Description

Four-head is manually torn the wheel instrument open

The utility model relates to a kind of four-head and manually tears the wheel instrument open.

Automotive wheel generally is by four nuts or the nut more than four wheel to be fixed tightly on the axletree, tightens or unclamps a nut, according to varying in size of car, if with spanner dismounting nut, need very big power, and at every turn can only dismounting one, generally need the power more than tens kilograms at least.

In Chinese patent application number is to disclose name in 91228169.3 to be called " tube lifter ", and its structure includes a body, protecgulum, bonnet, first driver element, second driver element, transmission component and align member.During use, earlier the collet head on second driver element is sheathed on wheel and goes up on the nut of desire dismounting, to make align member withstand between body and the ground, the application of force makes the rotation of first driver element then, drive the rotation of second driver element by transmission component, the nut on the wheel can be unscrewed.In case after the nut that the user will take turns unscrews, will take turns dismantling devices and be reversed end for end, sleeve is changed be placed on first socket part, and rocking bar is installed on second socket part, can apace all nuts be screwed off.The tube lifter of this structure is because for preventing the body rotation, on body, be provided with a location member, nut of every dismounting is all different according to the seat height of nut on wheel, from newly controlling align member, or the length of regulating align member, the ground soft or hard that adds upper support differs, and is uneven, the adjusting of align member is comparatively frequent, uses to seem inconvenient.Moreover, though nut unscrew, if nut or screw rod any one get rusty or between foreign material such as silt are arranged, all can cause getting loose of nut freely not suitable; Will not take turns dismantling devices and turn and just the nut that gets loose can be screwed off, and can only revolve next nut at every turn, still quick inadequately.

In Chinese patent application number is to disclose name in 85202707 to be called " simple and easy wheel nut loader ", its structure includes a motor, big small belt pulley, be connected in the cone belt on the big small belt pulley, main shaft and on the lug nut cover, bearing, striking arm circle cover impulse pin etc., when motor rotates, drive the deceleration belt pulley, make the impulse pin that is fixed on the big belt pulley make circular movement together, after the impulse pin seat moves to and is with striking arm circle cover part to collide, the rotation of big belt pulley is by the effect of impulse pin at this moment, drive striking arm circle cover and main shaft and rotate together, make main shaft and wheel ut socket obtain moment of torsion strength, wheel is torn or pretend open industry.This kind removing machine is owing to adopt pulley transmission structure, this heaviness very, and also bulky, be not easy to operation.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, provide a compact conformation, simply light and handy, easy to use, dismounting efficiently four-head manually tear the wheel instrument open.

For realizing the purpose of this utility model, this four-head is manually torn the wheel instrument open, include a housing, actuator, the drive division of housing be provided with automotive wheels on cooresponding several rotating shafts of clamp nut, in each rotating shaft, be provided with connect with sleeve pullover, one cover transmission component is arranged, be connected between each rotating shaft and the actuator.

Fig. 1 manually tears the constructional drawing of wheel instrument open for the utility model four-head.

Fig. 2 is the A-A cutaway view among Fig. 1.

Fig. 3 is the constructional drawing that retarder connects with actuator.

Fig. 4 is the B-B cutaway view among Fig. 3.

Below in conjunction with accompanying drawing, the utility model four-head is manually torn open one of them embodiment of wheel instrument is described in further detail:

As shown in Fig. 1 and Fig. 2, the utility model four-head is manually torn the wheel instrument open, includes a housing (1), actuator (2), is provided with square or hexagonal cylinder (12) on actuator (2), is convenient to spanner or sleeve is pulled.The drive division (4) of levying housing (1) is provided with four rotating shafts (5), and it is corresponding that its setting is that the automotive wheels with four nuts tightens the position of nut.Can certainly be arranged to and five, six or to tighten the position of nut with the automotive wheels of last nut corresponding.In each rotating shaft (5), be provided with pullover (6) that connect with sleeve.During operation, can jacket casing with different size on, once with the nut all equilibrium dismounting on the automotive wheels.And transmission component (7) comprises retarder (8) that is arranged in housing (1) Handheld Division (3) and the driver (10) that is arranged in housing (1) drive division (4), described driver (10) comprises again and the fastening driven gears that connect of four rotating shafts (5) (11), the center shaft (13) that is enclosed within drive division (4) go up and with driven gear (11) and with retarder (8) output gear (14) ingear center dual gear (13).Driver (10) also can be to comprise and the fastening driven gear that connects of rotating shaft (5) (11), output gear (14) on described driven gear (11) and the retarder (8) directly meshes, in the middle of just the output gear (14) on the retarder (8) being arranged on, each rotating shaft (5) and actuator (2) are linked together.The power more suffered than nut of a dismounting owing to four nuts of a dismounting is big four times, adopt dual gear like this, not only play driving action, and can further regulate rotating speed again, be convenient to setting and the adjustment of actuator on positional structure, also alleviate the power that applies on the actuator simultaneously, make to produce to refer to make four-head manually to tear the wheel instrument open more flexible.

As shown in Fig. 3 and Fig. 4, described retarder (8) comprises the rotating disk (15) that has output gear (14), is provided with three jack-posts (16) on rotating disk (15), and correspondence is with can be around three planetary wheels (17) of jack-post (16) rotation.Described rotating disk (15) is two, also can several be set according to circumstances, and corresponding jack-post (16) and planetary wheel (17) also dispose two cover or some covers.In retarder (8) gear case (19), be provided with planetary wheel (17) ingear inner gear (20), have on the actuator (2) one with planetary wheel (17) ingear driven wheel (18).Be provided with wear-resisting copper sheathing (21) between output gear (14) and the gear case (19), actuator (2) can be gone up at the case lid (22) of gear case (19) and rotate.Such structure design makes retarder be arranged on the Handheld Division, can make the outside maintenance in Handheld Division cylindric, be convenient to hand and arrest operation, and compact conformation, light and handy.

The utility model four-head hand wheel removing tool is than prior art and since adopted with automotive wheels on clamp nut pair Four rotating shafts of answering and pullover and bull drive the deceleration assembly and are connected in structure between four rotating shafts and the driver, at the dismounting spiral shell When female, can utilize the relative fixed position of automotive wheels top nut to fix the four-head hand wheel removing tool, avoid because of the turn nut The time the own rotation of four-head hand wheel removing tool that produces, and the Handheld Division is fit to the operation of hand, have use light and handy, convenient, Simple in structure, compact, dismounting is advantage efficiently.
