Abstract

The utility model relates to an installation positioning device of an extended board of a computer, which comprises a fixed board and a bracket installed on a case, wherein, a central part of the fixed board is equipped with a long opening, one end of the fixed board is equipped with an invagination guide slot, while the other end of that is provided with a block button. Two ends of the bracket are respectively provided with block buttons and the invagination guide slot, and external sides of the block button and the invagination guide slot on the bracket are respectively provided with fixed holes of the installation extended board; besides, a central part of the bracket is provided with a spring plate, which is inserted in the long opening of the fixed board; meanwhile, the block button on the bracket is locked with the guide slot on the fixed board, and the guide slot on the bracket is mutually locked with the block button on the fixed board. The utility model is able to make the surface appearance of a rear panel of the case become flat with pits, and assembles and disassembles the extended board with relatively convenience and simplification, thus reducing production cost.

Description

The mounting and positioning device of the expansion board clamping of computer

[technical field]

The utility model relates to a kind of mounting and positioning device of expansion board clamping of computer.

[background technology]

In computer system, expansion board clamping is the parts that we use always, we realize all multi-functional of computer system by these expansion board clampings, two kinds of mounting meanss that at present the computer expansion board clamping is most below adopting: the first is installed in expansion board clamping in the standard draw-in groove on the cabinet, on the outstanding card of expansion board clamping one end, use screw and cabinet to fix simultaneously, this fixed form is suitable for the situation that integrated circuit board vertically inserts the mainboard expansion slot, though this fixing mode is simple, but this fixing mode needs the rear panel of cabinet will have the outstanding card that a depression is convenient to expansion board clamping to fix, and will make the outward appearance of rear panel more ugly like this; The another kind of fixed form of expansion board clamping is to open screw hole at the clear position of expansion board clamping, relevant position on mainboard adds double-screw bolt simultaneously, with expansion board clamping by screw retention on the double-screw bolt of mainboard, this fixed form is suitable for the situation that expansion board clamping is placed in parallel in the mainboard top, but this fixed form assembly and disassembly inconvenience, especially narrower and small for chassis space, more can increase the degree of difficulty of assembly and disassembly when arrangement of parts is very compact, and this fixed form in the component processing operation fixedly the quality of fit of the Kong Weiyu double-screw bolt of usefulness require height, if quality of fit may not get into trouble in follow-up installation exercise the higher position, therefore such fixed form causes the raising of production cost.

[utility model content]

The purpose of this utility model is to provide a kind of mounting and positioning device of expansion board clamping of computer, can make the smooth not depression of rear panel appearance of cabinet, simultaneously less demanding for the quality of fit of component processing operation, make the assembly and disassembly of expansion board clamping more simple and convenient, can reduce production costs.

In order to achieve the above object, the utility model provides a kind of mounting and positioning device of expansion board clamping of computer, comprises that one is installed in a fixed head and the support on the cabinet, it is characterized in that:

This fixed head middle part is provided with a microscler perforate, one end of fixed head is provided with a recessed gathering sill, the other end is provided with a buckle, corresponding buckle and the recessed gathering sill of being respectively equipped with in these support two ends, the buckle on this support and the outside of gathering sill are respectively equipped with the fixed orifice that expansion board clamping is installed, this mid-stent is provided with a shell fragment, this shell fragment inserts the microscler perforate of this fixed head, the gathering sill of establishing on buckle on this support and this fixed head is interlocked, and the buckle of establishing on the gathering sill on this support and this fixed head fastens mutually.

The mounting and positioning device of the expansion board clamping of computer of the present utility model, can make the smooth not depression of rear panel appearance of cabinet, simultaneously less demanding for the quality of fit of component processing operation, make the assembly and disassembly of expansion board clamping more simple and convenient, can reduce production costs.

[description of drawings]

Fig. 2 is the STRUCTURE DECOMPOSITION synoptic diagram of preferred embodiment of the present utility model.

[embodiment]

With reference to Fig. 1,2, the mounting and positioning device of the expansion board clamping of a kind of computer of the present utility model, comprise that one is installed in a fixed head 2 and the support 5 on the cabinet rear panel 1, these fixed head 2 middle parts are provided with a microscler perforate 3, one end of fixed head 2 is provided with a recessed gathering sill 21, the other end is provided with a buckle 22, corresponding buckle 51 and the recessed gathering sill 52 of being respectively equipped with in these support 5 two ends, the buckle 51 on this support 5 and the outside of gathering sill 52 are respectively equipped with the fixed orifice 4 that expansion board clamping is installed, these support 5 middle parts are provided with a shell fragment 53, the microscler perforate 3 that this shell fragment 3 inserts this fixed head 2, the gathering sill of establishing on buckle 51 on this support 5 and this fixed head 2 21 is interlocked, and the buckle of establishing on the gathering sill 52 on this support 5 and this fixed head 2 22 fastens mutually.

After when assembling is fixed on expansion board clamping on the fixed orifice 4 of support 5, along the direction of arrow among Fig. 2 21 cooperations of 2 gathering sills of the fixed head on buckle on the support 5 51 and the cabinet rear panel 1 are slided into the position that is interlocked, buckle 22 on the fixed head 2 and the gathering sill 52 on the support 5 are interlocked simultaneously, this moment, the shell fragment 53 at these support 5 middle parts promptly sprang in the microscler perforate 3 of this fixed head 2, several degree of freedom of support 5 all are positioned like this, avoid occurring sliding, whole assembling work has just been finished.If support 5 is removed, as long as push this shell fragment 3 and push away to the direction opposite with arrow among Fig. 2 with hand, buckle 51,22 promptly breaks away from gathering sill 21,52, support 5 can be removed from fixed head 2, and assembly and disassembly is all very convenient.
