[0002] The fan coil unit is one of the terminal devices of the air conditioning system, which is composed of a small fan, a motor and a coil (air heat exchanger). When chilled water or hot water flows through the coil tube, it exchanges heat with the air outside the tube, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters. It is a commonly used cooling and heating terminal device.
[0003] Fan coil units can be divided into vertical, horizontal, wall-mounted, and cassette types according to their structural forms. Air volume tests are required before leaving the factory.

[0022] In order to more clearly explain the overall concept of this application, the following Figure 1-4 This application is described in further detail.
[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features in each embodiment may be combined with each other without conflict.
[0024] The present application embodiment discloses a fan coil unit detection device. Figure 1 , Figure 2 and Figure 4A fan coil unit detection device includes a test mechanism and an adjustable joint mechanism 100. The test mechanism is connected to the fan coil unit through the adjustable joint mechanism, and the air outlet of the fan coil unit is detected by the test mechanism. The adjustable joint mechanism 100 includes an air guide box 200, a steering assembly 300 and an adjustment assembly 400. An air inlet 210 for connecting the fan coil unit is provided at one end of the air guide box 200 in the height direction, and an air outlet 220 is provided at the other end of the air guide box 200 in the height direction. The air outlet 220 is used to communicate with the test mechanism. The steering assembly 300 is connected to the air guide box 200. The adjustment component 400 is used to adjust the air outlet area of the air outlet 220. The adjustment component 400 includes two symmetrically arranged guide plates 410. The guide plates 410 are slidably connected between the two side walls in the width direction of the air guide box 200. One end of the guide plate 410 slides along the height direction of the air guide box 200, and the other end of the guide plate 410 slides along the length direction of the air guide box 200.
[0025] The fan coil unit is connected to the test mechanism by using the air guide box 200, and the steering assembly 300 is used to rotate the air guide box 200, so as to realize different orientations of the air inlet 210 of the air guide box 200, thereby realizing the connection of fan coil units with different structures. The guide plates 410 are connected between the two side walls in the width direction of the air guide box 200, and the two guide plates 410 are used to block part of the air outlet 220. The air outlet area of the air outlet 220 can be adjusted by sliding the two guide plates 410, and a set of detection interfaces can be used to test the air volume of fan coil units of various specifications such as vertical, horizontal, wall-mounted, and card-type.
[0026] In addition, the two guide plates 410 are in a tilted state during the process of guiding the air, so the wind noise when the air flows through the air guide box 200 is small, which reduces the vibration of the air guide box 200 and improves the stability of the connection between the air guide box 200 and the fan coil unit and the testing mechanism.
[0027] Reference Figure 1 and Figure 3 Slide rails 230 are provided on both side walls of the air guide box 200 in the width direction, and a pin shaft 420 is fixedly connected to the end of the guide plate 410 . The pin shaft 420 is inserted into the slide rails 230 and slides along the slide rails 230 .
[0028] The guide plate 410 is slidably connected between the two side walls of the air guide box 200 in the width direction through the cooperation of the pin shaft 420 and the slide rail 230. The slide rail 230 is used to limit the movement of the guide plate 410 to improve the stability of the connection between the guide plate 410 and the air guide box 200.

[0032] The cross-sectional areas of the air intake section, the guide section and the exhaust section perpendicular to the height direction of the air guide box 200 gradually increase, thereby expanding the adjustment range of the air outlet area and improving the applicability of the detection device. In addition, a guide section is arranged between the air intake section and the exhaust section to further reduce wind noise.
[0033] Reference Figure 3 The guide plate 410 is connected to a driving assembly 500 , and the driving assembly 500 is slidably connected to the pin shaft 420 . The driving assembly 500 is used to limit the movement of the guide plate 410 .
[0034] The driving assembly 500 includes an electric push cylinder 510 and a transmission rod 520. The two guide plates 410 are connected to the transmission rod 520 through a pin shaft 420.

The piston rod of the electric push cylinder 510 is fixedly connected to the transmission rod 520. The extension direction of the piston rod of the electric push cylinder 510 is parallel to the height direction of the air guide box 200.
[0035] By installing the electric push cylinder 510 on the side wall of the air guide box 200, when the air outlet area of the air outlet 220 needs to be adjusted, the piston rod of the electric push cylinder 510 is extended and retracted to drive the two guide plates 410 to rotate, thereby adjusting the air outlet area of the air outlet 220. Reference Figure 2 The steering assembly 300 includes a support base 310, a motor and a rotating shaft 320. The rotating shaft 320 is rotatably connected to the support base 310. The motor is transmission-connected to the rotating shaft 320 through a gear transmission structure, and the rotating shaft 320 is connected to the air guide box 200.
[0036] The rotating shaft 320 is elastically connected to the air guide box 200 through an elastic rod. The elastic rod includes a first rod 330, a second rod 340 and a spring. The first rod 330 is fixedly connected to the rotating shaft 320, the second rod 340 is fixedly connected to the air guide box 200, one end of the second rod 340 away from the air guide box 200 is inserted through one end of the first rod 330 away from the rotating shaft 320, and the second rod 340 is connected to the first rod 330 through the spring.
