Description

Fan activity stand

This creation is about a fan movable tripod, especially a fan movable tripod structure that is easier to assemble, saves labor, and has a stable opening and folding position.

According to the industrial fan, the torque of the motor is large, so the supporting area of the supporting tripod must be increased to prevent the center of gravity from falling. The conventional tripods are mainly arranged in a radial arrangement. In order to enable the tripod to be folded when the fan is not in use, in the manufacture, the top of the support leg of the tripod and the base are pivotally connected by a pivoting device. So that the support legs can be folded in the middle when the fan is not in use. The conventional pivoting device is not pivoted by a screw or pivoted by a rivet, such as the Taiwan certificate number M406105 created by the creator and the Taiwan certificate numbers M497202 and M473443 created by others. The conventional pivoting device is not only labor-intensive and time-consuming to assemble, but also relatively increases the manufacturing cost. It is also known that the support feet cannot achieve the correct positioning effect after folding and opening, and there is still room for improvement.

In response to the above shortcomings, the creator has intensively conceived R&D creations, and after a long period of hard work, he has created this creation.

Therefore, the main purpose of this creation is to provide a fan-moving tripod that saves assembly time and reduces manufacturing costs.

Another creative purpose of this creation is to provide a fan movable stand that can be positioned and stabilized in a folded or open state.

In order to achieve the above object, the main feature of the present invention is that at least a pair of elastic plates extending from the inner wall of the insertion sleeve portion are disposed inside the insertion sleeve portion, and the elastic plates are respectively provided with a convex particle at opposite ends thereof, and the convex portion is extended. The direction is perpendicular to the support leg, and the sidewall surface of the top end of the support leg is provided with a consistent hole corresponding to each of the convex positions, and the convex portion is radially embedded in the through hole; the anti-rotation body is disposed inside the insertion portion. The port at the top end of the support leg is axially cut with a notch corresponding to the position of the anti-rotation body, and the anti-rotation system is radially embedded in the slot, thereby achieving the advantages of simple assembly and labor saving.

Another feature of the present invention is that there are two corresponding inner walls in the middle portion of the inner portion of the insertion sleeve portion, and a protrusion is protruded in the middle direction, and a narrow opening is formed between the two protrusions, and the inner wall of the narrow opening is plastic. The support leg is displaced; the inside of the insert portion is bounded by the narrow opening, and a closed receiving space for the support leg is separated from the open end, and the other end is separated by a support leg. The accommodating opening space for positioning, the inner space of the folding accommodating space and the opening accommodating space is equivalent to the outer diameter of the supporting leg, whereby the supporting foot can be positioned and stabilized in the folded or opened state .
