The specific embodiment
As shown in Figure 3, in the first embodiment of the present invention, folding carton comprises platform chassis 30, headwall 31 and the hinge means that connects platform chassis 30 and headwall 31.Hinge means is arranged on the end of platform chassis 30, the lower end of headwall 31, comprises outer hinge 34 and inner hinge 32.Its China and foreign countries' hinge 34 is fixedly installed on the platform chassis 30, and headwall 31 is pivotally attached on the outer hinge 34 by inner hinge 32, and inner hinge 32 is connected on the outer hinge 34 by bearing pin 35, can rotate around bearing pin 35, rotates thereby drive headwall 31, and realization folds and opens.End in bottom platform 10 is equipped with end balancing device.
As Fig. 3 and shown in Figure 5, end balancing device is connected between the platform chassis 30 and inner hinge 32 of folding carton, comprise the pull bar 33 of captiveing joint with inner hinge 32 and with pull bar 33 bonded assembly spring installations 36.Spring installation 36 comprises the Connection Block 37 of the two bottom sides that is arranged on platform chassis 30 and first slide bar 40 that is arranged in parallel and second slide bar 41.End at first slide bar 40 is fixed with slide 42; On second slide bar 41, an end opposite with first slide 42, be fixed with permanent seat 43.On slide 42 and permanent seat 43, be provided with the hole.The other end of first slide bar 40 passes the hole on the permanent seat 43, and is connected with pull bar 33; The other end of second slide bar 41 passes the hole on the slide 42, and is connected with Connection Block 37, thereby realizes the stationary positioned of permanent seat 43 with respect to platform chassis 30.Like this, when pulling first slide bar 40, but 43 motions of slide 42 relative fixed seats.Outside first, second slide bar 40 and 41, between slide 42 and the permanent seat 43, be arranged with elastic element, this elastic element can be a spring 45.
Shown in Fig. 3-6, when the headwall 31 of folding carton when open mode becomes folded state, headwall 31 rotates around bearing pin 35, inner hinge 32 drives pull bars 33 and rotates in the same way, and then pull bar 33 pullings first slide bar 40 is moved to the direction away from permanent seat 43.At this moment, slide 42, permanent seat 43 are close to each other, with spring 45 compressions.Because the elastic force of spring 45 is to the folding buffer action that plays of headwall 31.When the headwall 31 of folding carton is opened, pull bar 33 backward rotation, spring 45 extends under the effect of restoring force, and opening of headwall 31 played the power-assisted effect.
For spacing better, can between slide 42, permanent seat 43, set up auxiliary slide 44, on auxiliary slide 44, be provided with the hole of passing for first, second slide bar 40 and 41.Between slide 42 and the auxiliary slide 44 and between permanent seat 43 and the auxiliary slide 44 spring 45 is being set respectively.One of them slide bar, for example second slide bar 41 can be made of side by side two slide bars, and first slide bar 40 can be therein spacing with first slide bar 40 better between two slide bars.In this case, spring 45 can be arranged in the inner space of first slide bar 40 and second slide bar, 41 formations, and promptly spring 45 is set in outside first slide bar 40, in second slide bar 41.
As shown in Figure 7 and Figure 8, in the second embodiment of the present invention, the part identical with first embodiment is not repeated.This end balancing device comprise with the inner hinge 32 bonded assembly pull bars 33 of hinge means and with pull bar 33 bonded assembly spring installations 36.Pull bar 33 is hinged on the inner hinge 32 by bearing pin 51, can rotate around bearing pin 51.Spring installation 36 comprises that the permanent seat 56 that is arranged on platform chassis 30 two bottom sides, an end are by bearing pin 53 and pull bar 33 pivotally attached slide bars 54 and the slide 52 of captiveing joint with slide bar 54.Slide 52 is arranged near slide bar 54 and pull bar 33 bonded assembly ends, is used to prevent that spring 55 from deviating from; The other end of slide bar 54 is set in the permanent seat 56, can slide therein.Between slide 52 and permanent seat 56, be provided with spring 55.
When the headwall 31 of folding carton when open mode becomes folded state, headwall 31 rotates around bearing pin 35, pull bar 33 is around bearing pin 51 backward rotation, stretch out forward, promote slide bar 54 and slide towards permanent seat 56, this moment, spring 55 was compressed, because the elastic force of spring 55 is to the folding buffer action that plays of headwall 31.When the headwall 31 of folding carton was opened, pull bar 33 pulled back slide bar 54 away from permanent seat 56, and spring 55 extends under the effect of restoring force, further promoted bearing pin 53 and connecting rod 33 motions, and opening of headwall 31 played the power-assisted effect.
Though below only be that example is introduced with the headwall, the present invention also is applicable to the situation that corner post is folding and open.The end balancing device of folding carton of the present invention when end wall and/or corner post depart from the upright position, produces an application force, and this application force makes end wall and/or corner post that the trend of recovering the upright position be arranged; Thereby when platform chassis is folding, play buffer action at end wall and/or corner post, and will be manually power-assisted effect when base end wall and/or corner post are holded up.
