In the Chinese utility model patent " a kind of composite plate with many sandwich of layers structure " of CN201755923U, disclose one and have
The composite plate of many sandwich of layers structure, sandwich of layers is functional high-polymer foamed materials, is combined in one by modes such as bonding, snappings
Rise, meet the demand of many-sided performance.
Composite board, during assembling use, is needed to be fixed ON TRAINS by specific fastening structure, and pacifies
Region near at dress sheet material often is stressed the region of maximum, if installing fastening structure to be designed with defect, and can serious shadow
Ring the quality that composite board is overall, make sheet deformation or breakage.At present, also rarely having good fastening structure, this utility model exists
This side up is studied.
Utility model content
For deficiency of the prior art, this utility model provides the fastening structure in a kind of train on composite board,
Sheet material is made to have the strongest tolerance of impacts.
This utility model is achieved through the following technical solutions.
Fastening structure on composite board in a kind of train, this fastening structure includes mounting seat and is located in this mounting seat
Screw, described mounting seat is provided with the narrow contracting portion that may be stuck in installing hole, described narrow contracting portion to be respectively provided on two sides with first spacing
Sheet and the second banking stop.
When composite board of the prior art is installed, typically directly installed by fastener or screw, this simple peace
Dress mode can make the installation place fragile structure of sheet material, by the most damaged during big impact.Clamp device in this utility model,
By narrow contracting portion and the structure of banking stop, it is possible to play and well fasten left and right, after installation, the first banking stop and the second banking stop
Sheet material near installation region had certain coating function, it is possible to reduce this region sheet material subjected to stress, sheet deformation
Or it is damaged.
As preferably, the side of the second banking stop is located at by described screw, is provided with installing hole in mounting seat, sets in this installing hole
There is torsion hole, rotate by inserting to turn round in hole by electric drill head, can complete operation is installed.
As preferably, the side of described second banking stop is provided with screw mounting seat, and this screw mounting seat is provided with screw.
As preferably, described narrow contracting portion being arranged with boss, this boss is filled in composite board and can significantly increase
The intensity of strong installation region, enables sheet material to resist bigger impulsive force.
Compared with prior art, the fastening structure structure during this utility model has the advantages that this utility model
Simply, easy to use, the intensity of the sheet material of installation place can be strengthened, add the impact resistance of sheet material.
Accompanying drawing explanation
Fig. 1 is the front view of fastening structure.
Fig. 2 is the axonometric chart of fastening structure.
Fig. 3 is the top view of fastening structure.
Fig. 4 is the decomposing schematic representation of composite board.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, this utility model is further described.
Seeing Fig. 1 to Fig. 3, the fastening structure on composite board in a kind of train, this fastening structure includes mounting seat 5 and is located at
Screw 54 in this mounting seat 5, described mounting seat 5 is provided with the narrow contracting portion 53 that may be stuck in installing hole, described narrow contracting portion 53
It is respectively provided on two sides with the first banking stop 51 and the second banking stop 52.
In present embodiment, the side of the second banking stop 52 is located at by described screw 54, is provided with installing hole 511 in mounting seat 5,
This installing hole 511 is provided with torsion hole 512, facilitates electronic installation screw 54；The side of described second banking stop 52 is provided with screw peace
Dress seat 55, this screw mounting seat 55 is provided with screw 54.
Additionally, for the intensity improving sheet material further, described narrow contracting portion 53 is arranged with boss 4.
See Fig. 4, for a kind of composite board for train, including upper cover plate 1, lower cover 3, described upper cover plate 1 and lower cover
Being provided with sandwich foam layer 2 between plate 3, this composite board is provided with installing hole, and described installing hole includes be located on upper cover plate 1
One through hole 11, the second through hole 21 being located on sandwich foam layer 2, the third through-hole 31 be located on lower cover 3, described second through hole
Being provided with boss 4 in 41, described boss 4 is provided with fourth hole 41；Described first through hole 11, third through-hole 31, four-way
Hole 41 consistency from top to bottom forms installing hole, can be inserted into fastening structure and composite plate be fixed in this installing hole.
In present embodiment, described upper cover plate 1 is carbon fibre/glass composite bed, concrete, including two-layer carbon fibre layer and one layer
Fiberglass layer, the arrangement mode of the carbon fiber in carbon fibre layer is (0,90), the arrangement mode of the glass fibre in fiberglass layer be (45 ,-
