Abstract
A portable motion control device of electric push-rod adjusts and fixes the microswitch position by the stretching of the folding wire and the tooth shaped structure, therefore the electric push-rod motion is adjusted and the applicability of product is increased with no influence to the product appearance.
Description
Technical field
What the utility model was related is a kind of travel control device, particularly a kind of portable travel control device of electric pushrod.
Background technology
The Stroke Control of traditional electric pushrod is the break-make by the fixed length of the push rod stroke power supply when corresponding stationkeeping is installed two microswitches and controlled push rod respectively and run to forward and backward dead-centre position.The stroke of this device control is a fixed length, can not regulate, be difficult to satisfy the client stroke of push rod is regulated within the specific limits, and the requirement that Stroke Control is reliable, adjusting is easy for installation.
Summary of the invention
The purpose of this utility model is to provide a kind of portable travel control device, and can satisfy the stroke of push rod is regulated within the specific limits, and the requirement that Stroke Control is reliable, adjusting is easy for installation.
In order to reach described purpose, the utility model provides a kind of portable travel control device of electric pushrod, form by a housing, a driving control system and a motor, a worm gear pairs, described driving control system, described motor and described worm gear pairs are fixed in the described housing, and described driving control system is made up of a screw mandrel, a portable travel switch, a nut, a guide pipe and a positioning strip; Described screw mandrel is connected with the worm gear of described worm gear pairs; The worm screw of described worm gear pairs is connected with described motor, and described nut sleeve and moves up and down with the rotation of described screw mandrel on described guide pipe, and described portable travel switch places guiding tube seat and the inner line that forms of described nut to contact.
The utility model also further provides a kind of portable travel control device of electric pushrod, the portable travel switch is connected two microswitches and is formed by a positioning block, a fold line, wherein a microswitch is fixed on the described guide pipe, another microswitch is connected with locating piece, locating piece can move in the guiding tube seat with the positioning strip engagement that is fixed on the described guide pipe, described locating piece and microswitch.
According to the utility model as can be known, no matter stroke designs longly and weak point, and this electric pushrod is all unaffected, and the design of portable travel switch can make the stroke of electric pushrod regulate within the specific limits; Use fold line, avoid when adjustment stroke, needing the existing potential faults that contracts is spun out or pushed away to power lead, use profile of tooth to mediate fixedly microswitch, thereby make the stroke adjustment control device of electric pushrod convenient, reliable stroke adjustment.
