Description

Technical Field

[0001] This utility model relates to the field of drying rack technology, and in particular to a linkage support frame and a drying device using the same. Background Technology

[0002] There are various types of floor-standing drying racks on the market. Structurally, they can be categorized as wing-shaped, X-shaped, single-pole, double-pole, and bi-fold. Considering people's needs for living space, most types have a folding function. Different structures and sizes result in different folding methods and styles after folding. The folding function, to varying degrees, affects the overall stability of the drying rack. In daily life, people's most important requirements for floor-standing drying racks are: 1. Stability; 2. Practicality and convenience; 3. Minimal space occupied when folded and stored. Furthermore, with the rapid development of e-commerce, ease of transportation is also a key factor considered in the structural design.

[0003] The X-shape, as a classic style of floor-standing clothes rack, has always held a certain market share in the clothes rack market.

[0004] As shown in Chinese invention patent publication number CN 108642819 A, existing X-shaped drying racks generally consist of a pair of X-shaped scissor frames and two horizontal drying rods. The load is entirely borne by the X-frames. When in use, the X-frames need to be unfolded, and the hanging clothes exert downward gravity on the horizontal drying rods. At this time, the upper rod of the X-frames is the main load-bearing component. Due to its inclined setting, its load-bearing capacity is limited. Therefore, there is still room for improvement in the stability and load-bearing performance of existing X-shaped drying racks. Utility Model Content

[0018] The first limiting mechanism includes a first limiting member disposed on the first rod and the third rod and cooperating with the first hinge seat;

[0019] The second limiting mechanism is a slide.

[0020] According to another aspect of the present invention, a drying device is also provided, including a pair of support frames and a horizontal drying rod disposed on the top of the support frames. The support frames are the linkage support frames as described above, and the top ends of the main rods corresponding to the pair of support frames are respectively connected by a horizontal drying rod.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a novel linkage support frame, which can be directly used as the main structure of an X-shaped floor-standing drying rack. The linkage support frame adds a linkage mechanism to the traditional scissor rack structure. This linkage mechanism realizes the linkage opening or closing through the movement of the scissor rack mechanism. When fully opened, the linkage rod can limit the main rod. More importantly, it can effectively increase the overall load-bearing capacity. When not in use, the scissor rack mechanism can drive the linkage mechanism to close, reducing space occupation.

[0035] Example 1

[0036] Figure 1-2 The diagram schematically illustrates a linkage support frame according to one embodiment of the present invention.

[0037] like Figure 1-2 As shown, the linkage support frame includes a scissor frame mechanism 1 and a linkage mechanism 2 movably connected to the scissor frame mechanism 1. The scissor frame mechanism 1 includes two main rods 11 hinged in the middle. The linkage mechanism 2 includes a linkage rod 21, and the two ends of the linkage rod 21 are movably connected to the two main rods 11 of the scissor frame mechanism 1, respectively.

[0038] The linkage 21 can change between being non-parallel to the main rod 11 and being parallel to the main rod 11;

[0039] When the linkage rod 21 is parallel to the main rod 11, the linkage rod 21 is located on the outer side of the main rod 11.

[0040] There are two linkage mechanisms 2, and the linkage rods 21 of the two linkage mechanisms 2 are respectively set on the outside of the two main rods 11.

[0041] The scissor mechanism 1 includes a first connecting member 12, a second connecting member 13, and a first hinge member 14. One main rod 11 includes a first rod body 111 and a second rod body 112, which are connected by the first connecting member 12. The other main rod 11 includes a third rod body 113 and a fourth rod body 114, which are connected by the second connecting member 13. The first connecting member 12 and the second connecting member 13 are movably connected by the first hinge member 14. The two ends of the linkage rod 21 of one linkage mechanism 2 are connected to the first rod body 111 and the fourth rod body 114, respectively. The two ends of the linkage rod 21 of the other linkage mechanism 2 are connected to the second rod body 112 and the third rod body 113, respectively.

[0042] The first connecting member 12 has first limiting holes at its upper and lower ends, which are respectively provided to limit the first rod 111 and the second rod 112. The second connecting member 13 has second limiting holes at its upper and lower ends, which are respectively provided to limit the third rod 113 and the fourth rod 114. Thus, the first connecting member 12, the first rod 111, and the second rod 112 are combined to form one main rod 11, and the second connecting member 13, the third rod 113, and the fourth rod 114 are combined to form the other main rod 11.

[0043] The linkage mechanism 2 also includes a first hinge seat 22 and a second hinge member 23. The first hinge seat 22 is installed on the first rod body 111 and the third rod body 113. The first end of the linkage rod 21 is movably connected to the first hinge seat 22 through the second hinge member 23.

[0044] The linkage mechanism 2 also includes a second hinge seat 24 and a third hinge member 25. The second hinge seat 24 is installed on the second rod body 112 and the fourth rod body 114. The second end of the linkage rod 21 is movably connected to the second hinge seat 24 through the second hinge member 23.

[0045] The linkage support frame of this embodiment also includes a first limiting mechanism 3 and a second limiting mechanism 4. The first limiting mechanism 3 is used to limit the first hinge seat 22, and the second limiting mechanism 4 is used to limit the second hinge seat 24.

[0047] The second limiting mechanism 4 includes a second limiting member 41 disposed on the second rod 112 and the fourth rod 114 and cooperating with the second hinge seat 24.

[0048] At least one of the first hinge seat 22 and the second hinge seat 24 needs to be able to slide onto the outer periphery of the main rod 1, that is, it is only necessary to ensure that the distance between the second hinge member 23 and the third hinge member 25 is adjustable.

[0049] Preferably, in this embodiment, the first hinge seat 22 is slidably fitted onto the outer periphery of the first rod 111 and the third rod 113 and located at the top of the linkage rod 21; the second hinge seat 24 is slidably fitted onto the outer periphery of the second rod 112 and the fourth rod 114 and located at the bottom of the linkage rod 21; the first limiting member 31 is located above the first hinge seat 22 and can limit the first hinge seat 22 and restrict its travel range; the second limiting member 41 is located below the second hinge seat 24 and can limit the second hinge seat 24 and restrict its travel range.

[0050] Preferably, the first limiting member 31 and the second limiting member 41 in this embodiment can be a columnar protrusion, a pin, a shaft, or an elastic member, etc.

[0051] This utility model provides a novel linkage support frame, which can be directly used as the main structure of an X-shaped floor-standing drying rack. The linkage support frame adds a linkage mechanism 2 to the traditional scissor rack structure. The linkage mechanism 2 realizes the linkage opening or closing through the movement of the scissor rack mechanism 1. When fully opened, the linkage rod 21 can limit the main rod 11. More importantly, it can effectively increase the overall load-bearing capacity. When not in use, the scissor rack mechanism 1 can close and drive the linkage mechanism 2 to close, reducing space occupation.

[0052] Example 2

[0053] Figure 3 The drying apparatus is schematically shown according to one embodiment of the above-described Example 1.

[0054] The drying device includes a pair of support frames 100 and a horizontal drying rod 200 disposed on the top of the support frames 100. The support frames 100 are linkage support frames as described above. The top ends of the main rods 11 corresponding to the pair of support frames 100 are respectively connected by a horizontal drying rod 200.

[0055] The drying device uses the aforementioned linkage support frame 100, which is easy to use and has a strong load-bearing capacity.

[0056] Example 3

[0057] Figure 4 The diagram schematically shows a linkage support frame 100 according to another embodiment of the present invention.

[0058] like Figure 4 As shown, the structure of the linkage support frame in this embodiment is basically the same as that of the linkage support frame in Example 1, except that: (1) the structures of the second rod 112 and the fourth rod 114 are different; (2) the structure of the second limiting mechanism 4 is different; and (3) the second hinge seat 24 is not provided.

[0059] like Figure 4 As shown, the second rod 112 and the fourth rod 114 of the linkage support frame in this embodiment are provided with limiting grooves 115 that cooperate with the linkage rod 21. The limiting grooves 115 are formed by two opposing extension pieces provided on the outer surfaces of the second rod 112 and the fourth rod 114. The second rod 112 and the fourth rod 114 are also provided with sliding grooves 116 that extend along the length direction of the second rod 112 and the fourth rod 114 and are connected to the limiting grooves 115. The sliding grooves 116 are provided on a pair of extension pieces. The second end (i.e. the bottom end) of the linkage rod 21 is slidably engaged with the sliding grooves 116 through a third hinge 25.

[0060] The linkage support frame also includes a first limiting mechanism 3 and a second limiting mechanism 4. The first limiting mechanism 3 is used to limit the first hinge seat 22, and the second limiting mechanism 4 is used to limit the third hinge member 25.

[0061] The first limiting mechanism 3 includes a first limiting member 31 disposed on the first rod 111 and the third rod 113 and cooperating with the first hinge seat 22;

[0062] The second limiting mechanism 4 is a slide 116.

[0063] It should be noted that the first hinge seat 22 in this embodiment can be slidably fitted onto the outer periphery of the main rod 1 or fixedly fitted onto the outer periphery of the main rod 1. That is, it is only necessary to ensure that the distance between the second hinge member 23 and the third hinge member 25 is adjustable.

[0064] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
