Specific embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, below will be to technology of the present utility model
Scheme is described in detail.Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not before creative work is made
Resulting all other implementation method is put, the scope that the present invention is protected is belonged to.
A kind of double-headed spike, as shown in accompanying drawing 1 and accompanying drawing 4, the double-headed spike includes screw division 1, countersunk head portion 2 and binding part 3, institute
Stating screw division 1 includes pointed nose 11 and threaded portion 12, and the countersunk head portion 2 is provided with mounting groove 21；The binding part 3 includes some
Binding 31, the pointed nose 11 is arranged at one end of threaded portion 12, and countersunk head portion 2 is arranged at the other end of threaded portion 12；The peace
Tankage 21 and the threaded portion 12 are respectively arranged at the two sides in the countersunk head portion 2, and the binding 31 and the mounting groove 21 are set
In the same face in the countersunk head portion 2.
The screw division 1 and the binding part 3 connect two objects respectively, and the countersunk head portion 2 connects the screw respectively
Portion 1 and the binding part 3.The threaded portion 12, it is necessary to be stuck in by screwdriver on mounting groove 21, is screwed into during installation
After needing on object to be mounted, then binding part 3 is pressed into other objects, completes connection.
For convenience in the object for entering needs connection of the double-headed spike threaded portion 12, the screw thread of the threaded portion 12 is certainly
Tapping, using more convenient.
Threaded portion 12 is screwed into for convenience, and the mounting groove 21 is arranged at the center of the one side of countersunk head portion 2, that is, install
The center of groove 21 and the tip of pointed nose 11 are more laborsaving during installation on same straight line.
Compared to yi word pattern mounting groove 21, cross mounting groove 21 is more often used, and during use, more difficult damage
It is bad, therefore the mounting groove 21 is cross mounting groove 21.One flute length of the cross mounting groove 21 a, groove is short.Adopt
Such structure design is used, mounting groove 21 can not only be fastened by slotted point screwdriver, and can be tight by Philips screwdriver
Gu, versatility is stronger.
In order to prevent binding 31 from departing from from the object for entering, the binding 31 is provided with some raised 311.When binding 31
After in into object, raised 311 can be stuck in nail well.Compared to single isolated projection 311, annular protrusion 311
It is stuck in nail tightlier, adhesive force is bigger, therefore, described raised 311 is annular protrusion 311.
As shown in Figure 2, described raised 311 have two inclined-planes, and the angle near an inclined-plane in the countersunk head portion 2 is big
Inclined to the countersunk head portion 2 in the angle on another inclined-plane, and two inclined-planes.Using such structure design, binding 31 more holds
Easily enter object, such as in plank.
The binding 31 can have multiple, and such as two, three, specific number can be calculated according to design strength, with regard to one
As for four bindings 31 can proof strength, as shown in Figure 3, be evenly distributed in around the mounting groove 21.
In order to ensure double-headed spike structural strength in itself, the double-headed spike is one-shot forming.Prevent during use
Situations such as appearance fractures.
Embodiment one
A kind of double-headed spike, including screw division 1, countersunk head portion 2 and binding part 3, the screw division 1 include pointed nose 11 and screw thread
Portion 12, the countersunk head portion 2 is provided with cross mounting groove 21；The binding part 3 includes four bindings 31, and the pointed nose 11 is set
In one end of threaded portion 12, countersunk head portion 2 is arranged at the other end of threaded portion 12；The mounting groove 21 and the threaded portion 12 are distinguished
The two sides in the countersunk head portion 2 is arranged at, the binding 31 and the mounting groove 21 are arranged at the same face in the countersunk head portion 2.Institute
Threaded portion 12 is stated for tapping screw thread, the binding 31 is provided with some annular protrusions 311, described raised 311 have two inclined-planes,
Incline to the countersunk head portion 2 near the angle of the angle on inclined-plane more than another inclined-plane in the countersunk head portion 2, and two inclined-planes
Tiltedly.
It is wall if necessary to what is installed as shown in Figure 5 when using, is punched on present wall is needed, then will enters
In wall expansion micelle load hole, then through threaded portion 12 by entering wall expansion glue intragranular on screwdriver, if necessary to be arranged on wood
Between plate, then can be thread directly into plank by screwdriver, it is easy to use.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art the invention discloses technical scope in, can readily occur in change or replace
Change, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be wanted with the right
The protection domain asked is defined.
