Example one

Referring to fig. 1 to 5, the present embodiment provides a housing; fig. 1 is a schematic view of a first state of a housing provided in the present embodiment, in which the structure of the housing in a disassembled state is simply shown; FIG. 2 is an enlarged view of a portion of FIG. 1 at A, clearly showing the relative positions of the waterproof button and the push switch in a first state; fig. 3 is a schematic view of a second state of the housing provided in the present embodiment, in which the structure of the housing in the mounted state is simply shown; FIG. 4 is an enlarged view of a portion of FIG. 3 at B, clearly showing the relative positions of the waterproof button and the push switch in a second state; fig. 5 is a schematic view of a waterproof key, with isometric views for clarity of presentation.

The casing that this embodiment provided is used for wall-hanging building intercom to the realization is fixed in outdoor external wall body with the form of hanging with the building intercom.

Referring to fig. 1 to 5 in combination with fig. 6, the housing 1 provided in this embodiment includes a housing body 10, a waterproof button 11, and a push switch 12. The push switch 12 is a conventional switch that can be triggered by pressing and can automatically rebound to reset by releasing, and can control the on/off of a device electrically connected with the push switch 12.

Mounting hole 102 has been seted up to casing body 10, and in mounting hole 102 was worn to locate by waterproof button 11 is movably, because waterproof button 11's circumference outer wall supported with mounting hole 102's circumference inner wall is sealed to lean on, this waterproof button 11 can both effectively prevent outdoor rainwater and dust etc. to enter into casing body 10's inside to make this casing 1 have good waterproof dustproof effect.

The push switch 12 is disposed inside the housing body 10 and connected to the waterproof button 11, and a pushing direction of the push switch 12 is the same as a movable direction of the waterproof button 11. As shown in fig. 3, the waterproof button 11 moves toward the inside of the housing body 10 when pressed, and the moving direction is the same as the pressing direction of the push switch 12, so the waterproof button 11 presses the push switch 12. Similarly, after the pressing is finished, the waterproof button 11 is released and rebounds, and the press switch 12 loses pressure and restores to a natural state. Therefore, the waterproof and dustproof effect of the shell can be improved by avoiding the leak of the shell caused by the arrangement of the externally-leaked keys or switches on the premise of keeping the normal switch function of the push type switch 12.

As shown in fig. 1, in the disassembled state, since the installation side plate 101 is separated from the external wall, the external force action of the push switch 12 is lost, the push switch 12 is bounced to reset under the action of the self restoring force, and since the waterproof button 11 is connected with the push switch 12, the waterproof button 11 is also pushed back to the initial position under the action of the push switch 12, the anti-disassembling mode is destroyed, the alarm mechanism is started, and the alarm signal can be timely sent to the background personnel.

The housing 1 in this embodiment includes a housing body 10, a waterproof button 11, and a push switch 12. Casing body 10 is including offering the installation curb plate 101 of installing through-hole 102, and waterproof button 11 supports with the circumference inner wall of installing through-hole 102 is sealed to lean on to can effectively prevent external rainwater and dust etc. to enter into casing body 10's inside through this waterproof button 11, with the waterproof dustproof performance that improves this casing 1. In addition, the push switch 12 is disposed inside the housing body 10 and connected to the waterproof button 11, so that the push switch can be controlled to be opened or closed by pressing or releasing the waterproof button 11.
