Description

Technical Field

[0001] The present invention relates to the technical field of torque wrenches, and particularly to a torque wrench for adjusting the overtravel of a circuit breaker. Background Art

[0002] A torque wrench is a type of wrench. According to the power source, it can be divided into an electric torque wrench, a pneumatic torque wrench, a hydraulic torque wrench, and a manual torque wrench. The manual torque wrench can be divided into a preset type, a fixed value type, a dial type, a digital display type, a slipping type, a bending type, and a kilogram wrench. Most of the traditional ratchet torque wrenches have a single-direction tightening direction. When it is necessary to disassemble a bolt, the torque wrench needs to be removed and reinstalled so that the tightening direction of the torque wrench is opposite, which is time-consuming and laborious to use. Summary of the Invention

[0003] In view of this, to solve the above problems, the object of the present invention is to provide a torque wrench for adjusting the overtravel of a circuit breaker, including:

[0014] The present invention will be further described below in conjunction with the drawings and specific embodiments, but it is not intended to limit the present invention.

[0015] As Figures 1 to 3 shown, a torque wrench for adjusting the overtravel of a circuit breaker in a preferred embodiment is shown, including:

[0016] A holding body 1, a mounting portion 2, a ratchet wheel 3, an adjusting rod 4, an adjusting member, a driving member, and a sleeve 12. The mounting portion 2 is mounted at one end of the holding body 1. The mounting portion 2 has a mounting space. The ratchet wheel 3, the adjusting member, and the driving member are all mounted in the mounting space. One end of the adjusting rod 4 is mounted on the adjusting member. One end of the adjusting member and the driving member are rotatably mounted in the mounting space. The rotation axes of the adjusting member, the driving member, and the ratchet wheel 3 are coaxially arranged. The driving member is fixedly connected to the holding body 1. The holding body 1 operably drives the driving member to rotate. The driving member has a first hook body 5 and a second hook body 6. The adjusting member operably enables one end of the first hook body 5 or one end of the second hook body 6 to be in transmission connection with the ratchet wheel 3. One end of the sleeve 12 is mounted on the ratchet wheel 3.

[0017] During actual use, when the other end of the sleeve 12 is sleeved on a workpiece to be tightened, by adjusting the position of the adjusting member through the adjusting rod 4, one end of the first hook body 5 or one end of the second hook body 6 can be in transmission connection with the ratchet wheel 3. Specifically, when adjusting the adjusting rod 4 to make one end of the first hook body 5 in transmission connection with the ratchet wheel 3, the tightening direction of the ratchet wheel 3 can be made to face one direction, and then the workpiece to be tightened can be rotated in one direction to complete the installation of the workpiece to be tightened. When adjusting the adjusting rod 4 to make one end of the second hook body 6 in transmission connection with the ratchet wheel 3, the tightening direction of the ratchet wheel 3 can be made to face the other direction, and then the workpiece to be tightened can be rotated in the other direction to complete the disassembly of the workpiece to be tightened. Thus, it is not necessary to remove the sleeve 12 and reinstall it, which is convenient and fast.

[0018] Further, as a preferred embodiment, the adjusting member includes: a connecting piece 9 and a shielding piece 10. One end of the connecting piece 9 is rotatably mounted in the mounting space. One end of the adjusting rod 4 is mounted on the connecting piece 9. One end of the shielding piece 10 is perpendicularly mounted on the other end of the connecting piece 9. The shielding piece 10 operably shields the outer wall of the ratchet wheel 3. Further, during actual use, such as Figure 2As shown in the figure, when the shielding piece 10 shields one end of the first hook body 5, by holding the main body 1 to drive the mounting rod 7 to rotate counterclockwise on the paper surface, and then driving the driving rod 8 to rotate counterclockwise, so that the second hook body 6 rotates counterclockwise. Then, by holding the main body 1 to drive the mounting rod 7 to rotate clockwise on the paper surface, and then driving the driving rod 8 to rotate clockwise, so that the second hook body 6 rotates clockwise. At this time, one end of the second hook body 6 meshes with the outer wall of the ratchet wheel 3, thereby driving the ratchet wheel to rotate clockwise. When adjusting the shielding piece 10 to shield one end of the second hook body 6 through the adjusting rod 4, by holding the main body 1 to drive the mounting rod 7 to rotate clockwise and counterclockwise on the paper surface, and then driving the driving rod 8 to rotate clockwise, so that the first hook body 5 rotates clockwise. Then, by holding the main body 1 to drive the mounting rod 7 to rotate counterclockwise on the paper surface, and then driving the driving rod 8 to rotate counterclockwise, so that the first hook body 5 rotates counterclockwise. At this time, one end of the first hook body 5 meshes with the outer wall of the ratchet wheel 3, thereby driving the ratchet wheel 3 to rotate counterclockwise, and the screwing direction of the ratchet wheel 3 can be changed. Further, when the first hook body 5 rotates clockwise, one end of the first hook body 5 does not mesh with the outer wall of the ratchet wheel 3. When the first hook body 5 rotates counterclockwise, one end of the first hook body 5 meshes with the outer wall of the ratchet wheel 3. When the second hook body 6 rotates counterclockwise, one end of the second hook body 6 does not mesh with the outer wall of the ratchet wheel 3. When the second hook body 6 rotates clockwise, one end of the second hook body meshes with the outer wall of the ratchet wheel 3.

[0019] Further, as a preferred embodiment, the driving member further includes: a mounting rod 7 and a driving rod 8. One end of the mounting rod 7 is connected to one end of the driving rod 8. The other end of the mounting rod 7 is mounted on one end of the holding main body 1. The other ends of the first hook body 5 and the second hook body 6 are rotatably mounted on the other end of the driving rod 8. The shielding piece 10 can operably shield one end of the first hook body 5 or one end of the second hook body 6.

[0020] Further, as a preferred embodiment, the first hook body 5 extends in a first direction, the second hook body 6 extends in a second direction, and the first direction is opposite to the second direction.

[0021] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention accordingly.

[0022] The present invention further has the following implementation manners on the above basis:

[0023] In a further embodiment of the present invention, the mounting portion 2 has a limiting groove 11, and the other end of the adjusting rod 4 is disposed in the limiting groove 11.

[0024] The above are only the preferred embodiments of the present invention, and do not limit the implementation and protection scope of the present invention. For those skilled in the art, it should be realized that all the equivalent substitutions and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
