As shown in fig. 1-8, the utility model provides a think political affairs education publicity column, including support frame 1, the box 2 of fixed mounting on support frame 1, fixed mounting bulletin board 3 and the clamping mechanism 4 of setting in bulletin board 3 both sides in box 2. The box 2 comprises two shells with one side hinged with each other and a transparent plate arranged on the shells, wherein the hinged part is preferably a top, so that posters can be conveniently posted.

The clamping mechanism 4 includes a base plate 41, a first housing 42, a connecting device 44, a pressure plate 43, and a first spring 45. The bottom plate 41 is fixedly connected with the bulletin board 3. The first housing 42 has one end hinged to the bulletin board 3 and the other end detachably connected to the bulletin board 3 by a connecting means 44. Preferably, both sides of the first housing 42 and both sides of the base plate 41 contact each other to help grip the poster. The pressing plate 43 is arranged in the first shell 42 in a sliding mode, the first springs 45 are arranged in the first shell 42, two ends of each first spring 45 are respectively abutted to the pressing plate 43 and the first shell 42, the first springs 45 bear pressure in a natural state to keep the pressing plate 43 abutted to the bottom plate 41, the number of the first springs 45 is multiple, the first springs are evenly distributed in the shell, the pressing plate 43 and the bottom plate 41 are enabled to be even in force, elastic force between the pressing plate 43 and the bottom plate 41 can be increased, and poster clamping is facilitated. The opposite sides of the base plate 41 and the pressure plate 43 are each provided with a rubber layer (not shown in the drawings) to increase the friction force for better clamping the poster. In use, the detachable connection end of the first housing 42 is first released. One end of the poster is then placed in the middle of the clamping mechanism 4 on one side. The first housing 42 is rotated until the pressing plate 43 completely abuts against the bottom plate 41, i.e., the poster is clamped. This structure utilizes both the pressure between the pressure plate 43 and the bottom plate 41 to clamp the poster and the side surfaces of the first housing 42 and the bottom plate 41 to clamp the poster, so that the poster is more stably fixed.

In one embodiment, the clamping mechanism 4 further includes a first screw 46 and a first nut 47, the first screw 46 is inserted into the first spring 45, one end of the first screw 46 is fixedly connected to the slider 51, the other end of the first screw passes through the first housing 42 and then is connected to the first nut 47, and the first screw 46 is slidably connected to the first housing 42. In this way, the relative position of the pressing plate 43 can be changed by adjusting the first nut 47, so as to change the moving distance when the pressing plate 43 collides with the bottom plate 41, so as to change the deformation amount of the first spring 45, and further change the magnitude of the clamping force, thereby facilitating the clamping of the poster.

In one embodiment, the coupling device 44 includes a mount 441, a link 442, and a cam handle 443. The first housing 42 is provided with a locking groove 421 at an end thereof away from the hinge center. The mounting seat 441 is fixedly connected with the bulletin board 3. The connecting rod 442 has one end hinged to the mounting seat 441 and the other end rotated around the hinge center line of the connecting rod 442 to a position where the connecting rod is inserted into the engaging groove 421. The cam end of the cam handle 443 is hinged to the other end of the link 442, and when the link 442 is engaged with the engaging groove 421, the cam end of the cam handle 443 interferes with the first housing 42 as the other end rotates. When it is desired to fix an end of the first housing 42 away from the hinge center thereof, the connecting rod 442 is rotated and is caught in the catching groove 421, and then the cam handle 443 is rotated to be closely abutted against the first housing 42. Conversely, when it is desired to release the end of the first housing 42 remote from its hinge center, the cam handle 443 is rotated to loosen it from the housing and then the link 442 is rotated to disengage it from the catch 421. This structure facilitates quick removal and quick fixing of the first housing 42.

In one embodiment, a paving device 5 is also included. Both ends of the bulletin board 3 are provided with slideways 31 along the length direction thereof, and the paving device 5 can move along the slideways 31 from the clamping mechanism 4 on one side to the clamping mechanism 4 on the other side. The paving device 5 comprises a slider 51, a second screw 52, a second nut 53 and a second spring 54. The sliding block 51 is slidably disposed on the bulletin board 3, and both ends thereof are respectively connected to the second screws 52. The second screw 52 is inserted into the slide way 31. The second nut 53 is connected to the end of the screw remote from the slide 51. The second spring 54 is sleeved on the second screw 52, two ends of the second spring respectively abut against the bulletin board 3 and the second nut 53, and in a natural state, the second spring 54 bears pressure to keep the sliding block 51 abutting against the bulletin board 3. In use, the slider 51 is slid to one side of the bulletin board 3, and one end of the poster is passed between the slider 51 and the bulletin board 3. After that, the poster is spread out by sliding the sliding block 51, so that the poster can be spread out on the bulletin board 3. This structure also makes it possible to adjust the elastic force of the second spring 54 by adjusting the second nut 53, so that the poster can be laid out more smoothly.

The working principle of the utility model is as follows:

when the poster is stuck, the box body 2 is opened. The cam handle 443 is rotated to loosen it from the housing and the link 442 is then rotated to disengage the catch 421, i.e., to release the clamping mechanism 4. The slide block 51 is then moved to the vicinity of the clamping mechanism 4 on one side, and one end of the poster is passed between the slide block 51 and the bulletin board 3, and the end of the poster is clamped by the clamping mechanism 4 on the one side. After that, the slide block 51 is slid while the poster is unfolded, so that the whole poster is spread on the bulletin board 3. And finally, the other end of the poster is clamped by the clamping mechanism 4 on the other side. The case 2 is closed.

In the specification of the present invention, a large number of specific details are explained. It is understood, however, that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
