Description

Technical Field

[0001] The utility model relates to the technical field of publicity racks, in particular to a menu publicity rack convenient for use in a cafeteria. Background Art

[0002] A publicity rack is a display device for the purpose of publicity. Its usage places are very common and it is generally used in public places such as hotels, banks, and cinemas. Among them, the cafeteria is also one of the places where publicity racks are used. A cafeteria is a public dining place. Due to the large space area of the cafeteria and the rich variety of dishes, it is difficult for diners to make choices, which will reduce the dining speed in the cafeteria. The publicity rack can display some special dishes for the cafeteria and more intuitively guide the choice direction for diners to increase the turnover rate of the cafeteria. In most cafeterias, merchants will also attract the attention of customers through sound transmission and install electronic products to replace the publicity rack, which not only consumes electricity, generates a large amount of maintenance costs in the later stage, but also is not conducive to creating a quiet and comfortable dining environment. Moreover, there may be channels for activity benefits in the cafeteria, and it is difficult for merchants to achieve full publicity. Thus, it can be seen that the publicity rack is particularly important. The publicity rack is the most direct and effective publicity path at present. It not only greatly saves the cost of attracting customers but also can achieve the expected effect.

[0003] In the prior art, the dish publicity rack is placed on both sides of the aisle or at the entrance of the cafeteria. When it is vacant, it will not only affect the overall beauty of the cafeteria but also be regarded as a swing by underage children, causing unnecessary harm. And storing it in the warehouse will occupy too much storage space and cause damage due to extrusion deformation. Moreover, in the prior art, most publicity racks are of an integral structure. The publicity poster is connected to the publicity rack through hooks at the four corners. During the transfer process, it needs to be carried as a whole, which will not only cause accidental injury incidents due to affecting the line of sight but also cause damage to the publicity support due to inconvenient migration. And when replacing the publicity poster, the operation is complex, damaging the flatness of the publicity poster or even causing it to be damaged, and it is not easy to quickly replace the publicity poster. For this reason, we propose a menu publicity rack convenient for use in a cafeteria. Content of the Utility Model

[0024] The present utility model provides a menu display rack convenient for use in the cafeteria through improvement. The technical solution of the present utility model is as follows:

[0025] As Figure 1 - Figure 5 shown, the menu display rack convenient for use in the cafeteria includes a base 1. A strip-shaped groove 2 is formed on the upper surface of the base 1, and a sliding groove 3 is formed on the lower surface of the base 1. Two sliding blocks 4 are slidably connected to the sliding groove 3. A rotating assembly 5 is rotatably connected to the lower surface of the sliding block 4. Above the strip-shaped groove 2, there are three groups of symmetrically arranged support rods 6. Two clamping blocks 7 are rotatably connected between the three support rods 6. First threaded holes 8 are formed on the side walls of the two uppermost support rods 6. The two lowermost support rods 6 are rotatably connected to the inner wall of the strip-shaped groove 2. A cross bar 9 is arranged on the first threaded holes 8. Two hexagonal blocks 10 are arranged on the periphery of the cross bar 9. A same spring 11 is arranged between the two hexagonal blocks 10. The two ends of the spring 11 are respectively fixedly connected to the side walls of the two hexagonal blocks 10. The other ends of the two cross bars 9 are provided with a same rotating shaft 12. A promotional poster 13 is pasted on the surface of the rotating shaft 12. The other end of the promotional poster 13 is pasted on the periphery of a pressing strip 14. A magnetic strip 15 is arranged on the lower surface of the pressing strip 14.

[0026] Further, the rotating assembly 5 includes a trapezoidal block 501. Connecting blocks 502 are rotatably connected to both sides of the trapezoidal block 501. Second threaded holes 503 are formed on the upper surfaces of the connecting blocks 502. Since the two side edges of the trapezoidal block 501 are inclined, the inclination angle is 45°. And spherical balls are fixedly installed at the central positions on both side edges of the trapezoidal block 501, and the spherical balls are rotatably connected to the connecting blocks 502. When the inclination angle is 45°, the vertical state transformation between the trapezoidal block 501 and the connecting blocks 502 can be realized.

[0027] Further, the height of the connecting block 502 is greater than the height of the base 1, and the width of the connecting block 502 is less than the width of the base 1. Through this setting, sufficient placement space can be reserved for the rotating shaft 12.

[0028] Further, one end of the cross bar 9 close to the first threaded hole 8 is fixedly connected with a threaded column 16. The threaded column 16 is in threaded connection with the first threaded hole 8 and the second threaded hole 503. Through this setting, in the folded state, it is convenient to store and fix the cross bar 9 and the rotating shaft 12.

[0029] Further, the hexagonal block 10 on the left is fixedly connected to the periphery of the cross bar 9, and the hexagonal block 10 on the right is slidably connected to the surface of the cross bar 9. Through this setting of the hexagonal blocks 10 on both sides of the rotating shaft 12, it is convenient for the combination and separation of the cross bar 9 and the support rod 6, and also provides sufficient sliding space for the rotating shaft 12, facilitating the installation and combination of the rotating shaft 12.

[0030] Furthermore, both the base 1 and the support rod 6 are made of metal materials. The base 1 and the support rod 6 are magnetically attracted to the magnetic strip 15. With this arrangement, the support rod 6 can be stably positioned inside the strip-shaped groove 2 when folded.

[0031] Furthermore, the length of the three support rods 6 in a Z-shaped state is less than half of the length of the strip-shaped groove 2. With this arrangement, the three support rods 6 in a Z-shaped state on both sides can be completely wrapped.

[0032] Working principle: When in use, first rotate the hexagonal blocks 10 on the left and right sides of the rotating shaft 12 to separate the first threaded hole 8 from the threaded column 16, and then remove the rotating shaft 12. Immediately afterwards, rotate the connecting blocks 502 on both sides to make the connecting blocks 502 and the trapezoidal blocks 501 form a horizontal plane. Rotate the rotating assemblies 5 symmetrically arranged on both sides until they form a vertical angle with the strip-shaped groove 2, straighten the support rods 6 in a Z-shaped state in the strip-shaped groove 2 respectively, thread the threaded column 16 on the left side with the first threaded hole 8, then sleuth the rotating shaft 12 around the circumference of the cross bar 9, insert the cross bar 9 on the right side into the rotating shaft 12, rotate the hexagonal block 10 to thread the threaded column 16 with the first threaded hole 8, stick one end of the promotional poster 13 on the surface of the rotating shaft 12, make the other end of the promotional poster 13 stick on the lower surface of the pressure strip 14, magnetically attract the lower surface of the pressure strip 14 to the upper surface of the magnetic strip 15, and then magnetically adsorb the magnetic strip 15 on the inner bottom surface of the base 1.
