Technical field
The present invention relates to self-locking device, relate in particular to a kind of miniature motor self-locking.
Background technology
The application of minitype speed reducing motor more and more widely still is with the micromachine of gear reduction unit all not have auto-lock function at present, perhaps only could realize self-locking under the situation of speed reducing ratio very high (greater than 300: 1).This do not have the motor of auto-lock function to limit its range of application to a great extent.Such as electrically driven curtain, motor is not only wanted and can be risen to specified altitude assignment to curtain, and wants to stop at specified altitude assignment.If there is not auto-lock function, can under the action of gravity of curtain, reverse after the motor stall, curtain can not be parked in assigned address.If use the very high minitype speed reducing motor of speed reducing ratio to realize self-locking, then under the condition of identical output speed, require rotating speed of motor very high, such as 80 rev/mins of outputs, speed reducing ratio 300: 1, then rotating speed of motor is up to 24000 rev/mins.A series of shortcomings such as motor speed is too high, can bring noise big, and the life-span is short.
Summary of the invention
The present invention is intended to solve the problem that existing micromachine is difficult to self-locking, and a kind of miniature motor self-locking device is provided.The present invention is simple in structure, and can realize the self-locking of micromachine.
The present invention is achieved in that a kind of miniature motor self-locking device, and it comprises the pedestal that micromachine is installed, and institute's pedestal is the coaxial sleeve pipe in hole that comprises flat board that a middle part is with holes and and middle part, and the output shaft of described micromachine passes from this sleeve pipe;
One torsion spring, it is sleeved on the sleeve pipe of described pedestal, and its two ends are protruding;
One drives the conversion sleeve pipe, and it is the double-decker of both ends open, and its inner ring length is greater than the outer ring and utilize its openend to insert in the sleeve pipe of pedestal, and described motor output shaft is positioned at wherein and drives and is connected on the inner ring that drives the conversion sleeve pipe; The race diameter of described driving conversion sleeve pipe is greater than the pedestal sleeve pipe and have circumferential breach, this breach all be contained in the two ends of described torsion spring projection interior so that motor when rotating torsion spring by from the pushing of the projection outside and rotated;
A load connector, it is the sleeve of a both ends open, and the one end is enclosed within and drives on the conversion sleeve pipe, and is connected with its driving, and the other end is the link of load.
Described miniature motor self-locking device, one end inside of coad connector have and drive that breach on the swivel sleeve cooperates axial raised line, and two projectioies of described torsion spring lay respectively at the two side of raised line and drive in the space between the side of breach on the swivel sleeve so that the axial raised line of motor coad connector when stopping from the inboard pushing torsion spring of torsion spring two ends projection when protruding, torsion spring is held the sleeve pipe of motor base tightly, realizes self-locking thereby can't rotate.
Described miniature motor self-locking device, described motor shaft with drive that conversion sleeve pipe inner ring is connected with key and with radially screw.
Described miniature motor self-locking device, described coad connector is sleeved on the periphery that drives that section on the swivel sleeve and is provided with two relative slotted holes, and the outer ring of described driving swivel sleeve has carving piece and snapping in the described slotted hole of two and described slotted hole position correspondence.
The present invention only just realizes the self-locking of micromachine with four parts, the self-locking device of the high speed reducing ratio gear box of the sort of relatively usefulness has not only reduced the noise of pot motor, prolong electrical machinery life, simple in structure and easy to use, the stabilization of equipment performance height, cost is low.Proposition of the present invention stops the means easily that provide for roll-type window or door at arbitrary height.
