Detailed description of the invention
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model embodiment folding trailer deployed condition schematic diagram 1, folding trailer as can be seen from Figure in the present embodiment has four wheels, front-wheel support 1, rear wheel support 2 and base 3, wherein four wheels are arranged on the bottom of front-wheel support 1, rear wheel support 2 respectively, can rotate around the jointed shaft of correspondence.The top of front-wheel support 1 and rear wheel support 2 is articulated and connected, and therefore the two can rotate mutually around top.Base 3 is divided into the underside area of the first base 31 and the second base 32, first base 31 and front-wheel support 1 hinged, and the underside area of the second base 32 and rear wheel support 2 is hinged, the first base 31 and the second base 32 also hinged; Therefore can mutually rotate between the first base 31 and the second base 32, the first base 31, second base 32 can rotate relative to front-wheel support 1, rear wheel support 2 respectively.In addition, in the upside of the first base 31 and the second jointed shaft, the position that is positioned at the second base 32 also has spacing catch, when folding trailer is opened, spacing catch blocks the first base 31, second base 32 to be continued to be rotated down, and makes the first base 31 and the second base 32 substantially be in same plane.Now, base 3, front-wheel support 1 and rear wheel support 2 three define leg-of-mutton fixed sturcture, make each rod member position of folding trailer relatively fixing, ensure that stability when folding trailer is opened; And moment is applied downwards in base 3 both sides, the both sides being namely positioned at the first base 31 and the second base 32 jointed shaft apply moment, and the first base 31 and the second base 32 rotate around the jointed shaft be connected, and achieve the folding of base 3.In the present embodiment, conveniently apply external force, be provided with foot-driven lever 33 in the end of the second base 32, when needing folding, jam on the folding that foot-driven lever 33 just can realize folding trailer.Certainly, corresponding foot-driven lever 33 also can be set in the first base 31 side; Should be appreciated that the function of foot-driven lever 33 in practical application also realizes by the position of the first base 31, second base 32 side away from jointed shaft place, also foot-driven lever 33 can not be set.
The folding trailer of the utility model embodiment also comprises the first strut bar 4, second strut bar 5, front rail bar 6, back wall railing 7, head rod 8, second pipe link 9, first turning rod 10 and the second turning rod 11.Wherein front rail bar 6 and front-wheel support 1 hinged, front rail bar 6 and the first strut bar 4 hinged, first strut bar 4 is hinged with head rod 8, first turning rod 10 respectively again, and head rod 8 is hinged with rear wheel support 2, and the first turning rod 10 is hinged with front-wheel support 1; Back wall railing 7 and rear wheel support 2 hinged, back wall railing 7 and the second strut bar 5 hinged, the second strut bar 5 is hinged with the second pipe link 9, second turning rod 11 respectively again, and the second pipe link 9 is hinged with front-wheel support 1, and the second turning rod 11 is hinged with rear wheel support 2.When folding trailer is opened and is born gravity, whole trailer has the trend moved downward, therefore rear wheel support 2 tractive head rod 8 is pushed against on front support rod, front-wheel support 1 tractive second pipe link 9 is pushed against on back support rod, front rail bar 6, first strut bar 4 and front-wheel support 1 form triangle fixed sturcture, back wall railing 7, second strut bar 5 and rear wheel support 2 also form leg-of-mutton fixed sturcture, ensure that the stability of rail bar structure.When needs folding trailer, head rod 8 promotes the first strut bar 4 and departs from front-wheel support 1, and the second pipe link 9 promotes the second strut bar 5 and departs from rear wheel support 2; Meanwhile, due to the first turning rod 10 and the first strut bar 4 is hinged, the second turning rod 11 and the second strut bar 5 hinged, the first turning rod 10 tractive first strut bar 4 moves downward, and the second turning rod 11 tractive second strut bar 5 moves downward; First strut bar 4, second strut bar 5 the first rail bar that also tractive is corresponding respectively, the second rail bar rotate, and the state making whole folding trailer present Fig. 2 also finally reaches the state of Fig. 3.
In order to realize good fixing, second strut bar 5 well the fixing on rear wheel support 2 of the first strut bar 4 on front-wheel support 1 when folding trailer is opened, the position on front-wheel support 1, rear wheel support 2 corresponding clamping first strut bar 4, second strut bar 5 has the first shackle member, the second shackle member respectively.In the present embodiment, the first shackle member, the second shackle member are plastic clip fitting, head rod 8 and the first shackle member hinged, the second pipe link 9 and the second shackle member hinged.Be appreciated that in other embodiments, the first shackle member and the second shackle member also can be arranged on the end of the first strut bar 4 and the second strut bar 5 respectively.。Also can be found out by Fig. 2, the head rod 8 of the present embodiment king-rod is arranged on outside the left and right of trailer, and the second pipe link 9 is arranged on the inner side of trailer, prevents from interfering therebetween.
Folding trailer in the present embodiment also has mop rod 12, and the two ends of mop rod 12 are connected with the second strut bar 5 respectively.Mop rod 12 can slide along the bearing of trend of the second strut bar 5.Mop rod 12 also has connecting element, and when mop rod 12 is stretched to applicable length, connecting element is fixedly connected with mop rod 12 and the second strut bar 5.The height of mop rod 12 can be adjusted like this according to the height of actual user, and after folding mop rod 12 is contracted to minimum.
Front-wheel support 1 in the present embodiment, rear wheel support 2, front rail bar 6 and back wall railing 7 are articulated with the first jointed shaft, first strut bar 4, head rod 8 and the first turning rod 10 are articulated with the second jointed shaft, and the second strut bar 5, second pipe link 9 and the second turning rod 11 are articulated with the 3rd jointed shaft.Like this can the less punching at each rod member, conveniently install and improve the intensity of each rod member.
It should be noted that each rod member mentioned in above embodiment, tube-like piece or sheet shaped piece can be adopted in actual applications, do not affect the realization of each connection structure; Certainly, also the rod member of different materials, different qualities can be selected to realize connecting according to embody rule condition in other embodiments.
Folding trailer in above the utility model embodiment is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment; the explanation of above embodiment just understands core concept of the present utility model for helping; when not departing from the utility model principle; also can carry out some improvement and modification to the utility model, these improve and modify and also fall in protection domain of the present utility model.
