[0032] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0033] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0034] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0035] An embodiment of this utility model provides a concealed hinge structure, such as... Figures 1-6 As shown, the device includes a first hinge assembly 100 for fixing to a base, a rotating seat 310 disposed at one end of the first hinge assembly 100, and a limiting slider 400 disposed on the rotating seat 310. It also includes a second hinge assembly 200 for fixing to the rotating door body, a decorative cover 500 slidably connected to the second hinge assembly 200, and elastic mechanisms connected to the second hinge assembly 200 and the decorative cover 500 respectively. The base can be a door frame, fixed glass, or other relatively fixed objects. The rotating door body is rotatably connected to the base through the concealed hinge structure of this embodiment, so that the opening and closing of the rotating door body can be achieved by rotating relative to the base body. Specifically, the rotating door body can be a glass door or other door types.
[0036] The second hinge assembly 200 includes a connecting seat 320, which is hinged to a rotating seat 310, thus allowing the second hinge assembly 200 to rotate relative to the first hinge assembly 100. The second hinge assembly 200 can rotate relative to the first hinge assembly 100 to both a closed and an open state. Figure 1 and Figure 2As shown, when the second hinge assembly 200 rotates relative to the first hinge assembly 100 to the closed door state, the first hinge assembly 100 and the second hinge assembly 200 are unfolded, and the base and the rotating door body are in the same plane, so that the door can be closed. As shown, Figure 3 and Figure 4 As shown, when the second hinge assembly 200 rotates relative to the first hinge assembly 100 to the open door state, the first hinge assembly 100 and the second hinge assembly 200 are at a preset angle, for example, about 90°, and the rotating door body is deflected relative to the base, so that the door can be opened.
[0037] Since the decorative cover 500 can slide relative to the second hinge assembly 200, the elastic mechanism exerts an elastic force on the decorative cover 500, so that the decorative cover 500 has a tendency to move close to the first hinge assembly 100, and one end of the decorative cover 500 remains close to the first hinge assembly 100, with only a small gap between them, which can block and hide the connecting seat 320 and the rotating seat 310. This gap makes it difficult for water in the bathroom or shower room to pass through, so that the problem of water leakage is less likely to occur, improving the waterproof performance.
[0038] During the rotation of the second hinge assembly 200 from the closed door state to the open door state, the end of the decorative cover 500 close to the first hinge assembly 100 can abut against the limiting slider 400, which will limit the decorative cover 500 from deflecting relative to the first hinge assembly 100 with the second hinge assembly 200. Under the limitation of the limiting slider 400, the decorative cover 500 will slide away from the second hinge assembly 200 against the elastic force of the elastic mechanism. Since one end of the decorative cover 500 is close to the first hinge assembly 100, the gap between them is very small, and if the decorative cover 500 does not slide relative to the second hinge assembly 200, the decorative cover 500 will touch the first hinge assembly 100. This structure can avoid interference between the decorative cover 500 and the first hinge assembly 100, ensuring smooth rotation of the second hinge assembly 200 relative to the first hinge assembly 100. During the rotation process, the gap between the end of the decorative cover 500 and the first hinge assembly 100 changes very little, and the decorative cover 500 still remains close to the first hinge assembly 100, still blocking and hiding the connecting seat 320 and the rotating seat 310.
[0039] In some embodiments, as shown in Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the limiting sliding block 400 has a guide slope 410 and a guide arc surface 420 connected with the guide slope 410, and the decorative cover 500 has a rotating arc surface 510 close to one end of the first hinge assembly 100. During the rotation of the second hinge assembly 200 from the closed state to the open state, the rotating arc surface 510 can first abut against the guide slope 410 and then slide to the guide arc surface 420. The guide slope 410 can guide the movement of the rotating arc surface 510, and the guide arc surface 420 facilitates the rotation of the rotating arc surface 510 on its surface, so as to facilitate the rotation of the entire decorative cover 500 to the open state.
[0040] In some embodiments, as shown in Figure 1 and Figure 7 As shown, the second hinge assembly 200 includes a first clamping cover 210 and a second clamping cover 220, which are used to clamp and fix on the rotating door body, and the clamping and fixing manner is more stable. The decorative cover 500 is in sliding connection with the second clamping cover 220, one end of the elastic mechanism 600 is connected with the second clamping cover 220, and the other end is connected with the decorative cover 500. The elastic mechanism 600 can provide elastic force to the decorative cover 500, so that the decorative cover 500 elastically slides.
[0041] The first clamping cover 210 and the second clamping cover 220 can be connected by screws, and the screws can pass through the rotating door body. By screwing the screws, the first clamping cover 210 and the second clamping cover 220 can clamp the rotating door body.
[0042] Further, the second clamping cover 220 is provided with a guide groove 221, and the extension direction of the guide groove 221 is parallel to the sliding direction of the decorative cover 500 relative to the second clamping cover 220. The elastic mechanism 600 includes a spring located in the guide groove 221. The guide groove 221 guides the elastic movement of the spring, so that the spring stably provides elastic force in the direction parallel to the sliding direction of the decorative cover 500 relative to the second clamping cover 220, avoiding displacement or deviation of the spring.
[0043] In some embodiments, the second hinge assembly 200 further includes a first buffer pad 230 located inside the first clamping cover 210 and a second buffer pad 240 located inside the second clamping cover 220. When the first clamping cover 210 and the second clamping cover 220 clamp and fix the rotating door body, the first buffer pad 230 is arranged between the first clamping cover 210 and the rotating door body, and the second buffer pad 240 is arranged between the second clamping cover 220 and the rotating door body. This can provide buffer protection for the rotating door body, avoiding damage to the rotating door body.
[0044] At the same time, the second buffer pad 240 covers the guide groove 221, and the spring is difficult to come out of the guide groove 221, so as to stably install the spring.
[0045] In some embodiments, the top of the decorative cover 500 has a downwardly protruding upper slide strip 520, the bottom of the decorative cover 500 has an upwardly protruding lower slide strip 530, the top of the second clamping cover 220 has an upper slide groove 222, the bottom of the second clamping cover 220 has a lower slide groove 223, the extension directions of the upper slide groove 222 and the lower slide groove 223 are parallel to the direction in which the decorative cover 500 slides relative to the second clamping cover 220, the upper slide strip 520 and the upper slide groove 222 slide fit, the lower slide strip 530 and the lower slide groove 223 slide fit, thereby enabling the decorative cover 500 to slide smoothly relative to the second clamping cover 220.
[0046] In some embodiments, as shown in Figure 3 、 Figure 8 、 Figure 9 and Figure 10 , the connecting seat 320 is located above the rotating seat 310, the bottom of the connecting seat 320 is fixed with a rotating shaft 330 and a lifting member 340 sleeved outside the rotating shaft 330, the bottom of the lifting member 340 is provided with a downwardly protruding upper protrusion 341. The rotating seat 310 is provided with a through hole 311, the rotating shaft 330 is inserted into the through hole 311 and can rotate and slide in the through hole 311. When the second hinge assembly 200 rotates relative to the first hinge assembly 100, the rotating shaft 330 rotates in the through hole 311, thereby realizing the rotational connection of the second hinge assembly 200 and the first hinge assembly 100. At the same time, the rotating shaft 330 can slide in the through hole 311, which provides conditions for the lifting of the connecting seat 320.
[0047] The top of the rotating seat 310 is fixed with a lower lifting member 350, the lower lifting member 350 is arranged around the through hole 311, and the top of the lower lifting member 350 is provided with an upwardly protruding lower protrusion 351. The lifting member 340 is placed on the lower lifting member 350, and due to the weight of the rotating door body loaded on the second hinge assembly 200, the lifting member 340 will be tightly attached to the lower lifting member 350.
[0048] As shown in Figure 9 , at this time, the door is in a closed state, the upper protrusion 341 does not abut against the top of the lower protrusion 351, and the upper protrusion 341 is in a low height state.
[0049] During the rotation of the second hinge assembly 200 from the closed state to the open state, the upper protrusion 341 can move along the top surface of the lower lifting member 350, and gradually move from the bottom to the top of the lower protrusion 351. As shown in Figure 10 , at this time, the door is in an open state, the upper protrusion 341 abuts against the top of the lower protrusion 351, the upper protrusion 341 is lifted, and is in a high height state.
[0050] Since the upper protrusion 341 is fixed on the connecting seat 320, and the connecting seat 320 is fixed on the rotating door body, when the upper protrusion 341 is lifted, the rotating door body will be lifted correspondingly. The significance of such an arrangement is that the bottom of the rotating door of the bathroom or shower room is provided with a waterproof strip in contact with the ground to improve waterproofness, but the friction between the waterproof strip and the ground will increase the rotating and fixing friction of the rotating door body. In the door opening process of the embodiment, the rotating door body will be gradually lifted, so that the waterproof strip at the bottom of the rotating door body is away from the ground, the friction is reduced, and then the user can open and close the door conveniently.
[0051] Further, the upper protrusion 341 and the lower protrusion 351 are both provided with two, and when the second hinge assembly 200 is in the closed state, the two upper protrusions 341 are located between the two lower protrusions 351 respectively. For the second hinge assembly 200 in the closed state, rotating in any direction can make the upper protrusion 341 abut against the top of the lower protrusion 351, so that the rotating door can be lifted in the process of bidirectional opening of the rotating door, which is more convenient for the user to open and close the door.
[0052] In the embodiment, the connecting seat 320 can be provided with two, and the two connecting seats 320 can be located above and below the rotating seat 310 respectively, so as to avoid the rotating shaft 330 from being detached from the through hole 311.
[0053] In some embodiments, as shown in Figure 3 and Figure 8 The first hinge assembly 100 includes a first clamping plate 110 and a second clamping plate 120, and the first clamping plate 110 and the second clamping plate 120 are used to clamp and fix on the base body. The clamping and fixing can make the entire first hinge assembly 100 stably fixed on the base body. The rotating seat 310 is connected with the second clamping plate 120, and one end of the decorative cover 500 is close to the second clamping plate 120.
[0054] The first clamping plate 110 and the second clamping plate 120 can be connected through screws, and the screws can pass through the base body. By screwing the screws, the first clamping plate 110 and the second clamping plate 120 can clamp the base body.
[0055] The terms and words used in the above description and claims are not limited by the literal meaning, but are used by the applicant to enable a clear and consistent understanding of the present application. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present application is only for illustration, not for limitation of the present application as defined by the appended claims and their equivalents.
