[0002] In real life, the heat dissipated through the external doors and windows of buildings wastes a great deal of energy. At present, the country is strongly developing a conservation-minded society, and popularizing energy-saving buildings is an urgent aspect. The country has put forward strict mandatory indicators for the heat insulation performance of external doors and windows of buildings. At the same time, choosing external doors and windows with better heat insulation performance can reduce the energy dissipated through the external doors and windows of buildings.

[0003] The patent with the publication number CN213148791U discloses a heat transfer coefficient detection device for doors and windows, which includes a base. A detection main box is fixed at the upper end of the base. The detection main box is composed of a lower box body and an upper box body. A sealing ring is installed at the connection between the lower box body and the upper box body. A heating pipe is installed inside the lower box body. A first temperature sensor is installed on the side wall of the lower box body. A placement pad is fixedly installed on the side wall of the lower box body. A door and window body is arranged on the placement pad. An installation frame is fixed at the inner bottom end of the upper box body. A rotating motor is installed at the inner top end of the installation frame. The output end of the rotating motor is connected with a threaded rod. A lifting plate is threadedly installed on the threaded rod. A connecting rod is fixed at the lower end of the lifting plate. A pressing plate is fixed at the lower end of the connecting rod. A support rod is installed at the upper end of the base. A cross bar is fixed at the upper end of the support rod. An electric telescopic rod is fixed at the lower end of the cross bar. The lower end of the electric telescopic rod is fixed to the upper box body. The utility model is convenient for detecting the heat transfer coefficient of doors and windows with different thicknesses and is easy to use.

[0004] However, heat transfer coefficient detection devices for doors and windows such as the above have a relatively complex structure, which will cause waste of resources. When using this device to detect doors and windows with different thicknesses, its fixing method is also relatively cumbersome, not simple and direct enough. It is also very inconvenient to take and place the horizontally placed detection parts. Moreover, due to the existence of the pressing plate, it is likely to have a certain impact on the detection results.

[0034] As Figure 1-7As shown, the utility model provides a door and window heat transfer coefficient detection device, including a detection frame 1, the detection frame 1 provides a fixing and detection space for the detection of doors and windows, so as to facilitate the detection of the doors and windows to be detected, a detection fixing plate 12 is provided in the middle of the detection frame 1, the detection fixing plate 12 divides the inside of the detection frame 1 into two different detection areas, thereby facilitating the detection of the door and window heat transfer coefficient, a detection fixing groove 121 is provided in the middle of the detection fixing plate 12, a door and window detection member 4 is placed in the detection fixing groove 121, and the door and window detection member 4 can be stably placed in the middle of the detection frame 1, In order to reduce the influence of external conditions on the detection results as much as possible, four fixing components 3 for fixing the door and window detection parts 4 are arranged around the detection fixing groove 121. The fixing components 3 can firmly squeeze the door and window detection parts 4 in the inspection fixing groove 121 from all sides, thereby ensuring the sealing of both sides of the door and window detection parts 4. The right sides of the front and rear ends of the detection frame 1 are rotatably connected with sealing cover plates 2 respectively. The inner side of the sealing cover plate 2 is provided with a temperature detector 5 and a temperature control part 6 from top to bottom, and the temperature control part 6 can be divided into a heater 61 on the front sealing cover plate 2 and a cooler 62 on the rear sealing cover plate 2.

[0035] In the above scheme, the fixing assembly 3 includes a resistance block 31, a fixing plate 32 and an adjusting rod 33. The detection fixing groove 121 is connected to the outside of the sliding groove 122. The adjusting rod 33 is threadedly connected to the fixing plate 32. The resistance block 31 is slidably connected in the sliding groove 122 and rotatably connected to the inside of the adjusting rod 33.

[0036] As an optimization technical solution of the utility model, by twisting the adjusting rod 33, the resistance block 31 can be driven to slide in and out of the sliding groove 122, and then the door and window detection part 4 placed in the detection fixing groove 121 can be clamped from all sides to complete the fixation of the door and window detection part 4, so as to facilitate the detection of its heat transfer coefficient.

[0037] In the above solution, an inclined contact surface 311 is provided on the inner side of the head of the contact block 31 , and the inclined contact surface 311 contacts the edge of the door and window detection member 4 .

[0038] As an optimization technical solution of the utility model, the inclined contact surface 311 provided at the head of the contact block 31 forms a block structure with a small head and a large tail, so that when door and window detection parts 4 of different thicknesses are placed in the detection fixing groove 121, the door and window detection parts 4 of different thicknesses can be fixed by the interference with the inclined surface of the inclined contact surface 311 at different positions.

[0039] In the above solution, a sealing strip 23 is provided at the inner edge position of the sealing cover plate 2, and a sealing groove 11 is provided at the edge position of the detection frame body 1.

A control display screen 21 is provided at the upper end of the outer side of the sealing cover plate 2, and the control display screen 21 is connected to the temperature detector 5 and the temperature control member 6.

[0040] As an optimized technical solution of the present utility model, when the sealing cover plate 2 covers the detection frame body 1, the sealing strip 23 will be stuck in the sealing groove 11 to form a sealed detection space inside the detection frame body 1. Then, the temperature on both sides of the door and window detection member 4 inside the detection frame body 1 can be controlled through the temperature control member 6, and the temperature on both sides of it can be monitored in real time through the temperature detector 5 and displayed on the control display screen 21 in real time, so as to obtain the final detection result.

[0042] As an optimized technical solution of the present utility model, the through groove 123 is beneficial to achieve the heat transfer effect through the door and window detection member 4, so as to determine the heat transfer coefficient of the door and window detection member 4, and the setting of the sealing buffer ring 7 can ensure the sealing performance of the fixed position of the door and window detection member 4.

[0043] Specific implementation case:

[0044] During use, the sealing cover plate 2 is opened through the door handle 22, the door and window detection member 4 is placed on the sealing buffer ring 7 in the detection fixing groove 121, and then the adjusting rod 33 is twisted to make the abutting block 31 approach the door and window detection member 4 until the inclined abutting surface 311 abuts against the edge position of the door and window detection member 4. By abutting and squeezing different positions of the inclined abutting surface 311 with different thicknesses of the door and window detection member 4, the fixing of the door and window detection member 4 can be realized, so as to improve the detection accuracy.

[0045] Then, the sealing cover plate 2 is covered on both sides of the detection frame body 1, so that the sealing strip 23 is stuck into the sealing groove 11 to form two different temperature detection areas on both sides of the detection frame body 1. After the sealing cover plate 2 is covered tightly, heating is realized through the heater 61 provided on the front sealing cover plate 2, and cooling is realized through the cooler 61 provided on the rear sealing cover plate 2 through the control display screen 21. Then, after the heat transfer process is stable, the temperature detector 5 records it successively through the control display screen 21 at the same interval of time.

[0046] Finally, the temperature data successively recorded by the control display screen 21 is calculated according to the heat transfer coefficient formula to obtain the average value, and the operation is simple and the detection is convenient.

[0047] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model.
