Abstract
The invention relates to a quick-fastening device for a lightweight car. The quick-fastening device is characterized by comprising an inner sleeve, a nut, a jacket and at least a jack catch, wherein the inner sleeve is sleeved on a bottom support and is in interference fitting connection with the bottom support; at least an inclined hole is longitudinally arranged on the inner sleeve along a circle; an upper opening of the inclined hole inclines toward the bottom support; the nut is fixedly installed on the inner sleeve; the jacket is installed at the outer side of the inner sleeve and the nut and is in interference fitting connection with the nut; the lower end of the jack catch is inserted in the inclined hole of the inner sleeve, and the upper end of the jack catch obliquely extends out of the bottom support; outer threads are formed on the outer surface of the jack catch; and the jack catch is in threaded connection with the nut and drives the jack catch to move up and down through the rotation of the nut so as to push against with a movable support to lock or loosen. The quick-fastening device for the lightweight car is simple and compact in structure, convenient to use and adjust, long in service life and reliable to lock.
Description
Technical field
The present invention relates to a kind of latching device, specifically a kind of Quick locking device for light vehicle.
Background technology
Existing light roadster latching device is comprised of three parts usually, namely 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 with pin, relatively screw rod rotation of this handle, and off-centre is installed on the pin.When needing the travel(l)ing rest of locking support vehicle 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 large, the eccentric rotary of clamp handle may so that set collar flick owing to application force is excessive, cause nut and screw flight connection to lose efficacy, part is impaired; And when predetermincd tension too hour, the eccentric rotary of clamp handle then can not compress travel(l)ing rest, therefore this structure can not be locked effective and rapidly, operation is more loaded down with trivial details simultaneously.
Summary of the invention
Technical matters to be solved by this invention is the fast securing device for light vehicle that a kind of simple and compact for structure, easy to use, reliable lock is provided for the above-mentioned state of the art, this device utilizes the rotation of overcoat, the rotation of drive nut, and then so that the claw that is connected with nut thread can move up and down with respect to inner sleeve, thereby tighten or loosen travel(l)ing rest.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of fast securing device for light vehicle is characterized in that this Quick locking device for light vehicle comprises:
One inner sleeve is placed on the bottom bracket, and is connected with the bottom bracket interference, and described inner sleeve vertically offers at least one inclined hole along circumference, and the upper shed of described inclined hole is tilted to bottom bracket;
One nut puts in being fixedly mounted on;
One overcoat is installed in the outside of inner sleeve and nut, and is connected with the nut interference;
At least one claw, its lower end are inserted in the inclined hole of inner sleeve, and its upper end is stretched out bottom bracket obliquely, the outside face of claw forms outside thread, be threaded connection with nut, and by nut to rotarily drive claw up and down, thereby with offset locking or unclamp of travel(l)ing rest.
As improvement, form equidistant convex shoulder on the outside face of described travel(l)ing rest, the upper end of described claw forms the kink that cooperates with described convex shoulder, and when claw was upwards movable, the kink of described claw snapped in the convex shoulder travel(l)ing rest is locked.
Improve, described nut is comprised of the nut of two semicircles again.
At last, described inclined hole is 2～4 of well-distributeds, and preferred 3, described claw is 2～4 that equate with the inclined hole number, preferred 3.
Compared with prior art, the invention has the advantages that: simple and compact for structure, easy to use, utilize the rotation of overcoat, the rotation of drive nut, and then so that the claw that is connected with nut thread can move up and down with respect to inner sleeve, thereby the locking travel(l)ing rest because coupling mechanism force is to produce under the state of non-threaded locking, do not need predetermincd tension, therefore, should compare with catch gear commonly used, have the advantage of long service life, easy to adjust, reliable lock.
Description of drawings
Fig. 1 is the structural principle scheme drawing of the embodiment of the invention;
Fig. 2 is the structure birds-eye view of the embodiment of the invention.
Wherein: 1, travel(l)ing rest, 2, claw, 3, nut, 4, overcoat, 5, inner sleeve, 6, bottom bracket.
The specific embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure, a kind of Quick locking device for light vehicle, comprise inner sleeve 5, nut 3, overcoat 4 and claw 2, described inner sleeve 5 is placed on the bottom bracket 6, and be connected with bottom bracket 6 interference, described inner sleeve 5 vertically evenly offers three inclined holes along circumference, and the upper shed of described inclined hole is tilted to bottom bracket 6; Described nut 3 is comprised of the nut of two semicircles, be fixedly mounted on the inner sleeve 5, described overcoat 4 is installed in the outside of inner sleeve 5 and nut 3, and be connected with nut 3 interference, described claw 2 is three, its lower end is inserted in the inclined hole of inner sleeve 5, its upper end is stretched out bottom bracket 6 obliquely, the outside face of claw 2 forms outside thread, be threaded connection with nut 3, form equidistant convex shoulder on the outside face of described travel(l)ing rest 1, the upper end of described claw 2 forms the kink that cooperates with described 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 described claw 2 snapped in the convex shoulder travel(l)ing rest is locked.
During use, when clickwise overcoat 4, overcoat 4 drives nuts 4 rotations, so that claw 2 relative inner sleeves 5 move down, thereby unclamps 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, so that claw 2 relative inner sleeves 5 move up, thereby 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 inner sleeve 4, can save the space, and compact form realizes that finally securing device is to the Quick fastening function of 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.
