Description

Technical Field

[0001] This utility model relates to a fire-resistant bag, belonging to the field of fireproof sealing technology. Background Technology

[0002] During the construction of electrical wires and cables, fire-resistant partitions and floors are often penetrated by the laid cables and pipes, thus forming corresponding holes and gaps. For fire safety purposes, the corresponding holes and gaps need to be fireproofed and sealed. In addition, fire-resistant bags are used in situations where the cable position is frequently changed.

[0003] For example, Chinese utility model patent CN202161716U discloses a fireproof sealing fire-retardant bag, comprising a fire-retardant bag body made of a flame-retardant fiberglass cloth bag and a flame-retardant and fire-resistant material constrained within the flame-retardant fiberglass cloth bag. The flame-retardant and fire-resistant material includes a sheet-like unexpanded vermiculite layer and an expanded perlite granular layer. The outer surface of the flame-retardant fiberglass cloth bag is coated with an anti-oxidation coating. The upper surface of the fire-retardant bag body has a recess, and several protruding ridges are evenly distributed within the recess. The lower surface of the fire-retardant bag body has a protrusion that matches the recess on the upper surface of the fire-retardant bag body, and the protrusion and the corresponding position of the protruding ridge in the recess have a matching groove. The above patent has a low thermal conductivity, good heat insulation effect, and is resistant to oil, acid, alkali and other chemicals. The mutually matching recesses, protrusions, ridges and grooves on the fire-retardant bag body form a mutually locking relationship during stacking, making stacking convenient and less prone to collapse.

[0004] The above solution has the following shortcomings in practical use: 1. Although the above-mentioned patent can make it convenient to stack using protrusions and grooves, this stacking method only relies on the cooperation of the upper and lower surfaces, which is prone to lateral collapse. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a fire-resistant bag, which aims to solve the problem that current stacking methods rely solely on the cooperation of the upper and lower surfaces, making them prone to lateral collapse.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A fire-resistant bag includes fiberglass cloth, an intumescent flame-retardant layer connected to the inner wall of the fiberglass cloth, a heat insulation layer installed on the inner side of the intumescent flame-retardant layer, multiple spherical buckles at the bottom of the fiberglass cloth, spherical grooves corresponding to the spherical buckles at the top of the fiberglass cloth, multiple spherical buckles on one side wall of the fiberglass cloth, and spherical grooves corresponding to the multiple spherical buckles on the other side wall of the fiberglass cloth. The spherical buckles and grooves in this design allow for the support of adjacent fire-resistant bags, while the spherical buckles and grooves create a lateral locking between the left and right fire-resistant bags, preventing individual fire-resistant bags from detaching during the transport of multiple fire-resistant bags.

[0007] Preferably, the spherical buckle has an interior chamber filled with multiple fire extinguishing particles, and the side wall of the spherical buckle has multiple through holes, each of which is filled with a layer of paraffin wax. In this design, when a small fire occurs in the outside, the paraffin wax layer melts, and the fire extinguishing particles are removed from the through holes, thereby actively extinguishing the small fire.

[0008] Preferably, a flame-retardant adhesive layer is provided between the glass fiber cloth and the inflatable flame-retardant layer, and the glass fiber cloth and the inflatable flame-retardant layer are connected by the flame-retardant adhesive layer.

[0009] Preferably, the heat insulation layer includes a flame-retardant fiber mixture layer, which is installed on the inner wall of the inflatable flame-retardant layer, and a heat-insulating particle layer is installed on the inner wall of the flame-retardant fiber mixture layer; in this scheme, the flame-retardant fiber mixture layer and the heat-insulating particle layer play the main heat insulation role.

[0010] Preferably, the intumescent flame-retardant layer comprises one of intumescent flame-retardant particles or intumescent flame-retardant powder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up spherical buckle one and spherical buckle two, spherical buckle one and spherical groove one can lock and fix the fireproof bags that fit together vertically, while spherical buckle two and spherical groove two can lock and fix the fireproof bags that fit together horizontally. The fireproof bags of this device have added a lateral locking structure, which solves the problem that existing fireproof bags rely only on the fit of the upper and lower surfaces and are prone to lateral collapse during transportation; and by setting fire extinguishing particles and a paraffin layer inside the spherical buckle, the fireproof bag can have an active fire extinguishing function.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 and Figure 2 This utility model provides a technical solution: A fire-retardant bag includes a fiberglass cloth 1, an intumescent flame-retardant layer 2 connected to the inner wall of the fiberglass cloth 1, a heat insulation layer 3 installed on the inner side of the intumescent flame-retardant layer 2, a plurality of spherical buckles 4 at the bottom of the fiberglass cloth 1, a spherical groove 5 corresponding to the spherical buckles 4 at the top of the fiberglass cloth 1, a plurality of spherical buckles 6 on one side wall of the fiberglass cloth 1, and a spherical groove 7 corresponding to the plurality of spherical buckles 6 on the other side wall of the fiberglass cloth 1.

[0016] Specifically, one or two layers of breathable flame-retardant lining (such as flame-retardant non-woven fabric) can be sewn inside the fiberglass cloth 1 to both prevent the leakage of powder from the expansion layer and to ensure the release of gas during expansion. This inflatable flame-retardant layer 2 is close to the outermost layer and expands first when exposed to fire, directly sealing the gaps in the fiberglass cloth 1 and providing the first barrier for the inner layer's heat insulation.

[0017] Furthermore, the interior of the spherical buckle 6 has a chamber filled with multiple fire extinguishing particles 8, and the side wall of the spherical buckle 6 has multiple through holes, each of which is filled with a layer of paraffin wax 9.

[0018] Specifically, the spherical buckle 4 and the spherical buckle 6 have the same structure. These spherical buckles also have anti-slip textures, which increase the friction between adjacent fire-resistant bags, help the locking structure resist vertical shear forces, and further reduce the risk of stacking collapse.

[0019] This application places the spherical buckle 4 at the bottom and the spherical groove 5 at the top. This design allows the spherical buckle 4 to directly transfer the weight of the upper layer to the inner wall of the spherical groove 5. As a load-bearing structure, the inner wall of the spherical groove 5 can disperse pressure through a large area of ​​contact, reducing material damage caused by excessive force at a single point. If the spherical buckle 4 is located in the recess at the top of the upper layer, it needs to bear the reverse support force from the upper layer to the lower layer during stacking. Long-term pressure can easily cause the spherical buckle 4 to shift due to material deformation in the recessed area. With the reverse arrangement, the cooperation between the spherical buckle 4 and the spherical groove 5 is closer to the load-bearing and load-bearing logic, and the structural stability is more suitable for vertical stacking scenarios.

[0020] Furthermore, a flame-retardant adhesive layer 10 is provided between the fiberglass cloth 1 and the inflatable flame-retardant layer 2, and the fiberglass cloth 1 and the inflatable flame-retardant layer 2 are connected by the flame-retardant adhesive layer 10.

[0021] Specifically, the flame-retardant adhesive layer 10 serves to fix the subsequently filled expansion layer material, preventing powder or particles from scattering, and the flame-retardant adhesive layer 10 enhances the adhesion between the fiberglass cloth 1 and the inner layer, preventing the layers from separating when exposed to fire.

[0022] Furthermore, the heat insulation layer 3 includes a flame-retardant fiber mixture layer 31, which is installed on the inner wall of the intumescent flame-retardant layer 2, and a heat-insulating particle layer 32 is installed on the inner wall of the flame-retardant fiber mixture layer 31.

[0023] Furthermore, the intumescent flame retardant layer 2 includes either intumescent flame retardant particles or intumescent flame retardant powder.

[0024] In summary, by setting up spherical buckle 4 and spherical buckle 6, spherical buckle 4 and spherical groove 5 can lock and fix the fireproof bags that fit together vertically, while spherical buckle 6 and spherical groove 7 can lock and fix the fireproof bags that fit together horizontally. The fireproof bags of this device have an added lateral locking structure, which solves the problem that existing fireproof bags rely only on the fit of the upper and lower surfaces and are prone to lateral collapse during transportation. Furthermore, by setting fire extinguishing particles 8 and a paraffin layer 9 inside the spherical buckles, the fireproof bags can have an active fire extinguishing function.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
