DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-4 As shown, a new energy cable stretching detection device proposed by the utility model includes: a detection box 1, in which a detection slot 14 and an equipment slot 15 for cable stretching detection are provided; a detection mechanism 4, which is arranged in the detection slot 14 and the equipment slot 15; a motor 3, which is installed on one side of the detection box 1, and the output shaft is connected to the detection mechanism 4.

[0023] In this embodiment, the detection mechanism 4 includes a rotating rod 5, one end of which is fixedly connected to the end of the output shaft of the motor 3, and the other end is rotatably connected to the inner wall of the equipment groove 15. A plurality of threaded areas 10 are provided on the rotating rod 5, and the threaded area 10 is composed of two opposite threaded grooves. The two opposite threaded grooves on the threaded area 10 are both threadedly connected to two matching threaded rings 6. The threaded ring 6 is provided with an annular limiting groove 19, and a rotating block 18 is slidably connected to the annular limiting groove 19. Two adjacent rotating blocks 18 located at the same threaded area 10 are connected to the rotating block 18. The movable blocks 18 are rotatably connected with connecting blocks 7, and the ends of the two connecting blocks 7 away from the threaded ring 6 are rotatably connected with telescopic rods 8. The ends of the telescopic rods 8 away from the connecting blocks 7 penetrate the detection box 1 and extend into the detection groove 14. The ends of the multiple telescopic rods 8 located in the detection groove 14 are fixedly connected with grab hooks 9. The inner walls at both ends of the detection groove 14 are provided with through holes for facilitating the passage of cables. The tops of both sides of the detection box 1 are penetrated with first threaded shafts 13, which are threadedly connected to the detection box 1, and the bottom ends extend to the detection box 1. The cable is passed through the two through holes in sequence, and then the two first threaded shafts 13 are used to abut and limit the two ends of the cable. According to the detection requirements, the middle part of the cable is controlled to be in an appropriate bending or straightening state to facilitate subsequent stretching. When performing a stretching test, the motor 3 is turned on so that the output shaft of the motor 3 drives the rotating rod 5 to rotate. Subsequently, under the setting of multiple threaded areas 10, the two threaded rings 6 follow the rotation direction of the rotating rod 5 to move relative to or away from each other, thereby driving the corresponding two connecting blocks 7 to expand or retract, and finally causing the corresponding telescopic rod 8 to reciprocate in the detection box 1. At this time, in the detection slot 14, the grab hook 9 on the telescopic rod 8 will hook different parts of the cable for reciprocating stretching. The above setting can effectively avoid inaccurate detection results caused by a single direction when the cable is stretched. By performing synchronous zone stretching at different positions of the cable, the results of the cable stretching test are greatly improved.

[0024] Furthermore, a plurality of limit shafts 11 are fixedly connected to the bottom of the inner wall of the detection groove 14, and an array of the plurality of limit shafts 11 is distributed between the plurality of grab hooks 9. Through the cooperation of the plurality of limit shafts 11 and the plurality of grab hooks 9, different positions of the cable can be stretched in zones to a greater extent. When the user changes the spacing between the limit shafts 11, the zone size during the cable stretching detection can be changed.

[0025] Furthermore, the top ends of two adjacent limit shafts 11 are connected with limit blocks 12, and the outer surfaces of the multiple limit shafts 11 are all provided with smooth stainless steel rings. Through the above settings, the friction between the cable and the limit shafts 11 during stretching can be reduced, and the damage to the surface of the cable can be reduced. The setting of the limit block 12 can prevent the cable from suddenly detaching from the two limit shafts 11 and causing external safety hazards. At the same time, the cable can be stabilized between the two limit shafts 11 to stably perform stretching detection.

[0026] Among them, a retaining ring 17 is arranged between two adjacent threaded areas 10, and the retaining ring 17 is sleeved and fixed on the rotating rod 5. By arranging the retaining ring 17 between the two threaded areas 10, it is possible to prevent the bracket of the threaded ring 6 from colliding with another threaded ring 6 in another threaded area 10 in order to increase the failure loss. After the retaining ring 17 is arranged, even if a failure occurs, the number and cost of damaged parts after the failure can be reduced, thereby enhancing the safety of the device.

[0027] In addition, a through threaded hole is opened on the side of the grab hook 9 opposite to the telescopic rod 8, and the second threaded shaft 16 is threadedly connected in the threaded hole. By arranging the second threaded shaft 16 on the grab hook 9, one end of the second threaded shaft 16 will abut against the surface of the cable when the second threaded shaft 16 is rotated, and the surface of the cable will be gradually squeezed and limited as it rotates.

[0028] The working principle of this embodiment is as follows: the cable is passed through the two through holes in sequence, and then the two ends of the cable are abutted and limited by the two first threaded shafts 13. At the same time, the cable should pass through multiple limit shafts 11. By cooperating with multiple grab hooks 9, the different positions of the cable can be stretched to a greater extent. When the user changes the spacing between the limit shafts 11, the partition size during the cable stretching test can be changed. According to the test requirements, the middle part of the cable is controlled to be in an appropriate bending or straightening state to facilitate subsequent stretching. When performing the stretching test, the motor 3 is turned on so that the output shaft of the motor 3 drives the rotating rod 5 to rotate. Then, under the setting of multiple threaded areas 10, the two threaded rings 6 follow the rotation direction of the rotating rod 5 to move relative to or away from each other, thereby driving the corresponding two connecting blocks 7 to expand or retract, and finally making the corresponding telescopic rod 8 reciprocate through the detection box 1. At this time, in the detection groove 14, the grab hook 9 on the telescopic rod 8 will hook different parts of the cable for reciprocating stretching. The above setting can effectively avoid inaccurate detection results caused by a single direction when the cable is stretched. By performing synchronous zone stretching on different positions of the cable, the result of cable stretching detection is greatly improved.

[0029] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
