Description

Tool expands the fixing device of using function

Technical field

The invention provides the fixing device that a kind of tool expands using function, espespecially can for the fixing device of stacking shape sheet material assembling, location, worn for lock member activity by base interior containing space, and utilize end-to-end joint part set by lock member opposite side, outside default extending element can be coordinated, reach the object setting firmly stacking shape sheet material.

Background technique

General sheet material (plate is to plate), in time assembling, engage, is utilize the set screw with knob, the collar and screw to give interlocking, can apply to machine tool or other plates used the sheet material that plate connects; But, the plurality of machine tool needs to use sheet material to carry out interlocking place, sheet material Moveable assembled, interlocking, dismounting mode can be utilized, when power plant occur when machine or fault, damage, or when speed regulating device carries out change, the adjustment of speed, sheet material is unloaded divided by the maintenance carrying out being correlated with, adjustment operation, and sheet material is locked by multiple set screw, so easily cause the coming off of set screw in unloading process, lose, then cannot lock back sheet material original position again again, and inconvenience and the trouble of operation are assembled, disassembled in impact.

Moreover, along with constantly bringing forth new ideas of computer technology, progressive, computer or each electron-like, the aspect of electric product application is more extensive, using function continuous enlargement, increase, at computer or electronics, in electric product, in order to process various running, calculate, perform, the wire configuration of the functions such as analysis, central processing unit (CPU), wafer and various electronic components etc., also must appropriateness expand, increase, therefore wire configuration is configured, central processing unit (CPU), the circuit board of wafer and various electronic components etc., also the area and scope that increase and use can be expanded along with the application function of computer, but, in the inside limited available space situation of computer or electronics, electric product, control computer or electronics, circuit board that electric product starts running, also cannot enlarged-area scope, and industry is in order to solve the problem of circuit board application, namely by technology that circuit board is assembled plate mode with stacking shape plate, expand the application areal extent of circuit board, palette, to the circuit board application model of plate, uses in reality, when implementing, still there is a little trouble and puzzlement, as:

(1) plate is to the overlapping waded circuit board of plate, by multiple screw and the mutual interlocking mode of nut, locate stacking shape circuit board, but because the volume of screw and nut is little, not easily operable lock splitting or integrating solution, and during in circuit board assembling or for disassembling, keeping in repair, most nut and screw must be disassembled, quite consuming time, take a lot of work.

(2) although circuit board adopts the stacking mode of plate to plate to assemble, but during for increasing assembling circuit board again, namely cannot expand, usage space must also continue the electric connection circuit used in addition, cause the inconvenience of circuit board in design, application, the application area expanding circuit board can not be continued.

Be with, how to solve fixing device that current plate applies plate after assembling, namely problem and the puzzlement of application area cannot be expanded again, and the volume being limited to screw and nut in time assembling, disassemble is little, not easy to operate, control, impact assembling, disassemble disappearance and inconvenience that operation has some setbacks, be the place, direction that the relevant manufactures being engaged in the industry institute desires most ardently research improvement.
