Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, and in particular relates to an elevator intercom device. Background Technology

[0002] An elevator is a vertical transportation device that transports people or goods. It mainly consists of a machine room, a shaft and pit, a car, and landings. It uses traction ropes and traction sheaves to provide traction force, thereby realizing the lifting and lowering movement of the car and counterweight to achieve the purpose of transportation.

[0003] Elevator intercom systems are used for passengers to communicate two-way with people outside the elevator in emergencies, greatly facilitating elevator maintenance. To prevent the intercom system from being bumped by people and for ease of use, it is usually installed inside the elevator control panel, with the control buttons installed on the surface of the panel. When the intercom system is damaged and needs maintenance, the entire control panel needs to be disassembled, which is a complicated process that prolongs maintenance time. Furthermore, the exposed installation makes it susceptible to accidental activation due to bumps from people. Utility Model Content

[0024] like Figures 1 to 5As shown in the figure, an elevator intercom device provided by this utility model embodiment includes a control panel 1 and an intercom assembly 2. The control panel 1 includes a mounting plate 101 and two side frames 102. The rear sides of the two side frames 102 are fixedly connected to the left and right sides of the front side of the mounting plate 101, respectively. The intercom assembly 2 includes a mounting frame 201, a front plate 202, two fixing ears 203, and an intercom 204. The surface of the mounting frame 201 is movably connected to the bottom of the interior of the mounting plate 101. The front plate 202 is installed on the front side of the mounting frame 201 by a snap-fit ​​structure. The opposite sides of the two fixing ears 203 are fixedly connected to the left and right sides of the interior of the mounting frame 201, respectively. The intercom 204 is located inside the mounting frame 201, and the rear side of the intercom 204 is fixedly connected to the interior of the two fixing ears 203 by bolts. The control panel 1 is used to control the operation of the elevator.The intercom component 2 is used for emergency calls. To facilitate the installation of the intercom device, multiple mounting seats 3 are fixedly connected inside the mounting frame 201. A plug-in component 4 is provided inside the mounting frame 201, and a transmission component 5 is provided at the bottom inside the mounting frame 201. The plug-in component 4 is inserted into the mounting plate 101 to restrict the movement of the mounting frame 201, thereby keeping the mounting frame 201 stable inside the mounting plate 101. To ensure the mounting frame 201 is stably fixed to the mounting plate 101, the plug-in component 4 includes two threaded rods 401, two lifting blocks 402, and four insertion rods 403. The surfaces of the two threaded rods 401 are movably connected to the interiors of the left and right mounting seats 3, respectively. The surfaces of the two lifting blocks 402 are respectively connected to the interiors of the left and right sides of the mounting frame 201. The two lifting blocks 402 are threadedly connected to the surfaces of the two threaded rods 401. The bottoms of the four insert rods 403 are fixedly connected to the tops of the two lifting blocks 402, and the surfaces of the four insert rods 403 are inserted into the interior of the mounting plate 101. The two threaded rods 401 drive the lifting blocks 402 to move upward, and the insert rods 403 are inserted into the interior of the mounting plate 101, restricting the movement of the mounting frame 201, thereby fixing the mounting frame 201 and the mounting plate 101 stably. In order to drive the two threaded rods 401 to rotate, the transmission assembly 5 includes a rotating block 501, two transmission seats 502, and two transmission racks 503. The top and bottom surfaces of the rotating block 501 are movably connected to the interiors of the two middle mounting seats 3, and the interiors of the two transmission seats 502 are divided into... The two transmission racks 503 are fixedly connected to the top and bottom of the rotating block 501. The sides of the two transmission racks 503 near the two transmission seats 502 are engaged with the surfaces of the two transmission seats 502. The sides of the two transmission racks 503 near the two threaded rods 401 are also engaged with the surfaces of the two threaded rods 401. Rotating the rotating block 501 causes the two transmission seats 502 to rotate. During the rotation of the two transmission seats 502, the two transmission racks 503 move. During the movement of the two transmission racks 503, the two threaded rods 401 rotate. To facilitate the removal of the intercom assembly 2, a compression spring 6 is fixedly connected to the rear side inside the mounting plate 101. A push plate 7 is fixedly connected to the front side of the compression spring 6. The front side of the push plate 7 is movably connected to the rear side of the intercom 204. By using the combined action of the compression spring 6 and the push plate 7, the walkie-talkie 204 is moved from inside the mounting plate 101, thus removing the walkie-talkie 204. To prevent accidental activation due to impact, a baffle 8 is provided on the front side of the walkie-talkie 204. A fixed shaft 9 is movably connected to the top of the inside of the baffle 8. The left and right sides of the fixed shaft 9 are fixedly connected to the opposite ends of the two side frames 102, respectively. The baffle 8 blocks the front of the walkie-talkie 204 to prevent it from being impacted. To keep the baffle 8 stable, magnetic strips 10 are fixedly connected to the left and right sides inside the baffle 8. The surfaces of the two magnetic strips 10 are magnetically connected to the surfaces of the two side frames 102. The connection between the magnetic strips 10 and the side frames 102 keeps the baffle 8 stable.

[0025] The working principle of this utility model:

[0026] In case of an emergency call, the baffle 8 is moved upwards and rotated around the fixed axis 9 to move to the top of the walkie-talkie 204. An emergency call can then be made through the walkie-talkie 204. When the walkie-talkie 204 needs to be disassembled for maintenance, the front plate 202 is snapped off, and the rotating block 501 is rotated, causing the two transmission seats 502 to rotate. During the rotation of the two transmission seats 502, the two transmission racks 503 are moved, and during the movement of the two transmission racks 503, the two threaded rods 401 are rotated. During the rotation of the two threaded rods 401, the four insertion rods 403 are moved downwards through the two lifting blocks 402. After the insertion rods 403 are disengaged from the mounting plate 101, the compression spring 6 rebounds, and the push plate 7 pushes the walkie-talkie 204 out of the mounting plate 101, thereby removing the walkie-talkie 204 for maintenance.
