Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
A kind of hoisting trolley traction device as shown in FIG. 1 to FIG. 3, including connecting rod 1, the connecting rod 1 are symmetrical arranged two
It is a, slot 11 is set on the inside of the connecting rod 1, is provided with motion bar 12,12 tail portion of motion bar and slot in the slot 11
The first spring 13 is connected between 11 inner walls, and second spring 14 is connected between two sides motion bar 12, is provided with hook on the outside of the connecting rod 1
Body 2, the coupler body 2 include hook-holding part 21, locking part 22, and the locking part 22 is articulated with the tail portion of hook-holding part 21, and the hook is held
21 end of portion is fixedly installed block 23, and convex block 24 is fixedly installed on the inside of the block 23, and the locking part 22 passes through overturning
Cooperate the open end that can close hook-holding part 21, one spacer pin 3 of grafting, institute between the block 23 and locking part 22 with convex block 24
It states block 23 and a through-hole 4 is arranged in 3 junction of spacer pin, 4 inner wall of through-hole is provided with flange 41, is arranged on the flange 41
There is card slot 42, card slot 42 is corresponded on the outside of the spacer pin 3, fixture block 31 is fixedly installed, the fixture block 31 cooperates with card slot 42, described
One spin-block 32 is set on spacer pin 3.
Furthermore, limited block 15 is arranged in 12 end of motion bar, corresponds to limited block 15 on the outside of the slot 11 and sets
It is equipped with block edge 16, the block edge 16 cooperates with limited block 15.
Furthermore, the limited block 15 is slidably matched with slot 11.
Furthermore, first spring 13 is damping spring.
Furthermore, the second spring 14 is compressed spring.
Furthermore, the locking part 22 is provided with reset spring 25 with 21 hinged place of hook-holding part.
Furthermore, the reset spring 25 is torsional spring.
Furthermore, the fixture block 31, card slot 42 are correspondingly arranged two groups.
Working principle: in use, user by the coupler body 2 in the outside of two end link 1 respectively with towing vehicle and hoisting trolley
Vehicle frame connection.
Firstly, by 32 turn spacer pin 3 of spin-block, so that the fixture block 31 in 3 outside of spacer pin is from the card slot 42 on flange 41
Interior back-out, settable clamp pad in card slot 42, to increase its clamping force between fixture block 31, so that fixture block 31 can not be easily
