It is provided a plurality of grooves (4) engaging with the surface configuration of the pillars (3) of the racks (1) from respective corner on each connecting side of the plates (2) and the racks (1). The grooves (4) can surround pillars (3) firmly and make plates (2) tension firmly in the racks (1) when the plates (2) are mounted in the racks (1). It is allowed to adjust the width of the racks (1) at any moment and add additional support racks between the racks (1).

Description

BACKGROUND OF THE INVENTION

The present invention relates to a plate tensioning shelf, and in particular to a removable plate tensioning shelf for accommodating articles.
Normally, a tensioning shelf mainly comprises two lateral racks and several plates mounted between two lateral racks. The plates are fixed by Y-shaped joints which are welded to the plates and tighten the pillars of two lateral racks. This shelf's structure is complicated, and its manufacture is inconvenient either. During assembly, the distance between two lateral racks can not be adjusted at will, and it is also not allowed to add additional support racks to the shelf to enhance the weight-carrying capability of the plates. Thus, the intensity of the plates for a wider shelf is not enough to carry heavy weight. Therefore, the size and weight-carrying capability of the shelf are limited.

SUMMARY OF THE INVENTION

Having outlined the state of the prior art and its attendant shortages, it is an objective of the present invention to provide a plate tensioning shelf with simple structure, and with the plate tensioning shelf, it is allowed to adjust the width at any moment and add additional support racks to the shelf to enhance the weight-carrying capability. Furthermore, a plurality of shelves can be joined with each other.
The above objective of the present invention is achieved by the following technical solutions:
A plate tensioning shelf comprises two lateral racks and plates mounted between the racks. A plurality of grooves for engaging with the surface configuration of the pillars of the lateral racks are provided from corners of both sides of each of the plates. The grooves hold the pillars firmly and tighten the plates firmly in the racks when the plates are mounted in the racks.
Preferably, small crown-shaped protrusions are further provided in the grooves of the plates, and recesses corresponding to the protrusions are provided on the pillars. The protrusion is of a size adapted to be completely contained in the recess, and as a result, the plates are self-locked.
Preferably, the plate may be a plastic plate. The plastic plates can further facilitate the fastening and will not cause the surface damage of the pillars because of the better elasticity of the plastic plate.
With the above-described technical solutions, the present invention is of the following advantages:
For the grooves corresponding to the configuration of the pillars of the racks are provided, the pillars can be firmly surrounded by the grooves to tighten the plates. The grooves may also be arranged in serrate manner, and hence it enables distance adjustment between two lateral racks at any moment during assembly, and it is also allowed to add other support racks to the shelf to enhance its weight-carrying capability. Thus, it is possible to mount a wider shelf or to join several shelves together to improve its weight-carrying capability. Therefore, the structure of the present invention is simple, and it is allowed to adjust the width at any moment. It is also possible to add additional support racks to the shelf. Moreover, a plurality of shelves can be joined together. The carrying capability is enhanced accordingly. Furthermore, the shelf may be triangular sector-shaped; thus it can be assembled to be cylindrical or S-shaped by joining several triangular sector-shaped shelves together, which is more convenient and good-looking.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be further described in the following embodiments accompanying with the drawings.
Referring to FIGS. 1 to 16, a plate tensioning shelf comprises: two lateral racks 1 and several plates 2 mounted between the racks 1. A plurality of grooves 4 for engaging with the surface configuration of the pillars 3 of the racks 1 are provided on both sides of each of the plates 2 from corners thereof. The grooves 4 hold pillars 3 firmly and tighten the plates 2 firmly in the racks 1 when the plates 2 are mounted in the racks 1.
The pillar 3 of the rack 1 may be a cylindrical, rectangular, hexagonal, double-cylindrical, double-rectangular, double-rectangular and hollow, or double-hexagonal post. All of these configurations are within the scope of the invention. According to the intensity required, single or double pillars may be provided. The grooves 4 of the plates 2 is semi-circular, semi-square or semi-hexagonal. The number of the grooves 4 is arranged according to the use manner, at least one groove is arranged on each of the four corners, and at most the grooves are arranged on the entire frontal and back sides. Thus, it is allowed to set the distance between two lateral racks 1 flexibly, or add additional support racks between the two lateral racks, and it is also allowed to connect two or more shelves together by using the plates 2.
The configuration of the pillars and the arrangement of the grooves are not limited to the forms as described.
Referring to FIGS. 12 to 14, small crown-shaped protrusions 5 are provided in the grooves 4 of the plates 2, and recesses 6 corresponding to the protrusions 5 are provided on the pillars 3. The protrusion 5 is of a size adapted to be completely contained in the recess 6, and as a result, the plates 2 are self-locked and will not become loose easily.
Referring to FIGS. 15 to 16, the shelf of the present invention maybe triangular sector-shaped. It can be assembled into cylindrical or S-shaped shelf by joining several triangular sector-shaped shelves together, which is more convenient and good-looking.
Preferably, the plates are made of plastic. The plates with grooves are manufactured by one-step forming process. For the good elasticity, the plates can further facilitate the fastening and will not cause pillars surface damage. Meanwhile, the cost is also reduced.
Therefore, the structure of the present invention is simple. It is allowed to adjust the width at any moment and add support racks to racks to enhance the carry capability.
