Description

Technical Field

[0001] The utility model belongs to the field of fire door equipment, in particular to a radiation-resistant fire door with a prolonged service life. Background Art

[0002] A fire door is a door that functions as a fireproof separation and can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. In actual use, fire doors have a short service life. Frequent daily use can cause deformation of the door leaf, affecting its fireproof sealing performance. This is because there is a lack of components that increase the service life. The lack of components that increase the service life will not only lead to the above problems, but may also cause the fire door to deform if it is frequently impacted by external factors. This not only increases the cost of maintenance and replacement, but may also affect the normal function of the fire door at critical moments. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a radiation-resistant fire door with a prolonged service life, comprising: a frame 100, a fire door body 200, two groups of fire door bodies 200 are hinged inside the frame 100, the two groups of fire door bodies 200 have the same structure, the left and right surfaces of the fire door bodies 200 are symmetrically installed with a protective plate 210 and a handle 220, and the two fire door bodies 200 are symmetrically hinged inside the frame 100, and the interior of the fire door body 200 is provided with a fireproof layer 300 and a handle 220. And the shielding layer 310, the fireproof layer 300 and the shielding layer 310 are both arranged with two layers, a cavity layer 320 is arranged in the middle of the fire door body 200, and a reinforcement component 330 is installed inside the cavity layer 320. The reinforcement component 330 includes: a mounting plate 331, a reinforcement cylinder 332, a reinforcement rod 333, a spring 334 and a fixing plate 335. A reinforcement cylinder 332 is respectively installed on the left surface and the right surface of the mounting plate 331, and a spring 334 and a reinforcement rod 333 are installed inside the reinforcement cylinder 332.

[0021] See also Figures 1 to 3As the first embodiment of the utility model: the front and rear inner walls of the frame 100 are respectively hinged with a fire door body 200, a handle 220 is installed on the right side of the front fire door body 200, a handle 220 is installed on the left side of the rear fire door body 200, and a protective plate 210 is installed on the upper and lower parts of the left and right surfaces of the fire door body 200;

[0022] The four protective plates 210 have the same structure. A fireproof layer 300 is symmetrically arranged on the left and right sides of the fireproof door body 200. A fireproof plate is installed inside the fireproof layer 300. A shielding layer 310 is symmetrically arranged on the right side of the left fireproof layer 300 and on the left side of the right fireproof layer 300.

[0023] A lead plate is installed inside the shielding layer 310. The thickness of the shielding layer 310 is less than the thickness of the fireproof layer 300. A cavity layer 320 is formed between the two shielding layers 310. The thickness of the cavity layer 320 is equal to the sum of the thickness of the shielding layer 310 and the fireproof layer 300.

[0024] When in use, the left and right sides of the fire door body 200 are both installed with protective plates 210, and the cavity layer 320 inside the edge of the fire door is evenly installed with multiple reinforcement components 330. When the fire door is hit by the outside, the protective plate 210 can play a certain blocking role to prevent external factors from directly acting on the fire door body 200. At the same time, if the fire door body 200 is hit very seriously, the reinforcement rod 333 inside the fire door body 200 will be displaced by the impact, and then the spring 334 connected to it will be compressed, thereby offsetting the impact as much as possible. Part of the impact force (at this time the impact force is far greater than the force of the spring 334 to recover its deformation, so the reaction force generated by the spring 334 to recover its deformation is very small and can be ignored, and it only plays a part in the force release), the protective plate 210 can provide additional protection, so that the fire door can better resist the influence of external factors. At the same time, the internal reinforcement component 330 and the external protective plate 210 increase the overall firmness of the door. The protective plate 210 can reduce the damage and wear of the door body and reduce the frequency of maintenance and replacement, thereby increasing the service life of the fire door body 200.

[0025] See also Figures 1 to 3 As a second embodiment of the utility model: a plurality of reinforcement components 330 are evenly installed inside the cavity layer 320, and the plurality of reinforcement components 330 have the same structure, a side of the reinforcement cylinder 332 away from the mounting plate 331 is designed as a circular opening, and a spring 334 is installed at the bottom of the reinforcement cylinder 332;

[0026] A reinforcing rod 333 is movably installed inside the reinforcing cylinder 332, the bottom end of the reinforcing rod 333 is connected to the end of the spring 334 away from the reinforcing cylinder 332, and the end of the reinforcing rod 333 away from the spring 334 is integrally formed with a fixing plate 335, and the fixing plate 335 is connected to the inner wall of the cavity layer 320;

[0027] When in use, when a fire occurs outside or inside or radiation is generated, the fireproof layer 300 and the shielding layer 310 will block the radiation and flame. The setting of the fireproof layer 300 and the shielding layer 310 increases the practicality of the door. Although the fire door body 200 has a certain fireproof ability, an additional fireproof layer 300 is added inside it, so that the fireproof board inside the fireproof layer 300 and the fire door body 200 itself can effectively prevent the spread of fire and provide protection for a certain period of time. At the same time, the lead plate inside the shielding layer 310 can effectively shield radiation and protect people from radiation damage.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
