Description

Technical Field

[0001] The utility model relates to the technical field of bases, and more specifically to a jack base. Background Art

[0002] The bottom is a mechanical part installed under an object or a device and plays a fixing role. A jack is a light and small lifting device that uses a rigid lifting piece as a working device to lift heavy objects through a small stroke of the top support or bottom claws, and the jack base is installed at the lower end of the jack and fixedly supports it.

[0003] At present, when a vehicle breaks down and a jack is needed for lifting support and inspection, if the ground where the vehicle breaks down is hard, such as cement and asphalt roads, the base maintains planar contact and support with the hard ground, and if the ground where the vehicle breaks down is soft, such as soft soil roads, during the process of the base maintaining planar contact with the soft ground, some areas of the base are prone to collapse and drop due to excessive pressure squeezing the soft ground, resulting in an uneven ground and a small sliding phenomenon at the bottom, making the support of the base unstable, thereby affecting the use of the jack. Therefore, there is an urgent need to improve the technology of the jack base structure to improve this equipment.

[0004] Therefore, the utility model proposes a jack base. Utility Model Content

[0027] During use of the present invention, the round rod 4 is lifted to drive the jack body 2 to be moved to the vicinity of the automobile lifting support point, and then the connecting plate 3 is toggled to drive the round rod 4 to flip along the right direction for storage, and the bottom frame 1 is pushed to drive the jack body 2 to move toward the automobile lifting support point, so that the jack body 2 is in contact with the automobile lifting support point, so that the jack body 2 can lift the automobile. During the lifting operation, if the ground is hard, the support seat 5 is directly in contact with the ground for stable support. If the ground is soft, the operator can operate the jack body 2. The rocker wheel 9 drives the rotating rod 10 to rotate, so that the meshing transmission action of the second bevel gear 803 and the first bevel gear 802 in the lifting mechanism 8 drives the threaded rod 801 to rotate, and the rotation of the threaded rod 801 drives the moving nut 804 to move downward, so that it drives a pair of L-shaped plates 805 to move downward, prompting the moving plate 6 and the gripping cone 7 to move downward, penetrate into the soft ground, maintain firm contact with it, and are not prone to small movements, and the auxiliary support seat 5 provides stable support, thereby ensuring the stable operation of the jack body 2 and enhancing the use effect.

[0028] See also Figure 3-4 The lifting mechanism 8 includes a threaded rod 801 rotatably connected between the inner walls of the bottom frame 1, the outer end of the threaded rod 801 is sleeved with a first bevel gear 802, and the outer end of the first bevel gear 802 is meshedly connected with a second bevel gear 803, the left end of the second bevel gear 803 is fixedly connected to the right end of the rotating rod 10, the outer end of the threaded rod 801 is threadedly connected with a moving nut 804, and the front and rear ends of the moving nut 804 are fixedly connected with an L-shaped plate 805, a pair of through openings 806 are opened at the inner bottom end of the bottom frame 1, and the lower end of the L-shaped plate 805 passes through the through opening 806 and is fixedly connected to the upper end of the moving plate 6.

[0029] During use of this solution, if the ground is hard, the support seat 5 directly contacts the ground for stable support. If the ground is soft, the hand-cranked wheel 9 is operated to drive the rotating rod 10 to rotate, so that it drives the second bevel gear 803 to rotate. The second bevel gear 803 drives the first bevel gear 802 to rotate through the meshing transmission action, so that it drives the threaded rod 801 to rotate, prompting the movable nut 804 to move downward under the rotation of the threaded rod 801, and drives a pair of L-shaped plates 805 to move downward, so that the movable plate 6 and the gripping cone 7 move downward, penetrate into the soft ground, maintain firm contact with it, and are not prone to small movements. The auxiliary support seat 5 provides stable support, thereby ensuring the stable operation of the jack body 2 and enhancing the use effect.
