Description

Technical Field

[0001] This utility model relates to the field of jacks, and in particular to a side-rocking jack stabilizing support. Background Technology

[0002] Side-crank jacks, as common vehicle-mounted tools and small lifting devices, are widely used in automotive repair, equipment installation, and other scenarios. Their working principle involves side-cranking a handle to drive internal gears or a hydraulic mechanism, enabling the vertical lifting of heavy objects. However, in practical use, especially in field rescue or non-standard workshop environments, the stability of side-crank jacks faces significant challenges. In existing technologies, side-crank jacks are typically equipped with a simple fixed base or support pad, whose main function is merely to increase the basic contact area.

[0003] However, traditional jacks are mostly flat at the bottom, which cannot effectively adapt to uneven or soft ground. They are prone to point or line contact, resulting in unstable support and a huge risk of tipping over. Secondly, even on flat ground, the anti-slip performance of fixed bases is very limited. During the lifting process, if the vehicle is subjected to lateral force (such as when removing tires), the jack is very likely to slip as a whole, posing a serious threat to the operator's personal safety.

[0004] Therefore, a side-rocking jack stable support was designed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a stable support for a side-cranked jack. It solves the problems of traditional side-cranked jack supports having flat bottom surfaces, making them unsuitable for uneven or soft ground, easily leading to point-line contact and overturning. Even on flat ground, their anti-slip performance is insufficient, and they are prone to sliding under lateral forces, posing a significant safety hazard.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A side-crank jack stabilizing support includes a support plate, a support frame disposed at the bottom of the support plate to improve overall stability, and a stabilizing net installed at the bottom of the support frame to increase the contact area and friction with the ground. The support plate has a plurality of diagonally distributed circular holes.

[0007] Preferably, at least three sets of connecting rings arranged in a circular array are fixedly provided at the edge of the stabilizing net, and the connecting rings are used to fix the stabilizing net and the support frame.

[0008] Preferably, a through hole is provided at the center of the stabilizing mesh, and multiple protrusions are fixedly installed at the mesh connection points of the stabilizing mesh.

[0009] Preferably, the outer walls of the plurality of protrusions are covered with a rubber layer to increase the friction with the ground.

[0010] Preferably, multiple support frames are provided and arranged in a circumferential array, and a mounting plate is provided on the top of each support frame, the mounting plate being hinged to the top of the multiple support frames.

[0011] Preferably, a connecting frame is hinged to the rod of the plurality of support frames, and the ends of the plurality of connecting frames away from the support frames are hinged together to a movable ring, and a threaded rod is threadedly connected to the center of the movable ring.

[0012] Preferably, the bottom end of the support frame is fixedly provided with two symmetrical hooks, which are made of steel wire that can be bent manually.

[0013] Preferably, the connecting ring can be hooked onto the hook, and the hook can be manually bent to close it, thereby fixing the connecting ring to the hook.

[0014] Preferably, the bottom of the threaded rod and the multiple support frames are all constructed in a conical shape to facilitate insertion into the ground; a first bevel gear is fixedly provided at the top of the threaded rod, the first bevel gear is rotatably connected to the support plate, a second bevel gear is meshed on the side of the first bevel gear, and a limiting block is rotatably sleeved on the central shaft of the second bevel gear.

[0015] Preferably, the top of the limiting block is fixedly connected to the support plate, and a rotating wheel is fixedly provided at one end of the central shaft of the second bevel gear.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses a bevel gear-driven deployable support frame, which allows its bottom to actively penetrate the ground, providing a rigid anchoring effect against lateral forces; at the same time, it utilizes a quick-attachable stabilizing net, along with protrusions on its surface, to greatly increase the ground contact area and static friction; thus combining active anchoring with anti-slip, it effectively solves the problem that existing supports are prone to sinking, sliding, or even overturning on soft or sloping ground. When not in use, the entire support can be folded up for easy carrying and storage; when in use, it can be quickly unfolded to adapt to various complex working conditions, from hard flat ground to soft mud, effectively overcoming the problem of existing fixed supports being bulky and having limited support area.

[0024] Please see Figure 1-5 A side-rocking jack stabilizing support includes a support plate 1, a support frame 2 installed at the bottom of the support plate 1 to improve the overall stability, and a stabilizing net 3 installed at the bottom of the support frame 2 to increase the contact area and friction with the ground. The support plate 1 has a plurality of diagonally distributed circular holes 11. At least three sets of connecting rings 31 arranged in a circular array are fixedly provided at the edge of the stabilizing net 3. The connecting rings 31 are used to fix the stabilizing net 3 and the support frame 2. A through hole 32 is opened at the center of the stabilizing net 3. Multiple protrusions 33 are fixedly installed at the mesh connection points of the stabilizing net 3. The outer walls of multiple protrusions 33 are covered with a rubber layer to increase the friction with the ground. Multiple support frames 2 are arranged in a circumferential array. A mounting plate 21 is provided on the top of the support frame 2. The mounting plate 21 is hinged to the top of multiple support frames 2. A connecting frame 22 is hinged to the rod of multiple support frames 2. The ends of multiple connecting frames 22 away from the support frame 2 are hinged to a moving ring 23. A threaded rod 4 is threadedly connected to the center of the moving ring 23. Two symmetrical hooks 24 are fixedly provided at the bottom of the support frame 2. The hooks 24 are made of steel wire that can be bent manually. The connecting ring 31 can be hooked onto the hook 24, and the hook 24 can be manually bent to close it, thereby fixing the connecting ring 31 and the hook 24. The bottom of the threaded rod 4 and the multiple support frames 2 are all constructed in a conical shape to facilitate insertion into the ground. A first bevel gear 41 is fixedly installed on the top of the threaded rod 4. The first bevel gear 41 is rotatably connected to the support plate 1. A second bevel gear 42 is meshed on the side of the first bevel gear 41. A limiting block 43 is rotatably sleeved on the central shaft of the second bevel gear 42. The top of the limiting block 43 is fixedly connected to the support plate 1. A rotating wheel 44 is fixedly installed at one end of the central shaft of the second bevel gear 42.

[0025] In use, first, the stabilizing net 3 is attached to the hook 24 via the connecting ring 31. Then, the opening of the hook 24 is manually bent upward to make it more secure. Next, the rotating wheel 44 drives the threaded rod 4 to rotate through the second bevel gear 42 and the first bevel gear 41, forcing the moving ring 23 to descend. This causes the lower end of the circumferential array support frame 2 to be pushed outward through the connecting frame 22 until the conical structure at its bottom is inserted into the ground to achieve initial anchoring. The stabilizing net 3 then opens and lies flat under the unfolded support frame 2, forming a composite stable structure with the support plate 1 as the top bearing surface, the support frame 2 as the rigid support, and the stabilizing net 3 as the large-area anti-slip base.
