For double insurance.
Continue with the specific installation and removal for illustrating attachment device.
For example, the disassembly process of attachment device are as follows:
(1) the big magnet of magnetic tool attracts the magnetic block in magnetic part close to attachment device outer surface, and elastic component resets
The big magnet of force ratio it is small to the active force of magnetic block, attachment device safe block button release.
(2) big magnet attraction effect under can be firm attachment device is sucked, separate it with cabinet.
(3) after attachment device is separated with cabinet, big magnet is tangentially removed from plane where attachment device, buckles ontology in bullet
Property part under the action of realize reset.It should be noted that the big magnet only needs greater than elastic component the attraction of magnetic block
Active force, and guarantee not fall after attachment device is detached from cabinet.
For example, the installation process of attachment device are as follows:
(1) when attachment device fitting cabinet, buckle ontology is slided along the guiding surface of the pedestal of snap seats, oblique by being oriented to
Ontology is buckled behind the highest point in face under the action of the elastic member to buckle on pedestal, so that buckle ontology is locked in guiding surface, connects
The positioning column of device is positioned on cabinet.
(2) snap seats are connected on locking inclined-plane: after buckling into the locking inclined-plane of snap seats, due to design inclined-plane and water
Plane included angle is big, and when attachment device is by outside pulling force, stiction effect will prevent buckle from falling off, and snap seats inclined-plane is tolerable
Rigging error remains close-fitting using the active force of reset spring.
(3) guiding surface 124a can design different location or shape as indicated by Fig. 4 according to demand.
Above-mentioned display screen 10 and its attachment device 100, pedestal 122 are connected on cabinet 200, and the rotation of rotation section 132 connects
It is connected on shell, one end of rotation section 132 is connect with buckle 130, and the other end of rotation section 132 is connect with magnetic part 136, makes card
Button main body 134 is connect by rotation section 132 with magnetic part 136, since rotation section 132 is rotationally connected on bottom case 110, makes to rotate
Portion 132 drives buckle main body 134 to rotate relative to bottom case 110, and since buckle main body 134 is connected on support division 124, thus
It is connected to bottom case 110 securely on cabinet 200, realizes the connection of attachment device 100 and bottom case 110.When needing dismantling connection to fill
When setting 100, with magnetic tool 20 close to the side away from cabinet 200 of bottom case 110, magnetic tool 20 is made to attract magnetic part 136,
Magnetic part 136 is acted on down towards magnetic tool 20 by magnetic attraction and being moved, and magnetic part 136 is made to drive rotation section 132 relative to bottom case
110 rotations make to buckle main body 134 and slip away support division 124, can easily separate cabinet 200 and bottom case 110 at this time, realize connection
The disassembly of device 100.When needing installing and connecting apparatus 100, magnetic workpiece and bottom case 110 are moved close to cabinet 200 first, made
Bottom case 110 is held on cabinet 200；Then magnetic tool 20 is withdrawn, and makes to buckle main body 134 relative to the movement of bottom case 110, is made
Buckling the movement of main body 134 drives rotation section 132 to rotate relative to bottom case 110, until buckle main body 134 is connected in support division 124
On.The convenient for disassembly and assembly and fastness of above-mentioned attachment device 100 is preferable.Above-mentioned attachment device is simple and reliable for structure, operation side
Just, precision is higher, and cost is greatly lowered.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
