Description

Technical Field

[0001] This utility model relates to the field of tubular busbar installation technology, specifically to an adjustable tubular busbar connector. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in various industries has increased rapidly, especially with the rise of numerous high-rise buildings and large factory workshops. Traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems, and the parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in busbar trunking, as a new type of power distribution conductor, has emerged. A busbar refers to a shared pathway on which multiple devices are connected in parallel branches. When using the same busbar, corresponding connectors are needed to connect the two busbars. However, in actual use, the following drawbacks still exist: 1. Existing connectors do not have an adjustable length function. Therefore, when the tubular busbar is too heavy, the connector cannot increase the support length of the tubular busbar, thus affecting the connection stability of the tubular busbar; 2. When using connectors, since the connectors do not have a buffering function, the tubular busbar will impact the connector during installation and connection, causing excessive load on the connector structure and affecting the connector's service life. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable tubular busbar connector, which solves the problems raised in the current background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An adjustable tubular busbar connector includes a base plate, a buffer device, and a cross linkage device. An intermediate connecting element is positioned above the base plate, and a buffer device is positioned between the base plate and the intermediate connecting element. Connecting cylinders are fixedly installed at both ends of the intermediate connecting element. An extension cylinder is movably sleeved at the other end of the connecting cylinder, and a flange is provided at the other end of the extension cylinder. Fixing plates are provided at both the top and bottom ends of the connecting cylinder, and a connecting plate is fixedly installed at the other end of each fixing plate. A fixing bolt is threaded to the top of the connecting plate. Several threaded holes are provided at both the top and bottom ends of the extension cylinder, arranged linearly from left to right. The fixing bolt is threaded into the threaded hole on the side closest to the extension cylinder. Sealing rings are provided at both ends of the connecting cylinder, and these sealing rings are compatible with the inner cavity of the connecting tube. Symmetrical clamping devices are provided inside the connecting cylinder.

[0005] Preferably, the buffer device includes symmetrical support blocks, a first slide rod is arranged between the symmetrical support blocks, the first slide rod is slidably connected to a symmetrical first moving block, a first transverse spring is arranged between the symmetrical first moving blocks and on the periphery of the first slide rod, a second slide rod is arranged between the symmetrical support blocks and above the first slide rod, the second slide rod is slidably connected to a symmetrical second moving block, a second transverse spring is arranged between the support block and the second moving block and on the periphery of the second slide rod, a first connecting rod is rotatably connected to the front of the first moving block, the other end of the first connecting rod is rotatably connected to the second moving block, a second connecting rod is rotatably connected to the front of the second moving block, the other end of the second connecting rod is rotatably connected to a connecting block, a buffer plate is fixedly installed at the top of the connecting block, a symmetrical sleeve is arranged between the buffer plate and the support plate, a first vertical spring is arranged inside the sleeve, a movable plate is arranged at the top of the first vertical spring, a guide rod is arranged at the top of the movable plate, the guide rod is movably connected to the sleeve, and a cross linkage device is arranged between the buffer plate and the support plate and on the inner side of the sleeve.

[0006] Preferably, the clamping device includes a tension plate, a symmetrical tension rod is fixedly installed at the other end of the tension plate, a clamping plate is provided at the other end of the tension rod, the tension rod and the intermediate connecting element are movably connected, the clamping plate is located inside the intermediate connecting element, a spring is provided between the clamping plate and the intermediate connecting element and outside the tension rod, and an arc-shaped silicone plate is provided on the inner side of the clamping plate.

[0007] Preferably, the cross linkage device includes a slide groove, and four sets of slide grooves are respectively provided at the top of the buffer plate and the bottom of the support plate. A slider is slidably connected in each of the four sets of slide grooves. An outer cross arm and an inner cross arm are respectively hinged to the diagonal of the slider. The outer cross arm and the inner cross arm are arranged crosswise, and a hinge shaft is rotatably connected at the intersection of the outer cross arm and the inner cross arm.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are: The adjustable tubular busbar connector provided by this utility model clamps two tubular busbars using a clamping device. First, the fixing bolt is turned to move one end of the fixing bolt out of the threaded hole. Then, the extension tube is moved left and right on the surface of the connecting tube until the extension tube is adjusted to a suitable position. Then, the fixing bolt is turned in the opposite direction so that one end of the fixing bolt is threaded into the corresponding threaded hole, thereby fixing the extension tube. This allows the device to adjust the length according to actual needs, which in turn gradually increases the area supported at the end of the tubular busbar, greatly improving the stability of the tubular busbar connection. This invention incorporates a buffer device between the base plate and the intermediate connecting element. After the tubular busbar is installed inside the connecting cylinder, the intermediate connecting element, under its own weight, causes the support plate to move downwards. The support plate compresses the first vertical spring via a guide rod. The first vertical spring is frictionally connected to the inside of the sleeve via a movable plate, thus achieving the first unloading of the force on the support plate. Simultaneously, the support plate transmits the force to the first and second connecting rods via the buffer plate. The first and second connecting rods drive the first and second moving blocks to slide on the first and second sliding rods respectively, allowing the first and second transverse springs to unload the force a second time. This prevents direct collision between the base plate and the support plate, thereby greatly improving the service life of the structure. This utility model features a clamping device. When connecting tubular busbars, pulling the tension plate causes the clamping plate to move outward via the tension rod. The clamping plate compresses the spring, and then the ends of the two tubular busbars are inserted into the connecting cylinder from the extension cylinder, making the ends of the two tubular busbars connect. Then, the tension plate is released, and due to the force of the spring, the tension rod drives the clamping plate to clamp the tubular busbars. At the same time, by providing an arc-shaped silicone plate on the inner side of the clamping plate, the tubular busbars can be secured without slipping, while also protecting the surface of the tubular busbars. This invention features a cross-link device located between the buffer plate and the support plate, inside the sleeve. When the first vertical spring rebounds after absorbing shock, the oscillation force causes the outer and inner cross arms to move crosswise through the hinge shaft. At this time, the support plate will experience simple lifting and swaying, thus effectively preventing left and right swaying during shock absorption and aggravating its wear. Simultaneously, the slider will slide in the groove, and the cross-movement of the outer and inner cross arms will also dissipate the elastic force generated by the first vertical spring, thereby further achieving effective buffering and shock absorption.

[0014] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0015] According to an embodiment of the present invention, an adjustable tubular bus connector is provided.

[0016] Example 1: As shown in the attached diagram of the instruction manual. Figure 1 As shown, an adjustable tubular busbar connector includes a base plate 1, a buffer device 2, and a cross linkage device 13. An intermediate connecting element 3 is disposed above the base plate 1, and a buffer device 2 is disposed between the base plate 1 and the intermediate connecting element 3. Connecting cylinders 4 are fixedly installed on both the left and right ends of the intermediate connecting element 3. An extension cylinder 6 is movably sleeved on the other end of the connecting cylinder 4. A flange 5 is disposed on the other end of the extension cylinder 6. Fixing plates 7 are disposed on the top and bottom ends of the connecting cylinder 6. A connecting plate 8 is fixedly installed on the other end of the fixing plate 7. A fixing bolt 9 is threadedly connected to the top end of the connecting plate 8. Several threaded holes 10 are opened on the top and bottom ends of the extension cylinder 6. The several threaded holes 10 are arranged linearly from left to right. The fixing bolt 9 is threaded into the threaded hole 10 on the side near the extension cylinder 6. Sealing rings 11 are disposed on both ends of the connecting cylinder 4. The sealing rings 11 are adapted to the inner cavity of the connecting tube 4. A symmetrical clamping device 12 is disposed inside the connecting cylinder 4.

[0017] Example 2: As shown in the attached diagram of the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an adjustable tubular busbar connector is used such that, when connecting the tubular busbar, the tension plate 12.1 is first pulled. The tension plate 12.1 drives the clamping plate 12.4 to move outward through the tension rod 12.2. The clamping plate 12.4 compresses the spring 12.3. Then, the ends of the two tubular busbars are inserted into the connecting cylinder 4 from the position of the extension cylinder 6, so that the ends of the two tubular busbars are connected. Then, the tension plate 12.1 is released. Due to the force of the spring 12.3, the tension rod 12.2 drives the clamping plate 12.4 to clamp the tubular busbar. At the same time, an arc-shaped silicone plate 12.5 is provided on the inner side of the clamping plate 12.4, so that the tubular busbar can be fixed in a way that is not slippery and can also protect the surface of the tubular busbar. Then, twist the fixing bolt 9 to move one end of the fixing bolt 9 out of the threaded hole 10. Then, move the extension cylinder 6 left and right on the surface of the connecting cylinder 4 until the extension cylinder 6 is adjusted to a suitable position. Then, twist the fixing bolt 9 in the opposite direction so that one end of the fixing bolt 9 is threaded into the corresponding threaded hole 10, thereby fixing the extension cylinder 6. This allows the device to adjust its length according to actual needs, which in turn gradually increases the area supported at the end of the tubular busbar, greatly improving the stability of the tubular busbar connection.

[0018] By installing a buffer device 2 between the base plate 1 and the intermediate connecting element 3, the tubular busbar is installed inside the connecting cylinder 4. Under load, the intermediate connecting element 3 causes the support plate 2.25 to move downwards. The support plate 2.25 compresses the first vertical spring 2.22 via the guide rod 2.24. The first vertical spring 2.22 is frictionally connected to the inside of the sleeve 2.21 via the movable plate 2.23, thus achieving the first unloading of the force on the support plate 2.25. Simultaneously, the support plate 2.25 transmits the force to the first connecting rod 2.14 and the second connecting rod 2.18 via the buffer plate. The first connecting rod 2.14 and the second connecting rod 2.18 drive the first moving block 2.12 and the second moving block 2.16 to slide on the first sliding rod 2.11 and the second sliding rod 2.15 respectively, causing the first transverse spring 2.13 and the second transverse spring 2.17 to unload the force a second time. This prevents direct collision between the base plate 1 and the support plate 2.25, thereby greatly improving the service life of the structure.

[0019] A cross-link device 13 is provided between the buffer plate 2.2 and the support plate 2.25 and inside the sleeve 2.21. The oscillation force of the first vertical spring 2.22 after absorbing shock will cause the outer cross arm 13.3 and the inner cross arm 13.4 to move crosswise through the hinge shaft 13.5. At this time, the support plate 2.2 will experience simple up-and-down swaying, which effectively avoids the situation of left and right swaying during the shock absorption process and aggravating its wear. At the same time, the slider 13.2 will slide in the slide groove 13.1, and the cross-movement of the outer cross arm 13.3 and the inner cross arm 13.4 will also consume the elastic force generated by the first vertical spring 2.22, thereby further achieving effective buffering and shock absorption.
