Description
Technical Field
[0001] This utility model relates to the field of building door and window technology, and in particular to a sealing monitoring structure for heat-insulating and energy-saving doors and windows. Background Technology
[0002] The sealing performance of insulated and energy-saving doors and windows directly affects living comfort and energy consumption. After long-term use, the sealing strips are prone to aging and wear, and the window sash may also fail to seal due to installation deviation or deformation. Once the seal is faulty, it will cause indoor and outdoor air circulation, significantly reducing the thermal insulation effect of doors and windows and increasing the energy consumption of air conditioning, heating and other equipment.
[0003] Most of the thermal insulation and energy-saving doors and windows on the market currently lack a dedicated sealing monitoring structure. Users can only indirectly judge the sealing status by sensing changes in indoor temperature and detecting air leaks. Some monitoring devices also rely on electronic sensors, batteries, or external power sources, which are relatively complex in structure, have high manufacturing and maintenance costs, are prone to failure in outdoor high and low temperature and humid environments, and have a short service life. They are difficult to adapt to the mass application needs of ordinary consumer doors and windows and cannot meet users' needs for a simple, reliable, and long-term stable sealing monitoring method.
[0004] To address the aforementioned issues, this utility model document proposes a sealing performance monitoring structure for thermal insulation and energy-saving doors and windows. Utility Model Content
[0005] This utility model provides a sealing monitoring structure for thermal insulation and energy-saving doors and windows, which solves the shortcomings of existing technology, such as the lack of simple and reliable sealing monitoring methods for existing doors and windows, or the complex monitoring structure, easy failure, and high maintenance cost.
[0006] This utility model provides the following technical solution:
[0007] A sealing performance monitoring structure for thermally insulated and energy-saving doors and windows includes:
[0008] A rectangular frame has an installation groove at the bottom of its inner wall. An installation block is fixedly installed at the bottom of the inner wall of the installation groove. A horizontally placed cylindrical tube is fixedly installed at the top of the installation block. A matching piston block is slidably installed inside the cylindrical tube. A red warning ball is fixedly installed at the center of one side of the piston block.
[0009] In one possible design, two sets of laminated glass are symmetrically fixed to the inner wall of the rectangular frame, and a matching sealing strip is fixed to the corner where the outer wall of each set of laminated glass meets the rectangular frame.
[0010] In one possible design, a miniature compression spring is provided between the piston block and the cylindrical cylinder. Corresponding abutments are fixedly provided at both ends of the miniature compression spring. One side of one abutment is fixed to the inner wall end of the cylindrical cylinder by adhesive, and one side of the other abutment is fixed to the other end of the piston block by adhesive.
[0011] In one possible design, the cylindrical tube has an unclosed display opening on its side wall, and the mounting groove has a display hole with embedded glass on its side wall.
[0012] In one possible design, the display hole is aligned with the display opening.
[0013] In one possible design, the red warning ball is not exposed inside the display opening when the micro-compression spring is in the contracted state, and gradually exposed inside the display opening when the micro-compression spring is in the extended state.
[0014] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.
[0015] The working principle and usage process of this technical solution are as follows:
[0016] In the initial sealed state, the two sets of laminated glass symmetrically fixed to the inner wall of the rectangular frame form a sealed cavity through the sealing strip at the corner between the outer wall and the rectangular frame, which is the core sealing area of the door and window. This sealed cavity is preset with a stable air pressure (dry negative pressure or inert gas slight positive pressure) to form a fixed pressure difference with the outside atmosphere. This pressure difference acts on the piston block in the cylindrical tube, pushing the piston block to move away from the display opening, thereby compressing the micro compression spring between the cylindrical tube and the piston block. The two ends of the compression spring are glued to the end of the inner wall of the cylindrical tube and the other end of the piston block respectively through abutments to ensure stable force during the compression process. At this time, the micro compression spring is in a contracted state, and the red warning ball fixed in the center of one side of the piston block is not exposed in the unsealed display opening on the side wall of the cylindrical tube. The user cannot observe the red warning ball through the display hole of the glass embedded in the side wall of the mounting groove, thus determining that the sealing performance of the door and window is intact.
[0017] In the micro-leakage warning state, when a micro-leak occurs in the sealed cavity due to aging, wear, or slight deformation of the window sash caused by the sealing strip, the preset air pressure inside the cavity gradually approaches the external atmospheric pressure. The pressure difference driving force inside and outside the cavity gradually decreases, and the micro-compression spring begins to slowly extend under its own elastic restoring force. Through the abutments at both ends, it drives the piston block to move towards the display opening side along the sliding direction inside the cylindrical tube. As the piston block moves, the red warning ball on one side gradually approaches the display opening and is partially exposed inside the display opening. Since the display opening is aligned with the display hole on the mounting groove, the user can see through the display hole... The embedded glass reveals a partially red area, indicating that the sealing performance of the doors and windows has begun to decline. It is necessary to monitor subsequent changes in the sealing status. When the sealing leakage intensifies and the air pressure inside and outside the sealed cavity is completely balanced and the pressure difference disappears, the micro spring is no longer constrained by the pressure difference and extends to its natural state. This pushes the piston block to move to the extreme position of the cylindrical tube near the display opening. At this time, the red warning ball is fully exposed inside the display opening. Users can clearly observe the complete red warning ball through the display hole, triggering a clear red warning visual effect. This directly indicates that the door and window seal has completely failed and timely maintenance is required.
[0018] This utility model has the following beneficial effects:
[0019] This invention relies on the pressure difference between the sealed cavity and the outside environment and the elastic restoring force of the miniature compression spring to achieve transmission throughout the entire monitoring process. It requires no external power supply, built-in battery, or complex electronic sensors and is entirely a purely mechanical structure. All components are standardized or easily processed parts (such as the miniature compression spring, which is a standardized part, and rectangular frames and cylindrical tubes, which can be made through conventional hardware processing). The processing difficulty is low and the cost is controllable. It not only avoids the problems of easy aging and failure of electronic components, but also achieves long-term passive and maintenance-free use, which greatly reduces the user's use and maintenance costs and meets the mass promotion needs of consumer door and window products.
[0020] In this utility model, the core monitoring components (cylindrical tube, piston block, miniature compression spring, etc.) are integrated into the mounting groove at the bottom of the inner wall of the rectangular frame. The cylindrical tube is fixed by the mounting block. The structure is compact and does not occupy extra space for doors and windows, nor does it affect the opening and closing function of doors and windows or the overall aesthetics.
[0021] This invention provides an early warning system by checking whether a red warning ball is exposed. With the alignment of the display opening and the display hole, users can intuitively judge the sealing status simply by looking at the embedded glass in the display hole, without needing any professional knowledge or tools.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.
[0030] In one embodiment:
[0031] Please refer to Figure 1-4 A sealing monitoring structure, comprising:
[0032] The rectangular frame 1 has a pre-drilled mounting groove 4 at the bottom of its inner wall. The size of the mounting groove 4 is compatible with the cylindrical tube 5 and mounting block 6 to be assembled later, ensuring that there is no looseness after the components are assembled. The mounting block 6 is made of stainless steel and is fixed to the bottom of the inner wall of the mounting groove 4 with bolts. The bolts are cross-head countersunk bolts to avoid the surface protruding after installation and affecting the assembly of other components. The cylindrical tube 5 is placed horizontally and its bottom is fixed to the top of the mounting block 6 by welding. The weld joint needs to be ground to ensure that the connection surface is flat. The cylindrical tube 5 is made of stainless steel and its inner wall is precision machined to ensure that the inner wall is smooth and burr-free, providing a stable foundation for the sliding of the piston block 7.
[0033] The outer diameter of the piston block 7 and the inner diameter of the cylindrical cylinder 5 are in clearance fit. The clearance is controlled within a reasonable range to ensure that the piston block 7 can slide smoothly and reduce the impact of gas leakage on monitoring. A layer of high-temperature resistant grease is uniformly coated on the outer wall of the piston block 7. The grease is lithium-based and can adapt to various outdoor temperature environments, preventing wear caused by the sliding between the piston block 7 and the inner wall of the cylindrical cylinder 5, while improving the stability of the transmission. The red warning ball 8 is fixed in the center of one side of the piston block 7 by adhesive. Weather-resistant epoxy adhesive is used to ensure that the red warning ball 8 will not fall off during long-term use.
[0034] The miniature compression spring 10 is connected to two abutment plates 11 at both ends. One side of one abutment plate 11 is fixed to the inner wall end of the cylindrical tube 5 by adhesive, and the other side of the abutment plate 11 is fixed to the other end of the piston block 7 by the same adhesive. When adhesive is applied, it is necessary to ensure that the abutment plate 11 is perpendicular to the axis of the miniature compression spring 10 to avoid the miniature compression spring 10 from shifting when it extends or retracts. After assembly, when the miniature compression spring 10 is in its natural state, the piston block 7 is close to one end of the cylindrical tube 5, and the red warning ball 8 is located inside the cylindrical tube 5 and is not exposed.
[0035] An unclosed display opening 9 is made on the side wall of the cylindrical tube 5. The size of the display opening 9 is slightly larger than the diameter of the red warning ball 8, ensuring that the red warning ball 8 can be clearly seen when fully exposed. A display hole 12 is made on the side wall of the mounting groove 4. Tempered glass is embedded in the display hole 12 and fixed in the display hole 12 with sealant to ensure the sealing of the display hole 12. During assembly, the position of the cylindrical tube 5 needs to be adjusted so that the display opening 9 and the display hole 12 are completely aligned, ensuring that the user can clearly observe the status of the red warning ball 8 in the display opening 9 through the tempered glass of the display hole 12.
[0036] Two sets of laminated glass 2 are symmetrically installed on the inner wall of the rectangular frame 1. The laminated glass 2 is conventional architectural laminated glass and is fixed to the preset installation position on the inner wall of the rectangular frame 1 with glass glue. Matching sealing strips 3 are installed at the angle between the outer wall of each set of laminated glass 2 and the rectangular frame 1. The sealing strips 3 are made of EPDM rubber, which has good aging resistance and sealing performance. During installation, the sealing strips 3 are embedded into the preset strip groove to ensure that the sealing strips 3 are tightly fitted with the laminated glass 2 and the rectangular frame 1 to form a sealed cavity. This sealed cavity is the core sealing area of the door and window.
[0037] After the sealed cavity is formed, it needs to be pressure preset. Inert gas can be injected into the cavity through the air inlet reserved in the rectangular frame 1 to form a slight positive pressure. After inflation, the air inlet is sealed with a sealing plug. At this time, the air pressure in the sealed cavity forms a fixed pressure difference with the outside atmosphere. This pressure difference acts on the piston block 7 in the cylindrical tube 5, pushing the piston block 7 to move away from the display port 9, thereby compressing the micro spring 10 until the pressure difference and the elastic force of the micro spring 10 reach equilibrium. At this time, the micro spring 10 is in a contracted state, and the red warning ball 8 is not exposed in the display port 9. The user cannot observe the red warning ball 8 through the tempered glass of the display hole 12, indicating that the sealing performance of the door and window is good.
[0038] When the sealing strip 3 experiences micro-leakage in the sealed cavity due to aging, wear, or slight deformation of the window sash, the preset air pressure inside the cavity gradually approaches the external atmospheric pressure. The pressure difference driving force inside and outside the cavity gradually decreases, and the miniature compression spring 10 begins to slowly elongate under its own elastic restoring force. Through the abutment plates 11 at both ends, it drives the piston block 7 to move towards the display opening 9 along the sliding direction inside the cylindrical tube 5. Since the outer wall of the piston block 7 is coated with grease, the entire sliding process is smooth and without jamming. As the piston block 7 moves, the red warning ball 8 gradually approaches the display opening 9 and is partially exposed inside the display opening 9. The user can see through the tempered glass of the display hole 12. A partially red area can be observed, indicating that the sealing performance of the doors and windows has begun to decline. When the sealing leakage intensifies and the air pressure inside and outside the sealed cavity is completely balanced and the pressure difference disappears, the miniature spring 10 is no longer constrained by the pressure difference and extends to its natural state, pushing the piston block 7 to move the cylindrical tube 5 to the limit position close to the display port 9. At this time, the red warning ball 8 is completely exposed inside the display port 9. The user can clearly observe the complete red warning ball 8 through the tempered glass of the display hole 12, indicating that the door and window seal has completely failed and needs to be maintained in time. After the maintenance is completed, the air pressure of the sealed cavity is preset again, and the monitoring structure can return to normal working state.
[0039] This application can be used for monitoring the sealing performance of doors and windows, or for other fields applicable to this application.
