DETAILED DESCRIPTION

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] See also Figure 1-5A construction safety production propaganda device comprises a base 1, the bottom of the base 1 is provided with a groove, and four symmetrically arranged supporting feet 2 are rotatably connected in the groove for supporting the device. An anti-skid pad 3 is provided at the bottom of each supporting foot 2 to improve the stability of the supporting foot 2. A protection box 4 is fixedly connected to the top of the base 1 to protect the propaganda component 7 to prevent the tempered glass 703 in the propaganda component 7 from colliding and breaking. Moving components 5 are installed on both sides of the protection box 4 to facilitate the movement of the device and improve the convenience of the device. A first handle 6 is fixedly connected to the upper proximal end of both sides of the protection box 4 to facilitate the carrying of the device. The top of the protection box 4 is open, and a propaganda component 7 is movably arranged in the inner cavity of the protection box 4 for propaganda work. A first mounting groove 8 is opened in the horizontal direction on both sides of the inner wall of the protection box 4, and a threaded rod 9 is rotatably connected in the first mounting groove 8 in the vertical direction. A moving block 10 threadedly connected to the threaded rod 9 is fixedly connected to the bottom proximal end of both sides of the promotion component 7. A second mounting groove 11 is opened in the vertical direction on the top of the base 1. The bottom ends of the two threaded rods 9 pass through the protection box 4 and extend into the second mounting groove 11. A driving component 12 linked to the two threaded rods 9 is arranged in the second mounting groove 11. By starting the driving component 12 to drive the threaded rod 9 to rotate, the rotation of the threaded rod 9 will drive the moving block 10 and the promotion component 7 to move upward out of the protection box 4, thereby performing the promotion work.

[0026] Furthermore, locking members 13 corresponding to the supporting legs 2 are rotatably connected to both sides of the base 1 to limit the supporting legs 2 to prevent accidental deployment when not in use.

[0027] Furthermore, the moving component 5 includes a mounting block 501 fixedly connected to both sides of the outside of the protection box 4, rotatably connected to the connecting plates 502 on both sides of the mounting block 501, a rotating shaft 503 is fixedly connected to the bottom proximal ends of the two connecting plates 502, and moving wheels 504 are installed at both ends of the rotating shaft 503. Two elastic clips 505 that are distributed up and down and matched with the rotating shaft 503 are fixedly connected to both sides of the protection box 4. The two elastic clips 505 are symmetrically distributed on the upper and lower sides of the mounting block 501. When the moving wheels 504 need to be used, the rotating shaft 503 is clamped in the elastic clip 505 at the bottom, and when the moving wheels 504 are not needed, the rotating shaft 503 is clamped in the elastic clip 505 at the top. Since the rotating shaft 503 and the elastic clip 505 are clamped together, the connection strength is not high, and it is only suitable for short-distance movement on a flat road.

[0028] Furthermore, the promotion component 7 includes a promotion box 701 movably arranged inside the protection box 4, an observation window 702 connected to the inner cavity of the promotion box 701 is provided on the front side of the promotion box 701, and tempered glass 703 is provided in the observation window 702. The coordinated use of the observation window 702 and the tempered glass 703 achieves a sealing effect to prevent rainwater from invading the inner cavity of the promotion box 701, a square slot 704 connected to the inner cavity of the promotion box 701 is provided on the right side of the promotion box 701, a first fixing plate 705 is inserted in the square slot 704, and a telescopic plate 706 inserted in the inner cavity of the promotion box 701 is fixedly connected to one side of the first fixing plate 705 for posting promotional materials, and a second handle 707 is provided on the outer side of the first fixing plate 705 to facilitate pulling out the telescopic plate 706.

[0029] Furthermore, the upper and lower sides of the telescopic plate 706 are fixedly connected to the limit blocks 14, and the upper and lower sides of the inner cavity of the promotion box 701 are provided with limit grooves 15 adapted to the limit blocks 14. The cooperation between the limit grooves 15 and the limit blocks 14 can prevent the telescopic plate 706 from detaching from the promotion box 701 when being pulled out.

[0030] Furthermore, a second fixing plate 16 is fixedly connected to the top of the promotion box 701, and two reinforcing rods 17 are fixedly connected to both sides of the bottom end of the second fixing plate 16. A circular slot 18 adapted to each reinforcing rod 17 is opened on the top of the protective box 4. The reinforcing rod 17 and the circular slot 18 can provide reinforced support when the promotion component 7 is extended for use, thereby improving the stability of the promotion component 7.

[0031] Furthermore, the driving assembly 12 includes a rotating rod 1201 rotatably connected to the second mounting groove 11 in a horizontal direction, two first gears 1202 are installed on the rotating rod 1201, a second gear 1203 meshingly connected to the first gear 1202 is installed at the bottom end of the threaded rod 9, a third gear 1204 is installed in the middle of the rotating rod 1201, and a fourth gear 1205 meshingly connected to the third gear 1204 is rotatably connected inside the second mounting groove 11, a rotating handle 1206 is provided on the outer side of the base 1, and anti-slip grooves are provided on the rotating handle 1206 to improve the convenience of rotating the handle 1206, the rotating handle 1206 is connected to the fourth gear 1205 through a connecting shaft, and when the rotating handle 1206 is rotated, the fourth gear 1205 will be driven to rotate, and at the same time, the fourth gear 1205 will drive the third gear 1204, the rotating rod 1201 and the two second gears 1203 to rotate, and the second gear 1203 will drive the first gear 1202 and the threaded rod 9 to rotate.

[0032] When in use, the device is moved to the desired working location through the moving wheel 504, and then the locking piece 13 is rotated to open, and the four supporting legs 2 are rotated outward and unfolded respectively. Then the staff lifts one side of the device through the first handle 6, takes out the rotating shaft 503 from the elastic clamp 505 below, turns the moving wheel 504, the rotating shaft 503 and the connecting plate 502 upward together, and fixes the rotating shaft 503 in the elastic clamp 505 above. Then the device lifts the other side and repeats the above operation. At this time, the four supporting legs 2 will contact with the ground, and the device will be operated. The fourth gear 1205 is driven to rotate by rotating the rotating handle 1206. At the same time, the fourth gear 1205 drives the third gear 1204, the rotating rod 1201 and the two second gears 1203 to rotate. The second gear 1203 drives the first gear 1202 and the threaded rod 9 to rotate. The rotation of the threaded rod 9 drives the moving block 10 and the promotion component 7 to move upward out of the protection box 4. After that, the promotion work can be carried out. During transportation, the promotion component 7 is put into the protection box 4 for protection to prevent the tempered glass 703 from being exposed to the outside and being bumped and broken.

[0033] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
