Description

Technical Field

[0001] The invention belongs to the technical field of door and window air tightness detection, relates to a technology for improving the sealing performance of a sealing film at a corner of a window frame or a door frame, and specifically relates to a door and window air tightness detection device. Background Art

[0002] Door and window air tightness testing refers to the process of evaluating and measuring the air tightness of doors and windows in the closed state through specific testing equipment and methods. Specifically, it is to apply positive or negative pressure to the inside of the sealed doors and windows, and monitor the amount of air penetration or leakage through the gaps of the doors and windows to determine whether the sealing of the doors and windows meets the set standards. This test is usually used to evaluate the insulation performance of doors and windows when facing external airflow, wind pressure or temperature difference, to ensure key indicators such as energy efficiency, comfort and weather resistance inside the building.

[0003] In the actual operation of door and window air tightness testing, the edges of door and window frames and the inner edges of corners are usually relatively weak areas of sealing performance. The corners of door and window frames have a certain curvature, and the inner edges usually present complex geometric shapes, which makes it difficult for the sealing film to achieve uniform and tight fit during the test, resulting in an increased possibility of gas leakage. Therefore, in air tightness testing, how to effectively improve the sealing performance of the inner edges of corners has become a technical problem that needs to be solved urgently.

[0004] Traditional door and window air tightness testing equipment mainly achieves the closure of the test area by pressing a sealing film along the edge of the door and window frame. However, at the corners, the sealing film often cannot fit completely with the window frame due to the lack of sufficient pressing force or adaptive structure, forming a "leak point" with insufficient air tightness. This "leak point" will cause the test gas to leak out, making the test data inaccurate, and may even lead to a wrong assessment of the air tightness level of the door and window. In addition, the complexity of the corner area also brings certain challenges to the design of existing testing equipment. The traditional fixed pressing method is difficult to adapt to door and window frames of different shapes and sizes, especially showing great limitations at the corners. Summary of the invention

DETAILED DESCRIPTION

[0020] 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 embodiments are only part of the embodiments of the present invention, not all of the 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.

[0021] See also Figures 1 to 10 As shown, the specific embodiments provided by the present invention are as follows: like Figures 1 to 4 As shown, the first embodiment of the present invention provides a door and window air tightness detection device, comprising: Detection system; A sealing membrane 1 having an air inlet port 101 through which the detection system delivers gas; A mounting assembly 2 having a first mounting end surface 201 and a second mounting end surface 202; The first mounting end surface 201 and the second mounting end surface 202 are side wall surfaces of the mounting component 2; Furthermore, the first mounting end surface 201 and the second mounting end surface 202 are perpendicular; A first pressing component 3, connected to the first mounting end surface 201 and the second mounting end surface 202; A second pressing component 4 is installed at a connection position between the first installation end surface 201 and the second installation end surface 202; The first pressing component 3 is configured to press the edge of the sealing film 1 to the horizontal or vertical inner edge of the window frame or door frame; The second pressing component 4 is configured to press the edge of the sealing film 1 to the inner edge of the corner of the window frame or door and window; Wherein, the second pressing component 4 at least forms a pressing cavity 20241; The pressure P1 of the pressing cavity 20241 is positively correlated with the force F exerted by the second pressing component 4 on the edge of the sealing film 1; Moreover, the pressure P1 of the pressing cavity 20241 is positively correlated with the pressure P2 of the space enclosed by the sealing film 1 .

[0022] In this embodiment, the detection system includes an air delivery pump and a pressure detection device. The air delivery pump is used to deliver gas through the air delivery port of the sealing film 1 through the air delivery pipeline to the enclosed space enclosed by the sealing film 1 and the door frame or window frame.

[0023] When installing, the installation component 2 is placed in a door frame or a window frame, and the edge of the sealing film 1 is pressed and sealed by the first pressing component 3 and the second pressing component 4 .

[0024] Specifically, the first pressing component 3 is used to press-seal the sealing film 1 to the horizontal or vertical inner edge of the door frame or window frame. It presses the edge of the sealing film 1 to the inner edge by applying pressure perpendicular to the inner edge.

[0025] The second pressing component 4 is used to press seal the sealing film 1 on the inner edge of the corner of the door frame or window frame. At least one pressing cavity 20241 is formed in the second pressing component 4. By controlling the pressure P1 in the pressing cavity 20241, it is positively correlated with the force F applied by the second pressing component 4 to the edge of the sealing film 1, thereby realizing dynamic adjustment of the force F. Through this design, it can be ensured that the edge of the sealing film 1 in the corner area obtains appropriate pressing force, effectively reducing gas leakage and improving the accuracy of detection.

[0026] At the same time, the pressure P1 of the pressing cavity 20241 also maintains a positive correlation with the pressure P2 of the space enclosed by the sealing film 1. The purpose of this design is that during the airtightness test, when the gas pressure in the internal space of the sealing film 1 changes, the pressure of the pressing cavity 20241 can be adjusted accordingly, thereby ensuring that the pressing effect of the sealing film 1 in the entire test area is uniform and consistent, further improving the adaptability of the equipment and the reliability of the test.

[0027] In a specific embodiment, in order to achieve a dynamic balance of gas pressure between the space enclosed by the sealing film 1 and the pressure-coated cavity 20241, a connecting hole 20243 is designed on the inner wall of the pressure-coated cavity 20241, facing the space enclosed by the sealing film 1. The connecting hole 20243 allows the gas in the space to enter the pressure-coated cavity 20241 synchronously, thereby achieving free flow of gas, so that the pressure in the pressure-coated cavity 20241 can respond to the change of pressure in the space in a timely manner.

[0028] By setting the connecting hole 20243, the pressure of the pressing cavity 20241 can be synchronized with the pressure of the space enclosed by the sealing film 1 in real time. When the gas pressure in the space enclosed by the sealing film 1 rises during the detection process, the gas can quickly enter the pressing cavity 20241 through the connecting hole 20243, thereby increasing the pressure of the pressing cavity 20241. In this way, the force exerted by the pressing cavity 20241 on the edge of the sealing film 1 is also increased accordingly, so that the sealing film 1 always keeps a tight fit at the edges and corners, reducing the possibility of gas leakage.

[0029] The advantage of this design is that, through the synchronous entry of gas and pressure balance, the pressure effect of the pressure-covering cavity 20241 is consistent with the pressure change in the space, further improving the adaptability and accuracy of the detection equipment. The configuration of the connecting hole 20243 ensures that the pressure-covering cavity 20241 can automatically adjust according to different detection pressures, so that the effective sealing of the corners and edge areas can be maintained under various pressure conditions, thereby improving the reliability of the equipment in the air tightness detection of doors and windows.

[0030] In a specific embodiment, in order to more accurately control the gas flow in the pressure-coated cavity 20241, a gas flow control member is specially provided. The gas flow control member is installed at the connecting hole 20243 and is used to adjust the amount of gas flow entering between the enclosed space of the sealing film 1 and the pressure-coated cavity 20241, so as to achieve more accurate airtightness control under different testing conditions.

[0031] The design of the airflow control component can be set according to specific needs, for example, a valve or a flow controller can be used to control the rate at which the gas enters the pressure-coated cavity 20241. When the pressure P2 of the space enclosed by the sealing film 1 changes, the airflow control component can adjust the rate at which the gas flows into the pressure-coated cavity 20241 to ensure that the pressure P1 in the pressure-coated cavity 20241 can smoothly and accurately follow the changes in P2, thereby controlling the force F exerted by the pressure-coated cavity 20241 on the edge of the sealing film.

[0032] The advantage of the airflow control member is that it can avoid excessive or insufficient pressure in the pressure-covering cavity 20241 when the pressure changes rapidly, thereby preventing the sealing film from sealing unevenly at the corners and edge areas. This airflow control enables the pressure-covering cavity 20241 to respond quickly to pressure adjustment when needed, but maintain a stable force in a stable state, further improving the reliability and adaptability of the airtightness testing equipment, ensuring that the equipment can accurately test the airtightness of doors and windows under various pressure environments.

[0033] Furthermore, when pressing the sealing film 1 at the corner, the prior art usually relies on manual tools such as a wrench for adjustment. This method requires the operator to rotate the wrench perpendicular to the window frame or door frame to ensure that the sealing film 1 is tightly fitted with the window frame or door frame. However, during this operation, the wall at the corner often physically interferes with the operating arm or wrench, resulting in the limitation of the pressing action, resulting in the following problems: Due to the limited operating space at the corners, the wrench cannot exert enough force when turning to achieve full compression of the sealing film 1. Especially at the corners, the sealing film 1 often requires higher pressure to fit tightly with the edge of the window frame or door frame. However, due to the limited operating space at the corners, the rotation range of the wrench is hindered by the wall, resulting in uneven compression force, which ultimately affects the sealing effect.

[0034] It is difficult to operate at corners, especially in narrow or complex structural environments, where the operating angle of the wrench is greatly limited. The operator has to apply force at an unnatural angle, which increases the complexity and difficulty of the operation. In addition, during the rotation of the wrench, the operating arm frequently collides with the wall or other obstacles, which not only affects the smooth progress of the pressing operation, but also increases the fatigue and inconvenience of the operation.

[0035] Based on this, the second pressing assembly 4 includes a second driving member 401 and a second pressing arm 402; The second driving member 401 is controlled to rotate along the first direction to drive the second pressing arm 402 to move toward or away from the inner edge of the corner; Furthermore, the plane M where the first direction is located is parallel to the plane where the door frame or window frame is located.

[0036] The second driving member 401 has a rotational motion along the first direction, and the plane M in the first direction is parallel to the plane in which the door frame or window frame is located. That is, the operator can cause the second pressing arm 402 to press the sealing film 1 on the corner of the door frame or window frame by operating in the first direction, and the operation process will not form motion interference with the door frame or window frame, thereby ensuring that the operator can make full pressing adjustment, ensure accurate adjustment of the pressing force, and ultimately ensure the airtightness of this position.

[0037] Furthermore, the second driving member 401 is a rotational motion. Compared with electric linear devices such as cylinders, it can meet the space requirements at the corners of door frames or window frames. The reason is that the electric linear device needs to reserve enough space to meet its telescopic or linear displacement requirements. In order to complete a complete pressing operation, the electric linear device must have an available space equal to its stroke. This often does not have enough space in some narrow areas or complex structures (such as the corners of door and window frames), resulting in these devices not being able to work properly or being difficult to install.

[0038] During installation, the electric linear actuator needs to ensure that the full length of its piston rod can be fully extended and retracted, while also considering the surrounding fixing and supporting structures. This requires that more operating space must be reserved during the design of the electric linear actuator, which is a significant disadvantage, especially in a compact operating environment.

[0039] Since the motion path of the electric linear device is a straight line, especially during operation, the device requires a large travel space. If the design with the surrounding structure is not reasonable, it will increase the risk of physical interference with walls, other equipment or workpieces. This interference problem is particularly prominent in areas with small spaces such as the corners of door and window frames, which may limit operation or affect accuracy.

[0040] Moreover, when faced with complex geometries or limited installation locations, linear motion is difficult to effectively adapt to curves or irregular spaces and requires additional design or mechanical support, which further increases operational complexity.

[0041] Based on this, this embodiment uses the form of rotational drive to enable the second driving member 401 to operate flexibly in a narrow space, especially showing better adaptability at the corners of door frames or window frames.

[0042] In summary, this embodiment solves the limitation and interference problems of the electric linear device when operating in a space-constrained, especially at the corner of a door frame or window frame, by adopting the second driving member 401 driven by rotation. Since the rotating driving member does not need to reserve a long travel space, it can better adapt to narrow areas and complex structures. This design makes the pressing operation more flexible and avoids the risk of physical interference caused by space limitations.

[0043] The operation mode of rotating the second driving member 401 allows the sealing film 1 to be accurately pressed in a limited space, which not only improves the overall applicability of the device, but also ensures that the sealing film 1 can obtain sufficient pressing force at each edge and corner in a scene with a complex geometric shape, thereby ensuring the accuracy of airtightness detection. Through such a structural design, the present invention improves the flexibility, reliability and efficiency of the device, and is particularly suitable for environments with complex spaces and limited installation locations.

[0044] like Figures 5 to 7 As shown, the second embodiment of the present invention provides a door and window air tightness detection device, and based on the first embodiment, the second pressing component 4 includes: A second connecting member 403, the second connecting member 403 is mounted to the second mounting end surface 202 and is perpendicular to the second mounting end surface 202; Wherein, the second connecting member 403 forms a displacement cavity 4031 parallel to the plane M; Furthermore, the second pressing arm 402 is controlled by the second driving member 401 to move along the displacement cavity 4031 .

[0045] In this embodiment, the second connecting member 403 is installed on the second mounting end surface 202 and is perpendicular to the mounting end surface. The vertical mounting form also helps to accurately apply pressure during the pressing process to avoid deviation.

[0046] A displacement cavity 4031 is formed in the second connecting member 403, and the displacement cavity 4031 is parallel to the plane M. This means that the second pressing arm 402 can be displaced in a plane parallel to the window frame or door frame, ensuring the directionality and accuracy of the pressing action.

[0047] Through the design of the displacement cavity 4031, the movement path of the second pressing arm 402 is effectively guided, avoiding irregular movement in the free space, so that the pressing arm always moves within the predetermined track. This design not only improves the pressing accuracy, but also ensures effective sealing film 1 pressing on the corners of doors and windows of different sizes and structures.

[0048] The third embodiment of the present invention provides a door and window air tightness detection device, and based on the previous embodiment, the second driving member 401 includes: Drive one and drive two; The driving part is mounted to the end surface of the second connecting member 403 parallel to the plane M; The second driving part is installed in the displacement cavity 4031; Furthermore, the first driving part and the second driving part are meshingly connected; The first driving part has a rotational motion along the first direction, so as to cause the second pressing arm 402 to move along the displacement cavity 4031 through the second driving part.

[0049] In this embodiment, by introducing the combination of the first driving part and the second driving part, the displacement control of the second pressing arm 402 is made more precise, and the operational flexibility and functionality of the device are enhanced.

[0050] Specifically, the second drive part is installed in the displacement cavity 4031, and its function is to directly control the movement path of the second pressing arm 402 in the displacement cavity 4031 through meshing connection with the first drive part. The positioning of the second drive part ensures that the pressing arm can move along the predetermined track, while providing more precise control for the entire system.

[0051] The first drive part generates mechanical motion through rotation, and the motion is further converted into controlling the smooth displacement of the second pressing arm 402 along the displacement cavity 4031 through meshing transmission with the second drive part. The advantage of meshing transmission is that it can accurately transmit torque and reduce energy loss in motion, ensuring smooth and efficient displacement.

[0052] Through this transmission structure, the rotation of the first drive can accurately control the movement of the second drive, thereby achieving fine adjustment of the displacement of the pressing arm. Especially in the complex operation at the corners of doors and windows8, the meshing transmission can ensure the accuracy of displacement and uniformity of pressing, avoiding sealing problems caused by discontinuous or unstable movement.

[0053] The movement of the driving part is a rotational movement along a first direction, which is parallel to the plane of the door and window frame. This design makes the operation of the driving part more in line with the overall structural requirements of the equipment, ensuring that there will be no interference with other parts of the window frame or door frame during the pressing process.

[0054] The second driving part is located in the displacement cavity 4031, and its meshing connection with the first driving part ensures that the second pressing arm 402 can move accurately along the track of the displacement cavity 4031. Due to the existence of the displacement cavity 4031, the movement path of the pressing arm is strictly limited, reducing the deviation in the movement and improving the uniformity of the pressing force.

[0055] The meshing transmission structure enables each rotation of the first drive to be accurately transmitted to the second drive, thereby ensuring the displacement accuracy of the pressing arm. This precise control is particularly suitable for pressing operations at the corners of doors and windows, and can provide a stable and continuous pressing force, thereby ensuring the airtightness of the sealing film 1 in these complex areas.

[0056] In a specific embodiment, the first driving part includes a rotating handle 4011 and a first driving gear 4012. The rotating handle 4011 is mounted on the end surface of the second connecting member 403 and is rotatable, and synchronously drives the first driving gear 4012 to rotate. The second driving part includes a second driving gear 4013, a threaded rod 4014, and a threaded seat 4015. The second driving gear 4013 is meshedly connected to the first driving gear 4012, the threaded rod 4014 is connected to the second driving gear 4013, and the threaded seat 4015 is installed on the threaded rod 4014. In addition, the second pressing arm 402 is connected to the threaded seat 4015.

[0057] like Figures 5 to 7 As shown, the fourth embodiment of the present invention provides a door and window air tightness detection device, and based on the previous embodiment, the second pressing arm 402 includes: An arm having a first connection end 4021 and a second connection end 4022; A head having a first pressing body 4023 and a second pressing body 4024; The first connection end 4021 is hinged to the second driving part; The second connecting end 4022 is hinged to the first pressing body 4023; Furthermore, the arm portion and the second driving portion have an included angle a smaller than 90°; The second pressing body 4024 is used for pressing the edge of the sealing film 1 , and the pressing cavity 20241 is arranged on the second pressing body 4024 .

[0058] In this embodiment, the second pressing arm 402 is further optimized, especially by introducing the hinged structure of the first connection end 4021 and the second connection end 4022, and the combination of the first pressing body 4023 and the second pressing body 4024, so that the pressing operation is more flexible and accurate. These design details are intended to improve the operating efficiency of the device in complex door and window frame structures, especially the pressing effect at corners.

[0059] Specifically, the first connection end 4021 is hinged to the second driving part. This hinge design gives the arm greater flexibility and can be flexibly adjusted according to the movement of the second driving part, so that the second pressing arm 402 can more easily perform pressing operations in complex door and window frame structures. The hinge point can enable the arm to rotate within a specific range, ensuring that its movement adapts to window frames or door frames of different shapes.

[0060] The hinge between the second connecting end 4022 and the first pressing body 4023 further enhances the flexibility of the pressing body, allowing the pressing body to accurately press according to the edge of the door and window frame to ensure uniform distribution of the pressing force. Especially in operations at corners, this design can ensure that the sealing film 1 is pressed tightly.

[0061] An angle a less than 90° is formed between the arm and the second driving part. This design enables the second covering arm 402 to better fit the shape of the window frame or door frame when applying the covering force, especially at the corners. The smaller angle can help the covering arm get closer to the edge, providing a more direct and effective covering force.

[0062] This embodiment adds a hinged structure of the first connection end 4021 and the second connection end 4022 to the second pressure covering arm 402, and designs an angle less than 90°, so that the device can more flexibly cope with various complex door and window frame structures during operation, especially at corners, and can achieve more accurate and uniform pressure covering force. Through this design, the device can improve the pressure covering effect in various complex operating environments, thereby improving the accuracy and efficiency of door and window air tightness detection.

[0063] like Fig. 9 As shown, specifically, the first pressing body 4023 is made of a rigid material; The second pressing body 4024 is made of flexible material; The portion where the second pressing body 4024 contacts the sealing film 1 is provided with the pressing cavity 20241 .

[0064] Specifically, the first pressing body 4023 is made of a rigid material, which ensures the structural strength and stability during the pressing process. The rigid material can withstand a large pressure, ensuring that the first pressing body 4023 can apply sufficient pressing force at the inner edge of the horizontal or vertical window frame to firmly press the sealing film 1 onto the window frame. The use of rigid materials can effectively prevent the pressing body from deforming during operation, ensuring uniform transmission and precise control of the pressing force.

[0065] The rigid design of the first pressing body 4023 is particularly suitable for pressing the horizontal or vertical edges of door and window frames, and can effectively overcome the uneven force distribution phenomenon that may occur when pressing a large area.

[0066] The second pressing body 4024 is made of a flexible material, which makes it more adaptable, especially when processing the corners of window frames or door frames, it can better fit irregular shapes. The flexible material has good deformation ability and can closely fit the edge of the sealing film 1 during pressing, and can ensure the tightness of pressing even in complex or curved window frame areas.

[0067] The flexible material also has the function of protecting the sealing film 1. Since pressure needs to be applied during the lamination process, the flexible material can buffer part of the pressure to prevent damage or tearing of the sealing film 1, especially under long-term or high-pressure conditions, the flexible material can effectively protect the integrity of the sealing film 1.

[0068] The portion of the second pressing body 4024 that contacts the sealing film 1 is provided with a pressing cavity 20241, which can produce a certain degree of flexible expansion under the action of pressure regulation, so that the second pressing body 4024 of the flexible material applies a controllable and uniform pressure to the edge of the sealing film at the corner, thereby achieving a better fitting effect. Due to the adaptability of the flexible material and the dynamic adjustment capability of the pressing cavity 20241, this design ensures that the sealing film in the corner area can obtain sufficient pressing force under various pressure environments, avoiding leakage or insufficient sealing.

[0069] like Fig.10 As shown, the fifth embodiment of the present invention provides a door and window air tightness detection device, and on the basis of the previous embodiment, includes: The sealing member 5 is attached to the inner edge of the corner of the window frame or the door and window; The edge of the sealing film 1 is pressed between the sealing member 5 and the second pressing body 4024; Furthermore, the sealing member 5 is made of flexible material.

[0070] In this embodiment, the sealing member 5 is designed to be attached to the inner edge of the corner of the window frame or door and window. The corner is a common weak point in airtightness testing. Due to the complexity of the structure, it is difficult to attach the sealing film 1 to these areas. By providing the sealing member 5, a better pressing base can be provided for the sealing film 1 to ensure the pressing effect of the sealing film 1 in these areas.

[0071] The edge of the sealing film 1 is pressed between the sealing member 5 and the second pressing body 4024. Through this dual effect, the sealing film 1 can achieve a more stable and uniform fit at the corner, thereby improving the airtightness.

[0072] The seal 5 is made of a flexible material, which enables it to adapt to various shapes and slight irregularities at the corners, ensuring a good fit with the inner edge of the window frame or door frame. The flexible material has the ability to deform and can be deformed appropriately according to the pressure during pressing, ensuring that each part of the sealing film 1 at the corner can be tightly pressed on the inner edge of the window frame.

[0073] During the pressing process, the flexible material can effectively buffer the pressure applied by the second pressing body 4024 to prevent the sealing film 1 from being damaged by excessive pressing force, and can also help the sealing film 1 to achieve uniform fitting under different pressures.

[0074] The flexible seal 5 can protect the sealing film 1 to a certain extent. Especially in a long-term high-pressure detection environment, the sealing film 1 may be worn or torn due to repeated stress. The buffering effect of the flexible seal 5 can effectively extend the service life of the sealing film 1.

[0075] Furthermore, the pressing cavity 20241 may contain a plurality of magnetic particles 20242, which can be arranged and distributed more stably under the action of a magnetic field. When the seal 5 is subjected to external pressure during the pressing process, the magnetic particles 20242 can move in the cavity, thereby automatically adjusting the pressing force according to the specific shape of the window frame or door frame, ensuring that the sealing film 1 can fit tightly at corners and other complex edges.

[0076] The magnetic particles 20242 can evenly distribute pressure under the action of the external magnetic field to prevent excessive or insufficient local pressure during the pressing process. In this way, the magnetic particles 20242 help ensure that the sealing film 1 can be subjected to uniform pressing force in a complex window frame structure, thereby improving the overall sealing effect.

[0077] The sealing member 5 is provided with an attraction groove 501, which is specially used to accommodate the attraction belt 502. The design of the attraction groove 501 can effectively control the movement trajectory of the magnetic particles 20242, so that they can better cooperate with the sealing film 1 during the pressing process. The existence of the attraction groove 501 provides space for the movement of the magnetic particles 20242, and also ensures that these particles will not move excessively or concentrate in a certain area, resulting in uneven pressing force distribution.

[0078] The attraction groove 501 helps to guide the flow of the magnetic particles 20242 during the lamination process, so that the magnetic particles 20242 can function more stably when affected by the magnetic attraction belt 502, ensuring that the magnetic particles 20242 can better fit on complex surfaces.

[0079] The attraction belt 502 is arranged in the attraction groove 501 and is made of a magnetic material. The attraction belt 502 attracts the magnetic particles 20242 through magnetic force, thereby keeping them within a certain range, ensuring that the particles will not weaken the sealing effect due to excessive flow during the pressing process. The magnetic attraction belt 502 can control the distribution and movement of the magnetic particles 20242, so that the sealing film 1 can fit the window frame or door frame more stably at the corner.

[0080] The magnetic attraction band 502 can enhance the adhesion of the sealing film 1 at the corners. Through the interaction between the magnetic particles 20242 and the attraction band 502, the sealing film 1 can better fit the window frame when subjected to external pressure, especially in areas with complex shapes or irregular structures. The magnetic attraction band 502 provides additional adhesion, further improving the airtightness.

[0081] The attraction belt 502 forms a wavy path, and this design increases the effective contact area of ​​the attraction belt 502, so that it can exert a more uniform attraction force on the magnetic particles 20242. The wavy path can distribute the magnetic field more widely by increasing the surface area of ​​the magnetic attraction belt 502, so that the magnetic particles 20242 can be more evenly distributed in the pressing cavity 20241, avoiding the situation where the magnetic particles 20242 are excessively concentrated in a certain local area.

[0082] The wavy path design not only increases the attraction range of the magnetic attraction belt 502, but also guides the magnetic particles 20242 to move along a specific trajectory, so that the sealing film 1 can continue to be subjected to uniform magnetic adsorption force during the entire pressing process, thereby ensuring the fitting effect of the sealing film 1 at the corners and the edges of the window frame.

[0083] It should be noted that the volume of the second pressing body 4024 occupied by the pressing cavity 20241 should not be too large, and can be regarded as a relatively thin layer, so as to avoid the problem of insufficient pressing force.

[0084] The sixth embodiment of the present invention provides a door and window air tightness detection device, and based on the previous embodiment, the first pressing component 3 includes: A first connecting member 301, mounted to the first mounting end surface 201 and the second mounting end surface 202; A first driving member 302, plugged into the first connecting member 301; A first pressing plate 303 connected to the first driving member 302; The first driving member 302 drives the first pressing plate 303 to move toward or away from the inner edge of the window frame or door frame.

[0085] In this embodiment, the first connecting member 301 is installed on the first mounting end surface 201 and the second mounting end surface 202, and plays the role of fixing the first pressing assembly 3. By connecting the first mounting end surface 201 and the second mounting end surface 202, the first connecting member 301 ensures the stability of the entire pressing assembly, avoiding operational errors caused by vibration or unstable structure during the pressing operation.

[0086] The first connecting member 301 serves as a supporting structure of the cladding system and can provide a solid foundation for subsequent cladding actions, ensure that the cladding plate remains stable during movement, and reduce irregular movement of the structure during the cladding process.

[0087] The first driving member 302 is connected to the first connecting member 301 by plugging. This design makes the driving member easier to install and disassemble, while improving the overall reliability of the pressing assembly. The plug-in design provides an efficient force transmission method, ensuring that the driving member can stably transmit power to the pressing plate. The first driving member 302 can drive the first pressing plate 303 to move toward or away from the inner edge of the window frame or door frame according to the detection requirements, ensuring that the sealing film 1 can be accurately pressed at different positions. The control flexibility of the driving member ensures that the equipment can adapt to different window frame shapes and improves the overall operational flexibility.

[0088] The first pressing plate 303 is directly connected to the first driving member 302, and the movement of the driving member is transmitted to the pressing plate by plugging. With this design, the pressing plate can move back and forth accurately according to the movement of the driving member, thereby pressing the horizontal or vertical inner edge of the window frame or door frame.

[0089] The first pressing plate 303 has a large surface area and can apply uniform pressing force to the inner edge of the window frame or door frame. Especially at the straight edge, the pressing plate can ensure that the edge of the sealing membrane 1 is fully pressed to reduce the risk of gas leakage.

[0090] In a specific embodiment, the first driving member 302 includes a first driving rod and an adjusting nut. The first driving rod has an external thread and is inserted into the first connecting member 301. By rotating the adjusting nut, the first driving rod is extended or retracted to change the length of the first connection.

[0091] The seventh embodiment of the present invention provides a door and window air tightness detection device, and based on the previous embodiment, the installation component 2 includes: A first mounting frame 203 and a second mounting frame 204; Wherein, the first mounting frame 203 is arranged along the length direction of the window frame or door frame; Wherein, the second mounting frame 204 is connected to the first mounting frame 203 and is arranged vertically with the first mounting frame 203; Furthermore, the sealing film 1 is pressed between the mounting assembly 2 and the door frame or window frame; Furthermore, the installation component 2 is placed inside the space enclosed by the inner edge of the door frame or window frame.

[0092] In this embodiment, the first mounting frame 203 and the second mounting frame 204 are rod-shaped structures. They are connected to form a rectangular frame structure. In addition, the sealing film 1 is pressed between the mounting assembly 2 and the door frame or window frame. That is, when the sealing film 1 expands due to gas delivery, the mounting assembly 2 can effectively limit its free expansion, ensuring that the sealing film 1 is always in a controlled state, and avoiding poor fitting or deformation of the sealing film 1 due to expansion.
