Description
Technical field
The present invention relates to a kind of ruggedness that can ensure that female seat and suite of tools, and the rotation action of the external member smooth-going that can make tool, to promote stopper torsion and to turn to the universal joints structure of smooth degree.
Background technology
Press, in order to use in the operation instrument (as first-class in sleeve, bottle opener) of the different different kenels of occasions collocation in response to the instrument of driving (such as pneumatic tool, Wrench, Screwdriver handle etc.), instrument adaptor is i.e. widely used, in order to make instrument adaptor can broader applications in the most easy-operating space, instrument adaptor i.e. has the design of universal adjustment.
Referring to shown in Fig. 1, be existing universal joint, it consists predominantly of female seat 10, suite of tools 11, latch 12 and the collar 13；The lower end of this female seat 10 is provided with the fit portion 101 being available for being socketed driving instrument, and upper end is provided with holding part 102, is equiped with spring 103, and offers relative and through two perforation 104 to this holding part 102 in outside in this holding part 102；nullOne end of this suite of tools 11 is provided with the bulb 111 in the holding part 102 that can insert female seat 10，The other end is provided with the drive division 112 being available for being socketed sleeve barrel tool，This bulb 111 another offer at two perforation 103 of corresponding female seat 10 outer imperial palace little wear groove 113，And with a latch 12 stretch through female seat 10 two perforation 104 and suite of tools 11 wear groove 113，And make the bulb 111 of suite of tools 11 be limited in the holding part 102 of female seat 10，The bulb 111 of this suite of tools 11 can pivot along latch 12，Make suite of tools 11 can carry out rotation in first direction，Suite of tools 11 wear the rotation space that groove 113 then provides bulb 111 to pivot in second direction along latch 12，The bulb 111 making suite of tools 11 can carry out rotation in second direction，And by this bulb 111 in first、The rotation in two directions compensates，Make suite of tools 11 can make universal go to action；Separately it is nested with retaining collar 13 again in the outside of female seat 10, for fastening screw 12；And in time carrying out dismounting operation, this suite of tools 11 is to utilize bulb 111 to be installed in the holding part 102 of female seat 10, though it makes female seat 10 and suite of tools 11 can smooth out go to action, but, when this female seat 10 rotates by this latch 12 clip driving tools external member 11, owing to being applied concurrently to latch 12 2 end when the stopper torsion of female seat 10, easily cause this latch 12 fracture damage, and then reduce the stopper torsion of universal joint.
nullRefer to Fig. 2、Fig. 3、Shown in Fig. 4，It is the M357344 two-period form tool-joint Patent Case of TaiWan, China bulletin，This tool-joint 20 includes operation 21、Support bar 22 and position limiting structure，One end of this operation 21 can connect driving instrument，The other end is provided with storage tank 211，And the flange 212 of a plurality of tool convex arc contact surface it is provided with at the sidewall of this storage tank 211，One end of this support bar 22 is provided with the polygonal ballhead 221 in the storage tank 211 that can insert operation 21，This polygonal ballhead 221 has a plurality of sides that convex arc contact surface with each flange 212 of this storage tank 211 respectively contacts，The other end of this support bar 22 is provided with the drive division 222 for being socketed other instrument，Separately being provided with one in the storage tank 211 of this operation 21 can be the position limiting structure of c-type button 23，Polygonal ballhead 221 with this support bar 22 spacing，And in time carrying out dismounting operation，It is the polygonal ballhead 221 of convex arc this support bar 22 of contact surface clip of each flange 212 with this operation 21，And clip transmission support bar 22 rotates，And the polygonal ballhead 221 of available this support bar 22 makees universal go to action for centring point，To carry out dismounting operation；But, this tool-joint 20 still has a following scarce fraud on using:
This operation 21 is the polygonal ballhead 221 utilizing each flange 212 clip support bar 22, rotate with clip transmission support bar 22, the restriction of each side of polygonal ballhead 221 of bar 22 it is supported due to the protrusion thickness system of each flange 212 of this operation 21, the each flange 212 making this operation 21 is only capable of the mutual clip of polygonal ballhead 221 of the protrusion thickness T with small and this support bar 22, it not only reduces the torque value of stopper, and after using a period of time, the polygonal ballhead 221 of this support bar 22 easily makes each flange 212 of this operation 21 produce and scrapes the situation damaging sphering, and make each flange 212 of this operation 21 cannot the polygonal ballhead 221 of clip transmission support bar 22, and then reduce service life.
The convex arc contact surface system of each flange 212 of this operation 21 is contacted with each side of polygonal ballhead 221 of this support bar 22, therefore, when operation 21 and support bar 22 go to action, the convex arc contact surface of each flange 212 of this operation 21 by directly with polygonal ballhead 221 each side phase mutual friction of this support bar 22, and make operation 21 and the support bar 22 cannot go to action smoothly.
In view of this, the present inventor satisfies the research and development being engaged in relevant industries with it for many years and making experience, further investigate for current problem encountered, through long-term endeavour research with study, eventually grind and create a kind of universal joints structure, to be effectively improved the shortcoming of background technology, this is the design aim of the present invention.
