It has the following disadvantages: the gearbox of the small motor is easy to damage and does not have the function of preventing the locked rotor. And the gear and rack transmission is carried out by adopting multi-stage speed reduction, so that the structure is more complex and the failure rate is high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a prevent stifled commentaries on classics lock with stroke position detects, it has prevents stifled commentaries on classics function, and simple structure, fault rate are low.
The technical scheme of the utility model is realized like this: the anti-blocking rotary lock with the stroke position detection function comprises a motor, a cam arranged on an output shaft of the motor, a transmission piece meshed with the cam and a rack, wherein the transmission piece comprises a transmission end, a connecting end and an optical axis, the transmission end is clamped in the cam and meshed with the cam, the connecting end extends outwards from the end face of the transmission end along the direction of the central axis of the connecting end, and the optical axis is fixed on the connecting end; the connecting end is provided with a gear meshed with the rack, an optical axis fixing sleeve is mounted on the optical axis, gaskets are arranged between the connecting end and the optical axis, two gaskets are arranged at intervals, and a spring is mounted between each gasket and the corresponding gasket; and a magnetic steel mounting part is arranged on the rack.
Further, the output shaft of the motor is provided with a first gasket.
According to the technical scheme, the clutch cam and the clutch gear clutch structure are arranged in the lock body. When the locked rotor is generated, the clutch gear in the lock body can compress the compression spring on the right side to move towards the right side and separate from the clutch cam. When the gear rotates over the highest clutch point, the cam and the gear can be reset by the aid of the elastic force of the spring. According to the principle, when the input and output torque is too large, the separating device is separated protectively, and the two sides of the connection are protected from being damaged due to too large torque.
The locked object contains magnetic steel, and the corresponding lock body position is equipped with Hall detection element. When the locked object moves to the right position, the Hall element in the lock body can detect a magnetic field signal, so that the position of the locked object can be accurately positioned.
In addition, the gear is adopted to directly drive the rack to transmit, so that the transmission structure is simple and the problem is not easy to occur.
To sum up, the utility model has the advantages that: 1. has the function of anti-locked rotation; 2. the gear is adopted to directly drive the rack to transmit, so that the transmission structure is simple and the failure rate is low; 3. the position of the locked object can be accurately positioned.
Drawings
FIG. 1 is a schematic structural diagram of the present embodiment;
FIG. 2 is a schematic view of an exploded structure of the present embodiment;
wherein, 1, a motor; 2. a cam; 3. a transmission member; 4. a rack; 5. a transmission end; 6. a connecting end; 7. an optical axis; 8. a gear; 9. an optical axis fixing sleeve; 10. a gasket; 11. a spring; 12. A magnetic steel mounting part; 13. a first gasket.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-2, the anti-blocking twist lock with stroke position detection comprises a motor 1, a cam 2 mounted on an output shaft of the motor 1, a transmission member 3 engaged with the cam 2, and a rack 4, wherein the transmission member 3 comprises a transmission end 5 engaged with the cam 2 and engaged therewith, a connection end 6 extending outwards from an end surface of the transmission end 5 along a central axis direction thereof, and an optical axis 7 fixed on the connection end 6; a gear 8 meshed with the rack 4 is arranged on the connecting end 6, an optical axis fixing sleeve 9 is arranged on the optical axis 7, two gaskets 10 are arranged between the connecting end 6 and the optical axis 7 at intervals, and a spring 11 is arranged between each gasket 10 and each gasket 10; and a magnetic steel mounting part 12 is arranged on the rack 4. A first spacer 13 is mounted on the output shaft of the motor 1.
According to the technical scheme, the clutch cam 2 and the clutch gear 8 are arranged in the lock body and are in clutch structure. When the locked rotor is generated, the clutch gear 8 inside the lock body compresses the compression spring 11 on the right side to move towards the right side and the clutch cam 2 is separated. When the gear 8 rotates to the highest clutch point, the cam 2 and the gear 8 can reset the gear 8 and the cam 2 by the elastic force of the spring 11. According to the principle, when the input and output torque is too large, the separating device is separated protectively, and the two sides of the connection are protected from being damaged due to too large torque.
The locked object contains magnetic steel, and the corresponding lock body position is equipped with Hall detection element. When the locked object moves to the right position, the Hall element in the lock body can detect a magnetic field signal, so that the position of the locked object can be accurately positioned.
In addition, the gear 8 is adopted to directly drive the rack 4 for transmission, so that the transmission structure is simple and the problem is not easy to occur.
