The utility model has solved again can't be dismantled after the existing in prior technology assembling is finished, and can only take destructive means in case break down, and causes the part component to scrap, and increases user cost, can't reuse the technical problem of less economical grade; A kind of dismounting of being convenient to is provided, can have reused, arm is adjusted in the self locking type brake that user cost is cheap.
The utility model has also solved existing in prior technology and has been difficult to assembling and debugging, reject rate height, the technical problem of the not satisfactory grade of sealing; A kind of be convenient to assembling and debugging are provided, and reject rate is low, and arm is adjusted in the detachable brake of good airproof performance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: arm is adjusted in the self locking type brake, comprise housing, be located at worm gear, worm mechanism in it, on housing, be provided with the adjustment axis hole, it is matched with worm screw by adjusting axle to adjust axis hole, it is characterized in that evenly being furnished with some shrinkage pools on described adjustment axle, its periphery is provided with the gear ring that is coupled on the housing, is provided with a steel ball that adapts with shrinkage pool in the described gear ring at least; The described root of adjusting axle is provided with circular groove, and described housing is provided with the guide wheel hole, and described guide wheel is provided with the guide wheel that matches with circular groove in the hole.The utility model is convenient to assembling, and processing and fabricating is convenient, effectively prevents the stuck problem of worm and gear in assembly process.
As preferably, described adjustment axis hole is a through hole, and described adjustment axle is arranged in to be adjusted in the axis hole; Be provided with lid in the bottom of adjusting axis hole.Adjustment axle of the present utility model is after assembling is finished, in case find that assembling occurs that deviation effects is normally used or when the stuck situation of worm and gear occurring, can will adjust axle from the lower ending opening of adjusting axis hole with instrument ejects, thereby assemble again, realized the repeated use of product, and can not produce the situation of scrapping, effectively reduce user cost.
Owing to will adjust axis hole and be made as through hole, its two ends all are easy to generate the space like this, and in order to improve sealability, as preferably, the top of described adjustment axis hole is provided with oil sealing; The bottom of described adjustment axis hole is provided with step, is provided with oil sealing down on step.
As preferably, described adjustment axle is made as single opposite side or many opposite side shape for matched section with worm screw, and the matching hole of associated worm screw also is made as single opposite side or many opposite side shape.
As preferably, be Spielpassung between described adjustment axle and the worm screw, be Spielpassung between described circular groove and guide wheel and guide wheel hole and the guide wheel.Adopt Spielpassung to avoid because of worm screw and adjusted between the axle causing the stuck problem of worm and gear because of guidance quality difference.
Stressed even in order to make, as preferably, evenly be provided with several tooth mouths on the described gear ring, be provided with a pair of steel ball that adapts with the shrinkage pool of adjusting on the axle in it symmetrically.
As preferably, an end of described housing is provided with lining, and pressing plate is matched by gasket seal and locating piece and housing; And on housing, be provided with pump nozzle.
Therefore, the utlity model has following advantage: 1, reasonable in design, simple in structure, effect is remarkable; 2, be convenient to assembling, processing and fabricating is convenient, prevents that effectively the self locking type brake of the stuck problem of worm and gear in assembly process from adjusting arm; 3, in case find that assembling occurs that deviation effects is normally used or when the stuck situation of worm and gear occurring, can will adjust axle from the lower ending opening of adjusting axis hole with instrument ejects, thereby assemble again, realized the repeated use of product, and can not produce the situation of scrapping, effectively reduce user cost.
