[0021] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.
[0022] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.
[0023] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).
[0024] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).
[0025] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.
[0026] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.
[0027] Beneficial effects of the utility model:
[0028] When the utility model is used, after the film passes through the gap between the fixed end film pressing plate and the cross bar, the synchronous cylinder is adjusted to press the front end of the film, and the film passes through the two chrome-plated steel pipes at the upper end of the aluminum profile bracket, and naturally droops at the outer circle tangent point of the rear end chrome-plated steel pipe. After passing through the center of the movable end film pressing plate, the screws at both ends are manually tightened to press the film. After the fixing pin is pulled out, the movable end film pressing plate naturally droops. At this time, the position of the depth micrometer is adjusted to record the data of different positions of the film, and the droop degree of the film is calculated by the difference in the recorded data. The utility model has a simple and reliable structure, is easy to operate, and can effectively and quickly perform droop tests on the film, thereby better improving the quality of the film product.
