Description

A foldable shoe rack device

technical field

The invention relates to a foldable shoe rack device, which belongs to the technical field of daily necessities.

Background technique

In recent years, there are many shoes in the life of college students, and the shoe racks provided in most university dormitories cannot put so many shoes. If you buy shoe racks on the market, firstly, because the dormitory area of college students is generally relatively small, placing shoe racks will hinder the living space of students; secondly, the school does not allow the addition of large wardrobes and shoe racks from outside, which will affect the tidiness of the dormitory The hygiene score will be deducted when the housekeeper aunt checks the hygiene. The shoe rack arranged under the bed is easy to attract dust because there is no external cover, making the shoes dirty.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a shoe rack that can be folded and placed under the bed, which not only reduces the floor space in the room, but also does not destroy the neatness of the room, and at the same time achieves the purpose of placing shoes , The purpose of preventing the shoes from getting dirty.

In order to solve the above-mentioned technical problems, the present invention provides a foldable shoe rack device, which includes a box for placing shoes, and is characterized in that it includes at least two layers of boxes, and a There is a set of link mechanism, the link mechanism includes a first link and a second link, wherein one end of the first link and the second link are respectively connected between two adjacent boxes through the first rotating shaft and the third rotating shaft. On the back of the body, the other ends of the first connecting rod and the second connecting rod are connected together through the second rotating shaft.

Further, the box is in the shape of a cuboid shoebox with one side open and three sides closed.

Further, the opening is also provided with a flip cover, which can keep out dust.

Further, both ends of the first connecting rod and the second connecting rod are provided with through holes, and the first rotating shaft, the second rotating shaft and the third rotating shaft all use bolts, and the bolts pass through the first connecting rod and the second connecting rod. The through hole of the second connecting rod connects the first connecting rod, the second connecting rod and the box body to each other.

Further, screw holes matching the bolts are provided on the back of the box.

Further, the outer diameter of the screw rod of the bolt is smaller than the diameter of the through hole, and the outer diameter of the head of the bolt is larger than the diameter of the through hole.

Further, the connecting rod mechanisms of two adjacent groups are connected end to end.

The beneficial effect that the present invention reaches:

Compared with the prior art, the present invention provides a foldable shoe rack device, which can effectively fold the vertically tall shoe rack and place it under the bed by using the coordinated work of the various parts, which not only reduces the size of the room It takes up a small space without destroying the order of the room, and at the same time achieves the purpose of placing shoes. The invention is suitable for use in college students' dormitories.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

As shown in Figures 1-3, a foldable shoe rack device includes a box for placing shoes, which is characterized in that it includes four layers of boxes (the boxes from the first layer to the fourth layer are marked as 1~4), there is a set of link mechanisms between the backs of every two adjacent boxes (in this embodiment, the link mechanism between the third box and the fourth box is taken as an example), so The link mechanism includes a first connecting rod 8 and a second connecting rod 6, wherein one end of the first connecting rod 8 and the second connecting rod 6 are respectively connected to two adjacent boxes through the first rotating shaft 9 and the third rotating shaft 5 On the back, the other ends of the first connecting rod 8 and the second connecting rod 6 are connected together through the second rotating shaft 7 .

In this embodiment, the box is in the shape of a cuboid shoe box with one side open and three sides closed. According to the length, width and height of a general shoe box, its length, width and height are designed to be 350×250×120 mm, and the inside is hollow to place shoes.

In the present embodiment, since the width of each layer of shoebox is 250mm and the height is 120mm, the diameter of the connecting rod and the box hole is 5mm, and the diameter of the connecting hole between the two rods is 5mm. The center of the box hole is set at the lower left part of the back of the box, the distances from the left and right sides are 75mm and 165mm respectively, and the distances from the upper and lower sides are 80mm and 40mm respectively. When the upper box moves to the right and folds, the calculated limit position is when the lower left vertex of the upper box coincides with the upper right vertex of the lower box. At this time, a right triangle is formed, and the two right angles The side lengths are 250mm and 120mm respectively. According to the Pythagorean theorem, it can be calculated that the length of the hypotenuse formed by the two connecting rods is 277.41mm, so we design the sum of the lengths of the two connecting rods to be 285mm. Therefore, the second connecting rod 6 is designed to be 160 mm, and the first connecting rod 8 is 125 mm. According to calculations, such a length selection can prevent interference between the upper and lower boxes when the connecting rods are folded and unfolded. At the same time, the horizontal connection between these two rods and the box hole forms a triangle again, and the three sides are respectively 160mm, 125mm and 250mm. According to the law of cosines, the height of this triangle is 67.75mm, which is less than 80mm. This can ensure that the connecting bolts between the connecting rods will not be higher than the box body, reduce the folding space, and realize the function of rotation.

In this embodiment, the opening is also provided with a flip cover, which can block dust.

In this embodiment, both ends of the first connecting rod and the second connecting rod are provided with through holes, the first rotating shaft, the second rotating shaft and the third rotating shaft all use bolts, and the bolts pass through the first connecting rod and the through hole of the second connecting rod to connect the first connecting rod, the second connecting rod and the box; the back of the box is provided with a screw hole matching the bolt; the outer diameter of the screw of the bolt is less than The diameter of the through hole, the outer diameter of the head of the bolt is larger than the diameter of the through hole, which can ensure the rotation of the first connecting rod and the second connecting rod, and limit the positions of the ends of the first connecting rod and the second connecting rod .

In this embodiment, two adjacent groups of link mechanisms are connected end to end. For example, the link mechanism in the middle has its first link connected to the second link mechanism of the link mechanism adjacent below it, and the second link mechanism of the link mechanism in the middle The rod is connected to the first link of the connecting mechanism adjacent above it.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
