DETAILED DESCRIPTION

[0026] As described in the background art, for example, the above-mentioned revolving door does not have an anti-pinch function. Once a person or an object is pinched, a lot of time will be wasted in rescue, and it is easy to cause a blockage in the entry and exit of people, posing a safety hazard.

[0027] In order to solve this technical problem, the utility model provides a revolving door with an anti-pinch function, which is used for people entering and exiting public places such as hotels;

[0028] It includes a fixed door frame 1, a rotating shaft 2 is provided at the center of the inner side of the fixed door frame 1, three partition door leaves 3 are fixed in an array outside the rotating shaft 2, and an anti-pinch component is provided at the end of each partition door leaf 3 away from the rotating shaft 2;

[0029] Each anti-pinch component includes a hollow door leaf 4, and a hollow door leaf 4 is fixed to the end of each partition door leaf 3 away from the rotating shaft 2. Both sides of the inner side of the hollow door leaf 4 are provided with mounting slides 8, and three positioning guide bolts 10 are fixed to the end of each mounting slide 8 away from the partition door leaf 3. An arc-shaped door leaf 11 is slidingly connected between the three positioning guide bolts 10, and a second spring 12 is sleeved on the outer side of each positioning guide bolt 10, one end of the second spring 12 is fixed to the arc-shaped door leaf 11, and the other end of the second spring 12 is fixed to the mounting slide 8, and the side of the arc-shaped door leaf 11 close to the hollow door leaf 4 is in contact with the inner side of the hollow door leaf 4.

[0030] The revolving door provided by the utility model has a door leaf with an anti-pinch function. Through the overall structural coordination design, whether the rotating shaft 2 in the revolving door rotates in the forward or reverse direction, the revolving door can facilitate the displacement of the curved door leaf 11 through the buffer structure between the positioning guide bolt 10, the curved door leaf 11, and the second spring 12, so that people or objects can be separated from the clamped position, thereby realizing the anti-pinch function.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] Example 1:

[0034] Please refer to Figure 1-4A revolving door with an anti-pinch function for door leaves comprises a fixed door frame 1, a rotating shaft 2 is provided at the center of the inner side of the fixed door frame 1, three partition door leaves 3 are fixed in an array on the outer side of the rotating shaft 2, a hollow door leaf 4 is fixed to the end of each partition door leaf 3 away from the rotating shaft 2, a carrying slide 8 is provided on both sides of the inner side of the hollow door leaf 4, three positioning guide bolts 10 are fixed to the end of each carrying slide 8 away from the partition door leaf 3, and an arc-shaped door leaf 11 is slidably connected between the three positioning guide bolts 10;

[0035] In order to facilitate the displacement of the curved door leaf 11 and to facilitate its reset after displacement, a second spring 12 is sleeved on the outer side of each positioning guide bolt 10. One end of the second spring 12 is fixed to the curved door leaf 11, and the other end of the second spring 12 is fixed to the carrying slide 8. The side of the curved door leaf 11 close to the hollow door leaf 4 is in contact with the inner side of the hollow door leaf 4. Therefore, no matter whether the rotating shaft 2 rotates forward or reverse, the anti-pinch function can be achieved by pushing the curved door leaf 11 to cause it to displace;

[0036] In order to further facilitate the displacement of the curved door leaf 11 toward the inner side of the hollow door leaf 4, so that people or objects can escape from the clamped position from more angles when they are clamped, further improving safety, an inner partition 5 is fixed at the center of the inner side of each hollow door leaf 4, and two curved guide posts 6 are fixed on both sides of each inner partition 5. The carrying slide 8 is located on the outer side of the curved guide post 6 and is slidably connected to the curved guide post 6. The outer side of each curved guide post 6 is sleeved with a first spring 9, one end of the first spring 9 is fixed to the carrying slide 8, and the other end of the first spring 9 is fixed to the hollow door leaf 4;

[0037] In order to limit the sliding of the carrying slide 8 and prevent the carrying slide 8 from detaching from the outer side of the curved guide column 6, a limiting outer plate 7 is fixed on both sides of each hollow door leaf 4, and the carrying slide 8 is in contact with the limiting outer plate 7. When the hollow door leaf 4 and the curved door leaf 11 are blocked against the fixed door frame 1 by the rotation of the rotating shaft 2, in order to avoid a gap between the curved door leaf 11 and the fixed door frame 1, a buffer rubber pad 13 is fixed on the side of each curved door leaf 11 away from the hollow door leaf 4, and the outer side of the buffer rubber pad 13 is in contact with the inner side of the fixed door frame 1;

[0038] When the rotating shaft 2 rotates forward or backward, if a person or an object is caught between the fixed door frame 1 and the curved door leaf 11, the curved door leaf 11 is pushed and guided by the positioning guide bolt 10 to move the curved door leaf 11 toward the carrying slide 8, and the second spring 12 is squeezed to expand the gap between the curved door leaf 11 and the fixed door frame 1, thereby facilitating the person or object to escape from the trapped position. After the person or object escapes from the trapped position, the elastic force of the second spring 12 is used to facilitate the curved door leaf 11 to return to its original position.

[0039] Furthermore, while pushing the curved door leaf 11 to move it toward the direction of the carrying slide 8, it is also possible to pull the curved door leaf 11 to drive the carrying slide 8 to move toward the direction of the inner partition 5 through the guidance of the curved guide column 6, as shown in FIG. Figure 4 As shown, the gap is further expanded effectively, so that people or objects can escape from the clamped area from more angles, further improving safety, and the soft properties of the flexible material of the buffer pad 13 can achieve an anti-pinch function;

[0040] Example 2:

[0041] The difference between this embodiment and the above embodiment 1 is only the structure of the anti-pinch component. Figure 5 The anti-pinch assembly of this embodiment includes an aluminum profile door leaf 14. The end of each partition door leaf 3 away from the rotating shaft 2 is fixed with an aluminum profile door leaf 14. The end of the aluminum profile door leaf 14 away from the partition door leaf 3 is provided with a brush fixing groove, and a sealing brush 15 is provided inside the brush fixing groove. The end of the aluminum profile door leaf 14 away from the partition door leaf 3 is also fixed with a fixed channel steel 16. An EPDM rubber strip 17 is provided on the inner side of the fixed channel steel 16 and on the outer side of the aluminum profile door leaf 14. An extrusion sensor 18 is installed inside the EPDM rubber strip 17. The extrusion sensor 18 and the rotating shaft 2 are both connected to the external control module.

[0042] The EPDM rubber strip 17 is used to conveniently prevent human limbs from entering the gap. Even if they accidentally enter the gap, the squeezing sensor 18 is set. When the squeezing sensor 18 is squeezed by external force, the rotation of the rotating shaft 2 is automatically stopped, protecting the human body from being pinched and effectively reducing the damage to the human body.
