The attachment plate is an arc-shaped structure and has a accommodating groove on its outer arc plate surface; the connecting rollers are two and are respectively located at the two ends of the attachment plate, and both ends of the connecting rollers are provided with rotating arms and one end of the rotating arm is rotatably connected to the end of the attachment plate, and the connecting roller is used to clamp one end of the propaganda poster; the tensioning assembly is arranged on the inner arc surface of the attachment plate and the tensioning assembly is used to drive the two rotating arms to rotate around the connection between itself and the end of the attachment plate, and the two rotating arms rotate in relative or opposite directions. The structure of the present invention is simple, the poster can be quickly unfolded and fixed, and the vibration of the poster caused by loose attachment due to wind is avoided; the operation is convenient and the practicability is strong.

[0004] However, the existing propaganda racks for student management still have drawbacks in actual use: schools generally use campus rockery, ponds and other areas to promote campus activities. The terrain of the rockery area is not as flat as the normal road surface, so the propaganda racks used for publicity will also be affected by the terrain. When multiple propaganda racks are placed, the overall placement stability will be greatly reduced due to the terrain, so it needs to be improved. Summary of the invention

[0005] In order to solve the problem mentioned in the above background technology that schools generally use campus rockery, ponds and other areas to promote campus activities, and the terrain of the rockery area is not as flat as the normal road surface, then the propaganda racks used for propaganda will also be affected by the terrain. When multiple propaganda racks are placed, the overall placement stability will be greatly reduced due to the terrain. The present invention provides a propaganda rack for student management, which enhances its applicability by setting a connection module, a limit assembly and other structures, and then changing the angle of the connection between the two propaganda rack bodies; by setting a positioning assembly, a connection module and other structures, the connection stability of the two adjacent propaganda rack bodies is improved.

[0006] To achieve the above object, the present invention provides the following technical solution: a propaganda rack for student management, comprising a propaganda rack body, and further comprising:

[0007] A limit assembly, the limit assembly being clamped on one side of the promotional stand body;

[0008] A connecting module, which is placed outside the promotional stand body and connected to the limiting assembly;

[0009] The limiting assembly includes a connecting plate, and a gear shaft for clamping the connecting module is installed at the bottom of the top of the connecting plate;

[0010] The connection module includes a C-shaped plate movably connected to the promotional stand body, the top and bottom surfaces of the C-shaped plate are provided with gear grooves meshing with the gear shaft, a connecting bellows is installed on the side of the C-shaped plate away from the limiting assembly, and a clamping block is fixed to the side of the connecting bellows away from the C-shaped plate.

[0011] Preferably, a positioning component, the positioning component is movably connected inside the connecting module;

[0012] The positioning assembly includes a positioning plate, and the positioning plate is movably connected to the inside of the clamping block away from the two ends of the side connected to the corrugated pipe;

[0013] A bracket is installed on one side of the publicity rack body, and one of the brackets is slidably connected to the inside of the publicity rack body;

[0014] A movable component that is in contact with the limiting component is fixedly connected to one side of the bracket. When the two promotional rack bodies are spliced ​​together and need to be connected in an angled manner according to the actual placement site, the connection between the two promotional rack bodies will be blocked by their respective brackets or not in contact with each other due to the different placement angles. When the two are blocked and contacted, the placement area of ​​the bracket behind the promotional rack body can be adjusted to perform horizontal adjustment.

[0015] Preferably, a clamping column is movably connected to one side of the connecting plate, and the bottom end of the clamping column passes through the connecting plate and extends to the inside of the connecting module;

[0016] The first spring is sleeved on the outer side of the clamping column located above the connecting plate, and the clamping column is elastically connected to the connecting plate through the first spring. When the connecting plate moves upward, the clamping column will be synchronously driven to move upward from the inside of the connecting module, thereby releasing the limiting effect on the connecting module. While the first spring limits the clamping column, it can also make the clamping column move up and down in the connecting plate.

[0017] Preferably, the connecting plates are symmetrical about the transverse central axis of the promotional stand body, the contact ends of the connecting plates are both provided with bevels, and are both in contact with the movable component. The bevels at the contact ends of the two connecting plates make it possible for the two ends of the movable component to abut against the bevel ends of the two connecting plates when the movable component moves, causing the two connecting plates to move in opposite directions, thereby allowing the limiting component to release the limiting effect on the connecting module.

[0018] Preferably, one end of the connecting plate is slidably engaged with the inside of the publicity frame body, and the connecting plate is elastically connected to the publicity frame body via a second spring.

[0019] Preferably, an empty groove for allowing the C-shaped plate to rotate is opened at the upper end of the connecting plate, and the outer wall of the upper end of the gear shaft is provided with teeth meshing with the gear groove. The lower end of the gear shaft is movably connected to the promotional frame body. When the connecting plate is not moved upward, the gear shaft will mesh with the inner wall of the gear groove, thereby preventing the connecting module from rotating. Conversely, when the connecting plate moves upward, the teeth at the upper end of the connecting plate will gradually disengage from the inside of the gear groove, and at the same time, the smooth part of the lower end of the gear shaft will move into the inside of the gear groove, thereby releasing the clamping of the connecting module, so that the connecting module can rotate.

[0020] Preferably, a card slot is provided in the contact area between the card block and the limit assembly, and the card slot is engaged with the card column. Two limit slots that allow the positioning plate to move are symmetrically provided on one side of the card block. Initially, the connecting plate realizes the limitation of the limit assembly and the connecting module through the connection between the card column and the card slot. When the connecting plate moves upward, the card column will move upward synchronously to release the connection with the card slot, and the card block can move outward at this time; the two limit slots on one side of the card block play a stable limiting role in the movement of the positioning plate.

[0021] Preferably, a third spring is provided at one end of the positioning plate located inside the limiting groove of the clamping block, and the positioning plate is elastically connected to the clamping block via the third spring.

[0022] Preferably, the opposite ends of the third spring away from the connecting module are both provided with bevels, and the height of the positioning plate is the same as the height of the promotional stand body. The opening of the beveled end of the third spring makes it convenient for the two positioning plates to be smoothly moved in opposite directions through the bevel of the third spring when the two promotional stand bodies are spliced, so that the side of the other promotional stand body can be stuck in the middle of the two positioning plates, and the side of the promotional stand body can be tightly clamped by the elastic force of the third spring.

[0023] Preferably, the movable assembly comprises a fixed column fixedly connected to the bracket, one end of the fixed column is sleeved with a fourth spring, the outer wall of the fixed column is sleeved with a push plate, and the fourth spring is elastically connected to the fixed column through the push plate;

[0024] The fourth spring is in abutting connection with the connecting plate.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention enhances applicability by setting up the coordination of structures such as the connecting module and the limit assembly, and then by changing the angle of the connection between the two propaganda rack bodies, pulling the fourth spring to make the fourth spring resist the two connecting plates, so that the two connecting plates move away from each other, and the connecting plate releases the engagement with the gear groove through the gear shaft, and at the same time makes the clamping column disengage from the inside of the clamping groove to the outside, so that the connecting module can rotate, and when it rotates to the appropriate area, the pulling of the fourth spring is released, and the fourth spring is reset through the push plate, and the connecting plate is reset through the second spring, thereby realizing the change of the angle of the connection area of ​​the two propaganda rack bodies, thereby enhancing the convenience for students to use on campus.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0039] like Figures 1 to 10 As shown, the present invention provides a propaganda rack for student management, comprising a propaganda rack body 1, and further comprising:

[0040] A limit component 3, which is clamped on one side of the promotional stand body 1;

[0041] A connecting module 4 is placed outside the promotional stand body 1 and connected to the limiting assembly 3;

[0042] Positioning component 5, which is movably connected to the inside of the connecting module 4

[0043] The limiting assembly 3 includes a connecting plate 31, and a gear shaft 32 for clamping the connecting module 4 is installed at the bottom of the top of the connecting plate 31;

[0044] The connecting module 4 includes a C-shaped plate 41 movably connected to the promotional frame body 1, and the top and bottom surfaces of the C-shaped plate 41 are both provided with gear grooves 42 meshing with the gear shaft 32, and a connecting bellows 43 is installed on the side of the C-shaped plate 41 away from the limiting component 3, and a clamping block 44 is fixedly connected to the side of the connecting bellows 43 away from the C-shaped plate 41;

[0045] The positioning assembly 5 includes a positioning plate 51 , which is movably connected to the inside of the two ends of the clamping block 44 away from the side of the bellows 43 .

[0046] By setting the coordination of the positioning assembly 5 and the connecting module 4, the connection stability of the two adjacent promotional rack bodies 1 is improved. The connecting bellows 43 is pulled to expand and the length of the connecting bellows 43 is extended. After the promotional rack bodies 1 to be connected are placed, the sides of the promotional rack bodies 1 are pushed to the middle area of ​​the two positioning plates 51 through the two positioning plates 51, and the promotional rack bodies 1 to be connected are clamped by the elastic force of the third spring 52, thereby improving the stability of the connection area of ​​the two adjacent promotional rack bodies 1.

[0047] like Figure 2 , Figure 6 and Figure 7 As shown, two brackets 2 are installed on one side of the promotion stand body 1, and one of the brackets 2 is slidably connected to the inside of the promotion stand body 1;

[0048] A movable component 6 that is in contact with the limiting component 3 is fixedly connected to one side of the bracket 2 .

[0049] Adopting the above scheme: when two promotional rack bodies 1 need to be connected in an angled manner according to the actual placement site after being spliced, the connection between the two promotional rack bodies 1 will be blocked by their respective brackets 2 due to the different placement angles, or they will not contact each other. When the two are blocked or contacted, the placement area of ​​the bracket 2 behind the promotional rack body 1 can be adjusted to perform horizontal adjustment, thereby preventing the respective brackets 2 from blocking each other after the two promotional rack bodies 1 are spliced, thereby affecting the normal placement of the promotional rack body 1.

[0050] like Figure 3 , Figure 5 and Fig. 9 As shown, a clamping column 33 is movably connected to one side of the connecting plate 31, and the bottom end of the clamping column 33 passes through the connecting plate 31 and extends to the inside of the connecting module 4;

[0051] A first spring 34 is sleeved on the outer side of the clamping column 33 located above the connecting plate 31 , and the clamping column 33 is elastically connected to the connecting plate 31 through the first spring 34 .

[0052] By adopting the above solution, when the connecting plate 31 moves upward, it will simultaneously drive the clamping column 33 to move upward from the inside of the connecting module 4, thereby releasing the limiting effect on the connecting module 4. While the first spring 34 limits the clamping column 33, it can also make the clamping column 33 move up and down in the connecting plate 31.

[0053] like Figure 2 , Figure 6 , Figure 8 and Fig.10 As shown, the connecting plate 31 is symmetrical with respect to the transverse central axis of the publicity frame body 1 , and the contact ends of the connecting plate 31 are all provided with bevels and are in contact with the movable assembly 6 .

[0054] By adopting the above scheme, the angled contact ends of the two connecting plates 31 are opened so that when the movable component 6 moves, the two ends of the movable component 6 will contact the angled ends of the two connecting plates 31, causing the two connecting plates 31 to move in opposite directions, thereby allowing the limiting component 3 to release the limiting effect on the connecting module 4.

[0055] like Fig.10 As shown, one end of the connecting plate 31 is slidably engaged with the inside of the promotion frame body 1 , and the connecting plate 31 is elastically connected to the promotion frame body 1 via a second spring 35 .

[0056] like Figure 3 and Fig. 9 As shown, the upper end of the connecting plate 31 is provided with an empty groove for allowing the C-shaped plate 41 to rotate, the upper outer wall of the gear shaft 32 is provided with teeth meshing with the gear groove 42, and the lower outer wall of the gear shaft 32 is smooth and movably connected to the promotional frame body 1.

[0057] The above scheme is adopted: when the connecting plate 31 is not moved upward, the gear shaft 32 will engage with the inner wall of the gear groove 42, thereby preventing the connecting module 4 from rotating. On the contrary, when the connecting plate 31 moves upward, the teeth at the upper end of the connecting plate 31 will gradually disengage from the inside of the gear groove 42, and at the same time, the smooth part of the lower end of the gear shaft 32 moves into the inside of the gear groove 42, thereby releasing the clamping of the connecting module 4, so that the connecting module 4 can rotate.

[0058] like Figure 3 and Fig. 9 As shown, a clamping groove 45 is provided in the contact area between the clamping block 44 and the limiting assembly 3 , and the clamping groove 45 is clamped with the clamping column 33 . Two limiting grooves for enabling the positioning plate 51 to move are symmetrically provided on one side of the clamping block 44 .

[0059] The above scheme is adopted: in the initial state, the connecting plate 31 realizes the limitation of the limiting component 3 and the connecting module 4 by connecting the clamping column 33 with the clamping slot 45. When the connecting plate 31 moves upward, the clamping column 33 will move upward synchronously to release the connection with the clamping slot 45. At this time, the clamping block 44 can move outward; the two limiting grooves on one side of the clamping block 44 play a stable limiting role in the movement of the positioning plate 51.

[0060] like Figure 3 As shown, a third spring 52 is provided at one end of the positioning plate 51 located inside the limiting groove of the clamping block 44, and the positioning plate 51 is elastically connected to the clamping block 44 through the third spring 52;

[0061] The two third springs 52 have bevels at their opposite ends away from the connecting module 4 , and the height of the positioning plate 51 is the same as that of the promotional stand body 1 .

[0062] By adopting the above scheme: the opening of the beveled end of the third spring 52 makes it convenient when the two promotional rack bodies 1 are spliced, and the two positioning plates 51 can be smoothly moved in opposite directions through the bevel of the third spring 52, so that the side of the other promotional rack body 1 can be stuck in the middle of the two positioning plates 51, and the side of the promotional rack body 1 is tightly clamped by the elastic force of the third spring 52.

[0063] like Figure 8 As shown, the movable assembly 6 includes a fixed column 61 fixedly connected to the bracket 2, one end of the fixed column 61 is sleeved with a fourth spring 62, the outer wall of the fixed column 61 is sleeved with a push plate 63, and the fourth spring 62 is elastically connected to the fixed column 61 through the push plate 63;

[0064] The fourth spring 62 is in contact with the connecting plate 31 .

[0065] The working principle and use process of the present invention:

[0066] First, place multiple promotional rack bodies 1 according to the areas where they need to be placed, pull the fourth spring 62, and make the fourth spring 62 contact the two connecting plates 31, so that the two connecting plates 31 move away from each other, and the connecting plate 31 will release the engagement with the gear slot 42 through the gear shaft 32, and at the same time, the clamping column 33 will be disengaged from the inside of the clamping slot 45 to the outside, so that the connecting module 4 can rotate. When it rotates to a suitable area, release the pull on the fourth spring 62, and the fourth spring 62 will achieve a reset effect through the push plate 63, and the connecting plate 31 will achieve a reset effect through the second spring 35;

[0067] Secondly, the connecting bellows 43 can be expanded by pulling it to extend the length of the connecting bellows 43. After that, the promotional stand body 1 to be connected is placed, and the side of the promotional stand body 1 is pushed to the middle area of ​​the two positioning plates 51 through the two positioning plates 51, and the promotional stand body 1 to be connected is clamped by the elastic force of the third spring 52.
