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 made up of three parts conventionally, screw rod, can be arranged on the nut of screw rod one end and be connected in the clamp handle of the screw rod other end with pin, this handle can rotate relative to screw rod, and bias is arranged on pin.In the time needing the travel(l)ing rest of locking support vehicle seat, first screw rod is inserted and is fixed in two coaxial apertures of set collar of 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, to lock travel(l)ing rest.It is unreliable that this structure of utilizing eccentric side face to compress and to produce coupling mechanism force can cause locking, because the predetermincd tension of nut is difficult to control, in the time that predetermincd tension is too large, the eccentric rotary of clamp handle may make set collar flick because 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 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 the claw being connected with nut thread can be moved 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 adopted technical scheme: 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 bottom bracket, and is connected with bottom bracket interference, and described inner sleeve longitudinally 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 arranged on the outside of inner sleeve and nut, and is connected with nut interference;
At least one claw, its lower end is 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, on the outside face of described travel(l)ing rest, form equidistant convex shoulder, the upper end of described claw forms the kink coordinating with described convex shoulder, and in the time that claw is upwards movable, the kink of described claw snaps in convex shoulder travel(l)ing rest is locked.
Improve, described nut is made up of two semi-circular portions again.
Finally, described inclined hole is 2～4 of well-distributeds, and preferably 3, described claw is 2～4 that equate with inclined hole number, preferably 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 the claw being connected with nut thread can be moved up and down with respect to inner sleeve, thus 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, be somebody's turn to do compared with conventional catch gear, there is long service life, easy to adjust, reliable lock.
Brief description of the drawings
Fig. 1 is the structural principle schematic diagram of the embodiment of the present invention;
Fig. 2 is the structure birds-eye view of the embodiment of the present invention.
Wherein: 1, travel(l)ing rest, 2, claw, 3, nut, 4, overcoat, 5, inner sleeve, 6, bottom bracket.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
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 bottom bracket 6, and be connected with bottom bracket 6 interference, described inner sleeve 5 longitudinally 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 made up of two semi-circular portions, be fixedly mounted in inner sleeve 5, described overcoat 4 is arranged on 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, on the outside face of described travel(l)ing rest 1, form equidistant convex shoulder, the upper end of described claw 2 forms the kink coordinating with described convex shoulder, like this in the time of rotary sleeve 4, and then rotation of nut 3, thereby drive the up and down of claw 2, in the time that claw 2 is upwards movable, the kink of described claw 2 snaps in convex shoulder travel(l)ing rest is locked.
When use, in the time of clickwise overcoat 4, overcoat 4 drives nut 4 to rotate, and the relative inner sleeve 5 of claw 2 is moved down, thereby unclamp travel(l)ing rest 1, in order to regulate the height of travel(l)ing rest 1; In the time of left-hand revolution overcoat 4, nut 3 rotates simultaneously, the relative inner sleeve 5 of claw 2 is moved up, thereby fastening travel(l)ing rest 1, on outside face due to travel(l)ing rest 1, there is the convex shoulder of uniform distances, 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 unexpected vibrations.Claw 2 moves up and down in the inclined hole of inner sleeve 4, can save 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 above-mentioned detailed description of the invention, instead of limit the invention, in the protection domain of spirit of the present invention and claim, any amendment and change that the present invention is made, all fall into protection scope of the present invention.
