Description

A type of molding used on the inside of door and window glass Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically to a pressure line used on the inside of door and window glass. Background Technology

[0002] In the modern construction industry, doors and windows serve as vital channels for communication between buildings and the external environment. Their safety and stability directly impact the building's functionality and the safety of residents' lives and property. The glazing bead, a key component for fixing the glass in doors and windows, plays a decisive role in their performance. Existing glazing bead designs, as shown in Figure 1, typically employ a structure where the left frame is connected to the right frame via a connecting strip. The bottom of the right frame has symmetrically distributed clips, and the two sets of clips are connected by a snap-fit ​​V-plate. The initial design intention of this structure was to provide doors and windows with a certain degree of wind resistance.

[0003] However, in practical applications, the stability issues of the snap-fit ​​V-plate have become increasingly apparent. The snap-fit ​​connection method is essentially a relatively simple mechanical connection. During long-term use, external environmental factors such as temperature changes, humidity fluctuations, and frequent wind pressure impacts can easily cause the snap-fit ​​V-plate and the locking pin to loosen or shift. Especially during extreme weather conditions such as typhoons and severe convective weather, significant wind pressure acts on the window and door glass, and is transmitted through the glass to the pressure rail. Because the snap-fit ​​V-plate cannot provide sufficient support and stability, the pressure rail structure can deform or even detach, resulting in the window and door glass losing its effective fixation and posing serious safety hazards such as glass breakage and injury from falling glass.

[0004] Furthermore, with increasingly higher demands for building energy efficiency and sound insulation, higher standards are being set for the sealing performance and overall strength of doors and windows. Existing window cladding structures, due to insufficient wind pressure resistance, are prone to developing gaps under wind pressure. This not only damages the sealing structure of doors and windows, allowing indoor heat to escape through the gaps and external noise to enter, affecting indoor comfort, but also accelerates the aging of door and window components, shortens their lifespan, and increases later maintenance costs. In actual building use, poor cladding sealing frequently leads to indoor temperatures that are cold in winter and hot in summer, as well as severe noise pollution, resulting in a poor user experience. Therefore, there is an urgent need to improve existing window cladding structures to meet the market's pressing demands for higher safety and performance in doors and windows. Summary of the Invention

[0005] To address the aforementioned problems, and especially the shortcomings of existing technologies, this invention provides a pressure line used on the inside of door and window glass that can solve these problems.

[0006] To achieve the above objectives, the present invention employs the following technical means:

[0007] A pressure line used on the inside of door and window glass includes a left frame, which is connected to a right frame via a connecting strip. The bottom of the right frame is connected to symmetrically distributed clips, and a triangular support frame is provided between the two sets of clips. One end of the triangular support frame is connected to a positive semi-circular hook groove, which is positively hooked to one set of clips. The other end of the triangular support frame is connected to a negative semi-circular hook groove, which is negatively hooked to another set of clips.

[0008] A further embodiment of this invention is that an auxiliary frame is connected to the bottom of the left frame.

[0009] A further embodiment of this invention is that the left frame, the subframe, and the right frame are all made of aluminum alloy.

[0010] A further embodiment of this invention is that the two ends of the connecting strip are respectively fixedly connected to the left frame and the right frame by bolts.

[0011] A further embodiment of this invention is that the clip and the right frame are integrally formed.

[0012] A further embodiment of this invention is that the end of the clip is provided with a chamfered structure.

[0013] A further embodiment of this invention is that the triangular support frame, the positive semi-circular hook groove, and the negative semi-circular hook groove are integrally manufactured.

[0014] A further aspect of this invention is that the thickness of the triangular support frame is greater than the thickness of the positive semicircular hook groove and the negative semicircular hook groove.

[0015] A further embodiment of this invention is that the inner walls of both the positive and negative semicircular hook grooves are provided with an anti-slip rubber layer.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model enhances wind pressure resistance: It abandons the traditional snap-on method and adopts a reverse hook method with a semi-circular hook and reinforced triangular support. When doors and windows are subjected to wind pressure, the structure composed of the triangular support frame, the positive semi-circular hook groove, and the negative semi-circular hook groove generates a force opposite to the wind pressure. This structural design effectively disperses the force generated by wind pressure, changing the previous situation where snap-on V-plates could not withstand strong wind pressure. It significantly improves the overall wind pressure resistance of the pressure line, effectively ensuring the stable fixation of door and window glass in severe weather, reducing the risk of glass breakage and detachment, and significantly enhancing the safety of doors and windows.

[0018] 2. This utility model enhances structural stability and robustness: The subframe connected to the bottom of the left frame strengthens the connection between the left frame and the door / window frame, making the quilting line more tightly integrated with the overall door / window structure. Simultaneously, the triangular support frame, the positive semi-circular hook groove, and the negative semi-circular hook groove are integrally manufactured. This one-piece molding design avoids loosening issues caused by weak connections between components. Compared to traditional quilting line structures, its overall strength and reliability are greatly improved. This stable and robust structure not only adapts to the needs of different environmental conditions but also extends the service life of the door / window quilting line and reduces subsequent maintenance costs.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] As shown in Figure 2, a pressure line used on the inside of door and window glass includes a left frame 1. The left frame 1 is connected to a right frame 4 via a connecting strip 3. The bottom of the right frame 4 is connected to symmetrically distributed clips 5. A triangular support frame 6 is provided between the two sets of clips 5. One end of the triangular support frame 6 is connected to a positive semi-circular hook groove 7, which is positively hooked to one set of clips 5. The other end of the triangular support frame 6 is connected to a negative semi-circular hook groove 8, which is negatively hooked to another set of clips 5.

[0026] Working principle

[0027] Overall frame structure: The inner edge of the window glass is composed of the left frame 1 and the right frame 4 as the main frame. The left frame 1 is connected to the right frame 4 through the connecting strip 3 to form a stable basic frame.

[0028] Key connecting components: Symmetrically distributed locking pins 5 are located at the bottom of the right frame 4, which are crucial connecting components for achieving the pressure line function. A triangular support frame 6 is positioned between the two sets of locking pins 5. One end of the triangular support frame 6 connects to a positive semi-circular hook groove 7, which hooks into one set of locking pins 5; the other end connects to a negative semi-circular hook groove 8, which hooks into the other set of locking pins 5. This unique connection method, compared to traditional snap-fit ​​methods, creates a force opposite to wind pressure. When the door or window is subjected to wind pressure, the pressure is transmitted through the glass to the pressure line. At this time, the hooking structure of the positive and negative semi-circular hook grooves 7 and 8 with the locking pins 5, combined with the triangular support frame 6, effectively disperses the pressure, resists the impact of wind pressure on the pressure line, improves the overall wind pressure resistance of the pressure line, and ensures the stable fixation of the door and window glass.

[0029] Example 2

[0030] As shown in Figure 2, a pressure line used on the inside of door and window glass includes a left frame 1. The left frame 1 is connected to a right frame 4 via a connecting strip 3. The bottom of the right frame 4 is connected to symmetrically distributed clips 5. A triangular support frame 6 is provided between the two sets of clips 5. One end of the triangular support frame 6 is connected to a positive semi-circular hook groove 7, which is positively hooked to one set of clips 5. The other end of the triangular support frame 6 is connected to a negative semi-circular hook groove 8, which is negatively hooked to another set of clips 5.

[0031] The bottom of the left frame 1 is connected to the sub-frame 2.

[0032] The advantages of the above settings are:

[0033] Enhanced connection stability: Subframe 2 increases the contact area and connection points between the left frame 1 and the door / window frame, making the connection between the pressure line and the door / window frame tighter and more secure. When subjected to external forces such as wind pressure, it can better transfer the force borne by the pressure line to the door / window frame, preventing the pressure line from loosening or even falling off due to weak connection, thus ensuring the stability of the fixed door / window glass.

[0034] Enhancing overall structural strength: The subframe 2 is connected to the left frame 1, which is equivalent to adding extra support to the pressure line structure, enhancing the rigidity and strength of the overall structure. It can assist components such as the triangular support frame 6, the positive semi-circular hook groove 7, and the negative semi-circular hook groove 8 in resisting external forces such as wind pressure, so that the pressure line can maintain good structural integrity in complex environments, improving the safety and reliability of doors and windows.

[0035] Easy to install and adjust: Multiple evenly distributed mounting holes can be set on the side of the subframe, which makes it easy for installers to accurately install the pressure line onto the door and window frame using bolts and other connectors. At the same time, fine-tuning can be made according to actual needs during the installation process to ensure the accuracy of the pressure line installation position, thereby improving installation efficiency and quality.

[0036] Adaptable to different door and window frames: Different door and window frames may vary in structure and size. The presence of the sub-frame 2 allows the door and window trim to better adapt to various door and window frames. By adjusting the connection method and position of the sub-frame 2 with the door and window frame, the trim can be made to fit closely with different types of door and window frames, expanding the product's applicability.

[0037] The left frame 1, the sub-frame 2, and the right frame 4 are all made of aluminum alloy.

[0038] The advantages of the above settings are:

[0039] High strength and lightweight characteristics: Aluminum alloy has high strength, ensuring that the left frame 1, sub-frame 2, and right frame 4 can effectively withstand the weight of the glass and external forces such as wind pressure in the door and window cladding structure, preventing deformation or damage and ensuring the safety and stability of the doors and windows. At the same time, aluminum alloy has a low density and is a lightweight material, reducing the overall weight of the door and window cladding compared to other metals. This reduces labor intensity during installation and the load on the door and window frames, which is beneficial for the long-term use of the doors and windows.

[0040] Excellent weather resistance: A dense oxide film naturally forms on the aluminum alloy surface, giving it excellent corrosion and oxidation resistance. Whether exposed to humid and rainy environments or prolonged exposure to sunlight, the left frame 1, sub-frame 2, and right frame 4 are not prone to rusting, fading, or aging, significantly extending the service life of the door and window moldings, reducing later maintenance and replacement costs, and maintaining the aesthetic appearance and stable performance of the doors and windows.

[0041] The two ends of the connecting strip 3 are fixedly connected to the left frame 1 and the right frame 4 respectively by bolts.

[0042] The advantages of the above settings are:

[0043] Easy and efficient installation: Bolt fixing is simple to operate. Construction workers do not need complicated skills or professional tools. By simply tightening the bolts, the connecting strip 3 can be quickly assembled with the left frame 1 and the right frame 4. This method greatly shortens the installation time and improves the installation efficiency of door and window trim, and is especially suitable for large-scale door and window production and installation scenarios.

[0044] The structure is robust and reliable: the bolts provide a strong tightening force, ensuring a secure connection between the connecting strip 3 and the left frame 1 and right frame 4. During the use of doors and windows, when faced with external forces such as wind pressure and vibration, the bolt-fixed structure effectively prevents loosening or displacement between components, ensuring the stability of the overall pressure line structure, thereby guaranteeing the safe fixation of the door and window glass and improving the safety and reliability of the doors and windows.

[0045] Easy disassembly and maintenance: When the door and window trim is damaged or needs repair, the connecting strip 3 can be easily removed by simply unscrewing the bolts, facilitating the inspection, repair, or replacement of the left frame 1, right frame 4, and the connecting strip 3 itself. This detachable connection method reduces maintenance difficulty, costs, and time, and improves the service life and maintenance convenience of doors and windows.

[0046] Flexible adjustment: The bolt-fixed connection allows for fine-tuning of the relative position and angle of the connecting strip 3 with the left frame 1 and right frame 4 during installation, adapting to the dimensions and installation requirements of different door and window frames. This flexibility enables the door and window trim to better match various door and window structures, expanding the product's applicability and improving its versatility and practicality.

[0047] The pin 5 and the right frame 4 are integrally molded structures.

[0048] The advantages of the above settings are:

[0049] Enhanced structural strength: The one-piece molded structure eliminates gaps and weak points between the locking pin 5 and the right frame 4. When the doors and windows are subjected to external forces such as wind pressure and the weight of the glass, this structure can distribute stress more evenly, preventing the locking pin 5 from detaching or the right frame 4 from being damaged due to insufficient strength at the connection points. Compared to splicing or welding connection methods, the one-piece molded locking pin 5 and right frame 4 have higher overall strength, effectively improving the door and window pressure line's ability to resist external forces and ensuring the safety and stability of the doors and windows.

[0050] Enhanced stability: Since there is no risk of loosening, the one-piece molded clip 5 and right frame 4 maintain a stable connection throughout long-term use. Whether due to frequent opening and closing of doors and windows or in harsh environments, changes in the connection points will not affect the fixing effect of the pressure line on the glass, ensuring that the door and window glass remains in a stable installation state and reducing safety hazards caused by structural instability.

[0051] Example 3

[0052] As shown in Figure 2, a pressure line used on the inside of door and window glass includes a left frame 1. The left frame 1 is connected to a right frame 4 via a connecting strip 3. The bottom of the right frame 4 is connected to symmetrically distributed clips 5. A triangular support frame 6 is provided between the two sets of clips 5. One end of the triangular support frame 6 is connected to a positive semi-circular hook groove 7, which is positively hooked to one set of clips 5. The other end of the triangular support frame 6 is connected to a negative semi-circular hook groove 8, which is negatively hooked to another set of clips 5.

[0053] The end of the pin 5 is provided with a chamfered structure.

[0054] The advantages of the above settings are:

[0055] Easy to install: The chamfered structure creates an inclined transition surface at the end of the clip 5, which acts as a guide when hooking the clip 5 with other components. Installers can easily insert the clip 5 into the corresponding position without precise alignment, reducing installation difficulty, time and effort, and improving installation efficiency, making it especially suitable for large-scale door and window production and installation scenarios.

[0056] Enhanced safety: The ends of un-beveled clips are typically sharp, posing a safety hazard if accidentally touched during installation or use, potentially causing cuts to the skin of operators or users. The beveled structure eliminates these sharp edges, effectively preventing accidental cuts and ensuring personnel safety, making door and window trim installation and daily use safer and more reliable.

[0057] Protecting structural components: During installation, the sharp end of the clip 5 may scratch or damage the mating parts, affecting their precision and lifespan. The chamfered structure makes the end of the clip 5 smooth, reducing friction and wear on other components during installation, lowering the risk of component damage, thereby extending the lifespan of all components of the door and window trim, and ensuring the stability and reliability of the entire door and window system.

[0058] The triangular support frame 6, the positive semi-circular hook groove 7, and the negative semi-circular hook groove 8 are made as one piece.

[0059] The advantages of the above settings are:

[0060] Enhanced overall structural strength: The one-piece manufacturing eliminates gaps and weak points between components, allowing the triangular support frame 6, the positive semi-circular groove 7, and the negative semi-circular groove 8 to form a complete load-bearing unit. When doors and windows are subjected to external forces such as wind pressure, this structure can more evenly distribute stress, preventing structural damage due to insufficient strength at joints. Compared to splicing or welding, the one-piece structure has higher strength and rigidity, effectively improving the wind pressure resistance of the pressure line and the overall load-bearing capacity, ensuring the stable installation of door and window glass.

[0061] Enhanced structural stability: Because there is no risk of loosening between components, the one-piece construction maintains a stable connection throughout long-term use. Whether frequently opening and closing doors and windows or in harsh environments, changes in component connections will not affect the glazing bead's hold on the glass. This stability ensures reliable operation of doors and windows under various conditions, reducing safety hazards caused by structural instability and improving their safety and reliability.

[0062] The thickness of the triangular support frame 6 is greater than the thickness of the positive semi-circular hook groove 7 and the negative semi-circular hook groove 8.

[0063] The advantages of the above settings are:

[0064] Enhanced support performance: The triangular support frame 6, as the main support structure, provides stronger support due to its greater thickness. In doors and windows, it can better withstand the weight of the glass and external wind pressure, ensuring the stability of the entire structure and preventing glass deformation, breakage, or damage to the overall door and window structure due to insufficient support.

[0065] Optimized stress distribution: The thicker triangular support frame 6 can more effectively disperse the pressure from the glass and other components. When subjected to external forces, it can evenly transmit the force throughout the entire structure, avoiding stress concentration in certain areas, thereby extending the service life of various door and window components and improving the safety and reliability of doors and windows.

[0066] Both the positive semi-circular hook groove 7 and the negative semi-circular hook groove 8 have an anti-slip rubber layer on their inner walls.

[0067] The advantages of the above settings are:

[0068] Enhanced friction: The rough surface of the anti-slip rubber layer significantly increases the friction between the object and the surface being fixed. When used to fix components such as glass, it effectively prevents the glass from sliding within the groove, ensuring that the glass remains in the correct position even when doors and windows are subjected to external forces such as vibration or wind pressure, thus improving the reliability of the fixation.

[0069] Protecting the fixed object: The soft rubber layer prevents the hard material of the groove from directly contacting the fixed object such as glass, preventing scratches, wear or indentations on its surface during installation or use, and protecting the integrity and appearance quality of the fixed object.

[0070] Noise reduction: During the opening and closing of doors and windows, the rubber layer can act as a buffer and shock absorber, reducing collision and friction noise between components, making the use of doors and windows quieter and more comfortable.

[0071] Improved sealing: Rubber has a certain degree of elasticity, which can fill the tiny gaps between the groove and the fixed object, thus playing a sealing role and preventing dust, rainwater and other external substances from entering the interior of the doors and windows, thereby improving the sealing and waterproof and dustproof performance of the doors and windows.

[0072] The examples provided in this utility model are not intended to limit the implementation methods. Those skilled in the art will recognize that various variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementation methods here, and any obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
