Description

Technical Field

[0001] This utility model relates to the field of ground suction technology, and in particular to a hidden ground suction structure. Background Technology

[0002] Currently, most mainstream swing door door closers on the market consist of two parts: a base module (fixed to the ground) and a magnetic module (fixed to the door). These two parts work together magnetically to achieve door positioning. The method of fixing the magnetic module to the door is crucial to the ease of installation and the integrity of the door. Existing technologies primarily rely on screws or adhesive, but both methods have unavoidable drawbacks in practical applications, severely limiting the effectiveness and user experience of the door closer. Specifically, when using screws to fix the magnetic module, the operator needs to measure and mark the bottom or side of the door on-site. Then, a drill is used to drill holes at the marked locations. The screws are then passed through the mounting holes of the magnetic module and screwed into the drilled holes, achieving fixation through thread engagement. This process requires extremely high precision: if the drilling position is off, the magnetic module will not align properly with the base module after installation, affecting the subsequent door positioning accuracy; if the drilling depth is too deep, it will penetrate the door or damage its internal structure, causing irreversible damage; if the screws are tightened too forcefully, the magnetic module's outer shell may crack, rendering it unusable; and the screw holes left after drilling will damage the integrity of the door surface, severely affecting its aesthetics. While using adhesive to fix the magnetic module eliminates the need for drilling, it requires thorough cleaning of the door's mounting area to remove dust, oil, and other impurities. Structural adhesive or silicone sealant is then evenly applied to the magnetic module's bonding surface before pressing it into the pre-set position on the door, relying on the adhesive's bonding strength after curing. However, this method also has significant drawbacks: First, the amount of adhesive applied is difficult to control precisely. Applying too much adhesive can lead to excess overflow, leaving hard-to-clean residue that contaminates the door surface. Applying too little adhesive results in insufficient bonding strength, causing the magnetic module to loosen, detach, and lose its positioning function under the vibrations and impacts of frequent door opening and closing. Second, the adhesive requires a long curing time, during which the door cannot be used normally, severely impacting the construction progress. Furthermore, if the magnetic module malfunctions and needs replacement later, the cured adhesive is difficult to remove, and forcibly peeling it off can scratch the door surface, causing secondary damage. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a concealed suction structure.

[0004] A concealed suction structure designed for this purpose includes a door body, a magnetic suction module, a base module, and a magnetic suction element; the magnetic suction element is fixedly installed on the door body; the magnetic suction module is magnetically attracted to the magnetic suction element and is installed at the bottom of the door body; when the door body rotates to a first position along the opening direction; the magnetic suction module can attract the base module to constrain the door body to remain in the first position.

[0005] Preferably, the magnetic module is provided with a downwardly extending limiting part; the base module includes a base and a suction member; the suction member is movable or rotatable relative to the base; when the door rotates to the first position along the opening direction; the magnetic module and the suction member are attracted to each other, so that the suction member is attached to the magnetic module and abuts against the limiting part.

[0006] Preferably, the magnetic module includes a frame that is fixed to the lower surface of the door and a magnet disposed within the frame.

[0007] Preferably, the magnetic module is provided with an upwardly extending positioning flange; the positioning flange is aligned with the wall surface of the door facing the opening direction.

[0008] Preferably, the door body includes a door panel and a door frame; the door panel is fixedly installed inside the door frame; and the magnetic suction device is embedded in the door frame.

[0009] Compared with the prior art, in this solution, the magnetic module is directly attracted and fixed to the magnetic parts fixed on the door by magnetic attraction, eliminating the need for on-site processing operations such as drilling and gluing on the door. This avoids irreversible damage to the door caused by screw fastening or glue application errors. At the same time, it eliminates tedious steps such as drilling positioning and glue curing. Even non-professionals can quickly complete the assembly, greatly reducing the installation threshold and operation risk. Attached Figure Description

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] See Figures 1-6 A concealed suction structure includes a door body 10, a magnetic suction module 20, a base module 30, and a magnetic suction element 40; the magnetic suction element 40 is fixedly disposed on the door body 10; the magnetic suction module 20 is magnetically attracted to the magnetic suction element 40 and disposed at the bottom of the door body 10; when the door body 10 is rotated to a first position along the opening direction; the magnetic suction module 20 can be attracted to the base module 30 to constrain the door body 10 to remain in the first position.

[0013] The working principle of this concealed door-mounted suction structure revolves around the magnetic attraction of each component and its linkage with the door's movement. The specific process is as follows: During the initial assembly stage of the structure, the magnetic component 40 is pre-fixed to the door body 10, and the magnetic module 20 is tightly attracted and fixed to the bottom of the door body 10 by the magnetic attraction between itself and the magnetic component 40, forming an integrated component of "door body 10-magnetic component 40-magnetic module 20". At this time, the base module 30 needs to be installed in a preset position on the ground (matching the position directly below or corresponding to the contact position of the magnetic module 20 when the door body 10 is rotated to the first position) in accordance with the movement trajectory of the magnetic module 20. When the door 10 is closed, the door 10 is attached to the door frame. At this time, the magnetic module 20 is located away from the base module 30 along with the door 10. There is no magnetic attraction between the two. Only the magnetic module 20 and the magnetic part 40 on the door 10 are attracted to each other, ensuring that the magnetic module 20 is stably fixed at the bottom of the door 10 and does not fall off or shift. When the user pushes the door 10 in the opening direction, the door 10 rotates around the door hinge, causing the magnetic suction module 20 at the bottom to move in a circular motion. As the door 10 continues to rotate, the magnetic suction module 20 gradually approaches the base module 30 on the ground; when the door 10 rotates to the preset first position, the magnetic suction module 20 moves to the position corresponding to the base module 30, and the magnetic attraction between the two is instantly activated, achieving a tight attraction.

[0014] In this attracted state, the magnetic module 20 is simultaneously subjected to dual magnetic attraction constraints from the magnetic component 40 and the base module 30: on the one hand, the attraction between the magnetic module 20 and the magnetic component 40 ensures that its fixed relationship with the door 10 remains unchanged; on the other hand, the attraction between the magnetic module 20 and the base module 30 forms a positioning connection between the door 10 and the ground, which counteracts the tendency of the door 10 to close due to its own weight, airflow disturbance or slight collision, thereby constraining the door 10 to remain stably in the first position and achieving reliable positioning after the door is opened. When the user needs to close the door 10, they only need to apply an external force in the closing direction to the door 10. This external force is greater than the magnetic attraction force between the magnetic module 20 and the base module 30, which will separate the two. Then the door 10 continues to rotate in the closing direction, and the magnetic module 20 moves away from the magnetic attraction range of the base module 30 along with the door 10 until the door 10 returns to the closed state, completing a complete "open-position-close" usage cycle.

[0015] See Figure 2 , Figure 4 ,and Figure 6 The magnetic module 20 is provided with a downwardly extending limiting part 200; the base module 30 includes a base 310 and a suction member 320; the suction member 320 is movable or rotatable relative to the base 310; when the door 10 rotates to the first position along the opening direction; the magnetic module 20 and the suction member 320 are attracted, so that the suction member 320 is attached to the magnetic module 20 and abuts against the limiting part 200. This abutting structure can directly prevent the door 10 from continuing to rotate in the opening direction, forming a mechanical limit, avoiding the door edge, lock and wall from colliding due to excessive rotation, thereby protecting the door, lock and wall from damage, extending the service life of the door and lock and reducing maintenance costs.

[0016] See Figure 2 The magnetic module 20 includes a frame 210 that is fixedly attached to the lower surface of the door 10 and a magnet 220 disposed within the frame 210. In the magnetic module 20, the frame 210 is fixedly attached to the lower surface of the door 10, providing a stable mounting carrier for the internal magnet 220 and ensuring a firm connection between the magnetic module 20 and the door 10, preventing displacement of the module when the door rotates. The magnet 220 within the frame 210 is the core magnetic component. On one hand, it can engage with the magnetic component 40 on the door 10, fixing the magnetic module 20 at the bottom of the door 10. On the other hand, when the door 10 rotates to the first position, it can engage with the engaging component 320 of the base module 30, working with the limiting part 200 to complete door positioning and over-rotation protection. In this invention, the magnetic attractant 40 is a magnet and is attracted to the magnet 220.

[0017] In this utility model, the limiting part 200 and the frame 210 are an integral structure.

[0018] See Figure 4 and Figure 6The magnetic module 20 is provided with an upwardly extending positioning flange 230; the positioning flange 230 and the wall surface 101 of the door 10 facing the opening direction are connected. This structure can specifically solve the problem of separation between the magnetic module 20 and the door 10: when the door 10 is in the first position, the door tends to move in the opening direction under the force. While the suction member 320 blocks the movement of the door, it can easily cause the magnetic module 20 to generate a force that moves in the opposite direction to the opening direction; the fit between the positioning flange 230 and the wall surface 101 can directly constrain the movement of the magnetic module 20 in this direction, ensuring that the magnetic module 20 is always stably attracted to the door 10 and preventing them from separating.

[0019] In this utility model, the positioning flange 230 and the frame 210 are an integral structure.

[0020] See Figure 6 The door body 10 includes a door panel 100 and a door frame 110; the door panel 100 is fixedly disposed in the door frame 110; the magnetic suction member 40 is embedded in the door frame 110.
