Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically a dust collector duct support. Background Technology

[0002] Steel pipe processing is a crucial link in the manufacturing industry, encompassing various processes such as rolling, cutting, and bending. Different processes are suitable for different scenarios, requiring selection based on material properties and application requirements. The following analysis focuses on classification, cutting, bending, and application scenarios. In steel pipe cutting workshops, a large amount of dust and impurities are generated during the cutting process, necessitating dust collectors for dust removal. However, existing dust collector ducts are mostly made of flexible materials and are quite long. During dust removal, the ducts are often manually held with the dust inlet hood facing downwards to facilitate dust entry into the dust collector. However, this manual method wastes significant time and manpower and makes it difficult to adjust the height and tilt angle of the dust inlet hood, causing considerable inconvenience to users. Therefore, we propose a dust collector duct support to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a dust collector duct support to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dust collector duct support, comprising a round steel plate, a first round tube fixedly connected to the top of the round steel plate, a second round tube slidably connected to the inner side of the first round tube, a first semi-circular annular support frame fixedly connected to the top of the second round tube, a circular sleeve slidably fitted on the outer side of the first round tube, two fixing blocks fixedly connected to the outer side of the circular sleeve, a common round rod rotatably connected between the two fixing blocks on their adjacent sides, an inclined tube fixedly fitted on the outer side of the round rod, a second semi-circular annular support frame fixedly connected to the top of the inclined tube, the front end of the round rod extending to the outside of a front fixing block and fixedly connected to a rectangular block, a circular annular block fixedly connected to the front side of the front fixing block, and multiple slots evenly spaced on the front side of the circular annular block.

[0005] In a further preferred embodiment, two of the plurality of slots are movably fitted with a locking rod, and the rectangular block is slidably sleeved on the outside of the locking rod.

[0006] More preferably, the front ends of the two levers are fixedly connected to the same rectangular base, and two springs are fixedly connected between the rectangular block and the rectangular base.

[0007] More preferably, the spring is movably sleeved on the outside of the corresponding lever, and a handle is fixedly connected to the front side of the rectangular base.

[0008] More preferably, a first T-shaped nut is provided above the round steel plate, and the first round pipe thread is sleeved on the outside of the first T-shaped nut.

[0009] More preferably, the end of the first T-shaped nut abuts against the outer side of the second round tube, and the second T-shaped nut is provided above the round steel plate.

[0010] More preferably, the circular sleeve is threaded onto the outside of the second T-nut, and the end of the second T-nut abuts against the outside of the first circular tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By rotating the first T-shaped nut in the reverse direction, the first semi-circular support frame is moved upward to adjust its height. By rotating the second T-shaped nut in the reverse direction, the height of the second semi-circular support frame is adjusted. By holding the handle and moving it forward, the locking rod is separated from the corresponding locking slot. Rotating the handle drives the rectangular seat to rotate, so that the rectangular block drives the inclined tube to rotate through the round rod.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example

[0019] Please see Figure 1-4 This utility model provides a technical solution: a dust collector duct support, including a round steel plate 1, a first round pipe 2 fixedly connected to the top of the round steel plate 1, a second round pipe 3 slidably connected to the inner side of the first round pipe 2, a first semi-circular annular support frame 4 fixedly connected to the top of the second round pipe 3, a round sleeve 5 slidably sleeved on the outer side of the first round pipe 2, two fixing blocks 6 fixedly connected to the outer side of the round sleeve 5, a common round rod 7 rotatably connected between the two fixing blocks 6 on their adjacent sides, an inclined pipe 8 fixedly sleeved on the outer side of the round rod 7, a second semi-circular annular support frame 9 fixedly connected to the top of the inclined pipe 8, the front end of the round rod 7 extending to the outside of a front fixing block 6 and fixedly connected to a rectangular block 10, a circular annular block 11 fixedly connected to the front side of the front fixing block 6, and the front of the circular annular block 11... Multiple slots 12 are evenly spaced on the side. Rotating the first T-nut 17 in the opposite direction moves the first semicircular support frame 4 upward to adjust its height. Rotating the second T-nut 18 in the opposite direction adjusts the height of the second semicircular support frame 9. Holding the handle 16 and moving it forward separates the locking rod 13 from the corresponding slot 12. Rotating the handle 16 drives the rectangular base 14 to rotate, causing the rectangular block 10 to drive the inclined tube 8 to rotate via the round rod 7. The inclined tube 8 drives the second semicircular support frame 9 to rotate to a suitable angle, allowing the duct to be placed inside the first semicircular support frame 4 and the second semicircular support frame 9 for support. This eliminates the need for manual support of the duct, saving a significant amount of time and manpower. It also facilitates the adjustment of the height and tilt angle of the duct's dust inlet hood, providing great convenience to the user.

[0020] In this embodiment, specifically: two of the multiple slots 12 are movably fitted with a locking rod 13, and the rectangular block 10 is slidably sleeved on the outside of the locking rod 13;

[0021] In this embodiment, specifically: the front ends of the two levers 13 are fixedly connected to the same rectangular base 14, and two springs 15 are fixedly connected between the rectangular block 10 and the rectangular base 14;

[0022] In this embodiment, specifically: the spring 15 is movably sleeved on the outside of the corresponding latch 13, and the front side of the rectangular base 14 is fixedly connected to a handle 16;

[0023] In this embodiment, specifically: a first T-shaped nut 17 is provided above the round steel plate 1, and a first round tube 2 is threaded onto the outside of the first T-shaped nut 17;

[0024] In this embodiment, specifically: the end of the first T-shaped nut 17 abuts against the outer side of the second round tube 3, and the second T-shaped nut 18 is provided above the round steel plate 1;

[0025] In this embodiment, specifically: the circular sleeve 5 is threaded onto the outside of the second T-nut 18, and the end of the second T-nut 18 abuts against the outside of the first circular tube 2.

[0026] In operation, this invention works as follows: When adjusting the height of the first semi-circular support frame 4, the first T-nut 17 is rotated in the reverse direction, moving the first semi-circular support frame 4 upwards. The first semi-circular support frame 4 drives the second circular tube 3 upwards. When the first semi-circular support frame 4 reaches the appropriate height, the first T-nut 17 is rotated in the forward direction to fix the first semi-circular support frame 4. When adjusting the height of the second semi-circular support frame 9, the second T-nut 18 is rotated in the reverse direction, moving the circular sleeve 5 downwards. The circular sleeve 5 drives the inclined tube 8 to move, and the inclined tube 8 drives the second semi-circular support frame 9 to move, thus adjusting the height of the second semi-circular support frame 9. When adjusting the tilt angle of the second semi-circular support frame 9, the handle 16 is grasped and moved forward. The handle 16 drives the rectangular base 14 to move. During the movement, the rectangular base 14 stretches the spring 15, causing the two locking rods 13 to move. The locking rods 13 separate from the corresponding locking slots 12. Then, the handle 16 is rotated. Handle 16 drives rectangular base 14 to rotate. Rectangular base 14 drives rectangular block 10 to rotate via two locking rods 13. Rectangular block 10 drives round rod 7 to rotate. Round rod 7 drives inclined tube 8 to rotate. Inclined tube 8 drives second semi-circular support frame 9 to rotate. When the second semi-circular support frame 9 rotates to a suitable angle, the locking rod 13 is aligned with the corresponding slot 12 by observation. The tension on handle 16 is released, and spring 15, which is in a stretched state, returns to its original position. The elastic force of spring 15 drives rectangular base 14 to move. Rectangular base 14 drives two locking rods 13 to move. The locking rod 13 engages with the corresponding slot 12, thereby fixing inclined tube 8 and adjusting the tilt angle of second semi-circular support frame 9. Then, the air duct is placed inside the first semi-circular support frame 4 and the second semi-circular support frame 9 for support, thus forming a dust collector air duct support. It eliminates the need for manual hand-held air duct support, saving a lot of time and manpower. It also facilitates adjustment of the height and tilt angle of the air duct's dust inlet hood, bringing great convenience to the user.
