Description

The structure-improved of USB displacement disc

Technical field

The utility model relates to a kind of USB displacement disc, especially refers to a kind of structure-improved of avoiding the USB displacement disc that over cap loses.

Background technology

Along with development in science and technology is maked rapid progress, except designing notebook computer computing machine can be carried, more develop and portable hard disk, only data are carried, its weight and notebook computer significantly reduce by contrast, have more convenience, in addition, the displacement disc that only has an access facility can't satisfy popular demand, listens to the music, function such as recording adds up one after another, makes the use aspect of displacement disc more universal.

Displacement disc uses the USB joint to be connected with computing machine more at present, but the volume of displacement disc is very compact, and the over cap of protection USB joint is littler, very easy losing.In the prior art, over cap is except with the displacement disc housing separates, also have two kinds of methods that over cap is connected with displacement disc to avoid over cap to lose, one as shown in Figure 1, it between USB joint and the internal memory elasticity circuit, compress this elasticity circuit the USB joint is hidden in the displacement disc housing, again the USB joint is released outside the housing during use, but the method easily makes elasticity circuit fatigue impaired; Other method as shown in Figure 2; over cap is designed to turning; utilize at least one connecting link to be connected between this over cap and the displacement disc housing; after over cap drawn back; turning half-turn blocking is fixed on the rear end of displacement disc housing; lose to avoid over cap; but the method is anti-easy not as first method in the use; and thin connecting link also has the possibility of fracture to exist; over cap is separated with housing; and often over cap is connected on the length that the housing rear end can increase displacement disc, pegs graft when displacement disc and can cause user's inconvenience when using on computers, and the situation of displacement disc for example takes place to kick because of carelessness.

Therefore, the utility model proposes a kind of structure-improved of USB displacement disc at the problems referred to above, effectively to overcome above-mentioned defective.

The utility model content

Fundamental purpose of the present utility model provides a kind of structure-improved of USB displacement disc, it is chimeric with loam cake and housing, loam cake can be slided along chute on housing, and at the loam cake front end opening is set, when loam cake slid into the chute bottom, the USB joint can stretch out from openend.

Another purpose of the present utility model provides a kind of structure-improved of USB displacement disc, when it can make loam cake retreat the USB joint stretched out, do not increase the volume of displacement disc,, can not cause user's inconvenience because of the displacement disc that protrudes on the main frame when directly being inserted in when using on the computing machine.

For achieving the above object, the utility model provides a kind of structure-improved of USB displacement disc, and it comprises a housing, and its side is provided with at least one chute; A circuit arrangement, it is arranged in the housing, comprises a memory device in circuit arrangement, but storage data, and on circuit arrangement, be connected with a USB joint, it exposes outside this housing, can be plugged in the USB slot of computing machine, be used for the data transmission between circuit arrangement and the computing machine; And an over cap, it is installed in outside housing and the USB joint, can slide before and after chute, is provided with a rectangle hole at the over cap front end, and when over cap slid into the chute bottom, the USB joint can stretch out from the rectangle hole.Because over cap and housing link together, so over cap can not lose, and the volume of displacement disc can not increase along with opening over cap yet.

Compared with prior art; the structure improved beneficial effect of the utility model USB displacement disc is; it is installed in over cap on the housing; utilize a plurality of fixedly tenons that over cap is fixing in pickup groove and chute; avoiding over cap to slide arbitrarily, and over cap the place ahead is provided with a hole so that behind the over cap when sliding the USB joint extended.Because over cap of the present utility model is to be installed on the housing, allow the USB joint stretch out by the slip of over cap from the hole in over cap the place ahead, do not have the problem of losing over cap.No matter and whether the USB joint stretch out, can not increase the length of displacement disc, therefore directly be inserted in when using on the computing machine when the utility model, can not cause user's inconvenience because of the displacement disc that protrudes on the computing machine.

Below illustrate in detail by specific embodiment, make the purpose of this utility model, technology contents, characteristics and the effect reached is easier to understand.

Embodiment

The utility model provides a kind of structure-improved of USB displacement disc, exploded view as shown in Figure 3, comprise circuit arrangement 10, comprising a memory device, but storage data further can comprise an interface circuit, a circuit board and an integrated circuit, and is connected with USB joint 12 on circuit arrangement 10, can be plugged in the USB slot of computing machine, be used for the data transmission between circuit arrangement 10 and the computing machine; Be coated with rectangle housing 14 at circuit arrangement 10, it is combined by upper shell 142 and lower house 1 44, yet this housing 14 does not coat USB joint 12 together, stretch out for USB joint 12 but at housing 14 front ends an opening is set, the side at housing 14 is provided with at least one chute 147 in addition; Over cap 16; also combined by loam cake 162 and lower cover 164; it is installed in outside housing 14 and the USB joint 12; can slide along chute 147 front and back; be provided with rectangle hole 166 at over cap 16 front ends; when over cap 16 slid into chute 147 bottoms, USB joint 12 can be by stretching out in the rectangle hole 166.In addition, be provided with perforation 148 in housing 14 rear ends, threading is so that easy to carry thereon.

Structural representation of the present utility model such as Fig. 4 and shown in Figure 5, over cap 16 can slide front and back on housing 14, and when over cap 16 slided backwards on the bottom, USB joint 12 stretched out from rectangle hole 166.Detailed action mutual between this over cap 16 and the housing 14 please refer to Fig. 6 and Fig. 7, the utility model is a closed condition in Fig. 6, respectively be provided with the pickup groove 146 of a undaform in housing 14 both sides, and over cap 16 inwalls are respectively equipped with two fixedly tenon 168a and 1 68b, it can be salient point or raised line, the fixing tenon 168a of being by USB joint 12 1 sides, two other is fixing tenon 168b, as shown in the figure, when over cap 16 was closed, just in time at the place, hole of rectangle hole 166, fixedly tenon 168a was unsettled for USB joint 12, fixedly tenon 168b then is fastened in the pickup groove 146, avoids over cap 16 to slide arbitrarily; When needs are opened over cap 16; as shown in Figure 7; the application of force is with its past pusher on over cap 16; fixedly tenon 168b broke away from pickup groove 146 and entered in the chute 147 this moment; then slipping in the pickup groove 146 blocking by fixing tenon 168a fixes; simultaneously, USB joint 12 stretches out from the rectangle hole 166 of over cap 16 front openings, and over cap 16 front ends and housing 14 offset over cap 16 is moved after can't be again.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model.Therefore any identity property of doing according to feature described in the utility model and spirit changes or modifies, and all should be encompassed in the scope of patent protection of the present utility model.
