Detailed Description

In the first embodiment, referring to fig. 1 to 5, the silent repulsion door stopper comprises a fixed seat fixed on a wall and a fixed head correspondingly fixed on the back of a door leaf;

Rubber circle first and rubber circle second's cross sectional shape be the triangle-shaped form, be convenient for carry out crisscross contact between rubber circle first and the rubber circle second, its cross sectional shape also can establish into other suitable shapes such as arc simultaneously.

The fixing plate and the mounting plate are respectively provided with a mounting hole A and a mounting hole B which are uniformly distributed along the circumference, the mounting hole A is used for fixing the fixing seat on the wall, and the mounting hole B is used for fixing the fixing head on the door leaf.

The free end of the guide post is provided with a stop lug, and the stop block corresponds to a positioning block arranged at the port of the guide sleeve, so that the guide post is prevented from accidentally separating from the guide sleeve to influence the use.

The outer end face of the partition board is provided with a spongy cushion which is fully distributed on the end face of the partition board and used for preventing the buffer block from impacting the partition board to generate noise.

The utility model discloses a use and principle:

the fixed head is fixed on the back of the door leaf through the mounting hole B, the fixed seat is fixed on a wall corresponding to the position of the fixed head through the mounting hole A, when the door leaf is opened, a limiting block on the fixed head gradually extends into the fixed head from the opening end of the limiting sleeve, the rubber ring A and the rubber ring B are in mutual cross contact to generate certain contact friction force, the fixed seat and the fixed head are relatively fixed, so that the door leaf is limited, meanwhile, when the limiting block extends into the limiting sleeve, a repulsive force can be generated between the limiting block and two homopolar magnets on the buffer block, the elastic force of the spring prevents the limiting block from excessively extending into the fixed head to generate impact noise, and if a large impact force is met, the buffer block is forced to move inwards to be in contact with the partition plate, the buffer is buffered through the sponge cushion, and the impact noise is avoided; the utility model provides a fixed head and fixing base are fixed through alternately forming frictional resistance between many circles of rubber circle, and the contact sound between the rubber circle is less, can not produce rich people's noise, and the buffering through repulsion force and spring force of homopolar magnet between fixed head and the fixing base makes between fixed head and the fixing base not have rigid collision simultaneously, and has certain cushioning effect when meeting great impact force, both can protect the door and can protect the door-inhale.
