Abstract
The utility model discloses a connecting device for an engineering air compressor air pipe. The connecting device for the engineering air compressor air pipe comprises an upper rotating cover and a lower rotating cover. The whole of the upper rotating cover is in an annular cover-shaped structure, and an opening is formed in one side of the annular cover-shaped structure, the upper end of the upper rotating cover vertically extends upwards to form a fixed air pipe which is communicated with the upper rotating cover. The opening side of the upper rotating cover and an opening side of the lower rotating cover are clamped to form a whole and matches with each other in a rotary mode. The lower end of the lower rotating cover extends downwards to form an air pipe which is communicated with an air compressor. The connecting device for the engineering air compressor air pipe is simple in structure and convenient to use, not only achieves seamless connection of the compressor and the air pipes, but also rotates correspondingly according to the walking of a user, and effectively prevents a phenomenon that the air pipes are easily broken.
Description
Technical field
The utility model relates to engineering machinery field, is specifically related to a kind of engineering Windpipe connector for air compressor.
Background technique
flat board install complete after, in order to increase concrete formation intensity and the aesthetic measure after building, need to remain in the beam base plate, the foreign material such as wood chip the cleaning dull and stereotyped and part of encorbelmenting is clean, because the mostly colligation of reinforcing bar of this moment is complete, increased the difficulty of cleaning, the normal way that adopts is that leather hose is connected with the outlet side of air compressor, utilize the pressurized gas in air compressor progressively to blow out, but due to the job site circumstance complication, need to move frequently, and air compressor tracheae hardness is higher, in the process that the user uses its export with air compressor end of being connected can not dragging and rotate with the user, the phenomenon that crack or fracture appear in the end usually appears, and also be unfavorable for operator's operation.
The model utility content
The utility model purpose is to provide a kind of engineering Windpipe connector for air compressor, and it can solve existing problem in background technique effectively.
In order to solve existing problem in background technique, it comprises hub cap and lower hub cap, the integral body of described upper hub cap is the annular cover-shaped structure that a side is provided with opening, its upper end upwards vertically extends a fixedly tracheae, fixedly tracheae communicates with upper hub cap, opening one side of described upper hub cap and a side of lower hub cap opening are rotatably assorted between being buckled into after one, and the lower end of described lower hub cap is extended a steam outlet pipe that is communicated with air compressor downwards.
Opening one epitaxial lateral overgrowth of described upper hub cap stretches out a circle seam, the circle centre position of its other side offers keyhole, and offer the screw corresponding with it on lower hub cap, the screw coupling bar that doubles as rotating shaft inserts in keyhole, and self tapping screw is from being screwed in the end of screw coupling bar after screw inserts.
The internal diameter of the described lower hub cap applying screw cylindricality socket that extends internally out, described screw coupling bar integral body is the taper structure, the diameter of its front end is slightly less than the diameter of cylindricality socket, and the conical surface of described screw coupling bar is inserted in the cylindricality socket, and fixes by self tapping screw.
Owing to having adopted above technological scheme, the utlity model has following beneficial effect: simple in structure, easy to use, not only can realize the seamless link of air compressor and tracheae, can also be according to walking about of user and corresponding rotation, effectively prevented the phenomenon of tracheae frangibility.
Description of drawings
In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is done simple introduction.
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with in the utility model embodiment is clearly and completely described the technological scheme in the utility model embodiment.
Referring to Fig. 1, this embodiment is to be achieved by the following technical solutions, it comprises hub cap 1 and lower hub cap 2, the integral body of described upper hub cap 1 is the annular cover-shaped structure that a side is provided with opening, its upper end upwards vertically extends a fixedly tracheae 3, should be fixedly tracheae 3 communicate with upper hub cap 1, opening one side of described upper hub cap 1 and a side of lower hub cap 2 openings are rotatably assorted between being buckled into after one, the lower end of described lower hub cap 2 is extended a steam outlet pipe that is communicated with air compressor 5 downwards.
Opening one epitaxial lateral overgrowth of described upper hub cap 1 stretches out a circle seam 6, the circle centre position of its other side offers keyhole 4, and offer the screw corresponding with it 9 on lower hub cap 2, double as the screw coupling bar 7 of rotating shaft from the interior insertion of keyhole 4, self tapping screw 8 is from being screwed in the end of screw coupling bar 7 after screw 9 inserts.
The internal diameter of the described lower hub cap 2 applying screws 9 cylindricality socket that extends internally out, described screw coupling bar 7 integral body are the taper structure, the diameter of its front end is slightly less than the diameter of cylindricality socket, and the conical surface of described screw coupling bar 7 is inserted in the cylindricality socket, and fixing by self tapping screw 8.
Owing to having adopted above technological scheme, the utlity model has following beneficial effect: simple in structure, easy to use, not only can realize the seamless link of air compressor and tracheae, can also be according to walking about of user and corresponding rotation, effectively prevented the phenomenon of tracheae frangibility.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
