[0002] A tensile testing machine, also known as a tensile testing machine, is a mechanical force testing machine used to perform mechanical property tests such as stretching, compression, bending, shearing, and peeling on metal and non-metallic materials. It can perform tensile testing on items within wires to determine the maximum tensile force the wires can withstand. The testing process involves clamping both ends of the wire on two fixtures spaced a certain distance apart. The two fixtures separate at a certain speed, stretching the sample, and measuring the stress changes on the sample until the wire breaks.

[0003] After searching, the patent with announcement number CN215296956U discloses a protective device for a tensile testing machine used in HDMI cable production.

A T-shaped slider is slidably connected to the inside of the T-shaped slot, a connecting baffle is mounted on the top of the T-shaped slider, and an L-shaped protective plate is mounted on the top of the front of the connecting baffle. The utility model provides an L-shaped protective plate, a connecting baffle, and a limit rod. The cooperation between the L-shaped protective plate and the connecting baffle can prevent the operator from being injured by flying fragments when the HDMI cable breaks, thereby protecting the operator and increasing the safety of the device during operation.

[0008] A protective mechanism is provided on the bottom plate to shield and protect the waste generated by the line test;

[0009] The cleaning mechanism is arranged on the protective mechanism and is used for cleaning the protective mechanism.

[0010] In a possible design, the protective mechanism includes a protective cover, a top plate, two electric telescopic rods, a baffle, and transparent glass. The front side and bottom of the protective cover are set as open areas. The protective cover is set on the bottom plate. The fixed ends of the two electric telescopic rods are respectively fixedly connected to the tops of the two side blocks, and the telescopic ends of the two electric telescopic rods are respectively fixedly connected to the two sides of the bottom of the same top plate. The bottom of the top plate is fixedly connected to the bottom of the baffle.

A rectangular hole is opened on the baffle. The transparent glass is fixedly set on the inner wall of the rectangular hole. A controller is provided on one side of the protective cover.

[0011] In one possible design, the cleaning mechanism includes a connecting strip, two wiping cottons, two triangular blocks and an L-shaped plate. The top rear side of the L-shaped plate is fixedly connected to the front side of the protective cover by bolts. The two triangular blocks are provided with empty slots for convenient bolt connection. The bottom two sides of the connecting strip are respectively fixedly connected to the two triangular blocks by bolts. The sides of the two triangular blocks that are far away from each other are respectively fixedly connected to the inner walls of the two sides of the same protective cover by bolts. The front side of the connecting strip and the bottom rear side of the L-shaped plate are respectively fixedly connected to one side of the two wiping cottons, and the sides of the two wiping cottons that are close to each other are respectively attached to the front and rear sides of the same baffle.

[0012] In one possible design, a front plate is fixedly provided on the top of the bottom plate, a top groove is opened on the top of the front plate to facilitate fitting with and stabilizing the baffle, and a bottom strip that fits with the top groove is fixedly connected to the bottom of the baffle.

[0013] In a possible design, sliding bars are fixedly connected to both sides of the baffle, and sliding grooves that fit with the sliding bars are opened on the inner walls of both sides of the protective cover, and the two sliding bars are slidably connected to the two sliding grooves respectively.

During the test, any waste or debris that may be generated will be effectively blocked by the protective cover to prevent it from splashing outside the test area. The front and bottom of the protective cover are designed to be open to facilitate the entry and exit of the HDMI cable. At the same time, the baffle connected to the top plate through the electric telescopic rod can be adjusted in height as needed, which is convenient for replacing the cable and also convenient for blocking waste during testing. The transparent glass on the baffle allows the operator to test without opening the protective cover. When observing the test process under normal circumstances, a certain amount of waste debris will accumulate after the test is completed or in the protective cover, and then stain the transparent glass, affecting the inspection personnel's observation of the interior. When the electric telescopic rod is controlled by the controller to drive the top plate and baffle to move up and down, during the movement of the baffle, the two wiping cottons are respectively close to the front and back sides of the baffle, automatically removing the waste debris attached to the baffle and the transparent glass, ensuring that the observation window is clean and tidy, which is convenient for observing the interior. The design of the wiping cotton eliminates the need for manual intervention in the cleaning process, thereby improving the cleaning efficiency and convenience. The mounting plates and mounting holes on both sides of the bottom plate are designed so that the entire device can be conveniently fixed on the test bench or other work platform, reducing the movement of the device during the inspection process and facilitating use and maintenance.
