Abstract

The utility model discloses a hidden hinge of closing certainly, including hinge box body and L type linking arm, L type linking arm is equipped with two, and L type linking arm symmetry sets up to concatenate the round pin axle in the centre of L type linking arm, the inner wall symmetry of hinge box body is equipped with the spout, and the spout top is equipped with the screw socket, and the screw socket takes the foot screw in the screw socket, take the lower extreme of foot screw to cup joint the spring, the short-end of L type linking arm passes through the axostylus axostyle and rotates to be connected in the hinge box body, and the long end of L type linking arm passes through the axostylus. This hidden self-closing hinge promotes the long end axostylus axostyle of L type linking arm through the effect of spring, alright make this hinge motion realize self-closing's function, and very convenient and practical, the screw of taking the foot that sets up moreover can adjust the dynamics of closing.

Description

Hidden self-closing hinge

Technical Field

The utility model belongs to the technical field of the hinge, concretely relates to hidden self-closing hinge.

Background

The door, window and wing are connected with the corresponding frame body through hinges to realize the opening and closing functions, the common hinge is composed of two blades and a pin shaft thereof, one blade is fixed on the side surface of the door or window body, the other blade is fixed on the side surface of the corresponding frame body, the door and the window can rotate around the pin shaft, the hinges with the structure are exposed, not only occupy space, but also influence the flatness and the attractiveness, the existing hinge with the invisible function has unsatisfactory invisible effect and is not suitable for plates with thinner sizes.

Application number CN 201820950916.7's a two stealthy door hinges of biax two divisions, two hinge seats including the symmetry setting, it has long pinhole to open on the same straight line in the inboard of hinge seat, the inboard in long pinhole is equipped with the short round pin spout, the one end of long pinhole through long pin connection hinge arm, the middle part of two hinge arms is passed through the hinge arm connecting pin and is connected, the other end of hinge arm passes through short round pin sliding connection pin spout, still cup jointed the short round pin amortization spring on the short round pin. The double-shaft double-opening invisible door hinge adopts a connecting structure of the double-cross double-connecting shaft and the double-cross double-connecting arm, reduces the installation height, and achieves miniaturization and universalization; this stealthy hinge scheme makes the installation thickness of product reduce through optimizing size and structure for most doors need not break the wall body in the installation, and the noise that the short pin produced when the motion can be reduced in the setting of short pin amortization reed.

But the double-shaft double-opening invisible door hinge does not have the function of self-closing and is less practical in the situation that some doors and windows are opened and need to be self-closed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a hidden self-closing hinge to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a hidden hinge of closing certainly, includes hinge box body and L type linking arm, L type linking arm is equipped with two, and L type linking arm symmetry sets up to concatenate the round pin axle in the centre of L type linking arm, the inner wall symmetry of hinge box body is equipped with the spout, and the spout top is equipped with the screw socket, and the screw socket takes the foot screw in the screw socket, take the lower extreme of foot screw to cup joint the spring, the short end of L type linking arm passes through the axostylus axostyle rotation and connects in the hinge box body, and the long end of L type linking arm passes through the axostyl.

Preferably, a gasket is arranged in the middle of the pin shaft.

Preferably, the middle position of the upper end of the hinge box body is clamped with a decorative cover.

The utility model discloses a technological effect and advantage: this hidden self-closing hinge promotes the long end axostylus axostyle of L type linking arm through the effect of spring, alright make this hinge motion realize self-closing's function, and very convenient and practical, the screw of taking the foot that sets up moreover can adjust the dynamics of closing.
