Abstract
The utility model discloses a screw cap comprising a cap surface, wherein the cap surface is provided with clamping ribs; a convex rib post is arranged on the side wall of each clamping rib; at least four clamping ribs are provided for improving reliability; each clamping rib is arranged at intervals; and the convex rib is arranged on the side wall of each clamping rib. The screw cap is widely applied to consumer electronic products, such as cellphones, digital cameras and the like, and has high reliability and is not easy to loose.
Description
Technical field
The utility model relates to a kind of screw cap, specifically a kind of screw cap that is mainly used on the consumption electronic products such as mobile phone, digital camera.
Background technology
The material of mobile phone back cover generally is an engineering plastic PC now, makes whole mobile phone assembling firm, and back cover is provided with screw cap.The reliability of screw cap is generally loaded onto behind the back cover the whether loosening easily measurement that drops out with screw cap.
Screw cap on the present mobile phone is two kinds of material structure forms normally, and a kind of is the screw cap of silica gel form, and a kind of is the version of dijection material.The screw cap outward appearance that silica gel material is processed is plain, and general comparatively high-grade mobile phone can not adopt.Another kind is the version of dijection material; The material that the material of dijection structure outward appearance uses PC engineering plastics and back cover to match is used flexible glue TPU, is guaranteeing under the goodlooking form like this; Guaranteed product reliability; But the screw cap of this structure, mfg. moulding die version more complicated, and relatively more expensive.
Summary of the invention
The technical problem that the utility model will solve provides a kind of screw cap that is mainly used on the consumption electronic products such as mobile phone, digital camera, and reliability is high, appearance looks elegant.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of screw cap comprises capping, and said capping is provided with the card muscle, and this card muscle sidewall is provided with protruding muscle position.
Said card muscle is at least four, and is provided with at interval between each card muscle, is provided with protruding muscle position on each card muscle sidewall.
The said muscle position and the card muscle structure that is formed in one that is arranged on the capping.
Zhu said cover face and card, tendons bits are made of PC plastic.
The utility model is widely used on the consumption electronic products such as mobile phone, digital camera, has both guaranteed the reliability of screw cap, can guarantee the attractive in appearance of outward appearance again.
Description of drawings
Accompanying drawing 1 is the utility model perspective view.
Embodiment
For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, a kind of screw cap comprises capping 1, and said capping 1 is provided with card muscle 2, and these card muscle 2 sidewalls are provided with protruding muscle position 3.In order to guarantee reliability, card muscle 2 is at least four, and is provided with at interval between each card muscle 2, promptly has the gap between each card muscle 2, is provided with protruding muscle position 3 on each card muscle 2 sidewalls.Cover surface 1 and Card Zhu 2, bit 3 ribs are made of PC plastic.In addition, for the ease of processing, card muscle 2 and muscle position 3 structure that is formed in one.
When the utility model is applied on the mobile phone back cover; Be loaded on the corresponding screw hole on the mobile phone back cover; Realize interference fit through card muscle and the muscle position of card on the muscle with screw hole, optimum is provided with four card muscle, is equivalent to four cantilever beams whiles each other to the center power of having an effect; The frictional force that each card muscle produces to the pressure at screw hole center makes whole screw cap being fixed in the screw hole tightly, prevents effectively that screw cap is loosening to drop out.
The foregoing description is the utility model preferred embodiment; In addition, the utility model also has other implementations, need to prove; Under the prerequisite of the inventive concept that does not break away from the utility model, any conspicuous replacement is all within the protection range of the utility model.
