Abstract
The utility model discloses a pagoda formula fastener, solve self -tapping screw rotatory in -process exist the driving moment big, bore get the difficulty and fixed after with the cooperation of carrier not hard up problem easily, influenced fastener and the firm degree of carrier complex. Its technical scheme main points are including the body of rod, are the cone form, body of rod top is provided with multiple tooth stiff end, multiple tooth stiff end includes the main tooth that lies in its center and sets up the side tooth in main tooth both sides that it is outside around being provided with the toper screw of following the even increase of body of rod top to bottom tooth root to surround the body of rod. Reached the side tooth after screwing, the side tooth of main tooth both sides has the chucking in the carrier, avoids the fastener to take place the ascending skew in footpath, and difficult not hard up, the outside of the body of rod is provided with conical screw in addition. Conical screw thread can be in the self tapping the wrong income resistance of toper screw thread less, crescent screw thread has the difficult radial deflection that takes place after can screwing up moreover again, fastens more firm effect.
Description
Technical field
The utility model relates to hook field, and more particularly, it relates to a kind of pagoda type fastening piece.
Background technique
Fastening piece be fastenedly connected with one connect a kind of mechanical parts very widely, usually compare and common are bolt and screw, when being fixed to some carriers, (such as wooden three-ply board or wad) just needs tapping screw, improve utilization efficiency and fixing fastness, but tapping screw also exist in rotary course driving moment large, drill through difficulty and fixing after with carrier coordinate the problem easily loosened, have impact on the firmness of fastening piece and carrier combination.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide one to be, and in carrier combination, driving moment reduces, and a kind of pagoda type fastening piece of good fixing effect.
For achieving the above object, the utility model provides following technological scheme: a kind of pagoda type fastening piece, comprises the body of rod, in cone shape; Described body of rod top is provided with multiple tooth fixed end, and described multiple tooth fixed end comprises the main tooth being positioned at its central position and the side tooth being arranged on main tooth both sides, is surrounded with around the body of rod outside tapered thread evenly increased from body of rod top to bottom tooth root.
Further, in the described body of rod, be provided with the hollow cavity running through body of rod top to bottom, the inwall of described hollow cavity is provided with some fixed strips.
Further, described fixed strip is everywhere and is uniformly set at hollow cavity inwall with body of rod center.
Further, the bottom of the described body of rod is provided with base.
The beneficial effects of the utility model are, by being provided with multiple tooth fixed end, multiple tooth fixed end comprises main tooth and side tooth, main tooth is mainly used in its effect when attacking brill fastening piece, and side tooth is after screwing, and in carrier, the side tooth of main tooth both sides has clamping, by instrument, multiple tooth fixed end is strutted after fixing, avoid the skew in fastening piece generation radial direction, not easily loosen, and the outer installment of the body of rod there is the screw thread of taper.The screw thread of taper can when self tapping tapered thread to be screwed into resistance less, and the screw thread increased gradually after can tightening again has and not easily radial deflection occurs, fastening more firmly effect.

Embodiment
Referring to figs. 1 through Fig. 4, a kind of pagoda type fastening piece of the utility model is described further.
A kind of pagoda type fastening piece, comprise the body of rod 1, the body of rod 1 in coniform, the bottom of the body of rod 1 is one end that diameter is larger, the top of the body of rod 1 is provided with multiple tooth fixed end 2, multiple tooth fixed end 2 comprises the main tooth 21 being positioned at its central position and the side tooth 22 being arranged on main tooth 21 both sides, the height of main tooth 21 is higher than the height of side tooth 22, the shape of main tooth 21 and side tooth 22 is triangle, main tooth 21 is mainly used in its effect when attacking brill fastening piece, side tooth 22 is after screwing, in carrier, the side tooth 22 of main tooth 21 both sides has clamping, by instrument, multiple tooth fixed end 2 is strutted after fixing, avoid the skew in fastening piece generation radial direction, not easily loosen.
Be surrounded with the tapered thread 3 evenly increased from the body of rod 1 top to bottom tooth root around the body of rod 1 outside, the number of turns of tapered thread 3 is three circle to four circles, and the pitch of tapered thread 3 is between 7mm to 8mm.The outer installment of the body of rod 1 has the screw thread of taper.The screw thread of taper can when self tapping tapered thread 3 to be screwed into resistance less, and the screw thread increased gradually after can tightening again has and not easily radial deflection occurs, fastening more firmly effect.
The hollow cavity 4 running through the body of rod 1 top to bottom is provided with in the body of rod 1, the inwall of described hollow cavity 4 is provided with some fixed strips 42, the shape of fixed strip 42 is triangle, highly for extend to top from bottom 1/3rd, there are four and centered by the body of rod 1, be uniformly set at the inwall of hollow cavity 4, fixed strip 42 bottom is also provided with four reinforcing strip 41, reinforcing strip 41 cross section is ring-type, can match with fixed strip 42 in the gap had between four cutter heads that just can realize common Phillips screwdriver, when carrying out screwing tight pagoda type fastening piece, it is unexpected except operation can be carried out with specific instrument, can also operate with the Phillips screwdriver of corresponding size, like this with regard to easy-to-operat, facilitate fastening.
Top is run through to bottom because hollow cavity 4 runs through the body of rod 1, so multiple tooth abutting end 2 is provided with breach 5 with the wherein side of top junction surface, so just achieve carry out fastening after, a fixed strip can be stretched into from the bottom of the body of rod 1, fixed strip is stretched out from top, owing to top being provided with breach 5, so fixed strip can be clamped on top end, this means of fixation is well suited for fastening piece to be fixed on the carrier on the tops such as ceiling board, the other end of fixed strip just can provide the function hanging and taking thing, so just achieve and can hang some things on the ceiling by fastening piece.
The bottom of the body of rod is provided with the end 6, the diameter of the bigger and maximum screw thread of diameter of base 6, the tapered shape of base 6.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
Although more employ the terms such as the body of rod, multiple tooth fixed end, main tooth, side tooth, tapered thread, hollow cavity, reinforcing strip, fixed strip, breach, base herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
