Description

Technical Field

[0001] The utility model relates to the technical field of conversion heads, in particular to a ratchet conversion head. Background Art

[0002] The ratchet adapter is part of a torque wrench and is used for one-way tightening, eliminating the need to lift and reposition the wrench after each rotation. The ratchet adapter works by combining a ratchet and pawl to achieve one-way tightening. When the rocker swings counterclockwise, the pawl engages the ratchet's teeth, causing the ratchet to rotate in the same direction. When the rocker swings clockwise, the pawl slides over the ratchet, stopping it. This way, while the rocker swings back and forth continuously, the ratchet performs intermittent, one-way motion.

[0003] In existing ratchet adapters, when the pawl engages the ratchet's tooth groove to drive the ratchet, friction occurs between the teeth, causing wear. Furthermore, after prolonged use, the ratchet mechanism becomes more susceptible to wear due to the constant meshing and sliding of the teeth. Conventionally, lubricant is added to reduce direct friction, but due to the compact structure of the ratchet adapter, adding lubricant is cumbersome, affecting work efficiency. Utility Model Content

[0004] The utility model aims to provide a ratchet conversion head which is convenient for adding lubricating oil to reduce wear.

[0014] The present invention will be described in further detail below with reference to the accompanying drawings.

[0015] A ratchet adapter includes a mounting rod 1 with a hexagonal socket at its lower end and a platform 2 at its upper end. A ratchet is rotatably mounted in the middle of the platform 2, with spring-loaded pawls located on either side. The platform 2 is surrounded by an annular wall 4, with a sealed oil pipe 5 located on its inner wall. An oil filling hole 6 is provided in the annular wall 4, and a rubber seal 12 is provided on the oil filling hole 6 to prevent oil leakage when the tool is used after lubricating the tool.

[0016] An extension pipe 7 extending vertically downward is provided below the oil pipe 5 .

[0017] An arc-shaped push rod 8 is provided in the oil pipe 5. The cross section of the oil pipe 5 is circular, and the cross section of the push rod 8 is also circular. In addition, a rubber block 11 is provided at the front end of the push rod 8, so that the push rod 8 pushes the lubricating oil in the oil pipe 5 more tightly and stably.

[0018] Annular wall 4 is provided with a transverse groove 9. An extension rod 10 is provided at the rear end of push rod 8, extending out of transverse groove 9. Two extension rods 10 are provided, with an arc-shaped connecting rod 13 interposed between them. Connecting rod 13 is provided with a shifting lever 14, which facilitates shifting, thereby simultaneously pushing push rods 8 in both oil pipes 5.

[0019] The annular wall 4 is provided with a groove 15, and the connecting rod 13 is embedded in the groove 15. By embedding the connecting rod 13 in the groove 15, the obstruction caused when using the tool can be reduced, and only a shifting rod 14 is left outside.

[0020] When lubricating oil needs to be added, the lever 14 can be toggled to squeeze the oil stored in the oil pipe 5 out of the extension pipe 7, making it easier to add lubricating oil.

[0021] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
