Plate 17, one end that the first fagging 17 is abutted with the first cover board 3 be the first plane 19, the first plane 19 can under the first cover board 3
Side wall fitting, the first plane 19 increase the contact surface with the first cover board 3.It is also tiltedly installed in lower case 1 and the second cover board 4
The second fagging 18 that lower wall abuts, one end that the second fagging 18 is abutted with the second cover board 4 are the second plane 20, the second plane 20
The same contact surface increased with the second cover board 4.When first cover board 3 and the second cover board 4 are turned down, 4 meeting of the first cover board 3 and the second cover board
It is placed on the upper end side wall of lower case 1, since the side wall of lower case 1 is relatively thin, the first cover board 3 makes with the second cover board 4 for a long time
It, can be more preferably stable to the first cover board 3 and by the first fagging 17 and the second fagging 18 with being easy to smash lower case 1 in the process
Two cover boards 4 are supported, impact when the first cover board 3 of reduction and the second cover board 4 are turned down to 1 upper side wall of lower case.
As shown in Figure 3, Figure 4, the first cover board 3 is towards being fixedly connected with the first sealing strip on one end side wall of the second cover board 4
21, the second sealing strip 22 being bonded with the first sealing strip 21 is fixedly connected on the second cover board 4.When the first cover board 3 and the second lid
After plate 4 is turned down and fixed, the first sealing strip 21 can be bonded to each other abutting with the second sealing strip 22, thus to the first cover board 3
Gap between the second cover board 4 is filled up, can be to gap when at the gap that water splashes the first cover board 3 and the second cover board 4
Place is sealed, and water is avoided to flow into lower case 1 along gap.
The specific effect of the present embodiment is as follows:
When needing to separate the first cover board 3 with the second cover board 4, first inserted link 14 is extracted out of slot 15, then by push plate 9
It slides to the direction far from the second cover board 4, after will connect block 12 down and be skidded off out of card slot 8, just the first cover board 3 can be covered with second
Both ends turn down plate 4 to the left and right respectively, to just realize the separation to the first cover board 3 and the second cover board 4.To the first cover board 3
When being fixed with the second cover board 4, first the second cover board 4 is turned down, push plate 9 is then slided and connects the first groove 5 of slide-in of block 12 by under
It is interior, then the first cover board 3 is turned down, when perforation 7 is directed at card slot 8 under the action of spring 10, under connect block 12 and just can spring into card slot 8
It is interior, then be fixed block 12 is connect under in the insertion slot 15 of inserted link 14 on the second cover board 4.The process of removing and installing does not need
By other tools, have the effect of conveniently dismantling shell.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
