Abstract
The utility model discloses a rollback-preventing adjusting arm for precise adjustment, comprising a shell, a worm as well as a worm shaft and a gear connected with the worm. One end of the worm shaft is provided with a catch and an end socket while the other end of the warm shaft is provided with a lock positioning structure and a locking structure, wherein the locking structure is arranged on the outer side of the lock positioning structure. The rollback-preventing adjusting arm has the advantages of simple structure, low manufacturing cost, convenience in assembly and high quality, can greatly improve the adjusting precision of the worm shaft and prevents rollback.
Description
Technical field
The utility model relates to a kind of adjustment arm, especially relates to a kind of fine adjustment stopping adjustment arm.
Background technique
At present, the manual gap adjustment arm in the known brake system of car is made up of major parts such as shell, worm gear, worm screw and worm shafts, and the worm shaft degree of regulation is between 6 grades to 12 grades, and keying structure is lock tube, column cap and the interior form of ending.The worm shaft degree of regulation is not high, and lock tube keying structure sealing is not strong, the easy again rollback of column cap keying structure, and interior keying structure manufacture cost height and the quality instability of ending is unfavorable for long-run development.
By on can know that addressing these problems is extremely urgent!
In view of this, the inventor has done deep research to this, and by feat of the experience of being engaged in relevant industries for many years and practice; Design a kind of fine adjustment stopping adjustment arm; Exquisiteness simple in structure, manufacture cost is lower, and is in use easy to assembly and quality of product is high; Can increase substantially the degree of regulation of worm shaft and not have the rollback phenomenon and take place, this case produces thus.
The model utility content
There are the problems referred to above in the existing technology in order to overcome; The utility model provides a kind of fine adjustment stopping adjustment arm, exquisiteness simple in structure, and manufacture cost is lower; In use easy to assembly and quality of product is high, can increase substantially the degree of regulation of worm shaft and not have the rollback phenomenon and take place.
To achieve these goals, the technological scheme of the utility model is following:
Fine adjustment stopping adjustment arm; Comprise shell, worm screw, worm shaft that is connected with worm screw and gear is characterized in that: an end of said worm shaft is provided with catch and end socket; The other end is provided with locking position structure and locking structure, and said locking structure is arranged on the outside of locking position structure.
Further, said locking position structure comprises external gear and the internal gear that interconnects setting;
Further, said locking structure is a knurled nut;
Further, be provided with a stage clip between said locking position structure and the worm shaft;
The beneficial effect of the utility model is: the utility model is provided with catch and end socket at an end of worm shaft; The other end is provided with locking position structure and locking structure, and said locking structure is arranged on the outside of locking position structure, such structure setting; Can play fine adjustment; Wherein use internal gear and external gear to carry out the locking location, Location accuracy is 21 grades, and the knurled nut plays the effect of sealing and locking worm shaft.
By on can know, the utility model exquisiteness simple in structure, manufacture cost is lower, and is in use easy to assembly and quality of product is high, can increase substantially the degree of regulation of worm shaft and not have the rollback phenomenon to take place.
In order further to explain the technological scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
