Support includes the anti-bias face in 2 faces and anti-bias convex tendon, and the anti-bias convex tendon is arranged on the left side in anti-bias face, therefore the prefastened support is
Deflection enters in roof hole counterclockwise, during fastening, prefastened support can stress to right rotation, when reaching center, prefastened support
Meeting stress is maximum, no longer turns right, now anti-bias convex tendon is close to the hole wall in roof hole, that is, realizes anti-bias function.
Embodiment 2：
Car antenna anti-deflection fixing device in the present embodiment, as shown in Figure 1.It is clamped including prefastened support, pretension
Frame includes the anti-bias face in 4 faces and anti-bias convex tendon, and the anti-bias convex tendon is arranged on the left side in anti-bias face, parallel anti-bias convex in two anti-bias faces
Muscle is one group of anti-bias component, and the anti-bias convex tendon Central Symmetry in anti-bias component（180 ° of rotation is symmetrical）, anti-bias component includes anti-
Inclined convex tendon is the first anti-bias component of rectangle and anti-bias convex tendon is the trapeziform second anti-bias component, irregular quadrilateral
Anti-bias convex tendon specifically include be arranged on anti-bias face base, with anti-bias face support edge connected vertically, with anti-bias face tilt
The buffer edge of connection and connection support edge and the positioning side of buffer edge；Anti-bias face where first anti-bias component with second anti-bias group
Anti-bias face where part is vertical.
In use, because anti-bias convex tendon is arranged on the left side in anti-bias face, thus the prefastened support for deflect counterclockwise into
Enter in roof hole, during fastening, prefastened support can stress to right rotation, when reaching center, prefastened support can stress it is maximum, no
Turn right again, now anti-bias convex tendon is close to the hole wall in roof hole, that is, realizes anti-bias function.
Embodiment 3：
Based on the 1st, the 2nd embodiment, the positioning side is parallel with base, the anti-bias convex tendon and the folder in anti-bias face where it
Angle is 3 ° -25 °.
Embodiment 4：
As Figure 1-3, based on above-described embodiment, the car antenna anti-deflection fixing device in the present embodiment also includes shark
Fin antenna casing, mounting seat, fixed claw and fastening bolt, the shark fins antenna casing is connected with mounting seat, described
Fastening bolt is sequentially connected fixed claw, prefastened support and mounting seat.
During product turnout, shark fins antenna casing, mounting seat, prefastened support, fixed claw and fastening bolt are connected as
One entirety, day wire wrapping only need entire package, are also not in scratch antenna and produce defective products；, will be prefastened during installation
Support, fixed claw and fastening bolt pass through roof hole, and because anti-bias convex tendon is present, prefastened support fastens towards prefastened support
Opposite direction deflection enters roof hole, and as fastening bolt screws the slowly correcting of prefastened support, fixed claw is also strutted and caught therewith
Roof inner surface, so as to complete the installation of shark fins antenna casing, the now axis of shark fins antenna and the axis of automobile
Unanimously.
Embodiment 5：
As Figure 1-3, based on the 4th embodiment, the prefastened support in the present embodiment also includes being used for through roof hole
When ejecting card pick up apical pore pre-fix buckle；Fixed claw includes expanding outwardly along prefastened support with the locking of fastening bolt
Adjutage, the end setting pressing down section rolled over of the adjutage, prefastened support be provided with for adjutage glide slide rail, institute
State slide rail and anti-bias face is arranged at intervals, the quantity of the slide rail is 4；The mounting seat is provided with what is be connected with prefastened support
Insertion section, the insertion section are provided with the brace rod corresponding with the position of slide rail, correspondingly set on insertion section and prefastened support
Anti-rotational structure has been put, including the anti-rotational muscle being arranged on insertion section and the anti-rotational groove being arranged on prefastened support, or
Including the anti-rotational muscle being arranged on prefastened support and the anti-rotational groove being arranged on insertion section.
In the present embodiment, fixed claw is made of the preferable metal material of toughness, and prefastened support, which uses, has certain bullet
Property plastic parts be made, mounting seat is made of the stronger metal material of hardness.During product turnout, pass through mounting seat and shark
Fin antenna is directly fixedly connected, and fastening bolt passes through the insertion section of fixed claw, prefastened support and mounting seat, for will be by tight
The projection that fixing bolt, fixed claw, prefastened support and insertion section form passes through roof hole, and it is firm to screw in stroke in fastening bolt
Fixed claw, prefastened support and insertion section can be fixed by reaching well, and the expansion scope of fixed claw can pack whole when being less than roof hole
Body shipment.Overall shipment after the antenna fixing device of this structure, antenna and fixing device assembling, has saved the bag of a part
Dress, and defective products will not be produced because fastener scratches top antenna, improve the satisfaction of client.When mounted, by antenna
It is overall to take out, above-mentioned ledge is passed through into Automobile apical pore, now pre-fixing on prefastened support snaps through roof hole
I.e. outwards ejection afterwards, blocks roof inner surface, reaches and pre-fix effect；Because anti-bias convex tendon is present, prefastened support is towards pretension
The opposite direction deflection of clamped frame fastening enters roof hole, and as fastening bolt screws the slowly correcting of prefastened support, fixed claw is then
Glided along the slide rail on prefastened support and to mounting seat under the supporting role of brace rod, between mounting seat and fixed claw
For roof inner surface, when bolt is screwed to the end, i.e., pressing down section is in the outermost expanded outwardly, and now the pressure of pressing down section is led to
Cross roof and be transferred to support block, preferably protect roof and mounting seat, so as to complete the installation of shark fins antenna casing.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned implementation
Mode, can also be on the premise of present inventive concept not be departed from those of ordinary skill in the art's possessed knowledge
Various changes can be made.
