Description
Technical field
The utility model relates to a kind of anti-escape device of computer interface card.
Background technology
In the main frame of a computer, the interface card is the basic functions element, and it is along with different functional requirements, and has the interface card that number does not wait.And the interface card of difference in functionality, different progression is used in the computer for convenience, therefore, but interface card and combining of main frame are adopted the inserting mode of elasticity combination, normally form the conduction terminal pin on one side of interface card, and establish many rows' slots on the main frame, insert with the conduction terminal pin of interface card can finish simply in the slot of main frame and settle or random replacing.Above-mentioned slot generally is to adopt the mode that inserts and puts the interface card about reed to fix, this interface card should be clamped securely with the performance function in theory, but learn by practical operation, often because of the bad of reed manufacturing or change the formed elastic fatigue of interface card for a long time, make the interface card inserted and put the back often generation can't deeply clamp or can plant deeply but the phenomenon that can't clamp, the consequence of this situation is that the interface card can't mat and close the combining and have the function flaws such as fault, short circuit or signal instability to shelter of slot.In view of this, a cross bar 8 is placed in the upper edge of interface card 7, the two ends of bar are fixed at (as shown in Figure 7) on the main machine frame 6, by this each interface card 7 being forced to press down makes it contact completely with slot, and as if can promote the effect of connecting airtight between interface card and the slot on this practice surface, but learn by the operation of practice, the interface card of fixing cross bar compacting multi-disc, often an interface card is desired to change or during maintenance therein, whole cross bar must be removed, and the very inconvenience that seems, moreover cross bar might be because of the problem in material or the making, and the situation that bends, this also may cause cross bar two ends spiral shell solid, but the middle phenomenon that bends up, and this possibly can't effectively being pressed down with slot of the interface cacaine in this knee combines.
Summary of the invention
Technical problem to be solved in the utility model is, above-mentioned deficiency at prior art, and provide a kind of interface card of can suppressing really to prevent its up escape, and reach the anti-escape device that contacts the computer interface card of purpose with slot fully, this device can impose really effectively compacting at each other interface card, with the independent operation of convenient interface card out of the ordinary.
Above-mentioned technical matters of the present utility model is realized by following technical scheme.
A kind of anti-escape device of computer interface card is characterized in that: comprise a casket seat, link block and depression bar, wherein:
The casket seat, a plurality of locks road is offered in its bottom, and the leading edge in lock road forms a clamping flange, and the trailing edge in lock road offers a draw-in groove, and the trailing flank of groove forms a card projection; The rear, top of casket seat forms high rising, and the nearly apical margin that this height rises is established a plurality of grabs that protract; And the casket seat forms a caulking groove in the two sides, back, and this caulking groove of mat and aforesaid grab respectively with main machine frame on set coupler body and perforate fasten, and this casket seat is installed on the main machine frame;
Depression bar, an end inner face is convexly equipped with the axle center that a brace has perforate, and the outer root edge of the other end forms the parallel raised line of multiple tracks;
Link block is as it can be installed in the connector of casket seat, have one below be the groove of vertical perforation body, and the position buckles as a plurality of fixings that combine with the casket seat at end face, other establishes the perforation of a lateral direction penetrating;
The axle center of above-mentioned depression bar wears a torque spring, and sell solid element with this axle center utilization its pin is closed in perforation place of link block, and this depression bar is installed in the groove of link block, and this combination is detained buckle on clamping flange, draw-in groove and the card projection of casket seat with each fixing of end face of link block again.
Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:
Depression bar is the state that often presses down after being incorporated into link block.
Interface card apical margin is in the slit that is pressed between two raised lines of depression bar root edge.
For the device of realizing these purposes is a kind of up device of escape of computer interface card that prevents, it has comprised a depression bar, it is the apical margin top that is placed in after the interface card is planted, the one end articulates a torque spring, and make its other end often keep being pressed on down the state of interface card apical margin, to be mat be hubbed in the groove of below of a link block in conjunction with an end of torque spring this depression bar, one of them of the Pai Zha road that is embedded in casket seat bottom buckled in these a plurality of fixings in link block top of mat again, and the casket seat is then on the caulking groove and framework that grab is incorporated into main frame of its rear side of mat.As above-mentioned device, depression bar is subjected to the effect of torque spring, make its normal state that presses down of protecting in the groove of link block, and produce a strength that presses down, can it is inserted in the slot fully the compacting downwards of interface card by this, and the position that the root edge of this depression bar and interface card press also can form many spaced apart raised lines, the thickness with the interface card places between this two raised line and compacting by this, thereby prevent the sliding phenomenon under pressure, and can guarantee firm compacting.Moreover this depression bar still must upwards rise a maximum height limit in the groove of link block, must carry out the adjustment of depression bar position slightly so that interface cacaine height tolerance to be provided.
Learn by above-mentioned structure, install a depression bar separately as long as plug the top of position in the interface card, can reach the purpose of compacting interface card, and if when desiring more to renew the interface card, the link block that also only needs simply will to connect depression bar is removed on the casket seat and is got final product, be not required to be single interface card and removed all depression bars, more both do not known that the person is convenient.Certainly, the casket seat also can be pulled down from main machine frame easily, and with convenient operation when a plurality of interface card desires are changed, therefore, the utility model is possessed splendid operating flexibility.
Advantage of the present utility model is:
When 1, more renewing the interface card, the link block that only needs simply will to connect depression bar is removed on the casket seat and got final product, and has not been required to be single interface card and removes all depression bars, and is easy to use.
2, the casket seat can be pulled down from main machine frame easily, with convenient operation when a plurality of interface card desires are changed, has splendid operating flexibility.
For structure of the present utility model, feature and effect thereof are had further understanding, enumerate specific embodiment now and be described with reference to the accompanying drawings as follows:
