The base plate 10 is provided with two pulleys 14 for a timing belt or a chain, and one of the pulleys 14 is in transmission connection with the power element 13. A timing belt or chain is trained about the outside of the pulley 14. The synchronous belt or chain can rotate in a certain interval to drive the baffle 12 to reciprocate in a certain interval.

Preferably, the baffle 12 is fixedly connected with the transmission member 11 through a clamping plate 15, and the baffle 12 is driven to move by the rotation of a synchronous belt or a chain. This controls the movement of the flap 12 by controlling the rotation of the power member 13.

Wherein the barrier 12 is slidably coupled to one side of the base plate 10 for compactness of the structure. The transmission member 11 is disposed on the other side of the base plate 10. The flap 12 extends to the other side of the base plate 10 via a clamping plate 15 and is coupled to the transmission element 11 so that the transmission element 11 can move the flap 12.

Referring to fig. 2, 3 and 5, a rail 16 is provided on one side of the base plate 10 for the motion stability of the barrier 12. The baffle 12 is slidably coupled to the rail 16. Limiting blocks 17 are arranged at the two motion limit ends of the track 16. Preferably, for more stable movement of the flap 12, two rails 16 are provided in parallel on the base plate 10, such that the flap 12 is slidably coupled to both rails 16.

Two baffles 12 are arranged close to the belt wheel 14, one baffle 12 is fixedly connected with a synchronous belt on the upper side of the belt wheel 14, and the other baffle 12 is fixedly connected with a synchronous belt on the lower side of the belt wheel 14, so that the two baffles 12 move oppositely when the power part 13 rotates forwards, and the two baffles 12 move reversely when the power part rotates backwards.

Preferably, referring to FIG. 2, the pulley 14 is coupled to the baseplate 10 by a tensioning mechanism 18. The tension mechanism 18 includes a tension plate 181 slidably coupled to the base plate 10, and a screw member 182 having one end fixed to the tension plate 181 and the other end screw-coupled to the base plate 10. The pulley 14 is fixed on the tension plate 181, and the position of the tension plate 181 is adjusted by the screw member 182 to adjust the position of the pulley 14, so that the tightness of the timing belt can be adjusted.

Preferably, referring to fig. 2 to 3, the power member 13 is a motor. The motor is fixed to the base plate 10 on one side of the driving member 11. The motor is connected with the belt wheel 14 in a transmission way through a motor synchronous belt 19.

An adjusting screw 23 is arranged at one end of the mounting plate 22 in the sliding direction, and the adjusting screw 23 is in threaded connection with the mounting frame 21. The positions of the adjusting screw 23 and the mounting frame 21 are adjusted to adjust the position of the mounting plate 22, so that the position of the motor can be adjusted to adjust the tightness of the motor synchronous belt 19.

Referring to fig. 2 to 3, a sensor 24 is disposed on the base plate 10 at a middle position of the stroke of the baffle 12. The sensor 24 is capable of detecting the position of the movement of the flapper 12 and if the flapper 12 moves to the extreme open or closed position, the sensor 24 will be triggered to control the stalling of the motor.

The utility model discloses a translation stop gear has two states: an open state (see fig. 4 and 5) and a closed state (see fig. 6 and 7).

The motor drives the belt wheel 14 to rotate, the belt wheel 14 drives the left baffle 121 and the right baffle 122 to slide on the track 16 through the clamping plate 15, the right baffle 122 is connected with the upper part of the synchronous belt due to the lower connection of the left baffle 121 and the synchronous belt, and the movement of the left baffle 121 and the right baffle 122 is in equal distance and reverse through the coupling of the synchronous belt.

right shutters

121 and 122 in the open and closed states, respectively. When the left and

right shutters

121 and 122 are moved to the open and closed positions, the sensor 24 is triggered and the control system stops the motor. When the sensor fails or the control system fails, the limiting blocks 17 at the two motion limit ends of the track 16 play a limiting role.

Under the action of the mechanism, the motor forward and reverse rotation mechanism is switched between an opening state and a closing state.
