The specific embodiment
A kind of preferred embodiment that provides according to the utility model, referring to Fig. 2 and Fig. 6, it comprises a loam cake 1, a lower cover 2 and an attaching parts 3 that described loam cake 1 and described lower cover 2 is hinged.The utility model difference with the prior art is that referring to Fig. 3, Fig. 8 and Fig. 9, the rear end 11,21 of described loam cake 1 and described lower cover 2 bends inwards and forms a curved portions 12,22, and the outside face of described curved portions 12,22 is formed with tooth 13,23.The outside face of described curved portions 12,22 is meant the end face of described curved portions 12,22 bending back extendible portions in described loam cake 1 and described lower cover 2, the i.e. part that can see.Described loam cake 1 of the present utility model and described lower cover 2 are symmetrical structures.Referring to Fig. 4, Fig. 7 and Figure 11, described attaching parts 3 in the utility model is the U type, it can snap together the curved portions 12,22 of the rear end 11,21 of described loam cake 1 and described lower cover 2 and be hinged with the rear end 11,21 of described loam cake 1 and described lower cover 2 respectively, forms a built-in Double pin hinge structure thus.Hinged between described attaching parts 3 and described loam cake 1 and the described lower cover 2 is by following structure reality: referring to Fig. 3, Fig. 5, Fig. 8 and Fig. 9, the front end 121,221 of the curved portions 12,22 of described loam cake 1 and described lower cover 2 forms pin-and-hole 14,24 to its center of circle extension and at its circle centre position, described pin-and-hole 14,24 and described curved portions 12,22 concentrics, said structure can guarantee that described curved portions 12,22 moves in a circle along pin-and-hole 14,24.Referring to Fig. 7, the dual- side 32,33 of described attaching parts 3 extends internally and respectively is formed with pin-and-hole 321,331, after described attaching parts 3 is fastened on the described curved portions 12,22, described pin-and-hole 321 can with described pin-and-hole 24 on same axis.Described pin-and-hole 331 and described pin-and-hole 14 realize that described attaching parts 3 and described loam cake 1 and described lower cover 2 are hinged thereby two straight pins 4 pass described pin-and-hole 14,24,321,331 on same axis.Said structure, wherein a straight pin 4 passes described pin-and-hole 321 and rotating shaft of described pin-and-hole 24 formation, and another root straight pin 4 passes described pin-and-hole 331 and described pin-and-hole 14 forms another rotating shafts.Therefore, the curved portions 22 of described lower cover 2 can be rotated around article one rotating shaft, and the curved portions 12 of described loam cake 1 can be rotated around the second rotating shaft, finally realizes built-in Double pin hinge structure.
Realize that in order to make the utility model the synchronous bidirectional of described loam cake 1 and described lower cover 2 rotates, referring to Fig. 7 and Figure 11, the utility model is equipped with a pair of gear 31 that is meshing with each other together in the inside of described attaching parts 3, described gear 31 is meshed with tooth 13,23 on the curved portions 12,22 of described loam cake 1 and described lower cover 2 simultaneously.Therefore, when described loam cake 1 moved, described curved portions 12 drove a pair of described gear 31 relative motions by the tooth on it 13, thereby drove curved portions 22 motions of described lower cover 2, realized that synchronous bidirectional moves.Because the motion of the synchronous bidirectional of described loam cake 1 and described lower cover 2 makes described loam cake 1 and described lower cover 2 can respectively open 90 degree simultaneously, thereby makes both open 180 degree relatively.Owing to adopt the gear mesh structure, can make the folding of packing box steadily convenient.Simultaneously, described loam cake 1 can be stopped on any angle convenient the use with respect to described lower cover 2.
Referring to Fig. 4 and Fig. 5, in a kind of preferred embodiment that the utility model provides, described curved portions 12 forms in the both sides 111,112 of the rear end 11 of described loam cake 1; Described curved portions 22 forms in the both sides 211,212 of the rear end 21 of described lower cover 2, and described gear 31 is two pairs, and it is installed in the two ends of described attaching parts 3 and corresponding with the position of described curved portions 12,22 respectively.Because described curved portions 12,22 is arranged on both sides, therefore, dual- side 32,33 middle parts of described attaching parts 3 extend internally and form described pin-and-hole 321,331.Thereby make pin-and-hole 321 can with the pin-and-hole 24 of described curved portions 22 front ends on same axis; The pin-and-hole 14 of described pin-and-hole 331 and described curved portions 12 front ends is on same axis.Described gear 31 and described curved portions 12,22 are arranged on both sides, can make packing box stressed evenly, be unlikely to distortion during unlatching, the convenient unlatching.
Described curved portions 12,22 in the utility model also can form in the middle part of the rear end 11,21 of described loam cake 1 and described lower cover 2, this moment, described gear 31 was a pair of, and it is installed in the middle part of described attaching parts 3 and corresponding with the position of described curved portions 12,22.And this moment, the side 32,33 at the two ends of described attaching parts 3 extends internally and forms described pin-and-hole 321,331.
Can be released by above embodiment, described curved portions 12,22 can form in the middle part and the both sides of the rear end 11,12 of described loam cake 1 and described lower cover 2 simultaneously, and this moment, logarithm and the position of described gear 31 were corresponding with described curved portions 12,22.Pin-and-hole 321,331 positions of described attaching parts 3 also adapt with described curved portions 12,22, and promptly described pin-and-hole 321,331 is close proximity to the side of described curved portions 12,22.
Referring to Fig. 6, the front end 15,25 of described loam cake 1 of the present utility model and described lower cover 2 is equipped with interface arrangment 5.Described interface arrangment 5 can make described loam cake 1 and described lower cover 2 be fastened togather.
Referring to Fig. 3, in the foregoing description that the utility model provides, described curved portions 12, the 22 pairing center of circle angle a of described loam cake 1 and described lower cover 2 are the 145-165 degree.The curved portions 12,22 of above-mentioned angle can make the part of described gear 31 existing enough motions, can guarantee that again described attaching parts 3 can have enough big space motion.
Referring to Fig. 3, the total length 2L1 of the described gear 31 in the foregoing description that the utility model provides is 30% of described attaching parts 3 total length L.The total length of said here described gear 31 is meant the total length that every pair of gear 31 is added up, and as adopting two pairs of gears 31 in the present embodiment, therefore, its total length is the length sum of two pairs of gears, i.e. L1+L1.Overall width W1 after a pair of described gear 31 engagements is 35% of described attaching parts 3 overall width W.The aforementioned proportion relation can guarantee that the described attaching parts 3 and the matching relationship of described loam cake 1 and described lower cover 2 reach optimization.Simultaneously, both guaranteed that described gear 31 had enough fitting surfaces with described curved portions 12,22, can guarantee again has enough shaping positions for the pin-and-hole on the described attaching parts 3 321,331.
