[0032] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] Example:

[0034] like Figures 1-6 As shown, a surface-mounted building intercom door station includes:

[0035] The intercom door station body 1 has threaded mounting holes symmetrically opened on its rear surface;

[0036] The connecting mounting component 2 is bolted to the rear surface of the intercom door station body 1;

[0037] The connecting positioning component 3 is movably sleeved on the outer surface of the connecting mounting component 2;

[0038] The connecting locking component 4 is bolted between the connecting positioning components 3;

[0039] The drive adjustment component 5 is connected and is movably sleeved on the outer side of the input end surface of the locking component 4.

[0040] The working principle of the above technical solution is as follows:

[0041] During use, the connecting positioning component 3 can be installed and fixed to the wall using expansion bolts. Then, the intercom door station body 1 and the connecting installation component 2 are moved so that the connecting installation component 2 can be inserted into the inside of the connecting positioning component 3. Next, the connecting driving adjustment component 5 drives the connecting locking component 4 so that the connecting locking component 4 can lock the connection between the connecting installation component 2 and the connecting positioning component 3. Finally, the connecting driving adjustment component 5 is disassembled, which improves the overall connection safety and stability and makes operation convenient.

[0042] In another embodiment, such as Figure 3As shown, the connection and installation assembly 2 includes a first connecting plate 21, and a connecting plug 22 is fixedly connected between the ends of the first connecting plate 21. A first positioning hole 23 is provided on the side of the surface of the connecting plug 22 that is close to each other.

[0043] This facilitates the connection of the first connecting plate 21 to the intercom door unit body 1 using bolts, allowing the connecting plug 22 to be stably inserted into the inner side of the connecting positioning component 3, thus enabling initial connection.

[0044] In another embodiment, such as Figure 3 As shown, the connecting positioning component 3 includes a first connecting sleeve block 32, a second connecting plate 31 is fixedly connected to one side of the first connecting sleeve block 32, mounting holes are symmetrically opened on the surface of the second connecting plate 31, a fixing slot 33 is opened inside the first connecting sleeve block 32, and fixing threaded holes 34 and second positioning insertion holes 35 are opened on the sides of the first connecting sleeve block 32 that are close to each other, and the fixing threaded holes 34 are symmetrically located on both sides of the second positioning insertion holes 35.

[0045] This allows the second connecting plate 31 to be connected and fixed to the wall using expansion bolts, thereby installing and fixing the first connecting sleeve 32. At the same time, the fixing threaded hole 34 and the second positioning insertion hole 35 can be used in conjunction with the connecting locking component 4, making the operation convenient and quick.

[0046] In another embodiment, such as Figure 4 As shown, the inner side of the first connecting sleeve block 32 is in contact with the outer surface of the connecting plug block 22, and the second positioning hole 35 is aligned with the first positioning hole 23.

[0047] This allows the connecting plug 22 to be stably inserted into the inner side of the fixing slot 33, while also aligning the second positioning hole 35 and the first positioning hole 23 with each other, enabling better cooperation with the connecting locking component 4 and facilitating operation.

[0048] In another embodiment, such as Figure 5As shown, the connecting locking assembly 4 includes a connecting leg 41. A second connecting sleeve 42 is fixedly connected to the end of the connecting leg 41. A movable rotating rod 43 is movably connected inside the top of the second connecting sleeve 42. A first limiting collar 45 is fixedly sleeved on the outer surface of the movable rotating rod 43. A rectangular driving block 44 is fixedly connected to the top of the movable rotating rod 43. A driving bevel gear 46 is fixedly connected to the bottom of the movable rotating rod 43. Fixed base blocks 47 are symmetrically provided on the inner bottom of the second connecting sleeve 42. A movable threaded rod 48 is movably connected inside the fixed base block 47. A fixed limiting collar is fixedly connected to one end of the movable threaded rod 48. The end plate 410 has a second limiting collar 49 fixedly sleeved on the outer surface of the movable threaded rod 48. A driven bevel gear 411 is fixedly connected to one side of the fixed limiting end plate 410. A movable positioning threaded sleeve 414 is movably sleeved on the outer surface of the movable threaded rod 48 through a thread. A fixed guide block 415 is symmetrically provided at one end of the movable positioning threaded sleeve 414. Fixed guide rods 412 are symmetrically provided at both ends of the inner side of the second connecting sleeve block 42. A fixed limiting end block 413 is fixedly connected to one end of the fixed guide rod 412. Through holes adapted to the movable positioning threaded sleeve 414 are opened at both ends of the second connecting sleeve block 42.

[0049] The rectangular drive block 44 can be driven by the connecting drive adjustment component 5, which in turn drives the movable rotating rod 43, the first limiting collar 45, and the driving bevel gear 46 to rotate, thereby driving the driven bevel gear 411 to rotate. This causes the fixed limiting end plate 410, the movable threaded rod 48, and the second limiting collar 49 to rotate, which in turn allows the movable positioning threaded sleeve 414 to move on the outer side of the surface of the movable threaded rod 48. At the same time, the fixed guide block 415 can move on the outer side of the surface of the fixed guide rod 412. The end of the movable positioning threaded sleeve 414 can be inserted into the inner side of the first positioning hole 23 and the second positioning hole 35 for connection and locking, making operation convenient.

[0050] In another embodiment, such as Figure 5 As shown, the interior of the fixed guide block 415 slides against the outer surface of the fixed guide rod 412, and the driven bevel gear 411 and the driving bevel gear 46 are perpendicularly meshed with each other.

[0051] This allows the driving bevel gear 46 to stably transmit power to the driven bevel gear 411, while the fixed guide block 415 can move stably on the outer side of the surface of the fixed guide rod 412, making operation convenient.

[0052] In another embodiment, such as Figure 6As shown, the connecting drive adjustment assembly 5 includes a drive sleeve 51, a connecting drive rod 52 is fixedly connected to the top of the drive sleeve 51, a drive top plate 53 is fixedly connected to the top of the connecting drive rod 52, and a groove adapted to the rectangular drive block 44 is provided at the bottom of the drive sleeve 51.

[0053] The drive sleeve 51 can be fitted onto the outer surface of the rectangular drive block 44 to rotate the drive top plate 53, thereby driving the connecting drive rod 52 and the drive sleeve 51 to rotate, thus driving and adjusting the connecting locking assembly 4, which is convenient to operate.

[0054] The working principle of this utility model is as follows: First, the connecting leg 41 and the first connecting sleeve 32 are connected and installed using the fixing threaded hole 34 and bolts. Next, the second connecting plate 31 is installed and fixed to the wall using expansion bolts. Then, the first connecting plate 21 is installed and fixed to the intercom door station body 1 using bolts. Next, the intercom door station body 1 and the connecting installation assembly 2 are moved as a whole, allowing the connecting plug 22 to be inserted into the inner side of the fixing slot 33, aligning the first positioning hole 23 and the second positioning hole 35. Finally, the driving sleeve 51 is fitted onto the outer surface of the rectangular driving block 44, and the driving top plate 53 is rotated, causing the connecting driving rod 52 and the driving sleeve 51 to rotate, which in turn causes the rectangular driving block 44 to rotate, driving the movable rotating rod 43, the first connecting sleeve 52, and the second connecting sleeve 52 to rotate. A limiting collar 45 and an active bevel gear 46 rotate, driving a driven bevel gear 411 to rotate, causing the fixed limiting end plate 410, the movable threaded rod 48, and the second limiting collar 49 to rotate. This allows the movable positioning threaded sleeve 414 to move on the outer side of the movable threaded rod 48, while the fixed guide block 415 can move on the outer side of the fixed guide rod 412. The end of the movable positioning threaded sleeve 414 can be inserted into the inner side of the first positioning hole 23 and the second positioning hole 35, thereby locking the connection. Finally, the entire connection drive adjustment assembly 5 can be disassembled to improve the overall connection safety. Conversely, it can also quickly disassemble the connection installation assembly 2 and the connection positioning assembly 3, thereby quickly disassembling the intercom door station body 1. The overall structure is simple and the operation is convenient and quick.

[0055] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
