Description

Technical Field

[0001] This utility model relates to the field of mounting bases, specifically to a centrifugal fan mounting base. Background Technology

[0002] Centrifugal fans are a common type of industrial fan, mainly used to transport air and other non-corrosive, non-flammable, non-explosive, and non-sticky gases. Their working principle involves a motor driving an impeller to rotate, causing the gas to rotate and gain kinetic energy. Centrifugal fans require a mounting base for installation. For example, patent CN 203024423 U provides a centrifugal fan mounting base for an air-source heat pump water heater. This base includes two vertically arranged longitudinal beams and an upper and lower crossbeam forming a frame connecting the top and bottom of the longitudinal beams. The top of the upper crossbeam has a protruding arm extending to one side of the upper crossbeam, perpendicular to the upper crossbeam. The other end of the protruding arm opposite the upper crossbeam has a downward-bent edge with a connecting hole. The bottom of the lower crossbeam has a bent foot protruding to the same side as the corresponding protruding arm, perpendicular to the lower crossbeam. Mounting holes for the centrifugal fan are located in the middle of the two longitudinal beams. However, the spacing between these mounting holes is not easily adjustable. Utility Model Content

[0003] The purpose of this utility model is to provide a centrifugal fan mounting base that solves the problem that the spacing of the mounting holes in the mounting base is not easy to adjust.

[0004] To achieve the above objectives, this utility model provides a centrifugal fan mounting base, which includes a base, with slides slidably disposed at both ends of the base. Each slide has a first hole, and the base has a second hole. A pin passes through the first hole and the second hole sequentially to fix the slide to the base. Each slide has a mounting plate with multiple mounting holes. Sliding the slide can move two mounting plates closer together or further apart. The base has a limiting plate with limiting holes. The mounting plate has a fixing plate, and a locking rod is slidably disposed on the fixing plate, with at least a portion of the locking rod extending into the limiting holes to fix the mounting plate to the limiting plate.

[0005] Preferably, the pin is provided with a handle, and a spring is sleeved on the pin. One end of the spring is connected to the slide block, and the other end is connected to the handle.

[0006] Preferably, the lever is rotatably provided with a handle.

[0007] Preferably, the mounting plate is provided with a support plate, and the support plate is provided with a groove. Moving the handle can cause it to engage in the groove so as to move the lever away from the limiting hole.

[0008] Preferably, a return spring is sleeved on the lever, one end of the return spring is connected to the fixing plate, and the other end is connected to the mounting plate.

[0009] This utility model provides a centrifugal fan mounting base, which includes a base, with slides slidably mounted at both ends of the base. Each slide has a first hole, and the base has a second hole. A pin passes through the first hole and the second hole sequentially to fix the slide to the base. A mounting plate with multiple mounting holes is mounted on the slide. Sliding the slide can move two mounting plates closer together or further apart. A limiting plate with limiting holes is provided on the base, and a fixing plate is provided on the mounting plate. A locking rod is slidably provided on the fixed plate, and the locking rod extends at least partially into the limiting hole to fix the mounting plate on the limiting plate. In use, when it is necessary to adjust the distance between the two mounting plates according to the installation requirements of the centrifugal fan, first pull the locking rod out of the limiting hole, then turn the handle so that the handle engages with the groove on the support plate to fix the locking rod on the support plate, then pull the pin away from the second hole, and then slide the slide block so that the slide block drives the mounting plate to move, thereby adjusting the distance. Through a simple structure, the distance between the mounting holes of the centrifugal fan is easy to adjust.

[0010] Beneficial effects: When adjusting the distance between the two mounting plates, first pull the locking rod out of the limiting hole, then turn the handle so that the handle engages with the groove on the support plate, fixing the locking rod on the support plate. Next, pull the pin so that the pin moves away from the second hole. Then, slide the slide block so that the slide block moves the mounting plate to adjust the distance, thus making the mounting hole distance of the centrifugal fan easy to adjust.
