However, this structure is suitable for use in a smaller space, which causes limitations when the device is used. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wedge-shaped hydraulic jack, aiming to solve the problems raised in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a wedge-shaped hydraulic jack, comprising a base, on which a jacking assembly is arranged; The lifting assembly comprises a reinforced sealing transfer frame arranged in the middle of the base, a guide cylinder is arranged on one side of the reinforced sealing transfer frame, the reinforced sealing transfer frame is connected with the guide cylinder, an extension rod is slidably connected in the guide cylinder, and a limit pin is sleeved on one end of the extension rod; The base is provided with an angle-adjustable reinforced triangular lifting block, both ends of the limit pin are rotatably connected to a traction rod body, and one end of each traction rod body extends to the bottom of the reinforced triangular lifting block and is rotatably connected to the reinforced triangular lifting block; The vertical cross-section shape of the reinforced triangular lifting block is set to be a triangle, and a rotating rod is embedded in one end of the reinforced triangular lifting block, and the rotating rod is rotatably connected to the reinforced triangular lifting block. Limiting sleeves are fixedly provided on both sides of the base, and a rotating shaft is rotatably connected in the limiting sleeve, and the rotating shaft is fixedly provided on the reinforced triangular lifting block.

[0006] It can be seen that in the above technical solution, when the extension rod is extended, it will drive the limit pin to move, thereby enabling the traction rod body to pull the reinforced triangular lifting block to deflect along the axial point of the connection between the rotating shaft and the limit sleeve, thereby enabling the reinforced triangular lifting block to be tilted and lifted.

[0007] Optionally, in a possible implementation, a hydraulic cylinder body is provided on one side of the surface of the base, a handle is hinged on the hydraulic cylinder body, a regulating valve is provided on one end of the hydraulic cylinder body, the regulating valve is communicated with the hydraulic cylinder body, a valve stem body for flow regulation is rotatably connected to the regulating valve, a first reinforced delivery pipe is provided on the regulating valve, a second reinforced delivery pipe is provided on the top of the first reinforced delivery pipe, the first reinforced delivery pipe and the second reinforced delivery pipe are both communicated with the regulating valve, the first reinforced delivery pipe and the second reinforced delivery pipe extend to the reinforced sealing transfer frame at one end away from the regulating valve, and two through holes respectively communicated with the first reinforced delivery pipe and the second reinforced delivery pipe are provided on the outer side of the reinforced sealing transfer frame; It can be seen that in the above technical solution, repeatedly turning the handle allows the oil in the hydraulic cylinder body to be transported to the first reinforced delivery pipe through the regulating valve, and the oil is transported to the reinforced sealing transfer frame and the guide cylinder through the first reinforced delivery pipe, so that the extension rod can be extended along the guide of the guide cylinder, and the flow rate of the oil transported to the regulating valve through the hydraulic cylinder body can be adjusted through the valve stem body, which makes it easy to fine-tune the stroke of the reinforced triangular lifting block when lifting, thereby improving the accuracy of lifting the workpiece.

[0009] Technical effects and advantages of the present invention: 1. The present invention repeatedly turns the handle so that the oil in the hydraulic cylinder body can be transported to the first reinforced delivery pipe through the regulating valve, and the oil is transported to the reinforced sealing transfer frame and the guide cylinder through the first reinforced delivery pipe, so that the extension rod can be extended along the guide of the guide cylinder. When the extension rod is extended, it will drive the limit pin to move, and then the traction rod body pulls the reinforced triangular lifting block to deflect along the axis point of the connection between the rotating shaft and the limit sleeve, and then the reinforced triangular lifting block can be tilted and lifted, and then the function of lifting the workpiece is realized; 2. The present invention adjusts the flow rate of the oil delivered to the regulating valve through the valve stem body through the hydraulic cylinder body, which is easy to fine-tune the stroke of the reinforced triangular lifting block when lifting, thereby improving the accuracy of the workpiece when lifting.

When the second gear of the present invention rotates, it drives the screw to rotate in the supporting swivel. When the screw rotates, the sealing baffle is displaced up and down in the reinforced sealing transfer frame by the traction force of the screw when the screw rotates, so as to realize the function of adjusting the position of the sealing baffle. The first reinforced delivery pipe and the second reinforced delivery pipe are blocked by the displacement of the sealing baffle, which can effectively avoid the phenomenon of oil backflow during delivery, and ensure the stability of the reinforced triangular lifting block when supporting the workpiece; To sum up, the overall design is simple and the structure is reasonable.
