[0002] The production of railway turnout equipment, such as fixed frog turnouts and movable point frog turnouts, utilizes a large number of automated instruments, including pulse testers, insulation testers, voltage testers, and thermometers. Insulation testers are a common measuring instrument used by electricians to check the insulation resistance of electrical equipment or circuits to ground and between phases to ensure proper operation of these equipment, appliances, and circuits, and to prevent accidents such as electric shock, injuries, and equipment damage. Before taking measurements, disconnect the power supply to the device under test and connect the conductive parts of the device to the ground to ensure sufficient discharge for safety.

[0003] The patent with authorization announcement number CN221224863U discloses an insulation resistance tester with a protective function, including an insulation resistance tester structure and a wire management structure. The wire management structure includes winding columns, elastic members, and extrusion members. The winding columns are symmetrically fixed on both sides of the interior of the box cover. The ends of the winding columns are fixed with limit plates. The elastic members are fixed inside the box cover between the winding columns. The extrusion member is installed on the elastic member. After use, the insulation resistance tester of the utility model can easily organize and store the connecting wires, thereby reducing the trouble caused by loss and facilitating reuse.

[0004] However, the above patent still has the following problems: the above patent requires manual winding of the connecting wire back and forth onto the two winding poles, which is slow and inconvenient for the staff to use. Therefore, a protective device for electrical automation instruments is proposed to address the above problems. Utility Model Content

[0024] Example

[0025] like Figure 1-4As shown, a protective device for an electrical automation instrument comprises a connecting tube 3 and an end cover 4, one end of the connecting tube 3 is fixedly connected to the end cover 4, one end of the end cover 4 is rotatably connected to a retaining ring 15, one end of the retaining ring 15 is fixedly connected to a reel 13, the reel 13 is rotatably connected to the retaining ring 15, one end of the connecting tube 3 is provided with a clamping mechanism, the connecting tube 3 is fixed to the inner side of the box cover 2 on one side of the insulation tester main body 1, and when the reel 13 rotates, the connecting wire will be wound and stored, so that the connecting wire will not be lost, and the connecting wire will not be entangled together, resulting in the phenomenon of damage to the connecting wire due to winding, thereby realizing protection of the connecting wire, and the connecting wire is wound by rotating the reel 13, which improves the winding efficiency and is convenient for the staff to use;

[0026] As a further improvement of the present invention, Figure 1 and Figure 2 As shown, the inner side of the reel 13 is fixedly connected with an anti-slip sleeve 18, and the inner side of the anti-slip sleeve 18 is slidably connected with a lever 16. One end of the lever 16 is fixedly connected with a limit plate 17. The anti-slip sleeve 18 is made of a rubber sleeve. The anti-slip sleeve 18 can increase the friction between the lever 16 and the reel 13, so that the lever 16 and the reel 13 will not slide arbitrarily. When the reel 13 needs to be rotated, the lever 16 is pulled out from the inner side of the reel 13, and then the reel 13 is quickly rotated by the lever 16.

[0027] As a further improvement of the present invention, Figure 1 and Figure 2 As shown, a through slot 14 is provided on the inner side of one end of the reel 13. When the connecting wire needs to be wound up, one end of the connecting wire is first inserted into the inner side of the through slot 14, thereby ensuring that the end of the connecting wire will not move arbitrarily when the reel 13 winds up the connecting wire.

[0028] As a further improvement of the present invention, Figure 2 and Figure 3 As shown, the clamping mechanism includes a guide column 5 that is slidably connected to the connecting tube 3, one end of the guide column 5 is fixedly connected to a cross bar 7, the other end of the cross bar 7 is fixedly connected to a vertical bar 8, the bottom end of the vertical bar 8 is fixedly connected to a clamping shell 9, a card slot 6 is provided on the inner side of one end of the guide column 5, and a clamping assembly is provided at one end of the guide column 5. When the reel 13 is used to reel up the connecting line, the clamping shell 9 is used to clamp and fix the connecting line, thereby preventing the connecting line on the outside of the reel 13 from being scattered during the carrying of the device.

[0029] As a further improvement of the present invention, Figure 2 and Figure 3As shown, the clamping assembly includes a guide shaft 10 that is slidably connected to the connecting tube 3. One end of the guide shaft 10 is fixedly connected to a clamping head 11, and the clamping head 11 is clamped with the guide column 5 through the clamping slot 6. The clamping head 11 can be used to limit and fix the guide column 5 to prevent it from sliding arbitrarily.

[0030] As a further improvement of the present invention, Figure 3 As shown, a spring 12 is provided on the outside of the guide shaft 10, and the two ends of the spring 12 are fixedly connected to the connecting tube 3 and the guide shaft 10 respectively. The spring 12 can give an elastic force to the clamping head 11 through the guide shaft 10 to ensure that the clamping head 11 and the guide column 5 can be stably clamped together.

[0031] Working process: After the insulation tester body 1 is used in the production process of railway turnout equipment, when the connecting wire needs to be stored for protection, one end of the connecting wire is first inserted into the through slot 14, and then the staff pulls out the lever 16 from the inner side of the reel 13, and then the reel 13 is quickly rotated by the lever 16. When the reel 13 rotates, the connecting wire will be wound and stored, so that the connecting wire will not be lost, and the connecting wire will not be entangled together, causing the connecting wire to be damaged due to entanglement, thereby realizing the protection of the connecting wire and passing through the reel 13. The connecting wire is wound up in a rotating manner, which improves the winding efficiency and is convenient for the staff to use. When the reel 13 winds up the connecting wire, the clamping shell 9 clamps and fixes the connecting wire to prevent the connecting wire on the outside of the reel 13 from being scattered during the carrying of the device. When the clamping shell 9 and the connecting wire are clamped together, the spring 12 can give an elastic force to the clamping head 11 through the guide shaft 10, so that the clamping head 11 is stably clamped together with the guide column 5 through the card slot 6, ensuring that the guide column 5 will not move arbitrarily, thereby ensuring the stability of the clamping shell 9 and the connecting wire when clamped.
