Description

Technical Field

[0001] This utility model relates to the field of door catch technology, and more specifically, to an adjustable damping door catch. Background Technology

[0002] A door catch, also known as a door stopper, is a device that holds a door in place after it has been opened, preventing it from closing due to wind or contact. It typically consists of a base mounted on the wall and a suction head mounted on the back of the door, using the magnetic force of the suction head to position the door.

[0003] To prevent the door shutter from being blown by the wind and causing the suction head on the door to hit the suction base, or to reduce the impact noise of the suction head hitting the suction base, dampers are installed on the suction base to slow down the impact speed of the suction head hitting the suction base, thus protecting the door shutter.

[0004] To achieve the door leaf positioning function, the suction block on the suction head needs to be aligned with the suction base when the door leaf is open. However, the door leaf is at a certain angle to the wall when open, and is not parallel. Therefore, the angle between the suction base and the suction head is different depending on the installation position of the door stopper. To ensure that the suction base and the suction head can fit together precisely, existing door stoppers require precise determination of the installation position during installation, which has very high requirements for installation accuracy and causes installation trouble. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable damping door catch.

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

[0007] An adjustable damping door catch includes a catch head and a catch base with a built-in magnet, the catch base being provided with a damper; the catch head includes a magnetic component, a base, and a base cover;

[0008] The base has a rotating groove at one end, and the magnetic component has a rotating adjustment part at one end that is adapted to the rotating groove. The other end passes through the compression damper from the opening of the base head cover and cooperates with the suction seat.

[0009] The base head cover is threaded into the base, so that the base head cover presses against the rotating adjustment part of the base, and fixes the rotating adjustment part in the rotating groove.

[0010] The present invention is further provided that: the rotating groove is hemispherical in shape, and the rotating adjustment part is spherical in shape.

[0011] The present invention is further provided with a groove at the end of the suction base facing the magnetic component, and the buffer rod of the damper is placed in the groove;

[0012] The end of the magnetic component is provided with a magnetic head that matches the groove. The magnetic head is drawn into the groove by a magnet and compresses the buffer rod inward.

[0013] The present invention further includes an annular silicone pad located inside the bottom wall of the groove.

[0014] The beneficial effects of this utility model are as follows: The suction head of the door catcher includes a magnetic component, a base, and a base cover.

[0015] The base has a rotating groove at one end. One end of the magnetic component has a rotating adjustment part that matches the rotating groove, and the other end passes through a compression damper through an opening in the base cover and engages with the suction base. The rotating adjustment part of the magnetic component is placed in the rotating groove, and the base cover is threaded into the base, so that the base cover presses against the base to fix the magnetic component to the base. When the suction base and suction head are installed, if the position of the magnetic component does not correspond to that of the suction base and the magnetic component needs to be adjusted, simply unscrew the base cover outward. The base cover will release the locking of the magnetic component, allowing the rotating adjustment part of the magnetic component to rotate within the rotating groove. When the magnetic head of the magnetic component is adjusted to the position opposite to the suction base, tighten the base cover inward to re-fix the magnetic component. There is no need to disassemble and reinstall the suction head, reducing the installation accuracy requirements of the door catch. Attached Figure Description

[0024] See attached document Figures 1 to 7 The present invention provides a more detailed description of an adjustable damping door catch.

[0025] An adjustable damping door catcher includes a suction head 1 and a suction base 2 with a built-in magnet 22. The suction base 2 is provided with a damper 23. The suction head 1 includes a magnetic component 11, a base 12 and a base cover 13, wherein the magnetic component 11 is made of stainless iron.

[0026] The base 12 has a rotating groove 121 at one end. The magnetic component 11 has a rotating adjustment part 111 at one end that is adapted to the rotating groove 121, and the other end passes through the opening of the base head cover 13 to compress the damper 23 (where the damper 23 is a prior art product) and cooperates with the suction seat 2. The rotating adjustment part 111 of the magnetic component 11 is placed in the rotating groove 121. The base head cover 13 is threaded to the base 12, so that the base head cover 13 presses the rotating adjustment part 111 against the base 12, fixing the rotating adjustment part 111 in the rotating groove 121. Thus, the magnetic component 11 is firmly fixed to the base 12.

[0027] After the suction base 2 and suction head 1 are installed, if the position of the magnetic component 11 does not correspond to that of the suction base 2 and the direction of the magnetic component 11 needs to be adjusted, simply unscrew the base cover outwards. The base cover will release the lock on the magnetic component 11, allowing the rotation adjustment part 111 of the magnetic component 11 to rotate within the rotation groove 121. When the magnetic head 112 of the magnetic component 11 is adjusted to a position opposite to the suction base 2, tighten the base cover 13 inwards to re-fix the magnetic component 11. There is no need to disassemble and reinstall the suction head 1, reducing the installation accuracy requirements of the door catcher.

[0028] The rotating groove 121 is hemispherical and the rotating adjustment part 111 is spherical, so that the rotating adjustment part 111 of the magnetic component 11 can rotate in any direction relative to the rotating groove 121, thereby increasing the adjustment angle of the magnetic component 11 and making the door catcher more versatile.

[0029] The suction cup 2 has a groove 21 at one end facing the magnetic component 11. The buffer rod 231 of the damper 23 is placed in the groove 21. An annular silicone pad 211 is provided in the bottom wall of the groove 21. A magnetic head 112 adapted to the groove 21 is provided at the end of the magnetic component 11. The magnetic head 112 is attracted into the groove 21 by the magnet 22 and compresses the buffer rod 231 inward. When the door is opened, the magnetic head 112 on the suction cup 1 approaches the suction cup 2. The magnet 22 in the suction cup 2 will attract the magnetic head 112 into the groove 21 of the suction cup 2. The magnetic head 112 will compress the buffer rod 231 inward and slowly abut against the annular silicone pad 211 on the bottom wall of the groove 21, reducing the impact force of the magnetic head 112 on the suction cup 2, reducing the noise generated as a result, and improving the service life of the product.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
