Description

Buffering type mute floor-mounted door stopper

Technical Field

The invention belongs to the technical field of door stoppers, and particularly relates to a buffer type mute floor-mounted door stopper.

Background

The door stopper, also called door stopper, is a device for sucking and positioning the opened door leaf to prevent the door leaf from being closed by wind blowing or touching.

The conventional door stopper mostly utilizes the suction force between the magnet and the iron sheet to fix the door panel, but the suction force between the iron sheet and the black magnet is too large, so that strong impact sound is caused, a large amount of noise is generated, and the service life of the door stopper is also shortened.

Disclosure of Invention

In order to make up for the defects of the prior art and solve the problems that the door panel is fixed by utilizing the attraction between the magnet and the iron sheet in the prior art, but the attraction between the iron sheet and the black magnet is too large, so that strong impact sound is caused, a large amount of noise is generated, and the service life of the door stopper is also shortened, the invention provides the buffer type mute floor-mounted door stopper.

The technical scheme adopted by the invention for solving the technical problems is as follows: the invention relates to a buffer type mute floor-mounted door stopper which comprises a strong magnetic block, a first plate, a second plate, a rectangular plate and a first buffer pad; the strong magnetic block is fixedly connected to the side wall of the door panel; the first plate is bolted to the top of the floor; the second plate is fixedly connected to the top of the first plate, the second plate is obliquely arranged, and the inclination angle is 15-30 degrees; the rectangular plate is fixedly connected to the top of the second plate; the first cushion pad is connected to the top of the second plate in a sliding manner; when the door plate is used, when the door plate moves towards the second plate, attractive force is generated between the strong magnetic block and the rectangular plate under the action of magnetic force, the strong magnetic block drives the first buffer pad to move towards the rectangular plate, the strong magnetic block is prevented from being in direct contact with the rectangular plate, and then large collision sound is avoided, and the door plate stops at the position through the attractive force between the strong magnetic block and the rectangular plate; the first cushion pad can be made of various soft materials, such as: rubber, silica gel, sponge, cotton cloth, etc.

Further, a first air bag is fixedly connected to one side, close to the first cushion pad, of the rectangular plate; a piston cylinder is arranged inside the rectangular plate; the first air bag is communicated with the piston cylinder; a piston rod of the piston cylinder is fixedly connected with a magnet, and the magnetism of the magnet is opposite to that of the strong magnetic block; the magnet is connected in the first groove in a sliding manner; the side wall of the magnet is fixedly connected with an annular rubber block; during the use, when the blotter slides towards the direction of rectangular plate, will make an gasbag receive the extrusion, make the inside gas of gasbag get into the rodless chamber of piston cylinder, and then the piston rod through the piston cylinder drives magnet forward motion, make strong magnet and magnet take place the inter attraction effect, the interact between strong magnet and the rectangular plate has been increased, make strong magnet adsorb near the rectangular plate tightly, the door plant also stops steadily at the assigned position, wherein, the block rubber has the cushioning effect, can avoid magnet and strong magnet direct contact, and then avoid producing the noise.
