Example one

Referring to fig. 1, the present invention is a propaganda rack, which includes a propaganda frame 1, wherein the propaganda frame 1 is a rectangular frame structure, and a propaganda poster 9 is placed inside the propaganda frame 1. The lower extreme fixedly connected with supporting seat 101 of propaganda frame 1, the front of propaganda frame 1 is installed and is observed the clear glass of poster 9 content.

Referring to fig. 1-2, a clamping mechanism adapted to display different posters in different sizes is fixedly connected to the inside of the advertisement frame 1, the clamping mechanism includes four "L" shaped corner clamping blocks 2 and an elastic rope 5, one end of the elastic rope 5 is fixedly connected to the corners of the "L" shaped corner clamping blocks 2, and the other end of the elastic rope 5 is fixedly connected to four corners of the inner wall of the advertisement frame 1. The L-shaped corner clamping block 2 comprises a corner clamping block A201 and a corner clamping block B202, a plurality of round holes are formed in the inner surface of the corner clamping block A201, a plurality of cylinders matched with the round holes are fixedly connected to the inner surface of the corner clamping block B202, and the heads of the cylinders are sharp parts with a puncturing function. When the poster is fixed, the cylinders of the corner clamping blocks B202 firstly puncture the four corners of the poster, then the round holes on the corner clamping blocks A201 are sleeved on the cylinders to be compressed, namely, the corners of the poster 9 are clamped and fixed through the corner clamping blocks A201 and the corner clamping blocks B202. After the fixing, the elastic string 5 is contracted, that is, the poster 9 is completely unfolded by stretching the four corners of the poster 9.

Referring to fig. 1 and 3, a dust removing mechanism for removing dust on the surface of the transparent glass is fixedly installed on the front surface of the advertisement frame 1. Dust removal mechanism includes scraper blade 6, crank 7 and screw drive subassembly 4, and crank 7 rotates with propaganda frame 1's front to be connected, scraper blade 6 and transparent glass's surface sliding connection, and the both ends and the 4 threaded connection of screw drive subassembly of scraper blade 6, crank 7 pass through screw drive subassembly 4 and drive scraper blade 6 and go up and down, and 6 up-and-down motion of scraper blade can strike off the dust on transparent glass surface. Wherein, screw drive assembly 4 includes horizontal transfer line 401 and two vertical threaded rods 402, and two vertical threaded rods 402 rotate to be connected in the both sides of propaganda frame 1, and the both ends fixedly connected with threaded sleeve 601 of scraper blade 6, threaded sleeve 601 and the meshing of vertical threaded rod 402. One end of the horizontal transmission rod 401 is in meshing transmission with the crank 7 through a bevel gear 403, and the other end of the horizontal transmission rod 401 is in meshing transmission with the vertical threaded rod 402 through the bevel gear 403. When a reader rotates the crank 7, the horizontal transmission rod 401 drives the vertical threaded rod 402 to rotate forwards or backwards, and the threaded sleeves 601 at the two ends of the scraper 6 ascend or descend along the vertical threaded rod 402, so that the function of scraping dust by the up-and-down movement of the scraper 6 is realized.

A protective cover is fixedly mounted on the peripheral side of the vertical threaded rod 402 and the peripheral side of the horizontal transmission rod 401. On one hand, the function damage caused by the fact that sundries are rolled in the rotating process of the vertical threaded rod 402 and the horizontal transmission rod 401 is avoided. On the other hand, safety accidents such as clamping injury and the like caused by the fact that the body of a person contacts with a rotating part are avoided.

One end of the elastic rope 5 is fixedly connected with the middle part of the I-shaped edge clamping block 3, and the other end of the elastic rope 5 is fixedly connected with the inner wall of the propaganda frame 1. The I-shaped edge clamping blocks 3 and the L-shaped corner clamping blocks 2 are uniformly clamped at the edge of the poster 9, so that on one hand, the poster 9 is uniformly stressed, and the phenomenon that the poster 9 is torn and damaged due to the stretching process of the elastic rope 5 is avoided; on the other hand, the uniformly arranged I-shaped edge clamping blocks 3 and L-shaped corner clamping blocks 2 are equivalent to that a circle of edge wrapping is added on the edge of the poster 9, so that the attractiveness of the poster 9 is improved.

EXAMPLE III

Referring to fig. 5, the upper surface of the scraper 6 is provided with a sliding groove 602, and the sliding groove 602 is slidably connected with the magnifying glass 8. The magnifying glass 8 can move up and down along with the scraper 6 and also can move on the scraper 6, so that characters at any position on the poster 9 can be magnified, and people with poor eyesight can read conveniently. The cross section of the sliding groove 601 is of a convex shape, and the lower end of the magnifier 8 is matched with the cross section of the convex shape, so that the magnifier 8 is prevented from falling off from the sliding groove 602.

Example four

Referring to fig. 6 and 7, a door 103 is provided on the back of the advertisement frame 1 for replacing the poster 9 and cleaning the impurities inside the advertisement frame 1. The top of the propaganda frame 1 is fixedly connected with a rain-shielding top cover 102, so that rainwater is prevented from dripping into the propaganda frame to wet the poster 9, and the characters on the poster 9 are blurred or damaged; meanwhile, the rain-proof top cover 102 adopts a rural eave style, and can better integrate local landscape features.
