The utility model relates to the jiffy stand technical filed, in particular to a double-column jiffy stand, comprising an upper connecting part and two support columns, wherein, the two support columns are connected with each other into the shape of an inversed V; a connecting part of the two support columns is hinged with the upper connecting part; the top of the connecting part takes the shape of an arc; a fixed shaft is arranged on the connecting part; a middle connecting part is provided with a clamping surface matching with the arc of the top of the connecting part; a through hole is arranged on the middle connecting part and penetrates through the clamping surface of the middle connecting part; a screw passes through the through hole and is in threaded connection with the fixed shaft; a groove for the screw to rotate around the fixed shaft is arranged on the connecting part. The utility model has the advantages that: when the angle of the two support columns and the horizontal plane is needed to adjust, the screw is slackened and the two support columns are made to be rotatable; when the support columns are adjusted to an adequate angle, the screw is tightened, and the clamping surface and the top of the connecting part are made to contact each other closely; at this point, the relative position of the two support columns and the upper connecting part is fixed, thereby the jiffy stand is quite convenient in use.
Description
Technical field:
The utility model relates to the jiffy stand technical field, particularly the twin columns jiffy stand.
Background technology:
Bicycle is to be subjected to one of popular vehicle deeply, and it has advantages such as energy-saving and environmental protection, and it can also help people's body-building, and the bicycle project also is a kind of of sports.Nowadays, the kind of bicycle also has a lot, for example load bicycle, mountain bike or the like, no matter and be which kind of bicycle, it all needs to stop places, this just needs support whole bicycle by jiffy stand.Existing bicycle parking rack, it generally is the straight-bar form, and promptly an end is rotatable is fixed on the bicycle, and the other end is used for contacting with ground, has spring to hook jiffy stand on the bicycle in addition, reaches fixing with the rotation that realizes jiffy stand.This jiffy stand has only one to be used for the strong point that contacts with ground, and this strong point and front-wheel touchdown point, trailing wheel touchdown point together support bicycle so just make the bicycle integral inclination, therefore is unfavorable for parking of bicycle.The applicant develops the twin columns jiffy stand; its upper end is fixedly connected on the bottom of bicycle middle-end; its lower end has two pillar stiffeners; during bicycle parking; by the front-wheel touchdown point; two pillar stiffeners of twin columns jiffy stand support bicycle; so just can make the whole held stationary of bicycle and do not tilt; in addition; the applicant with regard to the adjustable length structure application of two pillar stiffeners patent protection; the angle of this twin columns jiffy stand can not free adjustment; therefore, the applicant improves this twin columns jiffy stand in this application, to improve the result of use of twin columns jiffy stand.
The utility model content:
The purpose of this utility model is to provide the twin columns jiffy stand at the deficiencies in the prior art, and the angle of its pillar stiffener can free adjustment.
For achieving the above object, the utility model adopts following technical scheme:
It is made of upper end connecting portion, two pillar stiffeners, and two pillar stiffeners link together and are " people " font, and the connecting portion of two pillar stiffeners and upper end connecting portion are hinged.
The lower end of described upper end connecting portion has middle interconnecting piece, and the connecting portion of middle interconnecting piece and two pillar stiffeners is hinged.
Described connecting portion top is curved, is furnished with anchor shaft on the connecting portion, middle interconnecting piece has the clamping face that matches with connecting portion top arc, offer through hole on the middle interconnecting piece, this through hole penetrates the clamping face of middle interconnecting piece, screw is threaded with anchor shaft after passing this through hole, offers the groove that can supply screw to rotate around anchor shaft on the connecting portion.
Described middle interconnecting piece and upper end connecting portion are hinged.
Described connecting portion top forms groove, also forms groove on the clamping face.
Be carved with datum line on the described middle interconnecting piece, be carved with the mark line that is used for the datum line contraposition on the connecting portion.
The beneficial effects of the utility model are, when needing to regulate the angle of two pillar stiffeners and horizontal surface, unscrew screw, make two pillar stiffeners rotatable, when being adjusted to suitable angle, clamping face and connecting portion top closed contact are got final product screw means, this moment, the relative position of two pillar stiffeners and upper end connecting portion was fixed, and is very easy to use.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the one anglec of rotation view of pillar stiffener of the present utility model;
Fig. 2 is its two anglecs of rotation view of pillar stiffener of the present utility model;
Fig. 3 is its three anglecs of rotation view of pillar stiffener of the present utility model;
Fig. 4 is another angle scheme drawing of the present utility model;
Fig. 5 is a partial enlarged drawing of the present utility model.
The specific embodiment:
See accompanying drawing 1-5, the utility model is made of upper end connecting portion 10, two pillar stiffeners 20, and upper end connecting portion 10 is captiveed joint with bicycle; Two pillar stiffeners 20 link together and are " people " font, the connecting portion 22 of two pillar stiffeners 20 is hinged with upper end connecting portion 10, since having adopted above-mentioned articulated manner, can regulate two pillar stiffeners 20 and the angle of horizontal surface, so that it reaches required requirement.
The lower end of described upper end connecting portion 10 has middle interconnecting piece 30, and the connecting portion 22 of middle interconnecting piece 30 and two pillar stiffeners 20 is hinged; Middle interconnecting piece 30 of the present utility model is hinged with upper end connecting portion 10; Middle interconnecting piece 30 also can be direct and upper end connecting portion 10 is made of one piece.
Described connecting portion 22 tops are curved, is furnished with anchor shaft 222 on the connecting portion 22, middle interconnecting piece 30 has the clamping face 32 that matches with connecting portion 22 top arcs, offer through hole on the middle interconnecting piece 30, this through hole penetrates the clamping face 32 of middle interconnecting piece 30, screw 40 is threaded with anchor shaft 222 after passing this through hole, and offering on the connecting portion 22 can be for the groove 224 of screw 40 around anchor shaft 222 rotations; After adopting this structure, screw 40 can drive anchor shaft 222 rotations, and perhaps screw 40 is motionless with anchor shaft 222, and connecting portion 22 rotates around anchor shaft 222 with two pillar stiffeners 20, thereby reaches the purpose of the angle of regulating two pillar stiffeners 20 and horizontal surface; When needing to regulate, unscrew screw 40, make two pillar stiffeners 20 rotatable, when being adjusted to suitable angle, screw 40 being screwed the clamping face of making 32 get final product with connecting portion 22 top closed contacts, this moments two, pillar stiffener 20 was fixed with the relative position of upper end connecting portion 10.
