Description

Technical Field

[0001] This utility model relates to the field of electrical training and teaching equipment technology, and in particular to a wiring trough connection structure for an electrical training platform. Background Technology

[0002] An electrical training platform is a device platform used for electrical engineering teaching, training, and skills practice. It typically integrates various electrical components, instruments, and operating modules, aiming to provide learners with an environment that simulates the operation of a real electrical system. A circuit usually consists of components such as circuit breakers, wires, contactors, cable trays, and relays. These components form the basis of electrical control circuits. Students can gain a deeper understanding of their working principles and control logic by wiring, debugging, and other operations on the training platform.

[0003] Currently, when connecting existing guide rails to electrical training platforms, screws and nuts are typically used to install wire channels on the platform's wiring panel. Since the screws need to be installed symmetrically on the wire channels and tightened one by one, students often spend a lot of time installing the wire channels, resulting in low efficiency and impacting class time. Therefore, the practicality is insufficient and needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wiring trough connection structure for an electrical training platform, which solves the technical problem of inconvenient installation of existing wiring troughs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wiring trough connection structure for an electrical training platform includes an electrical training platform body and a trough body. The surface of the electrical training platform body is provided with a wiring panel, and the surface of the wiring panel has multiple gap square grooves.

[0009] A one-way crank snap-fit ​​structure is fixedly installed on the surface of the wire groove body;

[0010] The snap-fit ​​structure includes a first P-shaped snap-fit ​​block, which snaps into the corner of the gap square groove. The inside of the trough body is provided with a storage groove, which is on the same side as the first P-shaped snap-fit ​​block. A through groove is provided inside the trough body, and a damping bearing is provided inside the through groove. The outer ring of the damping bearing is fixedly installed with the through groove, and a rotating shaft is fixedly installed on the inner ring of the damping bearing. The rotating shaft is partially exposed outside the trough body.

[0011] Preferably, a disc is fixedly installed on the circumferential surface of the rotating shaft, the disc is located inside the storage groove, a U-shaped block is fixedly installed on the side of the storage groove away from the disc, a sliding groove is provided inside the U-shaped block, a transmission bar is slidably installed inside the sliding groove, a first cylinder is fixedly installed on the surface of the disc, and a second cylinder is fixedly installed on the surface of the transmission bar.

[0012] Preferably, a connecting rod is rotatably installed between the first cylinder and the second cylinder, and a second P-shaped locking block is fixedly installed on the surface of the transmission bar away from the second cylinder. The second P-shaped locking block engages with the corner of the gap square groove.

[0014] (III) Beneficial Effects

[0015] 1. By first inserting the first P-shaped locking block into the corner of the gap square groove, and then rotating the shaft, the shaft drives the disc to rotate synchronously. The first cylinder generates a radial force on the connecting rod, causing the connecting rod to pull the transmission bar towards the first P-shaped locking block through the second cylinder, thus completing the crank motion. This allows the second P-shaped locking block to be pulled into the corner of the gap square groove and locked onto the wiring panel, thus completing the installation of the cable tray body. This method is convenient, improves the installation efficiency of the cable tray body, saves installation time, and enhances practicality.

[0016] Second, by setting up a U-shaped block and a limiting groove, when the connecting rod pulls the transmission bar along the second cylinder to move towards the first P-shaped block, the transmission bar can drive the limiting block to slide actively with the sliding groove and the limiting groove inside the U-shaped block, thereby providing additional limiting and increasing stability.

[0025] Example

[0026] like Figure 1 - Figure 6 As shown, the technical solution in this application embodiment effectively solves the technical problem of inconvenient installation of existing cable trays. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a wiring trough connection structure for an electrical training platform, including an electrical training platform body 11 and a trough body 12. The surface of the electrical training platform body 11 is provided with a wiring panel 29, and the surface of the wiring panel 29 has multiple gap square grooves 31.

[0028] A one-way crank snap-fit ​​structure is fixedly installed on the surface of the cable tray body 12;

[0029] The snap-fit ​​structure includes a first P-shaped snap-fit ​​block 13, which snaps into the corner of the square slot 31. A storage slot 14 is provided inside the cable tray body 12, on the same side as the first P-shaped snap-fit ​​block 13. A through slot 15 is provided inside the cable tray body 12, and a damping bearing 16 is provided inside the through slot 15. The outer ring of the damping bearing 16 is fixedly installed in the through slot 15, and a rotating shaft 17 is fixedly installed in the inner ring of the damping bearing 16. A portion of the rotating shaft 17 is exposed outside the cable tray body. Externally, a disc 18 is fixedly mounted on the circumferential surface of the rotating shaft 17. The disc 18 is located inside the storage slot 14. A U-shaped block 19 is fixedly mounted on the side of the storage slot 14 away from the disc 18. The U-shaped block 19 has a sliding groove 21 inside, and a transmission bar 22 is slidably mounted inside the sliding groove 21. A first cylinder 23 is fixedly mounted on the surface of the disc 18, and a second cylinder 24 is fixedly mounted on the surface of the transmission bar 22. A connecting rod is rotatably mounted between the first cylinder 23 and the second cylinder 24. A second P-shaped locking block 26 is fixedly installed on the surface of the rod 25 and the transmission bar 22 away from the second cylinder 24. The second P-shaped locking block 26 engages with the corner of the gap square groove 31. The second P-shaped locking block 26 is parallel to the first P-shaped locking block 13. When it is necessary to install the wire trough body 12 on the wiring panel 29, the first P-shaped locking block 13 is first inserted into the corner of the gap square groove 31. Then, the rotating shaft 17 is rotated, so that the rotating shaft 17 drives the disc 18 to rotate synchronously. The first cylinder 23 generates a radial force on the connecting rod 25, so that the connecting rod 25 pulls the transmission bar 22 as a whole towards the first P-shaped locking block 13 through the second cylinder 24, thereby completing the crank motion. Then, the second P-shaped locking block 26 can be pulled into the corner of the gap square groove 31 and locked on the wiring panel 29, thus completing the installation of the wire trough body 12. This is convenient and can also improve the installation efficiency of the wire trough body 12, save installation time, and improve practicality.

[0030] A limiting groove 27 is symmetrically formed through the side wall of the slide groove 21. A limiting block 28 is slidably installed inside each limiting groove 27. Both limiting blocks 28 are fixedly installed to the transmission bar 22. The limiting blocks 28 are located on both sides of the transmission bar 22. By setting the U-shaped block 19 and the limiting groove 27, when the connecting rod 25 pulls the transmission bar 22 as a whole towards the first P-shaped locking block 13 through the second cylinder 24, the transmission bar 22 can drive the limiting block 28 to slide actively with the slide groove 21 and the limiting groove 27 inside the U-shaped block 19, thereby providing additional limiting and increasing stability.

[0031] Insulating ceramic sealing plates 32 are symmetrically fixedly installed inside the through groove 15. Both insulating ceramic sealing plates 32 are on both sides of the damping bearing 16 and are rotatably installed on the rotating shaft 17. By installing insulating ceramic sealing plates 32 on both sides of the damping bearing 16, it is possible to avoid the copper core wires of some wires being exposed and coming into contact with the damping bearing 16 during wiring, which would cause the damping bearing 16 to be energized and damaged, thus improving the protection.

[0032] Working principle:

[0033] First, when it is necessary to install the wire trough body 12 on the wiring panel 29 of the electrical training platform body 11 (the wire trough body 12 and the structure used to snap the wiring panel 29 are all made of insulating material, except for the damping bearing 16), the wire trough body 12 can be picked up, and the first P-shaped locking block 13 and the second P-shaped locking block 26 can be placed into the gap square groove 31 of the wiring panel 29 respectively. At this time, the operator can move the wire trough body 12 as a whole away from the first P-shaped locking block 13, so that the first P-shaped locking block 13 passes through the gap square groove. The corner of 31 is secured to the wiring panel 29. Then, the operator can rotate the shaft 17 counterclockwise, causing the shaft 17 to drive the inner ring of the damping bearing 16 (the damping bearing 16 is existing technology, a type of bearing that has a certain torque force when rotating. The damping effect is achieved through damping grease and a super-strong sealing cover. The damping torque of the damping bearing 16 can be customized according to the requirements. Generally, the larger the bearing rotation diameter, the greater the torque. Bearings with the same rotation diameter can also be designed with different damping torques by adjusting the grease viscosity and the sealing effect of the sealing cover).

[0034] In the second step, when the rotating shaft 17 rotates, the rotating shaft 17 will cause the disc 18 to rotate synchronously, so that the first cylinder 23 generates a radial force on the connecting rod 25, causing the connecting rod 25 to pull the transmission bar 22 towards the first P-shaped locking block 13 through the second cylinder 24. This causes the transmission bar 22 to drive the limiting block 28 to slide actively with the sliding groove 21 and the limiting groove 27 in the U-shaped block 19, thereby pulling the second P-shaped locking block 26 into the corner of the gap square groove 31 and locking it on the wiring panel 29. At this time, both first P-shaped locking blocks 13 and the wiring panel 29 are locked inside the wiring panel 29, and the wire groove body 12 can be locked on the wiring panel 29. At this time, the installation is completed.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
