Description

Technical Field

[0001] This utility model relates to a connecting plate for an air booster pump, belonging to the field of air booster pump technology. Background Technology

[0002] Existing air booster pumps consist of a brake housing, a connecting disc, and an air chamber housing connected in sequence. Traditional connecting discs have multiple sealing rings at their center, resulting in a complex structure, high machining difficulty, low yield, and high production cost. The complex structure also makes them prone to porosity or sand holes during casting, leading to high machining costs and difficulties. Furthermore, the connecting discs are heavy, making production time-consuming and labor-intensive. Therefore, developing a connecting disc for air booster pumps that is simple in structure, low in machining cost, low in material consumption, and has a high yield is crucial. Utility Model Content

[0003] This utility model addresses the shortcomings of the prior art by providing a connecting plate for an air booster pump.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A connecting plate for an air booster pump includes a plate body with a central hole for embedding a brake housing. The plate body is provided with a plug body for connecting to the inner wall of the air chamber housing, and the plug body is provided with a plurality of air chamber connecting lugs for fixed connection to the inner wall of the air chamber housing.

[0006] Furthermore, the central hole is provided with a positioning groove for defining the brake housing.

[0007] Furthermore, the air chamber connecting ear plate is provided with threaded holes.

[0008] Furthermore, the connector has a direct insertion structure.

[0009] Furthermore, the connector is provided with a limiting boss for blocking the air chamber housing.

[0010] Furthermore, a vent is provided between the edge of the disc and the central hole.

[0011] Furthermore, a bracket connection hole for fixing the bracket is provided between the edge of the disc and the central hole.

[0012] Furthermore, the disc body, positioning groove, air chamber connecting ear plate, and plug body are all integrally formed.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the connecting disc of this application adopts the structural optimization of the brake housing with the central hole, which eliminates the central multi-seal ring structure, making its structure simple and easier to cast. It ensures the product yield and improves production efficiency. At the same time, the casting process can effectively avoid the problems of air holes, sand holes and deformation. Several air chamber connecting ear plates are added to the plug body, which effectively reduces material consumption and saves production costs. Attached Figure Description

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figures 1-2 As shown, a connecting disc for an air booster pump includes a disc body 1. The disc body 1 has a central hole 3 for embedding a brake housing. The disc body 1 has an insert body 7 that connects to the inner wall of the air chamber housing. The insert body 7 has several air chamber connecting lugs 6 for fixed connection to the inner wall of the air chamber housing. In application, the brake housing is embedded in the central hole 3 of the disc body 1, and then the insert body 7 is inserted into the air chamber housing for fixed connection. This application's connecting disc uses a structural optimization of embedding the brake housing in the central hole 3, eliminating the need for multiple central sealing rings, simplifying the structure, facilitating better casting, ensuring product yield, improving production efficiency, and effectively avoiding problems such as air holes, sand holes, and deformation during the casting process. The addition of several air chamber connecting lugs 6 to the insert body 7 effectively reduces material consumption and saves production costs.

[0021] The central hole 3 is provided with a positioning groove 4 for defining the brake housing.

[0022] The air chamber connecting lug 6 is provided with threaded holes. The air chamber connecting lug 6 on the plug body 7 is fixedly connected to the inner wall of the air chamber shell.
