Description
Technical field
The utility model belongs to the sanitary bath equipment field, especially relates to a kind of handwheel fixing device of sanitary bath equipment.
Technical background
The handwheel operating mechanism is more common on sanitary bath equipment, it is to drive rotating shaft by handwheel to rotate in a circumferential direction and complete operation or control, existing common sanitary bath equipment handwheel is fixedly connected to be such: after the axial bore at handwheel center is passed in rotating shaft, again by being threaded in nut or screw and the rotating shaft, handwheel is compressed in rotating shaft, realize handwheel fixing in rotating shaft.
The deficiency of this fixedly connected mode is:
1, installing/dismounting inconvenience because the fixedly connected of handwheel is to realize by nut, the installing/dismounting handwheel, need take off nut earlier, the installing/dismounting inconvenience.
2, rotating shaft is passed behind the handwheel fixedly connectedly by nut, outside the end of rotating shaft and nut all are exposed to, influences attractive in appearance;
3, uncomfortable to the operation of handwheel, when operation, hand channel is often to the handwheel grasping, and handwheel has been showed nut and rotating shaft outward, and is uncomfortable during operation;
4, handwheel fixedly is to realize by nut in rotating shaft, and rotating shaft is matching relationship decision between armrest wheel and the rotating shaft with respect to the axial position of handwheel, and then to the higher requirement of machining accuracy proposition of handwheel and rotating shaft, manufacturability is poor.
Summary of the invention
The purpose of this utility model, be to have designed at the deficiency of prior art a kind ofly install and remove conveniently, attractive in appearance, operation is comfortable, the sanitary bath equipment handwheel fixing device of good manufacturability.
The utility model is to realize by such scheme:
A kind of handwheel fixing device, comprise handwheel seat, rotating shaft, handwheel, a circumferential limit stoper is set between handwheel and the rotating shaft, circumferentially limit stoper is circumferentially spacing with respect to rotating shaft with handwheel, on handwheel, be provided with the handwheel groove with the fitting surface of handwheel seat, the handwheel seat is provided with the handwheel seat groove corresponding with the handwheel groove, puts into elastic ring in handwheel groove and the formed groove of handwheel seat groove.
Circumferentially the effect of limit stoper is to make not produce circumferential relative movement between handwheel and the rotating shaft, and handwheel rotates in a circumferential direction and drives rotating shaft and rotate in a circumferential direction, to realize the manipulation of handwheel to institute's control mechanism.
Circumferentially limit stoper can adopt and be located at corresponding axial raised line and groove between rotating shaft and the handwheel, and its further optimal design is that raised line and groove are made as many, promptly forms the spline structure that cooperatively interacts, and is circumferentially spacing with respect to rotating shaft to realize handwheel.
Circumferentially limit stoper can also be handwheel with rotating shaft between the surface of contact that matches, the cross section of handwheel and rotating shaft fitting surface adopts noncircular cross section, as triangular-section, square cross section, hexagonal cross-section, realize rotating shaft circumferentially spacing with respect to handwheel by the surface of contact of handwheel and rotating shaft.
Circumferentially limit stoper can also adopt other structure, as long as can make handwheel not produce circumferential relative movement with respect to rotating shaft, and handwheel can move axially and gets final product.
Be easy-to-operat, handwheel is provided with at least one driving lever, and the design of optimizing is that driving lever is a plurality of, circumferentially is distributed on the handwheel.
Linkage structure between handwheel and the handwheel seat can be: have axle journal on the described handwheel, described handwheel seat center is provided with a hole, axle journal passes a hole, and described handwheel groove is arranged on the outer peripheral surface of axle journal, and described handwheel seat groove is arranged on the inner peripheral surface in a hole.
Linkage structure between handwheel and the handwheel seat also can be: described handwheel sleeve is in handwheel seat outside, the inner peripheral surface of described handwheel is corresponding with the outer peripheral surface of handwheel seat, described handwheel groove is arranged at the inner peripheral surface of handwheel, and described handwheel seat groove is arranged at the outer peripheral surface of handwheel seat.
It should be noted that simultaneously: the raised line of corresponding setting and groove, the axial surface of contact that matches, the lateral pin that matches and axial structures such as breach on rotating shaft and the axial bore can guarantee that all rotating shaft can moving axially with respect to axial bore.
Handwheel can move axially with respect to rotating shaft, wants to take off handwheel, directly handwheel is drawn vertically outwardly, and elastic ring produces distortion and breaks away from handwheel seat groove or handwheel groove, and handwheel can be pulled out; Want to install handwheel, handwheel is pressed vertically inwardly, elastic ring enters in handwheel seat groove and the formed groove of handwheel groove and gets final product.This shows that in the utility model, the installing/dismounting of handwheel is very convenient.
Owing to saved the structures such as nut of in the prior art structure handwheel being fixed, rotating shaft is hidden in the handwheel seat, and is very attractive in appearance.
Handwheel no longer exposes outward nut and rotating shaft, and operation comfort also is improved.
Because handwheel is to be connected and fixed by right-hand side wheel seat groove, handwheel groove, elastic ring and rotating shaft, handwheel and rotating shaft axial cooperated less demanding, technology capability is good.And if be equipped with axial clearance in the fixed connection place of handwheel seat, then handwheel and handwheel seat can be used as an integral body and move axially, and have kept the overall appearance form of handwheel and handwheel seat constant, have improved aesthetic property greatly.
In brief, comfortable, the good manufacturability of handwheel easy installation and removal, overall appearance, operation in the utility model.
