[0037] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0038] Please refer to Figure 1 、 Figure 2 The present application provides a movable temperature rise test connection sorting device. As a specific embodiment, the sorting device includes: a box body 1, an installation space is formed inside, and a roller 7 is provided at the bottom; the box body 1 can be pushed to move by setting the roller 7; a cable drum 2, including a plurality of cable drums 2 arranged inside the installation space; a soft connection 4, which is wound and stored and arranged on the periphery of the cable drum 2; a plurality of openings 10 are provided on the side wall of the box body 1, which are arranged one by one corresponding to the plurality of cable drums 2, and the end of the soft connection 4 can extend from the opening 10.

[0039] Specifically, it should be noted that the flexible connection is a wire used to connect the experimental equipment and the tested equipment. The tested equipment of different models and powers have different power-carrying currents, and different flexible connections are required for testing. The present application sets up multiple cable drums 2, and the flexible connection 4 is wound on the cable drum 2 through the cable drum 2, so as to achieve the purpose of classifying and storing flexible connections of different models, thereby achieving the purpose of storing the flexible connections. When storing, the middle position of the flexible connection is fixed on the surface of the cable drum 2, and then the cable is wound on the cable drum 2 by rotating the cable drum 2, and then both ends of the flexible connection are extended out of the box 1 from the opening 10. When in use, the two ends of the flexible connection are pulled out, and then one end of the flexible connection is connected to the electrical equipment and the other end is connected to the detection equipment, so as to test the electrical equipment. After the test is completed, the flexible connection is stored on the cable drum 2 again.

[0040] Furthermore, the roller 7 is an arc-extinguishing universal wheel.

[0041] Further, as a specific embodiment, refer to Figure 2 , along the horizontal direction, a plurality of mounting brackets 3 are arranged at intervals in the installation space, the mounting bracket 3 includes two mounting members arranged in parallel and at intervals, the mounting members are arranged vertically, and the two ends of the cable drum 2 are rotatably connected to the two mounting members respectively.

[0042] Specifically, the specific structure of the cable drum 2 includes a cylinder and a rotating shaft arranged at both ends of the cylinder. As a specific implementation method, the mounting member can be a plate body, and a through hole is provided on the plate body for rotating cooperation with the rotating shaft. The rotating shaft is rotatably connected to the mounting member through the through hole. By providing a mounting frame 3, the cable drum 2 can be vertically spaced on the mounting frame 3, so that multiple cable drums can be evenly and reasonably arranged inside the box 1, thereby effectively utilizing the installation space inside the box. As a specific implementation method, the size of the cabinet in this application is 1500mm*height 1300mm*depth 1600mm, and both ends of the mounting member are welded in the cabinet. The mounting frame 3 includes six groups, and each group of mounting frames is provided with three cable drums from top to bottom. The middle position of the soft connection is fixed to the outer peripheral surface of the cable drum 2 by bonding or the like.

[0043] Furthermore, as a specific embodiment, a spiral spring (not shown in the figure) is provided between the cable drum 2 and at least one mounting member.

[0044] Specifically, the cable drum is rotatably connected to the mounting member via a rotating shaft, and a spiral spring (not shown in the figure) is arranged between the mounting member and the rotating shaft, so that the rotating shaft can rotate the cable drum 2 under the elastic force of the spiral spring (not shown in the figure). When the flexible connection is stored, the flexible connection is first wound around the cable drum 2, and the end of the flexible connection is extended from the opening 10. When the flexible connection is used, the flexible connection is pulled out for use by pulling the end of the flexible connection to resist the spiral spring (not shown in the figure) to pull the cable drum to rotate. After use, the cable drum can be driven to rotate by the elastic force of the spiral spring (not shown in the figure) to store the flexible connection on the cable drum, thereby achieving the purpose of automatically storing the flexible connection. In this field, the connection method of driving the rotating shaft to return by the elastic force of the spiral spring (not shown in the figure) is a commonly used technical means, and its specific connection structure will not be described here one by one.

[0045] Furthermore, a copper busbar placement box 5 is provided on the side wall of the box body 1 .

[0046] Specifically, when conducting a test, copper busbars are required to connect the device being tested and the flexible connection, and between the test device and the flexible connection. By providing a copper busbar placement box 5 on the outer wall of the box body 1, the copper busbars can be stored and accommodated for easy access.

[0047] Furthermore, as a preferred embodiment, the opening 10 is provided with a rotatable elbow 6 , one end of the rotatable elbow 6 is connected to the outer side wall of the box, and the end of the soft connection 4 can extend from the inside of the rotatable elbow 6 .

[0048] Specifically, since the opening is directly cut on the side wall of the box body 1, the box body is made of a steel plate with a thickness of 0.2mm-1.5mm. When the soft connection is pulled out of the opening 10 and recovered, the soft connection droops on the lower side of the opening under the action of gravity. The outer surface of the soft connection inevitably contacts and rubs against the side of the opening 10, which can easily cut the soft connection and cause the position where the soft connection contacts the lower side of the opening to be excessively bent, affecting the service life of the soft connection. By arranging a rotating elbow at the opening, the rotating elbow provides support for the soft connection, avoiding contact between the soft connection and the lower side of the opening, thereby effectively protecting the soft connection.

[0049] Further, as a specific embodiment, refer to Figure 3-Figure 11 The specific structure of the soft connection is: the rotatable elbow 6 includes a first end 61 connected to the box body, a second end 62 rotatably connected to the other end of the first end 61, and a protective gasket 66 is provided at one end of the second end 62 away from the first end.

[0050] Specifically, refer to Figure 3-Figure 6 、 Figure 9 、 Figure 11 The first end 61 is a U-shaped groove structure, with a U-shaped buckle plate 69 on the top to form a rectangular channel, and a rectangular channel is also formed inside the second end, and the first end and the second end are rotatably connected. When in use, the first end is fixed to the box body by welding, screwing, etc., and the first end is kept horizontally set, wherein the opening 10 is a rectangular opening, and the size of the rectangular channel cross section inside the first end is consistent with the size of the opening 10. When the first end is installed on the box body, the rectangular channel is compared with the opening 10, and the second end can be rotated up and down. Through this design In the configuration mode, when in use, the soft connection extends from the inside of the first end and the second end. At this time, the second end is rotated to a suitable angle to ensure that the angle between the second end and the first end is an obtuse angle, so that the first end and the second end of the rotatable elbow 6 can jointly support the soft connection 4 to avoid scratching with the side of the opening 10 and excessive bending of the soft connection. By arranging a protective gasket 66 at the end of the second end, the protective gasket is made of rubber, which can reduce the probability of the soft connection and the mouth of the second end being scratched, thereby effectively protecting the soft connection and increasing the service life of the soft connection.

[0051] Further, as a specific embodiment, the connection method of the first end head and the second end head is: one of the first end head and the second end head is provided with a first connecting plate 63, and the other is provided with a second connecting plate 64 that rotates with the first connecting plate 63, the first connecting plate is provided with a first rotating part 65, the second connecting plate 64 is provided with a through hole 641 that cooperates with the first rotating part, one of the first connecting plate and the second connecting plate is provided with a plurality of grooves 632 around the first rotating part 65, and the other is provided with an elastic telescopic column 67.

[0052] Specific, exemplary, reference Figure 3-Figure 11 The first connecting plate is arranged on the first end 61, and the second connecting plate is arranged on the second end. The first connecting plate and the second connecting plate are rotatably connected by the first rotating part 65, and a plurality of grooves 632 are provided on a surface of the first connecting plate close to the second connecting plate. The plurality of grooves are evenly spaced along a circular trajectory coaxial with the first rotating part. An elastic telescopic column 67 is provided on the second connecting plate. When the elastic telescopic column coincides with the groove, it can penetrate into the groove under the action of elasticity, thereby forming a rotation resistance between the first connecting plate and the second connecting plate. Through this setting method, when using the soft connection, the second end is adjusted to a suitable posture before rotating. The current posture is maintained under the action of dynamic resistance, the flexible connection is supported, and the posture of the second end can be adjusted by applying a force greater than the rotational resistance to the second end. At the end of the experiment, the cable drum 2 wraps the flexible connection for storage, and the end of the flexible connection 4 is bent upward and hooked above the protective gasket 66, and then the end of the flexible connection is fixed by wrapping the rubber ring around the outside of the protective gasket. Then the second end is rotated upward to make the second end vertical or at an acute angle to the first end to block the opening. The end of the flexible connection can also be located on the side of the second end close to the box, thereby effectively protecting the end of the flexible connection.

[0053] Furthermore, as a specific embodiment, the first connecting plate 63 includes two parallel and spaced apart plates, one of the first end and the second end is integrally provided with the first connecting plate 63 , and the other is detachably connected to the second connecting plate 64 .

[0054] Specifically, refer to Figure 3-Figure 5 , a first connecting plate is provided on both sides of the first end 61, and a second threaded hole 621 is provided on both sides of the second end. Figure 7 The second connecting plate includes three through holes 642 corresponding to the three second threaded holes. The second connecting plate is connected to the second end through a locking stud 643. The connection stability can be improved by rotating the two first connecting plates and the two second connecting plates.

[0055] Further, as a specific embodiment, refer to Figure 4 、 Figure 5 、 Figure 7 The first rotating part 65 includes a cylindrical protrusion 651 arranged on the opposite side of the two first connecting plates, a threaded hole 652 coaxially arranged on the end face of the protrusion 651 and a limiting nut 653 threadedly connected to the threaded hole 652.

[0056] Specifically, refer to Figure 7 The second connecting plate is sleeved on the protrusion 651 through the through hole 641, and then the limiting nut 653 is threadedly connected in the threaded hole 652. The second connecting plate is limited by the limiting nut 653, so that the second connecting plate forms a rotational fit with the first connecting plate, and then the second connecting plate is installed on the second end head. This method facilitates the installation of the first end head and the second end head.

[0057] Furthermore, the elastic telescopic column 67 includes a guide hole 671 passing through the second connecting plate 64, a guide column 672 arranged at the end of the guide hole 671, a limiting surface 673 arranged at the other end of the guide hole, and a compression spring 674 arranged between the limiting surface 673 and the guide column 672.

[0058] Specifically, the elastic telescopic column includes two symmetrically arranged about the through hole 641, so as to obtain better limiting friction. As a specific implementation method, the specific structure of the elastic telescopic column is as follows: Figure 10 The second connecting plate includes a guide hole set through it, and the end of the guide hole away from the first connecting plate is threadedly connected to an end cover 6731. The limiting surface 673 is the end surface of the end cover. A guide column 672 is set in the guide hole for guidance. The end of the guide column is hemispherical, and the elastic force of the compression spring 674 can make the guide column rest against the first connecting plate.

[0059] Further, as a specific embodiment, refer to Figure 11 A flexible dustproof layer 68 is provided at the connection between the first end and the second end. The two ends of the dustproof layer 68 are respectively connected to the first end and the second end, so as to achieve a dustproof effect. The dustproof layer can be made of materials such as rubber and cloth. As a specific embodiment, refer to Figure 1 , each opening 10 on the box body is provided with a soft connection specification mark 8, which marks the specifications of the soft connection 4, making it easier to use.
