Abstract
A barrel adjustment and retaining assembly includes a barrel body having an end surface, a seat body having a protrusion, a limiting component and an adjustment barrel. The seat body is movable relative to the barrel body. The protrusion is moved toward the end surface when the seat body moves from a pre-assembly position to an assembly position. The limiting component is clamped between the protrusion and the end surface to deform such that an outer diameter of the limiting component is increased when the seat body moves from the pre-assembly position to the assembly position. The adjustment barrel is sleeved slidably on the barrel body. The clamped limiting component is confined within a hole portion of the adjustment barrel.
Claims10
A barrel adjustment and retaining assembly, comprising:
- a barrel body having an end surface, an outer surface, an inner surface and an internal thread that is formed on said inner surface;
- a seat body having a protrusion that is registered with said end surface of said barrel body, an outer surrounding surface and an external thread that is formed on said outer surrounding surface and that is configured to engage said internal thread of said barrel body such that said seat body is movable relative to said barrel body between a pre-assembly position and an assembly position, said protrusion of said seat body being moved toward said end surface of said barrel body when said seat body moves from said pre-assembly position to said assembly position;
- a limiting component disposed between said protrusion of said seat body and said end surface of said barrel body such that when said seat body is in said pre-assembly position, said limiting component has a normal outer diameter, and when seat body is in said assembly position, said limiting component deforms to have an operating outer diameter greater than said normal outer diameter;
- and
- an adjustment barrel sleeved slidably on said outer surface of said barrel body, and having an end surface, a large diameter hole portion that is spaced apart from said end surface of said adjustment barrel and that has a large diameter, a small diameter hole portion that is disposed between said large diameter hole portion and said end surface of said adjustment barrel and that has a small diameter smaller than said large diameter, and a shoulder surface that is formed between said large diameter hole portion and said small diameter hole portion;
- wherein when seat body is in said assembly position, said operating outer diameter of said limiting component is greater than said small diameter of said small diameter hole portion so that said shoulder surface of said adjustment barrel is movable to abut against said limiting component to thereby limit said limiting component to move in said large diameter hole portion.

A method for assembling a barrel adjustment and retaining assembly, comprising the steps of:
- (a) preparing a barrel body, a seat body, a limiting component and an adjustment barrel, the barrel body having an end surface, an inner surface and an internal thread that is formed on the inner surface, the seat body having a protrusion, an outer surrounding surface and an external thread that is formed on the outer surrounding surface, the limiting component being deformable, the adjustment barrel having an end surface, a large diameter hole portion that is spaced apart from the end surface of the adjustment barrel and that has a large diameter, a small diameter hole portion that is disposed between the large diameter hole portion and the end surface of the adjustment barrel and that has a small diameter smaller than the large diameter of the large diameter hole portion, and a shoulder surface that is formed between the large diameter hole portion and the small diameter hole portion.
- (b) threading the internal thread of the barrel body on the external thread of the seat body to move the seat body to a pre-assembly position such that the limiting component is disposed between the protrusion 31 of the seat body 3 and the end surface 21 of the barrel body 2 and has a normal outer diameter;
- (c) sleeving the adjustment barrel on the seat body and the barrel body such that the limiting component is disposed in the large diameter hole portion;
- and
- (d) threading the internal thread of the barrel body on the external thread of the seat body to move the seat body to an assembly position such that the limiting component is clamped between the protrusion of the seat body and the end surface of the barrel body to deform to have an operating outer diameter greater than the normal outer diameter and greater than the small diameter of the small diameter hole portion so that the shoulder surface of the adjustment barrel is movable to abut against the limiting component to thereby limit the limiting component to move in the large diameter hole portion.
