Description

Technical Field

[0001] This utility model relates to the field of coupling technology, specifically a centrifugal pump coupling. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during the transmission of motion and power, and remaining connected under normal conditions. It is a mechanical component used to securely connect the driving and driven shafts in different mechanisms, enabling them to rotate together and transmit motion and torque. Sometimes it also serves as a safety device to prevent the connected components from bearing excessive loads, providing overload protection.

[0003] In existing technologies, the distance between the two shafts in a centrifugal pump coupling is generally fixed, and the overall length cannot be adjusted. In actual use, when the distance between the two shafts to be connected is too large, it is quite troublesome to connect the two shafts, and it is necessary to customize couplings of different lengths for connection. Utility Model Content

[0004] The purpose of this utility model is to provide a centrifugal pump coupling that is simple and convenient to operate, allows for adjustment of the overall length of the coupling, and has strong versatility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal pump coupling, including a mounting base, two slide rails fixedly connected to the left side of the upper end face of the mounting base, a sliding plate slidably connected to the upper end face of the two slide rails, a fixing plate fixedly connected to the right side of the upper end face of the mounting base, two shaft seats fixedly connected to the upper end face of both the sliding plate and the fixing plate, a first connecting shaft rotatably connected through the two shaft seats on the left side, a second connecting shaft rotatably connected through the two shaft seats on the right side, an end block fixedly connected to the opposite end of the first connecting shaft and the second connecting shaft, two movable rods movably connected between the two end blocks via a hinge, a rotating shaft rotatably connected to the left side of the interior of the mounting base, a toothed plate fixedly connected to the lower end face of the sliding plate, and a gear meshing with the toothed plate fixedly connected to the outer wall of the rotating shaft.

[0006] To facilitate connection with an external shaft, in a preferred embodiment of the centrifugal pump coupling of this invention, a connecting sleeve is fixedly connected to the opposite ends of both the first and second connecting shafts.

[0007] In order to drive the shaft to rotate, as a preferred centrifugal pump coupling of this utility model, one end of the shaft extends to the outside of the mounting base and is fixedly connected to a rotating base.

[0008] In order to lock the position of the slide plate, as a preferred centrifugal pump coupling of this utility model, a fixing bolt is threaded through one side of the upper end face of the slide plate.

[0009] In order to install the mounting base, as a preferred centrifugal pump coupling of this utility model, the outer wall of the mounting base is fixedly connected with multiple fixing blocks, and the outer wall of the fixing blocks is provided with fixing holes.

[0010] To facilitate the retraction and movement of the movable rod, the movable rod, as a preferred embodiment of the centrifugal pump coupling of this utility model, is a two-section structure in the shape of a "V", with the two movable rods arranged symmetrically.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The connecting sleeves at opposite ends of the first and second connecting shafts are used to connect with external shafts. The slide plate can slide on the upper end of the slide rail, thereby adjusting the distance between the connecting shafts to be connected as needed. The rotating seat drives the rotating shaft to rotate, which in turn drives the gear to rotate. The gear further drives the toothed plate that meshes with it to move. The toothed plate is fixed at the bottom of the slide plate, so it can drive the slide plate to slide. The slide plate then drives the two shaft seats above it to move, thereby moving the first connecting shaft closer to or away from the second connecting shaft. During the adjustment process, the two movable rods adaptively retract or expand. The operation is simple and convenient, and the overall length of the coupling can be adjusted. It has strong versatility. Attached Figure Description
