Description

Technical Field

[0001] The utility model relates to the field of a head-jumping torque device, and more specifically, to a novel bidirectional head-jumping torque device. Background Art

[0002] The existing drive shafts on the market can transmit the power of the engine to the working parts under normal working conditions. However, due to the complexity of actual work, the working equipment can easily be stuck by stones or entangled by weeds, resulting in excessive torque. That is, when the torque is too large and the equipment encounters resistance exceeding the rated torque during work, it is easy to cause damage to the drive shaft and other equipment. The bidirectional jumping head torquer can disconnect the transmission connection and idle when the torque is too large.

[0003] However, in actual use, the existing bidirectional jumping head torquer mainly controls the torque of the bidirectional jumping head torquer by controlling the number of jumping heads and spring assemblies, but the number of bidirectional jumping head torquers of the same specification is fixed, and when the torque needs to be adjusted, it can only be adjusted by replacing the bidirectional jumping head torquer of different specifications, which has certain limitations when used. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a novel bidirectional jumping head type torque device. By increasing the length of the reset spring, when the jumping head is pressed into the inner groove, the reset spring will not be compressed to the limit, and has a certain adjustment range. At the same time, the baffle can be pushed outward by the adjusting component, and the baffle compresses the reset spring, thereby increasing the torque required for the jumping head to be pressed into the inner groove. Conversely, it drives the baffle to move inward, reducing the torque required for increasing the jumping head to be pressed into the inner groove, thereby adjusting the torque of the bidirectional jumping head type torque device, which is more practical.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a new type of bidirectional jumping head torque device, comprising:

[0006] A first body, wherein a horn fork for connection is fixedly mounted on one side of the first body, and an outer cover is fixedly mounted on the other side of the first body;

[0008] Preferably, the jumping head assembly includes an inner groove opened around the outer surface of the second body, a jumping head is arranged inside the inner groove, and the outer surface of one end of the jumping head is a curved surface, the inner wall of the outer cover is provided with a convex groove protruding outward at one end of the jumping head, one end of the jumping head is inserted into the convex groove, and the first body is transmitted by inserting the jumping head into the convex groove.

[0009] Preferably, a return spring is arranged inside the inner groove at the other end of the jumping head, and one end of the return spring is contact-connected with the jumping head. When the jumping head is pressed in, the return spring will be squeezed.

[0010] Preferably, the adjustment assembly includes a baffle arranged in the inner groove at the other end of the return spring, and a connecting rod is arranged on one side of the baffle, and the return spring is compressed by the baffle.

[0011] Preferably, a ring is provided at the inner center of the second body, connecting frames are provided at both ends of the connecting rod, and both ends of the connecting rod are movably connected to the connecting frames, and the connecting frames at both ends are respectively fixedly mounted on the outer surfaces of the baffle and the ring, and the ring and the baffle are connected through the connecting rod.

[0013] Technical effects and advantages of the utility model:

When the resistance is greater than the torque during the rotation process, the jumping head 22 will be pressed into the inner groove and the internal return spring 23 will be squeezed.

[0026] In a preferred embodiment, Figure 5As shown, the adjustment assembly includes a baffle 24 arranged in the inner groove at the other end of the reset spring 23, a connecting rod 28 is arranged on one side of the baffle 24, a collar 27 is arranged at the inner center of the second body 2, connecting frames 29 are arranged at both ends of the connecting rod 28, and both ends of the connecting rod 28 are movably connected to the connecting frames 29, and the connecting frames 29 at both ends are respectively fixedly mounted on the outer surfaces of the baffle 24 and the collar 27, driving the connecting rod 28 to push the baffle 24 outward, and the baffle 24 compresses the reset spring 23, thereby increasing the torque required for the jump head 22 to be pressed into the inner groove.
