The specific embodiment

Below in conjunction with accompanying drawing, the utility model is specifically described (but be not to scope of the present utility model restriction) by embodiment.

As Fig. 1, Fig. 2, shown in Figure 3 is the structure and the connected mode of a kind of specific embodiment of the present utility model, the utility model, comprise motor (1), shell (8), it is characterized in that motor (1) being installed in the bottom of shell (8), one end of motor (1) is electrically connected with electronic control circuit (2), the other end is connected with axis of rotation (3), axis of rotation (3) and gear train (4) engagement, compression spring (5) will be pressed on the output shaft (7) of resisting force sheet (6) on the gear train (4), make gear train (4) and output shaft (7) break-in, output shaft (7) upper end is by mother pressure regulation sieve (30), fixedly connected with shell (8) by bearing (32) and pass shell (8) in the lower end, one end of resisting force sheet (6) is equipped with limit switch bar (10), limit switch bar (10) is connected with limit switch 1 (9), and limit switch 1 (9) is fixed on the shell (8).

With reference to Fig. 1, shown in Figure 3, electronic control circuit (2) is electrically connected and is formed by limit switch bar (10), limit switch 1 (9), limit switch 2 (11), relay J 13, relay J 14, relay J 15 and contact J13-1, J13-2, J13-3, J13-4, J14-3, J14-1, J14-2, J14-4, J15-1, push switch 1 (12), push switch 2 (16), tunable capacitor C, resistance R, and connected mode as shown in Figure 3.

Can come adjustment doors to open and close the size of angle by adjusting the position of limit switch 1 (9), limit switch 2 (11).And the size that the size of regulating tunable capacitor C capacity can be regulated big gate delay lockup.

Can pass through to adjust the elasticity of mother sieve (30), adjustment compression spring (5), thereby regulate the size of resisting force sheet (6) with the frictional force of gear train (4).When hand push widens, because being rotated axle (3), blocks gear train (4), and thrust is during greater than frictional force, and output shaft (3) produces with gear train (4) and separates, and output shaft (7) rotates, the switch of drive.

The utility model can be realized the full-automatic switch door, also can take the manual switch door.

The operating principle of full-automatic switch door is: with the K switch closure; press the button switch 1 (12); press button 1 (12) closure; power supply A is through press button 1 (12); normally closed interlock (11-1) through limit switch 2 (11); arrive relay J 13 through relay J 14 constant close contact J14-2; relay J 13 energisings; constant open contact J13-3; J13-4; the J13-1 closing of contact; J13-2 disconnects (protection power supply short circuit; be the double relay closure) electrical power; the motor shaft forward rotation makes axis of rotation (3) rotate the rotation that has driven gear train (4), and compression spring (5) will be pressed on the output shaft of resisting force sheet (6) on the gear train (4); when gear train (4) rotates; driven the rotation of output shaft (7), the rotation of output shaft (7) has driven the rotation of door-hinge by mechanical connection, and the gate is opened.When door forwards certain angle to, limit switch bar (10) is pushed down limit switch 2 (11), cause the constant close contact of limit switch 2 (11) to disconnect, constant open contact (11-2) closure of limit switch 2 (11), relay J 13 outages, the J13-1 contact disconnects, the J13-2 closure, the motor stall, the gate is opened and is finished.At this moment power supply is through K switch, the ration the power supply constant open contact of switch 2 (11), after resistance R, tunable capacitor C is charged, after the time-delay, relay J 15 energisings, constant open contact J15-1 closure, power supply is through J15-1, limit switch 1 (9), J13-2, to relay J 14 energisings, constant open contact J14-3, J14-4, the J14-1 closure, J14-2 disconnects, the motor counter-rotating, the motor shaft backward rotation makes axis of rotation (3) rotate the rotation that has driven gear train (4), and compression spring (5) will be pressed on the output shaft of resisting force sheet (6) on the gear train (4), when gear train (4) rotates, driven the rotation of output shaft (7), the rotation of output shaft (7) has driven the rotation of door-hinge by mechanical connection, and the gate is closed.When door was closed, limit switch bar (10) was pushed down limit switch 1 (9), caused the constant close contact of limit switch 1 (9) to disconnect, relay J 14 outages, and J14-3, J14-4, J14-1 contact disconnect the J14-2 closing of contact, motor stall.And when limit switch bar (10) was pushed down limit switch 1 (9), limit switch bar (10) had left limit switch 2 (11), and limit switch 2 (11) constant close contact closures, constant open contact disconnect, and perform the preparation of opening door next time.

Semi-automatic operating principle of opening the door is: K switch is disconnected, when opening the door, press the button switch 1 (12), power supply is through the normally closed interlock (11-1) of press button 1 (12) through limit switch 2 (11), through relay J 14 normally closed interlock J14-2, to relay J 13, relay J 13 energisings, J13-3, J13-4, the J13-1 closing of contact, J13-2 disconnects, electrical power, the motor shaft forward rotation, make axis of rotation (3) rotate the rotation that has driven gear train (4), compression spring (5) will be pressed on the output shaft of resisting force sheet (6) on the gear train (4), when gear train (4) rotates, drive the rotation of output shaft (7), the rotation of output shaft (7) has driven the rotation of door-hinge by mechanical connection, and the gate is opened.When door forwarded certain angle to, limit switch bar (10) was pushed down limit switch 2 (11), caused constant close contact (11-1) disconnection, constant open contact (11-2) closure of limit switch 2 (11), J13, J13-1 contact disconnect, the J13-2 closure, the motor stall, the gate is opened and is finished.

Semi-automatic operating principle of closing the door is, K switch is disconnected, press the button switch 2 (16), power supply is through the contact of press button 2 (16) through limit switch 1 (9), arrive relay J 14 through the J13-2 contact, the motor shaft backward rotation, make axis of rotation (3) rotate the rotation that has driven gear train (4), compression spring (5) will be pressed on the output shaft axle of resisting force sheet (6) on the gear train (4), when gear train (4) rotates, driven the rotation of output shaft (7), the rotation of output shaft (7) has driven the rotation of door-hinge by mechanical connection, and the gate is closed.
