Description
Technical Field
The utility model relates to a fuel pump technical field, in particular to blanking cover structure for fuel pump pipeline is sealed.
Background
In the fuel pump industry, most of oil supply pipelines adopt circular tube type designs, and the conventional designs adopt steel balls or copper parts for interference fit sealing, so that the design has limitation, and when a non-circular tube (namely an oval) type pipeline is encountered, a plug cover seal with a corresponding shape cannot be processed or the cost is high due to difficulty in processing and manufacturing.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a blanking cover structure for fuel pump pipeline is sealed solves the sealed problem of non-circular pipe type fuel feed line, reduces the manufacturing cost of conventional blanking cover simultaneously.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a blanking cover structure for fuel pump pipeline is sealed, includes blanking cover body, support, be equipped with sealed pipeline in the support, the blanking cover body is installed in sealed pipeline, its characterized in that: the blanking cover body is designed symmetrically, one end of the blanking cover body is provided with a matching end matched with the inner wall of the sealed pipeline, a circle of protruding structure is arranged at the middle section of the matching end on the blanking cover body, the inner wall of the sealed pipeline is provided with a concave structure matched with the protruding structure, and the protruding structure and the concave structure are in interference fit.
By adopting the technical scheme, the two end structures of the plug body are the same as the matched pipeline structures, the middle section is raised by a circle of ribs for sealing and preventing falling, namely the raised structure, and the plug body adopts a symmetrical design to improve the assembly property of the plug body; the sealing pipeline matched with the plug cover body is provided with a circle of sunken structure and a circle of raised rib position which are just in interference fit, and the design purpose of sealing and preventing the falling off is achieved.
The utility model discloses further set up to: the blanking cover body is a cylinder with an oval cross section.
By adopting the technical scheme, the pipeline fitting device is used for matching with an oval pipeline.
The novel beneficial effect of this experiment does: the sealing problem of non-circular pipe type oil supply pipelines is solved, and the manufacturing cost of the conventional plugging cover is reduced.
The present invention will be further described with reference to the accompanying drawings.
