Abstract
The utility model discloses a retractor device, which comprises an upper sheet, a lower sheet and a motor. The upper sheet is provided with a groove, a magnetic retractor piece is inserted in the groove; a magnetic piece is positioned at the position corresponding to the retractor piece on the lower sheet; and the lower sheet is connected with the rotor of the motor. The retractor device has simple structure, long service life and very high market value.
Description
Technical field
The utility model relates to a kind of retractor device, relates in particular to a kind of magnetic field principle of utilizing and carries out automatic extending-contracting apparatus.
Background technology
Thereby general retractor device all is to rely on mechanical force directly to support and stretch, its principle be exactly when stretching out object live by an object money with bearing capacity, this loaded object is easy to cause wearing and tearing in the process of carrying, useful life is short.
The utility model content
The purpose of this utility model is exactly that existing retractor device short defective in useful life, the retractor device that provides a kind of principle of utilizing magnetic field homopolar-repulsion heteropole to inhale mutually to make are provided.
The technical solution of the utility model: a kind of retractor device, comprise synusia, following synusia, motor, fluted on the last synusia, be inserted with extensible member in groove location, this extensible member has magnetic, the position corresponding with extensible member is provided with magnetic part on the following synusia, this magnetic part can be located at down on the upper surface of synusia, also can be located at down in the lamellasome, following synusia is connected with the rotor of motor, rotate along with the rotor rotation of motor, following synusia can be enclosed within on the rotor of motor and by the rotor of motor and run through, when the utility model is connected with the mains, power supply drives motor and rotates, synusia and then rotated together under motor drove when rotating, therefore the magnetic part on following synusia is also rotating, its magnetic field changes when rotating, when the magnetic pole of the magnetic pole of magnetic part and its corresponding extensible member is identical on the synusia instantly, both repel, and extensible member protrudes upward away from magnetic part, when the magnetic pole of the extensible member that the magnetic pole of magnetic part is corresponding with it on the synusia is opposite instantly, both attract, and extensible member is withdrawn downwards near magnetic part.As long as motor drives down synusia always and rotates, then magnetic field changes always, and extensible member will stretch back and forth so, thereby reaches flexible purpose.
The beneficial effects of the utility model: the utility model is simple in structure, and long service life has very high market value.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of synusia and following synusia on the utility model.
Fig. 2 is the structural representation of synusia and motor under the utility model.
Fig. 3 is a schematic diagram of the present utility model.
Description of reference numerals: go up synusia 1, following synusia 2, motor 3, extensible member 11, magnetic part 21, rotor 31.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
Fig. 1 is to a kind of retractor device shown in Figure 3, comprise synusia 1, following synusia 2, motor 3, fluted on the last synusia 1, be inserted with the extensible member 11 that has magnetic in groove location, position corresponding with extensible member 11 on the following synusia 2 is provided with magnetic part 21, magnetic part 21 is located at down on the upper surface of synusia, following synusia 2 is enclosed within on the rotor 31 of motor 3 and by rotor 31 and runs through, when the rotor 31 of motor 3 rotates, magnetic part 21 on following synusia 2 and the following synusia also and then rotates together, stretches up and down thereby drive the extensible member 11 of going up synusia 1 opposite position.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
Claims (3)
1, a kind of retractor device, comprise synusia, following synusia, motor, it is characterized in that synusia is provided with groove, be inserted with magnetoconstriction spare in groove location, the position corresponding with extensible member is provided with magnetic part on the following synusia, and following synusia is connected with the rotor of motor.
2, a kind of retractor device according to claim 1 is characterized in that described magnetic part is located at down on the upper surface of synusia or down in the body of synusia.
3, a kind of retractor device according to claim 1, it is characterized in that described down synusia is enclosed within on the rotor of motor and by the rotor of motor runs through.
