Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a retractable support leg structure and a tower fan. Background Technology

[0002] A tower fan is a type of floor fan that has the air blowing function of a regular fan, and can also have a heater function by installing an internal heater.

[0003] The tower fans on the market, such as the one described in utility model patent CN218325490U, have their main body's base support feet fixed by screws. If the main body of the tower fan needs to be installed on the pole, the support feet must be removed, which is a rather cumbersome operation. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a retractable support leg structure and a tower fan, which allows for simultaneous retraction of each support leg for easy installation on the upright.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model provides a retractable support foot structure, including a limiting plate, a rotatable turntable, and multiple radially retractable support feet; the turntable is rotatably disposed relative to the limiting plate; each support foot has a support portion, a push rod portion, and a slider portion connecting the support portion and the push rod portion; the limiting plate is provided with multiple limiting grooves extending radially therefrom and cooperating with the slider portions, and the slider portions are slidably assembled into corresponding limiting grooves; the turntable is provided with multiple guide grooves cooperating with the push rod portions, and the push rod portions are movably assembled into corresponding guide grooves; when the turntable is rotated, the inner wall of each guide groove pushes the corresponding push rod portion to slide back and forth within it, and the movement trajectory of the slider portion is restricted by the corresponding limiting groove, so that each support portion expands or retracts along the radial direction of the limiting plate.

[0007] Furthermore, the limiting groove is in the shape of a straight line, and multiple limiting grooves are arranged at equal intervals around the central axis of the limiting plate.

[0008] Furthermore, the limiting slide groove has two side openings and a bottom opening facing different directions. The slider part can move through the side opening and slide into the limiting slide groove. The end of the push rod part facing away from the guide groove passes through the bottom opening with a clearance fit and is connected to the slider part.

[0009] Furthermore, the guide groove is arc-shaped; one end of the guide groove in its extending direction is close to the outer edge of the turntable, and the other end is close to the central axis of the turntable; multiple guide grooves are equally spaced around the central axis of the turntable.

[0010] Furthermore, a limiting component is provided between the turntable and the limiting plate. The limiting component is used to limit the maximum distance between the turntable and the limiting plate to ensure that the push rod can slide stably on the corresponding guide groove.

[0011] Furthermore, the limiting component includes multiple limiting pins and limiting windows that cooperate with the limiting pins. The turntable is provided with a limiting window near its outer edge. The rod of the limiting pin is movably inserted through the limiting window and connected to the limiting plate. The outer diameter of the head of the limiting pin is larger than the inner diameter of the limiting window, so that the head can slide against the side of the turntable away from the limiting plate.

[0012] Furthermore, the extension length of the limiting window matches the extension length of the guide groove.

[0013] This utility model provides a tower fan, which includes at least the above-mentioned retractable support leg structure.

[0014] The technical solution provided by this utility model has the following beneficial effects:

[0015] When the turntable is rotated in the forward and reverse directions, the inner walls of each guide groove on the turntable push the corresponding push rod to slide back and forth within it, and the movement trajectory of the slider is restricted by the corresponding limiting groove. Therefore, through the joint cooperation of the limiting plate, the turntable, and the push rod and slider of the support foot, the support part of each support foot can be unfolded or retracted along the radial direction of the limiting plate. When each support foot retracts synchronously, it is also convenient to install it on the upright. Attached Figure Description

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 5 This embodiment provides a tower fan, including a pole 300, a tower fan body 200, and a retractable support leg structure (hereinafter referred to as the support leg structure 100). The tower fan body 200 is installed in a mounting groove at the top of the pole 300 via the support leg structure 100. Of course, in other embodiments, the support leg structure 100 of this embodiment can also be adapted to equipment with a large chassis anti-tipping structure, such as desktop household appliances.

[0024] like Figure 2 and Figure 3 As shown, the support foot structure 100 of this embodiment includes a limiting plate 1, a rotatable turntable 2, and four radially retractable support feet 3. The limiting plate 1 is the base of the tower fan body 200 and is fixed. The turntable 2 is rotatably arranged relative to the limiting plate 1. Each support foot 3 has a support part 31, a push rod part 32, and a slider part 33 connecting the support part 31 and the push rod part 32.

[0025] like Figures 3 to 5 As shown, the limiting disk 1 is provided with four limiting grooves 11 extending radially and cooperating with the slider part 33. Each slider part 33 is slidably assembled in its corresponding limiting groove 11. Specifically, each limiting groove 11 is in the shape of a straight line. The four limiting grooves 11 are equally spaced around the central axis of the limiting disk 1. Each limiting groove 11 has two side openings 111 and a lower opening 112 facing different directions. Each slider part 33 can move through the side opening 111 and be slidably inserted into its corresponding limiting groove 11. The upper end of the push rod part 32 passes through the lower opening 112 with a clearance fit and is connected to the corresponding slider part 33.

[0026] like Figures 2 to 4As shown, the turntable 2 is provided with four guide grooves 21 that are equally spaced around the central axis of the turntable 2 and cooperate with the push rod part 32. The lower end of each push rod part 32 is movably assembled into the corresponding guide groove 21. Specifically, each guide groove 21 is arc-shaped, and the outward end of each guide groove 21 in its extension direction is close to the outer edge of the turntable 2, and the inward end is close to the central axis of the turntable 2, so as to ensure that each push rod part 32 moves accordingly under the push of the inner groove wall of the guide groove 21, thereby driving the slider part 33 and the support part 31 to move synchronously, that is, to realize the synchronous radial expansion (i.e., opening) or retraction (i.e., folding up) of each support foot 3.

[0027] When using the tower fan, the turntable 2 can be rotated in both directions to synchronously extend or retract each support leg 3.

[0028] When the support legs 3 are deployed simultaneously, the support portions 31 of each support leg 3 together form a chassis with a significantly larger support area. This facilitates the use of the tower fan body 200 standing upright on a table or the ground via the support leg structure 100, and also prevents the tower fan body 200 from tipping over. Of course, one can also pull the support portion 31 of one of the support legs 3 by hand, or the other support legs 3 can be deployed or retracted in conjunction.

[0029] like Figure 1 and Figure 2 As shown, when the support legs 3 retract synchronously, the two ends of each support part 31 abut against each other in the circumferential direction and no longer exceed the outer periphery of the limit plate 1, so that it is easy to install it in the mounting groove at the top of the pole 300. At this time, the pole 300 adopts a liftable and lowerable structure to freely adjust the usage height of the tower fan body 200, thus making it suitable for different application scenarios.

[0030] Of course, in other embodiments, the number of support feet 3, limiting slide grooves 11 and guide grooves 21 is not limited to this, and can also be 2, 3 or other numbers.

[0031] Further preferred, such as Figures 2 to 4 As shown, a limiting component is provided between the turntable 2 and the limiting plate 1. The specific limiting component includes four limiting pins 12 and four limiting windows 23 that cooperate with the limiting pins 12. The turntable 2 is provided with a limiting window 23 near its outer edge, and the extension length of the limiting window 23 matches the extension length of the guide groove 21 to ensure that the support part 31 of each support leg 3 can achieve a sufficiently long extension distance.

[0032] The rod of each limiting pin 12 is movably inserted through the corresponding limiting window 23 and connected to the limiting plate 1. The outer diameter of the head of the limiting pin 12 is larger than the inner diameter of the limiting window 23, so that the head of the limiting pin 12 can slide against the bottom side of the turntable 2 away from the limiting plate 1. This can limit the maximum distance between the turntable 2 and the limiting plate 1 within a reasonable range, so as to ensure that each push rod part 32 can slide stably on the corresponding guide groove 21.

[0033] Of course, in other embodiments, the limiting pin 12 can also be mounted on the turntable 2, and the limiting window 23 is set on the limiting plate 1, so that each push rod part 32 can slide stably on the corresponding guide groove 21.

[0034] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
