door seal

Abstract

The present invention relates to a door sealing device, in particular to a door sealing device for use when installed on the front door seam of an outdoor door. A door sealing device installed in the front door gap of the door. The sealing device includes an outwardly opening sealing shell. The sealing shell includes side plates and a fixing component located on the inside. The fixing component is used to support and lift up from the sealing shell. The sunken sealing strip, the parallel part of the fixed component parallel to the side plate and the parallel part of the sealing strip are characterized in that at least one first arched body is provided in the sealing strip, and the arched body faces the direction of the surface to be sealed, and the arched body A contact surface for sealing is provided, and a sealing lip is provided on the side of the sealing strip that can face the surface to be sealed. The sealing lip is provided with a contact surface for sealing. Compared with the prior art, the door sealing device of the present invention has better sealing performance and longer service life.

Description

technical field [0001] The invention relates to a door sealing device, in particular to a door sealing device used for installation in the front door seam of an outdoor gate. Background technique [0002] In the patent document EP 11 74 579 A2, a sealing device for a structure without a sill is mentioned, wherein a sealing strip is provided, and the sealing strip has three contact surfaces, including the surface to be sealed, and all the contact surfaces have the same height, Moreover, the side wall of the sealing strip is parallel to the side plate of the sealed casing, and the side walls of the sealing strip are equipped with parallel, pre-raised hardening strips. When the sealing strip descends and gradually breaks away from the sealed casing, each The hardened band will also leave the sealed shell one after another, so there are some disadvantages, especially, for the hardened band that has not left the sealed shell, it bears an unchangeable pressure, and the sealing for...

[0002] In the patent document EP 11 74 579 A2, a sealing device for a structure without a sill is mentioned, wherein a sealing strip is provided, and the sealing strip has three contact surfaces, including the surface to be sealed, and all the contact surfaces have the same height, Moreover, the side wall of the sealing strip is parallel to the side plate of the sealed casing, and the side walls of the sealing strip are equipped with parallel, pre-raised hardening strips. When the sealing strip descends and gradually breaks away from the sealed casing, each The hardened band will also leave the sealed shell one after another, so there are some disadvantages, especially, for the hardened band that has not left the sealed shell, it bears an unchangeable pressure, and the sealing force acting on the surface to be sealed by the sealing strip is only It can withstand and cannot be changed. Also, the side panels of the sealed enclosure are easily polluted from the inside out, and the main dirt particles that cause pollution are hidden between the pre-raised sealing strips. Therefore, in the sealing device of the outdoor door , the sealing strip is more prone to cracks and can even lead to mechanical failure of the entire door seal

[0003] In addition, the current existing door sealing device cannot respond in a short time to the variable air pressure caused by the variable climate. For example, when a strong wind comes, dust will penetrate into the crack of the door or hit the door The raindrops will also seep into the cracks in the door
