Description

Part of the vacuum pumping unit

This creation is about a vacuum pumping unit used in oil extraction.

From the various views, the main appearance features are: the pumping unit of this creation mainly has a cylindrical body with an elliptical cross-section, and the outer circumference of the cylindrical body is equidistant with several annular ribs. Four bases in the shape of triangular bumps are arranged radially. The upper part of the cylinder body is formed upward to form a tapered cone. The upper cylinder body has a recessed side on one side. The recessed portion is provided with an upright handle, and the side of the barrel corresponding to the upright handle is further provided with a storage tube, and the top of the upper barrel is provided with a cover, and the center of the cover A raised part is arranged from the long diameter position, and a vacuum pull handle is arranged at the center of the raised part. One end of the raised part has a side frame that can restrict the vacuum pull handle. The side frame has a side The hollow part of the hollow part is provided with an inverted L-shaped connecting tube, one end of the connecting tube has a screw connection part and protruding outside the side frame, the other end of the protruding part has a knob, and the outer circumference of the knob There are several longitudinal grooves, and both ends of the cover body are provided with three concave arcs along the edges, which presents a novel and special visual perception as a whole. It is a part of the design of a vacuum pumping unit, as disclosed in the figure The dotted line part is the part of this case that does not advocate design. The above should have met the requirements for establishing a design patent. An application is filed according to the law, and I hope that the Bureau will grant the patent as soon as possible.
