Background technique

In the modern age of advanced information, many people use computers to record data. A portable memory device called a thumb drive or a flash drive is widely loved by people because it can easily memorize and carry computer data.

The traditional portable memory device includes a circuit board inside. In order to cooperate with the USB interface of the computer, a USB metal connector body must be made of metal, and then the upper shell and the lower shell are designed outside the USB metal connector body. After wrapping the two upper shells and the lower shell on part of the circuit board and the USB metal connector, the upper shell and the lower shell are combined in a high-frequency manner. In the traditional structure, when the manufacturer intends to carry out the high-frequency bonding process of the upper shell and the lower shell, there is a certain degree of defective product rate, which will cause waste of processing raw materials and waste man-hours. Moreover, the high-frequency bonding process cannot simplify the processing procedure. , and the appearance of a few finished products after lamination is not beautiful.

Contents of the invention

The purpose of the utility model is to provide a portable memory device with a plastic molded telescopic structure which improves the traditional two-piece housing into a single-piece type.

For reaching above-mentioned purpose, the concrete content of the present utility model is:

A portable memory device with a plastic molded telescopic structure, comprising:

An outer shell unit is elongated and hollow, with a space inside, an opening at one end, a hollowed-out part on the top surface, first grooves and second grooves correspondingly arranged on both sides of the hollowed-out part;

An inner sliding unit, which is accommodated in the space of the outer shell unit and can slide inside and outside, one end is a USB plug-in terminal, and an elastic pressing body is floating on the top, and a shrapnel is provided on the side of the pressing body. Can be displaced between the first groove or the second groove;

A closed unit, the plug is set at the spatial end of the outer housing unit.

Wherein the outer casing unit, the inner sliding unit and the closing unit are each formed as a whole made of plastic.

Wherein the inner sliding unit is provided with circuit board components.

Wherein the pressing body is floated on the inner sliding unit by means of a connecting portion, so that the bottom of the pressing body is hollow and slightly elastic.

Wherein the closed unit includes a plug body, a top plate is arranged on the top of the plug body, another side plate is arranged on the rear outside of the plug body, an extension body is arranged outside the side plate, a perforation is arranged on the extension body, and a Guide slots and card slots.

Wherein the space of the outer shell unit is provided with a clamping block, and the position of the clamping block corresponds to the guide groove and the clamping groove.

Wherein the bottom of the space is provided with slide rails.

The utility model has the effect of the portable memory device with a plastic molded telescopic structure. When the manufacturer manufactures the utility model, the high-frequency pressing process can be avoided, and the manufacturing process can be effectively simplified to reduce the rate of defective products, thereby reducing costs and increasing production. and lower prices.

Detailed ways

Below with regard to the structural composition and the effect that the utility model has the portable memory device of plastic molded telescopic structure and can produce, cooperate with accompanying drawing to describe in detail as follows with preferred embodiment:

Please refer to Figure 1 and Figure 2, the utility model has a portable memory device with a plastic molded telescopic structure, including:

An outer shell unit 1 is slightly elongated and hollow, and is made of plastic integral molding. There is a space 11 inside, an opening 12 is formed at one end, and a hollow part 13 is formed on the top surface. First concave parts are provided on both sides of the hollow part 13. The groove 14 and the second groove 15 are provided with a block 16 at an appropriate place in the space 11, and a slide rail 17 is provided at the bottom of the space 11;

An inner sliding unit 2, which is made of plastic integral molding, can be accommodated in the space 11 of the outer shell unit 1 and slide inside and outside. There are commercially available components such as circuit boards inside, and one end is a USB plug-in terminal 21. There is a pressing body 22 floating on the top at an appropriate place, and the pressing body 22 is floated on the inner sliding unit 2 by the connecting part 221, forming the bottom of the pressing body 22 is hollow, and has a slightly elastic effect, the pressing body 22 The side is correspondingly provided with shrapnel 23;

A closed unit 3, made of plastic integral molding, can be plugged at the end of the space 11 of the outer shell unit 1; the structure includes a plug body 31, a top plate 34 is provided on the top of the plug body 31, and a side plate 32 is arranged on the plug body 31 rear outer side, the side plate 32 is provided with an extension body 33, the extension body 33 is provided with a perforation 331, and the bottom of the plug body 31 is provided with a guide groove 35 and a catch groove 36, the guide groove 35 and the draw groove 36 are connected with the block 16 corresponds to the setting.

From the above, first put the inner sliding unit 2 into the space 11 of the outer shell unit 1, and because of the setting of the shrapnel 23, it is necessary to slightly press down the pressing body 22 before it can penetrate; put the inner sliding unit 2 into After the housing unit 1 is put in, the closing unit 3 is combined at last, and the block 16 can be combined in the slot 36 by the guide groove 35, so that the plug body 31 forming the closing unit 3 is sealed at the end of the space 11, and the top plate 34 is sealed. Cover the appropriate place in the hollow part 13 .

When you want to make the inner sliding unit 2 protrude outward, you need to press down the pressing body 22 slightly first, so that the shrapnel 23 can be lowered to get out of the first groove 14, then move the inner sliding unit 2 outward and stretch out, and finally The shrapnel 23 enters the second groove 15 to complete the extension and positioning functions, as shown in FIG. 3 .

When the inner sliding unit 2 is to be retracted again, the pressing body 22 is first slightly pressed so that the shrapnel 23 lowers its height and escapes from the second groove 15, and then the inner sliding unit 2 is moved to retract inwardly, waiting for the shrapnel 23 Entering the first groove 14, that is, the retraction and positioning are completed, and the state of FIG. 1 is returned.

The aforesaid opening 12 is properly provided with a partial covering around it, which can prevent the inner sliding unit 2 from falling out.

Although the utility model is described by the foregoing embodiments, its form and details can still be changed without departing from the spirit of the utility model. The foregoing is the most reasonable use method of the utility model, which is only one of the ways in which the utility model can be specifically implemented, but is not limited thereto.
