Description

Technical Field

[0001] This invention relates to the field of jack technology, and more particularly to a horizontal hydraulic jack. Background Technology

[0002] Horizontal jacks are important hydraulic components widely used in heavy-duty vehicles or mobile equipment to support the weight of the equipment and adjust its level. They are mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and supporting work. When supporting and lifting objects with many electrical components, the support point cannot be seen, which may damage important components during lifting and supporting. It is necessary to observe the support point. Existing jacks do not have the function of observing the bottom environment or adjustment function. Summary of the Invention

[0003] To address the technical problems existing in the background art, the present invention proposes a horizontal hydraulic jack.

[0004] This invention proposes a horizontal hydraulic jack, comprising a U-shaped base frame, a top frame, a support head, a lifting control, and a handle. The top frame is hinged to a groove in the U-shaped base frame, the support head is installed on the top of the top frame, and the handle is detachably connected to the lifting control. A U-shaped frame is rotatably connected to the top of the U-shaped base frame near the lifting control. The top frame can be freely raised and lowered in the groove of the U-shaped frame. A flipping mechanism is provided on the U-shaped base frame for flipping the U-shaped frame. Reflectors are installed on the upper sides of the two sets of parallel frame bodies of the U-shaped frame.

[0005] Preferably, the flipping mechanism includes a rotating rod, two sets of lead screws and a rotating cylinder, the U-shaped base frame has a built-in cavity, the two sets of parallel frames of the U-shaped base frame are the first frame, and the frame connecting the two sets of the first frame is the second frame;

[0006] The two sets of lead screws are respectively located in the inner cavity of the two sets of first frame bodies. Limiting grooves are opened on the upper side of the two sets of first frame bodies. The limiting grooves are parallel to the corresponding lead screws. Each set of limiting grooves is slidably connected to a moving block. The moving block is threadedly connected to the corresponding lead screw. The rotating rod is located in the inner cavity of the second frame body. Both ends of the rotating rod are fixedly connected to a first bevel gear. The end of the two sets of lead screws near the second frame body is fixedly connected to a second bevel gear. The first bevel gear and the corresponding second bevel gear of each set of rotating rods mesh with each other.

[0007] A rotating cylinder is installed at an angle in the middle of the second frame. The outer wall of the rotating cylinder can rotate on the second frame. A drive gear is installed in the part of the rotating cylinder located in the inner cavity of the second frame. The drive gear meshes with a worm gear. The part of the rotating cylinder located outside the second frame can be detachably connected to a handle.

[0008] Preferably, both sets of the moving blocks are equipped with rollers, and the two sets of rollers are located on the bottom sides of the U-shaped frame that are parallel to each other.

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

[0010] Preferably, the bottom of the U-shaped base frame is equipped with four sets of casters.

[0011] Preferably, the upper surface of the top frame is equipped with supplementary LED lights.

[0012] Preferably, a rubber pad is installed on the top of the support head.

[0013] Preferably, a handle is attached to the end of the handle.

[0014] This invention proposes a horizontal hydraulic jack with a tilting mechanism that can be used to tilt the rotation angle of a U-shaped frame. A reflector is installed on the U-shaped frame, allowing the jack to see the bottom of the object being lifted when it moves to the bottom, thus preventing blind spots and ensuring the jack avoids damaging critical components during lifting. The handle can be inserted into the lifting control and pressed back and forth to lift the jack. Alternatively, it can be inserted into the rotating drum, and rotating the handle engages the drive gear and worm gear on the drum, thereby driving the rotating drum... The rod rotates, and the first bevel gear at each end of the rod meshes with the corresponding second bevel gear, thereby driving the lead screw to rotate. Under the limiting action of the limiting groove, the lead screw can drive the moving block to move. Since the U-shaped frame is hinged to the U-shaped base frame, the moving block is located at the bottom of the U-shaped frame and plays a supporting role. When the moving block is away from the pivot of the U-shaped frame, the tilt angle of the U-shaped frame is small. When the moving block is close to the pivot of the U-shaped frame, the tilt angle of the U-shaped frame is large. By changing the tilt angle of the reflector through the U-shaped frame, the viewing angle of the reflection is changed, making it convenient for the user to observe the bottom of the object to be lifted.

[0015] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figures 1-6 The horizontal hydraulic jack shown includes a U-shaped base frame 1, a top frame 101, a support head 102, a lifting control 105, and a handle 7. The top frame 101 is hinged in the groove of the U-shaped base frame 1. The support head 102 is installed on the top of the top frame 101. The handle 7 is detachably connected to the lifting control 105. A U-shaped frame 2 is rotatably connected to the top of the U-shaped base frame 1 near the lifting control 105. The top frame 101 can be freely raised and lowered in the groove of the U-shaped frame 2. The U-shaped base frame 1 is provided with a flipping mechanism for flipping the U-shaped frame 2. Reflectors 201 are installed on the upper sides of the two sets of parallel frames of the U-shaped frame 2.

[0026] The flipping mechanism can be used to flip the rotation angle of the U-shaped frame 2. A reflector 201 is installed on the U-shaped frame 2. When the jack moves to the bottom of the object to be lifted, the bottom scene of the object to be lifted can be seen through the reflector 201, so as to observe the bottom situation in time and avoid blind spots. This ensures that the top frame 101 avoids important components when lifting and avoids damage.

[0027] Preferably, the flipping mechanism includes a rotating rod 4, two sets of lead screws 5 and a rotating cylinder 3, the U-shaped base frame 1 has a built-in cavity, the two sets of parallel frames of the U-shaped base frame 1 are the first frame, and the frame connecting the two sets of the first frame is the second frame;

[0028] The two sets of lead screws 5 are respectively located in the inner cavity of the two sets of first frame bodies. Limiting grooves 106 are opened on the upper side of the two sets of first frame bodies. The limiting grooves 106 are parallel to the corresponding lead screws 5. Each set of limiting grooves 106 is slidably connected to a moving block 6. The moving block 6 is threadedly connected to the corresponding lead screw 5. The rotating rod 4 is located in the inner cavity of the second frame body. Both ends of the rotating rod 4 are fixedly connected to a first bevel gear 402. The ends of the two sets of lead screws 5 near the second frame body are fixedly connected to a second bevel gear 501. The first bevel gear 402 of each set of rotating rods 4 meshes with the corresponding second bevel gear 501.

[0029] A rotating cylinder 3 is installed at an incline in the middle of the second frame. The outer wall of the rotating cylinder 3 can rotate on the second frame. A drive gear 301 is installed on the part of the rotating cylinder 3 located in the inner cavity of the second frame. The drive gear 301 meshes with the worm gear 401. The part of the rotating cylinder 3 located outside the second frame can be detachably connected to the handle 7.

[0030] When the handle 7 is inserted into the lifting control 105, pressing the handle 7 back and forth can lift the top frame 101. Alternatively, it can be inserted into the rotating drum 3, and rotating the handle 7 will cause the rotating rod 4 to rotate through the meshing of the drive gear 301 and the worm gear 401 on the rotating drum 3. The first bevel gear 402 at both ends of the rotating rod 4 meshes with the corresponding second bevel gear 501, thereby driving the lead screw 5 to rotate. Under the limiting action of the limiting groove 106, the lead screw 5 can drive the moving block 6 to move. Since the U-shaped frame 2 is hinged to the U-shaped base frame 1, the moving block 6 is located at the bottom of the U-shaped frame 2 and plays a supporting role. When the moving block 6 is away from the pivot of the U-shaped frame 2, the tilt angle of the U-shaped frame 2 is small. When the moving block 6 is close to the pivot of the U-shaped frame 2, the tilt angle of the U-shaped frame 2 is large. By changing the tilt angle of the reflector 201 through the U-shaped frame 2, the viewing angle of the reflection is changed, making it convenient for the user to observe the bottom of the object to be lifted.

[0031] Preferably, both sets of the moving blocks 6 are equipped with rollers 601, and the two sets of rollers 601 are respectively located on the bottom sides of the parallel frame of the U-shaped frame 2, which can reduce the frictional resistance between the moving blocks 6 and the U-shaped frame 2 during the movement of the moving blocks 6.

[0032] Preferably, the upper surface of the U-shaped base frame 1 is inclined. When the moving block 6 is located at the end away from the rotating cylinder 3, the U-shaped frame 2 remains horizontal. When the moving block 6 is located at the end close to the rotating cylinder 3, the inclination angle of the U-shaped frame 2 is at its maximum.

[0033] Preferably, the bottom of the U-shaped base frame 1 is equipped with four sets of casters 104 for movement and transportation.

[0034] Preferably, the upper surface of the top frame 101 is equipped with a supplementary LED light 107, which can provide supplementary lighting in dim environments.

[0035] Preferably, a rubber pad 103 is installed on the top of the support head 102, which can serve as a buffer and protection function.

[0036] Preferably, the end of the handle 7 is equipped with a handle 701 for easy operation and grip.
