Toothed structure of ratchet wrench

The creation system is related to the tooth structure of the ratchet wrench, in particular, the ratchet wrench has a first groove and a second groove, so that the two-way ratchet wrench and the one-way ratchet wrench can be shared.

As we have previously known, the tooth structure of the conventional ratchet wrench, please refer to the fifteenth figure, which is a top view of a conventional two-way ratchet wrench, the tooth structure is: a tooth 60, the tooth 60 side The occlusal tooth 61 is provided with a center line 611, and the occlusal tooth 61 is connected with a toothed arc 612. The toothing 60 is provided with a first groove 62 on the other side, and the first groove The 62 series alignment center line 611, the steering control structure of the ratchet wrench, such as the dial structure, controls the first groove 62, so that the tooth 60 is displaced to the left and right to control the positive and negative rotation of the ratchet wrench, which is a two-way The basic structure of the ratchet wrench tooth 60.

Please refer to the sixteenth figure, which is a top view of a tooth made of a one-way ratchet wrench; a tooth 70, which is provided with a bite 71 on the side of the tooth 70, and the bite 71 is provided with a center line 711. The occlusal teeth 71 are connected with a toothed arc 712. The toothing 70 is provided with a first groove 72 on the other side. The first groove 72 is offset from the center line 711, and the tooth 70 can only be rotated clockwise. Counterclockwise Retracted as a one-way ratchet wrench, this is the basic structure of the one-way ratchet wrench.

However, the two-way tooth 60 structure and the one-way tooth 70 structure are missing: the two-way ratchet wrench of the fifteenth figure is made of different sizes for the operator to rotate and rotate, each size The screwing parts of the same size need to be used to make the sleeve 60, such as 19mm, 18mm. . . The two-way ratchet wrench of the same specification needs to use the same size of the tooth 60 to fit the rotation. Similarly, the one-way ratchet wrench 70 shown in the sixteenth figure also needs to be used for each size of the screw. The teeth 70 of the same size can be fitted and rotated, that is, each size requires two-way tooth 60 and one-way tooth 70. Two different tooth-making structures are provided for the two-way ratchet wrench and the one-way ratchet wrench. The components are required, and all the sizes are at least twenty. The two-way tooth 60 has more than twenty kinds, and the one-way tooth 70 also needs twenty kinds. The two-way tooth 60 and The one-way tooth 70 system has a considerable cost.

In view of the above-mentioned conventional ratchet wrench's tooth structure, the creator has been researching and developing through years of experience in related industries, and finally has a ratchet wrench's tooth structure.

The new problem to be solved: the two-way ratchet wrench and the one-way ratchet wrench can not be shared. The conventional system manufactures two kinds of tooth structure and increases the cost of the tooth making. The ratchet wrench of the present invention has the first tooth system. a groove and a second groove enable the bidirectional ratchet wrench and the one-way ratchet wrench to be made Share.

The technical method for solving the problem is a tooth-making structure of a ratchet wrench, which comprises: a toothing, the front side of the toothing is provided with a plurality of engaging teeth, and a plurality of teeth are arranged in the middle of the plurality of teeth, the plurality of teeth are engaged At least one side of the tooth is provided with a second tooth portion, wherein each of the bite teeth has a curved surface shape, and the tooth valley has a concave edge shape, and the tooth system is provided with a center line, and the first tooth portion is Each arc surface is connected to a first arc, the center of the first arc is on the center line, and each arc surface of the second tooth portion is connected to a second arc, and the second tooth portion is close to the first tooth. The distance between the tooth of the part and the first arc is a first distance, and the tooth is provided with a first groove away from the bite tooth, the first groove is opposite to the center line and the first tooth part, and the tooth is away from the tooth The occlusal teeth are provided with a second groove, which is disposed beside the first groove, and the second groove is not aligned with the center line.

Compared with the effect of the prior art: the ratcheting wrench has a bite structure, a first groove and a second groove, so that the tooth can be set in the one-way and two-way ratchet regardless of how the tooth changes its appearance. In the wrench, the same size one-way and two-way ratchet wrench uses the same tooth. The tooth tip of each of the teeth of the tooth is curved, and the valley is concave-shaped, which avoids each bite hitting each valley of the ratchet portion of the ratchet. There is a large tolerance between the ratchet portion and the occlusal tooth, and the concave edge is accommodated for each tooth tip of the ratchet portion, and each tooth tip of the ratchet portion can avoid wear when the tooth is rotated. When the tooth is retracted, the factor of affecting the tooth removal between the ratchet portion and the engaging tooth is at the second tooth portion, and the second tooth portion is coupled with the first distance and the second distance, so that the second tooth portion and the ratchet portion are Have a larger spacing, and increase the retraction smoothly Sex.
