Detailed implementation manners

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] As Figure 1 and Figure 2 shown, a multi-screen guide sign includes: a base 1, an installation groove is formed on the base 1, and a rotatable chassis 2 is installed in the installation groove. The chassis 2 is circular, and a worm gear 3 coaxial and rotating synchronously with it is provided at the center of its bottom surface. A worm 4 cooperating with the worm gear 3 is arranged in the base 1, a shaft rod 5 is inserted into the center of the worm 4, one end of the shaft rod 5 extends to the outside of the base 1, and a rotating handle 6 is arranged at the end of the shaft rod 5 extending to the outside of the base 1. An operator can drive the shaft rod 5 and the worm 4 to rotate through the rotating handle 6, and the worm 4 drives the worm gear 3 and the chassis 2 to rotate. Among them, the rotating handle 6 is a folding rotating handle, including a first arm 61, the bottom end of the first arm 61 is fixedly connected to the end of the shaft rod 5, a receiving groove is arranged on its side surface, a second arm 62 is arranged in the receiving groove, and the top end of the second arm 62 is hinged to the first arm 61. When in use, the second arm 62 can be rotated to be perpendicular to the first arm 61 for easy rotation.

[0022] A universal wheel 7 is arranged at the bottom of the base 1, and the universal wheel 7 is a universal wheel with a braking mechanism. The arrangement of the universal wheel 7 facilitates the movement of the entire guide sign and can improve the flexibility of the guide sign.

[0023] As Figure 1 and Figure 3 shown, a plurality of fixed outer cylinders 8 are arranged on the top of the chassis 2, and a slidable inner cylinder 9 that can be lifted is arranged in the fixed outer cylinder 8. Specifically, a circular groove is formed at the top of the sliding inner cylinder 9, and a top seat 10 is rotatably arranged in the circular groove.

[0024] Specifically, as Figure 4As shown, the fixed outer cylinder 8 has a cylindrical structure, and two positioning protrusions 17 are arranged inside. The two positioning protrusions 17 are symmetrically distributed along the diameter of the fixed outer cylinder 8 and extend from the top end to the bottom end of the fixed outer cylinder 8. A number of uniformly distributed second screw holes 18 are formed in the positioning protrusion 17. The second screw holes 18 extend from one positioning protrusion 17 to the other positioning protrusion 17 until outside the fixed outer cylinder 8. A second screw 19 is fitted in the second screw hole 18. The second screw 19 extends from the fixed outer cylinder 8 inward and can be connected with the two positioning protrusions 17 in a matching manner.

[0025] Moreover, the sliding inner cylinder 9 has a cylindrical structure, and positioning grooves 20 are formed on it corresponding to the positioning protrusions 17 to achieve the positioning of the connection between the sliding inner cylinder 9 and the fixed outer cylinder 8. At the same time, a through hole is formed at the bottom of the sliding inner cylinder 9. The through hole is arranged along the diameter direction of the sliding inner cylinder 9 and penetrates the sliding inner cylinder 9, and the through hole is located in the positioning groove 20. The second screw 19 can be inserted into the through hole to realize the fixed connection between the sliding inner cylinder 9 and the fixed outer cylinder 8. By adjusting the through hole to correspond to each second screw hole 18 respectively, the relative position between the sliding inner cylinder 9 and the fixed outer cylinder 8 can be changed, so as to adjust the height of the display screen 14.

[0026] In addition, as Figure 5 shown, the top seat 10 has a cylindrical structure, and a number of second insertion holes are formed at the bottom of it. The second insertion holes are arranged along the diameter direction of the top seat 10 and are evenly distributed along the circumferential direction of the top seat 10. The sliding inner cylinder 9 is provided with a third screw hole 21 on the side of the circular groove. The third screw hole 21 is located in the positioning groove 20, and a third screw 22 is fitted in the third screw hole 21. The third screw 22 can extend into the second insertion hole to realize the relative fixation between the top seat 10 and the sliding inner cylinder 9. When the third screw 22 is screwed out, the top seat 10 and its upper structure can be rotated to change the position of the display screen 14. When the third screw 22 is screwed in, the relative fixation between the top seat 10 and the sliding outer cylinder 9 is realized.

[0027] A curved arm 11 is arranged at the top of the top seat 10. The curved arm 11 bends away from the center of the chassis 2, and an installation through groove is formed at its top end. An installation cylinder 12 is rotatably arranged in the installation through groove. One side of the installation cylinder 12 is fixedly connected with an installation rod 13, and a display screen 14 is installed at the end of the installation rod 13. The installation cylinder 12 can rotate relative to the curved arm 11 to realize the adjustment of the inclination angle of the display screen 14.

[0028] Specifically, as Figure 6As shown, a number of first insertion holes 15 are provided on both side surfaces of the mounting cylinder 12, and the plurality of first insertion holes 15 are evenly distributed along the circumferential direction of the mounting cylinder 12. A first screw hole is provided at the top of the crank arm 11, and a first screw rod 16 is in threaded engagement with the first screw hole. The first screw rod 16 can extend into the first insertion hole 15. The number of the first screw rods 16 is two, corresponding to the first insertion holes 15 on both side surfaces of the mounting cylinder 12 respectively. When it is necessary to adjust the tilt angle of the display screen 14, rotate the first screw rod 16 to push it out of the first insertion hole 15, then rotate the mounting cylinder 12 to make another first insertion hole 15 correspond to the first screw rod 16, and then screw in the first screw rod 16 to fix it.

[0029] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
