Sleeve structure

The present invention is a sleeve structure, which mainly refers to a joint stability and easy rotation operation of the sleeve and the sleeve member, and can prevent deformation of the end angle of the sleeve member.

Referring to FIG. 8 , the conventional sleeve 1 ′ is provided with a hollow sleeve hole 11 ′, and the sleeve hole 11 ′ protrudes from the inner wall with six inwardly protruding curved portions 12 ′, and between the curved portions 12 ′ With a spacer 13', the sleeve 11' can be fitted with a hexagonal sleeve 2' (such as a bolt, a nut, etc.), and the sleeve 11' is slightly larger than the hexagonal sleeve 2'. The sleeve body 1' is positionally engageable with the end portion 21' of the hexagonal fitting 2' by the spacing portion 13' of the sleeve hole 11'.

As shown in FIG. 9, when the sleeve 1' is rotated to drive the hexagonal sleeve 2', the sleeve hole 11' will be slightly offset from the position of the corresponding hexagonal sleeve 2', and the curved surface of the curved portion 12' will be The side is in contact with the end angle 21' of the hexagonal fitting 2' (Fig. a), so that the surface and the surface fitting manner have poor joint stability, and the strength of the sleeve 1' which is heat treated is generally higher. The strength of the hexagonal sleeve 2' is good, so if the hexagonal sleeve 2' is in the tightened state, the larger torque must be applied to rotate the sleeve 1' to drive the hexagonal sleeve 2' to rotate, thus easily causing the figure 10 The end corner 21' of the illustrated hex fitting 2' is slidably worn and causes the sleeve 1' to not rotate the hex fitting 2'.

The purpose of the present invention is to provide a joint stability and easy rotation operation for the sleeve and the sleeve, and to prevent deformation of the end angle of the sleeve member.

The center of the sleeve of the present invention has a set of holes, and the inner wall of the set of holes is provided with six correspondingly shaped convex portions at intervals of 60 ,, and the adjacent convex portions have concave portions corresponding to the shape, and the convex portions are further The axial end portion is provided with a guiding oblique side, and a central plane portion is further disposed on a side of the convex portion facing the center of the sleeve hole, and the central plane portion is provided with a side plane portion having an obtuse angle with the central plane portion, and two adjacent convex portions are disposed The side planar portion is parallel; the partition portion has a concave flat portion, and the two concave flat portions are coupled to the side flat portion of the convex portion.

The sleeve of the creation sleeve can be fitted with a hexagonal sleeve. When the sleeve is rotated, the surfaces of the six central plane portions respectively abut against the six surfaces of the hexagonal sleeve member, and the obtuse angles of the six protrusions can be respectively The six surfaces of the hexagonal fitting can be abutted against the surface and the surface and the corner to enhance the anti-slip effect, and the end angle of the hexagonal fitting can be prevented from being deformed, and the rotation of the sleeve can be greatly improved. Torque, labor-saving operation and reliability, the sleeve of this creation can also be fitted with hexagonal or triangular fittings, not necessarily hexagonal, and has better applicability.

Referring to Figures 1 and 2, the sleeve 1 of the present invention has a sleeve hole 11 extending therethrough. The sleeve wall 11 is provided with six correspondingly shaped protrusions 12 at intervals 60 ,, and the adjacent protrusions 12 are arranged. a concave partition portion 13 having a corresponding shape, and a guide bevel 120 is disposed at an axial end of each convex portion 12, and a central flat portion 121 is disposed on a central side of the convex portion 12 toward the sleeve hole 11, the central flat portion 121 The side plane portion 122 having the obtuse angle 123 of the central flat portion 121 is disposed on the side, and the side flat portion 122 of the two adjacent convex portions 12 is parallel, which can have an average force effect; and the partition portion 13 has a concave flat portion 131. Both sides of the concave flat portion 131 are coupled to the side flat portion 122 of the convex portion 12.

Referring to FIG. 3, the sleeve hole 11 of the creation sleeve 1 can fit the hexagonal sleeve member 2, and the end corners 21 of the hexagonal sleeve member 2 are respectively embedded in the six spacer portions 13 and the hexagonal sleeves are assembled. The six surfaces 22 of the piece 2 correspond to and are located near the six central plane portions 121, respectively, and the guide bevel 120 of the present invention can enhance the convenience of the nesting.

Referring to FIG. 4, the partial surface 22 of the six central planar portions 121 respectively abuts the six surfaces 22 of the hexagonal fittings 2 when the sleeve 1 is rotated, and the obtuse angles 123 of the six convex portions 12 are respectively respectively The six surfaces 22 of the hexagonal ferrule 2 can be abutted against the surface and the surface and the corner to enhance the anti-slip effect, and the end angle 21 of the hex fitting 2 can be prevented from being deformed, which can be greatly improved. The rotating torque of the sleeve 1, the labor-saving operation and the reliability.

The present invention can be engaged with the hexagonal sleeve 2 by the surface of the sleeve 1 and the surface and the corner abutment. Therefore, when the end angle 21 of the hexagonal sleeve 2 is worn as shown in FIG. 5, the sleeve 1 can also be used. The six central flat portions 121 and the six obtuse angles 123 respectively abut against the six surfaces 22 of the hexagonal fitting 2 and abut against the hexagonal fitting 2 which can smoothly rotate the disintegrating teeth.

Referring to Figures 6 and 7, the sleeve 1 of the present invention can also be fitted with a hexagonal star fitting 3 or a triangular fitting 4, which does not necessarily have to be a regular hexagonal body, and has better applicability.

Therefore, according to the above, the creation can improve the joint stability of the sleeve and the sleeve, the rotation operation is easy, and the end angle deformation effect of the sleeve is prevented, and the foregoing embodiment is an example of the creation, and is not a limitation of the creation. Equivalent changes based on the spirit of this creation should also fall within the scope of this creation.
