Detailed implementation manners

[0024] The following will describe the detailed implementation manners of the present disclosure in conjunction with the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for the purpose of illustration and explanation of the present disclosure, and are not used to limit the present disclosure.

[0025] In the present disclosure, unless otherwise stated, the orientation terms such as "inner" and "outer" generally refer to the inside and outside of the actual contour of the relevant components during use. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance.

[0026] An embodiment of the present disclosure provides a storage device for test wires, including a first frame 10, a second frame 50, a drum 40, and a third frame 11. As Figures 1 to 3 shown, a first joint 14 may be provided at the edge of the first frame 10, which can be snap - connected to a second joint 53 provided at the edge of the second frame 50. Corresponding first groove 13 and second groove 52 are respectively provided at the centers of the first frame 10 and the second frame 50. Both ends of the drum 40 can be rotatably provided in the first groove 13 and the second groove 52 respectively for winding the test wires. At the same time, the third frame 11 can be fixedly provided on the side of the first frame 10 away from the second frame 50. The positional relationship between the third frame 11 and the first frame 10 can be referred to Figure 3 ., and a motor 20 is accommodated inside it. A first through - hole 12 is provided at the center of the first frame 10, and the transmission shaft 21 of the motor 20 can be coaxially connected to the drum 40 through the first through - hole 12 to rotate under the drive of the motor 20 and the transmission shaft 21.

[0027] Through the above technical solutions, the storage device is composed of two snap - connectable frames and a drum 40. The drum 40 is driven by a motor 20 to rotate for winding the test wires, so as to realize the automatic storage of the test wires. This storage device is simple to assemble, convenient to store, easy to use, and can free both hands. The storage of the test wires is also more regular, improving the storage efficiency and avoiding the chaos caused by the entanglement of the test wires during use.

[0028] In some embodiments, as Figure 1As shown, a second through hole 51 corresponding to the first through hole 12 may be provided at the center of the second frame 50. The drum 40 is arranged as a hollow cylinder with one end open, and the open end of the drum 40 may communicate with the second through hole 51. Among them, a wire groove 41 is circumferentially formed on the circumferential surface of the drum 40 near the open end, and a test wire can be threaded through the second through hole 51. Through this embodiment, the test wire can extend from the outside into the inside of the drum 40 through the second through hole 51, then pass through the wire groove 41, and be attached to the circumferential surface of the drum 40 to realize the winding of the test wire when the drum 40 rotates.

[0029] Exemplarily, the wire groove 41 may include a plurality of circular card slots arranged side by side and having the same shape, such as Figure 1 and 2 As shown, each circular card slot can be used to clamp a strand of test wire, so as to facilitate fixing different strands of test wires in the plurality of circular card slots of the wire groove 41 respectively, thereby realizing the classified winding of the test wires, improving the storage efficiency of multiple strands of wires, effectively avoiding entanglement and knotting between multiple strands of test wires, and making it more convenient to extract the stored test wires during use.

[0030] In some embodiments, such as Figure 1 and Figure 2 As shown, the number of circular card slots can be four. When detecting relay protection lines, the conventional configuration of test wires needs to include different specifications of wire types classified by different colors for detecting and troubleshooting different fault conditions, and the number of such wire types is usually four. In this embodiment, when the number of circular card slots is four, it can be applicable to the classified storage of four test wire types in the conventional configuration. It should be noted that the present disclosure does not specifically limit the number of circular card slots. Among them, the four circular card slots only provide a relatively common number setting, which is used to match the four test wire types. This number is not special. If the number of wire type specifications of the test wires in the matching test equipment changes, the number of circular card slots in this embodiment should also change accordingly and need to be the same as the number of test wire types. The specific number setting should be adaptively adjusted according to the actual number of test wire types to be matched, which will not be elaborated here.

[0031] Exemplarily, such as Figure 1 As shown, the diameter of the second through hole 51 can be equal to the inner diameter of the drum 40, avoiding the formation of an obvious stepped edge between the two due to the different diameters of the inner diameter of the drum 40 and the second through hole 51, which may cause wear to the skin of the test wire.

[0032] According to some embodiments, such as Figure 4As shown, the first joint portion 14 may include a third groove 15 and a third through hole 16 located on the third groove 15. Meanwhile, the second joint portion 53 may further include a plug-in member for inserting into the third groove 15 and a bump formed on the plug-in member, so that when the plug-in member is inserted into the third groove 15, the bump can be engaged with the third through hole 16, thereby fixedly connecting the first frame 10 and the second frame 50 to form the housing of the storage device.

[0033] In some embodiments, as Figure 4 shown, the plug-in member may include a first rod 54 and a second rod 55 arranged at intervals. Wherein, the first rod 54 and the second rod 55 may respectively fit on both sides of the inner walls of the third groove 15 opposite to each other. In this embodiment, the first rod 54 relatively fits on the side wall of the third groove 15 close to the inside of the roller 40, and the second rod 55 relatively fits on the side wall of the third groove 15 far from the outside of the roller 40. And when the first rod 54 is closer to the inside of the storage device than the second rod 55, it can be used for the overall positioning and guiding of the plug-in member, so as to facilitate the insertion of the plug-in member between the inner wall of the third groove and the third groove 15.

[0034] Exemplarily, as Figure 4 shown, the first rod 54 and the second rod 55 may be configured to generate elastic deformations towards each other when being squeezed. This elastic deformation occurs at the roots where the first rod 54 and the second rod 55 are respectively connected to the second joint portion 53. When they are under the pressure in the radial direction of the third groove 15, they can generate deformations towards each other, thereby shortening the distance between the first rod 54 and the second rod 55. Meanwhile, when the distance between the first rod 54 and the second rod 55 becomes smaller, the outer diameter of the overall contour of the plug-in member is smaller than the inner diameter of the third groove 15, allowing the plug-in member to be inserted into the inside of the third groove 15. And when the bump is inserted into the third through hole 16, the distance between the first rod 54 and the second rod 55 resumes to the initial size to be clamped in the third groove 15.

[0035] According to some embodiments, as Figure 4 shown, the bump may be configured to protrude out of the outside of the second frame 50 after being inserted into the third through hole 16. In this embodiment, the width of the bump in the third groove 15 should be greater than the side wall width of the third through hole 16, so that the bump can partially protrude to the outside of the second frame 50 after being inserted into the third through hole 16. So that when the first frame 10 and the second frame 50 are buckled, the operator can press the part of the bump protruding out of the outside of the second frame 50 to cause the second rod 55 to deform and shorten the distance between the first rod 54 and the second rod 55, so as to pull the plug-in member out of the third groove 15, thereby realizing the separation operation of the first frame 10 and the second frame 50 in the combined state, which is beneficial to the maintenance of the inside of the storage device or the replacement of the test line.

[0036] Exemplarily, as Figure 4As shown, one side of the boss can be an inclined guiding slope, which can form an acute angle at the connection between the projection and the first rod 54, so that the plug-in can smoothly slide into the third groove 15 when inserted into the third groove 15. At the same time, the guiding slope can cooperate with the inclined hole wall of the third through hole 16, so that when the part of the projection protruding outside the second frame 50 is pressed, the projection can smoothly slide away from the third through hole 16, which is conducive to the disassembly and separation of the plug-in from the third groove 15. It should be noted that the other side of the projection opposite to the guiding slope should be designed to be an edge shape that will not easily separate from the hole wall of the third through hole 16 after the projection is inserted into the third through hole 16. For example, the side can be designed to form a right angle with the connection of the first rod 54 to ensure that after the projection is inserted into the third through hole 16, the side can be clamped on the hole wall of the third through hole 16 to prevent the first rod 54 from naturally separating from the third groove 15 without external force extrusion. In the embodiment of the present disclosure, the side of the protrusion may also be designed in other shapes, and there is no specific limitation on this. It only needs to ensure that the protrusion facilitates the insertion of the plug-in component into the third slot 15 and prevents the plug-in component from being naturally separated without the action of external force.

[0037] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0038] It should also be noted that the various specific technical features described in the above specific implementations can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0039] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
