Abstract
The utility model discloses a lead screw limiter with a fine adjustment function. The lead screw limiter comprises a lead screw and a lead screw base. The lead screw comprises a threaded rod driven by a motor and a slider nut arranged on the threaded rod in a threaded mode; the slider nut is provided with an ejector rod, the end portion of the threaded rod is fixedly connected with a limiting plate, the limiting plate is provided with a microswitch, the microswitch is electrically connected with a controller, the controller is electrically connected with the motor, and the ejector rod is moveably arranged on the slider nut. The lead screw limiter with the fine adjustment function is simple in structure and easy to realize; the ejector rod is moveably arranged on the slider nut, fine adjustment can be achieved just by moving the ejector rod once deviation happens, and therefore the lead screw limiter with the fine adjustment function is convenient and easy to operate.
Description
Technical field
The utility model relates to a kind of screw rod limiter with fine adjustment function.
Background technique
Electric-powered shutter, has another name called electric shutter blind, and it,, by the kind of drive of using the lifting of driven by motor blade to replace traditional blind to pull, has breakthrough innovation, makes it easier and follow one's bent in operating process.Snubber is one of important component part of electric-powered shutter operation.At present, the spacing adjusting of the screw rod limiter on market is by the number of turns, to calculate blind height and adjusted position according to spiral size, once there is deviation, in the time of regulating, operates comparatively loaded down with trivial detailsly, give to install, attendant brings inconvenience.
Model utility content
The purpose of this utility model is for the problems referred to above, and a kind of screw rod limiter with fine adjustment function is provided, while regulating to solve existing screw rod limiter, and the problem of complex operation.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of screw rod limiter with fine adjustment function, comprise screw mandrel and screw rodb base, described screw mandrel comprises by motor-driven screw rod and screw thread and is arranged on the slider nut on screw rod, on described slider nut, be provided with push rod, the end of described screw rod is fixedly connected with limiting board, on described limiting board, is provided with sensitive switch, and described sensitive switch is electrically connected to controller, described controller is electrically connected to motor, and described push rod is movably arranged on slider nut.
Further, described push rod is threaded with slider nut.
The beneficial effects of the utility model are, described a kind of screw rod limiter with fine adjustment function is simple in structure, is easy to realize, its push rod is movably arranged on slider nut, once there is deviation, only needs mobile push rod position, can realize fine setting, easy to operate, simple.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation with the screw rod limiter of fine adjustment function of the utility model.
In figure:
1, screw rod; 2, slider nut; 3, screw rodb base; 4, limiting board; 5, push rod.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
Please refer to shown in Fig. 1, Fig. 1 is a kind of structural representation with the screw rod limiter of fine adjustment function of the utility model; In the present embodiment, a kind of screw rod limiter with fine adjustment function, comprise screw mandrel and screw rodb base 3, described screw mandrel comprises by motor-driven screw rod 1 and screw thread and is arranged on the slider nut 2 on screw rod 1, on described slider nut 2, be provided with push rod 5, the end of described screw rod 1 is fixedly connected with limiting board 4, on described limiting board 4, be provided with sensitive switch (not illustrating in figure), described sensitive switch is electrically connected to controller, described controller is electrically connected to motor, described slider nut 2 has tapped hole, on described push rod 5, is provided with the outside thread matching with this tapped hole.
When occurring that deviation need to regulate, only need the push rod 5 on turning block nut 2, push rod 5 is moved forward or backward, thereby realize fine setting, convenient and simple for operation.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
