Embodiment Construction

[0020] Such as Figure 7 As shown, the retractor includes parts such as a body 4, a rope 2, a shaft tube 1, a hook 5, and a ratchet 3. The shaft tube 1 is fixedly connected with the ratchet 3 and installed on the body 4 for winding the rope 2 . Hook 5 is at the two ends of the tractor. The rope fixing structure of the tractor is arranged on the shaft tube 1, and the inner end of the rope 2 is connected with the shaft tube 1 through the fixing device.

[0021] Figure 1 and figure 2 As shown, there is a positioning hole 11 on the shaft tube 1, and the inner end of the rope 2 is embedded in the positioning hole 11. In this embodiment, there is a head 21 at the inner end of the rope 2 . The head 21 is made of aluminum, and is fixedly connected with the inner end of the rope 2 . The size of the sealing head 21 is larger than the diameter of the positioning hole 11 . When the inner end of the rope 2 is inserted into the positioning hole 11, the rope 2 will not be detached from...

Abstract

The present invention relates to rope fixing structure for traction device in mechanism technology, and relates to tool for traction, binding and hoisting. The rope fixing structure is set on the rope winding axle tube, and the axle tube has one positioning hole for the inside end of rope to be embedded in and one notch extending from the positioning hole toward the rope winding direction. When the rope is wound onto the axle tube, the initial section is inside the notch. The rope fixing structure makes the rope wound to the axle tube without raised part and possess balanced stress, less breaking and long service life. The rope fixing structure is reasonable and practical.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a tool for pulling, binding or lifting. Background technique [0002] Tractors are often used when towing heavy loads, vehicles, or setting up tents. The structure of the tractor is as Figure 7 Shown, the middle part of tractor is body 4, and suspension hook 5 is arranged at two ends. A shaft tube 1 is arranged on the body, and a rope 2 connected with a suspension hook 5 is wound on the shaft tube 1 . When the tractor is in use, the rope 2 wound on the shaft tube 1 needs to be pulled out so as to hook a heavy object or a vehicle. [0003] Such as Figure 8 As shown, in the retractor of the existing structure, the inner end of the rope 2 is embedded in a positioning hole of the shaft tube 1 and is fixedly connected. After the inner end of the rope 2 comes out from the positioning hole, it needs to be bent at an angle greater than 90 degrees before it can be woun...
