A galvanized sheet air pipe quick assembling device

Abstract

This utility model discloses a quick assembly device for galvanized steel sheet ducts, relating to the field of mechanical engineering technology. The device includes a support base and two sliding seats. Each sliding seat has two limiting components, each including a movable seat and a clamping block. The upper surface of the movable seat has two first T-shaped block slots, and the lower surface of the clamping block is fixedly connected to two first T-shaped blocks. By rotating a threaded sleeve within the limiting component, which is threadedly engaged with a rotating threaded rod, the rotating threaded rod causes the limiting block to slide into the clamping block. The limiting block then exits from the limiting block slot of the movable seat, releasing the clamping block from its fixation. The clamping block can then be slidably removed from the first T-shaped block slot of the movable seat. This simple and quick disassembly of the clamping block effectively improves the maintenance and repair efficiency of the clamping block while reducing the workload of workers.

Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a rapid assembly device for galvanized sheet air ducts. Background Technology

[0002] In the fields of ventilation and air conditioning, industrial dust removal and other engineering, galvanized sheet ducts have become the core component for transporting gas due to their good corrosion resistance and economy. The efficient assembly of ducts directly affects the project cycle and system performance. The clamping components in the assembly device are the key structures for fixing the ducts, and their performance is of paramount importance. Among them, the clamping blocks, as the components that directly contact the ducts, have caused many problems due to the inconvenience of disassembly in practical applications, which has become a bottleneck restricting the development of the industry.

[0003] Currently, most galvanized sheet metal duct units use traditional fixing methods for their clamping blocks. In common bolted connection structures, the clamping blocks are fastened to the clamping arms by multiple bolts. During long-term use, these bolts are susceptible to rust due to dust and moisture corrosion. This results in a significant amount of time being spent on rust removal and loosening during disassembly. Some severely rusted bolts even exhibit stripped threads, making disassembly difficult. This not only prolongs downtime for maintenance but may also damage the clamping arms or other components due to forced disassembly. Welded clamping blocks present even greater challenges in replacement. Once a clamping block wears out and needs replacement, the welded parts must be removed through cutting and grinding, which is not only complex and inefficient but may also compromise the overall structural strength of the clamping assembly, increasing maintenance costs and safety hazards, thereby reducing the equipment's practicality. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a quick assembly device for galvanized sheet ducts. This device addresses the issue that the clamping blocks are fastened to the clamping arms with multiple bolts. During long-term use, the bolts are easily corroded by dust and moisture, resulting in rust. This leads to a significant amount of time spent on rust removal and loosening during disassembly. Some severely rusted bolts even show stripped threads, making disassembly difficult. This not only prolongs downtime for maintenance but may also damage the clamping arms or other components due to forced disassembly. Welded clamping blocks also present a challenge in replacement. Once a clamping block wears out and needs to be replaced, the welded parts must be removed through cutting, grinding, and other processes. This is not only complex and inefficient but may also damage the overall structural strength of the clamping components, increasing maintenance costs and safety hazards, thereby reducing the practicality of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick assembly device for galvanized sheet ducts, comprising a support base and two sliding seats, each of which is provided with two limiting components;

[0006] The limiting component includes a movable seat and a clamping block. The upper surface of the movable seat has two first T-shaped block slots. The lower surface of the clamping block is fixedly connected to two first T-blocks. The upper surface of the movable seat has a limiting block slot. The outer wall of the lower end protrusion of the clamping block is rotatably connected to a rotating threaded rod sleeve. The end of the lower end protrusion of the clamping block near the movable seat has a slot in which the limiting block is slidably connected.

[0007] The clamping block has two sliding rods slidably connected to the outer wall of the protrusion at one end, and a rotating threaded rod is provided inside the groove of the protrusion at one end. The four limiting components are in groups of two, and the two groups of limiting components work together.

[0008] Preferably, the outer walls of the two first T-blocks are slidably connected to the interior of the corresponding first T-block groove, and the clamping surface at the upper end of the clamping block is V-shaped.

[0009] The end of the limiting block near the limiting block groove slides to the outside of the protrusion at one end of the clamping block and slides to the inside of the limiting block groove.

[0010] Preferably, the ends of the two slide rods near the limiting block are slidably extended into the protrusion on the clamping block and are fixedly connected to the outer wall of the limiting block, and the end of the rotating threaded rod near the limiting block is fixedly connected to the upper surface of the limiting block.

[0011] The end of the rotating threaded rod sleeve near the limiting block extends into the protrusion on the clamping block, while the end of the rotating threaded rod away from the limiting block is connected to the internal thread of the rotating threaded rod sleeve.

[0012] Preferably, the upper surface of the support base has two second T-shaped block grooves, and the outer walls of the T-shaped blocks on both sides of the lower end of the two sliding seats are respectively slidably connected to the interior of the corresponding second T-shaped block grooves;

[0013] The support base has a groove on its upper surface that is rotatably connected to a first bidirectional threaded rod, and the protrusions at the lower ends of the two sliding seats are threaded to the outer wall of the first bidirectional threaded rod.

[0014] Preferably, a first motor is fixedly installed inside the groove at one end of the support base, and the output end of the first motor extends rotatably into the groove on the upper surface of the support base and is fixedly connected to one end of the first bidirectional threaded rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This galvanized sheet metal duct quick assembly device uses a rotating threaded sleeve in the limiting assembly. The rotating threaded sleeve and the rotating threaded rod are threaded together, causing the rotating threaded rod to drive the limiting block to slide into the clamping block. The limiting block then exits from the limiting block slot of the moving seat, releasing the clamping block from its fixation. At this point, the clamping block can be slid out of the first T-shaped block slot of the moving seat. This makes disassembling the clamping block simple and quick, effectively improving the maintenance and repair efficiency of the clamping block, while reducing the workload of the workers.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a quick assembly device for galvanized sheet air ducts, including a support base 1 and two sliding seats 3;

[0031] Two limit components are provided on each of the two sliding seats 3;

[0032] The limiting assembly includes a movable base 5 and a clamping block 6. The upper surface of the movable base 5 has two first T-shaped block grooves 9. The lower surface of the clamping block 6 is fixedly connected to two first T-shaped blocks 17. The outer walls of the two first T-shaped blocks 17 are slidably connected to the interior of their respective first T-shaped block grooves 9. The upper clamping surface of the clamping block 6 is V-shaped. The upper surface of the movable base 5 has a limiting block groove 13. A rotating threaded rod sleeve 8 is rotatably connected to the outer wall of the lower protrusion of the clamping block 6. A groove is formed at the lower end of the lower protrusion of the clamping block 6 near the movable base 5, and a limiting block 14 is slidably connected inside. The end of the limiting block 14 near the limiting block groove 13 extends slidably to the outside of the protrusion at one end of the clamping block 6 and is connected to the limiting block groove 13. The clamping block 6 has an internal sliding connection. Two sliding rods 7 are slidably connected to the outer wall of the protrusion at one end of the clamping block 6. The ends of the two sliding rods 7 near the limiting block 14 extend into the protrusion on the clamping block 6 and are fixedly connected to the outer wall of the limiting block 14. A rotating threaded rod 12 is provided inside the protrusion groove at one end of the clamping block 6. The end of the rotating threaded rod 12 near the limiting block 14 is fixedly connected to the upper surface of the limiting block 14. The end of the rotating threaded rod sleeve 8 near the limiting block 14 extends rotatably into the protrusion on the clamping block 6. The end of the rotating threaded rod 12 away from the limiting block 14 is threadedly connected to the inside of the rotating threaded rod sleeve 8. The four limiting components are used in pairs, and the two sets of limiting components work together.

[0033] The support base 1 has two second T-shaped block grooves 15 on its upper surface. The outer walls of the T-shaped blocks on both sides of the lower end of the two sliding seats 3 are slidably connected to the interior of the corresponding second T-shaped block grooves 15. A first bidirectional threaded rod 10 is rotatably connected inside the groove on the upper surface of the support base 1. The protrusions at the lower ends of the two sliding seats 3 are threadedly connected to the outer walls of the first bidirectional threaded rod 10. A first motor 2 is fixedly installed inside the groove at one end of the support base 1. The output end of the first motor 2 extends rotatably into the groove on the upper surface of the support base 1 and is fixedly connected to one end of the first bidirectional threaded rod 10. The upper surface of the sliding seat 3 has a groove with a second bidirectional threaded rod 11 rotatably connected inside. The lower end protrusions of the two sets of moving seats 5 are respectively threaded to the outer wall of the corresponding second bidirectional threaded rod 11. The upper surface of the two sliding seats 3 has a third T-shaped block groove 16 on both sides. The lower end T-shaped blocks on both sides of the two sets of moving seats 5 are respectively slidably connected to the interior of the corresponding third T-shaped block groove 16. The outer wall of the fixing plate on one side of the two sliding seats 3 is fixedly installed with a second motor 4. The output ends of the two second motors 4 are rotatably extended into the groove on the upper surface of the sliding seat 3 and are respectively fixedly connected to one end of the corresponding second bidirectional threaded rod 11.

[0034] Furthermore, when using this device, firstly, according to the length of the duct, the first motor 2 is started. The first motor 2 drives the first bidirectional threaded rod 10 to rotate. Since the threads at both ends of the first bidirectional threaded rod 10 are opposite in direction, the two sliding seats 3 will move towards or away from each other on the second T-shaped block groove 15 track of the support base 1 under the threaded transmission until the distance between the two sliding seats 3 is adapted to the length of the duct to be assembled, completing the initial position adjustment. Then, the two sections of galvanized sheet duct to be assembled are placed between the limiting components on the two sliding seats 3 respectively. The second motor 4 is started. The second motor 4 drives the second bidirectional threaded rod 11 to rotate. Since the threads at both ends of the second bidirectional threaded rod 11 are opposite in direction, the two sets of moving seats 5 will move towards each other on the track of the third T-shaped block groove 16 along the second bidirectional threaded rod 11, driving the moving seats 5 to rotate towards each other. Clamping block 6 moves closer to the duct. As clamping block 6 moves closer, its "V" shaped clamping surface gradually fits against the outer wall of the duct until the duct is firmly clamped. After the duct is stably clamped by clamping block 6, the first motor 2 is started again. The first motor 2 drives the first bidirectional threaded rod 10 to rotate, causing the two sliding seats 3 to move towards each other, driving the two clamped duct sections to gradually move closer until the ends of the two duct sections are precisely aligned, completing the assembly operation. Then, when it is necessary to disassemble clamping block 6, rotate the rotating threaded rod sleeve 8. The rotating threaded rod sleeve 8 is threadedly engaged with the rotating threaded rod 12, causing the rotating threaded rod 12 to drive the limiting block 14 to slide into the clamping block 6. The limiting block 14 exits from the limiting block groove 13 of the moving seat 5, releasing the fixation of clamping block 6. At this time, clamping block 6 can be slid out in the first T-shaped block groove 9 of the moving seat 5.

[0035] By rotating the threaded sleeve 8 in the limiting assembly, the threaded sleeve 8 engages with the threaded rod 12, causing the threaded rod 12 to drive the limiting block 14 to slide into the clamping block 6. The limiting block 14 then exits from the limiting block groove 13 of the moving seat 5, releasing the clamping block 6 from its fixation. At this point, the clamping block 6 can be slid out of the first T-shaped block groove 9 of the moving seat 5. This method of disassembling the clamping block 6 is simple and quick, effectively improving the maintenance and repair efficiency of the clamping block 6 while reducing the workload of the staff.

[0044] The first bidirectional threaded rod 10 is rotatably connected in the groove on the upper surface of the support base 1. The threads at both ends are in opposite directions and are threadedly connected to the lower end protrusions of the two sliding seats 3. It rotates under the drive of the first motor 2, causing the two sliding seats 3 to move towards or away from each other to adjust the spacing.
