Background
The air tightness of the protective door and window in the civil air defense engineering construction is related to the life safety of the temporary personnel in war, and the protective door and window has high air tightness requirement. In the residential building industry, the air tightness of doors and windows is critical to ensure energy efficiency and indoor environmental comfort. Poor air tightness may lead to energy waste, increase heating and cooling costs, and may affect indoor air quality. Therefore, it is an important task to accurately detect and evaluate the airtightness of doors and windows. More seriously, when the air tightness of the door and the window does not meet the related standard, serious potential safety hazard exists in the case of fire.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 9, the following embodiments of the present invention are provided:
as shown in fig. 1, a first embodiment of the present invention provides a nondestructive airtight detection apparatus for doors and windows, including:
A support assembly 1 having a lateral load end 101 and a longitudinal load end 102;
A first lamination assembly 2 having a first connection end 201 and a first lamination end 202;
a second lamination assembly 3 having a second connection end 301 and a second lamination end 302;
a sealing film 4;
a gas delivery port 5, which is arranged on the sealing film 4 and is used for connecting a gas delivery system;
wherein the first connection end 201 is connected to the lateral load end 101 and the longitudinal load end 102;
wherein the second connection end 301 is connected to the first lamination assembly 2;
Wherein the first pressing end 202 presses the edge of the sealing film 4 to the inner horizontal wall surface and the vertical wall surface of the door frame or the window frame;
wherein the second pressing end 302 presses the edge of the sealing film 4 to the inner corner wall surface of the door frame or the window frame;
and, the support component 1 is positioned in the space M formed by the door frame or the window frame.
In this embodiment, when door and window air tightness detection is performed, especially when a differential pressure detection mode is used, in order to ensure that the sealing film 4 is tightly pressed on the wall body of the door frame or the window frame, a pressing frame (which means that the sealing film 4 is pressed on the frame on the wall body) is usually assembled on the wall surface by using screws, and this destructive mode makes the wall body still need to be repaired after the detection is completed.
The pressing frame of the airtight detecting device is usually located outside the door frame or the window frame (not inside the space M defined in the present embodiment). When space is very limited, it is difficult to assemble the lamination frame with a larger size at a correct position, so that the air tightness detection of the door and the window cannot be realized.
Based on this, the present embodiment is expected to provide a nondestructive airtight detection apparatus that can not damage a wall or a door or window under a space-limited condition.
Thereby, the support assembly 1 may be disposed inside the space M. That is, the support assembly 1 does not occupy a space other than the door frame or the window frame, thereby achieving support for airtight detection of the door and window system in a small space.
On the basis of the above, the first lamination assembly 2 is provided on the lateral load end 101 face and the longitudinal load end 102 face of the support assembly 1 in view of not performing destructive installation. The lateral load end 101 surface means an end surface of the support member 1 in the width direction thereof, and the longitudinal load end 102 surface means an end surface of the support member 1 in the length direction thereof. The first laminating end 202 of the first laminating assembly 2 is used for laminating the sealing film 4 on a wall surface of a door frame or a window frame which is horizontal or vertical. Specifically, the first pressing end 202 applies a force to the edge of the sealing film 4 toward the wall surface so that the sealing film 4 closely fits on the wall surface.
Further, it is considered that the door frame or the window frame has corner wall surfaces, i.e., wall surfaces at 90 °. If the problem of the sealing film 4 is not tightly covered at the edge of the sealing film, the gas is easy to escape. Thereby, a second lamination assembly 3 is added, and the second lamination assembly 3 is used for exerting a force on the edge of the sealing film 4 at the position so as to enable the edge to be tightly attached to the corner wall surface.
As shown in fig. 1 to 2, in a specific embodiment, the support assembly 1 comprises a number of horizontal bars arranged horizontally and a number of vertical bars arranged vertically. The horizontal bars and the vertical bars form a rectangular frame structure.
As shown in fig. 3, in a specific embodiment, the first lamination assembly 2 includes a first hinge, i.e., a first connection end 201, and the first hinges of the plurality of first lamination assemblies 2 are respectively hinged to the lateral load end 101 and the longitudinal load end 102. The first pressure-covering assembly 2 further comprises a first sleeve 203 and a first pressure-covering rod 204, the first sleeve 203 is in threaded connection with the first pressure-covering rod 204, and a first pressure-covering plate 205 with a straight plate structure, namely a first pressure-covering end 202, is connected to the end part of the first pressure-covering rod 204. By rotating the first sleeve 203, the first pressing rod 204 is driven to rotate out or back, so as to push or pull the first pressing plate 205 to press or not press the edge of the sealing film 4 on the wall surface.
In one embodiment, as shown in fig. 4, the second lamination assembly 3 has the same structure as the first lamination assembly 2, except that the second lamination plate 305 has a right angle structure to conform to the shape of the corner wall surface. And, the second connection end 301 is connected to the first lamination component 2. The reason is that in this form, the second pressing component 3, that is, the second pressing plate 305 with a right-angle structure, can apply a relatively larger pressing force to the horizontal wall surface or the vertical wall surface by adjusting the installation angle of the second connecting end 301 on the first pressing component 2, so that the edge of the sealing film 4 has relatively better sealing performance on one of the horizontal wall surface or the vertical wall surface.
As shown in fig. 1 to 4, in a specific embodiment, the nondestructive airtight detection of the door and window is performed by installing the support assembly 1, the first lamination assembly 2 and the second lamination assembly 3. The device is placed in a door frame or a window frame to be tested, and the first covering component 2 and the second covering component 3 are adjusted to enable the edges of the sealing film 4 to be pressed to the wall surface. The gas transmission system is connected with the gas transmission port 5 and comprises a gas inlet device 6 and a detection device 7; the air inlet device 6 and the detection device 7 are communicated with the air delivery port 5; wherein the gas inlet device 6 is configured to deliver gas into a detection space formed by the sealing film 4 and the door body or the window body; wherein the detection means 7 are configured to detect the gas pressure in the detection space. The air inlet device 6, such as an air pump, delivers air into the detection space, and the detection device 7, such as an air pressure detector, detects the air pressure in the detection space, stops air inlet and maintains the pressure for a period of time after the air pressure in the detection space reaches a set pressure, and monitors the change of the air pressure in the detection space within the time range. If the gas pressure drop rate is significantly lower than the set value, the gas tightness of the door or window to be tested is poor, otherwise, the gas tightness is good.
In summary, the door and window nondestructive airtight detection apparatus provided in this embodiment includes at least:
One of the most significant benefits of the present invention is its non-destructive mounting characteristics. The traditional air tightness detection method often needs to install a fixing device such as a screw on a wall body, and repair work is needed after detection is completed, so that extra maintenance cost is increased, and the attractive appearance and structural integrity of a building can be influenced. In contrast, the present embodiment avoids any damage to the wall by incorporating the support assembly 1 and two types of the lamination assembly designs, and achieves the integrity and aesthetic maintenance during the inspection process.
In urban environments and modern buildings, where space is often limited, it is difficult for conventional large detection devices to accommodate such environments. The invention has compact design, and all components can be arranged in the inner space M of the door and window frame, thereby greatly facilitating the installation and operation in the environment with limited space without occupying extra space outside or inside.
The design of the device ensures that the sealing film 4 can be more tightly and evenly fitted to all edges of the door or window frame, including inside corner walls that are difficult to handle. By optimizing the sealing effect, the change of the gas pressure can be measured and analyzed more accurately, so that the detection efficiency and accuracy are improved, the gas leakage is effectively prevented, and the reliability of the detection result is ensured.
The user can save the cost of repair and refinishing because no changes are required to the inspection environment. In addition, the design of the device allows for quick installation and removal, reduces labor and time costs, and is particularly suitable for commercial buildings and houses that require frequent inspection, with significant maintenance costs in the long run.
The nondestructive airtight detection device is not only suitable for newly built buildings, but also suitable for maintenance work of historical buildings, and particularly provides an efficient and economical solution for building protection under the condition that the appearance or the structure of the building is not allowed to be changed.
The second embodiment of the invention provides a door and window nondestructive airtight detection device, and on the basis of the first embodiment, the first covering component 2 has a stroke L1;
the second lamination assembly 3 has a stroke L2;
The stroke L1 and the stroke L2 are adjustable;
Wherein L2> L1.
In this embodiment, the stroke adjusting function of the first and second cover members 2 and 3 allows the user to precisely adjust the pressing position and force of each cover end according to the specific size and shape of the door and window frame. The stroke adjustability is particularly suitable for dealing with doors and windows of various different standard or nonstandard sizes, so that the air density detection device has wider applicability and flexibility.
When carrying out door and window gas tightness and examining, especially in diversified building environment, can optimize through adjustment L1 and L2 and cover pressure dynamics and position, guarantee that sealing membrane 4 can laminate more perfect on the door and window seam of different width and angle. Such a design significantly improves the accuracy and reliability of the detection while reducing the problem of damage or insufficient air tightness of the sealing film 4 caused by improper lamination.
In summary, this embodiment not only inherits all the advantages of the first embodiment, such as non-destructive installation and the characteristics suitable for space-limited environments, but also increases the adaptability of the device by introducing adjustable strokes L1 and L2, so that it can better serve various complex and variable application scenarios, and further improves the practicality and market competitiveness of the product.
In a specific embodiment, the stroke L1 of the first lamination assembly 2 and the stroke L2 of the second lamination assembly 3 are realized by respective sleeves. The corresponding screwing-in or screwing-out amount of the pressure-covering rod is adjusted by rotating the sleeve, so that the adjustment of the strokes L1 and L2 is realized.
The third embodiment of the present invention provides a door and window nondestructive airtight detection apparatus, and on the basis of the previous embodiment, the stroke L1 includes a sub-stroke L11 and a sub-stroke L12;
the adjusting precision of the sub-stroke L11 is n11, and the adjusting precision of the sub-stroke L12 is n12;
and n11> n12;
the stroke L2 comprises a sub-stroke L21 and a sub-stroke L22;
The adjustment precision of the sub-stroke L21 is n21, and the adjustment precision of the sub-stroke L22 is n22;
And n21> n22;
Wherein the directions of the sub-stroke L11 and the sub-stroke L12 are opposite;
wherein, the direction of the sub-stroke L21 is opposite to that of the sub-stroke L22.
In this embodiment, it is further found that there is a mechanism of unidirectional regulation in the prior art, but that there is such a mechanism:
The unidirectional adjustment of the fixed precision cannot be adapted to the diversity and complexity of the door and window structure. When doors and windows with different thicknesses or irregular shapes are processed, a single adjusting step length may be too large or too small, and an ideal sealing effect cannot be achieved. Moreover, when the overlay position needs to be very precisely adjusted to achieve a perfect seal, the fixed amount of adjustment may result in a failure to fine tune, requiring multiple iterative adjustments to approach the ideal state, which is time consuming and inefficient.
Therefore, in the practical operation of door and window airtight detection, the limitation of unidirectional fixed precision adjustment may cause the following technical problems:
for doors and windows with different thickness or multiple frames, a fixed amount of adjustment may not achieve uniform pressure at all points of contact, thereby resulting in incomplete sealing, affecting the accuracy and reliability of the detection. In an attempt to achieve the desired sealing condition, the operator may need to adjust repeatedly a number of times, resulting in overall inefficiency.
Based on this, the bidirectional adjustment mechanism provided in this embodiment, and the forms of different adjustment accuracy, can combine coarse adjustment (i.e., adjustment accuracy corresponding to the sub-stroke L12 and the sub-stroke L22) and fine adjustment (i.e., adjustment accuracy corresponding to the sub-stroke L11 and the sub-stroke L21) to allow the operator to quickly approach the ideal press-fit position, and then perform fine adjustment to achieve the optimal sealing effect. This not only improves the accuracy of the adjustment, but also optimizes the efficiency of the adjustment process. And different adjusting precision can be better adapted to different types of door and window structures, and especially for complex or abnormal door and window frames, good sealing can be ensured to be realized at all necessary contact points. In addition, by reducing the required adjustment times and improving the adjustment accuracy, the overall quality and speed of detection can be remarkably improved, and the operation complexity and the potential error rate can be reduced.
In one embodiment, as shown in fig. 3, the first pressing rod 204 of the first pressing assembly 2 is divided into two sections and connected to two ends of the first sleeve 203 through two adjusting nuts, respectively. One of the segments has a pitch smaller than the pitch of the other segment in the form of an adjustment accuracy n11 constituting the sub-stroke L11 that is greater than the adjustment accuracy n12 of the sub-stroke L12.
In one embodiment, as shown in fig. 4, the second pressing rod 304 of the second pressing assembly 3 is divided into two ends, and is connected to two ends of the second sleeve 303 through two adjusting nuts, respectively. One of the segments has a pitch smaller than the pitch of the other segment in the form of an adjustment accuracy n21 constituting the sub-stroke L21 that is greater than the adjustment accuracy n22 of the sub-stroke L22.
The larger pitch design allows the operator to quickly cover a larger adjustment range, which is useful when initially setting up the device or accommodating large dimensional variations, and the smaller pitch design allows the operator to make minor adjustments, which are critical to ensuring sealing effect, especially when dealing with small or sensitive door and window joints.
As shown in fig. 1 and fig. 4, a fourth embodiment of the present invention provides a nondestructive airtight detection apparatus for doors and windows, and on the basis of the previous embodiment, an included angle a1 is formed between an axis of the second connecting end 301 and an axis of the first pressing component 2 connected with the second connecting end;
the axis of the second pressing end 302 has an included angle a2 with the horizontal wall surface or the vertical wall surface;
The included angle a1 and the included angle a2 are adjustable;
and, the end face of the transverse load end 101 or the longitudinal load end 102 connected with the axis of the first connection end 201 has an included angle b1;
an included angle b2 is formed between the axis of the first pressing end 202 and the horizontal wall surface or the vertical wall surface;
And the included angle b1 and the included angle b2 are adjustable.
In this embodiment, by adjusting the included angles a1, a2, b1 and b2, the detection device can adapt to various installation conditions and specific requirements of the door and window frame, especially in installation scenes with complex angles or non-conventional installation scenes. The adjustable included angle enables the covering and pressing assembly to be better contacted with the door and window frame and the wall surface, and even and tight sealing can be achieved on the plane or the angled surface, so that the accuracy of air tightness detection is improved. An operator can adjust the included angle according to specific installation environment and detection requirements, and the use flexibility and detection efficiency of the device are improved.
In one embodiment, the second connection end 301 is a second hinge, which is hinged to the first pressure-covering rod 204 of the first pressure-covering assembly 2, and the second pressure-covering end 302 is formed by a second pressure-covering plate 305 hinged to the second pressure-covering rod 304. The first connection end 201 is a first hinge member hinged to the lateral load end 101 and the longitudinal load end 102, and the first pressure-applying end 202 is formed by a first pressure-applying plate 205 hinged to the first pressure-applying rod 204.
As shown in fig. 7 to 9, a fifth embodiment of the present invention provides a nondestructive airtight detection apparatus for doors and windows, and based on the previous embodiment, the second pressing component 3 has a second driving member 306;
wherein the second driving member 306 is connected to the second pressing end 302;
wherein the second driving member 306 rotates in a first direction to have a driving state;
and, the second driving member 306 rotates in a second direction to have an unlocked state;
and, the driving state is configured to drive the second pressing end 302 to complete the adjustment of the stroke L2;
the unlock state is configured to release the drive state to the second crimp 302;
wherein the first direction and the second direction are the circumferential direction of the second lamination assembly 3, and the directions are opposite to each other.
In this embodiment, it has further been found that, because the second crimp assembly 3 is located near the edge of the window or door frame, when the second sleeve 303 is caused to rotate, the wrench will interfere with the edge of the door or window frame, so that the operator can only remove the wrench at a time and then reinstall and rotate the second sleeve 303 a small amount.
Based on this, the second driver 306 is added. When the second sleeve 303 needs to be rotated, the second cover rod 304 is driven to be screwed in or out by driving the second driving member 306 in the first direction to drive the second sleeve 303 to rotate (i.e., the driving state). When the wrench interferes with the door frame or the window frame, the operator does not need to detach the wrench, only needs to rotate along the second direction, and at this time, the second driving member 306 does not drive the second sleeve 303 to rotate (i.e. the unlocking state), so that the wrench can continue to rotate along the first direction at a position where the wrench does not interfere with the door frame or the window frame. The problem of space limitations that are often encountered during operation of a non-destructive airtight door and window inspection device, particularly when the equipment is adjusted in a small space, is thereby solved by adding the second drive member 306. This improvement significantly improves the user-friendliness and operating efficiency of the device.
In one embodiment, the second driver 306 and the second sleeve 303 form a ratchet arrangement. And, the second driving member 306 is a polygonal nut adapted to a wrench.
As shown in fig. 7 to 9, a sixth embodiment of the present invention proposes a nondestructive airtight inspection apparatus for doors and windows, and the second lamination assembly 3 has a conversion member 307 based on the previous embodiment;
wherein the switching member 307 is configured to switch the direction of the driving state to a second direction;
And switching the direction of the unlocking state to a first direction.
In the present embodiment, it was further found that the stroke L1 of the first lamination assembly 2 and the stroke L2 of the second lamination assembly 3 need to be reduced (to facilitate the removal of the device) in addition to being increased.
Based on this, it is necessary to ensure that, when the stroke increases, it can be achieved by the driving state in the first direction and the unlocking state in the second direction. When the required stroke reduction is ensured, the driving state in the second direction and the unlocking state in the first direction can be realized. The switching member 307 added in the present embodiment is used to switch the directions of the driving state and the unlocking state, so as to realize the function of increasing or decreasing the stroke.
As shown in fig. 7 to 9, in a specific embodiment, the second driver 306 has two pawls (the circumferential wall surface of the second sleeve 303 is provided with a ratchet engaged), and the two pawls are disposed opposite to each other, and the two pawls are abutted to the ratchet by one spring. The switch 307 is a switch lever connected to the second driving member 306, and one of the pawls engages the ratchet by pulling the switch lever, to form a driving state in the first direction, or vice versa.

the first driving piece is connected with the first connecting end 201 and the first covering end 202;
Wherein the first driver is configured to rotate in a third direction to increase the value of the travel L1;
wherein the first driver is configured to rotate in a fourth direction to decrease the magnitude of the stroke L1;
And, the third direction and the fourth direction are the circumferential direction of the first lamination component 2, and the directions are opposite to each other.
In this embodiment, the first driving member is the first sleeve 203. The first sleeve 203 has two threads in opposite directions inside and is screwed with a first blanket compression bar 204 divided into two. Thus, the first sleeve 203 is rotated in the third direction, so that the two first pressing rods 204 are screwed out to increase the stroke L1. Or the first sleeve 203 is rotated in the fourth direction so that the two first pressing bars 204 are screwed in to reduce the stroke L1.
In another embodiment, the first driving member is the two adjusting nuts described above. By rotating the adjustment nut in the third direction, the two sections of the first cover strut 204 are urged to unscrew to increase the travel L1. Or the adjusting nut is turned in the fourth direction so that the two first pressing bars 204 are screwed in to reduce the stroke L1.
