Description
Technical field
The utility model relates to a kind of lock clutch.
Background technology
At present, general door lock all is provided with the clutch that cooperates with door handle, as Chinese patent application number 01227336.6, the day for announcing is on May 1st, 2002, name is called the patent of " clutch of lock ", the clutch that this application case discloses a kind of lock comprises front axle and rear axle, and rear axle housing also comprises playing post, spring and fore-set on front axle but both separation can not interlock; Front axle is provided with a front axle aperture, plays the post activity and is contained in the front axle aperture, between the bottom of bullet post and front axle aperture spring is housed; Position corresponding to the front axle aperture on the rear axle is provided with a rear axle aperture, being contained in the rear axle aperture of fore-set activity.Utilize the front axle post of being hit by a bullet to insert or do not insert in the rear axle, realize the interlock of front axle and rear axle or interlock not, thus realized lock close and from operation.There is following defective in this clutch: because the rear axle aperture on the rear axle is aperture, a front and back unanimity, fore-set very easily therefrom drops out.At this technological deficiency, someone changes the rear axle aperture on the rear axle into through hole that the rear axle outer wall of " U " shape groove and " U " shape slot tail correspondence is provided with, fore-set is "T"-shaped or the middle part is provided with boss, be that fore-set can slidably reciprocate in " U " shape groove, its projection may be stuck in the above-mentioned through hole to prevent that fore-set from dropping out simultaneously.The defective of this technical scheme is: during the clutch running, the fore-set top in " U " row groove is open, causes fore-set the oblique top phenomenon to occur easily, makes the clutch afunction, and promptly the lock handle hand dallies all the time.
The utility model content
At the prior art deficiency, the lock clutch of above-mentioned oblique top phenomenon appears in a kind of clutch that effectively prevents of the special proposition of the utility model.
For achieving the above object, the utility model is taked following technical scheme:
Lock clutch comprises clutch outer ring 1, clutch inner ring 2 and on-of pin elastic parts, and described clutch inner ring 2 inserts in the centre bore 13 of described clutch outer ring 1 slidably; Described clutch outer ring 1 radially is provided with " U " shape groove 11 and the clutch cycle hole 12 coaxial with described " U " shape groove 11, the clutch inner ring hole 21 that the radially setting of described clutch inner ring 2 and described clutch cycle hole 12 are coaxial; Described on-of pin elastic parts comprises clutch pad 3, clutch set bar 4 and clutch interlock spring 5, and is arranged in the passage of " U " shape groove 11, clutch cycle hole 12 and clutch inner ring hole 21 formations; Top in described clutch outer ring 1 is provided with annulus frame 61, the radial finger of described annulus frame 61 is provided with the on-of pin limited block 6 suitable with described " U " shape groove 11 to center of circle direction, and described on-of pin limited block 6 covers on the described clutch pad 3 that is positioned at described " U " shape groove 11.
Described on-of pin limited block 6 and annulus frame 61 can be an overall structure, also can be fixed together by other connected modes.The top of described clutch outer ring 1 is " U " shape groove 11 opening directions ends pointed.When described annulus frame 61 is placed on 1 top, described clutch outer ring, described on-of pin limited block 6 is positioned in described " U " shape groove 11.When the external force of the described clutch pad 3 of compressing disappears, when the radially clutch inner ring hole 21 that clutch inner ring 2 relative clutch outer rings 1 rotate to clutch inner ring 2 and radially " U " shape groove 11 of clutch outer ring 1 and clutch cycle hole 12 are in same radial position, under the elastic force effect of clutch interlock spring 5, clutch set bar 4 is sprung in radially " U " shape groove 11 of clutch outer ring 1, and withstand the afterbody of clutch pad 3, the front portion that makes clutch pad 3 eject clutch cycle hole 12 and the afterbody screens in " U " shape groove 11.The bottom surface of described on-of pin limited block 6 is positioned at the top of clutch pad 3 and clutch set bar 4, remedied the open room that is in clutch pad 3 tops in " U " shape groove, make its cooperate with " U " shape groove 11 form one make just clutch pad 3 and clutch set bar 4 can be smoothly at the passage of interior slip, thereby can prevent that the oblique top phenomenon from appearring in clutch pad 3.
The utility model can also be, described clutch inner ring 2 tops are provided with the chimb 22 that is flange-like, and described chimb 22 is pressed in the upper surface of described on-of pin limited block 6.Described clutch inner ring chimb 22 can just in time make clutch inner ring 2 be overlapped on the clutch outer ring 1, not influencing the counterrotating while between clutch inner ring 2 and the clutch outer ring 1, can play mutual positioning action between the two.Simultaneously be pressed on the described on-of pin limited block 6 also can be to on-of pin limited block 6 location for described clutch inner ring chimb 22, when preventing that oblique top trend from appearring in clutch pad 3 with on-of pin limited block 6 jack-up.
The utility model can also be, the top of described clutch outer ring 1 is provided with pit 14, and described annulus frame 61 is arranged in the pit 14 movably; The external diameter of described chimb 22 is less than the internal diameter of described annulus frame 61, and described annulus frame 61 is arranged between the sidewall 141 of described chimb 22 and described pit 14.Make that the assembling between described annulus frame 61 and clutch outer ring 1, the clutch inner ring 2 is more convenient, the permanent position of described annulus frame 61 is relatively stable, and then the limit effect of 6 pairs of clutch pads 3 of described on-of pin limited block is better.
The utility model can also be that described on-of pin limited block 6 is made for plastics.Described annulus frame 61 can create an overall structure with described on-of pin limited block 6 usefulness plastics, makes that its processing technology is simple, cost reduces.When described on-of pin limited block 6 just in time is clipped between the sidewall 141 of described chimb 22 and pit 14, can between the three, play the buffering lubrication simultaneously by the characteristic of the material of plastics own.
Compared with prior art, the beneficial effects of the utility model are:
1, since adopted on-of pin limited block 6 cooperate with " U " shape groove 11 one of formation make just clutch pad 3 and clutch set bar 4 can be smoothly at the passage of interior slip, remedied the open room that is in clutch pad 3 tops in " U " shape groove, thereby can prevent that the oblique top phenomenon from appearring in clutch pad 3, make clutch work more stable.
2, owing to be connected an annulus frame 61 on described on-of pin limited block 6, described annulus frame 61 is arranged on 1 top, described clutch outer ring, on-of pin limited block 6 conveniently is positioned in " U " shape groove 11, and makes things convenient for its installation.
3, because the top of clutch inner ring 2 outer walls is provided with clutch inner ring chimb 22, not only can make between clutch inner ring 2 and the clutch outer ring 1 and locate mutually, and described clutch inner ring chimb 22 be pressed in described on-of pin limited block 6 upper surfaces also can be to on-of pin limited block 6 location, when preventing that oblique top from appearring in clutch pad 3 with on-of pin limited block 6 jack-up, make on-of pin limited block 6 functions more stable, and then make clutch work more stable.
4, since described annulus frame 61 be arranged on movably in the pit 14 on top of described clutch outer ring 1, the external diameter of described chimb 22 is less than the internal diameter of described annulus frame 61, described annulus frame 61 is arranged between the sidewall 141 of described chimb 22 and described pit 14, in the process of assembling clutch, assembling between described annulus frame 61 and clutch outer ring 1, the clutch inner ring 2 is more convenient, the permanent position of described annulus frame 61 is relatively stable, and then the limit effect of 6 pairs of clutch pads 3 of described on-of pin limited block is better.
Owing to the utlity model has above-mentioned advantage, so can be widely used in all kinds of locks that need clutch.
