DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 The utility model provides a technical solution: a reciprocating drive mechanism based on a motor, comprising: a bracket 1, a motor 2 is connected to the middle of the upper surface of the lower end of the bracket 1 by bolts, a pulley 3 is provided on the output end of the rear side of the motor 2, a reduction gear box 4 is connected to the upper surface of the left side of the motor 2 and located at the lower end of the bracket 1 by bolts, the input end of the front side of the reduction gear box 4 is also provided with a pulley 3, the outer sides of the two pulleys 3 are provided with belts, a toothed disc 5 is provided on the outer side of the output end in the middle of the left side of the reduction gear box 4, the front side of the upper surface of the lower end of the bracket 1 is connected to the transmission end bracket 6, the upper end of the transmission end bracket 6 is rotatably connected to a transmission rod 7, the outer side of the left end of the transmission rod 7 is also provided with a toothed disc 5, and the outer sides of the two toothed discs 5 are provided with chains The right end of the transmission rod 7 is sleeved with an eccentric wheel 8, and the inside of the eccentric wheel 8 is rotatably connected to the active rod 9, and the rear end of the active rod 9 is rotatably connected to the driven plate 10. The rear side of the upper surface of the lower end of the bracket 1 is connected to the output end bracket 11, and the right side of the upper surface of the output end bracket 11 is connected to the reciprocating limit cavity 12. The driven plate 10 is inserted into the inside of the reciprocating limit cavity 12, and the inside of the output end bracket 11 and the left side of the reciprocating limit cavity 12 are rotatably connected to a reciprocating rotating rod 13. The lower end of the output end bracket 11 is rotatably connected to a reciprocating output rod 14, and the reciprocating rotating rod 13 and the driven plate 10 are driven by gears, and the lower end of the reciprocating output rod 14 and the reciprocating rotating rod 13 are driven by helical gears.

[0026] When in use, after starting the motor 2, the output end of the motor 2 rotates, driving the pulley 3 to rotate, and the two pulleys 3 are transmitted through the belt, so that the input shaft at the front end of the reduction gear box 4 rotates. After the reduction gear box 4 reduces the speed and increases the torque, it drives the sprocket 5 at the output end to rotate, and the two sprockets 5 are transmitted through the chain, so that the transmission rod 7 at the upper end of the transmission end bracket 6 rotates. When the transmission rod 7 rotates, it drives the eccentric wheel 8 to rotate, and the active rod 9 rotates around the center of the eccentric wheel 8, and the end of the active rod 9 pulls the driven plate 10 to slide back and forth inside the reciprocating limit cavity 12. When the driven plate 10 slides back and forth, it drives the reciprocating rotating rod 13 to perform forward and reverse rotation through the teeth on the left side, and the lower end of the reciprocating rotating rod 13 is meshed with the reciprocating output rod 14 through a helical gear, driving the reciprocating output rod 14 to perform reciprocating forward and reverse rotation.

[0027] like Figure 1-4 As shown, the embodiment of the present invention provides an implementation method. Based on the above implementation method, the active rod 9, the driven plate 10 and the reciprocating limit cavity 12 are all made of carbon steel.

[0028] From the analysis of the above structure, it can be seen that the active rod 9, the driven plate 10 and the reciprocating limit cavity 12 are all made of carbon steel, which has high strength and hard texture, and can reduce friction loss.

[0029] like Figure 1-5 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the left surface of the transmission end bracket 6 is connected to the chain tensioning base 21 by bolts, and the internal lower end of the chain tensioning base 21 is rotatably connected to the chain bracket 1 22, and the lower end of the chain bracket 1 22 is rotatably connected to the chain bracket 2 23, and the lower end of the chain bracket 23 is rotatably connected to the small chain plate 24, and the small chain plate 24 is meshed with the chain, and a reset rod 25 is rotatably connected between the chain bracket 2 23 and the chain tensioning base 21, and the reset rod 25 is fixedly connected to the inside of the spring.

[0030] From the analysis of the above structure, it can be seen that the reset rod 25 will lift the chain bracket 2 23 and the chain bracket 1 22, and the small chain plate 24 will engage with the chain. When the chain becomes loose after long-term use, the reset rod 25 will support the chain bracket 2 23 and push the small chain plate 24 downward to tighten the chain.

[0031] like Figure 1-6As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a belt tensioning base 26 is connected to the middle of the upper surface of the lower end of the bracket 1, and the upper end of the belt tensioning base 26 is rotatably connected to the belt tensioning bracket 27. The rear side of the belt tensioning bracket 27 is rotatably connected to the belt tensioning pulley 28. The upper end of the belt tensioning pulley 28 is against the lower surface of the belt, and a reset rod 25 is also rotatably connected between the belt tensioning bracket 27 and the belt tensioning base 26.

[0032] From the analysis of the above structure, it can be seen that the reset rod 25 will push the belt tensioning bracket 27 upward, and the belt tensioning pulley 28 will press against the lower surface of the upper end of the belt to help tighten the belt. When the belt becomes loose after long-term use, the reset rod 25 will extend to prevent the belt from loosening after long-term use.

[0033] like Figure 1-4 As shown, the embodiment of the present invention provides an implementation method. Based on the above implementation method, the eccentric wheel 8 is provided with mounting holes 29 in an array shape, and the front end left side of the active rod 9 is connected by a thread.

[0034] From the analysis of the above structure, it can be known that the stroke of the driven plate 10 can be adjusted by selecting the mounting holes 29 in different positions. During installation, it is only necessary to loosen the bolt on the left front end of the active rod 9, and then insert the left front end of the active rod 9 into the interior of the mounting hole 29 and then lock it.

[0035] like Figure 1-4 As shown, an embodiment of the present invention provides an implementation method. Based on the above implementation method, a bearing is inserted and connected to the inside of the mounting hole 29, and the distance between the axis of the mounting hole 29 and the axis of the eccentric wheel 8 is marked next to the mounting hole 29.

[0036] From the analysis of the above structure, it can be seen that the bearing inside the mounting hole 29 can reduce friction, and the distance between the axis of the mounting hole 29 and the axis of the eccentric wheel 8 marked next to the mounting hole 29 can play an auxiliary role in selecting the length.

[0037] like Figure 1-4 As shown, an embodiment of the present utility model provides an implementation method. Based on the above implementation method, a baffle 30 is fixedly connected to the rear end of the bracket 1.

[0038] From the analysis of the above structure, it can be seen that the baffle 30 can isolate the driven plate 10 to prevent the driven plate 10 from hitting the user.
