Abstract

The utility model discloses a tricycle; two hollow sleeve tubes are fixedly arranged at both sides of the rear end of a central frame; a clamping hole penetrating through a pipe wall is arranged on the sleeve pipe; two insertion tubes corresponding to the two sleeve tubes of the central frame are arranged at the front end of the frame body of a rear wheel frame; the insertion tubes are inserted with the two sleeve tubes; an elastic fastener is respectively arranged in the two insertion tubes; a convex button penetrating through the preset clamping hole of the pipe wall is arranged on the elastic fastener; when the utility model is assembled, the two insertion tubes at the front end of a rear wheel frame are aligned and directly inserted in the two sleeve tubes of the central frame; the convex button of the elastic fastener is pressed and butted in advance to be draw-in to slide together in the sleeve tube; when the insertion tubes corresponding to the sleeve tubes are inserted into a certain position, the convex button on the elastic fastener automatically bounces to clamp in the clamping hole of the sleeve tube; thus, the utility model is quickly assembled to position. When the utility model is folded, the convex button is pressed to be draw-in the sleeve tubes are drew out and the rear wheel frame is detached; thus, the utility model can be freely placed and stored. Compared with the common tricycle, the utility model has the advantages of simple structure, correspondingly lower cost, and convenient and safe operation.

Description

Three-wheel vehicle

Technical field

The utility model relates to a kind of bicycle, refers to a kind of three-wheel vehicle of children's ride-on especially.

Background technology

Specialize in the carriage for children that the child drives at present and be set as the three-wheel vehicle form mostly, sail Shi Buhui and topple over so that ride, and its basic car body design mainly is to connect front forked frame at central vehicle frame the place ahead of car body mat front bar pivot, front forked frame is worn the top of pivot front bar and is connected handgrip, the below is pivot dress front-wheel then, and directly being provided with the crank shaft pedal in the wheel axle center of front-wheel, the joint chair pad is established on central vehicle frame top, and constitutes complete child's tricycle; When driving this type of child's tricycle, children can be seated on the seat cushion and trample the crank shaft pedal and order about the front-wheel lift-over with both feet, and then divide a word with a hyphen at the end of a line before and after driving car body, and hold the handgrip that joins above the front forked frame and control the car direct of travel.

The above-mentioned known three-wheel vehicle structure of detailed sight, its car body framework belongs to a fixing kenel, and the fixed type car body adds three wheeled frameworks, promptly quite take up space, thus comparatively inconvenience of collection, therefore, promptly there is the dealer to develop collapsible child's tricycle, mostly the folding three-wheel vehicle of commonly using is in be provided with the bending joint than the long bone frame, to fold skeleton reduction width over sides of car body, length; This folding type fold form, when its inflection point, many places of operation, can require great effort time-consuming and trouble, and crush the people easily, aspect manufacturing cost, it increases bending joint designs and its locating structure, even spare part increases, when not only assembling is taken a lot of work, human cost increases relatively, and simultaneously, its productive costs is in a single day higher, this than low-price market, just can weaken the competitive power on its price for the carriage for children series products.

The utility model content

The purpose of this utility model is to provide a kind of easy three-wheel vehicle that folds.

For achieving the above object, solution of the present utility model is: a kind of three-wheel vehicle, its both sides, central vehicle frame rear end set firmly two sleeve pipes that are hollow, this sleeve pipe is provided with the hole clipping that connects tube wall, rear wheel frame is established at corresponding central vehicle frame two sleeve pipes of its support body front end and is connected to two intubate, this two intubate is plugged in two sleeve pipes, respectively establishes in two intubate into a snap-on spare, has the protruding button of the default hole clipping of tube wall that stretches through out on its snap-on spare.

After adopting said structure, during combination, rear wheel frame can directly insert involutory two sleeve pipes in central vehicle frame of front end two intubate, compresses in advance to contract in the protruding button of snap-on spare and together slide in the sleeve pipe, after the relative sleeve pipe sleeve of intubate puts in place, protruding button on its snap-on spare can be upspring automatically and be snapped in the hole clipping of sleeve pipe, thereby winding is fixed fast, when folding, by contracting in the belling button, detach intubate and rear wheel frame is separated, and then it freely can be put collection; The utility model is compared with the product of commonly using, and fold easy and do not have the worry that crushes the people, and spare part is less, and cost is low, and for carriage for children series products market, its price has certain competitive power.

The specific embodiment

At first consult shown in Figure 1, the utility model three-wheel vehicle, its central vehicle frame 1 front end connects front forked frame 2 with front bar 11 pivots, and the front-wheel 3 that is pivoted in the bottom of front forked frame 2, and establish in central vehicle frame 1 rear portion and to connect rear wheel frame 4, rear wheel frame 4 two ends are provided with two trailing wheels 5, and the wheel of front-wheel 3 is coupling and establishes crank shaft 6 and pedal 7, and the upper end that makes front forked frame 2 wear pivot front bar 11 is received vertical tube 21 and is provided with Level handle 22; And the improvement part of this case is that the rear wheel frame 4 of car body is set as the form of separating movable winding with central vehicle frame 1, and makes its connecting structure have the effectiveness of tearing group fast open, and its principal feature structure design is:

The both sides, rear end of this central authorities' vehicle frame 1 set firmly two and are the sleeve pipe 12 of hollow backwards, and are provided with the hole clipping 121 of perforation tube wall in this sleeve pipe 12;

This rear wheel frame 4 is established in corresponding above-mentioned central vehicle frame 1 two sleeve pipes 12 of its support body front end and is connected to two intubate 41, the external diameter of this two intubate 41 is with respect to the internal diameter of above-mentioned sleeve pipe 12 and plug, and in two intubate 41, respectively establish, and make snap-on spare 42 be provided with to stretch through out the protruding button 421 of the default hole clipping of tube wall into a snap-on spare 42.

When the rear wheel frame 4 of three-wheel vehicle combines with central vehicle frame 1, as Fig. 2,3, shown in 4, can be with the two intubate 41 involutory sleeve pipes 12 that are plugged in central vehicle frame 1 rear end both sides of rear wheel frame 4 with its support body front end, and compress in advance and contract in the protruding button 421 of snap-on spare 42 and together slide in the sleeve pipe 12, after intubate 41 relative sleeve pipe 12 sleeves put in place, then protruding button 421 can mat snap-on spare 42 the elastic spring ejection upspring, and the hole clipping 121 that snaps in sleeve pipe 12 is automatically fixed the location, so, can be apace firm winding central authorities vehicle frame 1 and rear wheel frame 4 these two large divisions' the car body that separates, and then be combined into a complete three-wheel vehicle.

In addition, if the rear wheel frame 4 that need disassemble car body is during in order to collection, then only need hole clipping 121 by the disengaging sleeve pipe 12 that contracts in the belling button 421, intubate 41 can be extracted out sleeve pipe 12 and separated rear wheel frame 4, by this, its car body is disassembled and is separated into horizontal rear wheel frame 4 and vertical central vehicle frame 1 two large divisions who comprises front-wheel, seat cushion mechanism, and be beneficial to the individuality of its separation is freely put collection with arbitrarily angled, direction.
