Abstract
The utility model relates to a novel folding tricycle scooter structure, comprising two bearing rods, a locating rod, a spring, a connecting rod and a screw. The connecting rod is fixedly connected with the left and right bearing rods; the locating rod is arranged in the bearing rods. The bearing rod is provided with a socket matching with the end head of the locating rod; the locating rod is pulled back to separate from the left socket of the bearing rod, then the left and right bearing rod can be folded upward. In addition, under the action of the spring, the locating rod contacts with the socket on the upper part of the bearing rod to achieve the locating after folding with a very ideal folding effect.
Description
Technical field
The utility model relates to a kind of three-wheel scooter, relates in particular to a kind of collapsible, portable three-wheel scooter.
Background technology
The three-wheel scooter foldable structure of prior art is shown in figure one, pole 1 is run through through hole 3 by bolt 6 and is rotationally connected with cramp bar 2, the cramp bar end is provided with deep-slotted chip breaker 8, and width and screw rod 4 are complementary, and deep-slotted chip breaker 8 two ends are established one and are slightly larger than screw rod 4 diameters and the through hole 7 that is complementary with screw rod 5, when firmly pressing screw rod 4, make screw rod 5 break away from lower end through hole 7, can implement to fold, when being folded to maximum angle, because spring 9 restoring force effects make screw rod 5 get back to upper end through hole 7 location.Though this kind mode can be implemented to fold, but there is following defective: when implementing to fold in the three-wheel scooter field, need hand by the screw rod 4 on the back stay, after making it to fold, by the screw rod 4 on another back stay, make another folding, so again, left and right sides pole 1 needs one one and folds, and inconvenience is implemented to fold simultaneously.In addition, this folding mode is clamped finger easily, has hidden danger.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of better folding mode of folding effect of implementing is provided.
In order to achieve the above object, the utility model has adopted following technical scheme:
A kind of three-wheel scooter foldable structure mainly is made up of cramp bar, radius stay, spring, connector and screw rod, it is characterized in that: cramp bar is captiveed joint with rotatable mechaninism, and a groove is respectively established in left end and upper end, and a through hole is established in the side; Connector one end is captiveed joint with left and right sides back stay, and the other end is set at
The shape structure is inserted for cramp bar;
The shape texture edge is provided with through hole, and is corresponding with the cramp bar through hole, passes for bolt, makes
Shape structure and cramp bar are rotatably connected; Radius stay left end and spring socket and side are provided with tapped bore, and the termination of right-hand member and cramp bar groove are complementary; Connector is provided with long slot, and long slot both sides penetrate screw rod and lock tapped bore on the radius stay.
Described spring one end is socketed on radius stay, and the other end is butted on the connector bottom, and spring can be provided with certain precompressed compression under normal condition.
Long slot one side on the described connector is
Shape, opposite side is
Shape can be done the rotation of certain angle around the radius stay axis direction when both sides screw rod spurs radius stay to the rear end.
The width and the screw diameter of described long slot are complementary.
Description of drawings
Figure one is the foldable structure figure of prior art;
Figure two is a three-wheel vehicle block diagram of the present utility model;
Figure three is a foldable structure exploded drawings of the present utility model;
Figure four is the folding figure of three-wheel vehicle of the present utility model.
Among the figure, 100A, 100B, cramp bar; 110A, 110B, 130A, 130B, groove; 120A, 120B, through hole; 200, pipe link; 210, radius stay; 220, spring; 230, tapped bore; 240,

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Extremely shown in Figure 4 as Fig. 2, a kind of three-wheel scooter foldable structure, mainly form by cramp bar (100A, 100B), radius stay 210, spring 220, connector 200 and screw rod (270,280), it is characterized in that: cramp bar (100A, 100B) is captiveed joint with rotatable mechaninism 400, a groove (130A, 130B) is respectively established in left end and upper end, and a through hole (120A, 120B) is established in the side; Connector 200 1 ends are captiveed joint with left and right sides back stay (300A, 300B), and the other end is set at
Shape structure 240 is inserted for cramp bar (100A, 100B);
Shape structure 240 sides are provided with through hole 250, and are corresponding with cramp bar (100A, 100B) through hole (120A, 120B), pass for bolt 290, make
Shape structure 240 is rotatably connected with cramp bar (100A, 100B); Radius stay 210 left ends and spring 220 sockets and side are provided with tapped bore 230, and the termination of right-hand member and cramp bar groove (130A, 130B) are complementary; Connector 200 is provided with long slot 260, and long slot 260 both sides penetrate screw rod 270 and lock tapped bore 230 on the radius stay 210.
Described spring 220 1 ends are socketed on radius stay 210, and the other end is butted on connector 200 bottoms, and spring 220 can be provided with certain precompressed compression under normal condition.
The width of described long slot 260 and screw rod 270 diameters are complementary.
The utility model compared with prior art owing to be set withThe long slot 260 of shape, When folding, spur screw rod 270 on the back stay 300A to the rear end, rotatably angle necessarily Degree, the screw rod 270 that spurs again after loosing one's grip on another back stay 300B is so far planted state, from And the folding left-right back stay (300A, 300B) that can make progress simultaneously, or prop up before directly folding downwards Bar 500. Certainly, also can fold another 300B of refolding behind the back stay 300A. In addition, this foldable structure only needs staff to pull back screw rod 270, remakes Small-angle Rotation, Can not clamp finger, handling safety. Obviously this kind folding mode effect is better.
