Description

Technical Field

[0001] This utility model relates to the field of building envelope technology, specifically to an easily adjustable device for testing the thermal performance of building envelope structures. Background Technology

[0002] The building envelope refers to the walls, doors, and windows that enclose the building space. It includes exterior walls, roofs, windows, balcony doors, exterior doors, as well as partition walls and entrance doors in unheated stairwells. It can effectively resist the impact of adverse environments. Thermal performance testing devices are needed to test the building envelope during its use.

[0003] Currently, a Chinese patent discloses a field testing device for the thermal performance of building envelope structures (authorization announcement number CN212893452U), comprising a left fixing component and a right fixing component. The left and right fixing components are inserted into the left and right sides of the sample to be tested. The left fixing component is connected to a quick-connect lifting device via a quick-connect buckle and a left lifting rope, and the right fixing component is connected to the quick-connect lifting device via a quick-connect buckle and a right lifting rope. The insertion and installation of the left and right fixing components, positioned opposite each other on both sides, provides better balance to the test sample, making it less prone to tilting during hoisting and movement. Furthermore, the insertion speed is fast, and the hoisting is stable and safe.

[0004] According to the above reference materials, the plug-in installation of the left and right fixed components arranged opposite each other on both sides of the above device provides better balance of the test sample, making it less prone to tilting during the hoisting and movement of the test sample. It also features fast plug-in speed and stable and safe hoisting. However, when testing the enclosure sample, the plug-in component does not provide ideal hoisting effect for different enclosure samples. The enclosure sample is prone to loosening, affecting the device's usability. It is also inconvenient to adjust and fix the enclosure sample according to its shape, thus reducing the testing effect of the enclosure structure thermal performance testing device.

[0005] Based on this, this utility model designs an easily adjustable thermal performance testing device for building envelopes to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an easily adjustable device for testing the thermal performance of building envelope structures.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An easily adjustable thermal performance testing device for building envelope includes two mounting frames, with a fixed plate slidably connected between the two mounting frames. The device further includes an adjustment mechanism disposed on the inner wall of the mounting frames. A clamping plate is slidably connected to the middle of the inner wall of the mounting frames, and a slider is fixedly connected to the bottom end of the clamping plate. The slider is slidably connected to the inner wall of the mounting frames. A lead screw is rotatably connected to the middle of the inner wall of the mounting frames, and the lead screw is threadedly connected to the slider. A telescopic component is provided on one side of the mounting frames.

[0009] Furthermore, the adjustment mechanism also includes a protective cover fixedly connected to both ends of the slider, and the other end of the protective cover is fixedly connected to the inner wall of the mounting bracket.

[0010] Furthermore, the inner wall of the mounting bracket is fixedly connected to two reinforcing rods, which extend through to the outer wall of the slider.

[0011] Furthermore, the two reinforcing rods are disposed on both sides of the lead screw.

[0012] Furthermore, a motor is mounted on one side of the mounting bracket, and one end of the lead screw passes through the mounting bracket and is fixedly connected to the output shaft at one end of the motor.

[0013] Furthermore, the telescopic assembly includes electric push rods installed on both sides of the bottom of the fixed plate, a fixed block is fixedly connected to the inner top wall of the mounting bracket, and one end of the electric push rod is fixedly connected to the fixed block.

[0014] Furthermore, two connecting rods are slidably connected between the two mounting brackets, with both ends of the connecting rods penetrating into the inner wall of the mounting bracket.

[0015] Furthermore, the two connecting rods are located on both sides of the clamping plate.

[0016] Furthermore, two anti-slip plates are fixedly connected to the inner bottom wall of the mounting bracket.

[0017] Furthermore, the two anti-slip plates are respectively installed on both sides of the clamp, and the top of the anti-slip plates is in contact with the enclosure template.

[0018] Beneficial effects

[0019] 1. The clamping plates at the bottom center of the two mounting brackets move by engaging with the grooves on the mounting brackets via sliders. This allows for the clamping and fixing of the enclosure template, and can also be adjusted according to the size of the enclosure template, improving the testing effect of the thermal performance testing device on the enclosure template. The two protective sleeves can extend and retract with the sliders, reducing the impact of external dust on the lead screw. The two reinforcing rods, in conjunction with the sliders, can reinforce the load capacity of the lead screw. In conjunction with the motor, they can stably drive the clamping plates, allowing for the adjustment and clamping of the enclosure template, and improving the testing effect of the thermal performance testing device.

[0020] 2. The two mounting brackets slide by engaging with protruding blocks on the inner wall of the fixed plate. One end of each of the two electric push rods cooperates with the fixed block to adjust the distance between the two mounting brackets, allowing for the placement of enclosure templates of different sizes. The two connecting rods enhance the stability of the mounting brackets and reinforce them. The anti-slip plate increases the friction between the mounting brackets and the enclosure templates, improving the testing stability of the enclosure templates and enhancing the testing accuracy of the thermal performance testing device.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 An easily adjustable thermal performance testing device for building envelope includes two mounting brackets 100, with a fixed plate 200 slidably connected between the two mounting brackets 100. It also includes an adjustment mechanism 300, which is disposed on the inner wall of the mounting brackets 100. A clamping plate 310 is slidably connected to the middle of the inner wall of the mounting brackets 100, and a slider 320 is fixedly connected to the bottom end of the clamping plate 310. The slider 320 is slidably connected to the inner wall of the mounting brackets 100. A lead screw 330 is rotatably connected to the middle of the inner wall of the mounting brackets 100, and the lead screw 330 is threadedly connected to the slider 320. A telescopic component 370 is provided on one side of the mounting brackets 100.

[0031] It should be noted that the thermal performance testing device for the building envelope consists of a testing instrument, a temperature sensor, a support assembly, a frame, an adjustment assembly, and a control system assembly. When testing the building envelope sample, the sample is placed on the support assembly for placement and testing. The sample is then fixed in place by the adjustment assembly. The testing instrument and temperature sensor contact the sample fixed on the support assembly. The control system drives the testing instrument and temperature sensor to test the sample. The clamping plate 310 within the adjustment mechanism 300 is connected to the lead screw 330 via the bottom slider 320. The telescopic component 370 can clamp and fix the enclosure template. When the enclosure template is placed for testing, the telescopic component 370 can drive the electric push rod 371 to cooperate with the fixing block 372 to adjust the distance between the two mounting brackets 100. Different enclosure templates can be placed. The telescopic component 370 can fix the enclosure template in cooperation with the two clamps 310 on the adjustment mechanism 300. The adjustment mechanism 300 and the telescopic component 370 are both part of the thermal performance testing device. They can optimize the thermal performance testing device and will not affect the normal use of the thermal performance testing device for the enclosure structure.

[0032] The enclosure template is placed on two mounting brackets 100. The control system drives the two motors 360 in the adjustment mechanism 300 to operate. One end of the motor 360 drives the lead screw 330 to rotate and is threadedly connected to the slider 320. The slider 320 moves the clamping plate 310 from one side to the middle along the groove on the mounting bracket 100 to clamp and fix the enclosure template. The clamping plates 310 on both sides of the mounting bracket 100 contact the bottom of the enclosure template on both sides and clamp the enclosure template. The tester and temperature sensor contact the upper surface of the enclosure template to test the thermal performance of the enclosure template. The two mounting brackets 100 are adjusted and installed according to the enclosure template of different sizes through the adjustment mechanism 300 and the telescopic component 370, which improves the use effect of the enclosure structure thermal performance testing device.

[0033] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, the adjustment mechanism 300 further includes a protective cover 340 fixedly connected to both ends of the slider 320, and the other end of the protective cover 340 is fixedly connected to the inner wall of the mounting bracket 100.

[0034] When the slider 320 moves the clamping plate 310 to one side, the protective covers 340 on both sides of the slider 320 extend and deform with the movement of the slider 320, which can protect the lead screw 330 and reduce the influence of external impurities on the lead screw 330.

[0035] In this embodiment of the utility model, two reinforcing rods 350 are fixedly connected to the inner wall of the mounting bracket 100, and the reinforcing rods 350 penetrate to the outer wall of the slider 320.

[0036] When the lead screw 330 drives the slider 320 to move, the slider 320 slides to one side along the outer wall of the two reinforcing rods 350. The two reinforcing rods 350 can support and guide the slider 320, improving the stability of the slider 320's movement.

[0037] In this embodiment of the invention, two reinforcing rods 350 are disposed on both sides of the lead screw 330.

[0038] Two reinforcing rods 350 are distributed on both sides of the lead screw 330. In conjunction with the slider 320, they can reduce the impact of the load on the lead screw 330 and prevent the lead screw 330 from jamming.

[0039] In this embodiment of the utility model, a motor 360 is installed on one side of the mounting bracket 100, and one end of the lead screw 330 passes through the mounting bracket 100 and is fixedly connected to the output shaft of one end of the motor 360.

[0040] The motor 360 on one side of the mounting bracket 100 is driven by the control system. The motor 360 can drive the lead screw 330 to rotate, so that the lead screw 330 can drive the clamping plate 310 on the slider 320 to move to one side to clamp the enclosure template. The position of the clamping plate 310 can also be adjusted.

[0041] In some embodiments, such as Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the telescopic component 370 includes an electric push rod 371 installed on both sides of the bottom of the fixed plate 200, and a fixed block 372 is fixedly connected to the inner top wall of the mounting bracket 100. One end of the electric push rod 371 is fixedly connected to the fixed block 372.

[0042] The control system drives the electric push rods 371 on both sides of the bottom of the fixed plate 200 to run. One end of the electric push rod 371 cooperates with the fixed block 372 to drive the mounting frame 100 to move to one side along the inner wall of the fixed plate 200. The distance between the two mounting frames 100 can be adjusted, and larger enclosure templates can be installed and fixed. The two mounting frames 100 can be adjusted according to the enclosure template to improve the use effect of the thermal performance testing device.

[0043] In this embodiment of the utility model, two connecting rods 373 are slidably connected between the two mounting brackets 100, and both ends of the connecting rods 373 penetrate into the inner wall of the mounting bracket 100.

[0044] When the two mounting brackets 100 move to both sides, the two connecting rods 373 can reinforce the two mounting brackets 100 and improve the stability of the mounting brackets 100.

[0045] In this embodiment of the utility model, two connecting rods 373 are disposed on both sides of the clamping plate 310.

[0046] Two connecting rods 373 are respectively set at both ends of the bottom of the mounting bracket 100, which can reinforce the two mounting brackets 100 and improve the support strength of the mounting bracket 100.

[0047] In this embodiment of the utility model, two anti-slip plates 374 are fixedly connected to the inner bottom wall of the mounting bracket 100.

[0048] The two anti-slip plates 374 on the inner bottom wall of the mounting bracket 100 can contact the enclosure template to improve the friction effect between the enclosure template and the mounting bracket 100, prevent displacement of the enclosure template during testing, and improve the testing effect of the thermal performance testing device.

[0049] In this embodiment of the utility model, two anti-slip plates 374 are respectively disposed on both sides of the clamping plate 310, and the top of the anti-slip plate 374 is in contact with the enclosure template.

[0050] Two anti-slip plates 374 are distributed on both sides of the clamping plate 310 and are in contact with the enclosure template, which can protect the enclosure template and prevent the enclosure template from shifting during inspection.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
