Abstract
The utility model discloses a kind of double end self tapping part, including screw, screw two ends are connected with different component respectively, and for being linked together by different components, screw two ends are equipped with tapping screw thread.Using the double end self tapping part of above technical scheme, in use, first screw in a component by one end of screw, tapping screw thread can form corresponding thread in component and coordinate with it fixing during screwing in.One end of screw screw in place after, then another component is spun fixing with the other end of screw in an identical manner.This connection fixed form is the most simple to operate, and consumptive material is few and low cost, is especially suitable for batch production.
Description
Technical field
This utility model relates to mechanical fastener, particularly to a kind of double end self tapping part.
Background technology
It is known that self-tapping screw generally refer to tip, coarse thread, wood screw that quality is harder.Self-tapping screw is one
Kind with the screw of drill bit, by special electric tool or screwdriver construction, boring, tapping, fix, lock and once complete.
Self-tapping screw is widely used in indoor, and screw head is often exposed to outdoor.The most commonly used self-tapping screw is all with one
Individual screw head and a screw mandrel with spiral thread, the referred to as self-tapping screw of single head, be mainly used in some relatively sheet member
Connection with fixing, such as color steel and the connection of color steel, color steel and purlin, the connection etc. of wall beam.The self tapping spiral shell of single head
Though its performance is good during silk application, but range of application is the most necessarily limited to, and in the decoration process of house, self-tapping screw is often appeared
Beautiful decoration can be affected.
Appear for solution self-tapping screw and affect the problem of beautiful decoration, manufacturing furniture, indoor and outdoor decoration or building exhibition
During the structural member such as frame, panel, it usually needs be fixed up being connected between timber with timber.Conventional method is to bore on timber
Hole, tumbles in nut.Again bolt is screwed in.This connection fixed form operation is complicated, and consumptive material is many and cost high.
Utility model content
The purpose of this utility model is to provide a kind of double end self tapping part.
According to an aspect of the present utility model, it is provided that a kind of double end self tapping part, including screw, screw two ends respectively with
Different component is connected, and for being linked together by different components, screw two ends are equipped with tapping screw thread.
Use the double end self tapping part of above technical scheme, in use, first one end of screw is screwed in a component, from
Tapping can form corresponding thread in component and coordinate with it fixing during screwing in.One end of screw screws in
After in place, then another component is spun fixing with the other end of screw in an identical manner.This connection fixed form is not
The most simple to operate, consumptive material is few and low cost, is especially suitable for batch production.
In some embodiments, the precession direction of the tapping screw thread at screw two ends is identical.Screw two ends tapping screw thread
Rotation direction Main Function in the same direction has:
(1), when being used in main equipment, needing to install adnexa, owing to adnexa is often dismounting, screw thread can wear and tear or damage
Bad, use this screw replacing can be very convenient；
(2), for component thickness very greatly, when screw length is the longest, manufacture more convenient；
(3), use aid when screwing in, screw thread can be directly utilized aid is temporarily connected with this screw
Connect, it is not necessary to special design.
In some embodiments, component is wood furniture component.
In some embodiments, the tapping screw thread at screw two ends is identical.
In some embodiments, top, screw two ends is most advanced and sophisticated.Thus, centering and the self tapping effect of screw are more preferable.
In some embodiments, also including that sleeve part, sleeve part one end are provided with sleeve pipe, internal surface of sleeve pipe is provided with and self tapping spiral shell
The thread that stricture of vagina matches.
In some embodiments, the other end that sleeve part is relative with sleeve pipe also has clamp holder, and clamp holder can be by electric drill chuck
Or electric screw driver grips.Thus, this double end self tapping part can use the electric tool with chuck to install, more just
Just.
In some embodiments, sleeve pipe the inner is provided with the step surface stoping screw to continue inside precession.Thus, may be used
With the dismounting inconvenience avoiding screw excessively deeply to cause in sleeve pipe.

Fig. 3 is the attachment structure schematic diagram of the screw shown in Fig. 1 and component.
Fig. 4 is the installment state schematic diagram of the screw shown in Fig. 1 and component.
Fig. 5 is the enlarged drawing of part shown in A in Fig. 4.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1 to Fig. 4 show schematically show a kind of double end self tapping part according to a kind of embodiment of the present utility model.As
Shown in figure, this device includes screw 1 and sleeve part 2.
Wherein, screw 1 two ends are connected with different component 3 respectively, for being linked together by different components 3.
In the present embodiment, component 3 is wood furniture component.
Screw 1 two ends are equipped with tapping screw thread 11.
The precession direction of the tapping screw thread 11 at screw 1 two ends is identical.
In the present embodiment, the tapping screw thread 11 at screw 1 two ends is identical.
Top, screw 1 two ends is most advanced and sophisticated.
Sleeve part 2 one end is provided with sleeve pipe 22.
Sleeve pipe 22 inwall is provided with the thread 221 matched with tapping screw thread 11.
The other end that sleeve part 2 is relative with sleeve pipe 22 also has clamp holder 21.Clamp holder 21 can be by electric drill chuck or electronic
Sub-grips.
Sleeve pipe 22 the inner is provided with the step surface 222 stoping screw 1 to continue inside precession.
Use the double end self tapping part of above technical scheme, in use, first the one end using sleeve part 2 screw 1 is screwed in
In one component 3, tapping screw thread 11 can form corresponding thread during screwing in component 3 and coordinate with it solid
Fixed.One end of screw 1 screw in place after, then reversely rotate sleeve part 2, screw 1 exited from the sleeve pipe 22 of sleeve part 2
Come.Finally again another component is spun fixing with the other end of screw in an identical manner.This connection fixed form is not only
Simple to operate, consumptive material is few and low cost, is especially suitable for batch production.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into this practicality
Novel protection domain.
