[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0020] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0021] See also Figures 1 to 12 , an embodiment of the present invention provides a quick-connect bus duct connection structure, the quick-connect bus duct connection structure includes a bus duct body 1, a side connecting plate 2, a top connecting plate 5, a locking assembly 3 and an elastic support member 4; The top of the bus duct body 1 is welded and fixed with a first threaded rod 11 , while the side is welded and fixed with a second threaded rod 12 .
[0022] For the side connecting plate 2 and the locking assembly 3; See also Figures 5 to 10 The side connecting plate 2 includes a first plate body 21, both ends of the first plate body 21 are welded with a positioning plate 22, the other side of the positioning plate 22 is welded with a positioning rod 23, and the other end of the positioning rod 23 is welded with a hook-shaped locking block 24; Two horizontally arranged second supporting plates 26 are symmetrically welded and fixed on one side of the first plate 21 and away from the center. A third threaded rod 27 is welded and fixed on one side of the second supporting plate 26. Two horizontally arranged first supporting plates 25 are symmetrically welded and fixed to the other side of the first plate body 21 and away from the center. The ends of the first supporting plates 25 abut against the bus duct body 1. A first reinforcing plate 28 is also welded and fixed to the same side of the first plate body 21. The two sections of the first reinforcing plate 28 are welded and fixed to the positioning plate 22. See also Figures 1 to 3 The locking assembly 3 includes a base 31, which is attached to one side of the bus duct body 1, and the second threaded rod 12 passes through the base 31 and is fixed by a nut. A cover plate 32 is bolted to one side of the base 31, and a closed container space is formed between the base 31 and the cover plate 32. A socket 33 is also opened on one side of the base 31, and the locking block 24 can be inserted into the container space along the socket 33; A rotating shaft 34 is rotatably connected to the base 31. A gear 35 is fixed to the rotating shaft 34 and is concentrically arranged and located inside the container space. A torsion spring 36 is also sleeved on the rotating shaft 34. One end of the torsion spring 36 presses against the base 31 and the other end presses against the gear 35. One end of the rotating shaft 34 also passes through the cover 32 and is fixed to a turning handle 37. A positioning seat 38 is bolted to one side of the base 31, and a slide groove 39 is provided on one side of the positioning seat 38. A slider 310 is slidably connected inside the slide groove 39. A transmission plate 311 is welded and fixed to the other side of the slider 310. A tooth plate 312 meshing with the gear 35 is welded and fixed to one side of the transmission plate 311, and a bite block 313 is integrally connected to one end.
[0023] It should be noted that: in the side connecting plate 2, the first plate body 21 is used as the basic plate, and both ends of the first plate body 21 have positioning plates 22. A positioning rod 23 is welded to the other side of the positioning plate 22, and a hook-shaped locking block 24 is provided at the other end of the positioning rod 23. In the locking assembly 3, a storage space is formed between the base 31 and the cover plate 32. A socket 33 is provided on one side of the base 31, that is, the positioning rod 23 and the locking block 24 can be inserted into the storage space along the socket 33. At the same time, a movable transmission plate 311 is provided inside the storage space, and a bite block 313 is provided at one end of the transmission plate 311. The bite block 313 can be engaged with the locking block 24, so that the locking block 24 can be locked to achieve the connection between the first plate body 21 and the locking assembly 3. The base 31 in the locking assembly 3 is fixed to the bus duct body 1. Therefore, the first plate body 21 can be used as a connecting plate to achieve the connection between the two sections of the bus duct body 1. The transmission plate 311 has a slider 310 on one side, and the slider 310 is slidably connected to the inside of the slide groove 39, and the positioning seat 38 is bolted to the base 31, thereby realizing the installation and positioning of the transmission plate 311. At the same time, a tooth plate 312 is also provided on one side of the transmission plate 311, and a gear 35 is provided on the rotating shaft 34 installed on the base 31. The gear 35 is engaged with the tooth plate 312. Therefore, when the gear 35 rotates, it can generate a force on the tooth plate 312 to drive the two sets of transmission plates 311 to move symmetrically. At the same time, the rotating shaft 34 is subjected to the elastic force of the torsion spring 36 Therefore, when the locking block 24 is inserted, the locking block 24 will first come into contact with the bite block 313 (the contact surfaces of both are inclined surfaces), and in the process of continuous feeding, the bite block 313 will generate a force to cause the transmission plate 311 to move until the locking block 24 completely exceeds the bite block 313. Then, under the elastic force of the torsion spring 36, the driving shaft 34 rotates in the opposite direction. At this time, the gear 35 is used to drive the two sets of transmission plates 311 to move in the opposite direction, so that the bite block 313 can be embedded in the corner groove of the locking block 24, thereby being able to bite and fix the locking block 24. One end of the rotating shaft 34 passes through the cover plate 32 and is fixed with a turning handle 37. Therefore, the turning handle 37 can directly drive the rotating shaft 34 to rotate, and the gear 35 drives the two sets of transmission plates 311 to move, thereby realizing manual adjustment of the locking assembly 3, so that the bite block 313 removes the restriction of the locking block 24, and the side connecting plate 2 can be removed from the locking assembly 3. A first support plate 25 and a first reinforcement plate 28 are also provided on the first plate body 21. The first support plate 25 can enhance the connection stability with the bus duct body 1, while the first reinforcement plate 28 can make the first plate body 21 have higher pressure resistance, thereby improving the safety of the device.
[0024] For the top connecting plate 5; See also Figure 12 The top connecting plate 5 includes a second plate body 51 and a third plate body 52. The second plate body 51 and the third plate body 52 are welded and fixed and arranged in a Z shape. A second reinforcing plate 53 is also welded and fixed to one side of the second plate body 51. Both ends of the second reinforcing plate 53 are welded and fixed to the third plate body 52. Among them, the second plate body 51 of the two top connecting plates 5 is mounted on the second support plate 26, and the third threaded rod 27 passes through the second plate body 51 and is fixed by a nut; the third plate body 52 of the two top connecting plates 5 is respectively mounted on the top and bottom of the bus duct body 1, and the first threaded rod 11 passes through the third plate body 52 and is fixed by a nut.
[0025] It should be noted that: the top connecting plate 5 has a second plate body 51 and a third plate body 52, and the second plate body 51 and the third plate body 52 are Z-shaped to adapt to the bus duct body 1 and the side connecting plate 2, that is, the second plate body 51 can be mounted on the second supporting plate 26, and the third plate body 52 can be mounted on the bus duct body 1, and a first threaded rod 11 is provided on the bus duct body 1, and a third threaded rod 27 is provided on the second supporting plate 26. The first threaded rod 11 can pass through the third plate body 52 and then be reinforced with a nut, so as to achieve a stable connection between it and the bus duct body 1, and the third threaded rod 27 can pass through the second plate body 51 and then be reinforced with a nut, so as to achieve a stable connection between it and the side connecting plate 2, and at the same time, the frame composed of the side connecting plate 2 and the top connecting plate 5 can have higher stability, so it will be safer when used; It should also be noted that: for the side connecting plate 2 and the top connecting plate 5, the two have a total of four plates, and the four plates can form a U-shaped frame to achieve connection with the bus duct body 1. At the same time, when assembling the frame and installing the bus duct body 1, the two first plates 21 can be installed first, and the preliminary installation of the bus duct body 1 is achieved. When the two second plates 51 are installed, it can provide the staff with a better observation field of view, improve the installation accuracy of the bus duct body 1, and after completing the adjustment and fixation of the contacts in the bus duct body 1, the second plate 51 is installed to achieve reinforcement of the entire connection structure.
[0026] For the elastic support member 4; See also Figure 11 The elastic support member 4 includes an arc-shaped spring sheet 41, which is bolted to one side of the base 31. A pressure block 42 is welded and fixed at both ends of the spring sheet 41, and the pressure block 42 can contact and squeeze the positioning plate 22.
[0027] It should be noted that: in the elastic support member 4, the spring sheet 41 is arc-shaped and is fixed to one side of the base 31. There are cylindrical pressure blocks 42 at both ends of the spring sheet 41. Therefore, when the opposite connecting plate 2 and the locking assembly 3 are assembled, the pressure block 42 can directly contact the positioning plate 22, and when the locking block 24 and the bite block 313 are in a snap-fit state, the pressure block 42 can generate an elastic force on the positioning plate 22. The elastic force can be used to limit the locking block 24 and the bite block 313, making the contact between the two more compact. At the same time, the setting of the spring sheet 41 can also play a buffering role, thereby providing better protection for the connection area.
[0028] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
