Description

Technical Field

[0001] This utility model relates to the field of hanger technology, and more specifically, to a hanger for heating and ventilation ducts. Background Technology

[0002] Existing duct hangers mostly use fixed-size designs, which can only be used for ducts of specific specifications and cannot be compatible with duct systems of different diameters and cross-sectional shapes. When there are multiple specifications of ducts in a project, multiple sets of hangers of different specifications are required, increasing material costs and inventory management complexity. Traditional hangers have a narrow height adjustment range, usually only a few centimeters, which is difficult to meet the needs of large-scale changes in duct elevation in complex building structures, especially in areas with high ceilings or dense ductwork, where the adjustment capability is severely insufficient.

[0003] Traditional duct height adjustment typically requires specialized tools such as wrenches and screwdrivers, involves numerous steps, and necessitates repeated adjustments. Most existing ducts use traditional methods such as bolt tightening and welding for fixation, which takes a considerable amount of time. Once fixed, any further adjustment requires complete disassembly and reassembly, lacking the ability for rapid adjustment and temporary fixation. The installation and adjustment of traditional ducts usually require multiple people to work together, with one person supporting the duct while others adjust and fix it. In confined spaces or at heights, this makes coordination difficult and poses safety hazards. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a hanger for heating and ventilation ducts to solve the technical problems mentioned in the background art, such as the difficulty in adapting to different specifications of pipes and the inconvenience of fixing and disassembling before and after adjustment.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hanger for heating and ventilation ducts, comprising a square frame, a duct pressing mechanism, a position locking mechanism, and a fixing auxiliary mechanism. The duct pressing mechanism includes a fixed pipe and an adjusting pipe. The fixed pipe is fixedly installed at the top and bottom ends of the square frame. The adjusting pipe is slidably installed inside the fixed pipe. A guide roller frame is installed at one end of the adjusting pipe, and adjusting frames are installed on both sides of the adjusting pipe. The adjusting frames are longitudinally slidably arranged on the side wall of the fixed pipe. An adjusting spring is installed between the adjusting frame and the top inner wall of the fixed pipe. A mating plate is installed at the bottom end of the adjusting frame. The position locking mechanism includes a support pipe and a locking rod. The support pipe is fixedly installed on the mating plate. A locking tube is rotatably installed on the support pipe. The locking rod can be directionally extended into the support pipe. An inner sleeve is installed on the inner wall of the locking tube. A sleeved block is installed on the outer wall of the locking rod. The inner sleeve is fitted onto the sleeved block. A bidirectional spring rod is installed on the sleeved block. A stabilizing hole is opened inside the sleeved block, and the bidirectional spring rod can extend into the stabilizing hole.

[0008] The present invention is further configured such that the fixing auxiliary mechanism includes a driving ring and an outer fixing ring. The driving ring is installed at the bottom end of the outer wall of the clamping tube, and the outer fixing ring is fixedly installed on the outer wall of the support tube. A rotating plate is installed at the bottom end of the driving ring, and multiple sets of rotating plates are provided. A positioning spring is installed on the outer fixing ring, and multiple sets of positioning springs are provided. A positioning groove is opened on the rotating plate, and different positioning springs extend into the positioning groove on the rotating plate in stages, so that the driving ring stably drives the clamping tube to rotate.

[0009] The present invention is further configured such that the square frame is provided in two sets, and a connecting frame is provided between the two sets of square frames. The two sets of square frames are connected by the connecting frame to form a stable load-bearing frame, providing a reliable structural foundation and adapting to the installation requirements of different spans.

[0010] The present invention is further configured such that an mounting plate is installed on the connecting frame, and the device is fixed in the required position by fixing the mounting plate. The mounting plate is installed on the connecting frame to realize a firm connection between the entire device and the building structure, and to ensure the overall stability of the hanging system.

[0011] The present invention is further configured such that a longitudinal groove is provided on the side wall of the fixed tube, and the adjusting bracket is longitudinally slidably arranged on the longitudinal groove.

[0012] The present invention is further configured such that a guide rod and a longitudinal plate are fixedly installed on the outer wall of the fixed tube, the adjustment frame is slidably guided on the guide rod, the longitudinal groove controls the sliding trajectory of the adjustment frame, the guide rod provides precise guidance, and the dual guidance mechanism ensures motion accuracy and stability.

[0013] The present invention is further configured such that the longitudinal plate is provided with adjustment holes, and multiple sets of adjustment holes are provided.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a hanger for heating and ventilation ducts, which has the following advantages:

[0017] This invention features a pipe-body pressure-adjusting mechanism. By adjusting the sliding fit of the pipe within the fixed pipe, combined with the dual guiding mechanism of the adjusting frame on the longitudinal groove and guide rod, precise stepless adjustment of the duct support height is achieved. The continuous pre-pressure provided by the adjusting spring ensures that the duct receives stable and uniform support.

[0018] This utility model is equipped with a position locking mechanism. The locking rod achieves multi-position selective locking through multiple sets of adjustment holes on the longitudinal plate. The sleeve structure of the inner sleeve and the sleeved block, together with the bidirectional spring rod stabilizing hole, forms a reliable bidirectional locking mechanism. This not only achieves fast mechanical locking and convenient operation, but also prevents accidental disengagement and excessive insertion through limit rotation and buffer protection functions, ensuring stability and safety for long-term use.

[0019] This utility model is equipped with a fixed auxiliary mechanism. The step-by-step cooperation of multiple sets of positioning springs and the positioning groove of the rotating plate realizes precise graded angle positioning control. The rotating ring stabilizes the rotation of the locking tube and provides smooth and shock-free transmission control. The entire locking process can be completed through a simple rotation operation. It is not only intuitive and convenient to operate, but also has the function of preventing misoperation. The stable support of the outer fixing ring significantly improves the overall durability of the mechanism. Attached Figure Description
