[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Figure 1 A drawer 100 in one embodiment is shown. In this embodiment, the drawer 100 is used in conjunction with a piece of furniture 200. In this embodiment, the piece of furniture 200 is a bed. Specifically, below the bed board 210 of the piece of furniture 200 is a receiving space 220, in which the drawer 100 is received. When necessary, the drawer 100 can be pulled out of the receiving space 220 by a user, thereby allowing the user to take out the required items from the drawer 100 or put the items into the drawer 100. Thereafter, the user can push the drawer 100 so that it is completely received in the receiving space 220. It is understandable that in other embodiments, the piece of furniture 200 can also be a sofa, a cabinet, etc.

[0023] refer to Figure 2 and Figure 3 In one embodiment, the drawer 100 includes a first side panel 110 and a second side panel 120 that are opposite and spaced from each other, and a third side panel 130 that is connected to the first side panel 110 and the second side panel 120. The drawer 100 also includes a fourth side panel 140 that is opposite to the third side panel 130, and the third side panel 130 and the fourth side panel 140 are respectively connected to opposite ends of the first side panel 110 and the second side panel 120. The drawer 100 also includes a bottom panel 150 that is located in a space surrounded by the first side panel 110, the second side panel 120, the third side panel 130, and the fourth side panel 140 and is connected to the four side panels.

[0024] refer to Figure 4 and Figure 5In one embodiment, a plurality of casters 300 are installed at different positions of the drawer 100, and the plurality of casters 300 support the drawer 100 and can drive the drawer 100 to move on a surface (e.g., a floor). The caster 300 includes a wheel 310 and a body 320. The body 320 can be a flat square plate. The body 320 has a top surface 321 and a bottom surface 322 facing each other. The top surface 321 faces the drawer 100, and the bottom surface 322 faces the surface (e.g., a floor), and the wheel 310 is fixed to the bottom surface 322.

[0025] In one embodiment, the caster 300 also includes a first protruding wall 330 and a second protruding wall 340, which protrude from the top surface 321 of the main body 320, and the first protruding wall 330 and the second protruding wall 340 are spaced apart from each other to form a first mounting groove 350, and the first mounting groove 350 is used to accommodate a portion of the bottom end of the first side panel 110 or the second side panel 120.

[0026] With such a configuration, when the caster 300 needs to be installed on the first side plate 110 or the second side plate 120, the user can face the first mounting groove 350 to the first side plate 110 or the second side plate 120, and then push the caster 300 toward the first side plate 110 or the second side plate 120 until a portion of the bottom end of the first side plate 110 or the second side plate 120 is accommodated in the first mounting groove 350. The width of the first mounting groove 350 (i.e., the distance between the opposing surfaces of the first protruding wall 330 and the second protruding wall 340) can be set to be equal to or slightly larger than the thickness of the first side plate 110 or the second side plate 120, so that the user can push the caster 300 to a desired position along the first side plate 110 or the second side plate 120. Thereafter, the user can use a fastener (e.g., a screw) to fix the body 320 to the first side plate 110 or the second side plate 120.

[0027] In one embodiment, the inner surface of the first mounting groove 350 is formed with a through hole for a fastener to pass through for fixing the caster 300 to the first side plate 110 or the second side plate 120. In this embodiment, the through hole is a through hole 323 formed on the main body 320 and is located between the first protruding wall 330 and the second protruding wall 340. In other words, the "inner surface of the first mounting groove 350" at this time refers to the surface of the top surface 321 of the main body 320 located on the first protruding wall 330 and the second protruding wall 340. In this embodiment, the end of the fastener (such as a screw) passes through the through hole 323 and extends into the bottom end of the first side plate 110 or the second side plate 120, thereby fixing the main body 320 to the first side plate 110 or the second side plate 120.

[0028] It is understandable that in other embodiments, the “inner surface of the first mounting groove 350” may refer to the opposite surfaces of the first protruding wall 330 and the second protruding wall 340, that is, the through hole sequentially passes through the first protruding wall 330 and the second protruding wall 340. In this case, it is necessary that a fastener (such as a screw) passes through the first side plate 110 or the second side plate 120 to fix the first protruding wall 330 and the second protruding wall 340 to the first side plate 110 or the second side plate 120.

[0029] The above-mentioned embodiment provides a caster with a single mounting groove 350 , and the mounting groove 350 needs to extend from one end of the main body 320 to the other opposite end, that is, the mounting groove 350 is a straight groove with two ends open.

[0030] In one embodiment, the caster 300 further includes a third protruding wall 360 and a fourth protruding wall 370, the third protruding wall 360 and the fourth protruding wall 370 protruding from the top surface 321 of the main body 320, the third protruding wall 360 and the fourth protruding wall 370 are spaced apart from each other to form a second mounting groove 380, and the second mounting groove 380 is used to receive a portion of the bottom end of the third side plate 130. With such a configuration, the caster 300 can be installed at a corner where the first side plate 110 and the third side plate 130 intersect. In this case, a portion of the bottom end of the first side plate 110 is received in the first mounting groove 350, and a portion of the bottom end of the third side plate 130 is received in the second mounting groove 380. Similar to the first mounting groove 350, the inner surface of the second mounting groove 380 is formed with a through hole 324 for a fastener for fixing the caster 300 to pass through. With such a structure, the main body 320 can be fixed to the first side plate 110 and the third side plate 130 by fasteners, thereby facilitating the fastening of the caster 300 to the drawer 100 .

[0031] It is understandable that the caster 300 can also be installed at the corner where the second side plate 120 intersects the third side plate 130. At this time, a portion of the bottom end of the third side plate 130 is received in the first mounting groove 350, and a portion of the bottom end of the second side plate 120 is received in the second mounting groove 380.

[0032] In the above-mentioned embodiment, whether the caster 300 has a single first mounting groove 350 or the caster 300 also has a second mounting groove 380, when the caster 300 is fixed to the drawer 100, the first protruding wall 330 and / or the third protruding wall 360 are located on the outer side of the side panel of the drawer 100, and the second protruding wall 340 and the fourth protruding wall 360 are located on the inner side of the side panel of the drawer 100, and the top end of the second protruding wall 340 and the top end of the fourth protruding wall 360 are in conflict with the bottom plate 150 of the drawer 100. In order to prevent the bottom plate 150 from interfering with the second protruding wall 340 and / or the fourth protruding wall 360, the bottom ends of the bottom plate 150 and the first side plate 110, the second side plate 120 and the third side plate 130 are not flush, but are retracted inward by a small distance, so that the bottom plate 150 and the first side plate 110, the second side plate 120 and the third side plate 130 form a shallow groove 160, thereby avoiding the above-mentioned interference.

[0033] In one embodiment, the first protruding wall 330 is close to the first edge 325 of the main body 320, and the third protruding wall 360 is close to the second edge 326 of the main body 320 intersecting the first edge 325. When the selected first side plate 110 / second side plate 120 can be clamped between the first protruding wall 330 and the second protruding wall 340 or between the third protruding wall 360 and the fourth protruding wall 370, the distance A (see Figure 4 ) is not less than the distance a between the third protruding wall 360 and the fourth protruding wall 370 (see Figure 4 ), the distance B between the end 361 of the third protruding wall 360 close to the first protruding wall 330 and the first protruding wall 330 (see Figure 4 ) is not less than the distance b between the first protruding wall 330 and the second protruding wall 340 (see Figure 4 ). Through such an arrangement, a notch 390 is formed near the end 331 of the first protruding wall 330 and the end 361 of the third protruding wall 360. In this way, the caster 300 can also be fixed at the corner where the first side plate 110 / the second side plate 120 and the fourth side plate 140 intersect as needed, because the existence of the notch 390 prevents the first protruding wall 330 and the third protruding wall 360 from interfering with the first side plate 110 / the second side plate 120.

[0034] In one embodiment, the caster 300 further includes a fifth protruding wall 400 and a sixth protruding wall 410, wherein the fifth protruding wall 400 is opposite to the second protruding wall 340, and the sixth protruding wall 410 is opposite to the fourth protruding wall 370. The top end of the fifth protruding wall 400 extends with a first embedded sheet 420 in a direction away from the second protruding wall 340, and the top end of the sixth protruding wall 410 extends with a second embedded sheet 430 in a direction away from the fourth protruding wall 370. Referring to the figure, the inner surface 141 of the fourth side plate 140 facing the third side plate 13 is provided with a slot 142 (see FIG. 142 ) for accommodating the first embedded sheet 420 and the second embedded sheet 430. Figure 6 ). When the caster 300 is fixed at the corner where the first side plate 110 / the second side plate 120 and the fourth side plate 140 intersect, the first embedded piece 420 and the second embedded piece 430 are received in the slot. The cooperation between the first embedded piece 420 and the second embedded piece 430 and the slot can limit the movement of the caster 300 in the vertical direction, and combined with the fastener fixing the caster 300, the fastness of the caster 300 fixed to the drawer 100 can be increased.

[0035] In one embodiment, a protrusion 440 is provided in the space surrounded by the second protruding wall 340, the fourth protruding wall 370, the fifth protruding wall 400 and the sixth protruding wall 410. The protrusion 440 has the same height as the second protruding wall 340, the fourth protruding wall 370, the fifth protruding wall 400 and the sixth protruding wall 410. A through hole 441 for a fastener (such as a screw) to pass through is provided on the protrusion 440. A partition 170 is fixed to the surface of the bottom plate 150 facing the floor, and the protrusion 440 can be fixed to the partition 170 by a fastener passing through the through hole 441.

[0036] Through the above-mentioned structure, the caster 300 can be fixed at different positions of the drawer 100 according to different needs, has good adaptability, can be fixed on the side panel of the drawer 100, has a simple structure, and is conducive to reducing costs.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
