Larger vibration is produced in transport, but current mainboard neither one shock-damping structure so that mainboard withstands shocks and shaken
It is dynamic, reduce service life.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of any tune for the upper-lower position that can realize mainboard
Section, mainboard screw is integrated in the screw of upper-lower casing together with, reduce screw usage amount, and this structure can be effectively right
Mainboard carries out a protection, plays a part of damping, buffering, increases ability when shock resistance, resistance to compression.
The utility model is achieved through the following technical solutions：A kind of mainboard mounting structure of Switching Power Supply, including
The Switching Power Supply box of upper shell, lower house composition, is provided with connect base on the bottom surface of the lower house, is set in connect base
Connection screw thread, a screw run through is provided with the upper shell of face connect base, through screw, a piece screw rod, screw rod are set
Interlude be smooth section, the bottom of screw rod is thread segment, and its thread segment engages connection with the connection screw thread in connect base, four
One piece of mainboard to soar is installed, four Angle Positions on mainboard are provided with a pilot hole, four screw rods between root screw rod
It is each passed through pilot hole to screw in in connect base, more than one sealing shroud is provided with the screw rod.
As preferable technical scheme, the sealing shroud upper and lower side is provided with least two, mainboard be installed on four it is close
The centre of big envelope, and soared and be arranged between upper-lower casing by sealing shroud.
As preferable technical scheme, the section of sealing shroud is in " T " font, and it is internally provided with a pilot hole, assembling
The smooth section close fit of hole and screw rod connects.
As preferable technical scheme, more than one heat emission hole is offered on upper shell, its top outer end is provided with
One heat abstractor.
As preferable technical scheme, the heat abstractor is fan heat sink, to upper-lower casing inside during its work
Produce a negative pressure.
The beneficial effects of the utility model are：The utility model can realize any regulation of the upper-lower position of mainboard, will
Together with mainboard screw is integrated in the screw of upper-lower casing, screw usage amount is reduced, and this structure can be effectively to mainboard
A protection is carried out, plays a part of damping, buffering, increases ability when shock resistance, resistance to compression.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), except non-specifically chatting
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, the Switching Power Supply box formed including upper shell 3, lower house 1, is set on the bottom surface of the lower house 1
There is connect base 2, connection screw thread is set in connect base 2, one is provided with the upper shell 3 of face connect base 2 and is run through
Screw, a piece screw rod 9 is set through screw, the interlude of screw rod 9 is smooth section, and the bottom of screw rod 9 is thread segment, its thread segment
Connection is engaged with the connection screw thread in connect base 2, one piece of mainboard to soar 8 is installed between four screw rods 9, on mainboard 8
Four Angle Positions are provided with a pilot hole, and four screw rods 9 are each passed through pilot hole and screwed in in connect base 2, the spiral shell
More than one sealing shroud 7 is provided with bar 9.
In the present embodiment, the upper and lower side of sealing shroud 7 is provided with least two, and mainboard 8 is installed in four sealing shrouds 7
Between, and between being soared by sealing shroud 7 and being arranged at upper-lower casing, the section of sealing shroud 7 is in " T " font, and it is internally provided with one
The smooth section close fit connection of individual pilot hole, pilot hole and screw rod.It can go to realize by the sealing shroud of sufficient amount to mainboard
Upper-lower position it is spacing, optional position can be installed on, and closer to upper shell, heat dispersion is better, due to soaring
Setting, the installation site of mainboard is no longer limited to, and mainboard is not affected by external vibration, effectively increases service life, then
Person, if between upper shell and lower house and mainboard by four screw rods i.e. can be achieved, eliminate the use of a large amount of screws.
Wherein, more than one heat emission hole 6 is offered on upper shell, its top outer end is provided with a heat abstractor,
Heat abstractor 4 is fan heat sink, produces a negative pressure to upper-lower casing inside during its work.When temperature is too high, pass through
Open external radiating device, you can quick heat radiating is realized, produces a negative pressure, is suctioned out the heat of inside by heat emission hole, by
It is near apart from heat emission hole in mainboard, therefore there is extraordinary heat dispersion.The power supply of heat abstractor can be used built in one
Battery or using attaching plug connection external power receptacle power supply.
The beneficial effects of the utility model are：The utility model can realize any regulation of the upper-lower position of mainboard, will
Together with mainboard screw is integrated in the screw of upper-lower casing, screw usage amount is reduced, and this structure can be effectively to mainboard
A protection is carried out, plays a part of damping, buffering, increases ability when shock resistance, resistance to compression.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work, should all cover within the scope of protection of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
