Clutch hub for sprayer

Abstract

The utility model discloses a clutch hub for a sprayer, which comprises a clutch hub shell, the shell is a round body, the clutch hub adopting the structure and the clutch hub shell are of an integrated structure, a through hole is formed in the inner ring part of the shell, the preprocessing of a shaft tube hole in the prior art is canceled, and the clutch hub is convenient to assemble and disassemble. And the step of welding the shaft tube hole and the hub shell is omitted, so that the defective rate caused by welding is avoided, the machining efficiency of the clutch hub is improved, and the machining cost is reduced.

Description

Technical Field

[0001] The utility model relates to a clutch hub, in particular to a clutch hub used for a sprayer. Background Art

[0002] The clutch hub commonly installed at the output end of the gasoline engine is an important component of a backpack mist sprayer or atomizer, and is also called a driving sleeve. The clutch hub has the same function as the clutch hub in the disclosed patent document CN217615395U. In the conventional structure of the disclosed clutch hub, the structure of the clutch hub is as follows: Figure 1 As shown in the figure, the central shaft tube hole of the clutch hub is fixed at the center position of the clutch hub body by welding, and the shell and the central shaft tube hole of the clutch hub are split structures. This welding connection method has prominent structural disadvantages, complex processing methods, high costs, and low processing efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a clutch hub with an improved structure, which can bring higher working efficiency and lower production costs through the improved processing technology, and the clutch hub structure is simpler and stronger.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A clutch hub for a sprayer, comprising a clutch hub shell, characterized in that the shell is a circular body having an outer ring portion, an inner ring portion and a radially extending plane portion connecting the outer ring portion and the inner ring portion, the diameter of the outer ring portion being greater than the diameter of the inner ring portion, and the center of the inner ring portion having a through hole.

[0006] Furthermore, four penetration holes are arranged on the radially extending plane portion.

[0007] Furthermore, the outer ring portion, the inner ring portion and the radially extending plane portion are an integrated structure.

[0008] The clutch hub adopts the above structure, and the three parts of the hub shell are an integrated structure. The inner ring part of the shell forms a through hole, which eliminates the pre-processing of the shaft tube hole in the prior art, and the welding step of the shaft tube hole and the hub shell. In this way, there is no defective rate caused by welding, which improves the processing efficiency of the clutch hub and reduces the processing cost. On the other hand, the structure of the integrated clutch hub is simpler and stronger, and can achieve the necessary strength required by the clutch hub. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 A cross-sectional view of a clutch hub of an existing welded structure;

[0010] Figure 2 This is a schematic diagram of the clutch hub structure of the utility model;

[0011] Figure 3 It is a cross-sectional view of the clutch hub of the utility model. DETAILED DESCRIPTION

[0012] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0013] like Figure 2 , 3 As shown, a clutch hub for a sprayer includes a clutch hub housing 1, the housing 1 is a circular body, the circular body has an outer ring part 11, an inner ring part 12 and a radially extending plane part 13 connecting the outer ring part 11 and the inner ring part 12, the outer ring part 11 has a diameter greater than the inner ring part 12, the inner ring part 12 has a through hole 2 at the center, and the inner ring part and the outer ring part are connected. Four through holes 3 are arranged on the radially extending plane part 13.

[0014] The outer ring portion 11, the inner ring portion 12 and the radially extending plane portion 13 are an integral structure. The inner ring portion 12 and its central through hole 2 are formed by multiple extrusion steps of a progressive die and finally stretched.

[0015] In some fields, the clutch hub involved in the present invention is also called a driving sleeve.

[0016] The above description is only a preferred implementation mode of the utility model, and does not impose any form of limitation on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.

Claims
