The left end of the connecting rod 7 is fixedly connected to the pressing plate 8, and the surface material of the pressing plate 8 is rubber.

[0033] Reference Figure 2 - Figure 4 The shell 2 is connected to the base 1 through a height adjustment mechanism 9. The height adjustment mechanism 9 includes a motor 91. The bottom end of the motor 91 is fixedly connected to the inner wall of the base 1. The output shaft of the motor 91 is fixedly connected with a screw 92. The screw 92 passes through the inner wall of the base 1. There is no connection between the screw 92 and the inner wall of the base 1. The outer wall of the screw 92 passes through and is threadedly connected with a height adjustment block 93. The inner wall of the height adjustment block 93 is provided with a threaded groove. The top of the height adjustment block 93 is hinged to the bottom end of the shell 2. The inner wall of the base 1 is fixedly connected with a sliding rod 94. The outer wall of the sliding rod 94 passes through the inner wall of the base 1. The outer wall of the sliding rod 94 is slidably connected with a height adjustment block 2 95. The screw 92 is consistent with the sliding rod 94 in height. The outer wall shape of the height adjustment block 1 93 is consistent with that of the height adjustment block 2 95. Through the consistent shape, it is ensured that the supporting force generated by the height adjustment block 1 93 and the height adjustment block 2 95 on the shell 2 is consistent. The top of the height adjustment block 2 95 is hinged to the bottom end of the shell 2.

[0034] Reference Figure 2 - Figure 4The sliding rod 94 is fixed to the height adjustment block 2 95 by a fixing assembly 96. The fixing assembly 96 includes an air pressure tube 1 961. The air pressure tube 1 961 penetrates and is fixedly connected to the inner wall of the sliding rod 94. The shape of the air pressure tube 1 961 is L-shaped. The piston on the inner wall of the lower end of the air pressure tube 1 961 is connected to a slide 962. The side wall of the slide 962 is made of rubber. The right end of the slide 962 is rotatably connected to a threaded rod 963. The outer wall of the threaded rod 963 penetrates and is fixedly connected to the inner wall of the lower right end of the air pressure tube 1 961. Threaded connection, a threaded groove is provided at the lower right end of the air pressure tube 961, and an air bag 964 is fixedly connected to the outer wall of the air pressure tube 961. The shape of the air bag 964 is an approximately circular arc. The air bag 964 does not contact the sliding shaft that is slidably connected to the sliding rod 94 and the height adjustment block 2 95. The shape setting of the air bag 964 ensures that the air bag 964 can fill the gap between the sliding rod 94 and the height adjustment block 2 95 completely, and the outside of the air bag 964 is connected to the inside of the air pressure tube 961.

[0035] Reference Figure 2 and Figure 5 The height adjustment block 1 93 is connected to the height adjustment block 2 95 through a unified component 97. The unified component 97 includes a connecting rod 1 973. The left end of the connecting rod 1 973 is hinged to the right end of the height adjustment block 1 93. The right end of the connecting rod 1 973 is fixedly connected to a sliding piece 972. The outer wall piston of the sliding piece 972 is connected to an air pressure tube 2 971. The interior of the air pressure tube 2 971 is filled with gas. The inner wall piston of the air pressure tube 2 971 at the right end of the sliding piece 972 is connected to a sliding block 974. The outer walls of the sliding piece 972 and the sliding block 974 are tightly fitted with the inner wall of the air pressure tube 971. The sliding piece 972 and the sliding block 974 are consistent in shape and size, and the outer walls of the sliding piece 972 and the sliding block 974 are made of rubber. Through the setting of the material, it is ensured that the gas on both sides of the sliding piece 972 and the sliding block 974 cannot circulate. The right end of the sliding block 974 is fixedly connected with the connecting rod 975, and the right end of the connecting rod 975 is hinged to the left end of the height adjustment block 95.

[0036] Working principle: When in use, the staff first moves the equipment to the test position, and then adjusts the height and angle of the pressing plate 8 as needed.

[0037] When it is necessary to conduct a wind pressure test on the curtain in an inclined direction, the staff first rotates the threaded rod 963 so that the threaded rod 963 drives the sliding piece 962 to move in the direction of entering the air pressure tube 1 961, so that the gas inside the air pressure tube 1 961 enters the interior of the air bag 964 under the push of the sliding piece 962, thereby causing the air bag 964 to expand. At this time, the gap between the sliding rod 94 and the height adjustment block 2 95 is filled with the air bag 964, so the height adjustment block 2 95 and the sliding rod 94 cannot move relative to each other.

[0038] At this time, the staff starts the motor 91, so that the motor 91 drives the screw 92 to rotate, thereby changing the height of the height adjustment block 1 93, so that the height of the height adjustment block 1 93 is inconsistent with the height of the height adjustment block 2 95, thereby achieving the effect of changing the angle of the shell 2.

[0039] When the wind pressure test of the curtain needs to be carried out in the horizontal direction, the staff first rotates the threaded rod 963 in the opposite direction, so that the sliding piece 962 moves to the right, thereby reducing the air pressure inside the air pressure tube 1 961, so that the gas inside the air bag 964 enters the inside of the air pressure tube 1 961, thereby reducing the friction between the sliding rod 94 and the height adjustment block 2 95, so that the height adjustment block 2 95 can slide up and down at this time.

[0040] Since the initial state of the air pressure tube 971 is horizontal, when the heights of the height adjustment block 93 and the height adjustment block 95 are inconsistent, the connecting rod 973 and the connecting rod 975 are pulled, so that the pressure in the area between the left end of the sliding plate 972 and the right end of the sliding block 974 increases, and the pressure between the sliding plate 972 and the sliding block 974 decreases. Therefore, when the height adjustment block 95 is released from the limit, the height adjustment block 95 can move to a position horizontal with the height adjustment block 93 under the action of air pressure.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
