Abstract
A fast securing device for a light vehicle is characterized by comprising an inner sleeve, a nut, an outer sleeve and at least one jaw, wherein the inner sleeve is arranged on a bottom support, in interference fit with the bottom support and longitudinally provided with at least one oblique hole along the periphery; an upper opening of the oblique hole tilts towards the bottom support; the nut is arranged on the inner sleeve; the outer sleeve is arranged at the outer sides of the inner sleeve and the nut and is in interference fit with the nut; and the lower end of the jaw is inserted and arranged in the oblique hole of the inner sleeve, the upper end of the jaw extends out of the bottom support obliquely, and the outer surface of the jaw is formed with outer threads and connected with the nut by the threads and drives the jaw to move up and down through the rotation of the nut, so that the jaw can butt against or separate from a movable support. The fast securing device is simple and compact in structure and convenient to use, and has the advantages of being long in service life, convenient to adjust and reliable 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.
Summary of the invention
The utility model technical matters to be solved is to provide a kind of light roadster simple and compact for structure, easy to use, reliable lock to use quick securing device to the above-mentioned state of the art; This device utilizes the rotation of overcoat; The rotation of drive nut; And then make with nut thread bonded assembly claw can with respect to interior put down mobile, thereby tighten or loosen travel(l)ing rest.
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 securing device, it is characterized in that this light roadster comprises with quick-locking device:
Cover is placed on the bottom bracket, and is connected with the bottom bracket interference in one, and said interior cover vertically offers at least one inclined hole along circumference, and the upper shed of said inclined hole is tilted to bottom bracket;
One nut puts in being fixedly mounted on;
One overcoat, the cover and the outside of nut in being installed in, and be connected with the nut interference;
In the inclined hole of cover, its upper end was stretched out bottom bracket obliquely at least one claw, its lower end were inserted in; The outside face of claw forms outside thread; With nut through being threaded, and the rotation through nut to drive claw up and down, thereby with offset locking or unclamp of travel(l)ing rest.
As improvement, form the convex shoulder of equidistance on the outside face of said travel(l)ing rest, the upper end of said claw forms the kink that cooperates with said convex shoulder, and when claw was upwards movable, the kink of said claw snapped in the convex shoulder travel(l)ing rest is locked.
Improve, said nut is made up of the nut of two semicircles again.
At last, said inclined hole is 2～4 of well-distributeds, and preferred 3, said claw is 2～4 that equate with the inclined hole number, preferred 3.
Compared with prior art, the advantage of the utility model is: simple and compact for structure, easy to use; Utilize the rotation of overcoat, drive the nut rotation, so make with nut thread bonded assembly claw can with respect to interior put down mobile; Thereby the locking travel(l)ing rest because coupling mechanism force is under the state of non-threaded locking, to produce, does not need predetermincd tension; Therefore, should compare, have the advantage of long service life, easy to adjust, reliable lock with catch gear commonly used.

Fig. 1 is the structural principle scheme drawing of the utility model embodiment;
Fig. 2 is the structure birds-eye view of the utility model embodiment.
Wherein: 1, travel(l)ing rest, 2, claw, 3, nut, 4, overcoat, 5, interior cover, 6, bottom bracket.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure; A kind of light roadster is used quick-locking device; Cover 5, nut 3, overcoat 4 and claw 2 in comprising, said interior cover 5 is placed on the bottom bracket 6, and is connected with bottom bracket 6 interference; Cover 5 vertically evenly offers three inclined holes along circumference in said, and the upper shed of said inclined hole is tilted to bottom bracket 6; Said nut 3 is made up of the nut of two semicircles, and on the cover 5, said overcoat 4 is installed in the outside of interior cover 5 and nut 3 in being fixedly mounted on; And be connected with nut 3 interference, said claw 2 is three, in its lower end is inserted in the inclined hole of cover 5; Its upper end stretch out bottom bracket 6 obliquely, the outside face of claw 2 forms outside thread, with nut 3 through being threaded; Form the convex shoulder of equidistance on the outside face of said travel(l)ing rest 1, the upper end of said claw 2 forms the kink that cooperates with said convex shoulder, like this when rotary sleeve 4; And then rotation of nut 3; Thereby drive the up and down of claw 2, when claw 2 was upwards movable, the kink of said claw 2 snapped in the convex shoulder travel(l)ing rest is locked.
During use, when clickwise overcoat 4, overcoat 4 drives nut 4 rotations, makes claw 2 internally overlap 5 mutually and moves down, thereby unclamp travel(l)ing rest 1, in order to regulate the height of travel(l)ing rest 1; When left-hand revolution overcoat 4; Nut 3 rotates simultaneously, and make claw 2 internally overlap 5 mutually and move up, thus fastening travel(l)ing rest 1; Because the convex shoulder of uniform distances is arranged on the outside face of travel(l)ing rest 1; Therefore, claw 2 can not only fastening travel(l)ing rest 1, and can also effectively prevent the slippage of travel(l)ing rest 1 under the accident vibrations.Claw 2 moves up and down in the inclined hole of interior cover 4, can save the space, and compact form is finally realized the quick fastening function of securing device to travel(l)ing rest 1.
The invention that is used for explaining of the above-mentioned specific embodiment, rather than limit the invention, in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
