Embodiment 1

[0016] like figure 1 An easy-to-operate hydraulic manual pump shown includes a valve body 1, on which a piston mechanism 2 and an oil inlet passage 3 and an oil outlet passage 4 connected with the piston mechanism 2 are arranged, and the oil inlet passage The oil inlet is connected to the oil inlet through the oil inlet control check valve, and the oil outlet is connected to the oil outlet through the oil outlet control check valve. The piston mechanism 2 is provided with a piston pulling device; the piston pulling device includes a The fixing part 51 on the valve body 1 , the pull rod 52 with one end movably arranged on the fixing part 51 , and the transmission rod 53 for connecting the pull rod 52 and the piston mechanism 2 . The fixing member 51 and the pull rod 52 can be connected in a hinged manner. The principle mode of oil inlet and oil outlet of the device is the same as that of the prior art. The oil outlet control check valve and the oil inlet control check valve r...

Embodiment 2

[0018] like figure 1 An easy-to-operate hydraulic manual pump shown in this embodiment is optimized on the basis of the above embodiments, that is, the two ends of the transmission rod 53 are hinged to the pull rod 52 and the piston mechanism 2 respectively.

[0019] One end of the transmission rod 53 is fixed on the middle section of the pull rod 52 . The length of the transmission rod can be specifically set according to the usage conditions, and the position where the transmission rod is fixed on the pull rod can also be adjusted. The strength of lifting or pressing the operating end can be adjusted by adjusting the length of the transmission rod and the fixed position of the transmission rod on the pull rod. Setting the transmission rod at the middle section of the tie rod can save half the force.

Abstract

The invention discloses a hydraulic manual pump easy to operate. The hydraulic manual pump easy to operate comprises a valve body. A piston mechanism, an oil inlet channel and an oil outlet channel are arranged on the valve body, wherein the oil inlet channel and the oil outlet channel are connected with the piston mechanism. The oil inlet channel is connected with an oil inlet through an oil inlet control one-way valve. The oil outlet channel is connected with an oil outlet through an oil outlet control one-way valve. A piston pulling device is arranged on the piston mechanism. The piston pulling device comprises a fixing part arranged on the valve body, a pull rod with one end movably arranged on the fixing part, and a transmission rod used for being connected with the pull rod and the piston mechanism. The hydraulic manual pump is easy to operate.

Description

technical field [0001] The invention relates to the field of hydraulic system devices, in particular to an easy-to-operate hydraulic manual pump. Background technique [0002] The working principle of the easy-to-operate hydraulic hand pump is that the mechanical energy generated by people doing work is converted into the pressure energy of the liquid. The easy-to-operate hydraulic hand pump has the advantages of small size and good portability, so the application of the easy-to-operate hydraulic hand pump is more and more extensive. [0003] At present, the hydraulic manual valves on the market use a piston mechanism to realize oil inlet and outlet. It is necessary to press or lift the pressure head of the piston mechanism, and the operation is laborious. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides an easy-to-operate hydraulic manual pump, which is easy to operate. [0005] The technical solution ado...
