Description

Technical Field

[0001] This utility model belongs to the field of building energy conservation testing technology, specifically a mounting bracket for a building energy conservation testing heat flow meter. Background Technology

[0002] The building energy efficiency test heat flow meter is a key device for evaluating the energy efficiency performance of buildings. Based on Fourier's law of heat conduction, it accurately measures the heat flow and temperature changes of the building envelope (such as walls, doors, windows, roofs, etc.) through a heat flow probe and temperature sensor, and then calculates parameters such as the heat transfer coefficient to determine whether the thermal insulation performance meets the standards. Whether it is the energy efficiency acceptance of new buildings or the energy efficiency diagnosis and renovation of existing buildings, the heat flow meter can provide reliable data support.

[0003] In actual testing scenarios, staff commonly use tape to directly attach heat flow probes and temperature sensors to the wall. While this temporary fixing method seems convenient, it actually presents several hidden dangers. First, the adhesiveness of the tape decreases over time and with changes in ambient temperature and humidity. In high-temperature environments, the tape easily softens and loses its stickiness, causing the heat flow probe to detach. In humid environments, the tape's adhesiveness is further reduced by moisture intrusion, again failing to guarantee stable fixation of the heat flow probe. Second, it is difficult to ensure a tight fit between the heat flow probe and the wall during tape application; tiny air gaps can hinder heat flow transfer, affecting measurement accuracy. Furthermore, when the tape is removed after testing, adhesive residue can contaminate the wall surface and may even damage the wall coating, detracting from the building's appearance and increasing subsequent cleaning and repair costs.

[0004] Therefore, a mounting bracket for a building energy efficiency heat flow meter is proposed to address the above issues. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a mounting bracket for a building energy-saving heat flow meter, which has the advantages of achieving stable installation, precise fit, no damage to the wall surface, and convenient operation through the collaboration of a powerful suction cup and multiple components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building energy-saving heat flow meter mounting bracket, comprising a square frame, with powerful suction cups installed at the four corners of the front side of the square frame, a vertically arranged vertical rod at the center of the inner side of the square frame, a displacement driving assembly connected to the front side of the vertical rod, a bonding pressure plate connected to the left and right sides of the displacement driving assembly, a pressure bonding assembly connected to the rear side of the bonding pressure plate, and a positioning telescopic assembly provided above the pressure bonding assembly, the positioning telescopic assembly being located at the top of the bonding pressure plate.

[0008] Preferably, the displacement plate is provided with a threaded hole and a guide slide hole, the threaded hole is threadedly connected to a threaded rod, and the guide slide rod passes through the guide slide hole.

[0009] Preferably, the pressure bonding assembly includes a plurality of equidistantly arranged extension columns fixedly connected to the bonding pressure plate, a fixing plate fixedly connected to the end of each extension column, and a plurality of evenly distributed flexible protrusions provided on the side of the fixing plate away from the extension columns.

[0010] Preferably, the positioning telescopic assembly includes two symmetrical fixed ears fixed to the top of the fitting pressure plate, a movable rod passing through the fixed ears, a movable plate connected to one end of the movable rod near the square frame, a plurality of equally spaced slots on the side of the movable plate away from the movable rod, and a return spring connected between the movable plate and the fixed ears, the return spring being sleeved on the movable rod.

[0011] Preferably, the fixed ear has a positioning sliding hole that matches the movable rod, and the movable rod passes through the positioning sliding hole.

[0012] Preferably, a limiting block is threaded to the end of the movable rod away from the movable plate, and the diameter of the limiting block is larger than the diameter of the positioning sliding hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1.

[0015] 2. The displacement drive assembly of this utility model can precisely adjust the position of the bonding pressure plate through the cooperation of the threaded rod and the guide slide rod, which drives the fixed plate of the pressure bonding assembly and the flexible protrusion to squeeze the heat flow probe, so that it fits tightly against the wall surface, eliminates air gaps, and avoids heat transfer interference. Compared with the difficult-to-control fit of tape, it greatly improves the accuracy of measurement data. The design of the flexible protrusion can also adapt to heat flow probes of different shapes, enhancing compatibility. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5As shown, this utility model provides a mounting bracket for a building energy-saving heat flow meter, including a square frame 1. Powerful suction cups 2 are installed at the four corners of the front side of the square frame 1. A vertically arranged vertical rod 3 is located in the middle of the inner side of the square frame 1. A displacement driving component 4 is connected to the front of the vertical rod 3. Adhesive plates 5 are connected to the left and right sides of the displacement driving component 4. A pressure-applying adhesive component 6 is connected to the rear side of the adhesive plate 5. A positioning telescopic component 7 is located above the pressure-applying adhesive component 6 and is positioned on top of the adhesive plate 5. Compared to tape fixing, the powerful suction cups 2 at the four corners of the square frame 1 provide stronger adhesion to rough and uneven wall surfaces, avoiding the risk of detachment due to wall surface limitations. Unlike tape residue that contaminates the wall surface and damages the coating, this mounting bracket uses physical adsorption and mechanical fixing. The installation and disassembly processes do not damage the building surface, reducing subsequent cleaning and repair costs.

[0028] Specifically, the displacement drive assembly 4 includes a connecting bearing 41 installed at the center of the front side of the vertical rod 3. The connecting bearing 41 is connected to a threaded rod 42, and the threaded rod 42 is threadedly connected to a displacement plate 43. The left and right sides of the displacement plate 43 are fixedly connected to the bonding pressure plate 5. Two guide slide rods 44 are arranged vertically through the displacement plate 43. The ends of the guide slide rods 44 are fixedly connected to the vertical rod 3. The end of the threaded rod 42 away from the connecting bearing 41 is fixedly connected to a handle 45. The displacement drive assembly 4, through the cooperation of the threaded rod 42 and the guide slide rods 44, can precisely adjust the position of the bonding pressure plate 5, thereby driving the fixing plate 62 of the pressure bonding assembly 6 and the flexible protrusion 63 to squeeze the heat flow probe, making it tightly adhere to the wall surface, eliminating air gaps, and avoiding heat transfer interference. Compared with the difficult-to-control adhesion of tape, this significantly improves the accuracy of measurement data. The design of the flexible protrusion 63 can also adapt to heat flow probes of different shapes, enhancing compatibility.

[0029] Furthermore, the displacement plate 43 is provided with a threaded hole 46 and a guide slide hole 47, respectively. The threaded hole 46 is threadedly connected to the threaded rod 42, and the guide slide rod 44 passes through the guide slide hole 47.

[0030] Furthermore, the pressure bonding component 6 includes a plurality of equidistantly arranged extension posts 61 fixedly connected to the bonding pressure plate 5, and a fixing plate 62 fixedly connected to the end of the extension posts 61. A plurality of evenly distributed flexible protrusions 63 are provided on the side of the fixing plate 62 away from the extension posts 61.

[0031] It is worth noting that the positioning telescopic component 7 includes two left and right symmetrical fixed ears 71 fixed to the top of the fitting pressure plate 5. A movable rod 72 passes through the fixed ears 71. A movable plate 73 is connected to the end of the movable rod 72 near the square frame 1. A plurality of equally spaced slots 74 are provided on the side of the movable plate 73 away from the movable rod 72. A return spring 75 is connected between the movable plate 73 and the fixed ears 71. The return spring 75 is sleeved on the movable rod 72.

[0032] It is worth noting that the fixed ear 71 is provided with a positioning sliding hole 76 that matches the movable rod 72, and the movable rod 72 passes through the positioning sliding hole 76.

[0033] It is worth mentioning that the end of the movable rod 72 away from the movable plate 73 is threadedly connected to a limit block 77, and the diameter of the limit block 77 is larger than the diameter of the positioning sliding hole 76.

[0034] Working principle and process: First, place the wiring connecting the heat flow probe and the temperature sensor into the slot 74 of the positioning telescopic assembly 7. At this time, the heat flow probe and the temperature sensor are located in front of the fixed plate 62. Then, rotate the handle 45 of the displacement drive assembly 4 to drive the threaded rod 42 to rotate. Since the threaded rod 42 is threadedly connected to the displacement plate 43 and the guide slide rod 44 passes through the guide slide hole 47 to play a limiting role, the displacement plate 43 will move linearly along the guide slide rod 44, thereby driving the bonding pressure plate 5 to move towards the wall. When the bonding pressure plate 5 moves, the slot 74 of the top positioning telescopic assembly 7 will first contact the wall. At this point, the movable rod 72 is blocked by the wall and displaced within the positioning sliding hole 76 of the fixed ear 71, compressing the return spring 75; the bonding plate 5 continues to move until the fixed plate 62 of the bonding assembly 6 contacts the heat flow probe and temperature sensor, and presses and fixes them to the wall; after the test is completed, the handle 45 is rotated in the opposite direction to make the bonding plate 5 move the fixed plate 62 away from the wall, releasing the pressure on the heat flow probe and temperature sensor, and the return spring 75 pushes the movable rod 72 and the movable plate 73 to reset, remove the wire from the slot 74, and finally press the edge of the strong suction cup 2 to separate it from the wall and remove the fixing bracket.
