Embodiment 1

[0029] A buckle-connected water pump impeller, comprising a rear cover 1, a front cover 2 and impeller blades 3, the impeller blades 3 are fixed to the rear cover 1, and the impeller blades 3 are away from the side of the rear cover 1 A plurality of slots are provided, and the front cover 2 is provided with buckles 4 corresponding to the slots one by one. connect. The rear cover 1 and the front cover 2 are connected through the buckle 4 and the card slot. The structure is firm, the positioning is accurate, and it is not loose. Compared with the conventional plastic impeller structure, the front and front cover 2 adopts an ultrasonic welding structure, and the welding size is smaller. Accurate, with better reliability, in terms of processing technology, the buckle 4 can be integrally injection molded with the front cover 2, with high dimensional accuracy. The impeller blades 3 are integrally formed with the rear cover plate 1 . The dimensional accuracy and structural reliabil...

Abstract

The invention relates to the technical field of water pump accessory structures, in particular to a water pump impeller connected in a buckled mode. The impeller comprises a rear cover plate, a frontcover plate and impeller blades, wherein the impeller blades are fixed to the rear cover plate, a plurality of clamping grooves are formed in the sides, away from the rear cover plate, of the impellerblades, buckles matched with the clamping grooves in a one-to-one correspondence mode are arranged on the front cover plate, and the front cover plate and the impeller blades are mutually connected through one-to-one matching of the buckles and the clamping grooves. According to the water pump impeller connected in the buckled mode, the rear cover plate and the front cover plate are connected ina matched mode through the buckles and the clamping grooves, the structure is firm, positioning is accurate, looseness is avoided, compared with the structure that an ultrasonic welding is adopted bythe front cover plate in a conventional plastic impeller structure, the welding size is more accurate, better reliability is achieved, in the machining process, the buckles and the front cover plate can be integrally formed in an injection molding mode, and the size precision is high.

Description

technical field [0001] The invention relates to the technical field of water pump accessory structures, in particular to a snap-fit ​​connection of a water pump impeller. Background technique [0002] The impeller is the core component of the water pump. The motor drives the impeller to rotate, so that the blades of the impeller rotate, so that the water in the water pump is sent to a high place under the centrifugal action of the blade rotation. The blades of the impeller in the prior art are fixed on the back cover. The impeller and the back cover are die-cast directly through the mold, and then the back cover is connected to the blade and the front cover through ultrasonic welding to assemble the impeller; ultrasonic welding requires ultrasonic welding equipment, the process is complicated, and the welding Dimensions are imprecise and reliability is difficult to control. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
