Description

Technical Field

[0001] The utility model belongs to the technical field of jacks, and particularly relates to a jack which is easy to move. Background Art

[0002] Jack is a common lifting equipment. It is easy to operate, occupies a small area and is easy to transport. Therefore, it is widely used. Ordinary hydraulic jacks are small in size but heavy, and it is difficult to move them frequently.

[0003] The Chinese utility model patent currently announced as CN206088893U discloses a jack, which is provided with a hydraulic cylinder and a support base. The support base is arranged below the hydraulic cylinder. The support base includes a support plate and a plurality of support feet arranged below the support plate. The above arrangement solves the problem that the jack is prone to damage due to the unadjustable force direction when working at an uneven site. At the same time, the utility model has a simple structure, is easy to operate, and improves work efficiency.

[0004] Although this patent has the advantage of being able to adjust the height of the supporting legs so that the jack can remain level when working in an uneven field, its mobility is low because it is only in contact with the ground through the supporting legs, making it inconvenient to carry. Utility Model Content

[0005] The utility model aims to provide a jack which is easy to move, and solves the problem that the traditional jack is in contact with the ground only through supporting legs, has low flexibility and is inconvenient to carry.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a jack that is easy to move, including a jack body, a moving mechanism is arranged on the jack body, an adjusting mechanism is arranged below the moving mechanism, and a grounding plate is arranged on the lower surface of the adjusting mechanism;

[0007] The moving mechanism includes a mounting plate, a mounting tube, a micro cylinder and a sliding wheel. The mounting plate is arranged on the jack body. There are four mounting plates and they are symmetrically arranged. The mounting tube is arranged inside the mounting plate by bolts. The micro cylinder is arranged inside the mounting tube. The sliding wheel is arranged on the output shaft of the micro cylinder. The sliding wheel is located inside the mounting tube.

[0008] By adopting the above technical solution, by setting the jack body, the moving mechanism, the adjusting mechanism and the grounding plate, when in use, first the moving mechanism is fixed on the side wall of the jack, when the jack body needs to be moved, the moving mechanism can pass through the grounding plate to contact the ground, so that the moving mechanism drives the jack body to move, thereby increasing the mobility of the jack body, and then when the jack body is used on an uneven ground, the jack body can be leveled through the adjusting mechanism to avoid the need for the jack body to be tilted when used, and the force point of the jack body is designed to be in the middle The jack body will be damaged if it is tilted and used in an inclined manner, which shortens the service life of the jack body. In severe cases, the jack body will pop out and injure people. The moving mechanism includes a mounting plate, a mounting cylinder, a micro cylinder and a sliding wheel. When in use, the mounting cylinder is first fixedly installed by the mounting plate, and then the micro cylinder is arranged on the inner top of the mounting cylinder. When the jack body does not move, the micro cylinder drives the sliding wheel to shrink inside the mounting cylinder. When the jack body needs to move, the micro cylinder drives the sliding wheel to move downward, so that the sliding wheel contacts the ground, thereby increasing the maneuverability of the jack body.

[0009] The utility model is further configured as follows: the adjusting mechanism includes a first connecting plate, a second connecting plate, a moving block, a fixed plate, a screw rod and a handle; the first connecting plate is arranged on the lower surface of the mounting tube, the second connecting plate is arranged on the upper surface of the grounding plate, one end of the first connecting plate and one end of the second connecting plate are both rotatably connected, the moving block is arranged at the connection between the first connecting plate and the second connecting plate, the fixed plate is arranged on the upper surface of the grounding plate, the screw rod passes through the moving block and is rotatably arranged with the moving block thread, the handle is arranged at one end of the screw rod, and the other end of the screw rod is rotatably arranged on the surface of the fixed plate.

[0010] The above technical scheme is adopted, by setting a first connecting plate, a second connecting plate, a moving block, a fixed plate, a screw rod and a handle. When in use, the first connecting plate is first rotatably connected to the surface of the mounting tube, and the second connecting plate is rotatably connected to the upper surface of the grounding plate, and the connection points of the moving block, the first connecting plate and the second connecting plate are all rotatably connected to each other, and the fixed plate is fixedly set on the grounding plate. When the handle drives the screw rod to rotate, due to the threaded rotation connection between the moving block and the screw rod, the moving block can move on the screw rod, thereby changing the angle between the first connecting plate and the second connecting plate, thereby changing the height of the mounting tube, and then by changing the height of the four mounting tubes, the jack body can be leveled.

[0011] The utility model is further configured as follows: a horizontal plate is arranged on the side wall of the jack body, and a level is arranged on the horizontal plate.

[0012] By adopting the above technical solution, by setting a horizontal plate and a spirit level, when in use, first the horizontal plate is set on the jack body. After the jack body is leveled, the spirit level on the horizontal plate can be used to verify whether the jack body is level. This can avoid the need to tilt the jack body for use on uneven ground. The jack body is designed with the force point at the center. Tilted use often damages the jack body and shortens the service life of the jack body. In severe cases, the jack body may pop out and injure people.

[0013] The utility model is further configured as follows: a push handle is arranged on the jack body, and an anti-slip sleeve is arranged on the push handle.

[0014] By adopting the above technical solution, by providing a push handle and an anti-slip cover, when the jack body needs to move, the push handle can provide a fulcrum for the user, and the anti-slip cover can increase the friction between the user and the push handle, thereby preventing the user from slipping.

[0015] The utility model is further configured as follows: the grounding plate is made of rubber anti-skid material, a through hole is provided on the grounding plate, and the aperture of the through hole is larger than the diameter of the sliding wheel.

[0016] By adopting the above technical solution, a through hole is set. When in use, the diameter of the through hole is larger than the diameter of the sliding wheel. When the jack body needs to be moved, the micro cylinder can smoothly drive the sliding wheel to pass through the through hole and contact the ground.

[0017] The utility model is further configured as follows: a limit plate is arranged inside the installation cylinder, and the limit plate is arranged in cooperation with the sliding wheel.

[0018] By adopting the above technical solution, by setting a limit plate, when in use, the limit plate can limit the rise of the sliding wheel to prevent the sliding wheel from rising too high and contacting the inner wall of the installation tube, causing damage to the sliding wheel and the installation tube.

[0019] The utility model is further configured as follows: the first connecting plate and the second connecting plate are configured in a scissor shape.

[0020] By adopting the above technical solution and setting the connection shape of the first connecting plate and the second connecting plate, when the moving block moves on the screw rod, the angle between the first connecting plate and the second connecting plate can be better changed.

[0021] In summary, the utility model has the following beneficial effects:

[0022] By setting a mounting plate, a mounting tube, a micro cylinder and a sliding wheel, when in use, the mounting plate is first used to fix the mounting tube, and then the micro cylinder is set on the inner top of the mounting tube. When the jack body does not move, the micro cylinder drives the sliding wheel to shrink inside the mounting tube. When the jack body needs to move, the micro cylinder drives the sliding wheel to move downward so that the sliding wheel contacts the ground, thereby increasing the maneuverability of the jack body.

[0023] By setting a first connecting plate, a second connecting plate, a moving block, a fixed plate, a screw rod and a handle, when in use, the first connecting plate is first rotatably connected to the surface of the mounting tube, the second connecting plate is rotatably connected to the upper surface of the grounding plate, and the connecting parts of the moving block, the first connecting plate and the second connecting plate are all rotatably connected to each other, and the fixed plate is fixedly arranged on the grounding plate. When the handle drives the screw rod to rotate, due to the threaded rotation connection between the moving block and the screw rod, the moving block can move on the screw rod, thereby changing the angle between the first connecting plate and the second connecting plate, thereby changing the height of the mounting tube, and then by changing the height of the four mounting tubes, the jack body can be leveled.

[0024] Based on the above-mentioned improvements, the overall technical effect achieved by the present device is that the maneuverability of the jack body can be improved by adding sliding wheels, and then the jack body can be leveled so that the jack body can be used in different venues, thereby improving the safety of the jack body.

When the jack body 1 does not move, the micro cylinder 203 drives the sliding wheel 204 to shrink inside the mounting cylinder 202. When the jack body 1 needs to move, the micro cylinder 203 drives the sliding wheel 204 to move downward, so that the sliding wheel 204 contacts the ground, thereby increasing the mobility of the jack body 1.

[0045] Then, the first connecting plate 301 is rotatably connected to the surface of the mounting tube 202, the second connecting plate 302 is rotatably connected to the upper surface of the grounding plate 4, and the connection points of the moving block 303, the first connecting plate 301 and the second connecting plate 302 are all rotatably connected to each other, and the fixed plate 304 is fixedly arranged on the grounding plate 4. When the handle 306 drives the screw rod 305 to rotate, due to the threaded rotation connection between the moving block 303 and the screw rod 305, the moving block 303 can be moved on the screw rod 305, thereby changing the angle between the first connecting plate 301 and the second connecting plate 302, thereby changing the height of the mounting tube 202, and then by changing the height of the four mounting tubes 202, the jack body 1 can be leveled.

[0046] Then the horizontal plate 5 is set on the jack body 1. After the jack body 1 is leveled, the level meter 6 on the horizontal plate 5 can be used to verify whether the jack body 1 is level. This can avoid the jack body 1 from being tilted when used on an uneven ground. The force point of the jack body 1 is designed to be at the center. Tilt use often damages the jack body 1 and shortens the service life of the jack body 1. In severe cases, the jack body 1 will pop out and injure people.
