Abstract
The utility model relates to a boosting socket wrench, comprising an involute gear planetary mechanism which is arranged between a ratchet wrench and a socket head. When a sun wheel axle drives and a planetary frame axle is driven, speed can be reduced and a force moment can be increased, so that a nut can be loosened or fixedly screwed with labour saving; on the contrary, when the planetary frame axle drives and the sun wheel axle is driven, the speed can be increased and the force moment can be decreased, so that the nut can be screwed in or dismounted rapidly. The utility model has the advantages of small structure, convenient operation, labor saving and time saving in using.
Description
The utility model relates to a kind of reinforcement box spanner, and it is the necessary instrument of loading and unloading nut (bolt).
Existing spanner is of a great variety, as solid wrench and monkey wrench or the like, uses very extensive.But they all are directly to drive with hand-power, and are middle without any speed change, thereby it is not enough or rotation is too slow just to show moment in some occasion, can not satisfy user's requirement.Society now particularly, cars ' entry into family, life joint gather quickenings, and the utmost point needs a kind of light and handy labour-saving spanner, to be fit to all motorists' uses.
The utility model purpose just provides a kind of light laborsaving timesaving reinforcement box spanner, and it is laborsaving to seem when it makes fastening nut, and becomes quick when moving back removing nut.
Technical solution of the present utility model is, a kind of reinforcement box spanner, and it is by the involute gear planetary mechanism, the first-class composition of ratchet spanner and sleeve.When ratchet spanner is contained on the sun wheel shaft, and collet head is when being contained on the planet carrier axle, and the big big retarding of transmission makes and tightens or the turn nut becomes laborsaving; On the contrary, when ratchet spanner is contained on the planet carrier axle, and collet head is when being contained in sun wheel shaft, and transmission is then quickened widely, makes to move back removing nut and become soon just.
Below in conjunction with embodiment shown in the drawings, the utility model will be further described.
Accompanying drawing is the whole cutaway view of present embodiment.
The utility model is made up of sun wheel shaft (2), internal gear (5), planetary gear (6), planet carrier axle (8) and ratchet spanner (1) and collet head (9) etc.Sun wheel shaft (2) and planet carrier axle (8) are located in housing (7) by bearing (3) respectively.Housing (7) utilizes screw thread to connect with the internal gear with eccentric structure (5).Planet carrier axle (8) is gone up uniform three planetary gears (6).They all cog with sun wheel shaft (2) and internal gear (5) is meshed.On internal gear (5) outer rim steady arm (4) is housed, and sun wheel shaft (2) end and planet carrier axle (8) end can be installed ratchet spanner (1) or collet head (9) on demand respectively.During use, halt in a certain position by steady arm (4).When ratchet spanner (1) is enclosed within on the sun wheel shaft (2), collet head (9) is enclosed within on the planet carrier axle (8), be that sun wheel shaft (2) is active, planet carrier axle (8) is driven, its gearratio i=n sun wheel shaft/n planet wheel spindle＞＞1, this moment, rotating speed was by high step-down, and turning moment increases, and is applicable to begin the loosening or last solid nut of twisting; On the contrary, if ratchet spanner (1) is contained on the planet carrier axle (8), and collet head (9) is contained on the sun wheel shaft (2), planet carrier axle this moment (8) is initiatively, and sun wheel shaft (2) is driven, this i=n planet wheel spindle/n sun wheel shaft＜＜1 of its transmission, rotating speed is uprised by low, turning moment reduces, and this is used for screwing fast before the withdrawing from fast or tightening behind the loose nut, thereby has improved effect.
The utility model volume is little, and is in light weight, easy to operate, the work flexibility and reliability, and range of application is wide.
Claims (3)
1, a kind of reinforcement box spanner, it is by transmission mechanism, and the first-class composition of ratchet spanner and sleeve is characterized in that driving section employing involute gear planetary mechanism, comprises sun wheel shaft (2), internal gear (5), planetary gear (6) and planet carrier axle (8) etc.
2, reinforcement box spanner according to claim 1 is characterized in that planet carrier axle (8) is provided with three uniform little axles, moving three planetary gears (6) of joining on it.
3, reinforcement box spanner according to claim 1 is characterized in that having on the internal gear (5) of eccentric excircle steady arm (4) is housed.
