Description

Technical Field

[0001] The invention relates to the technical field of furniture, and in particular to a magnetic sound-absorbing door. Background Art

[0002] A magnetic door actually refers to a door that uses magnetism as a driving force to make the door close automatically. The main components of a magnetic door are the door and the door frame. Iron sheets and magnets are installed at the corresponding positions of the edge of the door and the door frame respectively. When the door is opened, the interaction force between the iron sheet and the magnet will cause the door to close automatically. The magnetic door uses this interaction force to achieve the effect of automatically closing the door.

[0003] After the traditional magnetic silent door is closed, the door can be tightly closed under the action of magnetic force. However, when the magnetic silent door is opened, the magnetic force will form resistance. When the door rotates, the distance between the iron sheet and the magnet will increase, and the magnetic force will become weaker. Therefore, there will be a great sense of frustration when opening the door, which may easily shock the user and reduce the user experience. In serious cases, the user may fall, posing a safety hazard. Summary of the invention

[0004] The purpose of the invention is to solve the shortcomings of the prior art that there is a great sense of frustration when opening the door, which is easy to shock the user and reduce the user's experience. In serious cases, the user may fall and there is a safety hazard. A magnetic silent door is proposed.

[0005] In order to achieve the above-mentioned purpose, the invention adopts the following technical scheme: it includes a door edge, a door body hinged on the inner wall of the door edge, and a locking mechanism, characterized in that: the inner walls of both side surfaces of the top of the door edge are inlaid with mounting sleeves, the inner walls of the mounting sleeves are fixedly connected with symmetrically distributed dampers, one end of the damper is fixedly connected with an electric auxiliary wheel, the surface of the electric auxiliary wheel extends out of the inner wall of the door edge by 0.3 to 0.7CM, the inner wall of the mounting sleeve is fixedly connected with a first spring, one end of the first spring is fixedly connected to the electric auxiliary wheel, both side surfaces of the back side of the door body are inlaid with first magnetic strips, and the exposed corners of the first magnetic strips are set as rounded corners, and the second magnetic strips are inlaid at the top corners of the back side of the door body.

[0006] Preferably, the locking mechanism comprises a fixing sleeve symmetrically embedded in the top of the door edge and a wear-resistant sleeve symmetrically embedded in the upper surface of the door body, and the position of the fixing sleeve is adapted to the wear-resistant sleeve.

[0007] Preferably, an expanding tube is fixedly connected to the inner wall of the fixing sleeve, an electromagnetic block is fixedly connected to the inner wall of the expanding tube, and a slot is provided on the lower surface of the electromagnetic block.

[0008] Preferably, the inner wall of the wear-resistant sleeve is slidably connected with a fixing rod, one end of the fixing rod is inlaid with an iron block, one end side wall of the fixing rod is fixedly connected with a sleeve, and the surface of the sleeve is fixedly connected with a push plate.

[0009] Preferably, a connecting sleeve is embedded on the surface of the door body and located below the wear-resistant sleeve, the inner wall of the connecting sleeve is slidably connected to the push plate, and a return spring in a compressed state is arranged on the inner wall of the connecting sleeve and located above the push plate.

[0010] Preferably, the first magnetic attraction strip and the second magnetic attraction strip both include a wear-resistant protective layer, the inner wall of the wear-resistant protective layer is fixedly connected to a heat insulation layer, and the inner wall of the heat insulation layer is fixedly connected to a permanent magnet.

[0011] Preferably, a matching strip is fixedly connected to the inner wall of the door edge at positions corresponding to the first magnetic strip and the second magnetic strip, and an elastic pad is fixedly connected to the surface of the matching strip.

[0012] Preferably, a mounting groove is provided on the surface of the door edge, and a front corner of the door edge is configured as a rounded corner.

[0013] Preferably, a handle is provided on the front side of the door body, and the handle is signal-connected to the locking mechanism.

[0014] Preferably, an installation area is provided on the front side of the door body, and a transparent soundproof window is fixedly connected to the inner wall of the installation area.

[0015] The invention has the following beneficial effects:

[0016] The electric auxiliary wheel can cooperate with the electric auxiliary wheel to close the door body, so that the door body can be opened easily and the electric auxiliary wheel can be turned downward to turn the door body to close.

[0017] 2. Compared with the prior art, the magnetic silent door, after the door body is closed, the slot is aligned with the iron block, the handle is pulled upward, the electromagnetic block is energized to generate magnetic force, and under the traction of the magnetic force, the iron block is pulled through the sleeve and the push plate to pull the reset spring to contract, generating elastic force, thereby reducing the moving speed of the iron block, reducing the collision force between the iron block and the electromagnetic block, and increasing the service life of the iron block and the electromagnetic block, while reducing the noise generated. Generally, the door is locked through a door lock, which only locks one position, and the door fixing effect is not good enough, and the anti-theft effect is not good.

[0018] 3. Compared with the prior art, the magnetic silent door has a first magnetic strip and a second magnetic strip close to a matching strip made of iron. The permanent magnet and the matching strip attract each other, so that the first magnetic strip and the second magnetic strip fit with the elastic pad, thereby sucking the door body. When the door is not locked, the door body is not easily opened by air flow. The heat insulation layer makes it difficult for the outside temperature to affect the permanent magnet, making it difficult for the permanent magnet to be demagnetized. The door edge is installed on the wall through the installation groove on the door edge. The transparent soundproof window uses single-light-transmitting glass. The situation outside the door can be observed through the transparent soundproof window, and the situation inside the door body cannot be observed from the outside.

[0029] Example:

[0030] Reference Figure 1-6The invention provides a magnetic silent door: it includes a door edge 1, a door body 2 hinged on the inner wall of the door edge 1 and a locking mechanism, the inner walls of both sides of the top of the door edge 1 are inlaid with mounting sleeves 3, the inner wall of the mounting sleeve 3 is fixedly connected with symmetrically distributed dampers 4, one end of the damper 4 is fixedly connected with an electric auxiliary wheel 5, the surface of the electric auxiliary wheel 5 extends out of the inner wall of the door edge 1 by 0.3 to 0.7 cm, the inner wall of the mounting sleeve 3 is fixedly connected with a first spring 6, one end of the first spring 6 is fixedly connected to the electric auxiliary wheel 5, both sides of the back of the door body 2 are inlaid with first magnetic strips 18, and the exposed corners of the first magnetic strip 18 are set as rounded corners, the top corners of the back of the door body 2 are inlaid with second magnetic strips 19, and the front of the door body 2 is provided with a handle 25. When the door body 2 is closed, the door body 2 enters the door edge 1, and when passing the electric auxiliary wheel 5, the rounded corners of the first magnetic strip 18 can better contact with the electric The auxiliary wheel 5 cooperates so that the electric auxiliary wheel 5 fits tightly against the side of the door body 2, and the electric auxiliary wheel 5 rotates and cooperates so that the resistance is small when the door body 2 is closed. In the above process, the door body 2 pushes the electric auxiliary wheel 5 toward the inside of the installation sleeve 3, and the electric auxiliary wheel 5 does not hinder the closing of the door body 2. At this time, the damper 4 generates damping to reduce the moving speed of the electric auxiliary wheel 5, and performs buffering when the door body 2 rotates quickly to reduce the force of the door body 2 colliding with the door edge 1 when closing, thereby reducing the noise generated when the door body 2 is closed. The first spring 6 is compressed to generate elastic force, so that the electric auxiliary wheel 5 can fit tightly against the door body 2. When opening the door, the handle 25 is connected to the electric auxiliary wheel 5 signal, and the handle 25 rotates downward to send an opening signal to the electric auxiliary wheel 5. The electric auxiliary wheel 5 rotates to provide auxiliary power for the rotation of the door body 2, so that the door body 2 can be opened effortlessly and is not prone to a sense of jamming.

[0031] Reference Figure 1-4The locking mechanism includes a fixed sleeve 7 symmetrically embedded in the top of the door edge 1 and a wear-resistant sleeve 12 symmetrically embedded in the upper surface of the door body 2, and the position of the fixed sleeve 7 is adapted to the wear-resistant sleeve 12, the inner wall of the fixed sleeve 7 is fixedly connected with a flared tube 8, the inner wall of the flared tube 8 is fixedly connected with an electromagnetic block 9, and a slot 10 is provided on the lower surface of the electromagnetic block 9. The inner wall of the wear-resistant sleeve 12 is slidably connected with a fixed rod 13, one end of the fixed rod 13 is embedded with an iron block 14, and a sleeve 15 is fixedly connected to the side wall of one end of the fixed rod 13. The surface of the sleeve 15 is fixedly connected with a push plate 16, and a connecting sleeve 11 is embedded on the surface of the door body 2 and located below the wear-resistant sleeve 12. The inner wall of the connecting sleeve 11 is slidably connected with the push plate 16, and a compressed return spring 17 is arranged on the inner wall of the connecting sleeve 11 and located above the push plate 16. The handle 25 is connected to the locking mechanism signal. After the door body 2 is closed, the slot 10 is aligned with the iron block 14. When the handle 25 is pulled upward, the electromagnetic block 9 is energized to generate magnetic force. Under the traction of the magnetic force, the iron block 14 is pulled through the sleeve 15 and the push plate 16 to pull the reset spring 17 to contract, generate elastic force, reduce the moving speed of the iron block 14, reduce the collision force between the iron block 14 and the electromagnetic block 9, increase the service life of the iron block 14 and the electromagnetic block 9, and reduce the noise generated. After the elastic force of the reset spring 17 is balanced with the magnetic force of the electromagnetic block 9, the iron block 14 is inserted into the slot 10, and the bottom of the expanded tube 8 is provided with a wide mouth to facilitate the entry of the fixing rod 13, so that the door body 2 is locked. When the handle 25 is pulled downward, the electromagnetic block 9 is de-energized, and the reset spring 17 and the push plate 16 drive the sleeve 15 and the fixing rod 13 to reset, so that the door body 2 can rotate, and the connecting sleeve 11 limits the moving direction of the push plate 16, and the wear-resistant sleeve 12 and the fixing rod 13 are closely matched, so that the interior of the connecting sleeve 11 is not easy to get dust.

[0032] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6The first magnetic strip 18 and the second magnetic strip 19 both include a wear-resistant protective layer 20, the inner wall of the wear-resistant protective layer 20 is fixedly connected with a heat insulation layer 21, the inner wall of the heat insulation layer 21 is fixedly connected with a permanent magnet 22, the inner wall of the door edge 1 and the first magnetic strip 18 and the second magnetic strip 19 are fixedly connected with a matching strip 23, the surface of the matching strip 23 is fixedly connected with an elastic pad, the surface of the door edge 1 is provided with a mounting groove 24, the front corner of the door edge 1 is set as a rounded corner, the front of the door body 2 is provided with an installation area 26, the inner wall of the installation area 26 is fixedly connected with a transparent soundproof window 27, the wear-resistant protective layer 20 is made of elastic material, so that the surfaces of the first magnetic strip 18 and the second magnetic strip 19 can be moved in the event of a collision. Buffering is performed to prevent the user from being injured. When the door body 2 is closed, the first magnetic strip 18 and the second magnetic strip 19 are close to the matching strip 23. The matching strip 23 is made of iron. The permanent magnet 22 and the matching strip 23 attract each other, so that the first magnetic strip 18 and the second magnetic strip 19 fit with the elastic pad, thereby sucking the door body 2. When the door is not locked, the door body 2 is not easily opened by air flow. The insulation layer 21 makes it difficult for the external temperature to affect the permanent magnet 22, making it difficult for the permanent magnet 22 to be demagnetized. The door edge 1 is installed on the wall through the installation groove 24 on the door edge 1. The transparent soundproof window 27 uses single-light-transmitting glass. The situation outside the door is observed through the transparent soundproof window 27, and the internal situation of the door body 2 cannot be observed from the outside.

[0033] Working principle: Rotate the door body 2 to close it. When passing the electric auxiliary wheel 5, the rounded corners of the first magnetic strip 18 can better cooperate with the electric auxiliary wheel 5, so that the electric auxiliary wheel 5 fits tightly with the side of the door body 2. The electric auxiliary wheel 5 rotates and cooperates, so that the resistance is small when the door body 2 is closed. In the above process, the door body 2 pushes the electric auxiliary wheel 5 toward the inside of the installation sleeve 3, and the electric auxiliary wheel 5 does not hinder the closing of the door body 2. At this time, the damper 4 generates damping to reduce the moving speed of the electric auxiliary wheel 5, and buffers when the door body 2 rotates quickly, reducing the force of the door body 2 colliding with the door edge 1 when closing, thereby reducing the noise generated when the door body 2 is closed. The first magnetic strip 18 and the second magnetic strip 19 are close to the matching strip 23, and the material of the matching strip 23 is iron. The permanent magnet 22 and the matching strip 23 attract each other, so that the first magnetic strip 18 and the second magnetic strip 19 fit with the elastic pad, thereby sucking the door body 2. When the door is unlocked, the door body 2 is not easily opened by air flow. The handle 25 is pulled upward, and the electromagnetic block 9 is energized to generate magnetic force. Under the traction of the magnetic force, the iron block 14 is pulled through the sleeve 15 and the push plate 16 to pull the reset spring 17 to shrink, generate elastic force, reduce the moving speed of the iron block 14, reduce the collision force between the iron block 14 and the electromagnetic block 9, and increase the service life of the iron block 14 and the electromagnetic block 9. At the same time, reduce the noise generated. After the elastic force of the reset spring 17 is balanced with the magnetic force of the electromagnetic block 9, the iron block 14 is inserted into the slot 10, so that the door body 2 is locked. When unlocking and opening the door, the handle 25 is pulled downward to send an opening signal to the electric auxiliary wheel 5. The electromagnetic block 9 is powered off, and the reset spring 17 pushes the plate 16 to drive the sleeve 15 and the fixed rod 13 to reset, so that the door body 2 can rotate. The electric auxiliary wheel 5 rotates to provide auxiliary power for the rotation of the door body 2, so that the door body 2 can be opened effortlessly and is not easy to produce a sense of stagnation.
