Specific embodiment

In order that the purpose of this utility model and advantage become more apparent, the utility model is entered with reference to embodiments Row is further described.It should be appreciated that specific embodiment described herein is only used to explain the utility model, and without In restriction the utility model.

As depicted in figs. 1 and 2, the utility model embodiment provides a kind of new oil transfer pump, including the pump housing 1, the pump An inflow pipeline 2 is provided with body 1, the upper end of the pump housing 1 fixedly mounts a sealed cylinder 16, and the upper end of sealed cylinder 16 is provided with a through hole 7, be provided with a piston 9 in the body of sealing drum 16, vertical one straight-bar 6 of fixed installation in the upper surface middle of piston 9, the upper end of straight-bar 6 along Through hole 7 extends to the external world, and fixedly mounts a cross bar 5, and straight-bar 6 is located on the one end in sealed cylinder 16 and is cased with one first spring 8, the lower end of the first spring 8 is fixedly connected with the upper surface of piston 9, and the upper end of the first spring 8 is consolidated with the top surface inside sealed cylinder 16 Fixed connection, the lower end of sealed cylinder 16 fixedly mounts an oil pipe 13, and the lower end of oil pipe 13 extends to the oil-feed in the pump housing 1 through the pump housing 1 In body 2, the openend of the upper end of oil pipe 13 is inserted into a sealing-plug 15, and the opening of the upper end of oil pipe 13 is by described sealing-plug 15 Sealing, the inner bottom surface of the sealed cylinder 16 is located at and a support 10, the L-shaped structure of support 10 is fixedly mounted at sealing-plug 15 Set, support 10 is right against one second spring 11 of fixed installation, the lower end of second spring 11 and described sealing at sealing-plug 15 Plug 15 is fixedly connected.

In the present embodiment, the upper end of the pump housing 1 is located at the left side of sealed cylinder 16 and fixedly mounts a fixed block 3, the upper end of fixed block 3 A cylinder 4 is fixedly mounted, the telescopic end of cylinder 4 is fixedly connected with the lower surface of cross bar 5.
