Abstract

The invention discloses a sleeve suitable for connecting a driving tool and a fixed element. The sleeve comprises a socket ring and a sleeve joint ring, wherein the socket ring is made of metal and comprises a driving part and a driven part which are connected. The driving part is driven by the driving tool and provided with a non-circular driving inner circumferential surface. The driven part is suitable for driving the fixed element and provided with a non-circular driven inner circumferential surface and a driven outer circumferential surface. The sleeve joint ring is made of metal and sleeved on the driven outer circumferential surface. The sleeve has the advantages that: due to the reinforcement of the sleeve joint ring, the deformation of the driven part is reduced during use, and the driven part is not easily damaged; and the sleeve has strong structural strength and durability.

Description

Sleeve

Technical field

The present invention relates to a kind of sleeve, particularly relate to a kind of durable sleeve of using.

Background technology

Fig. 1 shows a sleeve 1 in the past, and this sleeve 1 has cross section and is a non-circular drive hole 11 and a driven hole 12, and this drive hole 11 can drive for a spanner 101, and this driven hole 12 can drive a screw 102.When but this sleeve 1 has been used of a specified duration or born too large pressure, can split because material is tired in the turning point 121 of these driven hole 12 outer peripheral faces, very cause damage.Even with this sleeve 1, be applied to automated system, and while operating in a large number, this sleeve 1 just needs every several days to replace, and has the disappearance of structural strength deficiency.

If improve this disappearance, need to make this sleeve with more expensive material, but so but can produce the disappearance of manufacturing cost costliness.

Summary of the invention

The object of the invention is a kind of enough structural strength is provided and can save manufacturing cost sleeve.

Sleeve of the present invention is applicable to connect a driven tool and a retaining element, and comprise one be made of metal accept ring, it is characterized in that:

This accepts ring, and comprises a drive division and the follower being connected.This drive division is applicable to drive for this driven tool, and has one and be non-circular driving inner peripheral surface.This follower is applicable to drive this retaining element, and has one and be non-circular driven inner peripheral surface, and a driven outer peripheral face.This sleeve also comprises a cover T-Ring being made of metal, and this socket ring set is arranged at this driven outer peripheral face.

Beneficial effect of the present invention is the reinforcement of this cover T-Ring, allows this follower deflection while using reduce, and not fragile, the structural strength of this sleeve is stronger, comparatively durable.

The specific embodiment

Below in conjunction with drawings and Examples, the present invention is described in detail:

Consult Fig. 2, the preferred embodiment of sleeve of the present invention is applicable to connect a driven tool and a retaining element (not shown), this driven tool can be spanner, pneumatic tool or electric tool or automatic machinery, and this retaining element can be the retaining elements such as screw, nut.This sleeve comprises one and accepts 3 and cover T-Rings 4 of ring.

Consult Fig. 3, Fig. 4, Fig. 5, this is accepted ring 3 and is made of metal, and comprises a drive division 31 and the follower 32 being connected.This drive division 31 is applicable to drive for this driven tool, and has one and be non-circular driving inner peripheral surface 311, and one drives outer peripheral face 312.This driving inner peripheral surface 311 defines a cross section and is tetragonal drive hole 313, and this driving inner peripheral surface 311 forms two blocking holes 314 that extend to this driving outer peripheral face 312.

This follower 32 is applicable to drive this retaining element, and has one and be non-circular driven inner peripheral surface 321, a driven outer peripheral face 322, and a driven end face 323 that connects this driven inner peripheral surface 321 and driven outer peripheral face 322.This driven inner peripheral surface 321 defines a cross section and is hexagonal driven hole 329, this driven outer peripheral face 322 have relative one section of first blocking section 324 and one section of second blocking section 325, one section from these the first blocking section 324 inner peripherals, towards this second blocking section 325, expand gradually the driven conical cylinder section 326 extending, one section of driven spacing section 327 of being connected driven conical cylinder section 326 and this second blocking section 325, and one section of driven section 328 of extending to this driven end face 323 from these the first blocking section 324 outer peripheral edges.

This cover T-Ring 4 is made by the metal different with accepting ring 3, comprise that a cover is arranged at the open end face 42 of the socket inner peripheral surface 41 of this driven outer peripheral face 322, this driven end face 323 of vicinity, and contrary this opening end face 42 and prop up this second blocking section 325 keep out end face 43.

This socket inner peripheral surface 41 has one section and props up 411, one sections of card sections are kept out to end face 43 to card section 411 inner peripherals towards this from this expand gradually the socket conical cylinder section 412 that extends, a section and keep out spacing section 413, one sections of sockets that end face 43 extends from this socket conical cylinder section 412 towards this and expand and extend to this lead segment of keeping out end face 43 414 gradually for spacing section 413 from this socket of this first blocking section 324, and one section extends to the socket section 415 of this opening end face 42 to blocking section 411 outer peripheral edges from this.These socket conical cylinder section 412 covers are arranged at this driven conical cylinder section 326, spacing section 413 cover of this socket is arranged at this driven spacing section 327, this socket section 415 covers are arranged at this driven section 328, this first blocking section 324 with to the length of card sections 411 all between 0.05 millimeter to 0.1 millimeter.

Utilize this first blocking section 324, the second blocking section 325, to card section 411, keep out the clamping structure of end face 43, when assembling, this cover T-Ring 4 is directly just knocked in and can be had good combined effect towards the left side from the right.

In sum, sleeve of the present invention has following beneficial effect:

One, the reinforcement of this cover T-Ring 4, allows these driven inner peripheral surface 321 deflections while using reduce, and reduces a turning point 320 of this driven inner peripheral surface 321 because of the tired chance of damaging, and the structural strength of this sleeve is stronger, comparatively durable.

Two, with this first blocking section 324, the second blocking section 325, to card section 411, keep out the blocking mode of end face 43, color and the lines of the complete maintainance set T-Ring outer peripheral face 4 of energy are complete, the color of this cover T-Ring 4 can be not identical with the color of accepting ring 3, make this sleeve produce two-color effect, or the surface of this cover T-Ring 4 produces lines, this sleeve is also added attractive in appearance.

Three, this cover T-Ring 4 can be made by more expensive and firmer metal, even if so accept ring 3, by not firmer and cheap material, is made, and still can reach good intensity, with endurance degree, reaches the beneficial effect of saving manufacturing cost.
