Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of luggage parts, in particular to an easily replaceable rod-inserting wheel. Background Art
[0002] A caster with a stem is a type of caster that can be mounted directly onto equipment or furniture using a stem, providing stable support and mobility. The stem design makes installation quick and easy; typically, installation is completed by simply inserting the stem into the corresponding hole in the equipment or furniture.
[0003] Patent publication number CN220517897U discloses a wheel body easily replaceable plug-in rod wheel, which includes a wheel frame, a plug-in rod, a wheel body and a cross bar. A circular hole is opened on the top of the wheel frame, and through holes are opened on both sides of the wheel frame. The cross bar is arranged in the two through holes. A second shaft is provided between the wheel body and the cross bar to enable the two to rotate relative to each other. The device causes two V-shaped rockers to rotate synchronously through a connecting rod. One end of the V-shaped rocker contacts a contact plate, causing the contact plate to move up, and the plug-in rods on the two contact plates to move up synchronously and disengage from the plug-in hole. The spring is compressed, and at this time the cross bar can be pulled out of the two through holes, and the cross bar is disengaged from the wheel body, thereby removing the wheel body. It can be seen that the entire installation and disassembly process is simple and quick, and no other tools are required for operation.
[0004] However, the device has the problem that when disassembling the wheel body, the connecting rod must first be pressed down, and then the V-shaped rocker is used to move the connecting rod up to move it out of the socket in the cross bar. Only then can the wheel body be removed by moving the cross bar out. This results in that when installing, the wheel body needs to be installed first, and after aligning and inserting the cross bar into the wheel body, the connecting rod must be kept in an upward state, and the angle of the cross bar must be adjusted so that the socket and the connecting rod are aligned to complete the wheel body installation. The process is cumbersome and complicated, which is not conducive to the rapid disassembly, maintenance and replacement of the wheel body. For this reason, a wheel body easy-to-replace plug-in wheel is proposed to solve the problem that the existing plug-in wheel is difficult to quickly disassemble, repair and replace the wheel body.

[0015] (3) Beneficial effects
[0016] 1. The wheel body of the easy-to-replace plug-in rod wheel moves the connecting rod to the left through the connecting plate, and then moves the limit block in the limit groove to the left to release the restriction of the rotating shaft. The wheel body moves out of the groove by itself. During installation, the rotating shaft is directly moved into the installation groove. During the process, the limit block moves into the limit groove with the help of the guide slope to compress the spring. After the rotating shaft reaches the top of the installation groove, the elastic limit block blocks the bottom of the rotating shaft to complete the installation, which solves the problem that the existing plug-in rod wheel is difficult to quickly disassemble, repair and replace the wheel body.
[0017] 2. The wheel body of the easily replaceable plug-in rod wheel is driven by the knob to rotate the screw, and cooperates with the U-shaped moving block in the moving groove connected to the screw rotation, so that the U-shaped moving block moves toward the direction of the wheel body, and the anti-slip pad is squeezed with the wheel body, so that the wheel body can be limited, which is convenient for position restriction of the equipment or furniture installed with the plug-in rod wheel, thereby improving the stability of the equipment or furniture when in use.
