Description

Technical Field

[0001] This application belongs to the field of storage box manufacturing technology, specifically a storage box tray with two-way wheels. Background Technology

[0002] Traditional storage boxes lack wheels, making them inconvenient to move. Furthermore, whether for home or industrial use, storage boxes, once full, need to be placed on shelves or cabinets. Many cabinets or shelves hold numerous storage boxes, so retrieving a specific box requires pulling it out like a drawer. Since these boxes lack wheels, pushing and pulling them out is very inconvenient and can even damage them. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by using a wheel connector with an X-direction and a Y-direction moving engagement part at the bottom of the storage box. This allows for the installation of rolling wheels at the bottom of the storage box via the wheel connector, facilitating the pushing and pulling of the storage box during the process of taking it out and putting it in. This solves the problem that current storage boxes are inconvenient to push in and pull out, and may even cause damage to the storage box.

[0004] The above-mentioned technical objective of this application is achieved through the following technical solution: A storage box with two-way wheels includes a box body and rolling wheels. The opening of the box body faces upward. Each of the four corners of the lower surface of the box body is provided with a wheel catch. Each wheel catch is detachably fitted with a rolling wheel. The wheel catch has an X-direction moving catch part and a Y-direction moving catch part, both of which can catch the rolling wheel. The center of gravity of the box body is located within the quadrilateral formed by the four wheel catches as vertices.

[0005] Preferably, each of the snap-fit ​​devices is a rectangular tube, the upper end of which is fixedly connected to the lower surface of the box body. The cross-section of the rectangular tube is rectangular, and each side wall of the lower end of the rectangular tube is provided with a mounting groove. The axes of the mounting grooves on two opposite side walls of the same rectangular tube are on the same straight line. Each pair of mounting grooves on the rectangular tube with their axes on the same straight line is a snap-fit ​​part that moves in the X direction, and the other pair is a snap-fit ​​part that moves in the Y direction. The axles on both sides of the rolling wheel are each located in a mounting groove. The distance from the lower end of the rectangular tube to the bottom of the mounting groove is less than the radius of the rolling wheel. The mounting groove is provided with an axle locking structure.

[0006] Preferably, the rectangular tube is elastic, the wheel axle locking structure includes a protrusion, and a protrusion is provided on each of the two inner sidewalls at the opening of the mounting groove.

[0007] Preferably, the cross-section of the mounting groove is arc-shaped, the central angle of the arc is greater than 180°, and the opening of the arc faces away from the box body.

[0008] Preferably, the wheel axle locking structure includes a socket and a bolt. Each side wall at the lower end of the rectangular tube is provided with a socket, and the axis of each socket corresponds to the side wall of the socket. The socket and the bolt cooperate. When the length of the bolt is greater than the side length of the cross-section of the rectangular tube, when the bolt is inserted into the socket, it can prevent the wheel axle of the rolling wheel from falling out of the mounting groove.

[0009] Preferably, a handle is provided on one outer side wall of the box body near the opening of the box body, and a rectangular through hole is provided on the other side wall of the box body opposite to the handle near the opening of the box body.

[0010] The beneficial effects of this application are: This application employs a wheel connector with an X-direction and a Y-direction moving engagement part at the bottom of the storage box. This allows for the installation of rolling wheels at the bottom of the storage box via the wheel connector, facilitating the pushing and pulling of the storage box during the process of taking it out and placing it in. This solves the problem that current storage boxes are inconvenient to push in and pull out, and may even cause damage to the storage box. Attached Figure Description

[0013] like Figure 1-5As shown, a storage box with bidirectional wheels includes a box body 1 and rolling wheels 2. The opening of the box body 1 faces upward. Each of the four corners of the lower surface of the box body 1 is provided with a wheel catch. Each wheel catch is detachably fitted with a rolling wheel 2. The wheel catch has an X-direction moving catch part and a Y-direction moving catch part, both of which can catch the rolling wheel 2. The center of gravity of the box body 1 is located within the quadrilateral formed by the four wheel catches as vertices.

[0014] In this application, during use, the roller 2 is mounted on the wheel connector, after which the box body 1 can be moved. If the direction of movement of the box body 1 is the length direction of the box body 1, then the roller 2 is mounted on the Y-direction moving connector, such as... Figure 4 As shown, the arrangement of the box body 1's center of gravity within the quadrilateral formed by the four wheel catches ensures the stability of the box body 1. Conversely, if the box body 1 moves in the width direction, the rolling wheels 2 are mounted on the X-direction moving catch, as shown. Figure 2 As shown.

[0015] As a preferred embodiment, each of the snap-fit ​​devices is a rectangular tube 3, the upper end of which is fixedly connected to the lower surface of the box body 1. The rectangular tube 3 has a rectangular cross-section, and each side wall of the lower end of the rectangular tube 3 is provided with a mounting groove 4. The axes of the mounting grooves 4 on two opposite side walls of the same rectangular tube 3 are on the same straight line. One pair of mounting grooves 4 on each rectangular tube 3 with their axes on the same straight line is a snap-fit ​​part that moves in the X direction, and the other pair is a snap-fit ​​part that moves in the Y direction. The axles on both sides of the rolling wheel 2 are each located in a mounting groove 4. The distance from the lower end of the rectangular tube 3 to the bottom of the mounting groove 4 is less than the radius of the rolling wheel 2. The mounting groove 4 is provided with an axle locking structure. With this configuration, when in use, the rolling wheel 2 is installed on the rectangular tube 3 so that the axle of the rolling wheel 2 is snapped into the mounting groove 4, thus allowing the box body 1 to move. This detachable design is quite convenient. Moreover, this design method is lower in cost than using casters, and the movement direction of the box body 1 is less likely to swing during movement.

[0016] As a preferred embodiment, the rectangular tube 3 is elastic, the wheel axle locking structure includes a protrusion 5, and a protrusion 5 is provided on each of the two inner sidewalls at the opening of the mounting groove 4. The protrusion 5 is provided to prevent the rolling wheel 2 from falling out of the mounting groove 4. At the same time, its elasticity also facilitates the installation of the rolling wheel 2.

[0017] As a preferred embodiment, the cross-section of the mounting groove 4 is arc-shaped, with a central angle greater than 180°, and the opening of the arc faces away from the box body 1. This design increases the contact area between the axle of the rolling wheel 2 and the mounting groove 4, further preventing the axle of the rolling wheel 2 from falling out of the mounting groove 4 during movement.

[0018] As a preferred method, such as Figure 5 As shown, the wheel axle locking structure includes a socket 6 and a bolt 7. A socket 6 is provided through each side wall of the lower end of the rectangular tube 3. The axis of each socket 6 corresponds to the side wall of that socket 6. The socket 6 engages with the bolt 7. When the length of the bolt 7 is greater than the side length of the cross-section of the rectangular tube 3, and when the bolt 7 is inserted into the socket 6, it prevents the wheel axle of the rolling wheel 2 from falling out of the mounting groove 4. With this configuration, without the protrusion 5, after the wheel axle of the rolling wheel 2 is placed into the mounting groove 4, the bolt 7 locks it in place, thus preventing the rolling wheel 2 from falling out of the mounting groove 4.

[0019] As a preferred embodiment, a handle 8 is provided on one outer side wall of the box body 1 near the opening of the box body 1, and a rectangular through hole 9 is provided on the other side wall of the box body 1 opposite to the handle 8 near the opening of the box body 1. This arrangement allows the user to grasp the handle 8 with one hand and use the rectangular through hole 9 with the other hand to hold the box body 1. The rectangular through hole 9 does not increase the volume of the box body 1; therefore, if the box body 1 needs to be inserted into a cabinet, the end with the rectangular through hole 9 can be inserted into the cabinet.
