A kind of rack
Technical field
The utility model relates to a kind of rack.
Background technology
Commodity shelf structure in the past is four drift angle place welded sleeves at rack, be enclosed within on the support bar respectively, can arbitrarily increase the rack that the rack composition has sandwich construction, but when extending transversely, need the original rack of dismounting, on support bar, put the expansion rack again, assemble not conveniently, and the sleeve of the rack layer that increases newly can only stack with the former rack of corresponding place layer, causes the plane of two racks to stagger, not the plane transition, be not easy to place article.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of rack, and sleeve and rack are adopted the separate type design, can arbitrarily dismantle and expands rack, and is convenient and practical.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of rack, comprise rack and support bar, described support bar is provided with the tapered sleeve for the support rack, described tapered sleeve is tube-in-tube structure, be welded with fan-shaped support sheet on the cylindrical shell, fan-shaped support sheet is provided with two through holes, the reference column that corresponding rack corner position arranges, and each fan-shaped support sheet is the drift angle of support two networking framves simultaneously.
As further improvement in the technical proposal, the cylindrical shell of described tapered sleeve enlarges tapered from top to bottom gradually, is provided with spacing collar in the cylindrical shell.
As further improvement in the technical proposal, described support bar is provided with the bayonet slot ring distaff body of a plurality of differing heights.
As further improvement in the technical proposal, two fan-shaped support sheets of welding on the cylindrical shell of described tapered sleeve.
The beneficial effects of the utility model are, be used for placing rack and the tapered sleeve independent separate of article on the rack, tapered sleeve adopts fan-shaped support sheet to support rack, make things convenient for rack to expand, solve the asymmetric problem in two planes when rack was expanded in the past, be easy to remove and install, and tapered sleeve can weld two fan-shaped support sheets, on four direction, can support rack simultaneously, simple in structure, practical.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of tapered sleeve and spacing collar in the utility model.
Fig. 3 is the side schematic view of rack in the utility model.
Fig. 4 is the vertical view of another kind of embodiment in the utility model.
The specific embodiment
Referring to figs. 1 through shown in Figure 3, a kind of rack that the utility model provides, comprise rack 1 and support bar 2, described support bar 2 is provided with the tapered sleeve 3 for support rack 1, described tapered sleeve 3 is tube-in-tube structure, be welded with fan-shaped support sheet 31 on the cylindrical shell, fan-shaped support sheet 31 is provided with two through holes 32, the reference column 11 that corresponding rack 1 corner position arranges, each fan-shaped support sheet 31 is the drift angle of support two networking framves 1 simultaneously, only needing increases support bar 2 and tapered sleeve 3 respectively in two other drift angle place increase of rack 1, just can carry out horizontal expansion, and the 1 plane transition of expansion rack, and traditional rack can only be dismantled the rack 1 on upper strata earlier when expanding, be inserted in new rack 1 again and stagger with the rack 1 of corresponding place layer, can not extend on the plane, be not easy to place article.
Preferably, the cylindrical shell of described tapered sleeve 3 enlarges tapered from top to bottom gradually, be provided with spacing collar 32 in the cylindrical shell, the sidewall of spacing collar 32 closely contacts with cylinder inboard wall, when tapered sleeve 3 is inserted on the support bar 2, the extruding of the conical shell that spacing collar 32 is shunk gradually makes spacing collar 32 and the frictional force of support bar 2 strengthen, and utilizes frictional force to produce supporting role.
Preferably, described support bar 2 is provided with the draw-in groove 21 of a plurality of differing heights around the body of rod, and draw-in groove 21 can help to increase the resistance of spacing collar 32 on support bar 2, makes the support of tapered sleeve 3 more firm.
With reference to another kind of embodiment schematic diagram shown in Figure 4, can be welded with two fan-shaped support sheets 31 on the described tapered sleeve 3 simultaneously, each tapered sleeve 3 supports rack 1 respectively at four direction and expands like this, solve in the past with 1 liang of asymmetric problem in plane of one deck rack, make horizontal plane transition between rack 1, be convenient to place article, improve usage space, adopt the design of rack 1 and tapered sleeve 3 independent separate, make structure more simple and practical, for convenience detach and installation.
The above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
