Description

Technical Field

[0001] This utility model relates to the field of duct installation technology, specifically a duct fixing and locking component. Background Technology

[0002] Air ducts are piping systems used for air transport and distribution. There are two types: composite air ducts and inorganic air ducts. They can be classified according to cross-sectional shape and material. Stainless steel air duct fabrication involves applying sealant to seams, rivet seams, and the four corners of flanges. Before applying sealant, surface dust and oil should be removed. According to cross-sectional shape, air ducts can be divided into round air ducts, rectangular air ducts, and flat oval air ducts, among others. Air duct fixing and locking components are required during installation.

[0003] Existing duct fixing and locking assemblies typically use two sets of semi-circular clamps to hold the duct, and then fix the two sets of clamps with bolts. During the fixing process, there may be an error between the outer diameter of the duct and the diameter of the clamps, which requires the entire duct fixing and locking assembly to be replaced. Utility Model Content

[0028] 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.

[0029] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0030] Example 1

[0031] Please see Figure 1-4This embodiment provides a technical solution: a duct fixing and locking assembly, including a connecting frame 1, a base 2, and a fixing part 3. The connecting frame 1 is made of stainless steel to prevent rusting during long-term use. The base 2 is fixed above the connecting frame 1 and is installed above the connecting frame 1 by multiple sets of bolts to improve the stability of the overall structure. The fixing part 3 is located inside the connecting frame 1 and has a bidirectional threaded rod 301 rotatably connected inside the connecting frame 1. The bidirectional threaded rod 301 is made of stainless steel to prevent rusting during long-term use. A threaded plate 302 is sleeved on the bidirectional threaded rod 301, and the threaded plate 302 has a threaded groove that mates with the bidirectional threaded rod 301. The threaded groove of the threaded plate 302 is threadedly connected to the bidirectional threaded rod 301. The rotation of the bidirectional threaded rod 301 will cause the threaded plate 302 to move horizontally under the influence of the threads. A fixing block 303 is fixed on one side of the threaded plate 302 inside the connecting frame 1. The threaded plate 302 is fixed by bolts. Connected to the fixed block 303, the movement of the threaded plate 302 will drive the fixed block 303 to move. The movement of the fixed block 303 can clamp pipes of different sizes. There are two sets of fixed blocks 303, and rubber pads are provided on the inner side of both sets of fixed blocks 303. The two sets of fixed blocks 303 with rubber pads can better fix the pipe and prevent the pipe from shaking. A bearing seat 304 is fixed on the inner wall of the connecting frame 1, and the bearing seat 304 is rotatably connected to the bidirectional threaded rod 301. 4 can limit the bidirectional threaded rod 301 to ensure the stability of the bidirectional threaded rod 301 during rotation. A guide rod 305 is provided on the inner side of the connecting frame 1, and the guide rod 305 is slidably connected to the threaded plate 302. The guide rod 305 can limit the threaded plate 302 to ensure the stability of the threaded plate 302 during movement. A support plate 4 is fixed at the bottom of the connecting frame 1, and the support plate 4 is made of stainless steel. The support plate 4 can be used to temporarily fix the unfixed pipe, making it easier for workers to fix the pipe.

[0032] Example 2

[0033] Please see Figure 1-4The limiting part 5 is located above the connecting frame 1. The limiting part 5 includes a pull plate 501, which is made of stainless steel to prevent rusting during prolonged use. A limiting block 502 is fixedly attached to the bottom of the pull plate 501, and the bottom of the pull plate 501 is welded to the limiting block 502 to prevent separation. The limiting block 502 is slidably connected to the connecting frame 1. A spring 503 is also fixedly attached to the bottom of the pull plate 501, and the bottom end of the spring 503 is connected to the outer wall of the connecting frame 1. The spring 503 is in a stretched state, and the elastic force of the spring 503 causes the limiting block 501 to move. 02 is tightly fitted to the bidirectional threaded rod 301 to prevent the bidirectional threaded rod 301 from rotating due to external influences. A rotating rod 505 is rotatably connected to the upper part of the outer wall of the connecting frame 1. A rotating plate 506 is fixed above the rotating rod 505. The rotating rod 505 and the rotating plate 506 can cooperate to temporarily fix the pulling plate 501, so as to prevent the limiting block 502 from affecting the bidirectional threaded rod 301 when rotating. A sliding rod 504 is fixed to the upper part of the outer wall of the connecting frame 1, and the sliding rod 504 is slidably connected to the pulling plate 501. The sliding rod 504 passes through the hole formed in the center of the spring 503. The sliding rod 504 can limit the spring 503 and reduce the deformation and misalignment of the spring 503.

[0034] Working principle: First, when it is necessary to fix the pipe, place the pipe between the two sets of fixing blocks 303, pull the pulling plate 501 upward, the upward movement of the pulling plate 501 will drive the limiting block 502 to move upward, the upward movement of the limiting block 502 will separate from the bidirectional threaded rod 301, and the limiting block 502 will pull the spring 503 to deform. When the pulling plate 501 moves to the position above the rotating plate 506, rotate the rotating plate 506. The rotating plate 506 rotates to the position below the pulling plate 501. Release the pulling plate 501, the spring 503 returns to its deformation and pulls the pulling plate 501 downward to fit against the rotating plate 506;

[0035] Secondly, rotating the bidirectional threaded rod 301, which is threadedly connected to the threaded plate 302 and slidably connected to the connecting frame 1, causes the threaded rod 301 to rotate horizontally. This horizontal movement of the threaded plate 302 causes the fixing block 303 to move, and the fixing block 303 moves to fit against both sides of the pipe. The pipe is fixed by the two sets of fixing blocks 303. After the fixing block 303 fits against the pipe, rotating the rotating plate 506 in the opposite direction causes it to rotate and separate from the pulling plate 501. The spring 503 returns to its original deformation and pulls the pulling plate 501. The downward movement of the pulling plate 501 causes the limiting block 502 to move downward. The limiting block 502 moves downward and fits against the bidirectional threaded rod 301, thus limiting and fixing the bidirectional threaded rod 301 and preventing it from rotating due to external influences.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
