[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The present invention provides a double-strip silent door with a begonia corner, which has:

[0048] Door leaf 2, see Figure 3 As shown, the door leaf 2 is composed of a keel support, a wood-plastic shell layer 203 and a sound insulation layer 204 .

[0049] The wood-plastic shell layer 203 is covered on the keel support, and the sound insulation layer 204 is filled between the keel support and the wood-plastic shell layer 203 .

[0050] Door frame 1, reference Figure 1 and Figure 4 As shown, the door frame 1 includes a door frame 101 arranged in the door opening, and the side of the door leaf 2 is movably connected to one side of the door frame 101 through a hinge, and a door stop structure is arranged on the other side of the door frame 101, and the door stop structure can fit with the side of the door leaf 2 away from the hinge.

[0051] Since the main body of the door leaf 2 is supported by wood and hollow square steel keels, the overall mass of the door leaf 2 is reduced, and more space for the sound insulation layer 204 is provided. A sound insulation layer is arranged inside the door leaf 2 and filled with sound-absorbing cotton, thereby improving the sound insulation effect of the door leaf 2. The door leaf 2 is composed of a variety of media, and sound waves consume more energy to conduct in different media, thereby obtaining a better sound insulation effect.

[0052] In this implementation, refer to Figure 2 and Figure 3 As shown, the door stop structure includes two door stops 102, which are glued and fixed, and a crabapple angle style is formed on the sides of the two door stops 102. Compared with the straight door leaf 2 connected to the door frame 1, the crabapple angle connection increases the release area between the door leaf 2 and the door frame 1, thereby making the door frame 1 and the door leaf 2 tightly connected, so that the sound insulation effect when the door leaf 2 and the door frame 1 are closed can be further enhanced from the closing method of the door leaf 2 and the door frame 1.

[0053] In this embodiment, a fixing groove is opened on the side of the door frame 101, and a positioning strip is connected to the door stop 102, and the width of the positioning strip is equivalent to the width of the fixing groove.

[0054] In this embodiment, refer to Figure 4 As shown, a rubber strip groove is provided on the side of the door stop 102 close to the door leaf 2, and an anti-collision strip 103 is connected in the rubber strip groove.

[0055] Among them, the anti-collision strip 103 is a hollow rubber strip, which can not only buffer the impact between the door leaf 2 and the door frame 1, but also after the door leaf 2 and the door frame 1 are completely closed, the hollow anti-collision strip 103 is deformed and completely fits with the side of the door leaf 2 and the door frame 1, thereby further enhancing the tightness of the closure between the door leaf 2 and the door frame 1.

[0056] In this embodiment, refer to Figure 2 As shown, notches are provided on the upper side and the left and right sides of the door leaf 2. By driving the door leaf 2 to rotate, the side faces of the door leaf 2 and the notches respectively abut against the anti-collision strips 103 on the two door stops 102.

[0057] In this embodiment, the keel support includes a square steel keel 201 and a solid wood keel 202 .

[0058] The square steel keel 201 includes two square steel tubes arranged transversely and two square steel tubes arranged longitudinally, and the solid wood keel 202 includes a solid wood board arranged along the side of the square steel tube and the inner wall of the wood-plastic shell 203.

[0059] The wood-plastic shell layer 203 is a laminate of 24LVL board and 18mm wood-plastic board.

[0060] Since the door leaf 2 is made of hard material, in order to facilitate the assembly between the door leaf 2 and the door frame 1, after the installation, there is a certain gap between the door leaf 2 and the ground. In actual use, the dust on the ground will pass through the bottom of the door leaf 2. In addition, due to the existence of the gap between the bottom of the door leaf 2 and the ground, the door leaf 2's ability to block noise on the ground will be greatly reduced. Therefore, we propose the following solution to solve the above problem:

[0061] In this embodiment, refer to Figure 5 As shown, a dustproof component 3 is provided at the bottom of the door leaf 2, and the dustproof component 3 is used to reduce the distance between the door leaf 2 and the ground, prevent dust from passing through the bottom of the door leaf, and hinder the propagation of noise on the ground.

[0062] In order to achieve the above-mentioned purpose of leaving no gap between the bottom of the door leaf 2 and the ground bracket, in this embodiment, refer to Figure 6 and Figure 7 As shown, the dustproof component 3 includes a placement groove 301 opened at the bottom of the door leaf 2, and a first airbag 302 is installed in the placement groove 301. One side of the first airbag 302 extends to below the bottom of the door leaf 2, and the elastic property of the first airbag 302 can be used to make the bottom of the door leaf 2 fit with the ground, thereby achieving the purpose of dustproofing, and will not affect the rotation of the door leaf 2.

[0063] However, in actual use, during the frequent rotation of the door leaf 2, the first airbag 302 always rubs against the ground. After the first airbag 302 is worn, there will still be a gap between the door leaf 2 and the ground, and the friction between the first airbag 302 and the ground is too large, which will not only make it more difficult to rotate the door leaf 2, but also reduce the service life of the first airbag 302. To this end, we propose the following solution to solve the above problem:

[0064] Reference Figure 5 and Figure 6 As shown, in the present embodiment, a driving member 4 is further provided on the door leaf 2, and the driving member 4 is used to inflate or suck air into the first airbag 302, and as the door leaf 2 rotates, when the door leaf 2 and the door frame 1 are closed, the driving member 4 inflates the first airbag 302, and the first airbag 302 expands and contacts the ground, thereby achieving the purpose of dust prevention and sound insulation.

[0065] When the door leaf 2 is separated from the door frame 1, the driving member 4 inhales air into the first airbag 302, and the first airbag 302 shrinks and is stored in the placement groove 301. When the door leaf 2 is opened, it is usually not needed for the purpose of sound insulation. Therefore, it does not matter if there is a gap between the door leaf 2 and the ground. When the door leaf 2 is separated from the door frame 1, the first airbag 302 does not contact the ground. When the door leaf 2 rotates, it saves effort and does not cause wear to the first airbag 302, thereby increasing the service life of the first airbag 302.

[0066] In order to achieve accurate inflation and suction of the first airbag 302 by the driving member 4, refer to Figure 5 and Figure 6 As shown, in this embodiment, the driving member 4 includes a recessed groove 401 opened on the side surface of the door leaf 2 away from the hinge, a second airbag 402 is arranged in the recessed groove 401, and a plurality of permanent magnet blocks 405 are arranged along the length direction of the side surface of the door frame 1 close to the second airbag 402.

[0067] A ferromagnetic sheet 403 that can magnetically attract the permanent magnet block 405 is arranged inside the second airbag 402 along its length direction, and the ferromagnetic sheet 403 divides the inside of the second airbag 402 into a driving area and a circulation area. The driving area is located on one side close to the door frame 1, and the driving area is connected to the first airbag 302 through a connecting pipe 404.

[0068] When the door leaf 2 rotates and closes with the door frame 1, the second airbag 402 is directly opposite to the permanent magnet block 405, and the distance between the second airbag 402 and the permanent magnet block 405 is short. Under the magnetic attraction between the permanent magnet block 405 and the ferromagnetic sheet 403, the ferromagnetic sheet 403 compresses the driving area and deforms the second airbag 402. At the same time, the internal gas of the driving area enters the first airbag 302 through the connecting pipe 404, so that the first airbag 302 expands and contacts the ground, thereby achieving the purpose of sealing the bottom of the door leaf 2 with the ground when the door leaf 2 is closed with the door frame 1.

[0069] When the door leaf 2 rotates and separates from the door frame 1, the distance between the permanent magnet block 405 and the ferromagnetic sheet 403 increases, and the magnetic attraction between the permanent magnet block 405 and the ferromagnetic sheet 403 weakens. The door leaf 2 recovers under the elastic force of the second airbag 402 and the first airbag 302, and the gas inside the first airbag 302 flows back into the second airbag 402. The first airbag 302 recovers and separates from the ground, so that the user can turn the door leaf 2 with less effort and reduce the wear between the first airbag 302 and the ground.

[0070] Furthermore, a low-density liquid such as alcohol is filled between the driving area and the first airbag 302 , thereby improving the transmission efficiency between the driving area and the first airbag 302 .

[0071] In this embodiment, a vent hole is provided on the second airbag 402 to connect the circulation area with the outside, so that the air pressure in the circulation area is always the same as the outside air pressure, avoiding the air pressure in the circulation area from hindering the movement of the ferromagnetic sheet 403.

[0072] The side surfaces of the first airbag 302 and the second airbag 402 are both designed to be corrugated, so that the first airbag 302 and the second airbag 402 can be expanded and contracted along the corrugation direction.

[0073] A production process of a double-strip silent door with a begonia corner, comprising the following steps:

[0074] S1, determine the height, width and thickness of the door leaf 2, and determine the keel cutting and frame size of the door leaf 2 according to the size of the door leaf 2;

[0075] S2. Select 24LVL board and 18mm wood-plastic board to press as keel, and make horizontal and vertical keel brackets according to the size of door leaf 2, and reserve horizontal and vertical square steel pipes between the keels, insert square wood blocks into the square steel pipes and fix them between the keels with a nail gun;

[0076] S3, a waterproof and moisture-proof layer is provided on the outer side of the wood-plastic shell layer 203, and a LVL board layer is provided on the inner side;

[0077] S4, use the wood veneer to glue and press it with the keel bracket, fill the keel with sound insulation cotton, and press it for 4 hours;

[0078] S5, cutting and edge-sealing the pressed door leaf 2 according to actual needs;
