Abstract
The utility model relates to a manual high-pressure oil pump. The oil pump consists of a pump body and a plunger and is characterized in that: the front end of the pump body is provided with a distributer; the back end of the pump body is connected with an oil tank; and the plunger is a step cylinder. Therefore, the manual high-pressure oil pump has the advantages of simple structure, convenient manufacture, increasing the oil discharge amount and the work efficiency at the same time.
Description
Technical field:
The utility model relates to a kind of high pressure manual oil pump, belongs to oil pump and makes the field.
Technical background
At present, the high pressure manual oil pump mainly contains the pump housing and the plunger two large divisions forms, and the pressure gauge that directly is connected with the pump housing is equipped with in pump housing upper end; The front end of the pump housing is equipped with delivery connection, outwards provides hydraulic coupling by coupled high-pressure oil pipe.Plunger in the pump housing is a cylindrical body, and moving up and down in the pump housing by coupled operating grip produces hydraulic coupling.There is the defective of two aspects in this high pressure manual oil pump, and the one, pressure gauge is located immediately on the pump housing, and pump housing inner chamber structure is complicated, and manufacturing has increased difficulty to the pump housing; The 2nd, plunger is a cylindrical body, and oil drain quantity is little, inefficiency.
Summary of the invention
For overcoming the deficiency that existing high pressure manual oil pump exists, the utility model provides a kind of high pressure manual oil pump, and it is made up of the pump housing and plunger, it is characterized in that: described pump housing front end is equipped with a distributor, and described pump housing rear end is connected with fuel tank; Described plunger is a step cylindrical body.
Described distributor is provided with an oil inlet hole that is connected with pump housing hydraulic oil oil outlet and two oil outlets that are connected with described oil inlet hole respectively, and, one of them oil outlet is used to connect the delivery connection of exporting hydraulic oil, and another oil outlet then is used to connect pressure gauge.
Described step cylindrical body is formed by big small cylinder is coaxial.
The cylindrical end of described step is connected with operating grip.
Advantage of the present utility model is: the one, and pressure gauge no longer directly is connected with the pump housing, and pump housing inner-cavity structure is simple, and is easily manufactured, improved manufacturing efficiency; The 2nd, plunger is made cylindrical body with the level, has increased plunger and has sent oil mass, has promptly increased the oil drain quantity of high pressure manual oil pump, has improved working efficiency.

Embodiment
Describe technological scheme of the present invention in detail below in conjunction with accompanying drawing.
The utility model provides a kind of high pressure manual oil pump, and it is made up of the pump housing 5 and plunger 8 two large divisions.Wherein, plunger 8 is one, and small cylinder is down by two coaxial step cylindrical bodys of forming of cylindrical body of size, and large cylinder is last, and the one end is connected with operator 1 handle, by the whole step cylindrical body of the operating grip 1 drive generation oil pressure that moves up and down.Yet, front end at the pump housing 5 is installed a distributor 4, an oil inlet hole that is connected with the pump housing 5 hydraulic oil oil outlets and two oil outlets that are connected with described oil inlet hole are respectively arranged on this distributor 4, and one of them oil outlet is connected in the delivery connection 3 of hydraulic oil; Another oil outlet then is connected in pressure gauge 2, for the ease of showing oil pressure.And the rear end of the pump housing 5 is to be connected with fuel tank 6.Like this, pressure gauge 2 directly is not connected with the pump housing 5, and the pump housing 5 inner-cavity structures are simple relatively, improved manufacturing efficiency.
