Description

Technical Field

[0001] The utility model relates to the technical field of pipeline fixing frames, in particular to a pipeline fixing frame for a fresh air system. Background Technique

[0002] The fresh air system includes a ducted fresh air system and a wall-mounted fresh air system. Among them, the ducted fresh air system consists of a fresh air fan and pipeline fittings. The fresh air fan is generally installed at the indoor roof position. Multiple ventilation pipelines are fixed on the roof through existing fixing parts. The air supply pipeline is sent to the air supply point through the indoor aisle. For the fixation of the fresh air system pipeline, it is usually installed on the roof through a fixing frame. However, most of the ventilation pipelines are fixed by clamps. Although the installation method using clamps can effectively improve the installation efficiency, due to its installation on the roof, when it vibrates, the bolts locked by the clamps will become loose, thus affecting the stability of the installation of the fresh air system pipeline. Therefore, we propose a pipeline fixing frame for a fresh air system. Content of the Utility Model

[0003] The utility model provides a pipeline fixing frame for a fresh air system, which solves the problems raised in the above background technique.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A pipeline fixing frame for a fresh air system includes an arc-shaped ring. The arc-shaped ring includes a connecting part and a clamping and positioning part. And on the outer side of the connecting part, there are provided locking teeth, and on the inner side of the clamping and positioning part, there is a clamping groove corresponding to the locking teeth. On the outer side of one end of the arc-shaped ring close to the connecting part, a limiting spring plate is fixedly connected. The limiting spring plate is located on the outer side of the connecting part, and there is a cavity between the connecting part and the limiting spring plate that can accommodate the clamping and positioning part. The inner side of the limiting spring plate can be in contact with both sides of the clamping and positioning part, and a through groove is formed through the middle of the clamping and positioning part. A bolt is commonly threadedly connected to the connecting part and the limiting spring plate, and a limiting mechanism for locking the bolt is installed on both the connecting part and the limiting spring plate.

[0005] Optionally, a mounting seat is fixedly connected to the top of the arc-shaped ring, and one end of a connecting rod is connected to the bottom end of the outer side of the mounting seat through a pin. One end of the connecting rod is movably connected to a telescopic sleeve rod.

[0006] Optionally, one end of the telescopic sleeve rod is connected to an auxiliary fixing seat through a pin. One end of the connecting rod is fixedly connected to a shock-absorbing spring, and one end of the shock-absorbing spring is fixedly connected to the inside of the auxiliary fixing seat.

[0007] Optionally, the limiting mechanism includes a limiting block and a limiting spring. The limiting blocks are respectively movably connected in the connecting part and the limiting spring plate, and one end of the limiting block is circular, and the other end of the limiting block is fixedly connected to a limiting spring.

[0008] Optionally, the other ends of the limiting springs are respectively fixed to the inside of the connecting part or the limiting spring plate, and a plurality of circular limiting grooves are formed on the outer side of the bolt, and the circular ends of the limiting blocks are inserted into the circular limiting grooves.

[0009] The utility model has the following beneficial effects:

[0010] 1. For the fixing bracket of the fresh air system pipeline, by screwing the bolt with the connecting part and the limiting spring plate, the connecting part and the limiting spring plate can clamp the clamping and positioning part, and then limit the clamping relationship between the cogs and the card slots, so as to make the clamping between them more firm, and thus make the installation of the pipeline more stable.

[0011] 2. For the fixing bracket of the fresh air system pipeline, under the action of the elastic force of the limiting spring, the limiting block can extend into the circular limiting groove and be inserted into the circular limiting groove. Under the limitation of the limiting block, resistance can be given to the rotation of the bolt, so that the bolt will not deflect easily, and it is avoided that the bolt may deflect when shaking, thus making its installation more stable.

Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 4 , a fixing bracket for a fresh air system pipeline, including an arc-shaped ring 1. The arc-shaped ring 1 includes a connecting portion 2 and a clamping and positioning portion 3. And there are teeth on the outside of the connecting portion 2, and corresponding slots are provided on the inside of the clamping and positioning portion 3 for clamping the pipeline. A limiting spring plate 5 is fixedly connected to the outside of the arc-shaped ring 1 near one end of the connecting portion 2. The limiting spring plate 5 is located outside the connecting portion 2, and there is a cavity between the connecting portion 2 and the limiting spring plate 5 that can accommodate the clamping and positioning portion 3. Under the limitation of the limiting spring plate 5, the clamping of the clamping and positioning portion 3 will not easily shift, resulting in the separation between the connecting portion 2 and the clamping and positioning portion 3. The inside of the limiting spring plate 5 can contact both sides of the clamping and positioning portion 3, which can limit the clamping and positioning portion 3 and make its connection more stable. And a through groove 4 is provided through the middle of the clamping and positioning portion 3. A bolt 8 is commonly threadedly connected to the connecting portion 2 and the limiting spring plate 5, so that the bolt 8 can pass through the through groove 4 and be connected to the connecting portion 2 smoothly, and then the connecting portion 2 and the limiting spring plate 5 can clamp the clamping and positioning portion 3 smoothly, thus ensuring the stability of the clamping of the clamping and positioning portion 3. And a limiting mechanism for locking the bolt 8 is installed on both the connecting portion 2 and the limiting spring plate 5 to prevent the bolt 8 from deflecting when it shakes, so that its installation is more stable.

[0020] Please refer to Figures 1 to 5 , a mounting seat 6 is fixedly connected to the top of the arc-shaped ring 1. Through the mounting seat 6, it can be installed on the roof. And a connecting rod 12 is connected to the bottom end of the outside of the mounting seat 6 through a pin, forming a hinge structure with the pin as the rotation axis, so that the connecting rod 12 can rotate relative to the mounting seat 6. One end of the connecting rod 12 is movably connected to a telescopic sleeve rod 13, and the connecting rod 12 and the telescopic sleeve rod 13 can move relative to each other.

[0021] Please refer to Figures 1 to 5, one end of the telescopic sleeve rod 13 is connected with an auxiliary fixing seat 7 through a pin, forming a hinge structure with the pin as the rotating shaft, so that the telescopic sleeve rod 13 can rotate relative to the auxiliary fixing seat 7, and then the auxiliary fixing seat 7 can be installed on the roof with adjustable position. One end of the connecting rod 12 is fixedly connected with a shock-absorbing spring 14, and one end of the shock-absorbing spring 14 is fixedly connected with the inside of the auxiliary fixing seat 7. Under the action of the elastic force of the shock-absorbing spring 14, it can buffer the arc-shaped ring 1, so as to achieve the shock-absorbing effect of the pipeline.

[0022] Please refer to Figures 1 to 4 , the limiting mechanism includes a limiting block 10 and a limiting spring 11. The limiting block 10 is respectively movably connected in the connecting part 2 and the limiting spring plate 5. The limiting block 10 can move along a fixed track, and one end of the limiting block 10 is circular, and the other end of the limiting block 10 is fixedly connected with the limiting spring 11.

[0023] Please refer to Figures 1 to 4 , the other end of the limiting spring 11 is respectively fixed to the inside of the connecting part 2 or the limiting spring plate 5. Then, under the action of the elastic force of the limiting spring 11, the limiting block 10 can move smoothly, and then be inserted into the circular limiting groove 9. A plurality of circular limiting grooves 9 are arranged on the outer side of the bolt 8, and the circular limiting grooves 9 are inserted into the circular end of the limiting block 10. Under the action of its circular structure, the limiting block 10 can move smoothly without being locked. Furthermore, when the bolt 8 is locked, the disassembly and installation of the bolt 8 are ensured.

[0024] In summary, when the fresh air system pipeline fixing bracket is used, the pipeline is clamped inside the arc-shaped ring 1, and then the clamping and positioning part 3 is pressed relatively, so that it can move between the connecting part 2 and the limiting spring plate 5. Then, the teeth on the outer side of the connecting part 2 are engaged with the clamping grooves on the inner side of the clamping and positioning part 3, so as to clamp the pipeline. Then, the installation bolt 8 is screwed. Under the screwing of the bolt 8, the connecting part 2 and the limiting spring plate 5 can clamp the clamping and positioning part 3, making the clamping of the pipeline more firm. The bolt 8 passes through the through groove 4. At the same time, when the bolt 8 is screwed, it continuously pushes the limiting block 10 to move. Under the action of the elastic force of the limiting spring 11, when the bolt 8 is finally screwed, the limiting block 10 can be inserted into the circular limiting groove 9, so as to limit the bolt 8 and prevent the bolt 8 from deflecting when shaking. And it is installed on the roof through the mounting seat 6 and the auxiliary fixing seat 7, and under the action of the shock-absorbing spring 14, it can effectively buffer the arc-shaped ring 1, so as to achieve the shock-absorbing effect of the pipeline.
