Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment, specifically a complex airflow simulation generating device for testing filter absorbers. Background Technology
[0002] The air delivery and airflow temperature and humidity control module mainly includes an air filter, dehumidifier, air heater, frequency converter, high-pressure turbine centrifugal fan, and flow meter. First, air passes through the filter and then enters the dehumidifier for dehumidification. After dehumidification, the air enters the air heater for preheating to a preset temperature before entering the mixing system. The airflow is controlled by adjusting the turbine fan speed via the frequency converter. For the initial purification of temperature, humidity, and airflow, an integrated design is used, combining the air filter, dehumidifier, and air heater into the constant temperature and humidity control equipment. Controlling the constant temperature and humidity control equipment achieves the desired temperature, humidity, and airflow temperature and humidity control. The system controls temperature, humidity, and airflow. For parameters such as air volume and air delivery, an integrated design is employed, incorporating a frequency converter, high-pressure turbine centrifugal fan, and flow meter into the air volume testing device. This device controls system air volume and air delivery parameters using a nozzle method, resulting in higher accuracy and more precise control. The module features an integrated design, with the constant temperature and humidity unit and air volume testing device working together, all controlled by a PLC module. All parameters can be displayed and operated on the PLC module control terminal system.
[0003] A keyboard bracket is fixed to the side frame of the airflow testing device to hold the keyboard operating system. However, the bracket extends too far and is prone to snagging on the clothing of the testers or causing collisions when not in use. Therefore, a complex airflow simulation device for filter absorber testing is proposed to address the above problems. Utility Model Content

[0011] The advantages of this utility model are:
[0012] 1. This utility model uses the pressing of the steering support frame to make the irregular groove clamp the limiting cut edge column. The cut edge on the side of the limiting cut edge column will block the side of the irregular groove, so that the steering support frame cannot rotate. At this time, the steering support frame is fixed.
[0013] 2. In this utility model, the elastic clip is driven by a spring that is deformed by the previously inserted post.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0026] This application discloses a complex airflow simulation device for testing filter absorbers, including an airflow testing device 1. A positioning frame 2 is fixedly connected to the front side of the housing of the airflow testing device 1. A steering support frame 3 is slidably connected to the upper part of the positioning frame 2. A shaped groove 7 is opened on the side of the rear end of the steering support frame 3 and is slidably connected to the frame of the positioning frame 2. A support plate 6 is inserted into the frame of the steering support frame 3, and a pin 4 is inserted between the support plate 6 and the steering support frame 3 for fixing.
[0027] The positioning frame 2 includes: a limiting cutting post 21 and a receiving groove 22. The upper part of the positioning frame 2 is fixedly connected to the end of the limiting cutting post 21, and the receiving groove 22 is opened on the front side of the positioning frame 2.
[0028] The steering support frame 3 includes: a fitting groove 31, a slot 32, and a socket 33. The fitting groove 31 is provided on the top of the steering support frame 3, the slot 32 is provided on the front side of the fitting groove 31, and the socket 33 is provided on the side of the steering support frame 3.
[0029] The insertion pin 4 includes: a post 41 and a through hole 42. The end of the insertion pin 4 is fixedly connected to the end of the post 41, and the post 41 has a through hole 42.
[0030] The support plate 6 includes: an L-shaped clamping plate 61, a clamping handle 62, an insertion hole 621, and an elastic clamping head 633. The plate body of the support plate 6 is fixedly connected to the plate body of the L-shaped clamping plate 61, and the plate body of the L-shaped clamping plate 61 is fixedly connected to the end of the clamping handle 62. The frame of the clamping handle 62 has an insertion hole 621, and the inner wall of the insertion hole 621 is provided with an elastic clamping head 633.
[0031] The elastic clip 633 includes a limiting hole 631 and a spring 632. The limiting hole 631 is formed in the inner wall of the insertion hole 621. One end of the elastic clip 633 is fixedly connected to one end of the spring 632, and the other end of the spring 632 is fixedly connected to the inner wall of the limiting hole 631.
[0032] Working principle: When support is needed for the keyboard, first rotate the steering support frame 3 90 degrees, then press the steering support frame 3 down. At this time, the irregular groove 7 will slide against the limiting cut edge post 21, so that the lowest end of the irregular groove 7 moves to the middle bend of the irregular groove 7. During this process, the steering support frame 3 also inserts into the inner wall of the positioning frame 2. As the steering support frame 3 is pressed, the irregular groove 7 is locked with the limiting cut edge post 21. The cut edge on the side of the limiting cut edge post 21 will block the side of the irregular groove 7, so that the steering support frame 3 cannot rotate. At this time, the steering support frame 3 is fixed.
[0033] Then, align the L-shaped locking plate 61 with the fitting groove 31 and press the support plate 6 so that the L-shaped locking plate 61 is inserted into the fitting groove 31 and the locking handle 62 is inserted into the slot 32. At this time, insert the pin 41 into the insertion hole 33. The pin 41 will be inserted into the through hole 621. When the through hole 42 moves due to the movement of the pin 41, the through hole 42 will be aligned with the elastic locking head 633. At this time, the elastic locking head 633 will be driven by the spring 632 that was previously squeezed and deformed by the pin 41. The spring 632 drives the elastic locking head 633 to be inserted into the through hole 42, thus completing the locking of the pin 4. The pin 4 can also limit the locking handle 62 and the steering support frame 3, so that the support plate 6 can maintain the pressure state.
[0034] The insertion of the fitting groove 31 and the L-shaped card plate 61 can provide an anchor point for the support plate 6, preventing the end of the support plate 6 from warping when under pressure. The insertion of the insertion hole 33 and the insertion pin 4 can be quickly disassembled. The insertion pin 4 can be inserted into the insertion hole 33 in different directions. The setting of the receiving groove 22 can allow the support plate 6 to be inserted back into the frame of the steering support frame 3 after the steering support frame 3 is folded, avoiding interference between the positioning frame 2 and the support plate 6, so that the two fit together and prevent other items from being hung.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
