Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of classroom stainless steel rack unit includes left corrosion resistant plate, right corrosion resistant plate, upper corrosion resistant plate and lower corrosion resistant plate.Left corrosion resistant plate, right corrosion resistant plate, upper corrosion resistant plate are identical with lower corrosion resistant plate size, and left corrosion resistant plate, right corrosion resistant plate, upper corrosion resistant plate and lower corrosion resistant plate surround rectangle frame jointly.Corrosion resistant plate is used to allow for its feature easy to clean, that non-corrosive, intensity are high.
Left corrosion resistant plate upper edge and upper corrosion resistant plate left margin all fall 45 degree of angles so that left corrosion resistant plate upper edge and upper corrosion resistant plate left margin can be good at involutory.
Left corrosion resistant plate and upper corrosion resistant plate intersection arrange stainless interconnecting piece and stainless outer connector, and interconnecting piece is positioned on the right side of left corrosion resistant plate and on the downside of upper corrosion resistant plate, and outer connector is positioned on the left of left corrosion resistant plate and on the upside of upper corrosion resistant plate.
On the right of upper corrosion resistant plate edge and right corrosion resistant plate upper edge all fall 45 degree of angles so that on the right of upper corrosion resistant plate edge and right corrosion resistant plate upper edge can be good at involutory.
Upper corrosion resistant plate and right corrosion resistant plate intersection arrange stainless interconnecting piece and stainless outer connector, and interconnecting piece is positioned on the left of right corrosion resistant plate and on the downside of upper corrosion resistant plate, and outer connector is positioned on the right side of right corrosion resistant plate and on the upside of upper corrosion resistant plate.
On the right of lower corrosion resistant plate edge and right corrosion resistant plate lower edge all fall 45 degree of angles so that on the right of lower corrosion resistant plate edge and right corrosion resistant plate lower edge can be good at involutory.
Lower corrosion resistant plate and right corrosion resistant plate intersection arrange stainless interconnecting piece and stainless outer connector, and interconnecting piece is positioned on the left of right corrosion resistant plate and on the upside of lower corrosion resistant plate, and outer connector is positioned on the right side of right corrosion resistant plate and on the downside of lower corrosion resistant plate.
45 degree of angles are all fallen so that lower corrosion resistant plate left margin and left corrosion resistant plate lower edge can be good at involutory in lower corrosion resistant plate left margin and left corrosion resistant plate lower edge.
Lower corrosion resistant plate and left corrosion resistant plate intersection arrange stainless interconnecting piece and stainless outer connector, and interconnecting piece is positioned on the right side of left corrosion resistant plate and on the upside of lower corrosion resistant plate, and outer connector is positioned on the left of left corrosion resistant plate and on the downside of lower corrosion resistant plate.
Corrosion resistant plate is between interconnecting piece and outer connector, and interconnecting piece and outer connector form good clamping effect to corrosion resistant plate.
Interconnecting piece 3 and outer connector 1 all extend in the equal fore-and-aft direction of angle bar shape, interconnecting piece and outer connector, the length of interconnecting piece and outer connector all equivalently-sized with corrosion resistant plate fore-and-aft direction.Interconnecting piece and outer connector are constituted by two blocks of webs, and each interconnecting piece and outer connector are respectively provided with two row through holes, and this two row through hole lays respectively on two webs.The through hole that each column through hole is equidistantly arranged by several fore-and-aft directions is constituted, and through hole 4 also extends through the corrosion resistant plate between interconnecting piece and outer connector.
Through hole be disposed to realize the installation of locking mechanism.
Interconnecting piece, corrosion resistant plate 2 and outer connector are linked together by locking mechanism, and locking mechanism includes the first half locking pieces 5 and the second half locking pieces 6.
The first half locking pieces include hemispherical Shell I 7 and guide cylinder 9, the axis of guide cylinder overlaps with the centre of gyration line of hemispherical Shell I, the inner of guide cylinder is connected on hemispherical Shell I inwall, and the outer end of guide cylinder is stretched out from the opening of hemispherical Shell I, and the inwall of guide cylinder has annular groove 12.
The second half locking pieces include hemispherical Shell II 8 and guide pillar 10, guide pillar is cylindric, the axis of guide pillar overlaps with the centre of gyration line of hemispherical Shell II, the inner of guide pillar is connected on the inwall of hemispherical Shell II, the outer end of guide pillar is stretched out from the opening of hemispherical Shell II, the outer end of guide pillar is provided with elastic lock claw 11, makes elastic lock claw enter annular groove inner guiding post and guide cylinder axial lock in guide pillar gos deep into guide cylinder.
Guide cylinder is arranged in through hole, the external diameter of guide cylinder is identical with through-hole aperture, when guide pillar and guide cylinder axial lock, axial distance between the first half locking piece hemispherical Shells I and the second half locking piece hemispherical Shells II is equal to interconnecting piece thickness, corrosion resistant plate thickness and outer connector thickness sum, and it is firm that outer connector, corrosion resistant plate and interconnecting piece are connected by the first half locking pieces and the second half locking piece lockings.
The thickness of left corrosion resistant plate, right corrosion resistant plate, upper corrosion resistant plate, lower corrosion resistant plate, interconnecting piece and outer connector is 3-5mm.
Preferably, the quantity of each column through hole is 5-7.
Owing to interconnecting piece stress is relatively big, therefore it is provided with triangle between the two of interconnecting piece blocks of webs and strengthens connection rib, improve its intensity.
