A door bottom sealing device

Abstract

The invention provides a door bottom sealing device comprising a mounting plate, a pressing plate and a driving component. One end of the pressing plate is hinged to the mounting plate while a sealing strip is detachably mounted at the other end; an elastic piece used for keeping the pressing plate horizontal under the normal state is arranged between the mounting plate and the pressing plate; the pressing plate corresponds to the driving component; the driving component is mounted at the bottom of a door frame on one side of a door lock; the driving component comprises an axle and an eccentric wheel fixedly mounted on the axle. The sealing device is simple in structure and easy to produce, and installation can be realized without slotting at the original door bottom and destroying the door body structure. According to accurate requirements, pressure of the sealing strip upon the ground can be adjusted conveniently. The sealing strip is a rubber sealing strip which is anti-aging, long in service life and low in cost. The eccentric wheel is a nylon wheel which is tough, wear resistant and long in service life and has silencing effect. A wear-resistant layer is arranged on the eccentric wheel, so that service life of the eccentric wheel is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of door bottom sealing equipment, in particular to a door bottom sealing device. Background technique [0002] The door bottom sealer is usually installed in the groove opened at the bottom of the door, and is used to seal the gap between the door and the ground to block external dust, peculiar smell, mosquitoes, noise, etc. In the existing technology, the door bottom sealer mainly It includes a drive rod, multiple upper sliders, and multiple lower guide blocks. The upper slider and the lower guide block are connected by a curved spring, and the lower guide block is connected with the sealing pressure plate; when working, the drive rod pushes the upper slider, and the upper slider passes through the curved spring The spring drives the lower guide block. The curved spring converts the horizontal displacement of the upper slider into the vertical displacement of the lower guide block. The lower guide block dri...

[0002] The door bottom sealer is usually installed in the groove opened at the bottom of the door, and is used to seal the gap between the door and the ground to block external dust, peculiar smell, mosquitoes, noise, etc. In the existing technology, the door bottom sealer mainly It includes a drive rod, multiple upper sliders, and multiple lower guide blocks. The upper slider and the lower guide block are connected by a curved spring, and the lower guide block is connected with the sealing pressure plate; when working, the drive rod pushes the upper slider, and the upper slider passes through the curved spring The spring drives the lower guide block. The curved spring converts the horizontal displacement of the upper slider into the vertical displacement of the lower guide block. The lower guide block drives the sealing pressure plate to move downward to achieve the sealing effect. The structure is complex, the production cost is high, and it is installed and disassembled at the same time. It is time-consuming and labor-intensive, and it is necessary to slot the bottom of the original door, which destroys the structure of the door body and often affects the service life of the door
