Abstract

The utility model provides a fixing device for shelf which can adjust the height, and consists of a supporting pipe component, a socket plate, an elastic O-shaped loop, a cross beam, an upright post and so on; the inner diameter of the lower part of the supporting pipe component gradually increases to shape a trumpet, and the inner diameter of the upper part of the supporting pipe component is a little longer than the diameter of the upright post and the diameter of the suit, and the outer diameter of the upright post is a little shorter than the inner diameter of the bigger caliber end of the supporting pipe component; The outer surface of the supporting pipe fitting is welded with the upright post which is enclosed by the elastic O-shaped loop, and the inner diameter of the elastic O-shaped loop is a little shorter than the diameter of the socket plate of the upright post, and the end of the cross beam is inserted into the socket plate. Through the cross beam or the horizontal beam of the shelf, the utility model can freely adjust the height so as to further adjust the height of the articles plate or the articles frame, thereby being convenient for placing the articles and promising no damage to the whole intensity of the shelf; besides, the utility model has advantages of simple structure and easy producing.

Description

A kind of fixture of rack

Technical field

The utility model relates to a kind of fixture of rack, particularly a kind of fixture of self height-adjustable rack.

Background technology

Rack generally has a plurality of interlayers, can put a plurality of article simultaneously.The structure of common rack is to be horizontally set with some crossbeams between several root posts, puts the glove plate on the crossbeam.Fixed form between crossbeam and the column is welding or locking, also there is end with crossbeam to be designed to plug-in type, be plugged on the frid that welds with column, no matter which kind of fixed form, the distance of in the vertical direction is fixed between each crossbeam, can not regulate the distance between the crossbeam arbitrarily, therefore the article of putting also are restricted.A kind of rack is arranged in addition, on column, be provided with a plurality of holes, crossbeam is fixed on the hole by sub-assembly, because establish at various height in the hole, therefore can regulate the height of crossbeam, but this rack manufacturing is very time-consuming, the cost height, and the existence in a plurality of holes reduced the intensity of column and attractive in appearance, and the quantity in hole also is limited, can not regulate height arbitrarily.Generally speaking, existing rack is because the fixture design is unreasonable, and therefore inconvenient article puts.

The utility model content

The utility model provides a kind of fixture of rack, makes the crossbeam of rack can regulate height arbitrarily, and simple in structure, makes easily.

The utility model comprises support tubes, frid, elasticity O type circle, crossbeam, column etc.; The internal diameter of support tubes the latter half increases gradually, is horn-like, and the internal diameter on its top is slightly larger than the diameter of column, is sleeved on the column to movingly; Also be with an elasticity O type circle below support tubes, the internal diameter of elasticity O type circle is slightly less than the diameter of column, and external diameter is slightly less than the internal diameter of support tubes big opening end; The outer surface of support tubes is welded with frid, and the end of crossbeam and frid form the relation of pegging graft.

Frid described in the utility model is a U type structure, and its positive top has the groove of two strips, and there are two plates that match with double flute on the frid end of crossbeam.

The front of frid described in the utility model has three through holes of vertically arranging, and there are three three plates that match with three holes on the frid end of crossbeam.

180 degree directions are welded with the i.e. type of two frids on the support tubes circumference described in the utility model.

It is that L type or three frids are that T type or four frids are ten types that 90 degree of being separated by on the support tubes circumference described in the utility model are welded with two frids.

Support tubes described in the utility model is cylinder type, square tube type, polygon cartridge type, and corresponding pillar is cylinder, square body or polygonal cylinder.

Owing to take said structure, the utility model do not destroy on the column intensity based can the free adjustment crossbeam, the height of longeron, and then adjust the height of glove plate, made things convenient for putting of article; Promptly the glove plate level can be placed, also the glove plate can be tilted place.Utilize the utility model can make A type twin columns supporting structure rack, also can make Type B four post supporting structure racks; The utility model can be organized any combination more, extends as required.

Description of drawings

Accompanying drawing 1 is embodiment 1 structural representation of the present utility model;

Accompanying drawing 2 is embodiment 2 structural representations of the present utility model.

Specific embodiment

Embodiment 1, and with reference to accompanying drawing 1, the fixture of a kind of rack of the utility model comprises support tubes 1, elasticity O type circle 3, frid 2, crossbeam joint 4, column 5.Two frids 2 are the outer surface that 90 degree L types are welded on support tubes 1 respectively; Frid 2 is a U type structure, and the top in its front 21 has the groove 22 of two strips, and all there are two plates 4161 that match with double flute 22 on the frid 2 end of crossbeam joint 4, longeron joint 6; The internal diameter on support tubes 1 top is slightly larger than the diameter of column 5, and internal diameter of support tubes 1 the latter half and external diameter all increase gradually, are horn-like; The internal diameter of elasticity O type circle 3 is slightly less than the diameter of column 5, and its external diameter is slightly less than the internal diameter of support tubes 1 big opening end.

When installing and using, elasticity O type circle 3 is set on the column 5, because its retractility, elasticity O type circle 3 is fastened on desired location height on the column 5; Support tubes 1 cover is inserted in elasticity O type circle 3 tops; And from elasticity O type circle 3 tops to lower slider, when elasticity O type circle 3 is positioned at the horn-like opening of support tubes 1 bottom, be subjected to the extruding of support tubes 1 madial wall and column 5 outer surfaces, produce certain force of strain, because support tubes 1 madial wall bottom is the inclined-plane, when support tubes 1 is downward more, the extruding that elasticity O type circle 3 is subjected to is big more, the tension force that produces is also big more, the frictional force that makes progress that support tubes 1 is subjected to is also big more, when this frictional force arrived to a certain degree greatly, support tubes 1 no longer glided, and also just has been fixed on the column 5.

Present embodiment can be the Type B shelf with four post supporting structure racks, at least form by four root posts 5, the bottom of column 5 and top all have some spliced eyes, the front end of cross bar and vertical pole inserts in the spliced eye respectively, fixes, be with several support tubes 1 and elasticity O type circle 3 at the middle part of column 5, to dispose several glove plate or baskets.

Embodiment two, with reference to accompanying drawing 2, difference from Example 1 is: 180 degree directions are welded with two frids 2 on support tubes 1 circumference, the front of frid 2 has three through holes of vertically arranging 23, there are three three plates 42 that match with three through holes 23 on the frid 2 end of crossbeam joint 4, so the end of crossbeam joint 4 can be plugged on the frid 2.

If regulate the height of glove plate, only need to regulate elasticity O type circle 3 position on column 5 and just can realize.

Present embodiment can be used for twin columns supporting structure rack, be A type shelf, have at least two root posts 5 to form, have in the top of column 5 and bottom and all to have some spliced eyes, the cross bar front end inserts in the spliced eye respectively, fixes, be with several support tubes 1 and elasticity O type circle 3 at the middle part of column 5, to dispose several glove plate or baskets.

In sum, the utility model makes the crossbeam of rack or longeron can regulate height arbitrarily, and then arranges the height of thing plate or glove frame, makes things convenient for putting of article, does not destroy the rack integral intensity, and simple in structure, produces easily.
