Description

Technical Field

[0001] The utility model relates to the technical field of film detection, in particular to a tension detection mechanism which is convenient for fixing a film. Background Art

[0002] Tension testing is the process of measuring and monitoring the tension in an object or system. Tension is the pulling or compressive force on a material or device.

[0003] After searching, the authorization announcement number CN 219455752 U discloses a tension detection mechanism for fixing a film, including a processing table, a fixed frame is fixedly installed on the left end of the upper outer surface of the processing table, a support table is fixedly installed on the right end of the upper outer surface of the processing table, a second constant pressure fixture is fixedly installed on the upper outer surface of the support table, guide rails are fixedly installed on the left and right sides of the upper outer surface of the processing table, a first constant pressure fixture is arranged on the upper part of the guide rail, a tension sensor is fixedly installed on the middle part of the lower outer surface of the first constant pressure fixture, sliders on the left and right sides of the lower outer surface of the first constant pressure fixture, and an electric telescopic rod is fixedly installed on the outer surface of one side of the fixed frame. By setting the first constant pressure fixture and the second constant pressure fixture, it is convenient to test the film with a constant pressure, thereby increasing the accuracy of the experiment.

[0004] In the above technical solution: when the tension of the film is detected, the two ends of the film are fixed. At this time, during the horizontal tensile test, the two ends of the film are easily separated from the clamping mechanism, and the tensile force in the middle part of the film is difficult to accurately detect. The film is fixed on the tension detection mechanism with poor stability, resulting in low detection accuracy.

[0005] To this end, we propose a tension detection mechanism that is convenient for fixing the film. Utility Model Content

By controlling the lifting of the second slide post, the second slide post drives the first slide post to freely lift, and the first slide post drives the clamping gravity block to move up and down. The clamping gravity block moving downward is convenient for clamping and fixing the two ends of the sample film.

[0017] (1) A tension detection mechanism that is convenient for fixing a film. People can conveniently pull the horizontal long plate to slide left and right through the handle groove. When the horizontal long plate slides left and right, the roller will slide along the slope groove as a path.

[0029] Furthermore, a second slide post 11 is slidably mounted on the inverted L-shaped bracket 2, and a connecting piece 12 is fixedly mounted on the upper ends of the first slide post 4 and the second slide post 11. By controlling the lifting and lowering of the second slide post 11, the second slide post 11 drives the first slide post 4 to freely lift and lower, and the first slide post 4 drives the clamping gravity block 5 to move up and down. The clamping gravity block 5 moving downward is convenient for clamping and fixing the two ends of the sample film.

[0030] A horizontal long board 8 is slidably installed between the two groups of inverted L-shaped brackets 2. A slope boss 10 is provided on the horizontal long board 8.

[0034] The lower end of the second slide post 11 is separated from the extrusion pressure caused by the slope boss 10. At this time, the elastic force of the tensioning spring 16 drives the second slide post 11 to slide downward and applies downward pressure to the second slide post 11, so that the second slide post 11 applies pressure downward with the clamping weight block 5 through the first slide post 4. The clamping weight block 5 moving downward clamps and fixes the two ends of the sample film.

[0035] The movable sleeve 15 is rotated to control the upper and lower positions of the movable sleeve 15 , thereby adjusting the tensioning force of the tensioning spring 16 , so that people can adjust the clamping force at both ends of the sample film according to needs.
