Description

Technical Field

[0001] This utility model relates to the field of jack technology, and in particular to a sand jack. Background Technology

[0002] In vehicle repair, rescue and other scenarios, jacks are a commonly used lifting tool that uses hydraulic or mechanical principles to support and lift heavy objects.

[0003] Because sandy terrain is unstable, it can suddenly loosen under external forces or its own weight, causing the jack base to shift. Traditional jacks lack adaptive adjustment structures, making it difficult to maintain a vertical lifting position. This can easily lead to safety accidents due to tilting, or even damage to the vehicle being lifted. Furthermore, for excessively soft sandy ground, ordinary jacks lack additional auxiliary support structures to further distribute pressure, making it difficult to meet the requirements for stable lifting. To overcome these disadvantages, this utility model provides a sand jack. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sand jack.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sand jack, comprising a base, a sliding chamber inside the base, a sliding opening at the top of the base, a sliding plate fixedly connected to the sliding chamber and below the sliding opening, a first rotating seat fixedly connected to the top of the sliding plate, a first rotating block rotatably connected to the first rotating seat, a jack body disposed on one side of the first rotating block, an offset component disposed on the inner wall of the sliding chamber, moving components disposed on both sides of the base, and an auxiliary support component disposed at the top of the base.

[0006] Furthermore, the offset assembly includes a slide rail formed in the inner wall of the sliding chamber, a slider slidably connected to the slide rail, a plurality of limiting telescopic rods fixedly connected to one side of the slider, one end of the limiting telescopic rods fixedly connected to one side of the sliding plate, and a first spring fixedly connected to one side of the slider and around the limiting telescopic rods, one end of the first spring fixedly connected to one side of the sliding plate.

[0007] Furthermore, the movable component includes movable chambers fixedly connected to both sides of the base, a second spring fixedly connected inside the movable chamber, and a universal wheel slidably connected inside the movable chamber, with one end of the second spring fixedly connected to one side of the universal wheel.

[0008] Furthermore, the auxiliary support assembly includes a connecting rod disposed at the top of the base, with a second rotating seat fixedly connected to both ends of the connecting rod, a second rotating block rotatably connected to the second rotating seat, a supporting circular plate fixedly connected to one side of the second rotating block, and a fixing assembly disposed at the top of the base and on both sides of the connecting rod.

[0009] Furthermore, the fixing assembly includes a plurality of first fixing plates at the top of the base and located on both sides of the connecting rod, with a first fixing hole on one side of each first fixing plate, and a plurality of second fixing plates on both sides of the connecting rod, with a second fixing hole on one side of each second fixing plate.

[0010] Furthermore, both the second fixing hole and the first fixing hole are provided with internal threads, and fixing bolts are threadedly connected to the second fixing hole and the first fixing hole.

[0011] The beneficial effects of this utility model are:

[0012] In use, this utility model utilizes the rotational cooperation between the first rotating seat and the first rotating block, along with the sliding action of the sliding plate in the sliding chamber of the offset component. When the sand suddenly loosens, causing the base to shift, the jack body can adaptively adjust its posture through the coordinated action of the aforementioned structures, always maintaining a vertical state. This avoids affecting the lifting effect or causing safety hazards due to tilting, thereby improving the reliability of use in unstable sandy environments. By setting auxiliary support components, when facing excessively soft mud and sand, the contact area with the ground can be increased through the support circular plate. Combined with the fixing action of the fixing components, the pressure of the jack on the ground can be effectively dispersed, preventing the base from sinking into the mud and sand, further improving the stability and load-bearing capacity of the device in soft sandy environments.

[0022] As shown in the figure, the offset assembly includes a slide rail 8 opened on the inner wall of the sliding chamber 2, a slider 9 slidably connected on the slide rail 8, a number of limiting telescopic rods 10 fixedly connected to one side of the slider 9, one end of the limiting telescopic rod 10 fixedly connected to one side of the sliding plate 4, and a first spring 11 fixedly connected to one side of the slider 9 and around the limiting telescopic rods 10, one end of the first spring 11 fixedly connected to one side of the sliding plate 4, to prevent the jack body 23 from shifting due to loosening of mud and sand.

[0023] As shown in the figure, the movable component includes movable chambers 12 that are fixedly connected to both sides of the base 1. A second spring 13 is fixedly connected inside the movable chamber 12, and a universal wheel 14 is slidably connected inside the movable chamber 12. One end of the second spring 13 is fixedly connected to one side of the universal wheel 14 for moving the device.

[0024] As shown in the figure, the auxiliary support assembly includes a connecting rod 15 set at the top of the base 1. A second rotating seat 20 is fixedly connected to both ends of the connecting rod 15. A second rotating block 21 is rotatably connected to the second rotating seat 20. A support circular plate 22 is fixedly connected to one side of the second rotating block 21. A fixing assembly is set at the top of the base 1 and on both sides of the connecting rod 15 to increase the contact area between the device and the ground when facing soft mud and sand.

[0025] As shown in the figure, the fixing assembly includes several first fixing plates 16 at the top of the base 1 and located on both sides of the connecting rod 15. A first fixing hole 17 is provided on one side of the first fixing plate 16, and several second fixing plates 18 are provided on both sides of the connecting rod 15. A second fixing hole 19 is provided on one side of the second fixing plate 18 for fixing the connecting rod 15 to the base 1.

[0026] As shown in the figure, both the second fixing hole 19 and the first fixing hole 17 are provided with internal threads. Fixing bolts 24 are threadedly connected to the second fixing hole 19 and the first fixing hole 17, which are used to connect the second fixing hole 19 and the first fixing hole 17.

[0027] Working Principle: During use, first check the entire device for damage. After inspection, move the device to the bottom of the vehicle for support using the casters 14 on the moving chamber 12. Once in position, the jack body 23 adjusts its angle initially through the rotational connection between the first rotating block 6 and the first rotating seat 5 to meet lifting requirements. Then, the jack body 23 lifts the vehicle. During lifting, the pressure exerted by the vehicle on the device compresses the second spring 13 in the moving chamber 12, causing the casters 14 to enter the moving chamber 12, bringing the base 1 into contact with the ground. This increases the contact area between the device and the ground and protects the casters 14 from damage due to excessive pressure during lifting. When the sand suddenly loosens, causing the base 1 to shift, the sliding plate 4 inside the sliding chamber 2 slides within the sliding chamber 2 along with the shift of the base 1, simultaneously driving the slider 9 to move synchronously along the slide rail 8. The limiting telescopic rod 10 extends and retracts accordingly to limit... To control the sliding direction, the first spring 11 generates a reverse force through elastic deformation, buffering the impact of the offset. During this process, the first rotating block 6 rotates on the first rotating seat 5 to cooperate with the sliding plate 4, enabling the jack body 23 to adaptively adjust its posture and always maintain a vertical state, ensuring a stable and safe lifting process. If facing overly soft mud and sand, first place the connecting rod 15 on the base 1, then align the second fixing plates 18 on both sides of the connecting rod 15 with the first fixing plate 16 at the top of the base 1, and screw the fixing bolts 24 into the corresponding second fixing holes 19 and first fixing holes 17 to complete the fixing of the support circular plate 22. Then rotate the second rotating block 21 to make the support circular plate 22 contact the ground. The unfolded support circular plate 22 increases the contact area with the ground, effectively dispersing the overall pressure of the device on the ground, preventing the base 1 from sinking into the mud and sand, and further improving the support stability of the device in soft sandy environments, thereby ensuring the smooth progress of the lifting operation.
