Detailed Embodiment

[0015] For the convenience of understanding the utility model, the utility model will be described more comprehensively below with reference to the attached drawings. The preferred embodiments of the utility model are given in the drawings. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0016] See the attached Figures 1 - 3As shown, in this embodiment, a multi-gear folding drying rack includes two columns 1, two groups of support components 2 respectively arranged on the two columns 1, and a group of cross components 3. Among them, each group of support components 2 includes a fixed seat 22 fixed to the bottom end of the column 1, a support sliding seat 21 slidably sleeved on the column 1, three groups of support connecting rods 24, and three legs 23 all pivotally connected to the support sliding seat 21. The two ends of each group of support connecting rods 24 are respectively hinged to the fixed seat 22 and a leg 23. Each group of support connecting rods 24 is composed of two parallel rod bodies. Specifically, a sliding through hole with a diameter slightly larger than the diameter of the column 1 is formed in the middle of the support sliding seat 21 to facilitate the axial sliding of the support sliding seat 21 along the column 1; a fixed groove with a diameter equal to or slightly smaller than the diameter of the column 1 is formed in the middle of the fixed seat 22 to facilitate the relative interference nesting fit between the bottom end of the column 1 and the fixed groove of the fixed seat 22 (in actual products, in order to avoid detachment, additional reinforcement methods such as screws can be used, which is not specifically limited here); the upper end of the leg 23 is pivotally connected to the support sliding seat 21 through a preset first pin shaft, and both ends of the support connecting rod 24 are pivotally connected to the fixed seat 22 and the middle and lower parts of the leg 23 through preset second pin shafts. Therefore, the column 1, the support connecting rod 24, and the leg 23 cooperate with the support sliding seat 21 to form a sliding link mechanism. By moving the support sliding seat 21 up or down along the column 1, the three legs 23 in the same group are correspondingly retracted and folded or outwardly supported and unfolded, that is: when the support sliding seat 21 moves up along the column 1, it correspondingly drives the three legs 23 to rotate inward around their respective first pin shafts to achieve the effect of retraction and folding; conversely, when the support sliding seat 21 moves down along the column 1, it correspondingly drives the three legs 23 to rotate outward around their respective first pin shafts to achieve the effect of outward support and unfolding.

[0017] In this embodiment, the cross member 3 includes a pair of cross bars 31 pivotally connected in a cross shape, two cross sliding seats 32 respectively sleeved on the two columns 1 in a sliding manner, and two linkage rods 33 respectively corresponding to the two cross bars 31 one by one. Among them, both ends of each cross bar 31 are respectively pivotally connected to the fixed seats 22 and the cross sliding seats 32 on the two columns 1; both ends of each linkage rod 33 are respectively pivotally connected to the cross bar 31 and the support sliding seat 21. Specifically, a sliding through hole with a diameter slightly larger than the diameter of the column 1 is formed in the middle of the cross sliding seat 32 to facilitate the cross sliding seat 32 to axially slide along the column 1; the two cross bars 31 are pivotally connected by a preset third pin shaft, and the lower end of the cross bar 31 and the fixed seat 22 are pivotally connected by a preset fifth pin shaft. Therefore, the two columns 1 realize the approach or separation of the two columns 1 in the horizontal direction by means of a sliding link mechanism composed of a pair of cross bars 31 and cross sliding seats 32, that is, when the cross sliding seat 32 moves downward along the column 1, it correspondingly drives the cross bar 31 to turn and approach to make the two columns 1 separate in the horizontal direction; conversely, when the cross sliding seat 32 moves upward along the column 1, it correspondingly drives the cross bar 31 to turn and open to make the two columns 1 approach in the horizontal direction.

[0018] Further, both ends of each linkage rod 33 are respectively pivotally connected to the cross bar 31 and the support sliding seat 21. Among them, the upper end of the cross bar 31 and the cross sliding seat 32 are pivotally connected by a preset fourth pin shaft. Specifically, the cross bar 31 and the support sliding seat 21 realize the linkage cooperation between the contraction and folding or outward expansion of the leg 23 and the approach or separation of the column 1 through the pivotal connection structure of the linkage rod 33, that is: when the leg 23 makes contraction and folding, correspondingly, the column 1 makes approach; conversely, when the leg 23 makes outward expansion, correspondingly, the column 1 makes separation. By adopting this linkage method, the steps of folding or unfolding operations can be reduced, and it is more simple and easy to operate.

[0019] In this embodiment, a guide hole extending along the length direction of one end of the linkage rod 33 and slidably hinged to the cross bar 31 is formed, that is: the guide hole is for the sliding fit of the fourth pin shaft between the linkage rod 33 and the cross bar 31.

[0020] In this embodiment, it includes two telescopic sleeve rods 4 respectively slidably nested in the two columns 1, that is: the column 1 is a hollow tubular structure, and the telescopic sleeve rod 4 is correspondingly slidably nested in the inner cavity of the column 1 to facilitate the telescopic sleeve rod 4 to relatively adjust the height with respect to the column 1; secondly, the column 1 can be provided with a plurality of vertically arranged positioning holes, so that an elastic positioning buckle (the specific structure of the elastic positioning buckle and the elastic cooperation method with the positioning hole belong to conventional technical means and will not be elaborated here) that can be elastically matched with the positioning holes is added between the column 1 and the telescopic sleeve rod 4.

[0021] In this embodiment, it further includes a drying rod 5, a flipping sliding sleeve 6 slidably sleeved on the drying rod 5, and a fixed clamping sleeve 7. Among them, the flipping sliding sleeve 6 is pivotally connected to the top of one of the telescopic sleeve rods 4 (since the telescopic sleeve rod 4 is generally made of a metal pipe fitting, a plastic part needs to be sleeved on the top of the telescopic sleeve rod 4 so that the flipping sliding sleeve can be pivotally connected to the plastic part, thereby realizing the rotational cooperation between the flipping sliding sleeve 6 and the telescopic sleeve rod 4). The fixed clamping sleeve 7 is fixedly nested on the top of the other telescopic sleeve rod 4, and the drying rod 5 can be flip-clamped or flip-unlatched with the fixed clamping sleeve 7. Specifically, the flipping sliding sleeve 6 and the top of the telescopic sleeve rod 4 can be pivotally connected through a preset sixth pin shaft, so that the flipping sliding sleeve 6 can be turned up or down relative to the telescopic sleeve rod 4 around the sixth pin shaft; the flipping sliding sleeve 6 is formed with a sliding through hole whose diameter width is slightly larger than the diameter width of the drying rod 5 to facilitate the flipping sliding sleeve 6 to axially slide relative to the drying rod 5, and the drying rod 5 turns up or down synchronously with the flipping sliding sleeve 6; the fixed clamping sleeve 7 is formed with an arc-shaped bayonet for the drying rod 5 to be clamped, so that the drying rod 5 can be flipped and slid to the fixed clamping sleeve 7 to be clamped with the arc-shaped bayonet, achieving the effect of flip-clamping; conversely, when storage is needed, the drying rod 5 can be flipped to disengage from the arc-shaped bayonet to achieve the effect of flip-unlatching. In this way, the drying rod 5 can adapt to the two columns 1 with different pre-adjusted horizontal spacings, being more flexible and variable.

[0022] In this embodiment, the cross sliding seats 32 on the same column 1 are located above the support sliding seat 21.

[0023] The design of this multi-gear folding drying rack not only has a flexible adjustment function but also realizes the simplicity of operation through a linkage mechanism. Specifically, the drying rack adopts a combined design of two columns 1, a support assembly 2, and a cross assembly 3, enabling the drying rack to remain stable during folding and unfolding. The support slide 21, support link 24, and leg 23 in the support assembly 2 form a sliding link mechanism, allowing the leg 23 to be retracted and folded or extended outward as needed. The cross assembly 3 realizes the inward closing or outward expansion of the two columns 1 in the horizontal direction through the cross bar 31 and cross slide 32. The design of the linkage rod 33 enables the linkage between the folding / expansion of the leg 23 and the closing / expansion of the column 1. This design reduces the operation steps and improves the usability. Users can simultaneously achieve multiple functions of the drying rack by operating only one mechanism, greatly improving the efficiency. The design of the telescopic sleeve rod 4 enables the height of the drying rack to be adjusted as needed. This design allows the drying rack to adapt to different usage scenarios and increases its applicable range. The drying rod 5 can be connected to the telescopic sleeve rod 4 through the flipping slide sleeve 6 and fixed clamping sleeve 7, realizing the flipping clamping or flipping release of the drying rod 5. This design enables the drying rod 5 to be easily installed and disassembled, and is also convenient for storage and transportation. Through the positioning holes and elastic positioning buttons on the column 1, the drying rack can achieve multi-gear adjustment. Users can select the appropriate gear according to their needs to meet different usage requirements.

[0024] In summary, this multi-gear folding drying rack has the characteristics of reasonable structural design, simple operation, adjustable height, good stability, and strong durability. It can not only meet the basic drying needs of users but also be flexibly adjusted according to different usage scenarios, improving the usability and comfort.
