Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically to an adjustable pipeline installation bracket. Background Technology

[0002] A fan delivery system typically includes a fan, air supply ducts, and connecting structures for connecting the fan and air supply ducts, such as flanges and clamps.

[0003] When installing a fan delivery system, the ground at the construction site is often uneven due to the difficulty in ensuring absolute flatness. Since the air supply duct is usually straight, the uniform mounting brackets used in traditional technology cannot accommodate the varying heights between the air supply duct and the ground. Forced installation will reduce the straightness of the duct and cause the connection structure to bear unnecessary eccentric loads. Summary of the Invention

[0004] In order to overcome the problem in the above-mentioned background technology that "the uniform mounting bracket cannot adapt to the different height gaps between the air duct and the ground", this utility model provides an adjustable pipe mounting bracket.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is:

Detailed Implementation

[0035] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0036] Reference Figures 1-2 This embodiment provides an adjustable duct mounting bracket, including a first base 1, a second base 2, and a screw assembly 3. The first base 1 is installed on the ground, and the second base 2 is connected to the bottom surface of the air supply duct. The distance between the first base 1 and the second base 2 is adjusted by the screw assembly 3 to accommodate the varying heights of the air supply duct and the ground, so that the air supply duct can be installed in a straight line on uneven ground.

[0037] Reference Figures 1-3 The screw assembly 3 includes an upright rod 31; the rod 31 serves to support and adjust between the first seat 1 and the second seat 2.

[0038] Reference Figure 2 The first base 1 includes a first cylinder 11, a first mounting plate 12, a first sealing plate 13, and a first nut 14. The first mounting plate 12 is fixedly installed at the bottom end of the first cylinder 11 (e.g., by welding). The first sealing plate 13 is fixedly installed at the top end of the first cylinder 11 (e.g., by welding or by an integral connection). The first nut 14 is fixedly connected to the top surface of the first sealing plate 13 (e.g., by welding). The bottom end of the rod 31 is inserted into the first nut 14 and is adjustablely connected to the first nut 14 by a thread. When the rod 31 rotates, it can move relative to the position of the first nut 14 along the axial direction of the first nut 14, thereby moving closer to or further away from the first nut 14.

[0039] Reference Figure 2 The second base 2 includes a second cylinder 21, a second mounting plate 22, a second sealing plate 23, and a second nut 24. The second mounting plate 22 is fixedly installed on the top end of the second cylinder 21 (e.g., by welding). The second sealing plate 23 is fixedly installed on the bottom end of the second cylinder 21 (e.g., by welding or by an integral connection). The second nut 24 is located at the position of the second sealing plate 23 and is fixedly connected to the bottom surface of the second sealing plate 23 (e.g., by welding). The top end of the rod 31 is inserted into the second nut 24 and is adjustablely connected to the second nut 24 by a thread. When the rod 31 rotates, it can move relative to the position of the second nut 24 along the axial direction of the second nut 24, thereby moving closer to or away from the second nut 24.

[0040] The first mounting plate 12 has several first mounting holes on its outer edge. In use, expansion bolts are installed in the first mounting holes and driven into the ground to fix the first mounting plate 12 to the ground. The second mounting plate 22 has several second mounting holes on its outer edge, into which mounting bolts are inserted. These mounting bolts are directly or indirectly fixed to the air supply duct. First screw holes are provided on the side wall or mounting fins of the air supply duct. Mounting bolts are placed in these first screw holes and tightened to achieve a direct connection between the mounting bolts and the air supply duct. A clamp is installed on the outer surface of the air supply duct, and a second screw hole is provided on the clamp. Mounting bolts are placed in these second screw holes and tightened to achieve an indirect connection between the mounting bolts and the air supply duct.

[0041] The first mounting hole has no fewer than three holes, and each mounting hole is fitted with an expansion bolt; the second mounting hole has no fewer than two holes, and each second mounting hole is fitted with a mounting bolt, thereby achieving stable installation of this utility model.

[0042] The first sealing plate 13 is provided with a first through hole, which communicates with the inner cavity of the first nut 14 and the inner cavity of the first cylinder 11; the bottom end of the rod 31 is inserted into the inner cavity of the first cylinder 11. The first through hole and the inner cavity of the first cylinder 11 are used to provide a receiving space for the rod 31.

[0043] The second sealing plate 23 is provided with a second through hole, which communicates with the inner cavity of the second nut 24 and the inner cavity of the second cylinder 21; the top end of the rod 31 is inserted into the inner cavity of the second cylinder 21. The second through hole and the inner cavity of the second cylinder 21 are used to provide a receiving space for the rod 31.

[0044] Reference Figure 2 and Figure 3 The rod 31 is a straight rod structure with a constant diameter; the lower part of the rod 31 is provided with a first external thread 311 and the upper part is provided with a second external thread 312; the first external thread 311 and the second external thread 312 have opposite directions of rotation and equal pitch; thus, the first external thread 311 and the second external thread 312 are arranged in an axially symmetrical manner, so that when the rod 31 rotates, the first nut 14 and the second nut 24 move closer or further away from each other under the push of the threads, further realizing the adjustment of the height of the second seat 2, so that this utility model can adapt to the gap between the ventilation duct and the ground with different heights.

[0045] Reference Figures 3-5A mounting protrusion 32 is fixedly connected to the middle of the rod body 31 (e.g., by an integral fixed connection or by bolts). A rotating rod 33 is hinged to the end of the mounting protrusion 32, and the rotating rod 33 can rotate up and down. The rotating rod 33 includes a straight rod portion 331 and a folded portion 332 provided at the end of the straight rod portion 331. The straight rod portion 331 and the folded portion 332 are coaxially fixedly connected at one end (e.g., by an integral fixed connection or by bolts).

[0046] Reference Figure 3 and Figure 6 The surface of the first cylindrical body 11 is provided with a locking groove 111 for accommodating and locking the straight rod portion 331. The inner surface of the locking groove 111 can fit and conform to a portion of the outer surface of the straight rod portion 331. The straight rod portion 331 is a straight rod structure with a constant diameter; the cross-section of the straight rod portion 331 is circular, and the cross-section of the locking groove 111 is semi-circular or fan-shaped, so that the side wall of the straight rod portion 331 near the first cylindrical body 11 can be placed inside the locking groove 111, and the side wall away from the first cylindrical body 11 can be placed outside the locking groove 111.

[0047] Reference Figure 4 , Figure 6 and Figure 8 The screw assembly 3 also includes an annular limiting plate 34. The limiting plate 34 has a gourd-shaped interconnected sleeve hole 341 and a snap-fit ​​hole 342. The sleeve hole 341 is adapted to the outer wall of the first cylinder 11, and the snap-fit ​​hole 342 is adapted to the outer surface of the straight rod portion 331. When the sleeve hole 341 is fitted onto the outer wall of the first cylinder 11 and the snap-fit ​​hole 342 is fitted onto the side wall of the straight rod portion 331 away from the first cylinder 11, the cross-section of the snap-fit ​​hole 342 and the cross-section of the snap-fit ​​groove 111 can form a circular structure that adapts to and snaps to the outer surface of the straight rod portion 331.

[0048] Reference Figure 4 When the limiting plate 34 is sleeved on the surface of the first cylinder 11, under the clamping force of the limiting plate 34, the rotating rod 33 cannot be rotated outward. Therefore, the rotating rod 33 can only be engaged in the locking groove 111 and the rod body 31 cannot rotate. At this time, the distance between the first seat 1 and the second seat 2 cannot be adjusted, thus achieving the height locking of this utility model; see reference. Figure 5 The user pushes the limiting plate 34 up until its height is higher than the mounting protrusion 32. At this time, the locking of this utility model is released. The user rotates the rotating rod 33 outward so that the straight rod part 331 is completely pulled out of the locking groove 111. Then, rotating the rod body 31 can realize the height adjustment of this utility model.

[0049] Reference Figures 3-6A rotary stepped locking structure is provided between the rod 31 and the first cylinder 11 to lock the second cylinder 21 at the required height by preventing relative rotation between the rod 31 and the first cylinder 11. The rotating rod 33, the locking groove 111 and the limiting plate 34 together constitute the rotary stepped locking structure.

[0050] Reference Figure 3 and Figure 4 The folded portion 332 is U-shaped. The end of the folded portion 332 away from the straight rod portion 331 can apply a supporting force to the lower surface of the limiting plate 34, preventing the limiting plate 34 from sliding downward under the action of gravity, which would cause the connection between the locking hole 342 and the straight rod portion 331 to fail. Thus, after the present invention is installed, it can maintain a locked state for a long time to maintain the stability of the air supply duct height.

[0051] Reference Figure 10 and Figure 4 The U-shaped fold-back portion 332 includes an L-shaped rod 3321. Since the L-shaped rod 3321 has a rounded corner 3322 at the right angle, the limiting plate 34 slides down under gravity to the lower edge of the side wall of the locking hole 342 and presses against the rounded corner 3322 (the lower surface of the limiting plate 34 cannot press against the horizontal plane 3323 of the fold-back portion 332). During the operation of the fan conveying system, vibrations are inevitable, causing the locking hole 342 and the rounded corner 3322 to press increasingly tightly, making it difficult for users to push the limiting plate 34 upwards during later equipment maintenance, thus hindering the release of the locking mechanism 33. Therefore, referring to… Figure 11 In this utility model, the L-shaped rod 3321 and the upright support rod 3324, which are integrally fixedly connected, together form a U-shaped folding part 332. The upper end of the upright support rod 3324 can apply a supporting force to the limiting plate 34, thereby preventing the snap hole 342 from contacting the rounded corner 3322.

[0052] Reference Figure 6 The number of locking slots 111 is not less than eight. The locking slots 111 are arranged in an equally spaced circumferential array along the cylindrical sidewall of the first cylinder 11, so that the second base 2 can be locked at different height positions.

[0053] Reference Figure 6 and Figure 7 The first sealing plate 13 has an adapter groove 131 at its edge, which is an adapter slot 111. The number of adapter grooves 131 is equal to the number of slots 111. The adapter grooves 131 and slots 111 are arranged in a one-to-one correspondence and are coaxially arranged. The cross-section of the adapter groove 131 is semi-circular or fan-shaped, so that the side wall of the straight rod part 331 near the first cylinder 11 can be placed inside the adapter groove 131, and the side wall away from the first cylinder 11 can be placed outside the adapter groove 131.

[0054] Reference Figure 6 , Figure 8 and Figure 9 The inner wall of the socket 341 is provided with a snap-fit ​​protrusion 343 that fits the snap-fit ​​groove 111 and the fitting groove 131. When the snap-fit ​​protrusion 343 snaps into the snap-fit ​​groove 111, it can distribute the shear force and torsional force on the straight rod 331 (the weight of the air supply duct acts on the rod 31, and the rod 31 tends to rotate under the action of the thread), thereby improving the service life of this utility model.

[0055] Installation steps: ① Connect the first mounting plate 12 to the ground and the second mounting plate 22 to the air supply duct; ② Rotate the screw assembly 3 horizontally until the second base 2 is at a suitable height; ③ Rotate the swivel rod 33 downward so that the straight rod part 331 is placed in the snap-fit ​​groove 111; ④ Slide the limiting plate 34, which was originally located above the mounting protrusion 32, downward until the limiting plate 34 is pressed against the top of the support rod 3324.

[0056] This utility model has a simple structure, reliable function, and convenient use. The screw assembly 3 adjusts the distance between the first base 1 and the second base 2, adapting to varying heights between the air duct and the ground, allowing for straight installation of the air duct on uneven surfaces. The screw assembly 3 includes a rod 31 with a longitudinally rotating rotating rod 33 in its center. The surface of the first cylinder 11 has a locking groove 111 for accommodating and engaging the straight rod 331. When the limiting plate 34 is fitted onto the side wall of the first cylinder 11, the cross-section of the locking hole 342 and the cross-section of the locking groove 111 form a circular structure that fits the outer surface of the straight rod 331, thus locking the second base 2 and the air duct at the desired height. For later maintenance, simply pushing the limiting plate 34 above the mounting protrusion 32 easily releases the lock, facilitating further adjustment of the air duct height or disassembly of the utility model.

[0059] In conclusion, for those skilled in the art, any changes, modifications, substitutions, or variations made to this utility model based on its guidance, without departing from its principles and spirit, shall still fall within the protection scope of this utility model.
