The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The technical solution of the present invention will be described in detail with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Referring to fig. 1 to 15, a shelf 1 provided in the present embodiment is specifically illustrated; the first embodiment is shown in fig. 1 to 10, the second embodiment is shown in fig. 11 to 15, the article placing rack 1 includes at least one set of limiting parts, the limiting parts include a first limiting unit 111 and a second limiting unit 121, the first limiting unit 111 and the second limiting unit 121 are correspondingly arranged at intervals in the vertical direction, the article 4 placed on the article placing rack 1 is limited by the first limiting unit 111 and the second limiting unit 121 at the same time, and the article placing rack 1 is formed by integrally cutting and bending a first plate. It should be mentioned that the article placing rack 1 includes a flat state and an assembled state, the flat state refers to a state that the first plate forming the article placing rack 1 is unfolded, the assembled state refers to a state that the first plate forming the article placing rack 1 is bent to place the article 4 to be packaged, wherein the flat state of the article placing rack of the first embodiment is shown in fig. 2, the assembled state of the article placing rack of the first embodiment is shown in fig. 5, the flat state of the article placing rack of the second embodiment is shown in fig. 11, and the assembled state of the article placing rack of the second embodiment is shown in fig. 13. It will be understood that the article carrier 1 also comprises a semi-assembled condition between the flat condition and the assembled condition, i.e. the condition before the first sheet constituting the article carrier 1 has undergone several bends but has not been completely formed into the assembled condition, as shown in figures 3, 4 and 12. In the embodiment of the present invention, if there is no other description, the structural position relationship is described when the rack is in the assembled state. In a specific embodiment, the first limiting unit 111 and the second limiting unit 121 are through holes penetrating through the first plate respectively, the first limiting unit 111 is located right above the second limiting unit 121 after the first plate is bent for several times, and a certain interval is provided between the first limiting unit 111 and the second limiting unit 121, the to-be-packaged article 4 sequentially passes through the first limiting unit 111 and the second limiting unit 121 from top to bottom, and is simultaneously clamped in the through hole structures of the first limiting unit 111 and the second limiting unit 121, so as to fix the to-be-packaged article 4. Preferably, the first plate can be corrugated paper, and is formed with a plurality of crease lines, and bends the first plate for a certain angle along the crease lines, so as to obtain the article rack 1 capable of placing the article to be packaged 4, and the first plate is roughly kept in the bent state after bending operation with no less than preset force. Because the manufacturers of the packaging box and the commodity shelf 1 arranged in the packaging box are usually different from the sellers of the objects 4 to be packaged, the commodity shelf 1 is formed by integrally cutting and bending a first plate, so that the commodity shelf is convenient to transport from the manufacturers to the sellers in a flat state and is bent into an assembled state for use in the sellers; in addition, can be through setting up the height of multiunit crease in order to adjust supporter 1 at first panel simultaneously, for example, 1 height of supporter that the first panel of buckling along first group crease line obtained is A, 1 height of supporter that the first panel of buckling along second group crease line obtained is B, and A is different with B to make the production line need not the die sinking again and can satisfy the demand of fixed different height waiting to pack article 4. It should be noted that the integral cutting means that the single independent storage rack 1 is obtained by cutting the corresponding single first plate, for example, by forming the limiting portion by breaking the hole and cutting off the redundant portion, rather than the single independent storage rack 1 is obtained by splicing the plurality of first plates, for example, by pasting, it can be understood that the plurality of storage racks 1 can be obtained by cutting the plurality of first plates at the same time, and the operation still belongs to the integral cutting range.

The commodity shelf 1 provided by the utility model fixes the object 4 to be packaged by adopting the first limiting unit 111 and the second limiting unit 121 which are arranged at intervals, the fixing mode is firm, and the object 4 to be packaged is effectively prevented from shaking relative to the commodity shelf 1 in the transportation process to cause damage; meanwhile, the storage rack 1 is integrally cut from the first plate and bent to form a flat laying state and an assembling state, the flat laying state which occupies a small volume is adopted during transportation, and the assembling state is adopted during use, so that the storage rack can be flexibly switched according to needs to meet the requirements of users; moreover, the shelf 1 is assembled by bending, and a plurality of groups of crease lines can be arranged at the same time to adjust the height of the shelf 1.

Preferably, the first limiting unit 111 and the second limiting unit 121 have the same shape, so that the fixing device is suitable for fixing a structure with a relatively regular outer contour of the article 4 to be packaged, for example, a part of the contour of the article 4 to be packaged is a cuboid, the first limiting unit 111 and the second limiting unit 121 can be both rectangular, or the cross section of a part of the contour of the article 4 to be packaged is trapezoidal, and the first limiting unit 111 and the second limiting unit 121 can be both trapezoidal. Further preferably, the storage rack 1 comprises a plurality of sets of limiting parts, wherein at least two sets of limiting parts have different shapes to place different articles 4, in a specific embodiment, when the articles 4 to be packaged are kits or assemblies, a plurality of kits or a plurality of assemblies can be fixed on the same storage rack 1 to be placed in the same packaging box, for example, the articles 4 to be packaged comprise a first assembly and a second assembly which have different shapes, the storage rack 1 correspondingly comprises a first set of limiting parts and a second set of limiting parts, the first set of limiting parts are matched with the first assembly in shape, the second set of limiting parts are matched with the second assembly in shape, namely, the first set of limiting parts and the second set of limiting parts have different shapes. The at least two groups of limiting parts have different shapes, including that the first limiting unit 111 and the second limiting unit 121 in the limiting parts for comparison have different shapes, or the first limiting unit 111 in the limiting parts for comparison have different shapes, or the second limiting unit 121 in the limiting parts for comparison have different shapes.
