Embodiment

[0024] 1. Lifting operation:

[0025] Press the hydraulic piston 3 installed on the machine base 5 to make it move downward, and the hydraulic oil in the chamber A11 is squeezed into the chamber B10 through the oil circuit B12, the one-way valve group D20, the oil circuit C14, and the oil circuit D13 , the pressure in the chamber B10 increases, pushing the core tube 30, the mandrel 33, etc. to move upward. Loosen the oil pressure piston 3, under the action of the spring force of the return spring 8, the oil pressure piston 3 moves upward and reversely, the pressure in the chamber A11 decreases, the hydraulic oil in the chamber D1 passes through the oil circuit G2, the one-way valve group C6, and the oil Road A4 enters chamber A11.

[0026] The above steps are repeated, and the core tube 30, the mandrel 33, etc. are continuously raised. When the core tube 30 reaches the limit position, the core tube 30 stops rising, the volume of the chamber C24 starts to increase, and the co...

Abstract

The invention provides a medical jack and relates to the technical field of jacks. The medical jack comprises a machine seat. An oil way A, an oil way B, an oil way C, an oil way D, an oil way E, an oil way F, an oil way G and an oil way H are arranged in the machine seat. The machine seat is fixedly connected with an oil return one-way valve set A, an oil return speed adjusting valve set B, a one-way valve set C and a one-way set D. A sealed cavity D is formed among the machine seat, a jack seat, an inner tube and an outer tube. Hydraulic oil is filled into the cavity D. A cavity C is formed among a mandrel, a composite tube and a base. A cavity B is formed between the base and the machine seat. A cavity A is formed between the machine seat and a hydraulic piston. The medical jack has the advantages of being high in lifting efficiency, adjustable in unloading speed, long in lifting stroke and the like.

Description

Technical field: [0001] The invention relates to the technical field of jacks, in particular to a jack used for lifting medical equipment. Background technique: [0002] The manufacturing precision and manufacturing requirements of medical jacks are very high. It should be that medical jacks also have individualized function requirements, such as: 1. It can be raised quickly before use; 2. When in use, for height adjustment, the unloading speed is adjustable; 3. , For medical jacks, a larger stroke is required. At present, there are few manufacturers that actually produce medical jacks, and there are very few researches and innovations on medical jacks. Therefore, there is an urgent need for jacks that can meet the above needs at the same time. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the existing technical defects and provide a medical jack with reasonable structure, simple operation and convenient use. [00...
