Description

Technical Field

[0001] This utility model relates to the field of door technology, and more specifically, to a double-layer fireproof glass door. Background Technology

[0002] Glass doors are a rather special type of door. Firstly, their thickness is insufficient to classify them as solid doors, and they are not considered irregularly shaped doors. In fact, they are a special type of door. Glass doors are made of either tempered glass or ordinary float glass, and are generally constructed using glass with a thickness of 12 millimeters (mm). Tempered glass is both sturdy and safe.

[0003] For example, a fireproof glass door with publication number CN218542055U includes a door frame and a fireproof glass door leaf, wherein: the door frame is mounted on the cavity wall, and the fireproof glass door leaf is symmetrically installed inside the door frame; the door frame also has a middle frame, and the fireproof glass door leaf is located on two opposite sides of the middle frame; an outward hinge is provided between the door frame and the fireproof glass door leaf, and the fireproof glass door leaf can rotate on the door frame through the hinge point of the outward hinge; fireproof glass is provided inside the middle frame.

[0004] However, in the event of a fire, the fireproof glass doors mentioned above will allow smoke to enter the room through the gap between the two glass doors, thus endangering indoor safety. Utility Model Content

[0005] This utility model provides a double-layer fireproof glass door, which can effectively improve the smoke prevention effect of the glass door and prevent medicines from entering the room through the gap between the two glass doors.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a double-layer fireproof glass door, including a door frame, characterized in that two glass doors are rotatably connected inside the door frame, and grooves are provided on the opposite surfaces of the two glass doors. An expansion strip is fixedly connected in each of the mounting grooves. When a fire occurs, the expansion strip expands, and a stop block is provided in the groove. When the expansion strip expands, the groove becomes smaller and the stop block abuts against the side wall of the glass door.

[0007] A further preferred embodiment of this utility model is that the cross-section of the groove is triangular, and two expansion strips are provided on the inner sidewall of each groove.

[0008] A further preferred embodiment of this invention is that the abutment is elastic.

[0009] A further preferred embodiment of this utility model is as follows: a closing layer is fixedly connected to the opening of each groove. The closing layer is elastic, and when the expansion strip expands, the abutment slides and the closing layer deforms.

[0010] A further preferred embodiment of this invention is that both the closing layer and the abutment are made of silicone rubber.

[0011] A further preferred embodiment of this utility model is as follows: one of the glass panels has two grooves on its side wall, and the other glass door has one groove, with the grooves between the two glass doors staggered.

[0012] A further preferred embodiment of this invention is that the glass door has a vacuum layer inside.

[0013] This utility model includes a door frame with two glass doors rotatably connected inside. Grooves are provided on the opposite surfaces of the two glass doors, and an expansion strip is fixedly connected to each groove. In the event of a fire, the expansion strip expands, and a stop block is provided within the groove. When the expansion strip expands, the groove shrinks, and the stop block abuts against the side wall of the glass door. Therefore, in the event of a fire, the expansion strip expands due to high temperature, reducing the space within the groove. The expansion strip pushes the stop block against the side wall of the glass door, effectively reducing the gap between the two glass doors in the event of a fire, thus preventing smoke from the fire from spreading into the room and endangering the lives of people inside. This design effectively improves the sealing effect of the glass door in the event of a fire. Attached Figure Description

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0019] like Figure 1 and Figure 2 As shown, a double-layer fireproof glass door includes a door frame 1, with two glass doors 2 rotatably connected inside the door frame 1. The glass doors 2 are provided with a vacuum layer 3. Therefore, in the event of a fire, the glass doors 2 with the vacuum layer 3 can block gas heat conduction, which can significantly reduce heat transfer and thus effectively increase the temperature of the glass doors 2, making it easier to open during subsequent rescue.

[0020] like Figures 2-5 As shown, grooves 7 are provided on the opposite surfaces of the two glass doors 2. An expansion strip 6 is fixedly connected in each groove. When a fire occurs, the expansion strip 6 expands. A stop block 4 is provided in the groove 7. When the expansion strip 6 expands, the groove 7 becomes smaller and the stop block 4 abuts against the side wall of the glass door 2.

[0021] like Figures 2-5 As shown, when a fire occurs, the high temperature generated by the fire causes the expansion strip 6 to expand, which reduces the space in the groove 7. At this time, pushed by the expansion strip 6, the block 4 gradually slides outward until it comes into contact with the side wall of the adjacent jasmine. At this time, the jasmine can reduce the gap 8 between the two glass doors 2 when a fire occurs, thereby effectively reducing the spread of smoke and preventing smoke from entering the room and endangering the safety of the people inside.

[0022] like Figures 2-5 As shown, the cross-section of the groove 7 is triangular, and two expansion strips 6 are provided on the inner sidewall of each groove 7. Since the groove 7 is triangular, it is easy to install two expansion strips 6. Furthermore, by setting two expansion strips 6, they can expand rapidly in the event of a fire, thereby pushing the abutment block 4 to abut against the opposite glass door 2. This design enables the glass door 2 to quickly close the gap 8 in the event of a fire, thereby blocking smoke and effectively improving efficiency.

[0023] like Figures 2-5 As shown, the abutment 4 is elastic, so when the abutment 4 comes into contact with the opposite side wall of the glass door 2, the abutment 4 deforms, thereby improving the sealing effect and reducing the possibility of smoke leakage.

[0024] like Figures 2-5As shown, a closing layer 5 is fixedly connected to the opening of each groove 7. The closing layer 5 is elastic. When the expansion strip 6 expands, the block 4 slides and the closing layer 5 deforms. By setting the closing layer 5, the block 4 is restricted within the groove 7, thereby effectively preventing the block 4 from separating from the glass door 2 after sliding out of the groove 7. This design restricts the range of motion of the groove 7. As the block 4 slides, the closing piece also deforms, which can effectively prevent the closing piece from affecting the use of the block 4.

[0025] like Figures 2-5 As shown, both the closing layer 5 and the stop block 4 are made of silicone rubber. This material has good high temperature resistance and can maintain elasticity in high temperature environments, thereby ensuring the normal use of the closing layer and the stop block 4 in the future.

[0026] like Figures 2-5 As shown, one glass door 2 has two grooves 7 on its side wall, and the other glass door 2 has one groove 7. The grooves 7 between the two glass doors 2 are staggered. When the abutment 4 slides out of the groove 7, the two abutment 4 also abut against each other, thereby further improving the smoke prevention effect of the glass door 2.

[0027] The present invention provides a double-layer fireproof glass door. Specific examples have been used to illustrate the principle and implementation of the invention. The descriptions of these embodiments are merely for the purpose of helping to understand the invention and its core concepts. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
