Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Hereinafter implement
Example is not limited to the scope of the present invention for illustrating the present invention.
Accompanying drawing 1-3 is referred to, present embodiment discloses a kind of towing mechanism 1 of truck, it includes bearing 2 and is hinged on institute
Trigger assembly 3, the peg component 4 on bearing 2 is stated, the trigger assembly 3 includes the rotating shaft 32 with triggering handle 31, is fixed on
Triggering block 33 in rotating shaft 32, the bearing 2 is provided with the reserved face for shelving the triggering block 33, and the triggering block 33 has
There is the free degree of the dorsad reserved face 32 rotations around the shaft；The peg component 4 includes the lever being hinged on the bearing 2
Type peg 41, is fixed with wedge-shaped catch 42 on the peg 41, taken by the wedge-shaped catch 42 and put in the triggering block 33
Side, makes the peg 41 incline and rest on the bearing 2 towards bearing side, realizes that the peg component 4 is being turned over
Roll over the spacing of direction of rotation.Specifically, taken by the wedge-shaped catch 42 when the peg 41 and put in the top of the triggering block 33
When, the peg 41 is obliquely rested on the bearing 2 towards bearing side, and one is intersected less than 90 ° with horizontal plane
Angle.
Based on above-mentioned technical characteristic, by the peg component 4 for designing level type, using triggering block 33 as the peg component
4 triggering devices for keeping flat rotary motion, when needing to keep flat peg component, it is only necessary to which operating personnel rotate triggering handle, touch
Sending out block 33 promotes wedge-shaped catch 42 to make peg component smooth rotation, it is ensured that the validity of the trigger action of trigger assembly, operation letter
It is single easy；By design peg on wedge-shaped catch 42 coordinate with the triggering block 33, make peg component turn down state when can
Firmly to lean against on bearing 2 by self gravitation, without being fixed by other attachment devices；The present invention's drags
Suspension mechanism is simple and reasonable, and retractable operation is easy, the trolley device that can be applied on production assembly line.
The peg 41 adopts level type structure, with two free ends, on the peg 41 rotary shaft is fixedly connected with
43, the rotary shaft 43 is fixed on bearing 2.The one end of the peg arranges link 44 or hook, in the present embodiment,
The peg adopts hanging ring structure, and the pin member or hook on the link 44 and other trucks coordinates the company realized between truck
Connect.The wedge-shaped catch 42 is arranged between rotary shaft 43 and link 44 or hook.By the other end of the peg 41
It is butted on the bearing 2, to realize that the peg component 4 is keeping flat the spacing of direction of rotation.Specifically, when the peg component
4 in flat condition when, the end of the peg 41 is butted on spacing to realize on the bearing 2.
Limited block 21 is provided with the bearing 2, is butted on the limited block 21 by the end of the peg 41, realized
The peg component 4 is keeping flat the spacing of direction of rotation.The end that the peg 41 offsets with the limited block 21 is connected with and subtracts
Shake device 45, the damping device 45 is arranged at the side that the end contacts with the limited block 21.The damping device

To ensure that the peg 41 can be inclined in the state of turnover towards bearing side, the triggering block 33 is set
Length less than horizontal range between the rotating shaft 32 and the rotary shaft 43.So that the triggering block 33 is in flat condition
When, it is between the rotating shaft 32 and the rotary shaft 43, in the horizontal direction without departing from outside the rotary shaft 43.
The triggering block 33 is block structure, it is preferred that the triggering block 33 is provided with fin, takes in order to the wedge-shaped catch 42 and puts
Above triggering block.The face contacted with the triggering block 33 of the wedge-shaped catch 42 is set to inclined-plane, to be further ensured that
The peg 41 can be inclined and rested on the bearing 2.
The bearing 2 is provided with the rotary shaft 43 of the rotating shaft 32 for installing the trigger assembly and the peg component
Installing hole 22.The bearing 2 also includes the extending bracket 23 for reinforcing the rotating shaft 32 of the trigger assembly.
Remain in advance that the through hole of horizontal adjusting bolt is installed on the limited block 21 of the bearing, the horizontal adjusting bolt
End offsets with the end of the peg 41.In the present embodiment, the end of the horizontal adjusting bolt and the end of the peg 41
The rubber sheet gasket that portion installs offsets.When the truck towing mechanism by long-term use or because on the bearing reserve described in
The installing hole of the rotary shaft 43 of peg component is excessive and when causing peg component to sink, adjustable horizontal adjustment bolt so as to
When rubber sheet gasket offsets, remain that peg is the level of state placement, facilitates towing mechanism normally to mount with other trucks.
Accompanying drawing 5 is referred to, is the sectional view of Section A-A in accompanying drawing 4, the towing mechanism for disclosing the truck is keeping flat shape
Structural representation under state.Now, inactive state of the triggering block 33 of the trigger assembly in horizontal positioned, the peg 41
In flat condition, the end for being provided with link of the peg 41 can be with other truck mountings, the other end of the peg 41
It is butted on the limited block 21 of the bearing, makes peg holding level.
Now, if desired the peg component 4 turned down, then prop up manually the end for being provided with link of peg 41 make its around
Rotary shaft rotates and leans against on bearing 2.
Accompanying drawing 6 is referred to, structural representation of the towing mechanism of the truck under turnover state is disclosed.Now, institute
State trigger assembly triggering block 33 it is static be held on the reserved face of bearing, the peg 41 towards bearing side incline simultaneously
Rested on the bearing 2 using self gravitation, the wedge-shaped catch 42 is taken and put in the top of the triggering block 33.
Now, if desired the peg component 4 kept flat, then stirring the triggering handle 31 of the trigger assembly makes described turning
Axle 32 is rotated, and drives the triggering block 33 dorsad reserved face 32 rotation around the shaft, the triggering block 33 promote take put
Wedge-shaped catch 42 thereon, makes wedge-shaped catch 42 that the rotary motion in opposite direction with the triggering block 33 to occur, so as to drive
State peg 41 and turn to flat condition around rotary shaft 43.Accompanying drawing 4 is referred to, is provided with the rotating shaft 32 of the trigger assembly 3 multiple
Position spring 34.The back-moving spring 34 is used to stir the triggering handle 31 of the trigger assembly rotates the rotating shaft 32
Afterwards, the trigger assembly 3 can automatically reset.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art come
Say, on the premise of without departing from the technology of the present invention principle, some improvement and replacement can also be made, these improve and replace also should
It is considered as protection scope of the present invention.
