Description

Technical Field

[0001] The utility model relates to the technical field of plastic floors, in particular to a PVC flame-retardant plastic floor. Background Art

[0002] At present, the PVC plastic floor in the prior art generally does not have a flame retardant function. Therefore, when a fire occurs, the PVC plastic floor will become a combustion aid, thereby aggravating the spread of the fire. For this reason, we propose a PVC flame retardant plastic floor. Utility Model Content

[0003] Based on this, the purpose of the utility model is to provide a PVC flame-retardant plastic floor to solve the technical problems mentioned in the above background.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PVC flame-retardant plastic floor, comprising a plastic floor, wherein the end surface of the plastic floor is provided with a plurality of groups of recessed holes distributed at intervals, and a sealing cover is installed inside the recessed holes, a handle for assisting the movement of the sealing cover is fixed to the top of the sealing cover, an air cavity filled with a high-pressure flame retardant is provided inside the plastic floor below the recessed holes, and an inflation hole for inflating the air cavity is installed at the top of the air cavity, and a sealing membrane for sealing the air cavity is provided at the bottom of the air cavity.

[0005] By adopting the above technical solution, a large amount of flame retardant can be released when a fire occurs, thereby achieving the flame retardant performance of the plastic floor and effectively curbing the fire.

[0006] The utility model is further configured that the inner wall of the concave hole is provided with a threaded wall, and the outer wall of the sealing cover is provided with a thread, and the threaded wall is adapted to the thread of the outer wall of the sealing cover.

[0007] By adopting the above technical solution, the air cavity can be sealed.

[0008] The utility model is further configured that the sealing film is made of polyethylene material.

[0009] By adopting the above technical solution, the sealing of the air cavity can be quickly released.

[0010] The utility model is further configured that a follower plate slidably connected to the inner wall of the air cavity is also arranged inside the air cavity, and an indicator rod extending upward is fixedly connected to the top of the follower plate.

[0011] By adopting the above technical solution, the air pressure of the air cavity can be detected.

[0012] The utility model is further configured that a one-way valve is provided inside the driven plate, and the one-way valve is communicated with the inflation hole.

[0013] By adopting the above technical solution, the air supply effect to the air cavity is achieved.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] 1. The utility model provides an air cavity and a sealing film. First, after installing the plastic floor, the sealing cover is rotated by a handle so that the sealing cover moves under the action of the threaded wall until the sealing cover is completely removed. Then, a high-pressure flame retardant is injected into the air cavity through the inflation hole by an external device to complete the addition of the flame retardant. When a fire occurs, the high temperature will dissolve the sealing film, thereby causing the flame retardant in the air cavity to be ejected, which can not only prevent the plastic floor from supporting combustion, but also suppress the fire.

[0016] 2. The utility model provides a follower plate, a one-way valve and an indicator rod. The indicator rod can automatically monitor the pressure of the flame retardant in the air cavity mechanically. Specifically, when the air pressure in the air cavity becomes low, the follower plate will move downward under the action of its own gravity. After the follower plate is displaced, it will drive the indicator rod to move synchronously. After the indicator rod moves, it will remind personnel that the internal pressure of the air cavity is insufficient. Then the personnel can refill and pressurize the air cavity, thereby ensuring the injection pressure of the flame retardant, that is, ensuring the flame retardant performance.

[0021] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] A PVC flame retardant plastic floor, such as Figure 1-3As shown, it includes a plastic floor 1, and the end surface of the plastic floor 1 is provided with a plurality of groups of recessed holes 2 distributed at intervals, and a sealing cover 3 is installed inside the recessed hole 2, and a handle 4 for assisting the movement of the sealing cover 3 is fixed on the top of the sealing cover 3, and an air cavity 6 filled with a high-pressure flame retardant is provided inside the plastic floor 1 below the recessed hole 2, and an inflation hole 5 for inflating the air cavity 6 is installed at the top of the air cavity 6, and a sealing membrane 7 for sealing the air cavity 6 is provided at the bottom of the air cavity 6.

[0024] Furthermore, in this embodiment, the inner wall of the recessed hole 2 is provided with a threaded wall, and the outer wall of the sealing cover 3 is provided with a thread, and the threaded wall is adapted to the thread of the outer wall of the sealing cover 3 .

[0025] See also Figure 2 The sealing film 7 is made of polyethylene material, which is conducive to quickly releasing the seal of the air cavity 6, thereby achieving the effect of releasing the flame retardant.

[0026] See also Figure 2-3 A follower plate 8 is provided inside the air cavity 6 and is slidably connected to the inner wall of the air cavity 6, and an indicator rod 10 extending upward is fixedly connected to the top of the follower plate 8. A one-way valve 9 is provided inside the follower plate 8, and the one-way valve 9 is connected to the inflation hole 5 to realize mechanical monitoring of the air pressure in the air cavity 6, thereby ensuring the normal flame retardant function.

[0027] The working principle of the utility model is as follows: first, after installing the plastic floor 1, the sealing cover 3 is rotated by the handle 4, so that the sealing cover 3 moves under the action of the threaded wall until the sealing cover 3 is completely moved out, and then the high-pressure flame retardant is injected into the air cavity 6 through the inflation hole 5 by an external device to complete the addition of the flame retardant;

[0028] When a fire occurs, the high temperature will dissolve the sealing film 7, thereby causing the flame retardant in the air cavity 6 to be ejected, which can not only prevent the plastic floor 1 from supporting combustion, but also suppress the fire;

[0029] In addition, the indicator rod 10 can mechanically and automatically monitor the flame retardant gas pressure in the air cavity 6. Specifically, when the gas pressure in the air cavity 6 becomes low, the driven plate 8 will move downward under the action of its own gravity. After the driven plate 8 is displaced, it will drive the indicator rod 10 to move synchronously. After the indicator rod 10 moves, it will remind personnel that the internal pressure of the air cavity 6 is insufficient. Then the personnel can refill and pressurize the air cavity 6, thereby ensuring the injection pressure of the flame retardant, that is, ensuring the flame retardant performance.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
