12, it is inserted with latch 43 in this pin-and-hole one, and latch 43 through chute 1 and can slide, taxiing procedures in chute one
In, slide block slides equally in gap 1.It should be noted that the cross section of latch 43 is polygon, and latch and chute
Spacing between two surfaces of two arc surface contacts of adapts with the groove width of chute one, prevents latch in chute one
Rotate.
Further, one end of the folded box 2 20 of the present embodiment is provided with arc-shaped cavity and by extending to folded box in arc-shaped cavity
A pair arc linking arm 2 21 outside 2 20, the radius of this linking arm 2 21 adapts with the radius of chute 2 42, and a pair
Gap 2 23 between linking arm 2 21 adapts with the thickness of slide block 40.In the present embodiment, the end of linking arm 2 21 is provided with
Pin-and-hole 2 22, is inserted with latch 43 in this pin-and-hole two, and latch 43 through chute 2 42 and can slide in chute two, slides
During, slide block slides equally in gap 2 23.It should be noted that the cross section of latch is polygon, and latch and cunning
Spacing between two surfaces of two arc surface contacts of groove two adapts with the groove width of chute two, prevents latch at chute two
Interior rotation.
It should be noted that latch 43 center of circle of sliding trajectory between one 41 two extreme positions of chute in the present embodiment
Angle and the latch 43 central angle sum of sliding trajectory between 2 42 two extreme positions of chute is 180 °.As preferably, latch
43 between one 41 two extreme positions of chute the central angle of sliding trajectory be 120 °, latch 43 is in 2 42 two limit positions of chute
Between putting, the central angle of sliding trajectory is 60 °.Certainly, this simply a kind of preferred embodiment, the most of the present utility model uniquely
Limit.As long as meeting angle sum is 180 °, such as 110 °+70 °, 130 °+50 °, 100 °+80 °, the combinations such as 140 °+40 °
Mode.
In the present embodiment, one end that folded box 1 has arc-shaped cavity is provided with connection sheet 14, and this connection sheet 14 sets
There is screwed hole 15, and the axis of screwed hole 15 is positioned on the end face of folded box 1 and phase vertical with the axis of folded box 1
Hand over.Correspondingly, folded box 2 20 is provided with for accommodating the receiving chamber 25 connecting sheet 14.
Further, folded box one is additionally provided with the arcuate groove one 16 coaxial with screwed hole 15, correspondingly, in folded box
It is provided with the arcuate groove two identical with arcuate groove Radius at the bottom of two receiving chambeies, chamber.End face and the end face of folded box one in folded box two
Under fit-state, above-mentioned arcuate groove one constitutes cannelure with arcuate groove two.
Locking component 30 in the present embodiment, the barrel connector 32 including turncap 35, being located at turncap 35 one end, is located at rotation
The turncap lid 31 of the cap other end and the screw rod 33 being located in barrel connector, wherein screw rod 33 mates with screwed hole 15, tubular
The wall thickness of connector 32 adapts with the groove width of cannelure.Further, screw rod 33 being arranged with spring 34, screw rod 33 is near certainly
Being provided with pin-and-hole 33 by the position held, be inserted with spacer pin 36 in pin-and-hole, this spring is connecting between sheet and spacer pin.Bullet is set
The effect of spring is, when folder closes, spring provides tensile force, prevents turncap from loosening；Meanwhile, the process of turncap is being unscrewed
In, prevent turncap and folded box one disengaging.
As preferably, above-mentioned cannelure is cone tank, and the barrel of barrel connector adapts with cone tank.Tightening
During turncap, by contact of incline plane between taper barrel and cone tank, for the while of between folded box one and folded box two
Creating axial compressive force and radial pressure, the structural strength of folder is higher.
Folder of the present utility model, under closure state, one end of folded box one and folded box two is fixed by slide block, separately
One end is fixed by locking component, and wherein slide block is positioned at the receiving chamber that folded box one is formed with folded box two, and the space taken is little,
From appearance this slide block the most invisible, aesthetics promotes substantially, and the lifting surface area of slide block is relatively big, and folder is in the process of use
In structural strength higher.
In folding process, unclamp locking component so that latch slides respectively in chute one and chute two, and slides rail
The central angle of mark is 180 °, i.e. folded box one box folded against two rotates 180 °, owing to slide block plays linking folded box one and folds
The effect of box two, the stress of slide block more disperses, and service life is longer.
In a word, the foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all
Any amendment, equivalent and the improvement etc. made within spirit of the present utility model and principle, should be included in this practicality
Within novel protection domain.
