A water tank for a dehumidifier includes a box body, a moving wheel, and a limit member. An installation groove is provided at a bottom of the box body, and a side wall of the installation groove being provided with a limit groove. The moving wheel is provided with a connection seat and a wheel body mounted at the connection seat. A side of the connection seat is configured to be installed in the limit groove. The limit member is disposed at least partially in the installation groove, so as to restrict the connection seat from sliding out of the limit groove.

The invention concerns a rolling device for a device to enable moving the device along a surface. The rolling device comprises a housing arranged for attachment to the device and a wheel support assembly arranged in the housing for carrying a wheel. The wheel support assembly comprises a wheel carrying member arranged for connection with the wheel, and a retainer element arranged for connection with the housing. The wheel carrying member comprises a deflective rib with an protrusion for releasable engagement with a groove of the retainer element to select the release or attachment between the wheel carrying member and the retainer element.

A wheel shock absorption structure and a child carrier having the wheel shock absorption structure, including a wheel shaft and a wheel seat connected with a frame, and a lower end of the wheel seat is rotatably connected with a wheel through the wheel shaft. Further including a shock absorber with an elastic structure, an upper end of the shock absorber is removably connected with an upper end of the wheel seat, and the shock absorber rotates synchronously along with the wheel seat; a lower end of the shock absorber is rotatably connected with the wheel shaft which is slidably connected with the lower end of the wheel seat. The shock absorber is driven by sliding of the wheel shaft to generate recoverable elastic deformation to provide damping and buffering. The bending deformation of the shock absorber ensures that the wheel shock absorption structure has a better shock absorbing effect.

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

The invention relates to a roller, in particular furniture roller, having a housing which is rotatably fastened, by means of a runner pin arranged vertically in an opening of the housing, to an object to be supported by the roller, wherein the runner pin has a first section which is arranged in the opening of the housing and a second section which projects beyond the housing. To create, in a simple and cost-effective manner, a runner pin which permanently prevents an undesired generation of noise as a result of relative movements between the runner pin and the object to be supported, it is proposed according to the invention that at least two annular grooves are provided in that section of the runner pin which projects beyond the housing, in which annular grooves in each case one elastic retaining ring is arranged without play.

A caster mounting portion has a mounting member housing portion which houses the mounting member, the mounting member has a rotary shaft portion which is pivotally supported in a bearing recessed portion in the mounting member housing portion, an abutment body in which the rotary shaft portion is provided at an eccentric position and which is displaced by rotation to be widened to close the inside of the mounting member housing portion, an upper locking piece which engages with a locking receiving portion of an opposed wall, a lower locking piece which abuts against the bottom face of a latching portion, and a locking stepped portion which is urged by a leading end of an elastic arm, climbing over the aforementioned latching portion, and engages with the latching portion.

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

A removable caster system includes a roller, a roller frame and a roller seat, the roller being positioned on the frame via a horizontal axis, the frame being inserted into the vertical shaft hole of the seat through the vertical shaft to form a detachable position; wherein a chute is installed on the upper surface with a trapezoidal stopper; a wire retainer is placed in the chute and is controlled by the movement of its narrowing section or the vertical axis to achieve removable function.

A connector for removably securing a first member having a hollow cavity with a second member such that a portion of the second member is removably fixed within the hollow cavity of the first member. The connector is configured to be inserted into the hollow cavity and has an outer bearing surface configured to rest in abutting engagement with the corresponding portion of the inner wall of the cavity when the connector is inserted into the cavity. The connector also includes an inner bearing surface that corresponds with a portion of an outer wall or surface of a second member and is additionally configured to accommodate the use of a force applicator to press the second member against the inner bearing surface and to press the outer bearing surface against the first member's inner wall to removably fix the second member and connector within the cavity.

Bicycle transport containers include a typically parallelepiped-shaped outer container. Retaining and/or receiving elements are provided inside the outer container for receiving bicycle elements such as bicycle frames, wheels and the like. In order to facilitate the transport of a bicycle transport container, the invention provides rolling elements on a bottom element of the outer container.
