The solution to the problem

The beneficial effects of the invention

Beneficial effect

Through the structural design of the hinge, the first body and the second body are rotated to the limit state of folding and close due to the arrangement of the hinge group. Because the hinge group itself has a certain size, the first body and the second body The two main bodies will not abut on one end close to the hinge assembly, which enables the first main body to rotate relative to the second main body until the first plate body and the second plate body are relatively parallel, and rotate to the first plate body and the second plate body When the included angle is 0°, the first body and the second body can be folded and brought together to a greater extent.

When the hinge of the present invention is installed in the shower door assembly, when the shower door assembly is in the open state, the first door panel and the second door panel can be better folded and condensed, avoiding the excessively large angle between the first door panel and the second door panel It occupies a large amount of external space to avoid affecting the use of users, and is beneficial to the simple structure of the shower door assembly.

The first cavity and the second cavity are provided, the hinge group and the first body are hinged in the first cavity, and the hinge group and the second body are hinged in the second cavity, which is beneficial to the simple structure of the hinge.

When the first hinge is inserted into the first cavity to be hinged with the first body, if the first hinge is set as a straight bar, and the second hinge is set as a straight bar, the first body is opposite When the second body rotates to the folded state, the first hinge and the cavity wall of the first cavity, the first hinge and the cavity wall of the second cavity, the second hinge and the cavity wall of the first cavity And the second hinge may abut against the cavity wall of the second cavity. Therefore, the first hinge is set to include a first bending section, a second bending section and a first connecting section, and the first bending Section, the second bending section and the first connecting section form a "C"-shaped structure; and the second hinge is set to include a third bending section, a fourth bending section and a second connecting section, and the third bending section Section, the fourth bending section and the second connecting section form a "C"-shaped structure; in this way, the cavity between the first hinge and the first cavity can be avoided when the first body rotates relative to the second body to the folded state. The wall, the first hinge and the cavity wall of the second cavity, the second hinge and the cavity wall of the first cavity, and the second hinge and the cavity wall of the second cavity are in abutment phenomenon, which is beneficial to make the first The board body and the second board body are smoothly folded and close to the state where the included angle is 0°.

The contact between the flexible body and the first body and the contact between the flexible body and the second body will not cause damage to the first body and the second body, and when the hinge is applied to the shower door assembly, the arrangement of the flexible body can be waterproof It prevents the water in the shower room from splashing on the first hinge and the second hinge; in addition, the flexible body can also prevent the first body and the second body from directly contacting, and prevent the first body and the second body from colliding and damaging each other. When the hinge is applied to the shower door assembly, the flexible body can prevent the first door panel from directly colliding with the second door panel, and avoid the collision and damage of the first door panel and the second door panel.

The first body is set to include a first plate and a first convex part, on the one hand, it is convenient to install with the first door panel, on the other hand, the arrangement of the first convex part is also beneficial to enlarge the first cavity in the first plate body. Upward dimension; in the same way, the second body including the second plate and the second convex part is also beneficial to increase the dimension of the second cavity in the normal direction of the second plate.

Set the distance between the first axis and the second axis to be greater than twice the distance between the first axis and the third axis, so that the first plate body and the second plate body can be rotated to a fully expanded state, that is, the first plate When the hinge is applied to the shower door assembly, when the angle between the body and the second plate body is 180°, the first door plate and the second door plate can be expanded to 180°.

In addition to using a flexible body to prevent the first body and the second body from contacting and colliding when they are folded and close, it is also possible to use the first hinge and the fourth hinge to abut when the first body and the second body are folded and close to a set angle. The connection and the second hinge abuts against the first hinge axis to restrict the first body and the second body from continuing to close together, prevent the first body and the second body from contacting and colliding, and preventing the first door panel and the second door panel from contacting and colliding.

Two second hinges and one first hinge are used, and the first hinge is arranged between the two second hinges, which is conducive to the stable movement of the hinge group. Similarly, at least two second hinges are provided. The staggered distribution of one hinge and at least two second hinges is more conducive to stable movement of the hinge group.

A flexible gasket is arranged between the first body and the first door panel, which is beneficial to uniform the force between the first door panel and the first body, and prevents the first door panel or the first body from being damaged due to local excessive force; A flexible gasket is arranged between the second body and the second door panel.
