Abstract
The utility model provides a threaded nail, nut, the nail body and nail point including integrated into one piece, the nut with the nail point is located respectively the both ends of the nail body, the nail body divide into two sections, is upper segment and hypomere respectively, the upper segment is the anodontia district, the hypomere is the screw thread district, and the diameter that nail body screw thread was distinguished reduces to following closely sharp upper end by following closely body anodontia district lower extreme gradually, the screw thread in screw thread district is multiple thread, multiple thread's number of threads is the 4 -8 head, multiple thread's the transversal V type of personally submitting, the pubescent screw is connected to multiple thread's side, the transversal V type of personally submitting of short screw. The utility model discloses a threaded nail simple structure, threaded nail gets into in the fastener easily, the firm in connection of threaded nail and fastener fastens effectually, can extend convenient to use as required.
Description
Technical field
The utility model relates to a kind of fastening piece, refers to a kind of drive screw especially.
Background technique
Existing screw is generally by the tapered screw rod in lower end, overcoat, pad, resilient pad and nut are formed, screw rod puts into pad respectively through after overcoat, resilient pad, finally fix with nut, outer casing internal diameter is maximum between screw rod taper part, between minimum diameter, overcoat lower end is divided into three pieces of slivers, the lower end outer surface of the overcoat of some screw is also provided with the groove that can increase frictional force, during use, elder generation is under wall or bore the individual hole matched with overcoat on the ground, bore dia is approximately 1 cm, then screw is put into, turn nut, screw rod is extracted out, due to the taper that screw rod lower end is up-small and down-big, under the effect of screw rod conical section, three pieces, overcoat lower end sliver can pop outward and pressed against the internal surface in hole, under the effect of frictional force, screw is just fixed on the wall or ground, other article are fixed to facilitate.
Although this type of screw can provide larger intensity, because parts are too many, manufacture cost is high, and installs inconvenient, and particularly under high-lift operation environment, more need one can quick mounting, time and labour saving can provide the drive screw of sufficient intensity at present.In addition at the narrow space that some particular surroundingss cannot operate as spanner, this type of screw uses more inconvenient.Nut and a part of screw rod of this type of screw can be exposed to wall outside, make to install rear outward appearance unsightly, and easily wreck.
Model utility content
The utility model proposes a kind of drive screw, solve drive screw of the prior art with fastening piece in conjunction with unstable problem, complex structure, need defect drive screw could installed of first holing.
The technical solution of the utility model is achieved in that a kind of drive screw, comprise integrated nut, rivet nut and nail tip, described nut and described nail tip lay respectively at the two ends of described rivet nut, described rivet nut is divided into two sections, be respectively epimere and hypomere, described epimere is anodontia district, described hypomere is threaded area, the diameter of rivet nut threaded area is reduced gradually by the upper end of lower end, rivet nut anodontia district to nail tip, the screw thread of described threaded area is multiple thread, described multiple-threaded head number is 4-8 head, described multiple-threaded cross section is V-shaped, described multiple-threaded side is connected with short thread, the cross section of described short thread is V-shaped.
Preferably, the direction cross section of described short thread along nut to nail tip is long-pending to successively decrease successively, and described short thread afterbody is tapered.
Preferably, the middle part of described threaded area is provided with an intersegmental gap section.
Preferably, described nut center is provided with a nut opening, and described rivet nut center is provided with the rivet nut perforate with described nut opening in communication, is provided with internal thread along rivet nut perforate inwall.
Preferably, the height of described threaded area is 10-20mm.
Preferably, the height of described short thread is 2-5mm.
Preferably, the height in described anodontia district is 4-5mm.
The beneficial effects of the utility model are: drive screw structure of the present utility model is simple, and described drive screw easily enters in fastening piece, and being connected firmly of described drive screw and fastening piece, fastening effect is good, can lengthen as required, easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic front view of a kind of drive screw of the utility model embodiment;
Fig. 2 is another schematic front view of a kind of drive screw of the utility model embodiment.
Fig. 3 is the schematic top plan view of the drive screw described in Fig. 1;
Fig. 4 is the schematic top plan view of the drive screw described in Fig. 2.
In accompanying drawing: 1-nut; 12-internal thread; 2-rivet nut; 21-anodontia district; 22-threaded area; 221-multiple thread; 222-short thread; 23-gap section; 3-nail tip.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, shown in 2, a kind of drive screw, comprise integrated nut 1, rivet nut 2 and nail tip 3, described nut 1 and described nail tip 3 lay respectively at the two ends of described rivet nut 2, described rivet nut 2 is divided into two sections, be respectively epimere and hypomere, described epimere is anodontia district 21, described hypomere is threaded area 22, the diameter of rivet nut threaded area 22 is reduced gradually by the upper end of lower end, rivet nut anodontia district to nail tip, the screw thread of described threaded area 22 is multiple thread 221, the head number of described multiple thread 221 is 4-8 head, in accompanying drawing, the head number of multiple thread 221 is 4, the cross section of described multiple thread 221 is V-shaped, the side of described multiple thread 221 is connected with short thread 222, the cross section of described short thread 222 is V-shaped.The V-shaped screw thread that makes of cross section is more sharp, more easy when hammering into body of wall.
