Description

Technical Field

[0001] This utility model relates to the field of hangers, and in particular to a constant force support hanger with adjustable height. Background Technology

[0002] A search of Chinese patents revealed publication number CN209275971U, which discloses a spring-type constant force support, relating to the field of spring supports. The spring-type constant force support includes a housing, a spring base plate fixed to the housing, a displacement frame assembly, and a deflection mechanism. The displacement frame assembly includes a tube, a spring, multiple ball bearings, and a connecting plate that engages with the ball bearings. The tube slides through the spring base plate, with one end of the tube coaxially rotatably connected to the deflection mechanism and the other end connected to a mounting part. The spring is sleeved on the outer wall of the tube, with a first gap between the spring and the outer wall of the tube. One end of the spring is connected to the mounting part, and the other end is connected to the spring base plate via the connecting plate. The connecting plate is circumferentially disposed on the outer wall of the tube, with ball bearings rollingly embedded on the side of the connecting plate near the tube. Multiple ball bearings are spaced circumferentially along the connecting plate, each ball bearing protruding from the connecting plate and abutting against the outer wall of the tube, engaging with the tube in a rolling manner. This design reduces frictional resistance and effectively improves the constant force performance of the spring-type constant force support.

[0003] In summary, the current constant force support is not height-adjustable and has a fixed length. During use, it needs to be adjusted according to the actual situation. If different pipe heights are required, the constant force support needs to be replaced, significantly increasing usage costs, reducing practicality and applicability, and making pipe installation and removal inconvenient. The constant force support is fixed to the pipe with bolts, requiring tools for installation and removal, which is cumbersome, increases workload, and reduces work efficiency. To address these problems, we propose a height-adjustable constant force support. Utility Model Content
