DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] A silent door suction device comprises a collision head mounted on a rotating door and a door stopper mounted on a wall, wherein:

[0020] The collision head structure is as follows Figure 1 , Figure 2As shown, it includes a door stopper base 1, a first pin shaft 2, a spring 16, a second pin shaft 5, a spring sheet 4 and a movable collision head 3, the door stopper base 1 is provided with a pin shaft slot 103 and a pin shaft hole 101, the first pin shaft 2 slides along the pin shaft slot 103, the second pin shaft 5 is installed in the pin shaft hole 101, the two ends of the spring 16 are respectively fixed on the first pin shaft 2 and the second pin shaft 5, the movable collision head 3 is sleeved on the outside of the door stopper base 1, the movable collision head 3 is provided with a movable collision head hole 302, the end of the first pin shaft 2 passes through the movable collision head hole 302, a spring sheet 4 is provided on the upper inner wall of the movable collision head 3, the inner side of the spring sheet 4 is pressed on the second pin shaft 5, the door stopper base 1 is provided with a lower tooth 102, the inner wall of the movable collision head 3 is also provided with an upper tooth 303, and the movable collision head 3 is provided with a front inclined surface 301 at one end close to the door stop;

[0021] The door stop structure is as follows Figure 3 , Figure 4 As shown, it includes a door stop base 7, a magnet 8 and a movable pressure rod 9. A movable pressure rod mounting seat 701 is provided on the upper part of the door stop base 7. The movable pressure rod 9 includes a pressure rod 901 and a spring 10. A limit block 902 is provided on the pressure rod 901. The pressure rod 901 passes through the spring 10 and passes downward out of the movable pressure rod mounting seat 701. The magnet 8 is fixed on the door stop base 7 and is located below the movable pressure rod mounting seat 701. The magnet 8 is fixedly mounted on the door stop base 7 by screws; the movable pressure rod 9 is movably mounted on the door stop base 7; the spring 16 is movably mounted on the movable pressure rod 9; and the end cover 11 is fixedly mounted on the door stop base 7 by 4 screws.

[0022] An end cover 11 is provided on the door stop base 7 , and the upper end of the movable pressure rod 9 passes through the end cover 11 . Both ends of the spring 10 abut against the end cover 11 and the limit block 902 of the pressure rod 901 , respectively.

[0023] The pin shaft slot 103 and the movable collision head hole 302 are both oblong holes.

[0024] The working principle of the present invention is as follows Figures 5 to 8 As shown:

[0025] 1. When the door rotates to the maximum position, the movable collision head under the door frame moves together; at this time, the movable collision head 3 is not in contact with the door stop, and the movable collision head 3 is lifted freely under the action of the spring sheet 4. Figure 5 As shown;

[0026] 2. Door movement Figure 6 When the door moves to the position, the movable pressure rod 9 on the door stop begins to contact the front inclined surface 301 of the movable collision head 3; Figure 7When the movable collision head 3 installed on the door is in the position, it is pressed down by the movable pressure rod 9 on the door stopper. At this time, the movable collision head 3 and the magnet 8 are not in contact, and the upper teeth 303 of the movable collision head 3 and the lower teeth 102 of the door stopper base 1 are not engaged.

[0027] 3. Continue to push the door all the way, and the movable collision head 3 and the magnet 8 begin to contact and attract each other. Figure 8 As shown, in this process, due to the buffering of the spring 16 and the damping effect of the upper teeth 303 and the lower teeth 102 during the meshing process, the sound when the door suction device is fixed at the maximum position is almost eliminated;

[0028] 4. When the door needs to be released, since the upper teeth 303 of the movable collision head 3 and the lower teeth 102 of the door stop base 1 are in a meshing state, and the upper surface of the movable collision head 3 is supported by the movable pressure rod 9, when the magnet 8 and the movable collision head 3 installed on the door are separated, there is no noise generated by relative movement of other parts; when the movable collision head 3 and the movable pressure rod 9 on the door stop are completely separated, the movable collision head 3 is reset under the action of the spring sheet 4 and the spring 6.

[0029] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
