[0002] A horizontal jack is an important hydraulic component widely used in load-carrying vehicles or mobile equipment to support the weight of the equipment and adjust the level of the equipment. It is mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and supporting work. When the jack is supporting and lifting objects with more circuit components, the support point cannot be seen, and important components may be damaged during lifting and supporting. It is necessary to observe the support point. The existing jacks do not have the function of observing the bottom environment, nor do they have the adjustment function. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention provides a horizontal hydraulic jack.

[0004] A horizontal hydraulic jack proposed in the present invention comprises a U-shaped base frame, a top frame, a supporting head, a lifting control and a handle, wherein the top frame is hinged in a groove of the U-shaped base frame, the supporting head is installed on the top of the top frame, the handle is detachably connected to the lifting control, the top of the U-shaped base frame near one end of the lifting control is rotatably connected to the U-shaped frame, the top frame can be freely lifted and lowered at the groove of the U-shaped frame, a flipping mechanism is provided on the U-shaped base frame for flipping the U-shaped frame, and reflectors are installed on the upper sides of two sets of parallel frames of the U-shaped frame.

[0005] Preferably, the flip mechanism comprises a rotating rod, two sets of screw rods and a rotating drum, the U-shaped base frame has a built-in cavity, the two sets of mutually parallel frames of the U-shaped base frame are the first frame, and the frame connecting the two sets of first frames is the second frame;

[0006] The two groups of screw rods are respectively located in the inner cavities of the two groups of the first frames, and limiting grooves are provided on the upper sides of the two groups of the first frames, and the limiting grooves are parallel to the corresponding screw rods, and each group of the limiting grooves is slidably connected with a moving block, and the moving block is threadedly connected with the corresponding screw rod, and the rotating rod is located in the inner cavity of the second frame, and both ends of the rotating rod are fixedly connected with the first bevel gear, and one end of the two groups of screw rods close to the second frame is fixedly connected with the second bevel gear, and the first bevel gear of each group of the rotating rods is meshed with the corresponding second bevel gear;

[0007] A rotating drum is obliquely installed in the middle of the second frame, and the outer wall of the rotating drum can rotate on the second frame. A driving gear is installed on the part of the rotating drum located in the inner cavity of the second frame, and the driving gear is meshed with the turbine. The part of the rotating drum located outside the second frame can be detachably connected to the handle.

[0008] Preferably, rollers are installed on both groups of moving blocks, and the two groups of rollers are respectively located on the bottom sides of the U-shaped frame body which are parallel to each other.

[0009] Preferably, the upper surface of the U-shaped base frame is inclined, and when the moving block is located at the end away from the drum, the U-shaped frame remains horizontal, and when the moving block is located at the end close to the drum, the inclination angle of the U-shaped frame is maximum.

It can ensure that the top frame avoids important components when lifting and avoids damage. When the handle is inserted into the lifting control, the handle is pressed back and forth to lift the top frame, and it can also be inserted into the rotating drum and the handle is rotated to drive the rotary drum through the engagement of the driving gear on the rotating drum with the turbine. The rod rotates, and the first bevel gears at both ends of the rotating rod mesh with the corresponding second bevel gears, thereby driving the screw rod to rotate. Under the limiting action of the limiting groove, the moving block can be driven to move through the screw rod; since the U-shaped frame is hinged on the U-shaped base frame, the moving block is located at the bottom of the U-shaped frame to play a supporting role.
