Description

Technical Field

[0001] This utility model relates to the field of foot-operated jack technology, specifically a foot-operated driven jack. Background Technology

[0002] A foot-operated jack is a mechanical device that uses foot pedals to provide power and lift heavy objects.

[0003] A foot-operated jack converts human power into mechanical or hydraulic energy through a foot pedal mechanism, driving the lifting components to rise. The hydraulic system achieves lifting and lowering by compressing and releasing hydraulic oil, while the mechanical transmission system transmits and amplifies force through structures such as gears, chains, or levers.

[0004] Currently, when using a foot-operated jack to lift an object, the jack is placed below the object, and mechanical transmission controls the jack body to lift the object. However, when lifting the object as a whole, multiple jack bodies are needed. To prevent one side from being lifted too high, causing the object to tilt and posing a safety hazard, multiple jack bodies need to be manually controlled to lift and stably support the object. However, this requires a high level of skill in controlling the jack bodies and poses certain safety risks. Therefore, we propose a foot-operated jack to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a foot-operated driven jack, which solves the problem that when lifting an object as a whole, multiple jacks are needed to lift the object. In order to avoid lifting one side too high and causing the object to tilt, which poses a potential installation hazard, multiple jacks need to be manually controlled to lift the object stably and support it. However, this requires a high level of manual control of the jacks and poses certain safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foot-operated driven jack, comprising a jack structure, with connecting units between the jack structures for adjusting the spacing between adjacent jack structures. Each jack structure provides support to multiple locations simultaneously. An adjustment unit is provided on one side of each jack structure for adjusting its position, moving it to a designated location for support. The jack structure includes a jack body and a linkage system. The linkage system is driven onto the jack body, and a telescopic frame is mounted on the linkage system. The telescopic frame controls the transmission of multiple linkage systems, cooperating with the jack body to achieve a lifting function. Connecting holes are provided on both sides of the telescopic frame, through which mounting seats are installed. The mounting seats facilitate the transmission of the telescopic frame.

[0007] Preferably, a lifting head is fixedly installed on the piston of the jack body, and the lifting head is used to support the object.

[0008] Preferably, the connecting unit includes a first connecting rod and a second connecting rod, one side of the first connecting rod and the second connecting rod are respectively disposed with a corresponding jack structure, and the first connecting rod and the second connecting rod are slidably connected.

[0009] Preferably, a fixing member is provided between the first connecting rod and the second connecting rod, the fixing member being used to fix the first connecting rod and the second connecting rod.

[0010] Preferably, the adjustment unit includes a fixed base, which is fixedly connected to the bottom of the jack structure. An electric telescopic rod is installed on one side of the fixed base, and the electric telescopic rod is used to adjust the movement of the jack structure under the object.

[0011] Preferably, a first support wheel is installed at the end of the electric telescopic pole away from the electric telescopic pole, and the first support wheel facilitates the movement of the electric telescopic pole.

[0012] Preferably, a second support wheel is installed on one side of the jack body, which facilitates the movement of the jack structure under the object.

[0013] This utility model discloses a foot-operated driven jack, which has the following beneficial effects:

[0014] This foot-operated jack moves relative to the first and second connecting rods by pulling them. At this time, the distance between the two jack structures is adjusted by the sliding of the first and second connecting rods, so that the jack structures are in the right position. Adjusting multiple jack structures to the right position allows multiple jack structures to lift the object and ensures the stability of the object being lifted.

[0015] By adjusting the jack structure to a designated support point, multiple jacks can be used to lift the object, thus supporting it. This avoids the need for multiple jacks to lift an object when multiple points of support are required, as this would require manual adjustment of the jack structure multiple times. Furthermore, lifting one side at a time could cause tilting and pose installation risks. Lifting the object simultaneously with multiple jacks ensures stability during the lifting process.

[0022] This application embodiment provides a foot-operated jack, which solves the problem that when lifting an object as a whole, multiple jack bodies 11 are needed to lift the object. In order to avoid lifting one side too high and causing the object to tilt, which poses a hidden danger to the installation, multiple jack bodies 11 need to be manually controlled to lift the object stably and support it. However, this requires a high degree of manual control of the jack bodies 11 and poses certain safety hazards. The embodiment achieves this by pulling the first connecting rod 21 and the second connecting rod 22 to move relative to each other. At this time, the distance between the two jack structures 1 is adjusted by the sliding of the first connecting rod 21 and the second connecting rod 22, and the multiple jack structures 1 are adjusted to a suitable position so that the multiple jack structures 1 can lift the object and ensure the stability of the object lifting.

[0023] By adjusting the jack structure 1 to the designated support point, multiple jack structures 1 can achieve the lifting function and support the object. This avoids the need for multiple jack structures 1 to lift the object when multiple points of support are required, and avoids the need for manual adjustment of the jack structure 1 multiple times. Furthermore, lifting one side may cause the other side to tilt, posing a potential installation hazard. Lifting the object simultaneously with multiple jack structures 1 ensures the stability of the object's lifting.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
