Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is a kind of overall structure diagram of specific embodiment provided by the present invention.
In a kind of specific embodiment provided by the present invention, the board fastening structure of machine box for server mainly includes setting
Main/standby board cards 1, step screwed pipe 2 and locking stud 3.
Wherein, the predetermined position on equipment plate card 1 offers through-hole, and step screwed pipe 2 is installed in the through hole, and
And there is internal screw thread, in general, the bottom stage of the step screwed pipe 2 is to abut plate 201, for being pressed on equipment plate card 1
On bottom surface, and the top of the step screwed pipe 2 is due to the influence of manufacturing tolerance and the location tolerance between equipment plate card 1, protrusion
Equipment plate card 1 surface programming distance.
Locking stud 3 with step screwed pipe 2 for being coupled, to simultaneously clamp on from the surface of equipment plate card 1 and bottom surface
Fixed equipment board 1.The locking stud 3 includes umbrella portion 301 and is connected to the bar portion 302 that 301 bottom surface of umbrella portion is fanned, wherein bar portion
302 with the screw-internal thread fit of step screwed pipe 2 for connecting, and umbrella portion 301 is used for the surface of compression apparatus board 1.
Importantly, offering annular groove 303 on the bottom surface in umbrella portion 301, which is mainly used for accommodating
The tube wall of step screwed pipe 2.In this way, when being matched by locking stud 3 with step screwed pipe 2 with fixed equipment board 1, it is right
In on step screwed pipe 2 due to tolerance factor protrusion 1 surface of equipment plate card part, can be by the annular groove 303 in umbrella portion 301
It is accommodated, guarantees the proper engagement of the internal screw thread on bar portion 302 and step screwed pipe 2, enable the bottom surface in umbrella portion 301 suitable
Benefit is pressed on the surface of equipment plate card 1, is then simultaneously clamped on from the bottom surface of equipment plate card 1 and surface, guarantees stability maintenance,
Eliminate manufacture, the fixed adverse effect of location tolerance accumulation bring board.
In a kind of preferred embodiment about locking stud 3, opened up on 301 bottom surface of umbrella portion of the locking stud 3
Annular groove 303, for guarantee completely accommodate 2 top of step screwed pipe protrude 1 surface of equipment plate card height, the annular
The depth of groove 303 need to be greater than the protrusion height.Certainly, the depth of annular groove 303 is exactly equal to the protrusion of step screwed pipe 2
Height is best.
In actual application, the depth of annular groove 303 is generally greater than the protrusion height of step screwed pipe 2,
In such cases, to improve the locking degree between locking stud 3 and step screwed pipe 2, the present embodiment is in annular groove 303
It has been laid with one layer of washer 4.The washer 4 has elasticity, is mainly used for abutting against with the tube wall top of step screwed pipe 2.In this way, working as
When the cooperation of locking stud 3 and step screwed pipe 2 is gradually deepened, the tube wall top of step screwed pipe 2 gradually gos deep into annular groove
303 inside, when the cooperation for locking stud 3 and step screwed pipe 2 reaches appropriate degree, the tube wall top of step screwed pipe 2
Packing washer 4 makes it generate elastic deformation, to keep certain pretightning force, improves between locking stud 3 and step screwed pipe 2
Cooperation compactness.
Based on same consideration, in the present embodiment, the outer diameter of step screwed pipe 2 may be slightly larger than to be opened up on equipment plate card 1
Through-hole, in this way, step screwed pipe 2 will can form interference fit with the through-hole on equipment plate card 1.So set, passing through locking screw
Column 3 is locked with step screwed pipe 2, and equipment plate card 1 can not only beat in a thickness direction, in the horizontal direction also without
Method bounce.Certainly, between the through-hole on step screwed pipe 2 and equipment plate card 1 can also be gap or transition fit, to a certain degree
Horizontal displacement can permit in certain application scenarios.
Furthermore, it is contemplated that when forming solid lock between locking stud 3 and step screwed pipe 2, the abutting of 2 bottom of step screwed pipe
Plate 201 and 301 bottom surface of umbrella portion for locking stud 3 will press with the bottom surface of equipment plate card 1 and surface respectively, to avoid being used for a long time
Fatigue failure, reduces the abrasion between face and face, and the present embodiment is all provided on the bottom surface on the surface and umbrella portion 301 that abut plate 201
Anti-abrasive coatings are set.It is of course also possible to which anti-abrasive coatings are arranged on the surface and bottom surface of equipment plate card 1 simultaneously.
As shown in Fig. 2, Fig. 2 is the structural schematic diagram of adjusting gasket in a kind of specific embodiment provided by the present invention.
Moreover, it is contemplated that locking stud 3 is generally standard component, processes annular in 301 bottom surface of umbrella portion of locking stud 3
Groove 303 is less convenient in technique, and production efficiency is lower, in view of this, bar portion 302 of the present embodiment in locking stud 3
A piece of adjusting gasket 5 is arranged on bottom end, which has certain thickness, can add the integral thickness for making umbrella portion 301.Together
When, annular groove 501 is offered on the bottom surface of adjusting gasket 5, the effect and the effect phase of aforementioned toroidal groove 303 of the annular groove 501
It together, is to protrude part for accommodating the tube wall of step screwed pipe 2.In this way, due to processing groove in smooth adjusting gasket 5
It is more convenient in technique, therefore be conducive to save cost.Meanwhile locking stud 3 on be arranged adjusting gasket 5 after, Ji Kewu
Annular groove 303 need to be opened up in 301 bottom surface of umbrella portion.
The present embodiment also provides a kind of machine box for server, main including cabinet and the board being arranged on cabinet fastening knot
Structure, wherein the particular content of the board fastening structure is identical as above-mentioned related content, and details are not described herein again.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
