Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

First embodiment: referring to fig. 1-2, an automobile water pump belt pulley convenient to assemble comprises a mounting ring 10, wherein the mounting ring 10 is cylindrical, and a through hole is formed in the center point of the mounting ring 10 along the height direction of the mounting ring 10 and is used for being connected with an automobile water pump.

In the present embodiment, four connection members are provided on the outer peripheral side of the setting ring 10, and a toothed plate 13 engaged with the belt is provided at one end of each connection member away from the setting ring 10;

further, one end of each connecting member is fixedly connected to the outer circumferential side of the setting ring 10, and the other end is fixedly connected to the corresponding toothed plate 13.

The connecting assembly comprises a supporting plate 11 arranged on the outer periphery side of the placement ring 10, one end of the supporting plate 11 far away from the placement ring 10 is connected with an extension plate 12 in a sliding manner, and the extension plate 12 is fixedly connected with a toothed plate 13;

the part of the supporting plate 11, which is positioned on the supporting plate 11 and far away from the placement ring 10, is provided with a first bolt hole, the extending plate 12 is provided with a plurality of second bolt holes matched with the first bolt hole, the second bolt holes are arranged at equal intervals along the length direction of the extending plate 12, and the first bolt holes are connected with the second bolt holes through bolts.

Further, reinforcing ribs are provided between the extension plate 12 and the corresponding toothed plate 13.

Further, two flat end surfaces of the two toothed plates 13 along the height direction are respectively provided with a clamping groove, and two other flat end surfaces of the two toothed plates 13 along the height direction are respectively integrally formed with a convex block, and the four clamping grooves are in one-to-one correspondence with the convex blocks.
