Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical lifting equipment, and more specifically, it relates to a portable horizontal jack. Background Technology

[0002] A portable horizontal jack is a hydraulic tool commonly used in vehicle repair, heavy object handling, and other similar applications. It features a low profile and high load-bearing capacity, effectively lifting and supporting heavy objects. To use it, push the lifting lever (handle) up and down, which in turn drives the oil pump to generate pressure, thereby raising the piston in the cylinder and lifting the object.

[0003] Based on the above, the inventors have discovered the following problems: In the use of existing convenient horizontal jacks, most devices require people to use their hands to push the handle up and down, which consumes a lot of physical strength, causing inconvenience and reducing the efficiency of the jack in lifting heavy objects. At the same time, the jack is prone to deviation during the up and down operation of pushing the handle, which increases the danger during the operation.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a portable horizontal jack, in order to achieve a more practical value. Utility Model Content

[0005] The purpose and function of this portable horizontal jack are achieved by the following specific technical means:

[0006] A portable horizontal jack includes a jack body, mounting bases on mounting plates on both sides of the jack body, a T-shaped groove on the inner side of each mounting base, a slide seat movably mounted in the T-shaped groove, a pressure plate installed between the slide seats in a pair of T-shaped grooves, a handle at one end of the jack body, the pressure plate being located above the handle, a support assembly mounted at the bottom of the mounting base, and a carrying handle assembly mounted on the mounting plates on both sides of the jack body.

[0007] Furthermore, a limiting post is installed inside the T-shaped slide groove. The limiting post passes through the slide block and is slidably connected to it. A spring is installed inside the T-shaped slide groove. The spring is fitted around the limiting post, and the top end of the spring is connected to the bottom end of the slide block.

[0008] Furthermore, the bottom end of the pressure plate is provided with an arc-shaped groove, and the pressure plate fits against the handle through the arc-shaped groove, with a distance of 5cm between the pressure plate and the handle.

[0009] Furthermore, the support assembly includes a pair of mounting bases with threaded rods mounted at their bottom ends, and the bottom ends of the threaded rods are threadedly connected to threaded sleeves.

[0010] Furthermore, the carrying assembly includes a pair of rotating rods, the bottom ends of which are rotatably connected to mounting plates on both sides of the jack body via hinges, and a sleeve rod is movably mounted on the top end of each rotating rod, with a handrail installed between the top ends of the pair of sleeve rods.

[0011] Furthermore, the sleeve rod is slidably connected to the rotating rod via a slide rail, and a locking bolt is installed on one side of the sleeve rod, with one end of the locking bolt threadedly connected to one side of the rotating rod.

[0012] Furthermore, a brake caster is installed on one bottom end of the mounting plates on both sides of the jack body, and a roller is installed on the other bottom end of the mounting plates on both sides of the jack body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By stepping on the pressure plate and pressing it down, the pressure plate contacts the handle. Pressing the handle down then applies pressure to the oil pump that drives the jack, thereby lifting the piston in the cylinder. The lifting platform on the jack lifts the load, eliminating the need for manual operation of the handle, effectively saving energy and improving the efficiency of lifting heavy objects.

[0015] The sliding block is connected to the limiting post, allowing the pressure plate to move up and down along the path of the limiting post. The spring force resets the sliding block, causing the pressure plate to rise again. At this point, repeatedly stepping on the pressure plate allows the handle to be operated up and down, improving practicality.

[0016] By rotating the threaded sleeve, it moves downward along the threaded rod until it contacts the ground, thus keeping the jack body stable during the lifting of heavy objects. Rotating the locking bolt connects one end of it to the threaded side of the rotating rod, keeping the sleeve and rotating rod stable. People can hold the handrail while operating the lifting mechanism, improving safety. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 3 As shown:

[0027] This utility model provides a portable horizontal jack, including a jack body 1. Mounting seats 2 are mounted on mounting plates on both sides of the jack body 1. Each mounting seat 2 has a T-shaped groove 3 on its inner side, and a sliding block 4 is movably mounted within the T-shaped groove 3. A pressure plate 5 is installed between a pair of sliding blocks 4 within the T-shaped groove 3. A handle 15 is provided at one end of the jack body 1. The pressure plate 5 is located above the handle 15. A support component is mounted at the bottom of the mounting seat 2. Hand-carrying components are mounted on the mounting plates on both sides of the jack body 1. In use, the user steps on the pressure plate 5 and presses it down. The pressure plate 5 contacts the handle 15, pressing down on the handle 15. The handle 15 exerts pressure on the oil pump that drives the jack body 1, thereby lifting the piston in the oil cylinder. The lifting platform on the jack body 1 raises the heavy object, avoiding the traditional method of manually operating the handle 15, effectively saving physical strength and improving the efficiency of lifting heavy objects.

[0028] The T-shaped slide groove 3 is equipped with a limiting post 7, which passes through the slide block 4 and is slidably connected to it. A spring 8 is installed in the T-shaped slide groove 3, and the spring 8 is fitted around the limiting post 7. The top end of the spring 8 is connected to the bottom end of the slide block 4. Through the slidable connection between the slide block 4 and the limiting post 7, the pressure plate 5 moves up and down along the path of the limiting post 7. The elastic force of the spring 8 resets the slide block 4, causing the pressure plate 5 to rise again. At this time, repeatedly stepping on the pressure plate 5 can operate the handle 15 up and down, which improves practicality.

[0029] The bottom end of the pressure plate 5 is provided with an arc-shaped groove 6. The pressure plate 5 fits against the handle 15 through the arc-shaped groove 6. The distance between the pressure plate 5 and the handle 15 is 5cm. When the jack body 1 returns to its initial state, one end of the handle 15 tilts upwards. The distance between the pressure plate 5 and the handle 15 is 5cm, which makes it easy for the handle 15 to return to its initial position.

[0030] The support assembly includes a pair of mounting bases 2 with threaded rods 9 installed at their bottom ends. The bottom ends of the threaded rods 9 are threadedly connected to threaded sleeves 10. By rotating the threaded sleeves 10, the threaded sleeves 10 move downwards along the threaded rods 9, making them contact the ground. This keeps the jack body 1 stable during the lifting of heavy objects, improving safety in use.

[0031] The handle assembly includes a pair of rotating rods 11. The bottom ends of the pair of rotating rods 11 are rotatably connected to the mounting plates on both sides of the jack body 1 via hinges. A sleeve rod 12 is movably installed at the top of each rotating rod 11, and a handle 13 is installed between the top ends of the pair of sleeve rods 12.

[0032] The sleeve rod 12 is slidably connected to the rotating rod 11 via a slide rail. A locking bolt 14 is installed on one side of the sleeve rod 12. One end of the locking bolt 14 is threadedly connected to one side of the rotating rod 11. Rotating the locking bolt 14 makes one end of it threadedly connected to one side of the rotating rod 11, keeping the sleeve rod 12 and the rotating rod 11 stable. When people operate the lifting of heavy objects, they can hold the handrail 13 with their hands, which improves the stability of use.

[0033] Among them, a brake caster 16 is installed on one side of the bottom end of the mounting plates on both sides of the jack body 1, which facilitates the jack body 1 to turn and move in various directions. A roller 17 is installed on the other side of the bottom end of the mounting plates on both sides of the jack body 1, which facilitates the movement of the jack body 1.

[0034] The specific usage and function of this embodiment are as follows:

[0035] First, check the integrity of the device. Only use it after confirming it is intact. When using it, first move the jack body 1 to the bottom of the load using the rollers 17 and brake casters 16. Rotate the threaded sleeve 10; the threaded sleeve 10 moves downwards along the threaded rod 9 until it contacts the ground, ensuring the jack body 1 remains stable during lifting. Rotate the locking bolt 14 so that one end is threadedly connected to one side of the rotating rod 11. The sleeve rod 12 remains stable with the rotating rod 11. Hold the handle 13 and step on the pressure plate 5, pressing it downwards. The pressure plate 5 contacts the handle 15, causing it to move downwards. Pressing the handle 15 generates pressure on the oil pump that drives the jack body 1, thereby lifting the piston in the oil cylinder. The lifting platform on the jack body 1 raises the load. The slide 4 is slidably connected to the limit post 7, causing the pressure plate 5 to move up and down along the path of the limit post 7. The spring force of the spring 8 resets the slide 4, causing the pressure plate 5 to rise again. At this time, repeatedly stepping on the pressure plate 5 can operate the handle 15 up and down, avoiding the traditional method of operating the handle 15 up and down by hand, effectively saving physical strength and improving the efficiency of lifting loads. This device has a novel overall design and simple structure, and is therefore worthy of widespread promotion and use.
