Description

Technical Field

[0001] The invention relates to the field of bathrooms, and in particular to a rotating shaft structure and a shower door. Background Art

[0002] As people's living standards improve, installing a shower room in the bathroom is becoming more and more popular. Installing a shower room in the bathroom can form an independent shower space in the bathroom, which can better separate wet and dry areas, keep warm in cold weather, and showering in the shower room does not affect the use of other appliances in the bathroom, such as toiletries and toilets. Existing shower room doors can generally be classified into sliding doors and revolving doors. Sliding doors generally require a longer track for the sliding door to move linearly between the open position and the closed position, while revolving doors generally have a relatively simple structure and do not require a track. The movable door can be rotated by simply connecting the fixed door and the movable door through a hinge or a rotating shaft.

[0003] People have higher and higher requirements for the functionality of rotary shower doors. In order to prevent water from leaking out when the shower room is in use, it is usually necessary to set a waterproof strip at the door of the shower room. However, most rotary shower doors can only use a rotating shaft to achieve a simple rotation function. The movable door often rubs against the waterproof strip when opening and closing the door, resulting in unsmooth opening and closing of the door, and the waterproof strip is easily damaged. In addition, in order to prevent the water droplets on the inner surface of the movable door from flowing out of the shower room after opening the door, especially after opening the door outward, a return water structure can be added to the lower end of the movable door so that the water droplets can gather at the lower end of the movable door and flow back into the shower room. However, the existing return water structure, such as the return water structure disclosed in the rotating shaft structure of the existing patent application CN108561053, in order to ensure that the water flows back into the shower room, most of them need to extend a certain distance from the lower end of the movable door into the shower room. This structure is easy to interfere with the adjacent fixed door or wall when the rotary shower door is opened inward, resulting in the inability to open inward. In addition, this structure affects the appearance and is sometimes easily damaged by accidental collision. In addition, after the movable door is connected to the rotating shaft in the existing rotary shower door, the connecting portion of the rotating shaft and the movable door will be raised or sunken from the plate surface of the movable door, which not only affects the appearance, but also easily accumulates dust and dirt, affecting cleaning and hygiene.

[0024] The present invention is further described in detail below with reference to the accompanying drawings and specific implementation modes. DETAILED DESCRIPTION

[0025] like Figures 1 to 4As shown, this embodiment provides a rotating shaft structure, which is mainly used in rotating shower doors that open inside and outside, and can also be used in other fields. The rotating shaft structure includes a base 100 and a rotating block 200. The upper end of the base 100 includes a rotating shaft 110, and the lower end of the rotating block 200 includes a matching hole 210. The matching hole 210 is used to match the rotating shaft 110. The top of the rotating shaft 110 includes a first platform 111 and a second platform 112 that are arranged opposite to each other. The first platform 111 is higher than the second platform 112. The two ends of the first platform 111 and the two ends of the second platform 112 in the circumferential direction of the top of the rotating shaft 110 are connected by a transition surface 113, and the transition surface 113 is an inclined surface or an arc surface. The bottom of the matching hole 210 includes a protrusion 211 and a recessed portion 212 that are arranged opposite to each other and connected to each other in the circumferential direction. The protrusion 211 is closer to the opening of the hole than the recessed portion 212. The matching hole 210 can rotate forward and backward along the circumferential direction relative to the rotating shaft 110, so that the protrusion 211 moves between the first platform 111, the transition surface 113 and the second platform 112. When the protrusion 211 moves to match with the second platform 112, the recessed portion 212 can accommodate the first platform 111. Among them, the first platform 111 and the second platform 112 adopt the platform mode, that is, the first platform 111 and the second platform 112 are planes with a certain area, so that when the protrusion 211 reaches the first platform 111 or the second platform 112, it can stop on the first platform 111 or the second platform 112 relatively stably. The protrusion 211 and the recessed portion 212 can also be planes with a certain area, or other shapes such as arc surfaces, etc. The protrusion 211 and the recessed portion 212 can also be transitioned by an arc surface or an inclined surface, and there is no need for special restrictions in this embodiment.

In the embodiment of the rotating shaft structure and the embodiment of the shower door, the base 100 is used to be connected to the fixed door 300 or the wall, and the rotating block 200 is connected to the movable door 400. When the movable door 400 is pushed to rotate, the rotating block 200 can rotate relative to the base 100. When the protrusion 211 moves to the first platform 111 along the transition surface 113, the rotating block 200 rises relative to the base 100 to prevent the movable door 400 from scratching the waterproof strip 500 when opening inside and outside, and the protrusion 211 can stop smoothly on the first platform 111 to maintain the state of opening the door. When the protrusion 211 moves to the second platform 112 along the transition surface 113, the rotating block 200 can automatically descend under the gravity of the movable door 400, etc., to promote the closing of the movable door 400.

The transverse frame positioning portion 230 is used to connect the transverse frame 410 of the movable door 400, and the extending direction of the transverse frame positioning portion 230 is the extending direction of the movable door 300. The transverse frame positioning portion 230, for example, extends into the transverse frame 410 of the movable door 400 for fixing. With the above structure, the rotating shaft 210 can be close to the edge of the fixed door 300. Preferably, the rotating block 200 also includes a return water groove 240 arranged on the second side of the main body 220, the second side of the main body 220 is adjacent to the first side of the main body 220, the return water groove 240 extends in a direction parallel to the transverse frame positioning portion 230, and the end of the return water groove 240 away from the transverse frame positioning portion exceeds the center line of the matching hole 210 in the direction away from the transverse frame positioning portion 230 and does not exceed the end face 221 of the main body 220, and a downward notch 241 is provided at the end.

The waterproof strip 500 can be adjusted to a suitable position by conventional technical means, for example, adjusted to contact the outer side of the lower end of the movable door 400 or to contact the middle of the lower end of the movable door 400, so that when the movable door 400 is closed, the lower end of the movable door 400 contacts the waterproof strip 500 for waterproof sealing. When the movable door 400 is opened, the gap of the water return groove 240 can guide the water to the inner side of the waterproof strip 500. Preferably, the waterproof strip 500 extends outwards from the third side of the seat body 120, and the third side of the seat body 120 is opposite to the first side of the seat body 120.
