Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1, by Figure 1 The present invention relates to a tensile testing device for signal line quality testing, comprising a base 1, and a fixing mechanism 2 provided on the top of the base 1.

[0026] Specifically, by Figure 2-5The fixing mechanism 2 includes an outer U-shaped rod 201 located above the base 1. A left base plate 206 and a right base plate 2011 are fixedly connected to both ends of the outer U-shaped rod 201. The left base plate 206 and the right base plate 2011 are provided with a movable plate 208 and a fixed plate 2010. The fixed plate 2010 is located between the movable plate 208 and the right base plate 2011. The fixed plate 2010 is fixed to the top of the base 1, and the movable plate 208 is movably installed on the top of the base 1. The tops of both the movable plate 208 and the fixed plate 2010 are fixed... A fixed U-shaped rod 2013 is connected to the outer side of each of the two U-shaped rods 2013. A left lifting plate 207 and a right lifting plate 2012 are movably sleeved on the outer sides of the rods 2013, respectively. The left lifting plate 207 and the right lifting plate 2012 are located directly above the movable plate 208 and the fixed plate 2010, respectively. A left arc-shaped block 2014 is fixedly connected to the side of the right lifting plate 2012 and the fixed plate 2010 that are close to each other. A right arc-shaped block 2015 is fixedly connected to the side of the movable plate 208 and the left lifting plate 207 that are close to each other. The left lifting plate 207... A top ring 2016 is fixedly connected to the top of the structure. A lifting frame 204 is movably sleeved on the outer side of the outer U-shaped rod 201. A horizontal column 205 is fixedly connected to the inner side of the lifting frame 204. A right lifting plate 2012 is fixedly sleeved on the outer side of the horizontal column 205. The top ring 2016 is movably sleeved on the outer side of the horizontal column 205. The left arc-shaped block 2014 and the right arc-shaped block 2015 are the same in shape and size. The top surfaces of the fixed plate 2010 and the movable plate 208 are flush. The bottom surfaces of the right lifting plate 2012 and the left lifting plate 207 are flush. The top ring 2016 is fixedly connected to the top of the structure. The inner side of 016 is provided with an annular groove 2018, and multiple balls 2017 that fit against the outer wall of the horizontal column 205 are evenly arranged in the annular groove 2018. By setting the balls 2017, the top ring 2016 is prevented from directly contacting the horizontal column 205, reducing the friction between the top ring 2016 and the horizontal column 205, and facilitating the sliding of the top ring 2016 on the outside of the horizontal column 205. A sleeve block 203 is fixedly sleeved on the middle of the outer side of the outer U-shaped rod 201.

[0027] In use, first place both ends of the signal cable on the lower left arc-shaped block 2014 and right arc-shaped block 2015 respectively. Then, activate the downward pressing cylinder 202 to drive the lifting frame 204 to slide down along the outer U-shaped rod 201 and drive the horizontal column 205 to descend. Through the top ring 2016, drive the left lifting plate 207 to slide down along the corresponding inner U-shaped rod 2013, and at the same time drive the right lifting plate 2012 to slide down along the corresponding inner U-shaped rod 2013. This will also drive the upper left arc-shaped block 2014 and right arc-shaped block 2015 to move down, clamping both ends of the signal cable at the same time, and finally achieving quick fixation of the signal cable.

[0028] Specifically, by Figure 6As shown, a guide post 209 is fixedly connected between the left base plate 206 and the right base plate 2011. A movable plate 208 is movably sleeved on the outside of the guide post 209. A fixed plate 2010 is fixedly sleeved on the outside of the guide post 209.

A pulling cylinder 2020 is fixedly installed between the tension sensor 2019 and the left base plate 206.

[0029] In use, the pull cylinder 2020 is first activated, and the tension sensor 2019 drives the movable plate 208 to slide along the guide post 209, so that the movable plate 208 moves away from the fixed plate 2010 and tightens the signal line. The tension sensor 2019 displays the tension value, and finally the tension test of the signal line is achieved.
