Embodiment
Please refer to Figure 1A, it is the stereogram according to a kind of drawing device 100 of one embodiment of the invention.Drawing device 100 has the structure that is similar to drawer basically, mainly comprises first housing 110 and second housing 120.Second housing 120, first housing 110 that is slidingly connected, meaning i.e. second housing 120 can slide with respect to first housing 110.
In an embodiment of the present invention, second housing 120 connects slide rail 112, to slide with respect to first housing 110.Slide rail 112 can be arranged on first housing 110 or on other object.In an embodiment of the present invention, slide rail 112 is fixed in the inner face of first housing 110, and the outside of second housing 120 connects slide rail 112.Thus, second housing 120 just can slide with respect to first housing 110 along slide rail 112.In addition, the mode that is slidingly connected on second housing 120 and first housing 110 of can applying to has a variety of, seldom does at this and gives unnecessary details.
In second housing 120 accommodation space is arranged, can be used to holding electronic device 10.Second housing 120 is provided with a plurality of connectors (not illustrating).When electronic installation 10 was positioned in second housing 120, electronic installation 10 can be connected with connector.As previously mentioned, connector can be connected with electronic building brick such as the power supply unit or the circuit board etc. in the external world.In an embodiment of the present invention, connector connects electric wire 12, sees through electric wire 12 and is connected to extraneous electronic building brick such as power supply unit (not illustrating).
In an embodiment of the present invention, spring 140 is a kind of torsion spring, and it has two arms 142 and 144 and is connected to bend 146.When the angle between arm 142 and the arm 144 changes, can change the degree of crook of bend 146, make bend 146 produce elastic restoring force and be sent to two arms 142 and 144.
In an embodiment of the present invention, two arms 142 and 144 are connected the protection chain 130 and first housing 110 respectively.Particularly, the bend 146 of spring 140 is fixed on the surface 114 of first housing 110, arm 144 abutment surface 114, and arm 142 butts protection chain 130.
Please also refer to Figure 1A and Figure 1B.Figure 1A and Figure 1B all are stereograms of drawing device 100, and two figure represent that respectively second housing 120 is with respect to the situation before and after 110 slips of first housing.
As previously mentioned, second housing 120 can slide with respect to first housing 110 along slide rail 112,, or second housing 120 is pushed and takes in first housing 110 away from first housing 110 for the user pulls out second housing 120.
When second housing 120 was pulled out, the end that second housing 120 can drive protection chain 130 moved together.Because the other end of protection chain 130 is to be fixed on first housing 110; so protection chain 130 can whole piece translation together; make the alteration of form of protection chain 130 but each chain monomer 150 rotates, and then make 130 elongations of protection chain, shown in Figure 1B.
In protection chain 130 elongation process, the part protection chain 130 of abutment arms 142 may make that the angle between two arms 142 and 144 changes away from the surface 114 of first housing 110, and then makes spring 140 produce elastic restoring force.Elastic restoring force can see through arm 142 and be applied on the protection chain 130, and the direction of elastic restoring force is the surface 114 towards first housing 110.
On the other hand, when second housing 120 along slide rail 112 when first housing 110 moves, the end that second housing 120 drives protection chains 130 moves.As previously mentioned, its length is shunk in the not translation together of protection chain 130 integral body but meeting is crooked.Shown in Figure 1A.
