Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
As shown in Figure 1 to Figure 2, the transmission device of back starting target of the invention, including two groups of target rod sets 1, connecting rod 2, crank 3,
Motor 4, pedestal 5,6, two groups of rocking bar, 7, two groups of spring, 8, two groups of spring catch, 10, two groups of bearing needle bearing 11,12 and of main shaft
Two groups of spring bases 13, the left end of pedestal and right end are provided with spring housing 9, and two groups of springs are separately mounted to two groups of spring housings
Interior, motor is fixedly mounted on the base, and one end of crank is fixedly connected with the output end of motor, and the other end of crank passes through
Wherein one end of one group of needle bearing and connecting rod is rotatably connected, and connecting rod passes through another set needle bearing far from one end of crank
It being rotatably connected with one end of rocking bar, two groups of bearings are separately mounted to left end and the right end of pedestal, and two groups of bearings are oppositely arranged, and
And two groups of bearings and two groups of springs are respectively positioned on same straight line, the left end of main shaft sequentially passes through one group of bearing, one group of spring and one
Group spring base is simultaneously fixedly connected with the right end of one group of target rod set, and the right end of main shaft sequentially passes through another group of bearing, another group of spring
With another group of spring base and be fixedly connected with the left end of another group of target rod set, the one end of rocking bar far from connecting rod and main shaft is fixed connects
Connect, one end of two groups of springs passes through two groups of spring catch respectively and is fixedly connected with the left end of pedestal and right end, two groups of springs it is another
End is fixedly connected with two groups of spring bases respectively, and clamping screw is provided on two groups of spring bases, and two groups of spring bases pass through two groups of locks
Tight bolt is fixedly connected with main shaft；Spring can automatically adjust to required torque, alleviate to electricity in the process of movement
The requirement of motivation power, without counterweight is added again, mechanical structure is integrally simple, lighter in weight, easy to carry, while can be with several times
The number in current, charging is primary, and what bringing onto load worked normally acts number up to 1200 times or more, and work efficiency is high,
Power saving, and at work according to the difference for acting state, spring has different operating effect, has in the state of rising and increases torque
Effect in state there is buffer function to can effectively protect the impact failure of mechanical structure while power-assisted, greatly increase
The service life of transmission device.
The transmission device of back starting target of the invention, two groups of springs it is oppositely oriented；Through two groups of springs in main axis
Collective effect assists target body during rising, improves practicability.
The length of the transmission device of back starting target of the invention, crank, connecting rod and rocking bar is processed in required ratio；Guarantee is shaken
Angle needed for bar drives main axis, allows two groups of target rod sets that target body to be driven to carry out down, improves practicability.
The transmission device of back starting target of the invention drives the end of crank to rotate by motor at work, will be electric
The torque of motivation is transmitted to crank, and crank is moved in a circle by one end that connecting rod drives rocking bar to connect with connecting rod, rocking bar and master
The angle that one end of axis connection drives main axis certain, main shaft drive target body to rise, pass through two groups of bullets by two groups of target rod sets
The torque that spring generates reduces the torque of motor, reaches the purpose of balance power saving with this, according to acting state not in work
Together, spring has different operating effect, has increase torque playing state, has buffer function in state, helping
While power, it is can effectively protect the impact failure of mechanical structure, considerably increases the service life of transmission device, passes through two groups of bullets
Spring collective effect in main axis assists target body during rising, spring is realized during motion of main shaft
Reinforcement and subtract power, it is ensured that mechanism output torque it is constant, according to varying in weight for target body, rotation spring seat is realized to spring force
Adjusting, then tighten lock bolt so that spring base is fixed together with main shaft, so that spring base is then to spring by spring positioning
Play a part of fixed and adjusts.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications, these improvements and modifications can also be made
Also it should be regarded as protection scope of the present invention.
