[0002] A cable is an electrical energy or signal transmission device consisting of several or several groups of conductors, with an insulating protective layer on the outside, which can transmit electricity or information from one place to another. Cables are widely used and can be seen everywhere in daily life. After the cables are manufactured, they need to be tested to ensure their safety. Therefore, a cable tensile testing device is provided to ensure that the cables can withstand the expected tensile load in various application scenarios, prevent failure phenomena such as breakage and deformation, and thus improve the safety and reliability of the cables.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a cable stretch detection device. Figure 1-4 As shown, it includes a base 1, with mounting plates 2 fixed on both sides of the top of the base 1, an electric telescopic rod 3 installed on the other side of the mounting plate 2, a clamping block 4 is provided on the other side of the electric telescopic rod 3, an electric clamping head 5 is installed inside the clamping block 4, protective structures 6 are provided at both ends of the top of the base 1, and a limiting structure 7 is provided at the top of the base 1.

[0023] It should be noted that, due to the problem of the cable collapsing when stretched and posing a danger to the workers, this solution sets up a protective structure 6, and the limit blocks 603 are evenly fixed on both sides of the top of the base 1. Through the locking structure of the protective frame 601 and the limit block 603, the bottom ends of the two sets of protective frames 601 can be correspondingly locked inside the limit block 603. The first bolts 604 are symmetrically distributed inside one end of the limit block 603, and the protective frame 601 inside the limit block 603 is limited and fixed, making the installation and disassembly of the protective frame 601 more convenient. The transparent plate 602 is used for easy observation and has a protective effect to avoid the cable collapsing when stretched and causing harm to the workers.

[0024] Specifically, in this embodiment, this scheme mainly includes a protective structure 6, which includes a limit block 603. The limit block 603 is fixed to the top of the base 1. A protective frame 601 is provided inside the limit block 603. A transparent plate 602 is provided inside the protective frame 601. A first bolt 604 is provided inside one end of the limit block 603. First, the limit block 603 is evenly fixed to the top of the base 1, and then the transparent plate 602 is limited and fixed inside the protective frame 601. Then, the bottom ends of the two groups of protective frames 601 are evenly engaged with the inside of the limit block 603, so that the two groups of transparent plates 602 are symmetrically limited at the top of the base 1. Then, the first bolt 604 is symmetrically screwed through the limit block 603 to limit the protective frame 601 inside the limit block 603, so that the protective frame 601 and the transparent plate 602 protect the cable tensile detection device to prevent unqualified cables from breaking when stretched and causing harm to the staff.

[0025] In a further preferred embodiment of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, there are four groups of limit blocks 603, and the four groups of limit blocks 603 are evenly distributed at the top of the base 1. The outer diameter of the protective frame 601 is smaller than the inner diameter of the limit blocks 603. The protective frame 601 and the limit blocks 603 form a snap-fit ​​structure. Through the uniform distribution of the limit blocks 603, the two groups of protective frames 601 can be limited. The snap-fit ​​structure of the protective frame 601 and the limit blocks 603 enables the transparent plate 602 to be symmetrically snapped on the top of the base 1, and at the same time facilitates the disassembly of the protective frame 601.

[0026] Specifically, in this embodiment, this solution mainly includes a limiting structure 7, which includes a locking groove 706. The locking groove 706 is arranged inside the other side of the base 1. The locking groove 706 is provided with a locking block 704. The locking block 704 is provided with a second bolt 705. The other side of the locking block 704 is fixed with a limiting plate 701. The limiting plate 701 is provided with a sliding groove 703 inside. The sliding groove 703 is provided with a connecting block 702 inside. First, the sliding groove 703 is opened inside the limiting plate 701, and then the connecting block 702 is limited to the inside of the sliding groove 703. Then, the inside of the mounting plate 2 is fixed with the locking block 704. A locking groove 706 is opened, and the locking block 704 is fixed on one side of the limit plate 701. The locking block 704 is then locked inside the locking groove 706, so that the limit plate 701 can be initially limited at the top of the base 1. The second bolt 705 is then screwed through the locking block 704 to limit and fix the limit plate 701, and then the connecting block 702 is fixed to the top and bottom ends of the clamping block 4 accordingly, so that the clamping block 4 can slide inside the slide groove 703 when moving, limiting the movement of the clamping block 4, making the movement of the clamping block 4 more stable, and the cable tensile test more stable.

[0027] In a further preferred embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the outer diameter of the connecting block 702 is smaller than the inner diameter of the slide groove 703, the connecting block 702 and the slide groove 703 constitute a sliding structure, the outer diameter of the locking block 704 is smaller than the inner diameter of the locking groove 706, the locking block 704 and the locking groove 706 constitute a locking structure, through the sliding structure of the connecting block 702 and the slide groove 703, the connecting block 702 moves inside the slide groove 703, and the movement of the clamping block 4 is limited. The locking structure of the locking block 704 and the locking groove 706 facilitates the limiting and fixing of the limiting plate 701, making the limiting of the limiting plate 701 more stable.
