Description

Technical Field

[0001] The invention relates to the technical field of furniture, and in particular to a sealed wooden door. Background Art

[0002] The existing wooden doors are easily affected by the humid environment and deform and expand. When the wooden door is flush with the ground, it will not be able to close after a period of time due to deformation. Therefore, there will be a gap between the bottom edge of the wooden door and the ground, and there will also be a gap between the side of the wooden door and the door frame. In summer or winter, the cold or warm air generated by the air conditioner will rush out through the gap at the bottom of the door, and it will take a long time for the indoor temperature to drop or rise. Especially in the north, there will be strong winds in winter, and the wind will blow into the house through the door gap, making the temperature in the house low and making people very susceptible to cold.

[0003] After checking the prior art, I learned that the patent application number of "201611170975.4" is "sealed wooden door". The patent discloses that the side of the door body equipped with the safety tongue lock pin is the right side, and the side opposite to the right side is the left side. After closing the door, when the safety button is turned to lock the door, the safety tongue lock pin moves to the right, so that the transmission rod moves to the right, and the push plate moves to the right, increasing the pressure in the right box, so that the liquid in the right box enters the water bag through the first liquid guide tube, so that the water bag expands, the gap between the door body and the door frame is sealed, and the gap between the bottom of the door body and the ground is sealed at the same time. The force of the user turning the safety tongue lock pin is used to seal the sides of the door body, so that the air conditioner can reduce the temperature in the house in time in summer, and in winter, it can prevent wind from blowing into the house from the gap;

[0004] However, the door's anti-pry capability is not good enough, and the user's field of vision when observing the outdoors from indoors is limited. Summary of the invention

[0005] The purpose of the invention is to solve the shortcomings of the prior art that the door body has poor anti-pry ability and the user's field of vision for observing the outdoors from indoors is small, and a sealed wooden door is proposed.

[0006] In order to achieve the above-mentioned purpose, the invention adopts the following technical scheme: a sealed wooden door, comprising a door frame and a door leaf, the inner wall of the door frame is hinged to the door leaf by a hinge, the surface of the door leaf is inlaid with an observation mechanism, the interior of the door leaf is fixedly connected with an exhaust fan, the exhaust end of the exhaust fan is fixedly connected with a connecting pipe, the inner wall of the door leaf is fixedly connected to the connecting pipe, the inner wall of the connecting pipe is fixedly connected with a one-way valve, the surface of the connecting pipe is fixedly connected with a connecting pipe, the inner wall of the connecting pipe is fixedly connected with a solenoid valve, one end of the connecting pipe is fixedly connected with an exhaust pipe, the inner wall of the door leaf is fixedly connected to the exhaust pipe, a negative pressure groove is opened on the front of the door leaf, the inner wall of the negative pressure groove is provided with an exhaust port, the inner wall of the door frame is provided with a sealing groove, and the inner wall of the sealing groove is detachably connected with a sealing gasket.

[0007] Preferably, the observation mechanism includes a mounting frame, an inner wall of the mounting frame is fixedly connected to explosion-proof glass, a vacuum layer is provided on the inner wall of the mounting frame and behind the explosion-proof glass, and a single light-transmitting glass is fixedly connected to the inner wall of the mounting frame and behind the vacuum layer.

[0008] Preferably, an embedding groove is provided on the inner wall of the installation frame, and the inner wall of the embedding groove is fixedly connected to the explosion-proof glass.

[0009] Preferably, a tempered film is adhered to the surface of the explosion-proof glass, and an anti-oxidation coating is provided on the surface of the mounting frame.

[0010] Preferably, a flame retardant layer is fixedly connected to the surface of the door leaf, and the four corners of the front side of the door leaf are arranged to be rounded.

[0011] Preferably, a filter screen is embedded on the back of the door leaf, and the position of the connecting pipe is adapted to the filter screen.

[0012] Preferably, a smart lock is provided on the front of the door leaf, and a fingerprint recognition area and a password recognition area are provided on the smart lock.

[0013] Preferably, there are two air extraction ports, and both ends of the air extraction pipe are respectively connected to the two air extraction ports.

[0014] Preferably, the inner wall of the negative pressure groove is provided with a protective layer, and the position of the negative pressure groove is adapted to the sealing gasket.

[0015] Preferably, a bolt groove is provided on the surface of the sealing gasket, a fixing screw is provided on the inner wall of the bolt groove, and the fixing screw is threadably connected to the door frame.

[0016] The invention has the following beneficial effects:

[0017] Compared with the prior art, the sealed wooden door, after the door leaf is closed, the sealing gasket fits with the negative pressure groove, and the exhaust fan is started. The exhaust fan extracts the air in the negative pressure groove through the connecting pipe and the exhaust pipe, so that the negative pressure groove is in a negative pressure state, thereby fixing the door leaf inside the door frame, improving the fixing effect of the door leaf, and the fixing point is the negative pressure groove, and the connection point is not limited to the door lock and the hinge, thereby improving the anti-pry ability of the door leaf and the sealing performance after the door leaf is closed. When refrigeration or heating equipment is used indoors, air flow can be reduced and indoor thermal insulation capacity can be improved. The solenoid valve is opened, and air enters the negative pressure groove after being filtered through the filter net, contacts the negative pressure state inside the negative pressure groove, and then the door leaf is opened. After the sealing gasket is greatly worn and the sealing capacity cannot be guaranteed, the fixing screws are removed to remove the sealing gasket, and then the sealing gasket is replaced. The user observes the external situation through the observation mechanism with a wider field of view. The explosion-proof glass makes the observation mechanism not easily damaged. The vacuum layer improves the sound insulation and thermal insulation effects of the observation mechanism. The single light-transmitting glass prevents outsiders from seeing the indoor situation.
