Detailed implementation manners
[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings.
[0034] It should be noted that all the expressions using "first" and "second" in the embodiments of the present utility model are for distinguishing two entities or parameters with the same name but different, so it can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation to the embodiments of the present utility model. The subsequent embodiments will not be elaborated one by one.
[0035] The terms of direction and position mentioned in the present utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only with reference to the direction or position of the attached drawings. Therefore, the terms of direction and position used are for explaining and understanding the present utility model, rather than a limitation to the protection scope of the present utility model.
[0036] A door stopper, as Figure 1 shown, includes a base part and a suction seat part. The base part is used for installation on the ground, and the suction seat part is used for installation on the door body. Specifically, the base part includes a bottom plate 100 and a first magnetic member 200. One end of the first magnetic member 200 is movably connected to the bottom plate 100 and the other end is provided with a first locking portion 210; the suction seat part includes a connecting member 300. A second magnetic member 400 is fixed on the connecting plate 310 and a second locking portion 330 is provided. When the second magnetic member 400 approaches the first magnetic member 200, there is a magnetic attraction between the first magnetic member 200 and the second magnetic member 400, which causes the first magnetic member 200 to move relative to the bottom plate 100, and then the first locking portion 210 and the second locking portion 330 form an abutting fit. As Figure 8 shown, after installing the door stopper, when the door rotates to the open state, the suction seat part approaches the base part, causing the second magnetic member 400 to approach the first magnetic member 200. The first magnetic member 200 moves relative to the bottom plate 100, and then the first locking portion 210 and the second locking portion 330 form an abutting fit. At this time, the door stopper will form a limit to prevent the door from further rotating and avoid the door hitting the wall surface.
[0037] Both the first magnetic member 200 and the second magnetic member 400 can be made of permanent magnets, or one of them can be made of a permanent magnet and the other can be made of a material that can be magnetically attracted, such as iron. In this embodiment, the first magnetic member 200 is an iron sheet and the second magnetic member 400 is a strong magnetic neodymium boron magnet. The bottom plate 100 and the connecting member 300 can be made of high-strength alloy materials to improve the service life.
[0038] As Figure 2 、 Figure 3 shown, the connecting member 300 has a connecting plate 310 for connecting to the bottom surface of the door body 500 and a limiting rib 320 connected to one end of the connecting plate 310. As Figure 8As shown in the figure, when installing the door stopper, the upper end surface of the connecting plate 310 is fixedly connected to the bottom surface of the door body 500 by adhesive connection, and the limiting rib 320 is attached to the side surface of the door body 500. The installation orientation of the limiting rib 320 is consistent with the opening direction of the door body 500, so that after the door body 500 is opened, the part of the limiting rib 320 close to the base. The suction seat part does not need to be fixed by bolt connection, and can be fixed by adhesive connection, so it can be directly installed on the aluminum frame door. Further, the second magnetic member 400 is fixed on the connecting plate 310 installed at the bottom of the door body 500, which is invisible and beautiful. However, during the long-term multiple opening and closing processes, the first locking portion 210 and the second locking portion 330 repeatedly abut and collide. If the connecting member 300 is only adhesively connected to the door body 500 through the connecting plate 310, the connection is unreliable. Therefore, the limiting rib 320 is further provided so that the limiting rib 320 abuts against the side surface of the door body 500, as Figure 8 shown, during the door opening process, the first locking portion 210 collides with the second locking portion 330, and the limiting rib 320 can eliminate the collision force, avoiding affecting the adhesive connection structure between the connecting plate 310 and the door body 500. The adhesive can be a liquid self-drying adhesive, or common adhesive products such as double-sided tape can be used.
[0039] As Figure 3 shown, a through groove is provided on the connecting plate 310, and the second magnetic member 400 is embedded in the through groove. The thickness of the connecting plate 310 can be further thinned to reduce the occupied space after installation, especially to avoid affecting the opening and closing of the door.
[0040] As Figure 3 shown, the second locking portion 330 includes a locking rib 332 formed by a protrusion at the bottom of the connecting plate 310, and the locking rib 332 is located on the side of the second magnetic member 400 away from the limiting rib 320;
[0041] The second locking portion 330 includes a silent elastic member 331, and at least part of the silent elastic member 331 is arranged on the side of the locking rib 332 close to the limiting rib 320;
[0042] When the first locking portion 210 and the second locking portion 330 form a cooperation, the first locking portion 210 abuts against the silent elastic member 331. When the first locking portion 210 and the second locking portion 330 collide to form an abutting cooperation, the silent elastic member 331 can play a role in silent anti-collision and noise reduction.
[0043] Further, the sound - proof elastic member 331 is an annular member. The sound - proof elastic member 331 is sleeved outside the locking rib 332. The cross - section of the locking rib 332 is T - shaped. A limiting groove is formed between the locking rib 332 and the bottom surface of the connecting plate 310. The sound - proof elastic member 331 is embedded in the limiting groove. With such a setting, the sound - proof elastic member 331 is convenient to install and can be reliably fixed at the same time. In this embodiment, the sound - proof elastic member 331 is specifically a high - elastic rubber ring.
[0044] As Figure 2 shown, a plurality of grooves 311 are provided on the upper surface of the connecting plate 310. The setting of the grooves 311 can increase the contact area between the glue and the upper surface of the connecting plate 310, which is beneficial to the adhesion and distribution of the glue, increases the mechanical interlocking effect of the glue, and enhances the bonding effect.
[0045] The moving mode of the first magnetic attraction member 200 relative to the bottom plate 100 can be rotation or up - and - down lifting. In this embodiment, the first magnetic attraction member 200 is rotatable relative to the bottom plate 100. Specifically, as Figure 7 shown, two protrusions are formed on both sides of one end of the first magnetic attraction member 200 to form a rotating shaft 220; as Figure 6 shown, the bottom plate 100 is provided with two oppositely - arranged connecting side plates 110 and an intermediate plate 120 connected between the two side plates 110 and extending outward relative to the connecting side plates 110. A fitting groove 111 is formed on the inner side of the side plate 110. The rotating shaft 220 is rotatably located in the fitting groove 111. The intermediate plate 120 is located below the first magnetic attraction member 200 to form a limit for the first magnetic attraction member 200.
[0046] Further, a protective rib 121 is formed on the outer periphery of the upper end of the intermediate plate 120, and the height of the protective rib 121 is adapted to the thickness of the first magnetic attraction member 200. In the absence of magnetic attraction, the first magnetic attraction member 200 fits against the intermediate plate 120 and is located within the protective rib 121; with such a setting, in the normal state (i.e., the state where magnetic attraction adsorption is not turned on), as Figure 4 shown, the first magnetic attraction member 200 fits against the intermediate plate 120, and the protective rib 121 surrounds the first magnetic attraction member 200, which can prevent the first magnetic attraction member 200 from being kicked by people and thus being damaged. At this time, the height of the connecting side plate 110 is higher than that of the protective rib 121, and the upper end surface of the connecting side plate 110 and the upper end surface of the protective rib 121 are in a smooth - curved - surface transition. In this way, even if it is stepped on, no obvious discomfort will be generated.
[0047] The rear ends of the two connecting side plates 110 are connected by a back plate 140. The lower end of the fitting groove 111 is open. A through groove 130 for the installation and protrusion of the first magnetic member 200 is formed between the connecting side plates 110, the back plate 140 and the middle plate 120. With such a setting, the assembly of the first magnetic member 200 and the bottom plate 100 is convenient. During assembly, the first magnetic member 200 is held vertically upward, passed through the through groove 130 from the bottom, the rotating shaft 220 is inserted into the fitting groove 111 from the bottom opening, and then rotated to make the first magnetic member 200 fit the middle plate 120, and the installation can be completed.
[0048] Furthermore, the middle plate 120 is provided with mounting holes 122 for the installation of bolts. The base part of this embodiment can be installed by bonding or fixed by bolts, which is selected according to the material of the specific installation ground. For example, for floors made of materials such as tiles and marble, bolt fixation is not applicable, and bonding can be used for installation, that is, in combination with waterproof double-sided tape, etc., for installation.
[0049] Furthermore, the bottom plate 100 further includes a heightening member 150. When the distance between the ground where the base part is installed and the bottom surface of the door where the suction seat part is installed varies greatly, the first magnetic member 200 and the second magnetic member 400 may not be able to form a normal magnetic attraction. This embodiment provides a heightening member 150 that is separately provided from the bottom plate 100, which is specifically selected according to the installation situation. For example, when this embodiment is installed on an inward-opening bathroom door, in order to avoid water overflow, the bathroom floor is usually set lower than the outside floor. Therefore, there is usually a large difference in the distance between the inward-opening bathroom door and the bathroom floor, and then, as Figure 9 shown, one heightening member 150 or a combination of multiple stacked heightening members 150 can be selected for compensation.
[0050] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
