SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a gear drive structure has gear motor gear and drives and do elevating movement rather than the rack gear of meshing, can guarantee gear drive structure normal operating, can not cause the beneficial effect of damage to gear motor to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a gear drive structure, includes gear box, gear rack and gear motor, and in the gear box was located to the gear rack, and the tip extended the gear box, gear rack and gear box parallel arrangement, gear motor one end was equipped with motor rotation axis, is fixed with motor gear on gear motor's the motor rotation axis, and motor gear is connected with the gear rack meshing, and gear motor's motor rotation axis driving motor gear.
As a further aspect of the present invention: the side of the gear strip is provided with a sliding groove, a sliding rail matched with the sliding groove is arranged in the gear box, and the gear strip is connected with the gear box in a sliding mode.
As a further aspect of the present invention: the gear rack is in a strip shape.
As a further aspect of the present invention: the outside of motor gear is equipped with the guard shield, and the guard shield is the cavity form, guard shield and gear box inboard fixed connection.
As a further aspect of the present invention: the gear box is provided with a positioning hole.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses gear drive structure passes through gear motor and drives gear motor rotation axis rotation, and gear motor rotation axis drives gear motor gear synchronous revolution, and gear motor gear further drives and is elevating movement rather than the rack of meshing, because rack and gear motor can work independently, even gear motor stop work, also can manually make the rack be elevating movement to can guarantee gear drive structure normal operating, and can not cause the damage to gear motor.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-2, in an embodiment of the present invention, a gear transmission structure, including gear box 1, rack 2 and gear motor 3, the mid-mounting of rack 2 is in gear box 1, and both ends extend gear box 1, rack 2 and gear box 1 parallel arrangement, and can be elevating movement on gear box 1, 3 one ends of gear motor are equipped with motor rotation axis 4, be fixed with motor gear 5 on gear motor 3's the motor rotation axis 4, motor gear 5 is connected with the meshing of rack 2, 4 driving motor gears 5 of motor rotation axis 4 of gear motor 3 are synchronous rotary motion, motor gear 5 further drives rack 2 and is elevating movement. The utility model discloses gear drive structure passes through gear motor 3 and drives 3 rotation axis rotations of gear motor, gear motor 3 rotation axis drives 3 gear synchronous rotations of gear motor, gear motor 3 gear further drives and is elevating movement rather than the rack gear 2 of meshing, because rack gear 2 and gear motor 3 can independent work, even gear motor 3 stop work, also can manually make rack gear 2 be elevating movement to can guarantee gear drive structure normal operating, and can not cause the damage to gear motor 3.
As a further aspect of the present invention: further, the gear strip 2 is a long strip, a sliding groove is formed in the side face of the gear strip 2, a sliding rail matched with the sliding groove is arranged in the gear box 1, the gear strip 2 is connected with the gear box 1 in a sliding mode, the sliding groove is formed in the gear strip 2, and the sliding rail is arranged in the gear box 1, so that the gear strip 2 can smoothly move up and down on the gear box 1.
As a further aspect of the present invention: a shield 6 is arranged on the outer side of the motor gear 5, the shield 6 is hollow, the shield 6 is fixedly connected with the inner side of the gear box 1, and the shield 6 can effectively protect the motor gear 5 and the gear strip 2; furthermore, a positioning hole 7 is formed in the gear box 1, so that the gear box 1 can be conveniently fixed.
The utility model discloses gear drive structure passes through gear motor 3 and drives 3 rotation axis rotations of gear motor, gear motor 3 rotation axis drives 3 gear synchronous rotations of gear motor, gear motor 3 gear further drives and is elevating movement rather than the rack gear 2 of meshing, because rack gear 2 and gear motor 3 can independent work, even gear motor 3 stop work, also can manually make rack gear 2 be elevating movement to can guarantee gear drive structure normal operating, and can not cause the damage to gear motor 3.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
