Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection devices, in particular to an airtightness detection device for building exterior windows adapted to different models. Background Art

[0002] In the process of the construction industry, the detection of the airtightness of windows is an indispensable step. By detecting the airtightness of windows, it can be judged whether the windows meet the use standards, so as to determine whether the windows are qualified products.

[0003] For example, Chinese Patent CN220322627U proposes a window sealing device for airtightness detection. There are multiple support plates. The outer side walls of the multiple support plates press the film for sealing the window against the inner side wall of the window lintel. A closed sealing cavity is formed between the film and the window; a fixed block, and multiple telescopic rods are arranged on the outer side wall of the fixed block. One ends of the multiple telescopic rods far away from the fixed block are hinged to the support plates; one end of the fixed block is hinged with a support column, and a support foot is fixedly arranged at the end of the support column far away from the fixed block, and the support foot presses against the ground. By using the support plates and the corresponding fixed block and telescopic rods, it can be quickly installed during use, improving the convenience of equipment carrying.

[0004] However, in the above patent, it is necessary to adjust the angle between the support column and the wall to prevent the support column from tipping to the side away from the window, and the operation steps are relatively cumbersome and need to be further simplified; in addition, the above patent cannot be adapted to windows of different heights.

At least one group of first cylinders is rotatably connected between the upper end and the lower end of the second support plate. A support rod is rotatably connected between the upper end of each first cylinder and the lower end of the second support plate. The rear end of the frame is fixedly connected with a hinge seat. The hinge seat is rotatably connected to the output end of the first cylinder.

[0016] Furthermore, the distance adjustment component includes a support block, a first connecting block, an electric slider, a guide rail and a second connecting block. The front end of the first support plate is fixedly connected with a second connecting block. The top of the second connecting block is fixedly connected with a guide rail.

[0017] Furthermore, a telescopic rod is connected between the first connecting block and the support block.

[0021] Furthermore, self-locking universal wheels are rotatably connected to the four corners of the bottom of the frame.

[0022] Furthermore, a push handle is fixedly connected to the rear end of the support frame.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] When the present utility model starts the second cylinder, the output end of the second cylinder drives the first support plate to move up and down under the limiting and guiding action of the second support plate through the connecting seat. The first support plate drives the detection component to move up and down through the distance adjustment component, so as to perform airtightness detection on windows of different heights; when it is necessary to perform airtightness detection on a window with an inclined angle, such as some attic skylights, at this time, the angle is adjusted through the angle adjustment component. The angle adjustment component drives the detection component to rotate through the second support plate and the distance adjustment component, so as to adapt to the airtightness detection requirements of windows at different angles; during detection, the distance adjustment component drives the detection component to move forward to contact the measurement point. After the detection is completed, the distance adjustment component drives the detection component to move backward to disengage from the measurement point. Therefore, only the distance between the detection component and the window needs to be adjusted through the distance adjustment component before and after measurement, without adjusting the angle between the support frame and the wall or the ground. The steps are simple and convenient to use. At the same time, the frame provides stable support for the support frame to prevent the support frame from tipping away from the window.

[0025] When the present utility model needs to perform airtightness detection on a window with an inclined angle, the first cylinder is started at this time. The output end of the first cylinder extends or contracts from the inside of the first cylinder. Since the upper end of the first cylinder is rotatably connected to the second support plate and the output end of the first cylinder is rotatably connected to the hinge seat, when the output end of the first cylinder extends or contracts, the upper end of the first cylinder drives the second support plate to rotate around the upper end of the support frame. The second support plate drives the detection component to deflect upward or downward through the distance adjustment component, so as to adapt to the airtightness detection requirements of windows at different angles.

[0026] When the present utility model is detecting, the electric slider moves forward under the limiting and guiding action of the guide rail. The electric slider drives the detection component to move forward to contact the measurement point through the first connecting block. After the detection is completed, the electric slider drives the detection component to move backward to disengage from the measurement point. Therefore, only the electric slider, the guide rail, and the first connecting block are needed to realize the contact or separation between the detection component and the window to be measured before and after measurement. The steps are simple and convenient to use; during the movement of the electric slider and the first connecting block, the telescopic rod plays a limiting role on the first connecting block, thus preventing the electric slider from slipping on the guide rail.

[0027] In the present utility model, when the electric slider drives the fourth connecting block to move forward through the first connecting block, the fourth connecting block drives the first test cavity, the second test cavity, the third test cavity and the fourth test cavity to move forward until they contact the measurement point. The first test cavity, the second test cavity, the third test cavity and the fourth test cavity respectively form a closed space with the window. At this time, an external vacuum pump evacuates the first test cavity, the second test cavity, the third test cavity and the fourth test cavity, and the air pressure sensors in the first test cavity, the second test cavity, the third test cavity and the fourth test cavity measure the airtightness according to the air pressure change.

[0038] Embodiment 1

[0039] In some embodiments, please refer to the accompanying drawings of the specification Figures 1-5 , a building exterior window airtightness detection device adapted to different models, including a frame 1;

[0040] The upper end of the frame 1 is fixedly connected with a support frame 4;

[0041] The rear end of the frame 1 is connected with an angle adjustment component 3 for adapting to windows in different directions;

[0042] The upper end of the angle adjustment component 3 is connected with a height adjustment component 5;

[0043] The front end of the height adjustment component 5 is connected with a distance adjustment component 6;

[0044] The front end of the distance adjustment component 6 is connected with a detection component 7 adapted to different models;

[0045] The height adjustment assembly 5 includes a second cylinder 51, a connecting seat 52, a first support plate 53 and a second support plate 54. The rear end of the second support plate 54 is rotatably connected to the upper end of the support frame 4. The lower end of the second support plate 54 is connected to the angle adjustment assembly 3. The upper end of the second support plate 54 is fixedly connected with a second cylinder 51. The output end of the second cylinder 51 is fixedly connected with a connecting seat 52. The connecting seat 52 is fixedly connected with the first support plate 53. The first support plate 53 is in limiting sliding connection with the second support plate 54. The front end of the first support plate 53 is connected to the distance adjustment assembly 6;

[0046] Start the second cylinder 51. The output end of the second cylinder 51 drives the first support plate 53 to move up and down under the limiting and guiding action of the second support plate 54 through the connecting seat 52. The first support plate 53 drives the detection assembly 7 to move up and down through the distance adjustment assembly 6, so as to perform airtightness detection on windows at different heights. When it is necessary to perform airtightness detection on a window with an inclined angle, such as some attic skylights, at this time, the angle is adjusted through the angle adjustment assembly 3. The angle adjustment assembly 3 drives the detection assembly 7 to rotate through the second support plate 54 and the distance adjustment assembly 6, so as to adapt to the airtightness detection requirements of windows at different angles. During detection, the distance adjustment assembly 6 drives the detection assembly 7 to move forward until it contacts the measurement point. After the detection is completed, the distance adjustment assembly 6 drives the detection assembly 7 to move backward until it disengages from the measurement point. Therefore, only the distance between the detection assembly 7 and the window needs to be adjusted through the distance adjustment assembly 6 before and after measurement, without adjusting the angle between the support frame 4 and the wall or the ground. The steps are simple and convenient to use. At the same time, the frame 1 provides stable support for the support frame 4 to prevent the support frame 4 from tipping away from the window;

[0047] The angle adjustment assembly 3 includes a hinge seat 31, a first cylinder 32, a connecting plate 33, a slider 34 and a support rod 35. The rear end of the support frame 4 is fixedly connected with a connecting plate 33. An arc-shaped groove is formed in the connecting plate 33. The slider 34 is in limiting sliding connection with the arc-shaped groove. The slider 34 is fixedly connected to the bottom of the second support plate 54. At least one group of first cylinders 32 is rotatably connected to the bottom of the second support plate 54. A support rod 35 is rotatably connected between the upper end of the first cylinder 32 and the lower end of the second support plate 54. The rear end of the frame 1 is fixedly connected with a hinge seat 31. The hinge seat 31 is rotatably connected to the output end of the first cylinder 32;

[0048] When airtightness detection is required for a window with an inclined angle, the first cylinder 32 is started at this time. The output end of the first cylinder 32 extends or retracts from inside the first cylinder 32. Since the upper end of the first cylinder 32 is rotatably connected to the second support plate 54 and the output end of the first cylinder 32 is rotatably connected to the hinge seat 31, when the output end of the first cylinder 32 extends or retracts, the upper end of the first cylinder 32 drives the second support plate 54 to rotate around the upper end of the support frame 4. The second support plate 54 drives the detection component 7 to deflect upward or downward through the distance adjustment component 6, so as to adapt to the airtightness detection requirements of windows at different angles;

[0049] The distance adjustment component 6 includes a support block 61, a first connection block 62, an electric slider 64, a guide rail 65 and a second connection block 66. A second connection block 66 is fixedly connected to the front end of the first support plate 53. The top of the second connection block 66 is fixedly connected to a guide rail 65. The guide rail 65 is in limit sliding connection with the electric slider 64. The upper end of the electric slider 64 is fixedly connected to a first connection block 62. The rear end of the second connection block 66 is fixedly connected to a support block 61. The front end of the first connection block 62 is connected to the detection component 7;

[0050] An expansion link 63 is connected between the first connection block 62 and the support block 61;

[0051] The expansion link 63 is divided into a telescopic slide rod and a telescopic sleeve. The telescopic slide rod and the telescopic sleeve are in limit sliding connection. The telescopic sleeve is fixedly connected to the first connection block 62, and the telescopic slide rod is fixedly connected to the support block 61;

[0052] When detecting, the electric slider 64 moves forward under the limit guiding action of the guide rail 65. The electric slider 64 drives the detection component 7 to move forward to contact the measurement point through the first connection block 62. After the detection is completed, the electric slider 64 drives the detection component 7 to move backward to disengage from the measurement point. Therefore, only through the electric slider 64, the guide rail 65 and the first connection block 62 can the contact or separation between the detection component 7 and the window to be measured be realized before and after measurement. The steps are simple and easy to use; during the movement of the electric slider 64 and the first connection block 62, the expansion link 63 plays a limiting role on the first connection block 62, thus preventing the electric slider 64 from slipping off the guide rail 65;

[0053] The detection component 7 includes a test chamber and a fourth connection block 75. The front end of the first connection block 62 is fixedly connected to a fourth connection block 75.

When folded, they can fit windows of smaller models, and when unfolded, they can fit windows of larger models. When not in use, the first test chamber 71, the second test chamber 72, the third test chamber 73, and the fourth test chamber 74 can be folded to the minimum, saving space and facilitating storage.

[0055] Preferably, air pressure sensors are fixedly connected inside the first test chamber 71, the second test chamber 72, the third test chamber 73, and the fourth test chamber 74.

[0056] Preferably, self-locking universal wheels 2 are rotatably connected to the four corners of the bottom of the frame 1.

[0057] Preferably, a push handle 8 is fixedly connected to the rear end of the support frame 4.

[0058] When the electric slider 64 drives the fourth connecting block 75 forward through the first connecting block 62, the fourth connecting block 75 drives the first test chamber 71, the second test chamber 72, the third test chamber 73, and the fourth test chamber 74 forward to contact the measurement point. The first test chamber 71, the second test chamber 72, the third test chamber 73, and the fourth test chamber 74 respectively form a closed space with the window. At this time, an external vacuum pump evacuates the inside of the first test chamber 71, the second test chamber 72, the third test chamber 73, and the fourth test chamber 74, and the air pressure sensors inside the first test chamber 71, the second test chamber 72, the third test chamber 73, and the fourth test chamber 74 measure the airtightness according to the air pressure change.
