Description

Technical Field

[0001] The utility model relates to the technical field of shower rooms, in particular to an anti-slip rotating shaft core, a rotating door structure and a door. Background Art

[0002] Existing swing door designs in shower rooms feature a door leaf that pivots relative to the door frame around a raised axis on the door hinge. The door leaf and the hinge profile in the hinge are often secured with glue. This installation method leaves the glass panel suspended in mid-air. Given the inherent weight of the door leaf, if the glue loses its original viscosity due to aging or environmental factors, it may no longer securely support the door leaf, putting the previously securely connected glass panel at risk of detachment. Once the glass falls due to glue failure, it can easily cause personal injury. Utility Model Content

[0007] The third technical solution is based on the second technical solution, which includes a rotating shaft profile, a first rotating shaft core and the above-mentioned anti-slip rotating shaft core. The bodies of the first rotating shaft core and the anti-slip rotating shaft core are respectively inserted into the two ends of the rotating shaft profile to form the door shaft part together.

[0008] The fourth technical solution is based on the third technical solution, wherein the first shaft connecting portion is a convex shaft; and the second shaft connecting portion is a shaft hole.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the shaft profile, the first shaft core and the anti-slip shaft core are all provided with the shaft hole.

[0010] The sixth technical solution is based on the third technical solution, wherein the anti-slip shaft core is inserted into the top end of the shaft profile along the first direction.

[0011] The seventh technical solution is based on the third technical solution, wherein the anti-slip rotating shaft core and the first rotating shaft core are both provided with a limiting groove extending along the first direction and opening toward the second direction, and the door leaf is plugged into the limiting groove along the second direction.

[0012] The eighth technical solution is based on any one of the second to seventh technical solutions, wherein a door comprises a door frame and a door leaf both extending along a first direction, and the door leaf and the door frame are rotationally connected using the above-mentioned rotating door structure.

[0013] The ninth technical solution is based on the eighth technical solution, wherein the rotating shaft profile is interference-connected with the first rotating shaft core and the anti-slip rotating shaft core.

[0014] The tenth technical solution is based on the eighth technical solution, wherein the shaft profile is provided with an installation groove extending along the first direction and opening toward the second direction, and the door leaf is made of glass and is fixed in the installation groove by a glass adhesive layer.

[0015] From the above description of the various embodiments of the present invention, it can be seen that compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0016] In the first technical solution and related embodiments, an anti-slip protrusion is provided on the anti-slip rotating shaft core, and the protrusion is plugged into and matched with the groove opening along the first direction on the door leaf, thereby forming a stable anti-slip mechanism, which prevents the door leaf from detaching from the rotating shaft profile along the second direction when subjected to external force, thereby improving the safety and reliability of the rotating door structure. In addition to the anti-slip protrusion, the extension portion of the anti-slip rotating shaft core is also provided with two clamping portions, which can clamp the door leaf along the third direction (perpendicular to both the first direction and the second direction), thereby preventing the door leaf from shaking in the third direction, avoiding the door leaf from being offset or falling out during the rotation process, and ensuring the stability and safety of the door leaf movement. The main body and the extension portion of the anti-slip rotating shaft core are connected as one body to ensure the strength of the extension portion. The main body is plugged into and matched with the top end of the rotating shaft profile along the first direction, and the installation is simple and quick. At the same time, the anti-slip protrusion and the clamping portion of the extension portion are also easy to dock with the groove and corresponding parts on the door leaf, thereby reducing the difficulty and cost of installation.

[0017] In the second technical solution and related embodiments, the revolving door structure realizes multiple anti-slip protection for the door leaf by arranging an extension portion outside the door shaft portion and integrating an anti-slip protrusion and a clamping portion on the extension portion, thereby improving the safety and reliability of the revolving door structure. Specifically, the anti-slip protrusion is plugged into and matched with the groove opening along the first direction on the door leaf, preventing the door leaf from accidentally slipping out along the second direction (i.e., the direction perpendicular to the direction in which the door leaf is embedded in the door shaft portion). At the same time, the clamping portion clamps and limits the door leaf along the third direction (i.e., the direction perpendicular to the first two directions), preventing the door leaf from shaking in the third direction, avoiding the possible deviation or slipping out of the door leaf during the rotation process, and ensuring the smoothness and safety of the door leaf movement. In this structural design, the groove on the door leaf does not need to be opened too large, maintaining the aesthetics of the door leaf. During installation, it is only necessary to embed the door leaf into the door shaft portion along the second direction and ensure that the anti-slip protrusion is correctly docked with the groove. This installation method can reduce the difficulty of installation and improve installation efficiency.

[0018] In the third technical solution and related embodiments, since the main body of the anti-slip rotating shaft core is inserted into the rotating shaft profile, and the extension is designed outside the rotating shaft profile, this layout not only maintains the structural integrity of the anti-slip rotating shaft core body, but also avoids interference or influence of the extension on the main body structure, and does not affect the strength and stability of the anti-slip rotating shaft core body. This structure also reduces the difficulty of manufacturing the anti-slip rotating shaft core.

[0019] In the fourth technical solution and related embodiments, the combination of the protruding shaft and the shaft hole optimizes space utilization within the revolving door structure. Because both the protruding shaft and the shaft hole are compactly designed, they achieve effective connection without taking up excessive space. This also simplifies and speeds the connection between the various components of the revolving door structure and the door frame.

[0020] In the fifth technical solution and related embodiments, the rotating shaft profile, the first rotating shaft core and the anti-slip rotating shaft core rotate in cooperation with the convex shaft of the door frame through the shaft hole to realize the opening and closing of the door leaf.

[0021] In the sixth technical solution and related embodiments, the anti-slip shaft core is inserted into the top end of the shaft profile along the first direction, effectively preventing the top area of ​​the door leaf from slipping out. This design ensures the stability of the door leaf while also considering cost and manufacturing simplicity. Because the top of the door leaf is often more susceptible to external forces during opening and closing, the extension of the anti-slip shaft core can specifically enhance the anti-slip effect in this area.

[0022] In the seventh technical solution and related embodiments, since the first rotating shaft core and the anti-slip rotating shaft core are respectively inserted into the two ends of the rotating shaft profile, the two ends of the door leaf are respectively plugged into and matched with the upper and lower limit grooves along the second direction, which further prevents the door leaf from shaking in the third direction, avoids the possible deviation or disengagement of the door leaf during the rotation process, and ensures the smoothness and safety of the door leaf movement.

[0023] In the eighth technical solution and related embodiments, the rotating door structure is used to install the door, ensuring the stability and safety of the door during use.

[0024] In the ninth technical solution and related embodiments, the interference fit method is used to ensure a tight fit between the rotating shaft profile and the first rotating shaft core and the anti-slip rotating shaft core to prevent loosening and falling off.

[0025] In the tenth technical solution and related embodiments, the door leaf is fixed in the installation groove by a glass adhesive layer, thereby enhancing the connection strength between the door leaf and the rotating profile. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Example 1

[0047] An anti-slip shaft core 4 is used to prevent the door leaf 2 from escaping from the shaft profile 5 along the second direction. The shaft profile 5 extends along the first direction, and the door leaf 2 is plugged into the shaft profile 5 along the second direction. Figure 4 As shown, the door leaf 2 is provided with a groove 17 opening along the first direction; the anti-slip shaft core 4 is provided with a main body and an extension part 3 fixed to each other, and the main body is suitable for plugging and matching with the top end of the shaft profile 5 along the first direction; the extension part 3 is provided with an anti-slip protrusion 12 and two clamping parts 13, and the anti-slip protrusion 12 is suitable for plugging and matching with the groove 17 to prevent the door leaf 2 from escaping from the shaft profile 5 along the second direction, and the two clamping parts 13 are suitable for clamping the door leaf 2 along the third direction and interference fitting.

[0048] In this embodiment, an anti-slip protrusion 12 is provided on the anti-slip rotating shaft core 4, and the protrusion is plugged into and matched with the groove 17 opening along the first direction on the door leaf 2, thereby forming a stable structure, preventing the door leaf 2 from escaping from the rotating shaft profile 5 along the second direction when subjected to external force, thereby improving the safety and reliability of the rotating door structure. In addition to the anti-slip protrusion 12, the extension 3 of the anti-slip rotating shaft core 4 is also provided with two clamping parts 13, which can clamp the door leaf 2 along the third direction (perpendicular to both the first direction and the second direction), preventing the door leaf 2 from shaking in the third direction, avoiding the door leaf 2 from deviating or falling out during the rotation process, and ensuring the stability and safety of the movement of the door leaf 2. The main body and the extension 3 in the anti-slip rotating shaft core 4 are connected as one body to ensure the strength of the extension 3. The main body is plugged into and matched with the top end of the rotating shaft profile 5 along the first direction, and the installation is simple and quick. At the same time, the anti-slip protrusion 12 and the clamping part 13 of the extension 3 are also easy to dock with the groove 17 and the corresponding parts on the door leaf 2, reducing the difficulty and cost of installation. The two clamping parts 13 form an interference fit with the door leaf 2, further enhancing the anti-falling effect. The first direction (x), the second direction (y) and the third direction (z) are perpendicular to each other.

[0049] Example 2

[0050] See also Figures 1 to 10 ,like Figure 1 and Figure 11 As shown, a rotating door structure is used to rotatably connect the door leaf 2 to the door frame 7. The door frame 7 is provided with first shaft connecting parts opposite to each other along a first direction; specifically, the door frame 7 is provided with first shaft connecting parts opposite to each other at both ends. In this embodiment, the first shaft connecting part is designed as a protruding shaft 18, which is used to rotatably cooperate with the second shaft connecting part of the door shaft part 1. Figure 4 As shown, the door leaf 2 is provided with a groove 17 opening along a first direction; specifically, the size and shape of the connection between the door leaf 2 and the door frame 7 must match the door frame 7 to ensure smooth rotation. The rotating door structure includes a door shaft portion 1 and an extension portion 3.

[0051] The door hinge 1 has second connecting portions at both ends along the first direction, which are rotatably coupled to the two first connecting portions. The door leaf 2 is embedded in the door hinge 1 along the second direction. Specifically, the second connecting portion is a shaft hole. The combination of the protruding shaft 18 and the shaft hole optimizes the space utilization of the rotating door structure.

[0052] like Figure 2 and Figure 3 As shown, the extension portion 3 extends from one end of the door shaft portion 1 along the second direction and is provided with an anti-slip protrusion 12 and two clamping portions 13. The anti-slip protrusion 12 is plugged into the groove 17.

[0053] The clamping portion 13, such as Figure 5As shown, the two clamping portions 13 clamp the door leaf 2 along the third direction. Specifically, the two clamping portions 13 clamp the anti-slip protrusion 12 along the third direction and are plugged and matched with the door leaf 2 along the second direction.

[0054] In this embodiment, the revolving door structure provides multiple anti-slip protection for the door leaf 2 by providing an extension portion 3 outside the door shaft portion 1 and integrating an anti-slip protrusion 12 and a clamping portion 13 on the extension portion 3, thereby improving the safety and reliability of the revolving door structure. Specifically, the anti-slip protrusion 12 engages with a groove 17 on the door leaf 2 that opens along a first direction, preventing the door leaf 2 from slipping out along a second direction (i.e., perpendicular to the direction in which the door leaf 2 is embedded in the door shaft portion 1). At the same time, the clamping portion 13 clamps and limits the door leaf 2 along a third direction (i.e., a direction perpendicular to both of the first two directions), preventing the door leaf 2 from shaking in the third direction, avoiding the possibility of the door leaf 2 shifting or slipping out during rotation, and ensuring the smooth and safe movement of the door leaf 2. In this structural design, the groove 17 on the door leaf 2 does not need to be opened too large, which maintains the aesthetics of the door leaf 2 and prevents dust from entering the groove 17. During installation, the door leaf 2 only needs to be embedded in the door shaft portion 1 along the second direction and ensure that the anti-slip protrusion 12 is properly aligned with the groove 17. This installation method can reduce installation difficulty and improve installation efficiency.

[0055] Specifically, the rotating door structure includes a rotating shaft profile 5, a first rotating shaft core 6 and an anti-slip rotating shaft core 4.

[0056] like Figure 5 As shown, the anti-slip rotating shaft core 4 is provided with a main body and the above-mentioned extension portion 3. The first rotating shaft core 6 and the main body of the anti-slip rotating shaft core 4 are respectively inserted into the two ends of the rotating shaft profile 5, and together form the above-mentioned door shaft portion 1. The main body and the extension portion 3 in the anti-slip rotating shaft core 4 are integrally formed to ensure the strength of the extension portion 3.

[0057] like Figure 7 As shown, the shaft profile 5 is a profile extending along the first direction, as shown in FIG. Figure 8 As shown, the first shaft core 6 and the anti-slip shaft core 4 are suitable for being plugged into the shaft profile 5. The shaft profile 5 is provided with a third shaft hole 20 that is rotatably matched with the protruding shaft 18, and an opening is provided along the second direction at the third shaft hole 20 to form a mounting groove 11 for the door leaf 2 to enter.

[0058] like Figure 6 As shown, the first rotating shaft core 6 is provided with a circumferential wall suitable for inserting the rotating shaft profile 5, and its circumferential wall is provided with an opening along the second direction to form a first limiting groove 14 for the door leaf 2 to enter. The middle part of the first rotating shaft core 6 body is provided with a first shaft hole 15 that rotates with the protruding shaft 18.

[0059] like Figure 5As shown, the anti-slip rotation core 4 is provided with a circumferential ring wall suitable for inserting the rotation shaft profile 5, and its ring wall is provided with an opening along the second direction to form a second limiting groove 21 for the door leaf 2 to enter, and the extension portion 3 is located outside the second limiting groove 21 along the second direction. The middle part of the anti-slip rotation core 4 body is provided with a second shaft hole 16 that rotates with the protruding shaft 18.

[0060] The anti-slip rotating shaft core 4 and the first rotating shaft core 6 are both provided with a limiting groove extending in the first direction and opening in the second direction, and the door leaf 2 is plugged into and matched with the limiting groove along the second direction. Since the first rotating shaft core 6 and the anti-slip rotating shaft core 4 are respectively plugged into the two ends of the rotating shaft profile 5, and the two ends of the door leaf 2 are respectively plugged into and matched with the limiting grooves at the upper and lower ends along the second direction, the shaking of the door leaf 2 in the third direction is further prevented, and the possible deviation or disengagement of the door leaf 2 during the rotation process is avoided, thereby ensuring the smooth and safe movement of the door leaf 2.

[0061] The rotating shaft profile 5, the first rotating shaft core 6 and the anti-slip rotating shaft core 4 rotate and cooperate with the convex shaft 18 of the door frame 7 through the shaft hole to realize the opening and closing of the door leaf 2. Specifically, the anti-slip rotating shaft core 4 is inserted into the top end of the rotating shaft profile 5 along the first direction, and the first rotating shaft core 6 is inserted into the bottom end of the rotating shaft profile 5 along the first direction. By inserting the anti-slip rotating shaft core 4 into the top end of the rotating shaft profile 5 along the first direction, effective anti-slipping of the top area of ​​the door leaf 2 is achieved. Even if the glue fails, it can prevent the door leaf 2 from falling off the rotating shaft profile 5, effectively protecting the personal safety of the user. This design not only ensures the stability of the door leaf 2, but also takes into account the cost and ease of manufacturing. Since the top of the door leaf 2 is often more susceptible to the influence of external forces during the opening and closing process, the extension portion 3 of the anti-slip rotating shaft core 4 can specifically enhance the anti-slip effect of this area. The bottom end of the rotating shaft profile 5 along the first direction is close to the ground. The bottom of the door leaf 2 is not easily affected by external forces during the opening and closing process. Therefore, the first rotating shaft core 6 does not need the extension part 3.

[0062] Example 3

[0063] A door, such as Figure 10 As shown, it includes a door frame 7 and a door leaf 2, both extending in a first direction. The door leaf 2 and door frame 7 are rotatably connected using the aforementioned pivoting door structure. This ensures that the door leaf 2 can smoothly rotate about the door shaft 1. At the same time, the anti-slip protrusion 12 and clamping portion 13 of the anti-slip rotation core 4 effectively prevent the door leaf 2 from falling off. Using this pivoting door structure to install the door ensures stability and safety during use.

[0064] like Figure 11 and Figure 12As shown, the door includes a rotating shaft seat 10, which is provided with first shaft connection parts opposite to each other along a first direction. Specifically, there are two rotating shaft seats 10, which are installed at the top and bottom ends of the door frame 7 along the first direction. The first shaft connection part is a protruding shaft 18. The protruding shaft 18 is rotatably engaged with the first shaft hole 15 of the first rotating shaft core 6, the second shaft hole 16 of the anti-slip rotating shaft core 4, and the third shaft hole 20 of the rotating shaft profile 5. Figure 11 As shown, the shaft seat 10 is fixed to the door frame 7 by screws 19.

[0065] The rotating shaft profile 5 is inserted into the first rotating shaft core 6 and the anti-slip rotating shaft core 4 through interference. Figure 3 and Figure 9 As shown, the interference fit connection method can ensure the close fit between the rotating shaft profile 5 and the first rotating shaft core 6 and the anti-slip rotating shaft core 4 to prevent loosening and falling off.

[0066] The rotating shaft profile 5 is provided with a mounting groove 11 extending along a first direction and opening toward a second direction. In this embodiment, the door leaf 2 is made of glass and is fixed in the mounting groove 11 by a glass adhesive layer. Specifically, the mounting groove 11 is a glue groove, and the door leaf 2 is fixed in the mounting groove 11 by the glass adhesive layer, thereby enhancing the connection strength between the door leaf 2 and the rotating profile.

[0067] The specific assembly process is as follows:

[0068] First, insert the first shaft core 6 into one end of the shaft profile 5 for interference fit, and ensure that its first shaft hole 15 is aligned with the protruding shaft 18 at one end of the door frame 7. Then, apply glass glue to the installation groove 11 of the shaft profile 5, and install the door leaf 2 into the shaft profile 5 along the second direction.

[0069] Secondly, the main body of the anti-slip shaft core 4 is inserted into the other end of the shaft profile 5 for interference fitting, and it is also ensured that it corresponds to the position of the convex shaft 18 at the other end of the door frame 7. At this point, the shaft profile 5, the first shaft core 6 and the anti-slip shaft core 4 together form the door shaft portion 1.

[0070] Finally, ensure that the groove 17 of the door leaf 2 is aligned with the anti-slip protrusion 12 of the anti-slip rotating shaft core 4 and plugged into place, and enable the two clamping parts 13 to clamp the door leaf 2 along the third direction.

[0071] The above description and embodiments are used to explain the scope of protection of the utility model, but do not constitute a limitation on the scope of protection of the utility model. Based on the enlightenment of the utility model or the above embodiments, modifications, equivalent replacements, or other improvements to the embodiments of the utility model or part of the technical features thereof that can be obtained by ordinary technicians in this field through logical analysis, reasoning, or limited experiments in combination with common knowledge, ordinary technical knowledge in this field and / or existing technology should be included in the scope of protection of the utility model.
