Description

Technical Field

[0001] The present application relates to the technical field of electric power experiment teaching aids, and in particular to a low-voltage wiring storage and wiring practical training auxiliary device. Background Art

[0002] In current low-voltage wiring practice training, students usually need to manually handle a large number of wires to complete the connection of low-voltage circuits. However, the existing operation method has the following significant defects:

[0003] The wires cannot be managed in a standardized manner during teaching: Students cannot standardize when extracting the required wires, resulting in the random discarding of excess wires and their scattering on the ground. This not only affects the cleanliness of the training environment, but also increases the risk of the wire core being accidentally stepped on and damaged, which may cause safety hazards such as poor contact in the wiring loop and short circuits.

[0004] Practical training time is squeezed and training effect is poor: Due to the inability to standardize the use of wires, the wires are tangled and knotted due to random pulling. Subsequent students need to spend a lot of time to rearrange the wires before wiring practice can continue. Class time is fixed, and the time spent on wiring squeezes the practical training time, resulting in poor wiring training effect.

[0005] The continuity of teaching is impaired: Due to the different habits of students in recycling wires, the remaining wire recycling coils are of different sizes. Coils of different sizes are prone to cross-knotting, which brings inconvenience to the subsequent wiring work. This not only affects the continuity of practical training, but also is not conducive to cultivating students' standardized operating habits.

[0006] In summary, the prior art lacks wiring storage auxiliary tools suitable for use as teaching aids. Summary of the invention

[0071] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0072] The wiring is usually wound on a winding wheel so that the wiring can be stored in a roll, which improves the convenience of storage. Existing winding wheels include both manual and automatic ones. For a manual winding wheel, it is necessary to manually turn the winding wheel to achieve the winding of the wiring. During the winding process, the wiring needs to be guided to a certain extent so that the wiring can be evenly wound on the winding wheel for the next use; the electric winding wheel is driven by a motor to rotate, and can be equipped with a cycloid to guide the wiring to a certain extent, thereby ensuring that the wiring can be evenly wound on the winding wheel. The above two methods can both store the wiring, but they are generally not suitable for the teaching field. For the manual winding wheel, most of the operators in the teaching process are beginners who are not very skilled in operation and have certain difficulties in guiding the wiring. The wiring is prone to cross-knotting after being wound, and the wiring on the winding wheel needs to be sorted out during the secondary use, which is time-consuming, especially in the operation assessment process, which can easily affect the mentality of the trainees. For the electric winding wheel, on the one hand, it has more internal transmission structures and is relatively heavy, and it is also necessary to consider the power supply problem, which makes it inconvenient to transfer the operation. On the other hand, its automatic winding function cannot cultivate the trainees' hands-on ability / operation habits.

[0073] Based on the fact that there is no winding tool suitable for the teaching field in the prior art, the present application embodiment provides a low-voltage wiring storage and wire taking practical training auxiliary device, which can be referred to in conjunction with Figure 1 to Figure 3 The low-voltage wiring storage and wire-taking practical training auxiliary device comprises a housing 100, a driving inner core mechanism 200, a rotating handle 300, a winding mechanism 400, a cylindrical cam 500 and a cycloidal mechanism 600; the housing 100 has a wire passing window 1013, and one axial end of the housing 100 is an open structure; the driving inner core mechanism 200 is rotatably arranged in the housing 100; the rotating handle 300 is connected to the driving inner core mechanism 200 to drive the driving inner core mechanism 200 to rotate around the axis of the housing 100 in the housing 100 The winding mechanism 400 cooperates with the driving inner core mechanism 200 to rotate synchronously; the cylindrical cam 500 is rotatably arranged in the shell 100 and movably sleeved on the winding mechanism 400, and the cylindrical cam 500 cooperates with the driving inner core mechanism 200 to intermittently rotate around the axial direction of the shell 100 under the drive of the driving inner core mechanism 200; the cycloid mechanism 600 has a movable follower rod 603 located in the wire passing window 1013, and the follower rod 603 contacts the working surface 501 of the cylindrical cam 500.

[0074] When in use, the wiring end is passed through the cycloid mechanism 600 and the wire passing window 1013 and then fixed to the winding mechanism 400. The college operates the rotating handle 300 to make the rotating handle 300 drive the driving inner core mechanism 200 to rotate in the shell 100, and the driving inner core mechanism 200 drives the winding mechanism 400 to rotate synchronously, so that the winding mechanism 400 can perform the winding function on the wiring; while winding, the cylindrical cam 500 is driven by the driving inner core mechanism 200 and can rotate intermittently. For example, when the winding mechanism 400 rotates one circle, the cylindrical cam 500 rotates a certain angle. During the rotation of the cylindrical cam 500, it can drive the follower rod 603 to move through its working surface 501, so that the cycloid machine The structure 600 can drive the wiring to move, which means that the wiring can move a certain distance along the axial direction of the shell 100 in the wire passing window 1013, so that the cycloid mechanism 600 can successfully guide the wiring. When the wiring reaches the maximum stroke in the wire passing window 1013, the follower rod 603 corresponds to the highest point of the working surface 501 of the cylindrical cam 500. After continuing to rotate the driving inner core mechanism 200, the follower rod 603 can move in the opposite direction, and so on, and finally the wiring can be evenly wound on the winding mechanism 400; during the winding process, the trainee can operate the rotating handle 300 with one hand, and follow the cycloid mechanism 600 with the other hand to organize the wire to achieve the purpose of training hands-on ability.

[0075] The low-voltage wiring storage and retrieval practical training auxiliary device provided in the embodiment of the present application can drive the inner core mechanism 200 to rotate in the shell 100 by turning the handle 300, and drive the inner core mechanism 200 to rotate by driving the winding mechanism 400 to realize the recovery and winding of the wires, wherein the driving inner core mechanism 200 can drive the cylindrical cam 500 to rotate while driving the inner core mechanism 200 to rotate, and the working surface 501 of the cylindrical cam 500 can drive the cycloid mechanism 600 to reciprocate, so that while the winding mechanism 400 is winding the wire, the wire will move back and forth along the axis of the shell 100 by itself, thereby making the wires wound on the winding mechanism 400 evenly distributed and not easy to cross, and easy to use again, which can save classroom / assessment time and is suitable for use as a teaching aid.
