A movable metal railing

Abstract

This utility model discloses a movable metal railing, comprising: side posts, a pair of side posts distributed left and right, with connecting posts fixed on both the upper and lower sides of the left end of the left side post, and a lock hole at the upper end of the connecting post; and a pair of connecting seats symmetrically fixed on both the upper and lower sides of the right end of the right side post. When the connecting post of an adjacent railing is inserted into the connecting slot, the arc surface at the end of the spring locking rod is compressed, and the spring locking rod automatically retracts. After the spring locking rod aligns with the lock hole, it automatically springs into the lock hole under its own rebound action to achieve initial locking. Then, by manually pushing the lever, the ratchet is no longer locked by the pawl, and the ratchet can rotate clockwise, causing the gear to rotate clockwise, thereby allowing the rack to open its spacing. This allows the spring locking rod to open its spacing and penetrate deeper into the lock hole, further reinforcing the connecting post. Combined with the moving wheels at the bottom of the side post, this makes the entire process of transporting, positioning, and quickly assembling / disassembling the railing efficient and convenient.

Description

Technical Field

[0001] This utility model relates to the field of metal railing technology, specifically a movable metal railing. Background Technology

[0002] Railings are important safety facilities in buildings. Metal railings can be reused multiple times, but sometimes it is necessary to move one end of them temporarily. Since metal railings are generally heavy, this adds a lot of trouble to moving them. Many types of metal railings generally adopt an integrated, fully welded design, with a moving component installed at the bottom to facilitate the movement of the metal railings.

[0003] Nowadays, most movable metal railings are fixed together using fasteners for easy disassembly and reuse. However, using fasteners requires not only tools to turn the fasteners but also the disassembly and reassembly of multiple fasteners, making the connection between movable metal railings quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a movable metal railing to solve the problems mentioned in the background art.

[0005] A movable metal railing includes:

[0006] Side pillars, there are a pair of side pillars and they are distributed on the left and right. The left side pillar has connecting pillars fixed on both the upper and lower sides of its left end. The upper end of the connecting pillar has a lock hole. The right side pillar has a pair of connecting seats fixed symmetrically on both the upper and lower sides of its right end. The ends of the connecting seats that are far apart from each other have connecting grooves. The connecting pillars match the connecting grooves.

[0007] The railing is fixed between the side posts;

[0008] A locking mechanism fixed between connecting seats, the locking mechanism includes a gear box, a gear rack assembly and a spring locking rod. The gear box is fixed between the connecting seats, the gear rack assembly is installed inside the gear box, and a pair of spring locking rods are symmetrically and movably inserted through the upper and lower ends of the gear box. The gear rack assembly is connected to the first end of the spring locking rod, and the end of the spring locking rod moves through the connecting groove and protrudes from the bottom of the connecting groove.

[0022] like Figures 1-3 As shown, a movable metal railing includes:

[0023] Side post 1, made of zinc alloy, is a pair of side posts 1 distributed on the left and right. The left side post 1 has connecting posts 12 fixed on both the upper and lower sides of its left end. The upper end of the connecting post 12 has a lock hole 13. The right side post 1 has a pair of connecting seats 14 symmetrically fixed on both the upper and lower sides of its right end. The ends of the connecting seats 14 that are far apart from each other have connecting grooves 15. The connecting posts 12 and connecting grooves 15 are matched. When connecting metal railings, the connecting post 12 of one metal railing is inserted into the connecting groove 15 of the connecting seat 14 of the other metal railing.

[0024] The railing 2 is fixed between the side posts 1 and is made of zinc alloy material;

[0025] A locking mechanism 3 is fixed between the connecting seats 14. The locking mechanism 3 includes a gear box 31, a gear rack assembly, and a spring locking rod 39. The gear box 31 is fixed between the connecting seats 14. The gear rack assembly is installed inside the gear box 31. There is a pair of spring locking rods 39 that move symmetrically through the upper and lower ends of the gear box 31. The gear rack assembly is connected to the head end of the spring locking rod 39. The tail end of the spring locking rod 39 moves through the inside of the connecting groove 15 and protrudes from the bottom of the connecting groove 15. The tail end of the spring locking rod 39 is an arc surface. When the connecting post 12 is inserted into the connecting groove 15, the arc surface of the tail end of the spring locking rod 39 is compressed, and the spring locking rod 39 automatically retracts. After the spring locking rod 39 is aligned with the lock hole 13, it automatically springs into the lock hole 13 under its own rebound action to achieve initial locking of the connecting post 12.

[0026] The gear and rack assembly includes a shaft 32, a gear 33, a rack 34, and a connecting rod 36. The shaft 32 is rotatably connected to the center of the gear box 31. The gear 33 is fixed to the outside of the shaft 32. A pair of racks 34 are symmetrically meshed and connected to the left and right sides of the gear 33. Each rack 34 has a slide 35 fixedly connected to its end. The head of each rack 34 abuts against the other slide 35. The connecting rod 36 is fixed to the end of the slide 35 away from the rack 34. A pressure plate 37 is fixed to the end of the connecting rod 36. A spring 38 is provided on the outside of the connecting rod 36. The head and tail of the spring 38 are respectively connected to the pressure plate 37 and the gear box 31. The head of the spring locking rod 39 is fixed to the pressure plate 37. When the shaft 32 rotates clockwise, it can drive the gear 33 to rotate clockwise. As the gear 33 meshes with the left and right racks 34... This causes the rack 34 to open up the gap, which in turn drives the slide 35 to open up the gap. Then, the slide 35 drives the connecting rod 36 to open up the gap simultaneously, and the connecting rod 36 drives the pressure plate 37 to open up the gap simultaneously. This causes the spring locking rod 39 to open up the gap simultaneously. When the shaft 32 rotates counterclockwise, it drives the gear 33 to rotate counterclockwise. As the gear 33 meshes with the left and right racks 34, the rack 34 closes up the gap. This causes the rack 34 to drive the slide 35 to close up the gap, and then the slide 35 drives the connecting rod 36 to close up the gap simultaneously. The connecting rod 36 drives the pressure plate 37 to close up the gap simultaneously. At this time, the pressure plate 37 squeezes the spring 38, causing the spring 38 to store energy, which causes the spring locking rod 39 to close up the gap simultaneously until the head of the rack 34 abuts against the other slide 35. At this time, the arc surface of the end of the spring locking rod 39 just protrudes from the bottom of the connecting groove 15.

[0027] A self-locking mechanism 4 is fixed to the front end of the gear box 31. The self-locking mechanism 4 includes a ratchet box 41, a second shaft 42, a ratchet 43, a pawl 44, and a second spring 45. The ratchet box 41 is fixed to the front end of the gear box 31. The second shaft 42 is rotatably connected to the inside of the ratchet box 41. The rear part of the second shaft 42 moves through the inside of the gear box 31 and is fixed to the first shaft 32. The front part of the second shaft 42 moves through the ratchet box 41 and is fixed with a knob 5. The ratchet 43 is fixed to the outside of the second shaft 42. The pawl 44 is located above the ratchet 43 and is rotatably connected to the inside of the ratchet box 41. The pawl 44 is connected to the ratchet 43. The second spring 45 is connected to the upper end of the pawl 44. Between the ratchet box 41 and the top of the ratchet box 41, there is a notch 47 on the right end of the ratchet box 41. A lever 46 is fixed to the right end of the pawl 44. The end of the lever 46 extends out of the notch 47. After the connecting post 12 is initially locked, the lever 46 is manually pushed to slide along the notch 47. The lever 46 drives the pawl 44 to rotate and is no longer connected to the ratchet 43. At this time, the ratchet 43 is no longer locked and can rotate clockwise. In this way, the energy storage spring 38 can drive the pressure plate 37 to open the gap. At this time, the gear 33 can rotate clockwise, so that the spring locking rod 39 can open the gap and further penetrate into the lock hole 13 to further reinforce the connecting post 12 and prevent the connecting post 12 from separating from the connecting seat 14.

[0028] When it is necessary to disassemble the two metal railings, turn knob 5 counterclockwise. Knob 5 drives shaft 2 42 to rotate counterclockwise. Shaft 2 42 drives ratchet 43 to rotate counterclockwise, and at the same time, it also drives shaft 1 32 to rotate counterclockwise. Shaft 1 32 drives gear 33 to rotate counterclockwise. As gear 33 meshes with the left and right racks 34, the racks 34 are brought closer together. In this way, racks 34 can drive slide 35 to bring the distance closer. Then slide 35 drives connecting rod 36 to bring the distance closer simultaneously. Connecting rod 36 drives pressure plate 37 to bring the distance closer simultaneously. At this time, pressure plate 37 compresses spring 1 38, causing spring 1 38 to store energy, thereby causing spring locking rod 39 to bring the distance closer simultaneously. The rack 34 continues to move until its tip abuts against another slide 35. At this point, the arc surface at the end of the spring locking rod 39 protrudes from the bottom of the connecting groove 15. Then, by forcefully pulling the two metal railings apart, the arc surface at the end of the spring locking rod 39 is compressed, causing the spring locking rod 39 to automatically retract. Since the tip of the rack 34 abuts against another slide 35, the rack 34 is prevented from moving further. Therefore, the spring 38 is not compressed at this point, and the spring locking rod 39 itself provides elasticity. This allows the two metal railings to be pulled until the connecting post 12 moves out of the connecting groove 15. This makes the entire process of transporting, positioning, and quickly disassembling the metal railings efficient and convenient, greatly improving the turnover efficiency.

[0029] The ratchet box 41 has a drain hole 48 at the lower end. When water enters the ratchet box 41 through the notch 47, the water can be drained through the drain hole 48 to prevent water accumulation inside the ratchet box 41. The ratchet 43 and pawl 44 are coated with anti-rust paint to prevent rusting.

[0030] The side post 1 is equipped with casters 11 on both the front and rear sides at the lower end. These casters 11 are brake casters, which facilitate the movement of the metal railing to a suitable position and then lock it to ensure that the metal railing remains stable in the current position.
