[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0026] Embodiment 1:
[0027] Please combine Figure 1-4 A waterproof and fireproof sealed door of this embodiment includes a door frame 1, which is fixedly connected to the ground. A sealed door body 2 is hinged on the door frame 1 through a hinge. A waterproof layer 201 and a fireproof layer 202 are arranged inside the sealed door body 2. The waterproof layer 201 is an asphalt roll material, and the fireproof layer 202 is a silicon calcium fireproof board, which can increase the waterproof and fireproof effect of the sealed door body 2. A sealing strip is fixedly connected to the edge of the sealed door body 2, which can increase the sealing effect of the sealed door body 2 after closing. A fixed handle 3 is fixedly connected to the other side of the sealed door body 2.
[0028] The anti-return closing component is used to prevent the sealed door body 2 from closing automatically. The anti-return closing component includes a movable handle 101 arranged on one side of the sealed door body 2. Two sets of cross bars 102 are symmetrically fixedly connected to the movable handle 101, and the cross bars 102 are slidably connected to the sealed door body 2. A spring 103 is sleeved on the outer side of the cross bar 102, and one end of the spring 103 is in contact with the sealed door body 2. A connecting frame 104 is fixedly connected to the movable handle 101, and a vertical rod 105 is movably connected to one side of the sealed door body 2. A connecting rod 106 is symmetrically hinged between the vertical rod 105 and the connecting frame 104 through a hinge. 5 is movably connected with a ball 107 at the bottom, and the ball 107 is in contact with the ground. A slot 108 is provided on the ground. A limit plate 109 is provided at the end of the cross bar 102, and the limit plate 109 abuts against the other end of the spring 103, which can prevent the cross bar 102 from being separated from the sealing door body 2. A screw hole is provided on the limit plate 109, and a thread is provided on the end of the cross bar 102. The limit plate 109 is threadedly connected to the cross bar 102, which is convenient for disassembly and replacement of the spring 103 to prevent fatigue due to long-term use. The size of the slot 108 matches the cross-sectional size of the vertical rod 105.
[0029] The implementation principle of a waterproof and fireproof sealing door in the embodiment of the present application is: when opening, the movable handle 101 is pushed. Since the ball 107 is in contact with the ground at this time, the movable handle 101 will not be pushed alone. Therefore, when a thrust is applied to the movable handle 101, the sealing door body 2 will be opened, and during the rotation of the sealing door body 2, the ball 107 will roll together on the ground. When the sealing door body 2 is fully opened, the vertical rod 105 will be just aligned with the slot 108. At this time, by utilizing the sliding cooperation between the cross bar 102 and the sealing door body 2, the hinged action between the vertical rod 105 and the connecting frame 104 and the connecting rod 106, and the elastic action of the spring 103 itself, the vertical rod 105 will be automatically inserted into the slot 108, thereby achieving the purpose of fixing the sealing door body 2 to prevent it from automatically closing.
[0030] When closing, pull the movable handle 101. Due to the cooperation between the vertical rod 105 and the slot 108, the movable handle 101 will be pulled outward. When the movable handle 101 is pulled outward, the vertical rod 105 will also rise together. When the vertical rod 105 is completely out of the slot 108, the sealed door body 2 will be pulled together for easy closing.
[0031] Embodiment 2:
[0032] Based on the embodiment 1, the present embodiment is further improved in that: a guide frame 110 is fixedly connected to the sealing door body 2 and the guide frame 110 is slidably connected to the vertical rod 105 , which can play a certain guiding role in the vertical movement of the vertical rod 105 .
[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
