Description

Technical Field

[0001] The invention relates to the technical field of pole-mounted distribution boxes, and in particular to a pole-mounted distribution box for fire protection engineering. Background Art

[0002] The distribution box is a massive parameter in data. It is generally composed of low-voltage electrical wiring. It requires the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment to be assembled in a closed or semi-closed metal cabinet to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. The existing pole-mounted distribution boxes are mainly installed on the pole by means of pole ties and clamps.

[0003] The patent with publication number: CN210985329U discloses a pole-mounted fire protection engineering distribution box, including a mounting support plate, a connecting sleeve is fixedly installed on one side of the mounting support plate, and a rotating shaft rod is rotatably connected inside the connecting sleeve. Both ends of the rotating shaft rod pass through the connecting sleeve and extend to the outside of the connecting sleeve. The beneficial effect of the utility model is: a transfer sleeve is fixedly sleeved on the outside of the rotating shaft rod, and a plurality of connecting plugs are fixedly provided on the outside of the transfer sleeve, and the connecting plugs are engaged with the limiting slots inside the clamping steel bar, so that the clamping steel bar is tightened by rotating the transfer sleeve, so that the mounting support plate can be fixed on the outside of the cylindrical rod, and the limiting clamping plate is rotatably connected to the inside of the transfer sleeve by the transfer rod, so as to realize the position clamping of the sliding support plate, so that the clamping block on one side of the arc groove contacts the connecting plug, thereby realizing the fixed installation of the mounting support plate.

[0004] However, there are still some shortcomings in the actual use of the above: 1. In order to adapt to diameters of various sizes, a bunch of holes and grooves are usually opened on the clamping steel bars, but the clamping steel bars where the holes and grooves are opened are very easy to break and are very fragile; 2. After installation, the distribution box often needs to be adjusted in various ways due to the different diameters of different poles, which makes the installation very inconvenient and it is very easy to have gaps, making the installation not firm enough.

[0045] Among them, the clamping mechanism 303 includes a first knob 5, a fixed plate 14, a first shaft 19, a second shaft 20, a fourth gear 25, a connecting base 16, two clamping rods 15 and two first racks 29, the first shaft 19 is rotatably connected to the inner wall of the first slider 4, the fixed plate 14 is rotatably connected to the bottom outer wall of the first slider 4, the second shaft 20 is slidably connected to the inner wall of the first shaft 19, the fourth gear 25 is fixedly connected to the end of the second shaft 20, the two first racks 29 are meshed with the outer wall of the fourth gear 25, the two first racks 29 are slidably connected to the fixed plate 14, the two clamping rods 15 are respectively fixedly connected to the first racks 29, and the connecting base 16 is slidably connected to the two clamping rods 15.

[0046] In this embodiment, the steel belt 2 is wrapped around the rod, the end of the steel belt 2 is inserted into the mounting seat 9 through the auxiliary inclined plate 10, and the steel belt 2 is placed between the two clamping rods 15. Then, an installation tool (such as an impact drill) is used to insert it into the first knob 5 and rotate it, so that the first knob 5 drives the fourth gear 25 to rotate through the second shaft rod 20. The rotation of the fourth gear 25 drives the two clamping rods 15 to approach each other through the first rack 29 to clamp the steel belt 2. The two clamping rods 15 move to a mutually staggered position, causing the steel belt 2 to deform, thereby enhancing the resistance between the steel belt 2 and the clamping rod 15, so that the steel belt 2 will not easily detach from the clamping rod 15.

[0047] Among them, the anti-slip mechanism 404 includes a second rack 30, a third gear 23, a third shaft rod 31 and a first bevel gear 32. The second rack 30 is fixedly connected to the fixed plate 2 14, the third gear 23 is fixedly connected to the third shaft rod 31, the first bevel gear 32 is fixedly connected to the third shaft rod 31, and the third shaft rod 31 is fixedly connected to the inner wall of the clamping rod 15. Two anti-slip mechanisms 404 are provided, and the two anti-slip mechanisms 404 are distributed in a circular array. The inner walls of the two clamping rods 15 are slidably connected with a plurality of conical locking rods 36, the inner wall of each conical locking rod 36 is threadedly connected with a second threaded rod 38, and the end of each second threaded rod 38 is fixedly connected with a transmission gear 1 35, and the outer walls of several adjacent transmission gears 1 35 are sleeved with the same first chain 34, wherein the outer walls of the two transmission gears 1 35 are fixedly connected with the second bevel gears 33, and the two second bevel gears 33 are respectively meshed with the two first bevel gears 32.

[0048] In this embodiment, when the two clamping rods 15 approach each other, the third gear 23 moves along the second rack 30, the third gear 23 will drive the first bevel gear 32 to rotate through the third shaft rod 31, the first bevel gear 32 drives the first chain 34 to rotate through the second bevel gear 33, and the first chain 34 drives all the second threaded rods 38 to rotate through the transmission gear 1 35, so that the conical locking rod 36 will extend along the clamping rod 15, thereby embedding into the interior of the steel belt 2, further making the surface of the steel belt 2 have some potholes, increasing the resistance between the steel belt 2 and the clamping rod 15, ensuring the stability of the connection between the steel belt 2 and the clamping rod 15, and the fixing plate 2 14 is restricted by the mounting seat 9, so the fixing plate 2 14 will not rotate.

[0049] Among them, the connection switching mechanism 101 includes a limiting wheel 22, a limiting plate 21 and four first springs 24, the limiting wheel 22 is fixedly connected to the second shaft rod 20, the limiting plate 21 is fixedly connected to the limiting wheel 22, and the four first springs 24 are fixedly connected between the first shaft rod 19 and the limiting plate 21.

[0050] Among them, the clamping and locking mechanism 202 includes a limiting ring 26, four inclined slides 27 and four clamping plates 28. The limiting ring 26 is connected to the first shaft 19 through a one-way bearing. The four inclined slides 27 are slidably connected to the inner wall of the limiting ring 26. The four clamping plates 28 are respectively fixedly connected to the inclined slides 27. The four clamping plates 28 are respectively slidably connected to the inner wall of the fixed plate 2 14.

[0051] In this embodiment, a tool is then used to rotate the second knob 8 so that the second slider 6 drives the first slider 4 and the clamping rod 15 to pull the steel belt 2 to move. When the first slider 4 moves to the top of the locking seat 11, the limiting plate 3 gradually becomes narrower, so the first knob 5 moves down at this time, and the first knob 5 drives the first shaft rod 19 to move down. The limiting ring 26 squeezes the inclined slide plate 27, so that the clamping plate 28 forms a limit on the four sides of the fourth gear 25. At this time, the first knob 5 is rotated in the opposite direction, and the limiting ring 26 is resisted by the one-way bearing, and the fixed plate 2 14 is separated from the limit of the mounting seat 9. Therefore, at this time, the fixed plate 2 14 drives the clamping rod 15 to rewind the steel belt 2, so that the steel belt 2 is circled around the outer wall of the clamping rod 15. At this time, the first gear 17 is meshed with the baffle 40, and the second gear 18 is meshed with the fifth gear 39.

[0052] Among them, the one-way fixing mechanism 606 includes a second gear 18, a first gear 17 and a plurality of baffles 40, the second gear 18 is fixedly connected to the connecting base 16, the second gear 18 and the first gear 17 are connected by a one-way bearing, and the plurality of baffles 40 are fixedly connected to the inner wall of the locking seat 11.

[0053] Among them, the supplement mechanism 505 includes a fifth gear 39, a belt 44, a fourth shaft 45, a fourth bevel gear 42, a third bevel gear 41, a second chain 43, an extrusion cam 46, an elastic airbag 47, two transmission gears 49, two ventilation pipes 48, two filling plates 13 and two inflatable airbags 37, the fifth gear 39 is rotatably connected to the outer wall of the locking seat 11, the fifth gear 39 is movably connected to the inner wall of the belt 44 through the set shaft, the other end of the belt 44 is movably connected to the outer wall of the fourth shaft 45, the fourth bevel gear 42 is fixedly connected to the fourth shaft 45, and the third The outer wall of the bevel gear 41 is meshed with the fourth bevel gear 42, the two transmission gears 49 are fixedly connected to the third bevel gear 41 and the extrusion cam 46 respectively, the second chain 43 is sleeved on the outer walls of the two transmission gears 49, the elastic airbag 47 is arranged below the extrusion cam 46, and the two sides of the elastic airbag 47 are connected with ventilation pipes 48, the elastic airbag 47 is fixedly connected to the inner wall of the mounting seat 9, the ends of the two ventilation pipes 48 are fixedly connected to the inflatable airbags 37, the outer walls of the two inflatable airbags 37 are fixedly connected to the filling plates 13, and the filling plates 13 are slidably connected to the inner wall of the mounting seat 9.

[0054] In this embodiment, when the steel strip 2 is wound, the first gear 17 is subjected to the force of the one-way gear, so the first gear 17 is relatively stationary with the locking seat 11 at this time, but the first gear 17 and the second gear 18 rotate relatively, and at the same time the second gear 18 is meshed with the fifth gear 39, and the fifth gear 39 drives the fourth shaft rod 45 to rotate through the belt 44, and the fourth shaft rod 45 drives the third bevel gear 41 to rotate through the fourth bevel gear 42, and the third bevel gear 41 rotates through the transmission gear 2 49 and the second chain 43, and the extrusion cam 46 continuously squeezes the elastic airbag 47, so that the elastic airbag 47 refuels the inflated airbag 37, so that the filling plate 13 extends out to fill the gap between the steel strip 2 and the distribution box body 1 and the rod. Since the first gear 17 and the second gear 18 are connected by a one-way bearing, the first gear 17 is stuck by the baffle 40, and the entire clamping rod 15 cannot rotate, completing the final fixation, and there is no need to open a hole groove on the outer wall of the steel strip 2 to adapt to any diameter of the rod.

[0055] The specific working principle and method of use of the present invention are explained in detail below: when in use, the steel belt 2 is wrapped around the rod, the end of the steel belt 2 is inserted into the mounting seat 9 through the auxiliary inclined plate 10, and the steel belt 2 is placed between the two clamping rods 15. Then, an installation tool (such as an impact drill) is used to insert it into the first knob 5 and rotate it, so that the first knob 5 drives the fourth gear 25 to rotate through the second shaft rod 20. The rotation of the fourth gear 25 drives the two clamping rods 15 to approach each other through the first rack 29 to clamp the steel belt 2. The two clamping rods 15 move to a mutually staggered position, causing the steel belt 2 to deform, thereby enhancing the resistance between the steel belt 2 and the clamping rod 15, so that the steel belt 2 will not easily detach from the clamping rod 15.

[0056] At the same time, when the two clamping rods 15 approach each other and the third gear 23 moves along the second rack 30, the third gear 23 will drive the first bevel gear 32 to rotate through the third shaft rod 31, the first bevel gear 32 will drive the first chain 34 to rotate through the second bevel gear 33, and the first chain 34 will drive all the second threaded rods 38 to rotate through the transmission gear 1 35, so that the conical locking rod 36 will extend along the clamping rod 15, thereby embedding into the interior of the steel belt 2, further making some potholes on the surface of the steel belt 2, increasing the resistance between the steel belt 2 and the clamping rod 15, ensuring the stability of the connection between the steel belt 2 and the clamping rod 15, and the fixing plate 2 14 is restricted by the mounting seat 9, so the fixing plate 2 14 will not rotate.

[0057] Then, a tool is used to rotate the second knob 8 so that the second slider 6 drives the first slider 4 and the clamping rod 15 to pull the steel belt 2 to move. When the first slider 4 moves to the top of the locking seat 11, since the limit plate 3 gradually becomes narrower, the first knob 5 moves down at this time, and the first knob 5 drives the first shaft rod 19 to move down. The limit ring 26 squeezes the inclined slide plate 27, so that the clamping plate 28 forms a limit on the four sides of the fourth gear 25. At this time, the first knob 5 is rotated in the opposite direction, and the limit ring 26 is resisted by the one-way bearing, and the fixed plate 2 14 is separated from the limit of the mounting seat 9. Therefore, the fixed plate 2 14 drives the clamping rod 15 to rewind the steel belt 2, so that the steel belt 2 is circled around the outer wall of the clamping rod 15. At this time, the first gear 17 is meshed with the baffle 40, and the second gear 18 is meshed with the fifth gear 39.

[0058] When the steel strip 2 is wound up, the first gear 17 is subjected to the force of the one-way gear, so the first gear 17 is relatively stationary with the locking seat 11 at this time, but the first gear 17 and the second gear 18 rotate relatively, and at the same time, the second gear 18 is meshed with the fifth gear 39, and the fifth gear 39 drives the fourth shaft rod 45 to rotate through the belt 44, and the fourth shaft rod 45 drives the third bevel gear 41 to rotate through the fourth bevel gear 42, and the third bevel gear 41 rotates through the transmission gear 2 49 and the second chain 43, and the extrusion cam 46 continuously squeezes the elastic airbag 47, so that the elastic airbag 47 refuels the inflated airbag 37, so that the filling plate 13 extends out to fill the gap between the steel strip 2 and the distribution box body 1 and the rod. Since the first gear 17 and the second gear 18 are connected by a one-way bearing, the first gear 17 is stuck by the baffle 40, and the entire clamping rod 15 cannot rotate, completing the final fixation, and there is no need to open a hole groove on the outer wall of the steel strip 2 to adapt to any diameter of the rod.

[0059] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
