Description

Technical Field

[0001] This utility model relates to the field of spiral duct installation technology, and specifically discloses an installation structure for a spiral duct. Background Technology

[0002] Spiral ducts, as a core component of ventilation systems, are widely used in various building and industrial settings due to their superior performance and unique design. They are made from high-quality metal sheets using advanced spiral rolling technology, resulting in a continuous spiral seam on the duct wall. This special structure gives the duct excellent strength and stability. Spiral ducts are typically installed in a suspended position near the ceiling.

[0003] In existing technologies, there are two main fixing methods for suspending and installing thin-walled circular spiral ducts: one is to install metal clamps on the outside of the duct, tighten the clamps with bolts to form a rigid constraint, and then bolt the clamp assembly to the ceiling hanger; the other is to use flexible suspension ropes to suspend the duct body. Both methods require the duct load to be transferred to the building roof structure through the hanger system.

[0004] With the rapid development of technology, the method of hoisting spiral ducts using clamp assemblies is extremely cumbersome due to the need for a large number of bolts and the need for tools to tighten and loosen them. Hoisting spiral ducts using flexible ropes is prone to swaying due to the lack of rigid constraints, which affects the stability of the system. Therefore, a new installation structure for spiral ducts is needed to solve this problem. Utility Model Content

[0005] This utility model proposes an installation structure for a spiral duct, which is simple and convenient to operate when assembling and disassembling the spiral duct body, and prevents the spiral duct body from swinging, thereby improving the stability of the system.

[0006] This utility model is implemented as follows: an installation structure for a spiral duct includes a spiral duct body and a rectangular frame. A fixed clamping seat is installed inside the rectangular frame, and a movable clamping seat is provided inside the rectangular frame below the fixed clamping seat. A circular hole is opened through the lower end face of the rectangular frame, and an internally threaded cylinder is provided inside the circular hole. The internal threaded cylinder is threadedly connected to a screw that is fixedly connected to the lower end of the movable clamping seat. A driving mechanism is provided on the lower side of the rectangular frame.

[0007] A connecting cover is provided above the rectangular frame. First limiting plates are fixedly connected to the left and right sides of the inner wall of the connecting cover. A vertical rod extending into the connecting cover is rotatably connected to the upper end of the rectangular frame. Second limiting plates that abut against the upper end of the first limiting plates are fixedly connected to the left and right sides of the outer wall of the vertical rod. A locking mechanism is provided on the outer side of the vertical rod.

[0008] The locking mechanism includes a first disc fixedly connected to the outer wall of the vertical rod. Two limiting holes are formed through the outer wall of the first disc. A second disc is fixedly connected to the outer wall of the connecting cover. Two limiting rods are slidably connected through the outer wall of the second disc. The two limiting rods extend into the two limiting holes and match them. A connecting plate that abuts against the upper end of the first disc is fixedly connected to the outer wall of each of the two limiting rods. A compression spring that sleeves on the outer wall of the two limiting rods and is fixedly connected to the second disc is installed at the upper end of each of the two connecting plates.

[0009] As a preferred installation structure of the spiral duct of this utility model, the driving mechanism includes an L-shaped plate fixedly connected to the lower end face of a rectangular frame, a driving frame fixedly connected to the lower end of the L-shaped plate, a worm gear rotatably connected inside the driving frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft passing through the L-shaped plate fixedly connected between the worm wheel and the internal threaded cylinder, and a handwheel extending to the outside of the driving frame fixedly connected to the right end of the worm gear.

[0010] As a preferred installation structure of the spiral duct of this utility model, the inner wall of the circular hole is provided with an annular groove, and an annular slide rail that is fixedly connected to the outer wall of the internal threaded cylinder is slidably connected inside the annular groove.

[0011] As a preferred installation structure of the spiral duct of this utility model, the inner wall of the rectangular frame is provided with sliding grooves on both the front and rear sides, and the interior of each of the two sliding grooves is slidably connected with a slider that is fixedly connected to the movable clamping seat.

[0012] As a preferred installation structure for a spiral duct of this utility model, the upper ends of both limiting rods are fixedly connected to limiting plates.

[0013] As a preferred installation structure of the spiral duct of this utility model, a fixing rod is fixedly connected to the upper end of the connecting cover, and an installation plate is fixedly connected to the upper end of the fixing rod.

[0014] As a preferred installation structure for a spiral duct of this utility model, both the fixed clamp and the movable clamp have an arc-shaped structure on opposite sides.

[0015] The beneficial effects of this utility model are:

[0016] When installing the spiral duct body, the spiral duct body is brought into contact with the lower side of the fixed clamping seat. The internal threaded cylinder is rotated by the drive mechanism, which in turn moves the movable clamping seat upward and works with the fixed clamping seat to clamp and fix the spiral duct body. Then, the two second limiting plates are adjusted to a front-to-back distribution, allowing the two second limiting plates and the vertical rod to enter the interior of the connecting cover. The vertical rod is then rotated so that the upper ends of the two second limiting plates are in contact with the two first limiting plates. The two limiting rods will then enter the interior of the two limiting holes. Because the two limiting holes and the two limiting rods match, and because the two first limiting plates limit the two second limiting plates, the spiral duct body is hoisted and fixed. This installation method prevents the spiral duct body from swaying and improves the stability of the system.

[0017] When it is necessary to disassemble the spiral duct body, the two limiting rods need to be completely disengaged from the two limiting holes. Then, the two second limiting plates are rotated to positions that intersect with the two first limiting plates, so that the vertical rod can be disengaged from the inside of the connecting cover. Then, by moving the movable clamping seat downward, the spiral duct body can be pulled out from between the movable clamping seat and the fixed clamping seat. Combined with the above installation steps for the spiral duct body, the disassembly and assembly of the spiral duct body is simple and convenient. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-6 An installation structure for a spiral duct includes a spiral duct body 23 and a rectangular frame 1. A fixed clamping seat 2 is installed inside the rectangular frame 1. A movable clamping seat 3 located below the fixed clamping seat 2 is provided inside the rectangular frame 1. A circular hole 4 is opened through the lower end face of the rectangular frame 1. An internal threaded cylinder 5 is provided inside the circular hole 4. A screw 6 fixedly connected to the lower end of the movable clamping seat 3 is threaded inside the internal threaded cylinder 5. A driving mechanism is provided on the lower side of the rectangular frame 1.

[0028] A connecting cover 11 is provided above the rectangular frame 1. A first limiting plate 12 is fixedly connected to the left and right sides of the inner wall of the connecting cover 11. A vertical rod 13 extending into the interior of the connecting cover 11 is rotatably connected to the upper end of the rectangular frame 1. A second limiting plate 14 abutting against the upper end of the first limiting plate 12 is fixedly connected to the left and right sides of the outer wall of the vertical rod 13. A locking mechanism is provided on the outer side of the vertical rod 13.

[0029] The locking mechanism includes a first disc 15 fixedly connected to the outer wall of the vertical rod 13. Two limiting holes 16 are opened through the outer wall of the first disc 15. A second disc 17 is fixedly connected to the outer wall of the connecting cover 11. Two limiting rods 18 are slidably connected through the outer wall of the second disc 17. The two limiting rods 18 extend into the two limiting holes 16 and match them. A connecting plate 19 that abuts against the upper end of the first disc 15 is fixedly connected to the outer wall of each of the two limiting rods 18. A compression spring 20 that is sleeved on the outer wall of the two limiting rods 18 and fixedly connected to the second disc 17 is installed at the upper end of each of the two connecting plates 19.

[0030] In this embodiment: when the spiral duct body 23 is to be clamped and fixed, the spiral duct body 23 needs to pass through the inside of the rectangular frame 1 and fit against the lower side of the fixed clamping seat 2. Then, the internal threaded cylinder 5 is driven to rotate by the drive mechanism. Since the screw 6 is threaded to the inside of the internal threaded cylinder 5, the movable clamping seat 3 is driven to move upward by the screw 6. The movable clamping seat 3 applies pressure to the spiral duct body 23 and can clamp and fix the spiral duct body 23 in conjunction with the fixed clamping seat 2.

[0031] During the hoisting of the spiral duct body 23, the positions of the two second limiting plates 14 can be adjusted when the vertical rod 13 is rotated, so that the two second limiting plates 14 are in a front-to-back distribution state. Since the two first limiting plates 12 are in a left-to-right distribution state, the two second limiting plates 14 and the vertical rod 13 can then enter the interior of the connecting cover 11. At this time, the first disc 15 pushes the two limiting rods 18 upward and stretches the two compression springs 20 until the vertical rod 13 abuts against the top of the interior of the connecting cover 11. Then, the vertical rod 13 and the two second limiting plates 14 are rotated to... The two second limiting plates 14 are attached to the upper ends of the two first limiting plates 12. The two limiting rods 18 will move downward due to the elastic force of the compression spring 20 and enter the interior of the two limiting holes 16 respectively, until the two connecting plates 19 abut against the upper end of the first disc 15. Since the two limiting holes 16 and the two limiting rods 18 are matched, and since the two first limiting plates 12 limit the two second limiting plates 14, the hoisting and fixing of the spiral duct body 23 is completed. Through this installation method, the purpose of preventing the spiral duct body 23 from swinging and improving the stability of the system is achieved.

[0032] When it is necessary to disassemble the spiral duct body 23, the two limiting rods 18 need to be completely disengaged from the inside of the two limiting holes 16. Then, the two second limiting plates 14 are rotated to positions that intersect with the two first limiting plates 12, so that the vertical rod 13 and the two second limiting plates 14 can be disengaged from the inside of the connecting cover 11. Then, the internal threaded cylinder 5 is driven to rotate in the opposite direction by the drive mechanism, so that the movable clamping seat 3 moves downward, thereby allowing the spiral duct body 23 to be pulled out from between the movable clamping seat 3 and the fixed clamping seat 2. Combined with the above installation steps for the spiral duct body 23, the disassembly and assembly of the spiral duct body 23 can be performed in a simple and convenient manner.

[0033] As a technical optimization of this utility model, the driving mechanism includes an L-shaped plate 7 fixedly connected to the lower end face of the rectangular frame 1, a driving frame 8 fixedly connected to the lower end of the L-shaped plate 7, a worm 9 rotatably connected inside the driving frame 8, a worm wheel 10 meshing with the outer wall of the worm 9, a transmission shaft passing through the L-shaped plate 7 fixedly connected between the worm wheel 10 and the internal threaded cylinder 5, and a handwheel extending to the outside of the driving frame 8 fixedly connected to the right end of the worm 9.

[0034] In this embodiment: the worm 9 is rotated by the handwheel, which in turn drives the worm wheel 10 to rotate, and drives the internal threaded cylinder 5 to rotate through the transmission shaft. Since the worm wheel 10 and the worm 9 have a self-locking characteristic, the stability of the drive frame 8 in the non-drive state is improved, and the position of the movable clamping seat 3 is prevented from moving.

[0035] As a technical optimization of this utility model, an annular groove is provided on the inner wall of the circular hole 4, and an annular slide rail is slidably connected inside the annular groove and fixedly connected to the outer wall of the internal threaded cylinder 5.

[0036] In this embodiment, by setting an annular groove and an annular slide rail, the stability of the internal threaded cylinder 5 rotating inside the circular hole 4 is improved.

[0037] As a technical optimization of this utility model, the inner wall of the rectangular frame 1 is provided with sliding grooves on both the front and rear sides, and the sliding grooves are slidably connected to the sliders that are fixedly connected to the movable clamping seat 3.

[0038] In this embodiment, two grooves and two sliders are provided to improve the stability of the moving clamp 3 when moving up and down.

[0039] As a technical optimization of this utility model, the upper ends of the two limiting rods 18 are fixedly connected to limiting disks.

[0040] In this embodiment, a limiting disc is provided to prevent the limiting rod 18 from disengaging from the second disc 17.

[0041] As a technical optimization of this utility model, a fixing rod 21 is fixedly connected to the upper end of the connecting cover 11, and an installation plate 22 is fixedly connected to the upper end of the fixing rod 21.

[0042] In this embodiment: a fixing rod 21 is provided to facilitate the connection of the mounting plate 22, and the mounting plate 22 is provided to facilitate the mounting of the mounting plate 22 to the ceiling by means of fasteners.

[0043] As a technical optimization of this utility model, both the fixed clamping seat 2 and the movable clamping seat 3 have an arc-shaped structure on opposite sides.

[0044] In this embodiment: Since the opposite sides of the fixed clamping seat 2 and the movable clamping seat 3 are both arc-shaped structures, the opposite sides of the fixed clamping seat 2 and the movable clamping seat 3 can fit into the circular surface of the spiral duct body 23, thereby improving the stability of clamping the spiral duct body 23.

[0045] The working principle and usage process of this utility model are as follows: When the spiral duct body 23 needs to be clamped and fixed, the spiral duct body 23 needs to pass through the inside of the rectangular frame 1 and fit against the lower side of the fixed clamping seat 2. Then, the worm 9 is rotated by the handwheel, which in turn drives the worm wheel 10 to rotate, and drives the internal threaded cylinder 5 to rotate through the transmission shaft. Since the screw 6 is threaded to the inside of the internal threaded cylinder 5, the screw 6 drives the movable clamping seat 3 to move upward. The movable clamping seat 3 applies pressure to the spiral duct body 23, and together with the fixed clamping seat 2, the spiral duct body 23 can be clamped and fixed.

[0046] During the hoisting of the spiral duct body 23, the positions of the two second limiting plates 14 can be adjusted when the vertical rod 13 is rotated, so that the two second limiting plates 14 are in a front-to-back distribution state. Since the two first limiting plates 12 are in a left-to-right distribution state, the two second limiting plates 14 and the vertical rod 13 can then enter the interior of the connecting cover 11. At this time, the first disc 15 pushes the two limiting rods 18 upward and stretches the two compression springs 20 until the vertical rod 13 abuts against the top of the interior of the connecting cover 11. Then, the vertical rod 13 and the two second limiting plates 14 are rotated to... The two second limiting plates 14 are attached to the upper ends of the two first limiting plates 12. The two limiting rods 18 will move downward due to the elastic force of the compression spring 20 and enter the interior of the two limiting holes 16 respectively, until the two connecting plates 19 abut against the upper end of the first disc 15. Since the two limiting holes 16 and the two limiting rods 18 are matched, and since the two first limiting plates 12 limit the two second limiting plates 14, the hoisting and fixing of the spiral duct body 23 is completed. Through this installation method, the purpose of preventing the spiral duct body 23 from swinging and improving the stability of the system is achieved.

[0047] When it is necessary to disassemble the spiral duct body 23, the two limiting rods 18 need to be completely disengaged from the inside of the two limiting holes 16. Then, the two second limiting plates 14 are rotated to positions that intersect with the two first limiting plates 12, so that the vertical rod 13 and the two second limiting plates 14 can be disengaged from the inside of the connecting cover 11. Then, the internal threaded cylinder 5 is driven to rotate in the opposite direction by the drive mechanism, so that the movable clamping seat 3 moves downward, thereby allowing the spiral duct body 23 to be pulled out from between the movable clamping seat 3 and the fixed clamping seat 2. Combined with the above installation steps for the spiral duct body 23, the disassembly and assembly of the spiral duct body 23 can be performed in a simple and convenient manner.
