[0001] The utility model relates to the technical field of bus ducts, in particular to a compact and dense bus duct. Background Art

[0002] In the prior art, such as a compact and dense bus duct with the publication number of CN218919921U disclosed on the Chinese patent website, although the utility model device solves the problem that the existing bus duct lacks a compact structure and a side protection structure design, which easily increases potential safety hazards on both sides during use, the following problems still exist in the actual use process:

[0003] After installing the compact and dense bus duct, in order to prevent it from shaking, it is necessary to fix it with multiple bolts. In this way, when the bus duct is damaged and needs to be repaired, specific types of disassembly tools need to be found for disassembly and installation operations, which greatly reduces the replacement efficiency and has poor practicability. Summary of the Utility Model

[0004] Based on the technical problems that the existing bus duct requires specific types of disassembly tools for disassembly and installation operations, with low replacement efficiency and poor practicability, the utility model provides a compact and dense bus duct.

[0005] The compact and dense bus duct provided by the utility model includes a conductive bar, both ends of the conductive bar are fixedly connected with conductive bus bars, an insulating rubber block is fixedly installed on the outer surface of the conductive bar, a protective shell is in extrusion contact with the outer surfaces of multiple insulating rubber blocks, contact blocks are respectively fixedly installed on the upper and lower parts of the protective shell, the opposite surfaces of two contact blocks on the same side are in extrusion contact, quick-release fixing mechanisms are arranged on both sides of the contact blocks, and some of the quick-release fixing mechanisms are arranged in the opposite direction, and the quick-release fixing mechanisms realize the quick disassembly and installation actions of the protective shell.

[0006] Preferably, the quick-release fixing mechanism includes a mounting block, the mounting block is fixedly installed on one side surface of the contact block, a sliding groove is formed on the surface of the mounting block, a cylindrical sliding block is slidably inserted into the inner side wall of the sliding groove, the opposite surfaces of two cylindrical sliding blocks are fixedly connected with a U-shaped fixing block, the two side surfaces of the U-shaped fixing block are respectively slidably inserted into the opposite surfaces of two mounting blocks, and the inner side surface of the U-shaped fixing block is in extrusion contact with the surfaces of two contact blocks.

[0007] Through the above technical solution, a U-shaped fixing block and a chute are provided. The cylindrical sliders on both sides of one end of the U-shaped fixing block are slidably inserted into the chute, so that the up and down movement of the U-shaped fixing block is restricted by the chute, and the U-shaped fixing block can rotate around the cylindrical slider. Moving the U-shaped fixing block downward can squeeze and fix the contact block. After pulling the U-shaped fixing block upward and rotating it, the extrusion fixation of the contact block by the U-shaped fixing block can be released, enabling the protective housing to be conveniently installed and disassembled.

[0008] Preferably, a fixing block is fixedly installed on one side surface of the contact block. A limiting groove is formed on the upper surface of the fixing block, and a limiting hole is also formed on one side surface of the fixing block. An L-shaped limiting block is slidably inserted into the opposite inner surfaces of the limiting groove. The end side surface of the L-shaped limiting block is slidably inserted into the inner wall of the limiting hole. The lower end of the L-shaped limiting block extends outside the limiting hole, and the lower surface of the end of the L-shaped limiting block extending out of the limiting hole is in pressing contact with the arc surface of the cylindrical slider.

[0009] Through the above technical solution, the L-shaped limiting block is provided. When the U-shaped fixing block squeezes and fixes the contact block, the cylindrical slider will move to the bottom end of the chute, and the lower surface of the end side of the L-shaped limiting block is in pressing contact with the cylindrical slider, fixing the cylindrical slider at the bottom end of the chute and also fixing the position of the U-shaped fixing block, realizing the fixation of the protective housings on both sides. When the protective housing needs to be disassembled, push the L-shaped limiting block to make the L-shaped limiting block slide along the limiting groove and slide into the limiting hole, releasing the pressing contact with the cylindrical slider, enabling the cylindrical slider to move in the chute and the U-shaped fixing block to move upward without restriction, thus releasing the fixation of the protective housings on both sides and disassembling the protective housing.

[0010] Preferably, limiting rods are also fixedly connected to the opposite inner surfaces of the limiting groove. The arc surfaces of the plurality of limiting rods are all slidably inserted into the surface of the L-shaped limiting block. A limiting spring is fixedly connected to the inner wall of the limiting groove. One end of each of the plurality of limiting springs is fixedly connected to one side surface of the L-shaped limiting block. The limiting spring is wound around the outer surface of the limiting rod, and the upper surface of one end of the L-shaped limiting block is provided as an inclined surface.

[0011] Through the above technical solution, a limiting rod is provided to limit the sliding of the L-shaped limiting block in the limiting groove and move it as required. A limiting spring is provided to enable the L-shaped limiting block to always be at one end of the limiting groove without human interference, so that the L-shaped limiting block always limits and fixes the cylindrical slider, realizing the fixation of the U-shaped fixing block to the protective housing. The upper surface of one end of the L-shaped limiting block is set as an inclined surface. When installing the protective housing, the U-shaped fixing block needs to be moved downward, which will cause the cylindrical slider to contact the upper surface of one end of the L-shaped limiting block. When the upper surface of one end of the L-shaped limiting block is set as an inclined surface, the downward movement of the cylindrical slider will squeeze the inclined surface, causing the L-shaped limiting block to move inward and not block the downward movement of the cylindrical slider. Finally, when the cylindrical slider moves down to the bottom, the L-shaped limiting block will return to its original position under the action of the limiting spring, and the lower surface of one end of the L-shaped limiting block will limit and fix the cylindrical slider.

[0012] Preferably, a limiting block is further fixedly installed on the outer surface of the contact block, and the opposite surfaces of the two limiting blocks are slidably inserted into the side surface of one end of the U-shaped fixing block.

[0013] Through the above technical solution, the limiting block is provided to limit the U-shaped fixing block and prevent the protective housing from sliding left and right at the same time.

[0014] Preferably, T-shaped grooves are further opened on the two end surfaces of the protective housing, and a protective plate is slidably inserted into the inner side wall of the T-shaped groove.

[0015] Through the above technical solution, the protective plate is provided to protect the conductive busbar.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. By providing an insulating rubber block, the conductive row is isolated from the protective housing to prevent the protective housing from being electrified. A quick-release fixing structure is provided to facilitate the quick installation and disassembly of the two protective housings, and every two adjacent quick-release fixing mechanisms are arranged in the reverse direction, making the fixation of the quick-release fixing mechanism to the two protective housings more stable, solving the technical problems that the existing busbar is difficult to disassemble and install, requires a specific type of disassembly tool for operation, has low replacement efficiency, and poor practicability.

[0018] 2. By setting the upper surface of one end of the L-shaped limiting block as an inclined surface, when installing the protective housing, the U-shaped fixing block needs to be moved downward, which will cause the cylindrical slider to contact the upper surface of one end of the L-shaped limiting block. When the upper surface of one end of the L-shaped limiting block is set as an inclined surface, the downward movement of the cylindrical slider will squeeze the inclined surface, causing the L-shaped limiting block to move inward and not block the downward movement of the cylindrical slider. Finally, when the cylindrical slider moves down to the bottom, the L-shaped limiting block will return to its original position under the action of the limiting spring, and the lower surface of one end of the L-shaped limiting block will limit and fix the cylindrical slider.

Specific embodiments

[0026] 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 of the embodiments.

[0027] Refer to Figures 1-6 , a compact and dense busbar groove, including a conductive bar 1, conductive busbars 2 are fixedly connected to both ends of the conductive bar 1, an insulating rubber block 3 is fixedly installed on the outer surface of the conductive bar 1, a protective housing 4 is in extrusion contact with the outer surfaces of a plurality of insulating rubber blocks 3, contact blocks 5 are fixedly installed on the upper and lower parts of the protective housing 4 respectively, the opposite surfaces of two contact blocks 5 on the same side are in extrusion contact, quick-release fixing mechanisms are arranged on both sides of the contact block 5, and part of the quick-release fixing mechanisms are arranged in the opposite direction, and the quick-release fixing mechanisms realize the quick disassembly and installation actions of the protective housing 4.

[0028] In order to install and disassemble the protective housing 4 quickly and conveniently, a quick-release fixing mechanism is provided. The quick-release fixing mechanism includes an installation block 6, which is fixedly installed on one side surface of the contact block 5. A chute 7 is formed on the surface of the installation block 6. A cylindrical slider 8 is slidably inserted into the inner side wall of the chute 7. Opposite surfaces of the two cylindrical sliders 8 are fixedly connected with U-shaped fixing blocks 9. The two side surfaces of the U-shaped fixing blocks 9 are respectively slidably inserted into the opposite surfaces of the two installation blocks 6. The inner side surface of the U-shaped fixing blocks 9 is in pressing contact with the surfaces of the two contact blocks 5.

[0029] By providing the U-shaped fixing block 9 and the chute 7, the cylindrical sliders 8 on both ends of one end of the U-shaped fixing block 9 are slidably inserted into the chute 7, so that the up and down movement of the U-shaped fixing block 9 is restricted by the chute 7, and the U-shaped fixing block 9 can rotate around the cylindrical slider 8. Moving the U-shaped fixing block 9 downward can press and fix the contact block 5. After pulling the U-shaped fixing block 9 upward and rotating it, the extrusion fixation of the U-shaped fixing block 9 on the contact block 5 can be released, enabling the convenient installation and disassembly of the protective housing 4.

[0030] In order to stably limit and fix the position of the U-shaped fixing block 9, a fixing block 10 is fixedly installed on one side surface of the contact block 5. A limiting groove 11 is formed on the upper surface of the fixing block 10. A limiting hole 12 is also formed on one side surface of the fixing block 10. An L-shaped limiting block 13 is slidably inserted into the opposite inner surfaces of the limiting groove 11. The end side surface of the L-shaped limiting block 13 is slidably inserted into the inner side wall of the limiting hole 12. The lower end of the L-shaped limiting block 13 extends outside the limiting hole 12. The end side lower surface of the L-shaped limiting block 13 is in pressing contact with the arc surface of the cylindrical slider 8.

[0031] By providing the L-shaped limiting block 13, when the U-shaped fixing block 9 presses and fixes the contact block 5, the cylindrical slider 8 will move to the bottom end of the chute 7, and the end side lower surface of the L-shaped limiting block 13 is in pressing contact with the cylindrical slider 8, fixing the cylindrical slider 8 at the bottom end of the chute 7 and also fixing the position of the U-shaped fixing block 9, realizing the fixation of the two-sided protective housing 4. When it is necessary to disassemble the protective housing 4, push the L-shaped limiting block 13 to make the L-shaped limiting block 13 slide along the limiting groove 11 and slide into the limiting hole 12, releasing the pressing contact with the cylindrical slider 8, enabling the cylindrical slider 8 to move in the chute 7, making the upward movement of the U-shaped fixing block 9 unrestricted, and then the fixation of the two-sided protective housing 4 can be released to disassemble the protective housing 4.

[0032] In order to enable the L-shaped limit block 13 to stably limit and fix the cylindrical slider 8 without interference, limit rods 14 are fixedly connected to the opposite inner surfaces of the limit groove 11. The arc surfaces of the plurality of limit rods 14 are all slidably inserted into the surface of the L-shaped limit block 13. A limit spring 15 is fixedly connected to the inner side wall of the limit groove 11. One ends of the plurality of limit springs 15 are fixedly connected to one side surface of the L-shaped limit block 13. The limit spring 15 is wound around the outer surface of the limit rod 14. The upper surface of one end of the L-shaped limit block 13 is set as an inclined surface.

[0033] By providing the limit rods 14, the sliding of the L-shaped limit block 13 in the limit groove 11 is restricted by the limit rods 14 and moves according to requirements. The limit springs 15 are provided so that the L-shaped limit block 13 can always be at one end of the limit groove 11 without human interference, enabling the L-shaped limit block 13 to always limit and fix the cylindrical slider 8, thus realizing the fixation of the U-shaped fixing block 9 to the protective housing 4. The upper surface of one end of the L-shaped limit block 13 is set as an inclined surface. When installing the protective housing 4, the U-shaped fixing block 9 needs to be moved downward, causing the cylindrical slider 8 to contact the upper surface of one end of the L-shaped limit block 13. When the upper surface of one end of the L-shaped limit block 13 is set as an inclined surface, the downward movement of the cylindrical slider 8 will squeeze the inclined surface, causing the L-shaped limit block 13 to move inward and not block the downward movement of the cylindrical slider 8. Finally, when the cylindrical slider 8 moves down to the bottom, the L-shaped limit block 13 will return to its original position under the action of the limit spring 15, enabling the lower surface of one end of the L-shaped limit block 13 to limit and fix the cylindrical slider 8.

[0034] To prevent the protective housing 4 from sliding left and right, limit blocks 16 are also fixedly installed on the outer surface of the contact block 5. The opposite surfaces of the two limit blocks 16 are also slidably inserted into the side surface of one end of the U-shaped fixing block 9. To protect the conductive busbar 2, T-shaped grooves 17 are also opened on the two end surfaces of the protective housing 4. Protective plates 18 are slidably inserted into the inner side walls of the T-shaped grooves 17. By providing the limit blocks 16, the U-shaped fixing block 9 is limited, and at the same time, the left and right sliding of the protective housing 4 is prevented. By providing the protective plates 18, the conductive busbar 2 is protected.

[0035] Working principle: During installation, the two protective shells 4 are respectively installed on the outside of the busbar 1 from the front side and the rear side, so that the two contact blocks 5 are pressed against each other in contact, and the positions of the U-shaped fixing blocks 9 are corresponding to the positions of the limit blocks 16. Rotate the U-shaped fixing blocks 9 so that the inner sides of the U-shaped fixing blocks 9 are parallel to the upper surfaces of the contact blocks 5. Press the U-shaped fixing blocks 9 to move them downward, driving the cylindrical sliders 8 to slide downward in the sliding grooves 7, so that the cylindrical sliders 8 move downward to press the inclined surfaces on the L-shaped limit blocks 13, causing the L-shaped limit blocks 13 to slide inward, so that the L-shaped limit blocks 13 do not block the downward movement of the cylindrical sliders 8. When the cylindrical sliders 8 move downward to the bottom, the L-shaped limit blocks 13 will return to their original positions under the action of the limit springs 15, so that the lower surfaces of one ends of the L-shaped limit blocks 13 limit and fix the cylindrical sliders 8, fixing the U-shaped fixing blocks 9. At the same time, the limit blocks 16 limit the U-shaped fixing blocks 9 to prevent the protective shells 4 from sliding left and right. When disassembly is required, the staff pushes the L-shaped limit blocks 13 to release the limit and fixation of the lower surfaces of the L-shaped limit blocks 13 on the cylindrical fixing blocks 10, and then the U-shaped fixing blocks 9 can be pulled upward to release the fixation of the U-shaped fixing blocks 9 on the protective shells 4, facilitating the disassembly of the protective shells 4.

[0036] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
