Description

Host computer cover plate dust guard

The utility model relates to a kind of host computer cover plate dust guard.

General vertical type host computer commonly used, its panel position all are not equiped with any device that dust falls into that supplies to prevent, yet are provided with for the jack that inserts disk or magnetic sheet at position, vertical type Computer master panel upper end, and various operation push-button.Above-mentioned jack and button are all retained at panel easily tiny space, interval, makes host computer in long use, the dust foreign material can be arranged by the situation that above-mentioned space falls into, and influences the host computer normal running, functions of use and life-span.This is the constructional defective of vertical type host computer commonly used.

The purpose of this utility model is that a kind of unlatching host computer cover plate dust guard easily is provided on the basis that overcomes above-mentioned prior art defective, and this kind device moves steady, safe and reliable, can prolong the life-span of main frame.

The purpose of this utility model is achieved in that a kind of host computer cover plate dust guard, comprises a host panel supporting with it and a cover plate, and respectively there is the caulking groove of an invaginated type host panel both sides, and the bending end of cover plate both sides can stretch into and be contained in this caulking groove; The inwall position of cover plate left side bending end is provided with one and can produces the oil pressure reduction gearing that damping slows down, and a tooth bar is established at the position, limit, left side that the cover plate bending end is contained in the panel caulking groove relatively, and the oil pressure reduction gearing is sticked on the tooth bar; The right cylinder that several have center pit is established at the back, the outside of this tooth bar; A fixed frame is respectively established in the panel both sides, and this fixed frame support body is provided with the inserting column that a plurality of outside stretching, extensions are vertical, and its right cylinder with center pit that can insert the tooth bar back is interior with the guiding location; Panel bending end madial wall edge slightly below snapping one be banded spring leaf in an end, this spring leaf other end be wound on bottom, panel left side fixing one turn on; The side position of the inserting column of fixed frame forms a buckle in addition, can live affixed one with the base fastener of tooth bar body.

But owing to increased the cover plate dust guard of smooth sliding, after the button on pushing cover plate, cover plate is slowly hung downwards, operating process is very convenient, and can prevent effectively that the dust foreign matter from entering host computer inside, prolongs the main frame life-span.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:

Fig. 1 is stereoscopic figure of the present utility model;

Fig. 2 is a structure decomposing schematic representation of the present utility model;

Fig. 3 A for Fig. 2 along A-A to buckleing of cover plate dust guard hold the element cut-open view;

Fig. 3 B is the stereographic map that buckleing of cover plate dust guard shown in Figure 2 held component construction;

Fig. 4 A and Fig. 4 B are the sliding position synoptic diagram of cover plate of the present utility model;

Fig. 5 A and Fig. 5 B and Fig. 5 C are the user mode synoptic diagram of cover plate dust guard of the present utility model.

Fig. 1 is for seeing stereographic map outside the utility model, embeds the cover plate 101 that can slide up and down as can be seen from Figure in the both sides of Computer master panel 100, comes shield panel 100 to have the position of hole by cover plate 101, prevents that dust from falling in the main frame.There is an outstanding body 102 at the position, the upper left corner of this cover plate 101, establish the button 103 of a square shape on it, when operator's finger is depressed this button 103, cover plate 101 is slowly hung downwards, make panel 100 tops expose magnetic sheet jack and each operation push-button that cover plate 101 is covered, can insert magnetic sheet and operation for the operator.

Fig. 2 is a structure decomposing schematic representation of the present utility model, respectively form the caulking groove 104 of an invaginated type as can be seen from Figure in Computer master panel 100 both sides, stretch into ccontaining in these cover plate 101 both sides bending end 101a with an energy shield panel 100 part positions, the inwall position of this cover plate left side bending end 101a is established one and can be produced the oil pressure reduction gearing 105 that damping slows down velocity of rotation, be positioned at this bending end 101a madial wall edge slightly the below then snapping one be banded spring leaf 106 in an end, and a tooth bar 107 is established at the position, limit, left side that the bending end 101a of cover plate 101 is contained in panel 100 caulking grooves 104 relatively, several right cylinder 107a with center pit are established at the back, the outside of this tooth bar, the oil pressure reduction gearing 105 of above-mentioned cover plate 101 sides installing is sticked on the tooth bar 107, be wound on fixing one the turning on 112 in bottom, a panel 100 left side and be banded spring leaf 106 other ends, the strength that these spring leaf 106 coiling homings are put can be pulled to cover plate 101 downwards panel 100 bottom positions, and the set right cylinder 107a with center pit in back, the tooth bar outside can be for outwards stretching the inserting column 108a that is vertical on a fixed frame 108 support bodys, insert thus and guided the location, and the side position of the inserting column of fixed frame 108 forms buckle 109 in addition, but fastener is on the base of tooth bar 107 bodies, give fixed frame 108 affixed being integral, this fixed frame 108 can guarantee to be contained in the cover plate 101 mild slippages in the caulking groove 104.

Fig. 3 A for Fig. 2 along A-A to the cover plate dust guard buckle the cut-open view of holding element, Fig. 3 B is the stereographic map that buckleing of cover plate dust guard shown in Figure 2 held component construction, can find out from above-mentioned two figure, but the position, the back side of the button 103 on the cover plate 101 is connected elasticity bending to be on the pressing plate 110 of plain film shape, one end of this pressing plate 110 is with the fastener body 110a of screw interlocking one bending, wherein the ora terminalis position of fastener 110a forms the fastener 110b of invaginated type, it can be detained to be held in and be positioned on the formed one prominent body 111 of position, tooth bar 107 upper end, so upwards be pulled up to the Computer master panel upper end position and the power that is subjected to spring leaf 106 downward pullings when drawing when cover plate 101, shown in Fig. 4 A and Fig. 4 B, can hold strength because of the fastener 110b of fastener body 110a button be held in the button that the prominent body 111 of tooth bar 107 produced, make cover plate 101 be fixed on the panel top position, can not hang downwards.And as Fig. 5 A, shown in Fig. 5 B and Fig. 5 C, when operator's finger is depressed button 103, then pressing plate 110 bends distortion immediately, the fastener 110b of fastener body 110a breaks away from the button of prominent body 111 and holds, cover plate 101 just was subjected to the strength of spring leaf 106 traction pulling downwards and hung and move down this moment, and by means of the damping oil pressure decelerating effect of oil pressure reduction gearing 105 on tooth bar 107, cover plate 101 is slided with mild even velocity to be fallen, between cover plate and panel, can not produce the stress of any mutual collision therebetween, and operating process is very convenient, and can guarantee to prevent that the dust foreign matter from entering host computer inside.
