DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 to Figure 8 As shown, the present embodiment proposes an advertising gate for quickly changing pictures, comprising a gate frame 1, an advertising frame 2 is fixedly connected to the inner side of the gate frame 1, a frame door 5 is hinged at one end of the outer side of the advertising frame 2, and a transparent window 6 is fixedly connected to the middle part of the frame door 5; a winding mechanism 3 is arranged at the top end of the inner side of the advertising frame 2, the winding mechanism 3 comprises a roller 31 for winding up the advertising page, both ends of the roller 31 are fixedly connected with connecting members 32, the top ends of both sides of the advertising frame 2 are rotatably connected with clamping members 33 that slide with the connecting members 32, an installation groove 34 is opened on the outer side of the roller 31, a pressing member 35 for fixing the top end of the advertising page 2 in the installation groove 34 is arranged on the inner side of the installation groove 34, and a positioning mechanism 4 for fixing the bottom end of the advertising page is arranged at the bottom end of the inner side of the advertising frame 2.

[0028] During disassembly, the roller 31 can be taken out by disengaging the connecting pieces 32 on both sides of the roller 31 from the snap-fit ​​pieces 33, and then the advertising page on the roller 31 can be unfolded and the clamping piece 35 can be operated to disengage from the top of the advertising page, so that the advertising page can be quickly disassembled; during installation, the top of the new advertising page can be inserted into the installation groove 34 and the clamping piece 35 can be operated to clamp it, and then the new advertising page can be rolled up on the roller 31, so as to avoid damage to the advertising page during the installation process, and then the connecting pieces 32 on both sides of the roller 31 can be matched with the snap-fit ​​pieces 33, and then the advertising page on the roller 31 can be unfolded downward, and finally the bottom end of the advertising page can be fixed by the positioning mechanism 4. The entire installation process can be performed by only one person, and the operation process is very convenient.

[0029] Furthermore, the connecting member 32 includes an elastic telescopic rod 321, one end of which is fixedly connected to the roller 31, and the other end of the elastic telescopic rod 321 is fixedly connected to a connecting head 322, and the outer side of the connecting head 322 is fixedly connected to a limiting block 323. The clamping member 33 includes a sleeve 331, and the sleeve 331 passes through the inner wall of the advertising frame 2, and the sleeve 331 is rotatably connected to the inner wall of the advertising frame 2. A slot 332 is provided at one end of the sleeve 331, and the connecting head 322 and the limiting block 323 are both slidably matched with the slot 332. The other end of the sleeve 331 is fixedly connected to a rotating cap 333. During installation, the connector 322 at one end of the roller 31 is slid into the slot 332 of the corresponding sleeve 331, and then the roller 31 is acted on to apply pressure to the elastic telescopic rod 321, which causes the elastic telescopic rod 321 to contract, thereby reserving space for the connector 322 at the other end of the roller 31 to cooperate with the sleeve 331, so that the roller 31 can be quickly installed on the inner side of the advertising frame 2, and the sleeve 331 can be rotated by rotating the rotating cap 333, so that the connector 322 drives the roller 31 to rotate, so that the roller 31 can roll up or unfold the advertising page.

The relative sliding of the rod sleeve 3211 and the plug rod 3212 can change the overall length, and the elasticity of the spring 3214 itself can make the plug rod 3212 always apply pressure to the connector 322, so that the connector 322 and the card slot 332 of the card sleeve 331 are closely matched.

[0031] Furthermore, the clamping member 35 includes a pressing plate 351, which is slidably connected to the inner side of the mounting groove 34, and a sliding rod 352 is fixedly connected to the top of the pressing plate 351. The end of the sliding rod 352 away from the pressing plate 351 passes through the top wall of the mounting groove 34 and extends to the outside of the winding roller 31. The sliding rod 352 is slidably connected to the winding roller 31, and the end of the sliding rod 352 away from the pressing plate 351 is fixedly connected to a pulling block 353. A spring sheet 354 is sleeved on the sliding rod 352, and one end of the spring sheet 354 abuts against the pulling block 353, and the other end of the spring sheet 354 abuts against the pressing plate 351. When disassembling, by pulling the pull block 353 upwards, the slide bar 352 slides upwards, and the pressure plate 351 moves upward and separates from the advertising page; when installing, by pulling the pull block 353 upwards, the slide bar 352 slides upwards, and the pressure plate 351 moves upwards. At this time, the spring piece 354 is compressed to accumulate potential energy, and then the top of the advertising page is inserted into the installation groove 34, and then the pull block 353 is released. At this time, the spring piece 354 releases the potential energy, and the pressure plate 351 moves downward and presses the advertising page tightly and fixes it.

[0032] Furthermore, the positioning mechanism 4 includes a placement seat 41, which is fixedly connected to the bottom end of the inner side of the advertising frame 2. Both ends of the placement seat 41 are fixedly connected to the mounting frame 42. The inner sides of the two mounting frames 42 are provided with positioning members 43. The positioning members 43 include a second slide bar 431 that passes through the mounting frame 42. The second slide bar 431 is slidably connected to the mounting frame 42. One end of the second slide bar 431 is fixedly connected to the second pressure plate 432, and the other end of the second slide bar 431 is fixedly connected to the second pull block 433. The second slide bar 431 is provided with a spring piece 434, one end of the spring piece 434 is in contact with the second pressure plate 432, and the other end of the spring piece 434 is in contact with the inner wall of the mounting frame 42.

[0033] During installation, the slide bar 431 slides by pulling the pull block 433 outward, which causes the pressure plate 432 to slide and the gap between it and the support of the placement seat 41 increases. At this time, the spring piece 434 is compressed to accumulate potential energy, and then the bottom end of the advertising page is placed in the gap between the pressure plate 432 and the placement seat 41. Finally, the pull block 433 is released. At this time, the spring piece 434 releases the potential energy and makes the pressure plate 432 close to the placement seat 41, so that the pressure plate 432 fixes the bottom end of the advertising page on the placement seat 41.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
