Abstract

The utility model discloses a portable bolt driver for vehicle rims with larger torque, which is composed of a shell 1, a fixed ring 2, a driving shaft 3, a driving gear 4, a middle shaft 5, a middle gear 6, a main shaft 8, a main gear 9, a bolt sheathing head 10, a hand crank 11, etc. All the shafts and gears are installed in the shell by the axle holes of the shell, and the gears are engaged with one another successively. The driving shaft 3 is rotated by the hand crank 11 to drive the driving gear 4 and other gears, the rotary torque is transferred to a steel rim bolt 15 through the main shaft 8 and bolt sheathing head 10, and because the number of teeth of each pair of engaged gears is increased in multiples, the torque is magnified tens of times. The utility model is laborsaving and convenient to assemble and disassemble the bolts of steel rims.

Description

Manual type Automobile steel ring screw replacer

The utility model relates to a kind of portable service tools that is used for dismounting Automobile steel ring screw, especially can be used in the situation that needs twist moment bigger.

The Automobile steel ring screw dismantling devices that uses has multiple now: have electrically operated and replacer steam-operating at motor transport repair shop, drawing heavily with motor belt, wheel utilizes impact to carry out degree of tightness.The sleeve that has that carries with car adds the simple and easy replacer of lever.Because it is less that sleeve adds the moment of torsion of lever, at repair plant with steel ring screw electronic or that the steam-operating replacer is installed, often can't dismounting with sleeve and lever, cause difficulty to the chaufeur changing of tire.

The purpose of this utility model just provides a kind of can carrying with car, and manual type Automobile steel ring screw dismantling devices makes in the way changing of tire simple and easy to do.

The utility model be achieved in that the utility model by housing, mounting ring, imput shaft, driving gear, tween drive shaft, intermediate gear, main shaft, main gear, screw is pullover and hand crank etc. is formed, mounting ring is fixed on a side of housing, imput shaft, driving gear, tween drive shaft, intermediate gear, main shaft, main gear are installed in the housing by the axis hole of housing, and each gear meshes successively.

The utility model adopts above-mentioned structure to have following beneficial effect: when using the utility model, mounting ring is fixed in wheel hub, and a pullover end and the main shaft of screw joins, and the other end is placed in the screw that needs dismounting.Rotate imput shaft with hand crank, drive driving gear and each later gear rotation, moment of rotation is delivered to main shaft at last and screw is pullover, because the number of teeth of every pair of engaging gear is multiplied, moment of torsion can be exaggerated tens of times.Thereby, use manual type Automobile steel ring screw replacer can be laborsaving, dismounting steel ring screw easily.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a front elevation of the present utility model.

Fig. 2 is a lateral plan of the present utility model.

Fig. 3 is the I-I cutaway view of Fig. 1.

Fig. 4 is the I-I cutaway view of Fig. 3.

Fig. 5 is the II-II cutaway view of Fig. 3.

Fig. 6 is the III-III cutaway view of Fig. 3.

Among the figure, housing 1, mounting ring 2, imput shaft 3, driving gear 4, tween drive shaft 5, intermediate gear I6, intermediate gear II7, main shaft 8, main gear 9, screw is pullover 10, hand crank 11, wheel hub 12, check screw 13, tapped bore 14, steel ring screw 15, shifting block 16, driving lever 17, shift lever axis 18, allocating slot 19.

In Fig. 1, mounting ring 2 is fixed on a side of housing 1.

In Fig. 2, an end of imput shaft 3, tween drive shaft 5, main shaft 8 all is exposed to outside the housing 1 by the axis hole on the housing 1, all can join with hand crank 11, and the other end of main shaft 8 is exposed to the mounting ring side of housing 1, can join with screw pullover 10.

In Fig. 3, driving gear 4, intermediate gear I6, intermediate gear II7, main gear 9 are installed in the housing 1.Driving gear 4 and imput shaft 3 are fixing and all be fixed in tween drive shaft 5 and by its location, main gear 9 is by main shaft 8 location by its location, intermediate gear I6 and intermediate gear II7.The axis hole that main shaft 8 can prolong housing slides.Form basal part in main gear 9 centre portions thickenings, allocating slot 19 is arranged in the periphery of basal part.Pullover 10 1 ends of screw and main shaft 8 join, and the other end and steel ring screw 15 join.

In Fig. 4, main gear 9 numbers of teeth are greater than intermediate gear II7, and the two is meshed.The main gear hole is a polygon, is consistent with the profile of main shaft 8, and main gear 9 can prolong main shaft 8 and slide.

In Fig. 5, the number of teeth of intermediate gear I6 is greater than driving gear 4, and the two is meshed.Shift lever axis 18 is fixed in the inner face of housing 1, and driving lever 17 1 ends are exposed to outside the housing 1 by the aperture of housing 1, and the other end is divided into two, and its end is fixed with shifting block 17.Driving lever 17 is by shift lever axis 18 location.Two shifting blocks 16 are positioned at allocating slot 19, prolong main shaft 8 and slide thereby driving lever 17 can drive main gears 9 by shifting block 16, the engagement of control main gear 9 and intermediate gear II7 with separate.

In Fig. 6, check screw 13 is spun in the tapped bore 14 of mounting ring 2, and rotation check screw 13 can be fixed in wheel hub 12 with mounting ring 2.

During use, mounting ring 2 is placed in wheel hub 12, and an end and the main shaft 8 of screw pullover 10 join, and flexible main shaft 8 makes the other end of screw pullover 10 be placed in the screw 15 that needs dismounting, and the screw 13 that is tightened is fixed in wheel hub 13 with mounting ring 2.Stir driving lever 18, make main gear 9 and intermediate gear II7 engagement, with hand crank 11 rotation imput shaft 3, promptly dismantled and assembled Automobile steel ring screw 15.If screw 15 is pine, available hand crank 11 rotation tween drive shafts 5.If screw 15 is pine especially, directly use hand crank 11 live spindles 8, at this moment should stir driving lever 17 earlier, main gear 9 is separated with intermediate gear II7, other gears are stopped the rotation, lighten the load.
