Example 1

Referring to fig. 1 to 4, an unhooking prevention device according to an embodiment of the present invention is shown, and has the following specific structure.

The embodiment of the application provides an mousing-hook device, including the guide arm 1 of being connected with lifting hook shank 501 and the sleeve 2 that aligns with lifting hook prong 502, guide arm 1 is located to the sleeve 2 cover, and guide arm 1 is provided with locating pin 3, and sleeve 2 is equipped with the guide way 201 from the top downwardly extending, and guide way 201 is connected with the screens groove 202 of restriction locating pin 3. Combine fig. 1 and fig. 2 to show, the utility model discloses an mousing-hook device mainly comprises guide arm 1 and sleeve 2 two parts, and guide arm 1 and sleeve 2's appearance is cylindricly, and guide arm 1's top and lifting hook shank 501 fixed welding (perhaps swing joint), and sleeve 2's last port is inserted from sleeve 1's bottom to guide arm 1, and sleeve 2 can slide from top to bottom along guide arm 1, and the extending direction of sleeve 2 lower extreme aligns with lifting hook prong 502 for can wrap lifting hook prong 502 after sleeve 2 glides.

Referring to fig. 2, one end of the positioning pin 3 is welded to the side wall of the guide rod 1, and when the guide rod 1 is vertically placed, the other end of the positioning pin 3 horizontally extends outward. The guide groove 201 vertically extends downwards from the top end of the sleeve 2, the right end of the clamping groove 202 is communicated with the lower end of the guide groove 201, the left end of the clamping groove 202 horizontally extends leftwards, and the overall appearance of the guide groove 201 and the clamping groove 202 is in an L shape.

During the in-service use, mousing-hook device installs on the couple, when needing to embolia or take the rope operation, slides sleeve 2 on, and locating pin 3 slides down along guide way 201, and forward rotation sleeve 2 when pending locating pin 3 slides to the bottom of guide way 201 lets locating pin 3 slide along screens groove 202, and the left end that slides to screens groove 202 is reached to locating pin 3. At this moment, the clamping groove 202 limits the positioning pin 3, so that the sleeve 2 is prevented from automatically sliding downwards, a gap is reserved between the lower end of the sleeve 2 and the hook point 502 of the lifting hook, and the rope can be conveniently sleeved in or picked up. Rope registrates or picks the back that finishes, reverse rotatory sleeve 2, let locating pin 3 slide along the position clamping groove 202 is right-hand, until locating pin 3 slide to the right-hand member of position clamping groove 202 (the bottom of guide way 201 promptly), sleeve 2 is automatic gliding under the action of gravity, locating pin 3 slides upwards along guide way 201, lifting hook prong 502 is covered to the lower extreme of sleeve 2, lifting hook prong 502 part stretches into in sleeve 2, sleeve 2 and lifting hook prong 502 are not keeping the clearance, rope slippage when avoiding the operation of hoisting, the security is very high.
