Description

Technical Field

[0001] This utility model belongs to the technical field of water pump couplings, and more specifically, it relates to a water pump coupling that facilitates diaphragm replacement. Background Technology

[0002] A pump coupling is a mechanical component installed between the pump shaft and the drive shaft (usually the motor shaft) to connect the two shafts and transmit torque and rotational motion. Simply put, it is a "bridge" that efficiently and reliably transmits power from the motor (driving end) to the pump (driven end), enabling them to rotate synchronously.

[0003] Based on existing technology, it has been found that existing water pump couplings are usually fixed by multiple sets of bolts during use. This method of installation is relatively cumbersome, and if the diaphragm is damaged, it cannot be replaced quickly, making the operation inconvenient. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a water pump coupling that facilitates diaphragm replacement. This solves the problem that existing water pump couplings typically use multiple sets of bolts for fixing, which is cumbersome to install and makes it difficult to quickly replace damaged diaphragms, resulting in inconvenient operation.

[0005] This utility model provides a water pump coupling that facilitates diaphragm replacement, achieved through the following specific technical means: A water pump coupling that facilitates diaphragm replacement includes a mounting part, a rotating part, a fixing part, and a connecting part; The mounting part is provided with a rotating part; the fixing part is provided on the side of the mounting part; the connecting part is provided on the side of the fixing part; the connecting part is connected to the mounting part and the connecting part is connected to the rotating part. The mounting part includes: a main body, which is the pump coupling body; a connecting flange is provided on the main body; The fixing part includes: a diaphragm, which is disposed on the side of the connecting flange; a buffer sleeve is disposed on the diaphragm; The connecting part includes: a connector disposed on the side of the diaphragm; a sliding ring slidably disposed on the connector; an insert disposed on the sliding ring; the insert disposed inside a circular hole on the connecting flange; and the insert inserted into the buffer sleeve.

[0006] Furthermore, the main body is provided with threads on its exterior.

[0007] Furthermore, the rotating part includes: a rotating element and a rotating groove; The rotating component is configured as a circular ring structure; the inner wall of the rotating component is provided with threads, and the rotating component is mounted on the main body; the rotating groove is opened inside the rotating component; the inner wall of the rotating groove is provided with rectangular protrusions.

[0008] Furthermore, the diaphragm is configured with a hexagonal structure; a circular hole is provided in the middle of the diaphragm; the circular hole on the buffer sleeve corresponds to the circular hole on the connecting flange; and the circular hole on the buffer sleeve corresponds to the circular hole on the connector.

[0009] Furthermore, the plug is inserted inside the rotating groove; the plug contacts a rectangular protrusion on the inner wall of the rotating groove.

[0010] Furthermore, the connecting part also includes: a spring; The spring is fixedly connected to the sliding ring; the spring is fixedly connected to the connecting piece; the spring is fitted onto the insert.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this device, an insert and a rotating ring are provided. The insert is fixedly connected to the sliding ring, while the rotating ring is set on the main body. Thus, during use, pulling the sliding ring causes the insert to move and stretch the spring. By installing the diaphragm between the connecting flange and the connector, and with the buffer sleeve corresponding to the round holes on the connecting flange and the connector, the spring's reset action causes the insert to be inserted into the round holes of the buffer sleeve and the connecting flange, allowing the insert to be inserted into the rotating groove, completing the connection of the main body, diaphragm, and connector. By manually adjusting the rotating component, the rectangular protrusion inside the rotating groove contacts the insert, and friction is generated during contact. Applying friction grease or similar products increases the friction, completing the quick connection. Attached Figure Description
