Description

Technical Field

[0001] This utility model relates to the field of door catch technology, and in particular to a two-stage force door catch base and door catch. Background Technology

[0002] A door catcher is a hardware component used for controlling the opening and closing of doors. It consists of a magnet base and a base. Its core function is to fix the door in place by magnetic attraction, ensuring that the door remains open and preventing it from closing on its own due to wind or inertia.

[0003] Currently, in the use of door catchers, the magnet base is installed below the door, and the base is installed on the ground. The magnet base contains a magnet, and a movable metal plate is rotatably mounted on the base. When the door is opened, the base is above the metal plate, and the metal plate is lifted by magnetic force, forming an adsorption effect with the magnet base. Since the base is installed on the ground, when the door is closed, the metal plate needs to be hidden inside the base as much as possible to avoid bumping into pedestrians. Therefore, the metal plate has a thin sheet structure, with one end rotatably assembled with the base and the other end magnetically adsorbed with the magnet base.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the metal sheet and the magnet are in line contact, the contact area is small, and the adsorption effect is poor. In actual use, the metal sheet is prone to detaching from the magnet base, which may lead to the risk of the door accidentally closing and hitting the door frame. The impact sound may frighten people, and the accidental closing of the door may accidentally injure people, posing certain safety hazards. Utility Model Content

[0005] In order to increase the adsorption area between the metal sheet and the magnet base, and to improve the adsorption stability and reliability of the door catcher on the door, this application provides a two-stage force door catcher base and door catcher.

[0006] Firstly, the present invention provides a two-section force-operated door suction base, which adopts the following technical solution:

[0007] A two-stage force-assisted suction base includes a movable component and a fixed component for mounting on the ground. The movable component includes a rotating plate and an adsorption plate. One end of the rotating plate is rotatably assembled with the fixed component, and the adsorption plate is movably assembled with the other end of the rotating plate.

[0008] Preferably, it further includes a connecting piece for rotatably assembling the adsorption piece and the rotating piece.

[0009] Preferably, the connecting piece is provided with a hook, and the adsorption piece and / or the rotating piece are provided with through holes for rotatable assembly with the hook.

[0010] Preferably, the connecting piece has hooks at both ends, namely a first hook and a second hook, the adsorption piece has a first through hole for rotatably assembling with the first hook, and the rotating piece has a second through hole for rotatably assembling with the second hook.

[0011] Preferably, the first hook and the second hook are provided with extensions that protrude in a direction toward each other.

[0012] Preferably, the length of the adsorption plate is less than the length of the rotating plate.

[0013] Preferably, the fixing member has a receiving cavity for accommodating the movable member, the end of the adsorption plate away from the rotating plate is arc-shaped, the side wall of the receiving cavity is provided with an arc-shaped portion corresponding to the adsorption plate, and the arc-shaped portion is gradually inclined and contracted from top to bottom.

[0014] Preferably, the rotating plate has lugs on both sides of the end away from the adsorption plate, the bottom wall of the receiving cavity has a rotating groove for rotating assembly with the lugs, and the rotating plate has a curved part that is curved toward the rotating groove.

[0015] Secondly, the two-stage force-operated door catch provided by this utility model adopts the following technical solution:

[0016] A two-stage force-operated door catcher includes the aforementioned two-stage force-operated door catcher base and a magnet base. A magnet is embedded in the bottom of the magnet base, and a limiting part is provided on the bottom wall of the magnet base facing downward. When the adsorption sheet is adsorbed onto the bottom wall of the magnet base, the side wall of the adsorption sheet contacts the limiting part.

[0017] Preferably, the limiting part has a triangular cross-section and an inclined part is provided on the side wall of the limiting part near the magnet. The inclined part is gradually inclined and narrows from bottom to top.

[0018] The beneficial effects of this utility model are as follows:

[0019] By employing a two-section structure of rotating plate and adsorption plate, when the door is opened, the moving part is attracted by the magnet of the magnet base and rotates. The first section is the inclined section formed after the rotating plate and the fixed part rotate. The second section is the horizontal section formed after the adsorption plate and the rotating plate rotate and are magnetically attracted to the magnet base. The moving part and the magnet base are in surface contact, which greatly increases the adsorption area and thus significantly improves the adsorption force. This makes the door more stable when it is open, effectively preventing accidental detachment due to wind, human collision, etc., avoiding accidental closure of the door, and improving the safety of use.

[0020] By incorporating a connecting piece, which acts as a bridge between the adsorption plate and the rotating plate during rotational assembly, the connection between the two is strengthened. Compared to directly connecting the adsorption plate and the rotating plate, the connecting piece can provide a larger contact area and a more stable rotational structure, thereby improving the overall structural reliability and preventing loosening or detachment due to long-term use. Secondly, when the door is subjected to external forces, the connecting piece can buffer and disperse stress, preventing excessive stress concentration on a certain part of the adsorption plate or rotating plate, thereby reducing wear and deformation and extending the service life of the door catch.

[0021] By setting a limiting part in the magnet base, the lateral movement of the adsorption sheet is effectively prevented in the adsorption state. When the side wall of the adsorption sheet comes into contact with the limiting part, the limiting part can limit the adsorption sheet, ensuring that the adsorption sheet is firmly adsorbed on the bottom wall of the magnet base. Even when the door is subjected to external force, it can maintain a stable adsorption state and avoid the occurrence of detachment. Attached Figure Description

[0038] This section will describe in detail the specific embodiments of this application. Preferred embodiments of this application are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so as to intuitively and vividly understand each technical feature and overall technical solution of this application, but they should not be construed as limiting the scope of protection of this application.

When a feature is referred to as "set," "fixed," or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.

[0040] In the description of this application, the term "several" means one or more, and "more than" means two or more. The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number, while "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features and not as indicating or implying relative importance, the number of indicated technical features, or the order of the indicated technical features.

[0041] Furthermore, unless otherwise defined, the technical and scientific terms used in this application have the same meanings as commonly understood by one of ordinary skill in the art. The terminology used in this application is for the purpose of describing particular embodiments only and not for limiting the application. It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof.

[0042] Example 1: As Figure 1-10 As shown, a two-stage door suction base 5 includes a movable part 1 and a fixed part 2 for mounting on the ground. The movable part 1 includes a rotating plate 101 and an adsorption plate 102. One end of the rotating plate 101 is rotatably mounted to the fixed part 2, and the adsorption plate 102 is movably mounted to the other end of the rotating plate 101. By adopting a two-stage structure of rotating plate 101 and adsorption plate 102, when the door is opened, the movable part 1 is attracted and rotated by the magnet 601 of the magnet base 6. The first stage of force is the inclined stage formed after the rotating plate 101 and the fixed part 2 rotate. The second stage of force is the horizontal stage formed after the adsorption plate 102 and the rotating plate 101 rotate and are magnetically attracted to the magnet base 6. The movable part 1 and the magnet base 6 are in surface contact, which greatly increases the adsorption area and thus significantly improves the adsorption force. This makes the door more stable when it is open, effectively preventing accidental detachment due to wind, human collision, etc., avoiding accidental closure of the door, and improving the safety of use.

[0043] It is worth mentioning that the adsorption plate 102 is made of magnetic material, such as iron. Of course, the rotating plate 101 can be made of non-magnetic material, which can improve the design diversity of the moving part 1. Furthermore, the rotating plate 101 can be made of lightweight material, such as plastic, to reduce the weight of the base 5. Secondly, since the adsorption area is larger than that of the existing line contact, the art has the ability and motivation to ensure that the force of separation between the door and the door suction when the door is closed is not too large and affects the feel by selecting different types of magnetic materials.

[0044] Regarding the specific structure of the movable assembly of the adsorption plate 102 and the rotating plate 101, this embodiment also includes a connecting plate 3. The connecting plate 3 is used for the rotatable assembly of the adsorption plate 102 and the rotating plate 101. As a bridge for the rotatable assembly between the adsorption plate 102 and the rotating plate 101, the connecting plate 3 can enhance the connection between the two. Compared with directly connecting the adsorption plate 102 and the rotating plate 101, the connecting plate 3 can provide a larger contact area and a more stable rotation structure, thereby improving the reliability of the overall structure and avoiding loosening or falling off due to long-term use. Secondly, when the door is subjected to external force, the connecting plate 3 can play a role in buffering and dispersing stress, avoiding excessive stress concentration in a certain part of the adsorption plate 102 or the rotating plate 101, thereby reducing wear and deformation and extending the service life of the door catch.

[0045] Regarding the assembly structure between the connecting piece 3 and the adsorption piece 102 and the rotating piece 101, the connecting piece 3 is provided with a hook, and the adsorption piece 102 and / or the rotating piece 101 are provided with through holes for rotating assembly with the hook. Since the adsorption piece 102 and / or the rotating piece 101 are provided with through holes, one or more hooks are provided correspondingly and located in the through holes, and are movably hooked on the side wall of the through holes, thereby forming a rotating connection structure to realize the rotating assembly of the adsorption piece 102 and the rotating piece 101.

[0046] In one embodiment, the connecting piece 3 has two sets of hooks at both ends. The adsorption piece 102 and the rotating piece 101 are both provided with through holes for rotating assembly with the hooks. The through holes of the adsorption piece 102 and the rotating piece 101 are close to each other. The through holes of the adsorption piece 102 are rotatably assembled with one set of hooks of the connecting piece 3, and the through holes of the rotating piece 101 are rotatably assembled with the other set of hooks of the connecting piece 3, so that the adsorption piece 102 and the rotating piece 101 can rotate independently, realizing flexible two-stage rotation.

[0047] In another embodiment, one end of the connecting piece 3 is provided with a hook, and the adsorption piece 102 is provided with a through hole for rotating assembly with the hook. The through hole of the adsorption piece 102 is rotatably assembled with the hook of the connecting piece 3, and the end of the connector away from the hook is connected to the connecting piece 3. In this case, the rotating piece 101 does not need to be provided with a through hole, the structure is simpler, and the processing cost is lower.

[0048] In another embodiment, one end of the connecting piece 3 is provided with a hook, and the rotating piece 101 is provided with a through hole for rotating assembly with the hook. The through hole of the rotating piece 101 is rotatably assembled with the hook of the connecting piece 3, and the end of the connector away from the hook is connected to the adsorption piece 102. In this case, the adsorption piece 102 is directly fixed to the connecting piece 3, and the force is more direct.

[0049] Specifically, hooks are provided at both ends of the connecting piece 3, namely a first hook 301 and a second hook 302. The adsorption piece 102 has a first through hole 1021 for rotating assembly with the first hook 301, and the rotating piece 101 has a second through hole 1011 for rotating assembly with the second hook 302. The dual-section design greatly improves the overall adjustment range of the door catcher, which can better adapt to doors with different opening angles and different installation positions, and enhances the versatility and adaptability of the door catcher.

[0050] It should be noted that the hook portion includes a first hook portion 301 and a second hook portion 302, and the through hole includes a first through hole 1021 and a second through hole 1011.

[0051] To improve the smoothness of rotation between the hook and the inner wall of the through hole, the inner wall of the hook is designed in an arc shape. Preferably, the inner wall of the hook is designed in a semi-circular shape. Of course, the inner wall of the through hole can also be designed in a matching arc shape to reduce the coefficient of friction between the two, reduce friction, make rotation easier and smoother, and improve rotation efficiency.

[0052] Regarding the design of the mating structure between the movable piece and the connecting piece 3, the inner diameter of the hook is 1.2 to 1.4 times the thickness of the movable part 1. The adsorption piece 102 and the rotating piece 101 are spaced apart, and the distance between the adsorption piece 102 and the rotating piece 101 is 1.1 to 1.2 times the thickness of the movable part 1. The width of the first through hole 1021 is 1.8 to 1.9 times the thickness of the movable part 1. The distance between the inner wall of the first through hole 1021 and the side wall of the adsorption piece 102 near the rotating piece 101 is 1.1 to 1.2 times the thickness of the movable part 1. The width of the second through hole 1011 is 1.4 to 1.6 times the thickness of the movable part 1. The distance between the inner wall of the second through hole 1011 and the side wall of the rotating piece 101 near the adsorption piece 102 is 1.4 to 1.5 times the thickness of the movable part 1, thereby ensuring smooth rotation between the adsorption piece 102 and the rotating piece 101.

[0053] In one embodiment, the thickness of the movable part 1 is 1.15 mm, the inner diameter of the hook is 1.5 mm, the gap between the adsorption plate 102 and the rotating plate 101 is 1 mm, the width of the first through hole 1021 is 2.15 mm, the distance between the inner wall of the first through hole 1021 and the side wall of the adsorption plate 102 near the rotating plate 101 is 1 mm, the width of the second through hole 1011 is 1.5 mm, and the distance between the inner wall of the second through hole 1011 and the side wall of the rotating plate 101 near the adsorption plate 102 is 1.65 mm.

[0054] To prevent the adsorption plate 102 and / or the rotating plate 101 from falling off the connecting plate 3 during rotation, the first hook 301 and the second hook 302 are provided with protruding extensions 303 close to each other. The extensions 303 form a mechanical anti-fall structure. By designing the inner wall diameter of the hook and the thickness of the moving part 1, the extensions 303 will not interfere when the adsorption plate 102 or the rotating plate 101 is within the normal rotation range, thereby effectively preventing falling off.

[0055] To ensure the adsorption area between the adsorption plate 102 and the magnet base 6, the length of the adsorption plate 102 is less than the length of the rotating plate 101. Preferably, the length of the adsorption plate 102 is 0.65 to 0.75 times the length of the rotating plate 101, and more preferably 0.75 times. This ensures the adsorption force while avoiding problems such as inflexible rotation and limited installation space caused by an excessively large adsorption plate 102.

[0056] To ensure that the movable component 1 is concealed within the fixed component 2 when the door is opened, the fixed component 2 has a receiving cavity 201 for accommodating the movable component 1. The end of the suction plate 102 away from the rotating plate 101 is arc-shaped, and the side wall of the receiving cavity 201 has an arc-shaped portion 2011 corresponding to the suction plate 102. The arc-shaped portion 2011 gradually slopes and tapers from top to bottom. When the door is opened, the movable component 1 is retracted into the receiving cavity 201 inside the fixed component 2, thus achieving a concealed effect. This design allows the door catcher to remain concealed when the door is open. The door is not exposed in the open, maintaining the overall aesthetics of the door and its surroundings. Secondly, the end of the adsorption plate 102 away from the rotating plate 101 is designed as an arc, and the side wall of the receiving cavity 201 is also correspondingly provided with an arc-shaped part 2011. The arc-shaped part 2011 gradually slopes and tapers from top to bottom. This design allows the adsorption plate 102 to slide smoothly into the receiving cavity 201 along the arc-shaped part 2011 during storage, which plays a guiding role and avoids the adsorption plate 102 from getting stuck or scratched during storage, ensuring the smooth storage of the moving part 1.

[0057] Regarding the rotating assembly structure of the rotating plate 101 and the fixing member 2, the two side walls of the rotating plate 101 away from the adsorption plate 102 are respectively provided with lugs 1012. The bottom wall of the receiving cavity 201 is provided with a rotating groove 2012 that is rotatably assembled with the lugs 1012. The rotating plate 101 is curved in an arc shape towards the rotating groove 2012 and is provided with a bending part 1013. The cooperation between the lugs 1012 and the rotating groove 2012 makes the rotation of the rotating plate 101 more stable. The arc design of the bending part 1013 avoids the risk of interference between the rotating plate 101 and the inner wall of the rotating groove 2012, ensuring the smoothness and stability of the rotation of the rotating plate 101.

[0058] To prevent the movable piece from slipping off the fixing part 2 during transportation, this embodiment also includes a cover plate 4. The bottom wall of the fixing part 2 is recessed towards the rotating groove 2012 and a groove is provided. The cover plate 4 is placed on the top wall of the groove and the cover plate 4 is connected to the top wall of the groove by screws.

[0059] Regarding the specific structure of the fastener 2 being assembled with the ground, the bottom wall of the receiving cavity 201 is provided with a connecting hole, which is used for screws to pass through and for mounting the fastener 2 on the ground.

[0060] Example 2: Figure 1-15 As shown, a two-stage force-operated door catcher includes a two-stage force-operated door catcher base 5 as described in Embodiment 1, and a magnet base 6. A magnet 601 is embedded in the bottom of the magnet base 6. A limiting part 602 is provided with a downward protrusion on the bottom wall of the magnet base 6. When the adsorption piece 102 is adsorbed onto the bottom wall of the magnet base 6, the side wall of the adsorption piece 102 contacts the limiting part 602. The limiting part 602 can prevent the adsorption piece 102 from moving laterally in the adsorption state. When the side wall of the adsorption piece 102 contacts the limiting part 602, the limiting part 602 can limit the adsorption piece 102, ensuring that the adsorption piece 102 is firmly adsorbed onto the bottom wall of the magnet base 6. Even when the door is subjected to external force, it can maintain a stable adsorption state and avoid the occurrence of detachment.

[0061] In order for the magnet base 6 to magnetically adsorb the adsorption piece 102, the limiting part 602 can play a certain degree of limiting and guiding role. The cross-section of the limiting part 602 is designed with a triangular structure. The side wall of the limiting part 602 near the magnet 601 is provided with an inclined part. The inclined part is gradually inclined and contracted from bottom to top. Through the limiting part 602 with triangular cross-section, in conjunction with the inclined part that gradually inclines and contracts from bottom to top, the adsorption piece 102 can be guided to be accurately positioned when it approaches and is adsorbed to the magnet base 6. This ensures that the adsorption piece 102 can be adsorbed in the correct position and angle every time, thereby improving the reliability and stability of adsorption.

[0062] Regarding the specific structure of the assembly of magnet 601 and magnet base 6, magnet 601 is cylindrical, and the bottom wall of magnet base 6 is provided with a mounting groove for assembling magnet 601, and magnet 601 is embedded in the inner wall of the mounting groove.

[0063] In order to make the magnet base 6 concealed when installed with the door, the magnet base 6 is L-shaped and has a vertical section and a horizontal section, so as to fit the side wall and bottom wall of the door. The limiting part 602 is located in the horizontal section of the magnet, and the limiting seat is located at the end closer to the water pair section and away from the vertical section.

[0064] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
