Description

Technical Field

[0001] This utility model relates to the technical field of composite material door and window glass frame structure, specifically to a composite material profile assembly structure for a sliding door and window glass frame. Background Technology

[0002] Modern residential buildings require larger sliding doors and windows, and to ensure greater comfort, the performance requirements for these doors and windows are higher. Therefore, a type of sliding door and window made of fiberglass-reinforced composite profiles has emerged, offering significant improvements in thermal insulation and wind pressure resistance compared to traditional aluminum alloy doors and windows.

[0003] Please see Figure 1 Existing sliding window and door frames using fiberglass reinforced composite materials are typically assembled from an inner frame profile 1, an outer frame profile 2, and a snap-fit ​​profile 3. Specifically, the inner frame profile 1 and the outer frame profile 2 are first connected using an I-beam snap-fit ​​strip b, and then further secured together with screws c. This design has the following defects and shortcomings:

[0004] 1. When the size of the sliding door and window glass frame is large, the pull-out resistance of screw C is very limited. After long-term use, screw C is very likely to fall off, which will reduce the structural strength of the sliding door and window glass frame.

[0005] 2. The splicing position of the inner frame profile 1 and the outer frame profile 2 forms a cavity structure d, which not only increases the overall thickness of the sliding door and window glass frame, resulting in a smaller glass size, thus affecting the lighting capacity and aesthetics of the sliding door and window, but also, since the I-shaped splice b is basically made of corrosion-resistant metal materials such as aluminum alloy, there is a serious heat exchange problem at the position of the cavity structure d, which is not conducive to the thermal insulation performance of the sliding door and window.

[0006] Solving these problems is now a top priority. Utility Model Content

[0007] In view of this, the present invention provides a composite material profile assembly structure for sliding door and window glass frames.

[0008] The technical solution is as follows:

[0009] The first aspect of this application relates to a composite material profile assembly structure for a sliding window glass frame, comprising an inner frame profile, an outer frame profile, and a snap-on strip profile. The inner frame profile, on its side away from the outer frame profile, has a glass mounting groove and a snap-on strip mounting groove extending along its length, arranged side-by-side. The snap-on strip profile is snap-fitted into the snap-on strip mounting groove. The bottom of the snap-on strip mounting groove has a plurality of mounting holes distributed along its length. The surface of the inner frame profile closest to the outer frame profile is an inner frame splicing mating surface, and this inner frame splicing mating surface has mounting holes respectively corresponding to the mounting holes. The inner frame has a riveting connection hole facing each other. The outer frame profile has a splicing mating surface on the side of the inner frame profile that is adapted to the splicing mating surface of the inner frame. The splicing mating surface of the outer frame has riveting connection holes that are respectively aligned with the riveting connection holes of the inner frame. Each riveting connection hole of the inner frame and the corresponding riveting connection hole of the outer frame are fitted with a riveting nut. Each riveting nut is threaded with a bolt that is screwed on it, thereby locking the inner frame profile and the outer frame profile into one piece and making the adjacent surfaces of the splicing mating surface of the inner frame and the splicing mating surface of the outer frame fit together.

[0010] The above-mentioned composite material profile assembly structure for sliding window and door glass frames uses rivet nuts and bolts for locking the inner and outer frame profiles. This not only ensures a reliable ground fit between the inner and outer frame splicing surfaces, blocking air convection and heat exchange, significantly improving airtightness and thermal insulation, but also reduces the overall visible width of the sliding window and door glass frame, thereby increasing the glass size and enhancing the lighting effect and aesthetics of the sliding windows and doors. Furthermore, it offers excellent assembly convenience, and the bolts and rivet nuts are not prone to loosening even after long-term use, ensuring the long-term stability and reliability of the structural strength of the sliding window and door glass frame.

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0021] like Figures 2-7 As shown, a composite material profile assembly structure for a sliding door / window glass frame mainly includes an inner frame profile 1, an outer frame profile 2, and a snap-on strip profile 3. That is, the composite material profile assembly structure is assembled from the inner frame profile 1, the outer frame profile 2, and the snap-on strip profile 3. The rectangular frame formed by the composite material profile assembly structure can serve as a sliding door / window glass frame. Please refer to [link / reference]. Figure 2 This is a schematic diagram of a composite material profile assembly structure used as the bottom crossbeam of a sliding door / window glass frame; please refer to [link / reference]. Figure 3 This is a schematic diagram of a composite material profile assembly structure used as the top crossbeam of a sliding door / window glass frame; please refer to [link / reference]. Figure 4 This is a structural diagram showing the composite material profile assembly structure used as the left-side support column of a sliding door / window glass frame; please refer to [link / reference]. Figure 5 This is a structural diagram of a composite material profile assembly structure used as the right-side column of a sliding door / window glass frame.

[0022] Please see Figure 9 When composite material profile assembly structures are used as the top crossbeam of sliding door and window glass frames, they can cooperate with door and window tracks after installing pulleys and other matching components.

[0023] Please see Figure 2 and Figure 6 On the side of the inner frame profile 1 away from the outer frame profile 2, there are glass mounting grooves 11 and fastener mounting grooves 12 extending along its length. That is, on the side of the inner frame profile 1 near the glass A, there are glass mounting grooves 11 and fastener mounting grooves 12. The fastener profile 3 is installed in the fastener mounting groove 12 by snap-fit.

[0024] When installing glass A, first remove the retaining strip profile 3 from the retaining strip mounting groove 12, then place glass A in the glass mounting groove 11, and then insert the retaining strip profile 3 into the retaining strip mounting groove 12 to achieve the positioning of glass A. Finally, the gap between the retaining strip profile 3 and glass A, as well as the gap between glass A and the groove wall of the glass mounting groove 11 on the side away from the retaining strip mounting groove 12, are filled with weather-resistant sealant e, thereby achieving reliable installation of glass A.

[0025] In this embodiment, the bottom of the fastener mounting groove 12 is provided with a plurality of mounting holes 13 distributed along its length. The surface of the inner frame profile 1 near the outer frame profile 2 is the inner frame splicing mating surface 141, on which are provided inner frame riveting connection holes 15 corresponding to each mounting hole 13. That is, the number of mounting holes 13 and inner frame riveting connection holes 15 is the same. The surface of the outer frame profile 2 near the inner frame profile 1 is the outer frame splicing mating surface 211 adapted to the inner frame splicing mating surface 141. The outer frame splicing mating surface 211 is provided with outer frame riveting connection holes 22 corresponding to each inner frame riveting connection hole 15. That is, the number of outer frame riveting connection holes 22 and inner frame riveting connection holes 15 is the same. Each inner frame riveting connection hole 15 is fitted with a rivet nut 4 on its corresponding outer frame riveting connection hole 22. Each rivet nut 4 is threaded with a bolt 5 tightened thereon, thereby locking the inner frame profile 1 and the outer frame profile 2 into one piece, and making the adjacent surfaces of the inner frame splicing mating surface 141 and the outer frame splicing mating surface 211 fit together.

[0026] Specifically, the rivet nut 4 is first fixed to the inner frame rivet connection hole 15 and the corresponding outer frame rivet connection hole 22 using a rivet gun, and then the bolt 5 is screwed in for further tightening and reinforcement. Therefore, the method of using the rivet nut 4 in conjunction with the bolt 5 for tightening ensures both the convenience and reliability of the assembly, making it durable.

[0027] Therefore, the inner frame profile 1 and the outer frame profile 2 are locked together by rivet nuts 4 and bolts 5. This not only ensures that the inner frame splicing surface 141 and the outer frame splicing surface 211 are reliably ground-fitted, but also blocks air convection and heat exchange, greatly improving airtightness and thermal insulation. It also reduces the overall visible width of the sliding door and window glass frame, thereby increasing the size of the glass and improving the lighting effect and aesthetics of the sliding door and window. Moreover, it is extremely convenient to assemble. In addition, after long-term use, the bolts 5 and rivet nuts 4 are not easy to loosen, ensuring the long-term stability and reliability of the structural strength of the sliding door and window glass frame.

[0028] Please see Figures 2-7The inner frame profile 1 has a hollow assembly protrusion 14 formed on the side near the outer frame profile 2. The surface of the assembly protrusion 14 near the outer frame profile 2 is the inner frame splicing mating surface 141. The side near the inner frame profile 1 has a splicing mounting groove 21 that matches the assembly protrusion 14. The bottom of the splicing mounting groove 21 is the outer frame splicing mating surface 211. The assembly protrusion 14 is embedded in the splicing mounting groove 21. By cooperating with the splicing mounting groove 21, the convenience and accuracy of installing and positioning the inner frame profile 1 and the outer frame profile 2 are improved.

[0029] Furthermore, in order to improve the structural strength of the assembled protrusion 14, several reinforcing ribs are provided in the assembled protrusion 14, thereby making the assembled protrusion 14 more impact-resistant and less prone to deformation.

[0030] Please see Figures 6-8 The two side walls of the splicing mounting groove 21 extend inward at the groove opening to form a rotating mating rib 212 and a supporting mating rib 213, respectively. On the outer wall of the splicing protrusion 14 near the rotating mating rib 212, a rotating mounting small rib 142 and a rotating mounting large rib 143 protrude. The rotating mounting large rib 143 is located on the side of the rotating mounting small rib 142 away from the bottom of the splicing mounting groove 21. The rotating mounting large rib 143 and the rotating mounting small rib 142 form a mating rib 212. The two-phase matching mounting groove 144 has a rotating mating rib 212 embedded in it. The rotating mounting small rib 142 and the rotating mounting large rib 143 are respectively supported on the two side walls of the rotating mating rib 212. Therefore, the inner frame profile 1 is first tilted so that the rotating mating rib 212 is embedded in the mounting groove 144, and then rotated so that the inner frame splicing mating surface 141 and the outer frame splicing mating surface 211 are in contact. Finally, the rivet nut 4 and bolt 5 are used to lock it, which ensures the convenience of installation.

[0031] Please see Figure 2 and Figure 8 A first sealing strip 6, with an interference fit, is installed on the side of the rotating mounting rib 142 away from the rotating mounting rib 143, between the assembly protrusion 14 and the splicing mounting groove 21. A second sealing strip 7, with an interference fit, is also installed between the assembly protrusion 14 and the supporting rib 213. Therefore, the gap between the inner frame splicing mating surface 141 and the outer frame splicing mating surface 211 is sealed from both sides by the first sealing strip 6 and the second sealing strip 7, isolating air as much as possible, preventing air convection, and further improving airtightness and thermal insulation.

[0032] Furthermore, the adjacent surfaces of the inner frame splicing mating surface 141 and the outer frame splicing mating surface 211 are filled with sealing structural adhesive 8, which not only completely isolates the air and prevents air convection, further improving air tightness and heat insulation, but also provides a wider contact surface between the inner frame profile 1 and the outer frame profile 2, making the connection strength more stable.

[0033] In this embodiment, a first sealing strip mounting groove 18 is formed in the side of the rotating mounting rib 142 away from the rotating mounting rib 143. The first sealing strip 6 is installed in the first sealing strip mounting groove 18, and the portion of the first sealing strip 6 protruding from the first sealing strip mounting groove 18 is interference-fitted between the supporting rib 213 and the assembly protrusion 14. With this design, the first sealing strip 6 is easy to install, stable and reliable, and can play a good sealing role.

[0034] Similarly, the inner frame profile 1 has an integrally formed mounting support rib 16 facing the supporting rib 213. The end of the mounting support rib 16 away from the fastener mounting groove 12 is supported on the side wall of the supporting rib 213 away from the bottom of the splicing mounting groove 21, ensuring the reliability of the positioning of the inner frame profile 1. Simultaneously, a second sealing strip mounting groove 17 is formed between the mounting support rib 16 and the splicing protrusion 14. A second sealing strip 7 is installed in the second sealing strip mounting groove 17, with the portion of the second sealing strip 7 protruding from the second sealing strip mounting groove 17 and interference-fitted between the supporting rib 213 and the splicing protrusion 14. Through this design, the second sealing strip 7 is easy to install, stable and reliable, and can provide a good sealing effect.

[0035] Please see Figure 1 In the existing technology, when the composite material profile assembly structure is used as the bottom crossbeam of the sliding door and window glass frame, the weather-resistant sealant e may crack and shrink over time due to aging, which may allow rainwater to penetrate into the inner frame profile 1. Even if there are drainage holes on the inner frame profile 1, rainwater may still not be able to drain quickly and may leak from the screw positions, thus causing the door and window to leak.

[0036] In this embodiment, please refer to Figure 2 The bottom of the glass mounting groove 11 is a sloping structure, and the distance between the bottom of the glass mounting groove 11 and the inner frame splicing mating surface 141 gradually decreases from the inner side wall of the glass mounting groove 11 to the outer side wall. Furthermore, when the composite material profile assembly structure serves as the bottom crossbeam of the sliding window glass frame, several drainage holes 19 are provided on the outer side wall of the glass mounting groove 11 at the bottom of glass A to drain water from the glass mounting groove 11. Therefore, in this embodiment, when the weather-resistant sealant e cracks and shrinks over time, causing rainwater to penetrate the inner frame profile 1, the drainage slope of the drainage holes 19 at the bottom of the glass mounting groove 11 allows rainwater to flow quickly to and be discharged through the drainage holes 19, preventing water accumulation in the glass mounting groove 11 and avoiding window / door leakage.

[0037] Furthermore, each drainage hole 19 is fitted with a hole cover 9, and each hole cover 9 has a drainage channel 91. The inner end of each drainage channel 91 is connected to the glass mounting groove 11, and the outer end of each drainage channel 91 is downward connected to the outside. With this design, since the opening of the drainage channel 91 that connects to the outside is downward, the windward side is blocked, so wind pressure is not easy to enter the drainage channel 91, thereby improving the overall airtightness and thermal insulation performance.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
