Abstract

The utility model relates to a height-adjustable multi-layer kitchen-table rack, which is provided with two support pipes. A net sheet is movably connected between the support pipes through a connecting sleeve. The structures of the support pipes are characterized in that the two pipes are connected with each other in a sliding manner through a locking structure. The pipe 8 freely stretches and elongates in the pipe 3. The integral height is determined by the pipe 8 through a molding piece in a lock and a molding piece outside the lock and then swelled tensely. When the pipe 8 rotates corresponding to the pipe 3, the molding piece in the lock moves on the molding piece outside the lock to increase the friction between the molding piece in the lock and the pipe 3 and play a locking function. When the met sheet is retracted, the connecting sleeve is turned upwards taking a screw as a rotating center. The downward slide of the net sheet is prevented through the engaging structures of gear teeth 221 and gear teeth 23. After a screw bolt 5 is locked to the screw 19, the spring can play a protective function on the gear teeth. The spring plays a strength adjusting function in the process of the rotation of the net sheet. Under the function of the force, the gear teeth of the net sheet can fix the net sheet at any angle within the range of the rotating angle of the net sheet. When the quantity of the connecting sleeves is increased, the quantity of the net sheet can be freely increased.

Description

Adjustable height multilayer kitchen stand

Technical field

The utility model relates to a kind of kitchen stand, is that a kind of can arbitrarily the expansion used specifically, and can fold again with the increase activity space, adjustable for height, net sheet to increase diminishbb kitchen article rack.

Background technology

In the room or the kitchen place thing, generally all adopt the estrade on cupboard or plane, cupboard is generally heavier and take very large space.Estrade, because be the cause on plane, the placed side can not be very big, otherwise can take very large space, like this, the thing of placement is just very limited.

Summary of the invention

The utility model is to provide a kind of adjustable height multilayer kitchen stand of folding and unfolding use, sanitation and hygiene arbitrarily.

A kind of adjustable height multilayer kitchen stand is characterized in that, the stay pipe structure is that pipe 8 is enclosed within the pipe 3 and is slidingly connected, and manages the outer plastic 16 of 8 one end fixed connection locks; Lock outer plastic 16 and connect plastic 17 in the lock by lower thread; Have a logical opening 171 on the plastic wall in the lock; Fine-adjustment outer 10 has center square column 102, is with spring 12 on the square column; The square column port has internal thread, and thread bush 13 is fixed in the internal thread by pad 14, screw 15; Thread bush 13 has external screw thread, is connected with the internal thread at cover 9 middle parts in the fine setting; Fine-adjustment outer 10 upper bracket 1 that is rotationally connected; Manage cover 9 in the fixedly connected fine setting of 8 other ends; Two stay pipes are arranged, be connected with net sheet 6 between the stay pipe, the net chip architecture is, has at least one hole on the net sheet plastic 22 of both sides, and pipe 24 is fixedly connected in the hole of both sides plastic; Adapter sleeve radially has plane 21; Adapter sleeve one side is a through hole 25, fixedly connected pipe 3 in the through hole; Through hole one side radial opening 41; Spring 18 is housed in the openend; The plastic 22 at net sheet two ends is placed on the adapter sleeve sagittal plane, and this end of each net sheet plastic has screw hole, and the screw hole diameter is greater than screw 19 diameters of thread; The net sheet is connected with bolt 5 by screw hole and the spring 18 that screw 19 passes on the plastic 22, and the relative adapter sleeve 4 of net sheet is rotationally connected; By screw 19 and being connected of bolt 5 adapter sleeve 4 is fixed on the pipe 3 simultaneously; On pipe 3, be fixed with an adapter sleeve 4 at least.

Pipe 8 is flexible arbitrarily the elongation in pipe 3, and whole height is determined by plastic 17 in the lock and the outer plastic 16 of lock by pipe 8, again by fine-adjustment outer 10 tensioners, when pipe 8 rotates with respect to pipe 3, plastic 17 is mobile on the plastic 16 outside lock in the lock, increases plastic 17 and the friction of managing 3 in the lock, plays the effect of locking.When net sheet 6 was packed up, adapter sleeve 4 was to turn on the pivot with screw 19, and the engaging structure by teeth 221 and teeth 23 works the net sheet downslide effect that prevents.

After bolt 5 and screw 19 lockings, spring 18 can play a protective role to teeth, and spring 18 plays the effect of strength of adjustment in net sheet 6 rotation processes, and net sheet teeth are can be in its rotational angle range under the effect of this power, arbitrarily angled fixed network sheet.

Increase adapter sleeve and can arbitrarily increase the net sheet.

The utility model has overcome the shortcoming of general kitchen article racks, and is simple in structure, can increase the net sheet according to different needs adjustment height, easy to use, launch, firmly can not topple over when packing up, occupy little space, the structure of multilayer, the placement of can following one's inclinations, article come into plain view and are presented at the moment.Stay pipe adopts pure stainless steel tube, the intensity height, and withstand load is big.The utility model is fit to the demand of different home.
