A diaphragm mounting structure for a water pump

Abstract

This utility model discloses a diaphragm installation structure for a water pump, including a mounting base, a connecting rod, a diaphragm, a mounting cover, and a positioning installation structure. When installing the diaphragm, the diaphragm is fitted onto the connecting head, and then the connecting head is inserted into the connecting rod, causing the positioning plate to adhere to the surface of the backing plate, thereby pushing the diaphragm and fixing it to the connecting head. Simultaneously, the positioning head is pressed into the positioning port, ensuring the diaphragm is installed in a centered position. Next, the insert rod is pushed, causing the push port to move, and then the limiting head is pushed. The limiting head moves out of the connecting head and inserts into the limiting port. Then, the insert rod is rotated so that the threaded head is threadedly connected to the connecting head, thus fixing the insert rod inside the connecting head. The limiting head is then engaged in the limiting port, thus fixing the connecting head in the connecting rod. This facilitates diaphragm installation and prevents diaphragm misalignment during installation.

[0007] Preferably, when the limiting head is located at one end of the push port, the limiting head protrudes from the surface of the connector head; when the limiting head is located at the other end of the push port, the limiting head can retract into the interior of the connector head.

[0008] Preferably, there are two limiting heads, which are symmetrically arranged inside the connector.

[0009] Preferably, a retaining ring is provided at the connection between the connector and the insertion rod, and the retaining ring is elastic.

[0010] Preferably, the positioning plate is provided with a positioning port, and the backing plate is provided with a positioning head.

[0011] Preferably, the connector end is provided with a spring, and the spring end is fixed with a fixing plate.

[0012] Preferably, after the connector is inserted into the connecting rod, the spring is in a fully compressed state.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When installing the diaphragm, place the diaphragm onto the connector head, then insert the connector head into the connecting rod, so that the positioning plate and the backing plate surface are in contact, thereby pushing the diaphragm and fixing it on the connector head. At the same time, the positioning head is pressed into the positioning hole to ensure that the diaphragm is installed in the center. Then, push the insert rod to drive the push port, and then push the limit head. The limit head moves out of the connector head and inserts into the limit hole.

[0021] Specifically, the diaphragm 3 is connected to the connecting rod 2 and fixed in the mounting base 1. The mounting cover 4 is pressed onto the mounting base 1 and fixed with bolts to achieve the installation and fixation of the diaphragm 3.

[0022] Please see Figure 2 and Figure 3This utility model provides a diaphragm mounting structure for a water pump. The positioning mounting structure 5 includes a limiting port 51, a limiting port 51 is opened in the connecting rod 2, a connector head 52 is inserted into the connecting rod 2, a positioning plate 53 is fixed on the surface of the diaphragm 3, a backing plate 54 is integrally formed on the surface of the connecting rod 2, an insert rod 55 is slidably connected in the connector head 52, a push port 56 is provided on the insert rod 55, a limiting head 57 is provided in the connector head 52, and a threaded head 58 is slidably connected on the insert rod 55.

[0023] When the limiting head 57 is located at one end of the push port 56, the limiting head 57 protrudes from the surface of the connector 52. When the limiting head 57 is located at the other end of the push port 56, the limiting head 57 can retract into the connector 52. There are two limiting heads 57, which are symmetrically arranged inside the connector 52, resulting in a better locking effect.

[0024] A retaining ring 59 is provided at the connection between the connector 52 and the insert rod 55. The retaining ring 59 is elastic. After the insert rod 55 is pushed into the connector 52, the retaining ring 59 is compressed, making the connection between the connector 58 and the connector 52 more stable.

[0025] The positioning plate 53 is provided with a positioning port 510, and the backing plate 54 is provided with a positioning head 511. When the positioning plate 53 is attached to the surface of the backing plate 54, the positioning head 511 moves into the positioning port 510, which can ensure that the diaphragm 3 is installed in the center and avoids cost.

[0026] The connector 52 is equipped with a spring 512 at its end, and a fixing plate 513 is fixed to the end of the spring 512. After the connector 52 is inserted into the connecting rod 2, the spring 512 is in a fully compressed state, which ensures high connection stability of the connector 52 when the connecting rod 2 moves.

[0027] Specifically, when installing the diaphragm 3, the diaphragm 3 is placed on the connector 52, and then the connector 52 is inserted into the connecting rod 2, so that the positioning plate 53 and the surface of the backing plate 54 are in contact, thereby pushing the diaphragm 3 and fixing the diaphragm 3 on the connector 52. At the same time, the positioning head 511 is pressed into the positioning port 510 to ensure that the diaphragm 3 is installed in the center. Then, the insertion rod 55 is pushed to drive the push port 56, and then the limiting head 57 is pushed. The limiting head 57 moves out of the connector 52 and inserts into the limiting port 51. Then, the insertion rod 55 is rotated so that the threaded head 58 is threadedly connected to the connector 52, so that the insertion rod 55 is fixed inside the connector 52. By the limiting head 57 being inserted into the limiting port 51, the connector 52 is fixed in the connecting rod 2, thus achieving convenient installation of the diaphragm 3 and preventing the diaphragm 3 from being misaligned during installation.
