Technical Field
The utility model relates to a modular seal bush.
Background
A bushing is a component that functions as a gasket placed in a base or valve body through which a shaft or valve cartridge passes. Due to the variety of depth dimensions of the base or valve body, the length dimension of the bushing needs to be customized. If a bush is involved, the length can be adjusted, and the bush can be applied to various bases or valve bodies with different depth specifications.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a modular sealed bush can adjust length according to the demand to satisfy the base or the valve body of the different degree of depth specifications.
In order to achieve the purpose, the technical scheme of the utility model is to design a combined sealing bush, which comprises a first bush component, a second bush component and a third bush component;
the first lining assembly is of a sleeve structure, an annular boss extending outwards is arranged at the lower part of the first lining assembly, and external threads are arranged on the outer wall of the upper part of the first lining assembly; the second bushing component is of a lantern ring structure, and internal threads are arranged on the inner wall of the second bushing component; the third lining assembly is of a sleeve structure, and external threads are arranged on the outer walls of two ends of the third lining assembly; the inner diameter and the outer diameter of the first bushing assembly are the same as those of the third bushing assembly, the external thread shapes of the first bushing assembly and the third bushing assembly are the same, and the thread tail end of the first bushing assembly can be connected with the thread front end of the third bushing assembly; the second bushing assembly inner diameter is equal to the outer diameter of the first and third bushing assemblies, and the second bushing assembly is threadably connected to the first and third bushing assemblies at the external threads.
Further, a composite seal bushing also includes a gasket; the gasket has a plurality of, overlaps one by one and establishes the outer wall at first bush subassembly and third bush subassembly.
Further, the outer diameter of the second bushing assembly is equal to the diameter of the annular boss at the lower part of the first bushing assembly, and the outer diameter of the second bushing assembly and the diameter of the annular boss at the lower part of the first bushing assembly are slightly smaller than the outer diameter of the gasket; the inner diameter of the washer is larger than or equal to the outer diameters of the first bushing assembly and the third bushing assembly, and the inner diameter of the washer is smaller than the outer diameter of the second bushing assembly and the diameter of the annular boss at the lower part of the first bushing assembly.
Further, the inner walls of the first bushing assembly and the third bushing assembly are coated with a high-strength scratch-resistant coating.
The utility model has the advantages and the beneficial effects that: the utility model relates to a modular seal bush can adjust length according to the demand to satisfy the base or the valve body of different degree of depth specifications.

Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example (b):
referring to fig. 1, a combined sealing bush comprises a first bush component 1, a second bush component 2, a third bush component 3 and a gasket 4;
the first bushing component 1 is of a sleeve structure, an annular boss extending outwards is arranged at the lower part of the first bushing component 1, and external threads are arranged on the outer wall of the upper part of the first bushing component 1; the second bushing component 2 is of a lantern ring structure, and internal threads are arranged on the inner wall of the second bushing component 2; the third lining component 3 is of a sleeve structure, and external threads are arranged on the outer walls of two ends of the third lining component 3; the inner diameter and the outer diameter of the first bushing assembly 1 are the same as those of the third bushing assembly 3, the external thread shapes of the first bushing assembly 1 and the third bushing assembly 3 are the same, and the thread tail end of the first bushing assembly 1 can be connected with the thread front end of the third bushing assembly 3; the second liner assembly 2 has an inner diameter equal to the outer diameter of the first and third liner assemblies 1 and 3, and the second liner assembly 2 is threadably connected to the outer threads of the first and third liner assemblies 1 and 3.
As shown in fig. 2, the washers 4 are firstly sleeved on the outer wall of the first bushing assembly 1 one by one, so that the external thread of the first bushing assembly 1 is just exposed, one second bushing assembly 2 is screwed to the external thread of the first bushing assembly 1, then one third bushing assembly 3 is screwed into the second bushing assembly 2, then the plurality of washers 4 are sleeved on the outer wall of the third bushing assembly 3, the external thread of the third bushing assembly 3 is just exposed, and finally one second bushing assembly 2 is screwed to the external thread of the third bushing assembly 3. (if the depth of the base/valve body is increased, this may continue to increase the number of second and third bushing assemblies 2 and 3.)
Because the outer diameter of the second bushing assembly 2 is equal to the diameter of the annular boss of the lower portion of the first bushing assembly 1, and the outer diameter of the second bushing assembly 2 and the diameter of the annular boss of the lower portion of the first bushing assembly 1 are slightly smaller than the outer diameter of the washer 4, the inner diameter of the washer 4 is greater than or equal to the outer diameters of the first bushing assembly 1 and the third bushing assembly 3, and the inner diameter of the washer 4 is smaller than the outer diameter of the second bushing assembly 2 and the diameter of the annular boss of the lower portion of the first bushing assembly 1. Therefore, the annular boss of the lower portion of the first liner assembly 1 and the second liner assembly 2 restrain the washer 4 to the outer walls of the first liner assembly 1 and the third liner assembly 3.
The inner walls of the first and third bushing assemblies 1 and 3 are coated with a high-strength scratch-resistant coating.
As fig. 3, will the utility model discloses place in the base B, axle A passes the utility model discloses, make simultaneously because the existence of packing ring 4 the utility model discloses can be firm fix in base B.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
