Description

Portable terminal lanyard device

Technical field

The utility model relates to portable terminal, specifically, relates to a kind of portable terminal lanyard device.

Background technology

For convenience of purposes such as the user carry, on the shell of existing mobile phone, PDA portable terminals such as (personal digital assistants), generally all be useful on the lanyard hole that connects lanyard.Fig. 1 and Fig. 2 show a kind of lanyard hole and are positioned at position signal on the phone housing, wherein Fig. 1 is the mobile phone vertical view, the lanyard hole is at the opening 20 at mobile phone top, be positioned at the position of mobile phone top casing 10 near the mobile phone back side, this is owing to the back side or the side that generally lanyard are through mobile phone, not influence the attractive in appearance of mobile phone front as far as possible.The position signal in lanyard illustrated in figures 1 and 2 hole is for being through lanyard the embodiment at the mobile phone back side.

Fig. 2 is the mobile phone rearview, and another opening 30 in lanyard hole is positioned on the mobile phone back side shell 80.The user passes two openings in lanyard hole successively with lanyard, and lanyard is tied up on the rope-hanging column 40, and like this, the user just can pass through lanyard, carries mobile phone easily.

Rope-hanging column 40 not only can connect lanyard, have now a lot of specially at the accessory suspension member of mobile phone to decorate mobile phone.Because the lanyard hole is subject to spatial limitation, be processed with than large space and can't design, when lanyard or these accessory suspension members are installed, can not easily lanyard or suspension member be passed the lanyard hole to tie up on the mobile phone rope-hanging column, usually more have and finish connection by means of instruments such as fine wires.

The utility model content

Technical problem to be solved in the utility model is to be to provide a kind of mobile phone lanyard device, can easily the mobile phone lanyard be tied up on the mobile phone.

In order to solve the problems of the technologies described above, the utility model provides a kind of portable terminal lanyard device, is embedded with a roller bearing on mobile terminal shell, and cover one roller leaves the slit between described roller and the described mobile terminal shell on the described roller bearing.

In the aforesaid portable terminal lanyard device, between described roller bearing and the described roller, can be matched in clearance.

In the aforesaid portable terminal lanyard device, the exterior contour of described roller cross section can comprise circle, triangle, quadrangle or polygon.Further, described triangle can comprise the fillet triangle; Described quadrangle can comprise the fillet quadrangle; Described polygon can comprise the fillet polygon.

In the aforesaid portable terminal lanyard device, on the described roller symbol can be arranged.Further, described symbol can comprise character.Further, described character can comprise the trade mark of described portable terminal, and/or brand mark.

Embodiment

Describe execution mode of the present utility model in detail below with reference to drawings and Examples, how the application technology means solve technical problem to the utility model whereby, and the implementation procedure of reaching technique effect can fully understand and implements according to this.

Below be that example explanation the utility model is applied to the technical characterstic on the portable terminal with the mobile phone.Mobile phone lanyard or ornamental article and hanging piece (below be referred to as lanyard) are difficult to tie up to the reason on the mobile phone rope-hanging column, mainly be that space, lanyard hole is narrow and small, and lanyard can not be straight pass the lanyard hole, but need in the lanyard hole, turn round, lanyard hole as depicted in figs. 1 and 2, lanyard just need be converted into 90 degree in narrow and small lanyard hole.

The utility model is considered above-mentioned reason, following solution has been proposed: as shown in Figure 3, the utility model embodiment is positioned at the mobile phone top, rope-hanging column shown in Figure 1 40 is improved to lanyard roller bearing 50 among Fig. 3, roller bearing 50 is embedded on the phone housing, roller 60 of cover on roller bearing 50, lanyard roller bearing 50 is a matched in clearance with roller 60, scroll wheel 60 very freely.Like this, when being tied to lanyard on the mobile phone, by means of the rolling of roller 60, lanyard just can pass the slit 70 between roller 60 and the phone housing easily.

The cross section of roller 60 shown in Figure 3, exterior contour are circular.In the middle of other embodiment, the exterior contour of roller cross section also can be a triangle, quadrangle, even polygon.Such as triangle, quadrangle or polygonal corner angle can be the band certain radian, that is to say, the exterior contour of roller cross section can be band rounded triangle, quadrangle or a polygon.

Because roller has been arranged, can reduce lanyard directly with the friction of mobile phone rope-hanging column, avoided causing rubbing lanyard owing to frequent friction, so also prolonged the useful life of mobile phone lanyard.

In order to deepen the portable terminal brand, in the middle of other embodiment of the present utility model, even on roller, process trade mark, the Logo (brand mark) of terminal brand, even other there is the symbol of specific meanings in client's image in the heart.

Though the disclosed execution mode of the utility model as above, the execution mode that described content just adopts for the ease of understanding the utility model is not in order to limit the utility model.Technical staff under any the utility model in the technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do a little change and retouching what implement in form and on the details; but scope of patent protection of the present utility model, still must with appending claims the person of being defined be as the criterion.
