Description

Technical Field

[0001] This utility model relates to a floor-mounted door catch device. Background Technology

[0002] In the existing technology, door catches are generally divided into floor-mounted and wall-mounted types. Floor-mounted door catches generally include a base plate fixed to the ground, with an iron plate that can swing up and down on the base plate. The bottom surface of the door leaf is provided with a positioning seat that cooperates with the iron plate. The positioning seat has a magnet for attracting the iron plate. The magnet is used to attract the iron plate so that the end of the iron plate abuts against a specific position of the positioning seat.

[0003] However, the metal sheet that is attracted is tilted upward relative to the ground, and only the end of the metal sheet contacts the positioning seat, resulting in very little contact area. Especially when the gap between the door leaf and the ground is large, the metal sheet and the positioning seat can only form a line contact, which makes the stability of the magnetically fixed door panel very poor. The door leaf will rotate if blown by the wind or touched by clothing. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a floor-mounted door catch device that can increase the adsorption area between the magnetic plate and the magnet to improve the stability of door positioning.

[0005] A floor-mounted door catch device according to an embodiment of the present invention includes: a mounting base for fixing to the bottom of a door leaf, the mounting base having a flat plate portion located on the lower surface of the door leaf, the flat plate portion having a magnet; a base for fixing to the ground, the base being movably connected to a swing arm that can swing up and down relative to it, the end of the swing arm being rotatably provided with a magnetic suction plate, the magnetic suction plate being attracted by the magnet to be able to flatly adhere to the lower surface of the flat plate portion, the magnetic suction plate and the swing arm being able to retract to the base under the action of gravity.

[0006] The floor-mounted door catch device according to an embodiment of the present invention has at least the following features:

[0007] Beneficial effects:

[0008] When the door moves to a position where the flat section is above the magnetic plate, the magnet attracts the magnetic plate, causing the swing arm to swing upwards. During this upward swing, the magnetic plate is subjected to a vertical magnetic force and rotates relative to the swing arm to maintain a horizontal position. When the magnetic plate rests against the flat section, it lies flat against the lower surface of the flat section, increasing the contact area between the magnetic plate and the magnet. This provides a greater magnetic force to the door and improves the stability of positioning the door. Regardless of the swing arm's angle, the magnetic plate remains horizontal, suitable for different gaps between the door and the ground. When the door moves to a position where the magnet is no longer above the magnetic plate, the magnetic plate and swing arm fall onto the base under their own weight, preventing users from easily kicking them and getting injured.

[0009] In some embodiments of this utility model, one end of the swing arm is rotatably connected to the base via a first horizontal pivot, and the magnetic plate is rotatably connected to the other end of the swing arm via a second horizontal pivot.

[0010] In some embodiments of this utility model, the upper surface of the base is recessed into a groove, and part or all of the magnetic plate and the swing arm can be accommodated in the groove.

[0011] In some embodiments of this utility model, the sink is rectangular, the swing arm is a rectangular plate, and the width of the magnetic plate, the rectangular plate and the sink are the same. When the magnetic plate and the rectangular plate are accommodated in the sink, the magnetic plate and the rectangular plate do not protrude from the upper surface of the base.

[0012] In some embodiments of this utility model, the first horizontal pivot is formed at one end of the rectangular plate, and the two ends of the first horizontal pivot protrude from both sides of the width direction of the rectangular plate. One end of the base is provided with a long strip through hole that communicates with the sink groove. The long strip through hole allows the rectangular plate to pass through and accommodate the first horizontal pivot. At the junction between the long strip through hole and the sink groove, there is an arc-shaped shaft hole that matches the two ends of the first horizontal pivot.

[0013] In some embodiments of this utility model, one end of the rectangular plate is provided with a curved plate portion intersecting therewith, the first horizontal pivot is formed in the curved plate portion, and an obtuse angle region with an opening facing downward is formed between the curved plate portion and the rectangular plate. The obtuse angle region is used to avoid the edge line of the bottom of the sinking trough intersecting with the elongated perforation.

[0014] In some embodiments of this utility model, the rectangular plate is provided with two side ears at intervals at one end near the magnetic plate, and the two side ears are provided with a first through hole. The magnetic plate has a convex ear located between the two side ears, and the convex ear is provided with a second through hole opposite to the first through hole. The second horizontal pivot passes through the first through hole and the second through hole.

[0015] In some embodiments of this utility model, both the rectangular plate and the magnetic plate are made of iron.

[0016] In some embodiments of this utility model, the flat plate portion is provided with a downward-facing mounting hole, the mounting hole matching the outline shape of the magnet, and the lower surface of the magnet being flush with the lower surface of the flat plate portion.

[0017] In some embodiments of this utility model, the mounting base further includes a fixing plate and a stop plate respectively formed at both ends of the flat plate portion. The fixing plate extends upward to abut against the side wall of the door leaf, and the stop plate bends downward to abut against the side of the magnetic plate.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] See Figures 1 to 3 This utility model discloses a floor-mounted door catch device, comprising: a mounting base 100 for fixing to the bottom of a door leaf 10, the mounting base 100 having a flat plate portion 110 located on the lower surface of the door leaf 10, the flat plate portion 110 having a magnet 200; a base 300 for fixing to the ground, the base 300 being movably connected to a swing arm that can swing up and down relative to it, the end of the swing arm being rotatably provided with a magnetic suction plate 500, the magnetic suction plate 500 being attracted by the magnet 200 to be able to flatly adhere to the lower surface of the flat plate portion 110, the magnetic suction plate 500 and the swing arm being able to retract to the base 300 under the action of gravity.

[0030] When the door leaf 10 moves to a position where the flat plate 110 is above the magnetic suction plate 500, the magnet 200 attracts the magnetic suction plate 500, causing the swing arm to swing upward. During the upward swing of the swing arm, the magnetic suction plate 500 is subjected to a vertical magnetic force and rotates relative to the swing arm to maintain a horizontal state. When the magnetic suction plate 500 abuts against the flat plate 110, it lies flat against the lower surface of the flat plate 110, thereby increasing the contact area between the magnetic suction plate 500 and the magnet 200, thus providing a greater magnetic force to the door leaf 10 and improving the stability of positioning the door leaf 10. No matter what angle the swing arm swings to, the magnetic suction plate 500 always remains horizontal, suitable for different door gap distances between the door leaf 10 and the ground. When the door leaf 10 moves to a position where the magnet 200 leaves the magnetic suction plate 500, the magnetic suction plate 500 and the swing arm fall onto the base 300 due to their own gravity, preventing users from easily kicking the magnetic suction plate 500 and the swing arm and getting injured.

[0031] See Figure 1 and Figure 2 In some embodiments of this utility model, in order to achieve smooth and stable up-and-down swinging of the swing arm relative to the base 300, one end of the swing arm is rotatably connected to the base 300 via a first horizontal pivot 600, and the magnetic plate 500 is rotatably connected to the other end of the swing arm via a second horizontal pivot 700. When the magnetic plate 500 rotates relative to the swing arm around the second horizontal pivot 700, it is always parallel to the base 300.

[0032] See Figure 2 In some embodiments of this utility model, the upper surface of the base 300 is recessed into a groove 310, and part or all of the magnetic suction plate 500 and the swing arm can be accommodated within the groove 310. It is understood that when the magnetic suction plate 500 is not attracted by the magnet 200, at least a portion of the magnetic suction plate 500 and the swing arm are located within the groove 310, thereby reducing the height of the floor-mounted door catch protruding from the ground, reducing the possibility of injury to the user from touching it, and also facilitating the passage of other items across the ground.

[0033] See Figure 2 In some embodiments of this utility model, the sink 310 is rectangular, the swing arm is a rectangular plate 400, and the width dimensions of the magnetic plate 500, the rectangular plate 400, and the sink 310 are consistent. This makes the overall shape of the magnetic plate 500, the rectangular plate 400, and the base 300 more regular, and the structure more compact when the magnetic plate 500 is not attracted by the magnet 200, reducing the possibility of dirt accumulation. Furthermore, when the magnetic plate 500 and the rectangular plate 400 are housed within the sink 310, they do not protrude from the upper surface of the base 300, further improving the structural compactness.

[0034] See Figure 2 and Figure 3 In some embodiments of this utility model, the first horizontal pivot 600 is formed on one end of the rectangular plate 400, and the two ends of the first horizontal pivot 600 protrude from both sides of the rectangular plate 400 in the width direction. One end of the base 300 is provided with a long through hole 320 that communicates with the recess 310. The long through hole 320 allows the rectangular plate 400 to pass through and accommodate the first horizontal pivot 600. At the junction between the long through hole 320 and the recess 310, there is an arc-shaped shaft hole 321 that matches the two ends of the first horizontal pivot 600. It should be noted that when the swing arm is assembled onto the base 300, the rectangular plate 400 is passed through the elongated through hole 320 from the bottom of the base 300 so that the rectangular plate 400 is positioned above the recess 310. At this time, the two ends of the first horizontal pivot 600 abut against the arc-shaped shaft hole 321 respectively, preventing the first horizontal pivot 600 from detaching from the elongated through hole 320. Since the base 300 is fixed on the ground, that is, the ground is directly opposite the arc-shaped shaft hole 321, preventing the first horizontal pivot 600 from detaching from the base 300.

[0035] See Figure 2 and Figure 3 In some embodiments of this utility model, one end of the rectangular plate 400 is provided with a curved plate portion 410 intersecting therewith. The first horizontal pivot 600 is formed in the curved plate portion 410. An obtuse angle region 420 with an opening facing downward is formed between the curved plate portion 410 and the rectangular plate 400. The obtuse angle region 420 is used to avoid the edge line where the bottom of the sink 310 intersects with the elongated perforation 320, so that when the rectangular plate 400 rotates around the first horizontal pivot 600 to abut against the sink 310, it will not interfere with the aforementioned edge line. The obtuse angle region 420 plays a role in avoiding interference, ensuring that the rectangular plate 400 can be accommodated within the sink 310.

[0036] See Figure 2 In some embodiments of this utility model, the rectangular plate 400 is provided with two side ears 430 at intervals near one end of the magnetic suction plate 500. A first through hole 431 is provided through each of the two side ears 430. The magnetic suction plate 500 has a protruding ear 510 located between the two side ears 430. A second through hole 520 is provided through the protruding ear 510 opposite to the first through hole 431. A second horizontal pivot 700 passes through the first through hole 431 and the second through hole 520. The second horizontal pivot 700 is a pin that is tightly fitted with the first through hole 431 and / or the second through hole 520 to prevent the pin from disengaging axially.

[0037] In some embodiments of this utility model, both the rectangular plate 400 and the magnetic plate 500 are made of iron. It is understood that the cost of making both the rectangular plate 400 and the magnetic plate 500 from iron is low. Correspondingly, the magnet 200 is a magnet, ensuring the swing arm has high mechanical strength, which helps extend its service life, and the attraction force between the swing arm and the magnet 200 is relatively strong.

[0038] See Figure 2 In some embodiments of this utility model, in order to facilitate the installation and fixation of the magnet 200 while ensuring the force exerted by the magnet 200 on the magnetic suction plate 500, the flat plate portion 110 is provided with a downward-facing mounting hole 111. The mounting hole 111 matches the contour shape of the magnet 200, and the lower surface of the magnet 200 is flush with the lower surface of the flat plate portion 110. The magnet 200 can be fixed in the mounting hole 111 using glue or by tightly fitting the magnet 200 into the mounting hole 111.

[0039] See Figure 1 and Figure 2 In some embodiments of this utility model, the mounting base 100 further includes a fixing plate 120 and a stop plate 130 respectively formed at both ends of the flat plate portion 110. The fixing plate 120 extends upward to abut against the side wall of the door leaf 10, and the stop plate 130 is bent downward to abut against the side of the magnetic suction plate 500. Specifically, the fixing plate 120 is fixed to the side wall of the door leaf 10 using glue or fastening screws. When the magnetic suction plate 500 is attracted by the magnet 200 and abuts against the flat plate portion 110, as the opening angle of the door leaf 10 further opens, the magnetic suction plate 500 abuts against the stop plate 130, thus limiting the maximum opening angle of the door leaf 10.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
