Description

A kind of self-locking joint structure of angle adjustable

Technical field

This utility model belongs to mechanical structure field, is related to a kind of self-locking joint structure of angle adjustable.

Background technology

With the development in epoch, the continuous progress of mechanical automation integral level, in actual production, people are for machinery The switching performance of joint requires more and more higher, not only requires nothing more than firm and reliable connection, in addition it is also necessary to which local detail has abundant Controllability.The connection of mechanical joint on the market at present mostly is dead and connects, even angle adjustable is also to complete in regulation It is fixed dead afterwards.

The above-mentioned prior art for referring to of analysis has the following disadvantages, i.e. technical problem to be solved in the utility model:

（1）Mechanical joint is dead connection, and after the completion of fixing, angle is unadjustable, for some need to do joint angles adjustment Product, dead link mechanical joint just do not apply to；

（2）The joint of adjustable-angle, must be dead by arthrodesis after the completion of regulation in order to ensure coupling stiffness, if Need again first to unclamp joint locking when needing to adjust again angle, it is fixed dead again after the completion of regulation, leverage work effect Rate.

Utility model content

The purpose of this utility model is to overcome defect present in existing structure, designs a kind of self lock of angle adjustable Nodule structure.The structure is mainly used in mechanical structure field.Efficiently solve existing structure angle non-adjustable, adjust efficiency low Shortcoming.

To achieve these goals, the technical solution of the utility model is to design a kind of self lock nodule of angle adjustable Structure, including lower cover（101）, spring（102）, button（103）, tack jackscrew（104）, upper lid（105）, screens axle（106）.

Wherein, the lower cover（101）On have square hole, screwed hole, totally 2；The spring（102）For tower spring, totally 2；Institute State button（103）One end has angle to be oriented to, and mid portion has external gear teeth, and there is square shaft one end, and top is provided with notch, has 2；The tack jackscrew（104）For standard component, totally 8；The upper lid（105）There is angle on axis, have 2；The card Position axle（106）While there is internal tooth wheel bore, gear bore edges have equally distributed screwed hole, have 2.

Its annexation is：By described spring（102）It is set to button（103）Square shaft on, button（103）Side Shape axle again with lower cover（101）Square opening matching, with described tack jackscrew（104）Do spacing connection, described screens axle （106）It is pressed onto lower cover（101）On end face, screens axle（106）Internal tooth wheel bore and button（103）External gear teeth coordinate, it is described Upper lid（105）It is pressed onto screens axle（106）On, upper lid（105）On angle and button（103）Angle is matched.

Advantage of the present utility model and beneficial effect are：This utility model adopts button control joint opening-closing locking, Spring in the raw when, screens axle internal gear is engaged with button external gear, and joint is in locked position, it is impossible to it is mobile or Rotate, you can transmission power or moment of torsion.Press the button, spring-compressed, screens axle internal gear is departed from button external gear, now Joint is in folding condition, and now joint can rotate regulation angle, adjusts release button after angle, and screens axle is with button again Occlusion, joint locking.Needs are specialized, because button is engaged for gear with screens axle, the angle for turning over and tooth Number is related.This utility model is melted into joint self-locking and angular adjustment in one structure, and overall structure is simply clean and tidy, simple to operate Efficiency high.
