Abstract
Description
Technical Field
[0001] This utility model relates to the field of opening and closing devices, and in particular to a fully enclosed single-motor synchronous opening and closing device. Background Technology
[0002] Existing opening and closing devices mostly use two motors to control one opening and closing plate, thereby making the plates move closer and further apart. This method requires two motors, which is costly; moreover, it requires good coordination between the two motors to achieve proper opening and closing, which has its shortcomings in use.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a fully enclosed single-motor synchronous opening and closing device, which reduces the number of motors used, reduces costs, and is convenient to use.
[0005] The technical solution of this utility model is as follows: A fully enclosed single-motor synchronous opening and closing device is provided, comprising: a mounting box, a motor mounted on the outside of the mounting box, a first ball screw, a second ball screw, a first screw nut cooperating with the first ball screw, a second screw nut cooperating with the second ball screw, a first opening and closing plate connected to the first screw nut, a second opening and closing plate connected to the second screw nut, a first coupling connecting the first ball screw and the output shaft of the motor, and a second coupling connecting the first screw nut and the second screw nut; the mounting box includes: a box body with an opening, and a telescopic bellows cover sealing the opening; the first ball screw, the second ball screw, the first screw nut, the second screw nut, the first coupling, and the second coupling are disposed in the box body, the first opening and closing plate and the second opening and closing plate are disposed on the outside of the telescopic bellows cover, and the thread directions of the first ball screw and the second ball screw are opposite.
[0006] In application, the motor runs, and the first and second ball screws rotate. Since the threads of the first and second ball screws are in opposite directions, the first and second screw nuts move simultaneously in opposite directions (towards or away from each other), thus opening and closing the first and second opening / closing plates. Because only one motor is used for opening and closing, it allows for synchronous start and stop of the first and second opening / closing plates, simplifying application. Furthermore, since only one motor is needed, it eliminates the need for another motor, effectively reducing costs.
[0007] Furthermore, the fully enclosed single-motor synchronous opening and closing device also includes: guide rails installed on both sides inside the mounting box, and sliders that cooperate with the guide rails; both ends of the first opening and closing plate and the second opening and closing plate are respectively connected to a slider. The guide rails and sliders enable the movement of the first opening and closing plate and the second opening and closing plate to be more stable and prevent wobbling.
[0008] Furthermore, the fully enclosed single-motor synchronous opening and closing device further includes: a sensing plate installed on the first or second opening and closing plate, and several sensors installed on the housing, wherein the movement range of the sensing plate extends through the sensing range of the sensors. The sensors are optocouplers; the positions of the first and second opening and closing plates are determined by sensing the optocouplers through the sensors.
[0009] Furthermore, the fully enclosed single-motor synchronous opening and closing device also includes: a sensor mounting plate installed on the housing, and the sensor is mounted on the sensor mounting plate.
[0010] Furthermore, a movable slot is provided on the side of the housing, through which the sensing element passes, and the sensor is mounted below the movable slot. The movable slot provides space for the sensing element to move.
[0011] Furthermore, the fully enclosed single-motor synchronous opening and closing device also includes: four support seats installed inside the housing, bearings installed on the support seats, and the first ball screw and the second ball screw passing through the inner rings of the two bearings respectively.
[0012] Furthermore, the fully enclosed single-motor synchronous opening and closing device also includes: a cover mounting plate installed on the first opening and closing plate and the second opening and closing plate, and the telescopic bellows protective cover is installed on the cover mounting plate.
[0013] By adopting the above solution, this utility model provides a fully enclosed single-motor synchronous opening and closing device. Since only one motor is used to realize the opening and closing, it can realize the synchronous start and stop of the first opening and closing plate and the second opening and closing plate, which is convenient to use. At the same time, since only one motor is needed, one motor can be saved, which can effectively reduce costs. Attached Figure Description
