[0028] The present application is described with reference to the attached drawings in which various embodiments of the present application are shown. The description is made in connection with the drawings in which the various embodiments of the present application are shown. The description includes various specific details to assist in understanding the various embodiments of the present application. These details are merely exemplary. It will be apparent to those skilled in the art that various changes and modifications can be made thereto without departing from the scope and spirit of the present application.

[0029] In the description of the present application, the orientation description, such as the orientation or position relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0030] It should be understood that when one element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element, or there can be an intervening element (e.g., a third element) between the element and the other element.

[0031] The embodiment of the present application provides a high-strength caster support, as shown in the drawings, which comprises a support seat 210 and two arms 220, the top ends of the two arms 220 are connected to the support seat 210, and the two arms 220 extend downward from the support seat 210. Figures 1-3 The two arms 220 each comprise a bending structure 221 at the top end thereof, the bending structures 221 on the two arms 220 are located on the same side edge of each, i.e. the bending structures 221 on the two arms 220 are located at the side edge of each, and are on the same side edge, so as to Figure 1 For example, the bending structures 221 on the two arms 220 are located at the side edge of the front side of the arm 220. The bending structures 221 on the two arms 220 are connected to the support seat 210.

[0032] In this embodiment, due to the presence of the bending structure 221, the width of the top end of the arm 220 is increased, accordingly, the contact of the top end of the arm 220 with the support seat 210 is more, the connecting area of the top end of the arm 220 with the support seat 210 can be increased, thereby improving the strength of the whole support and increasing the load bearing of the caster.

[0033] In some embodiments, the bending structures 221 on the two arms 220 bend towards each other, so that the bending structures 221 are relatively not protruding from the outer side of the arms 220, and are in a state of inwardly bending and shrinking. During movement, the caster is not easy to collide with external objects, so as to avoid damage to the support and scratches on the collided objects by the bending structures 221.

[0034] In some embodiments, the outer side of the top end of each of the two arms 220 is provided with an outwardly protruding ridge 222, and the ridge 222 is connected with the support seat. The ridge 222 is equivalent to increasing the thickness of the top end of the arm 220, and the top end of the arm 220 is in contact with the support seat 210 more, so as to further improve the strength of the whole support and increase the load bearing of the caster.

[0035] In the present embodiment, the outer side of the ridge 222 can be arc-shaped, which is relatively smooth, so that the damage to the ridge 222 caused by collision with external objects is reduced, and scratches on the collided objects by the ridge 222 are avoided. The ridge 222 can be integrally formed with the arm 220, so as to facilitate overall manufacturing and strengthen the connection strength between the ridge 222 and the arm 220.

[0036] In some embodiments, each of the two arms 220 further comprises a curved portion 223 and a flat plate portion 224. The curved portion 223 is arc-shaped, and the flat plate portion 224 is flat. The top end of the curved portion 223 is connected with the support seat 210, the flat plate portion 224 is located on one side of the curved portion 223 and connected with the curved portion 223, and the bending structure 221 is located on the top of the flat plate portion 224.

[0037] Compared with the flat plate structure, the width of the arc-shaped curved portion 223 is larger, which is equivalent to increasing the width of the top end of the arm 220. Accordingly, the top end of the arm 220 is in contact with the support seat 210 further more, so as to further increase the connection area between the top end of the arm 220 and the support seat 210, thereby improving the strength of the whole support and increasing the load bearing of the caster.

[0038] Further, the bending structure 221, the curved portion 223 and the flat plate portion 224 are integrally formed, so as to facilitate overall manufacturing and strengthen the connection strength between each other.

[0039] In some embodiments, each of the two arms 220 is provided with a through brake mounting hole 225, and the brake mounting hole 225 is used for installing a brake assembly, so that the caster has a brake function.

[0040] In some embodiments, the support seat 210 is disc-shaped, and the top surface of the support seat 210 is provided with a lower ball groove 211. The lower ball groove 211 can accommodate a ball, so as to clamp the ball with a top plate above the support, and the support can rotate relative to the top plate to form a universal caster.

[0041] The bending structure 221 and the bending part 223 of the above embodiment can adapt the disc-shaped bracket seat 210, so that the whole top end of the support arm 220 can be connected with the bracket seat 210.

[0042] The embodiment of the utility model provides a trundle, such as Figures 4-6 As shown, including wheel body 100 and high strength trundle support of any above embodiment, the specific description of high strength trundle support can refer to the above embodiment, and here is no more. Wheel body 100 is arranged between two support arms 220 and is rotatably connected with two support arms 220, whereby wheel body 100 can rotate relative to the bracket.

[0043] In some embodiments, the two sides of wheel body 100 are provided with dust covers 130, and the dust covers 130 are located between the support arms 220 and the wheel body 100. The dust covers 130 can reduce the entry of dust and other impurities into the inside of the wheel body 100, including the smooth rotation of the trundle, which is especially suitable for use in a high-dust environment. The two support arms 220 can limit the dust covers 130 from the two sides, preventing the dust covers 130 from falling off.

[0044] Further, the outer side of the dust cover 130 includes a flat part 131 located at the center position, and the periphery of the flat part 131 can be arc-shaped. The flat part 131 is a plane, and the arc-shaped part is an arc surface. The flat part 131 is provided with a boss 132 protruding from the flat part 131, and the boss 131 is provided with a through hole 133 penetrating the dust cover 130.

[0045] The assembly of the bracket and the wheel body 100 is usually dependent on the installation screw 230 and the nut. The installation screw 230 penetrates the through holes 133 of the two support arms 220, the two dust covers 130 and the wheel body 100. After locking the installation screw 230 and the nut, the support arm 220 of the bracket will be tightly attached to the boss 132 to clamp the boss 132, so that the boss 132 is deformed and recessed. Thus, the position of the periphery of the flat part 131 will be more closely contacted with the support arm 220 of the bracket to further reduce the entry of dust and other impurities into the inside of the wheel body 100 and improve the dustproof effect.

[0046] In some embodiments, a brake assembly 300 is further included, which can limit the rotation of the wheel body 100 relative to the bracket to achieve the brake function. The brake assembly 300 can be installed on the support arm 220 through the brake mounting hole of the above embodiment.
