Description

Technical Field

[0001] The utility model relates to the technical field of sealing rubber strips, in particular to a bent type sealing rubber strip structure. Background Art

[0002] Sealing strip is a strip or rod-shaped material used for product sealing, usually made of rubber and elastic. It is mainly used in building doors and windows, automobiles, machinery and other fields to ensure the sealing, sound insulation, heat insulation and shock absorption of the product. The quality of the sealing strip directly affects the performance and service life of the product. In the field of building doors and windows, the performance of the sealing strip directly affects the sealing, sound insulation, heat insulation and shock absorption of doors and windows. It has good sealing, sound insulation, heat insulation and shock absorption effects, which plays an important role in improving the performance and service life of the product.

[0003] Common bending type sealing strip structures are usually made of rubber. When installing, first remove the debris in the notch of the door and window, tear off the tape on the sealing strip, align it with the notch of the door and window or the part that needs to be sealed, and press the sealing strip tightly with your hands or special tools to ensure that it fits tightly with the notch of the door and window. Traditional sealing strips are usually integrated structures. They are installed in the notch of the door and window during installation. They will bend at the corners of the door and window, and are prone to displacement or falling off during long-term use. The existing solution is to add a buckle at the bend of the sealing strip to ensure the stability of the sealing strip. However, the method of adding a buckle will not only increase the overall use cost and increase the difficulty of installation at the door and window during use, but also affect the overall aesthetics, limit the scope of application, and cause difficulties in maintenance and replacement. For this reason, a bending type sealing strip structure is proposed. Utility Model Content
