Description

Technical Field

[0001] This utility model relates to the field of home decoration technology, and in particular to a highly earthquake-resistant entrance door. Background Technology

[0002] In recent years, with the acceleration of urbanization and the frequent occurrence of earthquakes, the limitations of traditional front doors in terms of earthquake resistance and security have become increasingly apparent.

[0003] To ensure the normal opening and closing of front doors, a gap is usually left between the bottom of the door and the ground, resulting in insufficient longitudinal support. When faced with an earthquake, insufficient support in the outer door frame can cause deformation, making the door impossible to open. In an earthquake, given enough time to escape, one might be trapped in a dangerous situation because the door cannot be opened. Utility Model Content

[0004] This utility model discloses a high-strength earthquake-resistant entrance door, which aims to solve the technical problem that when faced with an earthquake, the supporting force of the outer door frame is insufficient, which will cause the door frame to deform and directly prevent the entrance door from being opened. In the event of an earthquake, if there is enough time to escape, the entrance door may be unable to be opened, which may lead to a dangerous situation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A highly earthquake-resistant entrance door, including an outer frame, and also including:

[0007] The internal support mechanism, which is filled inside the outer frame, is used to provide internal support to the outer frame and also to provide a buffering effect.

[0008] The bottom support mechanism is located inside the outer frame and at the bottom of the outer frame. It is used to seal the bottom space and provide seismic support.

[0009] The observation mechanism, which runs through the outer frame, is used to observe the environment outside the door;

[0010] The bottom support mechanism includes:

[0011] The supporting frame is fixedly connected to the inner wall of one side of the outer frame;

[0012] The hydraulic rod is fixedly connected to the inner wall of the top of the support frame;

[0013] A horizontal plate is fixedly connected to the output end of the hydraulic rod;

[0014] The bottom support mechanism also includes:

[0015] The sealing gasket is fixedly connected to the bottom end of the horizontal plate. The bottom end of the outer frame has an open structure, and the sealing gasket passes through the opening.

[0016] The hydraulic rod is used to move the sealing gasket downwards to seal the bottom space;

[0017] The bottom support mechanism also includes:

[0018] A through slot is provided through one side of the inner wall of the outer frame and is located on one side of the supporting frame;

[0019] The door is connected to the inner wall of the through groove by a hinge, and the door and the outer wall of the outer frame are both fixedly installed with a latch.

[0020] The vibration sensor is fixedly installed on the inner wall of one side of the support frame to monitor vibration.

[0021] With a bottom support mechanism, vibration sensors monitor external vibrations in real time. When a high vibration level is detected, the pressure on the ground is gradually increased. This prevents the door frame from being squeezed and deformed during an earthquake, thus ensuring the door can open and close normally and providing protection for escaping during an earthquake. At the same time, the sealing gasket also acts as a buffer.

[0022] In a preferred embodiment, the internal support mechanism includes:

[0023] A honeycomb-shaped support frame, fixedly connected inside the outer frame, is made of stainless steel and is used to provide internal support;

[0024] The filling material, made of silicone sponge, is used to fill the spaces between the honeycomb support frames. It provides sound insulation, heat insulation, and cushioning.

[0025] By incorporating an internal support mechanism, the honeycomb support frame provides stable support while significantly reducing the overall weight of the door. The silicone sponge filling provides sound and heat insulation while also absorbing longitudinal vibration energy generated by earthquakes, thus acting as a buffer and optimizing the overall earthquake resistance of the door.

[0026] In a preferred embodiment, the observation mechanism includes:

[0027] The mounting slot is installed through the outer frame, and a supporting shell is fixedly connected inside the mounting slot;

[0028] An observation hole is provided through the inner wall of one side of the supporting housing;

[0029] The decorative peephole is fixedly attached to the outer wall of the supporting shell on the same side, serving a deceptive purpose;

[0030] The observation device also includes:

[0031] A pinhole camera is fixedly connected to the bottom inner wall of the support housing, with its shooting end located inside the observation hole;

[0032] The monitor is fixedly connected to the inner wall of one side of the support housing and is connected to the pinhole camera via a wire.

[0033] With an observation mechanism, the panoramic view outside the door captured by the pinhole camera can be directly seen by turning on the monitor. In addition, the decorative peephole can confuse bad guys outside the door and improve home security.

[0034] As described above, a highly earthquake-resistant entrance door includes an outer frame and further includes: an inner support mechanism, filled within the outer frame, for providing internal support and cushioning; a bottom support mechanism, located within and at the bottom of the outer frame, for sealing the bottom space and providing earthquake-resistant support; and an observation mechanism, extending through the outer frame for observing the external environment. This highly earthquake-resistant entrance door provides the technical effect of strengthening the overall support of the door during an earthquake and preventing door frame deformation from affecting the normal opening and closing of the door.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0041] The present invention discloses a high-strength earthquake-resistant entrance door, which is mainly used in home decoration scenarios.

[0042] Reference Figure 1 and Figure 2 A highly earthquake-resistant entrance door, including an outer frame 1, and also including:

[0043] The inner support mechanism 4 is filled inside the outer frame 1 to provide internal support for the outer frame 1 and to provide a buffering effect at the same time.

[0044] The bottom support mechanism 3 is installed inside the outer frame 1 and located at the bottom of the outer frame 1. It is used to seal the bottom space and provide seismic support.

[0045] The observation mechanism 2 is installed throughout the outer frame 1 and is used to observe the environment outside the door.

[0046] Reference Figure 2 and Figure 3 In a preferred embodiment, the bottom support mechanism 3 includes:

[0047] The support frame 301 is fixedly connected to the inner wall of one side of the outer frame 1;

[0048] Hydraulic rod 302 is fixedly connected to the inner wall of the top end of support frame 301;

[0049] The horizontal plate 304 is fixedly connected to the output end of the hydraulic rod 302.

[0050] Reference Figure 2 and Figure 3 In a preferred embodiment, the bottom support mechanism 3 further includes:

[0051] The sealing gasket 305 is fixedly connected to the bottom end of the horizontal plate 304. The bottom end of the outer frame 1 is an open structure, and the sealing gasket 305 passes through the opening.

[0052] The hydraulic rod 302 is used to move the sealing gasket 305 downward to seal the bottom space.

[0053] Reference Figure 3 In a preferred embodiment, the bottom support mechanism 3 further includes:

[0054] The through slot 306 is provided through one side of the inner wall of the outer frame 1 and is located on one side of the supporting frame 301;

[0055] The sealing door 307 is connected to the inner wall of the through groove 306 by a hinge, and the sealing door 307 and the outer wall of the outer frame 1 are both fixedly installed with a latch 308.

[0056] Vibration sensor 303 is fixedly installed on the inner wall of one side of the support frame 301 to monitor vibration. Vibration sensor 303 is used to monitor external vibration in real time. When a high vibration level is detected, it is determined to be an earthquake. At this time, the hydraulic rod 302 squeezes the sealing gasket 305 to gradually increase the pressure on the ground. Together with the outer frame 1, it provides support and can prevent the door frame from being squeezed and deformed during an earthquake, thus preventing the door from opening and closing normally and providing protection for escaping during an earthquake. At the same time, the sealing gasket 305 can also play a buffering role. In daily life, when the sealing gasket 305 is located inside the outer frame 1, it can play a sound insulation role. At the same time, the protruding part can block the gap between the bottom of the door and the bottom of the door frame to prevent insects from entering.

[0057] Reference Figure 2 In a preferred embodiment, the inner support mechanism 4 includes:

[0058] The honeycomb support frame 401 is fixedly connected to the outer frame 1. It is made of stainless steel and is used to provide internal support.

[0059] The filler 402, which is filled between the honeycomb support frame 401, is made of silicone sponge and can play a role in sound insulation, heat insulation and buffering. The honeycomb support frame 401, based on its shape and material, can provide stable support while also greatly reducing the overall weight of the door. The silicone sponge filling, as a high-polymer damping material, can absorb the longitudinal vibration energy generated by earthquakes while providing sound insulation and heat insulation, thus playing a buffering role and optimizing the overall earthquake resistance of the door.

[0060] Reference Figures 2-4 In a preferred embodiment, the observation mechanism 2 includes:

[0061] The mounting slot 204 is provided through the outer frame 1, and the support shell 201 is fixedly connected inside the mounting slot 204;

[0062] An observation hole 207 is provided through the inner wall of one side of the support housing 201;

[0063] The decorative peephole 202 is fixedly connected to the outer wall of the supporting housing 201 on the same side, serving a deceptive purpose.

[0064] Reference Figure 3 and Figure 4 In a preferred embodiment, the observation mechanism 2 further includes:

[0065] The pinhole camera 206 is fixedly connected to the bottom inner wall of the support housing 201, and its shooting end is located inside the observation hole 207;

[0066] The monitor 203 is fixedly connected to the inner wall of one side of the support housing 201 and is connected to the pinhole camera 206 via the wire 205. By turning on the monitor 203, one can directly see the panoramic view outside the door captured by the pinhole camera 206. Compared with the traditional peephole, this method can better determine whether the external environment is safe. In addition, the decorative peephole 202 can confuse bad people outside the door and prevent them from discovering the existence of the observation hole 207. Even if they cover the decorative peephole 202 with their hands, it will not obstruct the observation hole 207, thus improving home security.

[0067] Working principle: The vibration sensor 303 is used to monitor external vibrations in real time. When a high vibration level is detected, it is determined to be an earthquake. At this time, the hydraulic rod 302 squeezes the sealing gasket 305, gradually increasing the pressure on the ground. Together with the outer frame 1, it provides support and can prevent the door frame from being squeezed and deformed during an earthquake, thus ensuring the normal opening and closing of the door and providing protection for escape during an earthquake. At the same time, the sealing gasket 305 can also play a buffering role. In normal operation, when the sealing gasket 305 is located inside the outer frame 1, it can play a sound insulation role. At the same time, the protruding part can block the gap between the bottom of the door and the bottom of the door frame to prevent insects from entering.

[0068] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
