Detailed Description

A winding type height-adjusting bus handle comprises a ring-cylindrical pull ring 1, an annular ring cover surface 2 is arranged on the outer ring of the upper side of the pull ring 1, an annular lock catch track 3 is arranged on the inner ring of the ring cover surface 2, an annular belt groove 4 is arranged on the side surface of the pull ring 1 along the circumference of a ring, a rope belt fixing groove 5 is arranged on the surface of the belt groove 4, one end of a rope belt 7 is fixed on the fixing groove 5 through a clamping plate 6 on the rope belt fixing groove 5, the rope belt 7 is laid on the belt groove 4 and penetrates through a lock catch 8 arranged on the lock catch track 3 to extend out of the pull ring 1 and be connected to a fastener 9, a rotary ring 11 with a lock catch hole 10 is arranged on the side surface of the ring cover 2 on the inner side, an annular ring cover 12 is arranged on the outer side, an inner side cover of the ring cover 12 is arranged on the upper side of the rotary ring 11, the outer side is fixedly connected to the ring cover surface 2, the cross, the protrusion of the rear of the track block 13 after being bent by 90 degrees is a positioning plate 14, the hook of the rear of the positioning plate 14 after being bent by 90 degrees is a rope belt hook 15, a pin hole 16 is arranged on the side surface of the track block 13, and a positioning pin 17 is arranged on the pin hole 16.

In order to realize the purpose of locking the belt 7 and seal the rotating ring 11 on the ring cover surface 2, the ring cover 12 comprises a cover ring 201 and a seal ring 202, wherein the cover ring 201 is provided with 3-10 screw holes along the circumference, the seal ring 202 is fixedly connected to the inner side of the cover ring 201, and the seal ring 202 is provided with a plurality of lock holes 203 along the circumference.

In order to realize the multi-level height adjustment of the bus pull ring, the number of the lock holes 203 is 3-20.

In order to prevent the lock catch 8 from falling off and limit the lock catch 8 to a certain range of movement, the lock catch track 3 is a closed annular space 101 formed by the pull ring 1 and the rotating ring 11, and the track block 13 extends into the closed annular space 101 through the lock catch hole 10, and the pin hole 16 is located in the closed annular space.

In order to press or pull the lock catch 8 to have a certain movement space, the depth of the lock catch rail 3 is larger than the sum of the distance from the pin hole 16 to the bottom of the rail block 13 and the depth of the lock hole 203.
