Description

Technical Field

[0001] This utility model belongs to the technical field of elevator control cabinet accessories, specifically relating to an internal terminal block installation structure for an elevator control cabinet. Background Technology

[0002] During elevator installation, various electrical components and monitoring devices related to the elevator need to be connected to the control cabinet for controlling elevator operation and daily maintenance. Since there are many wires in the control cabinet, multiple wires need to be connected through terminal blocks to meet the power supply requirements and facilitate later maintenance.

[0003] However, in existing terminal blocks, many are fixed to the mounting plate inside the control cabinet using bolts during installation. Usually, the bolts used to fix the terminal blocks are small and few in number. During daily maintenance, the bolts on the terminal blocks are easily loosened by vibration or pulling of the wires, affecting the stability of the terminal blocks. Secondly, when adjusting or installing terminal blocks, tools are needed to tighten or loosen the bolts, and manual adjustment is not possible, which reduces the flexibility of terminal block installation.

[0004] Therefore, a terminal block mounting structure inside the elevator control cabinet is designed to overcome the aforementioned technical defects. Utility Model Content

[0023] This specific embodiment is a terminal block installation structure inside an elevator control cabinet, and its structural diagram is shown below. Figures 1-4 As shown, it includes a mounting plate 1 and a terminal block 2. The terminal block 2 has a mounting hole on its side wall, and the mounting plate 1 has a plurality of round holes 3 on its side wall. A connector is provided between the mounting hole and the round hole 3.

[0024] The connector includes a hollow rod 4 disposed between the mounting hole and the round hole 3. An adjusting plate 5 is fitted on the side wall of the hollow rod 4. A transmission rod 6 is rotatably connected to the inner cavity of the hollow rod 4. A pull ring 7 is fitted at one end of the hollow rod 4, and a tightening component is provided at the other end of the hollow rod 4.

[0025] like Figures 2-4 As shown, the clamping assembly includes four sets of connecting plates 10 fixedly connected to the end face of the hollow rod 4. Each set of connecting plates 10 consists of two plates, and a round shaft 12 is rotatably connected between every two connecting plates 10. A worm gear 13 and a fixing plate 11 are fixedly connected to the side wall of each round shaft 12. The fixing plate 11 is U-shaped, and a baffle 14 is fixedly connected to the side wall of each fixing plate 11. The baffles 14 are arranged in a circular array. After the terminal block 2 is fixed, the baffles 14 can be subjected to uniform force, which helps to improve stability. A worm 9 is fixedly connected to one end of the transmission rod 6, and the worm 9 meshes with the worm gear 13. A rotating rod 8 is fixedly connected to the other end of the worm 9.

[0026] The transmission assembly allows manual rotation of the rotating rod 8 to drive the worm gear 9 to rotate. The worm gear 9 then drives the worm wheel 13 to expand outward or return inward simultaneously, achieving convenient fixation. Compared to the traditional bolt installation method, this solution will not loosen or fall off after installation.

[0027] like Figure 2 and Figure 3 As shown, anti-slip textures are provided on the side wall of the rotating rod 8. By setting anti-slip textures, the friction between the rotating rod 8 and the user's hand can be increased, making the rotation of the rotating rod 8 more stable.

[0028] like Figure 2 and Figure 3 As shown, the hollow rod 4 has an internal thread 15 on its side wall, and the adjusting plate 5 is annular and is threadedly connected to the side wall of the hollow rod 4.

[0029] Specifically, the distance between the adjusting plate 5 and the baffle 14 can be adjusted by rotating the adjusting plate 5 to accommodate different installation depths. Alternatively, the position of the adjusting plate 5 can be adjusted after the baffle 14 is opened to fix the terminal 2.

[0030] like Figure 2 As shown, the side wall of the adjustment plate 5 has a hexagonal structure. It can be adjusted manually or with a wrench, offering high flexibility.

[0031] Working principle: When it is necessary to install the terminal block 2, first place the terminal block 2 in a suitable position on the mounting plate 1. Then, according to the model of the terminal block 2 and the installation position, rotate the adjusting plate 5 to move it to the appropriate position. Then, insert the hollow rod 4 into the mounting hole and the round hole 3. Then, rotate the rotating rod 8 to drive the worm gear 9 to rotate through the transmission rod 6. The worm gear 9 meshes with the worm wheel 13 to drive the round shaft 12 to rotate. The round shaft 12 drives the baffle 14 to expand outward synchronously through the fixing plate 11. After the baffle 14 expands to a certain angle, it is tightly attached to the mounting plate 1, thus completing the installation of the terminal block 2. When it is necessary to disassemble the terminal block 2, simply reverse the rotating rod 8, which effectively improves its installation convenience.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
