Description

Technical Field

[0001] The utility model relates to the technical field of fan brackets, in particular to a floor-standing bracket structure for a fan. Background Art

[0002] Prior art, such as the Chinese utility model patent document with publication number CN212250559U, discloses a fan support stand, including a mounting base and a support leg, at least three support legs are provided, a mounting groove with an open bottom is provided on the side of the mounting base, one end of the support leg is provided in the mounting groove, a connecting piece is provided in the mounting groove, connecting holes are provided on both sides of the connecting piece, the support leg is provided with a through hole corresponding to the position of the connecting hole, a connecting shaft passes through the connecting hole and the through hole, and the support leg is rotatably connected to the mounting base.

[0003] Based on the above, in the prior art, this angle limit structure is achieved by a fixed bolt and a limit block. However, the technical problem with this type of angle limit structure is that the limit is not completely locked. When either the support leg or the connecting member is subjected to a force, the fixed bolt and the limit block may separate. In this case, the support leg and the connecting member will rotate relative to each other, making the limit impossible. The limit stability is poor and needs further improvement. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a floor-standing bracket structure for a fan.

[0005] A floor-standing stand structure for a fan designed for this purpose includes a mounting member connected to the fan, the mounting member being provided with a plurality of connecting members, the connecting members being hingedly connected to a foot rod, the foot rod being provided with a locking assembly that is mutually locked with the connecting members, the locking assembly including an elastic element provided on the foot rod, and the connecting members being provided with a positioning hole;

[0006] The elastic element is configured such that when the foot rod is in an unfolded state, the elastic element is inserted into the positioning hole to restrict the foot rod from rotating relative to the connecting member.

[0007] Preferably, the foot rod is provided with a mounting hole interconnected with the positioning hole, the elastic element includes a positioning pin movably arranged in the mounting hole, and the positioning pin and the foot rod are connected by an elastic member;

[0008] The elastic member is configured as follows: the elastic member applies a force to the positioning pin, so that the positioning pin remains inserted into the positioning hole.

[0009] Preferably, the mounting member is a sleeve with an open upper end, the sleeve is threadedly connected to a locking bolt, and the axis of the locking bolt and the axis of the sleeve are arranged perpendicular to each other.

[0010] Preferably, there are three connecting members and they are arranged along the circumference of the mounting member.

[0011] Compared to the prior art, the locking assembly of the present invention includes an elastic element disposed on the foot rod, and a positioning hole is provided on the connecting member. The elastic element is configured so that when the foot rod is in the extended state, the elastic element is inserted into the positioning hole to restrict the foot rod from rotating relative to the connecting member. The present invention uses the elastic element and the positioning hole to achieve a locking effect. When the foot rod needs to be rotated to adjust its angle, the elastic element needs to be pressed to disengage it from the positioning hole, which allows the foot rod to rotate relative to the connecting member. This results in a simple structure and good stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] See also Figure 1-Figure 4 A floor-standing stand structure for a fan includes a mounting member 110 connected to the fan, the mounting member 110 being provided with a plurality of connecting members 120, the connecting members 120 being hingedly connected to a foot rod 20, the foot rod 20 being provided with a locking assembly 30 that is mutually locked with the connecting member 120, the locking assembly 30 including an elastic element 300 provided on the foot rod 20, and the connecting member 120 being provided with a positioning hole 330;

[0018] The elastic element 300 is configured such that when the foot bar 20 is in the unfolded state, the elastic element 300 is inserted into the positioning hole 330 to restrict the foot bar 20 from rotating relative to the connecting member 120 .

[0019] Based on the above, the utility model adopts the elastic element and the positioning hole for plugging and locking. When the foot rod needs to be rotated to adjust the angle, it is necessary to press the elastic element to disengage it from the positioning hole before the foot rod can be driven to rotate relative to the connecting piece. The structure is simple and the stability is good.

[0020] See also Figure 3 The foot rod 20 is provided with a mounting hole 210 that is in communication with the positioning hole 330 , and the elastic element 300 includes a positioning pin 320 movably disposed in the mounting hole 210 , and the positioning pin 320 is connected to the foot rod 20 by an elastic member 310 ;

[0021] The elastic member 310 is configured to apply a force to the positioning pin 320 so that the positioning pin 320 remains inserted into the positioning hole 330 .

[0022] Furthermore, the elastic member 310 is a V-shaped spring piece.

[0023] When the limit constraint is released, the positioning pin 320 is pressed to move the positioning pin 320 inward until the positioning pin 320 exits the positioning hole 330, and the limit is released. During the movement of the positioning pin 320, the elastic member 310 is compressed to store force.

[0024] See also Figure 4 The mounting member 110 is a sleeve with an open top. A locking bolt 40 is threadedly connected to the sleeve, with the axis of the locking bolt 40 and the axis of the sleeve being perpendicular to each other. When assembling the fan with the stand, the fan's mounting rod is inserted into the sleeve. Then, by tightening the locking bolt 40 until it abuts against the mounting rod, assembly is complete.

[0025] In the present invention, three connecting members 120 are provided and arranged along the circumference of the mounting member 110 .
