The beneficial effects of the utility model are: be hidden in door or the doorframe because upper hinge unit and following hinge component all are provided with, do not expose, can effectively prevent robber's destruction, do not influence the attractive in appearance of door, and of the present utility model simple in structure, use is reliable and the life-span is long, also is convenient to dismounting.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the sectional drawing after the utility model is installed;
Fig. 2 is a broken away view of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of concealed door hinge is made up of upper hinge unit 1 and following hinge component 2.Wherein upper hinge unit 1 comprises upper flap 11, upper hinge axle core bar 12 and upper bush 13, the top edge of door 3 is provided with mounting groove 31, upper flap 11 is provided with axis hole 111 and fixedlys connected with the top edge of door 3, upper bush 13 is fixedlyed connected with doorframe 4 top edges, upper hinge axle core bar 12 places in the mounting groove 31 and passes axis hole 111, extends in the upper bush 13.Wherein descend hinge component 2 to comprise lower flap 21, following hinge axis core bar 22 and doorframe lower supporting plate 23, doorframe lower supporting plate 23 is fixedlyed connected with doorframe 4 lower limbs, lower flap 21 also is provided with axis hole 211 and fixedlys connected with the lower limb of door 3, and following hinge axis core bar 22 passes axis hole 211 fixedlys connected with doorframe lower supporting plate 23.Because all being provided with, following hinge axis core bar 22, the doorframe lower supporting plate 23 of hinge axis core bar 12, upper bush 13 and the following hinge component 2 of upper hinge unit 1 be hidden in door 3 or the doorframe 4, do not expose, can effectively prevent robber's destruction, and not influence the attractive in appearance of door.
For the ease of the installation and removal between door 3 and the doorframe 4, upper hinge unit 1 also includes " L " type location-plate 14, it plays an end fixedlys connected with upper flap 11, there is spring 15 to withstand between upper hinge axle core bar 12 and location-plate 14 lower surfaces, upper hinge axle core bar 12 sides also are provided with screw 121, have screw rod 122 to be connected with screw 121, be provided with gathering sill 32 at the edge of door 3 close hinges accordingly, screw rod 122 extends gathering sill 32.When installing so earlier the upper bush 13 of the doorframe lower supporting plate 23 of hinge component 2 down, upper hinge unit 1 in the fixed installation of the relevant position of doorframe 4, after then upper flap 11, upper hinge axle core bar 12, location-plate 14 and spring 15 being assembled, the miscellaneous part of this assembly being removed upper flap 11 places in the mounting groove 31 of door, and upper flap 11 places in the groove 33, and upper flap 11 is provided with and the door 3 fixing through holes 16 of usefulness, has screw 17 to pass through hole 16 and upper flap 11 is fixedlyed connected with 3 gets final product.And lower flap 21 is also fixedlyed connected with door 3 by same mode, and hinge axis core bar 22 is also fixedlyed connected with doorframe lower supporting plate 23 down.Then the axis hole 211 with lower flap 21 passes down the bottom elder generation and doorframe 4 assemblings of hinge axis core bar 22 with door 3, then with pulling moving screw rod 122, upper hinge axle core bar 12 compression springs 15, what make that original upper hinge axle core bar 12 stretches out upper flap 11 parts is withdrawn into upper flap below 11, this moment, the top with door 3 pushed relevant position in the doorframe 4, and release screw rod 122, upper hinge axle core bar 12 stretches in the upper bush 13 under the effect of spring 15 can finish assembling, and door 3 can rotate around person's upper hinge axle core bar 12 and following hinge axis core bar 22.Optimal way as such scheme, upper hinge axle core bar 12 lower ends are provided with the shaft shoulder 123, location-plate 14 lower surfaces also are provided with through hole 141, upper hinge axle core bar 12 shaft shoulders 123 extend through through hole 141 with the lower part, on the spring 15 socket upper hinge axle core bars 12 and withstand between the shaft shoulder 123 and location-plate 14 lower surfaces of upper hinge axle core bar 12.Wherein through hole 141 plays the effect of guiding, its axis hole 111 with upper flap 11 is coaxial, guarantee moving both vertically of upper hinge axle core bar 12, also reduced because the gap that exists between upper hinge axle core bar 12 and the axis hole 111 causes issuable the rocking between door 3 and the doorframe 4.
Following hinge axis core bar 22 is made up of screw rod 221 and lower sleeve 222, the doorframe lower supporting plate 23 corresponding screws 231 that are provided with, and screw rod 221 passes lower sleeve 222 and is connected with screw 231.It also is to be convenient to the installation and removal of hinge component 2 down that following hinge axis core bar 22 adopts this form of screw rod, and lower sleeve 222 is in order to protect screw flight not to be worn.
For the flexibility that increases the hinge activity, the wearing and tearing that reduce parts, the inner surface of upper bush 13 is provided with rolling bearing 131, and following hinge component 2 also is provided with thrust ball bearing 24 and is socketed in down on the hinge axis core bar 22 and between lower flap 21 and doorframe lower supporting plate 23.Significantly reduced the frictional force of the part that produces relative rotation like this, rotated more flexibly, door 3 switching is also more laborsaving, also reduced simultaneously rotating part wearing and tearing, increase the service life.
