Description

Technical Field

[0001] The utility model relates to the technical field related to rotating shaft doors, and in particular to a rotating shaft mechanism and a rotating shaft door. Background Art

[0002] With the continuous development of modern architectural design and interior decoration, pivot doors, as a common door type, are increasingly used. However, there are many problems with the pivot mechanism of traditional pivot doors, which limit their application and development in the market.

[0003] Traditional pivot door pivot mechanisms, such as nut damping structure pivots, can provide certain stability and damping effects, but due to their complex structures, including multiple parts such as movable frames, fixed frames, connecting shafts, spring washers, etc., the overall assembly space is large, the manufacturing process is complex, the production efficiency is low, and the cost is high. These problems not only increase the production cost of pivot doors, but may also lead to unstable product performance and a short service life.

[0004] In addition, the traditional pivot door pivot mechanism also faces many challenges during the assembly process. Due to the large number of parts and the complex assembly process, it is easy to cause assembly errors, affecting the stability and use effect of the pivot door. At the same time, since the pivot door needs to occupy a large space when opening and closing, it also limits its use in certain application scenarios with limited space. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the utility model provides a rotating shaft mechanism and a rotating shaft door, which can solve the problems of complex rotating shaft structure and difficult assembly.

[0006] The technical solution adopted by the utility model to solve the problem is:

[0007] A rotating shaft mechanism comprises: a first connecting member; a second connecting member; of the two opposite side surfaces of the first connecting member and the second connecting member, one side surface is convexly provided with a plug connector, and the other side surface is convexly provided with a plug socket, and the plug connector is rotatably connected to the plug socket; a first clearance groove is provided on one side of the plug connector, and a second limiting hole is provided on one side of the plug socket corresponding to the first clearance groove, and the second limiting hole is penetrated by a limiting member that is engaged with the first clearance groove.

[0008] By adopting the above solution, the door can be opened and closed by only two main parts, the first connecting member and the second connecting member, and the plug connector and the plug socket are connected by rotation. This design significantly simplifies the structure of the rotating shaft mechanism. This simplification not only reduces the manufacturing cost, but also improves the assembly efficiency; at the same time, the design of the first clearance groove and the second limiting hole, combined with the clamping of the limiting member, can effectively limit the rotation angle of the first connecting member relative to the second connecting member. This design ensures the stability and reliability of the door during opening and closing.

[0009] Furthermore, the first connector includes: an assembly portion, the plug connector is arranged on the assembly portion, and the assembly portion is also provided with an assembly hole adjacent to the plug connector interval; a bending portion, the bending portion is bent to a side away from the plug connector, and the bending portion is vertically connected to the assembly portion.

[0010] By adopting the above scheme, the assembly hole may be used for fixed connection with the door body, such as connecting with the door body through screws or other fasteners through the assembly hole, thereby increasing the connection stability and firmness between the first connecting member and the door body. The bent portion can fit against the side wall of the door body, which helps to quickly position it in front of the fastener, and can adapt to different door frame and door body installation environments, increasing the convenience and adaptability of installation.

[0011] Furthermore, the plug connector includes: a rotating shaft portion, which is used to be inserted into the socket; and an abutment platform, which is located between the rotating shaft portion and the first connecting member, and the orthographic projection area of ​​the abutment platform on the first connecting member is larger than the orthographic projection area of ​​the rotating shaft portion on the first connecting member.

[0012] By adopting the above solution, the abutment platform can keep the hinge door stably supporting the door body when opening and closing, reduce the shaking and noise of the door body, and thus enhance the stability of the hinge mechanism; by increasing the area of ​​the abutment platform, the weight of the door body and the force during opening and closing can be more effectively transferred to the socket. This helps to optimize the force distribution, reduce the concentration of local stress, and further improve the durability and service life of the hinge mechanism.

[0013] Furthermore, a chamfer is provided at the end of the rotating shaft portion and / or at a connection point between the abutting platform and the first connecting member.

[0014] By adopting the above solution, the friction between these components during the rotation process can be reduced, thereby reducing wear and extending the service life of the shaft mechanism; at the same time, the chamfer design can guide the smooth insertion of the shaft part during assembly, and the chamfer can serve as a guide surface to help the shaft part quickly and accurately position the socket.

[0015] Furthermore, the first easing groove is arranged on the side of the rotating shaft portion, the orthographic projection of the first easing groove on the first connecting member is fan-shaped, and the central angle range of the first easing groove is 90°-270°.

[0016] By adopting the above solution, a flexible door rotation angle limit function is provided. This design can be adjusted according to specific usage scenarios and needs to meet different safety and space utilization requirements.

[0017] Furthermore, the socket has a cylindrical groove, the second limiting hole is connected to the cylindrical groove, and the inner diameter of the cylindrical groove is larger than the diameter of the rotating shaft portion.

[0018] By adopting the above solution, the rotating shaft part can have enough space to rotate in the cylindrical groove without being subjected to excessive friction or resistance, thus ensuring that the door body is stable and smooth during the opening and closing process.

[0019] Furthermore, an abutment surface axially opposite to the second limiting hole is provided in the first clearance groove, and the abutment surface is used to abut against the limiting member.

[0020] By adopting the above scheme, when the limiting member passes through the second limiting hole and abuts against the abutment surface in the first clearance groove, the rotation angle of the door body will be limited; at the same time, the abutment surface provides a surface that is in stable contact with the limiting member, ensuring that when the door body is rotated to a specific angle, the limiting member can stay stably in this position to prevent the door body from rotating accidentally.

[0021] Furthermore, the first connecting member and the plug connector are integrally formed.

[0022] By adopting the above solution, the joint between the first connector and the plug connector and potential assembly problems are reduced, the stability and reliability of the entire connection structure are improved, and at the same time the production cycle is shortened, the production efficiency is improved, and the production cost is reduced.

[0023] Furthermore, the second connecting member and the socket are integrally formed.

[0024] By adopting the above solution, the joint between the second connector and the socket and potential assembly problems are reduced, the stability and reliability of the entire connection structure are improved, and at the same time the production cycle is shortened, the production efficiency is improved, and the production cost is reduced.

[0025] A pivot door comprises a door frame, a door body and a pivot mechanism, wherein the first connecting member is fixedly connected to the door body, and the second connecting member is fixedly connected to the door frame.

[0026] By adopting the above solution, the number of rotating shaft parts of the rotating shaft door is simplified and the assembly efficiency is improved.

[0027] In summary, the rotary shaft mechanism and rotary shaft door provided by the utility model have the following technical effects:

[0028] 1. The shaft mechanism only includes two main parts, the first connecting member and the second connecting member, which significantly simplifies the structure of the shaft mechanism and reduces the number of parts, which not only reduces the manufacturing cost, but also reduces the assembly error caused by the large number of parts, thereby improving the product quality;

[0029] 2. The door body is opened and closed by rotating the plug connector and the socket, and the assembly process is simpler and faster. The reduction of assembly steps and the simplification of the assembly process significantly improve production efficiency and reduce production costs;

[0030] 3. The design of the first clearance groove and the second limiting hole, combined with the clamping of the limiting member, effectively limits the rotation angle of the first connecting member relative to the second connecting member. This design ensures the stability and reliability of the door during opening and closing, and avoids the door body being damaged or unable to close normally due to excessive or small rotation angles;

[0031] 4. The first connecting member and the second connecting member have a streamlined structural design, which reduces the space required for the pivot door to be opened and closed, so that the pivot door can be used flexibly in a limited space, thereby broadening the application range of the pivot door.

Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] In order to facilitate the understanding of the embodiments of the present utility model, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present utility model.

[0041] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] Embodiment 1 of the present utility model is referred to Figure 1-Figure 6As shown, a rotating shaft mechanism is disclosed, including a first connecting member 1 and a second connecting member 2 that can be rotatably connected to each other. Specifically, a protruding plug connector 3 is provided on one side of the first connecting member 1 facing the second connecting member 2, and a protruding plug socket 4 is provided on one side of the second connecting member 2 facing the first connecting member 1. The plug connector 3 can be rotatably connected after being inserted into the plug socket 4. In this embodiment 1, the first connecting member 1 is assembled to the door body 8, and the second connecting member 2 is assembled to the door frame 7; of course, the first connecting member 1 can also be installed on the door frame 7, and the second connecting member 2 is installed on the door body 8, which is not specifically limited in this embodiment. The rotation effect of the rotating shaft door can be achieved by arranging the first connecting member 1 and the second connecting member 2 that are rotatably connected on both the upper and lower sides of the door body 8. Preferably, the first connecting member 1 and the plug connector 3 are integrally formed, and the second connecting member 2 and the plug socket 4 are integrally formed, which reduces the seams between parts and potential assembly problems, improves the stability and reliability of the entire connection structure, and shortens the production cycle, improves production efficiency, and reduces production costs. In other embodiments, the connection method between the first connector 1 and the plug connector 3, and the connection method between the second connector 2 and the plug socket 4 is not specifically limited.

[0044] In order to prevent the door body 8 from sliding up and down and derailing after the first connecting member 1 and the second connecting member 2 are installed, a first clearance groove 311 is provided on one side of the plug connector 3, and a second limiting hole 411 is provided on one side of the connector socket 4 corresponding to the first clearance groove 311. The second limiting hole 411 is penetrated by a limiting member 5 engaged with the first clearance groove 311, which can effectively limit the rotation angle of the first connecting member 1 relative to the second connecting member 2, while ensuring the stability and reliability of the door during opening and closing, and preventing the door body 8 from moving up and down.

[0045] In other embodiments, the positions of the socket 4 and the plug connector 3 can also be interchanged, that is, the first connector 1 is provided with a protruding socket 4 on the side facing the second connector 2, and the second connector 2 is provided with a protruding plug connector 3 on the side facing the first connector 1, the first connector 1 is assembled to the door body 8, and the second connector 2 is assembled to the door frame 7; this arrangement significantly simplifies the structure of the hinge mechanism, which not only reduces the manufacturing cost but also improves the assembly efficiency.

[0046] In the present embodiment 1, the first connector 1 includes an assembly portion 11 and a bending portion 12, the plug connector 3 is arranged on the assembly portion 11, and the assembly portion 11 is also provided with an assembly hole 111, which can be connected to the door body 8 through the assembly hole 111 by screws or other fasteners, and the number of the assembly holes 111 is preferably two, which can prevent the assembly portion 11 from twisting; the bending portion 12 is bent to the side away from the plug connector 3, and the bending portion 12 is vertically connected to the assembly portion 11, so that the assembly portion 11 is in contact with the ground or top surface of the door body 8, and the bending portion 12 is in contact with the side of the door body 8, which is helpful for the rapid positioning effect before the fastener, and can adapt to different door frame 7 and door body 8 installation environments, and increase the convenience and adaptability of installation. In other embodiments, when the second connector 2 is assembled with the door body 8, the bending portion 12 is arranged on the second connector 2.

[0047] In order to further improve the connection stability between the plug connector 3 and the socket 4, in the present embodiment 1, the plug connector 3 includes a shaft portion 31 and an abutment platform 32, the socket 4 is a cylindrical tube having a cylindrical groove 41, the shaft portion 31 is used to be inserted into the cylindrical groove 41 of the socket 4, the abutment platform 32 is located between the shaft portion 31 and the first connector 1, and the positive projection area of ​​the abutment platform 32 on the first connector 1 is larger than the positive projection area of ​​the shaft portion 31 on the first connector 1, the abutment platform 32 can enable the hinge door to maintain stable support for the door body 8 when opening and closing, and at the same time, the larger abutment platform 32 can more effectively transfer the weight of the door body 8 and the force during opening and closing to the socket 4, which helps to optimize the force distribution and reduce the concentration of local stress. The second limiting hole 411 is connected to the cylindrical groove 41, and the inner diameter of the cylindrical groove 41 is larger than the diameter of the shaft portion 31. This ensures that the rotating shaft portion 31 has enough space when rotating in the cylindrical groove 41 without being subjected to excessive friction or resistance, thereby ensuring that the door body 8 is stable and smooth during the opening and closing process.

[0048] Optionally, in some embodiments, in order to further reduce the friction between the abutment platform 32 and the shaft portion 31, a chamfer 6 is provided at the connection between the abutment platform 32 and the first connecting member 1, which can reduce the wear between the two and extend the service life of the shaft mechanism; optionally, a chamfer 6 is provided at the end of the shaft portion 31, which can help the shaft portion 31 to quickly and accurately position the socket 4, thereby guiding the smooth insertion of the shaft portion 31 during the assembly process, thereby improving the assembly success rate and ease of use.

[0049] In order to better control the rotation angle of the door body 8, in this embodiment 1, the first give way groove 311 is arranged on the side of the shaft portion 31, and the direct projection of the first give way groove 311 on the first connecting member 1 is fan-shaped, and the central angle range of the first give way groove 311 is 90°-270°. It should be noted that the range of the central angle of the circle can be adjusted according to actual conditions. For example, when the size of the limit member 5 is large, the range of the central angle of the first give way groove 311 is too small, such as 90°, which may cause the limit member 5 to be unable to rotate after installation. Therefore, the actual rotation angle of the door body 8 is usually greater than the angle of the central angle. When the door body 8 rotates, the angle range of the fan-shaped edges on both sides of the first give way groove 311 contacting the limit member 5 is the actual rotation range of the door body 8. In this embodiment 1, the actual rotation range of the door body 8 is 150°. Therefore, the range of the central angle of the first give way groove 311 is controlled within the range of 150°-270° according to the size of the limit member 5. This setting provides a flexible door body 8 rotation angle limitation function, which can be adjusted according to specific usage scenarios and needs to meet different safety and space utilization requirements.

[0050] In some embodiments, in order to improve the limiting stability of the limiting member 5, an abutment surface 312 axially opposite to the second limiting hole 411 is provided in the first giving way groove 311, and the abutment surface 312 is used to abut against the limiting member 5. Thus, when the limiting member 5 passes through the second limiting hole 411 and abuts against the abutment surface 312 in the first giving way groove 311, the rotation angle of the door body 8 will be limited; at the same time, the abutment surface 312 provides a surface that stably contacts the limiting member 5, ensuring that when the door body 8 rotates to a specific angle, the limiting member 5 can stay stably in this position to prevent the door body 8 from rotating accidentally.

[0051] The utility model also relates to a pivot door, comprising a door frame 7, a door body 8 and a pivot mechanism, wherein the first connecting member 1 is fixedly connected to the door body 8, and the second connecting member 2 is fixedly connected to the door frame 7. Thus, the number of pivot parts of the pivot door can be simplified and the assembly efficiency can be improved.

[0052] In summary, the rotary shaft mechanism and rotary shaft door provided by the utility model have the following technical effects:

[0053] 1. The shaft mechanism only includes two main parts, the first connecting member 1 and the second connecting member 2, which significantly simplifies the structure of the shaft mechanism and reduces the number of parts, which not only reduces the manufacturing cost, but also reduces the assembly error caused by the large number of parts, thereby improving the product quality;

[0054] 2. The door body 8 is opened and closed by rotating the plug connector 3 and the socket 4, and the assembly process is simpler and faster. The reduction of assembly steps and the simplification of the assembly process significantly improve production efficiency and reduce production costs;

[0055] 3. The design of the first clearance groove 311 and the second limiting hole 411, combined with the clamping of the limiting member 5, effectively limits the rotation angle of the first connecting member 1 relative to the second connecting member 2. This design ensures the stability and reliability of the door during opening and closing, and avoids the situation where the door body 8 is damaged or cannot be closed normally due to excessive or small rotation angles;

[0056] 4. The first connecting member 1 and the second connecting member 2 have a streamlined structural design, which reduces the space required for the pivot door to be opened and closed, thereby allowing the pivot door to be used flexibly in a limited space and broadening the application range of the pivot door.

[0057] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
