Description
Technical Field
The utility model belongs to the technical field of the oil pump, refer in particular to an electronic oil pump that rises.
Background
At present, most of oil pumps rotate relative to a shell and a lifting rod, and the oil seal is short in service life and not easy to rotate due to the arrangement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a stable in structure, rotate light, oil blanket long service life's electronic oil pump that plays to rise.
The purpose of the utility model is realized like this: an electric lifting oil pump comprises an oil pump straight lug and a steering connecting rod arranged on one side of the oil pump straight lug, wherein a lifting cylinder penetrates through the oil pump straight lug, a lifting rod is arranged in the lifting cylinder, a convex column is formed on one side of the lifting cylinder, and a pressure bearing is sleeved on the convex column; the oil pump straight lug is provided with a groove clamped with the lifting cylinder, a clamping groove clamped with the convex column is formed in the groove, the inner wall of the groove is formed with a limiting convex ring, and a steering bearing is installed on the limiting convex ring and is arranged on the lifting cylinder.
Preferably, the lifting cylinder is formed with a thread, and the thread is screwed with a housing.
Preferably, an oil seal is arranged between the shell and the lifting rod.
Preferably, the housing is provided with an oil return hole.
Compared with the prior art, the utility model outstanding and profitable technological effect is: the utility model discloses an electronic lifting oil pump its relative rotation through straight ear of oil pump and lift cylinder when using has effectively avoided the relative rotation of shell and lifter, can increase the life of oil blanket to it rotates the convenient light that more adds.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
Detailed Description
The invention will be further described with reference to specific embodiments.
As shown in fig. 1-2, an electric lifting oil pump includes an oil pump straight lug 1 and a steering connecting rod 2 disposed at one side of the oil pump straight lug 1, a lifting cylinder 3 is disposed in the oil pump straight lug 1 in a penetrating manner, a lifting rod 4 is disposed in the lifting cylinder 3, a convex column 5 is formed at one side of the lifting cylinder 3, and a pressure bearing 6 is sleeved on the convex column 5; the oil pump straight ear 1 offers the recess 7 with 3 joints of lift cylinder, set up the draw-in groove 8 with 5 looks joints of projection in the recess 7, the shaping of recess 7 inner wall has spacing bulge loop 9, install on the spacing bulge loop 9 and turn to bearing 10, it establishes on lift cylinder 3 to turn to bearing 10.
When the electric lifting oil pump is used, the relative rotation of the straight lug 1 of the oil pump and the lifting cylinder 3 is effectively avoided, the relative rotation of the shell 12 and the lifting rod 4 is effectively avoided, the service life of the oil seal 13 can be prolonged, and the rotation of the electric lifting oil pump is more convenient and easy.
Preferably, the lifting cylinder 3 is formed with a thread 11, and the thread 11 is screwed with a housing 12. The shell is installed through the threads 11, so that the shell is convenient to disassemble, assemble and maintain, convenient to transport and capable of reducing occupied space.
Preferably, an oil seal 13 is provided between the housing 12 and the lifter 4. The oil seal 13 can increase the sealing performance and prolong the service life of the oil seal.
Preferably, the housing 12 is provided with an oil return hole 14. The hole 14 is used for limiting an oil return hole when the oil pump piston reaches a certain height, and when the oil pump piston reaches the position, the rising oil starts to flow back to prevent the oil from rising continuously to cause the phenomenon of over-head rising to cause accidents.
The above embodiment is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited in this way, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
