[0048] Reference Figures 1 to 5 The utility model provides an outbound call box that is easy to repair, which is suitable for being installed on a wall 1 having a decorative groove 11 extending in the height direction, comprising:

[0049] The bottom shell 2 is detachably mounted in the decorative groove 11 of the wall 1, and when the bottom shell 2 is mounted in the decorative groove 11, at least one of the upper side surface 21 or the lower side surface 22 of the bottom shell 2 in the height direction has a first distance from the end surface of the decorative groove 11.

[0050] The bottom shell 2 has a first opening 23 on a side facing away from the wall 1 , and at least one of the upper side 21 or the lower side 22 of the bottom shell 2 in the height direction has a second opening 24 ;

[0051] a front cover 3 configured to be connected to the bottom housing 2 to seal the first opening 23;

[0052] The locking structure 4 is configured to detachably connect the front cover 3 and the bottom shell 2 , and the second opening 24 is configured to allow a disassembly tool to pass through and contact the locking structure 4 located in the first opening 23 to release the connection between the front cover 3 and the bottom shell 2 .

[0053] In this embodiment, the decorative groove 11 can be a groove with both ends open, one end open and the other closed, or both ends closed. When the bottom shell 2 is installed in the decorative groove 11, at least one of the upper side surface 21 and the lower side surface 22 of the bottom shell 2 along the height direction is spaced apart from the end surface of the decorative groove 11 by a first distance, and the second opening 24 is provided on the upper side surface 21 or the lower side surface 22 that maintains the first distance from the end surface of the decorative groove 11. In this embodiment, the decorative groove 11 is preferably a groove with both ends open.

[0054] The present invention provides a locking structure 4 between the front cover 3 and the bottom shell 2, and provides a second opening 24 for a disassembly tool to pass through on at least one of the upper side 21 or the lower side 22 of the bottom shell 2. When the front cover 3 needs to be removed for maintenance, a disassembly tool (such as a screwdriver) can be used to pass through the second opening 24 into the first opening 23 to contact (such as pressing) the locking structure 4 and trigger the specific structure of the locking structure 4 to release the connection between the front cover 3 and the bottom shell 2, thereby removing the front cover 3. Compared with the bolt connection method in the prior art, there is no need to screw multiple bolts. The front cover 3 can be removed by simply pressing the locking structure 4 with a screwdriver. The disassembly and assembly are simple, which is conducive to improving maintenance efficiency.

[0055] In one embodiment, the locking structure 4 includes:

[0056] A first buckle 41 is fixedly disposed on the first surface 31 of the front cover 3 facing the first opening 23;

[0057] The second latch 42 is pivotally disposed in the bottom housing 2 about a second direction, and when the front cover 3 moves in a first direction perpendicular to the first surface 31, the second latch 42 is compressed by the first latch 41 to pivot from the first position to the second position about a pivot axis extending along the second direction, and pivots from the second position to the first position about the pivot axis after the compression of the first latch 41 is released;

[0058] The second direction is parallel to the first surface 31 and perpendicular to the first direction;

[0059] The first buckle 41 can cooperate with the second buckle 42 to limit the front cover 3 from moving along the first direction.

[0060] With such a configuration, when installing the front cover 3, it is only necessary to buckle the front cover 3 onto the bottom shell 2 along the first direction. The second buckle 42 pivots under the pressure of the first buckle 41 and pivots to the second position, and pivots back to the first position after the pressure of the first buckle 41 is released. In this way, the first buckle 41 can be buckled with the second buckle 42, thereby limiting the movement of the front cover 3 along the first direction, and thus fixing the front cover 3 on the bottom shell 2.

[0061] In another embodiment, the first buckle 41 includes:

[0062] The first fixing portion 411 is fixedly connected to the first surface 31 of the front cover 3;

[0063] The first hook portion 412 is connected to an end of the first fixing portion 411 away from the first surface 31 .

[0064] The second buckle 42 includes:

[0065] The pivot portion 421 is pivotally connected to the wall of the bottom shell 2 located in the first opening 23 , and one end of the pivot portion 421 away from the wall extends toward the first surface 31 ;

[0066] a biasing spring 422 configured to bias the pivoting portion 421 so as to pivot the pivoting portion 421 about the pivot axis toward a direction close to the first hook portion 412 ;

[0067] The second hook 423 is connected to the end of the pivot portion 421 away from the wall. The second hook 423 can be pressed by the first hook 412 to pivot around the pivot axis, and the second hook 423 can be buckled with the first hook 412 to limit the front cover 3 from moving along the first direction.

[0068] In this embodiment, the first hook portion 412 has a first inclined surface, and the second hook portion 423 has a second inclined surface. The second inclined surface is acted upon by the first inclined surface to pivot around the pivot axis.

[0069] With such a configuration, when installing the front cover 3, it is only necessary to buckle the front cover 3 onto the bottom shell 2 along the first direction. The first inclined surface of the first hook 412 of the first clip 41 can act on the second inclined surface of the second hook 423 of the second clip 42, thereby causing the second clip 42 to pivot from the first position to the second position around the pivot axis, so that the first hook 412 can pass over the second hook 423 to reach the buckled position. At this time, the second hook 423 pivots from the second position to the first position under the action of the bias spring 422, thereby buckling the first clip 41 and the second clip 42 to limit the movement of the front cover 3 along the first direction, that is, to fix the front cover 3 on the bottom shell 2.

[0070] With such arrangement, when the front cover 3 needs to be removed, the maintenance personnel can use a disassembly tool such as a screwdriver to pass through the second opening 24 and extend into the bottom shell 2, and use the screwdriver to force the second clip 42 to pivot from the first position to the second position around the pivot axis, contacting the connection relationship between the first clip 41 and the second clip 42, so that the front cover 3 can be directly removed.

[0071] In a further embodiment, the second buckle 42 further includes a trigger portion 424 connected to the pivot portion 421 and extending to one side of the pivot portion 421 . The trigger portion 424 can drive the pivot portion 421 to pivot around the pivot axis.

[0072] Preferably, the trigger portion 424 may be arranged such that, viewed along the height direction, the second opening 24 and the trigger portion 424 at least partially overlap.

[0073] With this arrangement, when the front cover 3 needs to be removed, maintenance personnel can insert a disassembly tool such as a screwdriver through the second opening 24 and into the bottom case 2. The screwdriver can then directly force the trigger portion 424 to rotate, allowing the front cover 3 to be quickly removed. To facilitate the maintenance personnel's deployment of the trigger portion 424, in this embodiment, the second direction is set to be horizontal. That is, the second latch 42 can rotate up and down about the second direction of the pivot axis. When the maintenance personnel use the screwdriver to actuate the trigger portion 424, they only need to push the trigger portion 424 downward or upward.

[0074] In addition, the bottom shell 2 also includes a first limiting portion 25; the front cover 3 also includes a second limiting portion 32, and when the front cover 3 is installed on the bottom shell 2, the second limiting portion 32 is located on the side of the first limiting portion 25 facing the bottom shell 2 and abuts against the second surface of the second limiting portion 32 facing the bottom shell 2.

[0075] The second limiting portion 32 includes:

[0076] A transverse extension portion 321 , one end of which is connected to the first surface 31 of the front cover 3 , and the other end of which extends along the first direction;

[0077] The abutting portion 322 is connected to the other end of the transverse extending portion 321 and extends along the height direction to abut against the second surface of the first limiting portion 25 .

[0078] In this embodiment, the locking structure 4 is arranged at the upper or lower part of the outbound call box. The so-called upper and lower parts are the upper side or the lower side relative to the center of the outbound call box, and the first limiting portion 25 and the second limiting portion 32 are arranged on the side opposite to the locking structure 4 with respect to the center of the outbound call box.

[0079] With such arrangement, the first limiting portion 25 and the abutting portion 322 of the second limiting portion 32 can limit the movement of the front cover 3 relative to the other end of the locking structure 4 along the first direction, thereby making the installation of the front cover 3 more stable.

[0080] In order to make the outbound call box more beautiful in appearance and prevent misoperation by non-maintenance personnel, a rubber plug for sealing the second opening 24 is provided at the second opening 24 .

[0081] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
