Abstract
The utility model discloses a pushing rod device which is characterized by comprising a motor, a gear case and a lead screw, wherein a nut is connected onto the lead screw. A transmission shaft is connected at the back of the nut, and the stroke distance of the transmission shaft is controlled by a limit switch. Therefore, when the pushing rod device works, people can control the opening and the closing of a shroud by manipulating the limit switch. Compared with the traditional device, the pushing rod device can have the effect of being simple in structure and convenient to operate.
Description
Technical field
The utility model relates to the lampblack absorber modular construction and improves technical field, says more specifically a kind of simple in structure, easy to operate push rod device.
Background technology
At present, household smoke exhaust ventilator has changed side-suction type for elegant in appearance into by direct absorbing type, when when using side-absorption type smoke exhaust ventilator, directly be to open switch just can work, but after ventilating fan directly is exposed at grid, not only not attractive in appearance, and time one length will amass full dust, affects the operating efficiency of smoke exhaust ventilator, certainly will a cover cap to be installed, but if opening and close manually of cover cap not only bothers, nor energy control angle, can only open or close, can not adaption demand.
Summary of the invention
For the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of simple in structure, easy to operate push rod device.
For achieving the above object, the utility model by the following technical solutions: a kind of push rod device, it is characterized in that it comprises motor, gear-box and screw mandrel, be connected with swivel nut on the described screw mandrel.Be connected with power transmission shaft behind the described swivel nut, the stroke length of described power transmission shaft is controlled by limit switch.
Adopted a kind of push rod device of the present utility model, because by motor, gear-box and screw mandrel combination, be connected with swivel nut and behind swivel nut, be connected with power transmission shaft at screw mandrel, the stroke length of power transmission shaft is controlled by limit switch, when work, just can control the Kai Heguan of cover cap by handling limit switch, compare the effect that can reach simple in structure, easy to operate with legacy equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-motor, 2-gear-box, 3-screw mandrel, 4-swivel nut, 5-power transmission shaft, 6-limit switch.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of push rod device, it is characterized in that, it comprises motor 1, gear-box 2 and screw mandrel 3, be connected with swivel nut 4 on the described screw mandrel 3, at work, rotatablely move after the deceleration through gear-box 2 by motor 1, be converted into rectilinear motion by screw mandrel 3 and swivel nut 4 rotatablely moving; Be connected with power transmission shaft 5 behind the described swivel nut 4, thereby driving power transmission shaft 5 does reciprocating linear motion, the stroke length of described power transmission shaft 5 is by limit switch 6 controls, can control the Kai Heguan of cover cap by limit switch 6, simultaneously can also open or close certain angle to cover cap as required, easy to operate.
