Description

A kind of New type finger worm wheel head

Technical field

The utility model belongs to valve field, is related to worm wheel head, especially a kind of New type finger worm wheel head.

Background technique

Worm wheel head is that control valve is opened and the mechanism of rate-of flow, traditional worm wheel head indicator and worm gear casing are installed It is cumbersome, and worm gear casing is complex on processing and fabricating, manufacturing expense is higher.

Utility model content

The purpose of the utility model is to overcome in place of the deficiencies in the prior art, a kind of New type finger worm wheel head is provided, it can It is easy to operate to assemble worm gear casing and needle indicator in a short time, and can be mass when manufacture, reduce manufacture Cost.

The utility model technical scheme applied to solve the technical problem is:

A kind of New type finger worm wheel head, including shell, cap, worm gear and worm screw, worm gear and worm screw engagement connect in shell It connects, the worm screw outside shell is fixedly mounted with handwheel, and worm gear is pierced by from cap, the top surface of worm gear and cap either flush, in worm gear Top surface is coaxially fixedly mounted with a chassis, is coaxially fixedly mounted with a limit sleeve in chassis face, indicates disk by the way that support shaft is fixed in limit sleeve, Support shaft and limit sleeve clamp, and in cap top surface, coaxial welding two encloses protrusion, two circle bulge clearance certain distances, in two circle protrusions Between clamp instruction disk cover, instruction disk cover be connected and fixed with connector is projected through.

Moreover, it is to be formed with limited block in the inner wall of limit sleeve that the support shaft and limit sleeve, which clamp, made in support shaft There is limiting groove.

Moreover, the connector is bolt or buckle.

Moreover, the side wall radial symmetric in outer ring protrusion is formed with multiple threaded securing bores, it is radial in the outer wall of instruction disk cover Multiple tapped blind holes are symmetrically formed with, instruction disk cover is projected through with outer ring to be bolted.

The advantages and positive effects of the utility model are as follows:

1, this worm wheel head can be produced in batches with modular form, reduce manufacturing cost and mounting cost.

2, this worm wheel head need to only fix several bolts or buckle at housing, remaining is inserting, easy to operate, time saving province Power.

Detailed description of the invention

Fig. 1 is the main view of the utility model pointer worm wheel head；

Fig. 2 is the exploded view of the utility model pointer worm wheel head；

Fig. 3 is the A-A of the utility model pointer worm wheel head to cross-sectional view.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.

A kind of New type finger worm wheel head, including shell 1, cap 2, worm gear 13 and worm screw 6, worm gear and worm screw nibble in shell Connection is closed, the worm screw outside shell is fixedly mounted with handwheel 5, and worm gear is pierced by from cap, the top surface of worm gear and cap either flush, in snail The top surface of wheel is coaxially fixedly mounted with a chassis 12, is coaxially fixedly mounted with a limit sleeve 14 in chassis face, solid by support shaft 9 in limit sleeve Surely disk 7 is indicated, support shaft is fixedly mounted with the instruction face of trying to get to the heart of a matter, and support shaft and limit sleeve clamp, and the clamping is in limit sleeve Wall is formed with limited block 11, limiting groove 10 is formed in support shaft, rotation worm gear can make to indicate disk rotation, same in cap top surface Two circle protrusion 3 of axis welding, two circle bulge clearance certain distances, in outer ring, the side wall radial symmetric of protrusion is formed with multiple be screwed Hole 15.Instruction disk cover 4 is clamped between two circle protrusions, multiple tapped blind holes 8 is formed in the outer wall radial symmetric of instruction disk cover, refers to Show that disk cover is projected through with outer ring to be bolted.

Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field For personnel, under the premise of not departing from utility model design, various modifications and improvements can be made, these belong to this reality With novel protection scope.
