Description
Technical field
The utility model relates to a kind of setscrew, and is especially relevant with a kind of multi-functional built-in can regulate setscrew.
Background technique
Setscrew is to rely on the rotation external nut, and the plush copper of dialling on the tight expansion sleeve inner screw is oppressed expansion sleeve, reaches fastening effect thereby expansion sleeve one end is expanded.At present, the setscrew of Xiao Shouing is of a great variety on the market, mainly contains expansion of metal screw and plastic expansion screw, the expansion pull bar of expansion of metal screw was changed once fixing just being difficult for, and the mating face out-of-flatness, and mounting plane can not be regulated, it is poor that the back whole structure is installed, and its using scope is restricted; The expansion dynamics of plastic expansion screw is not enough, poor stability, and application area is little.And, fit up the master worker at present and in fitment process, often run into setscrew fixedly during leading thread, leading thread is laid smooth inadequately because setscrew can not be regulated height, therefore generally all under it mode such as plug batten make the bottom surface smooth, inconvenient operation.
The model utility content
The purpose of this utility model is exactly to overcome the defective that above-mentioned mounting plane out-of-flatness, expansion pull bar can not be changed, and a kind of multi-functional built-in can regulate setscrew that can regulate mounting plane is provided, for this reason, the utility model by the following technical solutions:
Multi-functional built-in can regulate setscrew, comprise expansion tube and expanding nut, it is characterized in that: described setscrew also comprises adjusting nut, described expansion tube is divided into two sections, the diameter of bore of hypomere forms step by shoulder less than the diameter of bore of epimere, the hypomere of expansion tube has expansion slot, and the epimere inner hole wall is provided with screw thread; The lower end cylindrical of described expanding nut is conical, the upper end periphery is provided with the screw thread that coincide with the expansion tube internal thread, and hollow forms interior threaded hole, hypomere and its lower end that this expanding nut is arranged on expansion tube rely on described step by shoulder, during use, with bottle opener rotation expanding nut is thereby that expanding nut is shored step by takeing on the hypomere expansion that makes expansion tube, reaches fixation; Described adjusting nut is arranged on the expansion tube upper end, and its periphery is provided with the screw thread that coincide with the expansion tube internal thread, regulates the existing height to the fixed position of expansion tube thereby be screwed into the expansion tube of back-outing.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described setscrew also comprises center bolt, and this center bolt is threaded onto expansion tube and is screwed into the inner bolt hole of expanding nut.
Described center bolt is to hang the thing ring.
When the utility model uses, earlier expanding nut is screwed into expansion tube with bottle opener and makes expanding nut recline step by shoulder, after having assembled setscrew is placed on the swell fixture mounting point, with bottle opener rotation expanding nut the setscrew inflating end being expanded is fixed on the swell fixture mounting point, again adjusting nut also is screwed into the upper end of expansion tube with bottle opener, regulate showing to adjust the distance and to realize the Height Adjustment of setscrew of adjusting nut and expansion tube, center bolt can be threaded onto fixation after Height Adjustment is finished and be screwed into the interior threaded hole of expanding nut.
Use the utility model can reach following beneficial effect: 1, to realize the Height Adjustable of setscrew, thereby reached the effect of regulating the construction precision; 2, center bolt can arbitrarily be changed, and expansion tube can be general, has realized the multifunctional usage of setscrew; 3, guaranteed setscrew install and fix the back its collar extension smooth, make overall appearance more attractive in appearance.
Description of drawings
Fig. 1 is a sectional drawing of the present utility model.
Among the figure, 1, center bolt; 2, adjusting nut; 3, expansion tube; 4, expanding nut; 5 steps are by shoulder.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises expansion tube 3, expanding nut 4, adjusting nut 2 and centre bolt 1, expansion tube 3 is divided into two sections, the diameter of bore of hypomere forms step by shoulder 5 less than the diameter of bore of epimere, the hypomere of expansion tube 3 has expansion slot, the epimere inner hole wall is provided with screw thread, the lower end cylindrical of expanding nut 4 is conical, the upper end periphery is provided with and the identical screw thread of the internal thread of expansion tube 3, and hollow forms interior threaded hole, hypomere and lower end that expanding nut 4 is arranged on expansion tube rely on step by shoulder 5, adjusting nut 2 is arranged on the upper end of expansion tube 3, its periphery is provided with and the identical screw thread of the internal thread of expansion tube 3, and center bolt 1 is threaded onto expansion tube 3 and is screwed into the inner bolt hole of adjusting nut 2.
When the utility model uses, earlier expanding nut 4 usefulness bottle openers are screwed into expansion tube 3 and make expanding nut 4 recline step by shoulder 5, after having assembled setscrew is placed on the swell fixture mounting point, with bottle opener rotation expanding nut 4 inflating end of setscrew being expanded is fixed on the swell fixture mounting point, again adjusting nut 2 usefulness bottle openers are screwed into the upper end of expansion tube 3, regulate adjusting nut 2 and the distance of expansion tube 3 and can realize the Height Adjustment of setscrew, center bolt 1 can be threaded onto fixation after Height Adjustment is intact and be screwed into the interior threaded hole of expanding nut 4.
As another kind of mode of execution, center bolt is used for hanging article such as fan, electric light for hanging the thing ring when setscrew is fixed on the roof.
