[0069] The preferred embodiments of the present application are described below with reference to the accompanying drawings, so that the technical contents of the present application are more clear and convenient to understand. The present application can be embodied in many different forms, and the protection scope of the present application is not limited to the embodiments described herein.

[0070] In the drawings, components of the same structure are denoted by the same reference numerals, and components similar in structure or function are denoted by similar reference numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the size and thickness of each component are not limited in the present application. In order to make the drawing clearer, the thickness of some components is appropriately exaggerated in some places in the drawing.

[0071] As shown in FIG. 1 and FIG. 2, the present application provides a shelf 10, which includes vertical beams 100, first beams 200 and shelves 500. The vertical beams 100 are four vertical beams arranged in four directions, and the two ends of the first beams 200 are connected to the vertical beams 100, respectively. The four first beams 200 form a layer, and the first beams 200 are provided with support surfaces 201, and the shelves 500 are placed on the support surfaces 201. One shelf 10 can be provided as multiple layers according to needs, and the distance between the layers is variable. The shelves 500 can be selected from a variety of forms such as mesh plates, flat plates, wooden plates, etc., and the form of the shelves 500 does not constitute a limitation on the present application.

[0072] Referring to FIG. 2 and FIG. 29, the ends of the first beams 200 are connected to the vertical beams 100, and the connection structure of the two can adopt any structure known in the prior art, and the connection structure of the first beams 200 and the vertical beams 100 does not constitute a limitation on the present application. Preferably, a plurality of holes 103 (see FIG. 25) are arranged on the vertical beams 100 in the length direction in sequence, and the ends of the first beams 200 are connected to the holes 103, for example, the ends of the first beams 200 can be connected to the holes by any known means such as buckles, fasteners 104, etc. By arranging the first beams 200 at different positions of the holes 103, different heights of the layer can be achieved. When the shelf 10 is provided as multiple layers, the variable distance between the layers can also be achieved. The shape of the holes 103 can be set according to actual needs, including but not limited to square holes, round holes, water drop holes shown in FIG. 29 (i.e. the upper part of the hole 103 is a round hole, and a communicating groove is arranged below the round hole, and the width of the groove is smaller than the diameter of the round hole). In the present application, FIG. 30 shows a way of connecting the first beams 200 and the vertical beams 100, in which the ends of the first beams 200 have rivets, which can be clamped into the holes 103 to achieve clamping.

[0073] Referring to FIG. 3, the first beam 200 is long strip-shaped, and includes a first beam body 203, a support surface 201, and at least one reinforcing portion. The support surface 201 is used to support the shelf 500, and can be formed by bending the first beam 200. The reinforcing portion is used to improve the support strength of the first beam 200. In some embodiments, as shown in FIGS. 3 and 4, the support surface 201 is formed by bending the upper edge of the first beam 200 twice along the height direction, and meanwhile, the first beam body 203 is bent along the length direction to form a first protruding portion 210 as a reinforcing portion of the first beam 200. The first protruding portion 210 includes a first surface 211 and a second surface 212, and the second surface 212 intersects with the first surface 211 at an acute angle. In some embodiments, as shown in FIGS. 5 and 6, the first surface 211 of the first protruding portion 210 is used as the support surface 201, and the second surface 212 is used as the reinforcing portion.

[0074] In some embodiments, a reinforcing portion of the first beam 200 is formed at the lower edge of the first beam 200 away from the support surface. As shown in FIGS. 3-6, the lower edge of the first beam 200 can be bent or rolled to form a second protruding portion 220 as another reinforcing portion of the first beam 200. The second protruding portion 220 can be arc-shaped. Preferably, the lower edge of the first beam 200 is continuously bent and plastically deformed by rolling to obtain the shape required by the second protruding portion 220.

[0075] Referring to FIGS. 2, 7 and 8, to further improve the bearing capacity of the first beam 200, the storage rack 10 further includes a second beam 300 arranged between two opposite first beams 200. The second beam 300 is long strip-shaped, and the two ends of the second beam 300 are provided with first positioning portions 301, and the first beam 200 is provided with second positioning portions 302, the first positioning portions 301 are detachably connected to the second positioning portions 302, so as to realize quick positioning and connection of the first beam 200 and the second beam 300. To avoid interference between the reinforcing portion of the first beam 200 and the end of the second beam 300, the end of the second beam 300 is further provided with a avoiding slot 303 for accommodating the reinforcing portion. For example, as shown in FIG. 11, the end of the second beam 300 is provided with the avoiding slot 303, which can accommodate the first reinforcing portion of the first beam 200, and when the second beam 300 is connected to the first beam 200, the first reinforcing portion is located in the avoiding slot 303.

[0076] In some embodiments, referring to FIG. 8, the first positioning part 301 is a groove 310 with an opening 311 (see FIG. 13), and the second positioning part 302 is a protrusion 312 that can pass through the opening 311 into the groove 310, for example, the protrusion 312 can be a rivet. The rivet can be a cylindrical solid rivet, and the opening in the first beam 200 is also a circular hole. The circular hole is the least likely to generate stress concentration and has the least damage to the load-bearing capacity of the beam. Moreover, the solid rivet can also support the first beam when bearing force. The rivet is driven into the first beam 200, and the head of the rivet forms the protrusion 312 on the first beam 200. The protrusion 312 and the groove 310 are detachably engaged, thereby achieving quick connection. The shape of the groove 310 can be any suitable shape. Preferably, referring to FIG. 13, the groove 310 is a circular arc groove, and the opening 311 is a narrow opening, i.e., the size of the opening 311 is smaller than the diameter of the circular arc groove. In some embodiments, referring to FIGS. 8-13, the end of the second beam 300 is provided with a clamping part 320 in the form of a thin sheet, and then the groove 310 with the opening 311 is arranged on the clamping part 320. Preferably, in order to reduce the damage to the load-bearing capacity of the first beam 200, the rivet is not generally arranged in the middle of the first beam 200, but is evenly distributed on at least one pair of the first beam 200, for example, as shown in FIGS. 33 and 34, a pair of protrusions 312 (formed by arranging a rivet on the first beam 200) are arranged on the first beam 200, and each protrusion 312 is not located in the middle of the first beam 200, but is biased towards the end of the first beam 200.

[0077] In some embodiments, a reinforcing part is arranged on at least one edge of the second beam 300 main body 304 in the height direction, and then a groove 310 with an opening 311 is arranged at the end of the reinforcing part.

[0078] For example, as shown in FIGS. 9 and 13, the upper edge of the second beam 300 main body is bent to form a third protruding part 330 with an upper surface 331, and the end of the third protruding part 330 is located on the support surface 201 of the first beam 200. Referring to FIG. 14, the groove 310 is arranged at the end of the third protruding part 330 as the first positioning part, and the protrusion 312 is arranged on the surface of the second protruding part 220 of the first beam 200 as the second positioning part 302.

[0079] For example, referring to FIGS. 9 and 13, the lower edge of the second beam 300 main body is bent to form a fourth protruding part 340, and the end of the fourth protruding part 340 is located on the second protruding part 220 of the first beam 200; the groove 310 is arranged at the end of the fourth protruding part 340 as the first positioning part, and the protrusion 312 is arranged on the surface of the second protruding part 220 of the first beam 200 as the second positioning part 302.

[0080] It should be understood that the third protrusion 330 and the fourth protrusion 340 shown in FIG. 9 and FIG. 13 can be provided simultaneously or separately. When the third protrusion 330 and the fourth protrusion 340 are provided simultaneously, the groove 310 as the first positioning part can be provided only on one of the third protrusion 330 and the fourth protrusion 340, or can be provided on both the third protrusion 330 and the fourth protrusion 340 (see FIG. 15).

[0081] In some embodiments, as shown in FIG. 16, the groove 310 can be provided at the end of the main body 304 of the second beam 300.

[0082] In some embodiments, referring to FIG. 17-20, the first positioning part 301 is a downward protruding lug 350 provided at the end of the second beam 300, and the second positioning part 302 is a hole 351 provided on the first beam 200 for the lug 350 to pass through, so that the first beam 200 and the second beam 300 are quickly positioned and connected by passing the lug 350 through the hole 351. For example, as shown in FIG. 18 and FIG. 19, the upper edge of the second beam 300 is bent to form a third protrusion 330, the end of the third protrusion 330 extends along the length direction of the second beam 300 and then is bent downward to form a lug 350, and the corresponding position of the support surface 201 of the first beam 200 is provided with a hole 351. It should be understood that the lower edge of the second beam 300 can also be bent to form a lug 350 in a similar manner, i.e., the lower edge of the second beam 300 is bent to form a fourth protrusion 340, the end of the fourth protrusion 340 extends along the length direction of the second beam 300 and then is bent downward to form a lug 350, and a hole is formed at the lower edge of the first beam 200 for the lug 350 of the fourth protrusion 340 to pass through. In some embodiments, as shown in FIG. 20, the lug 350 can be formed by bending the end of the main body 304 of the second beam 300 along the length direction.

[0083] The second beam 300 has the third protrusion 330 and the fourth protrusion 340 shown in FIG. 9-20, which have the effect of strengthening the load bearing capacity of the second beam 300. In some embodiments, more strengthening parts can also be provided on the second beam 300. For example, as shown in FIG. 21 and FIG. 22, a fifth protrusion 360 is provided on the edge of the fourth protrusion 340 in the direction of the third protrusion 330, which can serve as a strengthening part of the second beam 300. For example, as shown in FIG. 23 and FIG. 24, a sixth protrusion 370 protruding outward can be formed by bending the middle part of the second beam 300, which can serve as a strengthening part of the second beam 300; the sixth protrusion 370 includes a first face 371 and a second face 372 extending along the length direction of the second beam 300, and the first face 371 and the second face 372 intersect.

[0084] In addition, the second beam 300 can be provided with a hanging hole 305 for hanging some articles or for hoisting the second beam 300. By providing the hole 305, the second beam 300 can be conveniently hung during processing, for example, to facilitate hanging the second beam 300 during plastic spraying.

[0085] Referring to FIGS. 2 and 25, in order to extend the height of the shelf 10, the shelf 10 can further include a connecting piece 400 that can connect two vertical beams 100 together along the length direction of the vertical beams 100 to form a longer vertical beam 100. The connecting piece 400 can limit the relative movement of the two vertical beams 100 in the non-length direction, so that the two vertical beams 100 can be stably connected to form a whole. As shown in FIG. 25, the vertical beam 100 includes a first side edge 101 and a second side edge 102 that are substantially perpendicular. As shown in FIGS. 26-28, the connecting piece 400 has substantially the same cross-sectional shape as the vertical beam 100, and specifically, the connecting piece 400 includes a first body 410 and a second body 420 that are substantially perpendicular, a first edge 411 of the first body 410 intersects a first edge 421 of the second body 420, a second edge 412 of the first body 410 opposite to the first edge 411 forms a first clamping portion 413, a second edge 422 of the second body 420 opposite to the first edge 421 forms a second clamping portion 423, the first clamping portion 413 and the second clamping portion 423 have a U-shaped cross-sectional shape, and a space in the U-shaped cross-sectional shape forms a channel 401 for the vertical beam 100 to enter. When the end of the vertical beam 100 enters the U-shaped space, the first clamping portion 413 wraps around the outer edge of the first side edge 101 of the vertical beam 100, and the second clamping portion 423 wraps around the outer edge of the second side edge 102 of the vertical beam 100. Through the limitation of the first clamping portion 413 and the second clamping portion 423, after the two vertical beams 100 are connected together along the length direction, the relative movement in the non-length direction is limited, except that the freedom in the length direction is not limited. FIG. 33 shows the shelf 10 without the connecting piece 400, and FIG. 2 shows the shelf 10 with the connecting piece 400. By providing the connecting piece 400, the height of the shelf 10 can be increased, and the space utilization can be improved. The connecting piece 400 can be provided according to actual needs.

[0086] In some embodiments, referring to FIG. 28, a first protrusion 430 is provided in each of the first clamping portion 413 and the second clamping portion 423 and faces the inner wall of the clamping portion. The protrusion 430 can be formed by stamping. Through the first protrusion 430, a barrier is formed for the vertical beam 100, that is, when the end of the vertical beam 100 enters the U-shaped space of the clamping portion, the vertical beam 100 cannot continue to move in the U-shaped space of the clamping portion when the end of the vertical beam 100 contacts the first protrusion 430. The first protrusion 430 forms a barrier for the vertical beam 100, which facilitates positioning during installation by the consumer.

[0087] In some embodiments, referring to FIG. 27, the two ends of the connecting member 400 along the length of the vertical beam 100 can also be provided with a second protrusion 440, which is formed by the portion where the first body 410 and the second body 420 intersect, and extends along the length. The second protrusion 440 is formed to wrap around the intersection of the two side edges of the vertical beam 100. When the vertical beam 100 is provided with multiple holes 103 connected to the first beam 200, the second protrusion 440 can increase the contact surface between the vertical beam 100 and the connecting member 400, and will not block the holes 103 of the vertical beam 100.

[0088] In some embodiments, referring to FIGS. 31 and 32, the connecting member 400 is provided with multiple avoiding holes 402, which are located corresponding to the positions of the holes 103 on the vertical beam 100, so that the first body 410 and the second body 420 of the connecting member 400 will not block the holes 103 on the vertical beam 100, thereby avoiding interfering with the connection between the vertical beam 100 and the first beam 200. The shape of the avoiding hole 402 can be substantially matched with the shape of the hole 103, for example, as shown in FIG. 31, the hole 103 of the vertical beam 100 is a water drop hole, and the shape of the avoiding hole 402 is also a water drop hole. It should be understood that the avoiding hole 402 can also be provided with other shapes different from the hole, as long as the size of the avoiding hole 402 is larger than the size of the hole, so that the first body 410 and the second body 420 do not block the hole, for example, as shown in FIG. 32, the avoiding hole 402 adopts a runway round hole.

[0089] In some embodiments, the first body 410 and the second body 420 of the connecting member 400 are provided with a hanging hole 403.

[0090] The connecting member 400 is used to connect two vertical beams 100 in sequence, therefore, the connecting member 400 needs to have a certain length to ensure that the connecting member 400 has sufficient contact surface with the two vertical beams 100, and to ensure the limitation on the vertical beam 100. In some embodiments, as shown in FIG. 29, when the vertical beam 100 is uniformly provided with multiple holes 103 along the length, wherein the distance between the hole 103a of the upper vertical beam (the hole 103a is spaced apart from the lower vertical beam by one hole) and the hole 103b of the lower vertical beam (the hole 103b is spaced apart from the upper vertical beam by one hole) is H, and the length of the body of the connecting member 400 is h, which can not include the length of the second protrusion 440 extending outward, h is less than H. Preferably, H is 92.5 mm. It should be understood that the length of the connecting member 400 can be set according to the actual situation, and is not limited to the size shown in FIG. 29.
