Description

Technical Field

[0001] The utility model relates to the technical field of jacks, in particular to a high-stability anti-tilt hydraulic jack. Background Art

[0002] A jack is a lightweight lifting device that uses a rigid lifting member as a working mechanism to lift heavy objects within a short stroke of a top support or bottom claw. Jacks are primarily used in factories, mines, transportation, and other sectors for vehicle repair and other lifting and supporting tasks. Their lightweight, sturdy structure is flexible and reliable, and can be carried and operated by one person.

[0003] When the jack is in use, its bottom is placed on the ground and the output end is located at the top, that is, when in use, its output end moves upward to lift the heavy object above. However, in actual use, the installation ground is not flat, especially when used outdoors. The uneven ground causes the jack to tilt easily during use, thereby causing harm to people. A solution is proposed below to address the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a high-stability anti-tilt hydraulic jack to solve the problems raised in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A high-stability anti-tilt hydraulic jack includes a jack body, the lower end of the jack body is fixedly connected to a base, a water tank is provided on the base, a transparent baffle is provided above the water tank, the transparent baffle and the base are fixedly connected, an upper support rod is hinged on the side of the jack body, a first threaded hole is provided in the upper support rod, a rotating block is threadedly connected to the first threaded rod, a through hole is provided on the rotating block, a hand rod is movably connected in the through hole, a lower support rod is provided at the lower end of the rotating block, a second threaded hole is provided on the lower support rod, the lower end of the rotating block is threadedly connected to the second threaded hole, and the end of the lower support rod is hinged to a support seat.

[0007] The above technical solution is adopted, a base is provided under the jack body to increase the contact area with the ground and increase the stability of the jack. A water tank is also provided on the base. A certain volume of liquid is injected into the water tank to cause bubbles to appear inside it. The position of the bubbles is observed through a transparent baffle to determine whether the base is level to ensure the levelness of the jack body. An upper support rod, a rotating block and a lower support rod are provided on the side of the jack body. The three parts constitute an adjustment assembly, which supports the side of the jack in cooperation with the support seat and can also adjust the inclination angle of the jack. By inserting the hand rod into the through hole on the rotating block and twisting the hand rod, the rotating block is driven to rotate. The rotating rod and the upper support rod and the lower support rod are threadedly matched, so that the upper support rod and the lower support rod move toward or away from each other to adjust the distance between the hinge point of the upper support rod and the jack body and the hinge point of the lower support rod and the support seat, so as to support the jack and achieve fine-tuning of the angle of the jack body. The hand rod is detachable to avoid interference with the use of the jack after adjustment.

[0008] Preferably, a plurality of anti-slip nails are fixedly connected to the bottom of the base, and a plurality of anti-slip nails are fixedly connected to the bottom of the support seat.

[0009] With the above technical solution, anti-slip nails are fixedly connected to the bottom of the base and the bottom of the support seat. When using the jack, the anti-slip nails are inserted into the ground to prevent the base and the support seat from displacement, thereby ensuring safety.

[0010] Preferably, both ends of the rotating block are fixedly connected to limit blocks.

[0011] With the above technical solution, the limit blocks at both ends of the rotating block are respectively located inside the upper support rod and the lower support rod, preventing the rotating rod from rotating excessively and causing the connection between the upper support rod and the lower support rod to fall off.

[0012] Preferably, reinforcing ribs are provided between the base and the jack body, and the reinforcing ribs are fixedly connected to the jack body and the base respectively.

[0013] By adopting the above technical solution, the reinforcing ribs make the connection between the base and the jack body more stable, further enhancing the stability of the jack.

[0014] Beneficial effects: 1. The upper support rod, rotating block, lower support rod and support base form an adjustment component, which not only supports the jack body, but also can adjust the angle of the jack body to ensure the horizontality of the jack body.

[0015] 2. There is a base connected to the bottom of the jack body. The base is used to increase the contact area between the jack body and the ground, which can improve the stability of the jack.

[0016] 3. The lower ends of the base and the support seat are fixedly connected with anti-slip nails, which prevent the jack from being displaced by force and ensure the safety of the jack when working.

[0017] 4. There is a water tank on the base, into which liquid can be injected to determine the levelness of the base. BRIEF DESCRIPTION OF THE DRAWINGS
