Abstract
A kind of trailer link mechanism, comprise draft arm, be fixed on dolly one end side arm, be fixed on the tailstock of the dolly other end, described draft arm two ends are respectively at side arm and tailstock active link, described tailstock and draft arm are detachable, described side arm comprises left front and right front, and left front is arranged with waist hole with right front, and Ke Yanyao hole, described draft arm end moves up and down, while being positioned at upper end, waist hole, draft arm can be around the rotation of upper end, waist hole, and while being positioned at lower end, waist hole, draft arm is fixing non-rotatable.The beneficial effects of the utility model: the utility model is simple in structure, are used safety, easy to operate simple, can save parking space simultaneously.
Description
Technical field
The utility model relates to transport field, is specifically related to a kind of trailer link mechanism.
Background technology
At present, in fields such as factory, warehouse, logistics centres, materials inside turnover is more and more frequent, for improving conveying efficiency, conventionally the dolly of many loadings is linked together, with power actuated vehicle traction transportation.This device is exactly the mechanism for loading dolly is linked together.Common on-link mode (OLM) has the danger of accidental, very high to transport routes requirement, uses inconvenience, also takes up room simultaneously.
Utility model content
The utility model provides a kind of use safety, simple to operate, saves the trailer link mechanism of parking space.
Solve the problems of the technologies described above the technical scheme of employing: a kind of trailer link mechanism, comprise draft arm, be fixed on the side arm of dolly one end, be fixed on the tailstock of the dolly other end, described draft arm one end is provided with annulus, the other end is provided with cross bar, annulus detachably links with tailstock, described side arm comprises left front and right front, left front is arranged with waist hole with right front, cross bar two ends embed in waist hole, when draft arm vertical-horizontal direction and annulus one end are positioned at top, cross bar can slide up and down along waist hole, when cross bar is positioned at waist hole epimere, draft arm can rotate around cross bar axle center, when cross bar is positioned at waist hole hypomere, draft arm is fixing not rotatable.
As optimization: described tailstock comprises support body, and support body is provided with locking mechanism, described locking mechanism comprises around the swivel pin of left bearing and right bearing rotation, the retracing spring resetting for swivel pin, for swivel pin being carried out to spacing He Xiayao hole, upper waist hole.
As optimization: described left front and right front is provided with baffle plate.
The beneficial effects of the utility model: the utility model is simple in structure, are used safety, easy to operate simple, can save parking space simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
In figure: 1, support body, 2, draft arm, 31, left front, 32, right front, 4, annulus, 5, cross bar, 6, waist hole, 7, swivel pin, 8, retracing spring, 9, upper waist hole, 10, lower waist hole, 11, left bearing, 12, right bearing, 13, baffle plate.
The specific embodiment
As Fig. 1, shown in 2: a kind of trailer link mechanism, comprise draft arm 2, be fixed on the side arm of dolly one end, be fixed on the tailstock of the dolly other end, described draft arm 2 one end are provided with annulus 4, the other end is provided with cross bar 5, annulus 4 detachably links with tailstock, described side arm comprises left front 31 and right front 32, be arranged with waist hole 6 with right front 32 for left front 31, cross bar 5 two ends embed in waist hole 6, when draft arm 2 vertical-horizontal directions and annulus 4 one end are positioned at top, cross bar 5 can slide up and down along waist hole 6, when cross bar 5 is positioned at waist hole 6 epimere, draft arm 2 can be around cross bar 5 axle center rotations, when cross bar 5 is positioned at waist hole 6 hypomere, draft arm 2 is fixing not rotatable,
Described tailstock comprises support body 1, support body 1 is provided with locking mechanism, described locking mechanism comprises around left bearing 11 and the swivel pin 7 of right bearing 12 rotations, the retracing spring 8 resetting for swivel pin 7, for swivel pin 7 is carried out to spacing upper waist hole 9 and lower waist hole 10, described left front 31 and right front 32 is provided with baffle plate 13.
During work, draft arm 2 is mentioned, be positioned at left front 31, 6 upper ends, waist hole on right front 32, rotation traction traction arm 2, placement level, aligning tailstock pushes, swivel pin 7 is under the effect of draft arm 2, around left bearing 11, right bearing 12 rotations, swivel pin 7 lifts, the annulus 4 of draft arm 2 is crossed swivel pin 7 and is entered in tailstock, owing to thering is positioning action in tailstock, swivel pin 7 resets under the effect of retracing spring 8, make swivel pin 7 fall into the annulus 4 of draft arm 2, complete link, more link by that analogy, because the mode linking has very large degree of freedom, there is flexibility, in motion process, to uphill/downhill, turn all without impact in left and right,
Due to the effect of retracing spring 8, swivel pin 7 is inserted in the annulus 4 of draft arm 2 all the time, prevents that draft arm 2 from coming off; When separated, tramp with one's feet and step on the top of swivel pin 7, swivel pin 7 rotates, lifts, and promotes loading dolly, make draft arm 2 depart from swivel pin 7, draft arm 2 rotations are raised up to vertical ground position, put down, slip into 6 lower ends, waist hole on left front 31, right front 32, draft arm 2 is fixed, complete separation, simple to operate, improved efficiency; Because draft arm 2 is packed up, saved storage space, prevented again the contingency that draft arm 2 does not fixedly cause.
