FIG. 1 is a schematic diagram of the present utility model when assembled;
fig. 2 is a schematic diagram of the assembled structure of the present utility model.
The figure shows: a left housing 1; a right housing 2; a pin 3; a female buckle 4; a guide slope 5; a limiting member 6; a bump 7; a positioning column 8; a positioning hole 9; a screw hole 10; a stud 11; a reinforcing rib edge 12; a reinforcing rib 13; a sealing strip 14.
Detailed Description
Embodiments of the utility model: as shown in fig. 1 to 2, an assembled fan volute comprises a left shell 1 and a right shell 2 which are mutually spliced, wherein the left shell 1 and the right shell 2 are injection molded plastic parts, the left shell 1 comprises a plurality of male buckles 3 extending towards the right shell 2, the right shell 2 comprises corresponding female buckles 4, the male buckles 3 and the female buckles 4 are distributed along the splicing surfaces of the two, compared with the prior art, the assembled fan volute only uses the two parts of the left shell 1 and the right shell 2 to carry out clamping and assembling, compared with the prior art, the assembled fan volute has the advantages of reduced number of parts, reduced cost and integrated body, improved production efficiency, and convenience for the alignment and matching of the left shell 1 and the right shell 2, the right shell 2 comprises a plurality of limiting parts 6 with guiding inclined planes 5 which are convenient to extend towards the left shell 1, the upper end and the lower end of the limiting parts of the left shell 1 are at least contacted to achieve the limiting effect during the alignment and matching, and the guiding inclined planes 5 of the limiting parts 6 play a guiding role in the alignment and matching process, so that the matching of the two parts is more convenient.
As a preferred mode, the left shell 1 and the right shell 2 comprise a plurality of corresponding protruding blocks 7, the corresponding protruding blocks 7 are provided with matched positioning columns 8, positioning holes 9, matched screw holes 10 and studs 11, when the left shell 1 and the right shell 2 are aligned and matched, the positioning columns 8 on the two protruding blocks 7 are in plug-in fit with the positioning holes 9, the studs 11 are aligned with the screw holes 10, and then the two protruding blocks are screwed and fixed by using screws, so that the two protruding blocks are stably connected.
As a preference, the splicing part of the left shell 1 and the right shell 2 is provided with a reinforcing rib edge 12, the surfaces of the left shell 1 and the right shell 2 are provided with reinforcing ribs 13, the strength of the left shell 1 and the right shell 2 is improved, and the male buckle 3, the female buckle 4, the limiting piece 6 and the protruding block 7 are all positioned on the reinforcing rib edge 12 or the reinforcing ribs 13, so that the left shell 1 and the right shell 2 have stronger connection strength and are not easy to break.
Preferably, a sealing strip 4 is arranged at the splicing position of the left shell 1 and the right shell 2, so that the matched tightness is improved, and air leakage of the left shell and the right shell at the splicing position is prevented.
