Description

Technical Field

[0001] This utility model relates to the field of pipe fixing technology, and in particular to a circular air guide pipe fixing device. Background Technology

[0002] Chinese Patent Document No.: CN207093941U, Patent Title: A Pipe Clamp, comprising an arc-shaped plate for restricting a round pipe within its inner circumference, wherein the arc-shaped plate is fixedly connected to a hook-shaped connecting structure, the hook-shaped connecting structure including a hook away from the end of the hook-shaped connecting structure connected to the arc-shaped plate, and a fixing hook that engages with the hook at the end of the arc-shaped plate near the hook. After the round pipe is fitted into the arc-shaped plate, the hook-shaped connecting structure is rotated with its connection end with the arc-shaped plate as the axis of rotation in the direction of the round pipe, so that the hook and the fixing hook engage together. The hook-shaped connecting structure applies a compressive force to the arc-shaped plate, causing the opening of the arc-shaped plate to close, thereby applying pressure to the round pipe passing through the arc-shaped plate and fixing the round pipe within the arc-shaped plate. This process is shorter than bolt connection, saving pipe fitters time in assembling pipe clamps.

[0003] Although the above patent can save workers time in fixing the circular air tube, as a snap-fit ​​fixing method, the circular air tube is prone to disengagement when it needs to be fixed for a long time. Once disengaged, the circular air tube will fail to be fixed. Therefore, the above patent is not suitable for fixing the circular air tube for a long time. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a circular air tube fixing device that can quickly and securely fix the circular air tube for extended periods. The inclusion of hand-tightening bolts and a limiting plate helps to restrain the locking claws, preventing deformation and disengagement during prolonged use.

[0005] To achieve the above objectives, this utility model provides a circular air guide tube fixing device, comprising an upper cover and a lower cover. The left side of the upper cover is rotatably connected to the left side of the lower cover; the right side of the upper cover is fixedly connected to an upper cover plate; the right side of the lower cover is fixedly connected to a lower cover plate; the upper cover plate is fixedly connected to a claw; the lower cover plate is provided with a claw hole that mates with the claw; the lower cover plate is provided with a limiting plate for abutting the claw; the limiting plate is slidably connected to the lower cover plate; the limiting plate is rotatably connected to a hand-tightening bolt; the hand-tightening bolt is threadedly connected to the lower cover plate; and a fixing rod is fixedly connected to the bottom of the lower cover.

[0006] According to the circular air duct fixing device of this utility model, the lower cover plate is fixedly connected to one end of the first tension spring, and the other end of the first tension spring is fixedly connected to the limiting plate; the lower cover plate is provided with a clearance space for the limiting plate to retract.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely for explaining the present utility model and are not intended to limit the present utility model.

[0023] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 9This utility model provides a circular air guide tube fixing device, which includes an upper cover 1 and a lower cover 2. When the upper cover 1 and lower cover 2 are fastened together, a cylindrical fixing space is formed in the middle. This cylindrical fixing space can better fit the outer wall of the circular air guide tube, making the fixing of the circular air guide tube more secure. The left side of the upper cover 1 is rotatably connected to the left side of the lower cover 2. Rotating the upper cover 1 to disengage from the lower cover 2 facilitates the placement and removal of the circular air guide tube. The right side of the upper cover 1 is fixedly connected to an upper cover plate 4, and the right side of the lower cover 2 is fixedly connected to a lower cover plate 7. The upper cover plate 4 is fixedly connected to a claw 5, and the lower cover plate 7 has a claw hole 11 that mates with the claw 5. After the claw 5 passes through the claw hole 11, it engages with the bottom of the lower cover plate 7, completing the fixing of the circular air guide tube. The lower cover plate 7 is equipped with a limiting plate 16 for abutting the claw 5. The limiting plate 16 is slidably connected to the lower cover plate 7, and the limiting plate 16 is rotatably connected to a hand-tightening bolt 8. The hand-tightening bolt 8 is threadedly connected to the lower cover plate 7. After the circular air guide tube completes the fastening and fixing of the claw 5, the hand-tightening bolt 8 is turned so that the limiting plate 16 abuts against the claw 5, which can prevent the claw 5 from deforming and disengaging during long-term use. The bottom of the lower cover 2 is fixedly connected to a fixing rod 3. The setting of the fixing rod 3 can facilitate the fixing of the lower cover 2. The fixing rod 3 can be installed in the designated position to fix the lower cover 2.

[0024] See Figure 4 , Figure 6 , Figure 7 , Figure 9 Furthermore, the lower cover plate 7 of this utility model is fixedly connected to one end of the first tension spring 18, and the other end of the first tension spring 18 is fixedly connected to the limiting plate 16. The lower cover plate 7 is provided with a clearance space for the retraction of the limiting plate 16. The clearance space allows the limiting plate 16 to retract completely into the lower cover plate 7. The first tension spring 18 allows the limiting plate 16 to actively retract into the clearance space when there is no threaded connection between the hand-tightening bolt 8 and the lower cover plate 7, thereby reducing the number of turns required to tighten the hand-tightening bolt 8 and improving efficiency. An L-shaped frame 12 is fixedly connected below the limiting plate 16. The L-shaped frame 12 is slidably connected to the release pin 13. The upper end of the second tension spring 14 is fixedly connected below the L-shaped frame 12. The lower end of the second tension spring 14 is fixedly connected to the lower end of the release pin 13. The release pin 13 can abut against the claw 5 when the threaded connection of the hand-tightening bolt 8 is released, pushing the claw 5 to deform and release the claw 5 from the lower cover plate 7, simplifying the steps of disassembling the circular air guide tube.

[0025] See Figure 2 , Figure 5 , Figure 7 , Figure 8Furthermore, the claw 5 of this utility model is provided with a slot 15 that cooperates with the release pin 13. The slot 15 avoids the lower part of the L-shaped frame 12 being too long, and at the same time, the slot 15 facilitates cooperation with the release pin 13. A placement hole is provided on the left side of the lower cover 2, and a compression spring 17 is installed inside the placement hole. The bottom end of the compression spring 17 is fixedly connected to the lower cover 2, and the top end of the compression spring 17 is fixedly connected to the ejector post 6. The placement hole can accommodate the ejector post 6 and prevent the ejector post 6 from affecting the fastening of the upper cover 1 and the lower cover 2. The compression spring 17 and the ejector post 6 can push open the upper cover 1 when the claw 5 is released, which facilitates the automatic separation of the upper cover 1 and the lower cover 2. The lower cover plate 7 is slidably connected to the extension rod 9. Both ends of the extension rod 9 are provided with a stop block 10. The extension rod 9 can provide support for the end of the air guide tube when it is fixed, preventing the air guide tube from sliding under the action of gravity.

[0026] Operating principle: For temporary fixation, the upper cover 1 and lower cover 2 are fastened together, allowing the claw 5 to engage with the lower cover 7. For long-term fixation, after fastening the upper cover 1 and lower cover 2, the hand-tightening bolt 8 is turned, causing the limiting plate 16 to abut against the claw 5. During the movement of the limiting plate 16, the release pin 13 is pressed downward by the claw 5. After passing the claw 5, the release pin 13 springs back and moves upward into the slot 15. To release the long-term fixation, the hand-tightening bolt 8 is turned, and the release pin 13 moves with the limiting plate 16, pushing the claw 5 to deform and disengage from the bottom of the lower cover 7. After the claw 5 is released, the ejector pin 6 pushes open the upper cover 1.

[0027] In summary, this utility model provides a circular air guide tube fixing device, including an upper cover and a lower cover. When the upper and lower covers are fastened together, they form a cylindrical space for the circular air guide tube, which facilitates a more secure and snug fit. The left side of the upper cover is rotatably connected to the left side of the lower cover, preventing separation of the upper and lower covers and facilitating the placement of the circular air guide tube. An upper cover plate is fixedly connected to the right side of the upper cover, and a lower cover plate is fixedly connected to the right side of the lower cover. The design of the upper and lower cover plates allows for the convenient installation of claws and claw holes. Claws are fixedly connected to the upper cover plate, and claw holes that mate with the claws are provided on the lower cover plate, facilitating easy fastening. The design of the claw holes serves as a channel for the claws to pass through, facilitating their engagement with the bottom of the lower cover plate. The lower cover plate features a limiting plate that abuts against the claws, ensuring that the claws' side walls abut against both the limiting plate and the lower cover plate, preventing deformation and disengagement after prolonged stress. The limiting plate is slidably connected to the lower cover plate and rotatably connected to a hand-tightening bolt. This bolt is threadedly connected to the lower cover plate, allowing it to rotate and engage with the limiting plate, thus pushing it against the claws. Simultaneously, the bolt also limits the limiting plate's movement, preventing it from sliding. A fixing rod is fixedly connected to the bottom of the lower cover, facilitating its secure connection to other components.

[0028] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
