Specifically, as shown in Figure 1, the latent hinged flap 1 includes upper hinge 11 and lower jaw 12, the upper hinge 11 is under
Hinge 12 is respectively used to be fixed on the upper and lower ends of 2 inside the same side of doorframe, i.e., the fixed knot of described latent hinged flap 1 and doorframe 2
Structure is set to the inside of the doorframe 2, hides most of structure of the latent hinged flap 2, be only useful for connection door leaf (it is not shown,
Part similarly hereinafter) is exposed, to keep the appearance of the door using the latent hinged flap 1 more neat and artistic.
As shown in Fig. 2, the upper hinge 11 includes L shape corner brace, the L shape corner brace includes being mutually perpendicular to and for being fixedly arranged on
Upper joint face 111 and upper mounting surface 112 at 2 inner corner of doorframe, the upper mounting surface 112 open up mounting hole 1121,
The upper hinge 11 further includes bearing 113 in the mounting hole 1121, is arranged in the bearing 113 and vertically downward
Extend to be pierced by the first connecting shaft 114 of the doorframe 2 when in use, i.e., described first connecting shaft 114 can pass through the bearing
113 rotate relative to the upper mounting surface 112, and first connecting shaft 114 is for connecting door leaf.Since the L shape corner brace is used for
Corner inside the doorframe 2, the first connecting shaft 114 for being only useful for connection door leaf is exposed, realizes and hides upper hinge
Doorframe can be reinforced by the L shape corner brace while 11, reduce the accessory of doorframe 2, optimize cost.
The bearing 113 is micro metal bearing, can reduce the foreign matters such as dust, sundries and enter to the upper generation of hinge 11
Abrasion, while keeping the rotation of door leaf more light, smooth.
Preferably, at least one pin joint hole 1141, first connecting shaft 114 are offered in first connecting shaft 114
It can be circumferentially fixed by pin and the door leaf by the pin joint hole 1141 after being arranged in the door leaf.
Preferably, the mounting hole 1121 there are two being opened up on the upper mounting surface 112, for first connecting shaft
The different switch direction installation of 114 adaptation door leafs, makes hinge 11 on this that can be adapted to more installation situations, switchs in door leaf different
When no replacement is required different hinge.
As shown in figure 3, the lower jaw 12 includes orthogonal lower joint face 121 and lower mounting surface 122, the lower company
Junction 121 is used to be fixed on the inside of the doorframe 2, and the lower mounting surface 122 can be extended out the doorframe 2 when in use and set
In the bottom of the door leaf, the lower jaw 12 further includes the second connecting shaft 123 on the lower mounting surface 122.
Incorporated by reference to Fig. 3 and Fig. 4, the lower jaw 12 further includes needle bearing 124 and connecting column 125, the connecting column 125
It is fixed on the lower mounting surface 122, the needle bearing 124 and the second connecting shaft 123 are successively sheathed on the connecting column 123
On, i.e., described second connecting shaft 123 can be rotated by the needle bearing 124 relative to the connecting column 125.Further, institute
The bottom for stating the second connecting shaft 123 is equipped with the flange 1231 for abutting the needle bearing 124, when connecting door leaf by described convex
Edge 1231 increases the forced area of second connecting shaft 123, to realize better weight-bearing function, and due to the flange
1231 lower sections are provided that needle bearing 124, reduce the abrasion that the rotation of door leaf generates lower jaw 12, the needle bearing
124 compare plain bearing, just have very high load-carrying ability and intensity under lesser volume, can bear the weight of the door leaf.
