Abstract: An adjustable rack trolley has a base seat, a top seat, a stand, and a supporting rod. The base seat has multiple sets of latching grooves arranged at spaced intervals along the first direction. The stand is connected with the base seat and the top seat, and has a first frame and a second frame pivotally connected to each other. An end of the first frame is pivotally connected to the first end of the base seat, and an end of the second frame is selectively engaged in a set of the latching grooves. An end of the top seat is pivotally connected to the top of the stand. One end of the supporting rod is pivotally connected to the top seat, and the other end of the supporting rod is detachably connected with the stand.

Abstract: A rack assembly has two side racks, two rails, and at least one sub-rack. The rails are mounted between the side racks and include a front rail and a rear rail parallel with each other. Each rail has an opening in a bottom of the rail. The at least one sub-rack is slidable along the rails and each sub-rack has a rack frame, a connection rod, and at least one supporting member. The rack frame has at least one front rod and at least one rear rod. Each front rod has an extension rod mounted retractably on a top of the front rod and having a front wheel.

Abstract: A rack assembly having two side racks, two rails, and at least one sub-rack, wherein the rails are mounted between the side racks and include a front rail and a rear rail lower than the front rail. Each rail has an opening in a side of the rail, with the opening of the front rail defined in a bottom of the front rail and the opening of the rear rail defined in the rear rail at a side facing the front rail. The at least one sub-rack has a rack frame, a connection rod, and at least one supporting member and is slidable along the rails The rack frame has at least one front rod and at least one rear rod wherein each front rod has an extension rod mounted retractably on a top of the front rod and a front wheel.

Abstract: A rack has a linear guide and a braking module. The braking module has a braking device, a braking block, a transmission shaft and a elastic device. A central end of the braking device expands toward one side of a slide rest so as to allow the control end to extend outwardly of the slide rest. The transmission shaft drives the braking block. The braking block touches the rails so as to achieve a braking effect.

Abstract: The present invention provides a rack with linear guide based on the structure of the invention of a parent application. The invention includes the braking module comprised of a braking device, braking block, transmission shaft and elastic device. The control end of the braking device expands towards one side of the slide rest to make the control end expose outside the rack for better control. The invention uses the transmission shaft to drive the braking block and uses the feature that the transmission shaft moves stably inside the internal base for durability. The braking block touches the rails to achieve the braking effect, and achieve a forceful braking effect.

Abstract: The present invention provides an improved structure of the assembled shelf. The invention includes a main frame having two vertical side racks and several sets of shelves. Each shelf is placed inside the two vertical side racks. There is a vertical bar of the vertical side rack, which includes a main bar and at least one secondary bar. The secondary bar is placed on the sides of the main bar, and the space is formed by the distance of the horizontal bar. A frame is placed on both sides of the shelf, and a vertical groove is on both ends. The groove can be connected to the main and secondary bars. By so doing, each shelf and two vertical side racks do not have to use other components to be positioned and are compatible with a common extension, such as vertical side rack, to make the invention more practical.

Abstract: The storage cabinet structure includes a ?-shaped bent edge formed where the right and left sides of the back board connect to the side boards, and positioning holes are placed on the front sides of the ?-shaped bent edge from top to bottom; a vertical protruding strip placed on the inner wall on the front side of the side boards; and the shelf support of the supporting rack used to assemble the positioning holes and the back board for supporting the shelf. A frame of the bottom board can be placed on the top and bottom end of the side boards and back board, and its corresponding inner side is pushed against the concave edge to make the top and bottom ends of the top and bottom board and side boards. The storage cabinet that is easy to assemble, and has stronger structure is provided.

Abstract: A sliding rack apparatus having a rack body having supported on a slide rest and movable along a pair of slide tracks. The slide rest has a pair of rollers with a rut therebetween. The slide tracks have a convex edge in a center thereof so as to extend in the rut between the rollers. A braking device has a T-shaped plate with a rim that is pivotable between a first portion engaging the convex edge and a second position free of the convex edge.
