[0023] 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.

[0024] See also Figure 1-6As shown, an electric push rod control structure includes a base 1 with a gear set and a telescopic cylinder body 2, the telescopic cylinder body 2 is connected to the top of the base 1, a rotating rod 3 is rotatably installed on the top of the base 1, the bottom of the rotating rod 3 is connected to the gear set inside the base 1, a driving gear 4 is fixedly installed on the top of the rotating rod 3, and a driving groove is provided on the top of the driving gear 4. Under the action of the driving groove, it is convenient to drive the driving gear 4 and the rotating rod 3 to rotate, so that the gear set in the base 1 rotates, and a protection box 5 is fixedly connected to the top of the base 1. Under the action of the protection box 5, the internal parts thereof can be protected. A top cover 6 is installed on the top of the protection box 5 by countersunk bolts, and a separable electric drive component and a manual drive component are respectively provided in the protection box 5, and a positioning component is also provided on the protection box 5.

[0025] The easily separable electric drive component includes a side-mounted shell 7, a mounting notch is provided on the rear side of the protection box 5, the side-mounted shell 7 is installed on the inner side wall of the mounting notch, a separation screw 8 is rotatably connected to the side-mounted shell 7, a motor fixing seat 9 is screwed on the separation screw 8, a driving motor 11 is connected to the bottom of the motor fixing seat 9 through a mounting bolt 10, a driving block 12 is fixedly installed on the output shaft of the driving motor 11, one end of the driving block 12 is penetrated in the driving groove, when the driving block 12 is penetrated in the groove on the driving gear 4, the rotating driving block 12 can drive the driving gear 4 to rotate, similarly when the driving motor 11 drives the driving block 12 to rise, the driving block 12 can be away from the driving groove, at this time the driving motor 11 cannot drive the driving gear 4 and the rotating rod 3 to rotate through the driving block 12.

[0026] A mounting hole is provided at the front side of the protection box 5 , and a transparent observation glass 13 is fixedly mounted on the inner side wall of the mounting hole. The transparent observation glass 13 facilitates observation of the interior of the protection box 5 .

[0027] The manual drive assembly includes a bottom mounting shell 14, which is fixedly mounted on the top of the base 1. A displacement screw 15 is rotatably connected to the bottom mounting shell 14, and a displacement block 16 is screwed on the displacement screw 15. A driving gear 17 is rotatably mounted on the top of the displacement block 16, and a rotating operating rod 18 is connected to the top of the driving gear 17. An avoidance hole is provided on the top cover 6, and one end of the rotating operating rod 18 is penetrated in the avoidance hole. When the displacement block 16 drives the driving gear 17 and the rotating operating rod 18 to move, the avoidance hole will not affect the displacement of the rotating operating rod 18.

[0028] The positioning assembly includes an L-shaped support block 19, which is installed on the outer side wall of the rear side of the protection box 5. A positioning screw 20 is screwed on the L-shaped support block 19. When the displacement block 16 drives the active gear 17 to engage with the driving gear 4, the rotating operating rod 18 will be at the bottom of the positioning screw 20. Therefore, when the rotating operating rod 18 drives the active gear 17 to rotate, the rotating operating rod 18 and the active gear 17 can be limited and prevented from rotating by rotating and descending the positioning screw 20.

[0029] When the utility model is in use, when the telescopic cylinder 2 needs to work, the user can first make the driving motor 11 work and then drive the driving block 12 to rotate. Since the driving block 12 is inserted into the driving groove of the driving gear 4, the driving gear 4 and the rotating rod 3 can be driven to rotate. Because the bottom of the rotating rod 3 is connected to the gear set in the base 1, the gear set can be rotated. After the gear set works, the linear motion of the telescopic cylinder 2 can be realized. When the driving motor 11 is damaged, the driving motor 11 cannot drive the telescopic cylinder 2 to work. If the telescopic cylinder 2 needs to continue to work, the user can make the separation screw 8 rotate in situ. Under the limit position in the side mounting shell 7, the motor mounting seat can drive the driving motor 11 to rise. When the driving motor 11 rises, it can drive the driving block 12 to rise until the driving block 12 is separated from the driving groove of the driving gear 4.

[0030] Then the user can rotate the displacement screw 15 in situ, so that under the limit of the bottom mounting shell 14, the displacement block 16 can drive the active gear 17 to move until the active gear 17 is meshed with the driving gear 4, and then the user can rotate the driving gear 4 on the displacement block 16 by rotating the operating rod 18, thereby driving the driving gear 4 and the rotating rod 3 to work, so that the gear set can be driven to rotate, and finally the telescopic cylinder 2 can continue to work. It is simple and convenient. After the telescopic cylinder 2 is telescoped, the user can rotate the positioning screw 20 and tighten the rotating operating rod 18 to limit the rotating operating rod 18 and the active gear 17 to prevent rotation.
