Abstract
The utility model relates to a waterproof worm wheel head, including casing, worm wheel, worm, hand wheel and translucent cover, installation worm wheel and worm in the casing, worm are worn out the casing and at the outside of worm head installation hand wheel, adorn a connecting piece that has the stand admittedly at the top surface of worm wheel, and half spherical shell of coaxial suit on the stand of connecting piece scribbles the colour at the outer wall of hemisphere shell and indicates, a coaxial spiral -lock translucent cover outside the hemisphere shell, and the outer wall at the casing is fixed to this translucent cover. This worm wheel head can not intake through transparent buckler protection inner structure and instruction ball, is fit for the many environment of outdoor sleet and is fit for using in aqueous yet.
Description
Technical field
The utility model belongs to valve field, relates to worm wheel head, especially a kind of waterproof worm wheel head.
Background technique
Worm wheel head is the mechanism of control valve unlatching and rate-of flow, and the similar circle of shape of traditional worm wheel head housing connects inner worm gear at the outer side surface of housing and installs pointer, by the pointer display switch of valve and the degree of unlatching.Described pointer is many to be made by iron plate, and valve installation, in outdoor, runs into sleety weather unavoidably, and iron plate pointer is easily corroded, and particularly uses the valve in water, and this structure is more inapplicable.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of waterproof type worm wheel head, can be used in outdoor or under water.
The technological scheme that the utility model technical solution problem adopts is:
A kind of waterproof worm wheel head, comprise housing, worm gear, worm screw, handwheel and transparent cover, worm gear and worm screw are installed in housing, worm screw passes housing and installs handwheel at the outboard head portion of worm screw, be fixedly mounted with at the end face of worm gear the link that has column, coaxial package one hemispherical Shell on the column of link, scribble color instruction at the outer wall of hemispherical Shell, at outer coaxial spiral-lock one transparent cover of hemispherical Shell, this transparent cover is fixed on the outer wall of housing.
And described worm gear is made up of circumferential body and 1/3 bevel gear, be coaxially shaped with 1/3 bevel gear in the outer rim of circumferential body.
And described transparent cover is by the outer wall of bolt Corner Strapped at housing.
Advantage of the present utility model and good effect are:
1, this worm wheel head can not be intake by transparent watertight cover protection internal structure and instruction ball, and the environment being applicable to outdoor sleet many is also adapted at using in water.
2, the hemispherical Shell that this worm wheel head indicates with color is fixed on worm gear by a connection piece, and the direction of worm gear wheel and degree can be judged by color instruction, and smart structural design is reasonable.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model;
Fig. 3 is that the A-A of Fig. 1 is to cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of waterproof worm wheel head, comprise housing 2, worm gear 4, worm screw 5, handwheel 1 and transparent cover 3, worm gear and worm screw are installed in housing, worm screw passes housing and installs handwheel at the outboard head portion of worm screw, be fixedly mounted with at the end face of worm gear the link 7 that has column, coaxial package one hemispherical Shell 6 on the column of link, scribble color instruction at the outer wall of hemispherical Shell, at outer coaxial spiral-lock one transparent cover of hemispherical Shell, this transparent cover is by the outer wall of bolt Corner Strapped at housing.
Described worm gear is made up of circumferential body and 1/3 bevel gear, and be coaxially shaped with 1/3 bevel gear in the outer rim of circumferential body, the spire of 1/3 bevel gear and worm screw is connected with a joggle.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from model utility design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
