Description

A kind of fire hydrant

Technical field

The utility model relates to fire-protection equipment field, specifically a kind of fire hydrant.

Background technique

Fire hydrant is the structure member for connecting fire gear and water outlet leather hose on fire-protection equipment such as fire hydrant, its needs provide connection speed easily, there is provided reliable main officer of Tibet connectivity again simultaneously, therefore, need to improve fire hydrant to realize its function better.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of fire hydrant, and its structure is simple, good reliability.

The utility model solves the technological scheme that its technical problem adopts:

A kind of fire hydrant, comprise the main body of cast, described main body two ends are respectively front-end and back-end, described front end outer wall are provided with the groove of arc, and the outer wall of the forward end side of described groove is provided with the step of screens, described rear end inwall is stepped shaft.

As the improvement of technique scheme, described front edge is provided with chamfering in inside and outside both sides.

As the further improvement of technique scheme, on described front edge, the chamfering of inner side is 60 °, and the chamfering in outside is 65 °.

Further, described back edge is extended with 4 edges toward outside, the symmetrical equidistant setting of described edge.

Further, described edge is provided with draw-in groove, described draw-in groove is corresponding to main body perisporium.

The beneficial effects of the utility model are: this product structure is simple, and good reliability, can bear powerful hydraulic pressure, realize suppressing water outlet, and conveniently connect, guarantee to have good switching performance simultaneously.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is broken section left view of the present utility model;

Fig. 2 is plan view of the present utility model.

Embodiment

See figures.1.and.2, a kind of fire hydrant of the present utility model, comprise the main body 1 of cast, described main body 1 two ends are respectively front end 11 and rear end 12, described front end 11 outer wall is provided with the groove 13 of arc, groove 13 is convenient to slip into other parts of socket when connecting, the outer wall of described recessed 13 forward end 11 sides is provided with the step 14 of screens, by step 14 fit 13, external component is socketed on groove 13 then to be clamped by step 14, described rear end 12 inwall is stepped shaft, inwall is radial toward extension in side, rear end 12, coupling socket outer tube.

As the improvement of above-mentioned mode of execution, edge is provided with chamfering in inside and outside both sides in described front end 11, improves guiding grafting convenience during assembling better.

As the further improvement of above-mentioned mode of execution, preferably, on edge, described front end 11, the chamfering of inner side is 60 °, and the chamfering in outside is 65 °.

Further, edge, described rear end 12 is extended with 4 edges 15 toward outside, the symmetrical equidistant setting of described edge 15, during connection, edge 15 can achieve a butt joint flexibly, joint outer part only needs corresponding two edges 15 wherein to carry out structure correspondence, and edge 15 edge is the concentric circle arc of main body 1, therefore edge rotates and fastens clamping.

Further, described edge 15 is provided with draw-in groove 16, described draw-in groove 16 correspondence is perpendicular to main body 1 perisporium, and draw-in groove 16 may correspond to and snaps in bolt or other protruding structure thus strengthen further connecting tightness.

The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should fall within protection domain of the present utility model.
