The fixing base 210 includes a fastening portion 310, and the fastening portion 310 can be inserted into the fastening groove 301.

[0040] With the fastening groove 301 and fastening part 310 provided in this embodiment, the fastening part 310 is inserted into the fastening groove 301, which better realizes the fastening connection between the fixing seat 210 and the mounting seat 200. When actually fastened, the lower side of the fixing seat 210 abuts against the upper end face of the hook part 300.

[0041] Combination Figure 4As shown, in this embodiment, the hook portion 300 is provided with a first horizontal groove 302 with an opening facing the advertising machine body 110. A blocking plate 400 is provided at the opening of the first horizontal groove 302. A locking block 410 is provided in the first horizontal groove 302 by a first spring 401. A locking tongue block 411 is provided on the locking block 410. The first spring 401 is used to push the locking block 410 to move into the first horizontal groove 302, causing the locking tongue block 411 to extend into the fastening groove 301. The fastening portion 310 is provided with a slot 311 for the locking tongue block 411 to be inserted. The hook portion 300 is provided with a first driving member for driving the locking block 410 to move out of the first horizontal groove 302, causing the locking tongue block 411 to retract into the first horizontal groove 302.

[0042] In this embodiment, a first stepped groove is provided at the opening of the first horizontal groove 302. The blocking plate 400 is installed in the first stepped groove by bolts to block the first horizontal groove 302. In actual use, the blocking plate 400 is provided with multiple first springs 401. The multiple first springs 401 provide a large elastic force to push the locking block 410 to move into the first horizontal groove 302, and drive the locking tongue block 411 to extend into the latching groove 301.

[0043] The slot 311 and the first driving member are designed so that the fastening part 310 can be inserted into the fastening groove 301 and the locking tongue block 411 can be inserted into the slot 311, so that the fastening part 310 is locked. Thus, when the fixed seat 210 and the mounting seat 200 are fastened together, the locking member can lock them, thus making the fastening effect better.

[0044] The first driving component can drive the locking block 410 to move out of the first horizontal groove 302, thereby causing the locking tongue block 411 to retract into the first horizontal groove 302, releasing the locking of the fastening part 310, thus making the disassembly and assembly of the advertising machine body 110 more convenient.

[0045] Combination Figure 4 and Figure 5 As shown, in this embodiment, the locking block 410 is provided with a first groove 412, the first groove 412 is provided with a first guide slope 413, and the locking block 410 is provided with a slot 414 with one end connected to the first groove 412 along its moving direction.

[0046] The upper end face of the hook portion 300 is provided with a first vertical groove 303 that is perpendicular to the first horizontal groove 302 and communicates with the first horizontal groove 302. The first driving member includes a pressure plate 500 located in the first vertical groove 303. The upper end of the pressure plate 500 extends out of the first vertical groove 303. The lower end of the pressure plate 500 forms a guide portion 501 that extends into the first groove 412 and cooperates with the first guide inclined surface 413. The pressure plate 500 is provided with a slot 502 located at the guide portion 501. When the fixing seat 210 is fastened to the mounting seat 200, the fixing seat 210 presses down the pressure plate 500, driving the guide portion 501 to squeeze the first guide inclined surface 413 and push the locking block 410 to move out of the first horizontal groove 302. When the guide portion 501 slides into the slot 502, the first spring 401 pushes the locking block 410 to reset.

[0047] In this embodiment, during actual use, when the fastening part 310 is not inserted into the fastening groove 301, the first spring 401 pushes the locking block 410 to the innermost end of the first horizontal groove 302. At this time, the guide part 501 of the pressure plate 500 located in the first vertical groove 303 extends into the first groove 412 and abuts against the upper end of the first guide slope 413. The upper end of the pressure plate 500 remains extended out of the first vertical groove 303. When the fastening part 310 is inserted into the fastening groove 301, the lower side of the fixing seat 210 abuts against the upper end of the hook part 300, which can drive the pressure plate 500 to move downward in the first vertical groove 303, so that the guide part 501 presses the first guide slope 413 and pushes the locking block 410 to move outward toward the first horizontal groove 302, that is, to realize the retraction of the locking tongue block 411. When the guide part 501 moves to the lowermost end of the first guide slope 413, the locking tongue block 411 can be fully retracted. Even if the fastening part 310 can continue to be inserted into the fastening groove 301, at this time, if the fastening part 310 is continued to be inserted into the fastening groove 301 until it is fully inserted, the pressure plate 500 can be moved down to the position, driving the guide part 501 to move into the slot 414. At this time, under the action of the first spring 401 and in conjunction with the setting of the slot 502, the locking block 410 can be reset so that the locking tongue block 411 extends out and is locked into the slot 311 to lock the fastening part 310. With the above structure, the locking member can be automatically locked as the fixing seat 210 is fastened on the mounting seat 200, making the installation of the advertising machine body 110 on the elevator car wall 100 faster and more convenient.

[0048] In order to facilitate the cooperation between the pressure plate 500 and the locking block 410, the locking block 410 is provided with notches 416 on both sides of the first groove 412. By using the notches 416 and the matching groove 502, the guide part 501 can slide in the slot 414 better.

[0049] In this embodiment, in order to facilitate the user to drive the locking block 410 after it is fastened to move toward the opening of the first horizontal groove 302, that is, to release the locking member from the fastening part 310, a limiting slide groove is provided on the side wall opposite to the first horizontal groove 302 along its extension direction. The locking block 410 is provided with a positioning hole 417 corresponding to the limiting slide groove. In actual use, the locking block 410 can be moved toward the opening of the first horizontal groove 302 by using a lever that passes through the limiting slide groove and extends into the positioning hole 417 and moving along the limiting slide groove.

[0050] In order to enable the pressure plate 500 to automatically extend out of the first vertical groove 303 and reset when the lever is turned to release the locking of the fastening part 310, so as to facilitate re-fastening, the first vertical groove 303 has mounting step grooves on both sides. The upper end of the pressure plate 500 protrudes outward to form a mounting platform 504. A fourth spring 503 is installed in the mounting step groove to push the mounting platform 504 upward. Using the elastic force of the fourth spring 503, when the lever is turned to move the locking block 410 outward toward the first horizontal groove 302 and drive the locking tongue block 411 to retract completely, the guide part 501 can slide out from the connection between the first groove 412 and the slot 414 to reset it.

[0051] Combination Figure 3 As shown in this embodiment, in order to prevent the fastening part 310 from sliding horizontally after being fastened and causing it to detach from the mounting base 200, the fixed base 210 is provided with protective plates 320 on both sides of the mounting base 200. In actual use, the protective plate 320 is provided with a limiting groove 321 for the lever to extend from the limiting slide groove. With this structure, it is easy to move the lever to release the locking of the locking part and to facilitate the disassembly of the advertising machine body 110.

[0052] Combination Figure 6 and Figure 7 As shown, in this embodiment, the mounting base 120 includes a mounting plate 600 and sliding plates 610 arranged parallel to both sides of the mounting plate 600.
