In this embodiment, the hinge body 1 is a detachable connection structure on the base 2, wherein the base 2 is used for being connected and fixed with a side plate of the cabinet body, and the hinge body 1 is used for being hinged with an accessory connected to the cabinet door.
In this embodiment, base 2 includes top cap 21, regulating plate 22, fixing base 23 and regulating part 24, regulating plate 22 connects on fixing base 23 along horizontal direction slidable, top cap 21 is connected with hinge body 1 and connects on fixing base 23 along vertical direction slidable, regulating part 24 is used for ordering about regulating plate 22 along horizontal direction reciprocating motion, it is equipped with initiative screens and driven screens to correspond respectively on regulating plate 22 and the top cap 21, the mutual butt of initiative screens and driven screens is used for ordering about top cap 21 elevating movement when regulating plate 22 moves along the horizontal direction.
Through such setting, regulating plate 22 can be ordered about by regulating part 24 along horizontal direction reciprocating motion, regulating plate 22 links top cap 21 elevating movement through the cooperation structure of initiative screens and driven screens, at the in-process of regulation, the effect of support has been played to top cap 21 to the initiative screens on the regulating plate 22, and at the in-process of regulation, initiative screens and driven remain the contact all the time, the atress is even, the uneven condition of eccentric atress can not appear, the stability and the accuracy nature of hinge altitude mixture control have been promoted.
In this embodiment, the back side of the top cover 21 is a concave structure, the adjusting plate 22 is embedded in the back side of the top cover 21, the fixing seat 23 is connected to one side of the adjusting plate 22 away from the top cover 21, and the adjusting plate 22 is clamped between the top cover 21 and the fixing seat 23. The fixed seat 23 is used for being attached to, connected with and fixed to a side plate of the cabinet body.
Through such structural design, make regulating plate 22, top cap 21 and the connection of fixing base 23 three inseparabler, reduce the space that occupies, make the hinge more miniaturized, reduce cost of transportation. In addition, the tight assembling structure is also beneficial to improving the stability of the adjusting plate 22 and the top cover 21 during sliding adjustment, and the safety of the product is improved.
Furthermore, an inclined guide surface is arranged on one side of at least one of the driving clamping position and the driven clamping position, which is abutted against each other. In this embodiment, the surfaces of the driving detent and the driven detent, which abut against each other, are inclined guide surfaces, and the guide surfaces of the driving detent and the driven detent are attached to each other. In other embodiments, inclined guide surfaces can also be provided only on the master or slave detent. In this embodiment, all set up the spigot surface of slope through on initiative screens and driven screens, the spigot surface butt each other of initiative screens and driven screens makes the contact of initiative screens and driven screens inseparabler, and is more stable when regulating plate 22 promotes top cap 21 and goes up and down, and regulating plate 22 also can provide supporting role for top cap 21 better.
Further, initiative screens is located including corresponding last initiative screens 221 and the lower initiative screens 222 of the upside and the downside of regulating plate 22, driven screens is located including corresponding last driven screens 231 and the lower driven screens 232 of the upside and the downside of top cap 21, go up initiative screens 221 and lower initiative screens 222 and correspond ground and last driven screens 231 and the lower driven screens 232 on opposite side butt respectively.
