Description

Dual-purpose sleeve

The present invention relates to a sleeve, in particular to a dual-purpose sleeve.

Fasteners are used in various products to assemble different components. Examples of fasteners include but are not limited to screws, nuts, bolts, etc. Most of them are locked or loosened by rotation. When rotating, it is usually necessary to put a sleeve on the fastener for use, and the sleeve needs to be inserted into a long force-applying element to perform the rotation operation.

In order to be applicable to fasteners of different sizes at the same time, a multi-size socket has been developed. The known multi-size socket includes a plurality of relatively movable and mutually nested inner and outer sets, and a connecting rod extending from the inner and outer sets for a driving tool (manual or power tool) to be assembled. The inner and outer sets and the connecting rod are both independent components, which are further connected by a fastening member or a stopper such as a C buckle or a ring to further complete the connection between the inner and outer sets and the connecting rod.

It is known that although multi-size sockets can be used for the disassembly and assembly of fasteners of different sizes, their structure is complex, and their assembly and manufacturing are difficult and time-consuming, which has shortcomings that need to be solved urgently.

Therefore, it is necessary to provide a novel and advanced dual-purpose sleeve to solve the above problems.

The main purpose of the present invention is to provide a dual-purpose socket with a simple structure, quick and easy assembly and manufacturing, and applicable to the disassembly and removal of fasteners of different sizes.

To achieve the above-mentioned purpose, the present invention provides a dual-purpose sleeve, comprising: an outer sleeve, comprising a sleeve hole, a receiving hole connected to the sleeve hole, and a radial projection radially disposed between the sleeve hole and the receiving hole; an inner sleeve, inserted into the outer sleeve without relative rotation, comprising an inner sleeve portion and a connecting section plugged into the inner sleeve portion, the inner sleeve portion is received in the sleeve hole and can abut against the radial projection axially, the connecting section extends from the inner sleeve portion toward the receiving hole; and a first elastic member, disposed in the receiving hole, and abutted between the radial projection and the inner sleeve.

The following is only an example to illustrate the possible implementation of the present invention, but it is not intended to limit the scope of protection of the present invention, so it should be stated in advance.

Please refer to Figures 1 to 5, which show an embodiment of the present invention. The dual-purpose sleeve 1 of the present invention includes an outer sleeve 10, an inner sleeve 20 and a first elastic member 30.

The outer sleeve 10 includes a sleeve hole 11, a receiving hole 12 connected to the sleeve hole 11, and a radial projection 13 radially protruding between the sleeve hole 11 and the receiving hole 12. The inner sleeve 20 is inserted into the outer sleeve 10 without relative rotation. The inner sleeve 20 includes an inner sleeve portion 21 and a connecting section 22 plugged with the inner sleeve portion 21. The inner sleeve portion 21 is received in the sleeve hole 11 and can axially abut against the radial projection 13. The connecting section 22 extends from the inner sleeve portion 21 toward the receiving hole 12. The first elastic member 30 is disposed in the receiving hole 12 and abuts against the radial projection 13 and the inner sleeve 20. In this way, the structure is simple, the assembly and manufacturing are fast and easy, and it can be applied to the disassembly of fasteners of different sizes.

The outer sleeve 10 further includes an outer sleeve portion 14 having the sleeve hole 11, the inner sleeve portion 21 being thinner than the outer sleeve portion 14, the sleeve hole 11 of the outer sleeve portion 14 being provided for sleeve connection with a relatively large-sized fastener (such as a nut, bolt, etc.), and a sleeve hole 211 of the inner sleeve portion 21 being provided for sleeve connection with a relatively small-sized fastener, wherein the thicker outer sleeve portion 14 has a greater structural strength for driving a relatively large-sized fastener and is not easily broken. The inner sleeve 21 includes a plug-in end 212, and the connecting section 22 includes a plug hole 221. The plug hole 221 has a radial size equal to or slightly smaller than the plug-in end 212. The plug-in end 212 is tightly plugged into the plug hole 221, so that the inner sleeve 21 and the connecting section 22 can be assembled and connected simply, quickly and stably.

In this embodiment, the plug end 212 is a polygon, and the plug hole 221 is a polygon. However, the plug end 212 and the plug hole 221 can be any other circular or non-circular configurations as long as they can match each other to achieve a tight fit. In detail, the plug end 212 includes a plurality of outer planes 213 and a plurality of corners 214, and the plug hole 221 includes a plurality of inner planes 222 and a plurality of grooves 223. The plurality of outer planes 213 and the plurality of inner planes 222 are tightly fitted, and the plurality of corners 214 are left empty to be accommodated in the plurality of grooves 223.

Preferably, the plug end 212 includes an arc surface 215 that extends into the plug hole 221 and engages with one end of the connecting section 22. The arc surface 215 gradually expands radially toward the outer sleeve 10 to ensure a tight fit and prevent the plug end 212 from being inserted too deeply. In this embodiment, a gap G is provided between an end surface of the plug end 212 and a bottom surface of a hole of the plug hole 221 to avoid incomplete plugging.

The inner sleeve 21 has a smaller diameter than the connecting section 22, and the first elastic member 30 is disposed between the radial protrusion 13 and the inner sleeve 21. Specifically, the first elastic member 30 is a ring spring and is sleeved on the inner sleeve 21. The first elastic member 30 elastically pushes the connecting section 22 so that the sleeve hole 211 of the inner sleeve 21 is normally immersed in the sleeve hole 11 of the outer sleeve 14, which is convenient for quick and direct use of the sleeve hole 11 of the outer sleeve 14 and avoids interference with the inner sleeve 21.

In this embodiment, the dual-purpose sleeve 1 further includes a locking mechanism 40 disposed on the connecting section 22. The locking mechanism 40 can be moved between a locking position (FIG. 4) and a releasing position (FIG. 5). When the locking mechanism 40 is in the releasing position, it allows a plug-in 50 to be inserted into or removed from a connecting hole 224 of the connecting section 22. When the locking mechanism 40 is in the locking position, it locks the plug-in 50 inserted into the connecting hole 224, thereby facilitating quick assembly or replacement. The plug-in 50 is, for example, a connecting rod that can be assembled to a driving tool, or the plug-in 50 can be a driving tool head (e.g., a cross, flat head, or other shaped screwdriver head)

In detail, the connecting section 22 further includes a radial through hole 225 and a radial stop 226 (an integrally formed protrusion or C-clip). The locking mechanism 40 includes a sleeve 41, a second elastic member 42 and a limiting member 43. The sleeve 41 is slidably mounted on the connecting section 22. The sleeve 41 includes an inner stop 411, an inner protrusion 412 and a release groove 413. The inner stop 411 is axially stopped by the radial stop 226. The second elastic member 42 and a limiting member 43 are provided on the connecting section 22. The elastic member 42 is a ring spring and is sleeved on the connecting section 22. The second elastic member 42 is disposed between the connecting section 22 and the inner protrusion 412. The limiting member 43 is accommodated in the radial through hole 225. When the locking mechanism 40 is located at the release position, the limiting member 43 corresponds to the release groove 413 to release the plug-in 50. When the locking mechanism 40 is located at the locking position, the limiting member 43 corresponds to the inner protrusion 412 to lock the plug-in 50.

Preferably, the connecting section 22 further includes an outer convex edge 227, and the sliding sleeve 41 is located between the radial stop 226 and the outer convex edge 227. The sliding sleeve 41 can move to contact the outer convex edge 227, so that the release groove 413 can quickly and accurately align with the limiting member 43 (Figure 5).
