The structural improvement of the main body of the folding scooter enables the unfolding or folding operation of the main body of the folding scooter to be more convenient and enables the structure of the main body of the folding scooter to be more steady and more reliable to guarantee the safe use of the scooter. The main body of the folding scooter of the utility model has the advantages of scientific design, reasonable and simple structure, convenient and rapid folding or unfolding operation, beautiful appearance, safe use, etc.

Description

Folding scooter main body

The utility model relates to physical culture or amusement appliance scooter, especially a kind of architecture advances to folding scooter main body.

Scooter is as a kind of utensil for people's physical training or recreation, and is very popular, especially favored by the teenager.Traditional scooter is made up of for the stock handgrip of user's operational guidance the pedal that is provided with wheel and.Scooter is simple in structure, and small volume and less weight is used so be fit to very much people's outdoor activities.Yet in actual use, it is found that, and occupation of land side because the pedal of scooter and the geostationary L shaped body that the stock handgrip is constituted are very inconvenient when carrying.For this reason, the scooter of folding structure has become the product of people's first-selection.Folding scooter is that the stock handgrip is installed on the pedal in hinged mode, and the stock handgrip can be relative folding with pedal.For satisfying the fixing of the folding or deployed condition of stock handgrip and pedal, one location mechanism is set in the junction of stock handgrip and pedal usually, this mechanism utilizes spanner to pull fork, and fork drives fulcrum, makes its pull-up leave locating slot and enters sliding rail, use the hand lower intermediate tube then, middle pipe just is that circular motion is made in the center of circle with the mandrel, and when arriving horizontal level, fulcrum is subjected to the pulling force effect of extension spring to enter locating slot, the locking quick detach can make the scooter after folding fix.Above-mentioned detent mechanism complex structure is made difficulty, and uses troublesome poeration.

The purpose of this utility model is the deficiency that exists at above-mentioned folding scooter, provides that a kind of location is reliable more, the more folding scooter main body of operation.

Folding scooter main body of the present utility model, comprise: the pedal that is provided with support, the front fork that is used for installing the stock handgrip is managed, pipe is installed on the support of pedal in the front fork by rotating shaft, have the deep-slotted chip breaker that can match on the support with the set bearing pin in pipe bottom in the front fork, the two ends of deep-slotted chip breaker are equipped with detent, one end of bearing pin is equipped with and prevents its axially snap ring of dislocation, it is characterized in that: the arm of pipe is a square structure pipe in the front fork, square structure pipe inner bottom surface is provided with tooth bar, bearing pin is the central shaft of a gear, this gear is arranged in the square structure pipe, can mesh with square structure pipe inner bottom surface tooth bar, bearing pin is provided with and can impels it to embed the extension spring of deep-slotted chip breaker end detent; Bearing pin one end is provided with the handgrip that can impel its rotation.

The design principle that this reality is made novel folding scooter main body is: be packed in gear on the bearing pin by the handgrip turn, gear is cooperated with the set tooth bar in the end in the square structure pipe move up, be directed at the detent that the bearing pin that is erected on the support deep-slotted chip breaker can break away from the deep-slotted chip breaker end with the rotation of gear.At this moment, folding scooter main body just is in the activity adjustment state, puts in place in case regulate, and utilizes extension spring then can make bearing pin embed deep-slotted chip breaker end detent, latch-up structure.The architecture advances of this folding scooter main body can make the expansion or the folding operation of folding scooter main body convenient, and structure is more solid and reliable, thereby guarantees the safe handling of scooter.This folding scooter body design science, rational in infrastructure, simple, have folding or launch easy to operate, quick, good looking appearance, advantage such as safe and reliable.

The concrete structure of folding scooter main body of the present utility model is provided in detail by the following drawings and embodiment.

Fig. 1 is the contour structures schematic diagram of folding scooter main body;

Fig. 2 is a folding scooter main body D-D position profile structural representation shown in Figure 1;

Fig. 3 is a folding scooter main body C-C position profile structural representation shown in Figure 1;

Fig. 4 is folding scooter main body A shown in Figure 2-A position profile structural representation.

Embodiment: can be clear that from Fig. 1,2, folding scooter main body has a pedal 2 that is provided with support 1, the front fork that is used for installing the stock handgrip manages 3, and pipe 3 is made of middle pipe 9 and arm 10 in the front fork, and the arm 10 of pipe 3 is hinged by rotating shaft 4 and the support 1 that is installed on the pedal 2 in the front fork.Have the deep-slotted chip breaker 6 that can match with the set bearing pin 5 in pipe 3 arms, 10 bottoms in the front fork on the support 1, the two ends of deep-slotted chip breaker 6 are equipped with detent 7, and an end of bearing pin 5 is equipped with and prevents its axially snap ring 8 of dislocation.The arm 10 of pipe 3 is a square structure pipe (see figure 3) in the front fork, arm 10 inner bottom surfaces are provided with tooth bar 11, bearing pin 5 is the central shaft (see figure 4) of a gear 12, this gear 12 is arranged in the arm 10, can mesh with arm 10 inner bottom surface tooth bars 11, bearing pin 5 sets and can impel it to embed the extension spring 13 of deep-slotted chip breaker 6 end detents 7, one end of extension spring 13 is nested with on bearing pin 5, the other end of extension spring 13 is nested with in rotating shaft 4, under the effect of extension spring 13, the deep-slotted chip breaker 6 on bearing pin 5 and the support 1 keeps cooperating and contacts.Bearing pin 5 one ends are provided with the handgrip 14 that can impel its rotation.
