Description

Technical field

[0001] The utility model relates to the technical field of awnings, in particular to a flexible connection structure of an awning. [Background Technology]

[0002] The flexible connection structures of boarding bridge canopies, train canopies, automobile canopies, etc. are common flexible connection structures in daily life. Currently, the flexible connection structures of canopies used in the market mostly use PVC cloth or silicone cloth or a combination of the two.

[0003] PVC fabric is typically made of three layers. The middle layer is a base fabric, primarily made of polyester. Acrylic adhesive is applied to both sides of the base fabric. Silicone fabric consists of a base fabric and silicone coated on both sides. The base fabric is primarily made of asbestos.

[0004] PVC cloth tends to become brittle at low temperatures, and its bending resistance is greatly reduced. Silicone cloth itself is brittle because its base cloth is asbestos fiber, and its bending resistance is very poor. However, silicone cloth is non-combustible. PVC cloth has certain flame retardant properties, but its fire resistance level is worse than that of silicone cloth.

[0005] Because the flexible connection structure of the boarding bridge canopy and vehicle canopy is a soft connection, it is in dynamic bending motion for a long time during operation. Therefore, in various environments, especially low-temperature environments, excessive bending can easily cause holes to appear at the bending points of the soft connection, causing product failure or requiring frequent maintenance.

[0006] To solve the above problems, we provide a solution. [Utility Model Content]

[0009] According to an embodiment of the present invention, a flexible connection structure of a awning further includes a buffer block and a nylon block. The front and rear ends of the awning cloth are fixedly connected to the buffer block and the nylon block respectively.

[0010] According to a flexible connection structure of an awning in an embodiment of the present invention, the awning cloth is fixedly connected to the buffer block and the nylon block by sewing Velcro.

[0011] According to a flexible connection structure of an awning in an embodiment of the present invention, a pressing strip is provided on the buffer block along the length direction of the buffer block, and the awning cloth is located between the pressing strip and the sewn Velcro.
