The invention relates to an integral oiling pump handle and back cover. The integral oiling pump handle and back cover comprises a back cover, a handle, a large cover plate and a small cover plate; the handle is vertically inserted in the small cover plate, and is fixed by a screw through a step hole at the upper end of the back cover; a cylinder is arranged at the lower part of the back cover; left and right two symmetric columns are arranged in the cylinder; second through holes are formed in the columns; a first square groove is formed in the back end of the back cover; a ring of grooves is formed in the back end of the first square groove; small circular holes are vertically inserted in the grooves; the large cover plate is arranged at the back end of the first square groove; left-right symmetric second step holes are distributed around the large cover plate; and the large cover plate is fixed by screws through the second step holes and the small circular holes. Generally, the integral oiling pump handle and back cover has the advantages of simple structure, convenience for disassembly, integration of an oil pumping with the back cover and the handle, convenience for carrying and small size.
Description
technical field [0001] The invention relates to the field of fuel supply equipment, in particular to an integrated fuel pump handle and rear cover. Background technique [0002] As a kind of equipment mainly used to transport oil, the fuel pump is widely used in various domestic industries. It is an indispensable oil transport and refueling tool in workshops, gas stations, airports, laboratories, etc. of various enterprises. During the actual use of the fuel pump, sometimes there will be situations that seriously affect the service life of the pump body, such as: the oil-free dry running of the pump body due to the emptying of the oil barrel during the delivery of oil; The actual situation such as the overload operation of the oil pump; the existing equipment, the oil pump with the control system is not convenient to carry, and the easy-to-carry oil pump cannot be controlled intelligently and flexibly. For small mechanical equipment, the installation space of the existing eq...
