Description

Technical Field

[0001] This utility model relates to the field of coffee machine component technology, specifically a coffee machine shaft fixing base. Background Technology

[0002] As coffee culture becomes increasingly popular globally, the coffee machine market is booming. From early semi-automatic, simple coffee machines, they have evolved into diverse home and commercial models integrating automation and intelligence. The internal structure of coffee machines has become increasingly sophisticated and complex. The spindle, as a key transmission component, bears the heavy responsibility of driving core actions such as grinding and brewing, and its operational stability is directly related to the quality and efficiency of coffee making. The spindle mounting bracket is the key support structure that ensures the spindle's precise and stable operation, making its design optimization inevitable due to industry demands.

[0003] In existing coffee machine spindle mounts, the motor is usually directly inserted into the mount. This results in poor stability between the motor and the mount, causing vibrations between the motor and the mount when rotating at high speeds. This reduces the lifespan of the mount, and the outer edge of the motor is in close contact with the inner edge of the mount, leading to poor heat dissipation. Utility Model Content

[0004] The purpose of this utility model is to provide a coffee machine shaft fixing base, which has the advantages of stable structure and stable connection with internal motor, and solves the problems of poor connection stability and poor heat dissipation performance between the current coffee machine fixing base and the motor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coffee machine shaft fixing base, comprising a housing, the housing comprising a cylinder, the cylinder being a hollow cavity structure, an opening on one side of the cavity structure, and a through hole at the center of the cylinder, two circular holes symmetrically arranged around the through hole, and a plurality of grooves arranged on the outer edge of the cylinder, a plurality of limiting mechanisms being constructed on the inner edge of the cylinder facing the grooves, and a chamfered surface being provided on the upper part of the outer edge of the cylinder, on which two positioning mechanisms are symmetrically installed, and a base is provided at the bottom end of the housing.

[0006] Preferably, the limiting mechanism is provided in three parts, each of which includes a limiting post. One end of the limiting post is connected to the inside of the cylinder, and the other end is flush with the outside of the cylinder and has a protruding post.

[0007] Preferably, the limiting post and the protruding post are provided with a limiting groove on one side near the center of the cylinder. One side of the limiting groove is flush with the end of the protruding post, and the other end extends to the middle of the limiting post, forming a limiting step on the limiting post.

[0008] Preferably, each of the positioning mechanisms includes a positioning plate with an L-shaped vertical cross-section and a protrusion inside the corner of the positioning plate. A short column is constructed at the end of the protrusion away from the cylinder, and a blind hole is opened inside the short column.

[0009] Preferably, the base includes a vertical plate, the top of which is fixedly connected to the lower end face of the cylinder, and a sinking groove is provided on the side of the top of the vertical plate near the groove, and a bottom plate is provided on the side of the bottom of the sinking groove away from the cylinder.

[0010] Preferably, two ribs are symmetrically arranged at the top of the base plate, each rib being a right-angled triangle and fitting against the side of the vertical plate and the base plate.

[0011] Preferably, the base plate has two symmetrical mounting holes on both sides inside, and reinforcing ribs are provided at both ends of the base plate, with chamfering structures provided at the four corners of the reinforcing ribs.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a cylinder, limiting posts, protrusions, and limiting grooves, uses three limiting posts set inside the cylinder, with the protrusions at the ends of the limiting posts connecting to the plastic parts of the coffee machine. The limiting grooves opened on the limiting posts and protrusions facing the cylinder axis enable the motor to engage, improving the stability of the motor after installation. The limiting posts and the motor together create a heat dissipation channel between the outer edge of the motor and the inner edge of the mounting base, improving the heat dissipation performance of the mounting base.

[0014] 2. This utility model, by setting a cylinder, a groove, a bottom plate, ribs and reinforcing ribs, can reduce the wall thickness of the fixing seat and shorten the cooling time of the fixing seat during injection molding by opening a groove on the outer edge of the cylinder and facing the limiting mechanism. The bottom plate set at the top of the bottom plate and connected to the vertical plate can improve the structural strength of the fixing seat. The reinforcing ribs set at both ends of the bottom plate can enhance the structural strength of the bottom plate. Attached Figure Description
