Problems solved by technology
However, in the process of lifting heavy objects by the engine crane, the operator can only swing the joystick up and down on the side of the crane to make the jack work. The staff cannot pump the jack smoothly due to lack of a suitable operating position, which affects the work process

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings of the embodiments, which will help the public to understand the technical content and effects of the present case, but the description of the embodiments does not constitute a restriction on the technical solution. Only the equivalent transformation in form should be regarded as the scope of the technical solution of this case.
[0017] It can be seen from the accompanying drawings that the embodiment of the present invention is a new swivel type structural scheme formed by redesigning the oil cylinder seat components on the basis of traditional hydraulic power components. The overall composition of this manual hydraulic jack with swivel structure is mainly There are: the oil cylinder part 23, the pump body part 21 and the oil cylinder base 1 are respectively connected with their respective thread pairs, and the top cap part 26 is used to fix the piston rod part 34 and th...

The invention discloses a manual hydraulic jack with a swivel structure, comprising an oil cylinder seat component, wherein the oil cylinder seat component is internally provided with an oil cylinder seat and a shaft coupling seat, a blind hole is arranged in the oil cylinder seat and is in clearance fit with the periphery of a shaft at the head part of the shaft coupling seat to form a revolute pair, a shoulder hole is arranged below the blind hole and used for accommodating a thrust roller bearing , a space ring, an elastic collar for the hole and a single-row radial ball bearing, a threaded hole and a bolt counter hole for loosening-preventing screwing with a screw thread pair 1 and a screw thread pair 2 for a set screw assembly 1 and a set screw assembly 2 are arranged on the oil cylinder seat, a shoulder outer circle 1, an axial locating slot, a shoulder outer circle 2, a shoulder outer circle 3, a shaft shoulder end face 1 and a shaft shoulder end face 2 are arranged on the periphery of the shaft coupling seat, and the shoulder outer circle 3 is in clearance fit with an implementing shaft hole of the shoulder hole. Since the traditional oil cylinder seat component is arranged into two parts rotatably coupled with a shaft hole, the transposition of a hydraulic power component is easily realized, and the jack is conveniently pumped by an operator in a suitable position.
Description
technical field [0001] The invention relates to a manual hydraulic power component of a hoisting machine, in particular to a manual hydraulic jack with a swivel structure matched to a similar engine hoist. Background technique [0002] Hydraulic power components have a wide range of applications. For example, manual hydraulic jacks are used in jacking motor vehicles and other occasions. They are light in weight, small in size and strong in applicability, and have been accepted by the public. With the extension of the application of this type of manual hydraulic jacks in lifting tools, there are many new uses for the structural functions of manual hydraulic jacks that are matched in various engine maintenance cranes. Generally speaking, in most engine cranes, mounting holes are directly machined at the base of the manual hydraulic jack and at the top of its piston rod, and the two ends of the manual hydraulic jack are connected in series to the fixed position of the crane wit...
