[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. In this utility model, the first limiting wall and the second limiting wall can limit the maximum rotation angle of the support legs during the unfolding and folding process, which is beneficial to the vibration unfolding and folding of the two sets of support legs. The second limiting wall can prevent the two sets of support legs from contacting and colliding with each other, and prevent the protective layer on the surface of the support legs from being damaged and corroded.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0040] See Figures 1 to 13 As shown, a drying rack includes a support frame 2 and a base frame 1. The support frame 2 is movably mounted on the base frame 1 and can be flipped and folded towards the base frame 1. The base frame 1 includes a connecting seat 12, on which two sets of support legs 11 are rotatably mounted. The two sets of support legs 11 can be unfolded relative to each other and jointly support the connecting seat 12. The two sets of support legs 11 can also be folded together relative to each other. The connecting seat 12 is provided with a first limiting wall 131 and a second limiting wall 132. The support legs 11 are provided with abutting walls 114 corresponding to the first limiting wall 131 and the second limiting wall 132. The abutting walls 114 can abut against the first limiting wall 131 and the second limiting wall 132 respectively, thereby limiting the maximum rotation angle of the support legs 11 during unfolding and folding. The support legs 11 abutting against the second limiting wall 132 can prevent the two sets of support legs 11 from contacting and colliding with each other. The structure limits the maximum rotation angle of the support legs 11 during unfolding and folding by the first limiting wall 131 and the second limiting wall 132, which is beneficial for the vibration unfolding and folding of the two sets of support legs 11. The second limiting wall 132 can prevent the two sets of support legs 11 from contacting and colliding with each other, and prevent the protective layer on the surface of the support legs 11 from being damaged and corroded. In addition, the structure can prevent the user's body from being pinched when the drying rack is folded, which helps to improve the safety of the drying rack and prevents the drying rack from damaging the clothes.

[0041] In this utility model, the first limiting wall 131 and the second limiting wall 132 can be arranged on the side of the support leg 11. In this embodiment, the support leg 11 is preferably rotatably arranged on the connecting seat 12 through the first hinge shaft 111. The support leg 11 includes a support part 112 arranged on the lower side of the first hinge shaft 111 and an extension part 113 arranged on the upper side of the first hinge shaft 111. The abutment wall 114 is arranged on the upper end of the extension part 113. This structure can prevent the support leg 11 from bending and deforming after the drying rack has been used for a long time, and prevent the bending of the support leg 11 from affecting the stability of the base frame 1, which is conducive to extending the service life of the drying rack.

[0042] The connecting seat 12 has a first hinge groove 13 on its lower side. One end of the support leg 11 passes through the first hinge groove 13. The first limiting wall 131 and the second limiting wall 132 are the side walls of the upper end of the first hinge groove 13. The first limiting wall 131 and the second limiting wall 132, located in the first hinge groove 13, are not easily touched by other objects. Furthermore, since the first hinge groove 13 is located on the lower side of the connecting seat 12, and the first limiting wall 131 and the second limiting wall 132 are located at the upper end of the first hinge groove 13, clothing or the user's body is unlikely to enter between the support leg 11 and the first limiting wall 131 or between the support leg 11 and the second limiting wall 132 during use. This can prevent injury to the user and avoid accidental damage.

[0043] The connecting seat 12 of this utility model is provided with a fixing cavity 15, which is located on the upper side of the first hinge groove 13. The first limiting wall 131 and the second limiting wall 132 are the side walls of the fixing cavity 15. An end cap 3 is detachably installed in the fixing cavity 15, and a supporting flange 31 is provided on the side of the end cap 3. The supporting flange 31 can abut against the side wall of the fixing cavity 15 and support the first limiting wall 131 and the second limiting wall 132. The fixed cavity 15 facilitates the injection molding production of the connecting seat 12, while the end cap 3 can support the abutment wall 114 and improve the structural strength of the connecting seat 12.

[0044] Preferably, the supporting flange 31 is generally annular, and has a portion parallel to the first limiting wall 131 and the second limiting wall 132. This portion is located on one side of the first limiting wall 131 and the second limiting wall 132 and supports the first limiting wall 131 and the second limiting wall 132. The annular supporting flange 31 has high structural strength, which can reduce deformation and damage of the supporting flange 31 during use. The end cap 3 can be fixed to the connecting seat 12 by fasteners. In this embodiment, the end cap 3 can be fixed in the fixing cavity 15 by the tight fit between the supporting flange 31 and the fixing cavity 15.

[0045] In this embodiment, a first hinge hole 133 for mounting the first hinge shaft 111 is located on the side wall of the first hinge groove 13. The fixing cavity 15 extends to the side of the first hinge groove 13 and communicates with the first hinge hole 133. The end cap 3 cooperates with the fixing cavity 15 to hide one end of the first hinge hole 133 communicating with the fixing cavity 15. This structure allows the first hinge hole 133 to be hidden, preventing other objects from affecting the relative rotation of the support leg 11 and facilitating the unfolding and folding of the support leg 11.

[0046] The connecting seat 12 of this utility model is provided with two sets of first limiting walls 131 and one set of second limiting walls 132. The two sets of first limiting walls 131 are arranged in a V-shape. The two sets of support legs 11 can respectively abut against the two sets of first limiting walls 131, so that the two sets of support legs 11 are spread out in a V-shape. The two sets of support legs 11 can simultaneously abut against the second limiting wall 132, so that the two sets of support legs 11 are arranged in parallel. This structure is simple and facilitates the production and processing of the connecting seat 12.

[0047] The connecting seat 12 is provided with two sets of support frames 2, which extend to both sides of the connecting seat 12 and can be flipped and folded towards the support legs 11. The connecting seat 12 is provided with a second hinge groove 14, and the support frame 2 is provided with a support rod and a connector 21. The connector 21 is rotatably disposed in the second hinge groove 14, and the connecting seat 12 is provided with a third limiting wall 141. The third limiting wall 141 can limit the relative rotation angle between the connector 21 and the connecting seat 12, thereby preventing the support rods from colliding with each other or the support rods from colliding with the support legs 11. The setting of the third limiting wall 141 can prevent the support rods from colliding with each other or the support rods from colliding with the support legs 11, and prevent the user's body and clothing from being pinched during the folding of the support frame 2, which is conducive to improving the safety of the drying rack and preventing the drying rack from damaging the clothes.

[0048] The connector 21 includes a connecting rod 212 and a hinge portion 211 rotatably disposed in the second hinge slot 14. The support rod is fixedly connected to the connecting rod 212, and the hinge portion 211 extends to the side of the connecting rod 212. It controls the relative folding of the two sets of support legs 11 and the folding of the support frame 2 towards the support legs 11. The connector 21 can increase the distance between the support rods on the two sets of support frames 2, thereby preventing the support rods from colliding with each other or with the support legs 11. This structure helps to increase the distance between the support rods on the two sets of support frames 2, preventing the user's body and clothing from being caught during the folding process of the support frame 2.

[0049] In this invention, the second hinge groove 14 is located on one side of the extension direction of the rotation center of the support leg 11, and the support rod can be folded to the side of the extension direction of the rotation center of the support leg 11. This structure can prevent the support frame 2 from bumping into the support leg 11 during folding, and prevent the support frame 2 from pinching the user's body and clothing during folding.

[0050] Preferably, the rotation centers of the two sets of support frames 2 are respectively located above and on both sides of the rotation centers of the two sets of support legs 11. This structure facilitates the support rods protruding from the sides of the support legs 11 after the support frame 2 is folded, making it easier for the user to control the unfolding of the support frame 2. Furthermore, this structure can distribute the vertical force on the connecting seat 12, preventing damage to the connecting seat 12 due to stress concentration. In this embodiment, the support frame 2 is rotatably mounted on the connecting seat 12 via a second hinge shaft. The connecting seat 12 is provided with a second hinge hole 142 for mounting the second hinge shaft. The positional relationship between the first hinge hole 133 and the second hinge hole 142 is shown in the attached drawing of the specification. Figure 10 As shown.

[0051] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
