specific Embodiment approach 1
[0035] like Figure 1-14As shown, a fire door includes door frame 1, door 2, door shaft 201, distribution port I202, cavity 3, descending port I301, distribution port II302, sliding plate 4, descending port II401 and portable fire extinguisher 5, One side of the door 2 is hingedly connected with the door frame 1, the inner end surface of the door 2 is fixedly connected with a cavity 3, the door 2 is provided with a distribution port I202, and the end surface connected with the door 2 on the cavity 3 is provided with a distribution port. The communication port Ⅱ302, the distribution port Ⅰ202 is in communication with the distribution port Ⅱ302, the lower surface of the cavity 3 is provided with a descending port Ⅰ301, and the sliding plate 4 is slidably connected in the distribution port Ⅰ202 and the distribution port Ⅱ302, and the descending port Ⅱ401 is set on On the sliding plate 4, a rod-shaped member is fixedly connected to the upper end of the portable fire extinguisher 5...
specific Embodiment approach 2
[0037] like Figure 1-14 As shown, the fire door also includes a contact plate 403, a sliding opening 404, a safety sheet 405 and a push rod 11. The contact plate 403 is fixedly connected to the rear end of the sliding plate 4, and the end surface of the contact plate 403 is provided with a fireproof cloth. The sliding port 404 is arranged on the right end of the contact plate 403, the safety sheet 405 is fixedly connected to the contact plate 403 and is located in the sliding port 404, and one end of the push rod 11 is stuck in the space surrounded by the sliding port 404 and the safety sheet 405, and the ejector rod 11 The other end is against the door 2. The safety sheet 405 is made of plastic material with a thickness of preferably 2mm. Its structure is a raised narrow side at the upper and lower ends. The narrow side is fixed to the contact plate 403 by hot-melt bonding. Both ends of the ejector rod 11 are provided with insulating materials, and the slippery end of the e...
specific Embodiment approach 3
[0039] like Figure 1-14 As shown, the fire door also includes a convex portion 303, a round rod 406 and a compression spring I 407. The convex portion 303 is affixed to the outer end of the cavity 3, the round rod 406 is affixed to the left side of the contact plate 403, and the round rod The front end of 406 is provided with a limiting block, and the round rod 406 is covered with a compression spring I407, and the round rod 406 is slidably connected in the convex part 303, and the convex part 303 is located between the limiting block and the compression spring I407. The combination of the limiting block and the push rod 11 can keep the front end face of the sliding plate 4 and the front end face of the door 2 overlapped to produce a certain sealing effect, and then play anti-theft or certain smoke-proof and fire-proof functions. When the contact plate 403 is pushed, the spring is compressed I407 plays a certain buffering and shock-absorbing function, prevents the emergency s...
