The positioning mechanism 6 can fix the position of the fire door body 2 so that the fire door body 2 can remain in a closed state. At the same time, the fire door body 2 can be opened directly by stepping on the positioning mechanism 6.

[0025] Example 2

[0026] Reference Figure 2-4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, the positioning mechanism 6 includes a slot 601, which is opened on the left side of the back side of the baffle 5. The lower end of the front side of the fire door body 2 is fixedly connected with an insert ring 602. The front end of the insert ring 602 extends to the inner cavity of the slot 601 and is detachably connected to the inner cavity of the slot 601.

[0028] A receiving groove 603 is provided in the inner cavity of the baffle 5 and located at the lower end of the slot 601. The inner cavity of the receiving groove 603 is movably connected with a positioning column 604. A positioning groove 605 is provided at the top of the inner cavity of the slot 601. The top of the positioning column 604 extends to the inner cavity of the positioning groove 605 and engages with the inner cavity of the positioning groove 605.

[0029] A placement slot 606 is provided in the inner cavity of the baffle 5 and located at the upper end of the slot 601, and a pressure column 607 is movably connected to the inner cavity of the placement slot 606, and a fixing plate 608 is fixedly connected to the bottom of the pressure column 607. A connecting slot 609 is provided between the accommodating slot 603 and the placement slot 606, and a connecting rope 610 is movably connected to the inner cavity of the connecting slot 609, one end of the connecting rope 610 is fixedly connected to the positioning column 604, and the other end of the connecting rope 610 is fixedly connected to the fixing plate 608. A return spring 611 is fixedly connected to the bottom of the inner cavity of the accommodating slot 603 and the placement slot 606, and the top of the lower end return spring 611 is fixedly connected to the positioning column 604, and the top of the upper end return spring 611 is fixedly connected to the pressure column 607.

[0030] like Figure 2-4 As shown, pressing down on the pressure column 607 can cooperate with the fixing plate 608, the connecting rope 610 and the return spring 611 to adjust the position of the positioning column 604. At this time, the plug ring 602 is moved to the inside of the slot 601. After the movement is completed, the pressure column 607 is released, and the plug ring 602 can be fixed inside the slot 601. At this time, the positioning column 604 will be inserted into the inside of the plug ring 602 to position the fire door body 2.

[0031] Example 3

[0032] Reference Figure 2 and 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0033] In this embodiment, a fixing groove 7 is opened on the right side of the back side of the baffle 5, and the inner cavity of the fixing groove 7 is movably connected to a rotating plate 8 through a rotating shaft. A compression spring 9 is fixedly connected to the back side of the rotating plate 8, and the rear end of the compression spring 9 is fixedly connected to the inner wall of the fixing groove 7.

[0034] The inner cavity of the connecting groove 609 is provided with guide wheels 10 , and the number of the guide wheels 10 is five. The connecting rope 610 is slidably connected to the surface of the guide wheels 10 .

[0035] like Figure 2 and 4 As shown, the restoring force of the compression spring 9 can drive the rotating plate 8 to reset, so that the reset rotating plate 8 can push the fire door body 2 backwards to automatically open it. The guide wheel 10 is used to support and guide the connecting rope 610, and at the same time can reduce the friction it is subjected to.

[0036] When in use, the smoke situation on the other side can be observed through the fireproof glass 3. The baffle 5 is used to block the gap between the fire door body 2 and the ground to prevent smoke from diffusing through the gap at the bottom. When the fire door body 2 needs to be opened, just press the pressure column 607 downward with your foot. The pressure column 607 can cooperate with the fixing plate 608, the connecting rope 610 and the reset spring 611 to adjust the position of the positioning column 604, so that the positioning column 604 is moved out from the inside of the plug ring 602. At this time, under the action of the reset elastic force of the compression spring 9, the rotating plate 8 pops out from the inside of the fixed groove 7. At the same time, the rotating plate 8 can directly push open the fire door body 2.
