Abstract
The screw structure includes one head, one tail and one thread section. The tail has one flexible clamping hook capable of deforming between the first position and the second position. When the screw is screwed in in the first direction, the clamping hook is forced to deform toward the central axis, and when the screw is screwed off in the opposite direction, the flexible clamping hook is maintained in the first position to push against the combined target, avoiding the separation of the screw structure from the combined target. In addition, the thread section has outer diameter smaller than that of the head.
Description
Technical field
The present invention relates to a kind of screw structural, particularly relate to a kind ofly, and can prevent the screw structural that screw and object come off in order to the object that is spirally connected.
Background technique
At first see also Fig. 1, the figure shows the schematic representation of an existing screw structural.As shown in the figure, general traditional screw structural S mainly comprises a head 101 and a screw section 102, and wherein 102 peripheries, screw section are provided with screw thread 102 '.In existing screw structural S, the user can screw in screw S among the one object P from screw section 102 along a first direction A1, otherwise also can screw S be screwed out in object P along reverse (the second direction A2) of aforementioned first direction A1.
Because existing screw S often screws out and cause coming off along second direction A2 easily, therefore how to design a kind of screw structural that gets loose important topic that begins to become that prevents in object P.
Summary of the invention
In order to improve the shortcoming of above-mentioned existing screw structural, the present invention proposes a kind of screw structural of getting loose of preventing, has a central shaft, in order to the object that is spirally connected.Screw structural of the present invention comprises a head, an afterbody and a screw section.Above-mentioned afterbody has a flexible trip, between a primary importance and a second place, be out of shape, when screw structural when a first direction screws in aforementioned object, flexible trip is subjected to the object compressing and is deformed into the second place by primary importance along rough direction towards central shaft.
Otherwise when screw structural during along the above-mentioned object of reverse back-out of first direction, flexible trip then is positioned at primary importance and props up aforementioned object, separates with object to prevent screw structural.In addition, aforementioned threads portion is positioned between head and the afterbody, and the external diameter of screw section is less than the diameter of head.
In a preferred embodiment, aforementioned first direction is parallel to central shaft.
In the foregoing screw structural, flexible trip limits a depressed part, roughly is parallel to above-mentioned central shaft.
In a preferred embodiment, the width of aforementioned flexible trip is less than the diameter of head.
In a preferred embodiment, when flexible trip was positioned at primary importance, the width of afterbody was greater than the internal diameter of screw section.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly also cooperates appended graphic elaborating.
Description of drawings
Fig. 1 is the schematic representation of existing screw structural;
Fig. 2 a, Fig. 2 b are the schematic representation of screw structural among the present invention;
Fig. 2 c passes the schematic representation of object P for screw structural among the present invention.
Embodiment
At first see also 2a and 2b figure, the figure shows and to prevent the screw structural schematic representation that gets loose among the present invention.As shown in the figure, screw structural 10 of the present invention mainly comprises head 101, screw section 102 and afterbody 103, and wherein 102 surfaces, screw section are provided with screw thread 102 ', and the diameter width of head 101 is greater than the external diameter of screw section 102 and the width of afterbody 103.Shown in Fig. 2 b, above-mentioned screw section 102 is between head 101 and afterbody 103, yet the member that head 101, screw section 102 and afterbody 103 also can be one of the forming, wherein afterbody 103 has a flexible trip 1031, and limits the depressed part 1030 of a thin-and-long.The above-mentioned depressed part 1030 rough central shaft C that are parallel to screw structural 10, flexible thus trip 103 ' can be in the direction distortion of vertical center axis C.
And please consult Fig. 2 c simultaneously, the figure shows the schematic representation that screw structural 10 among the present invention passes an object P.As shown in the figure, in the time will using screw structural 10 to be spirally connected an object P, screw structural 10 can be screwed in and pass the screw P0 of object P from afterbody 103 along a first direction A1, wherein first direction A1 is parallel to aforementioned central shaft C.
In particular, in the process of DRIVE SCREWS structure 10, owing to afterbody 103 must pass the compressing that screw P0 is subjected to screw P0 inwall, this moment, aforementioned flexible trip 1031 will be from a primary importance 1031 ' towards the direction distortion near central shaft C, and move to a second place 1031 " (position shown in the dotted line), successfully screw in upward in the screw P0 so that the screw section of below 102 is sustainable.Wherein, because flexible trip 1031 has elasticity, therefore after the afterbody 103 of screw structural 10 passes the screw P0 of object P, original primary importance 1031 ' will be returned back to automatically.
Shown in Fig. 2 c, after screw structural 10 screws in and passes object P, the flexible trip 1031 of afterbody 103 returns back to aforementioned primary importance 1031 ' immediately, therefore when will be on the contrary along a second direction A2 (first direction A1 oppositely) during with screw structural 10 back-out object P, flexible trip 1031 will prop up the surface of object P and can prevent effectively that screw structural 10 from coming off.In the present embodiment, when flexible trip 1031 was positioned at primary importance 1031 ', the width D of afterbody 103 was greater than the inner diameter d of screw section 102.
In sum, the present invention is provided with flexible trip 1031 structures at screw structural afterbody 103, because flexible trip 1031 has elasticity, not only can not influence the action that screw is screwed in object, the shortcoming that comes off easily in the time of can avoiding simultaneously screw structural 10 to comply with effectively against the direction turn, so the present invention can be widely used in anti-loose screw or the rotating Knob mechanisms.
Though disclose as above with preferred embodiment by the present invention; yet it is not in order to limiting scope of the present invention, anyly is familiar with this operator, without departing from the spirit and scope of the present invention; can do some change and retouching, so protection scope of the present invention should be with being as the criterion that claim was defined.
