[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 The utility model provides a technical solution for an electric push rod that is easy to assemble:

[0019] according to Figure 1-3 As shown, it includes a base 1, an electric push rod body 5 is fixedly provided on the top of the base 1, an input shaft sleeve 6 is fixedly provided on the side of the base 1, a fixing ring 2 is fixedly provided at the center of the side of the base 1, a stepper motor 3 is nested inside the fixing ring 2, and the output end of the stepper motor 3 extends to the inside of the base 1 and is fixedly connected to the input shaft sleeve 6, grooves 7 are provided on both sides of the inner wall of the base 1, blocks 8 are nested inside the two grooves 7, reset springs 15 are fixedly installed on both sides of the bottom of the two grooves 7, one end of the reset spring 15 is fixedly connected to the corner of the side of the block 8, and slots 9 are provided on both sides of the stepper motor 3, and the block 8 is engaged with the slots 9.

[0020] Specifically, the stepper motor 3 is fixed to the base 1 by the cooperation of the fixing ring 2 and the block 8. The rotation of the rotating rod 4 drives the rotation of the gear 14. The gear 14 is meshed and connected with the connecting strip 12, and the movement of the block 8 is controlled by the cooperation of the reset spring 15, so that the block 8 is engaged and separated from the slot 9. When installing the stepper motor 3 that replaces the traditional electric push rod, the base 1 and multiple sets of screws need to be installed in cooperation, which effectively improves the assembly efficiency of the electric push rod.

[0021] according to Figure 1 , Figure 2 and Figure 3 As shown, a connecting strip 12 is provided at the center of the back of the two blocks 8, and a tooth groove 13 is provided on the side of the two connecting strips 12. Rotating rods 4 are rotatably connected at the two corners of the top of the base 1. The bottom ends of the two rotating rods 4 extend to the inside of the groove 7. Gears 14 are fixedly installed at the bottom of the two rotating rods 4, and the gear 14 is meshed with the tooth groove 13.

[0022] Specifically, the rotating rod 4 drives the gear 14 to rotate, and the gear 14 engages with the tooth groove 13 on the side of the connecting bar 12, thereby driving the connecting bar 12 to move, and the movement of the connecting bar 12 drives the block 8 to move.

[0023] A stopper 11 is fixedly mounted at the end of the connecting bar 12 , and the size of the stopper 11 is larger than the size of the end of the connecting bar 12 . The setting of the stopper 11 at the end of the connecting bar 12 prevents the connecting bar 12 from being separated from the gear 14 .

[0024] An insertion hole 10 is provided at a position where the side wall of the groove 7 is aligned with the stopper 11 , and the size of the insertion hole 10 is the same as that of the stopper 11 .

[0025] Specifically, because the insertion hole 10 and the stopper 11 have the same size, when the connecting bar 12 moves, the connecting bar 12 can be moved into the insertion hole 10 , thereby expanding the moving distance of the block 8 .

[0026] A sealing ring is sleeved at the connection between the stepper motor 3 and the fixed collar 2. The sealing ring effectively improves the sealing performance at the connection position and reduces the entry of dust.

[0027] A mounting flange is fixedly provided at the bottom end of the base 1. Specifically, the installation of the electric push rod and the connection position is facilitated by the provision of the mounting flange.

[0028] Working principle: The utility model is an electric push rod that is easy to assemble. When the stepping motor 3 of the electric push rod needs to be assembled with the base 1, firstly, the rotating rod 4 at the two corners of the top of the base 1 is manually rotated, and the rotating rod 4 drives the gear 14 to rotate. The rotation of the gear 14 drives the connecting bar 12 to move. The movement of the connecting bar 12 drives the clamping block 8 to move toward the inside of the groove 7. At this time, the reset spring 15 is under pressure and is in a compressed state. Then, the stepping motor 3 is nested into the inside of the fixed ring 2, and the output shaft of the stepping motor 3 is fixedly connected to the input shaft sleeve 6. Then, the rotating rod 4 is manually released. At this time, the clamping block 8 is squeezed by the reset spring 15 and engages with the clamping groove 9 opened on the side of the stepping motor 3, thereby completing the assembly between the stepping motor 3 and the base 1.
