Abstract

The utility model discloses an improvement structure of a foldable handlebar, which mainly comprises a handlebar frame, two handles, and a quick release piece, wherein, the handlebar frame refers to forming a transverse nozzle with a certain length on the top of a vertical tube and the transverse nozzle is used for the two handles to be arranged in a cottage grafting way, a clamp seat is formed between the upper and the lower positions of the middle part of the groove of the transverse nozzle and is used for the quick release piece to pass through and to be arranged by locking, whereas the two handles can be arranged on the left and the right sides of the transverse nozzle of the handlebar in the cottage grafting way by an elastic band, therefore, the quick release piece on the clamp seat of the transverse nozzle can ensure the two handles to achieves the practical efficiency of quick assembly and folding.

Description

The improvement structure of folding handles

Technical field

The utility model system is meant a kind of handle foldable structure design that applies to folding bicycle especially relevant for a kind of folding handles.

Background technology

Folding bicycle more and more can be subjected to customer's favor, owing to have the characteristic that does not take up space after folding, so collect easily or place trunk to carry and go out, especially handle is made the collapsible design of dwindling the space such as maybe can take out in recent years, as Fig. 7, two kinds of collapsible handles shown in Figure 8, mainly tie up to the leader and manage each socket one folding handgrip of both sides, this two handgrip and handle tube lock with a Fast detachable unit respectively; Yet the foldable structure of this two pattern is in assembling or must to operate two Fast detachable units when folding respectively urgent or unclamp, so not only slow in the use and manufacturing cost also can improve relatively.

Therefore, the inventor assembles again, folds under the situation that waits disappearance more slowly in view of aforesaid folding handles is expensive, and constantly improvement more progresses greatly product, is improved at shortcoming especially, develops the utility model structure eventually.

The utility model content

Main purpose of the present utility model is to provide a kind of assembling to fold the convenient fast and again improvement structure of economic folding handles.

To achieve these goals, the improvement structure of folding handles of the present utility model mainly comprises:

Leader's frame, it ties up to the horizontal adapter that riser top ends always is formed with a suitable length, and pegs graft for two handgrips, and horizontal adapter lateral wherein is provided with a profile groove, and the next place forms a holder on the profile groove stage casing of this horizontal adapter;

Two handgrips are by in the horizontal adapter that is plugged in handle rack about an elastic cord;

One Fast detachable unit is the horizontal adapter holder place that is located at handle rack, and is urgent or unclamp two handgrips in the horizontal adapter.

System just holds the grafting of two handgrips in this horizontal adapter.

Be provided with in this holder for a Fast detachable unit and place the perforation that lock is established.

The back side of this horizontal adapter respectively is provided with a knock hole in the place, both sides.

Be to be set as an outer recess than path on the inserted terminal outer tube wall of one handgrip, then be set as the mutual socket of big footpath inner recess of corresponding shape on the inserted terminal inner tubal wall of another handgrip.

The nearly inserted terminal place of this two handgrip respectively is provided with the elastomeric locating button of a tool.

Button is solid mutually for knock hole and locating button system.

By this, the practical effect that can make two handgrips can reach quick assembling and fold in the Fast detachable unit on the horizontal adapter holder.

The specific embodiment

At first, see also Fig. 1～Fig. 3, the improvement structure of the utility model folding handles mainly comprises:

Leader's frame 10, it ties up to the horizontal adapter 12 that a uprise 11 tops are formed with a suitable length, and peg graft for two

handgrips

20,30, horizontal adapter 12 laterals wherein are provided with a profile groove 120, and the next place forms a holder 121 on profile groove 120 stage casings of this horizontal adapter, be provided with perforation 122 in the holder 121, can place lock for a Fast detachable unit 40 and establish, the back side of this horizontal adapter 12 respectively is provided with a knock hole 123 in the place, both sides again;

Two

handgrips

20,30 is to be plugged in the horizontal adapter 12 of handle rack 10 by an elastic cord about 50, wherein be to be set as an outer recess 21 than path on the inserted terminal outer tube wall of a handgrip 20, then be set as the big footpath inner recess 31 of corresponding shape on the inserted terminal inner tubal wall of another handgrip 30, make two

handgrips

20,30 can be by this outer recess 21 socket mutually with inner recess 31, two handgrips 20 again, 30 nearly inserted terminal place respectively is provided with the elastomeric locating button 60 of a tool again, just supplies two

handgrips

20,30 can be located in knock hole 123 places of horizontal adapter 12 when being assembled in the horizontal adapter 12 of handle rack 10;

One Fast detachable unit 40 is horizontal adapter 12 holders 121 places that are located at handle rack 10, uses urgent or unclamps two

handgrips

20,30 in horizontal adapter 12.

More than for structure, the position of each member of the utility model and join the relation general introduction; Then, again the utility model assembling, folding action are stated as the back:

Continuous please the cooperation consulted Fig. 4, Fig. 5, wherein link two handgrips 20 that elastic cord 50 is arranged, 30 can be placed in horizontal adapter 12 both sides by horizontal adapter 12 profile grooves 120 places of handle rack 10 by its elastic cord 50, assemble Fast detachable unit 40 again, by this, two

handgrips

20,30 promptly is can be in horizontal adapter 12 places of handle rack 10 cover if fold, when desiring the fit use, with two

handgrips

20,30 are plugged in the horizontal adapter 12, system just can hold two handgrips 20 in this

horizontal adapter

12,30 peg graft, again for making two

handgrips

handgrips

20,30 buttons are limited in two knock holees, 123 places at horizontal adapter 12 back sides admittedly, and this two handgrip 20 simultaneously, 30 inserted terminal just utilizes outer recess 21 of formed corresponding shape and inner recess 31 designs, make two

handgrips

20,30 inserted terminal is sleeved in the horizontal adapter 12 mutually, at this moment, the Fast detachable unit 40 that can be placed by the holder 121 at horizontal adapter 12 profile grooves 120 places is with two

handgrips

20,30 again packing fix, use and finish assembling; Otherwise, unclamp Fast detachable unit 40 and can make two

handgrips

20,30 break away from the horizontal adapter 12 of handle racks 10 and folding folding (as shown in Figure 6).
