Description

Technical Field

[0001] The present invention relates to the technical field related to magnetic attraction of cabinet doors, and particularly to a novel magnetic attraction structure for cabinet doors. Background Art

[0002] In daily life and the layout of various spaces, as an indispensable storage and functional carrier, cabinets are widely used in many scenarios such as homes, offices, and commercial places. In the actual use process of various cabinets, the opening and closing structure of the cabinet door is a key element. It not only directly determines the convenience and operation experience when users open and close the cabinet door, affects the efficiency of daily access to items, but also relates to the overall safety and stability of the cabinet. A reasonable and high-quality cabinet door opening and closing structure can effectively reduce the wear and the probability of failure during the use of the cabinet door, extend the service life of the cabinet, and at the same time play a better protective role for the items inside the cabinet to a certain extent, preventing damage to the items due to improper opening and closing of the cabinet door. Therefore, there is a particular need for a novel magnetic attraction structure for cabinet doors.

[0003] However, the existing cabinet door opening and closing methods have many defects: The mechanical lock structure is usually relatively complex with numerous components. It is not only difficult to install and disassemble, but also prone to failure after long-term use and requires frequent maintenance. The mechanical lock structure is extremely likely to increase the use cost and maintenance difficulty due to problems such as wear and aging of components.

[0004] The cost of hardware such as hinges is relatively high. Secondly, the cabinet door needs to be drilled. The hinges can be seen when the cabinet door is opened, which affects the aesthetics. Moreover, the hinges have a fixed opening and closing angle, and the opening angle of the cabinet door is limited by the hinges.

[0005] When using hardware such as a pop-up device, when the cabinet door is opened and closed, the user must press the cabinet door by hand to pop out the cabinet door. If it is a cabinet door with a mirror surface (or a glass door) such as a mirror cabinet, it is easy to leave finger prints and stains, and both opening and closing the door require pressing operations.

[0006] In addition, the existing hinges and pop-up devices will be exposed when the cabinet door is opened, affecting the overall aesthetics and coordination of the cabinet and the use experience. Summary of the Invention

[0007] The object of the present invention is to provide a new magnetic attraction structure for cabinet doors, so as to solve the many defects existing in the existing cabinet door opening and closing methods in the above-mentioned background technology. The mechanical lock structure is usually relatively complex with numerous components. It is not only difficult to install and disassemble, but also prone to failures after long-term use and requires frequent maintenance. The mechanical lock structure is extremely likely to have problems such as wear and aging of components, increasing the use cost and maintenance difficulty. At the same time, although some magnetic attraction structures simplify the operation to a certain extent, there are problems of insufficient or unstable suction force, resulting in the cabinet door not closing tightly, prone to gaps, affecting the sealing and aesthetics of the cabinet body, and may also cause damage or loss of items in the cabinet. In addition, the existing door switch designs are often relatively exposed, affecting the overall aesthetics and coordination of the cabinet body, and the operation is not convenient enough, making it difficult to apply force, thus affecting the use experience.

[0008] To achieve the above object, the present invention provides the following technical solution: A new magnetic attraction structure for cabinet doors, including a cabinet body and a cabinet door. The cabinet door is rotationally connected to the cabinet body through an upper rotating shaft and a lower rotating shaft. A magnetic attraction lock body is provided at the bottom inside the cabinet body, and a door switch body is provided at the bottom inside the cabinet body. A door switch magnetic attraction is provided at the bottom of the cabinet door, and a door lock magnetic attraction is provided at the bottom of the cabinet door. The magnetic attraction lock body includes a magnetic attraction lock housing and a magnetic attraction lock magnet, and the magnetic attraction lock magnet is arranged inside the magnetic attraction lock housing. The door switch body includes a door switch magnet and a door switch handle, and the door switch magnet is installed on the door switch handle. The door switch handle can drive the door switch magnet to move. When the cabinet door is closed to the cabinet body, the door lock magnetic attraction aligns with the magnetic attraction lock magnet, and the magnetic attraction lock magnet pops up and contacts the cabinet door to form a frictional force, making it difficult for the cabinet door to be opened without external force after being closed. And the door switch magnetic attraction aligns with the door switch body. When the cabinet door is closed and the door switch handle is controlled to drive the door switch magnet to approach the door switch magnetic attraction, the door switch magnet can act on the door switch magnetic attraction to form an external force for opening the cabinet door, and this external force is greater than the frictional force between the magnetic attraction lock body and the cabinet door, causing the cabinet door to open.

[0009] Preferably, the magnetic attraction lock body further includes a magnetic attraction lock telescopic head. The magnetic attraction lock magnet is fixedly connected to the magnetic attraction lock telescopic head, and the two move synchronously up and down inside the magnetic attraction lock housing. The magnetic attraction lock telescopic head is made of a flexible material. When the cabinet door is closed, the flexible material can provide a greater frictional force to prevent the cabinet door from opening naturally. At the same time, it reduces the noise generated when the magnetic attraction lock telescopic head pops up.

[0010] Preferably, the magnetic attraction lock telescopic head is made of silicone or rubber.

[0011] Preferably, when the door lock magnetic attraction aligns with the magnetic attraction lock magnet, the magnetic attraction lock telescopic head is in close contact with the cabinet door, and the magnetic attraction lock magnet is not in contact with the door lock magnetic attraction.

[0012] Preferably, the door switch handle is rotatably connected to the cabinet body, and the door switch handle rotates synchronously with the door switch magnet; during the rotation process, the distance between the door switch magnet and the door switch magnetic attraction in the closed state of the cabinet door changes.

[0013] Preferably, the magnetic attraction lock housing is fixedly connected to the cabinet body, the magnetic attraction lock body is located inside the cabinet, and the lifting of the magnetic attraction lock magnet and the magnetic attraction lock telescopic head in the magnetic attraction lock housing does not affect the rotation of the cabinet door.

[0014] Preferably, the door switch magnetic attraction is fixedly installed on the cabinet door, and the cabinet door corresponds to the door switch magnet when the door switch handle rotates to a specific angle. The door lock magnetic attraction is fixedly installed on the cabinet door, and the cabinet door corresponds to the magnetic attraction lock magnet when the cabinet body is in the closed state.

[0015] Preferably, the magnetic attraction lock magnet and the magnetic attraction lock telescopic head are fixedly connected to form an integral body that can move in a specific direction inside the magnetic attraction lock housing, and the moving direction of the integral body is associated with the closing and opening directions of the cabinet door.

[0016] Preferably, the door switch handle is installed on the edge of the cabinet door, and the rotation center of the door switch handle is independent of the rotation center of the cabinet door.

[0017] Preferably, a layered component is provided inside the cabinet body. The layered component includes an installation base. The installation base is fixedly installed inside the cabinet body. A motor is fixedly installed on the outer side of the installation base. The output end of the motor is fixedly installed with a positive and negative thread double-headed lead screw. A lead screw seat is fixedly installed inside the cabinet body. A layered plate is threadedly connected to the outer side of the positive and negative thread double-headed lead screw. A slide rail is fixedly installed inside the cabinet body. A guide rod is slidably connected to the inner side of the layered plate. The slide rail is slidably connected to the layered plate. There are two identical sets of layered plates, and the two sets of layered plates are symmetrically distributed about the horizontal center line of the positive and negative thread double-headed lead screw. There are two identical guide rods.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The novel cabinet door magnetic attraction structure of the present invention greatly simplifies the opening and closing operation of the cabinet door through a unique magnetic attraction and repulsion design. When opening the cabinet door, the user only needs to rotate the door switch handle, and the repulsive force generated between the door switch magnet and the door switch magnetic attraction can automatically push open the cabinet door.

[0019] When opening the door, the user can operate the switch handle of the switch body to make the cabinet door bounce open. Compared with the pressing type rebounder, there is no need to press the cabinet door with fingers, so there will be no finger marks left on the cabinet door. Especially when the surface of the cabinet door is installed with glass / mirror, it can be cleaner.

[0020] When closing the door, the magnetic lock magnet and the magnet of the magnetic absorption lock attract each other, and the telescopic head of the magnetic absorption lock moves accordingly to hold against the cabinet door, achieving an easy and quick closing action, significantly reducing the difficulty of use for the user; when the cabinet door is closed, since the magnet pops up to hold against the lower part of the cabinet door to make the cabinet door close automatically, even if the cabinet body is tilted during installation by the carpenter, there will be no situation where the cabinet door cannot be firmly closed and opens automatically. When the user closes the cabinet door, they only need to gently close the cabinet door, and the cabinet door will be automatically attracted and limited by the magnet after reaching the cabinet body by inertia, without the need for a bumper like in the case where the user has to press it hard again to close it firmly.

[0021] Under the attraction of the magnetic lock magnet and the magnet of the magnetic absorption lock, the telescopic head of the magnetic absorption lock can tightly hold against the cabinet door, forming a stable locking state, effectively preventing the cabinet door from accidentally opening due to external force collision, vibration, cabinet body skew and other factors, avoiding the items in the cabinet from falling, being damaged or lost. At the same time, the reset part equipped on the door switch magnet can ensure that in the normal state, the door switch magnet and the door switch magnetic absorption are staggered from each other, without generating repulsive force, preventing the cabinet door from accidentally bouncing open during the closing process, providing reliable safety protection for the user, especially suitable for the cabinet body storing valuables or fragile items.

[0022] 2. In the preferred solution, the magnetic absorption lock body further includes a telescopic head of the magnetic absorption lock, and the telescopic head of the magnetic absorption lock is made of a flexible material. When the cabinet door is closed and the magnetic lock magnet aligns with the magnet of the magnetic absorption lock, the telescopic head of the magnetic absorption lock will first hit the bottom of the cabinet door. Since it is a flexible material, there will be no large noise generated. And there is a gap reserved between the magnetic lock magnet and the magnet of the magnetic absorption lock to avoid noise generated by their collision, enabling silent door closing. The cabinet door is restricted in movement when closing, so it will not make noise due to hitting the cabinet body either.

[0023] 3. By adopting the novel cabinet door magnetic absorption structure in the present invention, it is no longer necessary to install hardware such as hinges, which can save costs. At the same time, the opening and closing angle of the cabinet door can be more arbitrary, and even the cabinet door can be opened and closed without resistance.

[0024] 4. Since all the cabinet door magnetic absorption structures are installed inside the cabinet body or under the cabinet door, which are positions that are not easily seen, when the cabinet door is opened, the magnetic absorption structure is not easily seen and is relatively concealed, making the appearance cleaner.

[0025] 5. The novel magnetic attraction structure of the cabinet door of the present invention is rotationally connected to the cabinet body through the upper rotating shaft and the lower rotating shaft, providing stable rotational support for the cabinet door, reducing the shaking and deviation of the cabinet door during the opening and closing process. The magnetic attraction lock body is fixedly connected to the cabinet door through the magnetic attraction lock housing, ensuring the stable and reliable lifting movement of the magnetic attraction lock magnet and the magnetic attraction lock telescopic head within the magnetic attraction lock housing, without being affected by the rotation of the cabinet door. The door lock magnetic attraction and the door switch magnetic attraction are respectively fixedly installed at corresponding positions on the cabinet body, precisely matching with the door switch magnet and the magnetic attraction lock magnet on the cabinet door, ensuring the stable transmission of magnetic attraction and repulsive force. This enables the entire magnetic attraction structure to maintain good performance during long-term use, reducing the risk of failure caused by structural looseness or component displacement, and extending the service life of the product. Moreover, the door switch magnet is hidden inside the door switch handle, with only the small door switch handle exposed. This hidden design makes the appearance of the cabinet body more concise and smooth, avoiding the obtrusiveness brought by the exposure of traditional door locks or magnetic attraction structures, and being able to perfectly integrate with cabinet bodies of various styles, enhancing the overall aesthetics and decorativeness of the cabinet body. At the same time, the installation position of the door switch handle is carefully designed, which is not only convenient for users to operate but also does not affect the appearance layout of the cabinet body, achieving the organic unity of functionality and aesthetics.

[0036] The following description is used to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments in the following description are only examples, and other obvious variations can be conceived by those skilled in the art. The basic principles of the present invention defined in the following description can be used in other implementation schemes, variation schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present invention.

[0037] Embodiment 1 Please refer to Figures 1-9 , the present invention provides a technical solution: a new type of magnetic attraction structure for a cabinet door, including a cabinet body 1 and a cabinet door 4. The cabinet door 4 is rotatably connected to the cabinet body 1 through an upper rotating shaft 2 and a lower rotating shaft 3. A magnetic attraction lock body 5 and a door switch body 6 are arranged at the bottom inside the cabinet body 1. A door switch magnetic attraction 7 and a door lock magnetic attraction 8 are arranged at the bottom of the cabinet door 4.

[0038] Furthermore, the magnetic attraction lock body 5 includes a magnetic attraction lock housing 51, a magnetic attraction lock magnet 52, and a magnetic attraction lock telescopic head 53. The magnetic attraction lock magnet 52 and the magnetic attraction lock telescopic head 53 are arranged inside the magnetic attraction lock housing 51, and the magnetic attraction lock magnet 52 is fixedly connected to the magnetic attraction lock telescopic head 53. The magnetic attraction lock magnet 52 and the magnetic attraction lock telescopic head 53 move up and down synchronously inside the magnetic attraction lock housing 51. By providing the magnetic attraction lock body 5, they can move up and down synchronously inside the magnetic attraction lock housing 51, ensuring that when the door lock magnetic attraction 8 and the magnetic attraction lock magnet 52 attract each other, the magnetic attraction lock telescopic head 53 can accurately move upward and be in close contact with the cabinet door 4, thereby effectively restricting the further closing of the cabinet door 4 and ensuring the stability and reliability of the closing of the cabinet door.

[0039] Furthermore, the door switch body 6 includes a door switch magnet 61 and a door switch handle 62. The door switch magnet 61 is installed on the door switch handle 62. By providing the door switch body 6, the door switch magnet 61 can rotate synchronously with the rotation of the door switch handle 62. When the user rotates the door switch handle 62, the door switch magnet 61 rotates accordingly, and then interacts with the door switch magnetic attraction 7 on the cabinet body 1.

[0040] Furthermore, when the magnetic lock body 5 (the magnetic lock magnet 52 thereof) aligns with the door lock magnetic attraction 8, the magnetic lock magnet 52 will drive the magnetic lock telescopic head 53 to bounce upward and strike the cabinet door 4. The magnetic lock telescopic head 53 is in close contact with the cabinet door 4, forming sufficient frictional force therebetween to prevent the cabinet door from shaking due to external force or its own gravity, ensuring the tightness of the closed cabinet door, effectively avoiding the entry of external dust, moisture, etc. into the cabinet body 1, and protecting the items inside the cabinet.

[0041] Furthermore, the door switch handle 62 is rotatably connected to the cabinet body 1, and the door switch handle 62 rotates synchronously with the door switch magnet 61. By rotating the door switch handle 62, the distance between the door switch magnet 61 and the door switch magnetic attraction 7 can be controlled. The greater the distance, the smaller the repulsive force, and vice versa, the closer the distance, the greater the repulsive force. When the cabinet door 4 is closed, the door switch magnetic attraction 7 approaches the door switch magnet 61, causing the door switch handle 62 to reset outward (a return spring or other return components can be additionally added to assist in the reset). When the user needs to open the cabinet door 4, only need to press the door switch handle 62 inward to open the cabinet door 4.

[0042] The above operations ensure the convenience and coherence of user operations. The user only needs to gently rotate the door switch handle 62 to drive the rotation of the door switch magnet 61, making it mutually repulsive with the door switch magnetic attraction 7, thereby realizing the automatic opening of the cabinet door. Moreover, the rotation center of the door switch handle 62 is independent of the rotation center of the cabinet door 4, and the rotation of the door switch handle 62 is not affected by the opening and closing of the cabinet door 4, further improving the stability and reliability of the operation.

[0043] Furthermore, the magnetic lock housing 51 is fixedly connected to the cabinet body 1. The magnetic lock body 5 is located inside the cabinet body 1, and the lifting of the magnetic lock magnet 52 and the magnetic lock telescopic head 53 in the magnetic lock housing 51 does not affect the rotation of the cabinet door 4. Only when the door lock magnetic attraction 8 of the cabinet door 4 approaches will it act on the magnetic lock body 5. By setting the fixed connection between the magnetic lock housing 51 and the cabinet door 4, regardless of the opening and closing state of the cabinet door 4, the magnetic lock body 5 can work normally, ensuring the independence and stability of the magnetic lock function.

[0044] Further, the door switch magnetic attraction 7 is fixedly installed on the cabinet door 4, and the cabinet door 4 corresponds to the door switch magnet 61 when the door switch handle 62 rotates to a specific angle. By setting the door switch magnetic attraction 7 fixedly installed on the cabinet door 4, it is ensured that when the user rotates the door switch handle 62, the door switch magnet 61 can accurately generate a repulsive force with the door switch magnetic attraction 7, thereby pushing the cabinet door 4 to open automatically, improving the sensitivity and reliability of the door switch, making the user operation smoother. The door lock magnetic attraction 8 is fixedly installed on the cabinet body 1, and the cabinet body 1 corresponds to the magnetic lock magnet 52 when the cabinet door 4 is in the closed state. By setting the door lock magnetic attraction 8 fixedly installed on the cabinet body 1, during the closing process of the cabinet door, the door lock magnetic attraction 8 and the magnetic lock magnet 52 attract each other, and the generated attraction drives the magnetic lock telescopic head 53 to move upward, realizing the stable closing of the cabinet door, ensuring that the magnetic lock can work normally when the cabinet door is closed, and enhancing the stability and sealing performance of the cabinet door closing.

[0045] Further, the magnetic lock magnet 52 and the magnetic lock telescopic head 53 are fixedly connected to form an integral body that can move in a specific direction within the magnetic lock housing 51, and the overall movement direction is associated with the closing and opening directions of the cabinet door 4. By setting the magnetic lock magnet 52 and the magnetic lock telescopic head 53 fixedly connected to form an integral body that can move in a specific direction within the magnetic lock housing 51, when the cabinet door is opened, with the repulsive action between the door switch magnet 61 and the door switch magnetic attraction 7, the cabinet door opens, and the magnetic lock magnet 52 and the magnetic lock telescopic head 53 move downward under the action of gravity or other reset mechanisms, preparing for the next closing of the cabinet door, making the operation of the magnetic lock closely cooperate with the opening and closing of the cabinet door, and improving the coordination and efficiency of the entire system.

[0046] Further, the door switch handle 62 is installed on the edge of the cabinet door 4, and the rotation center of the door switch handle 62 is independent of the rotation center of the cabinet door 4. By setting the door switch handle 62 installed on the edge of the cabinet door 4, the design of installing on the edge of the cabinet door 4 is convenient for user operation, conforms to the ergonomic principle, enabling the user to easily rotate the door switch handle 62, and the design with independent rotation centers further improves the stability and reliability of the door switch operation, avoiding interference with the door switch operation caused by the rotation of the cabinet door, and ensuring the normal realization of the door switch function.

[0047] Embodiment 2 Further, the layered component 9 includes a mounting base 901, the mounting base 901 is fixedly installed on the inner side of the cabinet 1, a motor 902 is fixedly installed on the outer side of the mounting base 901, a positive and negative double-headed screw 903 is fixedly installed on the output end of the motor 902, a screw seat 904 is fixedly installed on the inner side of the cabinet 1, and a layered plate 906 is threadedly connected to the outer side of the positive and negative double-headed screw 903, a slide rail 905 is fixedly installed on the inner side of the cabinet 1, and a guide rod 907 is slidably connected to the inner side of the layered plate 906, and the slide rail 905 is slidably connected to the layered plate 906. Two identical groups of shelf plates 906 are provided, and the two groups of shelf plates 906 are symmetrically distributed about the horizontal center line of the positive and negative double-ended screw rod 903, and two identical guide rods 907 are provided. By providing a layering component 9, the internal space of the cabinet 1 is flexibly utilized, ensuring that the layer plates 906 remain stable during movement without tilting or shaking. By providing the layering component 9, the user can flexibly adjust the layer height inside the cabinet 1 according to actual needs, so as to better store items of different sizes, thereby greatly improving the utilization and practicality of the space of the cabinet 1.

[0048] Component selection and installation: Select magnetic lock magnet 52 and door lock magnet 8 with high magnetism and strong stability to ensure that under normal use environment, the attraction between the two is sufficient to enable the magnetic lock telescopic head 53 to stably lock the cabinet door. The thickness of the rubber pad layer on the surface of the magnetic lock telescopic head 53 is set, which has good flexibility and high friction coefficient, which can not only effectively prevent scratches on the cabinet door, but also provide sufficient friction. The door switch magnet 61 adopts neodymium iron boron permanent magnet material with strong magnetism. The door switch magnet 7 uses matching magnetic material to ensure that the repulsive force meets the door opening requirement. The reset part of the door switch handle 62 adopts a torsion spring, which is installed on the rotating shaft of the door switch handle 62 to ensure that the door switch magnet 61 can be accurately reset. The magnetic lock is installed at the inner edge of the cabinet door to ensure that the magnetic lock telescopic head 53 can be in close contact with the cabinet door when it rises; the door switch is installed at a position on the edge of the cabinet door that is easy to operate to ensure that the user can easily rotate the door switch handle 62.

[0049] Actual application scenarios: The new cabinet door magnetic attraction structure is applied to high-quality display cabinets. In daily use of high-quality display cabinets, when the staff closes the cabinet door, the door lock magnet 8 and the magnetic lock magnet 52 are quickly attracted, and the magnetic lock telescopic head 53 rises smoothly to hold the cabinet door, effectively protecting the items in the display cabinet from damage due to the shaking of the cabinet door. When the display cabinet needs to be opened, the staff rotates the door switch handle 62, the door switch magnet 61 and the door switch magnet 7 repel each other, and the cabinet door automatically pops open a short distance, which is convenient for the staff to take or place display items. The whole operation process is simple and convenient, and the appearance of the display cabinet is neat and beautiful, which improves the display effect.

[0050] Embodiment 3 Component improvement and optimization: Based on Embodiment 2, the magnetic lock is optimized. The outer shell of the magnet 52 of the magnetic lock is made of corrosion-resistant stainless steel to improve its durability and aesthetics. At the same time, the structure of the telescopic head 53 of the magnetic lock is improved, and a spring device is added inside it to make the telescopic head move more smoothly during the rising and falling processes and can automatically adjust the force to hold the cabinet door according to the thickness of the cabinet door. For the door switch, the material of the door switch handle 62 is changed to high-strength aluminum alloy to reduce the weight while increasing its strength. The reset part of the door switch magnet 61 is replaced with an elastic rubber strip, which can not only provide a stable reset force but also play a buffering role during the rotation of the door switch to reduce noise.

[0051] Different application scenarios and effects: The improved new cabinet door magnetic structure is applied to high-end wine cabinets. In the usage scenario of wine cabinets, since wine products have high requirements for the stability of the storage environment, the improved magnetic lock can better ensure that the cabinet door is closed tightly, effectively preventing external air from entering and affecting the quality of wine products. The optimized design of the door switch makes the opening and closing operations of the cabinet door smoother and quieter, improving the user experience. In daily use, when the wine cabinet door is closed, the strong suction force of the magnetic lock makes the telescopic head tightly hold the cabinet door, maintaining the temperature and humidity stability inside the wine cabinet. When the user opens the wine cabinet, the repulsive force between the door switch magnet 61 and the door switch magnet 7 makes the cabinet door bounce open smoothly, and the buffering effect of the elastic rubber strip avoids the impact sound generated during the rotation of the door switch, creating a more elegant usage environment for users.

[0052] Working principle: Before the operator installs the new cabinet door magnetic attraction structure, first ensure that the surfaces of the cabinet body 1 and the cabinet door 4 are flat and free of debris. Check whether components such as the upper rotating shaft 2, the lower rotating shaft 3, the magnetic attraction lock body 5, the door switch body 6, the door switch magnetic attraction 7, and the door lock magnetic attraction 8 are complete and undamaged. Install the upper rotating shaft 2 and the lower rotating shaft 3 at the corresponding positions of the cabinet body 1 and the cabinet door 4 respectively, ensuring that the rotating shafts are firmly installed so that the cabinet door 4 can be smoothly rotatably connected to the cabinet body 1 through the rotating shafts. An opening and closing test can be carried out to check whether the cabinet door rotates flexibly and there is no jamming phenomenon. Fix the magnetic attraction lock housing 51 of the magnetic attraction lock body 5 at the bottom inside the cabinet door 4, ensuring that the installation position of the magnetic attraction lock housing 51 is accurate and will not affect the normal opening and closing of the cabinet door. Install the magnetic attraction lock magnet 52 and the magnetic attraction lock telescopic head 53 inside the magnetic attraction lock housing 51, and ensure that they are fixedly connected and can move up and down synchronously inside the housing. After installation, manually test whether its up and down movement is smooth. Install the door switch magnet 61 on the door switch handle 62, and then install the door switch handle 62 with the installed door switch magnet 61 on the edge of the cabinet door 4, ensuring that the door switch handle 62 is smoothly rotatably connected to the cabinet door 4 and the rotation center of the door switch handle 62 is independent of the rotation center of the cabinet door 4. Install the door switch magnetic attraction 7 at the position corresponding to the door switch magnet 61 at the bottom inside the cabinet body 1, ensuring firm installation; install the door lock magnetic attraction 8 at the position corresponding to the magnetic attraction lock magnet 52 of the cabinet door 4 in the closed state at the bottom inside the cabinet body 1, ensuring that the door lock magnetic attraction 8 and the magnetic attraction lock magnet 52 can accurately correspond and attract each other when the cabinet door is closed. When the operator needs to open the cabinet door, the user holds the door switch handle 62 and rotates it in a specific direction. The rotation of the door switch handle 62 drives the door switch magnet 61 installed on it to rotate synchronously. When the door switch magnet 61 rotates to a specific angle corresponding to the door switch magnetic attraction 7 on the cabinet body 1, the door switch magnet 61 and the door switch magnetic attraction 7 repel each other, and the repulsive force of the door switch is greater than the magnetic attraction resistance on the magnetic attraction lock side, thereby pushing the cabinet door 4 to automatically pop open a small distance. At this time, the user only needs to pull the cabinet door 4 along the trend to fully open the cabinet door. Fix the installation base 901 inside the cabinet body 1, install the motor 902 outside the installation base 901, install the lead screw seat 904 inside the cabinet body 1 to support the left and right hand thread double lead screw 903, ensuring that all components are firmly installed. Install the two guide rods 907 inside the layered board 906 so that the layered board 906 can slide along the guide rods 907; fix the slide rail 905 inside the cabinet body 1, ensuring that the layered board 906 can be slidably connected to the slide rail 905;Threadedly connect the two groups of layered plates 906 to the outer side of the double-threaded lead screw 903 with opposite threads respectively, and ensure that the two groups of layered plates 906 are symmetrically distributed with respect to the horizontal center line of the double-threaded lead screw 903 with opposite threads. Start the motor 902, and observe whether the two groups of layered plates 906 can move smoothly along the lead screw in opposite or the same direction when the double-threaded lead screw 903 rotates. And during the movement, whether the guide rod 907 and the slide rail 905 can effectively play the roles of guiding and stabilizing, ensuring that the height of the layered plate 906 can be flexibly adjusted to meet the storage requirements of different items for the required operations. After using the cabinet body 1, align the cabinet door 4 with the cabinet body 1, and slowly push the cabinet door. When the cabinet door is close to the cabinet body 1 by a certain distance, the door lock magnet 8 on the cabinet body 1 attracts the magnet lock magnet 52 in the magnet lock body 5 on the cabinet door 4. The magnet lock magnet 52 moves upward under the action of the attraction force. Since the magnet lock magnet 52 is fixedly connected to the magnet lock telescopic head 53 and moves up and down synchronously, the magnet lock telescopic head 53 also moves upward accordingly. When the cabinet door continues to approach the cabinet body 1, the magnet lock telescopic head 53 gradually comes into close contact with the cabinet door 4, and uses the frictional resistance generated by the magnetic attraction to hold the cabinet door, so that the cabinet door stops closing further inward, completing the closing action of the cabinet door, and ensuring that the cabinet door is closed tightly and firmly.
