Description

Technical Field

[0001] The present application relates to the technical field of paper shredders, and more specifically to a paper shredder with casters. Background Art

[0002] A shredder is a common office equipment used to destroy confidential paper materials or shred discarded paper to achieve the purpose of confidentiality. Traditional shredders are mainly composed of motors, gear systems, and shredders. The power is provided by the motor with a certain torque, which is amplified by the gear system and then transmitted to the shredder, so that the shredder rotates to shred the paper into pieces to achieve the purpose of shredding. Most of the existing shredders are stored in a corner of the office. For large offices, it is necessary to bring a lot of discarded documents to the shredder to work, or move the shredder to other locations. The shredder has a certain weight, and it is laborious and time-consuming to move it manually. Therefore, universal wheels are currently installed at the bottom of the shredder to enable the shredder to move. However, when the shredder is used at a fixed point, the universal wheels are difficult to be effectively stored, which affects actual use. In response to the above problems, a utility model patent with publication number: CN210357436U discloses an office paper shredding device, including a body, a paper storage chamber, a base, a double-toothed roller and a first motor. A baffle is arranged at the upper end of the paper storage chamber, and the baffle is connected to a track through a pulley. A driver is arranged in the body, a paper shredding inlet is arranged on the baffle, a block is arranged on the paper shredding inlet, a hydraulic pump is arranged under the baffle, and the hydraulic pump is connected to the block through a hydraulic rod. A vacuum pump is arranged on the baffle, and the vacuum pump is connected to the paper storage chamber through a pipeline. A storage groove symmetrically arranged along the center is opened at the lower end of the base, and a walking wheel is arranged in the storage groove. In this technical solution, a walking wheel mechanism that can be accommodated and arranged on the base is convenient for adjustment, and the base can realize the movement and positioning functions, which is convenient for the transportation and positioning of the body. However, the walking wheel mechanism has a complex structure and is difficult to disassemble and assemble, and there are still many inconveniences in actual use. Utility Model Content

[0003] The technical problem to be solved by the present application is to provide a paper shredder with casters, the casters of which can be moved and positioned for storage, and the structure is simple and the assembly and disassembly is labor-saving.

[0004] The present application provides a paper shredder with casters, comprising a body, casters are installed at the bottom of the body, a mounting seat adapted to the casters is provided at the bottom of the body, the casters are provided with connecting columns, the mounting seat is provided with a first connecting position and a second connecting position adapted to the connecting columns, the casters are connected to the first connecting position in a vertical direction through the connecting columns so as to be in an unfolded state relative to the body, the casters are connected to the second connecting position in a horizontal direction through the connecting columns so as to be in a folded state relative to the body, the mounting seat is connected to a locking piece, a limiting portion adapted to the locking piece is provided on the connecting column, and the locking piece is connected to the limiting portion so that the casters are limited on the mounting seat.

[0005] In the technical solution, by installing casters at the bottom of the body, the casters enable the shredder to be moved at will, and the movement is labor-saving and convenient. The casters are connected to the mounting seat at the bottom of the body through connecting columns. Conventional shredders are difficult to position and use after being connected to the casters. Taking into account the problem that the casters are difficult to store when the shredder is positioned for use, in the present solution, a first connecting position and a second connecting position are provided on the mounting seat. The connecting column is connected to the first connecting position in a vertical direction so as to be in an unfolded state relative to the body, and the casters can support the movement of the body. The connecting column is connected to the second connecting position in a horizontal direction so as to enable the casters to be in a folded state relative to the body, thereby positioning The body, the horizontal direction and the vertical direction in this application are based on the normal placement state of the shredder. The connecting column switches the first connection position and the second connection position to switch the unfolded state and the folded state of the shredder, which meets more usage requirements. Compared with ordinary shredders, it is necessary to plug the casters into the limiting structure, and the casters are more laborious to disassemble and assemble. However, this solution arranges a locking piece on the mounting seat and a limiting part for the locking piece to pass through on the connecting column. The locking piece passes through the limiting part to connect the mounting seat, thereby limiting the casters on the mounting seat to prevent the casters from detaching from the body.
