Description

Plastic box

1, technical field: plastic box of the present utility model belongs to field of containers.

2, background technology: it is commonly used to Turnover Box to transport fruit, has following defective after common Turnover Box is stacked together: 1, not withstand voltage, easily damage the fruit 2 deposited in it, built on the sand by pressure, and collapse 3 easily, fanning effect is poor, is unfavorable for the preservation of fruit.

3, summary of the invention: the purpose of this utility model is to propose a kind of being fit to and stacks, and breezy plastic box.

The purpose of this utility model is achieved in that plastic box integral body is the uncovered cavity cuboid in upper surface, surrounding, tank wall upper end outwards is turned into crimping, all have draw-in groove on each crimping near four jiaos of tops, have hole clipping on the groove bottom, draw-in groove outer rim on two relative long paper limits or two short crimpings, active linking to each other of a square edge by the connecting strap and the load-bearing seat of a right angle triangle body shape respectively, another square edge of load-bearing seat also connects connecting strap is housed, and two connecting straps all have groove towards the end at place, top, angle, right angle; The hole clipping corresponding position is equiped with fixture block on two connecting straps and crimping.At the back side of load-bearing seat installing positioning convex strip.Be waveform at the bottom of the case, have inwardly recessed positioning groove at Qi Sijiao and positioning convex strip corresponding position, box plate is equal hollow out except that four jiaos.Be equiped with vertical pillar stiffener on the wall at tank wall four interior angle knuckle places and two square edge places, its upper surface is lower than the crimping upper surface.Have air grid around the tank wall, have handle aperture at long tank wall or short tank wall middle and upper part.

The right-angled triangle at four jiaos of places of upset of load-bearing seat and casing is fastened fully, and under the together support of casing crimping and pillar stiffener, Turnover Box just can stack by many casees; Because the positioning groove of case bottom, upper strata is stuck by the positioning convex strip at place, lower floor case angle, many casees stack just relatively more firm, are difficult for collapsing; Be the waveform of hollow out at the bottom of each case case in addition,, be beneficial to the preservation of fruit so this case fanning effect is good.

4, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples

Fig. 1 is the plastic box structural representation

Fig. 2 is the connection structure scheme drawing of tank wall and load-bearing seat

Fig. 3 is the structural representation of one jiao of the case bottom of upset

Fig. 4 is a load-bearing holder structure scheme drawing

5, the specific embodiment:

1, at the bottom of load-bearing seat 2, handle aperture 3, pillar stiffener 4, the case 5, tank wall 6, air grid 7, positioning groove 8, crimping 9, draw-in groove 10, hole clipping 11, fixture block 12, connecting strap 13, base 14, groove 15, positioning convex strip legend:

Embodiment 1: shown in Fig. 1-4, plastic box integral body is the uncovered cavity cuboid in upper surface, surrounding, tank wall 5 upper end outwards is turned into crimping 8, all have draw-in groove 9 on each crimping 8 near four jiaos of tops, have hole clipping 10 on the groove bottom, draw-in groove 9 outer rims on two relative long paper limits 8 or two short crimpings 8, respectively pass through active the linking to each other of a square edge of the connecting strap 12 and the load-bearing seat 1 of a right angle triangle body shape, another square edge of load-bearing seat 1 also connects connecting strap 12 is housed, two connecting straps 12 all have groove 14 towards the end at place, top, angle, right angle, and this groove slightly is wider than crimping 8 width; Hole clipping 10 corresponding positions are equiped with fixture block 11 on two connecting straps 12 and crimping 8.Be equiped with the positioning convex strip parallel 15 at the back side of load-bearing seat 1 with hypotenuse.4 is waveform at the bottom of the case, has inwardly recessed positioning groove 7 at Qi Sijiao and positioning convex strip 15 corresponding positions, 4 plates equal hollow out except that four jiaos at the bottom of the case.Be equiped with vertical pillar stiffener 3 on the wall at tank wall 5 four interior angle knuckle places and two square edge places, its upper surface is lower than crimping 8 upper surfaces.Have air grid 6 around the tank wall 5, have handle aperture 2 at long tank wall 5 or short tank wall 5 middle and upper parts.

When in case, putting into fruit, upwards spur load-bearing seat 1, fixture block 11 and hole clipping 10 are broken away from, load-bearing seat 1 resets load-bearing seat 1 after the fruit of packing into to the upset of the case outside.When the casing multilayer stacked, the positioning groove 7 that the positioning convex strip 15 at place, lower floor case angle is snapped in case bottom, upper strata got final product.

Claims

1, a kind of plastic box, integral body is the uncovered cavity cuboid in upper surface, it is characterized in that: the crimping of surrounding, tank wall upper end for outwards overturning, all have draw-in groove on each crimping near four jiaos of tops, have hole clipping on the groove bottom, draw-in groove outer rim on two relative long paper limits or two short crimpings, active linking to each other of a square edge by the connecting strap and the load-bearing seat of a right angle triangle body shape respectively, another square edge of load-bearing seat also connects connecting strap is housed, and two connecting straps all have groove towards the end at place, top, angle, right angle; The hole clipping corresponding position is equiped with fixture block on two connecting straps and crimping, at the back side of load-bearing seat installing positioning convex strip, it at the bottom of the case waveform, have inwardly recessed positioning groove at Qi Sijiao and positioning convex strip corresponding position, box plate is equal hollow out except that four jiaos, is equiped with vertical pillar stiffener on the wall at tank wall four interior angle knuckle places and two square edge places, and its upper surface is lower than the crimping upper surface, have air grid around the tank wall, have handle aperture at long tank wall or short tank wall middle and upper part.
