 5, the fan with openable and closable legs according to the present utility model is shown, comprising at least two openable and closable legs 4, and further comprising an upper leg cover plate 1 and a lower leg cover plate 3 which are cooperatively connected with each other, the top ends of the legs 4 being installed between the upper leg cover plate 1 and the lower leg cover plate 3 through a rotation shaft 7. The rotating shaft of the utility model can be integrally arranged at the top ends of the supporting legs, and can also be detachably arranged at the top ends of the supporting legs or on the upper cover plate or the lower cover plate of the supporting legs. The support legs can rotate relative to the installation part through the rotating shaft, and the support legs can be conveniently opened and closed. More specifically, the lower leg cover plate 3 and the upper leg cover plate 1 are connected by a fixing member such as a bolt, and the main body structure of the fan is provided on the upper leg cover plate 1. When the support leg is detached, the support leg can be detached only by detaching the support leg lower cover plate from the support leg upper cover plate. When in use, the support legs are separated and supported on the using platform; when in storage, the support legs can be directly closed to form a cylinder shape, and the disassembly and the installation are very convenient.

As shown in fig. 1-3, the lower cover plate 3 of the support leg is provided with a notch part 8, the upper cover plate 1 of the support leg is provided with a notch part 10 corresponding to the notch part 8, and the notch part 8 and the notch part 10 are matched to form an installation space of the rotating shaft. The lower leg cover 3 is provided with a groove 80 at the position of the notch 8, the end of the rotation shaft 7 is provided with a mounting part 70, and the mounting part 70 can be accommodated in the groove 80 and is in rolling contact with the groove 80. In order to avoid abrasion or noise caused by friction between the mounting portion and the groove, a damping member 2 may be provided between the mounting portion and the groove, and the damping member 2 may take the form of an elastic ring or an elastic pad. Like this, compress tightly the back at upper cover plate and lower cover plate, form the extrusion between damping piece and the stabilizer blade rotation axis for the stabilizer blade position is comparatively firm. When the support leg is rotated, the support leg can not be rapidly closed and generate noise, and the problems that the noise is generated when the support leg is folded, the body feeling is affected, and the rebound is generated after the support leg is folded are solved. Preferably, in order to enhance the collapsing force between the legs, to avoid the problem of random shaking and collision of the legs due to the insufficient collapsing force, protrusions 6 and a sinking table 5 may be provided at the sides of the legs. When the support legs are folded, adjacent support legs can be mutually matched and pressed through the protrusions and the sinking tables, so that the binding force between the two support legs is enhanced.

Although the embodiments of the present utility model are described above, the embodiments are only used for facilitating understanding of the present utility model, and are not intended to limit the present utility model. Any person skilled in the art can make any modification and variation in form and detail without departing from the spirit and scope of the present disclosure, but the scope of the present disclosure is still subject to the scope of the appended claims.
