DETAILED DESCRIPTION

[0029] The following is a combination of specific implementation cases and attached Figures 1 to 7 The present invention is further described below, but the present invention is not limited to these embodiments.

[0030] See also Figures 1 to 7 As shown, a municipal road construction warning device includes a base 1 and a display screen 17. A first column 2 is rotatably provided at the top of the base 1. A second column 3 is pluggably embedded in the inner cavity of the first column 2. By adjusting the overall height of the first column 2 and the second column 3, the height of the entire device is adjusted to facilitate the storage of subsequent devices. A support base 5 is fixedly installed at the top of the second column 3. The support base 5 has a through cavity from left to right. The inner cavity of the support base 5 is provided with an adjustment unit for driving the display screen 17 to adjust the tilt angle.

[0031] See also Figures 2 to 4As shown, the adjustment unit includes a mounting plate 6 fixedly mounted on the inner cavity of the support seat 5 in the vertical direction, the outer wall of the mounting plate 6 is rotatably connected with a rotating shaft 7 through a bearing, and the rotating shaft 7 is rotatably connected to the inner wall of the through cavity of the support seat 5 through a bearing, a rotating wheel 8 is fixedly mounted on the outer wall of the rotating shaft 7, and a plurality of limiting holes 11 are opened on the outer wall of the rotating wheel 8 along the circumferential direction, and the spacing angles between two adjacent limiting holes 11 are equal, and a limiting rod 10 is pluggable and embedded in the inner cavity of one of the limiting holes 11, and the limiting rod 10 penetrates the outer wall of the mounting plate 6 from front to back, a support arm 16 is fixedly mounted on the outer wall of the rotating shaft 7, and the support arm 16 is fixedly connected to the display screen 17, and the limiting rod A first spring 12 is sleeved on the outer wall of 10, and the two ends of the first spring 12 are respectively connected to the outer wall of the mounting plate 6 and the outer wall of the limiting rod 10. As the rotating wheel 8 rotates, the limiting rod 10 embedded in the inner cavity of the limiting hole 11 is forced to disengage from the inner cavity of the limiting hole 11 corresponding to this moment, and the first spring 12 is forced to be compressed. When the rotating wheel 8 rotates to the next position where the limiting hole 11 is aligned with the limiting rod 10, the elastic force of the first spring 12 causes the limiting rod 10 to be embedded in the inner cavity of the limiting hole 11 corresponding to this moment, so as to realize the positioning of the rotating wheel 8 after rotation, that is, the positioning of the rotating shaft 7, the supporting arm 16 and the display screen 17 after rotation can be realized.

[0032] Specifically, one end of the limiting rod 10 embedded in the inner cavity of the limiting hole 11 is set as an inclined end surface, so as to ensure that when the limiting rod 10 is rotated 8, it can automatically detach from the inner cavity of the corresponding limiting hole 11 at this time without additional steps.

[0033] See also Figure 2 and Figure 3 As shown, limiting claws 9 are equidistantly arranged on the side wall of the rotating wheel 8 in the circumferential direction, a mounting seat 13 is installed on the inner wall of the support seat 5, a positioning claw 14 is rotatably connected to the outer wall of the mounting seat 13, and the free end of the positioning claw 14 is embedded in the space between two adjacent limiting claws 9, a second spring 15 is installed on the outer wall of the positioning claw 14, and the second spring 15 is fixedly connected to the inner wall of the support seat 5. With the rotation of the rotating wheel 8, the limiting claw 9 on the outer wall of the rotating wheel 8 can prompt the positioning claw 14 to be pushed outward to achieve compression of the second spring 15. When the rotating wheel 8 and the limiting claw 9 stop rotating, the second spring 15 is used to prompt the positioning claw 14 to be embedded in the gap between two adjacent limiting claws 9, so as to achieve the limiting of the limiting claw 9 and the rotating wheel 8 after rotation, and avoid the situation where the limiting claw 9 and the rotating wheel 8 are prompted to rotate counterclockwise under the action of gravity of the display screen 17.

[0034] See also Figure 1 , Figures 5 to 7As shown, the outer wall of the second column 3 is provided with a plurality of insertion holes 19 equidistantly along the vertical direction, and the outer wall of the first column 2 is provided with a pluggable embedded pin 20, and the pin 20 is inserted into the inner cavity of one of the insertion holes 19. When the total length of the first column 2 and the second column 3 is adjusted, the adjusted positioning of the first column 2 and the second column 3 can be achieved by inserting the pin 20 into the inner cavity of the insertion hole 19.

[0035] See also Figures 5 to 7 As shown, a placement groove 18 is provided on the upper surface of the base 1, and a rotating rod 21 is fixedly installed at the bottom end of the outer wall of the first column 2, and the rotating rod 21 is rotatably connected to the inner wall of the placement groove 18. Four through holes are equidistantly provided on the outer wall of the rotating rod 21 along the circumferential direction, and each two through holes form a group to form a through channel, and a positioning rod 23 is inserted into the inner cavity of one group of through holes. A positioning hole 22 is provided at the bottom end of the inner wall of the placement groove 18, and the bottom end of the positioning rod 23 is embedded in the inner cavity of the positioning hole 22. The positioning rod 23 is pulled out of the outer wall of the rotating rod 21, and the first column 2 is rotated to cause the first column 2 to be embedded in the inner cavity of the placement groove 18, so as to fold the device as a whole and further reduce the volume occupied by the device. After adjustment, the positioning rod 23 is re-penetrated through the outer wall of the rotating rod 21 and inserted into the inner cavity of the positioning hole 22 to realize the positioning of the folded first column 2 in the inner cavity of the placement groove 18.

[0036] In addition, universal wheels 24 are respectively installed at the four corners of the bottom end of the base 1, and the entire device can be moved to a desired position with the help of the universal wheels 24.

[0037] In order to ensure that the folded first column 2 and the second column 3 can be stably placed, the length of the placement groove 18 is adapted to the height of the first column 2, thereby ensuring that when the second column 3 is embedded in the inner cavity of the first column 2 and then folded and stored, it can be completely embedded in the inner cavity of the placement groove 18.

[0038] The working principle of a municipal road construction warning device in this embodiment is as follows:

[0039] When the inclination angle of the display screen 17 is adjusted according to the place of use, the display screen 17 is driven to drive the support arm 16 to rotate in the clockwise direction. At this time, the rotating shaft 7 fixedly connected to the outer wall of the support arm 16 drives the rotating wheel 8 to rotate synchronously clockwise. With the rotation of the rotating wheel 8, the limiting rod 10 embedded in the inner cavity of the limiting hole 11 is forced to disengage from the inner cavity of the limiting hole 11 corresponding to this time, and the first spring 12 is forced to be compressed. When the rotating wheel 8 rotates to the limiting hole 11 at the next position and aligns with the limiting rod 10, the elastic force of the first spring 12 causes the limiting rod 10 to be embedded in the inner cavity of the limiting hole 11 corresponding to this time. In order to realize the positioning of the rotating wheel 8 after the rotation, that is, the positioning of the rotating shaft 7, the supporting arm 16 and the display screen 17 after the rotation can be realized; at the same time, as the rotating wheel 8 rotates, the limiting claw 9 on the outer wall of the rotating wheel 8 can cause the positioning claw 14 to move outward, thereby realizing the compression of the second spring 15. When the rotating wheel 8 and the limiting claw 9 stop rotating, the positioning claw 14 is forced to be embedded in the gap between two adjacent limiting claws 9 by means of the second spring 15, so as to realize the limiting of the limiting claw 9 and the rotating wheel 8 after the rotation, thereby avoiding the situation where the limiting claw 9 and the rotating wheel 8 are forced to rotate counterclockwise under the gravity of the display screen 17;

[0040] When the device is stored or transported after use, the latch 20 is pulled out of the corresponding inner cavity of the socket 19. At this time, the second column 3 and the first column 2 lose their positioning function, and the second column 3 is inserted downward into the inner cavity of the first column 2 to reduce the overall height of the device; the positioning rod 23 is pulled out of the outer wall of the rotating rod 21, and the first column 2 is rotated to make the first column 2 embedded in the inner cavity of the placement groove 18, so as to fold the device as a whole and further reduce the volume occupied by the device. After adjustment, the positioning rod 23 is re-through the outer wall of the rotating rod 21 and inserted into the inner cavity of the positioning hole 22 to realize the positioning of the folded first column 2 in the inner cavity of the placement groove 18, and the device as a whole can be moved to the desired position with the help of the universal wheel 24;

[0041] The utility model can adjust the inclination angle of the display screen 17. When there are road construction warnings with up and down slopes, the inclination angle of the display screen 17 can be flexibly adapted to warning locations in different situations, so that the warning content can be seen at the first time, further ensuring the construction warning effect. In addition, the overall height of the equipment is reduced, and the folded equipment can be stored through the placement slot 18, reducing the overall space occupied by the equipment, which is more conducive to the transportation and storage of the equipment.

[0042] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
