[0026] To better understand the purpose, structure, and function of this invention, the journal display rack of this invention will be described in further detail below with reference to the accompanying drawings.

[0027] Figure 1 This is a schematic diagram of the structure of a magazine display rack according to an embodiment of the present invention, including several L-shaped trays 3 and baffles 1. Figures 2 to 8 As shown, the interior of tray 3 (the tray can be a hollow rectangular box) is equipped with a folding rod and a width-adjustable device. The width-adjustable device includes a telescopic plate 4, a sliding device 5 that cooperates with the telescopic plate 4, and a tension spring 18 that drives the sliding device 5. One end of the tension spring 18 is fixedly set with the sliding device 5, and the other end is fixed to the bottom of the baffle 1. The width of tray 3 is adjusted by pushing and pulling tray 3 to accommodate periodicals of different thicknesses, and the folding rod is unfolded to prevent periodicals from folding at the corners. When placing or returning periodicals, pulling tray 3 outwards drives the sliding device 5, which in turn drives the telescopic plate to widen the thickness of tray 3. The tension spring 18 presses multiple periodicals or thicker periodicals between the side wall 2 of the tray and the baffle 1. The folding rod unfolds in different directions according to the spine position of the periodicals, which can prevent periodicals from being placed for a long time or borrowed multiple times, resulting in paper corners, curling, or wrinkles. When taking out or borrowing a periodical, the folding rod is extended to the inside of the side plate 2 of the tray, and the tray 3 is pulled outward to drive the sliding device 5. The sliding device 5 drives the telescopic plate to widen the thickness of the tray 3. Then, the telescopic plate 4 is returned to its original position by the tension spring 18. The periodical display rack of this embodiment can adapt to periodicals of different thicknesses and prevent periodicals from folding at the corners.

[0028] In some embodiments, such as Figure 2 , Figure 3 As shown, the telescopic plate 4 includes multiple telescopic support plates (first telescopic plate 7, second telescopic plate 8, and third telescopic plate 9). Each telescopic support plate has a pair of ball linear guides at its lower part to support and guide each telescopic support plate to perform reciprocating linear motion. The ball linear guides are formed by steel balls rolling infinitely between the slider and the guide rail, which enables the telescopic support plate to easily perform high-precision linear motion along the guide rail and reduces the coefficient of friction to about 1 / 50 of that of traditional sliding guides.

[0029] In some embodiments, as shown in Figure 4 The sliding device includes a square channel 12, three groups of bearings 13, and a bracket (bearing upper bracket 10) and a side plate (bearing side bracket 11) that fix the bearings 13, the square channel 12 is arranged at an angle of 45 degrees, one group of bearings 13 is tightly arranged on the upper two sides of the square channel 12, and the other two groups of bearings 13 are tightly arranged in parallel on the lower two sides of the square channel 12. Each bearing 13 forms a line contact (bearing and square channel contact line 14) with the side of the square channel 12. The bearing line contact has large carrying capacity, high stiffness, and small friction generated between the bearing and the square channel 12. The three groups of bearings 13 make the sliding device more stable.

[0030] In some embodiments, as shown in Figure 5 , Figure 6 The upper two sides of the square channel 12 are provided with a pair of strip-shaped through grooves 15. One end of the tension spring 18 is provided with a pair of fixed rods (first fixed rod 16 and second fixed rod 17), and the fixed rods pass through the strip-shaped through grooves 15 and are fixedly arranged with the sliding device. Thus, the tension of the tension spring 18 is transmitted to the telescopic plate 4 through the sliding device by means of the strip-shaped through grooves 15.

[0031] In some embodiments, as shown in Figure 1 , Figure 7 The supporting plate 3 is provided with a transmission device, and power is transmitted to the folding rod through the transmission device. When the supporting plate 3 is pushed and pulled, the folding rod is controlled to be unfolded and telescopic. The transmission device can be a linkage structure.

[0032] In some embodiments, as shown in Figure 1 The side of the supporting plate 3 is provided with a plurality of uniformly distributed clamping grooves, and the side of the baffle 1 is matched through the clamping grooves. The clamping groove matching mode facilitates the quick installation of the L-shaped supporting plate 3 and the baffle 1.

[0033] In some embodiments, as shown in Figure 3 The two side edges of the telescopic plate (7, 8, 9) are pressed and combined with gaskets on the upper part to prevent damage to the periodical.

[0034] In some embodiments, as shown in Figure 8 The tension spring 18 is composed of a pair of series springs (first spring 20 and second spring 21). The first spring 20 and the second spring 21 are connected end to end, and the elongation of the two is the same. When the two springs are connected in series, one of them plays a balancing role, and the other plays an adjusting role. The inside of each spring is provided with a plurality of circular stack-shaped support side walls 19 matched with the threads of each spring. The support side wall 19 is beneficial to prevent the spring from deforming due to stress.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, each technical feature mentioned in each embodiment can be combined in any way.
