For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0024] As Figures 1 to 5 shown, the building door and window heat preservation performance detection device includes the main body 1 of the detection device, the cold pressing mechanism 5 and the control cabinet 7. A detection cold box 3, a specimen frame 2 and a detection hot box 4 are arranged in the main body 1 of the detection device. The output end of the cold pressing mechanism 5 is communicated with the air inlet end of the detection cold box 3. The main body 1 of the detection device is signal-connected to the control cabinet 7. A detection cold cavity 15 is arranged in the detection cold box 3, a specimen placing mechanism and a communication cavity 14 are arranged in the specimen frame 2, a heating mechanism and a detection hot cavity 16 are arranged in the detection hot box 4, the communication cavity 14 is respectively communicated with the detection cold cavity 15 and the detection hot cavity 16, a specimen door and window 22 is fixed in the adjustable specimen placing mechanism, and a ventilation mechanism is arranged above the main body 1 of the detection device. The ventilation mechanism is communicated with the detection hot box 4 and the specimen frame 2.

[0025] The purpose of such a design is that the adjustable specimen placement mechanism can be reasonably fixed according to the size of the specimen doors and windows to be detected, which can be applied to the detection of various doors and windows, and solves the problem that the existing building door and window heat preservation performance detection devices mostly use placement mechanisms with fixed sizes and it is difficult to detect doors and windows of various sizes.

[0026] It should be noted that in this embodiment, the cold pressing mechanism is usually a cold press, which is connected to the detection cold cavity through a cold air input pipe. At the same time, the control cabinet controls the inside of the detection device body and the cold pressing mechanism through a data line. The control method is prior art, and those skilled in the art can assemble the corresponding circuit according to the circuit connection relationship, and this embodiment does not improve the part of the circuit connection method either.

[0027] In this embodiment, the ventilation mechanism includes an intake main pipe 23 and an exhaust main pipe 11. The intake main pipe 23 is connected to the detection hot cavity 16 through an intake pipe 13, and the exhaust main pipe 11 is connected to the communication cavity 14 through an exhaust pipe 12.

[0028] The purpose of such a design is that during the detection work, the cold air input from the cold pressing mechanism can enter the communication cavity and then be discharged to the exhaust main pipe through the exhaust pipe. At the same time, the air input from the intake pipe can drive the hot air heated by the heating mechanism to flow, and be discharged to the exhaust main pipe through the communication cavity and the exhaust pipe.

[0029] Furthermore, in this embodiment, the heating mechanism includes heating pipes 17 arranged on the inner wall of the detection hot box 4.

[0030] At the same time, in this embodiment, the specific composition of the adjustable practice placement mechanism is provided. The adjustable specimen placement mechanism includes a first limiting member 18 and a second limiting member 19. The first limiting member 18 and the second limiting member 19 are in a cover structure. The first limiting member 18 is connected to the first movable rod 10, and the first movable rod 10 passes through the detection cold cavity 15. The second limiting member 19 is connected to the second movable rod 9, and the second movable rod 9 passes through the detection hot cavity 16. The end of the first limiting member 18 is located in the communication cavity 14, and a protrusion is provided at the end of the first limiting member 18, and the protrusion restricts the first limiting member 18 from completely entering the detection cold cavity 15. The end of the second limiting member 19 is located in the communication cavity 14, and a protrusion is provided at the end of the second limiting member 19, and the protrusion restricts the second limiting member 18 from completely entering the detection hot cavity 16. Both ends of the specimen door and window 22 are abutted against the first limiting member 18 and the second limiting member 19 respectively. A first through hole 20 is provided on the first limiting member 18, and during operation, the first through hole 20 can connect the detection cold cavity 15 and the communication cavity 14. A second through hole 21 is provided on the second limiting member 19, and during operation, the second through hole 21 can connect the detection hot cavity 16 and the communication cavity 14.

[0031] The purpose of such a design is that the structures of the first limiting member and the second limiting member are usually U-shaped. Then, the adapted movable rod is connected to the middle of the U-shaped structure, and the open end of the U-shaped structure faces the test piece door and window.

[0032] At the same time, the first movable rod and the second movable rod pass through the testing device. The user can push the handle at the end of the movable rod to move the positions of the first limiting member and the second limiting member. Usually, there are sealing rings at the places where the first movable rod and the second movable rod pass through the testing device.

[0033] Furthermore, although the communication cavity is communicated with the detection hot cavity and the detection cold cavity, the first limiting member and the second limiting member are respectively arranged at the communication places. Since there are protruding parts at the ends of the first limiting member and the second limiting member, the two limiting members cannot be completely inserted into the detection hot cavity or the detection cold cavity.

[0034] Due to the provision of the first through hole and the second through hole, it can be switched among multiple working modes, such as Figure 3 In the case of simulating an outdoor cold environment and an indoor hot environment at the same time, and cold wind acting on the door and window. At this time, the user first pulls the first movable rod away from the testing device, and then pushes the second movable rod towards the testing device, so that under the action of the protruding part, the first limiting member cannot enter the detection cold cavity, while the first through hole enters the detection cold cavity. At this time, the cold air input by the cold pressing mechanism enters the detection cold cavity, then enters the communication cavity from the first through hole, and is discharged from the air outlet pipe. The detection hot cavity continues to heat to simulate the hot scenario, and at this time the cold wind acts on the test piece door and window.

[0035] Such as Figure 4 In the case of simulating an outdoor hot environment and an indoor cold environment at the same time, and hot wind acting on the door and window. At this time, the user first pushes the first movable rod towards the testing device, and then pulls the second movable rod away from the testing device, so that under the action of the protruding part, the second limiting member cannot enter the detection cold cavity, while the second through hole enters the detection hot cavity. At this time, the gas input by the air inlet pipe drives the heated air by the heating mechanism to flow, then enters the communication cavity from the second through hole, and is discharged from the air outlet pipe. The detection cold cavity pauses working and relies on the remaining cold air for simulation, or slowly inputs cold air with a reduced power. At this time, the hot wind acts on the test piece door and window.

[0036] It should also be pointed out that Figure 3 and Figure 4 The placement form of the test piece door and window in is only one case. In actual use, in this field, the test piece door and window can also be longitudinally placed in a way perpendicular to the figure, so as to realize a state similar to facing the wind to test the cold wind and the hot wind. The principle is the same as the above description, only the specific implementation methods are different. Those skilled in the art can adjust according to actual needs and will not be elaborated here.

[0037] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
