DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The present invention will be further described below in conjunction with the embodiments.

[0018] Example: See also Figure 1-Figure 8 The present invention provides a technical solution: a house rental information publicity and display device, comprising: Bracket body 1; The publicity and display part 2 includes a frame 21. A rotating shaft 22 for adjusting the rotation angle of the frame 21 is arranged on the inner side of the bracket body 1. A panel 23 is rotatably connected to the top of the frame 21 through a hinge. The frame 21 is slidably connected to an unfolding member 24 for adjusting the rotation angle of the panel 23 through a slide groove 211 provided on the side thereof. Among them, the unfolding member 24 includes a slider 241, the outer surface of the slider 241 is slidably connected to the inner wall of the slide groove 211, and a return spring 242 connected to the inside of the frame 21 is provided at the bottom of the slider 241. The side of the slider 241 away from the frame 21 is provided with an unfolding rod 243 that is rotatably connected to the side of the panel 23.

[0019] It also includes an adjusting portion 3, which includes a locking groove 31 and a working cavity 32. The locking groove 31 and the working cavity 32 are connected to each other. The interior of the working cavity 32 is rotatably connected to a rotating plate 33 via a rotating shaft, and one end of the rotating plate 33 passes through the working cavity 32 and extends to the outside.

[0020] The slider 241 is slidably connected to a positioning rod 2411 that fits the inner wall of the locking groove 31 through a sliding hole. The end of the positioning rod 2411 away from the working chamber 32 is provided with a strong spring 2412 connected to the inside of the slider 241. The end of the rotating plate 33 close to the locking groove 31 is rotatably connected to a push wheel 331 that fits the outer end of the positioning rod 2411.

[0021] The main body of the rotating shaft member 22 adopts a detachable structure, and the rotating shaft member 22 includes a fixed seat 221 and a rotating seat 222. The fixed seat 221 is fixedly connected to the inner side of the bracket body 1 at one end away from the rotating seat 222, and the rotating seat 222 is fixedly connected to the side of the frame 21 at one end away from the fixed seat 221 through a connecting rod. The fixed seat 221 is fixedly connected to an open sleeve 223 that rotates with the circumferential outer surface of the rotating seat 222 at one end close to the frame 21, and the circumferential outer surface of the rotating seat 222 is fixedly connected to an arc block 224 that matches the notch of the open sleeve 223.

[0022] An external tube 2211 is fixedly connected to the fixed seat 221 near the rotating seat 222. A ring plate 2221 is sleeved on the circumferential outer surface of the rotating seat 222, and a through hole 2222 is opened inside the ring plate 2221. An inner connecting rod 2212 adapted to the through hole 2222 is slidably connected to the inner wall of the external tube 2211. One end of the inner connecting rod 2212 away from the through hole 2222 is connected to the inner wall of the external tube 2211 through a spring group. In the initial state, the end of the inner connecting rod 2212 away from the external tube 2211 extends into the through hole 2222.

[0023] The back of the frame 21 is slidably connected with a smooth rod 212 through an ear block. The central axis of the smooth rod 212 coincides with the central axis of the inner connecting rod 2212. The diameter of the smooth rod 212 is smaller than the diameter of the inner connecting rod 2212. The end of the smooth rod 212 away from the inner connecting rod 2212 is close to the outer end of the rotating plate 33.

[0024] A reset rod 332 is mounted on one end of the rotating plate 33 close to the smooth rod 212 through a collar, and the back of the frame 21 is slidably connected to the outer surface of the circumference of the reset rod 332 through a sleeve.

[0025] refer to Figure 1-8 Usually, the composition of the publicity column includes a frame, a panel, a publicity picture and a bracket, etc. The frame and the panel are generally detachable. Every time the publicity picture is changed, the panel needs to be disassembled, which is very inconvenient to use. Therefore, there is an urgent need for an information publicity display device with a rotating panel. This design allows the publicity picture to be easily replaced. In order to overcome the above-mentioned defects, the present invention designs an information publicity and display device for house rental.

[0026] In actual application, the panel 23 on the publicity display part 2 is manually pulled (a handle is installed under the panel 23), and the panel 23 rotates around the top of the frame 21 with the help of the hinge. During the rotation of the panel 23, the expansion rod 243 on the expansion member 24 is driven to move outward synchronously. Under the action of traction, the expansion rod 243 "transforms from an inclined state to a horizontal state". Since one end of the expansion rod 243 is rotatably connected to the panel 23, and the other end of the expansion rod 243 is rotatably connected to the slider 241, during the state transformation of the expansion rod 243, driving the expansion rod 243 will drive the slider 241 to slide downward along the inner wall of the slide groove 211, and the return spring 242 is elastically deformed under pressure. When the reset spring 242 is compressed for a certain distance, manually pressing the unfolding rod 243 downward can not only accelerate the unfolding of the panel 23, but also quickly press the unfolding rod 243 down to a horizontal state (the reset spring 242 is further compressed). At the same time, the slider 241 slides to the bottom of the slide groove 211, and the positioning rod 2411 in the slider 241 quickly pops out of the locking groove 31 on the corresponding adjustment part 3 (the strong spring 2412 is initially in a compressed state). The positioning rod 2411 and the slide groove 211 are combined into a whole to prevent the slider 241 from automatically resetting, thereby improving the overall unfolding stability of the panel 23 and the unfolding member 24. This design allows the promotional screen to be easily replaced.

[0027] It should be emphasized in the present invention that the existing billboard frames generally adopt a fixed structure. Each time a promotional picture is loaded, the promotional picture tends to fall off automatically under the action of gravity. It generally requires manual support or the use of auxiliary tools to position it, which is very troublesome. In contrast, in the present case, the frame 21 can follow the unfolding of the panel 23 to achieve automatic rotation (it will only start when the panel 23 is opened), which not only further increases the rotation angle of the panel 23 and provides a larger loading field of view, but also the frame 21 can be tilted to prevent the loaded promotional picture from automatically falling off.

[0028] Specifically, when the panel 23 has completed its rotation, the positioning rod 2411 is quickly inserted into the locking groove 31, driving the push wheel 331 to push into the working chamber 32, driving the rotating plate 33 to rotate, and the outer end of the rotating plate 33 generates a thrust on the smooth rod 212, driving the inner connecting rod 2212 to quickly disengage from the through hole 2222 on the ring plate 2221. Since the rotating shaft 22 is connected to the lower half of the side of the frame 21 (the upper half has a larger gravity and can rotate automatically, and can only rotate in one direction), when the panel 23 is pulled, the frame 21 rotates synchronously and automatically, driving the rotating seat 222 to rotate around the inside of the fixed seat 221, and the arc block 224 fits into the notch of the open sleeve 223 and stops moving. At this time, the frame 21 completes the automatic rotation (the outer end of the inner connecting rod 2212 fits on the outer surface of the ring plate 2221).

[0029] The present invention needs to emphasize again that after the promotional images are loaded, the pull ring on the reset rod 332 is manually grasped with one hand to drive the rotating plate 33 to reset. At this time, the push wheel 331 pushes the positioning rod 2411 to reset. After the positioning rod 2411 is separated from the locking groove 31, under the combined action of the elastic force of the reset spring 242 and the gravity of the panel 23 (the panel 23 is tilted at a large angle), the slider 241 is driven to slide and reset quickly and automatically along the inner wall of the slide groove 211 (when the slider 241 reaches the top, the reset spring 242 is stretched in the opposite direction to buffer the panel 23), eliminating the trouble of manually pulling the panel 23 to reset. At the same time, the pressing force of the reset rod 332 on the inner connecting rod 2212 disappears, the frame 21 and the panel 23 are reset, and the inner connecting rod 2212 is driven to align with the through hole 2222 again. Under the action of the elastic force, the two are combined into a whole, realizing the automatic locking of the frame 21, and the operation is simple.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
