Description
Technical field
The utility model relates to a kind of structure of spiral shell spare, particularly relates to a kind of screw terminal member.
Background technique
In the more and more flourishing society of science and technology, it is more and more littler that electronic component is manufactured, to adapt to the demand of compact electronic equipment.Therefore, the screw that generally is commonly used to lock these electronic components is also done littler and littler along with dwindling of electronic component size.Yet, because therefore dwindling of screw size make screw terminal and the bottle opener difficulty when chimeric increase many.
General public screw kenel can be divided into yi word pattern caulking groove and cross caulking groove.Yet the screw terminal of yi word pattern caulking groove or cross caulking groove all has a difficulty, promptly when bottle opener and screw terminal are entrenched togather mutually, because the degree of depth of caulking groove is limited, in case therefore during quick rotation, make that easily bottle opener departs from screw terminal, thereby the phenomenon that slippage takes place or depart from.
If but bottle opener departs from the phenomenon of screw terminal when occurring in fixedly electronic component (for example locking the sink of CPU (central processing unit)), this not only can cause the situation of bottle opener slippage, more make the bottle opener after the slippage strike peripheral electronic component, cause the damage of peripheral electronic component, and then cause the increase of cost.
Therefore, be necessary to provide a kind of screw terminal of improved type, to reduce the phenomenon of bottle opener slippage.
Novel content
This novel purpose just is to provide a kind of screw, in order to reduce the phenomenon of bottle opener slippage.
This another novel purpose is to provide a kind of screw terminal member, makes bottle opener be difficult for departing from screw terminal when rotating, thereby reduces the phenomenon of sliding tooth.
According to this novel above-mentioned purpose, a kind of screw is proposed.Described screw comprises bar portion, flange, groove, caulking groove and screw rod.Described groove is positioned at the top of bar portion, and caulking groove is arranged with the bottom center in groove, and described flange is positioned at the outer periphery place of groove, and screw rod is positioned at the lower end of bar portion.
According to this novel above-mentioned purpose, a kind of screw terminal member is proposed, described member comprises a screw terminal, a groove, is positioned on the described screw terminal, a caulking groove, is arranged with a bottom center and a flange in described groove, is positioned at the outer periphery of described groove.
According to this novel preferred embodiment, the kenel of described caulking groove is preferably yi word pattern, cross, interior hexangle type, Y-shaped or other is applicable to the kenel of caulking groove.
In this novel preferred embodiment, screw rod is fixed on the bottom of bar portion, and the surface of screw rod has screw thread.Perhaps, also can make the surface of bar portion have screw thread, and the preferable shape of the bar portion of this moment be circular according to demand with the object that is spirally connected.
Screw is to make caulking groove and bottle opener chimeric mutually by groove, so that the follow-up action that is spirally connected.Described groove is to be used for increasing the degree of depth that bottle opener is embedded in screw, makes bottle opener be not easy to depart from screw terminal when quick rotation, so just can improve the phenomenon of bottle opener slippage.
Therefore, by above-mentioned novel preferred embodiment as can be known, this is novel to be to utilize groove to increase the degree of depth that bottle opener is embedded in screw.Therefore when screw during, can improve the phenomenon of bottle opener slippage by the design of groove in fast turn-around.In addition, this novel bottle opener that can also make is difficult for departing from screw terminal, thereby the phenomenon that reduces sliding tooth takes place.
Description of drawings
For making this novel above-mentioned and other purpose, feature, advantage and embodiment can more obvious easy to understand, be described with reference to the accompanying drawings as follows.
Fig. 1 is the schematic representation of expression according to a kind of screw terminal member of this novel preferred embodiment; And
Fig. 2 is the schematic representation of expression according to a kind of screw terminal member of this novel another preferred embodiment.
Embodiment
This novel screw terminal member that a kind of improved type is provided, it adds a sidewall to form a groove above the caulking groove place, be embedded in the degree of depth of screw terminal in order to increase bottle opener, and then improve the phenomenon of bottle opener slippage.Below will clearly demonstrate this novel spirit with drawings and detailed description, those skilled in the art can be by the technology change and the modification of this novel institute teaching after understanding this novel preferred embodiment, and it does not break away from this novel spirit and scope.
With reference to Fig. 1, it is the schematic representation of expression according to a kind of screw terminal member of this novel preferred embodiment.Screw 100 in Fig. 1 comprises bar portion 102, groove 104, caulking groove 106, flange 110 and screw rod 108.Wherein, groove 104 is positioned at the top of bar portion 102, and caulking groove 106 is arranged with in the bottom center of groove 104, and flange 110 is positioned at the outer periphery place, top of groove 104, and screw rod 108 is positioned at the lower end of bar portion 102.
The kenel of caulking groove 106 is preferably yi word pattern, cross, interior hexagonal, Y-shaped or other is applicable to the kenel of caulking groove.In this novel preferred embodiment, caulking groove 106 is preferably cross caulking groove, but is not limited thereto kenel.
The shape of bar portion 102 is preferably circle, triangle, square, hexagon or other shape that is suitable for.In this novel preferred embodiment, bar portion 102 is preferably circular pin portion, but is not limited thereto shape.
In this novel preferred embodiment, screw rod 108 is fixed on the bottom of bar portion 102, and the surface of screw rod 108 has screw thread.With reference to Fig. 2, perhaps can also make the surface of bar portion 102 have screw thread 109, and the preferable shape of the bar portion 102 of this moment be circular according to demand with the object that is spirally connected.
The preferred material of screw 100 is that iron, stainless steel, metal, alloy genus, carbon steel, plastics or other are applicable to the material of screw.
In this novel preferred embodiment, the preferred depth of caulking groove 106 is 1.2 centimetres, and the preferred depth of groove 104 is 1.0 centimetres, and the diameter of groove 104 is preferably 4.2 centimetres, and the diameter of flange 110 is preferably 6.9 centimetres.This is novel not to exceed with this embodiment, various possible sizes all can be applicable to this novel in.
In this novel preferred embodiment, screw 100 is to make caulking groove 106 and bottle opener chimeric mutually by groove 104, is beneficial to the follow-up action that is spirally connected.Groove 104 is used for increasing the degree of depth that bottle opener is entrenched in screw 100, makes bottle opener be not easy to depart from screw terminal when quick rotation.Can improve the phenomenon of bottle opener slippage like this.
Therefore, by above-mentioned novel preferred embodiment as can be known, this is novel to be to utilize groove to increase the degree of depth that bottle opener is embedded in screw.Therefore when screw during, can improve the phenomenon of bottle opener slippage by the design of groove in fast turn-around.In addition, this novel bottle opener that can also make is difficult for departing from screw terminal, thereby the phenomenon that reduces sliding tooth takes place.
Though this is novel own with the preferred embodiment announcement, it is not novel in order to limit this, and any those skilled in the art not breaking away from this novel spirit and scope, can make various changes and retouching.Therefore this novel protection domain is defined with accompanying Claim.
