Abstract
A expansion screw consists of expansion tube(6), bolt(5), pad(4), locknut(3). The end of expansion tube(6) far from locknut(3) installs a expansion groove(10),the end of bolt far from locknuy screws a taper-shape nut(7) A inner hole opened in the end of the Expandable Tubular (6) matched nut (7)the shape of the trumpet (8), Block (9)on the top of the locknut (3) connected with the locking nut (3) as one body, a rotatable Block connected with a drop hanger (1).The expansion screw is simple structure and expansion of effective, easy to use. Using it is not be limited by field and can hang fans, chandeliers and other items on flattop also hang anythings without angle restriction on the wall even lock bicycle, battery truck and another anti-theft things.
Description
Technical field
The present invention relates to a kind of setscrew, specifically be a kind of widely used setscrews of using more.
Background technique
Setscrew is the engineering fastening piece that generally uses in the market, has commonly, and buckle ring shape is also arranged, and the latter comprises expansion tube, bolt, nut, interior cover.One one end band radial projection, and female in cover pack into from the end that an expansion tube has expansion slot, the internal thread of the bolt of buckle cover in the expansion tube the other end screws in, have packing ring, nut on the bolt, when screwing nut, the direction that interior cover is pulled to nut one end moves, the radial projection of interior cover one end is the end that the dilating expansion pipe has groove, thereby expansion tube is clamped in the impact opening.This complex structure, expansion effect is bad.
Because hook and bolt are one, that is to say that hook is stiff again, using scope is restricted.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of features simple structure and expansion effect good use setscrew more.
For solving the problems of the technologies described above, setscrew provided by the invention comprises expansion tube, bolt, pad, locking nut, and described expansion tube has expansion slot away from that end of locking nut.Described bolt is rotary with nut away from that end of locking nut, and the cylindrical of nut is up-small and down-big taper shape, and the endoporus that expansion tube has expansion slot one end is the horn mouth that matches of the profile with nut.
The top of described locking nut is provided with connecting base, and connecting base and locking nut are one, and connecting base is connected with one turnably and hangs the thing ring.
Described turnable connection is meant connecting base and hangs between the thing ring hinged with hinge pin.
The described thing ring that hangs can be hook-type, also can be annular.
After adopting above structure, owing to only be rotary with conical nut on the bolt away from that end of locking nut, so simple in structure and expansion effect is good, easy to use.Because the connecting base on the locking nut is to be connected turnably with hanging the thing ring, so not limited by the place again, can be at flat-top hang oneself electric fan, pendent lamp and other article; Can on body of wall, not be subjected to angle limits to hang any article; Also can ground lock bicycle, storage battery car and other antitheft article.For people's daily production and life provides convenience.
Description of drawings
Fig. 1 is the sectional view of setscrew of the present invention when making suspension hook.
Fig. 2 is the sectional view of setscrew of the present invention when making suspension ring.
Wherein, 1, hang the thing ring; 2, hinge pin; 3, locking nut; 4, pad; 5, bolt; 6, expansion tube; 7, nut; 8, horn mouth; 9, connecting base; 10, expansion slot.
Embodiment
Below in conjunction with the drawings and specific embodiments to further detailed explanation of the present invention.
Sectional view when making suspension hook by setscrew of the present invention shown in Figure 1 as can be known, setscrew of the present invention, comprise expansion tube 6, bolt 5, pad 4, locking nut 3, described expansion tube 6 has expansion slot 10 away from that end of locking nut 3, described bolt 5 is rotary with nut 7 away from that end of locking nut 3, the cylindrical of nut 7 is up-small and down-big taper shape, and the endoporus that expansion tube 6 has expansion slot 10 1 ends is the horn mouth 8 that matches of the profile with nut 7.The top of locking nut 3 is provided with connecting base 9, and connecting base 9 is an one with locking nut 3, and connecting base 9 usefulness hinge pins 2 are hinged with one and hang thing ring 1.Hang thing ring 1 and make hook-like.
When screwing locking nut 3, the direction that nut 7 is pulled to suspension hook 1 one ends moves, because nut 7 is conical, big one is the end that dilating expansion pipe 6 has expansion slot 10, thereby expansion tube 6 firmly is clamped in the impact opening.Because the connecting base 9 on suspension hook 1 and locking nut 3 tops is hinged with hinge pin 2, promptly suspension hook 1 can rotate for fulcrum by hinge pin 2, and 1 on suspension hook can be used for hanging various weights on flat-top or vertical body of wall, as ceiling fan, pendent lamp etc.
Sectional view when making suspension ring by setscrew of the present invention shown in Figure 2 hangs thing ring 1 and is not limited to hook-like as can be known, also can make ring-type, and is to adapt to different use occasions, stolen to prevent as pinning article such as storage battery car, bicycle on the ground.
