Description

Technical Field

[0001] The utility model belongs to the technical field of door body anti - toppling, and particularly relates to an anti - toppling structure for a rotating door body. Background Technique

[0002] In the design of modern building entrances, rotating door bodies are widely used due to their elegant appearance and high - efficiency passage ability, especially in commercial places, public buildings, and high - end residential areas. However, over time and with frequent use, such door bodies face a common technical challenge - the phenomenon of door body sinking. Due to various factors such as aging of door body materials, deformation of support structures, or settlement of installation bases, the center of rotation of the door body around the door shaft gradually shifts, resulting in the sinking of the door body. When the sinking degree reaches a certain level, the original tight fit between the upper top shaft and the upper door shaft may fail, further leading to a serious risk of door body toppling, which poses a potential safety threat to passing pedestrians, not only disrupting the normal use of the building but also potentially causing safety accidents.

[0003] To address such safety hazards, the current common solution is to install an exposed metal anti - toppling chain. One end of the metal anti - toppling chain is connected to the door body frame, and the other end is connected to the door body. Although this approach increases the stability of the door body to a certain extent and avoids the occurrence of toppling accidents, it also introduces new problems. First, the exposed design of the anti - toppling chain breaks the overall aesthetic design of the door body, running counter to the simple and smooth lines and high - end visual effects pursued by modern architecture. Second, during the daily opening and closing of the door body, direct contact and collision between the anti - toppling chain and the door frame or the door body are inevitable, which not only generates unnecessary noise pollution, affecting the quiet comfort of the use environment, but also accelerates the wear of the chain body itself and its contact parts, shortening the maintenance cycle and increasing the maintenance cost.

[0004] Therefore, it is particularly urgent to develop a new anti - toppling structure that can effectively prevent the door body from toppling without affecting the aesthetics and use experience of the door body, in order to improve the overall performance and design aesthetics of the rotating door body while ensuring public safety. Content of the Utility Model

[0005] In order to solve the above - mentioned technical problems, the utility model is solved by the following technical solutions.

[0006] An anti - toppling structure for a rotating door body includes an upper door shaft fixedly assembled with the door body, an upper top shaft fixedly assembled with the upper cross - beam of the door frame, and an anti - tipping cable. The upper top shaft is rotatably assembled with the upper door shaft, and the upper top shaft and the upper door shaft are hollow for the anti - tipping cable to pass through; one end of the anti - tipping cable is fixedly assembled with the upper cross - beam, and the other end is fixedly assembled with the door body.

[0007] Preferably, the anti-tilting cable is a polyethylene fiber rope or a steel wire rope, so that the anti-tilting cable has good tensile resistance and wear resistance, ensuring that the anti-tilting cable can hold the door body after the door body sinks and prevent the door body from tipping over.

[0008] Preferably, the hollow parts of the upper top shaft and the upper door shaft are internally provided with lubricating grease or bearings to reduce the friction between the anti-tilting cable and the upper door shaft or the upper top shaft, extend the service life and reduce the noise.

[0009] Preferably, fixing seats are arranged at the positions on the upper cross beam and the door body for assembling the anti-tilting cable. A torsion spring shaft is assembled on the fixing seat, and the end of the anti-tilting cable is fixedly assembled with the torsion spring shaft. The design of the torsion spring shaft can wind up the anti-tilting cable, making the anti-tilting cable vertically straightened in the upper top shaft and the upper door shaft, and avoiding friction between the anti-tilting cable and the upper top shaft or the upper door shaft when the door body rotates normally.

[0010] Compared with the prior art, the utility model has the following beneficial effects: The problem of the door body tipping over after sinking is avoided through the design of the anti-tilting cable, further improving the safety and stability of the door body during use. Moreover, the hidden design of the anti-tilting cable is ingeniously integrated into the door body structure, which not only does not affect the full play of its functionality, but also ensures the consistency and aesthetic beauty of the door body appearance design, avoiding any interference with the appearance aesthetics.

[0018] Referring to Figure 1 and Figure 2 , an anti - toppling structure 3 for rotating a door body 1 includes an upper door shaft 5 fixedly assembled with the door body 1, an upper top shaft 4 fixedly assembled with the upper cross - beam 2 of the door frame, and an anti - tilt cable 6. The upper top shaft 4 is rotatably assembled with the upper door shaft 5, and the upper top shaft 4 and the upper door shaft 5 are hollow for the anti - tilt cable 6 to pass through; one end of the anti - tilt cable 6 is fixedly assembled with the upper cross - beam 2, and the other end is fixedly assembled with the door body 1.

[0019] To further improve the reliability of the anti - toppling structure 3, the anti - tilt cable 6 is a polyethylene fiber rope or a steel wire rope, so that the anti - tilt cable 6 has good tensile resistance and wear resistance, ensuring that the anti - tilt cable 6 can hold the door body 1 after the door body 1 sinks and prevent the door body 1 from toppling. The hollow parts of the upper top shaft 4 and the upper door shaft 5 are internally provided with lubricating grease or bearings to reduce the friction between the anti - tilt cable 6 and the upper door shaft 5 or the upper top shaft 4, extend the service life and reduce noise.

[0020] To enhance the environmental adaptability of the system, all exposed metal parts are treated with anti - corrosion, such as galvanizing or painting, to resist the possible rust problems under different climatic conditions and extend the service life of the overall structure. At the same time, the materials of the upper top shaft 4 and the upper door shaft 5 are selected as high - strength alloy steel to ensure that they can still maintain sufficient strength and stability under long - term dynamic loads, further consolidating the durability and safety of the anti - toppling structure.

[0021] In practical applications, this anti - toppling structure is not only applicable to common scenarios such as household entrance doors and garage doors in residential areas, but also its design flexibility and universality enable it to be easily integrated into industrial warehouse gates and gates of large commercial facilities, providing a reliable and efficient solution for the safety of various types of doors. Especially for those door bodies that need to be frequently opened and closed and bear a large weight, this structure significantly enhances the stability of the door by effectively dispersing the risk brought by the offset of the door body's center of gravity, reduces damage and safety hazards caused by accidents, and improves the user experience and the overall safety level of the place.

[0022] In addition, fixing seats 7 are provided at the positions on the upper cross beam 2 and the door body 1 for assembling the anti-tilting cable 6. A torsion spring shaft 8 is assembled on the fixing seat 7, and the end of the anti-tilting cable 6 is fixedly assembled with the torsion spring shaft 8. The design of the torsion spring shaft 8 can wind up the anti-tilting cable 6, so that the anti-tilting cable 6 located in the upper top shaft 4 and the upper door shaft 5 remains in a vertically tensioned state, effectively preventing friction between the anti-tilting cable 6 and the upper top shaft 4 or the upper door shaft 5 during the normal rotation operation of the door body 1. More importantly, in the abnormal situation where the center of gravity of the door body 1 moves downward and the upper door shaft 5 is disengaged from the upper top shaft 4, the torsion spring shaft can gently release the tension of the anti-tilting cable 6, and cleverly manage the energy release in this way, thereby avoiding the risk of breakage of the anti-tilting cable 6 caused by excessive instantaneous force, and significantly improving the safety redundancy of the anti-tipping structure 3 and the reliability of long-term operation.

[0023] Compared with the prior art, the utility model has the following beneficial effects: The problem of tipping after the door body 1 sinks is avoided through the design of the anti-tilting cable 6, further improving the safety and stability of the use of the door body 1. Moreover, the hidden design of the anti-tilting cable 6 is cleverly integrated into the structure of the door body 1, which not only does not affect the full play of its functionality, but also ensures the consistency and aesthetic beauty of the appearance design of the door body, avoiding any interference with the appearance aesthetics.

[0024] The protection scope of the utility model includes but is not limited to the above embodiments. The protection scope of the utility model is subject to the claims, and any substitutions, deformations, and improvements that are easily conceivable by those skilled in the art to this technology fall within the protection scope of the utility model.
