Description

Technical Field

[0001] This utility model relates to the field of door catch technology, and in particular to a silent door catch with a snap-fit ​​mechanism. Background Technology

[0002] A floor door catcher, also called a floor door catcher or ground door catcher, is a door fixing device installed on the ground. It is mainly used to attract and fix the door leaf in the open state, preventing the door from closing automatically due to wind, gravity or accidental contact. It is commonly used in homes, hotels, office buildings, shops and other places.

[0003] Traditional door catchers typically consist of a door catcher mounting bracket, a base, a magnet, and a suction plate. In use, the door catcher mounting bracket is installed on the outside of the door, and the base is installed on the ground. When the door is opened, the door catcher mounting bracket approaches the base, and the magnet attracts the suction plate, thus opening the door. When the door is closed, when the magnet is too far away from the base, the suction plate falls back to the base under the influence of gravity.

[0004] However, traditional door stoppers lack a sound-dampening structure, causing the suction plate to fall and contact the base under gravity when the door is closed, generating significant impact noise. At the same time, frequent impacts accelerate wear between the suction plate and the base, thus reducing the lifespan of the door stopper and the user experience. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a door catcher with a snap-fit ​​function, which aims to improve the problem that traditional door catchers lack a sound-absorbing structure during use, resulting in significant impact noise when the door is closed as the suction plate falls and contacts the base under gravity.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A silent doorstop with a snap-on mechanism includes:

[0008] A door catch mount, which is installed on the outside of a room door;

[0009] A base, which is mounted on the ground;

[0010] A suction plate, which is rotatably connected inside the base;

[0011] A sound-absorbing pad is disposed in the middle of the base, and the sound-absorbing pad is made of rubber.

[0012] The protrusions are fixedly connected to both sides of the bottom of the sound-absorbing pad.

[0013] Furthermore, a magnet is installed at the bottom of the door catch mounting component, and a U-shaped buckle is fixedly connected to the lower left side of the door catch mounting component. The U-shaped buckle is made of rubber.

[0014] Furthermore, mounting holes are provided on all four sides of the outside of the door catch mounting component.

[0015] Furthermore, the base has connection holes on both sides inside, and the two protrusions are inserted into the two connection holes.

[0016] Furthermore, positioning holes are provided on both sides of the interior of the base.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, during installation, the door catcher is first fixed to the outside of the door, the base is fixed to the ground, the suction plate is rotated to a vertical position to expose the inside of the base, the two protrusions at the bottom of the sound-absorbing pad are aligned with the two mounting holes in the middle of the base and inserted, when the door is opened, the magnet pulls up the suction plate so that it fits against the magnet, the U-shaped buckle fixes the top of the suction plate to enhance its firmness, when the door is closed, the suction plate is released from the magnetic force and falls, the rubber sound-absorbing pad buffers the impact force, reduces noise and extends service life.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 This utility model provides an embodiment of a silent door catcher with a snap-fit ​​mechanism, comprising: a door catcher mounting component 1, installed on the outside of a door; a base 5, installed on the ground; a suction plate 6, rotatably connected to the inside of the base 5; a sound-absorbing pad 8, located in the middle of the base 5, the sound-absorbing pad 8 being made of rubber; capable of absorbing the impact and vibration noise when opening and closing the door, reducing noise from metal collisions; protrusions 9, fixedly connected to the bottom sides of the sound-absorbing pad 8; and connecting holes 10 on both sides of the inside of the base 5, with the two protrusions 9 connected to the two connecting holes 10. The door catcher 1 has a 0-phase plug-in connection. Mounting holes 2 are provided on both sides of the outside of the door catcher 1. The mounting holes 2 facilitate the fixing of the door catcher 1 to the outside of the door. A magnet 3 is installed at the bottom inside the door catcher 1. A U-shaped buckle 4 is fixedly connected to the lower left side of the door catcher 1. The U-shaped buckle 4 is made of rubber. Rubber has a high coefficient of friction, which helps to form good friction between the U-shaped buckle 4 and the suction plate 6, preventing positional displacement or loosening due to slippage during use. Positioning holes 7 are provided on both sides of the inside of the base 5. The positioning holes 7 facilitate the fixing of the base 5 to the ground.

[0028] Specifically, when using this door catcher, firstly, the door catcher mounting part 1 needs to be firmly installed on the outside of the door at the designated position. Next, the base 5 is firmly fixed to the ground. When installing the sound-absorbing pad 8, first rotate the suction plate 6 from its original position inside the base 5 to a vertically upward position, thus fully exposing the internal space of the base 5. Then, align the two protrusions 9 fixed to the bottom of the sound-absorbing pad 8 with the two connecting holes 10 in the middle of the base 5. Then, make the protrusions 9 contact and insert them into the connecting holes 10, ensuring that the sound-absorbing pad 8 is firmly installed inside the base 5, preventing it from falling off or shifting due to vibration or impact. At this point, the installation of the sound-absorbing pad 8 is complete. When the door is opened, the door catcher mounting part 1 gradually moves closer to the base 5 on the ground as the door moves. After the distance between them shortens to a certain extent, the magnetic force generated by the magnet 3 installed on the door catcher mounting part 1 begins to take effect, causing the suction plate 6 to be attracted by the magnetic force. The suction plate 6 moves rapidly towards and adheres to the magnet 3. Simultaneously, the top of the suction plate 6 engages with the inside of the U-shaped buckle 4 located on the left side of the magnet 3, forming a multi-point positioning and stable support structure. This improves the fixing force between the suction plate 6 and the door catch mounting component 1. When the door is closed, the door catch mounting component 1 gradually moves away from the base 5. After losing the magnetic attraction of the magnet 3, the suction plate 6 automatically disengages from the constraint of the U-shaped buckle 4 and falls under the action of gravity. During the fall, the suction plate 6 uses a damping engagement between its pivot and the internal cavity of the base 5. Friction during the flipping process slows down the falling speed. This friction acts as a buffer and deceleration, reducing noise generation. Subsequently, the bottom of the suction plate 6 contacts the sound-absorbing pad 8 inside the base 5. The rubber sound-absorbing pad 8 has good elasticity and cushioning performance, absorbing the impact force generated by the fall of the suction plate 6 and preventing the suction plate 6 from colliding with the base 5, thereby reducing noise pollution and improving the comfort of the living or office environment.

[0029] Working principle: In use, first fix the door catcher 1 to the outside of the door and the base 5 to the ground. Then, when installing the sound-absorbing pad 8, first rotate the suction plate 6 to move it out of the inside of the base 5 and expose the inside of the base 5. Then, align the two protrusions 9 fixed to the bottom of the sound-absorbing pad 8 with the two connecting holes 10 in the middle of the base 5. Then insert the protrusions 9 into the connecting holes 10. At this time, the installation of the sound-absorbing pad 8 is completed. When the door is opened, when the door catcher 1 moves to one side of the base 5, the magnetic force of the magnet 3 will pull up one side of the suction plate 6, so that the top of the suction plate 6 is attached to the bottom of the magnet 3. At the same time, a U-shaped buckle 4 is installed on the left side of the magnet 3, so that the top of the suction plate 6 is locked inside the U-shaped buckle 4, which helps the door catcher to be more secure. This design reduces the likelihood of the door catcher falling off, improving its practicality. When the door is closed, the suction plate 6 disengages from the U-shaped latch 4. At this time, the suction plate 6 loses the magnetic force of the magnet 3 and falls under the influence of gravity. During the fall, the suction plate 6 is damped by the rotating shaft and the internal cavity of the base 5. Friction during the flipping process slows down the falling speed. This friction acts as a buffer and deceleration, reducing noise generation. When the suction plate 6 falls into the base 5, it comes into contact with the rubber sound-absorbing pad 8. The rubber sound-absorbing pad 8 buffers and absorbs the impact of the suction plate 6, making it easy to install the sound-absorbing pad 8 inside the door catcher base 5. The sound-absorbing pad 8 buffers and absorbs the impact of the suction plate 6, thereby reducing noise and extending service life.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
