DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 3 , an electric push rod stroke control mechanism, including a box body 1, a cylinder body 2 is provided on the top of the box body 1, a push rod body 3 is provided in the cylinder body 2, a box door 4 is provided on the box body 1, a handle 5 is provided on the box door 4, and a stroke adjustment component connected to the push rod body 3 is provided in the box body 1;

[0020] The stroke adjustment assembly includes a motor 8 fixedly mounted on the inner wall of one side of the box body 1, the output shaft of the motor 8 is fixedly connected to the connecting shaft 9, a circular plate 7 is fixedly mounted on the connecting shaft 9, a control frame 16 is provided on the side of the circular plate 7 away from the motor 8, a control rod 15 is provided through the control frame 16 and is slidably connected to the inner wall thereof, two connecting rods 6 are provided on the top of the box body 1 and are slidably connected thereto, one end of the two connecting rods 6 located outside the box body 1 extends into the cylinder body 2 and is fixedly connected to the bottom of the push rod body 3, one end of the two connecting rods 6 located inside the box body 1 is fixedly connected to the top of the control frame 16, and a control groove is provided on the side wall of the circular plate 7 close to the control frame 16 10. A control screw 11 is rotatably connected between the inner walls at both ends of the control groove 10. A control block 14 is threadedly sleeved on the outer wall of the control screw 11. The control rod 15 is rotatably connected to the control block 14. One end of the control screw 11 passes through the inner wall of one side of the control groove 10 and is fixedly installed with a control knob 12 located outside the control groove 10. The control block 14 is slidably connected to the inner walls on both sides of the control groove 10. A plurality of evenly distributed anti-slip protrusions 13 are provided on the outer wall of the control knob 12. By providing the anti-slip protrusions 13, the friction force can be increased to prevent the hand from slipping. A scale line 17 is provided on the circular plate 7, and a pointer 18 is provided on the side of the control block 14 close to the scale line 17.

[0021] When the present invention is in use, starting the motor 8 can rotate the connecting shaft 9 and the circular plate 7, thereby making the control rod 15 rotate around the axis of the connecting shaft 9. Since the control rod 15 is located inside the control frame 16, the control rod 15 slides inside the control frame 16, and the control frame 16 moves up and down. The setting of the connecting rod 6 can make the push rod body 3 move up and down in the cylinder body 2. When the stroke needs to be adjusted, the box door 4 is opened by the handle 5, and the control knob 12 is turned to rotate the control screw 11. Since the control block 14 is slidably connected to the inner walls on both sides of the control groove 10 and cannot rotate, the control block 14 moves back and forth in the control groove 10, thereby adjusting the rotation radius of the control rod 15, thereby realizing the adjustment of the up and down movement distance of the control frame 16 and the push rod body 3. By setting the scale line 17 and the pointer 18, the stroke size can be controlled more intuitively, which is more convenient to use.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
