Description

[0002] With the development of science and technology, various modern building roofs have emerged, such as thin metal roofs, membrane structure roofs, glass daylighting domes, etc. To ensure that the products meet the production standards, the above all need to undergo strict comprehensive tests on airtightness, watertightness, static wind load, and dynamic wind load performance. However, when the existing detection devices test the test piece, it is necessary to frequently move the static pressure box to clamp the test piece. The movement of the static pressure box will cause the bellows and its components connected to it to move together. The bellows that are frequently moved and opened and closed are extremely prone to damage. Due to its complex installation and connection, it will become very laborious to disassemble and assemble the bellows, with inconvenient operation, time-consuming and laborious. Moreover, due to the lack of positioning and fixing functions, when the static pressure box clamps the test piece, the test piece is very likely to move in position, affecting the detection and reducing the detection accuracy, bringing many troubles to the staff.

The elastic force of the first spring 113 can cause the pressure plate 114 to apply pressure to the bottom. When contacting the workpiece to be tested, the pressure plate 114 can first press against the workpiece to be tested to press it tightly and fix it to avoid movement. The outer sides of the lower static pressure box 2 and the upper static pressure box 10 are both equipped with a disassembly mechanism 12, and the disassembly mechanism 12 includes a first connecting seat 121, and the first connecting seat 121 is installed on the outer sides of the lower static pressure box 2 and the upper static pressure box 10.

[0023] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0024] During use, turn on the motor 4. The motor 4 drives the round rod 5 to rotate, and the sprocket 6 mounted on the round rod 5 uses the chain 7 to cause the sprocket 6 on the screw rod 3 to drive the screw rod 3 to rotate together. The rotating screw rod 3 causes the base 8 threadedly connected to its outer wall to drive the connecting rod 9 and the upper static pressure box 10 to move up or down together. During the downward movement of the upper static pressure box 10, the pressing plate 114 will first contact the workpiece to be measured and be resisted, thereby pressing the first spring 113. The elastic force of the first spring 113 can press and fix the position of the workpiece to be measured to prevent it from moving around. When the upper static pressure box 10 moves downward and presses the workpiece to be measured on the lower static pressure box 2, turn on the pressure blower 14. The pressure blower 14 passes through the pipeline assembly 13 and uses the lower static pressure box 2 and the upper static pressure box 10 to perform conventional comprehensive detection and processing on the workpiece to be measured. When it is necessary to disassemble and assemble the first connecting seat 121 and the second connecting seat 122, rotate the sleeve 128. The sleeve 128 will gradually move upward. When the sleeve 128 moves away from the outside of the stopper 127, the second spring 124 will return to its initial state and push the backing plate 125, the plug 126, and the stopper 127 to move outward together. When the plug 126 completely moves out of the inner cavity of the jack 123, there is no obstruction between the first connecting seat 121 and the second connecting seat 122. At this time, the second connecting seat 122 can be directly disassembled from the first connecting seat 121. When installing them, just insert the second connecting seat 122 into the first connecting seat 121. Rotate the sleeve 128 to make it move downward and resist the stopper 127 to drive the backing plate 125 and the plug 126 to move inward together. When the plug 126 is inserted into the inner cavity of the corresponding jack 123, the first connecting seat 121 and the second connecting seat 122 are clamped and fixed to complete the installation. This device not only optimizes the installation and connection method between the static pressure box and the pipeline assembly, is convenient for disassembly and assembly, simple and convenient to operate, time-saving and labor-saving, but also can press the workpiece to be measured before testing to ensure its position is fixed and prevent movement around from affecting the detection. It is flexible to use, highly practical, and suitable for promotion.
