Abstract

The utility model discloses a handle folded-plate structure. The handle frame is spaced provided with two handles, wherein, one handle is provided with a thimble, the outer end of the thimble pushed by a flexible member moves outward and located on the end of the other handle, thereby the two handles are elastic fixed in the extended mode. The thimble is fixedly provided with the end of the second handle by a quick-release device, thereby the two handles maintaining expansion steadily. To folding the two handles, the quick-release device should be released from the thimble and the second handle. After the thimble moved away from the second handle, the rolling and folding of the two handles can be very simply to operate.

Description

Handle folding structure

Technical field

The utility model relates to a kind of handle folding structure of hiding the handle rack when taking at bicycle or similar equipment.

Background technology

Bicycle that we are common or similar equipment, its second chief's tube space form can't change for fixing, so the user can't adapted space and elastomeric folding in addition, for general user in utilization, it truly has the puzzlement of portable inconvenience, and can't further improve portable fitness between itself and user, especially at carrying space limited automobile or Recreational Vehicle.

Because existing handle tube structure, all lack the structure that can convenient fold, therefore just there is the structure of No. the 427273rd, TaiWan, China patent announcement to produce, it is respectively to cooperate a handlebar in handle vertical tube two sides, two connecting straps, one quick detach, one bolt and a nut form, wherein handle vertical tube below two ends respectively are provided with an elasticity short slot, each weldering of two latter ends below is provided with one group and is corresponding set collar, handlebar is provided with one group in the weldering of below, appropriate position and is corresponding set collar, the length of this set collar is long than the set collar of handle vertical tube, the external diameter of handlebar is slightly less than the internal diameter of handle vertical tube in addition, the curved shape of vertical section of connecting strap, one side is provided with a fixed orifice, and opposite side is provided with one and adjusts slotted eye; By said structure, and the effect that tool is located be can when the folded bicycle handle, can obtain, and the convenience and the safety of carrying are beneficial to.

Only making a general survey of that this structure launches or fold still in conversion must could be for it by spanner or the like instrument, and quite inconvenience the more important thing is that the cost of its structure setting still has the space of improvement, and then reception degree in market is not high.

The utility model content

The purpose of this utility model provides a kind of quick folding of handle rack and upright handle folding structure of exhibition of making.

For achieving the above object, solution of the present utility model is: a kind of handle folding structure, it is first, second handle tube that is pivoted with in the handle rack interval, first in command's pipe is slidingly equipped with sleeve, this sleeve ora terminalis is by the effect of elastic element and fit is positioned second in command's pipe end edge, force first, second handle tube to be in the restriction state of expansion, this sleeve also is fixed in second in command's pipe with quick detach device bundle.

Described handle rack is made of support tube, cross-bridges and two vertical tubes; Support tube one end is fixedly arranged on standpipe, other holds then oblique extension forward and is welded in horizontally disposed cross-bridges stage casing, cross-bridges in two ends then respectively forward be installed with two vertical tubes, this vertical tube is worn the bolt that runs through the axle center of pulling in the rear end, make bolt be provided with a pivot seat in vertical tube front end lock, this pivot seat is relative is installed with first and second handle tube, the inner that first and second handle tube is adjacent be alternate and the position between two vertical tubes, and to make first and second handle tube can bolt be that rotate at the center.

Described first and second handle tube is a coaxial setting.

Described first in command's pipe is provided with negative thread in the endoporus of this end, this negative thread spiral shell is provided with cock body, make the cock body head be folded with spring perch in first in command's pipe end face, make the sheathed elastic element that is positioned with between cock body head and spring perch inner face, first in command pipe and elastic element periphery then sliding sleeve have the sleeve in a tool T shape hole, the place, large aperture of this sleeve is ccontaining for the elasticity element, and elastic element in addition end to be connected to sleeve big, small-bore handing-over sheet, and sleeve then welds in the outer end, large aperture and is provided with catch, this catch abuts against in the spring perch outside, elastic force pushing and pressing sleeve in order to do elastic element is preset makes the sleeve crane span structure be positioned first, between second chief's pipe.

Described sleeve in second in command's pipe end face vertically be provided with profile groove, the both sides of this profile groove are respectively equipped with the lock ear, this lock ear is provided with corresponding through hole, establishes for a quick detach device group.

After adopting such scheme, the utility model obtains firm expansion locating effect when first, second handle tube is connected; After discharging the quick detach device, the bundle of can get loose sleeve and second in command's pipe concerns admittedly, and and sleeve is moved apart under second in command's pipe at the default elastic force that overcomes elastic element, can operate first, second handle tube rotation folding like a cork.
