[0021] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] See Figure 1 This utility model provides a structure for preventing the installation misalignment of fireproof mortise locks on fireproof doors, comprising:

[0023] A fireproof protective cover 2 is pre-assembled inside the fireproof door body 1. A guide steel plate 3 and a guide steel plate 4 are fixedly installed inside the fireproof protective cover 2. A guide area 5 is formed between the guide steel plate 3 and the guide steel plate 4. The fireproof protective cover 2 is parallel to the fireproof door body 1. A fireproof mortise lock body 10 is adapted to be inserted between the two guide areas 5.

[0024] With the above structure, guide steel plate 3 and guide steel plate 4 are wrapped inside the fireproof protective cover 2. When the fireproof mortise lock body 10 is installed, it is inserted into the fireproof protective cover 2 from the two guide areas 5 along the side of the door. The two guide areas 5 match the thickness of the fireproof mortise lock body 10, and the fitting gap does not exceed 2mm. The fireproof mortise lock body 10 always remains parallel to the fireproof door body 1 and will not be installed off-center or swing.

[0025] Specifically, the fire door body 1 has a side groove 6, and an adapter frame 7 is fitted inside the side groove 6. The adapter frame 7 has a socket 9. The fireproof mortise lock body 10 has a docking frame 11 fixedly installed. The docking frame 11 is adapted to the side groove 6. The docking frame 11 has a second hole 12. The adapter frame 7 has a first hole 8. The first hole 8 and the second hole 12 are fitted with fixing screws 13. The inner wall of the side groove 6 has a fixing screw groove. The screw part of the fixing screw 13 passes through the second hole 12 and the first hole 8 and is threadedly connected to the fixing screw groove.

[0026] With the above structure, the fireproof mortise lock body 10 is inserted into the fireproof door body 1 from the side. The fireproof protective cover 2 is pre-assembled inside the fireproof door body 1. The fireproof protective cover 2 is parallel to the fireproof door body 1. The fireproof mortise lock body 10 is inserted into the fireproof door body 1 along the two guide areas 5 without affecting the mating holes and structure of the fireproof door body 1. After the fireproof mortise lock body 10 is installed in place, the fixing screws 13 on the fireproof mortise lock body 10 are tightened to ensure that the fireproof mortise lock body 10 is parallel to the fireproof door body 1 without deviation. After installing other accessories of the fireproof mortise lock body 10, there will be no more problems of lock tongue jamming or lock tongue inflexibility caused by the deviation of the fireproof mortise lock body 10.

[0027] Specifically, the fireproof protective cover 2 is made of ceramic fiber, which gives it good fireproof performance.

[0028] Working principle:

[0029] S1: During the manufacturing process of the fire door body 1, a fireproof protective cover 2 is pre-assembled inside the door body. At the same time, a side groove 6 is opened on the side of the fire door body 1, and the adapter frame 7 is installed in the side groove 6. The hole 8 on the adapter frame 7 corresponds to the fixing screw groove on the inner wall of the side groove 6. The fireproof mortise lock body 10 is inserted from the side of the fire door body 1. Since the guide area 5 formed between the guide steel plate 3 and the guide steel plate 4 inside the fireproof protective cover 2 matches the thickness of the fireproof mortise lock body 10 and the fitting gap does not exceed 2mm, the fireproof mortise lock body 10 will slide along the guide area 5 during the insertion process, thereby ensuring that it is always parallel to the fire door body 1 and avoiding front and back deviation or swinging.

[0030] S2: When the fireproof mortise lock body 10 is inserted into place, the docking frame 11 on the fireproof mortise lock body 10 is adapted to the side groove 6, and the second hole 12 on the docking frame 11 is aligned with the first hole 8 on the adapting frame 7. At this time, by passing the fixing screw 13 through the second hole 12 and the first hole 8 and connecting it with the fixing screw groove on the inner wall of the side groove 6, the fireproof mortise lock body 10 is firmly fixed to the fireproof door body 1.

[0031] S3: In daily use, since the fireproof mortise lock body 10 is installed without misalignment, the bolt can extend and retract smoothly, ensuring the normal opening and closing functions of the fire door. This reduces bolt jamming or inflexibility caused by lock body misalignment, eliminating the need for frequent on-site maintenance, reducing labor costs and inconvenience. In extreme situations such as fires, the fireproof protective cover 2, made of ceramic fiber, can effectively block heat transfer and delay the spread of fire to the fireproof mortise lock body 10 due to its excellent high-temperature resistance and heat insulation properties. This provides good fire protection for the lock body, ensuring that the fire door can still maintain normal operation for a certain period of time during a fire, providing safety for personnel to escape in emergencies.

[0032] The above provides a detailed description of the structure for preventing the installation misalignment of a fireproof door lock cylinder provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
