Abstract
The utility model provides a kind of board card device reducing failure rate, belong to board technique for fixing field, the utility model is by fixed orifice shape and fixed leg structure on amendment board, a screw was used to fix by originally needing the fixing board of the screw of several or tens, this design can reduce because fixed bolt height differs the risk of board local pressure, can installation rate be accelerated simultaneously, increase work efficiency.
Description
Technical field
The utility model relates to board technique for fixing field, and specifically a kind of board card device reducing failure rate, to decrease the set-up time, accelerates installation rate.
Background technology
Along with the development of electronic information technology, the board of various function also occurs thereupon, absorbing all the useful ideas to install various board structure engineers in limited structure space inside, designing a lot of ways, but because structural member is processed with error, the stud height of fixing board card has certain deviation, can, because of stressed inconsistent between each point, board be caused to be out of shape, long-time unbalance stress after board is screwed structural member, the performance of board can be affected, and even board is damaged.The fixed hole position shape that present major part uses is circular, and the radius of fixed orifice depends on the radius of fixed screw, has several fixed orifice will use several screws when fixing board card.
Summary of the invention
The utility model will solve above technical matters, provides a kind of board card device reducing failure rate, to reduce because fixed bolt height differs the risk of board local pressure, improves dismounting speed simultaneously.
The utility model solves the technical scheme that its technical matters adopts:
A kind of board card device reducing failure rate, comprise board and base plate, board is arranged on base plate, the surface of base plate is provided with a fixed leg and is connected with its bottom, fixed leg upper end open also offers internal thread, and the surface of base plate is also provided with several reference column, and each reference column is identical with the height of aforementioned fixed leg, the upper end of each reference column is provided with T-shaped card cap and forms one with reference column, is connected together between board and base plate by fixed leg, reference column.
Preferably, board is provided with the positioning through hole corresponding with reference column, by this positioning through hole, board is connected between T-shaped card cap and reference column upper end; Board is also provided with a fixed via corresponding with fixed leg, by the screw through this fixed via, board is fixed on fixed leg.
Further, described positioning through hole is 8 word holes.
Further, described positioning through hole is provided with three, and the line between positioning through hole and fixed via forms a rectangle.
The utility model is that stud (is increased a part by the amendment shape (changing circle is two circles of reporting to the leadship after accomplishing a task mutually) of fixed hole position and the shape of fixed bolt, reel off raw silk from cocoons and make spill in original inside), after first board being snapped into above stud when mounted, after shifting precalculated position onto forward, fix with a screw, board has certain activity space on upper-lower position, reduce the stressed of this direction, board can not be out of shape because of stressed, a screw was used to fix by originally needing the fixing board of the screw of several or tens, decrease the set-up time, accelerate installation rate, improve work efficiency.
The beneficial aspects that the utility model brings:
By fixed orifice shape and fixed leg structure on amendment board, a screw was used to fix by originally needing the fixing board of the screw of several or tens, this design can reduce because fixed bolt height differs the risk of board local pressure, can installation rate be accelerated simultaneously, increase work efficiency.
Accompanying drawing explanation
The structural representation that accompanying drawing 1 is the reference column of the same side, fixed leg is connected with base plate.
Accompanying drawing 2 is vertical views that board is connected with base plate.
Accompanying drawing 3 is structural representations of board.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail below.
As shown in Figure 1, 2, the board card device of reduction failure rate of the present utility model, its structure comprises board 5 and base plate 2, board 5 arranges on a base plate 2, the surface of base plate 2 is provided with a fixed leg 1 and is connected with its bottom, fixed leg 1 upper end open also offers internal thread, and the surface of base plate 2 is also provided with three reference columns 3, each reference column 3 is identical with the height of aforementioned fixed leg 1, and the upper end of each reference column 3 is provided with T-shaped card cap 4 and forms one with reference column 3.The diameter of T-shaped card cap 4 is less than the diameter of reference column 3.
As shown in Figure 2,3, board 5 is provided with the positioning through hole 6 corresponding with reference column 4, described positioning through hole 6 is 8 word holes, is connected between T-shaped card cap 4 and reference column 3 upper end by this positioning through hole 6 by board 5; Board 5 is also provided with a fixed via 8 corresponding with fixed leg 1, by the screw 7 through this fixed via 8, board 5 is fixed on fixed leg 1.
Through actual verification, use because unbalance stress causes the probability of board faults to reduce after the utility model, the minimizing of fixed screw quantity is that the assembling speed of workman improves greatly, improves work task efficiency.
Its processing and fabricating of board card device of reduction failure rate of the present utility model is simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characteristic described in instructions, be the known technology of those skilled in the art.
