Description

Technical Field

[0001] The utility model belongs to the field of door body structures, in particular to a steel sliding door. Background Art

[0002] In the prior art, steel sliding doors are a common type of doors and windows, widely used in various buildings and facilities. Traditional steel sliding doors usually adopt a simple hinged structure, which usually only has basic opening and closing functions and lacks intelligence and adaptability. However, with the advancement of science and technology and the improvement of people's quality of life, higher requirements are also put forward for the functionality and intelligence of doors and windows.

[0003] Traditional steel sliding doors usually use a fixed connection method in the hinge structure, which cannot achieve adaptive adjustment of the door body. When the door body is subjected to external force or used for a long time, it may become loose or worn, resulting in unstable position and movement of the door body, affecting the use effect. In addition, traditional hinge structures usually lack intelligent sensing functions, and cannot detect the position and movement of the door body in real time, and cannot achieve remote monitoring and control.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0027] In the embodiment of the utility model, this case provides a steel sliding door, including a door frame 100 at the left and right ends and a hinge structure 200 connecting the two; the hinge structure 200 includes a hollow shell 210, two connecting pieces 220, two gears 230, a limit unit 240 and a sensing control module 250; the two connecting pieces 220 are located at the two ends of the bottom of the shell 210, and are respectively connected to the two door frames 100. The two gears 230 are in the shell 210, and the two gears 230 are meshed with each other. Both ends of the bottom of the shell 210 are provided with a hollow central groove 280, and a connecting column 260 passes through the connecting piece 220, the central groove 280, and the central end of the gear 230 from bottom to top, and the three rotate coaxially. The outer end of the central groove 280 is also provided with a surrounding arc groove 290, and a row of positioning posts 270 sequentially connects the connecting piece 220, the arc groove 290 and the gear 230 from bottom to top. Under the force transmission of the door frame 100, the positioning posts 270 move around the arc groove 290. The limiting unit 240 is connected to the two positioning posts 270 to reset the state of the two gears 230. The induction control module 250 is connected to the gear 230 to detect the position and movement state of the door body.

[0028] Specifically, the design consisting of the housing 210, the connecting piece 220, the gear 230, and the limiting unit 240 is relatively simple, easy to manufacture and install. The gear 230 is used to drive, which increases the flexibility and safety of the door frame 100 rotating around the linkage hinge structure. When the door frame 100 is forced to swing, the connecting column 260 is used as a fulcrum to transmit the transmission to the row column 270 to move around the arc groove 290, that is, the door frame 100 can swing with the row column 270, and the two doors can be rotated to different angles. The specific different angles depend on the angle of the arc groove 290. In this patent, an arc angle of 180° is preferred. The user can realize the switch regardless of whether the door frame 100 is pushed or pulled forward or backward. And by introducing the induction control module 250, the position and movement state of the door body can be detected in real time, which improves the convenience and safety of use.

[0029] In another embodiment of the utility model, the highest end of the travel column 270 is higher than the gear 230. The limiting unit 240 includes a spring 241 and a support rod 242. The two ends of the support rod 242 are respectively inserted into the travel columns 270 on both sides. The front and rear ends of the support rod 242 are provided with protruding ends 243 extending outward to limit the support rod 242 from being separated from the travel column 270. The spring 241 is sleeved on the outer side of the support rod 242, and the two ends of the spring 241 sleeve are respectively sleeved on the two travel columns 270. Specifically, the highest end of the travel column 270 is higher than the gear 230, and the spring 241 is fixed on the two travel columns 270. The door frame 100 is forced to swing and the gear 230 is transmitted to rotate. Since the two ends of the support rod 242 are connected to the travel columns 270 at both ends, the travel column 270 will make the support rod 242 slide on the travel column 270 when doing circular motion, and will automatically reset under the influence of the spring 241. The flexibility and safety of the sliding door rotation are increased.

[0030] In another embodiment of the utility model, a connecting piece 300 is further provided between the gear 230 and the inner side wall of the housing 210, and the connecting piece 300 and the bottom of the housing 210 are provided with a central groove 280 and an arc groove 290 at the same position. The function of the connecting piece 300 is to increase the stability of the arc groove 290, disperse the force points, and enhance the durability of the housing 210.

[0031] In another embodiment of the utility model, the sensing control module 250 includes an infrared sensing layer 251 and a transmission recording module 252. The infrared sensing layer 251 is a circular structure, which is arranged around the outer side of the arc groove 290 to sense the circumference of the arc groove 290 crossed by the travel column 270. When the travel column 270 moves on the arc groove 290, the infrared sensing layer 251 relies on light sensing to feedback the movement distance, which is accurate and reliable. The transmission recording module 252 is connected to the infrared sensing layer 251 to transmit and record information, increase modularity and intelligence, and extend the life of the hinge structure 200.

[0032] In another embodiment of the utility model, a dustproof protective cover 400 is provided at the upper end of the shell 210 to prevent dust from entering the interior of the hinge structure 200 over a long period of time and interfering with normal operation.

[0033] In another embodiment of the utility model, the two door frames 100 are made of stainless steel material.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
