Description

Technical Field

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

[0002] In the field of pivot door installation, ensuring the flatness of the door body and the ground and the uniformity of the force applied to the door body when it rotates is crucial to the service life and overall safety of the pivot mechanism. However, in the actual installation process, since the door frame may have an inclination angle in the vertical direction, or the line between the upper and lower pivots is not perpendicular to the horizontal plane, these problems often cause the door body to be uneven with the ground after installation, and the force applied to the door body is uneven when it rotates, which seriously affects the service life and overall performance of the pivot mechanism.

[0003] At present, the common method to solve the above problem is to remove the shaft mechanism after finding that the door frame is tilted or the shaft is improperly positioned, adjust the position of the door frame or the shaft to meet the installation requirements, and then fix it again. This method requires a lot of manpower and time, increases the complexity of assembly, and frequent removal and installation may cause damage to the door frame or the shaft mechanism, further reducing its service life. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the utility model provides a leveling shaft mechanism and a shaft door, which can solve the problem that the shaft mechanism needs to be removed for leveling and improve the efficiency of the shaft mechanism installation.

[0005] The technical solution adopted by the utility model to solve the problem is:

[0006] A leveling shaft mechanism includes: a limit member, on which a sliding cavity is arranged; a first shaft mounting member, which is slidably arranged in the sliding cavity; a second shaft mounting member, which is rotatably connected to the first shaft mounting member; and a fixing member, which passes through the first shaft mounting member and is fixedly connected to the limit member.

[0007] By adopting the above solution, the sliding cavity on the limiter allows the first rotating shaft mounting member to slide therein, so that the position of the first rotating shaft mounting member can be adjusted to a certain extent. Since the second rotating shaft mounting member is rotatably connected to the first rotating shaft mounting member, the position adjustment of the first rotating shaft mounting member will also indirectly affect the position of the second rotating shaft mounting member, thereby adjusting the relative position between the upper and lower rotating shafts, thereby achieving the effect of leveling the door body.

[0008] Furthermore, one of the first rotating shaft mounting member and the second rotating shaft mounting member is provided with a rotating shaft sleeve protruding outwardly, and the other is provided with a rotating part protruding outwardly, and a rotating shaft is provided between the rotating shaft sleeve and the rotating part.

[0009] By adopting the above solution, the rotating shaft between the rotating shaft sleeve and the rotating part will maintain a stable rotational connection, ensuring that the door body can rotate smoothly during the adjustment process.

[0010] Furthermore, the rotating part is provided with a cylindrical groove fixedly connected to the rotating shaft, and the rotating shaft sleeve is provided with a through hole for the rotating shaft to pass through, and the rotating shaft passes through the through hole and is connected to the cylindrical groove, so that the rotating part and the rotating shaft rotate synchronously relative to the rotating shaft sleeve.

[0011] By adopting the above scheme, the rotating part and the rotating shaft rotate synchronously relative to the rotating shaft sleeve, ensuring that the door body is evenly stressed when rotating, avoiding damage to the rotating shaft mechanism due to uneven stress, and thus increasing the service life of the rotating shaft mechanism.

[0012] Furthermore, a first waist-shaped hole for the shaft sleeve and / or the rotating part to slide and a fixing hole fixedly connected to a fixing member are provided in the sliding cavity.

[0013] By adopting the above solution, the shaft sleeve and / or the rotating part can be ensured to remain stable and smooth during the sliding process, and the relative position between the upper and lower shafts can be indirectly adjusted, thereby solving the problem of door frame tilt or improper shaft position. At the same time, the shape design of the waist-shaped hole can also reduce friction and improve the smoothness and accuracy of sliding. The main function of the fixing hole is to firmly fix the first shaft mounting member at a designated position in the sliding cavity through the fixing member, ensuring the stability of the door body after installation.

[0014] Furthermore, a clamping groove is provided on the first rotating shaft mounting member, and a clamping member partially penetrates through the first waist-shaped hole and is clamped with the clamping groove is provided on the back side of the sliding cavity.

[0015] By adopting the above scheme, the clamping connection between the clamping member and the clamping groove can make the first rotating shaft mounting member only move along the sliding cavity in the sliding cavity and cannot be separated from the sliding cavity, thereby improving the sliding stability.

[0016] Furthermore, the clamping member includes: an abutment plate, the area of ​​the abutment plate is larger than the area of ​​the first waist-shaped hole; an insert tube, the insert tube is vertically connected to the abutment plate and passes through the first waist-shaped hole; a claw, the claw is circumferentially distributed on the insert tube and protrudes from one end of the insert tube toward the clamping groove, so that the claw is clamped with the clamping groove.

[0017] By adopting the above solution, the clamping member achieves accurate positioning and stable fixation of the first rotating shaft mounting member through a simple structure, thereby limiting its movement direction and ensuring the stability of the first rotating shaft mounting member sliding along the sliding cavity.

[0018] Furthermore, the number of the clamping claws is more than two, and the number of the clamping slots is consistent with the number of the clamping claws.

[0019] By adopting the above solution, the stability of the clamping connection is improved and it is avoided that the clamping state is easily released.

[0020] Furthermore, a second waist-shaped hole is also provided on the first rotating shaft mounting member, and the fixing member can slide along the second waist-shaped hole.

[0021] By adopting the above solution, by adjusting the position of the fixing member in the second waist-shaped hole, the position of the first rotating shaft mounting member can be fine-tuned to meet different installation requirements.

[0022] Furthermore, the fixing member comprises an operating section and a connecting section, the diameter of the operating section is larger than the diameter of the connecting section, an abutting lip plate is arranged in the second waist-shaped hole, and the abutting lip plate abuts against the operating section of the fixing member.

[0023] By adopting the above solution, it is possible to prevent the fixing member from completely penetrating the second waist-shaped hole, so that the first rotating shaft mounting member can be locked to the limiting member, thereby achieving fixation of the first rotating shaft mounting member after adjusting the position.

[0024] A pivot door comprises a door frame, a door body and an adjustable pivot mechanism, wherein the limit member is fixedly connected to the door frame, and the second pivot mounting member is fixedly connected to the door body; or, the limit member is fixedly connected to the door body, and the second pivot mounting member is fixedly connected to the door frame.

[0025] By adopting the above solution, the design of the adjustable leveling shaft mechanism ensures the smooth rotation and positioning of the door body, while providing an adjustment function to adapt to different installation environments and requirements.

[0026] In summary, the adjustable leveling shaft mechanism and the shaft door provided by the utility model have the following technical effects:

[0027] 1. Improve installation efficiency and accuracy: Through the sliding cavity in the limiter and the sliding first shaft mounting member, the position of the door body can be directly adjusted to keep it level with the ground without removing the shaft mechanism. This not only avoids the tedious process of frequent dismantling and installation in traditional methods, but also improves installation accuracy and efficiency.

[0028] 2. Extend the service life of the hinge mechanism: Since the adjustable hinge mechanism can adjust the position of the door body and ensure that the door body is evenly stressed when rotating, it reduces the wear and damage of the hinge mechanism caused by uneven force and extends the service life of the hinge mechanism.

[0029] 3. Enhance overall safety: By ensuring the flatness of the door body and the ground and the uniformity of the force applied to the door body when it rotates, the adjustable pivot mechanism and pivot door can provide a more stable and safer user experience.

[0030] 4. Strong adaptability: The design of the adjustable leveling pivot mechanism enables the pivot door to adapt to different installation environments and requirements. Whether it is a tilted door frame, uneven ground or other installation problems, they can be solved by adjusting the adjustable leveling pivot mechanism, which enhances the applicability and versatility of the pivot door.
