Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, and specifically relates to a junction box structure for a servo motor. Background Technique

[0002] The junction box is one of the electrical accessories, generally playing the role of protecting wires and connecting wires. The traditional junction box is generally fixed by bolts during installation. When wiring the junction box, the top cover needs to be opened and closed. Due to the low manufacturing precision of the traditional junction box, there are easily gaps when the top cover is placed on the junction box. Therefore, in order to prevent water from splashing into the junction box, it is protected by wrapping with other tools, but there are still some problems.

[0003] For example, the patent document with the publication number CN212162688U discloses: "A simplified junction box, including a junction box body. The upper part of the junction box body is open. Through holes are directly opened on the bottom plate and the four side plates of the junction box body. A screw mounting hole is also opened on the bottom plate of the junction box body. Nut angle plate assembly grooves are symmetrically distributed on the inner walls of both sides of the junction box body. Nut angle plates are provided in the nut angle plate assembly grooves. Bolt holes are provided on the nut angle plates. A flange extending outwards is formed at the outer edge of the upper opening of the junction box body. Reinforcing ribs are distributed on the flange. A connecting concave hanging ring is provided on the outer wall of one side of the junction box body, and a connecting pin is provided on the outer wall of the other side of the junction box body. By pre-opening through holes on the bottom plate and side plates of the junction box, the knocking-off process of the knocking-off holes during the construction process is avoided, and the work efficiency is improved."

[0004] However, when the junction box body of the above device is fixed, since the junction box is generally exposed outside, and the servo motor scenario includes outdoor environments, rainwater will pour onto the junction box during rain. There is a gap between the junction box and the cover plate, resulting in rainwater easily flowing into the interior through the junction box. Moreover, when the cable passes through the through hole, due to the different sizes of the cables, it is difficult for the cables to fill the through hole completely, making it easy for rainwater to flow into the junction box from the cable, eroding the cable and easily causing potential cable short-circuit hazards. Therefore, a new junction box structure is needed to solve the above problems. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a junction box structure for a servo motor to solve the problem that rainwater easily flows into the interior through the top and through holes of the junction box as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions, and discloses a wiring box structure for a servo motor, including: a wiring box body, both the front and rear sides of the wiring box body are fixedly connected with threading pipes, both sides of the threading pipes are fixedly connected with connecting plates, the inner wall of the connecting plates is connected with springs, one end of the springs is connected with sliding blocks, the front of the sliding blocks is fixedly connected with connecting columns, one side of the connecting columns is fixedly connected with connecting plates, one side of the connecting plates is fixedly connected with sealing rings, a baffle is lapped on the top of the wiring box body, sealing strips are fixedly connected to the four circumferences of the bottom of the baffle, and screws are threadedly connected to the four circumferences of the top of the baffle, and the surface of the screws is threadedly connected to the inner wall of the wiring box body.

When the baffle and the junction box are fixed, the sealing strip is squeezed, effectively reducing the gap between the two. The closed ring holds the cable, and the closed ring fits the conduit, effectively reducing the opening of the conduit, making the opening fit the cable, thereby reducing the gap between the cable and the conduit and reducing the probability of rain splashing into the junction box.

[0016] 2. Through the combined use of a rain shield and a connecting ring, when installing the junction box, by observing the placement direction of the junction box and the direction of rain splash, the rain shield can be moved in a circular motion around the dust-proof net to the corresponding position and fixed, enabling the rain shield to effectively block rain, ensuring the heat dissipation of the junction box while reducing rain splash, thereby improving the rain protection effect.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer toFigure 1 , Figure 2 and Figure 3 , a wiring box structure for a servo motor:

[0025] It includes: a wiring box body 1. Both the front and rear sides of the wiring box body 1 are fixedly connected with threading pipes 2. Both sides of the threading pipes 2 are fixedly connected with connecting plates 3. The inner wall of the connecting plates 3 is connected with a spring 4. One end of the spring 4 is connected with a sliding block 5. The front of the sliding block 5 is fixedly connected with an adapter column 6. One side of the adapter column 6 is fixedly connected with an adapter plate 7. One side of the adapter plate 7 is fixedly connected with a sealing ring 8. A baffle 9 is lapped on the top of the wiring box body 1. Sealing strips 10 are fixedly connected to the four circumferences at the bottom of the baffle 9. Screws 11 are threadedly connected to the four circumferences at the top of the baffle 9, and the surface of the screws 11 is threadedly connected to the inner wall of the wiring box body 1. Support blocks 12 are fixedly connected to both sides of the back of the wiring box body 1. A telescopic rod 13 is slidably connected to the inner wall of the support blocks 12. The top of the telescopic rod 13 is fixedly connected with an adapter block 14. A connecting rod 15 is fixedly connected to the middle of the two adapter blocks 14, and one side of the connecting rod 15 is fixedly connected to the inner wall of the baffle 9.

[0026] When using this device to carry out rain protection work on the wiring box body 1, pass the cable through the threading pipe 2 and wire it inside the wiring box body 1. At the same time, pull the adapter plate 7 to both sides, so that the adapter plate 7 drives the sealing ring 8 to move, the adapter plate 7 drives the adapter column 6 to move, the adapter column 6 drives the sliding block 5 to move to both sides, and the adapter column 6 compresses the spring 4. Then pull out the cable from another threading pipe 2, and then release the adapter plate 7, so that the spring 4 pushes the sliding block 5, making the sealing ring 8 move towards the cable and clamp the cable. At this time, the sealing ring 8 fits against the threading pipe 2, and the sealing ring 8 is made of rubber, so that the gap between the sealing ring 8 and the threading pipe 2 is small, thus effectively improving the effect of intercepting rainwater. Then pull the connecting rod 15 upwards, so that the connecting rod 15 drives the baffle 9 to move, the connecting rod 15 drives the adapter block 14 to move, the adapter block 14 drives the telescopic rod 13 at the bottom to extend out of the support block 12. Then rotate the baffle 9 so that the baffle 9 is parallel to the wiring box body 1. Then press the baffle 9 downwards so that the sealing strip 10 is inserted into the slot at the top of the wiring box body 1, and rotate the screw 11 through the baffle 9 and the wiring box body 1. The sealing strip 10 is made of rubber, so that it can deform, and the wiring box body 1 and the baffle 9 squeeze the sealing strip 10, thereby reducing the gap between the wiring box body 1 and the baffle 9.

[0027] Please refer to Figure 1 and Figure 2 , fixing plates 16 are fixedly connected to the bottoms of the left and right sides of the wiring box body 1, and bolts 17 are threadedly connected to the tops of the fixing plates 16.

[0028] When fixing the wiring box body 1 with this device, stick the fixing plate 16 to the position to be fixed, and then pass the bolt 17 through the fixing plate 16 and rotate it into the external connecting plate, thereby completing the connection and fixing of the wiring box.

[0029] Please refer to Figure 1 、 Figure 2 and Figure 5 On both inner walls of the left and right sides of the wiring box body 1, dust-proof nets 18 are fixedly connected. On both left and right sides of the wiring box body 1, connecting rings 19 are fixedly connected. A rain shield 20 is slidably connected to the inner wall of the connecting ring 19. Fixing grooves 21 are fixedly connected to the four surrounding sides of the connecting ring 19. A connecting pipe 22 is fixedly connected to one side of the rain shield 20. A fixing rod 23 is threadedly connected to the inner wall of the connecting pipe 22, and the tail end of the fixing rod 23 is threadedly connected to the inner wall of the fixing groove 21. The horizontal longitudinal section of the rain shield 20 is arc-shaped, and the radius of the rain shield 20 is the same as the radius of the horizontal longitudinal section of the connecting ring 19.

[0030] When protecting the heat dissipation holes with this device, after fixing the wiring box body 1, rotate the fixing rod 23 so that the fixing rod 23 disengages from the fixing groove 21. At this time, the rain shield 20 is disengaged. Then rotate the rain shield 20 so that the rain shield 20 makes a circular movement around the dust-proof net 18 on the inner wall of the connecting ring 19. After adjusting the rain shield 20 to an appropriate position, move the connecting pipe 22 to the front of the nearest fixing groove 21. Then rotate the fixing rod 23 in the reverse direction so that the fixing rod 23 rotates and inserts into the opposite fixing groove 21, thereby completing the fixing of the rain shield 20 and enabling the rain shield 20 to intercept more rainwater.

[0031] Working principle: Stick the bottom of the wiring box body 1 to the designated external connecting plate, and then rotate the bolt 17 through the fixing plate 16 and insert it into the external connecting plate, thereby completing the connection and fixing of the wiring box body 1. Then insert multiple cables into the wiring box body 1 through the through pipes 2 on the front and back sides of the wiring box body 1 and connect and fix multiple groups of cables. At this time, pull the closing ring 8 and push the closing ring 8 through the spring 4 so that the closing ring 8 clamps the cables and seals the opening of the through pipe 2, making the opening of the through pipe 2 smaller, thereby reducing the probability of rainwater splashing in. Then pull up and rotate the baffle 9 so that the baffle 9 is parallel to the wiring box body 1. Then press down the baffle 9 so that the sealing strip 10 is inserted into the slot on the top of the wiring box body 1. Then rotate the screw 11 through the wiring box body 1 and the baffle 9 to complete the sealing and fixing between the two. Then rotate the fixing rod 23 so that the rain shield 20 can be moved. Then move the rain shield 20 to the corresponding position so that the rain shield 20 can intercept more rainwater. Then rotate the fixing rod 23 in the reverse direction so that the fixing rod 23 inserts into the opposite fixing groove 21, thereby completing the fixing of the rain shield 20.
