Abstract
The utility model relates to an embedded screw, including the head and with the pole portion that the head is connected the outer diametral plane of head is close to head terminal surface department is equipped with the recess, be equipped with the elastic expansion arm component in the recess. The utility model discloses an embedded screw, during the equipment, it is downthehole together to twist the head that the circuit board reserved with screw head together with pole portion, and the flexible arm in the screw head stretches out, push up tightly downtheholely at the head, makes thinner that screw head can do, and fastening that screw pole portion does shorter the time is effectual, does not take the cell -phone inner space, makes cell -phone thickness approach more.
Description
Technical field
The utility model is related to a kind of screw, and in particular to a kind of embedded screw, belongs to technical field of fastening.
Background technology
Mobile phone at present on the market is multifarious, and with the development of mobile phone, the parts of interior of mobile phone are also towards fine, jail
Gu, the aspect such as durable development, nut screw is with many in mobile phone, and assist side surface is used nut more, and interior of mobile phone
Spaces compact, the nut outside too many exposed assist side causes mobile phone without the thinner development of normal direction, and if reducing the thickness of nut,
Then contact surface reduces between screw and nut, does not have good fixation.
Utility model content
The purpose of this utility model is to overcome the shortcomings of that prior art is present, there is provided a kind of attractive in appearance, floor space it is small and
The good embedded screw of fastening effect.
To reach above-mentioned purpose, the technical solution adopted in the utility model is:A kind of embedded screw, including head and with
The bar portion of the head connection, groove is provided with the head outer diameter face at the head end;Set in the groove
Flexible flexible arm component.
Preferably, the elastic telescopic arm component has two groups and is symmetrical arranged.
Preferably, the groove inner wall is provided with bayonet socket;The elastic telescopic arm component includes spring and telescopic arm;It is described
Spring one end is connected with the groove, and the other end is connected with the telescopic arm;The telescopic arm is provided with and matches with the bayonet socket
The projection that conjunction is used.
Preferably, the head periphery is provided with annular knurl;The bar portion has screw thread.
Preferably, a diameter of 1-10mm of the head;Thickness is 1-3mm;The bar portion is 1-10mm.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art:
Embedded screw of the present utility model, during assembling, is together screwed into what wiring board was reserved by screw head together with bar portion
In head bore, the telescopic arm in screw head stretches out, and holds out against in head bore, allows thinner, the lead screw that screw head does
Portion do it is shorter while fastening effect it is good, be not take up interior of mobile phone space, allow mobile phone thickness more thin.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings:
Accompanying drawing 1 is the structural representation of embedded screw of the present utility model;
Accompanying drawing 2 is the elastic telescopic arm component expanded configuration schematic diagram of embedded screw of the present utility model;
Wherein:1- heads;2- bar portions;3- grooves;4- bayonet sockets;31- springs;32- telescopic arms;33- projections.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in accompanying drawing 1,2, a kind of embedded screw described in the utility model, including head 1 and be connected with head 1
Have threaded bar portion 2, two groups of symmetrically arranged grooves 3, the inwall of groove 3 are provided with head end in the outer diameter face of head 1
It is provided with bayonet socket 4;It is respectively provided with including spring 31 and telescopic arm 32 in groove 3;The one end of spring 31 is connected with groove 3, another
End is connected with telescopic arm 32;Telescopic arm 32 is provided with the projection 33 being used in combination with bayonet socket 4.Work of the telescopic arm 32 in spring 31
Can freely be stretched in groove 3 under firmly, when needing to be contracted in groove 3, realize positioning by bayonet socket 4.
Twisted for convenience of hand, annular knurl is provided with the periphery of head 1.
When mobile phone component is installed, head diameter is 3mm;Thickness is 2mm;The bar portion is 3mm;During assembling, head 1 connects
Together it is screwed into the reserved head bore of wiring board with bar portion 2, the telescopic arm 32 in head 1 stretches out, and holds out against in head bore, makes spiral shell
Silk head can do it is thinner, screw bar portion do it is shorter while fastening effect it is good, be not take up interior of mobile phone space, make mobile phone
Thickness can be more thin.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.All use equivalents or equivalence replacement and the technical scheme that is formed, all fall within the utility model rights protection scope it
It is interior.
