[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0027] Embodiment 1:

[0028] like Figure 1-Figure 2 As shown, in one embodiment, a heat-insulating extremely narrow sliding door profile includes: a profile body 1, a support cavity 2 is symmetrically arranged inside the profile body 1, which enhances the overall rigidity and stability of the profile body 1, and a clamping groove 3 with an upward opening is opened in the middle of the support cavity 2 for clamping other door and window components. Specifically, the width of the clamping groove 3 is 10-15 mm, and the depth of the clamping groove 3 is 6-12 mm.

[0029] Furthermore, the end surfaces of both sides of the profile body 1 are provided with anti-skid grooves 5, on which components such as anti-skid strips can be installed. Specifically, the anti-skid grooves 5 are arranged in 4-8 groups at equal intervals.

[0030] like Figure 1-Figure 2 As shown, in this embodiment, the profile body 1 includes a composite material layer 11 and a coating layer 12, and the coating layer 12 is sprayed on the outside of the composite material layer 11, and the supporting strength and weather resistance of the extremely narrow sliding door profile are improved by the composite material layer 11 and the coating layer 12. Specifically, the thickness of the profile body 1 is 1.2-3.2 mm.

[0031] Furthermore, the composite material layer 11 is integrally formed, and the material of the composite material layer 11 is a glass fiber thermosetting resin composite material. The cost of the glass fiber pultruded thermosetting resin composite material is only half of that of aluminum alloy, while its strength is five times that of aluminum alloy, and its thermal conductivity is only one thousandth of that of aluminum alloy. It is an ideal material to replace aluminum alloy for use in extremely narrow sliding door profiles.

[0032] During the specific preparation, the glass fiber is drawn out through the yarn rack and passes through the yarn guide plate, and enters the material tank filled with liquid thermosetting resin. Under the full infiltration of the liquid thermosetting resin, the glass fiber is continuously pulled through the mold by the traction device; when passing through the heated mold, the liquid thermosetting resin is gradually solidified, and then the composite material is continuously pulled out of the mold to form a continuous glass fiber pultruded thermosetting resin composite material. Specifically, the thickness of the composite material layer 11 is 1-3 mm.

[0033] Furthermore, the material of the coating layer 12 is any one of epoxy powder coating, polyester powder coating and epoxy polyester powder coating, which has the characteristics of wear resistance, weather resistance and corrosion resistance, thereby enhancing the weather resistance of the profile.

[0034] During the specific preparation, the glass fiber pultruded thermosetting resin composite material is subjected to electrostatic powder spraying and high temperature curing treatment. After curing, the powder coating forms a protective layer on the glass fiber pultruded thermosetting resin composite material to ensure that the product will not be bumped or exposed during transportation or use, and the electrostatic powder that is not adsorbed to the composite material layer 11 during spraying can be recycled and reused, which can effectively reduce production costs. Specifically, the thickness of the coating layer 12 is 50-80 μm.

[0035] Embodiment 2:

[0036] like Figure 3 As shown, in this embodiment, a limiting portion 31 is symmetrically arranged on the top of the clamping groove 3 to limit the position during the installation, adjustment and maintenance of the door and window. Specifically, the width of the limiting portion 31 is one fifth of the clamping groove 3.

[0037] Embodiment three:

[0038] like Figure 4 As shown, in this embodiment, support legs 4 are symmetrically arranged at both ends of the lower part of the profile body 1 to ensure the stable installation of the profile body 1. The support legs 4 include a first support leg 41 and a second support leg 42, and the second support leg 42 is symmetrically arranged between the first support leg 41.

[0039] Furthermore, the end of the first support leg 41 is bent inward to form a hook leg portion 411, so that the support leg 4 can be better fixed on the ground or other supporting surfaces, thereby increasing its stability; a sealing groove 6 is formed between the first support leg 41 and the second support leg 42, which can prevent water or other debris from entering the interior of the support leg 4 after the sealing strip is installed, thereby extending its service life and reducing maintenance costs.

[0040] Furthermore, the second legs 42 are bent inward to form a step portion 421, which increases the stability of the installation; a mounting groove 7 is formed between the second legs 42, which can be used to install other accessories or connectors to achieve assembly and fixation of the profile body 1 with other components.

[0041] Through the above technical solution, the profile body 1 of the ultra-narrow sliding door profile of the present application includes a composite material layer 11 and an externally sprayed paint layer 12. A layer of cured paint is formed by electrostatic powder spraying and high-temperature curing of the glass fiber pultruded thermosetting resin composite material. This layer of paint gives the profile a metallic texture, improving its appearance and texture; at the same time, it improves the structural strength and weather resistance of the profile, protects the surface integrity of the profile, enables it to be used stably for a long time under various environmental conditions, effectively prevents possible bumps during transportation and use, thereby avoiding the occurrence of bottom exposure, and also reduces the actual production cost.

[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
