The protective cover 13 is made of transparent glass or transparent plastic. A handle 16 is fixed to the front wall of the collection box 15.

[0024] In this embodiment, the mounting plate 2 is used to install the No. 1 cylinder 3. The No. 1 cylinder 3 can drive the slider 5 and the mounting block 6 on the slide rail 4 to move, thereby driving the electronic tensile gauge 7 to move, and realizing the tensile performance test of the rubber seal. The electronic tensile gauge 7 in this embodiment is purchased from the market, and different types of electronic tensile gauges 7 can be selected according to specific needs. The connecting mechanism 9 is used to install the rubber seal to be tested. The No. 2 cylinder 12 is used to drive the lifting of the protective cover 13.

The connection mechanism 9 can install a strip-shaped rubber seal or an annular rubber seal, and the installation is convenient and quick. When the strip-shaped rubber seal needs to be installed, one end of the rubber seal is drawn into the installation groove 92, and then the threaded knob 94 is turned. The threaded knob 94 can drive the clamping plate 93 to move upward, thereby cooperating with the top wall of the installation groove 92 to fix one end of the rubber seal in the installation groove 92. When the annular rubber seal needs to be installed, the rubber seal can be directly hung on the hook 95 on the top of the installation block 91.

[0029] Working principle: When the utility model is used, first install the rubber seal to be tested between the connecting mechanisms 9 on both sides. When a strip-shaped rubber seal needs to be installed, draw one end of the rubber seal into the installation groove 92, and then turn the threaded knob 94. The threaded knob 94 can drive the clamping plate 93 to move upward, thereby cooperating with the top wall of the installation groove 92 to fix one end of the rubber seal in the installation groove 92. When a ring-shaped rubber seal needs to be installed, the rubber seal can be directly hung on the hook 95 on the top of the mounting block 91. After the installation is completed, the No. 2 cylinder 12 is controlled to extend, and the No. 2 cylinder 12 drives the protective cover 13 to move downward until the bottom wall of the protective cover 13 contacts the top wall of the workbench 1, and then the No. 1 cylinder 3 is controlled to contract, and the No. 1 cylinder 3 drives the slider 5 on the slide rail 4 and the mounting block 6 to move, thereby driving the electronic tensile gauge 7 to move, and realizing the tensile performance test of the rubber seal.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. 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.
