Mounting structure for engagement of sleeves

Abstract

A mounting structure for engagement of sleeves has an outer sleeve and an inner sleeve. The outer sleeve is mounted around the inner sleeve and has an outer surface. The inner sleeve has an isolating slot and may have at least one functionary element. The isolating slot is defined in the inner sleeve between the inner surface and the outer surface of the outer sleeves and has a depth. When an appropriate force is applied to the outer surface of the outer sleeve to make the sleeves deform to engage with each other, the deformation of the inner sleeve will stop by the isolating sleeve. Therefore the functionary elements mounted inside the inner sleeve will not be damaged.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a side view in partial section of the mounting structure for engagement of sleeves in accordance with the present invention; and

FIG. 2 is an operational side view in partial section of the mounting structure in FIG. 1, showing the inner sleeve and the outer sleeve are deforming when an appropriate force is applied to the mounting portion of the inner sleeve and the distal end of the outer sleeve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1, the mounting structure for engagement of sleeves in accordance with the present invention comprises an inner sleeve (10) and an outer sleeve (20).

The inner sleeve (10) has a mounting end, a chamber (11), a mounting portion (12), an isolating slot (13) and may have multiple functionary elements (110).

The mounting end has a center and an outer edge. The chamber (11) is defined inside the inner sleeve (10) and has an inner surface. The mounting portion (12) is formed on the mounting end of the inner sleeve (10) along the outer edge of the mounting end and has a distal side (121), a proximal side (122) and a notch (120). The notch (120) is defined in the proximal side (122) of the mounting portion (12). The isolating slot (13) is annular and defined in the mounting end of the inner sleeve (10) near the outer edge of the mounting end and has a determined depth. The functionary elements (110) are mounted inside the chamber (11), adjacent to the inner surface of the chamber (11) and may be bearings.

The outer sleeve (20) is mounting around the inner sleeve (10) and has an outer surface and a distal end (21) mounted in the notch (120) of the mounting portion (12).

With reference to FIG. 2, when an appropriate force is applied to the mounting portion (12) of the inner sleeve (10) and the distal end (21) of the outer sleeve (20), the mounting portion (12) and the distal end (21) of the outer sleeve (20) have a deformation and eventually be mounted securely together. Because of the isolating slot (13), the deformations of the mounting portion (12) and the will not deform the chamber (11) of the inner sleeve (10). Consequently, the inner surface of the inner sleeve (10) will not deform simultaneously and the functionary elements (110) mounted inside the chamber (11) may not being damaged.

Additionally, with the defining of the isolating slot (13), the thickness of the inner sleeve (10) is reduced, so that the force need to be applied for deforming the inner sleeve (10) for engagement is decreased.

Claims

1. A mounting structure for engagement of sleeves comprising an inner sleeve having a mounting end having a center; andan outer edge;a chamber being defined inside the inner sleeve and having an inner surface; andan isolating slot being annular and defined in the mounting end of the inner sleeve near the outer edge of the mounting end and having a depth; andan outer sleeve being mounting around the inner sleeve and having an outer surface.

2. The mounting structure as claimed in claim 1, wherein the inner sleeve further has a mounting portion being formed on the mounting end of the inner sleeve along the outer edge of the mounting end and having a distal side;a proximal side; anda notch defined in the proximal side of the mounting portion; andthe outer sleeve has a distal end mounted in the notch of the mounting portion.

3. The mounting structure as claimed in claim 2, wherein the inner sleeve further has at least one functionary element being mounted inside the chamber adjacent to the inner surface of the chamber.

4. The mounting structure as claimed in claim 3, wherein each one of the at least one functionary element is a bearing.
