[0053] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0054] Please refer to Figure 1 and Figure 2 This application discloses an indoor security door 100, comprising:
[0055] First decorative panel 11 facing one side;
[0056] Fireproof board 12 is attached to the first decorative panel 11;
[0057] A first metal plate 13 is attached to the fireproof board 12;
[0058] Cut-resistant metal mesh composite panel 14;
[0059] The second decorative panel 16 faces the other side.
[0060] An interior security door 100 is a type of door used inside a building. It is typically used in homes, hotel rooms, and offices.
[0061] The first decorative panel 11 faces one side, for example, towards the outside. Typically, for living comfort, the first decorative panel 11 can be made of wood veneer. Of course, under specific requirements, composite materials that mimic the appearance of wood can also be used. The surface of the first decorative panel 11 can exhibit wood grain or other textures.
[0062] Fireproof board 12 is bonded to the first decorative board 11. Fireproof board 12 can be made of materials such as fireproof cotton for heat insulation.
[0063] A first metal plate 13 is attached to the fireproof plate 12. The first metal plate 13 is a material used to provide the required mechanical properties such as stiffness, strength, and impact resistance. The first metal plate 13 can be made of steel or hard alloy material.
[0064] Cut-resistant metal mesh composite sheet 14 is used to prevent cutting. It typically has good elasticity and toughness.
[0065] In one specific embodiment provided in this application, the cut-resistant metal mesh composite panel 14 includes:
[0066] Cut-resistant metal mesh;
[0067] A frame that fits snugly against cut-resistant metal mesh;
[0068] The filler that fills the skeleton.
[0069] Cut-resistant metal mesh is a three-dimensional mesh structure made of metal. The metal mesh has good elasticity and toughness, allowing it to spring back when cut and making it difficult to cut. At the same time, the metal material is relatively wear-resistant, effectively preventing cutting. Cut-resistant metal mesh can be made of manganese steel.
[0070] The frame is fitted with a cut-resistant metal mesh. The frame can be made of steel to enhance its impact resistance.
[0071] The skeleton can be filled with appropriate fillers. These fillers can be formulated as needed, such as according to requirements for high temperature resistance, corrosion resistance, and impact load resistance. Specifically, fillers can include concrete, foaming agents and similar adhesives, steel balls, cinders, perlite, asbestos, etc.
[0072] In one embodiment provided in this application, a cut-resistant metal mesh and a frame are stacked together. Filler is placed inside the frame.
[0073] In another embodiment, the cut-resistant metal mesh can be fitted within the frame. Filler is placed between the cut-resistant metal mesh and the frame.
[0074] The second decorative panel 16 faces the opposite side, for example, towards the interior. Typically, for living comfort, the second decorative panel 16 can be made of wood veneer. Of course, under specific requirements, composite materials that mimic the appearance of wood can also be used. The surface of the second decorative panel 16 can exhibit wood grain or other textures.
[0075] Since the interior security door 100 is composed of a layered structure consisting of a first decorative panel 11, a fireproof panel 12, a first metal panel 13, a cut-resistant metal mesh composite panel 14, and a second decorative panel 16, the first decorative panel 11 and the second decorative panel 16 face outwards and inwards towards the user, respectively, thus maintaining the appearance of the interior door in the prior art. The fireproof panel 12, the first metal panel 13, and the cut-resistant metal mesh composite panel 14 mainly provide fireproof and heat insulation, impact resistance, and other properties, which can improve the security performance of the interior security door 100.
[0076] Furthermore, in another embodiment provided in this application, a second metal plate 15 is also provided between the cut-resistant metal mesh composite plate 14 and the second decorative plate 16 facing the other side.
[0077] The second metal plate 15 is a material used to provide the required mechanical properties such as stiffness, strength, and impact resistance. The second metal plate 15 can be made of steel or hard alloy material. The second metal plate 15 further enhances the anti-vandalism capability of the interior security door 100 in the inward direction.
[0078] Please refer to Figure 3 Furthermore, in another embodiment provided in this application, the indoor security door 100 is also provided with a periscope peephole structure 17.
[0079] The periscope peephole can prevent damage to the interior security door 100 along a straight line, thereby improving the security of the interior security door 100.
[0080] Please refer to Figures 4 to 6Furthermore, in another embodiment provided in this application, the bottom of the indoor safety door 100 is provided with a protruding baffle 18 to prevent fire and smoke.
[0081] Because a certain gap needs to be left between the interior safety door 100 and the ground to allow the interior safety door 100 to pivot, a protruding baffle 18 is provided at the bottom of the interior safety door 100 to improve its fire resistance. When the protruding baffle 18 extends, it can prevent smoke and dust from entering the room through the gap between the ground and the interior safety door 100, thus improving safety performance.
[0082] Please refer to Figure 5 and Figure 6 Furthermore, in another embodiment provided in this application, the extendable stop bar 18 is manually or automatically controlled.
[0083] Figure 5 This is a diagram showing the state of the extended stop bar 18 when it is retracted. Figure 6 The diagram shows the state when the extendable baffle 18 is extended. When the extendable baffle 18 retracts, a gap appears between the indoor safety door 100 and the ground, facilitating the rotation of the indoor safety door 100. When the extendable baffle 18 is extended, the gap between the indoor safety door 100 and the ground is blocked, preventing smoke and dust from entering the room.
[0084] Furthermore, in another embodiment provided in this application, the driving structure of the protruding baffle 18 is a worm gear structure.
[0085] Because the worm gear structure has a high reduction ratio, it can prevent damage to the indoor safety door 100 from the protruding baffle 18, thus improving safety.
[0086] Furthermore, in another embodiment provided in this application, a protective shell is provided between the first decorative panel 11 and the second decorative panel 16 of the indoor security door 100, which includes a fireproof plate 12, a first metal plate 13, and a cut-resistant metal mesh composite plate 14.
[0087] The protective shell surrounds the fireproof board 12, the first metal plate 13, and the cut-resistant metal mesh composite panel 14. In this way, when the first decorative panel 11 is damaged, the protective shell can protect the fireproof board 12, the first metal plate 13, and the cut-resistant metal mesh composite panel 14 as a whole, thereby improving the anti-vandalism performance of the indoor security door 100.
[0088] Furthermore, in another embodiment provided in this application, the indoor security door 100 has a lock mounting portion, and the mounting portion is provided with an anti-drill plate 21.
[0089] The mounting part of the lock is equipped with an anti-drill plate 21, which can prevent damage to the indoor security door 100 from the mounting part of the lock, thereby improving the anti-vandalism performance of the indoor security door 100.
[0090] Furthermore, in another embodiment provided in this application, the indoor security door 100 also has:
[0091] Metal hinges for pivoting doors installed indoors;
[0092] A fake hinge that looks exactly like a metal hinge is used to allow the wire harness to pass through.
[0093] The dummy hinges have the same shape as the metal hinges, which can improve the overall aesthetics of the interior security door 100, and also make it convenient for wire harnesses to pass through them, resulting in a better overall appearance.
[0094] Please refer to Figure 7 Furthermore, in another embodiment provided in this application, an indoor security door 100 includes:
[0095] First decorative panel 11 facing one side;
[0096] A first metal plate 13 is attached to the first decorative panel;
[0097] Fireproof board 12 that is attached to the first decorative panel;
[0098] Cut-resistant metal mesh composite panel 14;
[0099] The second decorative panel 16 faces the other side.
[0100] The difference between this embodiment and the previously provided embodiment lies in the order in which the layered structure of the first metal plate 13 and the fireproof plate 12 is arranged.
