Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision doors, in particular to a free anti-collision door. Background Art

[0002] Anti-collision free door, as the name suggests, is a door that prevents collision. It is also called two-way passage door, impact door, and anti-collision door. It is a non-electric door that can be opened in both directions through collision and can automatically close by gravity after people or objects pass through. It is also used in many explosive environments such as petrochemical, metallurgy, textile, food, bioengineering, pharmaceuticals, warehouses, aerospace engineering, and places with temperature control requirements. It operates quietly and divides the space into two different areas through anti-collision free door to block working noise, maintain a comfortable working environment, and improve environmental hygiene. Anti-collision free door has the functions of insect prevention, dust isolation, wind isolation, and odor isolation. Compared with ordinary doors, it better meets the requirements of hygiene standards and improves work efficiency. It can be opened freely in two directions by hand pushing or trolley and collision, and it will automatically close after people or objects pass through, simplifying the past series of complex actions of stopping, opening, passing, and closing.

[0003] In the use of anti-collision free doors, multiple free anti-collision doors are usually installed outside undivided warehouses or production workshops. In some cases, for the convenience of management, some doors will be specified to allow only one-way transportation, and the two-way free opening and closing setting of the free anti-collision door cannot effectively restrain the workers, which brings inconvenience to management. In order to facilitate the management of the free door and facilitate the subsequent changes in management methods to manage the restricted direction, and at the same time, the sealing strip on the outside of the door frame will be severely worn after long-term use, affecting the subsequent sealing effect. For this reason, we propose a free anti-collision door. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a free anti-collision door, including a door frame 1, the inner side of the door frame 1 is movably sleeved with two door panels 2, the rotating piece 4 is located on the outer side of the door panel 2 when in the swing state, the length of the rotating piece 4 is greater than the height of the top side of the door frame 1, and the setting of the rotating piece 4 plays a role in limiting the door panel 2. Through the setting of the rotating piece 4, the opening and closing direction of the free door can be effectively managed, which is convenient for managing the entire warehouse and facilitating the use of the equipment. At the same time, the setting of the rotating piece 4 can no longer hinder the arbitrary movement of the door panel 2 when it is fixed on the top. A support twist 3 is fixedly installed at the front and rear sides of the door frame 1 near the top side, and the width of the door panel 2 is the same as that of the door frame 1. The inner side of the rotating piece 4 and the outer side of the door frame 1 are fitted together. The setting of the supporting twist 3 can stably support the rotating piece 4, so that the rotating piece 4 can move arbitrarily around the supporting twist 3. The movable position of the door panel 2 can be stably limited by the position of the rotating piece 4, which is convenient for the use of the equipment and improves the practicality of the equipment. The outer side of the supporting twist 3 is movably sleeved with a rotating piece 4, and the movable frame 8 is located below the rotating piece 4. The top surface of the movable frame 8 fits the bottom surface of the rotating piece 4, and the total height of the movable frame 8 and the rotating piece 4 is the same as the top side height of the door frame 1. The setting of the movable frame 8 can limit the position of the rotating piece 4, and then control the opening and closing of the door panel 2 in any direction. When one side needs to be closed, the movement of the door panel 2 can be stably limited by lowering the rotating piece 4. After the movable frame 8 supports the rotating piece 4, any movement of the rotating piece 4 can be effectively avoided. The front and rear sides of the door frame 1 are fixedly installed with support rods 5 near the top side. The support rods 5 are Electromagnetic blocks 6 are fixedly connected at both ends, and a movable block 7 is movably mounted on the outer side of the support rod 5. A movable frame 8 is fixedly installed on the bottom end of the movable block 7. The electromagnetic block 6 is controlled to be powered off, and then the electromagnetic block 6 no longer locks the movable block 7. By moving the movable block 7, the movable block 7 is moved in the middle of the door frame 1 restricted by the support rod 5. When the movable block 7 moves, the movable frame 8 can be driven to move synchronously, so that the movable frame 8 no longer supports the rotating piece 4, and the rotating piece 4 will swing around the supporting twist 3, and the rotating piece 4 will swing freely to the outside of the door panel 2.

[0020] The door panel 2 has an internal movable sleeve with a connecting piece 9, a connecting sleeve 10 is fixedly connected to the outer side of the connecting piece 9, a sealing piece 11 is fixedly installed on the outer side of the connecting sleeve 10, the door panel 2 and the connecting piece 9 have internal movable sleeves with bolts 12, and nuts 13 are mounted on the outer side of the bolts 12. The setting of the connecting piece 9 can facilitate the separation of the sealing piece 11 and the door panel 2, and the connecting piece 9 and the door panel 2 can be quickly separated when in use, which facilitates the use of the equipment and improves the practicability of the equipment. At the same time, the setting of the connecting sleeve 10 can support multiple layers of sealing pieces 11 when in use to ensure stability in use.

[0021] In summary, when the free anti-collision door is in use, when it is necessary to limit the opening and closing direction of the free door, on one side of the limiting direction, the electromagnetic block 6 is controlled to be powered off, and then the electromagnetic block 6 no longer locks the movable block 7, and the movable block 7 is moved through the movable block 7, so that the movable block 7 is moved in the middle of the door frame 1 restricted by the support rod 5. When the movable block 7 moves, the movable frame 8 can be driven to move synchronously, so that the movable frame 8 no longer supports the rotating piece 4, and the rotating piece 4 will swing around the supporting twist 3. The rotating piece 4 will swing freely to the outside of the door panel 2, and then the activity range of the free door can be effectively limited. Subsequently, during use, when the outer side of the sealing piece 11 needs to be replaced after long-term wear, first separate the bolts 12 and the nuts 13, and then separate the connecting piece 9 and the connecting sleeve 10 from the sealing piece 11 and the door panel 2, replace the new sealing piece 11, and insert the connecting piece 9 into the inner side of the door panel 2, and fix the door panel 2 and the connecting piece 9 through the cooperation of the bolts 12 and the nuts 13.
