In this embodiment, a hidden door stopper is disclosed, which comprises a top seat part 1 and a base part 2, wherein the top seat part 1 is installed in the bottom end of a door leaf in use, and the base part 2 is fixed on the ground, and when the two parts are close to each other, the two parts can be fixed together by means of magnetic attraction, so that the door leaf is fixed.

Specifically, referring to fig. 1 to 3, the top base portion 1 includes: the housing 11, the slide bar 12, the return spring 13, the first magnet 14 and the cushion 15. The housing 11 has a hollow columnar structure, and can be manufactured into a shape of a cylinder or a square column according to actual needs, and a cavity in the middle is used for accommodating other components of the top seat part 1. The slide bar 12 is slidably disposed in the housing 11, and a through hole 114 is provided at a lower end of the housing 11, so that the lower end of the slide bar 12 can be extended to the outside of the housing 11 when sliding. The return spring 13 is provided in the housing 11 and applies a force toward the upper end to the slide bar 12, and when the slide bar 12 is not subjected to an external force, the return spring 13 can move the slide bar 12 into the housing 11. The first magnet 14 and the cushion pad 15 are fixedly provided at the lower end portion of the slide bar 12, and the cushion pad 15 is located below the first magnet 14. The base part 2 has a second magnet 23 which is attracted to the first magnet 14.

The top seat part 1 in the hidden door stopper can be installed into the door leaf from the lower end surface of the door leaf, when the door leaf moves to be close to the base part 2 in use, the second magnet 23 attracts the first magnet 14, so that the sliding rod 12 can move downwards until being adsorbed on the base part 2. When the door leaf needs to be closed, after the first magnet 14 is far away from the second magnet 23, the return spring 13 can move the slide rod 12 into the shell 11. In the whole using process, the top seat part 1 in the hidden door stopper is not exposed, and the situation of scratching or stumbling of people is avoided, so that the hidden door stopper has better safety. And the base part 2 can be embedded in the ground to avoid scratching or stumbling of a person. In addition, in this embodiment, the buffer pad 15 is disposed at the lower end of the slide bar 12, so when the second magnet 23 attracts the first magnet 14, the noise can be reduced by the buffer pad 15 at the moment of the attraction of the slide bar 12 and the base portion 2, thereby avoiding the generation of relatively loud noise at the moment of the attraction of the magnets and ensuring the user to have better experience.

In this embodiment, the slide bar 12 is a hollow structure with an open upper end, and the side wall thereof is formed with a clip 122 extending inward, and the cross-sectional shape of the first magnet 14 is the same as the cross-sectional shape of the inner cavity of the slide bar 12, so that it can be inserted into the slide bar 12 from the upper end of the slide bar 12. When the first magnet 14 is inserted into the slide bar 12, the buckle 122 on the side wall of the slide bar 12 abuts against the upper end of the first magnet 14, so as to prevent the first magnet 14 from being removed from the slide bar 12.

A slider 121 is formed on the outer periphery of the slide bar 12, and a slide groove 113 through which the slider 121 can slide is formed on the inner wall of the housing 11. The slide bar 12 can be stably slid in the housing 11 by the engagement of the slide block 121 with the slide groove 113.

A plurality of limiting holes 123 penetrating the body are formed on the lower end surface of the slide bar 12, a plurality of protruding buffer parts 151 inserted into the limiting holes 123 are formed on the lower end surface of the buffer pad 15, and the lower ends of the buffer parts 151 extend to the outer sides of the limiting holes 123. In other words, the buffer pad 15 is disposed between the bottom surface of the slide bar 12 and the first magnet 14, and the buffer pad 15 may be placed inside the slide bar 12 before the first magnet 14 is mounted, and the buffer portion 151 may be inserted into the limiting hole 123. With this structure, the cushion pad 15 can be firmly attached to the slide bar 12, and the lower end can be brought into contact with the base portion 2 prior to the slide bar 12, thereby achieving a noise reduction effect. In other embodiments, the cushion pad 15 may be directly fixed to the lower end surface of the slide rod 12, for example, by bonding, screwing, or the like, and the two may be connected together to achieve the noise reduction effect.

A plurality of limit protrusions 111 are formed on the outer circumference of the housing 11, so that friction force between the top seat part 1 and the door leaf can be increased, the top seat part 1 can be firmly connected with the door leaf, and falling-off of the top seat part 1 during use is prevented. A stopper ring 112 is formed on the outer periphery of the lower end of the housing 11, and when the housing 11 is mounted, the stopper ring 112 abuts against the lower end surface of the door leaf, thereby restricting the housing 11 from moving further into the door leaf. In addition, a top cover 16 is fixedly arranged at the top end of the shell 11, so that the sliding range of the sliding rod 12 in the shell 11 can be limited, sundries can be prevented from entering the shell 11, and the normal sliding of the sliding rod 12 is influenced.

In this embodiment, the base part 2 further comprises a fixed seat 21 and a cover plate 22 fixed thereto, which can be snapped or bolted together with a cavity formed therebetween for receiving the second magnet 23. The fixing seat 21 can be directly fixed on the ground through a screw when in use, and the cover plate 22 can cover internal structures such as the screw, the second magnet 23 and the like, so that the upper end of the base part 2 has a simpler appearance, and the probability of scratching or tripping people can be reduced to a certain extent.

In this embodiment, the second magnets 23 are provided in two in total, and the two magnets are different in volume, and the second magnet is provided on the side closer to the door leaf in a smaller volume, and on the side farther from the door leaf in a larger volume. When the door leaf is gradually approaching the base part 2, the first magnet 14 is first opposite to the smaller second magnet 23, so that the slide bar 12 can be sucked out slowly, and as the door leaf is continuously opened, the first magnet 14 is opposite to the second magnet 23, at the moment, the suction force is increased, and the slide bar 12 is also moved out of a part, so that the slide bar 12 can be adsorbed on the base part 2 quickly. In other embodiments, more than two second magnets 23 may be provided, and the volumes of the second magnets 23 gradually increase from one side near the door leaf to the other side. When the door leaf is opened at a high speed, even if the first magnet 14 misses the time of being adsorbed with the smaller second magnet 23, the first magnet can be adsorbed with the second magnet 23 with a subsequent large volume and a large suction force, so that the door leaf can be adsorbed and fixed each time the door leaf is opened.

In this embodiment, the second magnets 23 are made of the same material, and the size of the attraction force with the first magnet 14 is adjusted by adjusting the size of the volume. In other embodiments, a plurality of second magnets 23 with different materials may be used, in which case, each second magnet 23 is disposed between the fixing base 21 and the cover 22 in such a way that the adsorption force of the second magnet when the second magnet is aligned with the first magnet 14 gradually increases from one side close to the door leaf to the other side, which can achieve the above effect.

In addition, referring to fig. 4, in this embodiment, a door is further disclosed, which includes the hidden door stopper described above for the door leaf 3, where a mounting hole is provided on a lower end surface of the door leaf 3, the top seat portion 1 is fixed in the mounting hole, and the base portion 2 is fixed on the ground 4. The door leaf 3 can rotate or slide and connect on other structures, when the door leaf 3 is opened a preset angle or a preset distance, the second magnet 23 attracts with the first magnet 14, and the lower end of the slide bar 12 passes out of the through hole 114 and is absorbed on the base part 2, so as to achieve the purpose of fixing the door leaf 3.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
