Description

Technical Field

[0001] This utility model relates to the field of building engineering testing technology, and in particular to a building engineering airtightness testing device. Background Technology

[0002] In modern construction engineering, testing the airtightness of building envelopes (such as walls, door and window joints, and pipe penetrations) is an important step in ensuring building energy consumption, sound insulation, and safety.

[0003] Currently, performing such fixed-point airtightness testing typically requires a testing equipment set, which mainly includes a fan for applying pressure, a sealing cover for covering the testing area, and a host for control and data display.

[0004] However, existing testing devices generally suffer from low integration in their structural design. The fan, main unit, sealing cover, and other auxiliary measuring tools are often separate components. This forces testing personnel to carry multiple equipment boxes or loose parts to the site, making transportation and relocation extremely inconvenient, and also increasing the risk of auxiliary tools being lost or damaged in the chaotic construction site.

[0005] Furthermore, during on-site assembly and deployment, the existing equipment revealed its cumbersome operation. In particular, when aligning the fan with testing points at different heights (such as high window corners or low ground levels), operators often had to manually lift and adjust it, or rely on temporary supports, lacking a stable and convenient height adjustment mechanism. This non-integrated design significantly reduced the efficiency of testing preparation and hindered rapid storage after testing.

[0006] Therefore, this utility model proposes an airtightness testing device for building engineering to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the air tightness testing devices for building engineering, such as dispersed structure, low integration, difficulty in integrated storage, easy loss of auxiliary tools, and cumbersome and laborious on-site assembly and testing height adjustment process, this utility model aims to provide a building engineering air tightness testing device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a building engineering air tightness testing device, including: a support box, in which a main unit display block is fixedly fixed, and an opening cover is rotatably connected to the top of the support box, the opening cover and the support box being detachably locked by a buckle; and a fan, with a sealing component fixed at the air inlet of the fan.

[0009] The device also includes a storage mechanism fixed to the inner surface of the open cover; Furthermore, the device also includes a quick-connect mechanism for detachably connecting the fan to the support box.

[0010] The quick-connect mechanism includes support plate b, electric telescopic rod, follower column and support plate a.

[0011] In terms of assembly, support plate b is fixed to the outside of support box, the bottom ends of electric telescopic rod and follower column are vertically fixed to the top surface of support plate b, support plate a is fixed to the top of electric telescopic rod and follower column, and the fan is supported and fixed on support plate a. This structure realizes the integration and lifting of fan and support box.

[0012] Preferably, the storage mechanism includes an adjustment plate fixed to the inner surface of the open cover, and the adjustment plate has multiple adjustment slots for subsequent snap-fit ​​positioning.

[0013] Furthermore, as a specific implementation of the aforementioned storage mechanism, the storage mechanism also includes an elastic plate, a fixed post, and a rubber ball. The fixed post is fixedly connected to both ends of the elastic plate, and a rubber ball is fixed to the end of each fixed post. The rubber ball can be elastically engaged in any adjustment slot on the adjustment plate, and the clamping position is adjusted by the cooperation between the rubber ball and the adjustment slot.

[0014] Preferably, the quick-connect mechanism further includes connecting wire a, connecting wire b, and a threaded connecting ring. Connecting wire a and connecting wire b are used to achieve electrical connection between the fan and the main display block, while the threaded connecting ring is used to quickly connect and fix the mating ends of connecting wire a and connecting wire b, ensuring the reliability of signal transmission.

[0015] Preferably, the sealing assembly includes a conical shroud and a sensor fixed inside the conical shroud for collecting airtightness data.

[0016] Furthermore, as an improvement to the aforementioned sealing assembly, the sealing assembly also includes a sealing rubber gasket and a sealing membrane. The sealing rubber gasket is fixed to the edge of the large opening of the conical shroud for contact with the surface to be tested, while the sealing membrane covers the port of the conical shroud.

[0017] More preferably, in order to enhance the sealing effect, the sealing rubber gasket has multiple protrusions on its working surface facing the surface to be tested. These protrusions can increase friction and adapt to uneven surfaces.

[0018] Preferably, the sensor fixed inside the conical cover is electrically connected to the host display block so as to transmit the collected data to the host display block for processing and display.

[0019] Preferably, a T-shaped partition is fixed in the inner cavity of the support box. The T-shaped partition is used to neatly divide the internal space of the support box, which facilitates the storage of cables or other accessories.

[0020] This utility model has the following beneficial effects: 1. This utility model, by setting up a support box and cooperating with a quick-connect mechanism that allows for the rapid disassembly of the fan, enables the main components such as the fan to be stored inside the support box. This solves the problems of existing detection devices being structurally dispersed, difficult to integrate and store, and prone to component loss, achieving the technical effect of high device integration, compact structure, and easy portability and storage.

[0021] 2. This utility model solves the problem of where there is nowhere to store light tools or where they are stored in a mess, and the inability to accommodate tools of different sizes in the prior art by setting a storage mechanism inside the open cover. The storage mechanism uses the cooperation of elastic plate, rubber ball and adjustment groove to adjust the clamping width, thus achieving the technical effect of flexible storage and improving the utilization rate of box space.

[0022] 3. This utility model solves the problem of the existing technology where the fan is highly dependent on manual adjustment and the deployment is cumbersome and laborious by setting an electric telescopic rod and a follow-up column in the quick connection mechanism to support the fan, and achieves the technical effects of rapid deployment, automated height adjustment and improved on-site testing efficiency.

[0023] 4. This utility model solves the problems of poor adhesion between the sealing cover and the surface to be tested, insufficient friction, and easy leakage during testing by setting multiple protrusions on the sealing rubber gasket of the sealing component, thereby achieving the technical effect of enhancing friction and improving sealing stability.

Figure 1 The quick-connect mechanism 5 includes a support plate b55, an electric telescopic rod 56, a follower column 57, and a support plate a54. The support plate b55 is fixed to the outside of the support box 1. The bottom ends of the electric telescopic rod 56 and the follower column 57 are vertically fixed to the top surface of the support plate b55. The support plate a54 is fixed to the top of the electric telescopic rod 56 and the follower column 57. The fan 6 is supported and fixed on the support plate a54. The quick-connect mechanism 5 also includes a connecting wire a51, a connecting wire b52, and a threaded connecting ring 53. The connecting wire a51 and the connecting wire b52 are used to electrically connect the fan 6 and the main display block 7. The threaded connecting ring 53 is used to quickly connect and fix the mating ends of the connecting wire a51 and the connecting wire b52.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The storage mechanism 4 includes an adjustment plate 44 fixed to the inner surface of the open cover 2, and the adjustment plate 44 has multiple adjustment slots 45.

[0032] The storage mechanism 4 also includes an elastic plate 41, a fixed column 42 and a rubber ball 43. The two ends of the elastic plate 41 are fixedly connected to the fixed column 42, and the end of the fixed column 42 is fixed with a rubber ball 43. The rubber ball 43 has corresponding friction and can be elastically engaged in any adjustment groove 45.

[0033] When the position of the elastic plate 41 needs to be adjusted to fit tools of different sizes, the rubber ball 43 is disengaged from the current adjustment groove 45 by pulling the fixed column 42 and moves into the interior of another adjustment groove 45, thereby adjusting the different clamping widths.

[0034] In a preferred embodiment, in order to achieve quick assembly and disassembly and signal connection between the fan 6 and the main display block 7, the quick connection mechanism 5 further includes a connecting wire a51, a connecting wire b52 and a threaded connecting ring 53. The connecting wire a51 and the connecting wire b52 are used to electrically connect the fan 6 and the main display block 7, and the threaded connecting ring 53 is used to quickly connect and fix the mating ends of the connecting wire a51 and the connecting wire b52.

[0035] As another preferred embodiment, please refer to Figure 1 and Figure 5 The sealing assembly 47 is described in detail. The sealing assembly 47 includes a conical cover 473 and a sensor 48 fixed inside the conical cover 473.

[0036] Preferably, in order to achieve a reliable seal, the sealing assembly 47 further includes a sealing rubber gasket 471 and a sealing membrane 472, wherein the sealing rubber gasket 471 is fixed to the edge of the large opening of the conical cover 473, and the sealing membrane 472 covers the port of the conical cover 473.

[0037] Furthermore, in order to increase the friction with the test surface and the sealing stability, the sealing rubber gasket 471 has multiple protrusions on its working surface facing the test surface.

[0038] Preferably, in order to transmit the detection data to the host, the sensor 48 is electrically connected to the host display block 7.

[0039] As another preferred embodiment, in order to facilitate the partitioning and storage of the fan 6 and other components inside the support box 1, a T-shaped partition plate 46 is fixed in the inner cavity of the support box 1.

[0040] The working principle is as follows: When in use, first unlock the latch 3 to open the top cover 2 of the support box 1. The storage mechanism 4 inside the cover 2 is used to store light tools. When the storage width needs to be adjusted, pull the fixing post 42 of the storage mechanism 4 so that the rubber ball 43 connected to the fixing post 42 is disengaged from the current adjustment slot 45 with the elastic assistance of the elastic plate 41, moves into and locks into another adjustment slot 45 to clamp tools of different sizes.

[0041] During deployment, the fan 6 is fixed to the top of the electric telescopic rod 56 and the follower column 57 via the support plate a54, while the bottom of the electric telescopic rod 56 and the follower column 57 are fixed to the outside of the support box 1 via the support plate b55. The operator quickly connects the connecting wire a51 and the connecting wire b52 via the threaded connecting ring 53, realizing electrical communication between the fan 6 and the sensor 48 and the main display block 7 inside the support box 1. Subsequently, the electric telescopic rod 56 is activated to extend it, thereby driving the support plate a54, the fan 6, and the follower column 57 to rise synchronously to the required detection height. The follower column 57 provides stable auxiliary support during this process.

[0042] During testing, the sealing assembly 47 on the fan 6 is pushed towards the surface to be tested. The conical cover 473 in the sealing assembly 47 covers the testing area. The sealing rubber gasket 471 at the large opening of the conical cover 473 and its multiple protrusions are in close contact with the surface to be tested, while the sealing membrane 472 assists in sealing. The fan 6 is started, and the sensor 48 fixed inside the conical cover 473 begins to sense the airtightness data and transmits the signal to the main display block 7 for display via the connecting line.

[0043] After testing, retract the electric telescopic rod 56 to lower the fan 6 to its storage height. Disconnect the threaded connecting ring 53 and store cables and other accessories in the inner cavity of the support box 1. The T-shaped partition 46 can be used to separate the accessories. Close the opening cover 2 and lock it with the buckle 3 for easy carrying. Through the synergistic action of the storage mechanism 4 and the quick-connect mechanism 5, the problems of difficult storage and cumbersome on-site deployment and adjustment of the testing device in the prior art are solved.
