Technical Field

[0001] This utility model relates to the field of busbar trunking plug-in box technology, specifically an interlocking device for busbar trunking plug-in boxes. Background Technology

[0002] Busbar trunking is a closed metal device composed of copper or aluminum busbar columns. It is used to distribute larger amounts of power to various components in a distributed system. In indoor low-voltage power transmission trunk line projects, it has increasingly replaced electric wires and cables. With the rapid modernization of Chinese cities and the continuous improvement of people's living standards, the country places greater emphasis on electricity safety and personal safety.

[0003] As demands increase, plug-in boxes need to be installed on busbar trunking to distribute power.

[0004] The existing connection between busbar trunking and plug-in boxes is usually fixed with bolts. However, after prolonged use, the bolts will rust, causing instability in the connection between the busbar trunking and the plug-in box. Furthermore, the rusted bolts are difficult to disassemble, increasing the difficulty of maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide an interlocking device for busbar trunking plug-in boxes, in order to solve the problem mentioned in the background art that bolts will rust after prolonged use, resulting in unstable connection between the busbar trunking and the plug-in box, and that the rusted bolts are difficult to disassemble, increasing the difficulty of maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an interlocking device for a busbar trunking plug-in box, comprising a busbar trunking body, connecting grooves on both sides of the upper surface of the busbar trunking body, a pull rod slidably connected to the inner side of the connecting groove, a fixing block fixedly connected to the outer surface of the pull rod, an adjusting groove slidably connected to the outer surface of the fixing block, a guide rod slidably connected to the inner side of the fixing block, a spring wound around the outer surface of the guide rod, a connecting block inserted into the outer surface of the pull rod, an installation groove slidably connected to the outer surface of the connecting block, a plug-in box body fixedly connected to the upper surface of the connecting block, and a box cover connected to the upper surface of the plug-in box body via a hinge.

[0007] Preferably, a sliding groove is provided in the middle of the lower surface of the plug-in box body, a limiting plate is slidably connected to the inner side of the sliding groove, a bidirectional screw is connected to the inner side of the limiting plate by a screw sleeve, a turntable is fixedly connected to the outer surface of the bidirectional screw, and a limiting groove is provided in the middle of the upper surface of the busbar trunking body corresponding to the sliding groove.

[0008] Preferably, the connecting groove is a circular groove, and the connecting groove is provided in two sets on both sides of the upper surface of the busbar trunking body. The pull rod is rod-shaped and slides inside the connecting groove. The adjusting groove is a rectangular groove, and the guide rod is rod-shaped and fixedly connected to the inner side of the adjusting groove. Its function is to pull the two sets of pull rods so that the pull rods slide away from the plug-in box body inside the connecting groove, thereby facilitating the connection block fixedly connected to the lower surface of the plug-in box body and the mounting groove provided on the upper surface of the busbar trunking body.

[0009] Preferably, the fixing block is block-shaped and slidably connected to the inner side of the adjustment groove. The spring is spiral-shaped, with one end fixed to the fixing block and the other end fixedly connected to the inner side of the adjustment groove. Its function is to drive the fixing block to slide synchronously on the outer surface of the guide rod fixed inside the adjustment groove through the sliding of the pull rod, thereby compressing the spring.

[0010] Preferably, the mounting groove is a rectangular recess, located on the upper surface of the busbar trunking body near the end of the connecting groove. The inner side of the connecting block has a cylindrical groove. The connecting groove is connected to the connecting block by inserting into the groove. Its function is to slide the two sets of connecting blocks fixed on both sides of the lower surface of the plug-in box body into the interior of the mounting groove. Under the elastic action of the spring, the fixing block quickly slides back to its original position inside the adjusting groove, thereby driving the pull rod to slide synchronously. Thus, the pull rod, through the insertion of the connecting block, initially fixes the plug-in box body to the upper part of the busbar trunking body, eliminating the need for bolts for fixing and facilitating subsequent disassembly of the plug-in box body.

[0011] Preferably, the chute is a rectangular groove, the limiting plate is an "L"-shaped plate, and there are two sets of limiting plates. The limiting plates are slidably connected to the inner side of the chute, and the bidirectional screw is rotatably connected to the inner side of the chute. The bidirectional screw is connected to the two sets of limiting plates through a screw sleeve. Its function is to slide the connecting block fixedly connected to the lower surface of the plug-in box body into the inner side of the mounting groove, so that the two sets of limiting plates connected to the lower surface of the plug-in box body are located inside the limiting groove opened on the upper surface of the busbar trunking body. Thus, by rotating the turntable, the turntable drives the bidirectional screw to rotate, so that the two sets of limiting plates slide away from each other inside the limiting groove.

[0012] Preferably, the limiting groove is a "T"-shaped groove, and the lower surface of the limiting plate is slidably connected to the inner side of the limiting groove. Its function is to allow the bottom of the two sets of limiting plates to slide inside the limiting groove by rotating the turntable. This allows the two sets of limiting plates to engage inside the limiting groove when the turntable cannot rotate, thereby reinforcing the installation of the busbar trunking body and the plug-in box body, making the connection between the two sets tighter and more stable.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By pulling the two sets of pull rods, the pull rods slide away from the plug-in box body on the inner side of the connecting groove. The sliding of the pull rods causes the fixing blocks to slide synchronously on the outer surface of the guide rod fixed on the inner side of the adjusting groove, thereby compressing the spring. Then, by sliding the two sets of connecting blocks fixed on both sides of the lower surface of the plug-in box body into the interior of the mounting groove, the fixing blocks quickly slide back to their original position on the inner side of the adjusting groove under the elastic action of the spring, thereby causing the pull rods to slide synchronously. Thus, the pull rods, through the plug-in connecting blocks, initially fix the plug-in box body to the upper part of the busbar trunking body, eliminating the need for bolts for fixing and facilitating subsequent disassembly of the plug-in box body.

[0015] 2. By rotating the turntable, the turntable drives the bidirectional lead screw to rotate, causing the two sets of limiting plates to slide away from each other inside the limiting groove until the turntable can no longer rotate. This locks the two sets of limiting plates inside the limiting groove, thereby reinforcing the installation of the busbar trunking body and the plug-in box body, making the two sets of connections tighter and more stable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 One embodiment provided by this utility model:

[0024] An interlocking device for a busbar trunking plug-in box includes a busbar trunking body 1. Connecting grooves 2 are provided on both sides of the upper surface of the busbar trunking body 1. A pull rod 3 is slidably connected to the inner side of the connecting groove 2. A fixing block 4 is fixedly connected to the outer surface of the pull rod 3. An adjusting groove 5 is slidably connected to the outer surface of the fixing block 4. A guide rod 6 is slidably connected to the inner side of the fixing block 4. A spring 8 is wound around the outer surface of the guide rod 6. A connecting block 10 is inserted into the outer surface of the pull rod 3. An installation groove 9 is slidably connected to the outer surface of the connecting block 10. A plug-in box body 11 is fixedly connected to the upper surface of the connecting block 10. A box cover 12 is connected to the upper surface of the plug-in box body 11 via a hinge.

[0025] Furthermore, a sliding groove 13 is provided in the middle of the lower surface of the plug-in box body 11. A limiting plate 14 is slidably connected to the inner side of the sliding groove 13. A two-way screw rod 15 is connected to the inner side of the limiting plate 14 through a screw sleeve. A turntable 16 is fixedly connected to the outer surface of the two-way screw rod 15. A limiting groove 17 is provided in the middle of the upper surface of the busbar trunking body 1 corresponding to the sliding groove 13.

[0026] Furthermore, the connecting groove 2 is a circular groove, and two sets of the connecting groove 2 are opened on both sides of the upper surface of the busbar trunking body 1. The pull rod 3 is rod-shaped and slides inside the connecting groove 2. The adjusting groove 5 is a rectangular groove, and the guide rod 6 is rod-shaped and fixedly connected to the inner side of the adjusting groove 5. Its function is to pull the two sets of pull rods 3 so that the pull rod 3 slides away from the plug-in box body 11 inside the connecting groove 2, thereby facilitating the connection block 10 fixedly connected to the lower surface of the plug-in box body 11 and the mounting groove 9 opened on the upper surface of the busbar trunking body 1.

[0027] Furthermore, the fixing block 4 is block-shaped and slidably connected to the inner side of the adjusting groove 5. The spring 8 is spiral-shaped, with one end of the spring 8 fixed to the fixing block 4 and the other end of the spring 8 fixedly connected to the inner side of the adjusting groove 5. Its function is to drive the fixing block 4 to slide synchronously on the outer surface of the guide rod 6 fixed inside the adjusting groove 5 through the sliding of the pull rod 3, thereby compressing the spring 8.

[0028] Furthermore, the mounting groove 9 is a rectangular groove. The mounting groove 9 is opened on the upper surface of the busbar trunking body 1 near the end of the connecting groove 2. The inner side of the connecting block 10 is provided with a cylindrical groove. The connecting groove 2 is connected to the connecting block 10 through the groove. Its function is to slide the two sets of connecting blocks 10 fixed on both sides of the lower surface of the plug-in box body 11 into the interior of the mounting groove 9. Under the elastic action of the spring 8, the fixing block 4 is quickly slid and reset inside the adjusting groove 5, thereby driving the pull rod 3 to slide synchronously. Thus, the pull rod 3 is connected to the plug-in box body 11 above the busbar trunking body 1 by inserting the connecting block 10, so that bolts are no longer needed for fixed connection, which facilitates the subsequent disassembly of the plug-in box body 11.

[0029] Furthermore, the slide groove 13 is a rectangular groove, the limiting plate 14 is an "L" shaped plate, and there are two sets of limiting plates 14. The limiting plates 14 are slidably connected to the inner side of the slide groove 13, and the bidirectional screw 15 is rotatably connected to the inner side of the slide groove 13. The bidirectional screw 15 is connected to the two sets of limiting plates 14 through a screw sleeve. Its function is to slide the connecting block 10 fixedly connected to the lower surface of the plug-in box body 11 into the inner side of the mounting groove 9, so that the two sets of limiting plates 14 connected to the lower surface of the plug-in box body 11 are located inside the limiting groove 17 opened on the upper surface of the busbar trunking body 1. Then, by rotating the turntable 16, the turntable 16 drives the bidirectional screw 15 to rotate, so that the two sets of limiting plates 14 slide away from each other inside the limiting groove 17.

[0030] Furthermore, the limiting groove 17 is a "T"-shaped groove, and the lower surface of the limiting plate 14 is slidably connected to the inner side of the limiting groove 17. Its function is to allow the bottom of the two sets of limiting plates 14 to slide inside the limiting groove 17 through the rotation of the turntable 16. This allows the two sets of limiting plates 14 to engage inside the limiting groove 17 when the turntable 16 cannot rotate, thereby reinforcing the installation of the busbar trunking body 1 and the plug-in box body 11, making the connection between the two sets tighter and more stable.

[0031] Working principle: Connecting grooves 2 are provided on both sides of the upper surface of the busbar trunking body 1. A pull rod 3 is slidably connected to the inner side of the connecting groove 2. A fixing block 4 is fixedly connected to the outer surface of the pull rod 3. An adjusting groove 5 is slidably connected to the outer surface of the fixing block 4. A guide rod 6 is slidably connected to the inner side of the fixing block 4. A spring 8 is wound around the outer surface of the guide rod 6. A connecting block 10 is inserted and connected to the outer surface of the pull rod 3. An installation groove 9 is slidably connected to the outer surface of the connecting block 10. A plug-in box body 11 is fixedly connected to the upper surface of the connecting block 10. A box cover 12 is connected to the upper surface of the plug-in box body 11 via a hinge. By pulling the two sets of pull rods 3, the pull rods 3 move outward from the inner side of the connecting groove 2. The pull rod 3 slides away from the plug-in box body 11. Through the sliding of the pull rod 3, the fixing block 4 slides synchronously on the outer surface of the guide rod 6 fixed inside the adjustment groove 5, thereby compressing the spring 8. Then, by sliding the two sets of connecting blocks 10 fixed on both sides of the lower surface of the plug-in box body 11 into the interior of the mounting groove 9, the fixing block 4 slides back to its original position inside the adjustment groove 5 under the elastic action of the spring 8, thereby driving the pull rod 3 to slide synchronously. Thus, the pull rod 3, through the plug-in connecting block 10, initially fixes the plug-in box body 11 above the busbar trunking body 1, so that bolts are no longer needed for fixing, which facilitates the subsequent disassembly of the plug-in box body 11.

[0032] A sliding groove 13 is provided in the middle of the lower surface of the plug-in box body 11. A limiting plate 14 is slidably connected to the inner side of the sliding groove 13. A double-acting screw 15 is connected to the inner side of the limiting plate 14 by a screw sleeve. A turntable 16 is fixedly connected to the outer surface of the double-acting screw 15. A limiting groove 17 is provided in the middle of the upper surface of the busbar trunking body 1 corresponding to the sliding groove 13. After the plug-in box body 11 is initially fixed to the busbar trunking body 1 by inserting the connecting block 10 with the pull rod 3, in order to ensure the stability of the connection between the plug-in box body 11 and the busbar trunking body 1, the turntable 16 is rotated, which drives the double-acting screw 15 to rotate. This causes the two sets of limiting plates 14 to slide away from each other in the inner side of the limiting groove 17 until the turntable 16 can no longer rotate. This locks the two sets of limiting plates 14 in the inner side of the limiting groove 17, thereby reinforcing the installation of the busbar trunking body 1 and the plug-in box body 11, making the connection between the two sets tighter and more stable.
