[0002] The clutch is usually installed between two shafts, and the clutch can control whether the power is transmitted between the two shafts. Common clutch mechanisms generally include clutches, which are generally installed between the automobile engine and the gearbox, such as common electromagnetic clutches, magnetic powder clutches, friction clutches, hydraulic clutches, etc. This type of clutch is generally large in shape and is not suitable for installation in a relatively small structure.

[0003] Chinese utility model patent with publication number CN1278055C discloses a clutch and a driving device having the clutch, which greatly reduces the size of the existing clutch and is suitable for installation in a small structure. However, the structure is too complicated and has many parts, resulting in high cost. Utility Model Content

[0004] Technical purpose: In order to overcome the deficiencies in the prior art, the utility model provides a clutch device.

[0005] Technical solution: To achieve the above purpose, the utility model discloses a clutch device, comprising:

[0006] A rotating disk, wherein the rotating disk is provided with a first pin shaft and a second pin shaft, wherein the first pin shaft and the second pin shaft are slidably connected along the radial direction of the rotating disk;

[0007] A first shaft, the first shaft is fixed relative to the turntable and rotates synchronously with the turntable;

[0008] A second shaft, wherein the first shaft and the second shaft are disposed on both sides of the rotating disk, one end of the second shaft extends into the rotating disk, and the first pin shaft slides radially along the rotating disk so that one end of the first pin shaft is inserted into the second shaft and the other end of the first pin shaft is retained in the rotating disk;

[0009] A push plate is connected to the rotating plate in a relatively sliding manner, and the sliding direction of the push plate is the same as the sliding direction of the first pin shaft or the second pin shaft; the push plate is provided with a locking hole for inserting the second pin shaft.

[0010] Preferably, it also includes a push rod for pushing the push plate to slide and a first limit switch for sensing the position of the push plate.

[0011] Preferably, the first pin shaft and the second pin shaft are arranged at an interval of 180° in the circumferential direction of the turntable; a first pin hole and a second pin hole are arranged on the turntable, the first pin shaft is slidably connected in the first pin hole, and the second pin shaft is slidably connected in the second pin hole.

[0012] Preferably, the first pin shaft includes a first shaft body and a second shaft body, the first shaft body is slidably connected in the first pin hole, and the first shaft body is sleeved with a first spring. Under the action of the first spring, the first pin shaft has a tendency to slide out of the first pin hole; the second shaft body is slidably connected to the first shaft body, and the second shaft body is sleeved with a second spring. Under the action of the second spring, the second shaft body has a tendency to slide out of the first shaft body.

[0013] Preferably, the second pin shaft is sleeved and connected with a third spring, and under the action of the third spring, the second pin shaft has a movement tendency to slide out of the second pin hole.

[0014] Preferably, the push plate is provided with a cam groove, and the ends of the first pin shaft and the second pin shaft are pressed against the side wall of the cam groove.

[0015] Preferably, the rotating disk is connected to a cam disk, and a second limit switch for sensing the rotation position of the cam disk is provided on one side of the cam disk.

[0016] The utility model has the following beneficial effects:

[0017] (1) The push plate is used to push the first pin shaft and the second pin shaft to move. When the push plate pushes the second pin shaft to disengage from the locking hole, one end of the second pin shaft will be inserted into the second shaft, so that the first shaft, the turntable and the second shaft rotate synchronously; when the push plate returns to its original position, the first pin shaft is disengaged from the second shaft, and one end of the second pin shaft will extend into the locking hole, so that the second shaft will not rotate synchronously with the first shaft and the turntable, thereby realizing the clutch function. The entire structure is simple and exquisite.

[0018] (2) When the first shaft and the second shaft are in a non-synchronous rotation state, the second shaft can rotate arbitrarily without affecting other components. The clutch device can be applied to a two-layer manhole cover, wherein the second shaft is arranged above the second-layer manhole cover. In this way, if non-staff members rotate the second shaft arbitrarily, it will not affect the first shaft and other devices, thereby preventing accidental damage.

[0019] (3) The clutch and locking states of the first shaft and the second shaft can be identified through the first limit switch and the second limit switch, which is more intelligent.

[0020] (4) The push rod can be driven by an electric control device such as a motor or an electromagnet, or by a mechanical device such as a key rotation, in a flexible and diverse manner. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 To Attachment Figure 7 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0030] A clutch device comprises a rotating disk 1, a first shaft 4, a second shaft 5, a push disk 6, a push rod 8, a first shell 18 and a second shell 19.

[0031] The first shell 18 and the second shell 19 are matched up and down to form a chamber, and the turntable 1 is arranged in the above-formed chamber. The first shaft 4 is rotatably connected to the first shell 18, and the second shaft 5 is rotatably connected to the second shell 19. The first shaft 4 and the second shaft 5 are disposed on both sides of the turntable 1. The tail end of the first shaft 4 extends into the chamber and is provided with a recess 20. The side where the turntable 1 is connected to the first shaft 4 is provided with a protrusion 21. The recess 20 is inserted into the protrusion 21 to relatively fix the first shaft 4 and the turntable 1 so that the first shaft 4 and the turntable 1 rotate synchronously. A limiting hole 24 is provided at one end of the second shaft 5, and the end of the second shaft 5 provided with the limiting hole 24 is inserted into the turntable 1. The turntable 1 is connected with a first pin 2, and the first pin 2 can slide along the radial direction of the turntable 1. When one end of the first pin shaft 2 is inserted into the second shaft 5 and the other end of the second pin shaft 3 remains in the turntable 1, the second shaft 5 rotates synchronously with the turntable 1 and the first shaft 4; when the first pin shaft 2 is completely retained in the turntable 1, when the turntable 1 and the first shaft 4 rotate, the second shaft 5 does not rotate synchronously. A cam groove 15 is provided at the center of the push plate 6, and a component consisting of the turntable 1, the first shaft 4 and the second shaft 5 passes through the cam groove 15. The push plate 6 can slide in the radial direction of the turntable 1, that is, in the same sliding direction as the first pin shaft 2. When the push plate 6 moves, it can push the first pin shaft 2 to move, thereby controlling whether the second shaft 5 can rotate simultaneously with the first shaft 4 and the turntable 1.

[0032] A push rod 8 and a first limit switch 9 are respectively provided on both sides of the push plate 6. The first limit switch 9 is used as a limit sensor for detecting the position of the push plate 6. The push rod 8 is used as a power component to push the push plate 6 to move. The driving method of the push rod 8 is not limited here. For example, an electric control device 25 such as a motor or an electromagnet can be used to drive the push rod 8 to move back and forth, or a physical driving structure such as a key rotation can be used at the end of the push rod 8. The turntable 1 is provided with a first pin hole 10 for accommodating the first pin shaft 2, and the first pin shaft 2 is slidably connected to the first pin hole 10. Specifically, the first pin shaft 2 includes a first shaft body 22 and a second shaft body 23. The first shaft body 22 is slidably connected to the first pin hole 10. The first shaft body 22 is sleeved with a first spring 12. When there is no external force, the first shaft body 22 has a tendency to slide out of the first pin hole 10 under the action of the first spring 12. The second shaft body 23 is slidably connected to the first shaft body 22. The second shaft body 23 is sleeved with a second spring 13. Under the action of the second spring 13, the second shaft body 23 has a tendency to slide out of the first shaft body 22. When the thrust of the push rod 8 disappears, the push plate 6 is pushed to return to its initial position under the action of the first spring 12 and the second spring 13.

[0033] The turntable 1 is also connected with a second pin shaft 3, and the first pin shaft 2 and the second pin shaft 3 are arranged at an interval of 180° in the circumferential direction of the turntable 1. Correspondingly, a second pin hole 11 is also arranged on the turntable 1, and the second pin shaft 3 is slidably connected in the second pin shaft 3. The second pin shaft 3 is sleeved and connected with a third spring 14, and under the action of the third spring 14, the second pin shaft 3 has a movement tendency to slide out of the second pin hole 11. The push plate 6 is provided with a locking hole 7 for inserting the second pin shaft 3. After one end of the second pin shaft 3 extends into the locking hole 7, the first shaft 4, the turntable 1 and the push plate 6 are relatively fixed; when one end of the second pin shaft 3 is retracted into the locking hole 7 of the turntable 1, the first shaft 4 and the turntable 1 can rotate relative to the push plate 6.

[0034] The ends of the first pin shaft 2 and the second pin shaft 3 are pressed against the side wall of the cam groove 15. Figure 2 Under the action of the cam groove 15, the second pin shaft 3 can only rotate 90° counterclockwise. The second shaft 5 is connected to a cam plate 16, and a second limit switch 17 for sensing the rotation position of the cam plate 16 is arranged on one side of the cam plate 16.

[0035] The purpose of the device is to provide a clutch device which can control whether the first shaft 4 and the second shaft 5 can rotate synchronously, which is mainly achieved by using a push plate 6 to push the first pin shaft 2 and the second pin shaft 3 to slide.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
