[0026] See Figure 1 and Figure 2 This embodiment provides a collision-resistant free-opening door, including a door leaf 1, a door frame 2, and a hinge assembly. The upper part of the door leaf 1 is connected to the hinge assembly, and the hinge assembly is installed on the door frame 2 to enable the door leaf 1 to open and close freely relative to the door frame 2. The lower part of the door leaf 1 is provided with an elastic element 3 for connecting with the door frame 2, and the elastic element 3 is used to limit the movement distance of the door leaf 1 relative to the door frame 2.

[0027] The door leaf 1 is made of a material with a certain degree of flexibility, such as door fabric or PVC, or steel as needed. The door leaf 1 is installed on the door frame 2 via a hinge assembly to achieve automatic reset after the door leaf 1 is opened. The elastic element 3 is installed in the lower middle part of the free door to allow the door leaf 1 to open to a sufficient angle while limiting its movement; the elastic material also facilitates the reset of the door leaf 1.

[0028] The free-opening door of this application achieves free opening and closing of door leaf 1 through a hinge assembly. An elastic element 3 is installed below door leaf 1, which not only limits the opening and closing of door leaf 1 but also increases the opening angle of door leaf 1, reducing contact friction with equipment such as forklifts or handcarts, thus minimizing damage to door leaf 1. Furthermore, after door leaf 1 is forced open, the elastic element 3 automatically resets door leaf 1, ensuring door closure. In addition, the hinge assembly design enables door leaf 1 to automatically reset. This utility model's anti-collision free-opening door has a simple structure, strong practicality, and is suitable for various scenarios such as cold storage, logistics warehousing, and food processing plants.

[0029] See Figure 2 In this embodiment, the hinge assembly includes a base 4 and a pivot 5. The base 4 is vertically oriented, and its upper and lower ends are respectively provided with a first connecting plate 6 and a second connecting plate 7 for rotatably connecting with the pivot 5. The length of the first connecting plate 6 is greater than the length of the second connecting plate 7, allowing the pivot 5 to be tilted relative to the base 4. The first connecting plate 6 is tilted downward relative to the base 4. The two ends of the pivot 5 are connected to through holes on the first connecting plate 6 and the second connecting plate 7, respectively, and a limiting component is provided on the pivot 5. The angle between the pivot and the first connecting plate 6 is 90-95°, causing the center of gravity of the triangular structure formed by the base 4, the pivot, and the first connecting plate 6 to be downward. When the door leaf 1, which is mounted on this triangular structure, is forced open by an external force, it can automatically reset due to this force characteristic.

[0030] In this embodiment, the rotating shaft 5 is provided with a horizontally extending mounting plate 8, which is used to connect with the door leaf 1. A reinforcing rib 13 is provided at the connection point between the mounting plate 8 and the rotating shaft 5, and the reinforcing rib 13 supports the mounting plate 8. The mounting plate 8 is made of metal and provides a certain rigidity to the door leaf 1, ensuring that the two door leaves 1 can close together. The mounting plate 8 has mounting holes, and the door leaf 1 is fixedly connected to the mounting plate 8 using bolts or other fasteners, thereby achieving a stable connection between the door leaf 1 and the hinge assembly.

[0031] In this embodiment, a sealing strip 9 is installed on the door frame 2 to form a seal with the mounting plate 8. The sealing strip 9 has a groove to accommodate the width of the mounting plate 8. The sealing strip 9 is made of an elastic material, such as rubber or silicone, and has good sealing and wear resistance. When the door leaf 1 is closed, the mounting plate 8 is tightly pressed into the groove of the sealing strip 9, effectively preventing cold air or dust from leaking through the door gaps and ensuring the door's insulation and sealing performance. At the same time, the design of the sealing strip 9 also reduces friction between the door leaf 1 and the door frame 2, extending the door's service life.

[0032] In this embodiment, the hinge assembly further includes a hinge baffle 10, which is used to install on the door frame 2, and the base 4 is used to install on the hinge baffle 10. The hinge baffle 10 has a U-shaped structure with side plates on both sides and a U-shaped groove in the middle. During installation, the U-shaped groove is engaged with the door frame 2 and fixed with screws. The design of the hinge baffle 10 enhances the stability of the hinge assembly, preventing it from shaking or falling off under force, and further improving the durability and safety of the door leaf 1.

[0033] In this embodiment, two door panels 1 are symmetrically mounted on the door frame 2. Each door panel 1 is connected to the door frame 2 via a hinge assembly, and the two door panels 1 can be magnetically attracted to each other via a magnetic connector 11 to achieve a tight closure. When it is necessary to open the door panel 1, equipment such as a forklift or handcart can directly impact the door panel 1, causing it to rotate and open around the hinge assembly under the action of external force. Due to the special design of the hinge assembly, the door panel 1 can be opened to a large angle, facilitating the passage of equipment. At the same time, the elastic element 3 below the door panel 1 limits the movement distance of the door panel 1, preventing it from being over-opened and damaged. After the door panel 1 is impacted, it can automatically reset with the elastic restoring force of the elastic element 3, without manual operation, greatly improving passage efficiency and door closure.

[0034] In this embodiment, a magnetic connector 11 is provided within the connecting edge of the two door panels 1. The magnetic connector 11 is used to connect the two door panels 1 to each other. The magnetic connector 11 is preferably a magnet or magnetic strip, which has a strong attraction force, ensuring that the two door panels 1 fit tightly together and preventing cold air or dust from leaking out from the gaps. At the same time, the design of the magnetic connector 11 also facilitates the quick opening and closing of the door panels 1, improving the ease of operation of the door.

[0035] In this embodiment, the elastic element 3 is an elastic band or spring. One end of the elastic band or spring is connected to the lower part of the door leaf 1, and the other end is connected to the door frame 2. Its elastic force supports and limits the door leaf 1. When the door leaf 1 is forced open, the elastic element 3 deforms, absorbing the impact energy. After the external force disappears, it uses its own elastic restoring force to push the door leaf 1 towards the closing direction, achieving automatic reset. This design not only improves the impact resistance of the door leaf 1 but also ensures the stability and closure of the door leaf 1 after an impact.

[0036] In this embodiment, a baffle plate 12 is also included, which is installed on the door leaf 1 and positioned on the outside of the hinge assembly. The design of the baffle plate 12 is primarily based on two considerations: firstly, the baffle plate 12 protects the hinge assembly from external environmental corrosion, such as preventing moisture and dust from entering the hinge assembly and affecting its normal operation, thereby extending the service life of the hinge assembly; secondly, the baffle plate 12 also serves an aesthetic purpose, making the overall appearance of the anti-collision swing door neater and more beautiful. The baffle plate 12 can be made of the same material as the door leaf 1 to ensure overall harmony. During installation, the baffle plate 12 is fixed to the door leaf 1 using screws or clips, ensuring a secure connection between them.

[0037] In this embodiment, a viewing window is also provided on the door leaf 1. The viewing window is preferably made of a transparent material, such as tempered glass or transparent plastic, to allow observation of the inside of the door leaf 1. The design of the viewing window enhances the practicality of the door, allowing the viewer to see the items or people behind the door without opening the door leaf 1, thus improving work efficiency and safety. Simultaneously, the viewing window can also serve as a decorative element, enhancing the overall aesthetics of the door.

[0038] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
