【Detailed ways】

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Fig. 1, the utility model comprises a clutch cover 1, a square shaft positioning block 2, a positioning pin spring 3, a square shaft positioning pin 4, a positioning block pin 5, a toggle block 6, a rotating arm 7, a driving mechanism and a clutch seat 16; Wherein the inner ring 61 of the toggle block 6 is sleeved on the outer ring 21 of the square shaft positioning block 2, and the outer ring 21 of the square shaft positioning block 2 is provided with a hole 22 along the radial direction, and the position corresponding to the hole 22 is along the radial direction on the toggle block. There is also a hole 63 through the inner ring 61 and the outer ring 62 of the toggle block; the square shaft positioning pin 4 is placed in the hole 22, the positioning block pin 5 is placed in the hole 63, and one end of the square shaft positioning pin 4 withstands the positioning Block pin 5, the other end withstands the positioning pin spring 3 placed in the hole 22; one end of the positioning block pin 5 withstands the square shaft positioning pin 4, and the other end withstands the middle section of the rotating arm 7; one end of the rotating arm 7 Fixed on the clutch seat 16, the fixing method can be: a sleeve 72 is set on this end of the rotating arm 7, a positioning shaft 15 is established at a corresponding position on the clutch seat 16, and the sleeve 72 is sleeved on the position of the positioning shaft 15. method to fix, of course, this fixation is only relatively fixed, because the rotating arm 7 can rotate around the positioning shaft 15; the other end of the rotating arm 7 is connected to the drive mechanism, and the specific connection method can be that a hole 71, one foot 121 of the gear spring is placed on the motor worm 10, and the other foot 122 is inserted into the hole 71. A boss 23 is arranged on the square shaft positioning block 2 , and a stopper 64 is arranged on the toggle block 6 , and the stopper 64 cooperates with the boss 23 for transmission. The stopper can also be composed of a boss 66 and a positioning pin 67 thereon, and at this time, the boss 23 and the positioning pin 67 cooperate to drive.

The driving mechanism in the utility model comprises a motor seat cover 8, a motor 9, a motor worm 10, an axle sleeve 11, a gear spring 12, a spring shaft 13 and a motor seat bottom 14, and the gear spring 12 is set on the clutch seat 16 On the spring shaft 13 of the gear spring 12, one foot 121 of the gear spring 12 is placed on the motor worm 10, and the other foot 122 is inserted into the hole 71 at one end of the rotating arm 7, and the bushing 11 is placed above the gear spring 12 and sleeved on the spring shaft 13 on. In order to fix the motor 9, the motor 9 is placed in the motor seat cover 8 and the motor seat bottom 14. In order to prevent the gear spring 12 from slipping out of the motor worm 10, put a sleeve 11 on the gear spring 12 to fix the gear spring. 12.

The utility model can be designed as a clutch device suitable for left-opening or right-opening, as shown in Figure 2, the stopper of the toggle block 6 is placed on the left side of the boss 23, which is suitable for the situation of left-opening door; the stopper of the toggle block is placed on the boss On the right side of the stage, it is suitable for the case of right-opening door.

During specific operation, after power on, the motor 9 rotates forward, and the pin 121 of the motor worm 10 pushes the gear spring to move outwards. Due to the transmission of the power of the gear spring, the pin 122 also moves outwards, thereby driving the rotating arm 7 to rotate counterclockwise. The middle position of rotating arm 7 unclamps positioning block pin 5, and positioning block pin 5 and square axis positioning pin 4 move outwards under the effect of spring. At this time, the square shaft positioning pin 4 is inserted in the hole 22 and the hole 63 at the same time, so that the outer ring 21 of the square shaft positioning block 2 and the inner ring 61 of the toggle block 6 are linked, and at this time, the clutch device is "closed". " state, that is, the unlocked state; when the clutch device is in the "closed" state, the handle 17 is rotated, and the handle 17 drives the toggle block 6 to rotate through the handle card position 66, because the toggle block 6 is in contact with the square shaft positioning block 2 At this time, it is in a linkage state, so it drives the square shaft positioning block 2 to rotate together, thereby unlocking; when the motor 9 reverses, the motor worm 10 drives the gear spring 12 to move inward, thereby driving the rotating arm 7 to move clockwise, and the rotating arm 7 The middle position of the positioning block moves inward against the positioning block pin 5, and the positioning block pin 5 moves inward against the square shaft positioning pin 4. When the square shaft positioning pin 4 is pushed away from the inner ring 61 of the toggle block 6, the positioning block The pin is only inserted in the hole 63, the square shaft positioning pin is only inserted in the hole 22, the outer ring 21 of the square shaft positioning block 2 is separated from the inner ring 61 of the toggle block 6, and the "off" of the clutch device is realized. state, that is, the locked state. When the clutch is in the "off" state, the handle 17 is rotated, and the handle 17 drives the toggle block 6 to rotate. Since the toggle block 6 and the square shaft positioning block 2 are in a non-linkage state at this time, the toggle block cannot drive the square shaft. The positioning block rotates, so the lock cannot be unlocked. But the square tongue is not locked. At this time, the handle is lifted instead, and the handle drives the toggle block 6 to rotate. Since the square shaft positioning block 2 and the toggle block 6 are respectively provided with a boss 23 and a stopper 64, the toggle When the block 64 on the block 6 moves to the boss 23 on the square shaft positioning block 2, it is blocked. When the toggle block 6 continues to rotate, it will drive the square shaft positioning block 2 to rotate together, so that the square tongue is locked. If the square shaft The positioning block 2 is also connected with the heaven and earth lock bolt, and then the heaven and earth lock is locked simultaneously. In addition, in the locked state, the lock head assembly can be rotated with a key, and the lock head assembly drives the square shaft connecting piece 25, thereby driving the square shaft positioning block 2 to rotate and unlock.

The clutch device of the utility model can be used in various electronic locks, such as password locks, fingerprint locks, magnetic card locks and the like.
