Abstract
The utility model discloses a quick locking device for a light vehicle, which is characterized in that the quick locking device comprises a fixing ring and a locking ring, wherein the fixing ring is sleeved on a bottom support and is in interference connection with the bottom support; a plurality of round grooves are arranged on the inner surface of the locking ring, one end of the locking ring is fixedly connected with the left end of the fixing ring in a rotatable way, and the other end of the locking ring is hinged with a locking handle through a pin shaft; meanwhile, the locking handle is arranged at the right end of the fixing ring through the matching of a locking screw and the round grooves, and a movable support is locked. The quick locking device has a simple structure and can be convenient to use, quick locking can be carried out by the matching of the round grooves on the inner surface of the locking ring and the locking screw, as the locking force is generated in the state of non-thread locking, pre-tightening force is not needed, therefore, compared with a common locking mechanism, the quick locking device has the advantages of long service life, convenience in adjustment and reliability in locking.
Description
Technical field
The utility model relates to a kind of latching device, specifically is that a kind of light roadster is used quick-locking device.
Background technology
Existing light roadster is used latching device, form by three parts usually, promptly screw rod, can be installed in the nut of screw rod one end and be connected in the clamp handle of the screw rod other end, this handle screw rod rotation relatively, and off-centre is installed on the pin with pin.When needs are locked the travel(l)ing rest of supporting seat; At first screw rod is inserted in two coaxial apertures of the set collar that is fixed on bottom bracket, at one end screw on nut and carry out pretension, then at other end rotational lock handle; Utilize the eccentric curved surface of clamp handle to be fixed ring, with the locking travel(l)ing rest.It is unreliable that this structure of utilizing the eccentric side face to compress and producing coupling mechanism force can cause locking; Because the predetermincd tension of nut is difficult to control; When predetermincd tension is too big; The off-centre rotation of clamp handle possibly make set collar flick owing to application force is excessive, causes nut and screw flight to connect disabler, and part is impaired; And when predetermincd tension too hour, the rotation of the off-centre of clamp handle then can not compress travel(l)ing rest, therefore this structure can not be locked to effective and rapid, and operates more loaded down with trivial details simultaneously.
The utility model content
The utility model technical matters to be solved is to provide a kind of light roadster simple in structure, easy to use, reliable lock to use quick-locking device to the above-mentioned state of the art; This device utilizes the rotation of binding ring with respect to fix screw; Make lock screw get in the circular groove of binding ring; Produce coupling mechanism force, the moving up and down of restraint support.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of light roadster is used quick-locking device, it is characterized in that this light roadster comprises with quick-locking device:
One set collar is placed on the bottom bracket, and is connected with the bottom bracket interference;
One binding ring; Offer a plurality of circular grooves on its inside face; One end of said binding ring is captiveed joint with the left end of set collar rotationally; The other end is connected with a clamp handle through bearing pin, is installed in the right-hand member of set collar simultaneously through lock screw and cooperating of circular groove, and the locking travel(l)ing rest.
As improvement, offer the annular groove that can supply clamp handle to embed on the outside face of said binding ring.
Improve again; Outwards offer mounting hole on the left and right sides end face of said set collar; One end of said binding ring has and the cooresponding through hole of set collar left end mounting hole; Through fix screw one end of binding ring is connected fixingly with the left end of set collar, said lock screw is arranged on the right-hand member mounting hole of set collar, locks with the circular groove of binding ring inside face.
At last, said circular groove is a plurality of of uneven distribution, and the outside diameter of said lock screw is greater than the diameter of circular groove.
Compared with prior art, the advantage of the utility model is: simple in structure, easy to use; Cooperate fast with lock screw through the circular groove on the binding ring inside face and to lock; Because coupling mechanism force is under the state of non-threaded locking, to produce, and does not need predetermincd tension, therefore; Should compare with catch gear commonly used, have the advantage of long service life, easy to adjust, reliable lock.

Fig. 3 is the cutaway view of Fig. 1 along the A-A line.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-3, a kind of light roadster is used quick-locking device, comprises set collar 1, binding ring 2 and clamp handle 3, and said set collar 1 is placed on the bottom bracket 7, and is connected with bottom bracket 7 interference; Offer the circular groove 21 of a plurality of positions uneven distribution on the inside face of said binding ring 2; One end of said binding ring 2 is captiveed joint with the left end of set collar 1 rotationally; The other end is hinged through bearing pin 4 and clamp handle 3; Be installed in the right-hand member of set collar 1 simultaneously through lock screw 6 and cooperating of circular groove 21, and locking travel(l)ing rest 8; Outwards offer mounting hole on the left and right sides end face of said set collar 1; One end of said binding ring 2 has and the cooresponding through hole of set collar 1 left end mounting hole; An end of binding ring 2 is connected fixing with the left end of set collar 1 through fix screw 5; Said lock screw 6 is arranged on the right-hand member mounting hole of set collar 1, and the outside diameter of lock screw 6 is suitably greater than the diameter of circular groove 21, makes that lock screw 6 can not only fixing and locking ring 2; And can also prevent the slippage of binding ring 2; Binding ring 2 can rotate with respect to fix screw 5 like this, thereby lock screw 6 is embedded in the circular grooves 21, locks travel(l)ing rest 8 through circular groove 21 and lock screw 6; On the outside face of said binding ring 2, offer the annular groove that can supply clamp handle 3 to embed, but insert in the annular groove of binding ring 2 behind clamp handle 3 left-hand revolutions, thereby save the space.
During use, when clickwise clamp handle 3, can select the circular groove 21 of binding ring 2 inside face diverse locations as required, thereby produce different coupling mechanism forces.Get into the circular groove of binding rings 2 when lock screw 6 after, because the outside diameter of lock screw 6 one ends is greater than the diameter of the circular groove 21 of binding ring 2, therefore, lock screw 6 can not only fixing and locking ring 2, and can also prevent the slippage of binding ring 2.In addition, owing on the outside face of binding ring 2 annular groove is arranged, therefore, but insert in the annular groove of binding ring 2 behind clamp handle 3 left-hand revolutions, thereby save the space, compact form is finally realized the quick locking function of latching device to travel(l)ing rest 8.
The above-mentioned specific embodiment is used for the utility model of explaining; Rather than the utility model limited; In the protection domain of the spirit of the utility model and claim,, all fall into the protection domain of the utility model to any modification and the change that the utility model is made.
