Technical Field

[0001] The utility model belongs to the technical field of sealing, in particular to a door leaf heat-insulating nylon strip. Background Art

[0002] In modern buildings, the thermal insulation performance of doors and windows is crucial for energy saving and comfort. Traditional thermal insulation materials for doors and windows are mostly made of metal, plastic and other materials, but these materials have certain limitations in thermal insulation performance, mechanical strength and durability. In order to improve the thermal insulation performance of doors and windows, various new thermal insulation materials and structural designs have appeared on the market.

[0003] At present, as a new type of thermal insulation material, door leaf thermal insulation nylon strips are widely used in door and window structures. The thermal insulation material is mainly used to divide the thermally insulated door leaf into an inner part and an outer part, and the inner part and the outer part are separated by the door leaf thermal insulation nylon strips to achieve the effect of no contact between the two and reduce heat transfer. However, the thermal insulation nylon strips for thermally insulated door leaves in the prior art are simple sheets, which are directly placed between the outer part and the inner part. The thermal insulation effect is average and the installation is relatively troublesome. Summary of the invention

[0004] The utility model aims to solve the above problems in the prior art and proposes a door leaf heat-insulating nylon strip, which has the characteristics of good heat-insulating effect.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A door leaf insulation nylon strip comprises: a main body, wherein the main body comprises a first insulation part and a second insulation part, wherein the first insulation part comprises a channel arranged along the length direction; the first insulation part comprises a first support surface and a second support surface, and the first support surface and the second support surface are located on both sides of the channel, the second insulation part is connected to the first insulation part, a clamping groove is formed between the second insulation part and the first support surface, the second insulation part comprises a protrusion arranged along the length direction, and the protrusion is located in the clamping groove; the protrusion is extended from the second insulation part toward the first support surface, and gradually decreases in width, and the end of the protrusion is gathered to form a line.

[0007] In the above-mentioned door leaf insulation nylon strip, the main body also has a third insulation part, which is connected to the first insulation part and is located on the side of the second supporting surface of the first insulation part.

[0008] In the above-mentioned door leaf insulation nylon strip, the free end of the second insulation part has a guide surface, which is one of the side surfaces of the protrusion. The guide surface and the first supporting surface form a trumpet-shaped inlet, which is connected to the engaging groove.

[0009] In the above-mentioned door leaf insulation nylon strip, the first insulation part has a third support surface, and the third support surface is located between the first support surface and the second support surface and is adjacent to the third insulation part.

[0010] Compared with the prior art, this application has the following advantages:

[0011] In the present application, a channel is provided in the first heat insulating part to form an air layer, effectively reducing heat transfer and improving the overall heat insulating effect. The first support surface and the second support surface of the first heat insulating part provide a stable support structure to ensure the stability of the door leaf heat insulating nylon strip during use. The engaging groove formed between the second heat insulating part and the first heat insulating part makes the installation process easier and ensures that the door leaf heat insulating nylon strip is pre-set on the outer part of the door leaf. It is easier to connect the inner part by bolts afterwards, and there is no need to manually maintain the position of the door leaf heat insulating nylon strip. The convex design on the second heat insulating part can better abut against the door leaf to form a line sealing effect. Made of nylon material, it has good mechanical strength and durability, and can effectively play a heat insulating role for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiment is only one embodiment of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Figure 1 Shown is a schematic cross-sectional view of any one of the locations of the door leaf insulation nylon strip.

[0019] like Figure 1 to Figure 2 As shown, a door leaf insulation nylon strip includes: a main body 2, the main body 2 has a first insulation part 21 and a second insulation part 22, the first insulation part 21 has a channel 211 arranged along the length direction; the first insulation part 21 has a first support surface 212 and a second support surface 213, and the first support surface 212 and the second support surface 213 are located on both sides of the channel 211, the second insulation part 22 is connected to the first insulation part 21, and a clamping groove 221 is formed between the second insulation part 22 and the first support surface 212, the second insulation part 22 has a protrusion 222 arranged along the length direction, and the protrusion 222 is located in the clamping groove 221; the protrusion 222 is from the second insulation part 22 to the first support surface 212, and gradually decreases in width, and the end of the protrusion 222 is gathered to form a line.

[0020] In the present application, by setting a channel 211 in the first heat insulating part 21, an air layer is formed, which effectively reduces heat transfer and improves the overall heat insulation effect. The first support surface 212 and the second support surface 213 of the first heat insulating part 21 provide a stable support structure to ensure the stability of the door leaf heat insulation nylon strip during use. The clamping groove 221 formed between the second heat insulating part 22 and the first heat insulating part 21 makes the installation process easier and ensures that the door leaf heat insulation nylon strip is pre-clamped on the outer part 102 of the door leaf 100. It is easier to connect the inner part 101 by bolts, and there is no need to manually maintain the position of the door leaf heat insulation nylon strip. The protrusion 222 on the second heat insulating part 22 can better abut against the door leaf 100 to form a line sealing effect. Made of nylon material, it has good mechanical strength and durability, and can effectively play a heat insulation role for a long time.

[0021] In the present application, the inner portion 101 of the door leaf 100 refers to the door leaf 100 facing the indoor side, and the outer portion 102 refers to the door leaf 100 facing the outdoor side.

[0022] Specifically, the main body 2 further has a third heat insulating portion 23 , which is connected to the first heat insulating portion 21 and is located on one side of the second supporting surface 213 of the first heat insulating portion 21 .

[0023] During the actual installation process, the third heat insulating part 23 is arranged between the inner part 101 and the outer part 102 of the door leaf 100 to form a partition, which effectively avoids slight deformation that may occur during the installation process and prevents the inner part 101 and the outer part 102 of the door leaf 100 from contacting each other.

[0024] Specifically, the free end of the second heat insulating portion 22 has a guide surface 2221 , which is one of the side surfaces of the protrusion 222 . The guide surface 2221 and the first supporting surface 212 form a trumpet-shaped inlet 2211 , and the inlet 2211 is connected to the engaging groove 221 .

[0025] The free end of the second insulation part 22 has a guide surface 2221, which is one of the side surfaces of the protrusion 222, forming a trumpet-shaped inlet 2211, making installation more convenient and quick. The trumpet-shaped inlet 2211 is connected to the locking groove 221, providing a better guiding effect, ensuring that the outer part 102 of the door leaf 100 can be clamped smoothly.

[0026] Specifically, the first heat insulating portion 21 has a third supporting surface 214 , and the third supporting surface 214 is located between the first supporting surface 212 and the second supporting surface 213 , and is adjacent to the third heat insulating portion 23 .

[0027] The third support surface 214 is also in close contact with the outer portion 102 of the door leaf 100, and the third heat insulating portion 23 is also in close contact with the outer portion 102. Therefore, even if the door leaf 100 is deformed later, the inner door leaf 100 is in close contact with the third heat insulating portion 23, and the third heat insulating portion 23 will not be damaged, thereby avoiding contact with the outer portion 102 of the door leaf 100.
