Abstract
The utility model discloses a lead screw structure of a double sliding pair swing guide rod structure of an elevator. Threads are processed on a lead screw body and meshed with a transmission nut to form the lead screw structure. The lead screw structure is reasonable in design and convenient in use, improves running efficiency and reduces noise.
Description
Affiliated technical field
The utility model relates to a kind of elevator corollary apparatus, and the screw structure of the two moving sets pendulum guide rod structures of particularly a kind of elevator is applicable to elevator.
Background technology
At present, the circular arc door machine of elevator adopts two moving sets oscillating guidebar mechanisms, and its straight line movable part uses the four-wheel support board structure, and friction drag in service is big and running precision is not high, and the power of motor of requirement is big.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and the screw structure of the two moving sets pendulum guide rod structures of a kind of elevator is provided.This screw structure is not only reasonable in design, and is easy to use, and improves operating efficiency and reduce noise.
The technical solution adopted in the utility model is: leading screw body design is processed with screw thread, is connected with a joggle with driving nut and constitutes.During use, the screw structure of the two moving sets oscillating guidebar mechanisms of the utility model design-calculated elevator is connected and installed in the door-opening mechanism of elevator and gets final product.
The structure design characteristic of the screw structure of the two moving sets oscillating guidebar mechanisms of the utility model design-calculated elevator: utilize the positive and negative rotation of variable-frequency motor, drive the motion annex on the motor, drive timing belt, drive adapter shaft on the leading screw simultaneously, and left-right turning screw rod motion simultaneously, directly driven the leading screw axle sleeve.The pulling linear slider is prolonged line slideway to both sides and is done straight-line motion, the linear slider direct pull connects the linear bearing connecting panel on the slide block, extend motion before and after having driven linear bearing synchronously, linear bearing has driven pendulum guide rod one end and has moved to both sides, be connected on the main shaft owing to the pendulum guide rod other end simultaneously, it is the circular motion at center that pendulum guide rod drive rod end bearing is done with the main shaft, and rod end bearing directly drives the circular arc door and does circular motion.
The beneficial effects of the utility model are, and are rational in infrastructure, easy to use, improve operating efficiency and reduce noise.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Accompanying drawing number is: 1, leading screw body, 2, screw thread, 3, driving nut.
The specific embodiment
With reference to Fig. 1, leading screw body 1 design is processed with screw thread 2, is connected with a joggle with driving nut 3 and constitutes.During use, the screw structure of the two moving sets oscillating guidebar mechanisms of the utility model design-calculated elevator is connected and installed in the door-opening mechanism of elevator and gets final product.
The structure design characteristic of the screw structure of the two moving sets oscillating guidebar mechanisms of the utility model design-calculated elevator: utilize the positive and negative rotation of variable-frequency motor, drive the motion annex on the motor, drive timing belt, drive adapter shaft on the leading screw simultaneously, and left-right turning screw rod motion simultaneously, directly driven the leading screw axle sleeve.The pulling linear slider is prolonged line slideway to both sides and is done straight-line motion, the linear slider direct pull connects the linear bearing connecting panel on the slide block, extend motion before and after having driven linear bearing synchronously, linear bearing has driven pendulum guide rod one end and has moved to both sides, be connected on the main shaft owing to the pendulum guide rod other end simultaneously, it is the circular motion at center that pendulum guide rod drive rod end bearing is done with the main shaft, and rod end bearing directly drives the circular arc door and does circular motion.
Claims (1)
