Abstract

The utility model discloses an adjustable 180-degree blind hinge which comprises a hinge sliding board and a hinge rotary block. An arc guide rail groove is formed in the hinge sliding board through flangings at the upper side and the lower side of the hinge sliding board. A shaft hole is formed in the hinge rotary block. The hinge rotary block is assembled in the guide rail groove of the hinge sliding board through the arc face portion of the hinge rotary block. Balls are arranged between the upper side of the arc face portion of the hinge rotary block and the guide rail groove and between the lower side of the arc face portion of the hinge rotary block and the guide rail groove, so that the hinge rotary block is matched with the hinge sliding board in a sliding mode along the guide rail groove. A first strip-shaped hole is formed in the arc face portion of the hinge rotary block. The long axis of the first strip-shaped hole is parallel to the horizontal plane. A limiting pin is arranged on the hinge sliding board and inserted into the first strip-shaped hole so that sliding displacement of the hinge sliding board relative to the hinge rotary block can be limited. According to the adjustable 180-degree blind hinge, the hinge sliding board and the hinge rotary block can be prevented from falling and the purpose that a gap between a door leaf and a door frame is adjusted is achieved.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Adjustable 180 degree blind hinges as shown in Figure 1 and Figure 2, comprise hinge slide plate 6, hinge switch block 1, door leaf connecting plate 5 and hinge back shroud 2, described hinge slide plate 6 comprises arc surface part and the planar section of one, arc surface part and the planar section of hinge slide plate are tangent, the arc surface part of described hinge slide plate 6 is take the axis hole E of hinge switch block 1 as the center of circle, and hinge slide plate 6 forms the guide-track groove of one section of circular arc by the two side flanging K up and down of its arc surface part.Hinge switch block 1 is provided with axis hole E, the axis of this axis hole E is vertically Z-direction, be provided with ball groove G in the both sides up and down of the arc surface part of described hinge switch block 1, ball 3 is located in ball groove rotationally, hinge switch block 1 is assemblied in the guide-track groove of hinge slide plate 6 by its arc surface part, coordinate with the rolling of guide-track groove by ball, hinge switch block is coordinated with hinge slide plate slides along described guide-track groove.In the arc surface part of described hinge switch block, offer the first bar hole F, the major axis of the first bar hole is parallel with horizontal plane, hinge slide plate is provided with spacer pin 9, described spacer pin 9 is inserted in described the first bar hole F, spacer pin 9 moves in the first bar hole F, with the slide displacement of the relative hinge switch block of restriction hinge slide plate, effectively prevent hinge slide plate and the disengagement of hinge switch block, solve the potential safety hazard that door leaf drops.

The cross section of described door leaf connecting plate 5 is L-type, on a side of the planar section laminating of itself and hinge slide plate, offer two screwed hole A2, D2 and the second bar hole B1, another side offer four for the fixing counter sink H of door leaf, the axis direction of the axis hole of hinge switch block, i.e. Z-direction described in the long axis of described the second bar hole B1.On the planar section of described hinge slide plate, offer two Article 3 shape hole A1, D1s just right with the screwed hole difference of door leaf connecting plate, and the circular via hole B2 just right with the second bar hole, the major axis in described Article 3 shape hole and the major axis of the second bar hole are perpendicular, at door leaf during in closed condition, the long axis directions X of Article 3 shape hole A1, D1.Described hinge slide plate 6 is connected with door leaf connecting plate 5 with eccentric bolt 4 by two round end soket head cap screws 7, round end soket head cap screw 7 is connected with the screwed hole of door leaf connecting plate through the Article 3 shape hole of hinge slide plate, due to the long axis directions X in Article 3 shape hole, thus described round end soket head cap screw do not limit between hinge slide plate and door leaf connecting plate X to relative motion.Described eccentric bolt 4 comprises head and the screw rod of arranged off-centre, be provided with the flat mouth groove J of yi word pattern on the top of the screw rod of eccentric bolt, the screw rod of eccentric bolt is successively through the second bar hole B1 on door leaf connecting plate and the via hole B2 of hinge slide plate, fixing with nut 8, and the head that makes eccentric bolt 4 is positioned at the second bar hole, in the time reversing screw rod by flat mouth groove J, the described head with screw rod bias just forms similar cam principle, swing in the second bar hole B1 by it drive door leaf connecting plate 5 at X to movement.

For attractive in appearance and dustproof, described hinge back shroud 2 is inlaid between the flange of both sides up and down of hinge slide plate 6, internal construction is hidden, make the side arc surface part of hinge switch block 1 and door leaf connecting plate 5 and the laminating of hinge slide plate between hinge slide plate and hinge back shroud.

Referring to Fig. 3, above-mentioned blind hinge is in the time installing and using, and door leaf 12 is fixing by described counter sink and door leaf connecting plate 5, and the joint pin 13 in hinge seat 10 is through the axis hole E of described hinge switch block, described hinge switch block 1 can be rotated around joint pin 13, and described hinge seat 10 is fixing with doorframe 11.As shown in Figure 4, under the promotion of directed force F, open 140 while spending when door leaf 12, hinge switch block 1 interferes with doorframe 11, and hinge switch block 1 can not be rotated further again, and now hinge slide plate 6 not yet outwards slides.As shown in Figure 5, in the time that door leaf is rotated further, hinge slide plate 6 just outwards slides along the relative hinge switch block of described guide-track groove, and door leaf is opened through the segmented of rotation and slip, reaches door leaf and opens 180 objects of spending.

When need to regulate between door leaf 12 and doorframe 11 gap time, only need with flat mouth screwdriver by the flat mouth groove J on eccentric bolt 4, direction is on demand reversed this eccentric bolt, just can realize the movement of door leaf connecting plate 5 along directions X, thereby realized the object that regulates door leaf and doorframe gap, adjustment operation is very easy.
