Description

Technical Field

[0001] The present invention relates to the technical field of hinges, and more particularly to a 360-degree opening, closing, lifting and lowering hinge for a shower room. Background Art

[0002] At present, the hinge designs in the shower room industry all have limitations on the opening direction and opening angle. Since the conventional hinges can only open inwards and outwards and have a limited angle, there are rigid requirements for the customer's bathroom space, and it is not convenient to use. For example, a large opening space must be left at the position where the shower room door opens. Otherwise, when the customer places some items beside the shower room in daily life, it may cause the shower room door to be unable to open, affecting the use.

[0003] At present, most of the existing shower room hinge designs do not have a lifting function. In order to facilitate opening and closing, enough clearance for movement needs to be left between the door and the water retaining strip. During the process of using the shower room for bathing, because the clearance at the bottom of the door is too large, it is easy for the water in the shower room to splash onto the floor outside the room, and the effect of separating the dry and wet areas of the shower room is relatively poor, resulting in a relatively poor overall waterproof effect of the shower room. Moreover, most of the existing shower room hinge designs do not have an automatic closing function, so when users use the shower room, they do not enjoy a more user-friendly and comfortable experience.

[0004] Therefore, the present invention provides a 360-degree opening, closing, lifting and lowering hinge for a shower room. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

Second threaded mounting grooves threadedly connected to the threaded head are provided on the inner walls of the cylindrical cavities. Two positioning columns are fixedly provided at the ends of the long camshaft A and the long camshaft B, and positioning holes adapted to the two positioning columns are provided on the inner walls of the cylindrical cavities.

[0015] By adopting the above technical solution, it is convenient to install the locking rod to the cylindrical cavity under the action of the threaded head. At the same time, after the locking rod is installed, the long camshaft A or the long camshaft B can be effectively fixed inside the cylindrical cavity.

[0026] The beneficial effects of the present invention are as follows: For the 360-degree opening, closing, lifting and lowering hinge for a shower room of the present invention, by setting a double-axis connection assembly, an upper hinge assembly and a lower hinge assembly, after the shower room glass door is installed with this hinge, it can automatically rise during the opening process and achieve the purpose of automatic closing. Moreover, after closing, the bottom of the glass door of the shower room can contact the ground to achieve the purpose of effectively preventing water leakage in the shower room, greatly improving the user experience of personnel.

[0027] For the 360-degree opening, closing, lifting and lowering hinge for a shower room of the present invention, by setting hexagon bolts, gaskets, hinge locking blocks and rubber protective pads, when installing this hinge, the space between the upper hinge main body and the gasket and between the lower hinge main body and the gasket can be clamped on the edge of the shower room glass door, and the hexagon bolts pass through the counterbore holes on the upper hinge main body and the lower hinge main body and then pass through the installation holes reserved on the shower room glass door and are threadedly connected to the third threaded installation groove on the hinge locking block, so as to achieve the rapid installation of this hinge.

[0046] Please refer to Figure 10 A buffer airbag column 21 is fixedly disposed on the inner wall of the end cover 7 , and the end of the buffer airbag column 21 is tightly pressed against the end of the locking rod 11 .

[0047] Specifically, by providing the buffer airbag column 21, when the hinge is actually used, during the automatic closing of the shower room glass door, when the long camshaft A9 and the long camshaft B10 move, the ends of the locking rod 11 on the long camshaft A9 and the long camshaft B10 can first contact the ends of the buffer airbag column 21, and when they continue to move, the buffer airbag column 21 can be squeezed.

[0049] Specifically, by setting the reset spring 22 and the air intake and exhaust holes 16, when the hinge is actually in use and the buffer airbag column 21 is squeezed during the automatic closing process of the shower room glass door, the gas in the buffer airbag column 21 slowly discharges through the air intake and exhaust holes 16, so as to effectively buffer the reset of the shower room glass door when it closes, avoid the sudden downward reset of the shower room glass door and strong collision with the ground, thereby achieving the purpose of effectively protecting the shower room glass door. Moreover, the setting of the reset spring 22 can, on the one hand, effectively buffer, and on the other hand, suck external air into the interior of the buffer airbag column 21 through the air intake and exhaust holes 16 when the shower room glass door is opened, facilitating repeated buffer protection.

[0051] Specifically, by setting the first card slot and the second card slot, the long camshaft A9 and the short camshaft A5, as well as the long camshaft B10 and the short camshaft B13, can be mutually clamped under the action of the first card slot and the second card slot, and during the rotation of the long camshaft A9 and the long camshaft B10, the separation of the long camshaft A9 and the short camshaft A5, as well as the long camshaft B10 and the short camshaft B13, can be realized, thereby achieving the purpose of automatically lifting the shower room glass door when it is opened.

[0052] In summary, by setting the double-axis connection component 2, the upper hinge component 1 and the lower hinge component 3, when the shower room glass door is opened during the actual use of the hinge, the opened shower room glass door can be driven to lift upward. When the person's hand is separated from the glass door after the shower room glass door is opened, the purpose of automatically closing the shower room glass door can be achieved. Furthermore, after installing this hinge on the shower room glass door, it can automatically rise during the opening process and can achieve the purpose of automatic closing. Moreover, after closing, the bottom of the shower room glass door can contact the ground, achieving the purpose of effectively preventing water leakage in the shower room and greatly improving the user experience of the person.

[0053] Working principle: During the actual use of this hinge, when the shower room glass door is opened, it can drive the long camshaft A9 and the long camshaft B10 to rotate. During the rotation of the long camshaft A9 and the long camshaft B10, they can move while rotating under the action of the short camshaft A5 and the short camshaft B13 respectively, thereby driving the opened shower room glass door to lift upward. When the shower room glass door is opened and the person's hand leaves the glass door, the shower room glass door has a tendency to move downward under the action of its own gravity. At this time, under the action of the short camshaft A5 and the short camshaft B13, the long camshaft A9 and the long camshaft B10 can rotate and return to their original positions, thereby achieving the purpose of automatically closing the shower room glass door. Furthermore, after installing this hinge on the shower room glass door, it can automatically rise during the opening process and achieve the purpose of automatic closing. Moreover, after closing, the bottom of the shower room glass door can contact the ground, achieving the purpose of effectively preventing water leakage in the shower room, greatly improving the user experience of the person. And during the automatic closing process of the shower room glass door, when the buffer airbag column 21 is squeezed, the gas in the buffer airbag column 21 slowly discharges through the air inlet and outlet holes 16, thereby being able to effectively buffer the reset of the shower room glass door when it closes, avoiding the sudden downward reset of the shower room glass door and a strong collision with the ground, thus achieving the purpose of effectively protecting the shower room glass door. And the setting of the return spring 22 can, on the one hand, effectively buffer, and on the other hand, can inhale external air into the interior of the buffer airbag column 21 through the air inlet and outlet holes 16 when the shower room glass door is opened, facilitating repeated buffer protection.

The above specific implementation manner is only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
