Abstract

The utility model relates to an automatic door sealer, comprising a screw cap (1), a rolling ring (2), a check ring (3), a shaft (4), a fixing sheet (5), a fixing hole (6), springs (7), a plate body (8) and an elastic bar (9), wherein, the fixing sheet is hinged with the plate body, and the springs is arranged between the fixing sheet and the plate body. The utility model can make the bottom of the door not provided with a gap and has the advantages of sound isolation, simple installation, practicality and beauty, and the invasion of cold wind, dust, mosquito, rain water, etc. can be avoided.

Description

Automatic door sealer

The utility model is about a kind of device of sealing up a door, more particularly about a kind of energy dust-break soil, the self-sealing device of sealing up a door.

All be provided with door between general office space or housing types, and belong to employed doors such as the hall, bedroom or general family kitchen no matter be, all can find as long as pay attention to a little to observe, though door is being closed, the slot that exists size, height not to wait really between the root edge of door and the ground is because apertured existence, so dust is easy to enter the room, winter, the north was cold, and sharp north wind is easy to be blown into the room from the slit, influences people's normal life.Simultaneously because the existence in slit, foreign peoples such as mosquito rope, insect, reptile, mouse are easy to invade and breeding, or cause when rainy rainwater to be invaded by the slit and drench at the ground and the door end, not only can influence sanitation of environment, and quicken corrosion or damage at the bottom of making.

Automatically the device of sealing up a door at the bottom of main purpose of the present utility model is to provide a kind of, when door is closed, can be automatically with the gap closing at the bottom of the door and between ground.

The device of sealing up a door automatically that the utility model proposes comprises nut, rolling ring, back-up ring, axle, stator, fixing hole, spring, plate body, elastic strip and connecting rod.Have fixing hole on the stator, stator is connected with plate body by the hinge mode, settles spring between stator and plate body, and the elastic force of dependence spring is controlled the lifting of plate body.

Do not produce the slit at the bottom of the device of sealing up a door of the present utility model can make, can stop the intrusion of cold wind, dust, mosquito, rainwater etc. like this, and have deadening, and its color can make different colours according to needs are installed, install simple, both artistic and practical.

Below further specify and set forth the present invention by accompanying drawing.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is a scheme of installation of the present utility model.

In Fig. 1 and Fig. 2, symbol (1) is represented nut, and symbol (2) is represented rolling ring, symbol (3) is represented back-up ring, symbol (4) is represented axle, and symbol (5) is represented stator, and symbol (6) is represented fixing hole, symbol (7) is represented spring, symbol (8) is represented plate body, and symbol (9) is represented elastic strip, and symbol (10) is represented connecting rod, symbol (11) is represented Men Ti, and symbol (12) is represented doorframe.

In the utility model, axle (4) is connected by connecting rod (10) with plate body (8), be equipped with nut (1), rolling ring (2), back-up ring (3) on the axle (4), have fixing hole (6) on the stator (5), stator (5) and plate body (8) are hinged, spring (7) is installed between stator (5) and the plate body (8), and plate body (8) is connected as nail, riveting, weldering or chemical adhesion mode mechanically with elastic strip (9).The quantity of stator can be 1 to 5, even more, but preferably 3.Spring between stator and plate body plays the lifting of control panel body.

In the utility model, nut (1) can replace with other form, as riveted joint etc., rolling ring (2) can be rolling bearing or garden ring, and back-up ring can be a packing ring, itself and axle (4) welding, the shape of fixing hole (6) can be arbitrarily, as garden shape, rectangle.Be connected with a door body by fixing hole (6) device of will sealing up a door with screw or iron nail.Plate body (8) is decided according to the needs of door with the length of elastic strip (9).Elastic strip can be that rubber, plastics or non-woven material are made.

The utility model device of sealing up a door is worked as follows.

After will sealing up a door device a body being connected with door, because the adjacent doorframe of rolling ring, when door was opened, rolling ring left doorframe, and owing to the elastic force of spring, so plate body drive elastic strip is upspring built on stilts; When door was closed, rolling ring was close to doorframe, drove the plate body landing, and close proximity to ground reaches the purpose in slit at the bottom of the closing door.The utility model positive and negative installation of device by spring of sealing up a door automatically, a left side that adapts to a body is opened or open on the right side.

Spring can be positioned in the stator, also can be positioned on arbitrary position of the upper limb of plate body, and the number of spring is decided on a plug size.Automatically the device of sealing up a door of the present utility model can be made of iron and steel, also can be with plastics or other material.

Claims

1, a kind of device of sealing up a door automatically, it is characterized in that comprising nut (1), rolling ring (2), back-up ring (3), axle (4), stator (5), fixing hole (6), spring (7), plate body (8), elastic strip (9), at this, axle (4) is connected by connecting rod (10) with plate body (8), axle (4) is gone up nut (1) is installed, rolling ring (2), back-up ring (3), have fixing hole (6) on the stator (5), stator (5) and plate body (8) are hinged, spring (7) is installed between stator (5) and the plate body (8), plate body (8) and elastic strip (9) mechanically or the chemical bonding mode be connected.

2, the device of sealing up a door automatically as claimed in claim 1, the quantity that it is characterized in that stator (5) can be 3.
