Problems solved by technology
During use, if the gap between the parts that need to be lifted or supported is small, it is difficult for ordinary jacks to achieve the role of lifting or supporting; if the top bracket or bottom claw of the jack design is relatively thin; although it can achieve lifting or Support parts with small gaps, but the top bracket or bottom claws are easily damaged; therefore, it is necessary to design a jack that can lift or support parts with small gaps and is stronger during use

specific Embodiment approach
[0060] The specific embodiment: when people use the jack designed by the present invention, put the first connecting plate 30 in the outer top 1 on the jack into the gap of the parts that need to be lifted or supported; turn the driving wheel 4; when the driving wheel 4 When rotating, the driving wheel 4 can drive the second rotating shaft 11 to rotate; because the first guide plate 33 installed on the first threaded wheel 29 and the corresponding two first drive plates 13 have the first drive of the first guide groove 34. The first guide groove 34 on the plate 13 cooperates; the first driving plate 13 having the first guide groove 34 is in a static state; so the rotation of the second rotating shaft 11 will make the two first threaded wheels 29 mounted thereon to generate move, and the moving direction is all towards the corresponding first drive block 27; the movement of the two first threaded wheels 29 will make the corresponding two first drive rods 28 swing and the angle b...

The invention belongs to the technical field of jacks, and particularly relates to a jack based on gear transmission. The jack comprises outer jack bodies, inner jack bodies, a mounting shell and driving gears. When people use the jack, first connecting plate in the outer jack bodies of the jack are placed into a gap of a part needing to be lifted or supported, the driving gears are rotated, whenthe driving gears rotate, the driving gears can enable corresponding first driving plates to move upwards, the first driving plates move upwards to drive the one, located on the upper side, of the twoouter jack bodies to move upwards, meanwhile, when the driving gears rotate, the driving gears enable threaded driving rings to drive the two inner jack bodies to move, when the inner jack bodies andthe outer jack bodies are completely matched, first gears rotate to enable the corresponding inner jack bodies to move upwards, and at the moment, the inner jack body and the outer jack body on the upper side can move upwards together to lift or support the part needing to be lifted or supported. According to the jack, parts with small gaps can be lifted or supported, and meanwhile, the firmnessof the jack is ensured.
Description
technical field [0001] The invention belongs to the technical field of jacks, in particular to a gear-driven jack. Background technique [0002] Jack is the simplest lifting equipment with a small lifting height. It uses a rigid jack as a working device, and is a light and small lifting equipment that lifts heavy objects in the stroke by a top bracket or a bottom claw. Divided into two kinds of mechanical type and hydraulic type, the jack is mainly used in factories, mines, transportation and other departments as vehicle repair and other lifting, support and other work. During use, if the gap between the parts that need to be lifted or supported is small, it is difficult for ordinary jacks to achieve the role of lifting or supporting; if the top bracket or bottom claw of the jack design is relatively thin; although it can achieve lifting or Supporting parts with small gaps, but the top bracket or bottom claws are easy to be damaged; so it is very necessary to design a jack ...
