Abstract
The utility model relates to a transmission mechanism, in particular to the transmission mechanism of a lifter. The transmission mechanism of the lifter comprises a lifting connecting rod being connected with a motor, and the transmission mechanism is characterized in that the motor drives a worm and gear matched with a lifting connection rod, an end with a hole is arranged at the bottom of the lifting connection rod, a short shaft penetrates through the hole to be connected onto the lifting connecting rod, and the other end of the short shaft is connected onto a gate plate. A gear is a ladder-shaped lead screw nut. The transmission mechanism has the advantages of optimizing the existing transmission mechanism, enabling the transmission mechanism to be used on a sliding-cover type gate, and being compact in structure, high in operation accuracy, stable in transmission and applicable to wide application.
Description
(1) technical field
The utility model relates to driving mechanism, particularly a kind of lifter driving mechanism.
(2) background technique
Usually gate adopts hoist to carry out transmission, but the whole product line of hoist is often used for big-and-middle-sized gate, the sliding cover type gate is because its doorframe height is lower, can adopt the lift of compact structure, this driving mechanism is comparatively responsive to eccentric force, and the sliding cover type gate is because depart from gate framework center of gravity, therefore certain horizontal component is arranged, in order to overcome this horizontal component, need to be optimized improvement to existing driving mechanism.
(3) summary of the invention
The utility model provides a kind of compact structure in order to make up the deficiencies in the prior art, the lifter driving mechanism of stable working.
The utility model is achieved by the following technical solution:
A kind of lifter driving mechanism comprises the lifting linking member that connects motor, it is characterized in that: described motor also drives the worm and gear that is matched with lifting linking member; Described lifting linking member bottom is provided with termination with holes, and minor axis passes the hole and is connected on lifting linking member, and the minor axis the other end is connected on flashboard.
Described worm gear is the trapezoidal screw nut.
The beneficial effects of the utility model are: the lifter driving mechanism of this model utility is optimized existing driving mechanism, and it can be used on the sliding cover type gate, compact structure, and running precision is high, and stable drive is suitable for extensive use.
(4) description of drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 motor, 2 lifting linking members, 3 terminations, 4 minor axises, 5 flashboards.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises the lifting linking member 2 that connects motor 1, it is characterized in that: described motor 1 also drives the worm and gear that is matched with lifting linking member 2; Described lifting linking member 2 bottoms are provided with termination with holes 3, and minor axis 4 passes the hole and is connected on lifting linking member 2, and minor axis 4 the other ends are connected on flashboard 5, and described worm gear is the trapezoidal screw nut.
Adopt lifter driving mechanism of the present utility model, driving worm and gear by motor 1 slows down, worm gear is the trapezoidal screw nut, drive lifting linking member 2 knee-actions, the minor axis 4 of lifting linking member 2 bottoms drives flashboard 5 and carries out lifting action, the minor axis 4 that is arranged on lifting linking member 2 bottoms can overcome the horizontal component of sliding cover type gate, offsets the unbalanced force of a part, improves running precision.
Claims (2)
1. a lifter driving mechanism, comprise the lifting linking member (2) that connects motor (1), and it is characterized in that: described motor (1) also drives the worm and gear that is matched with lifting linking member (2); Described lifting linking member (2) bottom is provided with termination with holes (3), and minor axis (4) passes the hole and is connected on lifting linking member (2), and minor axis (4) the other end is connected on flashboard (5).
2. lifter driving mechanism according to claim 1, it is characterized in that: described worm gear is the trapezoidal screw nut.
