[0026] SeeFigures 1 to 5 , the present utility model relates to a caster mounting seat 100 for a storage box (hereinafter referred to as "mounting seat 100") and a storage box using the mounting seat 100. Among them, the structure of the mounting seat 100 is simple, easy to install, and has high structural strength. The storage box realizes the detachable installation of the caster 300 through the mounting seat 100. The caster 300 can be installed to facilitate the movement of the storage box. After the movement is completed, the caster 300 can be removed, or the caster 300 can be replaced according to needs. It should be understood that the bottom of the storage box body 200 of the present utility model has a skirt 210, which is formed by extending outward and downward from the bottom surface of the storage box body. The skirt 210 is provided with an arc edge corresponding to the corner end of the storage box and straight edges connected to both ends of the arc part. The skirt 210 can be press-fitted to the bottom of the storage box body through a pressing process.

[0027] As Figure 1 and Figure 2 shown, the mounting seat 100 is adapted to be installed at the bottom corner end of the storage box body 200, and includes a seat plate 10, a pair of hooks 20 and a pair of fastening arms 30. The hooks 20 and the fastening arms 30 are both formed by bending downward from the side edge of the seat plate 10.

[0028] The seat plate 10 is made of a metal material such as stainless steel or aluminum, and is provided with a caster mounting hole penetrating through the upper and lower surfaces. The caster mounting hole is used to pass through a connecting piece such as a screw to install the caster 300.

[0029] The seat plate 10 includes a rounded corner portion 11, two first straight edge portions 112 that are connected to both ends of the rounded corner portion 11 and are perpendicular to each other, and a second straight edge portion 113 that is perpendicularly connected to the first straight edge portion 112 at the end of the first straight edge portion 112 away from the rounded corner portion 11.

[0030] The pair of hooks 20 are respectively connected to the two first straight edge portions 112, and are used to respectively buckle on the outer sides of the two straight edges at the bottom end of the storage box. The hook 20 includes a clamping arm 21 connected to the first straight edge portion 112 and an inwardly inclined and bent inner buckling portion 22 formed at the end of the clamping arm 21. The clamping arm 21 is in a straight plate shape and is used to fit on the outer side of the skirt 210 when the mounting seat 100 is installed on the storage box. The inner buckling portion 22 is used to buckle on the upper end of the skirt 210.

[0031] The fastening arm 30 is vertically connected to the second straight edge portion 113 and extends in a direction away from the second straight edge. There is a gap 15 between the fastening arm 30 and the inner side surface of the clamping arm 21. The width of the gap 15 is set to match the thickness of the skirt 210 of the storage box, so that when the mounting base 100 is mounted on the storage box, the skirt 210 of the storage box is clamped within the gap 15. A fastening screw hole is provided on the fastening arm 30 for passing a fastening screw to press against the inner side of the skirt 210, thereby completing the fixation of the mounting base 100 and the storage box.

[0032] In a preferred embodiment, the skirt 210 of the storage box is clamped within the gap 15, and its inner side surface abuts against the fastening arm 30, and the outer side surface abuts against the clamping arm 21 of the hook 20.

[0033] Thus, in the present utility model, the hook 20 and the fastening arm 30 are formed by bending the side of the seat plate 10, and a gap 15 matching the skirt 210 of the storage box is formed between the hook 20 and the fastening arm 30. When the seat plate 10 is placed on the bottom corner of the storage box, the skirt 210 is clamped within the gap 15 and abuts tightly against the fastening arm 30 and the clamping arm 21, and is fastened by a fastening screw, completing the assembly of the mounting base 100 and the storage box body. During the assembly process, only the seat plate 10 needs to be placed and the fastening screw tightened, which is convenient to operate, greatly saves the assembly time, and improves the user experience.

[0034] Wherein, the radian of the outer arc 111 of the rounded corner portion 11 is the same as the radian of the outer arc of the bottom corner of the storage box body, improving the buckling effect between the mounting base 100 and the bottom of the storage box and enabling the mounting base 100 to fit well on the bottom corner of the storage box when mounted on the storage box.

[0035] The mounting base 100 further includes a support arm 40. The upper end of the support arm 40 is connected to the second straight edge portion 113, and the other end extends downward to form the support arm 40. The height of the support arm 40 is set to match the distance between the top surface of the seat plate 10 and the bottom surface of the storage box body, so that the end of the support arm 40 away from the second straight edge portion 113 abuts against the bottom surface of the storage box, providing support for the seat plate 10 and preventing the position of the seat plate 10 away from the rounded corner portion 11 from sagging under force, thereby improving the reliability of the connection structure between the mounting base 100 and the storage box.

[0036] Preferably, the end of the support arm 40 away from the second straight edge portion 113 is bent inward to form a contact portion 41. The contact portion 41 is in a flat plate shape, so that the support arm 40 and the bottom surface of the storage box are in surface contact, expanding the contact area and preventing the contact portion 41 of the storage box from being damaged due to excessive pressure, further improving the stability of the support structure.

[0037] The fastening arm 30 is a straight arm 31, which is connected to one end of the support arm 40 close to the hook 20. Preferably, the fastening arm 30 is formed by bending outward from one end of the support arm 40 close to the hook 20.

[0038] Among the pair of support arms 40, the pair of fastening arms 30 and the pair of hooks 20, the two components of each are symmetric about the angular bisector of the rounded corner portion 11, that is, the two support arms 40 are symmetric about the angular bisector of the rounded corner portion 11, the two fastening arms 30 are symmetric about the angular bisector of the rounded corner portion 11, and the two hooks 20 are symmetric about the angular bisector of the rounded corner portion 11.

[0039] A nut member 32 is crimped on the fastening arm 30, so that an internal thread is formed on the fastening arm 30, and it is thread-fixed with the fastening screw. It can be understood that the longer the length of the fastening arm 30, the more the number of nut members 32, and the better the fastening effect of the mounting seat 100, but the longer the installation time required. Preferably, there are two nut members 32 to improve the fastening effect between the mounting seat 100 and the storage box on the basis of ensuring the assembly efficiency of the storage box.

[0040] In addition, the nut member 32 protrudes and extends toward the plane of the inner side of the hook 20, so as to abut against the inner side of the skirt 210 when the mounting seat 100 is assembled with the storage box body.

[0041] There are multiple pairs of caster mounting holes, and the multiple pairs of caster mounting holes are arranged at intervals along the direction away from the rounded corner portion 11. Among them, a pair of caster mounting holes close to the rounded corner portion 11 are used as mandatory mounting holes, and the remaining pairs of mounting holes are used as optional mounting holes for adapting to and mounting casters 300 of different models. The casters 300 of different models are all mounted on the seat plate 10 by using this pair of mandatory mounting holes in combination with one pair or multiple pairs of optional mounting holes.

[0042] In this embodiment, there are three pairs of caster mounting holes 12 on the seat plate 10, where a pair of caster mounting holes 12 are used as mandatory mounting holes 121, and the other two pairs of caster mounting holes 12 are used as optional mounting holes 122. Among them, a pair of optional mounting holes 122 close to the mandatory mounting holes 121 and the mandatory mounting holes 121 are jointly used for mounting the casters 300 with a smaller size, and a pair of optional mounting holes 122 far from the mandatory mounting holes 121 and the mandatory mounting holes 121 are jointly used for mounting the casters 300 with a larger size.

[0043] It can be understood that each pair of caster mounting holes 12 are respectively arranged on both sides of the angular bisector. It can be understood that the distances from the two caster mounting holes in each pair of caster mounting holes to the angular bisector of the rounded corner portion 11 are equal or unequal, and can be set by technicians according to actual needs.

[0044] One of the necessary installation holes 121 is set as an adjustment hole 1211, which is an elongated hole. The adjustment hole 1211 extends along the direction of the center line connecting the two necessary installation holes, and is used to adjust the position of the screw when the caster 300 is installed, so as to facilitate the installation of the caster 300.

[0045] Furthermore, a pair of reinforcement holes 13 are also formed on the seat plate 10. The reinforcement holes 13 are used to pass through screws to connect with the bottom plate of the storage box body, enhancing the reliability of the connection between the mounting seat 100 and the storage box body, and preventing the mounting seat 100 from separating from the storage box body during use. It can be understood that when reinforcement is required, corresponding holes need to be drilled on the storage box body. These holes can be set by the manufacturer when the storage box is sold, or can be drilled by the user according to needs.

[0046] This pair of reinforcement holes 13 are symmetric about the angular bisector of the rounded portion 11 and are respectively arranged near the ends of the two hooks 20 that are far away from each other to improve the reinforcement effect.

[0047] Please refer to Figures 3 - 5 , the storage box includes a storage box body 200, a mounting seat 100 installed on the bottom surface of the storage box body 200 at the corner end, and a caster 300 installed on the mounting seat 100. The skirt 210 is provided at the bottom end of the storage box body 200. Since the mounting seat 100 is detachably connected between the storage box body and the caster 300, the detachable installation of the caster 300 is realized through the mounting seat 100. The caster 300 can be installed on the storage box to facilitate the movement of the storage box. After the movement of the storage box is completed, the caster 300 can be removed and recycled, or the caster 300 can be replaced according to needs when the caster 300 is damaged, without the need to discard the entire storage box, reducing costs.
