Description

Concealed adjustable hinge

Technical Field

The utility model relates to a hinge, in particular to a hidden adjustable hinge.

Background

The existing hidden hinge comprises a leaf and a leaf seat, wherein one end of the leaf is provided with a shaft sleeve and is hinged on the leaf seat through a hinged shaft, the leaf seat is fixed in a door frame, the leaf is fixed with a door leaf, and the hidden hinge is more attractive compared with the existing visible hinge, but the existing hidden hinge can not adjust the height of the door leaf generally, so that the hidden hinge capable of adjusting the height of the door leaf is very troublesome to adjust if a height interval exists between the door leaf and the door frame during installation, and therefore, the hidden hinge capable of adjusting the height of the door leaf is urgently needed in the market; of course, if the hinge can only be adjusted in height, the problem of troublesome adjustment of the installed door leaf and the door frame occurs if a left gap and a right gap occur, and therefore the gap between the door leaf and the door frame can be adjusted by the hidden hinge.

SUMMERY OF THE UTILITY MODEL

In view of the current defect that hidden hinge exists, the utility model aims to solve the technical problem be: the hidden adjustable hinge can adjust the height of the door leaf; simultaneously should hide adjustable hinge and still need to possess and to adjust the clearance ability between door leaf and the door frame.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: a concealed adjustable hinge comprising:

the hinge is C-shaped, one side of the hinge extends to form an insertion part, a row of bolt through holes are vertically formed in the insertion part, and a hinge shaft is fixed on the other side of the hinge;

the hinge shaft can rotate around the insertion point on the vane seat;

the seat core is provided with an inserting groove on one vertical side, the inserting groove is used for clamping the inserting part, and the upper end and the lower end of the seat core are threaded heads;

an adjusting seat, wherein one side of the adjusting seat is provided with a clamping opening, the upper end and the lower end of the inner side of the clamping opening are provided with inner screw holes, the inserting part is inserted in the clamping opening, the thread heads at the upper end and the lower end of the seat core are in threaded connection with the inner screw holes of the clamping opening, meanwhile, the adjusting seat is also provided with bolt fixing holes opposite to the bolt through holes, and fixing bolts pass through the bolt fixing holes at the two sides of the clamping opening and the bolt through holes on the inserting part in the clamping opening to fix the two,

the diameter of the fixing bolt is smaller than that of the bolt through hole.

This hide adjustable hinge makes the thread head can extrude the seat core through the thread head at both ends about the roating seat core, because the page or leaf seat is the snap-on in the door frame, the page or leaf is fixed with the page or leaf seat again, like this when the thread head extrudees behind the seat core under the unable circumstances that removes of page or leaf again, adjust the seat and will drive fixing bolt and reciprocate along the bolt through-hole, the messenger fixes the door leaf height on adjusting the seat and can adjust, its altitude mixture control's volume is greater than fixing bolt diameter size by bolt through-hole diameter and decides.

Furthermore, the heights of the two ends of the inserting part are lower than the height of the leaf. The above design facilitates the fixation of the insertion part.

Furthermore, the outer side of the hinged shaft is sleeved with a shaft sleeve, and the shaft sleeve is fixed with two ends of the leaf seat. The above design facilitates the rotation of the sheet.

Furthermore, the upper side and the lower side of the insertion groove of the seat core extend outwards to form a clamping block, a fastening opening is formed between the clamping block and the insertion groove, and the upper end and the lower end of a seal strip are clamped in the fastening opening to seal the insertion groove, so that the insertion part is prevented from being separated from the seat core.

Furthermore, the hidden adjustable hinge also comprises an eccentric device, the eccentric device consists of eccentric holes arranged on the insertion part and the seat core and an eccentric shaft used for fixing the eccentric holes of the insertion part and the seat core, and meanwhile, wrench through holes are also arranged on the seal and the adjusting seat. The design is that when a gap exists between the door leaf and the door frame, the fixing bolt on the clamping piece of the adjusting seat is slightly loosened, then the inner hexagonal wrench penetrates through the wrench through hole, the inner hexagonal hole of the eccentric shaft is inserted to enable the eccentric shaft to rotate, the eccentric shaft rotates to enable the seat core to move towards the door frame or the door leaf along the leaf inserting part, and the seat core pushes the adjusting seat to move, so that the door leaf fixed on the adjusting seat moves.

Further, the diameter of the inner threaded hole is larger than the width of the clamping opening. The design structure is reasonable, and the clamping and inserting part of the adjusting seat is convenient to adjust.

Compared with the prior art, the utility model has the advantages of: hide adjustable hinge can adjust the height between door leaf and the door frame, can adjust the interval between door leaf and the door frame again, when the installation error appears, adjust very convenience like this.
